Abstract
The utility model discloses an antiabrasion automobile dust cover which comprises a dust cover (1), wherein the middle part of the dust cover (1) is a hollow bellows piece, and a support pad (2) is arranged at the minimum diameter part of the inner wall of the bellows piece of the dust cover (1); and a gas vent (3) is arranged on the inner wall of an upper opening sealing part or a lower opening sealing part of the dust cover (1). The support pad is adopted to be arranged on the inner wall of the bellows piece of the automobile dust cover, and plays to the roles of inner supporting and wear resisting, so the inner wall of the bellows piece cannot be directly contacted with an inner support rod, and is effectively prevented from abrading with the inner support rod to cause damage. Moreover, the gas vent is arranged on the upper opening sealing part or the lower opening sealing part of the dust cover, so airflow is effectively exhausted, the abnormal sound which is generated by the impact of the airflow is avoided, and the abnormal sound problem which is caused by the impact of the airflow during the rotation process of a connecting rod in the existing dust cover is solved.
Description
Technical field
The utility model relates to a kind of automobile component, particularly a kind of vehicle dust protector.
Background technique
At present, vehicle dust protector mainly is the piston rod that prevents grit damage automobile.In the process of piston rod compression, air will pass through vehicle dust protector and discharge, and still, when exhausting air, air-flow can produce abnormal sound because impact, and the user can feel very ill; And because in the piston rod compression process, strut can come in contact with the corrugated pipe segment inwall of vehicle dust protector, after long-time the use, vehicle dust protector will be worn, and has influenced the working life of vehicle dust protector.
Summary of the invention
The utility model technical problem to be solved is: a kind of abrasionproof vehicle dust protector is provided; It has solved the problem that abnormal sound takes place existing vehicle dust protector in the piston rod compression process; And reduced the wearing and tearing that vehicle dust protector receives, to overcome the deficiency of existing technology.
The utility model be achieved in that the abrasionproof vehicle dust protector, comprise dust-proof cover, the middle part of dust-proof cover is the hollow bellows section, the top of dust-proof cover is the dust-proof cover linkage section, is provided with Support cushion at the minimum place of diameter of the corrugated pipe segment inwall of dust-proof cover; On the inwall of dust-proof cover sealing part suitable for reading or end opening sealing part, be provided with gas guide groove.
Support cushion is cylindrical or the spheroidal structure, and Support cushion is evenly distributed on the minimum place of diameter of corrugated pipe segment inwall.
Gas guide groove is more than two, and gas guide groove is evenly distributed on the inwall of dust-proof cover sealing part suitable for reading or end opening sealing part.Make the discharge of gas more smooth.
Owing to adopted technique scheme; Compared with prior art; The utility model is employed on the corrugated pipe segment inwall of vehicle dust protector Support cushion is set; Played interior support and antiwear effect, made the corrugated pipe segment inwall can directly not touch strut, prevented that effectively corrugated pipe segment inwall and strut from friction taking place and produce damaged anti-.And on upper and lower mouthful of sealing part of dust-proof cover, gas guide groove is set, and air-flow is discharged smoothly, avoided air-flow because of impacting the abnormal sound that produces, solved existing dust-proof cover problem because of gas shock generation abnormal sound in the connecting rod rotation process.The utility model is simple in structure, and using effect is very good.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model;
Accompanying drawing 2 is the plan view of accompanying drawing 1.
Embodiment
The embodiment of the utility model: the structure of abrasionproof vehicle dust protector is as shown in Figure 1; Comprise dust-proof cover 1; The middle part of dust-proof cover 1 is the hollow bellows shape, and minimum place is provided with Support cushion 2 at the diameter of the corrugated tube shape inwall at dust-proof cover 1 middle part, and Support cushion 2 is cylindrical (all Support cushion 2 equal lengths; And adopt rubber to make; Concrete length is according to the diameter decision of intermediate support bar), and its section is spheroidal, and Support cushion 2 is evenly distributed on the minimum place of diameter of the corrugated tube shape inwall of dust-proof cover 1; On the inwall of the sealing part suitable for reading of dust-proof cover 1, be provided with 3 equally distributed gas guide grooves 3, gas guide groove 3 is R0.5～R1, to the groove of the inwall depression of dust-proof cover linkage section.
Present embodiment only describes with the structure that gas guide groove 3 is set on the inwall of sealing part suitable for reading, and the structure that gas guide groove 3 is set in the end opening sealing part also is identical.
Claims (3)
1. an abrasionproof vehicle dust protector comprises dust-proof cover (1), and the middle part of dust-proof cover (1) is the hollow bellows section, it is characterized in that: minimum place is provided with Support cushion (2) at the diameter of the corrugated pipe segment inwall of dust-proof cover (1); On the inwall of dust-proof cover (1) sealing part suitable for reading or end opening sealing part, be provided with gas guide groove (3).
2. abrasionproof vehicle dust protector according to claim 1 is characterized in that: Support cushion (2) is cylindrical or spheroidal structure, and Support cushion (2) is evenly distributed on the minimum place of diameter of corrugated pipe segment inwall.
