DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0026] like Figure 1-Figure 5 As shown, a combined PCB circuit board proposed in one embodiment of the present application includes a board body 1, which is an existing PCB circuit board, and also includes:

[0027] The connecting block 2 has first abutment plates 3 vertically connected to opposite sides thereof, and ends of the two first abutment plates 3 extend in a direction away from the connecting block 2;

[0028] The plug block 4 vertically slides through the connecting block 2. The length and width of the plug block 4 are smaller than the connecting block 2. The plug block 4 penetrates the connecting block 2 from bottom to top and slides with the connecting block 2. A slider 401 is constructed on the plug block 4. A slide groove 201 for accommodating the slider 401 is constructed on the connecting block 2. Under the action of the slider 401 and the slide groove 201, the plug block 4 and the connecting block 2 will not be completely separated. The back sides of the plug block 4 are vertically connected with second abutment plates 5. The second abutment plates 5 have the same extension direction as the first abutment plates 3 on the same side, and the first abutment plates 3 and the second abutment plates 5 are far away from each other. The first abutment plates 3 and the second abutment plates 5 are respectively located at the top end of the connecting block 2 and the bottom end of the plug block 4. When the plug block 4 slides toward the connecting block 2, the second abutment plates 5 on both sides thereof move toward the first abutment plates 3, so as to abut against the plate body 1 placed therebetween.

[0029] The fixing mechanism 6 is used to fix the plug block 4 and the connecting block 2. When the second abutment plate 5 cooperates with the first abutment plate 3 to form a resistance against the plate body 1, the position of the plug block 4 and the connecting block 2 can be fixed by the fixing mechanism 6, so that the plate body 1 can be clamped and fixed by the first abutment plate 3 and the second abutment plate 5, so that the plate body 1 is not easily separated from the second abutment plate 5 and the first abutment plate 3, so that the connection of the two plate bodies 1 can be achieved. Compared with the prior art, the fixing and disassembly between the multiple plate bodies 1 do not need to be performed with the help of tools, which is relatively simple and easy to use;

[0030] The present application adopts the design of the fixing mechanism 6. When the plug block 4 slides toward the connecting block 2, the second abutment plates 5 on both sides thereof can move toward the first abutment plate 3, so as to abut the plate body 1 placed therebetween. Subsequently, the positions of the plug block 4 and the connecting block 2 can be fixed by the fixing mechanism 6, so that the plate body 1 can be clamped and fixed by the first abutment plate 3 and the second abutment plate 5, so that the plate body 1 is not easily separated from the second abutment plate 5 and the first abutment plate 3, thereby realizing the connection between the two plate bodies 1. Compared with the prior art, the fixing and disassembly of multiple plate bodies 1 do not require the aid of tools, which is relatively simple and easy to use.

[0031] like Figure 1-Figure 5 As shown, in some embodiments, the fixing mechanism 6 includes a through slot 601 that penetrates the back side of the insert block 4, and a rotating rod 602 is rotatably matched on the insert block 4, the bottom end of which penetrates the through slot 601, and the rod 602 penetrates the middle of the through slot 601, and a strip baffle 603 is connected thereto, the width of the strip baffle 603 is less than the width of the insert block 4, and the length of the strip baffle 603 is greater than the length of the through slot 601, and the strip baffle 603 can be rotated by rotating the rotating rod 602, and when the extension direction of the strip baffle 603 is parallel to the side of the insert block 4, the strip baffle 603 can be stored in the through slot 6 01, when the extension direction of the strip baffle 603 is perpendicular to the side of the plug block 4, the two ends of the strip baffle 603 can extend out of the notch of the through groove 601, and the connecting block 2 is provided with a slot 604 for accommodating the strip baffle 603, and the slot 604 is used to accommodate the two ends of the strip baffle 603, so that the movement of the plug block 4 and the connecting block 2 can be limited by the strip baffle 603 and the slot 604, and the top of the rotating rod 602 passes through the plug block 4, and a push plate 605 is connected to it, and the rotating rod 602 can be driven to rotate along its own axis by pushing the push plate 605.

[0032] like Figure 2 and Figure 3 As shown, in some embodiments, flexible blocks 7 are installed on the tops of both ends of the strip baffle 603, and the flexible blocks 7 are rubber blocks. When the strip baffle 603 enters the slot 604, the flexible blocks 7 can be deformed and abut against the inner wall of the slot 604, so that the strip baffle 603 is not easily separated from the slot 604 under the action of the flexible blocks 7.

[0033] like Figure 2-Figure 5As shown, in some embodiments, the top of the rotating rod 602 is vertically connected to the middle of the push plate 605, and the axes of the push plate 605 and the strip baffle 603 are parallel to each other, so that the push plate 605 can move synchronously with the strip baffle 603, and the width of the plug block 4 is less than the length of the push plate 605 and greater than the width of the push plate 605. When the push plate 605 is parallel to the side of the plug block 4, the strip baffle 603 is received in the through groove 601, the sliding of the plug block 4 and the connecting block 2 is not affected, and the bottom end of the push plate 605 contacts the plug block 4. When the push plate 605 is perpendicular to the side of the plug block 4, the two ends of the strip baffle 603 extend out of the through groove 601 and are inserted into the card slot 604. At this time, the two ends of the push plate 605 conflict with the top of the connecting block 2, so that the plug block 4 cannot move downward. By adopting such a design, the burden of the strip baffle 603 can be reduced, making it less likely to be damaged.

[0034] like Figure 4 and Figure 5 As shown, in some embodiments, a positioning rod 8 is constructed on the top of the second support plate 5, and positioning holes 9 are arranged around the plate body 1. There are four positioning holes 9 and they are arranged in a centrally symmetrical shape. They are used to accommodate the positioning rod 8. When the first support plate 3 and the second support plate 5 cooperate to fix the plate body 1, the positioning holes 9 can accommodate the positioning rod 8, so that the fixing effect of the plate body 1 can be improved by the positioning rod 8.

[0035] like Figure 4 and Figure 5 As shown, in some embodiments, a slot 10 is provided at the bottom of the first abutment plate 3 for accommodating the positioning rod 8. The slot 10 is used to accommodate the end of the positioning rod 8, thereby increasing the force points of the positioning rod 8 to protect it and prevent it from breaking easily.

[0036] like Figure 4 and Figure 5 As shown, in some embodiments, the insertion end of the positioning rod 8 is configured with an arc surface 11 , and the arc surface 11 is designed mainly to play a guiding role, so as to facilitate the positioning rod 8 to be inserted into the slot 10 .

[0037] like Figure 4 and Figure 5 As shown, in some embodiments, flexible pads 12 are connected on opposite sides of the first abutment plate 3 and the second abutment plate 5. The flexible pads 12 are rubber pads and are provided with holes for passing the positioning rods 8. By adopting such a design, the plate body 1 can be protected so that it is not easy to be damaged by indentations when the first abutment plate 3 and the second abutment plate 5 collide with each other.

[0038] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
