Description

Technical Field

[0001] This utility model relates to the field of fastener disassembly and assembly technology for mechanical equipment, and specifically to a fastener rotation and disassembly device for mechanical assembly. Background Technology

[0002] In manual operation and machining, rotary operation is a common method for tightening or loosening fasteners such as bolts and nuts, and is widely used in equipment installation, repair and daily maintenance.

[0003] However, existing rotary tools still have many limitations in practical applications. For example, some tools apply force in an unreasonable way during operation, especially in confined spaces or restricted working environments, making it difficult for operators to apply force effectively, resulting in low work efficiency. At the same time, existing tools generally have poor adaptability; usually, one tool can only match fasteners of a specific size or type. To cope with different specifications of work objects, operators need to carry multiple tools, increasing labor burden and operating costs. In addition, some rotary tools have complex structural designs, which not only increase manufacturing costs but also bring inconvenience to later maintenance and repair. Therefore, there is an urgent need to develop a rotary operating tool with a simple structure, convenient operation, and strong adaptability to overcome the above-mentioned defects. Summary of the Invention

[0004] In view of the shortcomings of existing rotary tools, such as inconvenience in applying force and poor adaptability, this utility model provides a mechanical assembly device that can flexibly adjust the direction and angle of force application, facilitate operation, and is adaptable to fasteners such as bolts and nuts of various specifications for rotation and disassembly.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: A fastener rotation and disassembly device for mechanical assembly includes a main body cylinder and a disassembly assembly. The disassembly assembly includes at least two disassembly rods, the ends of which are provided with disassembly ends that mate with bolts or nuts. The main body cylinder is a cylindrical structure with an operating handle detachably mounted on its side, a top cover threadedly connected to its top, and a connecting post on its bottom surface that mates with the disassembly rods. The disassembly rods achieve quick disassembly and assembly by engaging with the connecting post.

[0006] In use, select the appropriate disassembly rod according to the specifications of the fastener to be operated, so that its disassembly end matches the bolt or nut to be disassembled. Then, quickly connect and fix the disassembly rod to the connecting post at the bottom of the main cylinder. Then, install the operating handle on the side of the main cylinder according to the specific conditions of the working space. By rotating the operating handle, the main cylinder and the connected disassembly rod will rotate synchronously, thereby realizing the fastening or disassembly of the fastener. When it is necessary to change to a different specification of fastener, the current disassembly rod can be quickly removed and replaced with a suitable disassembly rod. The disassembly and assembly device can be used while the operating handle is removed. At this time, rotating the main cylinder will drive the disassembly rod to perform the disassembly and assembly operation.

[0007] Furthermore, the main body cylinder has a connecting hole on its side, and a threaded sleeve is fixedly installed on its inner bottom surface. One end of the operating handle has a connecting plate that mates with the connecting hole. The bottom of the top cover has a threaded post corresponding to the threaded sleeve. The connecting plate has a through hole in the middle that mates with the threaded post. After the connecting plate passes through the connecting hole, it extends inward to abut against the inner wall of the main body cylinder. Then, the threaded post passes through the through hole and connects with the threaded sleeve. During installation, the connecting plate of the operating handle is inserted into the connecting hole on the side of the main body cylinder, and its inward extension abuts against the inner wall of the main body cylinder to form an effective limit. Then, the top cover is screwed into the top of the main body cylinder. The threaded post at its bottom passes through the through hole of the connecting plate in sequence and is threadedly connected with the inner threaded sleeve, thereby firmly clamping the connecting plate in the main body cylinder and reliably fixing the operating handle. This structure does not require additional fasteners such as screws or pins, simplifying the assembly process and improving the structural compactness. At the same time, during disassembly, only the top cover needs to be unscrewed to remove the connecting plate, which facilitates the quick replacement or storage of the operating handle and enhances the adaptability and flexibility of the tool in confined spaces.

[0008] Furthermore, the main body cylinder has external threads near the top; the top cover is a concave cover with internal threads on its inner wall that mate with the external threads of the main body cylinder. The top of the main body cylinder and the top cover are connected by threaded engagement, making the top cover securely installed and easy to disassemble, allowing for manual operation without additional tools. The concave shape of the top cover also enhances the connection. When the top cover is tightened, its threaded post at the bottom passes through the through hole and connects with the threaded sleeve inside the main body cylinder, thus reliably fixing the handle. This structure simplifies the assembly process, enhances connection stability, and improves the practicality and ease of operation of the device.

[0009] Furthermore, the outer wall of the connecting column is provided with external threads; the top of the disassembly rod is provided with a threaded hole that mates with the connecting column, and the disassembly end at the bottom is a countersunk hole for mates with bolts or nuts, or a screwdriver bit for mates with screws. The connecting column and the disassembly rod are connected by threads to achieve quick installation and disassembly, making the disassembly rod easy to replace, adaptable to various types and sizes of fasteners, improving the versatility of the tool, and the threaded connection structure is stable and reliable, effectively transmitting rotational torque, ensuring work efficiency and safety; the disassembly end at the bottom of the disassembly rod can be designed as a countersunk hole to accommodate bolts or nuts of different specifications, or adopt a screwdriver bit structure for disassembling and installing screws, facilitating selection during the disassembly and assembly process.

[0010] Furthermore, the connecting post is cross-shaped; the top of the disassembly rod is provided with a cross-shaped groove that mates with the connecting post. The disassembly rod and the main body are quickly connected via a cross-shaped insertion method. This method eliminates the need for threaded engagement; simply align the groove of the disassembly rod with the cross-shaped connecting post and insert it to complete the installation. This makes assembly and disassembly quicker and more convenient, especially suitable for work scenarios requiring frequent disassembly rod replacements. The cross-shaped connection structure effectively transmits torque, prevents slippage, and maintains good alignment and connection stability.

[0011] Furthermore, the length of the disassembly rod is shorter than the length of the main body tube, allowing the disassembly rod to be inserted into the main body tube. This shorter length allows for direct storage inside the main body tube after disassembly, utilizing the internal space to achieve integrated storage of the disassembly rod and the main body tube, preventing parts from scattering or being lost, and facilitating carrying and management.

[0012] Furthermore, the height of the main body cylinder ranges from 80mm to 120mm, and the diameter ranges from 30mm to 50mm. This size range ensures sufficient structural strength and operational stability while also taking into account portability and spatial adaptability. The reasonable height and diameter make the tool comfortable to hold and easy to apply force, and can accommodate components such as disassembly rods for internal storage. It is suitable for most assembly and maintenance operations in confined or narrow spaces, without affecting operational flexibility, and can effectively transmit torque.

[0013] Furthermore, the length of the operating handle ranges from 220mm to 250mm. This length range ensures sufficient lever arm to improve torque output while also taking into account operational flexibility and spatial adaptability. The longer handle facilitates the application of force, improving work efficiency, and is especially suitable for disassembling and assembling tighter or more resistant fasteners; while the overall length is still controlled within a reasonable range to avoid restrictions when operating in confined spaces.

[0014] Compared with the prior art, the present invention has the following advantages and beneficial effects: 1. This utility model, through its modular design of a main cylinder and replaceable detachable rods, achieves wide compatibility with various specifications of bolts and nuts, reducing the need for operators to carry multiple sets of tools, and lowering labor intensity and operating costs. The main cylinder has a simple structure, and the detachable rods are easy to replace, meeting the diverse needs of fastener disassembly and assembly for mechanical equipment, while improving the versatility and efficiency of the tools. The detachable operating handle allows for flexible adjustment of the force direction and operating angle in confined or narrow spaces, effectively improving the inconvenience of applying force with traditional tools. The overall structure is reasonably designed, with low manufacturing costs and simple maintenance, significantly improving the convenience and efficiency of mechanical assembly and maintenance operations.

[0015] 2. This device features a modular design with a main body and replaceable detachable rods, adapting to various fastener specifications and enhancing versatility. The detachable rods can be threaded or Phillips headed for quick replacement and can be stored inside the main body for easy carrying. The operating handle is fixed to the top cover and threaded sleeve via a connecting plate, eliminating the need for additional tools and ensuring flexibility and reliability. The overall structure is compact, and the operating handle is of moderate length, balancing force application efficiency with space adaptability, making it suitable for operation in confined spaces and significantly improving ease of assembly and disassembly as well as work efficiency.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings.

[0022] Example 1: A fastener rotation and disassembly device for mechanical assembly includes a main body cylinder 1 and a disassembly assembly 2, wherein the disassembly assembly 2 includes at least two disassembly rods 21, and the ends of the disassembly rods 21 are provided with disassembly ends that mate with bolts or nuts; the main body cylinder 1 is a cylindrical structure, with an operating handle 3 detachably installed on the side, a top cover 11 threadedly connected to the top, and a connecting post 12 that mates with the disassembly rods 21 on the bottom surface, and the disassembly rods 21 are connected to the connecting post 12 to achieve quick disassembly and assembly.

[0023] In use, select the appropriate disassembly rod 21 according to the specifications of the fastener to be operated, so that its disassembly end matches the bolt or nut to be disassembled. Then, quickly connect and fix the disassembly rod 21 to the connecting post 12 at the bottom of the main body cylinder 1. Then, install the operating handle 3 on the side of the main body cylinder 1 according to the specific conditions of the working space. By rotating the operating handle 3, the main body cylinder 1 and the connected disassembly rod 21 will rotate synchronously, thereby realizing the fastening or disassembly of the fastener. When it is necessary to change the fastener of different specifications, the current disassembly rod 21 can be quickly removed and replaced with a suitable disassembly rod 21. The disassembly and assembly device can be used while the operating handle 3 is removed. At this time, rotating the main body cylinder 1 will drive the disassembly rod 21 to perform the disassembly and assembly operation.

[0024] Example 2: Unlike Example 1, the main body cylinder 1 has a connecting hole on its side and a threaded sleeve 13 is fixedly provided on its inner bottom surface. One end of the operating handle 3 is provided with a connecting plate 31 that mates with the connecting hole. The bottom of the top cover 11 is provided with a threaded post 14 corresponding to the threaded sleeve 13. The connecting plate 31 has a through hole 32 in the middle that mates with the threaded post 14. After the connecting plate 31 passes through the connecting hole, it extends inward and abuts against the inner wall of the main body cylinder 1. Then the threaded post 14 passes through the through hole 32 and connects with the threaded sleeve 13. During installation, the connecting plate 31 of the operating handle 3 is inserted into the connecting hole on the side of the main body cylinder 1, and its inward extension abuts against the inner wall of the main body cylinder 1 to form an effective limit. Then, the top cover 11 is screwed into the top of the main body cylinder 1, and the threaded post 14 at its bottom passes through the through hole 32 of the connecting plate 31 and is threadedly connected to the internal threaded sleeve 13, thereby firmly clamping the connecting plate 31 in the main body cylinder 1 and reliably fixing the operating handle 3. This structure does not require additional fasteners such as screws or pins, which simplifies the assembly process and improves the structural compactness. At the same time, during disassembly, only the top cover 11 needs to be unscrewed to remove the connecting plate 31, which facilitates the quick replacement or storage of the operating handle 3 and enhances the adaptability and flexibility of the tool in confined spaces.

[0025] The main body cylinder 1 has an external thread near its top; the top cover 11 is a concave cover with an internal thread on its inner wall that mates with the external thread of the main body cylinder 1. The main body cylinder 1 and the top cover 11 are connected by a threaded connection, making the top cover 11 securely installed and easy to disassemble, allowing for manual operation without additional tools. The concave shape of the top cover 11 also enhances the connection. When the top cover 11 is tightened, its threaded post 14 passes through the through hole 32 and connects with the threaded sleeve 13 inside the main body cylinder 1, thus reliably fixing the handle. This structure simplifies the assembly process, enhances connection stability, and improves the practicality and ease of operation of the device.

[0026] The length of the disassembly rod 21 is less than the length of the main body cylinder 1, and the disassembly rod 21 can be inserted into the main body cylinder 1. The length of the disassembly rod 21 is less than the length of the main body cylinder 1, so that it can be directly stored inside the main body cylinder 1 after disassembly. By utilizing the internal space of the main body cylinder 1, the disassembly rod 21 and the main body cylinder 1 can be integrated for storage, avoiding the scattering or loss of parts and making it convenient to carry and manage.

[0027] Example 3: The difference from Example 2 is that the connecting post 12 has external threads on its outer wall; the top of the disassembly rod 21 has a threaded hole that mates with the connecting post 12, and the bottom disassembly end is a countersunk hole 22 for bolts or nuts, or a screwdriver bit 23 for screws. The connecting post 12 and the disassembly rod 21 are connected by threads to achieve quick installation and disassembly, making the disassembly rod 21 easy to replace, adaptable to various types and sizes of fasteners, improving the tool's versatility. The threaded connection structure is stable and reliable, effectively transmitting rotational torque, ensuring work efficiency and safety. The disassembly end at the bottom of the disassembly rod 21 can be designed as a countersunk hole 22 to accommodate bolts or nuts of different specifications, or use a screwdriver bit 23 structure for screw installation and removal, facilitating selection during the installation and removal process.

[0028] The height of the main body cylinder 1 ranges from 80mm to 120mm, and the diameter ranges from 30mm to 50mm. This size range ensures sufficient structural strength and operational stability while also taking into account portability and spatial adaptability. The reasonable height and diameter make the tool comfortable to hold and easy to apply force, and can accommodate components such as the disassembly rod 21 for internal storage. It is also suitable for most assembly and maintenance operations in small or restricted spaces, without affecting operational flexibility, and can effectively transmit torque.

[0029] The length of the operating handle 3 ranges from 220mm to 250mm. This length range ensures sufficient lever arm to improve torque output while also taking into account operational flexibility and space adaptability. The longer handle facilitates the application of force, improving work efficiency, and is especially suitable for disassembling and assembling tighter or more resistant fasteners; while the overall length is still controlled within a reasonable range to avoid restrictions when operating in confined spaces.

[0030] Example 4: Unlike Example 2, the connecting post 12 is cross-shaped; the top of the disassembly rod 21 has a cross-shaped groove 17 that mates with the connecting post 12, and the bottom disassembly end is a countersunk hole 22 for mates with bolts or nuts, or a screwdriver bit 23 for mates with screws. The disassembly rod 21 and the main body cylinder 1 are quickly connected via a cross-shaped insertion method. This method does not require threaded engagement; simply align the groove of the disassembly rod 21 with the cross-shaped connecting post 12 and insert it to complete the installation. Disassembly and assembly are quicker and more convenient, especially suitable for work scenarios requiring frequent replacement of the disassembly rod 21. The cross-shaped connection structure effectively transmits torque, prevents slippage, and maintains good alignment and connection stability.
