The card slot 112 cooperates, and when the pin 22 is combined with the card slot 112, the handle 21 can be used to match the single The board is lifted. With the technical solution of this embodiment, the fastening component 1 takes up less space, and the handle assembly 2 is more convenient to disassemble and assemble.

Embodiment 2

Figure 2 shows the overall structure of the disassembly device. The components of the assembly and disassembly device are as follows: As shown in Fig. 3, the fastening component 1 can be fixed on the single board. In this embodiment, the stud 11 and the nut 12 are fixed through the through hole 5 of the single board.

As shown in Fig. 4 and Fig. 5, the handle assembly 2, the handle end is a handle 21, and the structure is various; as shown in Fig. 4, the other end of the handle is cylindrical, the central opening blind hole 23; the blind hole 23 has a spacer 25 The sidewalls of the blind holes 23 are symmetrically designed with two pin holes 24; the pin holes 24 are provided with pins 22 therein. Here, the structure of the handle assembly 2 can be used in other configurations when it is ensured to be engaged with the stud 11, as shown in Fig. 5, the spacer 25 is omitted, and the pin 22 and the handle 21 are used. Integrated molding.

As shown in Fig. 6, the nut 12 can be designed to have a nut shoulder 121. With the limit of the shoulder 121, the screw 11 and the nut 12 can be screwed to ensure the fastening of the two to the single-plate via 5. The shoulder 121 structure is coupled to the mating hole of the veneer 5 by welding; the threaded hole in the middle is a through hole, and the thread size is matched with the thread on the stud 11. The small end of the nut 12 is matched with the single-plate via 5, and is soldered and fixed to the single-plate via 5 through the mating surface. The nut 12 can also be used with national standard or other similar structural forms.

As shown in Fig. 7, the stud 11 is composed of two segments, and a thread is arranged on a segment of the cylinder to achieve a fastening connection with the nut 12. The other columnar structure is provided with a card slot 112. The structure of the slot 112 is an L+I. The structure is configured to engage and lock with the pin 22, and the stud shoulder 122 is provided for limiting. The screw 11 and the nut 12 are threaded to ensure the fastening of the two to the single-plate via 5 .

As shown in Fig. 8, the pin 22 has a cylindrical structure, and the specific structure is various. In the disassembly and assembly action, it is used together with the slot 112 of the stud 11 to jointly realize the connection between the handle assembly 1 and the fastening assembly 2; the pin 22 and the pin hole 24 of the handle 1 achieve an interference fit, the length dimension The depth design of the structure of the L+I type card slot 112 of the stud 11 is required, as shown in FIG. 4; in addition, the pin 22 and the handle 1 can also be integrally formed and combined into one piece, such as The handle structure shown in Figure 5.

The pin holes 24 can be mated with the pins 22, and the pin holes 24 are sized to ensure that the pins 22 are not loose. As shown in FIG. 9, the spacer 25 is made of an elastic material, and cooperates with the blind hole 23 of the handle 1, and can be glued. The way to fix it. The spacer 25 generates a certain force by the deformation of the handle assembly 2 during the cooperation with the fastening assembly 1 for locking or unlocking between the handle assembly 2 and the fastening assembly 1 to make the cooperation more reliable. . The diameter of the spacer 25 in the diameter direction of the handle 1 blind hole 23 is designed to be a clearance fit. In the thickness direction, it is considered to have a compression ratio of 20% to 50% when locked, and is adjusted according to the characteristics of the material. In order to ensure that the compressive force of the spacer 25 is not too large, a groove structure as shown in the figure can be designed, and the specific structure of the groove is various. Instead of the spacer 25, a metal reed or the like can also be used. At the same time, the spacer 25 can be omitted where the requirements are not high.

As shown in Fig. 10, the diameter dimension of the blind hole 23 is matched with the shape of the stud 11 columnar structure, and the depth direction dimension is matched with the length of the spacer 25 and the stud 11 columnar structure.

As a whole, as shown in Fig. 2, the spacer 25, the pin 22 and the handle 1 constitute a handle assembly; the stud 11 and the nut 12 constitute a fastening component, which is generally fixed inside the device, and needs to be used only when disassembling and assembling. The handle assembly 2 can be matched with the stud 11 of the fastening component 1, that is, the pin 22 slides in through the L-shaped slot 112 of the stud 11 and rotates the handle 1 to complete the engagement of the L-shaped slot 112 and enter the L-shaped card. The groove 112 is engaged, and the handle assembly 2 and the fastening assembly 1 are locked by the action of the spacer 25. Then you can perform the disassembly and assembly of the board. After the disassembly and assembly action, the handle 1 is gently pressed to release the pin 22 from the I-shaped slot 112, and the handle 1 is rotated to unlock the two components and enter the L-shaped slot 112, and then the handle assembly 2 is disengaged from the fastening assembly 1. , the entire disassembly operation is over.

As described above, the present embodiment can disassemble the board in a small space, and effectively solve the problem that at least the small space disassembly and assembly of the prior art is difficult to operate or the operation requires too much space. one.

Embodiment 3

This embodiment is a single board that is easy to disassemble.

As shown in Figure 11, there are several vias 5 on the board and the fastening components 1 on the vias.

As shown in Figure 12, the board is opened. A single via hole 5 is formed on the board, and the pad form of the via hole is not specially required to meet the requirements of the solder. If a non-welded nut structure is used, the via 5 of the board may be without a pad.

After the nut 12 is welded to the single-plate via 5, the stud 11 passes through the single-plate via 5 and cooperates with the nut 12 to form a single-board assembly. Then complete the board disassembly and assembly with the handle assembly. If the nut 12 is not welded It is fixed, and it can be directly connected with the thread of the stud 11 without being welded to the single-plate via 5 .
