Abstract
Description
Technical Field
[0001] This utility model relates to a wear-resistant circuit board, belonging to the field of circuit board technology. Background Technology
[0002] Most existing circuit boards lack safety protection measures. Since they are often stacked together during transportation, they are prone to wear and tear on each other. Since circuit boards are mostly precision parts, wear and tear will lead to scrapping and increase costs.
[0003] For example, utility model patent CN217295585U discloses a wear-resistant circuit board, including a protective frame, a circuit board body, and a first compression spring. Two protective frames are provided. The circuit board body is inserted into the inner surface of the protective frame. A push plate is movably connected to the inner cavity of the protective frame. Sliding grooves are formed on the top and bottom of the opposite sides of the two push plates, and sliders are slidably connected to the inner surface of the sliding grooves. This utility model, by setting up a protective frame, can easily protect the circuit board body, preventing friction between the circuit boards during stacking and transportation, thus reducing the probability of wear. By setting up push rods, the first compression spring, sliders, sliding grooves, and push plates, the circuit board body can be limited and fixed within the protective frame, facilitating disassembly and maintenance. With the above structure, the circuit boards are less prone to wear during transportation.
[0004] However, the above solution has the following shortcomings in practical use: First, the above-mentioned device can only protect a single circuit board and cannot meet the requirements for placing and protecting multiple circuit boards. Furthermore, when protecting only a single circuit board, the device is small in size and light in weight. If it encounters bumps or shaking during transportation, two adjacent devices may collide or impact each other, which can easily damage the exposed surface of the circuit board and affect its quality.
[0005] Second, the above-mentioned device is equipped with two independent protective components. The two protective components are located at both ends of the circuit board, and there is no connecting part between the two protective components. When not in use, they are easy to be lost, which makes it impossible for a single protective component to be used normally. Utility Model Content
[0006] To solve the above-mentioned technical problems, this utility model provides a wear-resistant circuit board that can simultaneously accommodate and fix multiple circuit boards. On the one hand, it increases the overall weight of the device to prevent collisions or bumps between adjacent circuit boards due to bumps during transportation. On the other hand, it reduces the amount of protective devices used, thereby reducing cost losses. In addition, this device is an integrated structure to prevent loss when not in use.
[0007] The technical solution adopted by this utility model to solve its technical problem is: A wear-resistant circuit board includes a fixed plate, two movable plates symmetrically arranged on one side of the fixed plate, an adjustment mechanism comprising: a movable component disposed within the fixed plate, the movable component being movably connected to the two movable plates and used to adjust the distance between the two movable plates; a locking component disposed on one side wall of the fixed plate, the locking component being detachably connected to the movable component; clamping grooves being formed on the adjacent side walls of the two movable plates, and clamping components being disposed within the movable plates corresponding to the clamping grooves; and a fixed component detachably connected to the clamping components being disposed on the side wall of the movable plates.
[0008] In this design, the device rotates the movable component within the fixed component, and the distance between the two movable plates can be adjusted using the movable component. This allows the device to clamp and fix circuit boards of different sizes. At the same time, the clamping grooves on the side walls of the movable plates are used to clamp and fix the circuit boards. The movable plate and the fixed plate are an integral structure, so the device will not be lost when it is not in use, avoiding the problem of the device being unusable due to incomplete parts.
[0009] In addition, multiple clamping slots are evenly spaced along the height of the side wall of the movable plate in this device. Multiple clamping slots can be used to clamp and fix multiple circuit boards. The slots are spaced apart between each pair of adjacent circuit boards to avoid bumps or collisions after loading. At the same time, the overall weight of this device is also effectively reduced, reducing damage caused by bumps between adjacent circuit boards during transportation.
[0010] Preferably, the movable component includes: two movable slots formed on the side wall of the fixed plate, the two movable slots being symmetrical along the longitudinal direction, one of the movable slots being rotatably connected to a bidirectional screw, and the other movable slot being fixedly connected to a guide rod; two movable seats are fixedly connected to the side wall of each movable plate, the two movable seats being slidably disposed in the movable slots on both sides, one movable seat being threadedly connected to the bidirectional screw, and the other movable seat being slidably engaged with the guide rod.
[0011] In this design, the other end of the bidirectional screw extends to the outside of the fixed plate and a first handle is fixed to its end. The operator can drive the bidirectional screw to rotate by grasping the first handle. When the bidirectional screw rotates, it causes the two movable seats in the movable slot to move closer or further apart, thereby adjusting the distance between the two movable plates on both sides, so that the device can assemble and fix circuit boards of different sizes and specifications.
[0012] It should be explained that another movable seat is also installed on the side wall of the movable plate in this device, which is slidably connected to the guide rod. The cooperation between the movable seat and the guide rod (moving groove) can ensure the stability of the horizontal movement of the movable plate.
[0013] Preferably, the locking assembly includes: one end of the bidirectional screw extends to the outside of the fixed plate and a rotating disk is fixedly connected to its outer wall; a plurality of locking grooves are formed at equal angles on the outer peripheral wall of the rotating disk; a sliding groove is formed on the side wall of the fixed plate; a sliding rod is fixedly connected in the sliding groove; a limiting rod is sleeved on the outside of the sliding rod and slidably connected to the sliding groove; the limiting rod is inserted into the locking groove; and a spring is sleeved on the outside of the sliding rod on the side of the limiting rod away from the rotating plate.
[0014] In this design, when the spring is in its extended state, the limiting rod moves along the sliding groove to the side closer to the rotating disk, and the limiting rod is inserted into one of the corresponding locking slots. When the bidirectional screw needs to be rotated, the limiting rod is manually pulled along the sliding groove to slide away from the rotating disk and compress the spring. The limiting rod disengages from the locking slot, allowing the bidirectional screw to rotate. When the bidirectional screw rotates to a specified angle, the limiting rod is released. The rebound kinetic energy generated by the spring's reset will drive the limiting rod closer to the rotating disk, and at the same time, the limiting rod is inserted into the corresponding locking slot, restricting the rotation of the rotating disk. The rotating disk is fixed to the bidirectional screw, and the bidirectional screw does not rotate when the rotating disk does not rotate.
[0015] Preferably, multiple clamping grooves are provided and are equally spaced along the height of the side wall of the movable plate.
[0016] In this design, the clamping slots are provided in multiple ways to facilitate the assembly of multiple circuit boards by this device, thereby increasing the loading capacity of this device. This eliminates the need for excessive protective devices and reduces the cost of using protective devices.
[0017] Preferably, the clamping assembly includes: movable cavities symmetrically opened on both sides of the clamping groove and located within the movable plate; an adjusting screw is rotatably connected to one side of the movable cavity, and a guide rod is vertically fixed to the other side of the movable cavity; adjusting grooves communicating with the movable cavities are opened on the inner walls of both sides of the clamping groove; a pressure plate is provided in the clamping groove; the two ends of the pressure plate are slidably connected to the two adjusting grooves on both sides; and a threaded sleeve and a sliding sleeve are fixed to the two ends of the pressure plate, respectively; the threaded sleeve and the adjusting screw are screwed together; the sliding sleeve and the guide rod are slidably connected; and a buffer pad is also fixedly installed on the bottom wall of the pressure plate.
[0018] In this design, the top of the adjusting screw protrudes from the top of the movable plate, and a second handle is fixedly installed at its end. By manually grasping the second handle, the adjusting screw can be driven to rotate. When the adjusting screw rotates, it will drive the pressure plate to rise and fall in the clamping groove through the screw sleeve. The cooperation of the sliding sleeve and the guide rod can ensure the stability of the pressure plate during the rising and falling process. During the rising and falling process, the distance between the pressure plate and the bottom wall of the clamping groove can be adjusted to meet the clamping and fixing of circuit boards of different thicknesses.
[0019] It should be noted that by setting a buffer pad, the hard pressure of the pressure plate on the circuit board can be reduced, thereby avoiding damage to the pressure plate during clamping.
[0020] Preferably, the fixing component includes: a threaded hole is provided on the side wall of the movable plate, a locking bolt is threaded into the threaded hole, and a plurality of positioning holes at equal angles are provided on the bottom outer wall of the adjusting screw to accommodate the end of the locking bolt.
[0021] In this solution, when it is necessary to rotate the adjusting screw, the operator can manually rotate the locking bolt to make the threaded end of the locking bolt retract from the positioning hole, thereby controlling the rotation of the adjusting screw. After the adjusting screw is rotated to the specified angle, the locking bolt is tightened again so that its threaded end is inserted into the positioning hole to lock the adjusting screw, thus preventing accidental rotation of the adjusting screw from causing the pressure plate and circuit board to separate.
[0022] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This device allows for the clamping and fixing of circuit boards of different sizes by rotating the movable component within the fixed component. The movable component can adjust the distance between the two movable plates, while the clamping grooves on the side walls of the movable plates clamp and fix the circuit boards. The movable plate and the fixed plate are an integral structure, so the device will not be lost when it is not in use, avoiding the problem of the device being unusable due to incomplete parts.
[0023] 2. Multiple clamping slots are evenly spaced along the height of the side wall of the movable plate in this device. Multiple clamping slots can be used to clamp and fix multiple circuit boards. The slots are spaced apart between each pair of adjacent circuit boards to avoid bumping or impact after loading. At the same time, the overall weight of this device is also effectively reduced, reducing damage caused by bumping between adjacent circuit boards during transportation. Attached Figure Description

Detailed Implementation
[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Please see Figure 1-4This utility model provides a technical solution: A wear-resistant circuit board includes a fixed plate 1, two movable plates 11 symmetrically arranged on one side of the fixed plate 1, an adjustment mechanism 2, which has a movable component 21 disposed in the fixed plate 1, the movable component 21 being movably connected to the two movable plates 11 and used to adjust the distance between the two movable plates 11, and a locking component 22 disposed on one side wall of the fixed plate 1, the locking component 22 being detachably connected to the movable component 21, clamping grooves 3 being provided on the adjacent side walls of the two movable plates 11, and clamping components 31 being disposed in the movable plates 11 corresponding to the clamping grooves 3, and a fixed component 32 being detachably connected to the clamping components 31 being disposed on the side wall of the movable plates 11.
[0028] Specifically, this device is as follows: Figure 1 As shown, movable plates 11 can be installed on both the front and rear side walls of the fixed plate 1. At the same time, the moving groove 211 is a moving groove 211 that passes through the fixed plate 1. Movable plates 11 are fixedly installed on both ends of the moving seat 214. In this way, the number of circuit boards that can be loaded in this device can be increased, and the weight of this device can be increased to avoid shaking caused by bumps.
[0029] Furthermore, the movable component 21 includes: two movable slots 211 formed on the side wall of the fixed plate 1, the two movable slots 211 being symmetrical along the longitudinal direction, one movable slot 211 having a bidirectional screw 212 rotatably connected in it, and the other movable slot 211 having a guide rod 213 fixedly connected in it, and two movable seats 214 fixedly connected to the side wall of each movable plate 11, the two movable seats 214 being slidably disposed in the two movable slots 211 respectively, one movable seat 214 being threadedly connected to the bidirectional screw 212, and the other movable seat 214 being slidably engaged with the guide rod 213.
[0030] Specifically, in this device, one end of the bidirectional screw 212 extends to the outside of the fixed plate 1 and a first handle is fixedly installed on its end. The first handle can be easily grasped by a person and drive the bidirectional screw 212 to rotate.
[0031] Furthermore, the locking assembly 22 includes: one end of a bidirectional screw 212 extends to the outside of the fixed plate 1 and a rotating disk 221 is fixedly connected to its outer wall; a plurality of locking grooves 222 are formed at equal angles on the outer peripheral wall of the rotating disk 221; a sliding groove 223 is formed on the side wall of the fixed plate 1; a sliding rod 224 is fixedly connected in the sliding groove 223; a limiting rod 225 that is slidably connected to the sliding groove 223 is sleeved on the outside of the sliding rod 224; the limiting rod 225 is inserted into the locking groove 222; and a spring 226 is sleeved on the outside of the sliding rod 224 on the side of the limiting rod 225 away from the rotating disk 221.
[0032] Specifically, one end of the limiting rod 225 extends toward the rotating disk 221 away from the fixed plate 1 and extends beyond the rotating disk 221. This is to facilitate the staff to grasp the limiting rod 225 and control the limiting rod 225 to slide in the sliding groove 223.
[0033] Furthermore, multiple clamping grooves 3 are provided, and they are equally spaced along the height of the side wall of the movable plate 11.
[0034] Furthermore, the clamping assembly 31 includes: movable cavities 311 symmetrically opened on both sides of the clamping groove 3 and located within the movable plate 11; an adjusting screw 312 is rotatably connected in one movable cavity 311, and a guide rod 313 is vertically fixed in the other movable cavity 311; adjusting grooves 314 communicating with the movable cavities 311 are opened on the inner walls of both sides of the clamping groove 3; and a pressure plate 315 is provided in the clamping groove 3; the two ends of the pressure plate 315 are slidably connected to the two adjusting grooves 314 respectively; and a threaded sleeve 316 and a sliding sleeve 317 are fixedly connected to the two ends of the pressure plate 315 respectively; the threaded sleeve 316 is screwed to the adjusting screw 312; the sliding sleeve 317 is slidably connected to the guide rod 313; and a buffer pad 318 is also fixedly installed on the bottom wall of the pressure plate 315.
[0035] Specifically, the buffer pad 318 in this device is made of rubber, which has good elasticity. When the pressure plate 315 is pressed down, the buffer pad 318 deforms and can absorb the pressure, preventing the pressure plate 315 from directly contacting the circuit board surface and preventing pressure damage to the circuit board surface.
[0036] Furthermore, the fixing component 32 includes: a threaded hole 321 is provided on the side wall of the movable plate 11, a locking bolt 322 is internally threaded into the threaded hole 321, and a plurality of positioning holes 323 at equal angles are provided on the bottom outer wall of the adjusting screw 312 to accommodate the ends of the locking bolts 322.
[0037] Specifically, to prevent the locking bolt 322 from being lost, a limiting ring can be fixedly installed on the outside of the locking bolt 322. The limiting ring is located on one side of the adjusting screw 312 and is spaced apart from the adjusting screw 312. The distance between the limiting ring and the adjusting screw 312 must be sufficient to allow the end of the locking bolt 322 to be completely withdrawn from the positioning hole 323.
[0038] The workflow of this embodiment is as follows: By rotating the bidirectional screw 212, the moving seat 214 is driven to move horizontally within the moving groove 211, thereby adjusting the distance between the two movable plates 11. At the same time, the two ends of the circuit board are placed in the clamping grooves 3 on both sides respectively. Then, by rotating the adjusting screw 312, the screw sleeve 316 and the pressure plate 315 are controlled to rise and fall within the adjusting groove 314, so that the buffer pad 318 at the bottom of the pressure plate 315 contacts the top surface of the circuit board, thereby pressing and fixing the circuit board.
