the specific embodiment is as follows: as shown in fig. 1-7, the present embodiment provides a fool-proof button structure, which includes a water tank upper cover 1, a button assembly, and a fool-proof assembly, wherein the water tank upper cover 1 is provided with a key hole 11 for installing the button assembly, and the fool-proof assembly is disposed between the key hole 11 and the button assembly to prevent an installation error of the button assembly.

In the embodiment, in order to realize fool-proof installation, a prompt structure which is convenient for distinguishing the installation direction is formed on the upper cover 1 of the water tank; the button subassembly includes left keypad 2 and right keypad 3, prevent that slow-witted subassembly is including locating the mistake proofing rib 21 on the 2 left edges of left keypad, locating single boss 12 on the wall of key hole 11 left side and locating the two boss 13 on the wall of key hole 11 right side, two boss 13 protrusion in the up end of water tank upper cover 1 to jack-up mistake proofing rib 21 suggestion installation is wrong when left keypad 2 is installed in the key hole 11 right side, just the length of two boss 13 is longer than the length of single boss 12, and the width of single boss 12 is wider than the width of two boss 13. Double boss 13 has a long boss and a short boss to constitute, when the assembly button subassembly, double boss 13 and single boss 12 width all broad that constitute by long boss and short boss, can not imbed and dodge in the groove 44, can cooperate with the outer wall of button body 4, restriction button body 4 moves left or right, guide button body 4 is installed perpendicularly in key hole 11, avoid long boss and right keypad 3 contact wherein, lead to right keypad 3 to appear pressing the problem of unsmooth, also can avoid short boss length alone, length is not enough to imbed and dodge in the groove 44, lead to preventing that slow-witted rib 21 can pack into the groove 44 of dodging of right keypad 3 one side, make the problem of preventing slow-witted function loss.

In the present embodiment, in order to mount the left key sheet 2 and the right key sheet 3, and prevent the single boss 12 and the double boss 13 from interfering with the mounting of the button body 4; be equipped with button body 4 in the key hole 11, be equipped with the button chamber 41 that is used for installing left keypad 2 and right keypad 3 in the button body 4, be equipped with on the lateral wall of button body 4 both sides and be used for dodging the installation and prevent slow-witted rib 21 and two boss 13 dodge groove 44.

In the present embodiment, in order to realize the basic functions of the key; the button assembly further comprises a spring 6, the left key board 2 and the right key board 3 are respectively provided with a key guide post 5 which extends downwards, a guide post hole for penetrating the key guide post 5 is formed in the key cavity 41, the spring 6 is sleeved on the key guide post 5, the spring 6 is arranged in the key cavity 41, the left key board 2 and the right key board 3 are further provided with an anti-falling hanging rod 7 which extends downwards, the bottom of the anti-falling hanging rod 7 is provided with an anti-falling hook 71, and the button body 4 is provided with a hanging hole 42 which is used for hooking the anti-falling hook 71 to prevent the left key board 2 and the right key board 3 from being separated from the key cavity 41.

In the present embodiment, in order to ensure the aesthetic appearance of the button assembly; the button assembly further comprises a decorative cover 8, the decorative cover 8 is buckled on the button body 4, an elastic clamping hook 81 is arranged on the decorative cover 8, and a clamping block 43 used for clamping the elastic clamping hook 81 is arranged on the button body 4.

The specific implementation process comprises the following steps: firstly, a spring 6 is placed in the button body 4, the button guide post 5 of the left button plate 2 penetrates through the spring 6, the fool-proof rib 21 is installed in one of the abdicating grooves of the button body 4, and meanwhile, the left button plate 2 is pressed downwards, so that the anti-falling hook 71 and the hanging hole 42 are clamped together, and the installation of the left button plate 2 is completed. Repeating the above operation, installing the right button plate 3 into the button body 4, because the right button plate 3 has no fool-proof rib 21, so the right button plate can be directly installed after being placed into the spring 6 (without the requirement of relevant direction). After the left key board 2 and the right key board 3 are mounted, the decoration cover 8 is directly covered on the button body 4 (without the requirement of relevant direction), and the assembly of the button assembly is completed.

When the button assembly and the upper water tank cover 1 are assembled, the avoidance groove 44 of the foolproof rib 21 of the left (right) key board is required to face the position of the single boss 12 of the upper water tank cover 1, the button assembly is pressed downwards, the double bosses 13 on the other side of the upper water tank cover 1 are inserted into the avoidance groove 44 of the other button body 4, and the button assembly can be correctly assembled on the upper water tank cover 1 by continuously pressing the button assembly. If the mistake has the groove 44 of dodging of preventing slow-witted rib 21 towards 1 two boss 13 positions of water tank upper cover with left (right) keypad during assembly workman's installation, then press the button subassembly downwards, at this moment, the slow-witted rib 21 of preventing of left (right) keypad will produce with the two boss 13 of water tank upper cover 1 and interfere, make the unable and 1 assembly parallel and level of water tank upper cover in button upper end, great clearance can appear, then give the feedback of assembler, remind button direction installation mistake, with this fool-proof installation that realizes the button direction.

The above description is only an embodiment of the present invention, and not intended to limit the scope of the utility model, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the specification and the drawings of the present invention, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
