Abstract
Description
Technical Field
[0001] This utility model relates to the field of tubing wrenches, specifically to a tubing wrench with a combined jaw plate. Background Technology
[0002] Pliers are a common hand tool, mainly used for clamping, cutting, or rotating objects. Pipe wrenches are a tool used for clamping and rotating pipes. Their principle is to convert clamping force into torque, using the taper of the jaws to increase torque to grip the tubular object. They are mainly used for operations such as threading and unthreading oil pipes. Before using pipe wrenches to perform threading and unthreading operations, you can select the appropriate jaw plate to assist the operation according to the type and outer diameter of the pipe string.
[0003] A Chinese patent publication number (CN219113931U) discloses a combined toothed wrench, including a tubing wrench body. The wrench body has a toothed wrench mechanism comprising: a plurality of toothed grooves sequentially formed on the left side of the toothed wrench; two clamps sequentially fixedly mounted on the right side of the toothed wrench; each clamp having a screw hole on its front; two screws threadedly connected to the inner wall of each screw hole; two anti-slip pads fixedly mounted at the rear ends of the two screws; and two limiting plates fixedly mounted at the front ends of the two screws. There are two toothed wrench mechanisms, symmetrically arranged. Tightening the screws causes the anti-slip pads to press against the wrench arms for fixation; rotating the limiting plates moves the screws away from the screw holes, facilitating the installation and removal of the toothed wrench, achieving the purpose of combined use with the tubing wrench. A tension spring tightens each pair of arc clamps to hold and fix one end of the tubing, facilitating inspection and maintenance operations.
[0004] The above-mentioned toothed plate has the following problems during installation: When disassembling the toothed plate, the screw needs to be twisted. The thread connection between the screw and the thread groove is shallow. If the screw is not twisted too many times, it may cause the threaded rod to separate from the thread groove, causing the screw to fall off and affecting the subsequent installation of the toothed plate. The screw needs to be added later, which increases the installation cost.
[0005] Therefore, it is necessary to invent a tubing wrench with a combined jaw plate to solve the above problems. Utility Model Content
[0006] The purpose of this utility model is to provide a tubing wrench with a combined toothed plate to solve the problem mentioned in the background art that when disassembling the toothed plate, it is necessary to twist the screw. The thread connection between the screw and the thread groove is shallow. If the screw is not twisted too many times, it may cause the threaded rod to separate from the thread groove, causing the screw to fall off and affecting the subsequent installation of the toothed plate. The screw needs to be added later, which increases the installation cost.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a hydraulic pipe wrench with a combined jaw plate, comprising a wrench body, a jaw plate mounted on the outside of the wrench body, and an mounting block fixedly mounted on the back of the jaw plate, the mounting block being matched and connected to a pre-reserved mounting groove inside the wrench body, a threaded rod being threadedly connected to a threaded groove one pre-reserved inside the wrench body, the threaded rod being anti-disengagement connected to the threaded groove one through an anti-disengagement component, a dial being fixedly mounted on one end of the threaded rod, and the other end of the threaded rod being threadedly connected to a threaded groove two pre-reserved inside the mounting block.
[0008] Preferably, two jaw plates are provided, and the two jaw plates are installed at the two ends of the clamp body that are symmetrical to each other.
[0009] Preferably, the mounting block is square, and the outer wall of the mounting block is attached to the inner wall of the mounting groove to achieve a movable match. The mounting groove, threaded groove one, and threaded groove two are connected to each other, so that the threaded rod that is threaded to the clamp body can be threaded to the threaded groove two reserved inside the mounting block to complete the installation of the jaw plate and the clamp body.
[0010] Preferably, the anti-disengagement component includes an annular groove pre-set inside the threaded groove, and an annular block is rotatably installed inside the annular groove. The connecting rod fixedly connected to the inner wall of the annular block and the limiting groove reserved inside the threaded rod achieve a movable match, ensuring the anti-disengagement connection between the threaded rod and the clamp body. This eliminates the need to install a threaded rod when installing a new jaw plate, saving installation costs.
[0011] Preferably, there is a gap between the inner ring wall of the annular block and the opening of the annular groove, and the inner ring wall of the annular block does not contact the outer thread of the threaded rod, so as to ensure that the annular block rotates synchronously with the threaded rod without affecting the rotation of the threaded rod.
[0012] Preferably, the outer wall of the connecting rod is in contact with the inner wall of the limiting groove to achieve a sliding connection, and both ends of the limiting groove are closed to ensure that the connecting rod and the threaded rod are connected without detachment.
[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0014] 1. This utility model matches the mounting block fixedly installed on the back of the jaw plate with the pre-reserved mounting groove inside the clamp body, and then turns the dial to adjust the rotation of the threaded rod so that the threaded rod rotates and moves in position to achieve threaded connection with the second threaded groove inside the mounting block, thereby completing the installation of the jaw plate. Subsequently, turning the dial in the opposite direction causes the threaded rod to rotate and move in position, so that the threaded rod separates from the second threaded groove, thereby completing the disassembly of the jaw plate.
[0015] 2. When the dial rotates and causes the threaded rod to move and change position, the connecting rod and the pre-reserved limiting groove inside the threaded rod engage to effectively ensure the threaded rod and the clamp body are not disengaged. This means that when installing a new die plate, there is no need to add a threaded rod, saving installation costs. Attached Figure Description

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0024] This utility model provides, for example Figure 1-4 The oil pipe wrench with a combined jaw plate shown includes a wrench body 1, a jaw plate 2 mounted on the outside of the wrench body 1, and an mounting block 3 fixedly mounted on the back of the jaw plate 2. The mounting block 3 is matched and connected to a pre-reserved mounting groove 4 inside the wrench body 1. A threaded rod 5 is threadedly connected to a pre-reserved threaded groove 6 inside the wrench body 1. The threaded rod 5 and the threaded groove 6 are connected to each other by an anti-disengagement component 8. A dial 9 is fixedly mounted on one end of the threaded rod 5, and the other end of the threaded rod 5 is threadedly connected to a pre-reserved threaded groove 7 inside the mounting block 3.
[0025] By matching the mounting block 3 fixedly installed on the back of the jaw plate 2 with the pre-reserved mounting slot 4 inside the clamp body 1, and then turning the dial 9 to adjust the rotation of the threaded rod 5, the threaded rod 5 rotates and moves to a position, achieving a threaded connection with the second threaded groove 7 inside the mounting block 3, thus completing the installation of the jaw plate 2. Subsequently, turning the dial 9 in the opposite direction causes the threaded rod 5 to rotate and move to a position, causing the threaded rod 5 to separate from the second threaded groove 7, thus completing the disassembly of the jaw plate 2. The threaded rod 5 and the first threaded groove 6 are connected by an anti-detachment component 8 to prevent the threaded rod 5 from falling off, allowing the threaded rod 5 to be reused and saving installation costs.
[0026] Two toothed plates 2 are provided, and the two toothed plates 2 are installed at the two ends of the clamp body 1 respectively.
[0027] The mounting block 3 is square, which ensures that the toothed plate 2 will not rotate after the mounting block 3 is installed in the mounting groove 4. The outer wall of the mounting block 3 is in contact with the inner wall of the mounting groove 4 to achieve a movable match. The mounting groove 4, threaded groove 6 and threaded groove 7 are connected to each other, so that the threaded rod 5, which is threaded to the clamp body 1, can be threaded to the threaded groove 7 reserved inside the mounting block 3, thus completing the installation of the toothed plate 2 and the clamp body 1.
[0028] The anti-detachment component 8 includes an annular groove 801 pre-set inside the threaded groove 6, and an annular block 802 is rotatably installed inside the annular groove 801. The connecting rod 803 fixedly connected to the inner wall of the annular block 802 is movably matched with the limiting groove 804 reserved inside the threaded rod 5. The outer wall of the connecting rod 803 is attached to the inner wall of the limiting groove 804 to achieve a sliding connection. Both ends of the limiting groove 804 are closed to ensure the anti-detachment connection between the connecting rod 803 and the threaded rod 5.
[0029] There is a gap between the inner ring wall of the annular block 802 and the groove opening of the annular groove 801, and the inner ring wall of the annular block 802 does not contact the outer thread of the threaded rod 5, so as to ensure that the annular block 802 rotates synchronously with the threaded rod 5 without affecting the rotation of the threaded rod 5.
[0030] When the dial 9 is turned, the threaded rod 5 rotates, which in turn causes the connecting rod 803 to rotate. The connecting rod 803 then causes the annular block 802, which is fixedly connected to it, to rotate inside the annular groove 801. At the same time, when the position of the threaded rod 5 changes due to rotation, the connecting rod 803 and the pre-reserved limiting groove 804 inside the threaded rod 5 engage in a movable fit, effectively ensuring the anti-disengagement connection between the threaded rod 5 and the clamp body 1. This means that when installing a new toothed plate 2, there is no need to use the threaded rod 5 again, saving installation costs.
[0031] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
