Description

Technical Field

[0001] This utility model relates to the field of circuit board technology, and in particular to a splicing circuit board that is easy to disassemble quickly. Background Technology

[0002] A circuit board, also known as a printed circuit board, is mainly composed of pads, vias, mounting holes, wires, components, connectors, fillers, and electrical boundaries. The components of a circuit board are mainly insulating substrates and conductors. In electronic devices, it plays a supporting, interconnecting, and partial circuit component role. Integrated circuits and electronic components such as resistors and capacitors cannot function as individual units. Only when they have a place on the circuit board and are connected by conductors can they perform their functions in the whole.

[0003] In existing technologies, circuit boards often require drilling screw holes and then fixing them with screws. However, screw fixing is not only inconvenient for disassembly and maintenance, but the screws used on circuit boards are also small and are very easy to lose during disassembly and assembly, thus making it impossible to fix the circuit board. Utility Model Content

[0004] The purpose of this invention is to provide a splicing circuit board that is easy to disassemble and reassemble quickly. This circuit board does not require screws for fixing, will not damage the circuit board body, and is easier to assemble and disassemble.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a splicing circuit board that is easy to disassemble quickly, comprising a circuit board body and a mounting box. The mounting box includes a box body and a box cover. The box cover is provided with a slot for embedding the circuit board body. The box body has an installation groove. The box cover and the circuit board body embedded in the slot can be inserted into the installation groove by sinking. The box body is provided with an anti-detachment structure to prevent the box cover from falling out of the installation groove. The anti-detachment structure includes a first sliding groove on both sides of the groove opening, an anti-detachment block slidably disposed in the first sliding groove, and a driving component for driving the anti-detachment block to slide into or out of the groove opening. A support base is fixedly disposed in the installation groove. A first spring is fixedly disposed on the support base. When the anti-detachment block slides into the first sliding groove, the first spring controls the box cover to move away from the groove opening and out of the outside, and the groove opening and closing point are connected to the outside.

[0006] By adopting the above technical solution, in use, the circuit board body is first embedded in the slot, so that the circuit board body and the cover are embedded into the mounting groove together, preventing the circuit board body from falling out of the slot. At the same time, the box body is provided with an anti-detachment structure to limit the cover, so that the cover can be stably embedded in the mounting groove under the action of the anti-detachment structure. When it is necessary to remove the circuit board body, simply slide the anti-detachment block on the anti-detachment structure into the first sliding groove, and then the first spring is compressed and released, pushing the cover out of the mounting groove. The entrance of the slot is connected to the outside, making it easy to remove the circuit board body from the slot. Through the above-mentioned settings, the circuit board body is fixed in the box body without drilling holes in the circuit board body or fixing it with screws, which will not damage the circuit board body and is very convenient for disassembly and assembly.

[0007] The further configuration is as follows: the cover is provided with a second sliding groove on both sides of the slot, which communicates with the mounting groove; a push block for pushing the circuit board body out of the slot is slidably disposed in the second sliding groove; the push block extends outward to provide a push handle; and the two push handles are fixedly connected to the same linkage rod.

[0008] By adopting the above technical solution, sliding grooves are set on both sides of the slot, and push blocks are slidably installed in the grooves. The purpose is to further facilitate the disassembly of the circuit board body. When the circuit board body is inserted into the slot, it is usually fully inserted into the slot to better protect the circuit board body. At this time, disassembly requires the use of tools to push it. Therefore, by setting the push blocks, the push blocks extend to the outside and are connected to push handles. The push handles are easy to operate manually, and the linkage rods are easy to control each push block in a coordinated manner. Therefore, with the above solution, after the circuit board body is inserted into the slot, when disassembling the circuit board body, it is only necessary to push the linkage rods by hand. The linkage rods control the push blocks and push handles in a coordinated manner to push the circuit board body out of the slot and remove it. The operation is more convenient and faster. By setting the linkage rods, the linkage rods play a role in connecting and transmitting power during the linkage control process. They can evenly distribute the power of the drive source to each push block, thereby ensuring the stable operation of the entire system.

[0009] The drive assembly is further configured as follows: each anti-detachment block is connected to an L-shaped connecting block, an active cavity is opened in the box body for the L-shaped connecting block to move, the active cavity has a pair of slide holes communicating with the outside, a drive column that moves toward the inside of the active cavity is slidably arranged in the slide holes, a threaded column located between the pair of slide holes and fixedly arranged on the outside of the box body, an adjustment plate that is threadedly connected to the threaded column and reciprocates toward the drive column, and a handle arranged on the adjustment plate. The pair of drive columns are both located below the orthographic projection of the end face of the adjustment plate, and the handle is located above the orthographic projection of the end face of the adjustment plate. The drive column includes a first linkage structure that forms a linkage with the L-shaped connecting block at one end and a second linkage structure that forms a linkage with the adjustment plate at the other end.

[0010] By adopting the above technical solution, and through the setting of the drive component, the drive component enables the L-shaped connecting block to drive the anti-detachment block to move, which facilitates the insertion of the cover into the mounting slot for fixation or the removal of the circuit board body from the mounting slot. Therefore, through the above solution, by manually turning the handle, the handle drive column pushes and drives the two L-shaped connecting blocks to move. The L-shaped connecting block will drive the movement of each anti-detachment block, and the anti-detachment block will move out of the first sliding groove. Its operation is simple and quick.

[0011] The first linkage structure includes an inclined surface formed between the L-shaped connecting block and the drive column. One end of the drive column extends into the movable cavity and abuts against the inclined surface. When the drive column slides from the top to the bottom of the inclined surface, the two L-shaped connecting blocks move in opposite directions. A second spring is connected between the two L-shaped connecting blocks to make them move towards each other.

[0012] By adopting the above technical solution, and through the setting of the second spring, when the second spring receives the restoring force, the second spring will drive the two L-shaped connecting blocks to move towards each other. The anti-detachment block connected to the L-shaped connecting block will move away from the first sliding groove. Through the cooperation of the inclined plane and the drive column, the drive column abuts against the inclined plane. When the drive column moves, the drive column squeezes the inclined plane, causing the two L-shaped connecting blocks to move in opposite directions. This realizes that the L-shaped connecting block drives the anti-detachment block to slide into the first sliding groove. Through the setting of the first linkage structure, the rapid movement of the L-shaped connecting block and the anti-detachment block is realized. This design greatly simplifies the disassembly and installation process of the circuit board.

[0013] Further configuration: the two inclined planes are shaped like an inverted V.

[0014] By adopting the above technical solution, the inclined slope with an inverted V-shape design helps to ensure that the push block can smoothly drive the two locking blocks to move during the sliding process.

[0015] The second linkage structure is further configured as follows: an annular linkage groove is formed on the end face of the adjustment disk facing the drive column and surrounds the center of the adjustment disk. One end of each drive column extends into the linkage groove. The linkage groove and the end of the drive column extending into the linkage groove are slidably engaged and form a linkage along the axial direction of the threaded column.

[0016] By adopting the above technical solution and setting the linkage groove, each drive column is stably controlled by the adjustment plate, which plays the role of connecting and transmitting power. It can evenly distribute the power of the drive source to each drive column, thereby ensuring the stable operation of the entire system. Attached Figure Description
