Hidden water tank panel

Abstract

A hidden water tank panel comprises a panel body with a key hole, an installation frame installed on the back face of the panel body, a transmission rod arranged on the installation frame in a penetrating mode and a key hinged to the back face of the panel body and making contact with the transmission rod, and a hinge base is arranged on the back face of the panel body and provided with a hinge base plate, a hinge hole and a hinge base boss. The hinge seat bosses are located on the inner sides of the two oppositely-arranged hinge seats and surround the hinge hole, two hinge heads are connected to the two sides of the key respectively, and the hinge heads are inserted into the hinge hole to form hinge fit. And the hinge seat boss corresponds to the side surface of the key so as to limit the lateral deviation of the key. Due to the fact that the contact area of the key and the hinge seat boss is small, the friction force is small, the whole hinge fit structure is more stable through limiting fit, and the problems that when the key is pressed, pressing is strenuous, and the key deviates leftwards and rightwards are solved.

Description

Technical Field

[0001] The utility model relates to a hidden water tank panel. Background Art

[0002] In the technical field of toilet water tank equipment, especially the design of hidden water tank panels, since hidden water tank panels usually need to be embedded in the wall and are not easy to disassemble and repair, factors such as the ease of operation and structural stability of the water tank panels need to be considered. The existing hidden water tank panels are hinged with buttons, and the drain valve of the water tank is driven to drain water by pressing the buttons.

[0003] In order to make the pressing and resetting of the buttons smoother, the distance between the two hinged seats of the water tank panel is generally larger than the width of the buttons. However, there are deviations in the actual preparation. If the distance between the two hinged seats is too large, the buttons that are hinged with the hinged seats will be offset to the left and right, affecting the use; if the distance between the two hinged seats is reduced, the buttons will form a large area of ​​contact with the hinged seats, increasing the friction and affecting the pressing and resetting of the buttons.

Initially, the button 4 corresponds to the button hole 11, one end of the transmission rod 3 is in slidable contact with the button 4, the transmission rod 3 is inserted into the mounting frame 2 and moves forward and backward, and the other end of the transmission rod 3 is in contact with the toilet drain valve; when the button 4 is pressed, due to the hinged cooperation between the hinge head 6 and the hinge hole 52, the button 4 swings backward, pushing the transmission rod 3 and then driving the drain valve of the water tank to drain. Since the contact area between the button 4 and the hinge seat boss 53 is small, the friction force is small, and the overall hinged cooperation structure is more stable through the limit cooperation, the problems of laborious pressing when pressing the button 4 and the left and right deviation of the button 4 are solved.

[0034] Furthermore, the outer walls of the two limiting plates 131 are provided with inclined guide surfaces 132 corresponding to the side walls of the clearance window 41. When the button 4 is pressed to reset, if the position of the button 4 is offset, the side walls of the clearance window 41 can slide in contact with the inclined guide surfaces 132 of the outer walls of the limiting plates 131, so that the clearance window 41 of the button 4 can resume the limiting cooperation with the limiting plates 131.

[0035] Furthermore, the button 4 includes a pressing portion 42 and a connecting frame 43 that are connected to each other, the hinged head 6 is arranged on the connecting frame 43, and at the same time, the make way window 41 is also formed on the connecting frame 43; the pressing portion 42 is connected to the connecting frame 43 and corresponds to the button hole 11, the pressing portion 42 is provided with a button protrusion 44, and the back of the panel 1 has a button channel plate 14, when the pressing portion 42 of the button 4 is reset and moved into the button hole 11, the button protrusion 44 abuts against the button channel plate 14 to form a limiting fit, thereby making the position of the pressing portion 42 more fixed when it is reset to the button hole 11, and at this time the pressing portion 42 is flush with the surface of the panel 1.

[0036] Furthermore, the key protrusion 44 is equipped with an elastic buffer ring 45, and the key protrusion 44 contacts the key channel plate 13 through the elastic buffer ring 45 to form a limiting fit, and the elastic buffer ring 45 plays a role of buffering and limiting.

[0037] Furthermore, the button 4 has a plurality of vertically arranged ribs 46, and the first end of the transmission rod 3 corresponding to the button 4 is a spherical arc end 31. The spherical arc end 31 of the transmission rod 3 abuts against the rib 46, so that the spherical arc end 31 is in sliding contact with the rib 46 in the vertical direction, thereby preventing the spherical arc end 31 from shifting left and right when moving.

[0038] Furthermore, a limit hook 15 extending backward is also provided on the back of the panel 1 , and the limit hook 15 corresponds to the button 4 to limit the backward pressing stroke of the button 4 to avoid excessive pressing of the button 4 .

[0039] Furthermore, the back side of the panel 1 is surrounded by a panel enclosure 16, and the panel enclosure 16 is provided with a limiting ear 161. The mounting frame 2 is integrally formed with an elastic bent rod 21. The mounting frame 2 is assembled by pressing against the panel enclosure 16 through the elastic bent rod 21, and a limiting fit is formed by the limiting ear 161. The elastic deformation of the elastic bent rod 21 facilitates the installation and disassembly of the mounting frame 2.

[0040] Furthermore, the outer sides of the two hinge seats 5 arranged opposite to each other are provided with reinforcing ribs 55 , and the reinforcing ribs 55 play a role in reinforcing and supporting the hinge seats 5 .
