Abstract
The utility model relates to a brake flexible shaft guiding tube installation structure which comprises a seal ring. The brake flexible shaft guiding tube installation structure further comprises a connector, wherein a shoulder portion is arranged on the connector, the seal ring is fixed on the circumference of the shoulder portion, one end of the seal ring protrudes out of the axial end face of the shoulder portion, the circumference of one end of the connector is at least provided with a clamping jaw, and a gap is reserved between the clamping jaw and the shoulder portion of the connector. The brake flexible shaft guiding tube installation structure can prevent the problem of loosening after being connected with a vehicle body, and guarantees reliability of connection of a brake flexible shaft guiding tube and a vehicle body connecting piece.
Description
Technical field
The utility model relates to a kind of brake soft shaft guide pipe mounting structure.
Background technology
Hand braking flexible axle guide pipe as fixing, cooperated the sealing of O type circle by welding support on the pipe shaft in the past, was connected with the vehicle body assembly parts.Support cost and O type circle mounting structure tooling cost are higher, and support welding and O type circle mounting structure are twice moulding, the processing conformability is poor, in addition, welding is to be finished by artificial soldering, has unmatched risk in the locus with O type circle mounting structure, causes vehicle body assembling difficulty and risk of leakage, and cause guide pipe unreliable with being connected of vehicle body assembly parts, occur loosening after use a period of time.
Summary of the invention
For above-mentioned technical matters, the utility model provides a kind of brake soft shaft guide pipe mounting structure, and the utility model can prevent from being connected the rear loosening problem that occurs with vehicle body, guarantees the reliability that the brake soft shaft guide pipe is connected with the vehicle body attaching parts.
The technical scheme that solves the problems of the technologies described above is as follows:
Brake soft shaft guide pipe mounting structure, comprise seal ring, also comprise connector, this connector is provided with a shoulder, described seal ring is fixed on the periphery of shoulder, one end of sealing circle protrudes from the axial end of shoulder, connects on the side face of first end to be provided with at least a claw, leaves the interval between claw and the connector shoulder.
Adopted such scheme, connect on the side face of first end and be provided with at least a claw, leave the interval between claw and the connector shoulder, by this structure, when assembling with the vehicle body assembly parts, after connector passed through hole on the vehicle body assembly parts with an end of claw, rotate an angle, the vehicle body assembly parts are entered between claw and the connector shoulder leave the interval, and the brake soft shaft guide pipe only needs be connected with the other end of connector and gets final product, the mode that adopts can be injected into connector on the brake soft shaft guide pipe and get final product, and can guarantee axial pulling-out force like this, and it is loosening to avoid brake soft shaft guide pipe and vehicle body attaching parts to occur.When snapping onto between claw and the connector shoulder, the vehicle body assembly parts leave the interval, because the shoulder that arranges on the connector, seal ring is fixed on the periphery of shoulder, one end of sealing circle protrudes from the axial end of shoulder, the seal ring end that protrudes from the shoulder axial end can fit tightly with the vehicle body attaching parts like this, improves leak tightness between the two.
Further, the other end of described connector is provided with through hole.Can be convenient to be connected with the brake soft shaft guide pipe by this hole.
The periphery of described shoulder is provided with circular groove, and the internal face of described seal ring is provided with annular protrusion, and this annular protrusion cooperates with described circular groove.By projection and the cooperating of circular groove, seal ring can be securely fixed on the shoulder, improve the reliability of both connections.
The outer circumference surface of described seal ring is provided with the lug boss of annular, and this annular boss is between two ends of seal ring.Lug boss can increase the intensity of seal ring, when the vehicle body attaching parts snaps onto when leaving the interval between claw and the connector shoulder, the vehicle body attaching parts produces a squeezing action power to seal ring, because the existence of lug boss, the end of seal ring is formed restriction power, thereby so that seal ring fit tightly with the formation of vehicle body attaching parts.
Described connector is the connector of injection mo(u)lding.Connector adopts injection mo(u)lding, and at first size guarantees that by mold cavity dimensional accuracy is higher.Conformability is better; Secondly the seal ring mounting structure of jointing and claw and reservation can be guaranteed both space accuracies of gauge, evades assembling difficulty and risk of leakage.Moreover owing to adopt the injection moulding disposal molding on material cost and cost of labor, obviously to be better than the former.
Description of drawings
Fig. 1 is block diagram of the present utility model;
Fig. 2 is the section-drawing of mounting structure;
In the accompanying drawing, 10 is seal ring, and 11 is annular protrusion, and 12 is lug boss, and 20 is connector, and 21 is shoulder, and 22 is claw, and 23 is the interval, and 24 is the hole, and 30 is the brake soft shaft guide pipe, and 40 is the vehicle body assembly parts.
The specific embodiment
With reference to Fig. 1 and Fig. 2, brake soft shaft guide pipe mounting structure of the present utility model comprises seal ring 10, also comprises connector 20.Described connector 20 is the connector of injection mo(u)lding.This connector 20 is provided with a shoulder 21, and the periphery of described shoulder is provided with circular groove, and the internal face of described seal ring 10 is provided with annular protrusion 11, and this annular protrusion 11 cooperates with described circular groove.The outer circumference surface of described seal ring 10 is provided with the lug boss 12 of annular, and this annular lug boss 12 is between two ends of seal ring.Described seal ring 10 is fixed on the periphery of shoulder, and an end of sealing circle 10 protrudes from the axial end of shoulder.At least be provided with a claw 22 on the side face of connector 20 1 ends, claw is 4 in the present embodiment, leaves interval 23 between claw 22 and the connector shoulder 21, the projection of claw 22 for forming from connector 20 side faces.The other end of described connector is provided with through hole 24.
When brake soft shaft guide pipe 30, vehicle body assembly parts 40 were assembled with connector, brake soft shaft guide pipe 30 was inserted with connector 20 and is injected into one.Connector 20 rotates an angle after passing through hole on the vehicle body assembly parts with an end of claw, the vehicle body assembly parts is entered into leave 23 places, interval between claw and the connector shoulder, can guarantee axial pulling-out force like this.
