Description

Technical Field

[0001] This utility model relates to the field of squeegee technology, and in particular to a squeegee lifting and rotating mechanism. Background Technology

[0002] A squeegee is an important component used in cleaning equipment (such as floor scrubbers) to suck up wastewater and other debris from the floor during the cleaning process.

[0003] In the existing technology, the lifting and rotating mechanism of the squeegee has high friction between components during operation, which easily generates a lot of noise and accelerates component wear, affecting the service life of the mechanism. During the operation of the squeegee, it is not possible to ensure that the rubber strip is in close contact with the ground, which can easily lead to water splashing. At the same time, the lack of effective control and auxiliary structures during the lifting and lowering of the squeegee may lead to unstable operation, and the squeegee may collide with the machine body when swinging left and right, affecting the normal operation of the overall equipment. Utility Model Content

[0004] The purpose of this invention is to solve the problems in the prior art where noise is generated at the rotating connection when the squeegee rotates and the squeegee cannot ensure a tight fit between the rubber strip and the ground, which easily leads to water splashing. Therefore, this invention proposes a lifting and rotating mechanism for the squeegee.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a squeegee lifting and rotating mechanism, comprising a fixed bracket, a rotating bracket on the surface of the fixed bracket, a lifting bracket on the inner side of the rotating bracket, a threaded connection between the fixed bracket and the rotating bracket with a screw A, a screw B fixedly mounted on the side of the lifting bracket, a tension spring on the side of the rotating bracket, a double torsion spring sleeved on the surface of the screw B, a Teflon washer on the surface of the fixed bracket, a mounting bracket bolted to the surface of the lifting bracket, a rubber strip bolted to the inner side of the mounting bracket, a crash wheel bolted to the surface of the mounting bracket, a fixing plate bolted to the surface of the mounting bracket, a guide wheel bolted to the inner side of the fixing plate, and a suction pipe on the surface of the mounting bracket.

[0006] Preferably, the tervaron gasket is located between the fixed bracket and the rotating bracket.

[0007] Preferably, the number of the screws A is three sets, and the screws A are distributed in a triangular shape on the surface of the rotating bracket.

[0008] Preferably, the screw B is rotatably connected to the rotating bracket.

[0009] Preferably, the number of tension springs is two sets, and the tension springs are centrally distributed on the side of the rotating bracket.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] 1. In this utility model, by setting a Teflon gasket between the fixed bracket and the rotating bracket, the coefficient of friction during their rotational contact is effectively reduced, greatly reducing the noise generated during rotation and reducing wear between components. Simultaneously, three sets of triangularly distributed screws A securely connect and limit the rotating bracket, ensuring its rotational stability and preventing the squeegee from impacting the machine body when swinging left and right. The double torsion springs fitted on the screws B provide balanced ground pressure for the lifting bracket. When the squeegee descends, it ensures the rubber strip adheres tightly to the ground, effectively preventing water splashing. The tension spring design effectively solves the left-right balance problem of the squeegee. Attached Figure Description

Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0017] Example 1: As Figures 1-2As shown, this utility model provides a technical solution: a squeegee lifting and rotating mechanism, including a fixed bracket 1, a rotating bracket 2 on the surface of the fixed bracket 1, a lifting bracket 3 on the inner side of the rotating bracket 2, a threaded connection between the fixed bracket 1 and the rotating bracket 2 using a screw A4, a screw B5 fixedly mounted on the side of the lifting bracket 3, a tension spring 6 on the side of the rotating bracket 2, a double torsion spring 7 sleeved on the surface of the screw B5, a Teflon washer 8 on the surface of the fixed bracket 1, and a mounting bracket 9 bolted to the surface of the lifting bracket 3. An inner bolt is connected to a rubber strip 10. An anti-collision wheel 11 is bolted to the surface of the mounting bracket 9. A fixing plate 12 is bolted to the surface of the mounting bracket 9. A guide wheel 13 is bolted to the inner side of the fixing plate 12. A water suction pipe 14 is provided on the surface of the mounting bracket 9. A Teflon gasket 8 is located between the fixed bracket 1 and the rotating bracket 2. There are three sets of C-type screws A4, which are distributed in a triangular shape on the surface of the rotating bracket 2. C-type screws B5 are rotatably connected to the rotating bracket 2. There are two sets of tension springs 6, which are centrally distributed on the side of the rotating bracket 2.

[0018] In this embodiment, by setting a Teflon gasket between the fixed bracket 1 and the rotating bracket 2, the coefficient of friction during their rotational contact is effectively reduced, greatly reducing the noise generated during rotation and reducing wear between components. Simultaneously, three sets of triangularly distributed screws A securely connect and limit the rotating bracket 2, ensuring the stability of its rotation and preventing the squeegee from impacting the machine body when swinging left and right. The double torsion springs 7 sleeved on the screws B5 provide balanced ground pressure for the lifting bracket 3, ensuring the rubber strip 10 adheres tightly to the ground when the squeegee descends, effectively preventing water splashing. The design of the tension spring 6 effectively solves the problem of raising and lowering the squeegee.

[0019] The working principle of this embodiment is as follows: During use, by setting a Teflon gasket between the fixed bracket 1 and the rotating bracket 2, the coefficient of friction during their rotational contact is effectively reduced, greatly reducing the noise generated during rotation and reducing wear between components. Simultaneously, three sets of triangularly distributed screws A securely connect and limit the rotating bracket 2, ensuring the stability of its rotation and preventing the squeegee from impacting the machine body when swinging left and right. The double torsion springs 7 sleeved on the screws B5 provide balanced ground pressure for the lifting bracket 3. When the squeegee descends, it ensures that the rubber strip 10 is tightly attached to the ground, effectively preventing water splashing. At the same time, two sets of tension springs 6 centrally distributed on the sides of the rotating bracket 2 begin to function, maintaining the squeegee in a stable, centered position in the left-right direction and preventing it from shifting.
