detailed description

The technical solution of the utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in the figure, the swing arm system provided by the utility model includes a swing arm body and a swing arm seat. The swing arm body is composed of a support arm 10 and a rotating shaft 11. The support arm 10 is arranged horizontally and unfolded along the circumference of the rotating shaft 11. The support arm The interior of the support arm 10 is provided with a hollow cavity, and the upper surface of the support arm 10 is provided with a spray column 13 arranged obliquely. The nozzle of the spray column 13 communicates with the hollow cavity inside the support arm 10. The cavity in 11 is connected with the water outlet interface of the circulating water pump located below the swing arm system. After the circulating water pump is started, the water flow generated by the circulating water pump pushes the swing arm body to rotate adaptively; the swing arm seat includes a bottom plate 25 and Mounting opening 24 on the 25, base plate 25 is fixed on the tank bottom of tank type cleaning equipment. A buckle 22 is provided in the installation port 24, and a snap ring 31 is provided on the rotating shaft 11. When installing the main body of the swing arm, it is only necessary to align the rotating shaft 11 of the main body of the swing arm with the installation port 24, and apply a certain pressure downward, so that The buckle 22 fastens the snap ring 31 on the rotating shaft 11 to realize the installation of the swing arm body and the swing arm seat; The disengagement of the snap ring 31 removes the swing arm body from the swing arm seat. The entire swing arm system is simple in structure, easy to disassemble and assemble, and is convenient for multiple uses of the water tank.

A first stepped surface 21 and a second stepped surface 20 are provided from top to bottom in the installation opening 24 , and buckles 22 are evenly distributed on the first stepped surface 21 . The tapered transition surface, that is, the first stepped surface 21 and the first stepped surface 21 form a trumpet-shaped surface that opens upward. The setting position of the second stepped surface 20 is the same as the position where the rotating shaft 11 extends into the installation port 24, and the wall thickness at the bottom of the rotating shaft 11 is less than or equal to the width of the second stepped surface 20, so that the water flow generated by the circulating water pump can be pushed as small as possible. To the rotating shaft 11, the stability of the rotating shaft 11 when rotating is increased.

The bottom of the rotating shaft 11 is provided with a plurality of convex bodies 31 , which are block-shaped and uniformly distributed along the circumferential direction of the rotating shaft 11 . Due to the needs of rotation, there will be a certain gap between the rotating shaft 11 and the inner surface of the installation port 24. This gap will cause the rotating shaft 11 to move in series. Serial movement occurs during the rotation, which makes the spraying effect of the swing arm system better. On the other hand, the rotating shaft 11 will inevitably contact with the inner wall of the installation port 24 during the rotation, and the mutual contact will generate a certain friction force, thereby Affecting the rotation of the rotating shaft 11, the arrangement of the convex body 31 makes the contactable surface between the rotating shaft 11 and the inner wall of the installation port 24 smaller, thereby reducing the friction during the rotating process of the rotating shaft 11 and making the rotating shaft 11 rotate more smoothly.

The snap ring 31 is arranged at the upper middle of the rotating shaft 11, and the rotating shaft 11 is provided with a tapered transition surface between the snap ring 31 and the convex body 31, and this tapered transition surface corresponds to the tapered transition surface on the inner surface of the installation port 24. , setting the tapered transition surface can facilitate the insertion of the rotating shaft 11 into the installation port 24 .

The rotating shaft 11 is also provided with a retaining ring 32 between the snap ring 31 and the main body of the swing arm. The retaining ring 32 is used to reduce the gap between the rotating shaft 11 and the installation port 24 and play a certain role of sealing.

Fins 12 are arranged on the support arm 10 of the swing arm body, and when the objects to be cleaned in the tank are soaked, the fins 12 rotate with the swing arm body, so that the soaking water in the tank can generate eddy currents, which is better Soak the items to be cleaned in the sink.

The specific embodiments described herein are only examples to illustrate the spirit of the present invention. Those skilled in the technical field to which the utility model belongs can make various modifications or supplements to the described specific embodiments or adopt similar methods to replace them, but they will not deviate from the spirit of the utility model or go beyond the appended claims defined range.
