AI Technical Summary
When existing lighting devices are equipped with sealed shells to block rainwater erosion, it is difficult to dissipate heat, which affects the service life of the lamp.
A protective cover plate is designed including a lamp body, a cover plate, a sealed airbag and a heat dissipation hole. A sealed airbag is installed on the top of the cover plate, and a heat dissipation hole with high inside and low inclined outside is opened on all sides. The sealing and fixing of the cover plate and the lamp body is achieved through the snapping assembly.
The seal between the cover plate and the lamp body is realized to prevent rainwater from seeping in. At the same time, the design of the heat dissipation hole and guide plate ensures that the lamp body can effectively dissipate heat and extends the service life of the lamp.

Technical Field
[0001] The utility model relates to the technical field of lamps, and in particular to a protective cover plate of a lighting device. Background Art
[0002] The protective cover is a kind of lighting device accessory, that is, a cover set outside the bulb to focus light or protect the internal parts of the lamp body, so most lamps have protective covers. At present, lighting devices used outdoors are generally equipped with sealed shells to prevent rain erosion, but lighting devices will generate a lot of heat during the light-emitting process. If this heat cannot be dissipated in time, it will affect the service life of the lamp. Utility Model Content
[0003] The utility model provides a protective cover plate for a lighting device, which is designed to solve the problem that heat dissipation is difficult and the service life of the lamp is affected when a sealed shell is provided in the prior art to prevent rainwater erosion.
[0004] The technical solution is as follows: A protective cover plate of a lighting device includes a lamp body, a mounting groove is provided on the lamp body, a cover plate is clamped on the mounting groove, a sealing airbag is installed on the top of the cover plate and is located in the mounting groove, heat dissipation holes with an inner high and an outer low inclined setting are provided on all four sides of the cover plate, and a clamping component is provided on the cover plate for fixing the cover plate to the lamp body.
[0005] Preferably, the positioning assembly includes mounting blocks fixedly connected to four sides of the cover plate, each mounting block is fixedly connected to a clamping block via a spring, and clamping holes corresponding to the clamping blocks are opened on the four sides of the lamp body.
[0006] Preferably, the outer side of the block is arranged as an inclined surface.
[0007] Preferably, a guide plate is further included, which is arranged on the outside of the cover plate and above the heat dissipation hole.
[0008] Preferably, a square rod is further included, which is slidably connected to the lamp body, and pressure blocks located in the clamping holes are fixedly connected to the four sides of the square rod.
[0009] Preferably, the pressing block extends into the clamping hole to cooperate with the inclined surface of the clamping block.
[0010] The beneficial effects of the utility model are as follows: when the airbag contacts the top of the installation groove, the airbag is deformed by the squeezing force of the cover plate to fill the installation groove and wrap the top of the cover plate, thereby sealing the joint between the cover plate and the lamp body to prevent rainwater from seeping into the interior. The lamp body dissipates heat through the heat dissipation holes, and the guide plate and the heat dissipation holes that are inclined with the inner side higher and the outer side lower can prevent rainwater from entering the cover plate.

[0017] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.
[0018] Example 1
[0019] A protective cover plate for a lighting device, referring to Figure 1-Figure 5 , including a lamp body 1, a mounting groove 3 is opened on the lamp body 1, a cover plate 2 is clamped on the mounting groove 3, a sealing airbag 4 is installed on the top of the cover plate 2, the sealing airbag 4 is located in the mounting groove 3, heat dissipation holes 41 are opened on four sides of the cover plate 2, the heat dissipation holes 41 are inclined with the inner side higher and the outer side lower, and a clamping assembly is set on the cover plate 2, and the clamping assembly is used to fix the cover plate 2 on the lamp body 1.
[0020] The clamping assembly includes a mounting block 5, which is fixed to the four sides of the cover plate 2. Each mounting block 5 is fixed with a clamping block 52 through a spring 51. The outer side of the clamping block 52 is arranged with an inclined surface. Clamping holes 53 are opened on the four sides of the lamp body 1, and the clamping holes 53 correspond to the clamping blocks 52 one by one.
[0021] The cover plate 2 further includes a guide plate 42 , which is disposed outside the cover plate 2 and above the heat dissipation hole 41 .
[0022] It also includes a square rod 54 which is slidably connected to the lamp body 1 . Four sides of the square rod 54 are fixedly connected with pressing blocks 55 . The pressing blocks 55 are located in the clamping hole 53 . The pressing blocks 55 extend into the clamping hole 53 and cooperate with the inclined surface of the clamping block 52 .
[0023] When installing the cover plate 2, the cover plate 2 is docked with the mounting groove 3 of the lamp body 1. When the clamping block 52 enters the mounting groove 3, the clamping block 52 is squeezed and contracts inward, and the spring 51 is compressed. When the clamping block 52 corresponds to the clamping hole 53, the clamping block 52 is driven to move outward and reset in the clamping hole 53 under the action of the spring 51. The installation of the cover plate 2 is completed. At the same time, when the cover plate 2 is docked with the mounting groove 3 of the lamp body 1, the airbag on the cover plate 2 enters the mounting groove 3. When the airbag contacts the top of the mounting groove 3, the airbag is deformed and filled by the squeezing force of the cover plate 2. The installation groove 3 wraps the top of the cover plate 2 to achieve sealing at the joint between the cover plate 2 and the lamp body 1 to prevent rainwater from seeping into the inside. The lamp body 1 dissipates heat through the heat dissipation holes 41, and the set guide plate 42 and the heat dissipation holes 41 set at an angle with the inside higher and the outside lower can prevent rainwater from entering the cover plate 2. When the cover plate 2 needs to be removed, the square rod 54 is moved down, and the square rod 54 drives the pressure block 55 to move downward. The pressure block 55 is squeezed by the outer side of the card block 52 to move inward, and the spring 51 is compressed to make the card block 52 disengage from the card hole 53, and the cover plate 2 can be removed.
[0024] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
