[0017] The present utility model will be further described below with reference to the drawings and embodiments.

[0018] Referring to Figures 1 - 5 , a positioning and assembling structure of an infrared laser lens includes a mounting housing 10 and a lens body 20. A light-transmitting groove 110 is provided on the front side of the mounting housing 10, the lens body 20 is disposed in the light-transmitting groove 110, positioning convex edges 210 are provided around the lens body 20, and the positioning convex edges 210 are fitted to the front inner wall of the mounting housing 10;

[0019] A metal elastic clamping element 30 for clamping and limiting with the mounting housing 10 is provided on each positioning convex edge 210.

[0020] The present utility model forms positioning by fitting the positioning convex edges to the front inner wall of the mounting housing. By using the metal elastic clamping element to be clamped with the mounting housing, the front and rear positions of the lens body and the mounting housing can be restricted. The metal elastic clamping element can avoid the problem that the existing injection-molded integral buckle is prone to breakage and cause the lens to be unusable, and has better stability.

[0021] Referring to Figure 4, a positioning portion 120 opposite to the positioning convex edge 210 is provided on the inner wall of the front side of the installation housing 10. A positioning groove 130 is provided on the wall surface of the positioning portion 120 facing the positioning convex edge 210, and the metal elastic clamping element 30 is clamped in the positioning groove 130. The cooperation between the metal elastic clamping element 30 and the positioning groove 130 can restrict the front-back movement of the lens body 20 relative to the installation housing 10, so as to achieve the function of clamping and limiting assembly.

[0022] See Figure 4 , the metal elastic clamping element 30 includes a connecting portion 310 connected to the positioning convex edge 210. An arc-shaped clamping portion 330 is provided at one end of the connecting portion 310 away from the positioning convex edge 210. The arc-shaped clamping portion 330 is clamped in the positioning groove 130, and a pressing portion 340 is provided at one end of the arc-shaped clamping portion 330 away from the connecting portion 310.

[0023] During installation, the lens body 20 is inserted and matched with the light-transmitting groove 110. During the process of inserting and assembling the lens body 20 from back to front, the mutual clamping portion 330 is pressed to cause the entire metal elastic clamping element 30 to deform until the arc-shaped space portion 330 is clamped into the positioning groove 130 to complete the assembly.

[0024] During disassembly, press the pressing portion 340 to cause the arc-shaped clamping portion 330 to deform, so that the arc-shaped clamping portion 330 disengages from the positioning groove 130. Thus, the pressing portion 340 can be held to drive the lens body 20 to move backward, and then the disassembly is completed.

[0025] See Figure 4 , a fixing portion 320 is provided at one end of the connecting portion 310 away from the arc-shaped clamping portion 330, and the fixing portion 320 is fixedly connected to the positioning convex edge 210.

[0026] Further, the fixing portion 320 is arranged in an L shape, and the fixing portion 320 and the positioning convex edge 210 are integrally formed by injection molding. When the lens body 20 is injection molded, the metal elastic clamping element 30 is placed in the mold to achieve integral injection molding.

[0027] Further, the lens body 20 is arranged in a square shape, and the positioning convex edges 210 are at least respectively arranged on two opposite sides of the lens body 20. That is, there are at least two positioning convex edges 210 and they are respectively arranged on the left and right sides or the upper and lower sides of the lens body.
