Description

Technical Field

[0001] The utility model relates to the technical field of pipeline connection, in particular to a disassembly device for a pipeline connector. Background Art

[0002] When two pipes are connected, pipe connectors are usually used, and pipe connectors are generally fixed with bolts. When some pipes are aged or rusted, the pipe connectors need to be disassembled, such as short-circuit, union, valve and other threaded connection square and hexagonal bodies. Sometimes, the installation position of some pipes and pipe connectors is very unreasonable, which may be blocked by the upper and lower water pipes or very close to the wall. The use of conventional wrenches generally cannot reach here for repair due to the small space. Even if it is stuck, there will be obstacles around the bolts that cannot be removed. The long wrench cannot rotate the wrench at a large angle, which brings great difficulties to maintenance and replacement. It may also accidentally hurt your fingers. In most cases, it cannot be disassembled, affecting the replacement and maintenance of the pipeline. For this reason, we designed a disassembly device for pipe connectors. Utility Model Content

[0003] In order to solve the technical problem that a differential return wrench cannot disassemble a pipe connector located in a small space, the utility model provides a disassembly device for the pipe connector.

[0004] The utility model is implemented by the following technical scheme: a disassembly device for a pipe connector, comprising a fixed clamp portion, a widened portion extending forward from the lower portion of the fixed clamp portion, a movable clamp portion slidingly arranged on the widened portion forward and backward, a gripping rod rotatably mounted on the right side surface of the widened portion, and an extended portion being arranged at the left end of the gripping rod, and an anti-slip sleeve being arranged on the outer ring surface of the extended portion.

[0005] As a further improvement of the above scheme, the front surface of the widened part is recessed toward the rear to form an installation groove, and sliding grooves are formed through the upper and lower sides of the installation groove. A mounting slide block is provided at the right end of the movable jaw part, and the mounting slide block is slidably placed in the mounting slide groove. The movable jaw part can be slidably installed in the widened part of the fixed jaw part through the mounting slide groove, and the distance between the fixed jaw part and the movable jaw part can be adjusted, which is suitable for bolts and nuts of various sizes.

[0006] As a further improvement of the above scheme, a locking bolt is sleeved on the mounting slide block, the upper end of the locking bolt is placed above the widened portion and is threadedly connected with a nut, and the lower end of the locking bolt is placed below the widened portion. After the sliding block is placed inside the mounting groove, the locking bolt is passed through from bottom to top, and the locking nut is screwed on top of the locking bolt to fix it, and the distance between the fixed jaw part and the movable jaw part can be adjusted as needed.

[0007] As a further improvement of the above solution, a connecting shaft block is integrally provided on the right side of the widened portion, a deflection shaft seat is provided on the left end of the gripping rod, and the deflection shaft seat is movably mounted on the connecting shaft block by bolts, and circular holes are formed through the connecting shaft block and the front and rear sides of the deflection shaft seat, the bolts pass through the circular holes from front to back and are screwed with nuts, and the deflection shaft seat can rotate with the bolts as the axis;

[0008] The widened portion is located at the left side of the connecting shaft block and a contact notch is formed by cutting away the portion. After the deflection shaft seat is rotated, the upper surface can contact the contact notch. At this time, the deflection angle of the entire grip is greater than 90 degrees. The user can apply a force toward the lower left, so that the grip is not easily deflected to the right when rotating the device.

[0009] As a further improvement of the above solution, the left end cross-section of the deflection shaft seat is a semicircular structure, and the left end of the deflection shaft seat is tangent to the right side surface of the widened portion, so that the deflection shaft seat will not be interfered during normal rotation.

[0010] As a further improvement of the above-mentioned solution, the right side surface of the grip rod is recessed toward the left to form an extended screw groove, and the left end of the extended part is integrally formed with an extended screw rod, which is threadedly connected in the extended screw groove. The overall length between the grip rod and the anti-slip sleeve can be lengthened as needed, thereby being suitable for wider or deeper positions in the pipeline.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. The utility model rotatably connects the fixed jaw part and the movable jaw part with the grip rod, and the grip rod can be rotated upward 90 degrees as needed, thereby reducing the overall length of the fixed jaw part and the grip rod, so that it can penetrate into a smaller space and loosen the nut, and the extended part and the extended screw rod are arranged, so that the overall length can be increased as needed, and it can be used in a deeper position;

[0020] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0021] Example:

[0022] Please combine Figure 1-Figure 4 A disassembly device for a pipe connector of this embodiment includes a fixed clamp part 1, a widened part 11 is formed by extending forward from the bottom of the fixed clamp part 1, a movable clamp part 2 is slidably arranged on the widened part 11, a grip rod 4 is rotatably installed on the right side surface of the widened part 11, and an extended part 5 is arranged at the left end of the grip rod 4, and an anti-slip sleeve 6 is arranged on the outer ring surface of the extended part 5.

[0023] The front surface of the widened portion 11 is recessed toward the rear to form an installation groove 13, and the upper and lower sides of the installation groove 13 are penetrated by sliding grooves 12. A mounting slide block 21 is provided at the right end of the movable jaw 2, and the mounting slide block 21 is slidably placed in the mounting groove 13. The movable jaw 2 can be slidably installed in the widened portion 11 of the fixed jaw 1 through the mounting groove 13, and the distance between the fixed jaw 1 and the movable jaw 2 can be adjusted, which is suitable for bolts and nuts of various sizes.

[0024] A locking bolt 7 is sleeved on the mounting slide block 21, the upper end of the locking bolt 7 is placed above the widened portion 11 and is threadedly connected with a nut, and the lower end of the locking bolt 7 is placed below the widened portion 11. After the sliding block is placed in the mounting slide groove 13, the locking bolt 7 is passed from bottom to top, and the locking nut is screwed on the top of the locking bolt 7 to fix it, and the distance between the fixed jaw part 1 and the movable jaw part 2 can be adjusted as needed.

[0025] The right side of the widened portion 11 is integrally provided with a connecting shaft block 3, and the left end of the grip rod 4 is provided with a deflection shaft seat 41, and the deflection shaft seat 41 is movably mounted on the connecting shaft block 3 by bolts, and circular holes are formed through the connecting shaft block 3 and the front and rear sides of the deflection shaft seat 41, and the bolts pass through the circular holes from front to back and are screwed with nuts, and the deflection shaft seat 41 can rotate with the bolts as the axis;

[0026] The widened portion 11 is located at the left side of the connecting shaft block 3 and a contact notch 14 is formed by cutting away the portion. After the deflection shaft seat 41 is rotated, the upper surface can contact the contact notch 14. At this time, the deflection angle of the entire handle 4 is greater than 90 degrees. The user can apply a force toward the lower left, so that the handle 4 is not easily deflected to the right when rotating the device.

[0027] The left end cross section of the deflection shaft seat 41 is a semicircular structure, and the left end of the deflection shaft seat 41 is tangent to the right side surface of the widened portion 11 , so that the deflection shaft seat 41 will not be interfered during normal rotation.

[0028] The right side surface of the grip rod 4 is recessed toward the left to form an extended screw groove 42, and the left end of the extended portion 5 is integrally formed with an extended screw rod 51, which is threadedly connected in the extended screw groove 42. The overall length between the grip rod 4 and the anti-slip sleeve 6 can be lengthened as needed, thereby being suitable for wider or deeper positions in the pipeline.

[0029] The implementation principle of the disassembly device of a pipe connector in the embodiment of the present application is as follows: when disassembling the pipe connector at a location with a small space, the grip rod 4 and the extension part 5 are deflected upward as a whole, and the deflection shaft seat 41 of the grip rod 4 is brought into contact with the contact notch 14. At this time, the entire width of the fixed jaw part 1 and the grip rod 4 is small, so that it can be placed in a small space. Then, the spacing between the fixed jaw part 1 and the movable jaw part 2 is adjusted according to the actual size of the bolt. Specifically, the locking nut is loosened, and the movable jaw part 2 can be moved forward or backward. After the handle 4 is in the proper position, the locking nut can be tightened again, and then the intermittent clamp between the fixed jaw part 1 and the movable jaw part 2 can be connected to the nut, and the gripping rod 4 can be turned. At this time, the nut on the pipe connecting piece can be loosened, and the pipe connecting piece can be disassembled. At the same time, when the gripping rod 4 is rotated, the deflection shaft seat 41 of the gripping rod 4 contacts the contact notch 14. At this time, the deflection angle of the entire gripping rod 4 is greater than 90 degrees. The user can apply a force downward to the left, so that the gripping rod 4 is not easy to deflect to the right when the device is rotated, thereby improving stability.

[0030] By rotatably connecting the fixed jaw part 1 and the movable jaw part 2 with the grip rod 4, the grip rod 4 can be rotated upward by 90 degrees as required, thereby reducing the overall length of the fixed jaw part 1 and the grip rod 4, so that it can penetrate into a smaller space and loosen the nut, and the extended part 5 and the extended screw 51 are arranged in combination, so that the overall length can be increased as required, and it can be applied to a deeper position;

[0031] The device has a simple overall structure and an overall modular design. It can be quickly assembled and disassembled as needed. It is suitable for a variety of scenarios and bolts and nuts of various sizes and is highly practical.

[0032] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
