Abstract

The utility model relates to a novel water pipe connection structure of a diesel engine. The novel water pipe connection structure of the diesel engine comprises a thermostat and a water outlet pipe, and further comprises a telescopic pipe composed of a circular metal framework and a rubber layer wrapping the outer surface of the metal framework, wherein the left end and the right end of the rubber layer are respectively provided with a rubber flange outwards protruding in the circumferential direction; the thermostat is internally provided with a thermostat connection hole; the water outlet pipe is internally provided with a water outlet pipe connection hole. Due to the fact that the telescopic pipe is connected with the thermostat and the water outlet pipe in an interference fit mode and the rubber flanges have the elasticity, the rubber flanges play a role in sealing after being clamped into the thermostat connection hole and the water outlet pipe connection hole. Compared with a traditional connection mode of a rubber pipe and a hoop, the sealing performance and the assembly efficiency are improved. Due to the fact that the metal framework inside the telescopic pipe is made of metal, compared with a traditional rubber pipe, the rubber pipe is better in pressure resistance, and it is effectively avoided that as the traditional rubber pipe can not resist pressure and cracks, accidents of water leakage and machine halt are caused.

Description

A kind of Novel diesel engine water pipe connecting structure
Technical field
The utility model relates to Diesel Engine Technique Field, is specifically related to a kind of diesel engine water pipe connecting structure.
Background technique
The mode of structure that often adopts rubber pipe to add clip between the thermostat casing of the diesel engine of now producing and outlet pipe connects; which exists assembling to connect complexity and the poor problem of sealing effect; and because the water in thermostat casing and outlet pipe exists certain pressure; often occurring that rubber pipe is unable to born presses and explosion, thereby causes leaking even the accident of shutting down.
Summary of the invention
The utility model is in order to overcome the deficiency of above technology, provides that a kind of efficiency of assembling is high, the diesel engine water pipe connecting structure of good airproof performance.
The utility model overcomes the technological scheme that its technical problem adopts:
This Novel diesel engine water pipe connecting structure, comprise thermostat and outlet pipe, also comprise by the metal frame of ring and be wrapped in the telescopic pipe that the rubber layer of metal frame outer surface forms, the two ends, left and right of described rubber layer are respectively arranged with the along the circumferential direction rubber flange of outwardly convex, in described thermostat, be provided with thermostat attachment hole, in described outlet pipe, be provided with outlet pipe attachment hole, the two ends of described telescopic pipe are installed in thermostat attachment hole and outlet pipe attachment hole by rubber flange interference respectively.
The beneficial effects of the utility model are: owing to adopting telescopic pipe to connect thermostat and outlet pipe by interference fit, and rubber flange has elasticity, after it snaps in thermostat attachment hole and outlet pipe attachment hole, plays seal action.Add the Placement of clip with respect to traditional rubber pipe, improved sealing and efficiency of assembling.And because the metal frame of telescopic pipe inside is made of metal, its withstand voltage properties for traditional rubber pipe is good, effectively avoids traditional rubber pipe to unable to bear to crush and splits, the accident of shutting down that causes leaking occurs.
Brief description of the drawings
Fig. 1 is linkage structure schematic diagram of the present utility model;
Fig. 2 is telescopic pipe position cross-sectional view;
Fig. 3 is thermostat position cross-sectional view;
Fig. 4 is outlet pipe position cross-sectional view;
In figure, the 1. outer 3. outlet pipe 4. thermostat attachment hole 5. outlet pipe attachment holes of telescopic pipe 1.1 metal frame 1.2 rubber layer 1.3 rubber flange 2. thermostats.
Embodiment
Below in conjunction with accompanying drawing 1, accompanying drawing 2, accompanying drawing 3, accompanying drawing 4, the utility model is described further.
This Novel diesel engine water pipe connecting structure, comprise thermostat 2 and outlet pipe 3, also comprise by the metal frame 1.1 of ring and be wrapped in the telescopic pipe 1 that the rubber layer 1.2 of metal frame 1.1 outer surfaces forms, the two ends, left and right of rubber layer 1.2 are respectively arranged with the along the circumferential direction rubber flange 1.3 of outwardly convex, in thermostat 2, be provided with thermostat attachment hole 4, in outlet pipe 3, be provided with outlet pipe attachment hole 5, the two ends of telescopic pipe 1 are installed in thermostat attachment hole 4 and outlet pipe attachment hole 5 by rubber flange 1.3 interference respectively.Owing to adopting telescopic pipe 1 to connect thermostat 2 and outlet pipe 3 by interference fit, and rubber flange 1.3 has elasticity, after it snaps in thermostat attachment hole 4 and outlet pipe attachment hole 5, plays seal action.Add the Placement of clip with respect to traditional rubber pipe, improved sealing and efficiency of assembling.And because the metal frame 1.1 of telescopic pipe 1 inside is made of metal, its withstand voltage properties for traditional rubber pipe is good, effectively avoids traditional rubber pipe to unable to bear to crush and splits, the accident of shutting down that causes leaking occurs.
