Abstract
Description
Technical Field
[0001] This invention relates to a multifunctional modular fastening and disassembly device, which can be used to disassemble and assemble various types of screws, nuts, bolts, etc. Background Technology
[0002] In routine equipment disassembly and maintenance, tools such as box wrenches, open-end wrenches, and Allen wrenches are frequently used. A large number of tools of various types are needed to complete the disassembly and assembly of large and complex components. Due to the variety of tools, and the fact that each type has multiple sizes, if the dimensions of the components being disassembled or assembled are not accurately known, it often results in carrying the wrong tool or carrying too many unnecessary tools. In practice, multiple types of tools are frequently switched, especially in the specialized field of repairing large radar antennas. These antennas have complex structures, numerous components, and various disassembly and assembly parts with different specifications and standards. Furthermore, the antenna installation locations are often far from work and living areas to avoid radiation. When inspecting and maintaining multiple antennas, the more tools carried, the greater the weight, causing considerable inconvenience for the personnel carrying the tools. Moreover, the time spent on collecting and organizing tools after use, and the need for storage space, are all significant factors. Additionally, with the upgrading of new equipment, the need to purchase new tool kits leads to substantial financial expenditure.
[0003] Currently, various types and sizes of fasteners require a variety of specialized disassembly and assembly tools. Because these tools are specialized, they cannot be used with other types of fasteners, resulting in limited functionality. When disassembling and assembling large and complex equipment, multiple tools are needed, leading to inconvenience and diminishing the advantages of using them effectively. The sheer number of tools required also degrades the usability of the tools. While some multi-functional disassembly and assembly tools exist, they essentially only allow for the replacement of different heads with the same type of fastener, offering more convenience than dedicated wrenches, but still have significant limitations. This invention can completely disassemble and assemble various types and sizes of fasteners, increasing emergency response capabilities, improving work efficiency, and enhancing the work experience. Summary of the Invention
[0004] The purpose of this invention is to address the shortcomings of existing tools by providing a multifunctional modular assembly and disassembly device.
[0005] This invention utilizes an adjustable ring knob on the connecting rod to move replacement heads mounted at both ends of the rod towards either a double hexagonal jaw or a movable jaw, according to the size of the component being disassembled or assembled. This achieves locking and securing of the component, and external force is then applied via a handle to complete the disassembly or assembly. The double hexagonal jaw or movable jaw can be flexibly selected based on the environment, space, and shape of the component. It is recommended that this device be made of chrome vanadium steel. This device is simple, flexible, reliable, practical, and portable. It can adapt to the disassembly and assembly needs of most work and life scenarios and can replace most different types of tools.
[0006] The multi-functional modular disassembly and assembly device in this solution mainly includes a handle holder, an adjustable connecting rod, movable jaws, and a replacement head.
[0007] The main body of the handle frame is a hollow handle (10); one end of it is connected to a double hexagonal bayonet (11), and an adjustment ring hole (9) is opened in the middle; the double hexagonal bayonet (11) is formed by two regular hexagons that are concentrically offset by 30°. Since the inner hole of its working part has 12 corners, which are formed by two regular hexagonal holes that are 30° apart, the handle can be changed by turning the wrench by 30°. The head is closed, the outer ring wall is smooth and the structure is thin, and the locking torque is large. Therefore, it is suitable for bolts, screws, nuts and other occasions with relatively small surrounding space, as well as devices with a narrow outer ring, open end and end and smooth without a force point, similar to pipes.
[0008] The adjustable connecting rod is placed in the hollow cavity of the handle (10) and is slightly longer than the handle (10). It is flattened on the opposite side of the cylinder to form a flat adjustable connecting rod (16). The adjustable connecting rod has embedded hexagonal quick-release holes (13) at both ends and threads are machined on the outer wall of the middle part. The adjusting ring (15) is located on the threads and can be rotated clockwise and counterclockwise through the adjusting ring hole (9) on the handle (10), thereby realizing the movement of the adjustable connecting rod (16).
[0009] The main body of the movable jaw is inverted L-shaped, which mainly includes a flat cylindrical opening adjustment rod (6) and a jaw (1) arranged perpendicular to it; the opening adjustment rod (6) of the movable jaw is fixed by the fixing seats (7) and (8) on the handle frame. The fixing seats (7) and (8) on the handle frame are located on the outer wall of the other end opposite to the double hexagonal jaw (11) on the handle grip (10); there is a thread (2) on the flat column of the opening adjustment rod (6), and the opening adjustment ring (4) is located between the two fixing seats and is installed on the opening adjustment rod (6) by the thread (2). The size of the opening of the movable jaw is realized by rotating the opening adjustment ring (4) clockwise and counterclockwise, so as to adjust the biting force of the disassembly and assembly of the device.
[0010] The replacement head matches the hexagonal quick-release holes (13) at both ends of the adjustable connecting rod. It consists of a solid hexagonal quick-connect connector (18) and a meshing surface (17). The quick-connect connector (18) is directly embedded in the embedded hexagonal quick-release holes (13) at both ends of the adjustable connecting rod (16). This solution is designed with two types of quick-connect connectors: quick-connect connector (A) and quick-connect connector (B). The quick-connect connector (A) includes two meshing surfaces (17) forming a certain angle. The quick-connect connector (B) is a meshing surface (17) with a tooth structure. At the same time, commercially available quick-connect connectors can be used as replacements. The appropriate quick-connect connector is selected according to the shape of different fasteners, which has strong versatility. The uniquely designed comprehensive quick-connect connector in this solution has met the application scenarios in most cases and has good performance. The hexagonal quick-connect connector (18) moves radially with the adjustable connecting rod (16) to adjust the meshing force of the double hexagonal jaw (11) or the movable jaw.
[0011] The multi-functional modular assembly and disassembly device can select multiple working modes, and the modes are diverse. Two examples are listed below:
[0012] 1) In a limited space where the working environment and the longitudinal (parallel) space of the disassembly and assembly device are narrow and there are obstacles on one or even three sides, use the double hexagonal bayonet to fit the device to be disassembled, rotate the adjustment ring in the adjustment hole (9) of the handle, and drive the adjustable connecting rod (16) and the quick-release connector (18) in the quick-release hole (13) to move into the double hexagonal bayonet (11). When the engagement surface (17) of the quick-release connector is locked with the device to be disassembled and the outer ring is tightly fitted with the inner side of the double hexagonal bayonet, apply external force by holding the other side of the handle. The disassembly and assembly of the fastener can be achieved by rotating at a small angle (30°) according to the space gap.
[0013] 2) When the working environment and the horizontal (vertical) space of the disassembly and assembly device are narrow and the double hexagonal jaws (11) cannot pass through the limited space, the size of the movable jaws can be initially adjusted according to the size of the disassembled and assembled parts, and the disassembled and assembled parts can be clamped from the upper or lower end of the disassembled and assembled parts. Then, rotate the adjusting ring in the adjustment hole (9) of the handle to drive the adjustable connecting rod (16) and the quick-release connector (18) in the quick-release hole (13) to move in the direction of the movable jaws. When the meshing surface (17) of the quick-release connector is locked with the disassembled device and the other end is tightly locked with the jaws of the movable jaws, apply external force by holding the other side of the handle. The fasteners can be disassembled and assembled according to the space gap.
[0014] In addition, the replacement head designed for this device ( Figure 4Types A and B are not currently available on the market. They are unique to this device. Type A has a beveled design for better assembly and disassembly of hexagonal nuts. Type B has a die design, which increases the clamping force of fasteners by using neat and numerous dies. Both types of meshing surfaces are also well-suited for irregularly shaped, damaged, and irregular fasteners.
[0015] The beneficial effects of this invention are as follows: It adopts a multi-functional modular disassembly and assembly device, which is designed based on the actual problems encountered during the maintenance of large and complex equipment. It can effectively solve the problems encountered in disassembly and assembly operations. The tool device formed by simple modular design has a simple structure, novel ideas, and is small and convenient to carry. It realizes the functions of a variety of special tools, solves the problem of strict requirements on tools due to the differences in different types of components, and effectively solves the problems of inconvenience in carrying a large number of tools and climbing while carrying them. It improves the working efficiency, enhances the quality of use, and is suitable for wide-ranging promotion and application. Attached Figure Description

Detailed Implementation

The head is closed, the outer ring wall is smooth and the structure is thin, and the locking torque is large. Therefore, it is suitable for bolts, screws, nuts and other occasions with relatively small surrounding space, as well as devices with a narrow outer ring, open end and end and smooth without a force point, similar to pipes.
[0025] The adjustable connecting rod is placed in the hollow cavity of the handle (10) and is slightly longer than the handle (10). It is flattened on the opposite side of the cylinder and presents a flat threaded body (16).

The adjusting ring (15) is located in the threaded section and can be rotated clockwise and counterclockwise through the adjusting ring hole (9) on the handle (10), thereby realizing the movement of the connecting rod (16).
[0026] The main body of the movable jaw is inverted L-shaped, which mainly includes a flat cylindrical opening adjustment rod (6) and a jaw (1) arranged perpendicular to it; the opening adjustment rod (6) of the movable jaw is fixed by the fixed seats (7) and (8) on the handle frame, and the fixed seats (7) and (8) on the handle frame are located on the outer wall of the other end opposite to the double hexagonal jaw (11) on the handle grip (10); there is a thread (2) on the flat column of the opening adjustment rod (6), and the opening adjustment ring (4) is located between the two fixed seats and is installed on the opening adjustment rod (6) by the thread (2). The size of the opening of the movable jaw is realized by rotating the opening adjustment ring (4) clockwise and counterclockwise, so as to realize the adjustment of the biting force of the disassembly and assembly of the device.
[0027] The replacement head matches the hexagonal quick-release seats (13) at both ends of the adjustable connecting rod. It consists of a solid hexagonal quick-connect connector (18) and a meshing surface (17). The quick-connect connector (18) is directly embedded in the embedded hexagonal quick-release holes (13) at both ends of the adjustable connecting rod (16). In this solution, there are two types of quick-connect connectors: quick-connect connector (A) and quick-connect connector (B). The quick-connect connector (A) includes two meshing surfaces (17) forming a certain angle. The quick-connect connector (B) is a meshing surface (17) with a tooth structure. At the same time, commercially available quick-connect connectors can also be used for replacement. The appropriate quick-connect connector is selected according to the shape of different fasteners, which has strong versatility. The uniquely designed comprehensive quick-connect connector in this solution has met the application scenarios in most cases and has good performance. The hexagonal quick-connect connector (18) moves radially with the adjustable connecting rod (16) to adjust the meshing force of the double hexagonal jaw (11) or the movable jaw.
[0028] The multi-functional modular assembly / disassembly device can operate in various modes, as listed below:
