This utility model uses a bracket made of high-toughness, opaque material to fix the lens to the PCB board via clips, thereby reducing the processing difficulty and material limitations of the lens, and improving the production and installation efficiency of the lens.

[0003] Although the above-mentioned devices have many advantages, they still have some shortcomings in actual use.

[0004] 1. Although the above-mentioned device is made of a high-toughness, opaque material for the support frame, in actual use, after a long period of use, the material will also undergo irreversible deformation due to the device's own deformation for locking. This will lead to a situation where the locking is not secure, thus affecting the overall performance of the device.

[0005] 2. In the above-mentioned device, when fixing the lens, the lens needs to be pushed into the bracket during the process of fixing the lens using the locking block. The lens can only be locked in place by the deformation of the bracket. However, during this process, the locking block needs to rub against the lens, which can easily cause wear to the side wall of the lens, thereby affecting the lens's performance.

A locking plate 69 is provided inside the fixing device 6 to lock the locking block 66.

[0030] The above structure, by providing light-blocking cotton 5, can block light and prevent other light from entering the interior of the lens body 3 from below; at the same time, when the bracket body 1 is damaged, the light-blocking cotton 5 can also block the light entering the interior of the lens body 3 from the outside.

[0031] The locking device 2 includes a connecting rod 21, a locking block 22 is rotatably connected to the outside of the connecting rod 21, a return spring 23 is installed in the middle of the connecting rod 21, one end of the return spring 23 is fixedly connected to the locking block 22, the other end of the return spring 23 is fixedly connected to the connecting rod 21, and the connecting rod 21 is fixedly connected to the bracket body 1.

[0032] The above structure, by providing a return spring 23, with one end of the return spring 23 fixedly connected to the locking block 22 and the other end of the return spring 23 fixedly connected to the connecting rod 21, allows the portion of the locking block 22 near the inside of the bracket body 1 to rotate downward and fit against the bracket body 1 when the return spring 23 is in a stationary state and the lens body 3 is not installed inside the bracket body 1.

[0033] By pressing the part of the locking block 22 away from the inside of the bracket body 1, the return spring 23 retracts. By pressing the four locking blocks 22 outwards simultaneously with a tool, the operator can insert the lens body 3 into the inside of the bracket body 1, avoiding frictional contact during the installation process. After installation, slowly release the pressure on the locking block 22, allowing the locking block 22 to enter the inside of the connecting groove 4. At this point, the installation of the lens body 3 is completed, and wear on the side wall of the lens body 3 can be avoided.

[0034] The fixing device 6 includes a connecting chamber 60. A slider 61 is slidably connected inside the left connecting chamber 60. A first sliding frame 62 is fixedly connected to the upper and lower right sides of the slider 61. A second sliding frame 63 is slidably connected to the right side of the first sliding frame 62. Telescopic springs 64 are fixedly connected to the upper and lower sides inside the slider 61. A pressing block 65 is fixedly connected to the upper left side of the slider 61. A locking block 66 is fixedly connected to the lower part of the slider 61. A knob 67 is rotatably connected to the left side of the connecting chamber 60. A moving screw 68 is fixedly connected to the right side of the knob 67. The right side of the moving lead screw 68 is threaded with a locking plate 69. The other end of the telescopic spring 64 is fixedly connected to the connecting chamber 60. The pressing block 65 is slidably connected to the connecting chamber 60. The moving lead screw 68 is rotatably connected to the connecting chamber 60. The locking plate 69 is slidably connected to the connecting chamber 60. The second sliding frame 63 is located inside the connecting chamber 60 and is fixedly connected to the connecting chamber 60. The connecting chamber 60 is located below the bracket body 1 and is fixedly connected to the bracket body 1. The lens body 3 corresponds to the lamp bead 9. The locking block 66 is engaged with the slot 8.

[0035] The above structure has fixing devices 6 on both the left and right sides of the bracket body 1, and the internal structure of the fixing devices 6 on both the left and right sides is the same and symmetrical to each other.

[0036] By rotating the knob 67, the moving screw 68 is rotated. The right side of the moving screw 68 is threaded with a locking plate 69, which is slidably connected to the connecting chamber 60. This causes the moving screw 68 to move the locking plate 69 left and right. When the locking plate 69 contacts the slider 61, the slider 61 cannot slide into the connecting chamber 60 due to the pressure from the connecting chamber 60, the moving screw 68, and the locking plate 69. This locks the slider 61, which in turn locks the locking block 66. At this point, the locking block 66 is tightly engaged with the slot 8.

[0037] By rotating knob 67, when the right surface of locking plate 69 contacts the right inner wall of connecting chamber 60, the operator can simultaneously press the left and right pressing blocks 65. Pressing the pressing blocks 65 causes slider 61 and locking block 66 to move simultaneously towards the center of connecting chamber 60, allowing the operator to disassemble bracket body 1. In summary, this achieves locking and disassembly of bracket body 1 without deforming locking block 66.

[0038] By providing a slider 61, with the diameter of the opening inside the slider 61 being larger than the diameter of the moving screw 68 but smaller than the diameter of the circular block in the middle of the locking plate 69, the slider 61 does not participate in the rotation of the moving screw 68, and the locking plate 69 can effectively resist the slider 61.

[0039] As shown in the figure, the front and rear sides of the connecting chamber 60 are provided with sliding grooves, and the locking plate 69 is slidably connected to the sliding grooves. Through the mutual sliding action of the two, the moving screw 68 can stably drive the locking plate 69 to move left and right.

[0040] Working principle: When using this type of snap-on bracket to fix the lens, first turn the knob 67 so that the locking plate 69 and the connecting chamber 60 are in contact on three sides at the same time. At this time, the operator presses the compression blocks 65 on the left and right sides at the same time. Then the operator inserts the locking block 66 into the slot 8. At this time, the installation of the bracket body 1 is completed. After the installation is completed, turn the knob 67 again so that the locking plate 69 is in contact with the slider 61. At this time, the slider 61 is locked, that is, the locking block 66 is locked. At this time, the installation of the bracket body 1 is completed.

[0041] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
