Problems solved by technology

[0002] The existing key structure, especially the key structure of the drain valve, includes a key base and a key body. The set chute is slidingly matched, the friction value is relatively large, and because the sliding friction is affected by the friction coefficient, when there are many impurities or other pollutants in the water tank, the friction coefficient between the guide rib and the chute will Increase, resulting in a further increase in key force value, inconvenient to use

Embodiment Construction

[0035] Please check Figure 1 to Figure 6 , a preferred embodiment of the key structure, the key structure, which includes a key base 100, a key 200 and at least one rolling member.

[0036] The key base 100 is provided with an assembly cavity 110 . In this embodiment, the button base 100 includes a base body 120 and two extensions 130 fixedly connected to the base body 120, the number of the assembly cavities 110 is set to two, and the two assembly cavities 110 respectively pass through the base body 120 and the two The protruding part 130 is connected with the two assembly cavities located in the seat body 120 .

[0037]In this embodiment, the protruding portion 130 is provided with a support groove 131 connected to the assembly cavity 110 and a through hole 132 connected to the assembly cavity 110 , the support groove 131 is arranged opposite to the through hole 132 .

[0038] In this embodiment, the protruding part 130 is further provided with a protruding ring 133 locat...

Abstract

The invention discloses a key structure which comprises a key seat (100) and a key (200). The key seat (100) is provided with an assembling cavity (110), and the key (200) is movably arranged in the assembling cavity (110). The key structure is additionally provided with at least one rolling part, wherein the rolling part is installed on one of the key (200) and the key seat (100) in a rotating mode and is in rolling fit with the other one of the key and the key seat. The key (200) is pressed to drive the rolling part to roll to reduce the friction between the key (200) and the key seat (100). Compared with existing rolling fit between a guide rib and a slide groove, the friction generated by rolling fit is far smaller than the friction generated by slide fit. Thus, the pressing force for pressing the key is small.

Description

technical field [0001] The invention relates to a key structure. Background technique [0002] The existing key structure, especially the key structure of the drain valve, includes a key base and a key body. The set chute is slidingly matched, the friction value is relatively large, and because the sliding friction is affected by the friction coefficient, when there are many impurities or other pollutants in the water tank, the friction coefficient between the guide rib and the chute will Increase, resulting in a further increase in key force value, inconvenient to use. Contents of the invention [0003] The present invention provides a key structure, which overcomes the shortcomings of the background art. The technical solution adopted by the present invention to solve the technical problem is: button structure, which is characterized in that it includes a button base (100) and a button (200), the button base (100) is provided with an assembly cavity (110), the button (...
