Description

Technical Field

[0001] The utility model relates to a disassembly and assembly wrench, in particular to a disassembly and assembly wrench for machine repair fitters. Background Art

[0002] The information provided in this section is only background information related to the present disclosure, and it does not necessarily represent prior art.

[0003] A wrench is a commonly used installation and disassembly tool. It is a manual tool that uses the lever principle to twist bolts, screws, nuts, and other threaded fasteners with openings or socket holes for holding bolts or nuts. Wrenches are usually made of structural steel with carbon or alloy materials. Wrenches usually have openings or socket holes for holding bolts or nuts at one or both ends of the handle. When in use, an external force is applied to the handle along the thread rotation direction to twist the bolt or nut. The socket holes of existing wrenches are generally of fixed specifications or need to be adjusted actively, and cannot be directly applied to nuts of different specifications.

[0004] In the prior art, there is a wrench that can match nuts of different specifications by replacing the screwing head. However, the prior art solution requires replacing the screwing head, and the screwing head is prone to loss.

[0005] Therefore, a disassembly and assembly wrench for machine repair fitters that solves the above problems is needed.

[0006] It should be noted that the information disclosed in the above background art section is only used to enhance the understanding of the background of the present disclosure, and thus may include information that does not constitute prior art known to those of ordinary skill in the art. Summary of the Utility Model

[0007] Object of the Invention: The technical problem to be solved by the present utility model is to provide a disassembly and assembly wrench for machine repair fitters in view of the deficiencies of the prior art.

[0008] To solve the above technical problems, the present utility model discloses a disassembly and assembly wrench for machine repair fitters, including:

[0009] A rotating rod for hand-held operation; at one end of the rotating rod, there is an installation component, and different-sized screwing rings are provided in the installation component for sleeving on nuts of different sizes to be disassembled and assembled.

[0010] Further, the installation component includes:

[0011] An installation ring connected to the rotating rod, the inner circle of the installation ring is a hexagonal opening, and the size is the same as that of the corresponding nut to be disassembled and assembled;

[0012] One or more screwing rings are sequentially sleeved in the inner circle of the installation ring from large to small, and the inner circles of the screwing rings are all hexagonal openings, and the sizes are the same as those of the corresponding nuts to be disassembled and assembled.

[0013] Furthermore, an elastic cord is provided on the top surface of the mounting ring. The other end of the elastic cord is mounted on the top surface of the innermost screwing ring. The middle part of the elastic cord is connected to the top surfaces of all the screwing rings passed by, for restricting the upward movement of the screwing rings.

[0014] Furthermore, the elastic cord is fixedly connected to the mounting ring and the screwing rings through fixing bolts.

[0015] Furthermore, the height of the screwing ring is greater than that of the mounting ring, and the heights increase successively from outside to inside; a protruding portion is provided on the outer side surface of the top of the screwing ring, for preventing the screwing ring from moving downward.

[0016] Furthermore, there are 3 screwing rings, which are respectively, from outside to inside: a first-level screwing ring, a second-level screwing ring, and a third-level screwing ring.

[0017] Furthermore, a regulating sleeve is sleeved on one end of the rotating rod away from the mounting component, for adjusting the length of the rotating rod.

[0018] Furthermore, an adjusting bolt is provided on the regulating sleeve, for fixing the regulating sleeve.

[0019] Furthermore, the rotating rod is rotatably connected to the mounting component through a U-shaped frame;

[0020] The flat end of the U-shaped frame is fixedly connected to the side surface of the mounting component. One end of the rotating rod extends into the concave surface of the U-shaped frame and is connected through a rotating shaft.

[0021] Furthermore, a limiting block is provided on the top of the U-shaped frame, for restricting the rotation angle of the rotating rod.

[0022] Beneficial effects:

[0023] The utility model effectively overcomes the limitations of traditional wrenches when adapting to nuts of multiple specifications, without the need to frequently replace components, and significantly improves work efficiency and convenience, as follows:

[0024] 1. Enhanced versatility and flexibility: Through the design of hierarchically nested screwing rings (first-level to third-level screwing rings), this wrench can automatically adapt to nuts of various specifications, without the need to carry and replace multiple screwing heads, reducing the risk of pauses and component loss during work.

[0025] 2. Improved operational simplicity: By using the combination of the rotating rod and the adjusting screw, the user can adjust the position of the wrench through simple operations, enabling the wrench to automatically adapt to the nut size. This process does not require complex manual alignment or component replacement, simplifying the operation process.

[0026] 3. Spatial adaptability optimization: The design of the rotating rod enables the wrench to operate more flexibly in narrow spaces. When the angle of the rotating rod increases, it is especially suitable for working on bolts or nuts in restricted spaces, improving its practicality in complex mechanical repair scenarios.

[0027] 4. Labor-saving and high efficiency: Through the design of the limit block, it ensures that the nut can be effectively fixed when the downward pressure is appropriate. In combination with the pulling effect of the elastic rope, it not only helps the rotating rings of each layer to quickly reset, but also makes the entire tightening or loosening process more labor-saving, improving work efficiency.

[0028] 5. Maintaining component integrity: Since there is no need to frequently disassemble the rotating rings, this design helps to maintain the integrity of the wrench and reduce the possibility of component loss, extending the service life of the tool and reducing maintenance costs.

[0029] In summary, through its unique structural design, the present utility model not only solves the problem of adaptability to multi-specification nuts, but also significantly improves work efficiency, flexibility, and convenience of use, making it an important technological innovation in the field of mechanical repair.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0034] The present utility model provides a disassembly and assembly wrench for machine repair fitters. The technical solution adopted is as follows:

[0035] A disassembly and assembly wrench for machine repair fitters includes an installation ring 21, a first-level rotating ring 22 is embedded in the installation ring 21, a second-level rotating ring 23 is embedded in the first-level rotating ring 22, a third-level rotating ring 24 is embedded in the second-level rotating ring 23, a fixing bolt 25 is installed on the third-level rotating ring 24, an elastic rope 26 is installed on the installation ring 21, and the other end of the elastic rope 26 is connected to the fixing bolt 25.

[0036] On one side of the mounting ring 21, there is a U-shaped frame 13. A rotating rod 1 is rotatably mounted inside the U-shaped frame 13. An adjusting sleeve 11 is sleeved on the rotating rod 1, and an adjusting bolt 12 is mounted on the adjusting sleeve 11.

[0037] Fixing bolts 25 are mounted on the secondary screwing ring 23. Fixing bolts 25 are also mounted on the primary screwing ring 22. The upper ends of the primary screwing ring 22, the secondary screwing ring 23, and the tertiary screwing ring 24 are provided with outwardly protruding annular edges.

[0038] A limiting block 14 is mounted on the upper part of the U-shaped frame 13.

[0039] During operation, when the adjusting sleeve 11 is operated to drive the rotating rod 1, and when the rotating rod 1 rotates to near vertical, the rotating rod 1 contacts the limiting block 14, thereby driving the mounting ring 21 to press down on the nut part to be disassembled and assembled. When the mounting ring 21 presses down, the nut falls into the primary screwing ring 22, or the secondary screwing ring 23, or the tertiary screwing ring 24. When the specification of the nut corresponds to the inside of the primary screwing ring 22, or the secondary screwing ring 23, or the tertiary screwing ring 24, the screwing ring smaller than the corresponding one is lifted by the nut.

[0040] The elastic cord 26 pulls the tertiary screwing ring to facilitate the tertiary screwing ring 24 to press down the secondary screwing ring 23 and the primary screwing ring 22 to reset, thereby realizing the screwing of nuts of various specifications without the need to remove the screwing rings. When the angle of the rotating rod 1 increases, it is convenient to screw in a narrow area. When the angle of the rotating rod 1 decreases, the rotation radius increases, making it more labor-saving.

[0041] The present invention provides an idea and method for a machine repair fitter's disassembly and assembly wrench. There are many methods and ways to specifically implement this technical solution. The above description is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention. Each component not clearly defined in this embodiment can be realized by existing technologies.
