Abstract

A self-locking tube connecting structure comprises an inserting tube connector and an adapting tube connector, wherein the inserting tube connector is inserted into the adapting tube connector, an outer convex structure is arranged on the outer surface of the inserting tube connector, an inner convex structure is arranged on the inner wall of the adapting tube connector, convex degree of the outer convex structure and convex degree of the inner convex structure can reach the purpose that the inner convex structure and the outer convex structure can abut against opposite positions where the inserting tube connector and the adapting tube connector are locked in the axial direction. The self-locking tube connecting structure has the advantages of being simple in structure, easy to manufacture, convenient and quick to install and the like.

Description

A kind of self-locking pipe connecting structure
Technical field
The utility model relates to a kind of pipe connecting structure, particularly a kind ofly prevents from managing the self-locking pipe connecting structure that the joint comes off.
Background technique
Now pipe connecting structure uses that flange connects, being threaded is connected with the joint interference fit more, but these Placements existent defect all: the flange connection needs bolton, wastes time and energy; The screw thread processing cost that is threaded is high; Joint interference fit dismounting difficulty.
Summary of the invention
The characteristics such as the utility model provides a kind of self-locking pipe connecting structure, has easy processing, and is easy for installation, quick.
In order to solve the problems of the technologies described above, the utility model is taked following technological scheme:
A kind of self-locking pipe connecting structure comprises Inserting Tube joint and socket pipe joint, and the Inserting Tube joint inserts in the socket pipe joint.The outer surface of described Inserting Tube joint is provided with the outer lug structure, and socket pipe plug inwall is provided with the internal projection structure, the projection amount of inside and outside protruding structure for can mutually prop up pin Inserting Tube joint and socket pipe joint shaft to relative position.
Described inside and outside protruding structure arranges one or multi-channel.
Described internal projection structure is annular projection or point-like projection.
Described outer lug structure is annular projection or point-like projection.
Described Inserting Tube joint outer surface is provided with thrust ring, and this thrust ring is against socket pipe joint end face.
The endoporus of described socket pipe joint is shoulder hole, and the shoulder of shoulder hole is against the end face of Inserting Tube joint.
Described inside and outside protruding structure is plastic parts.
The utility model pins Inserting Tube joint and socket pipe joint relative position in the axial direction by inside and outside protruding structure is set, and makes the Inserting Tube joint can not come off from the socket pipe joint, and this linkage structure is simple, produces easily, and is easy for installation, quick.
Description of drawings
Fig. 1 is the utility model complete section structural representation.
Number in the figure is depicted as: 1-Inserting Tube joint, 2-socket pipe joint, 3-outer lug structure, 4-internal projection structure, 5-thrust ring, the shoulder of 6-shoulder hole.
Embodiment
For the ease of those skilled in the art's understanding, the utility model will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of self-locking pipe connecting structure comprises Inserting Tube joint 1 and socket pipe joint 2, and Inserting Tube joint 1 inserts in socket pipe joint 2.The outer surface of Inserting Tube joint 1 is provided with outer lug structure 3, and socket pipe plug 2 inwalls are provided with internal projection structure 4, and the projection amount of inside and outside protruding structure is for pinning the axial relative position of Inserting Tube joint 1 and socket pipe joint 2.Inside and outside protruding structure is equipped with one or multi-channel, is plastic parts.Outer lug structure 3 is annular projection or point-like projection, and internal projection structure 4 is annular projection or point-like projection.Inserting Tube joint 1 outer surface is provided with thrust ring 5, and this thrust ring 5 is against socket pipe joint end face.The endoporus of socket pipe joint 2 is shoulder hole, and the shoulder 6 of shoulder hole is against the end face of Inserting Tube joint.
When Inserting Tube joint 1 inserts socket pipe joint 2, internal projection structure 4 and outer lug structure 3 prop up the insertion that stops Inserting Tube joint 1 mutually, utilize and carry forward vigorously, inside and outside projection can produce resiliently deformable, Inserting Tube joint 1 is inserted in socket pipe joint 2, this moment, inside and outside protruding structure oppositely propped up, and pinned Inserting Tube joint 1 and the axial relative position of socket pipe joint 2.
Above-described embodiment is the better implementation of the utility model, and without departing from the concept of the premise utility, the replacement of just the utility model being made direct displacement or being equal to is within all belonging to protection domain of the present utility model.
