Description

Technical Field

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

[0002] A server is a specific IT device that provides computing power and runs software applications in a network environment. It provides computing or application services for other client machines (such as terminal devices like personal computers, smartphones, ATM machines, etc.) in the network.

[0003] Currently, when installing the server motherboard in the server, hand-tightening screws are usually used to achieve quick disassembly and assembly. However, since the materials of hand-tightening screws are usually plastics that are not resistant to high temperatures, and the server motherboard often needs to be repaired in a high-temperature environment when it is returned to the factory for repair, it is necessary to disassemble the hand-tightening screws before repair. However, the inside of the hand-tightening screw usually has an anti-disassembly structure. Once it is fixed on the server motherboard, it cannot be disassembled by conventional tools such as an electric screwdriver or a manual screwdriver. It is necessary to damage the outer shell of the hand-tightening screw to remove the hand-tightening screw. During the disassembly process, since the hand-tightening screw is assembled in the patch stud of the server motherboard, the destructive disassembly process is likely to damage the copper foil of the patch stud, resulting in the scrapping of the server motherboard and causing unnecessary losses.

[0023] Figure 1 and Figure 2 are schematic diagrams of the disassembly device according to the embodiments of the present utility model. Refer to Figure 1 and Figure 4 The disassembly device includes a fixed seat 1, a rotating disassembly rod 2 and a clamping arm 3. The disassembly device is used to disassemble a hand-tightened screw 8, and the hand-tightened screw 8 includes a plastic shell 801 and a screw body 802, and the screw body 802 is fixed in the plastic shell 801. Further, the rotating disassembly rod 2 is rotatably installed on the fixed seat 1. One end of the rotating disassembly rod 2 is provided with a handle 201, and the other end is provided with a pressing head 202 that rotates synchronously with the handle 201. After the pressing head 202 rotates clockwise through the handle 201, it extends into the plastic shell 801 and presses down on the screw body 802. Then, the clamping arm 3 is connected to the fixed seat 1, and the clamping arm 3 is provided with a clamping groove 301 for clamping and fixing the plastic shell 801 so that the screw body 802 is disposed opposite to the pressing head 202 of the rotating disassembly rod 2. Further, continue to refer to Figure 4, when it is necessary to disassemble the manual screw 8 on the main board, first, the plastic shell 801 is fixed through the clamping groove 301 on the clamping arm 3, and then the rotating disassembly rod 2 is rotated until its extrusion head 202 presses downward on the screw body 802. Then, the rotating disassembly rod 2 is continuously rotated until the screw body 802 is separated from the plastic shell 801. Finally, the rotating disassembly rod 2 is rotated in the reverse direction to drive the entire manual screw 8 away from the main board, thus completing the disassembly of the manual screw 8. Through the above disassembly method, damage to the main board can be avoided during the disassembly of the manual screw 8, and the overall operation method is simple, fast, and efficient.

[0024] Next, in order to enable the clamping arm 3 to adapt to manual screws 8 of different sizes, so that the disassembly device can be applied to the disassembly of various manual screws 8. Refer to Figure 2 The clamping groove 301 on the clamping arm 3 includes symmetrically arranged stepped wall bodies 4. The wall body 4 is provided with a first step 401 and a second step 402 connected in sequence. A first clamping end 404 is formed by the cooperation between the two first steps 401, and a second clamping end 405 is formed by the cooperation between the two second steps 402. The two first steps 401 are symmetrically arranged, and the two second steps 402 are also symmetrically arranged. Moreover, the width of the second clamping end 405 is larger than that of the first clamping end 404, that is, the size of the manual screw 8 that the second clamping end 405 can clamp is larger than the size of the manual screw 8 that the first clamping end 404 can clamp. At the same time, the stepped setting form is very convenient to use. In addition, in order to enable the clamping arm 3 to adapt to more manual screws 8 of different sizes, third steps 403 are provided on both wall bodies 4 of the clamping groove 301. The third step 403 is connected to the second step 402. A third clamping end 406 is formed by the symmetrical arrangement between the two third steps 403. The width of the third clamping end 406 is larger than that of the second clamping end 405, that is, the size of the manual screw 8 that the third clamping end 406 can clamp is larger than the sizes of the manual screws 8 that the second clamping end 405 and the first clamping end 404 can clamp, so as to further increase the size range of the manual screws 8 that the clamping arm 3 can clamp. Secondly, in order to enhance the structural strength of the overall wall body 4 of the clamping arm 3, extend its service life, and simplify the production process of the clamping arm 3, the third step 403, the second step 402, and the first step 401 are integrally formed.

[0025] Then, in order to facilitate the adjustment of the clamping arm 3, refer to Figure 1 and Figure 3The clamping arm 3 is provided with an adjusting plate 5 parallel to the fixed seat 1. The adjusting plate 5 is movably installed on the fixed seat 1 to adjust the position of the clamping arm 3 through the adjusting plate 5. Moreover, a plurality of adjusting holes 501 are provided on the adjusting plate 5, and a first assembly hole 101 is provided on the fixed seat 1. When it is necessary to install the adjusting plate 5 on the fixed seat 1, after the first assembly hole 101 coincides with one of the adjusting holes 501, an assembly bolt 6 is assembled to fix the clamping arm 3 with the adjusting plate 5 on the fixed seat 1. Through the cooperation among the assembly bolt 6, the first assembly hole 101 and the adjusting hole 501, the installation and fixation of the adjusting plate 5 on the fixed seat 1 are realized. Moreover, since there are a plurality of adjusting holes 501, a suitable adjusting hole 501 can be selected to install the adjusting plate 5 on the fixed seat 1 when adjusting the position of the clamping arm 3, which is convenient for the installation and fixation of the adjusting plate 5 on the fixed seat 1 and can cooperate with the use of different clamping ends on the clamping arm 3 at the same time. Among them, the adjusting hole 501 and the first assembly hole 101 can be round holes or through holes of other shapes. Secondly, in order to realize the sliding of the adjusting plate 5 in the fixed seat 1, limiting blocks 102 are symmetrically arranged at the bottom of the fixed seat 1, and a slideway is formed between the two limiting blocks 102. In this way, when the adjusting plate 5 moves, it will be restricted by the two limiting blocks 102 in the slideway, thereby improving the stability of the adjusting plate 5 when moving. The limiting blocks 102 and the fixed seat 1 can be integrally formed to improve the structural strength between the two.

[0026] Further, referring to Figure 1 , a second assembly hole 103 is provided on the fixed seat 1, and thread structures are provided both in the second assembly hole 103 and on the rotating disassembly rod 2, so that the rotating disassembly rod 2 is rotatably installed on the fixed seat 1. That is to say, the inner thread structure can be in the second assembly hole 103 and the outer thread structure is on the rotating disassembly rod 2. The outer thread structure and the inner thread structure together form the above-mentioned thread structure, and finally the rotating disassembly rod 2 is installed on the fixed seat 1 by rotation.

[0027] Finally, referring to Figure 4 , the disassembly process of the hand-tightening screw 8 by the disassembly device in this embodiment is as follows: First, a suitable clamping groove 301 needs to be selected on the clamping arm 3 to clamp and fix the plastic shell 801 on the hand-tightening screw 8. Then, the rotating disassembly rod 2 is rotated through the handle 201. After the pressing head 202 on the rotating disassembly rod 2 rotates clockwise, it extends into the plastic shell 801 and presses down the screw body 802. Then, the rotating disassembly rod 2 is continuously rotated until the screw body 802 is separated from the plastic shell 801. Finally, the rotating disassembly rod 2 is rotated in the reverse direction to drive the entire hand-tightening screw 8 away from the main board, thereby completing the disassembly of the hand-tightening screw 8.
