Description

Technical Field

[0001] The utility model relates to the technical field of car washing flushing arms, in particular to a car washing flushing arm which is easy to assemble and disassemble. Background Art

[0002] A car wash arm is a protective arm used to wash cars. It can rotate to wash, but most car wash machines are shipped disassembled. When assembly is required, the traditional connection between the protective arm and the water shaft is a threaded connection. For example, in Chinese patent literature, the authorization announcement number CN204340986U, authorized and announced on May 20, 2015, describes an ectopic anti-collision rotating arm device, which includes a high-pressure water inlet shaft, a rotating arm transverse block, a rotating arm longitudinal block, and a small rotating arm connecting block. The high-pressure water inlet shaft is connected to the rotating arm transverse block by a threaded connection. The shortcomings of the existing technology are: due to the heavy weight of the flushing protective arm, multiple people are required to perform the rotating connection and installation, which is not only time-consuming and inefficient, but also the threaded connection will cause water leakage at the connection during high-pressure washing, resulting in poor reliability in the application of the car wash arm. Utility Model Content

[0003] In order to overcome the above-mentioned deficiencies in the prior art, the utility model provides a car washing flushing arm which is easy to assemble and disassemble, eliminates the need for the traditional rotating connection using threads, saves time and effort, and is quick to install.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] This application connects the rotating water-through shaft and the arm connecting block located at the end of the arm body through a lifting block, that is, the lifting block and the arm connecting block serve as a transit connection between the rotating water-through shaft and the arm body. Compared with the method of threaded connection of the end of the rotating water-through shaft to the arm body in the prior art, the connection is convenient and easy to disassemble and assemble.

[0007] Preferably, a mounting ring groove is provided on the rotating water-through shaft, and the lifting block is connected to the mounting ring groove. The lifting block is connected to the mounting ring groove to limit the position of the lifting block in the axial direction of the rotating water-through shaft, thereby ensuring the reliability of the connection between the rotating water-through shaft and the arm body.

[0008] Preferably, the mounting ring groove is provided with a radial guide bar, and the hoisting block is provided with a guide groove that cooperates with the guide bar, thereby improving the rotation synchronization between the hoisting block and the rotating water-through shaft, and facilitating the rotation of the arm body when the rotating water-through shaft rotates.

[0009] Preferably, the hoisting block includes a first hoisting block and a second hoisting block arranged opposite to each other, the first hoisting block and the second hoisting block being spliced ​​on the mounting ring groove. The first hoisting block and the second hoisting block embrace and fix the mounting ring groove of the rotating water-through shaft, which has a reliable structure and convenient connection.

[0010] Preferably, the water passage includes a first water guide hole and a second water guide hole, the first water guide hole being connected to and in communication with the rotating water-passing shaft, and the second water guide hole being connected to and in communication with the arm body. The first water guide hole is provided with a plurality of sealing rings that cooperate with the rotating water-passing shaft. The water passage achieves water flow reversal, and the provision of the sealing rings ensures a reliable sealing connection between the rotating water-passing shaft and the arm connecting block.

[0011] Preferably, a spiral groove is provided in the first water guide hole, and two sealing rings are provided, and the two sealing rings are arranged in the spiral groove at intervals, so as to achieve reliable sealing between the water guide hole and the rotating water shaft.

[0012] Preferably, the arm body comprises a horizontal section, an inclined section, and a vertical section arranged in sequence. The inclined section has a plurality of first water spray holes spaced apart, while the vertical section has a plurality of second water spray holes spaced apart. The spacing between adjacent second water spray holes is smaller than the spacing between adjacent first water spray holes. The inclined and vertical sections can spray water onto the vehicle body to complete the car wash. The vertical section aligns with the side of the vehicle body, thereby more densely distributing the water spray holes and achieving a better car wash effect.

[0013] Preferably, the horizontal section is connected to the second water guide hole, the horizontal section and the inclined section are connected to a first support piece, and the inclined section and the vertical section are connected to a second support piece, thereby improving the structural reliability of the arm body.

The spacing between adjacent second water spray holes 25 is smaller than the spacing between adjacent first water spray holes 23. A first support plate 26 connects the horizontal section 21 and the inclined section 22 at the angle between them, and a second support plate 27 connects the inclined section 22 and the vertical section 24 at the angle between them. The arm body 2 is covered with a buffer layer, and the buffer layer is opened corresponding to the first water spray hole 23 and the second water spray hole 25 respectively.

[0024] A hoisting block 3 is provided on the rotating water-passing shaft 1, and a mounting ring groove 11 is provided on the rotating water-passing shaft 1, and the hoisting block 3 is connected to the mounting ring groove 11. The hoisting block 3 is connected to the mounting ring groove 11, which limits the axial position of the hoisting block 3 on the rotating water-passing shaft 1, thereby ensuring the reliability of the connection between the rotating water-passing shaft 1 and the arm body 2. The mounting ring groove 11 is provided with a guide bar 12 arranged along the axis of the rotating water-passing shaft 1 in the radial direction of the mounting ring groove 11, and a guide groove 31 cooperating with the guide bar 12 is provided in the hoisting block 3.
