Description

Technical Field

[0001] This application relates to the field of instrument assembly and disassembly technology, specifically to a tool for rapid assembly and disassembly of instruments in confined spaces. Background Technology

[0002] Columnar instruments are common in various fields. The installation and disassembly of small columnar instruments rely on operators using screwdrivers to operate one by one. Small columnar instruments are usually fixed with four thin flathead screws and flat spring washers. When installing and disassembling small columnar instruments with four thin flathead screws and flat spring washers in a confined space, the following problems exist: (1) The space is very limited. Since the operation process is not visible, the operator needs to operate blindly, which leads to positioning difficulties and inconvenience in installation and disassembly; (2) The screwdriver can easily slip out of the screw slot, and it is difficult to maintain the upright position of the screw in the screw hole during installation. Once it is crooked, the installation will be stuck, and repeated adjustments will lead to low installation and disassembly efficiency; (3) Small fasteners, including screws, spring washers, and irregular flat washers, are very easy to fall off and are difficult to retrieve. Therefore, there is an urgent need to propose a tool for quick installation and disassembly of instruments in confined spaces to assist in the installation and disassembly of small columnar instruments in confined spaces.

[0023] This application provides a tool for quick assembly and disassembly of instruments in confined spaces, which solves the problems of difficult operation, low efficiency, and easy parts falling off when installing and disassembling small cylindrical instruments in confined spaces.

[0024] The technical solution in this application is to solve the above-mentioned technical problems, and the general idea is as follows:

[0025] Columnar instruments are common in various fields. The installation and disassembly of small columnar instruments rely on operators using screwdrivers to operate one by one. Small columnar instruments are usually fixed with four thin flathead screws and flat spring washers. When installing and disassembling small columnar instruments with four thin flathead screws and flat spring washers in a confined space, the following problems exist: (1) The space is very limited. Since the operation process is not visible, the operator needs to operate blindly, which leads to positioning difficulties and inconvenience in installation and disassembly; (2) The screwdriver is easy to slip out of the screw slot, and it is difficult to keep the screw upright in the screw hole for a long time during installation. Once it is crooked, the installation will be stuck, and repeated adjustments will lead to low installation and disassembly efficiency; (3) Small fasteners, including screws, spring washers, and irregular flat washers, are very easy to fall off and are difficult to find. Based on this, there is an urgent need to propose a tool for quick installation and disassembly of instruments in confined spaces to assist in the installation and disassembly of small columnar instruments in confined spaces; to ensure that the screws, spring washers, and flat washers are reliably matched with the instrument before operation, and to solve the problem of easy parts falling off.

[0026] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0027] The following is a description of a tool for quick assembly and disassembly of instruments in confined spaces provided in the embodiments of this application.

[0028] This application provides a tool for the rapid assembly and disassembly of instruments in confined spaces, such as... Figure 1 As shown, the instrument quick assembly / disassembly tool in the confined space includes a columnar structural body 1, the shape and size of which correspond to the shape of the instrument to be disassembled / assembled; the bottom of the structural body 1 is provided with a patterned groove and a claw is formed through the patterned groove.

[0029] Specifically, the patterned groove includes four recesses 2 spaced apart; the claws include four claws 3 arranged in an array, the four claws 3 corresponding to the corner area A along the circumference of the main body 1, and the claws 3 and the recesses 2 are alternately spaced one-to-one; the main body 1 has four through feeding holes B along its length for the assembly parts corresponding to the instrument to pass through, and each feeding hole B is adjacent to a corner area A; the area of ​​the feeding hole B adjacent to the patterned groove is provided with a threaded part to constrain the degree of freedom of movement of the assembly parts in space and to allow the assembly parts to pass through in one direction.

[0030] In the embodiments of this application, it can be understood that the instrument quick assembly and disassembly tool provided in this application matches the shape of the instrument to be disassembled and assembled. The bottom of the main body 1 is formed with a patterned groove and four claws 3 to stably dock with the instrument. The four claws 3 correspond to multiple corner areas A of the main body 1. The cooperation of the four claws 3 enables the assembly parts and the screw holes of the instrument to be accurately positioned.

[0031] Furthermore, the main body 1 of this application is provided with four feeding holes B along its own length. The feeding holes B provide a space for the assembly parts and screwdriver to move and operate. The threaded part in the feeding hole B can constrain the degree of freedom of movement of the assembly parts in space and allow the assembly parts to pass through in one direction. The problem of screwdriver slippage and easy misalignment of assembly parts is solved by the cooperation of the four feeding holes B. The dimensions of the disassembly and assembly tools provided in this application are closely matched with the instrument.

[0032] By using this disassembly and assembly tool, the assembled parts are reliably fitted into the instrument before operation, solving the problem of easy parts falling off; operators can efficiently disassemble and assemble small cylindrical instruments in confined spaces.

[0033] In one example, the feed hole B is elongated and has a circular cross-section at any point along its length. The assembled parts include screws and spring washers. In a confined space where operation is not visible, the screw and screwdriver pass through the feed hole B. The screwdriver is not easily slipped out of the screw slot, and the screw is kept upright in the screw hole during installation.

[0034] In some embodiments, the radial dimension of the feed hole B is greater than the radial dimension of the screw head, the length of the feed hole B is greater than the length of the screw, and the threaded portion is machined along the inner wall of the feed hole B and includes 2-6 turns of thread.

[0035] As can be understood in the embodiments of this application, the assembly parts include screws with relatively large head sizes. The feed hole B in this application needs to ensure that the assembly parts can pass through smoothly in one direction. At the same time, in order to reduce the problems of screwdriver slippage and misalignment of assembly parts when blindly operating the instrument in a confined space, the inner wall of the feed hole B is machined with several threads. In addition, besides setting threads on the inner wall of the feed hole B, barbs can also be set on the inner wall of the feed hole B. The size of the barbs must ensure that the assembly parts can pass through smoothly in one direction and be durable.

[0036] In some embodiments, the interior of the main body 1 is hollow to form a central through hole C, which is through the length of the main body 1.

[0037] In the embodiments of this application, it can be understood that, compared with the feed hole B, the central through hole C corresponds to the central area of ​​the main body 1 and its radial dimension is larger. By opening a through central through hole C in the central area of ​​the main body 1, materials can be saved and the weight of the disassembly and assembly tool can be reduced. The instrument quick disassembly and assembly tool in the confined space is small and portable, and easy for operators to use.

[0038] In one example, four feed holes B surround the outside of a central through hole C, the cross-section of which is circular at any position.

[0039] In some embodiments, please refer to Figures 1-4 The main body 1 has a chamfered part 4 cut into each corner area A along its circumference, and each chamfered part 4 corresponds to a claw 3. The claw 3 includes a first branch 31, a second branch 32 and a third branch 33 connected in sequence. The first branch 31, the second branch 32 and the third branch 33 all extend in a straight line, and the second branch 32 corresponds to the chamfered part 4.

[0040] In the embodiments of this application, it can be understood that by setting corresponding chamfered parts 4 in the four corner areas A of the main body 1, it is convenient for operators to use. The claw 3 is structurally arranged in three sections. The first section 31, the second section 32 and the third section 33 can limit the instrument by cooperating and moving inward.

[0041] In summary, compared with the prior art, this application has the following beneficial effects:

[0042] 1. In this application, the main body 1 of the structure is provided with four feeding holes B along its own length direction. The feeding holes B provide a space for the assembly parts and screwdrivers to move and operate. The threaded part in the feeding hole B can constrain the degree of freedom of movement of the assembly parts in space and allow the assembly parts to pass through in one direction. The problem of screwdriver slippage and easy misalignment of the assembly parts is solved by the cooperation of the four feeding holes B.

[0043] 2. The instrument quick assembly / disassembly tool provided in this application matches the shape of the instrument to be disassembled / assembled. The bottom of the main body 1 is formed with patterned grooves and four claws 3 to stably connect with the instrument. The four claws 3 correspond to multiple corner areas A of the main body 1. The cooperation of the four claws 3 enables the assembly parts and the instrument screw holes to be accurately positioned. This ensures that the assembly parts are reliably engaged with the instrument before operation, solving the problem of easy parts falling off. Operators can efficiently assemble and disassemble small cylindrical instruments in confined spaces.

[0044] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
