Detailed Description

In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the following description of the present invention is provided with reference to the accompanying drawings, which are only some embodiments of the present invention, and it is obvious for a person skilled in the art to obtain other drawings without creative efforts.

As shown in fig. 1 to 5, the button assembly of the drain valve of the present invention includes a button body 10, a button 20, a button return elastic member 30, a button seat 40 and a balance mechanism. The key 20, the key return elastic member 30 and the button seat 40 are movably disposed in the button body 10. The button 20 drives the button seat 40, and the button seat 40 is linked with a connecting piece 70. The button 20 and the button seat 40 have a relative movable idle stroke, which is the relative movable stroke between the button 20 and the button seat 40. When the key 20 is pressed, the key 20 drives the key return elastic member 30 to be elastically deformed in the idle stroke. The balance mechanism is arranged between the key 20 and the button seat 40, and the key 20 can move relative to the button seat 40 smoothly by the idle stroke under the action of the balance mechanism.

In this embodiment, the balance mechanism is a balance bar 50, one end of the balance bar 50 is pivotally connected to one of the buckle base 40 and the button 20, and the other end is movably connected to the other of the buckle base 40 and the button 20. Specifically, in this embodiment, one end of the balance bar 50 is pivotally connected to the buckle base 40, and the other end is movably connected to the key 20, as shown in fig. 5, the key 20 is provided with a limiting groove 21, the other end of the balance bar 50 moves in the limiting groove 21, and the other end of the balance bar 50 does not separate from the limiting groove 21 during the movement of the key 20, so that the whole structure is more reliable.

In this embodiment, the key-returning elastic element 30 is a compression spring, the compression spring elastically pushes against between the key 20 and the fastening seat 40, and the key-returning elastic element 30 may also be an elastic member in other forms, such as a tension spring or a spring plate.

Preferably, in this embodiment, the balance bar 50 is a U-shaped structure, and includes a pivot and a fulcrum connected to two ends of the pivot, the pivot is pivotally connected to the buckle base 40, and the fulcrum moves in the limiting groove 21 on the key 20.

In this embodiment, the fastening device further includes a fastening seat elastic resetting element 60 for resetting the fastening seat 40, and the fastening seat elastic resetting element 60 is specifically a compression spring, but may be an elastic member in other forms. Preferably, the elastic force of the elastic latch resetting element 60 is greater than the elastic force of the elastic key resetting element 30, but not limited thereto, and the elastic force of the elastic latch resetting element 60 may be less than or equal to the elastic force of the elastic key resetting element 30.

In the present embodiment, when the button 20 is pressed, the button 20 slides the empty stroke relative to the fastening seat 40 and then drives the fastening seat 40 to slide, in this process, the button resetting elastic member 30 is compressed, the fastening seat 40 is further linked with the connecting member 70, and the connecting member 70 drives the starting member of the drain valve to open the drain valve for draining. After the pressing force is removed, the key 20 and the holder 40 are respectively reset by the key reset elastic member 30 and the holder elastic reset member 60.

Of course, in this embodiment, the button 20 may be pressed, and the button 20 drives the buckle seat 40 to slide in the process of sliding the idle stroke relative to the buckle seat 40, that is, the button 20 does not necessarily need to slide relative to the buckle seat 40 to drive the buckle seat 40 to slide after the idle stroke. The specific selection can be selected according to the needs.

The keys 20 of the present embodiment are provided with two keys, namely, a full row key 20a and a half row key 20b, in the present embodiment, the full row key 20a is taken as an example for description, and of course, the balancing mechanism may also be provided between the half row key 20b and the socket 40.

alternatively, the balance mechanism of the present embodiment may include a pair of cross arms (not shown) pivotally connected in a crossing manner, one end of each cross arm being connected to the key 20, and the other end thereof being connected to the holder 40. Specifically, the key 20 and/or the buckle seat 40 are provided with a guide groove or a guide convex rib at the connection part with the cross arm, a guide rib or a guide groove capable of being in sliding fit with the guide groove or the guide rib is arranged at the corresponding part of the cross arm, and the key 20 is pressed to drive the guide rib to move in the guide groove.

the utility model discloses set up an idle stroke between button and knot seat, through the button with set up a balance mechanism between the knot seat, be used for balancing the button for detaining the reciprocating motion of seat, can realizing under the limited condition of button spatial structure, the button does not receive the influence of guide part's length and intensity, can reach good balanced effect, can not block when pressing the button and die.

While the invention has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
