Detailed Description

The present invention will be described in further detail with reference to fig. 1 to 5.

The embodiment of the utility model discloses turn to structure assembly.

Referring to fig. 1, 2, 3, 4 and 5, a steering structure assembly comprises a handle pipe 1, a steering column 2 and a handle riser pipe 4 connected between the handle pipe 1 and the steering column 2, wherein the steering column 2 and the handle riser pipe 4 are sleeved with each other and limited in relative movement through a limiting device 5, and are connected with each other through a key 3 to limit relative rotation between the steering column 2 and the handle riser pipe 4. Through the setting of key 3, reduce the position difference of hand (hold) riser 4 among the assembling process, solve traditional mounting structure and can't lock after the assembly is accomplished, the atress still has less activity, increases hand (hold) pipe 1 and steering column 2 wholeness.

The handle tube and the handle vertical tube 4 are integrally formed, the mutual connection part of the handle vertical tube 4 and the direction column 2 is a cylinder, and the handle vertical tube 4 is sleeved with the direction column 2. In the present embodiment, the diameter of the handle stem 4 is larger than the diameter of the steering column 2, and the bottom of the handle stem 4 is open to receive the steering column 2.

In this embodiment, the key 3 is a flat key, the inner circle of the handle stem 4 has an inner key slot 11, the outer circle of the direction column 2 has an outer key slot 21, and the key 3 is cooperatively disposed between the inner key slot 11 and the outer key slot 21. When installing hand (hold) riser 4 on direction post 2, install key 3 in outer keyway 21 earlier, then at the in-process that direction post 2 inserted hand (hold) riser 4, key 3 and interior keyway 11 sliding fit make the horizontal both ends of key 3 set up with hand (hold) riser 4 and direction post 2 sliding fit respectively. The handle vertical pipe 4 and the direction column 2 are driven to rotate by the key 3 in the rotation process of the direction column 2; when the direction column 2 is locked, the rotation of the handle tube 1 is locked because the key 3 is clamped between the handle vertical tube 4 and the direction column 2. The problem of traditional mounting structure the fit clearance that exists after the assembly leads to unable lock, the less activity that the atress still has is solved.

In the present embodiment, the lateral direction refers to the radial direction of the steering column, and the vertical direction refers to the axial direction of the steering column 2.

In this embodiment, the handle stem 4 is made of carbon steel and has a certain deformation. The limiting device 5 comprises a support lug 51 and a compression assembly 52, an unloading hole 41 capable of transversely stretching and retracting is formed in the outer side wall of the bottom opening of the handle vertical pipe 4, and the unloading hole 41 can enable the distance between the two transverse ends of the unloading hole 41 to be lengthened or shortened by the aid of transverse force. Two support lugs 51 are fixedly mounted on the side walls of the two transverse ends of the unloading hole 41, the compression assembly 52 is used for compressing the unloading hole 41, the compression assembly 52 compresses the unloading hole 41 through compressing the two support lugs 51, so that the unloading hole 41 is contracted, and when the unloading hole 41 is in a contracted state, the handle stand pipe 4 limits the direction column 2 to move vertically.

In this embodiment, the compressing assembly 52 includes a locking bolt 521 and a locking nut 522, and the lug 51 is provided with a bolt hole for the locking bolt 521 to pass through. The lock nuts 522 pass through the bolt holes of the two lugs 51 and are in threaded connection with the lock nuts 522, and the compression amount of the unloading holes 41 is changed by adjusting the tightening degree of the lock nuts 522 by the lock nuts 522.

When the tightening degree of the locking bolt 521 and the locking nut 522 is relatively tight, the unloading hole 41 is contracted, so that the distance between the inner diameter of the handle vertical pipe 4 and the outer diameter of the direction column 2 is reduced, the key 3 is more tightly connected with the handle vertical pipe 4 and the direction column 2, meanwhile, the vertical movement of the direction column 2 is limited, and the consistency of the handle pipe 1 and the direction column 2 is improved.

In the present embodiment, the relief hole 41 is only opened on one side of the handle vertical pipe 4, so as to solve the risk of interference and abrasion between the front cable and the locking bolt 521 of the handle vertical pipe 4.
