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, a mounting assembly with a limiting member according to a first embodiment of the present invention includes a locked member 10 and a nut 20, the nut 20 is screwed with the locked member 10 to lock and fix the locked member 10 at a mounting hole 41 of a mounting base 40, and a limiting member 30 is further provided, and the limiting member 30 is selectively installed or not installed in a gap between an inner wall of the mounting hole 41 and an outer wall of the locked member 10.

The limiting member 30 can be selectively disposed on the nut 20, and the nut 20 drives the limiting member 30 to move; or alternatively, the locking member 10 is arranged on the locking member 10, and the locking member 10 drives the locking member 30 to move, or the locking member 10 is arranged independently and is independently arranged in or out of a gap between the inner wall of the mounting hole 41 and the outer wall of the locking member 10. The present embodiment adopts a structure in which the stopper 30 is provided on the nut 20.

The limiting member 30 can be selectively and fixedly arranged on the nut 20 or selectively and movably arranged on the nut 20, and can be switched between an unlimited locking position and a limited locking position, in the unlimited locking position, the limiting member 30 is not installed in a gap between the inner wall of the installation hole 41 and the outer wall of the fastened member 10; in the limit locking position, the limiting member 30 is fitted into a gap between an inner wall of the mounting hole 41 and an outer wall of the fastened member 10. The present embodiment adopts a mode that the limiting member 30 is fixedly disposed on the nut 20.

Specifically, the limiting member 30 is a convex portion fixedly disposed at an inner edge of one end of the nut 20, further, the convex portion is a convex ring extending along the circumferential direction of the nut 20, and an end surface of the other end of the nut 20 is a flat surface. The convex portion extends axially outward from the end portion of the nut 20, and when the stopper 30 is fitted into the gap between the inner wall of the fitting hole 41 and the outer wall of the fastened member 10 and the nut 20 is fastened to the fastened member 10, the end surface of the nut 20 having the convex portion abuts against the fitting surface on the fitting hole 41 side.

The fastened member 10 includes a threaded portion 12 and a limiting portion 11, the fastened member 10 is disposed through the mounting hole 41, the limiting portion 11 is in contact with and limits the mounting surface at one end of the mounting hole 41, and the nut 20 is in threaded connection with the threaded portion 12 to lock and fix the fastened member 10 at the mounting hole 41.

In this embodiment, the locked member 10 is a switch assembly for controlling a drain valve (not shown) in the toilet tank, the switch assembly is specifically a button assembly, the wall of the toilet tank is a mounting seat 40, and the wall of the toilet tank is provided with the mounting hole. Of course, the locked member 10 is not limited to this, and may be other products or parts that need to be locked.

In use, when the outer diameter of the fastened member 10 is smaller than the inner diameter of the mounting hole 41, as shown in fig. 1, it is necessary to fit the retaining member 30 into the gap between the inner wall of the mounting hole 41 and the outer wall of the fastened member 10, so as to fill the gap and make the whole assembly more stable after being fastened. When the outer diameter of the fastened member 10 matches the inner diameter of the mounting hole 41, it is not necessary to fit the retaining member 30 into the gap between the inner wall of the mounting hole 41 and the outer wall of the fastened member 10, and in this case, it is only necessary to rotate the nut 20 by 180 degrees in the state of fig. 1 to be screwed with the fastened member 10 in the state shown in fig. 3.

Alternatively, the projection may be at least two projections. The projections may include several and be circumferentially symmetrically disposed at the inner edge of the nut 20.

Alternatively, the position limiting element 30 is movably disposed on the nut 20 and can move between a position extending out of the nut 20 and a position retracting into the nut 20 along a radial direction or an axial direction of the nut 20, in the non-limiting locking position, the position limiting element 30 is retracted into the nut 20, and in the limiting locking position, the position limiting element 30 is extended out of the nut 20. Further, the length of the limiting member 30 extending out of the nut 20 in the radial direction or the axial direction can be adjusted, and the length of the limiting member 30 extending out of the nut 20 in the radial direction can be adjusted, so that the limiting member 30 can be better matched with the mounting holes 41 with different hole diameters; the length of the limiting member 30 axially extending out of the nut 20 is adjustable, so that the length of the limiting member 30 inserted into the gap between the inner wall of the mounting hole 41 and the outer wall of the locked member 10 can be adjusted as required, and the universal property is better.

As shown in fig. 6 and 7, a mounting assembly with a limiting member according to a second embodiment of the present invention is different from the above embodiments in that the limiting member 30 is disposed independently of the nut 20, and the limiting member 30 is independently installed in or withdrawn from a gap between an inner wall of the mounting hole 41 and an outer wall of the locked member 10. Specifically, the limiting member 30 is a limiting ring. The stopper 30 and the nut 20 are respectively provided at both sides of the mounting hole 41. The thickness of the limiting ring in fig. 6 is small and can be used for filling small gaps, the thickness of the limiting ring in fig. 7 is large and can be used for filling large gaps, and a plurality of limiting rings with different thicknesses can be arranged as required.

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.
