[0001] The utility model relates to the technical field of headlights, in particular to a focusing headlight structure. Background Art

[0002] Headlamps are commonly used lighting tools in mines, tunnels, roads, construction sites and other outdoor work areas at night. Compared with flashlights, electric lights and other lighting tools, headlamps are more practical and convenient to carry. You don't need to use your hands during use, which is more convenient for lighting. When using headlamps, due to the actual needs, you need to adjust the focal length of the light emitted by the headlamp. Sometimes you need diffuse lighting, and sometimes you need concentrated lighting.

[0003] In view of this, in the current existing headlamp, the assembly work between the focusing tube and the housing is very complicated and the structure is relatively complex, resulting in very high assembly costs. Utility Model Content

[0027] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. Obviously, the described implementation is a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-7 The utility model provides a technical solution: a focusing headlight structure, comprising a housing 1 and a focusing tube 2, wherein the focusing tube 2 is sleeved on the housing 1, and the surface of the end of the housing 1 is rounded, which can effectively reduce the friction of the focusing tube 2 when sliding, and facilitate the movement of the focusing tube 2. The focusing tube 2 is slidably arranged on the housing 1, and the distance of the lens is controlled, thereby realizing the focusing function of the light;

[0029] In order to prevent the focusing tube 2 from falling off from the shell 1, a clamping block 3 is provided on the inner side of the focusing tube 2, and the clamping block 3 is installed on the inner wall of the focusing tube 2. In this way, the blocking of the clamping block 3 is utilized to effectively prevent the focusing tube 2 from falling off from the clamping block 3, and at least two clamping blocks 3 are provided to realize the coupling connection between the shell 1 and the focusing tube 2.

[0030] See also Figure 1-5 , a through groove corresponding to the card block 3 is provided at the end of the shell 1, and an integrally formed docking block 4, a spacer block 5 and a counter-block 6 are arranged inside the through groove, and the spacer block 5 is arranged between the docking block 4 and the counter-block 6. The docking block 4, the spacer block 5 and the counter-block 6 have different functions. Specifically, the top of the docking block 4 is smoothly wedge-shaped, and the angle between the side surface and the bottom surface is 45 degrees. In this way, when the focusing tube 2 is installed, by pressing the focusing tube 2, the card block 3 will move along the inclined surface of the docking block 4. Since the card block 3, the docking block 4, the spacer block 5 and the counter-block 6 are all made of elastic plastic, the focusing tube 2 and the shell 1 can be smoothly connected and installed;

[0031] When the card block 3 passes over the docking block 4, it will immediately pass over the docking block 4. When passing over the spacing block 5, the inclined surface of the card block 3 on one side close to the shell 1 is set with an angle corresponding to the docking block 4, which can ensure that the card block 3 passes over the docking block 4 smoothly. The left side of the card block 3 is vertically arranged with the focusing tube 2, and the right side of the anti-block 6 is vertically arranged with the shell 1. When the focusing tube 2 and the shell 1 are inserted into each other, the focusing tube 2 can be prevented from falling off the shell 1, and the angle between the anti-block 6 and the shell 1 is in a vertical state. Therefore, when the card block 3 passes over the anti-block 6, the installation of the focusing tube 2 is completed. Compared with the prior art, the assembly work of the focusing tube 2 is very simple and convenient, with low cost and high assembly efficiency. The assembly work between the focusing tube 2 and the shell 1 is very simple, the structure is relatively simple, and the assembly cost is very low.

[0032] See also Figure 1-7 , a plurality of groups of card slots 7 are provided at the end of the housing 1. Elastic rings 8 for damping the focusing tube 2 are embedded in the plurality of card slots 7. When the focusing tube 2 is focused, the friction between the elastic ring 8 and the focusing tube 2 can effectively position the focusing tube 2, and can prevent the focusing tube 2 and the housing 1 from being relatively stationary without external force.

[0033] See also Figure 1-7 A rectangular block 9 is symmetrically arranged inside the focusing tube 2 , and a rectangular groove 10 corresponding to the rectangular block 9 is arranged on the housing 1 .

[0034] In one embodiment of the utility model, the end portion of the shell 1 is conically arranged, and the inner wall of the focusing tube 2 is adapted to be used with the conical portion of the shell 1, so that the inner wall of the focusing tube 2 is always in contact with the elastic ring 8, thereby ensuring normal focusing work.

[0035] Specifically, the working process or working principle of the focusing headlamp structure is as follows: when the focusing tube 2 is installed, the control block 3 is made to correspond to the through groove, and then squeezed from one end of the focusing tube 2, and then the block 3 will pass over the docking block 4, and then pass over the elastic ring 8, and then pass over the spacing block 5, and finally pass over the anti-blocking block 6, until the assembly of the focusing tube 2 is completed;

[0036] When the lens is to be focused, the focusing tube 2 is pushed, and under the friction of the elastic ring 8, the distance between the lens and the end of the housing 1 is controlled by the thrust, so that the focusing of the lens can be completed.

[0037] It should be noted that for devices or equipment existing in the prior art, or devices or equipment that can be implemented in the prior art, their power supply, specific composition and principles are clear to those skilled in the art, so they are not described in detail.

[0038] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. 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.
