Abstract

The utility model discloses a corrugated pipe joint, which comprises a joint body and a lock sleeve sleeved in the joint body, wherein at least two elastic lock hooks are circumferentially arranged on the lock sleeve and are matched with a groove of the outer side wall of a corrugated pipe sleeved in the lock sleeve; the matching surface on the inner side wall of the connector body, which is matched with the lock hook, is inclined along the radial direction; when the lock sleeve moves along one end of the connector body, the matching surface presses one end of the lock hook, and the other end of the lock hook bounces towards the outer side of the lock sleeve and is separated from the groove in the outer side wall of the corrugated pipe; when the corrugated pipe needs to be pulled out of the connector, the lock sleeve is only required to be pushed towards one end of the connector body, and the elastic lock hook is matched with a matching surface on the connector body to bounce outside the lock sleeve, so that the lock hook is separated from the groove on the outer side wall of the corrugated pipe; at the moment, the corrugated pipe can be pulled out along one end of the connector body, so that the corrugated pipe can be pulled out quickly, the structure is simple, the use is convenient, and the operation time is saved.

Description

Corrugated pipe joint

Technical Field

The utility model relates to a pipe connection technical field, concretely relates to bellows joint.

Background

The corrugated pipe is a tubular elastic sensitive element formed by connecting foldable corrugated sheets along the folding and stretching direction, is widely applied in instruments and meters, and is mainly used as a measuring element of a pressure measuring instrument to convert pressure into displacement or force; in actual use, the corrugated pipe needs to be connected with a connector through a connecting joint; the existing corrugated pipe connector has the problems that after the existing corrugated pipe connector is connected with a corrugated pipe, the existing corrugated pipe connector is not easy to pull out and is inconvenient to use.

SUMMERY OF THE UTILITY MODEL

To the not enough of prior art existence, the utility model aims to provide a corrugated pipe joint.

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

a corrugated pipe joint comprises a joint body and a lock sleeve sleeved in the joint body, wherein at least two elastic lock hooks are circumferentially arranged on the lock sleeve and are matched with a groove in the outer side wall of a corrugated pipe sleeved in the lock sleeve;

the matching surface on the inner side wall of the connector body, which is matched with the lock hook, is inclined along the radial direction;

when the lock sleeve moves along one end of the connector body, one end of the lock hook is extruded by the matching surface, and the other end of the lock hook bounces towards the outer side of the lock sleeve and is separated from the groove in the outer side wall of the corrugated pipe.

The utility model discloses further set up: the outer side of the lock hook is provided with a limiting part, and the joint body is provided with a limiting hole matched with the limiting part.

The utility model discloses beneficial effect: inserting the corrugated pipe into a lock hook, wherein the lock hook is matched with a groove on the outer side wall of the corrugated pipe, and fixing the corrugated pipe in the lock hook; when the corrugated pipe needs to be pulled out of the connector, the lock sleeve is only required to be pushed towards one end of the connector body, and the elastic lock hook is matched with a matching surface on the connector body to bounce outside the lock sleeve, so that the lock hook is separated from the groove on the outer side wall of the corrugated pipe; at the moment, the corrugated pipe can be pulled out along one end of the connector body, so that the corrugated pipe can be pulled out quickly, the use is convenient, and the operation time is saved.

Fig. 1 is an exploded view of a bellows joint according to the present invention;

description of reference numerals: 1. a connector body; 11. a mating surface; 12. a limiting hole; 2. a lock sleeve; 21. a latch hook; 22. a limiting part.

Detailed Description

An embodiment of a bellows joint according to the present invention is described in further detail with reference to fig. 1.

A corrugated pipe joint comprises a joint body 1 and a lock sleeve 2 sleeved in the joint body 1, wherein at least two elastic lock hooks 21 are circumferentially arranged on the lock sleeve 2, and the lock hooks 21 are matched with grooves on the outer side wall of a corrugated pipe sleeved in the lock sleeve 2; inserting the corrugated pipe into the lock sleeve 2, wherein the lock hook 21 is matched with a groove on the outer side wall of the corrugated pipe, and the corrugated pipe is fixed in the lock sleeve 2;

the matching surface 11 matched with the lock hook 21 on the inner side wall of the connector body 1 is inclined along the radial direction, so that the aperture matched with the lock hook 21 on the inner side of the connector body 1 is gradually reduced along the sleeving direction of the lock sleeve 2;

when the lock sleeve 2 moves along one end of the connector body 1, the matching surface 11 presses one end of the lock hook 21, and the other end of the lock hook 21 bounces towards the outer side of the lock sleeve 2 and is separated from the groove in the outer side wall of the corrugated pipe.

When the corrugated pipe needs to be pulled out of the connector, the lock sleeve 2 is only required to be pushed towards one end of the connector body 1, and the elastic lock hook 21 is matched with the matching surface 11 on the connector body 1 to bounce outside the lock sleeve 2, so that the lock hook 21 is separated from the groove on the outer side wall of the corrugated pipe; at the moment, the corrugated pipe can be pulled out along one end of the connector body 1, the corrugated pipe is pulled out quickly, the structure is simple, the use is convenient, and the operation time is saved.

The outer side of the lock hook 21 is provided with a limiting part 22, and the joint body 1 is provided with a limiting hole 12 matched with the limiting part 22; the bellows is restricted from rotating within the fitting body 1.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
