Technical field

The present invention relates to technical field of pipeline connection more particularly to a kind of gas-tpe fittings of elastic webbing anti-drop function.

Background technique

Existing gas-tpe fitting adopts thin spring card often to realize locking tracheae, and the coupling mechanism force that can be provided is small, is using It will appear the phenomenon that tracheae falls off in journey, after tracheae falls off, adjoint is exactly joint failure, while hidden with certain safety Suffer from.

Summary of the invention

To solve technical problem present in background technique, the present invention proposes that a kind of tracheae of elastic webbing anti-drop function connects Head.

The gas-tpe fitting of a kind of elastic webbing anti-drop function proposed by the present invention, comprising: joint body and anti-decylization；

It is equipped with tracheae installation passage in the middle part of joint body, tracheae installation passage one end is equipped with to be circular layout along inner wall Mounting groove, the direction in the mounting groove in the middle part of the radial tracheae installation passage are gradually reduced；

Anti-decylization has the C-shaped configuration of sidewall opening, and anti-decylization inner wall is equipped with anti-back tooth, and connector sheet is protruded into anti-decylization one end The mounting groove of body.

Preferably, anti-decylization inner wall is equipped with axially distributed multiple anti-back teeth.

Preferably, anti-back tooth wall circular along decylization extends.

Preferably, anti-decylization is equipped with insertion section close to joint body one end, and the outer radial of the insertion section is far from connector sheet The direction of body is gradually increased.

Preferably, the insertion site is in the mounting groove, and the outer wall of the insertion section and the mounting groove is interior Wall fitting.

It preferably, further include sealing ring, joint body inner wall is additionally provided with the mounting groove for accommodating sealing ring, sealing ring position In in the mounting groove.

Preferably, sealing ring and the tracheae installation passage are coaxially disposed.

Preferably, anti-decylization and the tracheae installation passage are coaxially disposed.

In the present invention, the gas-tpe fitting of the elastic webbing anti-drop function proposed, it is logical that joint body middle part is equipped with tracheae installation Road, tracheae installation passage one end are equipped with the mounting groove being circular layout along inner wall, the radial tracheae peace in the mounting groove The direction of dress channel middle is gradually reduced；Anti-decylization has the C-shaped configuration of sidewall opening, and anti-decylization inner wall is equipped with anti-back tooth, prevents The mounting groove of joint body is protruded into decylization one end.By the gas-tpe fitting of the elastic webbing anti-drop function of above-mentioned optimization design, The anti-decylization of joint body is designed as the C-shaped configuration that side wall has opening, when installation makes anti-decylization have certain deformation empty Between, joint body stings clamp force to tracheae application by anti-back tooth when use, to realize that tracheae stops to anti-decylization leave of absence pretightning force The effect moved back improves the reliability of tracheae and joint body installation.

Detailed description of the invention

Fig. 1 is a kind of structural schematic diagram of the gas-tpe fitting of elastic webbing anti-drop function proposed by the present invention.

Fig. 2 is a kind of structural schematic diagram of the anti-decylization of the gas-tpe fitting of elastic webbing anti-drop function proposed by the present invention.

Specific embodiment

As illustrated in fig. 1 and 2, Fig. 1 is a kind of structural representation of the gas-tpe fitting of elastic webbing anti-drop function proposed by the present invention Figure, Fig. 2 are a kind of structural schematic diagram of the anti-decylization of the gas-tpe fitting of elastic webbing anti-drop function proposed by the present invention.

Referring to Fig.1 with 2, a kind of gas-tpe fitting of elastic webbing anti-drop function proposed by the present invention, comprising: 1 He of joint body Anti-decylization 2；

Tracheae installation passage is equipped in the middle part of joint body 1, tracheae installation passage one end is equipped with and is circular layout along inner wall Mounting groove, the direction in the mounting groove in the middle part of the radial tracheae installation passage is gradually reduced；

Anti-decylization 2 has the C-shaped configuration of sidewall opening, and 2 inner wall of anti-decylization is equipped with anti-back tooth 21, and 2 one end of anti-decylization is protruded into The mounting groove of joint body 1.

In the specific installation process of the gas-tpe fitting of the elastic webbing anti-drop function of the present embodiment, by tracheae 10 from joint body 1 passes through tracheae installation passage far from mounting groove one end, and anti-decylization is mounted on gas by sidewall opening in the mounting groove side Outside pipe, anti-decylization one end is then pushed into mounting groove to joint body direction, as insertion process center tap ontology is to anticreep The radial compression power of ring increases, and anti-decylization is since deformation occurs for the presence of opening, so that anti-back tooth is circumferentially and outside tracheae Wall fitting, is realized to tracheae retaining.

In the present embodiment, the gas-tpe fitting of the elastic webbing anti-drop function proposed, joint body middle part are equipped with tracheae and pacify Channel is filled, tracheae installation passage one end is equipped with the mounting groove being circular layout along inner wall, the radial gas in the mounting groove Direction in the middle part of pipe installation passage is gradually reduced；Anti-decylization has the C-shaped configuration of sidewall opening, and anti-decylization inner wall is equipped with anti-back The mounting groove of joint body is protruded into tooth, anti-decylization one end.Pass through the tracheae of the elastic webbing anti-drop function of above-mentioned optimization design The anti-decylization of joint body is designed as the C-shaped configuration that side wall has opening by connector, and when installation makes anti-decylization have a setting Emptying, joint body stings clamp force to tracheae application by anti-back tooth when use, to realize gas to anti-decylization leave of absence pretightning force The effect of pipe retaining improves the reliability of tracheae and joint body installation.

In order to improve anticreep effect, in the specific embodiment of anti-decylization, 2 inner wall of anti-decylization is equipped with axially distributed Multiple anti-back teeth 21.

Further, in the specific design method of anti-back tooth, the wall circular along decylization of anti-back tooth 21 extends, and increases anticreep The circumferential contact area of ring and tracheae improves retaining effect.

In other specific embodiments of anti-decylization, anti-decylization 2 is equipped with insertion section close to 1 one end of joint body, described The outer radial of insertion section is gradually increased far from the direction of joint body, in further specific design method, the insertion site In in the mounting groove, and the outer wall of the insertion section is bonded with the inner wall of the mounting groove；Pass through anti-decylization insertion section outer wall With the cooperation of mounting groove inner wall, improve when installing to the uniformity of the extruding force of anti-decylization.

In the specific mounting means of anti-decylization, anti-decylization 2 and the tracheae installation passage are coaxially disposed, and guarantee anti-back tooth With inner surface of trachea installation reliability.

In other specific embodiments, the connector of the present embodiment further includes sealing ring 3, and 1 inner wall of joint body is additionally provided with For accommodating the mounting groove of sealing ring 3, sealing ring is located in the mounting groove；Anti-decylization and sealing ring cooperate, and guarantee installation knot The stability of structure and the reliability of sealing.

In the specific design method of sealing ring, sealing ring 3 and the tracheae installation passage are coaxially disposed.
