[0023] The present invention will be further described below with reference to the accompanying drawings.

[0024] like Figure 1 As shown, the pipe shackle device of the present invention may include a first pliers body 1 and a second pliers body 2, both of which are arc-shaped structures. The head ends of the first pliers body 1 and the second pliers body 2 are rotatably connected, the inner arc surfaces of the first pliers body 1 and the second pliers body 2 correspond to each other and the inner arc surfaces are both detachably installed with pliers teeth 3, and the tail ends of the first pliers body 1 and the second pliers body 2 are provided with locking components, which cooperate with the first pliers body 1 and the second pliers body 2 to clamp the pipe.

[0025] Specifically, both the first and second jaws 1 and 2 have arcuate structures for conveniently clamping pipes. They are rotatably connected at their head ends and connected at their tail ends via a locking assembly, facilitating installation and removal of the device. The first and second jaws 1 and 2 cooperate to clamp the pipe between their inner curved surfaces. The jaws 3 on the inner curved surfaces abut against the outer wall of the pipe to achieve clamping, and torque is transmitted during rotation to tighten or loosen the pipe.

[0026] The pipe shackle device can clamp the pipe by cooperating with the first clamp body 1 and the second clamp body 2 through the locking component. It has a simple structure, is lightweight and easy to install. Under the action of external force, the first clamp body 1 and the second clamp body 2 are rotated to shackle the pipe through the clamp teeth 3 on the inner arc surface. After locking, shackle is safer and more reliable, which can improve the safety factor of operation. The rotation of the clamp teeth 3 saves effort and prevents slipping, which can reduce labor intensity.

[0027] In one example, the central angles corresponding to the arcs of the first pliers body 1 and the second pliers body 2 are both 120°-180°.

[0028] Specifically, the first pliers body 1 and the second pliers body 2 cooperate with the locking assembly to form a circular ring that can wrap around the pipe. When the central angles corresponding to the arcs of the first pliers body 1 and the second pliers body 2 are the same, the central angles corresponding to the arcs of the two pliers bodies can be 180°, 160°, or 140°, etc.; when the central angles corresponding to the arcs of the first pliers body 1 and the second pliers body 2 are different, the central angle corresponding to the arc of the first pliers body 1 can be 180°, 170°, 150°, or 130°, etc., and the central angle corresponding to the arc of the second pliers body 2 can be 180°, 170°, 150°, or 130°, etc. It should be noted that when the arc structures of the first pliers body 1 and the second pliers body 2 do not form a complete circular ring, the missing part can be supplemented by the setting of the locking assembly.

[0029] In one example, the jaws 3 are fixedly arranged on the inner side surface of the arc-shaped plate 4 , and the arc-shaped plate 4 is mounted on the inner arc surface of the first jaw body 1 and / or the second jaw body 2 through bolts 5 .

[0030] Specifically, the number of jaws 3 is multiple and evenly distributed on the inner side of the curved plate 4. The jaws 3 can be fixed to the curved plate 4 by welding or integral molding. The curved plate 4 is then connected to the inner curved surface of the first jaw body 1 and / or the second jaw body 2 by bolts 5 to achieve a detachable connection. This facilitates the replacement of different jaws 3 models that match the jaw body according to the size of the pipe.

[0031] Furthermore, jaws 3 are installed on the inner arc surfaces of the first jaw body 1 and the second jaw body 2, and the jaws 3 are fixed to the arc plate 4 by welding, and the arc plate 4 is then fixed to the inner arc surfaces of the first jaw body 1 and the second jaw body 2 by hexagonal bolts 5.

[0032] In one example, the head ends of the first caliper body 1 and the second caliper body 2 are hinged via a pin 6 to achieve a rotational connection.

[0033] In one example, the locking assembly includes a handle 7 connected to the rear end of the first caliper body 1 and a locking tongue 8 connected to the rear end of the second caliper body 2. The head end of the handle 7 can be engaged with the locking tongue 8 for locking. When the head end of the handle 7 is engaged with the locking tongue 8 for locking, the locking assembly can be further tightened by rotating the rear end of the handle 7. When locked to a certain degree, the handle 7 can pry the caliper body, and the force transmitted through the caliper body to the jaws 3 applies a twisting force to the pipe to tighten or loosen the pipe.

[0034] In one example, the locking tongue 8 is a protrusion fixedly provided on the outer arc surface at the tail end of the second caliper body 2, and the end of the protrusion is bent along the arc path corresponding to the outer arc surface in the direction away from the tail end of the first caliper body 1, and a slot is formed between the bent end of the protrusion and the outer arc surface. The head end of the handle 7 has a clip, which can be inserted into the slot for locking.

[0035] Furthermore, the lock tongue 8 has a concave structure, and the clamp has a T-shaped structure. The wider head of the clamp can be inserted into the slot and abut against the outer arc surface of the second caliper body 2 and the lock tongue 8, and the narrower body of the clamp can be inserted into the recess of the lock tongue 8 to facilitate the rotation of the handle 7.

[0036] In one example, the handle 7 is hinged to the rear end of the first pliers 1 near its head end. The handle 7 can be rotated under the action of an external force to allow the clamp to approach and engage the clamping slot. After the clamping slot is engaged, the handle 7 can be further rotated to pull the rear ends of the first pliers 1 and the second pliers 2 toward each other and close them together, thereby clamping the pipe and applying a torsional force to tighten or loosen the pipe. In this way, the tighter the locking assembly locks the first pliers 1 and the second pliers 2, the more conducive it is for the jaws 3 to apply a torsional force to the pipe, preventing the jaws 3 from slipping and improving safety.

[0037] In one example, the locking assembly further includes a fixing block 9 and a hinge mechanism. The fixing block 9 is fixedly disposed on the outer arc surface of the tail end of the first pliers body 1 , and the fixing block 9 is connected to the handle 7 via the hinge mechanism.

[0038] In one example, the hinge mechanism includes a connecting rod 10, one end of the connecting rod 10 is hinged to the fixing block 9, and the other end of the connecting rod 10 is hinged to a position near the head end of the handle 7. Both hinges can be connected by a pin 6.

[0039] In one example, there are two connecting rods 10 , which are symmetrically distributed on both sides of the handle 7 and the fixing block 9 .

[0040] In order to better understand the above embodiment, the working process of the pipe shackle device will be further described below with reference to the accompanying drawings.

[0041] When in use, select the matching jaws 3 according to the size of the pipe, and the jaws 3 are installed on the inner side of the jaw body through the arc plate 4; then open the locking assembly, install the buckle device on the pipe, then close the locking assembly and observe the engagement of the jaws 3 with the pipe; if the engagement is good, apply force to rotate the handle 7 to pull the tail end of the first jaw body 1 and the tail end of the second jaw body 2 toward each other and close them, so as to clamp the pipe and apply a torsional force to tighten or loosen the pipe.

[0042] While the present invention has been described with reference to preferred embodiments, various modifications may be made and equivalent components may be substituted without departing from the scope of the present invention. In particular, the various technical features described in the various embodiments may be combined in any manner, provided no structural conflicts exist. The present invention is not limited to the specific embodiments disclosed herein, but encompasses all technical solutions within the scope of the claims.
