[0040] The button 101 is a shell, and the outer panel extends out of the side plate 303 to facilitate hand pressing and applying force. The side plate 303 and the upper cover 301 are provided with a first opening, and the button 101 is arranged in the first opening and can slide in the first opening. The two sides of the button 101 shell have edges extending outward, which are used to limit the reset movement of the button 101. The lower part of the button 101 shell is the button bottom plate 103, which is connected to the panel of the button 101 shell. An upper lock buckle 104 is arranged in the middle of the button bottom plate 103. One end of the upper lock buckle 104 is fixed to the inner side of the panel of the button 101 shell, and the other end is a suspension end, and the suspension end has a downward inclined surface. The angle of the inclined surface is 120°-150°, and 150° is preferred in this embodiment. The length of the upper lock buckle 104 is greater than the length of the button bottom plate 103. When the first spring 102 is in a natural state, the end edge of the upper lock buckle 104 is located at the entrance of the space surrounded by the button support plate 203.

[0041] The bottom surface of the key bottom plate 103 and the upper lock buckle 104 are on the same surface. A slideway 3023 is provided at the corresponding position of the lower cover 302, and the key bottom plate 103 and the upper lock buckle 104 can slide on the slideway 3023 to realize the movement of the key 101. In order to enable the key 101 to be reset, the shell and the bottom plate of the key 101 are hollow, and a first spring 102 is provided inside.

[0042] When the button 101 is pressed in a direction perpendicular to the panel of the button 101, the button base plate 103 and the upper locking buckle 104 slide along the slideway 3023, and the first spring 102 is compressed; when the button 101 needs to be restored, the first spring 102 returns to its original length, driving the panel, the button base plate 103, and the upper locking buckle 104 to return to their original positions.

[0043] In this embodiment, the button 101 is arranged outside the side plate 303, so that the button 101 can be manually pressed to achieve unlocking. A slideway 3023 is arranged on the lower cover 302, and the upper lock buckle 104 can slide along the slideway 3023 so that the upper lock buckle 104 enters the unlocking space. The length of the upper lock buckle 104 is set to be greater than the length of the button bottom plate 103, so that when the upper lock buckle 104 is unlocked, the button bottom plate 103 will not affect the unlocking.

[0044] like Figure 4 and Figure 5 As shown, the button assembly 2 includes a button 201 , a button connecting plate 202 , a button supporting plate 203 , a lower locking buckle 204 , a button supporting rod 205 and a second spring 206 .

[0045] The button 201 is a block structure with an inclined surface at the top. The upper center of the upper cover 301 has a second opening, and the button 201 can move in the second opening. The button 201 is connected to the button connecting plate 202 below. The length and width of the button connecting plate 202 are greater than the length and width of the button 201, so that the button assembly 2 other than the button 201 cannot extend from the second opening, which plays a limiting role.

[0046] The button connecting plate 202 is supported by two button supporting plates 203 below. The two button supporting plates 203 enclose a space, which is an unlocking space. A lower lock buckle 204 is arranged in the space, and the upper part of the lower lock buckle 204 can be inserted into the upper lock buckle 104. The lower lock buckle 204 is arranged as an inclined surface, corresponding to the upper lock buckle 104. The inclined surface angle of the lower lock buckle 204 is the same as the inclined surface angle of the upper lock buckle 104, and the inclined surface direction of the lower lock buckle 204 faces upward. The lower lock buckle 204 is fixed between the two button supporting plates 203. It should be noted that the distance between the highest point of the inclined surface of the lower lock buckle 204 and the lower surface of the button 101 connecting plate is greater than the thickness of the edge of the upper lock buckle 104, so that the upper lock buckle 104 can be inserted.

[0047] In this embodiment, the upper lock buckle 104 and the lower lock buckle 204 are arranged in the unlocking space to realize unlocking, which can eliminate the influence of other components and facilitate unlocking.

[0048] Furthermore, button support rods 205 are provided on both sides of the unlocking space. Positioning rods 3022 are provided on the lower cover 302 at positions corresponding to the button support rods 205, which are used for positioning the button assembly 2 and for pressing and limiting the button assembly 2. In order to realize the reset function of the button 201, the button assembly 2 is provided with a second spring 206. The second spring 206 is sleeved on the outside of the button support rod 205 and the positioning rod 3022, with one end fixed to the lower cover 302 and the other end fixed to the button connecting plate 202.

[0049] Compared with the prior art, on the one hand, the button support rod 205 of this embodiment can support the button 201 and the button connecting plate 202 , and on the other hand, the button support rod 205 guides the movement direction of the second spring 206 .

[0050] In the natural state of the second spring 206, the button support rod 205 and the positioning rod 3022 sleeved inside the second spring 206 are not connected, the upper surface of the button 201 extends out of the second opening, and the upper surface of the button connecting plate 202 is in contact with the lower surface of the upper cover 301. When the button 201 is pressed downward, the second spring 206 is compressed, and the button support rod 205 moves downward until it is connected with the positioning rod 3022. At this time, the highest point of the upper surface of the button 201 is flush with the upper surface of the upper cover 301.

[0051] The button assembly 1 is connected to the lower cover 302 via the second spring 206 below. Further, in order to ensure that the button assembly 1 is stable during operation, the upper cover 301 is provided with a first vertical plate 3011 and a second vertical plate 3012, and the lower cover 302 is provided with a guard plate 3021. The first vertical plate 3011 and the second vertical plate 3012 are respectively provided at the front and rear of the button assembly 2, the bottom surface of the first vertical plate 3011 is higher than the upper surface of the upper lock buckle 104, and the bottom surface of the second vertical plate 3012 is higher than the upper surface of the guard plate 3021.

[0052] In this embodiment, the button 201 is configured to slide in the second opening, and the button 201 is unlocked when it is flush with the upper surface of the upper cover 301. When the upper surface of the button 201 extends out of the upper surface of the upper cover 301, it blocks the sliding of the object on the upper cover 301, thereby achieving locking. The structure is simple, and no complicated locking components are required.

[0053] The method of using this embodiment is as follows:

[0054] like Figure 6 As shown, when the button 101 is pressed, the button base plate 103 and the upper lock buckle 104 slide on the slideway 3023 toward the button 201, the first spring 102 is compressed, and the end inclined surface of the upper lock buckle 104 extends into the space surrounded by the button support plate 203, and slowly fits with the inclined surface of the lower lock buckle 204. When the upper lock buckle 104 extends to the top of the lower lock buckle 204, the lower lock buckle 204 is pressed down by the upper lock buckle 104, and the second spring 206 is compressed.

[0055] By pressing the button 101, the upper lock buckle 104 is withdrawn from above the lower lock buckle 204, and the upper lock buckle 104 slides outward under the action of the first spring 102. After the upper lock buckle 104 is withdrawn, the second spring 206 returns to its original length, and the button 201 moves upward and returns to its original position.

[0056] like Figure 7 As shown, when used to lock the external device 4, the external device 4 with the groove can be placed on the upper part of the upper cover 301. When the external device 4 slides from the button 101 end to the other end, the outer plane of the groove of the external device 4 passes through the button 201, pressing the button 201 downward, and compressing the second spring 206. When the external device 4 slides to the position of the groove corresponding to the button 201, there is no pressure on the button 201, the second spring 206 recovers, and pushes the button 201 upward, and the button 201 is stuck in the groove, locking the external device 4.

[0057] When unlocking is required, the side button 101 is pressed, and the upper lock buckle 104 of the button 101 extends into the upper part of the lower lock buckle 204 of the button 201, and the lower lock buckle 204 is pressed down, and the button 201 moves downward until the top of the button 201 is flush with the upper surface of the upper cover 301. The external device 4 is unlocked and can slide freely on the upper cover 301.

[0058] This embodiment adopts the form of upper and lower lock buckles, and adopts a spring-structured elastic part. The upper lock buckle 104 extends into the lower lock buckle 204 and presses the lower lock buckle 204 to move the button 201 downward, so that the groove component equipment is quickly unlocked. The structure is simple and compact, and it can be achieved by pressing the button 101, which is easy to use.
