Description

Technical Field

[0001] This utility model relates to a transmission hook structure for a concealed water tank. Background Technology

[0002] Conventional toilet tanks adopt the traditional floor-standing toilet structure, with the tank mounted on the toilet bowl. Concealed tanks are also known as wall-mounted tanks. For example, patent number CN201921724459.0 discloses a concealed tank adapted to a smart toilet, and CN202120586739.0 discloses a concealed toilet tank mounting bracket.

[0003] When using the water tank, users drain water by pressing the drain button on the control panel. Normally, pressing the button lifts the drive rod via a transmission hook, opening the outlet and allowing water to flow. After releasing the button, the drive rod should fall back down under its own weight, refilling the tank. However, user feedback indicates that after a certain number of uses, the drive rod becomes stiff and doesn't fall cleanly. Disassembly revealed a jamming issue at the pivot point of the transmission hook, preventing it from properly resetting and keeping the drive rod in a pulled-up position.

[0004] Therefore, it is necessary to make further improvements. Utility Model Content

[0005] To address the aforementioned problems, the purpose of this utility model is to propose a transmission hook structure for water tank installation, which ensures that the transmission hook can be quickly reset after each operation.

[0006] To achieve the above objectives, this utility model provides a transmission hook structure for a concealed water tank, which includes a mounting bracket and a seat pivotally connected to the mounting bracket. The seat is provided with an outwardly extending hook portion, and the seat can rotate up and down relative to the mounting bracket. A reset member is provided between the mounting bracket and the seat, and the reset member applies downward pressure to the seat.

[0007] In one or more embodiments, the base body has pivot joints on both sides, and the mounting bracket has mounting plates on both sides of the base body, with pivot holes for pivoting with the pivot joints.

[0008] In one or more embodiments, the reset element is a torsion spring, which is sleeved on the base, with the first end of the torsion spring abutting against the mounting bracket and the second end of the torsion spring abutting against the base.

[0009] In one or more embodiments, the torsion spring and the hook are located at opposite ends of the seat.

[0010] In one or more embodiments, the mounting bracket and the base are provided with limiting grooves, and the two limiting grooves are used to connect to the first end and the second end of the torsion spring, respectively.

[0011] In one or more embodiments, the hook and the seat are injection molded as a single unit.

[0012] Compared with the prior art, the advantages of this utility model are: by setting a reset component between the mounting bracket and the base, the elastic force of the reset component is used to maintain the application of elastic force to the base. Therefore, each time the base rotates upward and drives the hook to hook the drive rod upward, and after the user releases the applied force, the base can quickly drive the hook to reset. Attached Figure Description

[0013] Figure 1 This is a schematic diagram of the transmission hook in this embodiment. Detailed Implementation

[0014] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0015] See appendix Figure 1 This application provides a transmission hook structure for a concealed water tank, which includes a mounting bracket 1 and a seat 2 pivotally connected to the mounting bracket. The seat 2 is provided with an outwardly extending hook 3, which is used to connect with a drive rod on the water tank. The seat 2 can rotate up and down relative to the mounting bracket 1. A reset member 4 is provided between the mounting bracket 1 and the seat 2. The reset member applies downward pressure to the seat 2. Each time the user operates, he will apply an upward rotational force to the seat, thereby lifting the drive rod. When the user stops applying force, the seat can quickly rotate downward and reset under the elastic force of the reset member, so that the hook 3 no longer lifts the drive rod, and also ensures that the water outlet of the water tank can be closed after the drive rod falls.

[0016] The seat body 2 is provided with pivot parts 5 on both sides. The mounting bracket 1 is provided with mounting plates 6 on both sides of the seat body 2. The mounting plates have pivot holes that are pivotally connected to the pivot parts 5. The pivot parts are specifically shafts. By connecting the pivot parts with the pivot holes, the seat body can be ensured to rotate smoothly, and the seat body can rotate downward more quickly under the elastic force of the reset member.

[0017] The reset component 4 is a torsion spring, which is sleeved on the base 2. The first end of the torsion spring abuts against the mounting bracket 1, and the second end of the torsion spring abuts against the base 2. The torsion spring can be specifically sleeved at the pivot position, and the torsion spring and the hook 3 are respectively located at both ends of the base 2 to avoid interference between the torsion spring and the hook.

[0018] The mounting bracket 1 and the base 2 are provided with limiting grooves 7. The two limiting grooves are used to connect to the first end and the second end of the torsion spring respectively. The limiting grooves can limit the first end and the second end of the torsion spring to prevent dislocation or displacement.

[0019] The hook 3 and the base 2 are injection molded as a single unit. The injection molded hook and base are tightly integrated and can eliminate the need for additional installation steps for the hook.

[0020] The above are merely preferred embodiments of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. Any equivalent modifications or changes made by those skilled in the art based on the content disclosed in the present utility model should be included within the protection scope recorded in the claims.
