Description

A kind of anticreep pipe joint

Technical field

This utility model is related to a kind of anticreep pipe joint.

Background technology

Operating temperature be -40-140 DEG C environment in, or pacify because of equipment design for conveying the rubber hose of refrigerating fluid , there is T-shaped or cross bifurcated and plug in reload request, actually used in many coordinate quick clip to realize 2 or many with snap joint Connection between individual rubber hose.After mainly using quick clip banding rubber hose and snap joint, rubber hose with fast Frictional force between quick coupling is offsetting the slippage power of rubber hose.Under normal temperature state, (20 DEG C), equipment (rubber hose) is no Can be very good to keep compactness and resistance to leakage in the case of fluid power impact in vibration, sebific duct；Once in high temperature (low temperature), height Under vibration, the working environment of high fluid power impact, easily because deform being used for of leading to of rubber hose fixes rubber hose and gold There is relative movement in the clip (duplex clip) belonging to joint, ultimately result in pipeline leakage, or even rubber hose and pipe joint Situation about slipping.

One of solution universal at present is to be plugged into rubber hose using fast method, and the most frequently used is just to increase interference Design, but this can lead to installation process labor intensity to increase it is also possible to be damaged to the hose lining of rubber hose in installation process, Increase the risk revealed.

Another kind of method is that rubber hose is connected by the way of being permanently fixed with pipe joint, and such as screw thread is connected, but this increasing Add length of pipe and installing space, be difficult with the occasion of narrow space；And using the threaded cost of directly resulting in Increase (8-15 times can be increased).

From the aspect of cost, installation, processing, cost etc., in narrow space, operation is limited, apply operating mode more severe In the case of, need to design the more practical and more preferable connecting device of the suitability.

Content of the invention

For overcoming drawbacks described above, this utility model provides a kind of anticreep pipe joint.

The technical solution of the utility model is：

A kind of anticreep pipe joint, including pipe joint body, pipe joint body is provided with several and is used for and pipeline to be connected The union joint of connection, also includes several clips combination for fixed connector and pipeline to be connected, and clip combination is set in On union joint, and there is gap between clip combination inwall and union joint outer wall, to install pipeline to be connected,

Described clip combination includes several clips be arrangeding in parallel, and in the combination of each clip, adjacent clip is all by even Fitting is fixedly linked；And connector one end is horizontal-extending to pipe joint body, and pipe joint body is fixed on by fixing device On；

Further, described fixing device includes screw and the screw being opened in connector one end, and described screw passes through described Screw, and connector is tightened on pipe joint body.

Further, described connector is in strip.

Further, clip combination includes 2 clips being coaxially disposed.

Further, described connector and the outside wall surface of clip are welded and fixed.

Further, described pipeline to be connected is rubber hose.

The beneficial effects of the utility model are：

(1) using screw, clip is fixed on pipe joint body, clip is consolidated in the axial location of pipe joint body Fixed, relative movement is less likely to occur clip；And clip is combined together with rubber hose, union joint, pipe joint body, it is right to increased The restraining forceies of rubber hose, when rubber hose because the reasons such as temperature change, vibrations, fluid power impact occur elastic physical property increase, phase When increasing to wriggling, clip can constrain rubber hose well, and still can keep between rubber hose inner surface and union joint Good contact and active force, are effectively reduced the generation of leakage and slippage accident.

(2) have that structure is simple, be easy to operation, the features such as structural stability is good, being readily adapted for limited space, stability will Height, integral device is asked to have vibrations, internal fluid power to have in the environment of impact.

Specific embodiment

As illustrated, a kind of anticreep pipe joint, including pipe joint body 1, pipe joint body 1 be provided with several for The union joint 5 of pipeline communication to be connected, pipe joint body 1 connects pipeline to be connected by union joint 5, also includes connecting for fixing Several clips combination of joint 5 and pipeline to be connected, clip combination is set on union joint 5, and clip combination inwall and company There is gap, to install pipeline to be connected between joint 5 outer wall；

Described clip combination includes several clips 2 be arrangeding in parallel, and in the combination of each clip, adjacent clip 2 all passes through Connector 3 is fixedly linked；And connector 3 one end is horizontal-extending to pipe joint body 1, and pipe joint is fixed on by fixing device On body 1；

Described fixing device includes screw and the screw 4 being opened in connector 3 one end, and described screw 4 passes through described screw, And connector 3 is tightened on pipe joint body 1, clip combination is fixed on pipe joint body 1, limits clip 2 and treating When connecting pipe is wriggled, there is the displacement with respect to pipeline to be connected and union joint 5.

Described connector 3 is in strip.

Clip combination includes 2 clips 2 being coaxially disposed.

Described connector 3 is welded and fixed with the outside wall surface of clip 2.

Described pipeline to be connected is rubber hose.

Using screw 4, clip 2 is fixed on pipe joint body 1, clip 2 obtains in the axial location of pipe joint body 1 Fixing, relative movement is less likely to occur clip 2；And clip 2 is combined together with rubber hose, union joint 5, pipe joint body 1, rubber Between glue hose inner wall and union joint 5 frictional force, the frictional force between clip inwall and rubber hose outer wall offsets jointly The pulling-out force of rubber hose, increased the restraining forceies to rubber hose, when rubber hose is because of temperature change, vibrations, fluid power impact When occurring elastic physical property increase, relative creep to increase etc. reason, clip 2 can constrain rubber hose well, and in rubber hose Good contact and active force still can be kept between surface and union joint 5, be effectively reduced the generation of leakage and slippage accident.

In the prior art, the tightening force of clip is mainly used in constraining the prestressing force of rubber hose and union joint contact surface, Ensure to be in close contact between rubber hose inner surface and union joint outside wall surface；Clip 2 of the present utility model and union joint 5 are possessing On the premise of above-mentioned functions, because clip 2 and pipe joint body 1 be rigidly connected it is ensured that clip 2 internal face and rubber hose outer Surface has enough frictional force, increases the constraint to rubber hose further, can effectively reduce slippage；But in structure originally Utility model has simple, flexible, install convenient, the low feature to environmental requirement like the prior art.

Content described in this specification embodiment is only enumerating of the way of realization to utility model design, and this practicality is new The protection domain of type is not construed as being only limitted to the concrete form that embodiment is stated, protection domain of the present utility model also wraps Include those skilled in the art according to this utility model design it is conceivable that equivalent technologies mean.
