Technical Field

[0001] The utility model relates to the technical field of grounding protection, in particular to a grounding protection device for a microcomputer host. Background Art

[0002] When a microcomputer host is powered on and used, it needs to be connected to the live wire and the neutral wire as well as the ground wire. However, the socket in some scenarios may not be connected to the ground wire. If you want to power on through this socket, you need to use a grounding protection device, which is commonly known as a "grounding treasure" and can enhance the grounding protection for the microcomputer host, thereby realizing safe electricity use.

[0003] One side of the grounding protection device is provided with a socket. The purpose of grounding protection is achieved by inserting the plug of the microcomputer host into the socket of the grounding protection device. However, in actual use, if the wire connected to the plug is accidentally pulled, the plug may be pulled out of the socket, which may cause the microcomputer host to lose power and is not convenient for the normal use of the microcomputer host. Summary of the Utility Model

[0005] To achieve the above object, the utility model adopts the following technical scheme: A grounding protection device for a microcomputer host, including a body.

[0006] The effects achieved by the above components are as follows: By setting two clamping plates, under the action of the threaded rod, rotating the threaded rod, the threaded rod will expand and contract inside the inner wall of the extension plate. During the expansion and contraction process of the threaded rod, it will drive the clamping plate to move synchronously until the two clamping plates completely clamp the microcomputer plug, then the microcomputer plug can be completely clamped, which is beneficial to preventing the problem that the microcomputer plug is pulled out of the socket and causes the microcomputer host to lose power.

[0017] Preferably, a latch is inserted into the inner wall of the L-shaped plate, and one end of the latch is fixedly connected to one side of the extension plate.

[0018] The effect achieved by the above components is: by arranging the latch and inserting the latch into the inner wall of the L-shaped plate, the latch can further fix the L-shaped plate.

[0019] Preferably, one end of the latch is fixedly connected to a rubber block, the cross section of the rubber block is an isosceles trapezoid, and one side of the protective plate is fixedly connected to an auxiliary ring.

[0020] The effects achieved by the above components are as follows: by setting a rubber block, one end of the rubber block is smaller, which makes it easier to insert the rubber block into the L-shaped plate, while the other end of the rubber block is larger, and after the rubber block is fully inserted into the inner wall of the L-shaped plate, the L-shaped plate can be fixed, which helps prevent the L-shaped plate from escaping from the limit of the latch, and by setting an auxiliary ring, it is easier to install and remove the protective plate through the auxiliary ring.

One end of the round rod 45 is fixedly connected to a stop block 46. By providing the round rod 45, when the clamping plate 43 moves under the action of the threaded rod 42, the clamping plate 43 will drive the round rod 45 to slide synchronously on the inner wall of the extension plate 41, which can limit the clamping plate 43. At the same time, the stop block 46 can block one end of the round rod 45, which is beneficial to preventing the round rod 45 from detaching from the inner wall of the extension plate 41.

[0032] Referring to Figure 2 and Figure 3As shown, one side of the two clamping plates 43 is fixedly connected with a rubber plate 47, and one side of the rubber plate 47 is evenly provided with grooves. By providing the rubber plate 47 with grooves, the friction force on one side of the clamping plate 43 can be increased, so that the clamping plate 43 can clamp the microcomputer plug more tightly; the bottom of one side of the body 1 is fixedly connected with a rubber ring 48, and the outer surface of the rubber ring 48 is provided with a slit.

By setting the rubber block 55, one end of the rubber block 55 is smaller, which is convenient for inserting the rubber block 55 into the L-shaped plate 52, and the other end of the rubber block 55 is larger. After the rubber block 55 is fully inserted into the inner wall of the L-shaped plate 52, the L-shaped plate 52 can be fixed, which is beneficial to prevent the L-shaped plate 52 from escaping from the limit of the latch 54, and by setting the auxiliary ring 56, it is convenient to install and disassemble the protective plate 51 through the auxiliary ring 56.

[0035] Working principle: When it is necessary to fix the microcomputer plug, rotate the operation block 44 to drive the threaded rod 42 to rotate. The threaded rod 42 will expand and contract inside the inner wall of the extension plate 41. Under the limitation of the round rod 45, the threaded rod 42 will drive the clamping plate 43 to move synchronously until the rubber plates 47 on one side of the two clamping plates 43 completely clamp the microcomputer plug, then the microcomputer plug can be completely clamped. Then insert the circuit connected to the microcomputer plug into the rubber ring 48 through the slit, and the rubber ring 48 can fix the circuit connected to the microcomputer plug, thereby further fixing the microcomputer plug, which is beneficial to preventing the microcomputer plug from detaching from the jack 3 and causing the microcomputer host to lose power; When it is necessary to protect the jack 3, rotate the operation block 44 to drive the two clamping plates 43 to move away from each other to a suitable position, then attach the protection plate 51 to one side of the jack 3, insert the L-shaped plate 52 between the two clamping blocks 53, and insert the rubber block 55 into the inner wall of the L-shaped plate 52, so that the rubber block 55 and the pin 54 are inserted into the inner wall of the L-shaped plate 52. Then the pin 54 and the rubber block 55 can fix the L-shaped plate 52, and the protection plate 51 can block one side of the jack 3, which is beneficial to preventing debris from entering the inside of the jack 3 and blocking the jack 3 when the grounding protection device is not in use.
