Detailed Description

The present invention will be further described with reference to the accompanying drawings and the following detailed description.

The utility model provides a lamp shell end cover, as shown in figures 1 and 2, which comprises an end cover body 2, a first buckling block 5, a second buckling block 6 and a fixing seat 9, wherein the end cover body 2 is a plate-shaped structure, the plate-shaped structure extends towards the periphery to form a mounting part which is similar to a guide surface, the mounting part is provided with a relevant hole or a buckling piece, a fastening piece such as a screw and the like is assembled in the hole, the end cover body 2 is connected with the lamp shell 1 through the mounting part, so that the end cover body 2 is supported and fixed at the end part of the lamp shell 1, the end cover body 2 is provided with an axial through hole 11, namely, the axial through hole 11 is arranged along the length direction between the end cover bodies 2 at two ends of the lamp shell 1, the axial through hole 11 is used as a channel for connecting an external circuit and also used as a cavity for embedding the end cover body 2, the end cover body 2 is provided with a clamping groove 3, the clamping groove 3 is communicated with the axial through hole 11, and the buckling block and the clamping groove 3 are embedded and form sliding fit, so that the buckling block can move up and down along the clamping groove 3 to realize the matching or the separation of the first buckling block 5 or the second buckling block 6 and the end cover body 2.

First buckle piece 5 and second buckle piece 6 all include the buckle body 7 and set up pothook 8 on the buckle body 7, pothook 8 quantity is two and sets up relatively, 4 quantity in pothook 8 groove are also corresponding for two, 8 one ends of pothook are connected in the peripheral face of the buckle body 7, the other end then inserts 8 inslots of pothook 4 and forms the card and pulls, the buckle spare of first buckle piece 5 or second buckle piece 6 removes to and cooperates the back completely with draw-in groove 3 in draw-in

groove

3, 8 tip of pothook then are located and correspond 8 inslots of pothook and form the buckle.

The hook 8 can be fixed to the buckle body 7 in addition, or extend from the face of the buckle body 7 as a whole, in this embodiment, each hook 8 extends from the periphery of the buckle body 7, and the face inserted into the hook groove 4 and the hook groove 4 is an arc face, the arc faces are towards the outer sides of two sides of the buckle body 7, the hook 8 includes a hook 8 arm, the arc face is connected to the buckle body 7 through the hook 8 arm, the arc face is the face of one end of the hook 8 arm, in this embodiment, the length of the hook 8 arm is shorter, but has a certain elastic deformation, when the first buckle block 5 or the second buckle block 6 moves in the buckle groove 3 and is matched with the end cover body 2, the arc face of the hook 8 is compressed, the hook 8 arm is deformed, the arc face tightly abuts against the inner wall of the buckle groove 3, the arc face and the inner wall of the buckle groove 3 are in point connection, so that the resistance is very small and labor-saving in the moving process, until first buckle piece 5 or second buckle piece 6 and end cover body 2 complete coordination back, the arcwall face of pothook 8 gets into pothook groove 4, and the arcwall face card is in pothook groove 4 in the time, the pressure of pothook 8 arcwall face not receiving draw-in groove 3 inner walls, pothook 8 reconversion, pothook 8's arcwall face inserts completely to pothook groove 4 in, the final pothook 8 and pothook groove 4 complete clamping coordination. When the buckle block needs to be disassembled, only a downward pulling force needs to be applied to the buckle body 7, and the arc-shaped surface of the hook 8 is extruded by the edge of the hook 8 and elastically deforms inwards, so that the hook 8 is separated from the hook groove 4.

In addition, the fixing seat is located the bottom of first buckle piece 5 or

second buckle piece

6, and 9 one ends of the fixing seat compress tightly the buckle piece, and 9 shapes of the fixing seat can follow lamp housing 1 to make adaptability adjustment, and the fixing seat and first buckle piece 5 or second buckle piece 6 are fixed through ultrasonic welding, and when adopting this kind of connected mode, the fixing seat, first buckle piece 5 and second buckle piece 6 are the working of plastics together. The fixing seat 9 can also be in other integrated processing forms with the end cover, the fixing seat 9 extends towards the lamp housing 1 to form an installation part for connecting and fixing the lamp housing 1, in the embodiment, the installation part is provided with a threaded hole, and the fixing between the fixing seat 9 and the lamp housing 1 is realized through a fastener connection mode.

In this embodiment, as shown in fig. 3, the top surface of the inside of the slot 3 is semicircular and the semicircular opening faces downward, the corresponding surface of the locking body 7 is also semicircular, and after the semicircular shapes are mutually matched, the stability is better, and a gap is not easy to be generated between the slot 3 and the locking block.

The periphery of the buckle body 7 is provided with a limiting step 10 with a certain thickness, the limiting step 10 extends out from the periphery of the buckle body 7, the trend of the limiting step 10 is identical to that of the clamping groove 3, when the buckle body 7 is completely matched with the end cover body 2, the limiting step 10 is matched with the surface of the clamping groove 3, which is located outside the end cover, at the moment, the surface of the buckle body 7 is flush with the surface of the end cover body 2, and the buckle body 7 is attractive and not easy to fall off.

It should be noted that, the first fastening block 5 and the second fastening block 6 are two separate fastening blocks, except for the difference of no hole, the rest structures and the shapes are kept consistent, and the fastening blocks and the end cover body 2 are in one-to-one correspondence when being fastened, as shown in fig. 4, a hole 12 communicated with the axial through hole 11 is formed on the second fastening block 6, the first fastening block 5 has no hole 12, the second fastening block 6 is generally used between the two lamp housings 1, and the hole 12 is used as a channel for connecting a wire between the two lamps; first buckle piece 5 then is applicable to 1 both ends of lamp body, usually as sealed effect, consequently, according to 1 tip different positions of lamp body, can select first buckle piece 5 or second buckle piece 6, not only simple structure, the die sinking is convenient moreover.

The fixing seat, the first buckling block 5 and the second buckling block 6 are plastic parts, the fixing seat 9 and the first buckling block 5 or the second buckling block 6 can be fixedly connected through ultrasonic welding, and the fixing seat 9 and the first buckling block 5 or the second buckling block 6 are connected into a whole, so that the fixing seat 9 and the first buckling block 5 or the fixing seat and the second buckling block 6 are directly clamped on the end cover body 2, and the assembly and disassembly are very convenient.

While the above is directed to the preferred embodiment of the present invention, it is not intended that it be limited, except as by the appended claims.
