Description

Technical Field

[0001] The utility model relates to the technical field of circuit boards, and more specifically to a circuit board with a quick-release mechanism. Background Art

[0002] Circuit boards with quick-release mechanisms are usually used in equipment or systems that require frequent replacement or maintenance of circuit boards, such as industrial automation equipment, communication equipment, medical equipment, etc. This design can reduce the time and cost of repairing or replacing circuit boards and improve the reliability and efficiency of equipment.

[0003] The prior art discloses a circuit board with a quick-release mechanism, and the utility model patent application number is CN202322918361.1. The circuit board is provided with a positioning column, a support column and a limit piece. By pressing the push rod, the support column moves downward synchronously, and then the limit piece is elastically reset. By placing the board body on the bracket, the positioning column and the positioning hole clearance can be matched to achieve the initial positioning of the board body. When the connecting seat is released, the support column will elastically reset and resist the push rod, so that the limit piece will undergo elastic deformation and engage the positioning hole, thereby completing the fixation of the board body. Subsequently, the board body can be removed by pressing down the connecting seat.

[0004] However, when it is in use, the limit piece is squeezed so that it passes through the positioning hole to fix the bracket. However, as the number of uses increases, the limit piece is frequently squeezed and rubbed, which can easily lead to wear of the limit piece and a gradual decrease in its own resilience, thereby reducing or even failing the fixing effect on the bottom of the board. Utility Model Content

[0005] The purpose of the utility model is to overcome the shortcomings of the prior art, meet the actual needs, and provide a circuit board with a quick-release mechanism to solve the technical problem in the prior art that as the number of uses increases, the limiter is frequently squeezed and rubbed, which easily leads to wear of the limiter and gradual reduction of its own resilience, thereby reducing or failing its fixing effect on the bottom of the board.

[0006] To solve the above technical problems, the present utility model provides the following technical solutions: A circuit board with a quick-release mechanism, including a circuit board body, and further including a mounting base. The end wall of the mounting base is fixedly connected with symmetrically arranged brackets. Fixing holes are provided on the brackets, and bolts are arranged in the fixing holes. Four corners of the mounting base are each hinged with a rotating rod through a torsion spring. Push rods are fixedly connected to the outer walls of the rotating rods. A limiting hole penetrating through the mounting base is provided at the top of the mounting base. One end of the push rod away from the rotating rod extends to the bottom of the limiting hole. The ends of the rotating rods are each hinged with a U-shaped rod through a torsion spring. Clamping blocks are fixedly connected to the upper outer walls of the U-shaped rods. An adjusting mechanism for adjusting the angle of the push rod is arranged in the limiting hole; the mounting base is fixed in the equipment or system where the circuit board needs to be used through the bolts and the brackets. By pushing the circuit board body onto the mounting base, the circuit board body drives the adjusting mechanism to squeeze the push rod, and limits it after squeezing, so as to realize the fixing of the circuit board body by the movement of the clamping block. Similarly, when the circuit board body needs to be removed, pressing the circuit board body again can take it out, thus realizing the quick disassembly and assembly of the circuit board body. During this process, no special mechanism needs to be installed on the circuit board body, ensuring the production and use costs of the circuit board body.

[0007] The adjusting mechanism includes a limiting tube. The limiting tube is fixedly connected to the inner wall of the limiting hole. A pressing column is arranged above the limiting tube. One end of the pressing column penetrates through the limiting tube and extends to its bottom to abut against the push rod. The outer wall of the pressing column is slidably connected to the inner wall of the limiting tube at the place where it is penetrated. A plurality of uniformly arranged sliding blocks are fixedly connected to the outer wall of the pressing column. The sliding blocks are diamond-shaped. A plurality of uniformly arranged locking blocks are fixedly connected to the inner wall of the limiting tube. The bottom of the locking block is inclined. Adjacent two locking blocks cooperate with each other to form a channel for the locking block to move. A plurality of uniformly arranged guiding blocks are also fixedly connected to the inner wall of the limiting tube. The guiding blocks are inclined. One end of the pressing column extending to the bottom of the limiting tube is fixedly connected with a spring sleeved inside it. The other end of the spring is fixedly connected to the bottom of the limiting tube; through the arranged sliding blocks, locking blocks and guiding blocks, it is realized that by pressing the pressing column, the movement and fixing of the pressing column can be realized, so that the pressing column squeezes, limits and releases the push rod, making the adjustment of the push rod simple and efficient.

[0008] Preferably, a bearing plate is rotatably connected to the top of the pressing column; through the arranged bearing plate, the bottom of the circuit board body is directly attached to the bearing plate, thereby preventing wear between the bottom of the circuit board body and the pressing column, resulting in a decrease in the service life of the circuit board body.

[0009] Preferably, symmetric heat dissipation grooves are formed at the top of the bearing plate, and the heat dissipation grooves penetrate through the bearing plate, so that the heat at the bottom of the circuit board body can pass through the heat dissipation grooves and be discharged from the gap between the bearing plate and the mounting seat, thereby achieving the effect of dissipating heat from the bottom of the circuit board body.

[0010] Preferably, rubber pads are fixedly connected to the bottoms of the clamping blocks; the rubber pads provided can prevent the clamping blocks from contacting and wearing the circuit board body when the circuit board body is fixed.

[0011] Preferably, anti-slip plates are fixedly connected to the outer wall of the bearing plate; the anti-slip plates are provided to limit the circuit board body, thereby preventing its position from shifting during use.

[0012] Compared with the prior art, the beneficial effects of the present utility model are:

[0013] 1. In the present utility model, the mounting seat is fixed in a device or system that needs to use the circuit board through bolts and brackets. By pushing the circuit board body onto the mounting seat, the circuit board body drives the adjusting mechanism to squeeze the push rod, and limits it after squeezing, so as to realize the fixing of the circuit board body by moving the clamping blocks. Similarly, when the circuit board body needs to be removed, pressing the circuit board body again can take it out, thereby realizing the quick disassembly and assembly of the circuit board body. During this process, no special mechanism needs to be installed on the circuit board body, ensuring the production and use costs of the circuit board body.

[0014] 2. The present utility model also directly fits the bottom of the circuit board body with the bearing plate through the provided bearing plate, which can not only reduce the excessive stress on the local part of the circuit board body when pushing the circuit board body to move, but also prevent the bottom of the circuit board body from wearing between the pressing columns, resulting in a decrease in the service life of the circuit board body.

[0022] As Figures 1 to 5 shown, a circuit board with a quick-release mechanism according to the present utility model includes a circuit board body 1, and further includes a mounting seat 2. Symmetrically arranged brackets 3 are fixedly connected to the end wall of the mounting seat 2. Fixing holes 4 are formed in the brackets 3, and bolts 5 are arranged in the fixing holes 4. Rotating rods 6 are hinged to the four corners of the mounting seat 2 through torsion springs. Push rods 7 are fixedly connected to the outer walls of the rotating rods 6. Limiting holes 8 penetrating through the mounting seat 2 are formed in the top of the mounting seat 2. One ends of the push rods 7 away from the rotating rods 6 extend to the bottoms of the limiting holes 8. U-shaped rods 9 are hinged to the ends of the rotating rods 6 through torsion springs. Clamping blocks 10 are fixedly connected to the upper outer walls of the U-shaped rods 9. An adjusting mechanism for adjusting the angle of the push rods 7 is arranged in the limiting holes 8;

[0023] The adjusting mechanism includes a limiting tube 11 which is fixedly connected to the inner wall of the limiting hole 8. A pressing column 12 is arranged above the limiting tube 11. One end of the pressing column 12 penetrates through the limiting tube 11 and extends to its bottom to abut against the push rod 7. The outer wall of the pressing column 12 is slidably connected to the inner wall of the limiting tube 11 at the position where it is penetrated. A plurality of uniformly arranged sliding blocks 13 are fixedly connected to the outer wall of the pressing column 12. The sliding blocks 13 are diamond-shaped. A plurality of uniformly arranged locking blocks 14 are fixedly connected to the inner wall of the limiting tube 11. The bottom of the locking block 14 is inclined. Adjacent two locking blocks 14 cooperate with each other to form a channel for the movement of the locking block 14. A plurality of uniformly arranged guiding blocks 15 are also fixedly connected to the inner wall of the limiting tube 11. The guiding blocks 15 are inclined. One end of the pressing column 12 extending to the bottom of the limiting tube 11 is fixedly connected with a spring 16 sleeved inside it. The other end of the spring 16 is fixedly connected to the bottom of the limiting tube 11. The mounting base 2 is fixed in the equipment or system that needs to use the circuit board through the bolt 5 and the bracket 3. By pushing the circuit board body 1 onto the mounting base 2, through the arranged sliding blocks 13, locking blocks 14 and guiding blocks 15, it is realized that by pressing the pressing column 12 with the circuit board body 1, the movement and fixation of the pressing column 12 can be achieved, so that the pressing column 12 squeezes, limits and releases the push rod 7, making the adjustment of the push rod 7 simple and efficient, and limiting it after extrusion, so as to realize the fixation of the circuit board body 1 by moving the clamping block 10. Similarly, when the circuit board body 1 needs to be removed, pressing the circuit board body 1 again can take it out, thus realizing the quick disassembly and assembly of the circuit board body 1. During this process, no special mechanism needs to be installed on the circuit board body 1, ensuring the production and use costs of the circuit board body 1.

[0024] Further, a bearing plate 17 is rotatably connected to the top of the pressing column 12. Through the arranged bearing plate 17, the bottom of the circuit board body 1 is directly attached to the bearing plate 17, thus preventing wear between the bottom of the circuit board body 1 and the pressing column 12 and reducing the service life of the circuit board body 1.

[0025] Further, symmetrically arranged heat dissipation grooves 18 are formed in the top of the bearing plate 17, and the heat dissipation grooves 18 penetrate through the bearing plate 17. Through the arranged heat dissipation grooves 18, the heat at the bottom of the circuit board body 1 can pass through the heat dissipation grooves 18 and be discharged from the gap between the bearing plate 17 and the mounting base 2, thus achieving the effect of dissipating heat from the bottom of the circuit board body 1.

[0026] Further, rubber pads 19 are fixedly connected to the bottoms of the clamping blocks 10. By arranging the rubber pads 19, it can be prevented that when the clamping blocks 10 fix the circuit board body 1, the clamping blocks 10 and the circuit board body 1 are in contact and worn.

[0027] Furthermore, anti-slip plates 20 are symmetrically and fixedly connected to the outer wall of the bearing plate 17; by providing the anti-slip plates 20, the circuit board body 1 is limited, thereby preventing its position from shifting during use.

[0028] Working principle: This embodiment provides a circuit board with a quick-release mechanism. During use, the mounting base 2 is fixed to the device or system that requires the use of the circuit board through the bolt 5 and the bracket 3. Then, the circuit board body 1 is pressed against the bearing plate 17. When the bearing plate 17 is manually pressed, it will move and press the pressing column 12. When the pressing column 12 is pressed, it will drive the slider 13 to move in the channel formed between the locking blocks 14. After contacting the guiding block 15, it will be blocked by the guiding block 15. As a result, the slider 13 will rotate together with the pressing column 12 along the inclined outer wall of the guiding block 15. At this time, the circuit board body 1 is released and no longer pressed. The spring 16 will push the pressing column 12 to move back under its own elastic force. The movement of the pressing column 12 drives the slider 13 to move back. During the movement of the slider 13, it is blocked by the inclined part of the locking block 14, so that the pressing column 12 cannot move. It should be noted that when the pressing column 12 moves, its bottom squeezes the push rod 7, so that the push rod 7 drives the rotating rod 6 to rotate. The end of the rotating rod 6 is hinged to the U-shaped rod 9 through a torsion spring. Therefore, after the rotating rod 6 rotates and drives the U-shaped rod 9 to rotate, when the U-shaped rod 9 contacts the outer edge of the bearing plate 17 and is squeezed, the U-shaped rod 9 cannot rotate anymore. So the U-shaped rod 9 will stick to the outer edge of the bearing plate 17 under the torsion force of its own torsion spring, so that the clamping block 10 on the U-shaped rod 9 clamps the circuit board body 1, thereby realizing the quick fixation of the circuit board body 1.

[0029] Similarly, when the circuit board body 1 needs to be disassembled, the circuit board body 1 is pressed again, so that the pressing column 12 moves down again, so that the slider 13 moves down again and contacts and rotates with the guiding block 15, so that the slider 13 can return to move in the channel formed between the locking blocks 14, so that the pressing column 12 is reset, so that the pressing column 12 gradually stops squeezing the push rod 7, so that the rotating rod 6 rotates the U-shaped rod 9 to reset and twist under its own torsion force, so that the clamping block 10 no longer fixes the circuit board body 1, thereby realizing the quick disassembly of the circuit board body 1.

[0030] The embodiments disclosed in this utility model are preferred embodiments, but not limited to this. Those of ordinary skill in the art can easily understand the spirit of this utility model according to the above embodiments and make different extensions and changes. However, as long as they do not depart from the spirit of this utility model, they are within the protection scope of this utility model.
