In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0026] Combined with the attached Figure 1 and the attached Figure 2 and the attached drawings, the present application relates to a disassembly tool for a connecting pipe. The disassembly tool includes a pressure seat 100, a support seat 200 and a force-applying member. The pressure seat 100 is fixedly arranged at the journal of the connecting pipe. The connecting pipe penetrates through the pressure seat 100. The force-applying member is arranged on the support seat 200. The support seat 200 is arranged between the base of the connecting pipe and the pressure seat 100, and one end of the support seat 200 facing the base of the connecting pipe is used to abut against the base of the connecting pipe.

[0027] It should be noted that the pressure seat 100 is located between the shoulder of the journal on the connecting pipe and the force-applying member, and the shoulder of the journal on the connecting pipe abuts against the side surface of the pressure seat 100. The force-applying member can apply a thrust force to the pressure seat 100 and push the pressure seat 100 to move away from the base of the connecting pipe, and the pressure seat 100 applies a thrust force to the connecting pipe, so that the connecting pipe is separated from the base of the connecting pipe.

[0028] Specifically, the force-applying member can apply a thrust force to the pressure seat 100 in a rotating manner. The user operates the force-applying member to make the force-applying member rotate, so that the force-applying member can contact the pressure seat 100 and generate a thrust force on the pressure seat 100.

[0029] As an implementation, two force-applying members are arranged on the support seat 200, and the two force-applying members are symmetrically arranged on both sides of the support seat 200. Specifically, the two force-applying members are respectively located on both sides of the connecting pipe to be disassembled, and the two force-applying members respectively apply thrust forces to both ends of the side surface of the pressure seat 100, so that the pressure seat 100 is evenly stressed, and further ensure that the pressure seat 100 can move smoothly along the length direction of the connecting pipe.

[0030] Furthermore, the support seat 200 has two side walls arranged at intervals, and the side walls extend along the length direction parallel to the connecting pipe. A groove 210 for accommodating the connecting pipe is formed at intervals between the two side walls of the support seat 200. The groove 210 extends along the length direction parallel to the connecting pipe, and the two force-applying members are respectively arranged on the two side walls of the support seat 200.

[0031] It can be understood that the connecting pipe to be disassembled is partially located in the groove body 210, and the support seat 200 uses the groove body 210 to play a role in avoiding and accommodating the connecting pipe. On the other hand, by arranging the force - applying component on the side wall of the support seat 200, it can be ensured that the thrust action point of the force - applying component on the side of the pressure seat 100 is far from the bottom or top of the pressure seat 100, ensuring the balanced force on the pressure seat 100.

[0032] As an implementation manner, the disassembly tooling includes a tightening member 300. At least one tightening member 300 is arranged at one end of the support seat 200 facing the connecting pipe base. The tightening member 300 can move on the support seat 200 and press against the connecting pipe base.

[0033] Furthermore, the tightening member 300 is threadedly connected to the support seat 200, and the tightening member 300 realizes movement in the support seat 200 in a screw - drive manner. Specifically, at one end of two spaced - apart side walls of the support seat 200 facing the connecting pipe base, a tightening member 300 is arranged, and a threaded hole is provided at the end of the side wall. The tightening member 300 is provided with an external thread.

[0034] In some examples, the tightening member 300 is set as a screw or a stud or a bolt.

[0035] As an implementation manner, the pressure seat 100 includes two top seats 110. The two top seats 110 are respectively arranged on both sides of the connecting pipe. The two top seats 110 are fixedly connected between them to clamp the journal of the connecting pipe, and the two top seats 110 clamp the journal of the connecting pipe in a hugging manner. Specifically, mounting holes are provided at both ends of the top seat 110, and bolts or bolts pass through the mounting holes to fixedly connect the two top seats 110.

[0036] It can be understood that the force - applying component acts on one of the top seats 110, and the force - applying component presses against the top seat 110 to push the entire pressure seat 100.

[0037] Furthermore, at least one top seat 110 is provided with a groove for arranging the journal. In some examples, one of the top seats 110 is provided with a groove. After the two top seats 110 are fixedly connected, the groove is buckled at the journal. In other examples, both of the two top seats 110 are provided with grooves. After the two top seats 110 are fixedly connected, the grooves of the two top seats 110 hug each other to form a circular hole and are buckled at the journal.

[0038] As an implementation manner, the force - applying component includes a cam or an eccentric wheel 400. The cam or the eccentric wheel 400 is connected to the support seat 200 through a rotating shaft. One end of the rotating shaft is rotatably arranged on the support seat 200, and the user rotates the rotating shaft to make the cam or the eccentric wheel 400 push the pressure seat 100. Specifically, when the user rotates the other end of the rotating shaft with a tool, the rotating shaft drives the cam or the eccentric wheel 400 to rotate.

[0039] It can be understood that when one end of the outer contour of the cam or eccentric wheel 400 that is far from the rotation center contacts the pressure seat 100, as the cam or eccentric wheel 400 rotates, the cam or eccentric wheel 400 gradually pushes the pressure seat 100.

[0040] Furthermore, cams or eccentric wheels 400 are provided on the outer sides of two side walls of the support seat 200 that are arranged at intervals.

[0041] As another alternative embodiment, the force - applying component includes a first ejector rod, and one end of the first ejector rod abuts against the pressure seat 100. Further, the first ejector rod is moved on the support seat 200 in a screw - drive manner so that the first ejector rod pushes the pressure seat 100.

[0042] It can be understood that the support seat 200 is provided with a threaded hole, and the first ejector rod is provided with an external thread. When the user rotates the first ejector rod, the first ejector rod moves on the support seat 200, and the end of the first ejector rod abuts against the pressure seat 100, thereby pushing the pressure seat 100.

[0043] In some examples, the first ejector rod is set as a screw or a bolt or a stud.

[0044] It should be noted that there are also the following alternative embodiments for the disassembly tooling.

[0045] Combined with the attached Figure 3 and the attached Figure 4 The disassembly tooling includes a pressure seat 100 and a second ejector rod 500. The pressure seat 100 is used to be fixedly arranged at the journal of the connecting pipe. The connecting pipe penetrates through the pressure seat 100. The second ejector rod 500 is arranged on the pressure seat 100. The second ejector rod 500 penetrates through the pressure seat 100, and one end of the second ejector rod 500 abuts against the connecting - pipe base. With the connecting - pipe base as a support, the second ejector rod 500 can push the pressure seat 100 in a direction away from the connecting - pipe base, and the pressure seat 100 exerts a thrust on the connecting pipe, so that the connecting pipe is separated from the connecting - pipe base.

[0046] Specifically, the second ejector rod 500 pushes the pressure seat 100 in a screw - drive manner. The pressure seat 100 is provided with a threaded hole, and the second ejector rod 500 is provided with an external thread. When the user rotates the second ejector rod 500, the thread of the second ejector rod 500 exerts a thrust on the pressure seat 100 to make the pressure seat 100 move.

[0047] Furthermore, two second ejector rods 500 are provided. The two second ejector rods 500 are respectively located on both sides of the connecting pipe to be disassembled. The two second ejector rods 500 are symmetrically arranged on the pressure seat 100 so that the pressure seat 100 is evenly stressed, thereby ensuring that the pressure seat 100 can move smoothly.

[0048] In some examples, the second ejector rod 500 is set as a screw or a bolt or a stud.

[0049] As an implementation manner, the disassembly tooling includes a cushion block 600. The second ejector rod 500 presses against the connecting pipe base through the cushion block 600 to prevent the second ejector rod 500 from damaging the connecting pipe base.

[0050] It should be noted that the structure of the pressure seat 100 has been described above and will not be elaborated here.

[0051] The embodiments of the present application have been described in detail with reference to the accompanying drawings. However, the present application is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the purpose of the present application.
