Description

Technical Field

[0001] The utility model relates to the technical field of PCB circuit board structures, in particular to a PCB circuit board protection structure. Background Art

[0002] PCB circuit board is an important component in the electronics industry. Almost every electronic device is equipped with PCB circuit board. The existing PCB circuit board is easily impacted and worn during transportation. Therefore, it is necessary to use a protective structure to protect it. For example, in the patent number "CN218143065U" and the patent name "A protective structure for PCB circuit board", when using this device, first use a winch to release the pull rope. At this time, the spring pops open, and the distance between the clamps can be increased, so that the PCB circuit board can be conveniently placed between two adjacent clamps. Then, the pull rope is stored by the winch, and then the clamp can squeeze the spring, so that the distance between the two adjacent clamps is reduced to clamp the PCB circuit board. After clamping, since there is a cavity between the two opposite clamps on the left and right, the circuit area of ​​the PCB circuit board here will not be worn with the clamp, so as to protect the PCB circuit board. The groove can further reduce the contact area between the PCB circuit board and the clamp, thereby further reducing wear. However, the above structure still has the following problems in actual use:

[0003] The above structure clamps the PCB circuit board by reducing the distance between two adjacent clamping plates, but at this time the four corners of the PCB circuit board are still exposed. Since the four corners of the PCB circuit board are relatively fragile, they are easily damaged by collision during transportation, causing damage to the PCB circuit board and thus causing economic losses.

[0004] Therefore, we proposed that the PCB circuit board protection structure can solve the above problems well. Utility Model Content

[0005] The purpose of the utility model is to provide a PCB circuit board protection structure to solve the problem raised by the above background technology that the four corners of the PCB circuit board on the current market are relatively fragile, which makes it easy to be damaged by collision during transportation, thereby causing damage to the PCB circuit board and causing economic losses.

[0006] To achieve the above object, the utility model provides the following technical solution: a PCB circuit board protection structure, comprising a main bottom plate, a support block is fixed to the upper surface of the main bottom plate, a protective pad is bonded to the inner wall of the support block, and a PCB circuit board body is placed on the upper surface of the protective pad;

[0007] It also includes: a connecting slide bar is provided on the upper surface of the main bottom plate, and the connecting slide bar is slidably connected with the main bottom plate through a return spring, and two ends of the return spring are respectively fixed to the main bottom plate and the connecting slide bar;

[0008] A protection block is fixed to the upper end of the connecting slide rod, and four groups of protection blocks are provided. The protection blocks are wrapped around the four corners of the PCB circuit board body, and rubber pads are bonded to the inner walls of the protection blocks.

[0011] Preferably, four groups of driven gears are provided, and a rotating rod is fixed in the middle of each driven gear, and the upper and lower ends of the rotating rod are connected to the main base plate bearing, and a pull rope is wrapped around the outer side of the rotating rod, and the other end of the pull rope is fixed to the connecting slide rod.

[0012] Preferably, a damper is fixed to the upper surface of the protection block, and a soft pad is fixed to the upper end of the damper.

[0013] Preferably, a vertical rod is fixed to the upper surface of the main bottom plate, and a secondary bottom plate is slidably connected to the outer side of the vertical rod, and a protective block is provided on the upper surface of the secondary bottom plate, and a threaded rod is fixed to the upper end of the vertical rod.

[0014] Preferably, a top plate is slidably connected to the outer side of the threaded rod, and a limiting nut is threadedly connected to the outer side of the threaded rod.

[0015] Compared with the prior art, the beneficial effects of the utility model are: the PCB circuit board protection structure not only prevents the four corners of the PCB circuit board body from being damaged by external impact during transportation, thereby achieving a good protection effect and avoiding damage to the four corners of the PCB circuit board body, but also can transport multiple groups at the same time, and achieve the effect of buffering and shock absorption through the damper, thereby further achieving the protection effect. The specific contents are as follows:

[0016] (1) The protective block is wrapped around the four corners of the PCB circuit board body, and a rubber pad is bonded inside the protective block, thereby achieving the effect of protecting the four corners of the PCB circuit board body. During transportation, the four corners of the PCB circuit board body will not be damaged by external impact, thereby achieving a good protection effect and avoiding damage to the four corners of the PCB circuit board body;

[0017] (2) By placing the PCB circuit board body on the support block, the support block can support the PCB circuit board body, and by setting a protective pad, the PCB circuit board body is protected to prevent the PCB circuit board body from directly contacting the support block;

At this time, the elastic force of the reset spring drives the connecting slide rod and the protection block away from the PCB circuit board body, and then the PCB circuit board body can be taken down;

[0020] (5) When the main bottom plate shakes up and down during transportation, the vibration will be transmitted to the damper through the soft pad, and the damper will achieve the effect of buffering and shock absorption, thereby further achieving a protective effect.

[0032] The PCB circuit board body 4 is placed on the support block 2. The support block 2 can support the PCB circuit board body 4, and the inner wall of the support block 2 is bonded with a protective pad 3 to protect the PCB circuit board body 4 and prevent the PCB circuit board body 4 from directly contacting the support block 2. The worm 5 is rotated to drive the worm wheel 6 to rotate, and the rotation of the worm wheel 6 drives the fixed main shaft 7 to rotate. The main shaft 7 rotates, and the main shaft 7 drives the driving gear 8 fixed thereto to rotate. The meshing between the driving gear 8 and the driven gear 9 drives the four sets of driven gears 9 to rotate together. The rotation of the driven gear 9 drives the fixed The rotating rod 10 rotates together, so that the rotating rod 10 will reel the pull rope 11, so that the pull rope 11 pulls the connecting slide rod 12 to approach the PCB circuit board body 4, so that the connecting slide rod 12 drives the protection block 14 fixed on its upper end to approach the PCB circuit board body 4, so that the protection block 14 can be wrapped around the four corners of the PCB circuit board body 4, and the inside of the protection block 14 is bonded with a rubber pad, so as to achieve the effect of protecting the four corners of the PCB circuit board body 4, so that during transportation, the four corners of the PCB circuit board body 4 will not be damaged by external impact, so as to achieve a good protection effect and avoid damage to the four corners of the PCB circuit board body 4;

[0033] Embodiment 2: Different from Embodiment 1, this embodiment facilitates the removal of the PCB circuit board body 4. Figure 3-Figure 5 , a worm 5 is arranged on the front side of the main bottom plate 1, and the rear end of the worm 5 is connected to the main bottom plate 1 bearing, and a worm wheel 6 is meshed on the right side of the worm 5, and a main shaft 7 is fixed in the middle of the worm wheel 6, and the upper and lower ends of the main shaft 7 are connected to the main bottom plate 1 bearing, and a driving gear 8 is fixed on the outer side of the upper end of the main shaft 7, and a driven gear 9 is meshed on the outer side of the driving gear 8, and four groups of driven gears 9 are arranged, and a rotating rod 10 is fixed in the middle of the driven gear 9, and the upper and lower ends of the rotating rod 10 are connected to the main bottom plate 1 bearing, and a pull rope 11 is wound around the outer side of the rotating rod 10, and the other end of the pull rope 11 is fixed to the connecting slide rod 12;
