Description

Technical Field

[0001] The utility model relates to the technical field of toilet cover installation, in particular to a quick disassembly and assembly structure of a toilet cover. Background Art

[0002] The toilet cover includes a seat ring and an upper cover, and is generally installed on the toilet body through a quick disassembly structure, so that the toilet cover is axially connected to the ceramic body of the toilet, so that the toilet cover can be lifted up or covered down.

[0003] In the prior art, the quick disassembly and assembly structure generally includes a sleeve, a button, a reversing member, a locking member and a supporting member. There are two reversing members and two locking members, which are divided into two groups and symmetrically arranged at both ends of the button. The above-mentioned button, reversing member and locking member are all matched in the sleeve, and the supporting member is fixed on the toilet body. The reversing member is moved by pressing the button, which drives the movement of the locking member, so that the locking member is locked or separated from the supporting member to complete the installation and removal of the toilet cover. Among them, a spring needs to be set between the reversing member and the locking member to ensure the structural stability of the locking member. The overall structure is relatively complex and the organization is troublesome, and it is not easy to operate for users. Utility Model Content

[0029] In order to further explain the technical solution of the present utility model, the present utility model is described in detail below through specific embodiments.

[0030] refer to Figures 1 to 8 As shown, the utility model discloses a quick disassembly and assembly structure of a toilet cover, comprising a fixing seat 1, a connecting member 2, a hinge device 3 and an elastic member 4;

[0031] The fixing seat 1 is provided with a positioning pin 11, and a limiting annular groove 12 is provided on the upper peripheral surface of the positioning pin 11;

[0032] The first end of the connecting member 2 is provided with a mounting hole 21 and a movable hole 22 which are parallel to the positioning pin 11, and a through hole 23 is connected between the movable hole 22 and the mounting hole 21;

[0033] The hinge device 3 is a hinge of the toilet cover, and its end is coaxially connected to the second end of the connecting member 2;

[0034] The elastic member 4 is pivotally engaged in the movable hole 22, and a first end thereof is provided with a limiting portion 41 which is penetrated through the through hole 23; the positioning pin 11 is penetrated through the mounting hole 21 and the limiting ring groove 12 is opposite to the through hole 23, and the second end of the elastic member 4 abuts against the hinge device 3 so that the first end thereof is embedded in the limiting ring groove 12 of the positioning pin 11 under the action of its own elastic force, thereby realizing relative fixation of the fixing seat 1 and the connecting member 2.

[0035] Through the above scheme, the utility model replaces the functions of the spring and the locking piece in the existing toilet hinge structure with the elastic piece 4, so that the whole structure is simpler, the product cost is low, and it is easy to assemble; during the disassembly and assembly of the toilet cover, it is only necessary to deform the limiting portion 41 of the elastic piece 4 to embed or disengage the limiting ring groove 12 of the positioning pin 11, so that the toilet cover can be quickly disassembled and assembled, the operation is very simple, and the user experience is good.

[0036] Specific embodiments of the present utility model are shown below.

[0037] In this embodiment, the limiting portion 41 is a hook-shaped structure bent at the first end of the elastic member 4 .

[0038] The upper end surface of the positioning pin 11 is provided with an annular bevel 13, and the lower edge of the end of the limiting portion 41 is provided with a guide bevel 411. The annular bevel 13 slides with the guide bevel 411 as the positioning pin 11 is inserted into the mounting hole 21. Figure 7 and Figure 8 During the installation process of the utility model, through the cooperation of the annular bevel 13 and the guide bevel 411, the end of the locating pin 11 can squeeze the limiting portion 41 inserted into the side wall of the mounting hole 21 when the locating pin 11 is inserted into the mounting hole 21, so that the locating pin 11 is inserted to the relative height of the limiting ring groove 12 and the through hole 23, so that the limiting portion 41 is embedded in the limiting ring groove 12; during the entire installation process, the user only needs to put the hinge device 3 with the connecting part 2 and the elastic part 4 on the locating pin 11, and there is no need to pry the elastic part 4 separately, which makes the operation simpler, and there is no chamfered structure in the disassembly direction, the limiting portion 41 will not easily fall off from the locating pin 11, ensuring the stability of the structure.

[0039] A rotating shaft 42 is provided in the middle of the elastic member 4 and is rotatably engaged with the side wall of the movable hole 22 .

[0040] The hinge device 3 is provided with a boss 31 on the end surface of the second end of the elastic member 4 for active engagement, see Figures 4 to 6 The second end of the elastic member 4 is engaged with the boss 31 as the hinge device 3 rotates. The boss 31 causes the elastic member 4 to swing so that the limiting portion 41 is separated from the through hole 23, thereby releasing the restriction on the positioning pin 11, and the hinge device 3 can be removed from the fixing seat 1. After the boss 31 is set, the user only needs to rotate the hinge device 3 (i.e., the toilet cover) to drive the elastic member 4 to swing through the boss 31, and then the limiting portion 41 of the elastic member 4 is ejected from the through hole 23. The user does not need to additionally move the elastic member 4 during the entire disassembly process, and the operation is simpler.

[0041] Furthermore, a paddle 32 is provided on the circumference of the hinge device 3 so as to rotate the hinge device 3 .

[0042] At the same time, a limiting piece 43 is provided at the second end of the elastic member 4, and a positioning groove 311 is provided in the middle of the boss 31 for the limiting piece 43 to be movably embedded. By embedding the limiting piece 43 in the positioning groove 311, the limiting portion 41 can be kept out of the through hole 23, which is convenient for disassembly.

[0043] The above embodiments and drawings do not limit the product form and style of the present utility model. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present utility model.
