Description
Technical Field
[0001] The utility model relates to the field of plug-in board racks, in particular to a circuit board plug-in board rack. Background Art
[0002] Circuit boards, also known as printed circuit boards, are important electronic components. They are the support bodies of electronic components and the carriers for the electrical connections between electronic components. However, when transporting multiple sets of circuit boards, due to their shape and structure, they cannot be directly stacked and transported. Usually, a board rack is used to provide a fixed position for the circuit boards, making it easier to transport multiple sets of circuit boards.
[0003] Most existing circuit board racks have a simple structure, consisting of a flat plate with multiple slots on the top. Each slot is spaced apart to facilitate the placement of circuit boards. However, after the circuit boards are placed, most of them are directly exposed to the outside and cannot be clamped, fixed, or protected. When a large number of circuit boards are subsequently transported, not only are they unable to be dustproof and waterproof, but once they encounter bumpy roads, the circuit boards are easily tilted or detached from the slots. When encountering a strong electromagnetic field environment, the circuit boards will also be damaged, causing their performance to degrade, thereby affecting the use of the circuit boards.
[0004] Therefore, it is necessary to invent a circuit board inserting plate rack. Utility Model Content
[0005] The purpose of this utility model is to solve the problems raised in the above background technology.
[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a circuit board plug-in board rack, comprising a protective cover and a plug-in board, the plug-in board being movably mounted at the bottom end of the inner cavity of the protective cover, slots being spaced apart on the upper surface of the plug-in board, guide grooves being symmetrically provided on both sides of the front of the protective cover, a fixed groove being provided at the lower end of the front of the protective cover, a unwinding assembly being provided at the upper end of the front of the protective cover, a roller shutter being installed inside the unwinding assembly, a counterweight magnet being installed at the lower end of the roller shutter, and the counterweight magnet being aligned with the fixed groove.
[0007] Based on the above features: when multiple circuit boards need to be fixed, the plug-in board can be pulled out from the inside of the protective cover, and then multiple circuit boards can be inserted into the slots at intervals. After the circuit boards are inserted, the plug-in board is pushed into the protective cover, and then the unwinding assembly is rotated. At this time, the roller shutter will be released downward, and the two sides of the roller shutter are limited inside the guide groove, and the lower end is weighted by the counterweight magnet to keep the roller shutter flat and move downward. Finally, the counterweight magnet will fall to the inside of the fixed groove to limit it, so that the roller shutter can protect the front of the protective cover to prevent the circuit boards from being damaged during transportation.
[0008] Preferably, a through slot is provided at the upper end of the front face of the protective cover, the through slot is aligned with the fixing slot, and anti-slip slots are symmetrically provided on the inner wall of the lower end of the protective cover.
[0009] Based on the above features: the rolling shutter can pass through the upper end of the protective cover through the through slot, which is convenient for the lifting and lowering movement of the rolling shutter, and the anti-slip slot provided can guide and limit the insertion plate.
[0010] Preferably, anti-slip sliders are symmetrically installed on both sides of one end of the inserting plate away from the fixing groove.
[0011] Based on the above features: the plug board is slidably connected to the anti-slip groove via the anti-slip slider, so as to prevent the plug board from being separated from the protective cover when being pulled out downward.
[0012] Preferably, grooves are symmetrically provided on the inner walls on both sides of the slot, a fixing frame is provided inside the groove, a buffer spring is installed between the fixing frame and the groove, and an auxiliary roller is provided on one side of the inner cavity of the fixing frame.
[0013] Based on the above features: when the circuit board is inserted into the slot, the fixing frame will open to both sides, at which time the buffer spring will be squeezed and deformed, and the auxiliary rollers will fit on both sides of the circuit board to clamp and limit it. Since the auxiliary rollers are made of rubber material and are rotatably connected to the fixing frame, rolling friction is formed between the auxiliary rollers and the circuit board, which not only improves the clamping and fixing effect, but also prevents damage to the circuit board surface.
[0014] Preferably, a magnetic plate is installed at the bottom end of the inner cavity of the fixing groove.
[0015] Based on the above features: when the counterweight magnet drops into the fixing slot, the magnetic plate can adsorb and fix the counterweight magnet, and try to prevent the counterweight magnet from escaping from the fixing slot on its own.
[0016] Preferably, the unwinding assembly includes a shell and support plates symmetrically installed at both ends of the shell, a roller is installed in the middle of the shell, a rotating shaft is provided at both ends of the roller, a handle is installed at one end of the rotating shaft, and the handle is located on one side of the outer end of the shell.
[0017] Based on the above features: personnel can drive the shaft and roller to rotate through the handle. When the rolling curtain is not needed, the roller can be reversed so that the rolling curtain is wrapped around the outside of the roller. Preferably, the rolling curtain is made of electromagnetic shielding film. At this time, the rolling curtain will be stored inside the shell. When it is needed, the roller can be rotated forward to release the rolling curtain, and the rolling curtain will drop through the through slot.
[0018] Based on the above characteristics: when the circuit board is inside the protective cover, the roller shutter made of electromagnetic shielding film can provide protection on the front of the protective cover, improve the electromagnetic shielding effect, and try to avoid damage to the circuit board when encountering a strong electromagnetic field environment.
[0019] The beneficial effects of the utility model are:
[0020] 1. When multiple circuit boards need to be fixed, the plug-in board can be pulled out from the inside of the protective cover, and then multiple circuit boards can be inserted into the slots at intervals. When the circuit boards are inserted, the fixing frame will open to both sides. At this time, the buffer spring will be squeezed and deformed, and the auxiliary rollers will fit on both sides of the circuit board for clamping and limiting. After the circuit boards are inserted, the plug-in board is pushed into the protective cover so that the protective cover can protect the protective cover, which can not only prevent dust and water, but also prevent the circuit boards from falling off the protective cover by themselves.
[0021] 2. After the plug-in board and circuit board are pushed into the protective cover, the handle can be used to drive the shaft and roller to rotate forward. At this time, the roller curtain will be released downward through the slot. Since the roller curtain is made of electromagnetic shielding film, it can protect the front of the protective cover, improve the electromagnetic shielding effect, and minimize damage to the circuit board when encountering a strong electromagnetic field environment.
[0022] 3. The rolling shutter can pass through the upper end of the protective cover through the through slot, and the two sides of the rolling shutter are limited inside the guide slot, while the lower end is weighted by the counterweight magnet to keep the rolling shutter moving downward smoothly. When the counterweight magnet at the lower end of the rolling shutter falls into the fixed slot, the counterweight magnet can be adsorbed and fixed by the magnetic plate, trying to avoid the counterweight magnet from separating from the fixed slot on its own.

[0029] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.
[0030] Refer to the attached Figure 1-5 The utility model provides a circuit board plug-in board rack, including a protective cover 1 and a plug-in board 2. The plug-in board 2 is movably installed at the bottom end of the inner cavity of the protective cover 1. Slots 3 are spaced apart on the upper end surface of the plug-in board 2. Guide grooves 4 are symmetrically opened on both sides of the front of the protective cover 1. A fixed groove 5 is provided at the lower end of the front of the protective cover 1. A unwinding component 6 is provided at the upper end of the front of the protective cover 1. A roller shutter 7 is installed inside the unwinding component 6. A counterweight magnet 8 is installed at the lower end of the roller shutter 7, and the counterweight magnet 8 is aligned with the fixed groove 5.
[0031] When multiple circuit boards need to be fixed, the plug-in board 2 can be pulled out from the inner side of the protective cover 1, and then multiple circuit boards can be inserted into the slots 3 at intervals. After the circuit boards are inserted, the plug-in board 2 is pushed into the inside of the protective cover 1, and then the unwinding component 6 is rotated. At this time, the roller shutter 7 will be released downward, and the two sides of the roller shutter 7 are limited inside the guide groove 4, and the lower end is weighted by the counterweight magnet 8 to keep the roller shutter 7 moving downward smoothly. Finally, the counterweight magnet 8 will fall to the internal limit of the fixed groove 5, so that the roller shutter 7 can protect the front of the protective cover 1 to prevent the circuit boards from being damaged during transportation.
[0032] Preferably, a through slot 11 is provided at the upper end of the front face of the protective cover 1 , the through slot 11 is aligned with the fixing slot 5 , and an anti-slip slot 12 is symmetrically provided on the inner wall of the lower end of the protective cover 1 .
[0033] The rolling shutter 7 can pass through the upper end of the protective cover 1 through the through slot 11, which facilitates the lifting and movement of the rolling shutter 7, and the anti-slip slot 12 provided can guide and limit the insertion plate 2.
[0034] Preferably, anti-slip sliders 21 are symmetrically installed on both sides of one end of the inserting plate 2 away from the fixing groove 5 .
[0035] The inserting plate 2 is slidably connected to the anti-slip groove 12 via the anti-slip slider 21 to prevent the inserting plate 2 from being separated from the protective cover 1 when being pulled downward.
[0036] Preferably, grooves 31 are symmetrically provided on the inner walls on both sides of the slot 3, a fixing frame 32 is provided inside the groove 31, a buffer spring 33 is installed between the fixing frame 32 and the groove 31, and an auxiliary roller 34 is provided on one side of the inner cavity of the fixing frame 32.
[0037] Two symmetrically arranged fixing frames 32 are installed opposite to each other inside the two grooves 31. When the circuit board is not inserted into the slot 3, the buffer spring 33 can pop out the fixing frame 32 so that the auxiliary rollers 34 inside the two fixing frames 32 fit together. When the circuit board is inserted into the slot 3, the fixing frame 32 will open to both sides. At this time, the buffer spring 33 will be squeezed and deformed, and the auxiliary rollers 34 will fit on both sides of the circuit board for clamping and limiting. Since the auxiliary rollers 34 are made of rubber material and the auxiliary rollers 34 and the fixing frame 32 are rotatably connected, rolling friction is formed between the auxiliary rollers 34 and the circuit board, which improves the clamping and fixing effect while avoiding damage to the circuit board surface.
[0038] Preferably, a magnetic plate 51 is installed at the bottom end of the inner cavity of the fixing groove 5.
[0039] When the counterweight magnet 8 descends into the fixing slot 5 , the magnetic attraction plate 51 can adsorb and fix the counterweight magnet 8 , and prevent the counterweight magnet 8 from detaching from the fixing slot 5 on its own.
[0040] Preferably, the unwinding assembly 6 includes an outer shell 61 and support plates 62 symmetrically installed at both ends of the outer shell 61. A roller 63 is installed in the middle of the outer shell 61. A rotating shaft 64 is provided at both ends of the roller 63 (the rotating shaft 64 can be a damping rotating shaft). A handle 65 is installed at one end of the rotating shaft 64, and the handle 65 is located on one side of the outer end of the outer shell 61.
[0041] A person can drive the rotating shaft 64 and the roller 63 to rotate by using the handle 65 . When the rolling curtain 7 is not needed, the roller 63 can be reversed so that the rolling curtain 7 is wrapped around the outside of the roller 63 .
[0042] Preferably, the rolling curtain 7 is made of an electromagnetic shielding film. In this case, the rolling curtain 7 will be stored inside the shell 61. When it needs to be used, the roller 63 can be rotated forward to release the rolling curtain 7, and the rolling curtain 7 will descend through the through slot 11.
[0043] When the circuit board is inside the protective cover 1, the roller shutter 7 made of electromagnetic shielding film can provide protection on the front of the protective cover 1, thereby improving the electromagnetic shielding effect and minimizing damage to the circuit board when encountering a strong electromagnetic field environment.
[0044] When the circuit boards are inserted, the fixing frame 32 will open to both sides, and the buffer spring 33 will be squeezed and deformed, and the auxiliary roller 34 will fit on both sides of the circuit boards for clamping and limiting. After the circuit boards are inserted, the inserting plate 2 is pushed into the inside of the protective cover 1, and then the rotating shaft 64 and the rotating roller 63 are driven to rotate forward by the handle 65. At this time, the rolling curtain 7 will be released downward through the through slot 11. When the counterweight magnet 8 at the lower end of the rolling curtain 7 falls into the fixing slot 5, the counterweight magnet 8 can be adsorbed and fixed by the magnetic plate 51. When the circuit board needs to be taken out, the handle 65 can be manually rotated in reverse so that the rolling curtain 7 is wrapped around the outside of the rotating roller 63, and the counterweight magnet 8 will also rise to the top of the protective cover 1. Finally, the inserting plate 2 is pulled out from the inside of the protective cover 1 again, and then the circuit board is removed from the slot 3.
