Description
Technical field
The present invention relates to a kind of ball cover, relate in particular to a kind of headend equipment of safety defense monitoring system---the ball cover of clipping the ball peripheral hardware.
Background technology
Clipping the ball is that light harvesting is learned, electronics, machinery, information processing is in one, by camera, power transmission, motion control device, graphical analysis based on the high-speed parallel processing, identification, compression is partly formed a kind of headend equipment of safety defense monitoring system with communicating by letter etc., because of it has video camera, Position Control, orientation and camera presets, moving object detection, identification and tracking, multiple functions such as flame and Smoke Detection warning are applied in the building more and more, bank, the airport, the station, customs, traffic, electric power, industrial enterprise, and the people can't be on duty the safety monitoring occasion in place.
Because the video camera working temperature is-5 ℃～45 ℃ in the clipping the ball, when exceeding this temperature range video camera work, can influence picture quality, even damage video camera, therefore being installed in outdoor clipping the ball generally all needs to be covered with protective cover, and outdoor protective cover sealing is high, enters to avoid rainwater, to adapt to various weather conditions, as wind, rain, snow, frost; So generally in the gap of last cover and following cover, sandwich an O RunddichtringO 3, the diameter of sealing ring is greater than the gap, pass through interference fit, make the sealing ring distortion, reach sealing purpose, as shown in Figure 1, but this sealing means has the following disadvantages: 1) must be grease-added when sealing ring is installed, last cover could close up smoothly with following cover, and because of lacking lubricating grease, last cover is difficult to close up with following cover during later maintenance, the maintenance personal often removes O RunddichtringO 3 and directly will go up cover and play cover to close up, and brings the sequelae of poor sealing; 2) last cover and the diameter and the circularity of covering down there is the higher requirement of ratio, last cover and the gap of covering down are too small to be installed not advance, excessive sealing is bad, shown in Fig. 2,3, and circle that cover will be very up and down that contacts with sealing ring and inwall require very level and smooth, otherwise just be difficult to form tight the contact, influence sealing effectiveness with sealing ring.The high speed ball cover generally adopts the repressed elongation moulding of aluminium sheet, after machine cuts is made but at present,, aluminium sheet can produce at inwall when extensional and draw trace (being commonly called as wrinkle), expect smooth inwall, must increase processing cost through the secondary operations polishing.
Summary of the invention
The present invention overcomes above-mentioned weak point, purpose is to provide a kind of high-speed ball cover, this ball cover is resisted against on the plane of inner cover bottom by the top of sealing ring, the another side of sealing ring is resisted against on the inwall of mounting groove, sealing ring forms sealing and contacts with inwall, inner cover, thereby realize reaching sealing purpose, simple, the easy for installation and good sealing effect of this sealing device structure has solved problems of the prior art.
The present invention achieves the above object by the following technical programs: a kind of high-speed ball cover comprises cover, following cover, sealing device; Last cover comprises cover cap, double-deck case, and the cover cap lid is located on the double-deck case, and described double-deck case comprises outer cover and inner cover, and inner cover is set in the outer cover; Following cover comprises that translucent cover circle, translucent cover, translucent cover are fixed on the translucent cover circle; Described sealing device comprises sealing ring, sealing ring, connecting ring, several screws; Described connecting ring is fixed on the inner cover sidewall, the screwed hole and the screw that are provided with in the connecting ring are complementary, described sealing ring is arranged in the mounting groove on the translucent cover circle, screw in the through hole on the translucent cover circle is fixed on sealing ring in the mounting groove, sealing ring is arranged on the sealing ring, an end that contacts with sealing ring at sealing ring is provided with the cannelure that a cross section is a circular arc, the outer downside of sealing ring is resisted against on the cannelure, the top of sealing ring is resisted against on the plane of inner cover bottom, and the another side of sealing ring is resisted against on the inwall of mounting groove; Several screws pass the screwed hole that is provided with in through hole and the connecting ring on the translucent cover circle and are threaded.
As preferably, several screws are four.
As preferably, described sealing ring is the O RunddichtringO.
As preferably, on the translucent cover circle, be provided with some roads projection, described some roads projection is arranged near the junction of translucent cover and translucent cover circle.
As preferably, described projection is a semi-cylindrical hill.
As preferably, described some roads projection is the twice projection.
Beneficial effect of the present invention: this sealing device structure of establishing in the high-speed ball cover that the present invention describes is simple, do not need grease-added during installation, last cover just can close up smoothly with following cover, can not exist when not having lubricating grease during later maintenance yet, last cover is difficult to close up with following cover, the maintenance personal removes the O RunddichtringO and directly will go up cover and play cover to close up, and brings the problem of the sequelae of poor sealing; The high-speed ball cover of this structure is less demanding with the diameter and the circularity of covering down to last cover, the low and good sealing effect of processing cost.
