[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This specific embodiment is a protective cover for lighting fixtures, such as... Figure 1-4 As shown, the lighting fixture protective cover includes a mounting base 1. A threaded fixing seat 3 is protruding from the center of the top of the mounting base 1. A lamp body 4 is installed at the threaded fixing seat 3. A fixing ear 2 is protruding from the outer side of the mounting base 1. A fixing hole 21 is provided through the fixing ear 2. The fixing ear 2 can be used to facilitate the auxiliary positioning of the mounting base 1 during operation.

[0027] An annular groove 13 is formed near the outer edge of the top of the mounting base 1. A protective cover body 5 is mounted on the annular groove 13. An annular groove 62 is formed at the outer edge of the mounting base 1. A protective frame 6 is snapped into the annular groove 62. The protective frame 6 is cylindrical. Support rings are fixed at equal intervals on the outer side of the protective frame 6. The top of the protective frame 6 is a cross-shaped frame. A snap-fit ​​groove 7 is formed at the top of the annular groove 62. A protruding seat 61 is provided at the bottom of the protective frame 6. The vertical cross section of the protruding seat 61 is T-shaped. The protruding seat 61 and the snap-fit ​​groove 7 are engaged. The snap-fit ​​groove 7 includes an insertion port for inserting the protruding seat 61 and an arc-shaped groove for snap-fitting and fixing the protruding seat 61. The mounting base 1 is connected to the insertion interface. A sliding cavity is opened inside the mounting base 1, and a positioning component 8 is installed in the sliding cavity. A positioning hole is opened at the bottom of the protective frame 6. The positioning hole and the positioning component 8 are positioned together. The positioning component 8 includes a guide rod 9 that is vertically fixed in the sliding cavity. A protruding plate 11 is sleeved on the guide rod 9. A protruding block is provided on the outer side of the protruding plate 11. A through groove is opened on the outer side of the mounting base 1 for the protruding block to pass through. A plug post 12 is fixed at the top of the protruding plate 11. The top of the plug post 12 extends out of the annular groove 62. The plug post 12 is inserted into the positioning hole. An ejector spring 10 is sleeved on the guide rod 9 to assist the protruding plate 11 in pushing.

[0028] Through the cooperation between the protruding seat 61 at the bottom of the protective frame 6, the snap-fit ​​groove 7, and the positioning component 8, during installation, pressing the protruding block causes the protruding plate 11 to be pressed down as a whole. During the pressing down of the protruding plate 11, the ejector spring 10 is compressed, thereby causing the insert post 12 to retract as a whole. The protruding seat 61 is then inserted into the insertion port in the snap-fit ​​groove 7. Rotating the protective frame 6 clockwise causes the protruding seat 61 to rotate as a whole, thereby causing the protruding seat 61 to be inserted into the arc-shaped groove of the snap-fit ​​groove 7. This completes the overall positioning and fastening of the protective frame 6. This allows for quick disassembly and replacement of the protective frame 6 after damage to the internal lamp body 4, improving the overall replacement efficiency of the lamp body 4 and minimizing problems such as the inconvenience of disassembling the protective frame 6 when replacing the lamp body 4.

[0029] The annular groove 13 is symmetrically provided with slots 131, which are L-shaped. A snap-fit ​​block 51 is provided on the inner side of the protective cover body 5, and the snap-fit ​​block 51 and the slot 131 are engaged and snap-fitted together.

[0030] By cooperating with the protective cover body 5 and the snap-fit ​​block 51, as well as the annular groove 13 and the snap-fit ​​slot 131, located on the outer edge of the lamp body 4, the snap-fit ​​block 51 on the protective cover body 5 can be snapped into the snap-fit ​​slot 131 during operation. When the protective cover body 5 is reversed, the snap-fit ​​block 51 rotates and snaps into the snap-fit ​​slot 131, thus completing the overall positioning and fastening of the protective cover body 5. This also facilitates effective protection of the lamp body 4 during operation, minimizing direct contact between the lamp body 4 and rainwater when it is outdoors, thus effectively protecting the lamp body 4.

[0031] Working principle:

[0032] During operation, the bottom thread of the lamp body 4 is installed in the threaded fixing seat 3, and the snap-fit ​​block 51 on the protective cover body 5 is snapped into the slot 131. Reverse the protective cover body 5. When the protective cover body 5 rotates, it drives the snap-fit ​​block 51 to rotate and snaps into the slot 131, thus completing the overall positioning and fastening of the protective cover body 5. During installation, press the protruding block and drive the protruding plate 11 to press down as a whole. During the pressing down of the protruding plate 11, the ejector spring 10 is compressed, thereby causing the insert post 12 to retract as a whole. Insert the protruding seat 61 into the insertion port in the snap-fit ​​slot 7. Rotate the protective frame 6 in the forward direction. The protective frame 6 drives the protruding seat 61 to rotate as a whole, thereby inserting the protruding seat 61 into the arc-shaped groove of the snap-fit ​​slot 7, thus completing the overall positioning and fastening of the protective frame 6.
