Description

Technical Field

[0001] The utility model relates to the technical field of wall-mounted toilet installation, in particular to a quick-installation structure of a wall-mounted toilet. Background Art

[0002] In the prior art, a wall-mounted toilet is generally installed on a wall or a wall-mounted bracket using a locking device, and the locking device is engaged with and tightened on the bolt thread on the wall or the wall-mounted bracket. The bolts arranged on the wall or the wall-mounted bracket have the same bevel angle on both sides of the thread, in order to facilitate disassembly and assembly, and provide the same axial limiting force on both sides of the axial direction of the bolt.

[0003] However, in the actual installation process, due to the different thicknesses of walls / wall-mounted brackets of different manufacturers and users, as well as the influence of dimensional tolerances, the bolts and nuts of the locking device may have several circles of threads engaged when assembled, or may have only two or three circles of threads engaged. When a smaller number of threads are engaged, the axial limiting force provided will not meet the requirements. Under the action of gravity of the wall-mounted toilet, the locking device may loosen, causing the wall-mounted toilet to fall or break. Utility Model Content

[0004] The purpose of the utility model is to provide a quick-installation structure for a wall-mounted toilet, which solves the problems existing in the prior art and can be used to realize the quick assembly of the wall-mounted toilet and provide sufficient limiting force after assembly to prevent loosening.

[0005] In order to achieve the above object, one of the solutions of the utility model is:

[0006] A quick-installation structure for a wall-mounted toilet, comprising a nut member and a bolt member; the nut member is provided with a mounting hole, and the inner wall of the mounting hole is provided with a plurality of circles of first screw threads; the bolt member is movably inserted into the mounting hole, and a cantilever is provided on its circumferential surface, and a plurality of second screw threads matching the first screw threads are provided on the surface of the cantilever; in the disassembly and assembly direction of the nut member and the bolt member, the angle formed by the side surface of the first screw thread facing the bolt member and the inner wall of the mounting hole is 135 to 150°, and the angle b formed by the side surface of the first screw thread facing away from the bolt member and the inner wall of the mounting hole is 75 to 93°.

[0007] A limiting flange is arranged at the inner end of the mounting hole.

[0008] A limiting ring is arranged on the end of the circumferential surface of the bolt component away from the nut component.

[0009] An opening is arranged on the peripheral surface of the bolt member, one side of the cantilever is connected to the side wall of the opening, and the other end and both ends of the cantilever are separated from the side wall of the opening.

[0010] The nut member is provided with a column that penetrates the wall-mounted toilet, the mounting hole is provided in the column, and at least one pair of spring buckles are provided on the surface of the column.

[0011] The second solution of the utility model is:

[0012] A quick-installation structure for a wall-mounted toilet, comprising a nut member and a bolt member; the nut member is provided with a mounting hole, the inner wall of the mounting hole is provided with a cantilever, and the inner wall of the cantilever is provided with a plurality of first screw threads; the bolt member is movably inserted into the mounting hole, and a plurality of circles of second screw threads matching the first screw threads are provided on its circumferential surface; in the disassembly and assembly direction of the nut member and the bolt member, the angle formed by the side surface of the first screw thread facing the bolt member and the inner wall of the mounting hole is 135 to 150°, and the angle b formed by the side surface of the first screw thread facing away from the bolt member and the inner wall of the mounting hole is 75 to 93°.

[0013] A limiting flange is arranged at the inner end of the mounting hole.

[0014] A limiting ring is arranged on the end of the circumferential surface of the bolt component away from the nut component.

[0015] An opening is arranged on the peripheral surface of the nut member, one side of the cantilever is connected to the side wall of the opening, and the other end and both ends of the cantilever are separated from the side wall of the opening.

[0016] The nut member is provided with a column that penetrates the wall-mounted toilet, the mounting hole is provided in the column, and at least one pair of spring buckles are provided on the surface of the column.

[0017] After adopting the above technical solution, the utility model has the following technical effects:

[0018] The utility model designs the two side surfaces of the first screw thread and the second screw thread to have different slopes. In the process of assembling the nut member and the bolt member, since the second screw thread is arranged on the cantilever of the bolt member, and the opposite surfaces of the second screw thread and the first screw thread are at an obtuse angle of 135 to 150 degrees, the cantilever is more easily deformed by force when the first screw thread contacts the second screw thread, so that the second screw thread can pass over the first screw thread and be quickly inserted into the mounting hole. The installation depth of the bolt member in the mounting hole can be quickly shortened without turning the bolt member, and then the bolt member can be locked by turning the bolt member with a small number of turns, thereby achieving the purpose of rapid assembly.

[0038] refer to Figures 1 to 5 As shown, the first embodiment of the utility model discloses a quick-install structure of a wall-mounted toilet, including a nut member 1 and a bolt member 2;

[0039] The nut member 1 is provided with a mounting hole 11, and the inner wall of the mounting hole 11 is provided with a plurality of circles of first screw threads 12;

[0040] The bolt 2 is movably inserted into the mounting hole 11, and a cantilever 21 is provided on its circumference. A plurality of second screw threads 22 matching the first screw threads 12 are provided on the surface of the cantilever 21.

[0041] In the disassembly and assembly direction of the nut member 1 and the bolt member 2, the angle a formed by the side of the first thread 12 facing the bolt member 2 and the inner wall of the mounting hole 11 is 135~150°, and the angle b formed by the side of the first thread 12 facing away from the bolt member 2 and the inner wall of the mounting hole 11 is 75~93°, that is, the slopes of the two side surfaces of the first thread 12 are 135~150° and 75~93° respectively; correspondingly, the angle c formed by the side of the second thread 22 facing the nut member 1 and the peripheral surface of the bolt member 2 is 135~150°, and the angle c formed by the side of the second thread 22 facing away from the nut member 1 and the peripheral surface of the bolt member 2 is 75~93°, and a=c, b=d.

[0042] Specific embodiments of the present utility model are shown below.

[0043] A limiting flange 13 is provided at the inner end of the mounting hole 11 to limit the final mounting depth of the bolt member 2 .

[0044] A limiting ring 23 is provided on the end of the circumferential surface of the bolt member 2 away from the nut member 1. The limiting ring 23 is used to achieve axial limitation with the wall or the wall bracket to prevent the bolt member 2 from loosening from the wall or the wall bracket.

[0045] An opening 24 is provided on the circumferential surface of the bolt member 2, one side of the cantilever 21 is connected to the side wall of the opening 24, and the other end and both ends thereof are separated from the side wall of the opening 24, thereby limiting the deformation direction of the cantilever 21 to be on the radial plane of the bolt member 2. Even if the cantilever 21 cannot be completely reset to the factory state due to aging of the parts, each second thread 22 can still partially engage with the first thread 12 at the same time to ensure the locking force.

[0046] Furthermore, in this embodiment, the number of the openings 24 is two and they are spaced apart along the axial direction of the bolt member 2, that is, the number of the cantilever arms 21 is two. When the number of the second screw threads 22 needs to be designed to be greater, the second screw threads 22 are distributed on two or more cantilever arms 21, so that the area of ​​each cantilever arm 21 can be reduced to maintain elasticity and functional stability.

[0047] The nut member 1 is provided with a column 14 which is passed through the wall-mounted toilet, the mounting hole 11 is provided in the column 14, and at least one pair of spring buckles 15 are provided on the surface of the column 14 for tightly fitting the column 14 in the corresponding through hole of the wall-mounted toilet to play the role of installation limit.

[0048] See also Figures 2 to 5 Through the above scheme, the utility model designs the two side surfaces of the first screw thread 12 and the second screw thread 22 to have different slopes. During the assembly process of the nut member 1 and the bolt member 2, since the second screw thread 22 is arranged on the cantilever 21 of the bolt member 2, and the opposite surface of the second screw thread 22 and the first screw thread 12 is an obtuse angle of 135-150°, when the first screw thread 12 contacts the second screw thread 22, the cantilever 21 is more easily deformed by force so that the second screw thread 22 can pass over the first screw thread 12 and be quickly inserted into the mounting hole 11. The installation depth of the bolt member 2 in the mounting hole 11 can be quickly shortened without turning the bolt member 2, and then the bolt member 2 can be locked by turning it a small number of turns, thereby achieving the purpose of rapid assembly; at the same time, the opposite surface of the second screw thread 22 and the first screw thread 12 can achieve the purpose of axial limitation after the first screw thread 12 and the second screw thread 2 are engaged with each other, and provide sufficient limiting force and resistance when the bolt member 1 and the bolt member 2 have a tendency to disengage to prevent loosening.

[0049] refer to Figure 6 FIG. 2 shows a second embodiment of the present invention, which is mainly different from the first embodiment in that:

[0050] The cantilever 21 ′ and the opening 24 ′ of the second embodiment are arranged on the side wall of the mounting hole 11 of the nut member 1 , the first thread 12 is arranged on the cantilever 21 ′, and the second thread 22 is arranged on the circumferential surface of the bolt member 2 .

[0051] 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.
