Description

Technical Field

[0001] The utility model relates to the field of shock absorbers, in particular to a novel regulating valve core structure of a shock absorber with an adjustable barrel. Background Art

[0002] The old design had a very fast adjustment effect, could not distinguish the approximate gear position, and the oil adjustment port was of irregular shape, which could easily cause the oil to foam and result in a significant reduction in the damping force. Summary of the invention

[0003] In order to solve the technical problem that the oil outlet is irregular and prone to foaming, the utility model provides a novel regulating valve core structure of a cylinder-adjustable shock absorber.

[0004] The technical solution of the utility model is as follows:

[0005] A novel regulating valve core structure of a cylinder-shaped adjustable shock absorber comprises an regulating seat, an inner wall of the regulating seat is provided with a contact surface, the contact surface contacts the regulating valve core, a gradient interface is provided at the head of the regulating valve core, an oil outlet is provided in the middle of the regulating valve core, a convex ring is provided in the middle of the regulating valve core, and the contact surface is sloped.

[0006] A concave groove is arranged at the front of the convex ring, and a sealing ring a is arranged in the concave groove.

[0007] The oil outlet is circular.

[0008] The regulating valve core is made of brass.

[0009] The convex ring is provided with a circular hole, a sealing member is provided in the circular hole, the convex ring is clamped into the clamping groove of the adjustment seat, and the sealing member contacts the elastic member.

[0010] The technical solution of the utility model has a novel structure and an ingenious and simple design. The surface treatment of the brass material is cancelled, thereby avoiding the dimensional error caused by the surface treatment. The oil outlet is designed to be circular, the oil outlet is smoother and more even, and the degree of oil foaming is reduced. The stepped flow channel controls the damping force design, and the change of the damping force is more regular and stable. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 2 It is a structural schematic diagram of the regulating valve core of the utility model. DETAILED DESCRIPTION

[0013] The utility model is further described below in conjunction with the accompanying drawings and embodiments. Example

[0014] like Figure 1 ,2 The regulating valve core structure of a novel cylindrical adjustable shock absorber shown in the figure includes an regulating seat, a contact surface 5 is provided on the inner wall of the regulating seat, the contact surface 5 is in contact with the regulating valve core 1, a gradient interface 2 is provided at the head of the regulating valve core 1, an oil outlet is provided in the middle of the regulating valve core 1, a convex ring 3 is provided in the middle of the regulating valve core 1, and the contact surface 5 is in the shape of a slope.

[0015] The front part of the convex ring 3 is provided with a concave groove, and a sealing ring a is provided in the concave groove.

[0016] The oil outlet is circular.

[0017] The regulating valve core 1 is made of brass.

[0018] The convex ring 3 is provided with a circular hole, in which a sealing member is provided. The convex ring 3 is inserted into the groove of the adjustment seat, and the sealing member contacts the elastic member.

[0019] When in use, the shock-absorbing oil is diverted from the return oil pipe to the adjusting seat through the oil chamber on the internal working cylinder. An adjusting valve core 1 is designed inside the adjusting seat. The adjusting valve core 1 rotates under the twisting of the external adjusting knob. The flow channel designed on the head of the adjusting valve core 1 shortens or increases the length of the flow channel by rotating left and right. The maximum gear is fully closed, and the minimum gear is when the oil outlet and the oil delivery hole are aligned. The oil delivery hole and the oil outlet in the adjustment system are interconnected. The rotation of the adjusting valve core 1 can shorten or lengthen the length between the two holes, which can be used to control the flow trend of the oil. It is used for adjustable shock absorbers, off-road vehicle shock absorbers, and barrel adjustable shock absorbers.

[0020] It should be understood that the above description is only a preferred embodiment of the present invention and is not sufficient to limit the technical solution of the present invention. For ordinary technicians in this field, within the spirit and principles of the present invention, additions, substitutions, changes or improvements can be made according to the above description, and all these additions, substitutions, changes or improved technical solutions should fall within the scope of protection of the claims attached to the present invention.
