Description

Technical Field

[0001] The utility model relates to the technical field of open-end wrenches, and more specifically to an adjustable vertical pipe live-joint open-end wrench. Background Art

[0002] A union is a type of pipe fitting with a three-dimensional polygonal shape and three-dimensional threads engraved on the inner layer. The connection form is a fixed joint and a union joint used in conjunction with each other. The two ends are connected to the corresponding pipe threads and sealed in the middle with a PVC pad or rubber pad.

[0003] During daily rescue and maintenance work on indoor and outdoor risers, gas companies, water companies and other pipeline companies often need to dismantle and install live joints when replacing live joints or rubber pads inside live joints. Various wrench tools are often required for dismantling and installing live joints. Various tools such as pipe pliers and adjustable wrenches are prone to falling due to the slope of the contact surface with the live joints, resulting in safety hazards during the installation and maintenance process. In addition, when using pipe pliers, adjustable wrenches and open-end wrenches, when the distance between the wall and the pipe is close, the overall rotation range of the wrench will be affected, resulting in the efficiency of dismantling and installing the live joints being affected. Therefore, they need to be improved. Utility Model Content

[0033] The switch mechanism is arranged inside the fixing sleeve 7 .

[0034] Due to the design of the wrench body 1, the operator can engage the wrench body 1 with the riser joint to install and disassemble the riser joint. During use, when the distance between the wall and the pipeline is close, the operator can move the two clamping plates 6 towards each other to enter the interior of the fixing box 3, thereby releasing the fixing effect between the fixing box 3 and the wrench body 1, so that the fixing box 3 can be taken out from the interior of the slot 2 and then reinstalled into the interior of other slots 2.

[0035] The switch mechanism includes:

[0036] A rotating rod 8, the outer surface of the rotating rod 8 is movably sleeved with the inner surface of the fixed sleeve 7, the bottom end of the rotating rod 8 passes through the fixed box 3 and extends to the bottom of the fixed box 3 and is movably sleeved with the inner wall of the fixed box 3, and a rotating plate 9 is fixedly sleeved at the bottom of the outer surface of the rotating rod 8;

[0037] A connecting soft rope 10 is provided, one end of which is fixedly connected to the inner surface of the clamping plate 6 , and the other end of which passes through the mounting plate 4 and is fixedly connected to the outer surface of the rotating rod 8 .

[0038] The operator can rotate the rotating plate 9 so that the rotating plate 9 drives the rotating rod 8 to rotate, and then the connecting soft rope 10 can be rolled up on the outer surface of the rotating rod 8, thereby driving the two clamping plates 6 to move towards each other.

[0039] A first handle 11 is fixedly mounted on the bottom of the fixing box 3 , and an inner wall of the first handle 11 is movably sleeved with an outer surface of the rotating rod 8 .

[0040] The operator can hold the rotating rod 8 to drive the wrench body 1 to install and disassemble the vertical pipe joint.

[0041] A slide groove 12 is provided on the front of the first handle 11 , and a slider 13 is movably installed on the top of the inner surface of the slide groove 12 .

[0042] By providing the slide groove 12 , the slide groove 12 can limit the slider 13 , so that the slider 13 can move along the inner surface of the slide groove 12 .

[0043] Among them, the outer surface of the slider 13 is fixedly connected to a movable ring 14, the inner surface of the movable ring 14 is movably connected to the outer surface of the first handle 11, the outer surface of the movable ring 14 is fixedly connected to the second handle 15, and the top threaded sleeve of the back of the second handle 15 is connected to a bolt 20.

[0048] By providing the second spring 19 , the second spring 19 can push the movable ring 14 and the second handle 15 to return to their original positions under the action of elastic recovery after being compressed.

[0049] The working principle and use process of this utility model:

[0050] When the operator needs to dismantle and install the vertical pipe joint against the wall, he can rotate the rotating plate 9, so that the rotating plate 9 drives the rotating rod 8 to rotate, and then the rotating rod 8 can reel in the connecting soft rope 10, so that the two clamping plates 6 move towards each other, thereby releasing the fixing effect between the wrench body 1 and the fixing box 3, so that the operator can insert the fixing box 3 as a whole into the inside of the clamping slot 2 at other positions, so that the operator can choose the best angle when dismantling and installing the joint, and rotate the wrench body 1 to the maximum extent, thereby improving the efficiency of installing and dismantling the joint.

[0051] When the operator needs to disassemble the joint that is difficult to disassemble due to rust, the operator can pull the second handle 15 downward so that the movable ring 14 drives the slider 13 to move along the inner surface of the slide groove 12, thereby limiting the second handle 15, and at the same time, the limit block 18 can limit the second handle 15 through the limit groove 16, so that the second handle 15 can only move up and down but cannot rotate. When the second handle 15 moves downward, the operator can rotate the bolt 20 so that the bolt 20 contacts the outer surface of the first handle 11, thereby fixing the second handle 15, thereby extending the overall length of the first handle 11 and the second handle 15, which makes it easier for the operator to disassemble the rusted joint.
