Description

Technical Field

[0001] This utility model relates to the field of circuit board design technology, and more specifically to circuit board spacers. Background Technology

[0002] In electrical equipment with many electronic components, there are usually multiple circuit boards. Since some small electrical equipment (such as frequency converters) have relatively high requirements for their size, their area occupied usually cannot be too large. The industry generally adopts the method of stacking multiple circuit boards and placing them at a certain interval to meet the requirements of their area and appearance.

[0003] In existing technologies, when stacking two circuit boards, plastic or copper pillars are typically inserted into the corresponding mounting holes of the two circuit boards and then fixed with screws, or elastic clips are used to clamp the mounting holes of the circuit boards. However, while screw fixing is stable, it is cumbersome and requires auxiliary tools for installation. Elastic clip installation is less stable, and although the installation is simple, disassembly requires workers to squeeze the elastic clips, making it inconvenient to use. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a circuit board spacer to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: a circuit board spacer, comprising a spacer, with limiting components at both ends of the spacer, each limiting component including two trapezoidal limiting blocks symmetrically arranged and movably mounted on the spacer, each trapezoidal limiting block having a snap-fit ​​portion between itself and the spacer for snap-fit ​​mounting the circuit board, and each end of the spacer being provided with a pressing component, each pressing component including a push rod movably disposed within the spacer, the outer periphery of the push rod being provided with an operating component for driving the push rod to slide, and both trapezoidal limiting blocks being controlled by the lifting and lowering movement of the push rod.

[0006] Preferably, the extrusion assembly further includes a compression spring, a lifting groove is provided at the end of the spacer column, the push rod is slidably installed in the lifting groove, one end of the compression spring is fixedly installed at the bottom end of the push rod, and the other end of the compression spring is fixedly installed on the inner wall of the bottom end of the lifting groove.

[0007] Preferably, the operating component includes an operating block, and the inner wall of the lifting groove is provided with a lifting hole. The operating block is slidably installed in the lifting hole. Both sides of the operating block are arc-shaped. The inner wall of the operating block is fixedly connected to the outer wall of the top rod.

[0008] Preferably, the two trapezoidal limiting blocks have arc-shaped grooves on their sides that are close to each other, and the top rod is adapted to the two arc-shaped grooves.

[0009] Preferably, the limiting component further includes two arc-shaped blocks, both of which are fixedly installed at the ends of the spacer column. The inner periphery of both arc-shaped blocks is in contact with the outer periphery of the top rod. The top of each arc-shaped block is provided with a mounting groove, and the inner walls of the two mounting grooves are provided with circular grooves. The inner walls of the four circular grooves are respectively rotatably mounted with two mounting shafts. Each of the two mounting shafts is provided with two elastic units, and the two trapezoidal limiting blocks are respectively fixedly sleeved on the two mounting shafts.

[0010] Preferably, the elastic unit includes a torsion spring, one end of which is fixedly installed on the outer peripheral wall of the mounting shaft, and the other end of which is fixedly installed on the inner peripheral wall of the circular groove.

[0011] Preferably, two extrusion blocks are fixedly installed at the end of the top rod, and each of the two trapezoidal limiting blocks has an extrusion groove on its top, with the two extrusion blocks respectively matching the two extrusion grooves.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model, by pulling down the operating block, drives the top rod to move into the lifting groove, thereby driving the two extrusion blocks to move down synchronously and enter the two extrusion grooves respectively. When the extrusion blocks contact the bottom inner wall of the extrusion groove, the upper end face of the top rod moves completely below the trapezoidal limiting block, releasing the extrusion limiting of the two trapezoidal limiting blocks. At this time, the top rod drives the two extrusion blocks to continue to move down, which will extrude the two trapezoidal limiting blocks, thereby causing the two trapezoidal limiting blocks to rotate 90 degrees in opposite directions synchronously. This setting can quickly insert the circuit board mounting hole into the mounting position, thereby realizing the installation operation, and the overall installation operation is convenient.

[0014] 2. In this utility model, by releasing the limiting position of the operating block, the compression spring resets due to its elasticity, thereby driving the top rod to move upward and reset. When the two pressing blocks move upward, they release the pressure on the trapezoidal limiting block, allowing the trapezoidal limiting block and the mounting shaft to reset under the elastic action of the torsion spring. At this time, the outer wall of the top rod once again fits against the arc-shaped groove of the two trapezoidal limiting blocks, achieving a fixed limiting function and preventing them from flipping over. Through the action of the two trapezoidal limiting blocks, the circuit board is fixed, greatly improving the stability after installation. Attached Figure Description

[0020] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0021] Figures 1-4 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-4 The present invention will be further described below.

[0022] Specifically, the circuit board spacer includes spacer 1, with limit components at both ends of spacer 1. The limit components include two trapezoidal limit blocks 3, which are symmetrically arranged and movably mounted on spacer 1. Each trapezoidal limit block 3 has a snap-fit ​​part between it and spacer 1 for snap-fit ​​mounting of the circuit board. Each end of spacer 1 is provided with a pressing component, which includes a push rod 2. The push rod 2 is movably mounted inside spacer 1, and an operating component is provided on the outer periphery of the push rod 2 for sliding. The two trapezoidal limit blocks 3 are controlled by the lifting and lowering movement of the push rod 2.

[0023] The extrusion assembly also includes a compression spring 6. The end of the spacer column 1 is provided with a lifting groove. The push rod 2 is slidably installed in the lifting groove. One end of the compression spring 6 is fixedly installed at the bottom end of the push rod 2, and the other end of the compression spring 6 is fixedly installed on the inner wall of the bottom end of the lifting groove. By setting the compression spring 6, after the limit on the push rod 2 is released, the elastic action of the spring 6 can drive the push rod 2 to achieve the reset function.

[0024] The operating component includes an operating block 4. The inner wall of the lifting groove is provided with a lifting hole 5. The operating block 4 is slidably installed in the lifting hole 5. Both sides of the operating block 4 are arc-shaped. The inner wall of the operating block 4 is fixedly connected to the outer wall of the top rod 2. By setting the operating block 4, the operator can drive the top rod 2 to move synchronously when sliding the operating block 4 through its connection with the top rod 2.

[0025] Both trapezoidal limiting blocks 3 have arc-shaped grooves on their sides that are close to each other. The top rod 2 is adapted to the two arc-shaped grooves. By setting the arc-shaped grooves on the trapezoidal limiting blocks 3, the outer wall of the periphery of the top rod 2 can fit into the arc-shaped grooves, thereby achieving the limiting function and preventing the trapezoidal limiting blocks 3 from flipping after they are snapped onto the circuit board.

[0026] The limiting assembly also includes two arc-shaped blocks 7, both of which are fixedly installed at the ends of the spacer column 1. The inner walls of the two arc-shaped blocks 7 are in contact with the outer walls of the top rod 2. The top of each of the two arc-shaped blocks 7 is provided with a mounting groove 8, and the inner walls of the two mounting grooves 8 are provided with circular grooves. The inner walls of the four circular grooves are respectively rotatably mounted with two mounting shafts 11. Each of the two mounting shafts 11 is provided with two elastic units. The two trapezoidal limiting blocks 3 are respectively fixedly sleeved on the two mounting shafts 11. Through the setting of the mounting shafts 11, the trapezoidal limiting blocks 3 can realize the rotation function, thereby facilitating the installation and disassembly of the circuit board.

[0027] The elastic unit includes a torsion spring 12. One end of the torsion spring 12 is fixedly installed on the outer peripheral wall of the mounting shaft 11, and the other end of the torsion spring 12 is fixedly installed on the inner peripheral wall of the circular groove. By setting the torsion spring 12, when the trapezoidal limit block 3 and the mounting shaft 11 are flipped, a reset force is applied by the torsion spring 12. When the limit on the trapezoidal limit block 3 is released, its elastic action can drive the trapezoidal limit block 3 to achieve the reset function.

[0028] Two extrusion blocks 10 are fixedly installed at the end of the top rod 2. Extrusion grooves 9 are opened on the top of the two trapezoidal limit blocks 3. The two extrusion blocks 10 are adapted to the two extrusion grooves 9 respectively. With the setting of the two extrusion blocks 10 and the two extrusion grooves 9, when the top rod 2 moves downward, it can drive the two extrusion blocks 10 to move downward to extrude the trapezoidal limit blocks 3, thereby causing the two trapezoidal limit blocks 3 to flip.

[0029] The working principle and usage process of this utility model are as follows: Pulling down the operating block 4 causes the top rod 2 to move into the lifting groove, compressing the compression spring 6. When the top rod 2 moves downward, it causes the two extrusion blocks 10 to move downward synchronously and enter the two extrusion grooves 9 respectively. When the extrusion blocks 10 contact the bottom inner wall of the extrusion groove 9, the upper end face of the top rod 2 moves completely below the trapezoidal limiting block 3, releasing the extrusion limiting of the two trapezoidal limiting blocks 3. At this time, the top rod 2 drives the two extrusion blocks 10 to continue moving downward, extruding the two trapezoidal limiting blocks 3, thereby causing the two trapezoidal limiting blocks 3 to rotate 90 degrees in the opposite direction synchronously. This setting allows the circuit board mounting hole to be quickly inserted into the mounting position, thereby realizing the installation operation. The overall installation operation is convenient.

[0030] After the circuit board mounting hole is inserted into the mounting part, the limiting position of the operating block 4 is released. At this time, the compression spring 6 returns to its original position through elastic action, thereby driving the top rod 2 to move upward and return to its original position. When the two pressing blocks 10 move upward, the pressing on the trapezoidal limiting block 3 is released, so that the trapezoidal limiting block 3 and the mounting shaft 11 return to their original position under the elastic action of the torsion spring 12. At this time, the outer wall of the periphery of the top rod 2 is once again in contact with the arc groove of the two trapezoidal limiting blocks 3, realizing the fixed limiting function and preventing it from flipping. Through the action of the two trapezoidal limiting blocks 3, the circuit board is fixed, which greatly improves the stability after installation.

[0031] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
