Detailed Description

The present invention is further described in the following description with reference to specific embodiments and the accompanying drawings, wherein the details are set forth in order to provide a thorough understanding of the present invention, but it is apparent that the present invention can be embodied in many other forms different from those described herein, and it will be readily appreciated by those skilled in the art that the present invention can be implemented in many different forms without departing from the spirit and scope of the utility model.

It is noted that these and other figures which follow are merely exemplary and not drawn to scale and should not be considered as limiting the scope of the utility model as it is actually claimed.

In the conventional piping structure shown in fig. 1, the hose 21 has a hose connector 25, the hard tube 22 has a hard tube connector 24, and the hose/hard tube connection section 23 is connected to the hard tube 22 by means of a nut 26 to connect the hose 21 and the hard tube 22.

When disassembly is required, the hard tube 22 will follow the outer nut 26 due to friction, creating stress at the weld of the hard tube fitting 24. In addition, the hose 21 will follow the rotation of the hard tube 22 due to friction, and the other end of the hose 21 is fixed, so the hose 21 is easy to be distorted or even broken, thereby affecting the normal transportation of the medium in the hose.

The hard coupling 24 of the hard tube 22 is typically removed by securing the male portion with an open ended wrench and then tightening or loosening the female portion with an open ended wrench. The disassembly and assembly of the pipe joint is more complicated when the hose is connected with the hard pipe, and the current disassembly and assembly operation is as shown in fig. 2, firstly two open wrenches 30 are needed to respectively fix the hose joint 25 on the hose 21 and the hard pipe joint 24 at the joint of the hard pipe 22, and then the third open wrench 30 is used to screw down or unscrew the outer nut 26, so that the hose 21 is ensured not to be twisted in the operation process to bring additional stress, and further the disassembly and assembly of the pipeline are completed.

Above-mentioned operation process is comparatively complicated, needs two operating personnel to operate simultaneously usually, causes the human cost extravagant to because operating space is little, two operating personnel are difficult for the application of force, and pipeline joint department screws up the moment great, and dismouting operation cost time is longer.

In addition, because two spanners at the joint of the fixed hose and the hard tube are held by two hands of one operator, because the force application of the two hands has difference, the conduit at the two ends of the pipe joint cannot be fixed at the same time, and finally the pipe body is twisted to generate stress, and certain error must exist in the operation process of different operators during the dismounting at each time, so that the operation is lack of consistency.

In order to solve the problems, the multi-angle pipe joint installation tool can be used for simultaneously controlling two pipe joints by one worker, can conveniently and quickly fix the pipe joint and improve the reliability of operation.

The perpendicular arrangement between the first wrench 31 and the second wrench 32 can be realized by the right-angle bending mechanism 50, so that the second wrench 32 fixed at the end of the mounting rod 42 and the first wrench 31 fixed at the end of the first mounting rod 41 can be simultaneously matched with joints of pipelines with different angles, such as the right-angle pipeline shown in fig. 1. And the two wrenches do not deflect relatively, so that the two pipe joints do not drive the pipelines to twist relatively, and additional stress cannot be generated on the welding seams and the pipe bodies of the hoses.

Preferably, the first transition section 43 is telescopically connected to the fixed mounting rod 42. In the embodiment shown in fig. 3, the fixed mounting bar 42 comprises a vertical bar 421 and a horizontal bar 422, the vertical bar 421 is used for mounting the second wrench 32, and the horizontal bar 422 comprises an inner cavity and a socket.

When different specification and dimension pipelines are screwed down, the first switching section 43 can be selected to extend out a proper length according to the actual size of the pipeline, the pipeline size is matched quickly, the time for selecting and matching the wrench head is shortened, and the adaptability of the tool to various pipeline sizes is improved.

In another embodiment, the fixed mounting rod 42 comprises a vertical rod 421 and a horizontal rod 422, the vertical rod 421 is used for mounting the second wrench 32, the horizontal rod 422 comprises an internal thread, the first adapter section 43 comprises an external thread, the first adapter section 43 and the horizontal rod 422 are connected by screw threads and are fixed by a nut, and the effect of telescopically connecting the first adapter section 43 and the fixed mounting rod 42 can also be achieved.

In another embodiment, the pipe joint installation tool no longer connects the fixed installation rod 42 and the first installation rod 41 through the right-angle bending mechanism 50, but connects through an adapter portion of another shape. The switching portion includes third switching section and fourth switching section, and the third switching section is used for being connected with first installation pole 41, and the fourth switching section is used for being connected with fixed mounting pole 42, and third switching section and fourth switching section are articulated.
