[0027] See also Figure 1-3 , an anti-falling lamp cover, comprising a main structure, the main structure comprising a fixing structure;

[0028] The main structure includes a lamp cover body 1, a moving tube 2 is arranged on the right side of the lamp cover body 1, symmetrical fixing devices 3 are arranged on the left and right sides of the inner wall of the lamp cover body 1, and a clamping ring 4 is arranged at the bottom of the inner wall of the lamp cover body 1;

[0029] The fixing structure includes a fixing device 3, a connecting block 5 is provided on the top of the fixing device 3, a fixing rod 6 is rotatably connected to the top of the connecting block 5, a limiting block 7 is fixedly connected to the bottom of the fixing rod 6, a spring 8 is fixedly connected to one side of the fixing rod 6 close to the lamp cover body 1, and a fixing block 9 is provided on the other side of the fixing rod 6.

[0030] In this embodiment, the movable tube 2 is used to connect the power cord; slide rails 10 are provided on the upper and lower sides of the movable tube 2, and a slider 11 corresponding to the slide rails 10 is provided at the connection between the lamp cover main body 1 and the movable tube 2. A tube cover 12 is rotatably connected to the right side of the movable tube 2, and the tube cover 12 is used to prevent dust and other debris from entering the interior of the lamp cover main body 1.

[0031] The slide rail 10 and the slider adopt ball-type linear slide rails, which have the advantages of high rigidity, high precision, long life, infinite cycle motion and optimized design. The transmission interface between the slide rail 10 and the slider 11 is provided with steel balls, and the steel balls are matched with appropriate sizes between the slider 11 and the slide rail 10 to restrain the slider 11 on the slide rail 10, so that the slider 11 can move linearly along the slide rail 10 at high speed and high precision. The end points on both sides of the slide rail 10 are provided with limit end points, and the limit end points are used to prevent collision to achieve the purpose of safety.

[0032] In this embodiment, the limit block 7 is used to limit the rotation range of the fixing rod 6 to prevent the fixing rod 6 from rotating too much; the inside of the limit block 7 is hollow, and the hollow shape facilitates the movement of the fixing rod 6; a groove is provided on the side of the limit block 7 close to the middle of the lamp cover body 1 to allow the fixing block 9 to pass through; the spring 8 is used to push the fixing rod 6 so that the fixing rod 6 fits more closely to the lamp to be fixed, and one side of the spring 8 is fixedly connected to the lamp cover body 1, and the other side is fixedly connected to the fixing rod 6.

[0033] In this embodiment, a rotating shaft 13 is provided at the connection between the connecting block 5 and the fixing rod 6, and rebounders 14 are provided on the left and right sides of the rotating shaft 13. The rebounder 14 is used to push the fixing rod 6 so that the fixing rod 6 can better fit the lamp to be fixed. A rebound spring and a spring column are provided inside the rebounder 14.

[0034] One side of the rotating shaft 13 is fixedly connected to the connecting block 5, and the other side of the rotating shaft 13 is fixedly connected to the fixing rod 6. The connecting block 5 is connected to the fixing rod 6 by rotating through the rotating shaft 13. The rebound spring wraps the spring column. When the rebounder 14 is subjected to the pressure from the fixing rod 6, the spring will be compressed. When the spring is compressed, it will store the potential energy brought by the pressure, and the potential energy of the spring will push the fixing rod 6 toward the direction of the lamp.

[0035] It should be noted that: the clamping ring 4 is used to clamp and fix the lamp to be fixed; the fixing block 9 is a structure used to fix the lamp to be fixed, and the fixing block 9 has a certain softness. While ensuring stable fixation, the certain softness can avoid damage to the lamp.

[0036] The working principle of the above embodiment is:

[0037] When the anti-falling lamp cover is in use, the lamp to be fixed is placed inside the lamp cover body 1. First, the lamp is fixed by the clamping ring 4, and then the fixing device 3 further reinforces the fixed lamp. When the fixing device 3 is fixed, the insertion of the lamp will cause the fixing rod 6 to move toward the outside through the rotating shaft 13. At this time, the spring 8 and the rebounder 14 will be compressed. When they are compressed, they will store the potential energy brought by the pressure, and the potential energy will push the fixing rod 6 toward the direction of the lamp. The movement of the fixing rod 6 drives the movement of the fixing block 9, so that the fixing block 9 can fix the lamp to be fixed; after the fixing is completed, the power cord can be connected through the moving tube 2. When the moving tube 2 is used, the slider 11 is moved on the slide rail 10, so that the moving tube 2 can be moved to a desired position. After the movement is completed, the tube cover 12 is covered. The tube cover 12 can prevent dust and other debris from entering the inside of the lamp cover body 1.

[0038] Beneficial effects of the above embodiments:

[0039] 1. The anti-falling lamp cover, through the use of a fixing structure, allows the lamp to be fixed by the clamp ring 4 and further reinforced and fixed by the fixing device 3, thereby avoiding the problem of the lamp falling off when it is shaken, greatly enhancing the anti-falling property of the device and making the device more stable.

[0040] 2. The anti-drop lamp cover is installed inside the lamp cover by means of the fixing device 3, thus avoiding the problem of the outer convex support occupying a large area, and making the anti-drop lamp cover more convenient for storage and transportation.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
