DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0021] This application discloses a push-to-release structure, referring to Figure 1-5 , including a shell 1 (which can be used as the shell of the battery box or the shell part of the lamp body) and a head-mounted bracket 2; a guide groove 12 with an open end is horizontally provided on the bottom wall of the shell 1, and limiting grooves 11 are symmetrically provided on the bottom wall of the shell 1 at both ends of the guide groove 12. The head-mounted bracket 2 includes a bracket body 21 and a buckle plate 26. The upper end of the bracket body 21 is provided with a guide boss 24 that fits and slides with the guide groove 12. The guide groove 12 and the guide boss 24 are both "T"-shaped. The cooperation between the guide groove 12 and the guide boss 24 can assist in limiting the installation position between the battery box or the lamp body and the head-mounted bracket 2, thereby ensuring the accuracy after the combination. At the same time, affected by the shapes of the guide groove 12 and the guide boss 24, the overall up and down and front and back positions can also be limited after the combination, thereby improving the strength after the combination.

[0022] It should be mentioned here that when the shell 1 is the outer shell of the battery box, a transmission line is also provided on one side of the shell 1 for connecting with the lamp body. After the lamp body is disassembled, the whole can also be used as a flashlight, thereby increasing the overall applicability of the headlamp. Secondly, the above push-on quick-release structure can also be used in other fields, which is not limited here.

[0023] Furthermore, limiting protrusions 261 adapted to be engaged with the limiting grooves 11 are provided on both sides of the upper end of the buckle plate 26, and an elastic member 20 is provided between the buckle plate 26 and the head-mounted bracket 2; when the buckle plate 26 is tilted upward by the elastic force of the elastic member 20, the limiting protrusion 261 is clamped in the limiting groove 11, and the locking operation is completed; when the buckle plate 26 moves downward under external pressure, the limiting protrusion 261 is disengaged from the limiting groove 11, and the unlocking operation is completed. The guide boss 24 is inserted into the limiting groove 12, and when the guide boss 24 is pushed to the end, the limiting protrusion 261 is correspondingly inserted into the limiting groove 11 to realize the locking operation of the shell 1 and the head-mounted bracket 2. When the shell 1 needs to be disassembled, the buckle plate 26 is pressed downward to drive the limiting protrusion 261 to disengage from the limiting groove 11. At this time, the shell 1 can be pulled out toward the opening direction to complete the disassembly. It can be operated with one hand, and there is no need to take the headlamp off the head during disassembly and assembly, so the shell 1 can be quickly disassembled.

[0024] The limiting protrusion 261 is in a wedge shape, so that the limiting protrusion can be inserted into the limiting groove 11 easily.

[0025] Furthermore, support plates 23 are formed on the upper wall of the head-mounted bracket 2 at both ends of the guide boss 24, and the opposite sides of the two support plates 23 are recessed inward to form a rotation groove 231. Rotation shafts 262 corresponding to the rotation grooves 231 are protruded at both ends of the buckle plate 26. The buckle plate 26 can be rotated upward and downward respectively relative to the bracket body 21 through the rotation shaft 262. Through the cooperation of the rotation shaft 262 and the rotation groove 231, the movement of the buckle plate 26 can be guided by an auxiliary function, so that the buckle plate 26 can only be rotated upward or downward, thereby realizing subsequent unlocking and locking operations.

[0026] The height of the support plate 23 must be such that when the head-mounted bracket 2 and the shell 1 are assembled, the end surface of the support plate 23 is in contact with the surface of the shell 1 .

[0027] Furthermore, a button 25 extending out of the bracket body 21 is provided at the right end of the buckle plate 26, and the outer end surface of the button 25 is provided with anti-slip grooves. The guide groove 12 is recessed upward toward one end of the button 25 to form a recessed position that satisfies the up and down movement of the button 25. The button 25 can facilitate the user to press the buckle plate 26, and the recessed position will not interfere with the up and down movement of the button 25.

[0028] Furthermore, the elastic member 20 is a spring, and spring circular grooves 27 for fixing the elastic member 20 are respectively provided on the opposite sides of the bracket body 21 and the buckle plate 26. The elastic force of the spring can provide power for the buckle plate 26 to rotate upward. At the same time, the spring can also serve as an auxiliary positioning part of the bracket body 21 and the buckle plate 26 to prevent the buckle plate 26 from self-flipping.

[0029] Furthermore, a hole is opened at the left end of the pinch plate 26 to allow one end of the guide boss 24 to extend therein, and the hole will not interfere with the up and down movement of the pinch plate 26 .

[0030] Furthermore, the overall shape of the bracket body 21 is an arc, which is substantially the same as the shape of the head and conforms to the ergonomic design, thereby improving the comfort of the bracket body 21 when worn on the head.

[0031] Furthermore, binding grooves 22 are vertically penetrated at both ends of the bracket body 21 , and the binding grooves 22 on both sides serve as connecting parts with elastic binding bands (not shown in the figure).

[0032] To summarize, a push-to-quick release structure is designed between the shell 1 and the head-mounted bracket 2. When the shell 1 needs to be disassembled, the button 25 is pressed downward, and the buckle plate 26 moves downward to drive the limiting protrusion 261 to disengage from the limiting groove 11. At this time, the shell 1 can be pulled out toward the opening direction to complete the disassembly. When the shell 1 is replaced alone, the structure is simple and can be operated with one hand. There is no need to take the headlamp off the head during disassembly and assembly. The operation is more convenient and the overall quick release operation can be achieved.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
