Description

PVC (polyvinyl chloride) bladder with novel air sleeve

Technical Field

The utility model relates to a PVC ball bladder technical field especially relates to a take PVC ball bladder of novel gas jacket.

Background

The bladder is a bladder for supporting balls, is of a hollow structure, and is mostly filled with gas. Most of the traditional ball bladders are made of rubber, but the traditional ball bladders have the problems of high cost and easy air leakage; at present, PVC (polyvinyl chloride) bladders are more common in the market, have low cost and are not easy to deform and leak. One side of the common PVC bladder is provided with an air nozzle for inflating and deflating, and the outside of the air nozzle is provided with an air sleeve; the air sleeve with the structure has poor air tightness, the air nozzle is easy to pull out, and air leakage is easy.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the defects existing in the prior art and providing a PVC bladder with a novel air sleeve.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a take PVC bladder of novel gas pocket, includes bladder body, threaded rod and bull stick, bladder body outer wall is equipped with puncture-proof layer, and bladder body inner wall connection has the sleeve pipe, the intraductal wall of sleeve is equipped with the internal thread, and the intraductal wall of sleeve is fixed with the sealing ring, the sealing ring inner wall bonds there is sealed the pad, and all articulates through the spring hinge at sealing ring bottom outer wall both ends has the apron.

Preferably, the outer wall of the top of the threaded rod is provided with a hexagonal groove, and the outer wall of the bottom of the threaded rod is fixed with a snap ring.

Preferably, the outer wall of the bottom of the rotating rod is fixedly provided with a hexagonal prism, and the hexagonal prism is matched with the hexagonal groove.

Preferably, the threaded rod is matched with the inner wall of the sleeve.

The beneficial effects of the utility model are that:

1. according to the PVC bladder, when the bladder body is impacted by an external sharp object through the arranged puncture-proof layer, the PVC bladder is not easy to damage and leak air, the service life of the bladder body is prolonged, the threaded rod can be screwed into the sleeve through the arranged internal thread to block the sleeve, the sleeve is not easy to fall off, and meanwhile, the clamping ring can be clamped on the sealing gasket to extrude the sealing gasket to block a gap between the threaded rod and the inner wall of the sleeve, so that the PVC bladder is better in sealing effect and does not leak air;

2. the PVC bladder of this design, when inflating to bladder body inside, the air current can strut the apron and get into the bladder originally internally, when gas is full of, when not needing to aerify, the apron is under the effect of spring hinge, and self-closing seals the sealing ring bottom, avoids the in-process air current of screw-in threaded rod wafting in toward the sleeve pipe, and the design is more humanized.
