[0001] This utility model relates to the field of circuit board processing technology, specifically to a quick loading and unloading auxiliary circuit board fixture. Background Technology

[0002] Circuit boards are the core carriers of electronic components. They form conductive paths by etching copper layers. Their processing requires multiple steps such as drilling, soldering, and testing. Fixtures are special tools for fixing and protecting circuit boards, and they must ensure that they are accurately positioned and without displacement during the processing.

[0003] Traditional fixtures typically employ a combination of a lower support plate and an upper pressure plate, with both generally secured by bolts. However, bolting requires the use of additional tools to tighten multiple bolts individually, and disassembly similarly necessitates gradual loosening, resulting in a lengthy process. Furthermore, operational errors during this process can lead to stripped or lost bolts, causing unnecessary losses. Therefore, those skilled in the art provide a quick-release auxiliary circuit board fixture to address the problems mentioned in the background art. Summary of the Invention

The fixed shell is fixedly connected to the upper end face of the lower support plate, and the connecting block is fixedly connected to the lower end face of the upper pressure plate. A snap-fit ​​block extends through both sides of the fixed shell and slides within the fixed shell. A placement groove is provided at the lower end of the connecting block, matching the fixed shell. Slots are provided on both inner walls of the placement groove. Two snap-fit ​​blocks and two slots correspond one-to-one, with each pair of snap-fit ​​blocks snapping into a slot. A rotating disk is rotatably connected to the upper part of the inner wall of the fixed shell. Two first connecting rods are hinged to one end face of the rotating disk. A second connecting rod is hinged to the end of each of the two first connecting rods away from the rotating disk. The ends of the two second connecting rods away from the rotating disk are respectively hinged to one side of two snap-fit ​​blocks. A rotating block is rotatably fitted onto the upper part of one side of the fixed shell, and the rotating block is coaxially connected to the rotating disk.

[0007] As a preferred embodiment of the above technical solution, the limiting component includes a fixed cylinder and a limiting groove. The fixed cylinder is fixedly connected to the upper end face of the lower support plate. Multiple limiting grooves are provided, and the multiple limiting grooves are evenly arranged around the side wall of the rotating block. A lifting block is slidably connected inside the fixed cylinder. A spring is fixedly connected between the lower end of the lifting block and the bottom wall of the fixed cylinder. A wedge block is fixedly connected to the upper end of the lifting block. The wedge block is engaged in the limiting groove. A lifting port is opened on the inner wall of the fixed cylinder on the side away from the fixed shell. The lifting port extends to the outside and communicates with the outside. A toggle block is slidably connected inside the lifting port. One end of the toggle block is fixedly connected to the side of the lifting block away from the fixed shell.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] Please see Figures 1-5 This utility model provides a technical solution: a quick-loading and unloading auxiliary circuit board fixture, including a lower receiving plate 1, a protective plate 2, and an upper pressure plate 3. There are two protective plates 2, and both the two protective plates 2 and the upper pressure plate 3 are located above the lower receiving plate 1 and between the lower receiving plate 1 and the upper pressure plate 3. The four sides of the upper surface of the lower receiving plate 1 are equipped with snap-fit ​​components 4 for fixing the upper pressure plate 3, and the four sides of the upper surface of the lower receiving plate 1 are equipped with limiting components 5 for fixing the snap-fit ​​components 4. The snap-fit ​​components 4 and the limiting components 5 correspond one-to-one. A positioning component 6 is installed below the upper pressure plate 3.

[0022] Furthermore, during assembly, the protective plate 2 is placed on top of the lower support plate 1, and then the upper pressure plate 3 is placed on top of the lower support plate 1 using the positioning component 6. The snap-fit ​​component 4 is then operated to limit and fix the upper pressure plate 3, thus achieving rapid fixation of the upper pressure plate 3. After the snap-fit ​​component 4 limits the upper pressure plate 3, the limiting component 5 can simultaneously limit the snap-fit ​​component 4, preventing accidental release of the limiting component 4 and thus ensuring instability of the upper pressure plate 3. This ensures a stable fit between the upper pressure plate 3 and the lower support plate 1, guaranteeing processing accuracy. When disassembling the upper pressure plate 3, the limiting component 5 is first operated to release the limiting component 4, and then the snap-fit ​​component 4 is operated in reverse to release the fixation of the upper pressure plate 3. This facilitates the assembly and disassembly of the upper pressure plate 3 and the lower support plate 1, simplifying the operation process and improving processing efficiency.

[0023] As one implementation method in this embodiment, please refer to Figures 2-3 As shown, the snap-fit ​​assembly 4 includes a fixed housing 401 and a connecting block 402. The fixed housing 401 is fixedly connected to the upper end face of the lower receiving plate 1, and the connecting block 402 is fixedly connected to the lower end face of the upper pressure plate 3. A snap-fit ​​block 403 extends through both sides of the fixed housing 401, and the snap-fit ​​block 403 is slidably disposed within the fixed housing 401. A placement groove 404 is provided at the lower end of the connecting block 402, and the placement groove 404 matches the fixed housing 401. Slots 405 are provided on both inner walls of the placement groove 404. Two snap-fit ​​blocks 403 correspond one-to-one with two slots 405. Each pair of snap-fit ​​blocks... Block 403 is snapped into slot 405. A rotating disk 406 is rotatably connected to the upper part of the inner wall of the fixed shell 401. Two first connecting rods 407 are hinged to one end face of the rotating disk 406. A second connecting rod 408 is hinged to the end of each of the two first connecting rods 407 away from the rotating disk 406. The ends of the two second connecting rods 408 away from the rotating disk 406 are respectively hinged to one side of the two snapping blocks 403. A rotating block 409 is rotatably sleeved on the upper part of one side of the fixed shell 401. The rotating block 409 is coaxially connected to the rotating disk 406.

[0024] Furthermore, the upper pressure plate 3 is placed above the lower support plate 1. Then, the rotating block 409 is rotated, and the rotating disk 406 inside the fixed shell 401 rotates. This allows the first connecting rod 407 and the second connecting rod 408 to unfold, causing the locking block 403 to slide out a certain distance from the fixed shell 401. The locking block 403 then automatically slides into the locking slot 405, where it engages with the slot 405 to quickly fix the upper pressure plate 3. When the upper pressure plate 3 needs to be removed, the rotating block 409 is rotated in the opposite direction to remove the locking block 403 from the slot 405, allowing the upper pressure plate 3 to be removed. This facilitates the assembly and disassembly of the upper pressure plate 3 and the lower support plate 1, simplifying the operation process and improving processing efficiency.

[0025] As one implementation method in this embodiment, please refer to Figure 1 and Figure 4 As shown, the limiting component 5 includes a fixed cylinder 501 and a limiting groove 502. The fixed cylinder 501 is fixedly connected to the upper end face of the lower support plate 1. Multiple limiting grooves 502 are provided, and the multiple limiting grooves 502 are evenly arranged around the side wall of the rotating block 409. A lifting block 503 is slidably connected inside the fixed cylinder 501. A spring 504 is fixedly connected between the lower end of the lifting block 503 and the inner bottom wall of the fixed cylinder 501. A wedge block 505 is fixedly connected to the upper end of the lifting block 503. The wedge block 505 is engaged in the limiting groove 502. A lifting port 506 is opened on the inner wall of the fixed cylinder 501 away from the fixed shell 401. The lifting port 506 extends to the outside and communicates with the outside. A toggle block 507 is slidably connected inside the lifting port 506. One end of the toggle block 507 is fixedly connected to the side of the lifting block 503 away from the fixed shell 401.

[0026] Furthermore, when the rotating block 409 is operated to unfold the first connecting rod 407 and the second connecting rod 408, the inner wall of the limiting groove 502 will contact the inclined surface of the wedge block 505. The inclined surface of the wedge block 505 is subjected to a pushing force, which is then decomposed by the inclined surface of the wedge block 505, thereby causing the lifting block 503 to be subjected to a downward pushing force. The spring 504 contracts. As the rotating block 409 is continuously rotated, the wedge block 505 can continuously move in and out of the limiting groove 502. When the first connecting rod 407 and the second connecting rod 408 are fully unfolded and the locking block 403 slides into the locking groove 405, the operation of the rotating block 409 is stopped, and the wedge block 505 is located in the limiting groove 502. Within 2, the wedge block 505, facing the inclined surface, can limit the rotation block 409, preventing it from rotating in the opposite direction. The limiting rod 10 is located at the lower end of the first connecting rod 407, thus preventing the rotation block 409 from rotating. The limiting rod 10, the limiting groove 502, and the wedge block 505 cooperate to limit and fix the rotation block 409. When it is necessary to remove the upper pressure plate 3, the user moves the actuating block 507 downward, causing the wedge block 505 to move out of the limiting groove 502. Then, the rotation block 409 is rotated in the opposite direction, causing the first connecting rod 407 and the second connecting rod 408 to retract, thereby allowing the locking block 403 to move out of the locking groove 405.

[0027] As one implementation method in this embodiment, please refer to Figure 5 As shown, the positioning component 6 includes positioning rods 601 and positioning holes 602. There are four positioning rods 601 and four positioning holes 602. The four positioning rods 601 are fixedly connected to the four corners of the lower end face of the upper pressure plate 3, and the four positioning holes 602 are respectively opened at the four corners of the upper end of the lower support plate 1. The positioning rods 601 and the positioning holes 602 are matched.

[0028] Furthermore, during assembly, the protective plate 2 is placed on the upper end of the lower support plate 1. Then, by using the positioning rod 601 in conjunction with the positioning hole 602, the upper pressure plate 3 can be aligned with the lower support plate 1. The upper pressure plate 3 is then placed above the lower support plate 1. At the same time, the positioning rod 601 in conjunction with the positioning hole 602 limits the movement between the lower support plate 1 and the upper pressure plate 3, making the relationship between the upper pressure plate 3 and the lower support plate 1 more stable.

[0029] As one implementation method in this embodiment, please refer to Figure 5 As shown, both protective plates 2 have a protective pad 7 at their upper ends. The protective pad 7 is made of soft rubber. Both sides of the lower end of the two protective plates 2 are fixedly connected with multiple insert rods 8. Both sides of the upper end of the lower support plate 1 have multiple slots 9. The multiple insert rods 8 correspond one-to-one with the multiple slots 9.

[0030] Furthermore, when placing the protective plate 2, the insert rod 8 and slot 9 are used to place the protective plate 2 at the designated position on the lower receiving plate 1. At the same time, the insert rod 8 and slot 9 can stably place the protective plate 2 on the lower receiving plate 1. After placing the protective plate 2 on the lower receiving plate 1, the circuit board to be processed is placed on the protective plate 2, and then the upper pressure plate 3 is placed. The protective plate 2 can protect the bottom of the circuit board and prevent the circuit board from being directly exposed to pressure and contacting the lower receiving plate 1 during processing, thereby protecting the circuit board. At the same time, the protective pad 7 further improves the protective effect.

[0031] As one implementation method in this embodiment, please refer to Figures 2-3 As shown, a limiting rod 10 is fixedly connected to one side of the inner wall of the fixed shell 401, and the limiting rod 10 corresponds to one of the first connecting rods 407.

[0032] Furthermore, the limiting rod 10 limits the first connecting rod 407. When the first connecting rod 407 and the second connecting rod 408 are unfolded, the locking block 403 moves completely into the locking slot 405. The lower end of the first connecting rod 407 can contact the upper end of the limiting rod 10, thereby limiting the first connecting rod 407. This can prevent the user from excessively rotating the rotating block 409, which could cause jamming between the first connecting rod 407, the second connecting rod 408, and the locking block 403.

[0033] Working principle: During assembly, the protective plate 2 is placed on the upper end of the lower support plate 1. Then, by using the positioning rod 601 in conjunction with the positioning hole 602, the upper pressure plate 3 is aligned with the lower support plate 1. The upper pressure plate 3 is then placed above the lower support plate 1. Rotating the rotating block 409 causes the rotating disk 406 inside the fixed housing 401 to rotate, which in turn unfolds the first connecting rod 407 and the second connecting rod 408, allowing the locking block 403 to slide out a certain distance from the fixed housing 401. The locking block 403 then automatically slides into the locking slot 40. Within 5, the locking block 403 engages with the locking groove 405 to quickly fix the upper pressure plate 3. When the rotating block 409 is operated to unfold the first connecting rod 407 and the second connecting rod 408, the inner wall of the limiting groove 502 contacts the inclined surface of the wedge block 505. The inclined surface of the wedge block 505 is subjected to a pushing force, which is then decomposed by the inclined surface of the wedge block 505, resulting in a downward pushing force on the lifting block 503. The spring 504 contracts, and with continuous rotation of the rotating block 409, the wedge block 505 can be continuously... The rotating block 409 moves in and out of the limiting groove 502. When the first connecting rod 407 and the second connecting rod 408 are fully extended, the locking block 403 slides into the locking groove 405, stopping the operation of the rotating block 409. The wedge block 505 is located in the limiting groove 502. The side of the wedge block 505 opposite to the inclined surface can limit the rotating block 409, preventing the rotating block 409 from rotating in the opposite direction. The limiting rod 10 is located at the lower end of the first connecting rod 407, thereby preventing the rotating block 409 from rotating. The limiting rod 10, the limiting groove 502, and the wedge block 505 are all in operation. 5. By working together, the rotating block 409 can be limited and fixed. When it is necessary to remove the upper pressure plate 3, the user moves the toggle block 507 downward, so that the wedge block 505 moves out of the limiting groove 502. Then, the rotating block 409 is rotated in the opposite direction, so that the first connecting rod 407 and the second connecting rod 408 retract, so that the locking block 403 moves out of the locking groove 405. At this time, the upper pressure plate 3 can be removed, which facilitates the assembly and disassembly of the upper pressure plate 3 and the lower support plate 1 without the need for additional tools, simplifying the operation process and improving processing efficiency.

[0034] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
