[0045] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0046] Example 1

[0047] like Figure 1 As shown, a locking assembly 10 disclosed in a first embodiment of the present invention includes a flexible connector 1 and a fixing plate 2. One end of the flexible connector 1 is connected to the fixing plate 2, and the flexible connector 1 and the fixing plate 2 are linked. A retaining structure 3 is provided on the flexible connector 1 to prevent the fixing plate 2 from moving. By applying force to the flexible connector 1, the fixing plate 2 can be moved so that it rests against a supporting member, such as the side of the toilet body 20. At the same time, the retaining structure 3 prevents the fixing plate 2 from moving, thereby quickly securing the fixing plate 2 for easy installation.

[0048] It should be noted that the supporting member is not limited to the toilet body 20, and may also be other components, such as a mounting plate on a table. The following embodiments all take the toilet body 20 as an example.

[0049] In this example, the limiting structure 3 is a limiting ball, which is arranged at the end of the flexible connector 1 away from the fixed plate 2, wherein a limiting hole can be provided on the supporting part such as the toilet body 20. When the fixed plate 2 is fixed to one side of the toilet body 20, the fixed plate 2 is tilted through the mounting hole 201 of the toilet body 20 and then returns to the center. Since one end of the flexible connector 1 is connected to the fixed plate 2, the flexible connector 1 is linked to the fixed plate 2, and a limiting ball is provided at the end of the flexible connector 1 away from the fixed plate 2. The limiting ball on the flexible connector 1 is stuck in the limiting hole to prevent the fixed plate 2 from moving, thereby limiting the fixed plate 2.

[0050] Example 2

[0051] like Figure 2As shown, a locking assembly 10 disclosed in a second embodiment of the present invention includes a flexible connector 1 and a fixing plate 2. One end of the flexible connector 1 is connected to the fixing plate 2, and the flexible connector 1 and the fixing plate 2 are linked. A retaining structure 3 is provided on the flexible connector 1 to prevent the fixing plate 2 from moving. By applying force to the flexible connector 1, the fixing plate 2 can be moved so that it rests against a supporting member, such as the side of the toilet body 20. At the same time, the retaining structure 3 prevents the fixing plate 2 from moving, thereby quickly securing the fixing plate 2 for easy installation.

[0052] In this example, the limiting structure 3 is a flexible connector 1 made of foldable metal material. When the fixing plate 2 is fixed to one side of the toilet body 20, the fixing plate 2 is tilted through the mounting hole 201 of the toilet body 20 and then returns to the center. After returning to the center, the flexible connector is folded, such as bending 90 degrees, so that the flexible connector 1 at the rear end of the folding can be pressed against the toilet body 20 to prevent the fixing plate 2 from moving, thereby limiting the fixing plate 2. The toilet body 20 can be provided with a limiting groove, and the flexible connector 1 at the rear end of the folding can be placed in the limiting groove to prevent shaking and improve stability.

[0053] Among them, the manufacturing material of the foldable metal flexible connector 1 is preferably aluminum or tinplate. The flexible connector 1 made of aluminum or tinplate has a certain hardness and can be bent under the action of external force to achieve positioning.

[0054] Example 3

[0055] like Figures 3 to 6 As shown, a locking assembly 10 disclosed in the third embodiment of the present invention includes a flexible connector 1, a fixing plate 2, and a hole plug 4; one end of the flexible connector 1 is connected to the fixing plate 2, and the other end of the flexible connector 1 passes through the hole plug 4. The flexible connector 1 and the fixing plate 2 are linked and can drive the fixing plate 2 close to the hole plug 4. The hole plug 4 or the flexible connector 1 and the hole plug 4 are provided with a limiting structure 3 to prevent the fixing plate 2 from moving away from the hole plug 4. By applying force to the flexible connector 1, the fixing plate 2 can be driven close to the hole plug 4 so that the fixing plate 2 rests on a supporting member, such as a side of the toilet body 20. At the same time, the limiting structure 3 prevents the fixing plate 2 from moving away from the hole plug 4, so that it can quickly fix the fixing plate 2 for easy installation.

[0056] When the fixing plate 2 is fixed to one side of the toilet body 20, after the fixing plate 2 passes through the toilet body 20, the flexible connector 1 is pulled so that the flexible connector 1 drives the fixing plate 2 to move, and the fixing plate 2 is close to the hole plug 4 and is located on one side of the toilet body 20. Then, the limiting structure 3 prevents the fixing plate 2 from moving away from the hole plug 4, so that the fixing plate 2 can be quickly fixed to facilitate the installation of the support 30.

[0057] In this example, a limit strip 31 is provided on the hole plug 4, one end of the limit strip 31 is elastically connected to the side wall of the hole plug 4, and the limit strip 31 and the side wall of the hole plug 4 form a limit channel 32 for the flexible connector 1 to be inserted; a plurality of first one-way teeth 311 are provided on the limit strip 31, and each first one-way tooth 311 includes a first sliding surface 3111 and a first abutting surface 3112; a plurality of second one-way teeth 33 are provided on the flexible connector 1, and each second one-way tooth 33 includes a second sliding surface 331 and a second abutting surface, and the second sliding surface 331 can slide along the first sliding surface 3111, and the second sliding surface 331 slides along the first sliding surface 3111 to the end of the first sliding surface 3111 and then jumps, so that the second abutting surface abuts against the first abutting surface 3112.

[0058] That is to say, the limiting structure 3 is a plurality of first one-way teeth 311 provided on the limiting bar 31 and a plurality of second one-way teeth 33 provided on the flexible connector 1, which cooperate with each other. When the flexible connector 1 is pulled, the second sliding surface 331 of the second one-way tooth 33 of the flexible connector 1 is driven to slide along the first sliding surface 3111 of the first one-way tooth 311. The second sliding surface 331 slides along the first sliding surface 3111 to the end of the first sliding surface 3111 and then jumps. Then, the flexible connector 1 can continue to be pulled to make the second sliding surface 331 of the next second one-way tooth 33 slide along the first sliding surface 3111 of the next first one-way tooth 311, thereby moving the fixing member 2 to one side of the toilet body 20 and tightly against the side of the toilet body 20 to facilitate the installation of the support 30.

[0059] In order to facilitate the production of the flexible connector 1 and the hole plug 3 and reduce production costs, the first abutment surface 3112 and the second abutment surface are preferably horizontal surfaces. Of course, they can also be inclined surfaces that can achieve the same effect, which is not limited here.

[0060] In this example, in order to achieve disassembly, the other end of the limiting strip 31 protrudes from the hole plug 4 to form a pressing portion 312. The pressing portion 312 is pressed to change the width of the limiting channel 32. That is, after pressing the pressing portion 312, the width of the limiting channel 32 can be driven to increase, thereby causing the second abutment surface to separate from the first abutment surface 3112, and the disassembly is completed.

[0061] In addition, in this example, two or more flexible connectors 1 are provided. In this manner, after one flexible connector 1 is detached from a limiting channel 32, the fixing plate 2 can be in an inclined state, and then the fixing plate 2 can be removed by pulling another flexible connector 1 to achieve reuse and reduce costs.

[0062] In this example, there are many types of connection methods between the fixing plate 2 and the flexible connector 1, such as Figure 3As shown, a through hole 21 can be provided on the fixing plate 2; a stopper 11 can be provided at one end of the flexible connector 1, and the other end of the flexible connector 1 passes through the through hole 21 on the fixing plate 2 so that the stopper 11 abuts against the fixing plate 2. In other words, the fixing plate 2 and the flexible connector 1 are separated so as to be manufactured separately, and then the stopper 11 is used for detachable connection. In addition, as Figure 5 As shown, a hinge rod can be provided at one end of the flexible connector 1, and a hinge hole can be provided on the side of the fixing plate 2. The hinge rod is placed in the hinge hole to connect the flexible connector 1 to the fixing plate 2.

[0063] Of course, the fixing plate 2 and the flexible connector 1 in this example can also be connected as one piece, as shown in FIG6 , where the flexible connector 1 and the bottom plate of the fixing plate 2 are integrally formed so that they can be manufactured using only one mold.

[0064] Example 4

[0065] like Figure 7 As shown, a locking assembly 10 is disclosed in Example 4 of the present invention. The difference between Example 4 of the present invention and Example 3 is that: the limiting structure 3 is a limiting ball, and the limiting ball is arranged at the end of the flexible connector 1 away from the fixed plate 2, wherein a limiting hole can be provided on the hole plug 4. When the fixed plate 2 is fixed to one side of the toilet body 20, the fixed plate 2 is tilted through the mounting hole 201 of the toilet body 20, and then returns to the center. Since one end of the flexible connector 1 is connected to the fixed plate 2, the flexible connector 1 is linked to the fixed plate 2, and a limiting ball is provided at the end of the flexible connector 1 away from the fixed plate 2. The limiting ball on the flexible connector 1 is stuck in the limiting hole on the hole plug 4 to prevent the fixed plate 2 from moving, thereby limiting the fixed plate 2.

[0066] Example 5

[0067] like Figure 8 As shown, a locking component 10 is disclosed in Example 5 of the present invention. The difference between Example 5 and Example 3 of the present invention is that: the limiting structure 3 is a flexible connector 1 made of foldable metal material, one end of the flexible connector 1 is connected to the fixing plate 2, and the other end of the flexible connector 1 passes through the hole plug 4. When the fixing plate 2 is fixed to one side of the toilet body 20, the fixing plate 2 is tilted through the mounting hole 201 of the toilet body 20, and then returns to the center. After returning to the center, the flexible connector is folded, such as bent 90 degrees, so that the flexible connector 1 at the rear end of the folding can be pressed against the toilet body 20 to prevent the fixing plate 2 from moving, thereby limiting the fixing plate 2, wherein the hole plug 4 can be provided with a limiting groove, and the flexible connector 1 at the rear end of the folding can be placed in the limiting groove of the hole plug 4 to prevent shaking and improve stability.

[0068] Example 6

[0069] In a locking assembly 10 disclosed in Example 6 of the present invention, the limiting structure 3 can be an elastic sheet, one end of which is elastically connected to the side wall of the hole plug 4. The other end of the elastic sheet and the side wall of the hole plug 4 form a socket for inserting the flexible connector 1, and the width of the socket is smaller than the width of the flexible connector 1. In other words, by providing the socket, the width of the socket is smaller than the width of the flexible connector 1. After the flexible connector 1 is inserted into the socket, the elastic sheet provides elastic force to drive the flexible connector 1 to a close contact with the side wall of the hole plug 4.

[0070] It should be noted that in this example, when the flexible connector 1 moves to be inserted into the socket, one end of the elastic sheet is elastically connected to the side wall of the hole plug 4, driving the socket to become larger to facilitate insertion of the socket. Then, when the flexible connector 1 stops moving, the elastic sheet provides elastic force to drive the flexible connector 1 close to the side wall of the hole plug 4 to achieve a limiting effect.

[0071] In some examples, the locking assembly 10 may further include a fastener 5, which passes through the hole plug 4 and is connected to the fixing plate 2. The fastener 5 may pass through the support 30 to facilitate fixing the support 30. The fastener 5 is preferably a fastening screw. Accordingly, the fixing plate 2 may be provided with a threaded hole 22, and the fastening screw is threadedly connected to the threaded hole 22.

[0072] Example 7

[0073] like Figures 9 to 14 As shown, a toilet disclosed in Example 7 of the present invention includes a toilet body 20, the above-mentioned locking assembly 10, a support 30 and a cover plate 40; a mounting hole 201 is provided on the toilet body 20; the fixing plate 2 passes through the mounting hole 201 at an angle, and the hole plug 4 is placed on the mounting hole 201, the flexible connector 1 is linked with the fixing plate 2, and drives the fixing plate 2 close to the hole plug 4, so that the fixing plate 2 rests on one side of the toilet body 20, and the limiting structure 3 prevents the fixing plate 2 from detaching from the toilet body 20; the fastener 5 passes through the support 30 and the hole plug 4 in sequence and is connected to the fixing plate 2, and fixes the support 30 to the other side of the toilet body 20; the cover plate 40 is connected to the support 30.

[0074] The support 30 is mounted on the toilet body with the aid of the locking assembly 10, and the cover 40 is mounted on the support 30. By applying force to the flexible connector 1, the fixing plate 2 can be driven toward the hole plug 4, so that the fixing plate 2 rests against the side of the toilet body 20. At the same time, the limiting structure 3 prevents the fixing plate 2 from moving away from the hole plug 4, thereby quickly securing the fixing plate 2 for easy installation.

[0075] The steps for fixing the support 30 with the locking assembly 10 of the present invention are as follows:

[0076] First, pass one end of the flexible connector 1 through the fixing plate 2 and the hole plug 4, and make the fixing plate 2 rest against the limit block 11 of the flexible connector 1. Second, as Figure 10As shown, the fixing plate 2 is tilted through the mounting hole 201 of the toilet body 20. Figure 11 As shown, place the hole plug 4 on the installation hole 201 of the toilet body 20, pull the flexible connector 1, drive the fixing plate 2 to press tightly against the toilet body 20, and the flexible connector 1 protruding from the toilet body 20 can be removed. Figure 12 and Figure 13 As shown, the support 30 is placed on the toilet body 20 and locked by tightening the screws. This allows the support 30 to be quickly fixed to the toilet body 20, and then, as shown in FIG. Figure 9 As shown, the cover plate 40 can be installed on the toilet body 20 through the support 30.

[0077] It should be noted that the flexible connector 1 is flexible, i.e., bendable, so that the fixing plate 2 is tilted to facilitate insertion through the mounting hole 201 of the toilet body 20. After insertion, the fixing plate 2 can be horizontal, so that both ends of the fixing plate 2 abut against the toilet body 20. The limiting structure 3 can keep the flexible connector 1 taut and prevent it from sliding down.

[0078] like Figure 14 As shown, when the support 30 needs to be disassembled, one of the pressing parts 312 is pressed to drive the width of one of the limiting channels 32 to increase, so that one of the flexible connectors 1 is separated from the limiting channel 32, so that the fixing plate 2 can be in an inclined state, and then the fixing plate 2 can be taken out by pulling another flexible connector 1 to achieve reuse and reduce costs.
