[0028] The following disclosure provides many different embodiments or examples for implementing different solutions of the present invention.

[0029] Reference Figures 1 to 5 As shown, a fence button is provided, including a lock upper cover 1 and a lock lower cover 8, the lock upper cover 1 covers the lock lower cover 8, a first hole 11 is provided on the lock upper cover 1, and slots 81 are provided on both sides of the lock lower cover 8;

[0030] The lock tongue 6 is horizontally movably arranged on both sides of the interior of the lock buckle lower cover 8, the outer end of the lock tongue 6 extends to the outside through the slot 81, the inner end of the lock tongue 6 abuts against one end of the lock tongue elastic member 7, and the other end of the lock tongue elastic member 7 abuts against the inner plane of the lock buckle lower cover 8;

[0031] A lock button 2, which is exposed above the lock cover 1 through the first hole 11;

[0032] The linkage slider 4 is vertically movably arranged inside the lock lower cover 8 and is arranged below the lock button 2. The linkage slider 4 abuts one end of the linkage slider elastic member 5, and the other end of the linkage slider elastic member 5 abuts the inner plane of the lock lower cover 8. Both sides of the linkage slider 4 abut against the lock tongue 6.

[0033] Furthermore, one side of the lock button 2 abuts against one end of the lock button elastic part 3, and the other end of the lock button elastic part 3 abuts against the linkage slider 4. The lock button 2 needs to be pushed in the direction of the linkage slider 4, and then the lock button 2 is pressed to make the lock tongue 6 move horizontally to achieve the effect of unlocking or self-locking. The function of this lock button elastic part 3 is to prevent children from accidentally touching it and improve safety.

[0034] In this embodiment, there are two locking tongues 6 in the lock lower cover 8, and the locking tongues 6 are respectively placed horizontally on both sides of the lock lower cover 8, and the outer ends of the locking tongues 6 extend to the outside through the slots 81 opened on both sides of the lock lower cover 8, and the inner ends of the locking tongues 6 abut against one end of the horizontally placed locking tongue elastic member 7, and the other end of the locking tongue elastic member 7 abuts against the internal support plane 82 of the lock lower cover 8. The locking tongue 6 can slide horizontally in the lock lower cover 8, and the horizontal sliding of the locking tongue 6 makes the outer end of the locking tongue 6 in a telescopic state. The other locking tongue 6 also has the same structure but is placed in a different direction; there is a lock button above the linkage slider 4 2, and the lock button 2 can move back and forth horizontally on the linkage slider 4 to a certain extent, one side of the lock button 2 abuts against one end of the lock button elastic member 3, and the other end of the lock button elastic member 3 abuts against the linkage slider 4; the linkage slider 4 abuts against one end of the linkage slider elastic member 5, and the other end of the linkage slider elastic member 5 abuts against the inner plane of the lock lower cover 8, and the linkage slider 4 can slide vertically up and down within the lock lower cover 8 to a certain extent; the lock upper cover 1 and the lock lower cover 8 are closed, including the above other components, but the lock button 2 is exposed to the top of the lock upper cover 1 so that the user can perform the unlocking operation.

[0035] In an embodiment of the present invention, a first inclined surface 61 is provided at the outer end of the locking tongue 6 , a reinforcing rib 62 is provided inside the locking tongue 6 , and a second inclined surface 621 is provided on the reinforcing rib 62 .

[0036] Furthermore, the second inclined surface 621 abuts against both sides of the linkage slider 4. When the lock button 2 is not pressed, both sides of the linkage slider 4 are located at the uppermost end of the reinforcing rib 62. During the pressing process, both sides of the linkage slider 4 slide on the second inclined surface 621, and the lock tongue 6 moves horizontally inward.

[0037] In one embodiment of the utility model, the lock lower cover 8 is L-shaped, and a plurality of support planes 82 are arranged inside the lock lower cover 8. The support planes 82 abut against one end of the lock tongue elastic member 7. When the button is released, the lock tongue is pushed to its original state.

[0038] Furthermore, a limiting member 83 is fixedly provided inside the lock lower cover 8, and the limiting member 83 is fixedly connected to one end of the linkage slider elastic member 5, and the limiting member 83 is used to fix the position of the linkage slider elastic member 5 to prevent it from moving.

[0039] In one embodiment of the present invention, a connection hole 84 is provided at the bottom of the lock lower cover 8, and the connection hole 84 is used to connect the fence pole to fix it.

[0040] In one embodiment of the utility model, the lock upper cover 1 is recessed inward to form a recess 12, and the first hole 11 is opened on the recess 12 to facilitate the user to perform unlocking operations, and the lock button 2 is used to cover the internal structure of the fence button.

[0041] How this fence key unlock works:

[0042] When the lock button 2 is half pressed, the linkage slider 4 will move downward at the same time, and the linkage slider 4 will squeeze the linkage slider elastic member 5 below it. Because the two sides of the linkage slider 4 abut against the second inclined surface 621 on the lock tongue 6, the downward movement of the linkage slider 4 will cause the lock tongue 6 to move horizontally toward the inside of the lock lower cover 8, thereby causing the outer end of the lock tongue 6 to retract, and at the same time, the lock tongue 6 squeezes the lock tongue elastic member 7; when the lock button 2 is continued to be pressed, the outer end of the lock tongue 6 will continue to retract until the lock button 2 is fully pressed, at which time the outer end of the lock tongue 6 will retract to its end position; when the lock button 2 is released, the linkage slider elastic member 5 will generate an upward thrust on the linkage slider 4 to reset it to its original state, and at the same time, the lock tongue elastic member 7 will generate a horizontal outward thrust on the lock tongue 6 to reset it to its original state.

[0043] The working principle of this fence button self-locking:

[0044] When the fence rod connecting piece (not shown) moves to the vicinity of the lock tongue 6 but does not abut against the lock tongue 6, the outer end of the lock tongue 6 completely extends to the outside of the lock lower cover 8. Because the lock tongue 6 does not move at this time, the lock tongue elastic member 7 abutted by the inner end of the lock tongue 6 is not compressed.

[0045] The fence rod connector continues to move and abuts against the outer end of the lock tongue 6. Because the abutting surface of the outer end of the lock tongue 6 is a slope 61, when the fence rod connector abuts against the first slope 61, the lock tongue 6 will move horizontally toward the inside of the lock lower cover 8, and at the same time squeeze the lock tongue elastic member 7.

[0046] When the fence rod connector continues to move and passes over the abutment surface at the outer end of the lock tongue 6, the lock tongue 6 moves horizontally toward the outside of the lock buckle lower cover 8 under the action of the lock tongue elastic member 7 and returns to its original position, thereby completing the self-locking of the lock buckle.

[0047] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
