The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0021] Reference Figure 1-4 The utility model embodiment provides a lens structure, which includes: a frame 1, the left and right walls of the frame 1 are a split structure, and the left and right walls of the frame 1 are fixedly connected to a connecting rod 8 on one side close to the frame 1 body, and the end of the connecting rod 8 close to the center point of the frame 1 penetrates into the interior of the frame 1 body. The above devices cooperate with each other to form a stretching and disassembly structure, wherein the connecting rod 8 entering the interior of the frame 1 body is provided with a card block to prevent the left and right walls of the frame 1 from completely separating from the frame 1 body during the process of splitting the lens structure. The left and right walls of the frame 1 and the frame 1 body are respectively provided with a reinforcement rod 7 and a docking cavity 11. When assembling the lens structure, one end of the reinforcement rod 7 is located inside the docking cavity 11. The reinforcement rod 7 is an L-shaped structure, which improves the stability of the left and right walls of the frame 1 after they are combined.

[0022] The left and right surfaces of the frame 1 are both provided with storage slots 10, which are engaged with the other end of the reinforcement rod 7. The storage slots 10 are engaged with the reinforcement rod 7 to improve the stability of the reinforcement rod 7 when it is in effect and to prevent the reinforcement rod 7 from slipping off during the use of the lens structure. A plurality of screws 9 are threadedly connected to the bottom of the frame 1, and the upper ends of the screws 9 penetrate into the interior of the main body of the frame 1, and one end of the reinforcement rod 7 entering the docking cavity 11 is penetrated by the screws 9. The screws 9 further improve the stability of the reinforcement rod 7 when it is in effect. A plurality of storage grooves 13 are provided on the lower surface of the frame 1, and the lower ends of the screws 9 are located inside the storage grooves 13. The storage grooves 13 receive the portion of the screws 9 that has not entered the main body of the frame 1, thereby preventing the screws 9 from affecting the flatness of the bottom of the frame 1.

[0023] A light source base 2 and a convex mirror 3 are provided inside the frame 1. The light source base 2 is fixedly connected to the bottom wall of the frame 1, and the lower end of the light source base 2 passes through the lower surface of the frame 1. The light source base 2 includes a base for installing the light source and a cable tray required for threading the power cord, so as to improve the convenience of installing the lamp light source. A filling ring 12 is provided at the upper end of the frame 1. When the lens structure is assembled, the lower surface of the filling ring 12 is in close contact with the upper surface of the convex mirror 3. The filling ring 12 is made of rubber. The filling ring 12 squeezes and fills the gap between the upper surface of the convex mirror 3 and the frame 1, thereby improving the sealing effect of the convex mirror 3 after installation, and reducing the wear effect between the frame 1 and the convex mirror 3 under vibration.

[0024] The front, back, left and right inner walls of the frame 1 are respectively provided with rubber pads 5 and positioning slots 4. The rubber pads 5 are fixedly connected to the front and back inner walls of the frame 1. The rubber pads 5 are in close contact with the arc edge of the convex mirror 3. The positioning slots 4 are engaged with the flat edge of the convex mirror 3. The rubber pads 5 and the positioning slots 4 cooperate with each other to form a reinforcement structure for fixing the convex mirror 3 with a lens structure, wherein the rubber pads 5 are used to fix the side of the convex mirror 3 whose edge shape is too uneven, and the positioning slots 4 are used to fix the side of the convex mirror 3 whose edge shape is relatively flat. A profiling groove 6 is provided on the side of the rubber pad 5 close to the light source base 2, and the arc edge of the convex mirror 3 is located inside the profiling groove 6. The profiling groove 6 further improves the limiting effect of the rubber pad 5 on the too uneven side of the convex mirror 3, thereby improving the overall stability of the lens structure when in use.

[0025] Working principle: When assembling the lens structure, first install the light source above the light source base 2, then lead the power cord for powering the light source out of the frame 1 through the cable duct of the light source base 2, and then clamp the two sides of the convex mirror 3 used in the lens structure that are too uneven in shape in the inside of the profiling groove 6 by tilting the convex mirror 3 and manually pressing the rubber pad 5, and then push the left and right walls of the frame 1. In the process of the left and right ends of the frame 1 approaching the main body of the frame 1, the relatively flat sides of the convex mirror 3 are clamped with the positioning grooves 4 on the left and right walls of the frame 1. At this time, the left and right walls of the frame 1 are completely merged with the main body of the frame 1, and then push Reinforcement rod 7 is used to improve the merging stability of frame 1, and then screw 9 is used to fix reinforcement rod 7, and finally filling ring 12 is manually compressed to fill the gap between the upper surface of convex mirror 3 and frame 1 with filling ring 12, so as to further improve the sealing effect of lens structure, and finally the external power line is connected with the external power line, and the lamp made of this lens structure can be used. When maintaining the lens structure, the restriction of reinforcement rod 7 by contact screw 9 can directly stretch and separate the left and right walls of frame 1, and convex mirror 3 is restricted by rubber pad 5 and will not fall directly. At this time, the convex mirror 3 can be manually removed to directly carry out the maintenance work of the light source.
