Description
Technical field
This utility model is related to pipe technology field and in particular to a kind of diesel engine oil-way assembling pipe joint.
Background technology
The mechanical field that is connected to of pipeline commonly uses, and especially in diesel engine oil pipeline, light pipe oil circuit is widely applied,
For such pipeline, the method adopting at present mainly has two kinds, and one is by welding, two sections of pipelines to be attached, this kind of result
It is irremovable and dismounting, once pipeline goes wrong, be difficult to problem is solved, and weld and also can make pipe deforming,
And then affect the circulation of channel interior fluid.Two is the union joint by using strip slip-collar, that is, pass through nut clip compressive strain
It is fixedly connected sealing, this is also pipeline connecting method more common at present, this connected mode one side clip price is held high
Expensive, be on the other hand exactly clip be disposable it is impossible to secondary use, and also occur that connection is tight once in a while, this
Sample will result in the problem of tube fluid leakage.
Utility model content
For solving above-mentioned technical problem, the purpose of this utility model is to propose a kind of diesel engine oil-way assembling pipe joint.
This utility model is to complete above-mentioned purpose to adopt the following technical scheme that：
A kind of diesel engine oil-way assembling pipe joint, described assembling pipe joint has in order to by two external pipes even
It is connected in the body connecting pipe road of one；Described body connecting pipe road is the cylinder of hollow structure；Outside body connecting pipe road
Footpath is less than the internal diameter of external pipe；The middle part of described body connecting pipe road periphery has external screw thread；Described body connecting pipe road
The two ends of periphery are respectively provided with circumferential groove, and described circumferential groove is the wedge shape being tilted to middle part from the two ends in body connecting pipe road,
Make body connecting pipe road two ends formed from body connecting pipe road cone table from center to two ends flaring footpath；Described circumferential groove
Inside it is provided with the elastic circular ring being nested with body connecting pipe road, and described elastic circular ring can connect along main body in circumferential groove
Slide in pipe centerline direction；Described elastic circular ring is split ring；The external diameter of described elastic circular ring is less than the interior of external diameter pipeline
Footpath；The nut threadeded with it is provided with the external screw thread in body connecting pipe road, described nut is two；Described elasticity
Annulus external pipe docking drawing when will swelling between the sphenoid in described external pipe and body connecting pipe road, make
External pipe is closely connected as one with body connecting pipe road, and by the nut threadeded with body connecting pipe road and extension tube attached
The port surface in road fits tightly.
The utility model proposes a kind of diesel engine oil-way assembling pipe joint, can accomplish processing technique more convenient,
The features such as swift to operate, easy to use, connection is tight, range is wide.

Specific embodiment
Accompanying drawings below and specific embodiment are illustrated to this utility model
As shown in Figure 4, Figure 5, a kind of diesel engine oil-way assembling pipe joint, described assembling pipe joint has in order to incite somebody to action
The body connecting pipe road 1 that two external pipes 4 connect as one；In conjunction with Fig. 1, Fig. 2, described body connecting pipe road 1 is hollow
The cylinder of structure；The external diameter in body connecting pipe road 1 is less than the internal diameter of external pipe 4；Described body connecting pipe road 1 periphery
Middle part has external screw thread 11；The two ends of described body connecting pipe road periphery are respectively provided with circumferential groove 12, and described circumferential groove 12 is served as reasons
The two ends in body connecting pipe road 1 tilt the wedge shape of certain angle to middle part, so that the two ends in body connecting pipe road 1 is formed by main body
The center of connecting pipe 1 is to the cone table in two ends flaring footpath；It is provided with described circumferential groove 12 and be nested with body connecting pipe road
On elastic circular ring 2, and described elastic circular ring 2 in circumferential groove along main center's line direction slide；In conjunction with Fig. 3, described
Elastic circular ring 2 is split ring；The external diameter of described elastic circular ring 2 is less than the internal diameter of external diameter pipeline；The external screw thread in body connecting pipe road
It is provided with the nut 3 threadeded with it, described nut 3 is two on 11；Described elastic circular ring 2 is right in external pipe 4
Connect during drawing will swelling between circumferential groove 12 sphenoid in described external pipe 4 and body connecting pipe road 1, make extension tube attached
Road 4 is closely connected as one with body connecting pipe road 1, then tightens nut 3 again, makes nut 3 tight with the port surface of external pipe 4
Closely connected conjunction, annulus 2 now will more swelling.
When carrying out external pipe and docking with oil line pipe attachment means, external pipe 4 Interposed portable pipeline connects dress
During putting, elastic circular ring 2 can slide to circumferential groove 12 depths, and external pipe 4 can stretch into oil line pipe attachment means
Suitable distance in body connecting pipe road 1, after stretching into suitable distance, draws external pipe 4, bullet to the port in body connecting pipe road 1
Property annulus 2 can circumferentially groove 12 slide in and out, in sliding process, due to the port spreading on elastic circular ring, and then make external
Pipeline 4 is completely embedded with body connecting pipe road 1 and is connected, and at this moment passes through the outer wall spiral shell nut 3 and body connecting pipe road 1 for the spanner again
Stricture of vagina 11 is tightened, and makes nut 3 be close to external pipe 4 port surface, so external pipe 4 can be made to be connected more with body connecting pipe road 1 again
Step up close.
