Technical Field
[0001] This utility model belongs to the field of safety helmet technology, specifically, it relates to a safety helmet with a mining lamp angle adjustment device. Background Technology
[0002] Mining lamps mounted on safety helmets provide illumination while ensuring safety, making them particularly suitable for use in poorly lit environments such as mines. However, most current mining lamps are fixed to the helmet and only illuminate directly in front. Given the insufficient lighting in mines, simply illuminating the front is insufficient for practical needs. For example, they cannot illuminate the path when the user is walking, nor can they illuminate the notebook when the user is recording. An angle-adjustable mining lamp would effectively solve these problems. However, existing adjustable-angle mining lamps are difficult to adjust, often requiring both hands simultaneously, and the operation is time-consuming. Underground workers typically carry tools, making it difficult to use both hands simultaneously. Furthermore, underground work carries high safety risks, making it crucial to improve work efficiency in case of emergencies. Therefore, providing a technology that allows for quick and convenient angle adjustment of mining lamps is of significant importance for improving the safety and convenience of underground operations.

Detailed Implementation
[0021] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.
[0022] In the description of this utility model, unless otherwise stated, the terms "left", "right", "up", "down", etc., indicate the orientation or state relationship based on the orientation or state relationship shown in the drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "equipped with" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art will understand the specific meaning of the above terms in this invention according to the specific circumstances. Example 1
[0024] like Figure 1 , 2 As shown in Figure 5, the safety helmet with a miner's lamp angle adjustment device includes a helmet body 1, a miner's lamp 2, and a miner's lamp angle adjustment assembly 3. The miner's lamp angle adjustment assembly 3 is connected to the helmet body 1, and the miner's lamp 2 is connected to the miner's lamp angle adjustment assembly 3. The angle of the miner's lamp 2 is adjusted by the miner's lamp angle adjustment assembly 3 to meet different lighting needs (as shown in Figure 5). Figure 6 ).
[0025] The mine lamp adjustment assembly 3 includes a base 4, a left clamping rod 5, a right clamping rod 6, an adjustment shaft, a bushing A7, a bushing B8, a handle 9, and a mine lamp connector. The base 4 is block-shaped and is fixed to the front side of the safety helmet body 1 by screws, etc. (as shown in the attached diagram). Figure 6The left clamp 5 and right clamp 6 are opposite to each other and fixed on the side of the base 4 away from the safety helmet body 1. The left clamp 5, right clamp 6 and base 4 form a U-shaped opening. The bushing A7 is sleeve-shaped and is rotatably set between the left clamp 5 and right clamp 6 through the adjusting shaft. The bushing A7 rotates in the U-shaped opening through the adjusting shaft. The mine lamp connector is fixedly connected to the bushing A7. The rotation of the bushing A7 realizes the rotation of the mine lamp connector, thereby realizing the angle adjustment of the mine lamp 2.
[0026] Two bushings B8 are provided, and they share an eccentric wheel 10. One end of the adjusting shaft of bushing A7 is fixedly connected to the inner side of the left clamping rod 5, and the other end passes through the right clamping rod 5. A connecting plate 11 is provided on the side of the adjusting shaft that passes through the right clamping rod. An eccentric shaft through hole is opened on the connecting plate 11, and the eccentric shaft 10 passes through the eccentric shaft through hole. The two bushings B8 are respectively set on both sides of the connecting plate 11 through the eccentric shaft 10. Since the eccentric shaft 10 passes through the eccentric shaft through hole on the adjusting shaft, and the outer side of the bushing B8 is always in contact with the outer side of the right clamping rod 6, the distance between the eccentric shaft and the outer side of the right clamping rod 6 changes when the bushing B8 rotates. When the eccentric shaft 10 is at its farthest point from the outer side of the bushing B8 and contacts the outer side of the right clamping rod 6, the distance between the eccentric shaft 10 and the right clamping rod 6 is the largest, and the distance between the left clamping rod 5 and the right clamping rod 6 is the smallest, which can clamp and lock the rotating shaft A7. In other positions, the distance between the left clamping rod 5 and the right clamping rod 6 becomes larger, and the rotating shaft A7 can rotate between the left clamping rod 5 and the right clamping rod 6, allowing for the angle adjustment of the mine lamp 2. The outer side of the bushing B8 is designed as an equilateral prism structure. When locking the rotating shaft A7, the outer side of the bushing B8 and the right clamping rod 6 are in surface contact, thus preventing the bushing B8 from rotating after the bushing A7 is locked, which would affect the locking firmness of the bushing A7. Meanwhile, the number of edges of bushing B8 should be at least 6, and preferably 12-16. This ensures that: 1) bushing A7 is securely locked; 2) the adjustment resistance is small when adjusting the angle of the miner's lamp 2; and 3) the maximum design gap between the rotating shaft 7 and the left clamping rod 5 and the right clamping rod 6 is reduced, which is more conducive to locking the rotating shaft 7 after the miner's lamp angle adjustment is completed.
[0027] The mine lamp connector includes a connecting rod 12 and a fixing plate 13. The connecting rod 12 is fixedly connected to the bushing A7. The fixing plate 13 is perpendicular to the connecting rod 12 and fixedly connected to the end of the connecting rod away from the bushing A. The mine lamp 2 is fixedly connected to the fixing plate 13 by bolts or the like. The handle 9 is fixed to the outer side of the bushing B8. By rotating the handle 9, the bushing B8 is rotated, which in turn causes the mine lamp connector to rotate, thereby adjusting the angle of the mine lamp 2.
[0028] The handle 9 is fixedly connected to the two bushings B8 respectively, and the two bushings B8 are operated to rotate synchronously.
[0029] The structure of this utility model allows for angle adjustment of the miner's lamp 2 simply by rotating the bushing B8, making operation simple and labor-saving. With practice, it can be operated with one hand, for example, by using the index finger and thumb to operate the handle 9 while the other fingers provide slight support for the miner's lamp 2. Example 2
[0030] As attached Figure 1 , 3 As shown in Figure 6, the difference between this embodiment and Embodiment 1 is that the shape of the bushing B8 is different, while the rest is the same as in Embodiment 1. This embodiment mainly describes the structure of the bushing B8.
[0031] Bushing B8 has a planar section only at the farthest point from the outer edge of the eccentric shaft 10; the rest remains an arc surface (as shown in the attached diagram). Figure 3 The angle adjustment operation of the mine lamp 2 is the same as in Example 1. When locking the bushing A7, the flat section of the bushing B8 is in contact with the surface of the right clamping rod 6.
[0032] Compared to Embodiment 1, this structure allows the user to feel whether the sleeve is locked in place when rotating the sleeve B8 to lock the sleeve A7, and when rotating to the corner of the arc surface and the flat section. It is easier to judge whether the sleeve A7 has been rotated to the locking position by feel, which is more conducive to locking after the angle of the miner's lamp is adjusted. Example 3
[0033] The difference between this embodiment and Embodiments 1 and 2 lies in the structure of bushing A7. This embodiment mainly describes the structure of bushing A7.
[0034] As attached Figures 4 to 6 As shown, the bushing A7 includes two fixed sleeves 71 and one rotating sleeve 72. The two fixed sleeves 71 are respectively fixed to the inner sides of the left clamping rod 5 and the right clamping rod 6. The rotating sleeve 72 is disposed between the two fixed sleeves 71, and the opposite surfaces of the rotating sleeve 72 and the fixed sleeves 71 are respectively provided with teeth. The connecting rod 12 is fixedly connected to the rotating sleeve 72.
[0035] In this embodiment, teeth are provided on the opposing surfaces of the rotating sleeve 72 and the fixed sleeve 71. The frictional force between the rotating sleeve 72 and the fixed sleeve 71 is increased by the meshing of the teeth. When adjusting the angle of the mine lamp 2, the rotation speed of the rotating sleeve 72 can be controlled; when locking, the locking firmness of the rotating sleeve 72 can be increased.
[0036] The bushing B8 in this embodiment can use the structure of Embodiment 1, or the bushing B8 can be made without an edge (see attached). Figure 5When adjusting the angle, the meshing force of the teeth is used to lock the rotating sleeve 72. The bushing B8 structure of Embodiments 1 and 2 can also be used, but this requires higher machining accuracy. That is, when locking the bushing A7, it is necessary to ensure that the teeth of the rotating sleeve 72 and the fixed sleeve 71 are in the state of minimum gap. This places precision requirements on the number of teeth, the tooth pitch, the length of the adjusting shaft, the size of the bushing B8, and the design of the eccentric shaft 10.
[0037] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
