Description

Technical Field

[0001] The utility model relates to the technical field of car washing cantilevers, in particular to a multi-arm rotatable car washing cantilever. Background Art

[0002] With the development of modern social economy, cars have become indispensable means of transportation, and the car ownership is also increasing continuously. Therefore, the demand for car washing machines is also growing day by day. The water pipes of traditional car washing machines are directly placed on the ground. During use, the water pipes are prone to damage due to long-term friction with the ground, and the users need to constantly drag the water pipes to wash the cars, which is time-consuming and laborious. The birth of the car washing cantilever solves the disadvantages of directly placing the water pipes on the ground, improves the car washing efficiency, and provides a more comfortable and convenient car washing experience for users.

[0003] At present, the commonly used car washing cantilevers are generally double-arm type. There are usually the following two usage methods for double-arm car washing cantilevers. One is to use one pipe to realize the functions of spraying clean water and car washing foam, and the other pipe to realize the function of dust removal. This leads to inconvenient operation, and the viscosity and corrosiveness of the car washing foam are likely to cause the pipes to be blocked and corroded. If the pipes are damaged, both clean water and car washing foam cannot be used, affecting the normal operation of the equipment; the other method is to use one pipe to realize the function of spraying clean water, and the other pipe to realize the function of spraying car washing foam. This cannot meet the user's need for dust removal, resulting in a poor car washing experience. Therefore, it is of great significance to design a car washing cantilever that can independently and non-interferingly realize the three functions of spraying clean water, spraying car washing foam and dust removal.

[0030] Embodiment 1:

[0031] AsFigures 1 to 5 As shown, Example 1 provided by the present utility model is as follows:

[0032] The multi-arm rotatable car washing cantilever includes a mounting bracket 1, a barrel shaft 2, and a fixing plate 3. The mounting bracket 1 includes a column 101, a mounting rod 102, and a mounting base plate 103. One end of the column 101 is connected to the mounting rod 102 and the other end is connected to the mounting base plate 103. The mounting base plate 103 can be connected to the ground, wall, suspension, etc.

[0033] In order to increase the force-bearing area, the barrel shaft 2 is connected to the mounting rod 102 through the fixing plate 3. The fixing plate 3 includes an upper fixing plate 31 and a lower fixing plate 32. The barrel shaft 2 includes an upper shaft body and a lower shaft body. The upper shaft body is connected to the upper side of the mounting rod 102 through the upper fixing plate 31, and the lower shaft body is connected to the lower side of the mounting rod 102 through the lower fixing plate 32. The upper shaft body and the parts thereon can be pre-assembled into a whole, and the lower shaft body and the parts thereon can also be pre-assembled into a whole. In this way, modular assembly is realized, which is beneficial to improving the processing efficiency.

[0034] The multi-arm rotatable car washing cantilever further includes at least three rotating rods 4. In this embodiment, taking the setting of three rotating rods as an example, and they are respectively the first rotating rod 41, the second rotating rod 42, and the third rotating rod 43. The three rotating rods 4 are axially spaced along the barrel shaft 2. The three rotating rods 4 are all rotatably connected to the barrel shaft 2 through bearing sleeve assemblies, which facilitates the user to easily rotate the cleaning pipe and clean the vehicle from different angles. Among them, the first rotating rod 41, the second rotating rod 42, and the third rotating rod 43 are arranged in sequence from top to bottom. Preferably, the first rotating rod 41 is used to install the dust removal pipe, the second rotating rod 42 is used to install the foam cleaning pipe, and the third rotating rod 43 is used to install the clear water cleaning pipe. In car washing, the clear water cleaning pipe has the highest usage frequency, so it is arranged at the bottom to facilitate its rotation.

[0035] In order for the three rotating rods 4 to be used independently, two mutually independent flow channel structures are provided on the cylinder shaft 2. Generally, the number of flow channel structures matches the number of rotating rods 4 that need to be supplied with the medium. In this embodiment, the second rotating rod 42 and the third rotating rod 43 are respectively independently capable of realizing the functions of foam cleaning and clean water cleaning. If one of the cleaning pipelines is damaged, it will not affect the continuous operation of other functions. The flow channel structure includes a medium inlet joint 21, a channel 22, a rotating member 23 and a medium outlet joint 24. Among them, the rotating member 23 and the medium outlet joint 24 can be integrally or separately connected. The channel 22 is arranged axially along the cylinder shaft 2 therein. The rotating member 23 is rotatably arranged on the cylinder shaft 2 and a rotating flow channel 25 is provided thereon. The medium outlet joint 24 is arranged on the rotating member 23 and is communicated with the channel 22 through the rotating flow channel 25. The medium inlet joint 21 is arranged on the cylinder shaft 2 and is communicated with the channel 22. The rotating flow channel 25 is used to maintain the communication between the channel 22 and the medium outlet joint 24 when the rotating member 23 rotates.

[0036] The rotating member 23 is sleeved on the cylinder shaft 2. The rotating flow channel 25 is an annular flow channel arranged circumferentially between the inner wall of the rotating member 23 and the outer wall of the cylinder shaft 2. An overflow hole 26 is provided on the circumferential side wall of the cylinder shaft 2 to communicate the rotating flow channel 25 with the corresponding channel 22, ensuring that when the rotating member 23 rotates, the flow channel structure remains connected and does not affect the flow of the medium.

[0037] An O-ring seal 7 is provided between the inner wall of the rotating member 23 and the outer wall of the cylinder shaft 2. The O-ring seals 7 are symmetrically distributed on both sides of the rotating flow channel 25 respectively, preventing the medium from leaking and ensuring the sealing performance between the rotating member 23 and the cylinder shaft 2.

[0038] Each medium inlet joint 21 is arranged on the cylinder shaft 2 and is at the same horizontal height, which is convenient for operation, inspection and maintenance when connecting the car washing equipment or replacing the pipeline, and is also beneficial to the overall aesthetics.

[0039] An installation channel is provided on each rotating rod 4 and runs through axially along it. The orthographic projection of the medium outlet joint 24 is within the orthographic projection of the installation channel, avoiding excessive bending of the pipeline after the medium outlet joint 24 is connected to the clean water cleaning pipeline and the foam cleaning pipeline, which may cause pipeline wear.

[0040] The bearing sleeve assembly is sleeved on the cylinder shaft 2 and includes a bearing sleeve 5 and a bearing 6. Bearings 6 are symmetrically arranged up and down between the inner wall of the bearing sleeve 5 and the outer wall of the cylinder shaft 2, enabling the rotating rod 4 to rotate around the cylinder shaft 2.

[0041] Axial circlips 8 are provided on the upper and lower end faces of the bearing 6 to prevent the bearing 6 from moving axially, making the rotation of the rotating rod 4 more stable.

[0042] Embodiment 2:

[0043] As Figures 6 to 7 shown, Embodiment 2 provided by the present utility model is as follows:

[0044] The difference between this embodiment and Embodiment 1 lies in the setting manner of the rotating member 23 and the cylinder shaft 2. There are two setting manners of the rotating member 23 and the cylinder shaft 2 in this embodiment. When the rotating member 23 is sleeved on the cylinder shaft 2, the same setting manner as that in Embodiment 1 is adopted; when the rotating member 23 is located at the end of the cylinder shaft 2, the rotating member 23 is rotatably arranged at the end of the cylinder shaft 2. The rotating flow channel 25 is arranged along the axial direction of the rotating member 23 and is communicated with the channel 22. An overflow hole 26 for communicating the rotating flow channel 25 with the corresponding medium outlet joint 24 is arranged on the circumferential side plate of the rotating member 23. The rotating flow channel 25 is used to maintain the communication between the channel 22 and the medium outlet joint 24 when the rotating member 23 rotates.

[0045] The above-disclosed are only the preferred embodiments of the present utility model. Of course, the scope of the rights of the present utility model cannot be limited thereby.
