DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1-5 As shown, an electrical protection pressure plate comprises a pressure plate body 1, a connecting block 2 is installed on the outer surface of the pressure plate body 1, an elastic mechanism 3 is arranged on the upper surface of the connecting block 2, a connecting piece 4 and a limiting mechanism 5 are arranged on the upper part of the elastic mechanism 3, a card slot 6 is opened at the end of the connecting piece 4, and the number of the card slots 6 is two, the elastic mechanism 3 comprises a fixed shell 301, the lower surface of the fixed shell 301 is fixedly connected to the connecting block 2, the inner wall of the fixed shell 301 is rotatably connected to a rotating rod 302, the outer surface of the rotating rod 302 is fixedly connected to the connecting piece 4, a coil spring 303 is arranged inside the fixed shell 301, one end of the coil spring 303 is fixedly connected to the outer surface of the rotating rod 302, and the other end of the coil spring 303 is fixedly connected to the inner wall of the fixed shell 301, and the rotating rod 302 can be driven to rotate by the coil spring 303.

[0024] The limiting mechanism 5 includes a stopper 501, the lower surface of the stopper 501 is fixedly connected to the fixed shell 301, the upper surface of the stopper 501 is fixedly connected to a circular plate 502, the connecting piece 4 is sandwiched between the circular plate 502 and the fixed shell 301, the inner wall of the circular plate 502 is rotatably connected to the rotating rod 302, the upper surface of the rotating rod 302 is fixedly connected to a rotating block 14, the inner wall of the connecting piece 4 is provided with a stopper groove 503, the outer surface of the stopper 501 is slidably connected to the stopper groove 503, the number of the stopper groove 503 and the number of the stopper 501 are two, and when the connecting piece 4 rotates with the rotating rod 302 as the center, the stopper 501 just enters the interior of the stopper groove 503.

[0025] The connecting piece 4 is provided with an extrusion plate 7 above the card slot 6, and an extrusion mechanism 8 is provided on the upper surface of the extrusion plate 7. An inclined block 9 is fixedly connected to the lower surface of the extrusion plate 7. One side of the inclined block 9 is an inclined surface, and the other side is a vertical surface. A connecting end 10 is provided inside the pressure plate body 1. There are two connecting ends 10. The other end of the connecting end 10 passes through the pressure plate body 1 and is connected to the external protection circuit. A groove 11 is provided on the upper part of the connecting end 10. The outer surface of the inclined block 9 is slidably connected to the card slot 6. The outer surface of the inclined block 9 is also slidably connected to the groove 11. The shape of the groove 11 is the same as that of the lower part of the inclined block 9. When the inclined block 9 hits the bottom wall of the groove 11, there is a distance between the extrusion plate 7 and the upper surface of the connecting end 10. The distance is greater than the thickness of the connecting piece 4, so that the extrusion plate 7 will not block the connecting piece 4. When the connecting piece 4 is closed, the inclined block 9 can be squeezed under the extrusion plate 7.

[0026] The upper surface of the pressure plate body 1 is fixedly connected to a shell 12, and there are two shells 12. The shell 12 protects the internal components and increases the aesthetic effect. The extrusion mechanism 8 includes a sliding rod 801, the lower surface of the sliding rod 801 is fixedly connected to the extrusion plate 7, the upper surface of the sliding rod 801 is fixedly connected to a pull ring 802, the outer surface of the sliding rod 801 is slidably connected to the shell 12, and the outer surface of the sliding rod 801 is sleeved with a spring 803, one end of the spring 803 is fixedly connected to the shell 12, and the other end of the spring 803 is fixedly connected to the extrusion plate 7.

The arc-shaped openings 13 on the two shells 12 are not arranged on the same side, and the arc-shaped opening 13 allows the connecting piece 4 to enter the interior of the shell 12.

[0027] It should be noted that in actual use of the device, when it is necessary to disconnect the connecting piece 4, the two pull rings 802 are pulled upward, and the pull ring 802 drives the extrusion plate 7 to move upward through the sliding rod 801, and the extrusion plate 7 drives the inclined block 9 to move upward, so that the inclined block 9 moves upward away from the groove 11 and the slot 6, and the inclined block 9 no longer restricts the connecting piece 4. Under the action of the coil spring 303, the rotating rod 302 is driven to rotate, and the rotating rod 302 drives the connecting piece 4 to rotate, so that both ends of the connecting piece 4 are separated from the connecting end 10, and at the same time, the block 501 slides into the inside of the blocking groove 503, and the connecting piece 4 is blocked by the block 501, so that the connecting piece 4 can only rotate 90 degrees, and there is no need to tighten the bolts, thereby achieving the effect of easy disconnection.

[0028] When the connecting piece 4 needs to be closed, the rotating block 14 is directly twisted. The rotating block 14 drives the connecting piece 4 to rotate 90 degrees through the rotating rod 302, so that the end of the connecting piece 4 enters the interior of the shell 12 from the arc-shaped opening 13, and the end of the connecting piece 4 squeezes the inclined surface on the inclined block 9, so that the inclined block 9 moves upward. When the slot 6 moves to the lower part of the inclined block 9, the squeezing plate 7 and the inclined block 9 are reset under the action of the spring 803, so that the inclined block 9 is inserted into the slot 6 and the groove 11, and the connecting piece 4 is clamped by the inclined block 9, so that the connecting piece 4 is fixed, and the two connecting ends 10 are connected by the connecting piece 4, thereby achieving the effect of easy closing.
