Description

Technical Field

[0001] The utility model relates to the technical field of toilet cover installation structures, in particular to a toilet cover locking structure. Background Art

[0002] Traditional toilet seats are mostly connected to the toilet base by bolt fastening. This bolt fixing mechanism can be divided into two designs: top locking and bottom locking.

[0003] The top-lock toilet seat installation method is mainly suitable for situations where the internal space of the toilet seat is compact or the installation location is difficult to reach. This type of design relies on a special locking structure. This structure generally includes a support base, bolts, and a matching expansion unit. The installation process usually involves pre-drilling holes on the ceramic surface of the toilet seat, then embedding the expansion unit into the hole, and then firmly fixing the support base to the hole where the expansion unit is located with bolts. The last step is to assemble the toilet cover and the pre-fixed support base in place, thereby completing the overall installation of the toilet cover.

[0004] For example, referring to a toilet cover quick installation bolt assembly shown in Chinese utility model patent CN204181551U, the assembly is equipped with a support base dedicated to fixing the cover, and a set of fixing devices consisting of bolts, nuts and washers placed on the bolts, wherein the bolt head is in close contact with the top interface of the preset adjustable hole on the support base. This structure allows the bolt to move in the adjustable hole and the support base itself to adapt to different installation position requirements.

[0005] However, there are still the following problems with such a locking toilet lid installation system:

[0006] 1. The adjustable hole is directly located inside the support base. Once this part is damaged during use, the support base may need to be replaced as a whole;

[0007] 2. The operation of adjusting the installation position is not convenient enough, and the support base needs to be rotated as a whole to change the direction of the adjustment hole, which increases the complexity of installation and maintenance.

[0008] In view of this, the inventor specially designed a toilet lid locking structure, and this case was thus generated. Utility Model Content

[0009] In order to solve the above problems, the technical solution of the utility model is as follows:

[0010] A toilet lid locking structure, comprising:

[0011] The support seat is designed with a through hole running from top to bottom, and a circle of inwardly protruding edge is arranged around the bottom edge of the through hole, and a through opening is opened in the middle of the edge;

[0012] An expansion unit, wherein a mounting hole is provided in the middle thereof;

[0013] a bolt having a threaded portion capable of threaded engagement with the mounting hole;

[0014] The adjusting piece has a shape that matches the through hole and can be movably overlapped with the top end of the clamping edge. A strip groove that matches the outer diameter of the threaded part of the bolt is arranged in the middle of the adjusting piece.

[0015] Preferably, the through hole is of circular structure, and the clamping edge correspondingly presents a closed ring structure that matches the contour of the through hole.

[0016] Preferably, the adjustment sheet is in the shape of a circular thin sheet, and its outer diameter is between the inner diameter of the through hole and the inner diameter of the clamping edge.

[0017] Preferably, a connecting base is integrally provided at the top of the supporting seat and located on one side of the through hole, and a rotating shaft which can be rotatably connected to the toilet cover is provided at the top of the connecting base.

[0018] Preferably, the interior of the rotating shaft is hollow in design, and a "U"-shaped bayonet is provided on its peripheral surface, and a barb structure is formed inside the bayonet.

[0019] Preferably, it further comprises a decorative panel integrally connected to the support base, and the end of the decorative panel is integrally connected to the support base via a flexible connecting sheet.

[0020] Preferably, one side of the flexible connecting piece is fixedly connected to the bottom of the side wall of the support seat, and the side wall of the support seat is provided with an embedding groove which is mutually embedded with the flexible connecting piece at the connection position of the flexible connecting piece.

[0021] Preferably, positioning holes are arranged at the top of the support seat and on both sides of the through hole, and positioning columns corresponding to the positions of the positioning holes are arranged on the inner wall of the decorative panel.

[0022] Preferably, the positioning hole is a waist-shaped hole and its extension distance is greater than the diameter of the positioning column.

[0023] Preferably, it also includes a gasket movably arranged at the bottom of the support seat, the bottom of the support seat is concave to form several weight-reducing areas arranged around the through hole, the top of the gasket is provided with multiple plug-in parts which are opposite to the weight-reducing areas and can be embedded and fixed, and the middle of the gasket is provided with a notch area corresponding to the middle opening of the card edge.

[0024] The beneficial effects of the utility model are as follows:

[0025] This solution enables the toilet cover to be conveniently and firmly locked on the support seat through the cooperation of the expansion unit, bolts and adjustment plates, thereby enhancing the stability of the toilet cover and avoiding loosening or displacement during use.

[0026] The circular through hole and closed ring clamp edge design have a compact and reasonable structure, which is convenient for assembly and disassembly, while ensuring the overall structural strength.

[0027] The rotating shaft is hollow in design and has a "U"-shaped bayonet and a barb structure, which facilitates the toilet cover to be connected in a rotating manner, ensuring smooth opening and closing of the toilet cover while effectively preventing accidental disengagement.

[0028] The decorative panel is integrated with the support base through a flexible connecting piece, which not only improves the overall aesthetics, but the design of the flexible connecting piece can also buffer impact and protect components from damage.

[0029] The coordinated design of the positioning holes and positioning columns enables the decorative panel to be accurately positioned and firmly fixed on the support seat, improving assembly accuracy and stability.

[0030] The design of the weight reduction area reduces the overall weight of the support base, which saves materials and reduces the load on the toilet cover. At the same time, the plug-in part on the gasket cooperates with the notch area and the weight reduction area to further enhance the stability of the lock and the safety of the toilet cover.

[0031] In summary, the toilet lid locking structure of the utility model has the advantages of simple structure, easy installation, high stability, good durability, etc., which greatly improves the user experience. BRIEF DESCRIPTION OF THE DRAWINGS
