Description

Technical Field

[0001] The present application relates to the technical field of disassembly and assembly tools, and in particular to a disassembly and assembly tool for circular water pipes. Background Art

[0002] Currently, commonly used tools for disassembling and assembling round water pipes, such as pipe wrenches, duckbill pliers, and locking pliers, must be stuck on the outer surface of the water pipe. They are often not stuck tightly, slip, and damage the outer water pipe threads and surfaces. This is especially true for pipes with relatively smooth surfaces, where it is difficult for general tools to apply force.

[0003] Therefore, in order to meet the actual needs, a disassembly and assembly tool for a circular water pipe is provided. Summary of the invention

[0004] In view of the defects existing in the prior art, the purpose of this application is to provide a disassembly and assembly tool for circular water pipes, which utilizes the circular ring structure of the tubular object, combines actual usage needs, and cooperates with a multi-point physical structure to facilitate the disassembly and assembly of circular water pipes and improve work efficiency.

[0005] In order to achieve the above objectives, the technical solution adopted by this application is:

[0006] The present application provides a disassembly and assembly tool for a circular water pipe, the disassembly and assembly tool comprising:

[0007] handle;

[0008] A disc-shaped structure is arranged at one end of the handle, and a pair of in-tube clamping fulcrums are arranged on the disc-shaped structure;

[0009] An outer tube movable fulcrum is arranged on the disc-shaped structure, and the outer tube movable fulcrum is configured to be able to adjust the orientation within a preset linear movement range;

[0010] A pair of the inner-tube clamping fulcrums and the outer-tube movable fulcrum are arranged in a triangle;

[0011] The inner-tube clamping fulcrum and the outer-tube movable fulcrum are cylindrical structures;

[0012] The disc-shaped structure includes a fixed disc and a rotating disc rotatably arranged on the fixed disc;

[0013] A pair of said inner-tube clamping fulcrums are located on said rotating disk;

[0014] The outer movable fulcrum of the tube is arranged on the fixed plate.

[0015] It should be noted that the tool uses the inner surface, outer surface and wall of the pipeline to form a force angle difference, which generates torque when the handle is rotated, causing the pipeline to rotate clockwise or counterclockwise, thereby facilitating the rotation of the pipeline.

[0016] On the basis of the above technical solution, a rotation direction regulator is provided on the handle, and the rotation direction regulator is drivingly connected to the rotating disk.

[0017] Specifically, the handle is a force-applying handle that is fixed in position, and its size and shape can be changed arbitrarily according to usage requirements. The handle and the fixed plate are a whole, and cooperate with the rotation direction adjuster to adjust the rotation to the best force-applying position.

[0018] In order to prevent damage to the inner wall of the pipe and to ensure a tighter fit, the shape of the location where the inner clamping fulcrum fits the pipe wall can be changed, and the resistance design is increased so that the inner clamping fulcrum fits the pipe wall more closely and the force is better applied.

[0019] On the basis of the above technical solution, the preset linear movement range corresponding to the movable fulcrum outside the tube is on the fixed plate.

[0020] On the basis of the above technical solution, the moving direction of the movable fulcrum outside the tube is parallel to the length direction of the handle.

[0021] On the basis of the above technical solution, the outer movable fulcrum of the tube is arranged on the fixed plate through a movable fulcrum movement control mechanism;

[0022] The movable fulcrum movement control mechanism comprises:

[0023] A pair of oppositely arranged latching slots, wherein the latching slots include a plurality of latching cavities arranged at intervals, and the latching cavities of the two latching slots are opposite to each other;

[0024] A detachable locking pin is disposed in a pair of the locking grooves, the side wall of the locking pin is provided with a locking rib matching the locking cavity, a connecting cylinder is provided inside the locking pin, the inside of the connecting cylinder is connected to the outer movable fulcrum of the tube through a spring, and the inner diameter of the connecting cylinder is greater than the diameter of the outer movable fulcrum of the tube;

[0025] A movable slide groove, on which the connecting end of the movable fulcrum outside the tube and the spring can slide;

[0026] When the locking pin is pulled out from the locking groove and the locking rib is separated from the locking cavity, the connecting cylinder is separated from the outer movable fulcrum of the tube, and the spring is in a stretched state;

[0027] When the locking pin penetrates into the locking groove, the locking rib and the locking cavity cooperate with the locking pin, the connecting cylinder is sleeved on the movable fulcrum outside the tube, and the spring is in a free state.

[0028] On the basis of the above technical solution, the free end of the clamping fulcrum in the tube is provided with a fulcrum slope;

[0029] The support slope surface is a stepped slope surface or a curved slope surface.

[0030] On the basis of the above technical solution, a fulcrum protrusion is provided on the side wall of the free end of the movable fulcrum outside the tube.

[0031] It should be noted that in order to allow the outer movable fulcrum to be better set on the fixed plate, a protrusion area can be set at the upper end of the fixed plate, and the outer movable fulcrum can be set on the protrusion area, thereby providing corresponding space for the preset linear movement range corresponding to the outer movable fulcrum.

[0032] On the basis of the above technical solution, the disassembly and assembly tool further comprises:

[0033] The two ends of the in-tube clamping fulcrum connecting rod are sleeved or fixed on the two in-tube clamping fulcrums.

[0034] It should be noted that the outer movable fulcrum is arranged on the fixed plate, and the corresponding preset linear moving range is on the fixed plate.

[0035] Since the outer movable fulcrum is arranged on the fixed plate, when force is applied, it has certain technical advantages in stability through the outer movable fulcrum and the fixed plate.

[0036] In addition, the outer movable fulcrum of the pipe is arranged on the fixed plate, and the corresponding preset linear moving range is on the fixed plate, which can adapt to the water pipe structure with thicker pipe wall.

[0037] Compared with the prior art, the advantages of this application are:

[0038] The present application utilizes the circular ring structure of the tubular object, combines it with actual usage needs, and cooperates with a multi-point physical structure to facilitate the disassembly and assembly of the circular water pipe and improve work efficiency.

[0077] Furthermore, a rotation direction regulator 7 is provided on the handle 1 , and the rotation direction regulator 7 is transmission-connected to the rotating disk 6 .

[0078] Specifically, the handle 1 is a force-applying handle that is fixed in position, and its size and shape can be changed arbitrarily according to usage requirements. The handle 1 and the fixed plate 5 are integrated, and cooperate with the rotation direction adjuster 7 to adjust the rotation to the optimal force-applying position.

[0079] As shown in the attached figure of the specification Figure 1 and Figure 2 As shown, the said in-tube clamping fulcrum 3, the in-tube clamping fulcrums A and B can be integrated or independent;
