[0002] LED lens is an optical element that is closely integrated with LED. Its main function is to enhance the efficiency of light use and luminous efficiency by changing the propagation path and distribution of light. It is usually made of high temperature resistant materials to ensure that it can withstand the high temperature when the LED is working. Silicone lens is not only resistant to high temperature, but can also be directly packaged on the LED chip through reflow soldering, so that the LED lens is closely integrated with the LED light source.

[0003] LED lenses are widely used in LED light sources, such as LED car lights, stage lights, etc., wherein the stage lights need to be installed on a fixing frame to ensure stability during use. Existing stage lights are mostly fixed to the fixing frame supporting the stage lights by fastening bolts. When the fixing frame needs to be disassembled and assembled, it takes a lot of time. In addition, due to excessive use of fastening bolts, the fastening bolts are prone to roll off during the disassembly process, affecting the tightness of the connection between the LED lens and the fixing frame.

DETAILED DESCRIPTION

[0021] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0022] Example: Figures 1 to 4 As shown, the utility model is an LED lens fixing frame that is easy to replace, including a base 1, a frame 2 is fixedly arranged on the top surface of the base 1, and an LED lens body 3 is installed between the frame 2, and the LED lens body 3 can be separated from the frame 2, so that the frame 2 is easy to replace to adapt to usage scenarios with different needs, such as replacing the frame 2 with a higher base 1, or disassembling and repairing a damaged frame 2.

[0023] The back of the frame 2 is provided with a mounting groove 9, in which a bidirectional screw 5 is rotatably arranged, and two square plates 6 are symmetrically arranged on the bidirectional screw 5, and a connecting plate 7 is fixedly connected to the top of the square plate 6, and a clamping block 8 is fixedly arranged on the opposite surface of the connecting plate 7; one end of the bidirectional screw 5 is rotated to penetrate the outside of the frame 2 and is fixedly arranged with an adjustment knob 4. When the adjustment knob 4 is rotated, the adjustment knob 4 drives the bidirectional screw 5 to rotate, and the two square plates 6 on the bidirectional screw 5 move in a direction of approaching each other, thereby driving the connecting plate 7 to approach each other, and then the clamping block 8 on the connecting plate 7 can be clamped into the LED lens body 3, so that the frame 2 and the LED lens body 3 can be installed.

[0024] This method can realize the quick installation of the frame 2 and the LED lens body 3, and also facilitates the quick disassembly of the frame 2 and the LED lens body 3, and then replaces the frame 2. When disassembling, it is only necessary to rotate the adjustment knob 4 in the opposite direction, so that the two square plates 6 on the bidirectional screw 5 are separated from each other, and the block 8 is separated from the LED lens body 3.

[0025] The middle of the frame 2 is provided with a second installation groove for installing the LED lens body 3, and both sides of the second installation groove on the frame 2 are provided with through grooves 10 for the card block 8 to pass through. The size of the through groove 10 is larger than the card block 8, so that the card block 8 can enter and exit the through groove 10 easily.

[0026] The inner bottom surface of the mounting groove 1 9 is provided with a slide groove, and a sliding block is fixedly provided at the bottom end of the square plate 6, and the sliding block is slidably arranged in the slide groove. In the process of the movement of the square plate 6, the sliding block slides in the slide groove to play a guiding role.

[0027] The two ends of the LED lens body 3 are respectively fixed with connecting pieces 12, and a square groove for engaging with the block 8 is provided in the connecting piece 12, and the connecting piece 12 and the block 8 are fixed by two upper and lower clamping rods 14. The block 8 is provided with a clamping groove 11 from top to bottom, and the connecting piece 12 is provided with a clamping groove 2 13 from top to bottom. The clamping groove 11 and the clamping groove 2 13 are of the same size, and when the block 8 is engaged with the square groove, the clamping groove 11 and the clamping groove 2 13 are located on the same straight line. The walls of the clamping grooves 11 and 13 are connected with a sliding groove 15, and the sliding groove 15 is stepped. A slider 16 is fixedly provided on the clamping rod 14, and the slider 16 is slidably connected with the sliding groove 15.

[0028] When the clamping rod 14 passes through the through slot 10 and is clamped into the first clamping slot 11, the clamping rod 14 can be passed through the second clamping slot 13 and the first clamping slot 11. During the clamping process, the slider 16 on the clamping rod 14 rotates along the sliding groove 15. The provided sliding groove 15 can prevent the clamping rod 14 from detaching from the first clamping slot 11 and the second clamping slot 13, thereby enhancing the tightness of the connection.

[0029] The two clamping rods 14 are provided with magnet blocks 17 at their ends close to each other, and the two magnet blocks 17 are magnetically attracted. When the two clamping rods 14 are both inserted into the clamping slot 11 and the clamping slot 2 13, the magnet blocks 17 on the two clamping rods 14 are attracted to each other, further enhancing the tightness of the connection.

[0030] During operation, the LED lens body 3 is connected to the frame 2 by the clamping block 8 and the square groove, and then fixed by the upper and lower clamping rods 14, which can prevent the clamping block 8 from separating from the square groove, thereby enhancing the tightness of the connection between the frame 2 and the LED lens body 3. When disassembly is required, the clamping rod 14 is first taken out, and then the adjusting knob 4 is rotated to drive the bidirectional screw 5 to rotate, so that the square plate 6 on the bidirectional screw 5 drives the connecting plate 7 and the clamping block 8 on the connecting plate 7 to separate from the square groove, and through the cooperation between the clamping block 8, the square groove and the clamping rod 14, the LED lens body 3 and the frame 2 can be quickly disassembled and assembled, thereby facilitating the replacement of the frame 2.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
