At present, electric fan generally includes ceiling fan, pole fan, desk fan, etc. No matter what kind of fan it is, the blade is all consisted of blade and blade bracket. In existing technology, fan blade and blade bracket are generally fixed together by screws or rivets, which make the handling way complicated during assembling. Furthermore, if the blade needs to be replaced, a screwdriver becomes a necessity to remove the screws. Under the situation that the screws are rusty, it will be hard to replace the blade; while if the riveting structure is adopted, the blade even can't be replaced, which causes much inconvenience to the user.
- To solve the above-mentioned shortcomings of complicated assembling and inconvenient replacement, this invention provides a new blade structure which connects the blade and blade bracket by the inserting structure. The structure is simple and convenient to assemble and disassemble.
- The technology project this invention adopts to solve the technology issues is: A kind of fan blade which can be assembled and disassembled easily, composing the blade and blade bracket, which are assembled together by the inserting structure.
- The further technology projects which this invention adopts to solve the technology issues further include:
- The above-mentioned inserting structure composes two or more elastic connectors and equal or more mounting holes. The elastic connectors are set on the blade bracket while the mounting holes are on the blade. The positions of the elastic connectors and mounting holes are matched.
- The above-mentioned inserting structure composes two or more elastic connectors and equal or more mounting holes. The elastic connectors are set on the blade while the mounting holes are on the blade bracket. The positions of the elastic connectors and mounting holes are matched.
- The above-mentioned elastic connectors are installed on the blade bracket by screws.
- The above-mentioned elastic connectors are installed on the blade by screws.
- The above-mentioned elastic connector has joint part in front, and the joint part has two or more elastic inserters.
- The above-mentioned elastic inserters are wedge-shaped in front and have stoppers in the end.
- The beneficial effects of the invention are: In this invention, the blade and blade bracket are joined together by the inserting structure. During assembling, we only need to align the mounting holes with the elastic connectors and press downwards forcibly. In this way, the blade could be securely installed on the blade bracket. In this invention, screws are unnecessary for installing the blade on the blade bracket. When it comes to the necessity of disassembling the blade, only a press plate with matched holes is needed to press the above-mentioned elastic connectors and separate the blade from the blade bracket, which could greatly enhance the ease of use.

- The following preferred embodiments are just priority ways for this invention. Any other embodiments of same or similar principle and basic structure are all under protection scope of this invention.
- Please refer to
FIG. 1 toFIG. 6 . The invention mainly comprises blade bracket 1 andblade 2, the blade bracket 1 andblade 2 are joined together by the inserting structure. Below is detailed display for this invention by introducing several preferred embodiments. - Please refer to
FIG. 1 toFIG. 4 . The structures inFIG. 1 toFIG. 4 are for this embodiment. Any other embodiments in this specification introduced later that have similar structures as embodiment one are not displayed by attached figures. In this embodiment, there are threemounting holes 3 on theblade 2 and three elastic connectors 4 on the blade bracket 1. The elastic connectors 4 could insert into themounting holes 3 on theblade 2 and fix theblade 2 to the blade bracket 1. In this embodiment, there are threemounting holes 3 and three matched elastic connectors 4. In actual practice, they could be set as two or more according to actual requirement. And the quantity ofmounting holes 3 could be equal or more than the quantity of elastic connectors 4. There are mounting holes on the bottom centre of the elastic connectors 4 in this embodiment. And the elastic connectors 4 are installed on the blade bracket 1 by screws 5. In actual practice, elastic connectors 4 could be installed on the blade bracket 1 by inserting or riveting or other ways. There is ajoint part 41 on the bottom of the elastic connector 4. In this embodiment, there are threeelastic inserters 42 on theelastic joint 41 and there is space between two adjacentelastic inserters 42. In actual practice, theelastic inserters 42 could be set two or more. There arestoppers 421 on the bottom edge ofelastic inserters 42. As theelastic inserters 42 insert into themounting hole 3, thestoppers 421 are wedged on the edge of themounting hole 3, which keepsblade 2 and blade bracket 1 relatively fixed. In this embodiment, in order to make theelastic inserters 42 insert into themounting hole 3 easily, theelastic inserters 42 are designed to be wedge-shaped in front. To be specific, the front of theelastic inserters 42 is similar to the shape of a cone with the front smaller and the end bigger, which make them easily wedge into. - The structures for this embodiment are similar to embodiment 1. The differences are: The elastic connectors 4 are installed on the
blade 2 while the mountingholes 3 are installed on the blade bracket 1. Other structures are as same as what described in embodiment 1. - During assembling of this invention, we first fix the elastic connectors 4 on the blade bracket 1 or
blade 2, and then align the mountingholes 3 with the elastic connectors 4 and press downwards forcibly to securely fix theblade 2 and blade bracket 1 together. In this invention, screws are unnecessary for installing theblade 2 on the blade bracket 1. The process of assembling is fast and the inserting structure is firm and reliable. When it comes to the necessity of disassembling theblade 2, only a press plate 6 of matched holes with elastic connectors 4 is needed to press the elastic connectors 4 and make theelastic inserters 42 retract to the center, which achieves the separation of theblade 2 from the blade bracket 1. - In this invention, the blade and blade bracket are joined together by the inserting structure. Screws are unnecessary for installing the blade on the blade bracket. The process of assembling is fast and the inserting structure is firm and reliable. When it comes to the necessity of disassembling the blade, only a press plate with matched holes is needed to press the above-mentioned elastic connectors and separate the blade from the blade bracket, which could greatly enhance the ease of use.
