Abstract
The utility model provides an inserted connection type liquid pipeline connection pipe comprising a metal supporting pipe and a vulcanized rubber layer located on the outer side of the metal supporting pipe, wherein the whole connection pipe has enough rigidity through the metal supporting pipe; the metal supporting pipe and the vulcanized rubber layer are formed in a vulcanization mode, and thus the vulcanized rubber layer does not fall off easily in the using process. The two ends of the outer side face of the vulcanized rubber layer are respectively provided with a circle of rubber lip, the inner side faces of liquid conveying pipes connected with the two ends of the vulcanized rubber layer are provided with locating lips matched with the rubber lips in shape, and the rubber lips and the locating lips are in interference fit. By means of the connection structure, on the premise of ensuring the sealing performance, the connection pipe can be prevented from disengaging out, the sealing performance of the connection pipe is good, and the phenomenon that due to insufficient sealing and tearing of a rubber hose in the prior art, liquid in an engine leaks is avoided effectively. When connection and installation are carried out, the two ends of the connection pipe are inserted into the liquid conveying pipes needing connecting, and the connection pipe is simple in structure and convenient to install.
Description
Technical field
The utility model relates to a kind of plug-in type liquid line connecting tube, belongs to heavy-duty car technical field, for the connection of engine of heavy-duty car liquid line.
Background technique
At present, the metal liquid delivery pipes such as engine cooling liquid pipeline, lubricating oil pipeline, when connecting, generally adopt rubber hose to connect, and by clip, to rubber hose and liquid delivery tube, install fixing.Adopt after this linkage structure, its connection is comparatively complicated, simultaneously, due to the clip clamping force inequality that may exist, and easily loosening, therefore there will be situation poorly sealed between rubber hose and liquid delivery tube, thereby cause occurring the phenomenon of motor leakage.In addition, tearing also easily appears at clip place in rubber hose, also can cause occurring the phenomenon of motor leakage, and above phenomenon heavy-duty car uses and brings certain potential safety hazard and economic loss, the existing deficiency of prior art that Here it is.
Model utility content
The technical problems to be solved in the utility model, is exactly for the existing deficiency of prior art, and provides a kind of easy for installation, and the plug-in type liquid line connecting tube that connection sealing can be good.
This programme is achieved by the following technical measures: this plug-in type liquid line connecting tube comprises metallic support pipe and is positioned at the vulcanized rubber layer in metallic support pipe outside, metallic support pipe and vulcanized rubber layer pass through sulfidization molding, the two ends of described vulcanized rubber layer outer side surface arrange respectively a circle rubber lip, the inner side surface of the liquid delivery tube being connected with the two ends of vulcanized rubber layer is provided with the location lip with rubber lip form fit, and rubber lip is interference fit with location lip.
Above-mentioned rubber lip and vulcanized rubber layer are sulfuration integrated formed structure, and its overall performance is good, and in use rubber lip difficult drop-off, to guarantee the sealability of this connecting tube.
In order to guarantee support strength, the steel pipe that above-mentioned metallic support pipe preferably adopts No. 15, No. 20 or Q235 low-carbon steel material is made.
Vulcanized rubber layer can be according to carrying the kind of liquid and the difference of working environment to select flexibly, specifically, if while connecting oil circuit, the rubber layer that above-mentioned vulcanized rubber layer selects fluorine rubber material to make, if while connecting water route, rubber layer that above-mentioned vulcanized rubber layer selects ethylene propylene diene monomer (EPDM) material to make, thereby the cycle of the product development of having shortened, reduced the cost of exploitation.
The beneficial effect of this programme can be learnt according to the narration to such scheme, in this plug-in type liquid line connecting tube, by metallic support pipe, guarantee that connecting tube entirety has enough rigidity, metallic support pipe and vulcanized rubber layer, by sulfidization molding, guarantee in use difficult drop-off of vulcanized rubber layer.The two ends of vulcanized rubber layer outer side surface arrange respectively a circle rubber lip, the inner side surface of the liquid delivery tube being connected with the two ends of vulcanized rubber layer is provided with the location lip with rubber lip form fit, rubber lip is interference fit with location lip, this linkage structure is guaranteeing under the prerequisite of sealability, can also prevent that connecting tube from deviating from, its good seal performance, has effectively avoided because of poorly sealed and rubber hose, tearing in prior art the phenomenon of the motor leakage that causes.In addition, when carrying out connection, the two ends of this connecting tube are inserted respectively in the liquid delivery tube that needs to connect, it is simple in structure, easy for installation.As can be seen here, the utility model compared with prior art, has substantive distinguishing features and progress, and the beneficial effect of its enforcement is also apparent.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is and the partial structurtes schematic diagram of the liquid delivery tube that in the utility model, plug-in type liquid line connecting tube is connected.
In figure, 1-rubber lip, 2-metallic support pipe, 3-vulcanized rubber layer, 4-locates lip, 5-liquid delivery tube.
Embodiment
For clearly demonstrating the technical characterstic of this programme, below by embodiment, and in conjunction with its accompanying drawing, this programme is set forth.
A kind of plug-in type liquid line connecting tube, as shown in the figure, it comprises metallic support pipe 2 and is positioned at the vulcanized rubber layer 3 in metallic support pipe 2 outsides, the steel pipe that metallic support pipe 2 preferably No. 15, No. 20 or the machining of Q235 low-carbon steel material are made, metallic support pipe 2 becomes composite structure with vulcanized rubber layer 3 by sulfidization molding processes.The two ends of vulcanized rubber layer 3 outer side surface arrange respectively a circle rubber lip 1, and this rubber lip 1 is sulfuration integrated formed structure with vulcanized rubber layer 3.The inner side surface of the liquid delivery tube 5 being connected with the two ends of vulcanized rubber layer 3 is provided with the location lip 4 with rubber lip 1 form fit, and rubber lip 1 is interference fit with location lip 4.
During assembling, insert respectively in the liquid delivery tube 5 that needs to connect at the two ends of this connecting tube, and location lip 4 interference fit of rubber lip 1 and liquid delivery tube 5 internal surfaces, reach the object of sealing, and can not make this connecting tube and liquid delivery tube 5 depart from.Metallic support pipe 2 supports for vulcanized rubber layer 3 provides enough rigidity, guarantees the connective stability of this connecting tube.This connecting tube can, according to the structure difference of connected liquid delivery tube 5, regulate himself length and diameter, to adapt to the difference needs of liquid delivery tube 5.
In the utility model, without the technical characteristics of describing, can pass through or adopt existing techniques in realizing; do not repeat them here; certainly; above-mentioned explanation is not to restriction of the present utility model; the utility model is also not limited in above-mentioned mode of execution; variation, remodeling, interpolation or replacement that those of ordinary skill in the art makes in essential scope of the present utility model, also should belong to protection domain of the present utility model.
