Abstract
The invention provides a fast connecting pipeline without a thread, consisting of a pipe head, a connecting pipe, a pipe clamp and a sealing ring; the external side of the pipe head is provided with a sealing concave trough, a positioning platform and a position limit ring; the connecting pipe is sheathed on the connecting end of the pipe head so as to form a matching connection pair; the external side of the connecting pipe is provided with a circumference positioning concave trough; the pipe clamp is formed by connecting a positioning clamping ring and a release clamping ring through two symmetrical connecting belts; the positioning clamping ring is sheathed on the positioning platform of the pipe head and forms a matching and position limiting connection through the position limit platform; the release clamping ring is an ellipse; the internal side of a short shaft is provided with a block button which forms a connection pair by matching with the positioning concave trough at the external circumference of the connecting pipe; a long shaft end is a pressing release part; the short shaft end is opened outwards and disconnected from the circumference positioning concave trough of the connecting pipe when the long shaft end is pressed inwards. The pipe clamp is taken as a connection mechanism, therefore the pipe head and the connecting pipe can be fast connected and fixed; the invention has the advantages of fast disassembly and assembly, good sealing performance, oil resistance, high strength, etc. The invention overcomes the shortages of complex processing and inconvenient disassembly and assembly, etc. of the connection type of the existing pipeline thread.
Description
Technical field
The present invention discloses a kind of non-screw thread quick-connecting pipe fitting, is to the improvement of existing pipe connecting device structure, belongs to pipeline mechanical parts technical field.
Technical background
Conventional stereoplasm tube pipe connecting connects general the employing and is threaded or the flange Connecting format.Manufacturing firm all needs this one procedure of machining screw when producing all kinds of pipeline connecting parts; And the user also needs with special tool pipe to be carried out screw thread processing when connecting pipeline, also will twine sealing material when connecting.Therefore, this pipeline connecting parts, concerning factory, complex process, work efficiency is low; Concerning the user, need special device, mounting or dismounting are complicated, and labor intensity is big, in addition, because screw thread has been twisted in the pipe termination, tube wall strength is reduced.Because the difference of connection pipe fitting when pipeline uses, may have influence on and install and dismantle problems such as sealing whether convenient, pipeline.
Summary of the invention
The present invention discloses a kind of non-screw thread quick-connecting pipe fitting, has overcome the processed complex that existing pipeline thread Placement exists, shortcomings such as dismounting trouble.
Technical solution of the present invention is as follows:
Constitute connection pipe fitting by tube head, adapter, pipe clamp and seal ring, wherein, the described tube head connecting end outside is provided with an annular seal groove and ring-type taper positioning table, and positioning table is provided with limited ring, and seal ring is embedded in the sealed groove; The connecting end of described adapter is enclosed within on the connecting end of tube head and is connected, and takes over the connecting end outside and is provided with the ring-type positioning groove; Described pipe clamp is connected and composed by location snap ring and two connecting bands of release snap ring by symmetry, the location card ring set is contained on the positioning table of tube head, constituting secure fit by limited ring connects, it is oval discharging snap ring, its minor axis inboard is provided with buckle and cooperates the formation auxiliary connection with the outside ring-type positioning groove of adapter, its longitudinal end discharges the position for pushing, and the minor axis end outwards opens with the ring-type positioning groove of taking over and separates when inwardly pushing, and adapter can separate dismounting with tube head, pipe clamp.
Be evenly distributed with some location protruding pin on the axle facade of the positioning table upper limit ring of described tube head, the inboard corresponding protruding pin of the location snap ring of pipe clamp is distributed with positioning groove and constitutes the axially locating auxiliary connection.
The location snap ring of described pipe clamp is the open type structure.
Working procedure of the present invention is as follows: pipe clamp is enclosed within on the tube head, and location snap ring and positioning table chucking are fixing, and make the two axially locating by the location protruding pin on the limited ring; Adapter is inserted in the connecting end of tube head, is tightly connected by seal ring and tube head, and the outside ring-type positioning groove of adapter and the release snap ring fixing and locking of pipe clamp are finished quick connection.When inwardly pushing the longitudinal end of pipe clamp, the minor axis end of pipe clamp outwards opens with the ring-type positioning groove of taking over and separates, and adapter, tube head, pipe clamp separate dismounting.
Good effect of the present invention is: adopt pipe clamp as bindiny mechanism, tube head can be connected fast with adapter and fix, have characteristics such as dismounting is quick, good airproof performance, oil resistant, intensity height, can be widely used in automobile and civil pipeline and connect in facility and the device.
