[0017] In order to make the purpose, technical scheme and advantages of the utility model more clear and obvious, the utility model is described by the specific embodiments shown in the drawings below. However, it should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of the known structure and technology is omitted to avoid unnecessary confusion of the concept of the utility model.

[0018] Here, it also needs to be explained that, in order to avoid the utility model from being obscured by unnecessary details, only the structures and / or processing steps closely related to the scheme according to the utility model are shown in the drawings, and other details not closely related to the utility model are omitted.

[0019] Reference Figures 2-4As shown in the figure, the present specific embodiment adopts the following technical solutions: It includes a storage box cover plate 1, a storage box port frame 2, an unlocking button 3, a button compression spring 4, a hook lock torsion spring shaft seat 5, and a clamping lock 6; One side edge of the storage box cover plate 1 is movably clamped with an unlocking button 3. A button compression spring 4 is fixed to the internal latch of the unlocking button 3. The button compression spring 4 is inserted into the limit column inside the storage box cover plate 1 to achieve the pressing and reset of the unlocking button 3; And the inner side of the unlocking button 3 is connected with a clamping lock 6 through a hook lock torsion spring shaft seat 5. The clamping lock 6 is buckled with the storage box port frame 2 to fix the storage box cover plate 1. Among them, an integrated inclined guiding slope 31 is arranged in the middle of the unlocking button 3; The clamping lock 6 is in a "7" - shaped structure composed of an inclined driving arm 61 and a vertical locking hook 62; The upper end of the clamping lock 6 is provided with an inclined driving arm 61, and the lower end of the clamping lock 6 is provided with a vertical locking hook 62; The top end of the inclined driving arm 61 is in contact with the lower surface of the inclined guiding slope 31.

[0020] Among them, a smooth gasket is fitted between the inclined surface of the inclined guiding slope 31 and the top end of the inclined driving arm 61 to form a low - friction structure; The smooth gasket can greatly reduce the wear caused by friction and improve the service life; When the unlocking button 3 is pressed, the inclined guiding slope 31 moves inward, and under the guiding effect of the inclined surface, the inclined guiding slope 31 presses the inclined driving arm 61 downward, causing the clamping lock 6 to rotate around the hook lock torsion spring shaft seat 5 so that the vertical locking hook 62 disengages from the clamping to complete the unlocking.

[0021] In addition, both ends of the button compression spring 4 are respectively clamped on the convex column on the back of the unlocking button 3 and the convex column in the reserved groove of the storage box cover plate 1 for limit fixation; The vertical locking hook 62 is engaged with the reserved card slot on the edge of the storage box port frame 2.

[0022] The working principle of the present specific embodiment is as follows: When the unlocking button 3 is pressed, it slides to the right; The inclined guiding slope 31 inside the unlocking button 3 contacts the inclined driving arm 61 on the clamping lock 6, pushing the vertical locking hook 62 to rotate counterclockwise, thereby achieving unlocking. After the door body is unlocked, when the user releases the hand, the vertical locking hook 62 and the unlocking button 3 return to the starting position under the action of the button compression spring 4 and the hook lock torsion spring shaft seat 5 respectively. Since the inclined guiding slope 31 and the inclined driving arm 61 are in inclined surface contact, the ratio of the button stroke to the lock hook displacement can be controlled by controlling the angle of the inclined surface, achieving the purpose of extending the button stroke and preventing the user from accidentally touching the button.

[0023] In the limited space of the present specific embodiment, through the mechanical structure of inclined surface contact, the ratio between the pressing amount and the lock hook displacement amount is increased, so as to achieve the effect of extending the button stroke and preventing accidental touch.
