Furthermore, a key groove is formed in one side of the main body, and the shape of the shaft sleeve is the same as that of the key groove, so that the shaft sleeve is fixedly embedded into the key groove.

Preferably, the key groove is used for forming an inclined arrangement between the outer convex part matched with the key and the horizontal plane.

Furthermore, a first plane is vertically arranged on the spherical cavity in the same axial direction of the moving direction of the wheel body, a second plane is arranged on the ball body, and the first plane and the second plane are abutted to limit the swinging direction of the shaft body.

Further, the main part has screw hole and the notch that supplies to hang the hub connection, screw hole and the coaxial intercommunication setting of notch.

Furthermore, the shaft body is connected with the wheel body in a matching mode through a bearing.

To sum up, the utility model discloses for its beneficial effect of prior art is:

the utility model has simple structure, the spherical cavity of the shaft sleeve is matched with the ball body of the shaft body, so that the shaft body of the connecting wheel body can realize the moving state of relative swinging, and when the dimensional deviation of the track and the hanging wheel system causes the sliding door to shake or the movement is blocked, the swinging motion of the shaft body reaches the self-balancing effect, and the smooth sliding of the matching between the hanging wheel and the track is realized; and the component structure is firm and simple, and is convenient for mass production and assembly.

Detailed Description

The invention will be further described with reference to the following description and embodiments in conjunction with the accompanying drawings:

as shown in fig. 1 to 4, an embodiment of the present invention preferably provides a swing type balance hanging wheel, which includes a main body 1, a wheel body 2, a shaft body 3 connected to the wheel body 2, and a shaft sleeve 4 sleeved on the shaft body 3; the axle sleeve 4 is formed by covering a first half bearing bush 5 and a second half bearing bush 6 and is provided with a spherical cavity 7, a ball 8 is arranged on the axle body 3 corresponding to the spherical cavity 7 in a matching manner, so that the axle body 3 can swing relative to the axle sleeve 4, the spherical cavity 7 of the axle sleeve 4 is matched with the ball 8 of the axle body 3, so that the axle body 3 connected with the axle body 2 can realize a relative swinging state, and therefore when the size deviation of a track and a hanging wheel system causes the door to move and swing or the track is blocked, the swinging movement of the axle body 3 achieves a self-balancing effect, and the smooth sliding of the matching between the hanging wheel and the track is realized.

The first half bearing shell 5 and the second half bearing shell 6 are provided with through holes 9 for the shaft body 3 to penetrate through, the central point of the spherical cavity 7 is arranged on the central shaft of the through holes 9, the first half bearing shell 5 and the second half bearing shell 6 are respectively sleeved on the shaft body 3 through the through holes 9 at two ends of the shaft body 3, so that the spherical cavity 7 is matched with the ball body 8, the components are simple, mass production and assembly are facilitated, and the stability of the shaft sleeve 4 formed by the shaft body 3 through the upper cover and the lower cover of the half bearing shell is superior to that of the half bearing shell.

One side of the main body 1 is provided with a key groove 10, and the shape of the shaft sleeve 4 is the same as that of the key groove 10, so that the shaft sleeve 4 is fixedly embedded into the key groove 10.

The keyway 10 is used for personally submitting the slope setting with key complex outer convex part and level, is being close to 1 side tip of main part at keyway 10 setting, and when 1 tip of main part was the rectangle form, keyway 10 was used for personally submitting the slope setting with key complex outer convex part and level to reach the straight line distance wall thickness that increases between keyway 10 and the 1 tip of main part, the steadiness of reinforcing structure.
