[0034] Figures 1 to 10 It is a schematic diagram of a certain implementation mode of a push button mechanism of the utility model.

[0035] Reference Figures 1 to 10 , and mainly refer to Figure 2 , Figure 3 and Figure 4 According to the present embodiment, a push button mechanism (for the sake of convenience, it is sometimes referred to as a "push button mechanism" below). The push button mechanism of the present embodiment includes a flash housing 100, a movable slider 200 and a push button 300. In the present embodiment, a receiving chamber 110 is provided inside the flash housing 100. An opening for the entry and exit of parts is provided at one end of the receiving chamber 110. A control circuit board 120 is fixedly installed inside the receiving chamber 110. The control circuit board 120 is electrically connected to a shift switch 130. Specifically, the shift switch 130 is integrally welded to the upper surface of the substrate of the control circuit board 120. The shift switch 130 is electrically connected to the circuit of the control circuit board 120 through two conductive pins. A strip-shaped through slot 101 is provided at a position of the side wall of the flash housing 100 corresponding to the shift switch 130. The movable slider 200 is movably installed inside the accommodating chamber 110. The movable slider 200 is transmission-connected to the shift switch 130. The movable slider 200 can abut against the inner wall of the accommodating chamber 110 and limit the movable slider 200 from passing through the bar through slot 101 to move to the outside of the accommodating chamber 110. Specifically, the length of the movable slider 200 is greater than the length of the bar through slot 101. Therefore, when the movable slider 200 is tightly attached to the inner wall of the accommodating chamber 110 and moves along the length direction of the bar through slot 101, one end or both ends of the movable slider 200 abut against the accommodating chamber 110, ensuring that the movable slider 200 cannot pass through the bar through slot 101 to move to the outside of the accommodating chamber 110. The push button 300 is movably installed inside the strip slot 101, one end of the push button 300 is detachably connected to the movable slider 200, and the other end of the push button 300 is at least partially located outside the strip slot 101, wherein when the push button 300 is pushed to move along the strip slot 101, the push button 300 can drive the shift switch 130 to turn on or off by moving the movable slider 200.

[0036] The push button mechanism of this embodiment is provided with a movable slider 200 movably installed inside the accommodating chamber 110, and the movable slider 200 is transmission-connected to the toggle switch 130, and the movable slider 200 is detachably connected to one end of the push button 300. Therefore, when the user pushes the push button 300 to move along the bar through slot 101, the push button 300 can drive the toggle switch 130 to turn on or off through the movable slider 200, which not only can achieve the purpose of the push button 300 controlling the toggle switch 130 to turn on or off, but also because the movable slider 200 can abut against the inner side wall of the accommodating chamber 110 and limit the movable slider 200 from passing through the bar through slot 101 to move outside the accommodating chamber 110, the push button 300 is tightly connected to the movable slider 200 and will not accidentally fall out of the bar through slot 101, so that the transmission connection between the push button 300 and the toggle switch 130 is firm and reliable, solving the technical problem that the push button of the traditional flashlight is easy to fall off.

[0037] It should be noted that, in the above-mentioned embodiment, the length of the movable slider 200 is greater than the length of the strip through slot 101, so that when the movable slider 200 moves along the length direction of the strip through slot 101, one end or both ends of the movable slider 200 can abut against the accommodating cavity 110. In some embodiments of the present utility model, the width of the movable slider 200 is greater than the width of the strip through slot 101, so when the movable slider 200 is close to the inner wall of the accommodating cavity 110 and moves along the length direction of the strip through slot 101, both sides of the movable slider 200 can continuously abut against the accommodating cavity 110, effectively preventing the movable slider 200 from passing through the strip through slot 101 and moving outside the accommodating cavity 110, which can be determined according to actual needs.
