Description

Technical Field

[0001] This utility model relates to the field of floor scrubbing machine technology, specifically to a structure for lifting and resetting the handle of a wastewater tank. Background Technology

[0002] Among various cleaning equipment, floor scrubbers have become an important tool in commercial, industrial, and even household cleaning fields due to their high efficiency, convenience, and environmental friendliness. By integrating key components such as brushes or suction cups, water tanks, motors, and control systems, floor scrubbers achieve automatic floor cleaning and drying in one operation. During the operation of a floor scrubber, the wastewater tank plays a crucial role. As a container for collecting wastewater, debris, and other dirt from the floor, the performance of the wastewater tank directly affects the cleaning effect and ease of operation of the floor scrubber. When using existing wastewater tanks, the connection between the tank cover and the tank body is relatively complex, making it difficult to quickly separate and disassemble them, thus reducing the disassembly efficiency of the wastewater tank.

[0003] Therefore, we proposed a structure for lifting and resetting the sewage tank handle to solve the problems mentioned above. Summary of the Invention

[0004] The purpose of this utility model is to provide a lifting and resetting structure for sewage tank handles, in order to solve the problem mentioned in the background art that the fixing structure between the cover and the tank body of existing sewage tanks on the market is relatively complex, making it inconvenient to quickly separate and disassemble them, thereby reducing the disassembly efficiency of the sewage tank.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sewage tank handle lifting and resetting structure, including a connecting handle and a sewage tank cover for mounting on the connecting handle. The sewage tank cover is mounted on the upper end of the sewage tank body. A reset torsion spring providing reset elasticity is provided at the rotating joint of the connecting handle. The inner side of the sewage tank body extends outward to form a protrusion, and the protrusion is used to provide a thrust when the connecting handle rotates into contact.

[0006] Preferably, a central shaft is installed on the side of the sewage tank cover, and a handle is rotatably mounted on the central shaft on the side of the sewage tank cover.

[0007] By adopting the above technical solution, the connecting handle can be rotated on the central axis of the sewage tank cover, thereby providing rotational support for the connecting handle.

[0008] Preferably, the contact surface between the protrusion and the connecting handle is set as an inclined side, and the end of the connecting handle near the inclined surface of the protrusion is set as an arc-shaped structure.

[0009] By adopting the above technical solution, when the connecting handle is rotated, its arc-shaped end comes into contact with the inclined edge of the protrusion, thereby enabling the protrusion to push the connecting handle upward.

[0010] Preferably, the end of the connecting handle has a hole for the positioning bolt to pass through, and the positioning bolt and the center shaft are threaded together.

[0011] By adopting the above technical solution, the connecting handle can be limited by the positioning bolts threaded on the central shaft, thus preventing the connecting handle from rotating and slipping off the central shaft.

[0012] Preferably, the cross-section of the connecting handle is set as a "U" shape, and positioning bolts are provided at both the left and right ends of the connecting handle.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the sewage tank handle lifting and reset structure can separate the two by lifting the handle and the tank cover when the handle is rotated through the connection between the handle and the tank cover. At the same time, the reset torsion spring facilitates the automatic return of the handle to its original position.

[0014] 1. It is equipped with a connecting handle. When the connecting handle is rotated, the arc surface at its end and the protrusion on the inclined surface of the sewage tank are pressed against each other, so that the protrusion can be used to push the connecting handle upward, thereby facilitating the separation and disassembly of the sewage tank cover and the sewage tank body.

[0015] 2. A reset torsion spring is provided. By setting the reset torsion spring at the rotating joint of the connecting handle, the connecting handle can be automatically reset by the rebound force of the reset torsion spring when the connecting handle is released.

[0016] 3. A positioning bolt is provided. The central shaft is located on the side of the sewage tank cover, which provides rotational support for the connecting handle. At the same time, the positioning bolt on the central shaft can limit the connecting handle and prevent it from rotating off the central shaft. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1: Please refer to Figures 1-3 The existing sewage tanks have a complex fixing structure between the tank cover and the tank body, which makes it difficult to quickly separate and disassemble them, thus reducing the disassembly efficiency of the sewage tank. In order to solve this technical problem, this embodiment discloses the following technical content: a sewage tank handle lifting and reset structure, including a connecting handle 1 and a sewage tank cover 2 for mounting on the connecting handle 1. The sewage tank cover 2 is mounted on the upper end of the sewage tank body 3. A reset torsion spring 4 is provided at the rotating joint of the connecting handle 1 to provide reset elasticity. The inner side of the sewage tank body 3 extends outward to form a protrusion 5, and the protrusion 5 is used to provide the thrust when the connecting handle 1 rotates and contacts. The contact surface between the protrusion 5 and the connecting handle 1 is set as an inclined side, and the end of the connecting handle 1 near the inclined surface of the protrusion 5 is set as an arc structure.

[0023] When it is necessary to disassemble the sewage tank cover 2 and the sewage tank body 3, the connecting handle 1 is rotated on the sewage tank cover 2. After the connecting handle 1 is rotated, the arc surface at its end abuts against the protrusion 5 on the inclined side of the sewage tank body 3. The protrusion 5 can then be used to push the connecting handle 1. Since the connecting handle 1 is installed on the sewage tank cover 2, the sewage tank cover 2 and the sewage tank body 3 can be quickly separated after the connecting handle 1 is squeezed.
