Description

Technical Field

[0001] This utility model belongs to the field of optical lens technology, and specifically relates to optical lenses used in lamps. Background Technology

[0002] In the field of lighting fixtures, optical lenses are important optical components. Their function is to refract and reflect the light emitted by the light source in order to achieve the desired light distribution effect and improve the utilization rate of light and the quality of lighting.

[0003] The prior art patent publication number CN202120861748.6 describes an LED lighting optical lens. This patent includes an optical lens body and an embedding ring. The outer surface of the optical lens body is a convex arc-shaped curved surface, and the inner surface is a concave arc-shaped curved surface. The inner cavity of the optical lens body accommodates the light source on the lighting fixture mounting plate. This utility model provides an LED lighting optical lens. Through a series of structural designs and uses, this utility model, by using magnetic positioning posts and magnetic positioning cylinders, utilizes the mutual attraction of opposite magnetic poles to avoid the phenomenon that, during long-term use, the fatigue resistance of the spring decreases, leading to poor fixing effect. Furthermore, it avoids the increased labor intensity caused by the need for external force to compress the spring for elastic deformation. Moreover, it can also provide heat dissipation when installed with the lighting fixture plate, thus improving the practicality of the LED lighting optical lens. However, in actual use, the following shortcomings still exist: From a practical standpoint, the structure of this LED lighting optical lens is relatively simple, and it is inconvenient to disassemble, inspect, and replace it during installation.

[0004] Therefore, there is a need for optical lenses for lighting fixtures to solve the problem that existing optical lenses for lighting fixtures are inconvenient to disassemble, inspect, and replace during installation. Utility Model Content

[0005] The purpose of this invention is to provide an optical lens for lighting fixtures to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an optical lens for a lamp, comprising a mounting plate, a fixing mechanism, an optical lens body, and an L-shaped mounting base. The mounting plate has an internal mounting groove, the fixing mechanism is disposed on the bottom surface of the mounting plate, the optical lens body is fixedly mounted inside the mounting groove by the fixing mechanism, and the L-shaped mounting base is symmetrically fixedly connected to the top of the mounting plate and connected to the external structural surface through the L-shaped mounting base.

[0007] It should be noted in the solution that the fixing mechanism consists of a connecting seat, a cylinder, a rotating block, a connecting plate, a fixed shaft, an L-shaped connecting block, a connecting shaft, a connecting rod, a fixed plate, and a moving column. The connecting seat is fixedly connected to the left side of the bottom surface of the mounting plate, the fixed end of the cylinder is rotatably connected to the front of the connecting seat, the rotating block is fixedly connected to the output end of the cylinder, and the connecting plate is rotatably connected to the top of the rotating block.

[0008] It is worth noting that there are four fixed shafts, which are symmetrically fixed to the four corners of the bottom surface of the mounting plate. The L-shaped connecting block is rotatably connected to the outside of the fixed shafts, and the connecting shafts are fixedly connected to the bottom surfaces of the two sides of the L-shaped connecting block.

[0009] It should be further noted that there are four connecting rods, and the two ends of each connecting rod are rotatably connected to the outside of two connecting shafts.

[0011] In a preferred embodiment, there are four fixed plates, which are symmetrically fixed to the four sides of the bottom surface of the mounting groove of the mounting plate. The movable column passes through the fixed plate and is slidably connected to the fixed plate. The side of the movable column near the connecting rod is set as an arc-shaped surface.

[0012] In a preferred embodiment, the optical lens body has symmetrical mounting holes around its upper perimeter that are adapted to the movable column.

[0013] Compared with the prior art, the optical lens for lamps provided by this utility model has at least the following beneficial effects:

[0020] The present invention will be further described below with reference to the embodiments.

[0021] Please see Figure 1-3 This utility model provides an optical lens for lamps, including a mounting plate 1, a fixing mechanism 2, an optical lens body 3, and an L-shaped mounting base 5. The mounting plate 1 has an internal mounting groove. The fixing mechanism 2 is disposed on the bottom surface of the mounting plate 1. The optical lens body 3 is fixedly installed inside the mounting groove through the fixing mechanism 2. The L-shaped mounting base 5 is symmetrically fixedly connected to the top of the mounting plate 1 and is connected to the external structural surface through the L-shaped mounting base 5.

[0022] The entire optical lens structure is connected and fixed to the external structural surface by the L-shaped mounting bases 5 symmetrically arranged above the mounting plate 1, thus realizing the assembly of the lamp.

[0023] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the fixing mechanism 2 consists of a connecting seat 201, a cylinder 202, a rotating block 203, a connecting plate 204, a fixed shaft 205, an L-shaped connecting block 206, a connecting shaft 207, a connecting rod 208, a fixed plate 209, and a moving column 210. The connecting seat 201 is fixedly connected to the left side of the bottom surface of the mounting plate 1. The fixed end of the cylinder 202 is rotatably connected to the front of the connecting seat 201. The rotating block 203 is fixedly connected to the output end of the cylinder 202. The connecting plate 204 is rotatably connected above the rotating block 203.

[0024] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that there are four fixed shafts 205, which are symmetrically fixed to the four corners of the bottom surface of the mounting plate 1. The L-shaped connecting block 206 is rotatably connected to the outside of the fixed shaft 205, and the connecting shaft 207 is fixedly connected to the bottom surfaces of the two sides of the L-shaped connecting block 206.

[0025] As can be seen from the above working process, by setting up the mounting plate 1, the fixing mechanism 2 and the L-shaped mounting base 5, the L-shaped mounting base 5 facilitates connection with different external structural surfaces, expands the applicable scenarios of the lens, improves the versatility of the overall structure, and realizes a convenient and stable connection between the optical lens body 3 and the external structure.

[0026] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that there are four connecting rods 208. The two ends of the connecting rods 208 are rotatably connected to the outside of the two connecting shafts 207 respectively, and the connecting plate 204 is fixedly connected to the middle of the left connecting rod 208.

[0027] The left connecting rod 208 drives the L-shaped connecting block 206 connected to it to rotate around the fixed shaft 205 via the connecting shaft 207, and then drives all L-shaped connecting blocks 206 to rotate synchronously via other connecting rods 208.

[0028] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that there are four fixed plates 209, which are symmetrically fixedly connected to the four sides of the bottom surface of the mounting groove of the mounting plate 1. The movable column 210 passes through the fixed plate 209 and is slidably connected to the fixed plate 209. The side of the movable column 210 near the connecting rod 208 is set as an arc surface.

[0029] When the connecting rod 208 moves, it can squeeze and push the arc-shaped surface on one side of the moving column 210, thereby causing the moving column 210 to slide inside the fixed plate 209, improving the practicality of the mechanism.

[0030] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the optical lens body 3 has symmetrical mounting holes 4 around its upper perimeter that are adapted to the moving post 210.

[0031] The movable column 210 slides inside the fixed plate 209 toward the optical lens body 3, and finally the movable column 210 is inserted into the mounting hole 4 of the optical lens body 3, thus completing the fixation of the optical lens body 3.

[0032] The solution has the following working process: When in use, the optical lens body 3 is placed in the mounting groove of the mounting plate 1, ensuring that the mounting holes 4 on the upper periphery of the optical lens body 3 correspond to the positions of the moving posts 210 on the four sides of the bottom surface of the mounting groove.

[0033] When cylinder 202 is activated, its output end extends, causing rotating block 203 to move forward. Rotating block 203 pulls connecting plate 204, which in turn moves left connecting rod 208. Left connecting rod 208 drives L-shaped connecting block 206 connected to it to rotate around fixed shaft 205 via connecting shaft 207. This, in turn, drives all L-shaped connecting blocks 206 to rotate synchronously via other connecting rods 208. During the movement of connecting rod 208, it exerts a squeezing and pushing effect on the arc-shaped surface of moving column 210 near connecting rod 208, causing moving column 210 to slide towards optical lens body 3 inside fixed plate 209. Finally, moving column 210 is inserted into mounting hole 4 of optical lens body 3, completing the fixation of optical lens body 3.

[0034] The entire optical lens structure is connected and fixed to the external structural surface by the L-shaped mounting bases 5 symmetrically arranged above the mounting plate 1, thereby realizing the assembly of the lamp.

[0035] When it is necessary to disassemble or replace the optical lens body 3, the output end of the control cylinder 202 retracts, causing the rotating block 203, connecting plate 204 and connecting rod 208 to move in the opposite direction. The squeezing force of the connecting rod 208 on the moving column 210 disappears, and the moving column 210 can be manually or through the reset structure to be removed from the mounting hole 4. Then the optical lens body 3 can be taken out from the mounting slot.

[0036] In summary: By setting up the mounting plate 1, the fixing mechanism 2, and the L-shaped mounting base 5, the L-shaped mounting base 5 facilitates connection with different external structural surfaces, expanding the applicable scenarios of the lens and improving the versatility of the overall structure, thus achieving a convenient and stable connection between the optical lens body 3 and the external structure; the fixing mechanism 2, driven by the cylinder 202, drives the connecting rod 208 to rotate the L-shaped connecting block 206 around the fixed axis 205, thereby pushing the moving column 210 into the mounting hole 4 of the optical lens body 3, completing a quick fixation, which is simple and efficient to operate; during disassembly, only the cylinder needs to be reset, greatly improving the convenience of installation and disassembly.
