Abstract
The utility model discloses an air pipe for a braking system. The air pipe for the braking system can prevent the end portion of a nylon pipe from being collapsed when a clamping sleeve is tightened. The air pipe for the braking system comprises the nylon pipe (1), nuts (2) are arranged at two ends of the nylon pipe (1), the outer surface of each end of the nylon pipe (1) is in interference fit with a clamping sleeve (3) so as to prevent the nut (2) at the corresponding end from being pulled out from the nylon pipe (1), each end of the nylon pipe (1) is provided with a hollow column-shaped bush (4), the outer surface of each bush (4) is in interference fit with the inner surface at the corresponding end of the nylon pipe (1), an annular protrusion (4.1) closely attached to the end face at the corresponding end is arranged at one end of the bush (4); and an anti-pulling pawl (4.2) is arranged on the outer surface of each bush (4).
Description
Technical field
The utility model relates to the brake system of car technical field, specifically is a kind of use for brake system tracheae.
Background technique
A kind of use for brake system tracheae is arranged at present, it generally comprises nylon tube, the nylon tube two ends are equipped with nut, nylon tube respectively holds cutting ferrule of the equal interference fit of outer surface to extract from nylon tube to stop a corresponding end nut, owing to adopt cutting ferrule, so when the assembling cutting ferrule, the situation that the nylon tube end subsides when existing cutting ferrule to tighten up.
The model utility content
The technical problems to be solved in the utility model is, a kind of use for brake system tracheae that the nylon tube end subsides when preventing that cutting ferrule from tightening up is provided.
The technical solution of the utility model is, the utility model use for brake system tracheae, it comprises nylon tube, the nylon tube two ends are equipped with nut, nylon tube respectively holds cutting ferrule of the equal interference fit of outer surface to extract from nylon tube to stop a corresponding end nut, each end of nylon tube is equipped with a hollow columnar lining, the internal surface interference fit of the corresponding end of sleeve outer surface and nylon tube, and lining one end is provided with for the annular protrusion of being close to the end face of a corresponding end; Sleeve outer surface is provided with the anti-pawl of extracting.
After adopting said structure, the utility model compared with prior art has the following advantages: owing to be provided with the lining of said structure, so the nylon tube end subsides can prevent that cutting ferrule from tightening up the time.
As improvement, described lining is copper bush, and the trade mark of the copper material that copper bush adopts is H62Y2, because the copper bush quality of described copper material is neither too hard, nor too soft, makes and the utility model both assemblings easily when producing can not cause damage to nylon tube again.
As improvement, described pawl has two circles, and through test, two number of turns amounts are the most suitable, both simplify the structure, and realized the requirement that is connected firmly again.
