Description

Outer protective sleeve

Technical Field

The utility model relates to a hose protection technical field, concretely relates to outer protective sheath.

Background

The corrugation of the corrugated pipe such as the hose of the existing dust collector is exposed outside. When in use, not only the adjacent corrugations have friction with each other, but also the adjacent corrugations are easy to distort and deform to generate creases or even collapse, thereby influencing the ventilation or dust collection effect. In addition, after long-term use, the crease can not rebound, so that the bending and twisting performance of the corrugated pipe is reduced, and as a result, the corrugated pipe is broken, and the service life of the hose is shortened.

Disclosure of Invention

In order to solve the problems existing in the prior art, the utility model provides an outer protective sleeve.

The utility model provides a technical scheme of above-mentioned problem does: an outer protective sleeve comprises an outer shell, an inner shell, a buffer device, a ring plate and a protective sleeve joint;

the outer shell comprises a conical soft sleeve and a first hose, the front end of the conical soft sleeve is connected with the protective sleeve joint, the rear end of the conical soft sleeve is connected with the front end of the first hose, the rear end of the first hose is connected with the ring plate, and the diameter of the conical soft sleeve is gradually increased from outside to inside;

the inner shell comprises a conical pipe fitting and a first sleeve, the front end of the conical pipe fitting is connected with the protective sleeve joint, the rear end of the conical pipe fitting is connected with the front end of the first sleeve, the rear end of the first sleeve is connected with the annular plate, and the diameter of the conical pipe fitting is gradually increased from outside to inside;

a first cavity is formed between the first hose and the first sleeve, the buffer device is arranged in the first cavity and comprises a ring-shaped piece, a plurality of first springs and a plurality of second springs, the plurality of first springs are uniformly distributed between the first hose and the ring-shaped piece, the upper ends of the first springs are connected with the first hose, the lower ends of the first springs are connected with the ring-shaped piece, the plurality of second springs are uniformly distributed between the ring-shaped piece and the first sleeve, the upper ends of the second springs are connected with the ring-shaped piece, and the lower ends of the second springs are connected with the first sleeve;

a plurality of heat dissipation holes are formed in the inner shell and the outer shell.

The utility model discloses beneficial effect has:

the utility model comprises an outer shell and an inner shell, wherein the outer shell is a hose, which can reduce the abrasion of the protective sleeve to the external parts, a buffer device is arranged between the outer shell and the inner shell, when the outer shell is stressed, the first spring plays a buffer role, the first spring and the second spring are evenly arranged, so that the annular part and the inner shell are stressed evenly, and the first gasket and the second gasket can reduce the abrasion of the protective sleeve to the corrugated pipe; the utility model discloses simple structure, reasonable in design has prolonged the life of bellows.
