Description

Physiosis axle

Technical Field

The utility model belongs to machine parts especially involves an physiosis axle.

Background

The inflatable shaft is a specially-made winding and unwinding shaft, namely a shaft with a protruded surface after high-pressure inflation and a shaft with a quickly retracted surface part after deflation, the separation and placement of the inflatable shaft and a paper tube (similar to a tubular product) can complete inflation and deflation within 3 seconds, and any part at the end side of the shaft does not need to be loosened to be tightly meshed with the paper tube;

as shown in fig. 1, the inner wall of the paper tube 1 is adsorbed to the air gap 3 of the air expansion shaft 2 due to inflation, and when the air is rapidly released, the air gap 3 of the outer wall of the air expansion shaft cannot be rapidly separated from the tube wall due to the vacuum state between the inner wall of the paper tube 1 and the air gap 3, so that the rotation or stop of the paper tube is delayed, and the size of the paper separated from the paper tube is not accurate.

SUMMERY OF THE UTILITY MODEL

The utility model provides an physiosis axle, the above-mentioned problem of solution.

In order to solve the above problem, the utility model provides a technical scheme as follows: an inflatable shaft comprises an inflatable shaft body, wherein an air filtering piece is arranged between an air seam on the body and an air port of an air pipe in the body, and the air filtering piece is provided with a groove body, a filter screen and a foamed plastic polymer; the filter screen is installed on the upper surface of the tank body, the foamed plastic polymer is placed in the groove of the tank body, and an air hole is formed in the bottom of the tank body and is in sealing fit with the air port.

Preferably, the upper surface of the groove body and the upper surface of the air seam are on the same horizontal plane; the lower surface and the lower surface of the air seam opening are in the same horizontal plane, and gaps between two sides of the groove body and two sides of the air seam opening are filled and sealed by fillers.

Preferably, the foamed plastic polymer is a sponge; an elastic piece is arranged inside the sponge.

Preferably, the thickness of the corresponding two side parts of the air seam opening is consistent with that of the groove body.

The beneficial effects for prior art are that, adopt above-mentioned scheme, the utility model provides a when the physiosis axle is deflated, because of the previous absorption of the gas seam mouth of paper pipe wall and physiosis axle, cause the vacuum state, at quick gassing, the pipe wall can't break away from the outer wall problem of physiosis axle fast to reduce the delay that the paper tube rotated or stopped.

Detailed Description

In order to facilitate understanding of the present invention, the present invention will be described in more detail with reference to the accompanying drawings and specific embodiments. Preferred embodiments of the present invention are shown in the drawings. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The use of the terms "fixed," "integrally formed," "left," "right," and the like in this specification is for illustrative purposes only, and elements having similar structures are designated by the same reference numerals in the figures.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

As shown in fig. 1-3, one embodiment of the present invention is: an inflatable shaft comprises an inflatable shaft body 2, wherein an air filtering piece is arranged between an air gap 3 in the body 2 and an air port 5 of an air pipe 4 in the inflatable shaft, and the air filtering piece is provided with a groove body 6, a filter screen 7 and a foamed plastic polymer 8; the upper surface mounting of cell body 6 filter screen 7, the recess of cell body 6 is placed foamed plastic polymer 8, the bottom of cell body 7 is equipped with air cavity 9, air cavity 9 with the sealed laminating of gas port 5.

Preferably, the upper surface of the groove body 6 and the upper surface of the air slit opening 3 are on the same horizontal plane; the lower surface of the groove body 6 and the lower surface of the air seam opening 3 are on the same horizontal plane, and gaps between two sides of the groove body 6 and two sides of the air seam opening 3 are filled and sealed by fillers.

Preferably, the foamed plastic polymer 8 is a sponge; the inside of sponge is equipped with the elastic component, and further, the elastic component is one end and filter screen 7 fixed connection, and the elastic component other end is fixed in the bottom of cavernosum or the lower top layer of cell body.

Further, the elastic component is a rubber column or a spring-like product formed by rubber materials, the interior of the rubber column is hollow, and a spring is arranged in the rubber column.

Preferably, the thickness of the corresponding two side parts of the air gap 3 is consistent with that of the groove body 6.

And (3) an air suction state:

when air is sucked, the air passes through the air port 5 of the air pipe, the air hole 9 of the groove body, the foamed plastic polymer 8 (sponge) and the filter screen, so that the air port 5 is adsorbed on the inner wall of the paper pipe 1, and the paper pipe stops rotating;

an air release state:

during deflation, the foamed plastic polymer 8 similar to sponge is arranged between the air port 5 and the inner wall of the paper tube 1, and according to the characteristics and the fluid mechanics principle of the sponge, the atmospheric pressure formed between the air port 5 and the inner wall of the paper tube 1 is not larger than the natural atmospheric pressure, so that the separation can be fast.

Further, the paper tube 1 can be separated from the air port 5 more quickly by the elastic member inside the sponge.

The beneficial effects for prior art are that, adopt above-mentioned scheme, the utility model provides a when the physiosis axle is deflated, because of the previous absorption of the air seam mouth of 1 wall of paper tube and physiosis axle 2, quick gassing causes the unable outer wall problem that breaks away from the physiosis axle fast of pipe wall to reduce the delay that the paper tube rotated or stopped.
