Description

Technical Field

[0001] The present invention belongs to the technical field of headlamps, and particularly relates to a headlamp with a multi-interface power supply function. Background Art

[0002] A headlamp is used to irradiate the surrounding environment in a working environment with insufficient light, so as to facilitate the staff to work in this working environment, and it can also be worn on the head of the staff to free the hands of the staff. It is particularly suitable for applications in places such as equipment maintenance, freight handling, skylight operation, line rush repair, field camping, and surgical medical treatment, and a headlamp with a multi-interface power supply function is required.

[0003] Currently, the Chinese patent with the publication number CN216158862U discloses a headlamp with a multi-interface power supply function, which relates to the technical field of land surveying and mapping tools, including: a body; a first fixed seat located at one end of the body; a rotating mechanism including a lamp holder, a fixed disk, and a first fixed block. The present invention realizes the function of adjusting the angle of the lamp holder by setting a rotating mechanism. Pull the moving rod, while the moving rod moves, it squeezes the first spring, the first spring retracts, the moving rod drives the first fixed block to move, the first fixed block separates from the fixed disk, and the first fixed block loses the state of clamping the fixed disk. At this time, the angle of the lamp holder can be adjusted by rotating the lamp holder. When the lamp holder is adjusted to the appropriate angle, stop pulling the moving rod, the first spring rebounds, the first fixed block contacts the fixed disk and maintains the clamping state of the fixed disk, thereby realizing the function of adjusting the angle of the lamp holder.

[0004] However, when the above device is in use, the first fixed block is fixed by the deformation of the first spring. As the use time increases, the deformation performance of the spring weakens, making it difficult to adjust the angle. Summary of the Invention

[0005] The purpose of the present invention is to solve the drawbacks existing in the prior art, and to propose a headlamp with a multi-interface power supply function. Its advantages are: the effect of long-term and effective angle adjustment can be achieved.

[0006] In order to achieve the above purpose, the present invention adopts the following technical scheme:

[0007] A headlamp with a multi-interface power supply function includes a body. A base is rotatably connected between the inner walls on both sides of the body through a rotating shaft. A lamp socket is provided at one end of the base. A rotating disk is fixedly connected to one side of the rotating shaft. A number of uniformly distributed limiting openings are formed at the edge of the rotating disk. A limiting rod is hinged to the top of one side of the body, and a sliding fit is formed between the limiting rod and the inner wall of the limiting opening.

[0008] Through the above technical solution: When in use, rotate the limit rod and separate the limit rod from the inner wall of the limit port, and then rotate the rotating disc. When the rotating disc rotates, the rotating shaft can be rotated, and the rotation of the rotating shaft can cause the base to rotate, so that the angle of the base can be adjusted. The angle adjustment of the base can make the angle of the lamp socket adjustable. Rotating the rotating block can make the threaded rod rotate, and the rotation of the threaded rod can make the slider slide on the inner wall of the slide rail, so that the height of the lamp socket can be adjusted, and the light of the lamp can better meet people's use. Therefore, the effect of long-term and effective angle adjustment can be achieved.

[0009] The present invention is further provided that a same limit spring is fixedly connected between the opposite side of the limit rod and the body.

[0010] Through the above technical solution: The setting of the limit spring can apply a pulling force to the limit rod, so that the limit rod can be stably placed in the limit port.

[0011] The present invention is further provided that the inner walls at both ends of the limit port are fixedly connected with limit pads, and the limit pads are made of rubber material.

[0012] Through the above technical solution: The setting of the limit pads can increase the friction between the inner wall of the limit port and the limit rod, so that the limit rod can be stably placed.

[0013] The present invention is further provided that a slide rail is fixedly connected to one side of the base, and a slider is slidably connected to the inner wall of the slide rail, and the slider is fixedly connected to the lamp socket.

[0014] Through the above technical solution: The setting of the slider can slide on the inner wall of the slide rail, so that the height of the lamp socket can be adjusted.

[0015] The present invention is further provided that a same threaded rod is rotatably connected between the top inner wall and the bottom of the slide rail through a bearing, and the threaded rod is threadedly connected to the slider.

[0016] Through the above technical solution: The setting of the threaded rod can make the slider perform a sliding operation when rotating.

[0017] The present invention is further provided that the top of the threaded rod is fixedly connected with a rotating block, and one side of the top of the rotating block is rotatably connected with a turning handle through a bearing.

[0018] Through the above technical solution: The setting of the rotating block can facilitate the staff to rotate the threaded rod.

[0019] The present invention is further provided that a lampshade is arranged on one side of the lamp socket.

[0020] Through the above technical solution: The setting of the lampshade can protect the lamp.

[0021] The present invention is further configured such that a connecting ring is fixedly connected to one side of the lamp shade, and a connecting groove for threaded connection with the connecting ring is provided on one side of the lamp socket.

[0022] Through the above technical solution: The setting of the connecting ring can rotate in the inner wall of the connecting groove, enabling the lamp shade to be separated from the lamp socket and facilitating the disassembly of the lamp bulb.

[0023] The present invention is further configured such that an upper cover is hinged to the top of one side of the lamp shade, a lower cover is hinged to the bottom of one side of the lamp shade, an upper rod is hinged to the bottom of the upper cover, a lower rod is hinged to the top of the lower cover, and the opposite sides of the upper rod and the lower rod are hinged to the same adjusting block.

[0024] Through the above technical solution: The setting of the adjusting block can apply forces to the upper rod and the lower rod respectively when moving in the horizontal direction. At this time, the angles between the lower rod and the upper rod and the adjusting block will change. The rotation of the upper rod and the lower rod can cause the upper cover and the lower cover to rotate around the connection with the lamp shade, thereby changing the angle between the upper cover and the lower cover. When the angle between them increases, the illumination range of the lamp bulb can be increased, enabling more areas to be illuminated. When it is necessary to concentrate the light, the distance between the upper cover and the lower cover can be reduced, making the light irradiation more concentrated.

[0025] The present invention is further configured such that an adjusting opening is provided on one side of the adjusting block, and an adjusting rod is threadedly connected to the inner wall of the adjusting opening. The adjusting rod is rotatably connected to the lamp shade through a bearing.

[0026] Through the above technical solution: The setting of the adjusting rod can rotate in the inner wall of the adjusting opening. The rotation of the adjusting rod can apply a force to the adjusting block. Since the adjusting block is limited by the upper rod and the lower rod, it can move as the adjusting rod rotates. The movement of the adjusting block can change the angle between the upper cover and the lower cover.

[0027] The present invention is further configured such that positioning rods are fixedly connected to the opposite sides of the upper cover and the lower cover, and the positioning rods are in an L-shaped structure.

[0028] Through the above technical solution: The L-shaped design can facilitate the horizontal ends of the positioning rods to limit the movement of the upper rod and the lower rod, prevent the upper rod and the lower rod from bending, and prevent the upper cover, the lower cover, and the lamp shade from getting stuck.

[0029] The present invention is further configured such that a positioning groove is provided on one side of the positioning rod, a positioning spring is fixedly connected to one inner wall of the positioning groove, one end of the positioning spring is fixedly connected to a positioning plate that forms a sliding fit with the inner wall of the positioning groove, and the positioning plate is in contact with the upper rod and the lower rod.

[0030] Through the above technical solutions: The positioning plate is provided and can slide in the inner wall of the positioning groove. At this time, the positioning spring is compressed, and the compression of the positioning spring can make the positioning plate in close contact with the upper rod or the lower rod, so that after the angle between the upper cover and the lower cover is adjusted, the angle between them is fixed.

[0031] The beneficial effects of the present invention are as follows:

[0032] 1. When using the headlamp with multi-interface power supply function, rotate the limit rod to separate it from the inner wall of the limit port, and then rotate the rotating disc. When the rotating disc rotates, the rotating shaft can be rotated, and the rotation of the rotating shaft can make the base rotate, so as to adjust the angle of the base. The angle adjustment of the base can make the angle of the lamp socket adjustable. Rotating the rotating block can make the threaded rod rotate, and the rotation of the threaded rod can make the slider slide in the inner wall of the slide rail, so as to adjust the height of the lamp socket, making the light of the lamp more suitable for people's use. By the adjusting rod, it can rotate in the inner wall of the adjusting port, and the rotation of the adjusting rod can apply force to the adjusting block. Since the adjusting block is limited by the upper rod and the lower rod, it can move as the adjusting rod rotates. The movement of the adjusting block can change the angle between the upper cover and the lower cover. Therefore, the effect of long-term and effective angle adjustment can be achieved.

[0033] 2. For the headlamp with multi-interface power supply function, the height of the lamp socket can be adjusted by the slider sliding in the inner wall of the slide rail; the slider can slide when the threaded rod rotates; the rotating block is convenient for the staff to rotate the threaded rod; the lamp shade can protect the lamp.

[0034] 3. For the headlamp with multi-interface power supply function, when the adjusting block moves horizontally, it can apply force to the upper rod and the lower rod respectively. At this time, the angles between the lower rod and the upper rod and the adjusting block will change. The rotation of the upper rod and the lower rod can make the upper cover and the lower cover rotate around the connection part with the lamp shade, that is, the angle between the upper cover and the lower cover can be changed. When the angle between them increases, the illumination range of the lamp can be increased, making more areas illuminated. When it is necessary to make the light concentrated, the distance between the upper cover and the lower cover can be reduced, making the light irradiation more concentrated.

For those of ordinary skill in the art, the specific meanings of the above terms in this patent can be understood according to specific circumstances.

[0047] Referring to Figure 1-3 , a headlamp with multi-interface power supply function, includes a body 1. A base 2 is rotatably connected between the inner walls on both sides of the body 1 through a rotating shaft. A lamp socket 3 is arranged at one end of the base 2. A rotating disk 4 is fixedly connected to one side of the rotating shaft. A number of uniformly distributed limiting ports 5 are formed at the edge of the rotating disk 4. A limiting rod 6 is hinged to the top of one side of the body 1. A sliding fit is formed between the limiting rod 6 and the inner wall of the limiting port 5.

[0048] It should be noted that in this embodiment, a same limiting spring 7 is fixedly connected between the limiting rod 6 and the opposite side of the body 1. The limiting spring 7 can apply a pulling force to the limiting rod 6, so that the limiting rod 6 can be stably placed in the limiting port 5.

[0049] It should be noted that in this embodiment, limiting pads 8 are fixedly connected to the inner walls at both ends of the limiting port 5, and the limiting pads 8 are made of rubber. The limiting pads 8 can increase the friction between the inner wall of the limiting port 5 and the limiting rod 6, so that the limiting rod 6 can be stably placed.

[0050] In one specific embodiment, a slide rail 9 is fixedly connected to one side of the base 2. A slider 10 is slidably connected to the inner wall of the slide rail 9. The slider 10 is fixedly connected to the lamp socket 3. The slider 10 can slide in the inner wall of the slide rail 9, so that the height of the lamp socket 3 can be adjusted.

[0051] It should be noted that in this embodiment, a same threaded rod 11 is rotatably connected between the top inner wall and the bottom of the slide rail 9 through a bearing. The threaded rod 11 is threadedly connected to the slider 10. When the threaded rod 11 rotates, the slider 10 can be slid.

[0052] Furthermore, in this embodiment, a rotating block 12 is fixedly connected to the top of the threaded rod 11. One side of the top of the rotating block 12 is rotatably connected to a turning handle through a bearing. The rotating block 12 can facilitate the staff to rotate the threaded rod 11.

[0053] A lamp cover 13 is arranged on one side of the lamp socket 3. The lamp cover 13 can protect the lamp.

[0054] One side of the lampshade 13 is fixedly connected with a connecting ring 15. A connecting groove 14 which is threadedly connected with the connecting ring 15 is formed on one side of the lamp socket 3. The connecting ring 15 can rotate in the inner wall of the connecting groove 14, so that the lampshade 13 can be separated from the lamp socket 3, which is convenient for disassembling the lamp bulb.

[0055] In one specific embodiment, an upper cover 16 is hinged to the top of one side of the lampshade 13, and a lower cover 17 is hinged to the bottom of one side of the lampshade 13. A upper rod 18 is hinged to the bottom of the upper cover 16, and a lower rod 19 is hinged to the top of the lower cover 17. The opposite sides of the upper rod 18 and the lower rod 19 are hinged with the same adjusting block 20. When the adjusting block 20 moves horizontally, it can apply forces to the upper rod 18 and the lower rod 19 respectively. At this time, the angles between the lower rod 18 and the upper rod 19 and the adjusting block 20 will change. The rotation of the upper rod 18 and the lower rod 19 can make the upper cover 16 and the lower cover 17 rotate around the connection part with the lampshade 13, that is, the angle between the upper cover 16 and the lower cover 17 can be changed. When the angle between them increases, the illumination range of the lamp bulb can be increased, so that more areas can be illuminated. When it is necessary to make the light concentrated, the distance between the upper cover 16 and the lower cover 17 can be reduced, so that the light irradiation can be more concentrated.

[0056] In one specific embodiment, an adjusting opening 21 is formed on one side of the adjusting block 20. An adjusting rod 23 is threadedly connected to the inner wall of the adjusting opening 21. The adjusting rod 23 is rotatably connected to the lampshade 13 through a bearing. The adjusting rod 23 can rotate in the inner wall of the adjusting opening 21. The rotation of the adjusting rod 23 can apply a force to the adjusting block 20. Since the adjusting block 20 is limited by the upper rod 18 and the lower rod 19, it can move as the adjusting rod 23 rotates. The movement of the adjusting block 20 can change the angle between the upper cover 16 and the lower cover 17.

[0057] It should be noted that in this embodiment, positioning rods 24 are fixedly connected to the opposite sides of the upper cover 16 and the lower cover 17. The positioning rods 24 are in an L-shaped structure. The horizontal ends of the L-shaped positioning rods 24 can facilitate the limitation of the movement of the upper rod 18 and the lower rod 19, which can prevent the upper rod 18 and the lower rod 19 from being bent and prevent the upper cover 16, the lower cover 17 and the lampshade 13 from being stuck.

[0058] Furthermore, in this embodiment, a positioning groove 25 is formed on one side of the positioning rod 24. A positioning spring 26 is fixedly connected to the inner wall on one side of the positioning groove 25. One end of the positioning spring 26 is fixedly connected to a positioning plate 27 that forms a sliding fit with the inner wall of the positioning groove 25. The positioning plate 27 is in contact with the upper rod 18 and the lower rod 19. The positioning plate 27 can slide in the inner wall of the positioning groove 25. At this time, the positioning spring 26 is compressed. The compression of the positioning spring 26 can make the contact between the positioning plate 27 and the upper rod 18 or the lower rod 19 tight. After the angle between the upper cover 16 and the lower cover 17 is adjusted, the angle between them can be fixed.

[0059] Working principle: When in use, rotate the limit rod 6 to separate the limit rod 6 from the inner wall of the limit port 5, and then rotate the rotating disk 4. When the rotating disk 4 rotates, the rotating shaft can be rotated. The rotation of the rotating shaft can make the base 2 rotate, and the angle of the base 2 can be adjusted. The angle adjustment of the base 2 can make the angle of the lamp socket 3 adjusted. Rotating the rotating block 12 can make the threaded rod 11 rotate. The rotation of the threaded rod 11 can make the slider 10 slide in the inner wall of the slide rail 9, and the height of the lamp socket 3 can be adjusted, so that the light of the lamp can better meet people's use. The adjusting rod 23 can rotate in the inner wall of the adjusting port 21. The rotation of the adjusting rod 23 can apply a force to the adjusting block 20. Since the adjusting block 20 is restricted by the upper rod 18 and the lower rod 19, it can move as the adjusting rod 23 rotates. When the adjusting block 20 can move in the horizontal direction, forces are respectively applied to the upper rod 18 and the lower rod 19. At this time, the angles between the lower rod 18, the upper rod 19 and the adjusting block 20 will change, and then the angle between the upper cover 16 and the lower cover 17 can be changed. When the angle between them increases, the illumination range of the lamp can be increased, and more areas can be illuminated. When it is necessary to make the light concentrated, the distance between the upper cover 16 and the lower cover 17 can be reduced, and then the irradiation of the light can be made more concentrated. Therefore, the effect of long-term and effective angle adjustment can be achieved.

[0060] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
