Description

Technical Field

[0001] This utility model belongs to the field of pipe wrench technology, specifically relating to a pipe wrench with quick adjustable positioning. Background Technology

[0002] Pipe wrenches are tools used to rotate or fix round pipe fittings, cylindrical workpieces, etc. They are widely used in pipeline installation, maintenance, and various occasions involving the handling of round objects.

[0003] However, existing pipe wrenches typically require a long time to rotate the screw sleeve to move them to the desired position due to the positioning of the movable clamp. This is particularly cumbersome, time-consuming, and labor-intensive in scenarios where the positioning needs to be adjusted frequently. For example, when it is necessary to quickly change pipe fittings of different diameters, operators need to spend a lot of time and effort to adjust the size of the jaws, which not only reduces work efficiency but may also increase the risk of misoperation.

[0004] Therefore, for the existing pipe wrenches mentioned above, since the positioning of their movable clamps usually requires a long time to drive the screw sleeve to move to the required position, resulting in cumbersome, time-consuming and laborious operation in use scenarios where the positioning needs to be adjusted frequently, a pipe wrench with quick positioning adjustment can be designed. Utility Model Content

[0005] To overcome the problem that existing pipe wrenches, whose movable clamps usually require a long time to rotate the screw sleeve to drive them to the required position, resulting in cumbersome, time-consuming and laborious operation in use scenarios where frequent positioning adjustments are required.

[0006] The technical solution of this utility model is as follows: a pipe wrench with quick-adjustable positioning, including a wrench bar, a clamp sleeve assembly, a movable clamp assembly, and a threaded sleeve; the upper end of the wrench bar is provided with the clamp sleeve assembly; the movable clamp assembly is movably arranged inside the clamp sleeve assembly; the lower part of the clamp sleeve assembly is provided with a threaded sleeve; the clamp sleeve assembly includes a movable clamp sleeve, a lower clamping jaw, a positioning hole, a positioning bead, a washer, a spring, and a locking screw; the movable clamp assembly includes an upper clamping jaw, a threaded rod, a positioning groove, and a sliding groove.

[0007] Preferably, the positioning bead is pushed into the sliding groove by a spring, so that when the threaded rod slides along the inner hole of the movable clamp sleeve for adjustment, it is held in place by the inward pressure, thereby achieving the function of rapid coupling and positioning. At this time, the threaded rod will not slide or deviate directly due to gravity. In conjunction with the threaded sleeve, it rotates and moves rapidly along the thread of the threaded rod, thereby completing the positioning and locking function of the upper clamp. This avoids the problem of slow adjustment of traditional pipe wrenches and solves the problem of cumbersome, time-consuming and laborious operation in the case of existing pipe wrenches, because the positioning of its movable clamp usually requires a long time to drive the screw sleeve to move to the required position, resulting in frequent positioning adjustments.

[0008] Preferably, a movable clamp sleeve is fixedly provided at the upper end of the clamp bar; a lower clamping opening is provided on the upper end face of the movable clamp sleeve; a threaded rod is provided on one side of the clamp bar, and the threaded rod passes through the movable clamp sleeve and moves up and down; an upper clamping opening is provided at the upper end of the threaded rod, and the upper clamping opening is integrally formed with the threaded rod.

[0009] Preferably, the front end face of the threaded rod is provided with a positioning groove; both sides of the positioning groove are provided with sliding grooves, and the sliding grooves are slidably connected with the inner wall groove of the movable hole inside the movable clamp sleeve.

[0010] Preferably, the front end face of the movable clamp sleeve is provided with a positioning hole, and the positioning hole is connected to the internal movable hole of the movable clamp sleeve.

[0011] Preferably, a positioning bead is provided inside the positioning hole; a washer is provided at the front end of the positioning bead; a spring is provided at the front end of the washer; a locking screw is provided at the front end of the spring, and the locking screw compresses the spring and is threadedly connected to the positioning hole.

[0012] Preferably, the threaded sleeve is connected to the threaded teeth on the outside of the threaded rod via a threaded drive.

[0013] Preferably, the spring's elastic compression pad pushes the positioning bead into the sliding groove.

[0014] The beneficial effects of this utility model are:

[0015] 1. Existing pipe wrenches often require prolonged rotation of the screw sleeve to move the movable clamp to the desired position, resulting in cumbersome, time-consuming, and labor-intensive operations in scenarios requiring frequent positioning adjustments. By using a spring to push the positioning ball into the sliding groove, the threaded rod is held in place by the inward pressure as it slides along the internal hole of the movable clamp sleeve, achieving rapid coupling and positioning. In this case, the threaded rod will not slide due to gravity. Combined with the rapid rotation of the screw sleeve along the thread of the rod, the upper clamp is positioned and locked, avoiding the slow adjustment problem of traditional pipe wrenches. This solves the problem of cumbersome, time-consuming, and labor-intensive operations in scenarios requiring frequent positioning adjustments, where the movable clamp of existing pipe wrenches typically requires prolonged rotation of the screw sleeve to move to the desired position.

[0016] 2. The sliding groove facilitates the stability of the threaded rod when it slides up and down along the movable hole inside the movable clamp sleeve, preventing the threaded rod from shaking during adjustment and improving the stability of the pipe clamp. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figure 1-4 This utility model provides an embodiment of a pipe wrench with quick-adjustable positioning, including a wrench bar 1, a clamp sleeve assembly 2, a movable clamp assembly 3, and a threaded sleeve 4; the clamp sleeve assembly 2 is provided at the upper end of the wrench bar 1; the movable clamp assembly 3 is movably arranged inside the clamp sleeve assembly 2; the threaded sleeve 4 is provided at the lower part of the clamp sleeve assembly 2; the clamp sleeve assembly 2 includes a movable clamp sleeve 201, a lower clamping jaw 202, a positioning hole 203, a positioning bead 204, a washer 205, a spring 206, and a locking screw 207; the movable clamp assembly 3 includes an upper clamping jaw 301, a threaded bar 302, a positioning groove 303, and a sliding groove 304.

[0024] Please see Figure 1-4In this embodiment, a movable clamp sleeve 201 is fixedly provided at the upper end of the clamp bar 1; a lower clamping opening 202 is provided on the upper end face of the movable clamp sleeve 201; a threaded rod 302 is provided on one side of the clamp bar 1, and the threaded rod 302 passes through the movable clamp sleeve 201 and is movably connected up and down; an upper clamping opening 301 is provided at the upper end of the threaded rod 302, and the upper clamping opening 301 and the threaded rod 302 are integrally formed; a positioning groove 303 is provided on the front end face of the threaded rod 302; sliding grooves 304 are provided on both sides of the positioning groove 303, and the sliding grooves 304 are slidably connected to the inner wall groove of the movable hole inside the movable clamp sleeve 201; the movable clamp sleeve 201... The front end face has a positioning hole 203 inside, and the positioning hole 203 is connected to the internal movable hole of the movable clamp sleeve 201; the positioning hole 203 has a positioning bead 204 inside; the front end of the positioning bead 204 has a washer 205; the front end of the washer 205 has a spring 206; the front end of the spring 206 has a locking screw 207, and the locking screw 207 compresses the spring 206 and is threadedly connected to the positioning hole 203; the threaded sleeve 4 is threadedly connected to the outer threaded teeth of the threaded rod 302; the elasticity of the spring 206 compresses the washer 205 and pushes the positioning bead 204 into the sliding groove 304.

[0025] During operation, the spring 206 pushes the positioning bead 204 into the sliding groove 304, causing the threaded rod 302 to be pressed against the inward pressure when sliding along the internal hole of the movable clamp sleeve 201, thus achieving the function of rapid coupling positioning. At this time, the threaded rod 302 will not slide or deviate directly due to gravity. In conjunction with the threaded sleeve 4, it rotates and moves rapidly along the thread of the threaded rod 302, thereby completing the positioning and locking function of the upper clamp 301, avoiding the problem of slow adjustment of traditional pipe wrenches. It solves the problem of existing pipe wrenches, where the positioning of the movable clamp usually requires a long time of rotation of the threaded sleeve to drive the displacement to the required position, resulting in cumbersome, time-consuming and laborious operation in use scenarios where frequent positioning adjustments are required.

[0026] Next, the sliding groove 304 facilitates the stability of the threaded rod 302 when it slides up and down along the movable hole inside the movable clamp sleeve 201, prevents the threaded rod 302 from shaking during sliding adjustment, and improves the stability of the pipe clamp.

[0027] Through the above steps, the positioning bead 204 is pushed into the sliding groove 304 by the spring 206, so that the threaded rod 302 is pressed inward by the internal pressure when it slides and adjusts along the internal hole of the movable clamp sleeve 201, thereby realizing the function of rapid coupling positioning. At this time, the threaded rod 302 will not slide or deviate directly due to gravity. With the help of the threaded sleeve 4, it rotates and moves quickly along the thread of the threaded rod 302, thereby completing the positioning and locking function of the upper clamp 301. This avoids the problem of slow adjustment of traditional pipe wrenches and avoids the problem of cumbersome, time-consuming and laborious operation in the application scenario of frequent positioning adjustment, because the positioning of the movable clamp of existing pipe wrenches usually requires a long time to drive the screw sleeve to move to the required position.

[0028] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
