DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0028] Please refer to Figures 1-5 In the embodiments of the present application, the improved high-heat-dissipation small head lamp with adjustable lamp head structure comprises a fixed clamp 10, a head wearing ring 20 connected to the fixed clamp 10, and a lamp head 30 detachably assembled on the fixed clamp 10. The fixed clamp 10 has arc-shaped clamps 11 formed forward on both sides. The lamp head 30 has a horizontally arranged cylindrical main body 31, a power supply unit 32 integrated in the cylindrical main body 31, a lamp barrel part 33 formed at the middle position of the front side of the cylindrical main body 31, a light source plate 34 installed in the lamp barrel part 33 and electrically connected to the power supply unit 32, and a light transmission ring 35 fixed to the end of the lamp barrel part 33. The cylindrical main body 31 is made of metal material and has certain heat conduction efficiency. The light source plate 34 generates light source by power supply of the power supply unit 32. The power supply unit 32 adopts conventional technical means and has a battery, a power board, a control switch, a charging interface, etc. The battery is connected to the light source plate 34 through the power board and the control switch to form a discharge circuit, and the battery forms a charging circuit through the power board and the charging interface, so that the high-heat-dissipation small head lamp completes the basic functions of light emission and energy storage. The application will not be described in detail. After being used for a period of time, the heat is conducted to the outside through the cylindrical main body 31 itself to complete the dissipation of heat.

[0029] The application is based on the above prior art, and the annular clamping groove 311 is formed around the cylindrical body 31 on both sides of the lamp barrel part 33, the fixing clamp 10 and the lamp holder 30 are detachably assembled through the clamping and matching of the optimal arc-shaped hoop 11 and the annular clamping groove 311, and the lamp holder 30 can rotate along the optimal arc-shaped hoop 11; the optimal arc-shaped hoop 11 is clamped into the annular clamping groove 311 through the elastic deformation of itself, so that the cylindrical body 31 and the fixing clamp 10 are connected, and the fixing clamp 10 is fixed on the head-wearing ring 20, which is used for wearing on the head of the user, so that the lamp holder 30 can be fixed on the forehead of the user after being connected and worn; wherein the annular clamping groove 311 and the optimal arc-shaped hoop 11 are a damping matching structure, a plurality of evenly distributed gear grooves 312 are arranged on the annular clamping groove 311, the inside of the optimal arc-shaped hoop 11 is provided with at least one gear block 12 matched with the gear groove 312, and the lamp holder 30 is adjustably positioned on the optimal arc-shaped hoop 11 through the clamping and matching of the gear block 12 and the different gear grooves 312. The clamping design of the gear groove 312 and the gear block 12 can provide a multi-gear positioning function on the basis of traditional damping matching, avoid the angle slip of the lamp holder 30 caused by shaking, and the user does not need to manually adjust frequently, thereby improving the use convenience and lighting reliability. In the technical solution, as shown in Figure 1 the inside of the optimal arc-shaped hoop 11 is provided with three gear blocks 12, and at least seven gear grooves 312 are arranged on the annular clamping groove 311, so that the optimal arc-shaped hoop 11 and the annular clamping groove 311 have a plurality of limiting points, thereby improving the firmness and stability of the positioning matching therebetween. In normal use, the three gear blocks 12 are clamped into the middle three gear grooves 312, so that the structure has at least two gear grooves 312 above and below, thereby enabling the user to adjust the rotation of at least two gears from above or below. In the setting of the rotation angle, the included angle between the adjacent two gear blocks 12 or the adjacent two gear grooves 312 to the axis of the cylindrical body 31 is 10°, that is, the cylindrical body 31 has an angle adjustment of at least 40°, which can almost meet the adaptability of the angle of the lamp holder 30 for different height populations, and the universality and personalized adaptation are considered.

[0030] The limiting part 313 corresponding to the annular clamping groove 311 is also formed on the front side of the cylindrical body 31 corresponding to the positions on both sides of the lamp barrel part 33, the optimal arc-shaped hoop 11 and the cylindrical body 31 are limited in rotation through the limiting part 313, and the heat dissipation fins 314 are formed on the limiting part 313.

[0031] By forming the limiting portion 313 on the cylindrical body 31 and setting the heat dissipation fins 314 on the limiting portion 313, and setting them on both sides of the lamp barrel portion 33, a heat dissipation structure acting on the light source plate 34 is formed, which can effectively reduce the temperature of the lamp head 30 and avoid the discomfort caused by heat concentration. In addition, the two sides of the lamp barrel portion 33 and the cylindrical body 31 are arc transition structures, the limiting portion 313 is integrally connected to the arc transition structure, and the end of the limiting portion 313 is flush with the end of the lamp barrel portion 33. The arc transition structure eliminates the stress concentration point of the traditional right-angle connection, enhances the overall strength of the lamp head 30, and makes the airflow flow smoothly along the arc surface. The heat dissipation fins 314 of the limiting portion 313 further improve the air convection efficiency and strengthen the heat dissipation effect. The flush design of the end makes the front end profile of the lamp head 30 more regular, which reduces the risk of hooking clothes or hair when wearing and improves the safety of use, and facilitates the user to hold or place the lamp head 30, enhancing the operation convenience.

[0032] In addition, in addition to the heat dissipation effect, the limiting portion 313 also has a limiting function. When the lamp head 30 rotates too much, the two ends of the arc-shaped hoop 11 abut against the limiting portion 313 to limit the rotation of the cylindrical body 31, which ingeniously combines heat dissipation and limiting, and makes the overall structure more compact while still having high heat dissipation effect.

[0033] Please refer to Figures 3-5 On the basis of the above technical scheme, it is further proposed that the two ends of the arc-shaped hoop 11 are bent and extended with a bent portion 13, which has the effect of guiding the expansion of the arc-shaped hoop 11. When assembling the lamp head 30, the bent portion 13 abuts against the annular clamping groove 311, so that the arc-shaped hoop 11 expands under the guidance of the bent portion 13 and is clamped into the annular clamping groove 311. The bent portion 13 is matched with the side of the limiting portion 313, which has a certain elasticity and can buffer to a certain extent when the lamp head 30 rotates too much and the bent portion 13 abuts against the limiting portion 313.

[0034] Please refer to Figure 2 , Figure 4 and Figure 5 On the basis of the above technical scheme, it is further proposed that the fixing clamp 10 further includes an open downward clamping portion 14 and a transition portion 15 formed on both sides of the clamping portion 14. The arc-shaped hoop 11 is formed by extending the end of the transition portion 15 forward, and the clamping portion 14 is used to clamp the head wearing ring 20. The transition portion 15 is a special-shaped bent structure, and the clamping portion 14 is spaced apart from the cylindrical body 31 through the transition portion 15, so that the cylindrical body 31 can be isolated from the head to a certain extent when worn.

[0035] It is apparent for a person skilled in the art that the present application is not limited to the details of the above-described exemplary embodiments, but that it can be implemented in other concrete forms without departing from the spirit or the essential characteristics of the present application. Therefore, the embodiments should be considered as exemplary only, and are non-limiting, the scope of the present application being defined by the appended claims rather than by the above description, and all changes coming within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
