Abstract

The utility model discloses a metal hose convenient to install, and belongs to the field of metal hose application. After the small flange is inserted into the inner ring of the conveying pipeline, the clamping block on the small flange compresses the spring under the action of the inner wall of the conveying pipeline and enters the clamping block cavity, and meanwhile, the spring reacts on the clamping block to enable the clamping block to be tightly pressed on the inner wall of the conveying pipeline, so that the subsequent fixed installation of the conveying pipeline is facilitated, and the consumption of human resources is reduced.

Description

Metal collapsible tube convenient to installation

Technical Field

The utility model relates to the field of metal hose application, in particular to a metal hose convenient to install.

Background

The metal hose is used as a flexible pressure-resistant pipe fitting to be arranged in a conveying system of equipment, is used for compensating mutual displacement of a pipeline or a machine and equipment connecting end, absorbs vibration energy, can play roles in vibration reduction, noise reduction and the like, and has the characteristics of good flexibility, light weight, corrosion resistance, fatigue resistance, high and low temperature resistance and the like. During the installation process, the accuracy of installation can be ensured only by manually supporting the metal hose and keeping the joints at the two ends aligned.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a metal hose convenient to install.

The technical scheme of the utility model is as follows: the utility model provides a metal collapsible tube convenient to installation for connect pipeline, include the interior net cover that sets gradually from inside to outside, the bellows, the outer net cover, interior net cover, the bellows, the outer net cover passes through welded fastening with the connecting pipe that sets up at both ends and is connected, the port part and the supporting ring flange sealing connection of connecting pipe, the fixed small flange that is provided with of port part of ring flange, the external diameter of small flange and pipeline's internal diameter phase-match, small flange evenly distributed has a plurality of recess along outer wall circumference, every recess comprises the spring chamber that is used for the holding spring and the fixture block chamber that is used for the holding fixture block, the spring is fixed on recess inner wall through being close to one side of recess inner wall of fixture block.

According to a further technical scheme, the fixture block is of a conical structure, and the conical tip of the fixture block is arranged close to the end face of the small flange.

In a further technical scheme, the outer net sleeve consists of a plurality of metal wire net layers.

The utility model has the beneficial effects that:

after the small flange is inserted into the inner ring of the conveying pipeline, the clamping block on the small flange compresses the spring under the action of the inner wall of the conveying pipeline and enters the clamping block cavity, and meanwhile, the spring reacts on the clamping block to enable the clamping block to be tightly pressed on the inner wall of the conveying pipeline, so that the subsequent fixed installation of the conveying pipeline is facilitated, and the consumption of human resources is reduced.

Drawings

FIG. 1 is a schematic structural view of the present invention,

FIG. 2 is an enlarged view of the structure at A in FIG. 1,

the device comprises a base, a clamping block, a connecting pipe, a clamping block cavity, a clamping block, a spring cavity, a clamping block, a clamping ring, a connecting pipe, a clamping ring cavity, a clamping block, a clamping ring cavity, a clamping block, a clamping ring cavity, a clamping ring, a clamping block, a clamping ring and a clamping ring, wherein the clamping ring is arranged in the base.

Detailed Description

The utility model will be further illustrated and understood by the following non-limiting examples.

As shown in figures 1-2, the utility model provides a metal hose convenient to install, which is used for connecting a conveying pipeline and comprises an inner net sleeve 1, a corrugated pipe 2 and an outer net sleeve 3 which are sequentially arranged from inside to outside, wherein the outer net sleeve 3 consists of a plurality of metal wire net layers. Inner net cover 1, bellows 2, outer net cover 3 and the connecting pipe 4 that sets up at both ends pass through welded fastening and are connected, the port part of connecting pipe 4 and 5 sealing connection of supporting ring flange, the fixed little flange 6 that is provided with of port part of ring flange 5, the external diameter of little flange 6 and pipeline's internal diameter phase-match, little flange 6 evenly distributed has a plurality of recess along on the outer wall circumference, every recess comprises spring chamber 61 that is used for holding spring 63 and the fixture block chamber 62 that is used for holding fixture block 64, the fixture block 64 is close to one side of recess inner wall and is fixed on the recess inner wall through spring 63, and fixture block 64 is the toper structure, and the conical tip direction of fixture block 64 is close to the terminal surface setting of little flange 6.

After the small flange 6 is inserted into the inner ring of the conveying pipeline, the fixture block 64 on the small flange 6 enters the fixture block cavity 62 under the action of the inner wall of the conveying pipeline and compresses the spring 63, and meanwhile, the spring 63 reacts on the fixture block 64 to enable the fixture block 64 to be tightly pressed on the inner wall of the conveying pipeline, so that the subsequent fixed installation of the conveying pipeline is facilitated, and the consumption of human resources is reduced.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
