Abstract

The utility model relates to an improvement of spraying tool closing component structure, which comprises a spraying gun body and a jetting cap, a paint cup, an adjust press system and an adjusting flux system, which is sleeved respectively at the spraying gun body by thread connection; wherein, the screw thread between the jetting cap, the paint cup, the adjust press system and the adjust flux system corresponding closing component with the praying gun body is multithread the screw, which has the advantages of rapid and effortless closing component or disassembling, and convenience for assembly using or disassembling cleaning.

Description

Spray painting tool screw togather improved structure

Technical field

The utility model relates to a kind of Spray painting tool, refers to the improvement structure of the screw-joining structures such as spray cap, lacquer cup, pressure-regulating portion and accent flow portion in a kind of spray gun of the usefulness of spraying paint especially, the structure that can make above-mentioned each part finish combination or dismantle with the spray gun body fast.

Background technology

See also shown in existing Spray painting tool (spray gun) three-dimensional exploded view of Fig. 4, it is mainly constructed and includes a spray gun body 40, on described spray gun body 40, screw togather the spray cap 41 of installing respectively, lacquer cup 42, pressure-regulating portion 43 is formed with accent flow portion 44, and described spray cap 41, lacquer cup 42, pressure-regulating portion 43 with transfer flow portion 44 respectively with spray gun body 40 on corresponding sealed thread structure, all be a kind of fine thread structure of single helical on the market at present, the tooth number that is each inch is many, the little structure of screw pitch (helical pitch), and each screw-joining structure must have enough screwed distances just to have enough adaptations, stability and bond strength, and longer its tooth number of screwed distance is the more; Therefore, described existing Spray painting tool is to the sealed of above-mentioned each part or dismounting the time, and it must rotate several circles just can finish purpose sealed or dismounting, causes and wastes man-hour; Again, cause screw pitch wherein is less, the angle of inclination that is screw thread is less, so will be in the time of after it is locked, will opening again than effort, especially after using, between screw thread, be stained with and stick when some paint are arranged, be difficult to especially outward winding, cause in use quite inconvenience, so to the existing necessity of improvement again that is configured with.

This case utility model designer is because the disappearance that the sealed structure of the spray gun body of above-mentioned existing Spray painting tool and spray cap, lacquer cup, pressure-regulating portion and accent flow portion is wasted time and energy, the whence studies intensively, and long-pending individual is engaged in the many years of experience of described cause, designs a kind of improved structure that screws togather of brand-new Spray painting tool eventually.

Summary of the invention

At the deficiencies in the prior art, the purpose of this utility model is: the improved structure that screws togather that a kind of Spray painting tool is provided, it combines spray gun body and spray cap, lacquer cup, pressure-regulating portion and accent flow portion etc., have fast, the labour-saving is sealed or the dismounting effect, use or disassembly, cleaning and be convenient to assembling.

For achieving the above object, the technical solution adopted in the utility model is:

A kind of Spray painting tool screw togather improved structure, it is characterized in that: include a spray gun body, on described spray gun body, screw togather spray cap, lacquer cup, pressure-regulating portion and the accent flow portion of installing respectively; It is characterized in that:

Described spray cap, lacquer cup, pressure-regulating portion and accent flow portion respectively with the spray gun body on corresponding sealed thread structure, be multi start thread.

Compared with prior art, adopt the advantage that the utlity model has of technique scheme to be:

The structure of going up according to this is described, adds and is twice above and be arranged in parallel because the structure of wherein said multi start thread (two screw threads, triple thread ...) is a screw pitch with each road screw thread; When the screwed distance of the tooth number when described multi start thread is per and existing single thread structure is identical with the tooth number, the structure of described multi start thread can reduce the number of turns of rotation more than 1/2 or 2/3, and can finish the assembly and disassembly speed of above-mentioned each part fast; In addition, be twice abovely because of the screw pitch of each screw thread wherein becomes, so the angle of inclination of described screw thread is bigger, it is less to cause horizontal component required when dismounting, labour-saving effect relatively when reaching dismounting.

The specific embodiment

For making your juror further understanding and understanding be arranged, lift a possible embodiments now and cooperate graphic being described in detail as follows structure of the present utility model, device and feature thereof:

At first see also shown in Figure 1, Spray painting tool of the present utility model screw togather improved structure, mainly structure includes a spray gun body 10, forms with accent flow portion 14 with the spray cap 11 that screws togather installing on described spray gun body 10 respectively, lacquer cup 12, pressure-regulating portion 13; It is characterized in that: described spray cap 11, lacquer cup 12, pressure-regulating portion 13 and accent flow portion 14 respectively with spray gun body 10 on the thread structure of corresponding latched position, be multi start thread.

The structure of going up according to this is described, adds and is twice above and be arranged in parallel because the structure of wherein said multi start thread (two screw threads, triple thread ...) is a screw pitch with each road screw thread; Again as shown in Figure 2, described figure is the schematic diagram of a kind of pair of thread structure, and it is to be made of the first road screw thread 21 and the second road screw thread 22 that two roads be arranged in parallel, and the screw pitch H of each screw thread, compare with the structure of existing single thread (as Fig. 3), it is two times of screw pitch h of described single thread; The tooth number of tooth number when described multi start thread is per and existing single thread structure and screwed distance homogeneous phase are simultaneously, the structure of described multi start thread can reduce the number of turns (triple thread or quadruple thread then can reduce by 2/3～3/4 the number of turns) of rotation 1/2, and can finish the assembly and disassembly speed of above-mentioned each part fast; In addition, be twice abovely because of the screw pitch H of each the road screw thread in two screw threads becomes, so the tilt angle theta of described screw thread is bigger, it is less to cause horizontal component required when dismounting, and can compare the labour-saving effect when reaching dismounting.

More than explanation is just illustrative for the utility model, and it is nonrestrictive, those of ordinary skills understand, under the situation of the spirit and scope that do not break away from claim and limited, can make many modifications, variation or equivalence, but but all will fall within the claim restricted portion of the present utility model.

Claims

A Spray painting tool screw togather improved structure, it is characterized in that: include a spray gun body, on described spray gun body, screw togather spray cap, lacquer cup, pressure-regulating portion and the accent flow portion of installing respectively; It is characterized in that:

Described spray cap, lacquer cup, pressure-regulating portion and accent flow portion respectively with the spray gun body on corresponding sealed thread structure, be multi start thread.
