Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 This utility model provides a technical solution for a waterproof lighting fixture for public places: a waterproof lighting fixture for public places includes a lighting fixture 8, which includes a lamp body 81 and a connecting cable 82. The lamp body 81 is covered by a lampshade 1, the lampshade 1 is covered by a top cover 4, and the lampshade 1 is covered by a bottom cover 3. The lampshade 1, the bottom cover 3, and the top cover 4 are tightened and positioned by multiple sets of positioning screws 2 arranged circumferentially. The lampshade 1 is provided with multiple sets of guide sleeves 10 arranged circumferentially to be adapted to the positioning screws 2. The bottom cover 3 is provided with a first flange seat 31 arranged circumferentially to be adapted to the positioning screws 2. The top seat 4 is provided with a second flange seat 41 that is adapted to the positioning screw 2 along its circumference. By using the adaptation of the guide sleeve 10, the first flange seat 31, the second flange seat 41 and the positioning screw 2, when the lamp cover 1, the cover base 3 and the cover top seat 4 are assembled as a whole, the bolts of the positioning screw 2 are used to tighten and fix them, and the lamp cover 1, the cover base 3 and the cover top seat 4 are assembled as a whole, and the lamp body 81 is sealed and covered to achieve waterproof function. Moreover, the integrated combination of the lamp cover 1, the cover base 3, the cover top seat 4 and the positioning screw 2 also has a good anti-collision and impact protection function, and can effectively resist external bumps and impacts.

[0026] A sealing ring 9, which passes through the positioning screw 2, is provided between the lampshade 1 and the cover base 3, as well as between the lampshade 1 and the cover top seat 4. The sealing ring 9 includes a sealing flange seat 91 that is adapted to the guide of the positioning screw 2. Sealing gaskets 92 are provided at the upper and lower ends of the ring seat of the sealing flange seat 91, and the sealing gaskets 92 extend into the interior of the lampshade 1, the cover base 3, and the cover top seat 4, respectively. Sealing rings 92 are provided at the upper and lower ends of the lampshade 1, the seat surface of the cover base 3, and the seat surface of the cover top seat 4. The sealing groove that matches the gasket 92, while assembling the waterproof lamp fixture as a whole, provides a tight seal between the lampshade 1 and the cover base 3, and between the lampshade 1 and the cover top seat 4. With the bolts of the positioning screw 2 tightened and positioned, the lampshade 1 and the cover base 3 press against the sealing ring 9, and the lampshade 1 and the cover top seat 4 press against the sealing ring 9, thus improving the overall sealing performance of the lamp fixture cover structure.

[0027] A conduit 5 for the connecting cable 82 is installed above the support of the top cover 4, and a fixing seat 6 is installed at the other end of the conduit 5.

The compression sleeve 7 includes a compression ring 71 and a cable traction groove 72 opened in the middle of the core sleeve of the compression ring 71. The cable traction groove 72 is a conical groove structure. By using the guiding traction of the cable traction groove 72 in the compression sleeve 7, the interface of the connecting cable 82 is sealed and filled. Then, when the fixing seat 6 is assembled with the external public facilities, the compression of the compression sleeve 7 is used to perform self-sealing of the wiring outlet to improve the sealing and waterproof characteristics of the lamp.

[0028] Both the extrusion sleeve 7 and the sealing ring 9 are made of natural rubber. By setting the extrusion sleeve 7 and the sealing ring 9 to natural rubber, they have good elastic deformation characteristics and can deform and be squeezed during lamp assembly, better filling the gaps in lamp assembly and achieving the all-round waterproof function of the lamp.

[0029] The working principle of this utility model is as follows: During the production and assembly of waterproof lamps, the sealing ring 9 is sequentially placed between the lampshade 1 and the cover base 3, and between the lampshade 1 and the cover top seat 4.

The integrated combination of the assembled lampshade 1, cover base 3, cover top seat 4, and positioning screw 2 also has good anti-collision and impact protection performance, and can effectively resist external bumps and impacts.

[0030] Then, by using the guiding pull of the cable pulling groove 72 in the compression sleeve 7, the interface of the connecting cable 82 is sealed and filled to complete its assembly. Furthermore, when the fixing seat 6 is used to assemble it with the external public facilities, when the fixing seat is fixed on the public facilities, the compression of the compression sleeve 7 is used to perform self-sealing of the wiring lead-out part, further improving the sealing and waterproof characteristics of the lamp.

[0031] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
