Description

Internal thread pipe subassembly

Technical Field

The utility model relates to a pipe installation technical field especially relates to an internal thread pipe subassembly.

Background

The screw thread is the important component part of pipe installation, and traditional pipe preparation mode is welded nut or screw thread finished piece in the one end of pipe and is polished smoothly to cause the production processes numerous, lead to manufacturing cost to remain high.

Disclosure of Invention

The utility model provides a can effectively reduce production processes, reduction in production cost's internal thread pipe subassembly.

The utility model adopts the technical proposal that: an internally threaded round tubular assembly comprising: a circular tube, a pipe sleeve and a connecting piece; the connecting piece comprises a bolt and a nut in threaded connection with the bolt; the circular tube is provided with a connecting end, an installation groove is formed in the connecting end, and the nut is installed in the installation groove;

the pipe sleeve is sleeved outside the connecting end, and the lower end of the pipe sleeve is provided with a contraction opening; the bolt comprises a nut and a bolt column integrally formed with the nut, and the outer diameter of the nut is larger than the inner diameter of the contraction opening.

Furthermore, a blocking piece buckled inside is arranged at the port of the connecting end.

Compared with the prior art, the internal thread round pipe assembly of the utility model has the advantages that the nut is arranged in the mounting groove by arranging the mounting groove at the connecting end of the round pipe; simultaneously, the lower end of the pipe sleeve is provided with the contraction port, and the outer diameter of the nut is larger than the inner diameter of the contraction port, so that the pipe sleeve is effectively and firmly installed on the circular pipe, production procedures can be effectively reduced, and production cost is reduced.

Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings. It is to be understood that the description of the embodiments herein is for purposes of illustration and explanation only and is not intended to limit the invention.

As shown in fig. 1 and 3, the internal thread circular tube assembly of the present invention includes a circular tube 1, a tube sleeve 2, and a connecting member; wherein, the pipe sleeve 2 is sleeved outside the circular pipe 1, and the connecting piece is connected with the circular pipe 1 and the pipe sleeve 2.

As shown in fig. 2 to 4, specifically, the connecting member includes a bolt 4 and a nut 3 threadedly coupled to the bolt 4. Pipe 1 is equipped with link 101, is equipped with mounting groove 102 in the link 101, and nut 3 installs in mounting groove 102 to reduce the welding and polish or attack production processes such as tooth, effective reduction in production cost. Further, the port of the connecting end 101 is provided with an inward-buckled blocking piece 103 for blocking the nut 3 and preventing the nut 3 from falling out of the mounting groove 102.

The pipe sleeve 2 is sleeved outside the connecting end 101, and the inner diameter of the pipe sleeve 2 is larger than the outer diameter of the circular pipe 1, so that the pipe sleeve 2 is conveniently sleeved outside the connecting end 101. The lower end of the pipe sleeve 2 is provided with a contraction opening 201. The bolt 4 includes a nut 40 and a stud 41 integrally formed with the nut 40; wherein, the external diameter of nut 40 is greater than the internal diameter of shrink-on 201, inserts nut 3 from shrink-on 20 when bolt 4 to with nut 3 threaded connection fastening back, support through nut 40 and compress tightly on the outer fringe of shrink-on 20, thereby effectively install pipe box 2 firmly on pipe 1, avoid bolt 4 excessively to stretch into in the link 101 simultaneously.

The utility model discloses the assembly process of internal thread pipe subassembly as follows:

firstly, sleeving the pipe sleeve 2 on the connecting end 101, so that the contraction port 201 is aligned with the nut 3; then, the bolt 4 is inserted into the nut 3 from the contraction port 201, and the socket 2 is attached to the circular tube 1 by tightening the bolt 4.

To sum up, the inner thread round tube component of the utility model arranges the mounting groove 102 on the connecting end 101 of the round tube 1, and the nut 3 is mounted in the mounting groove 102; simultaneously through setting up shrink-fit 201 at the lower extreme of pipe box 2, and the external diameter of nut 40 is greater than the internal diameter of shrink-fit 201 to effectively install pipe box 2 firmly on pipe 1, can effectively reduce production processes moreover, reduction in production cost.

As long as the idea created by the present invention is not violated, various different embodiments of the present invention can be arbitrarily combined, and all the embodiments should be regarded as the content disclosed by the present invention; the utility model discloses an in the technical conception scope, carry out multiple simple variant and different embodiments to technical scheme and go on not violating the utility model discloses the arbitrary combination of the thought of creation all should be within the protection scope.
