When the protective cover 200 abuts against the first limiting portion 111, the protective cover 200 is located directly above the opening. When the protective cover 200 abuts against the second limiting portion 112, the protective cover 200 is located outside the opening to open the opening.

[0130] like Figure 6 As shown, in this embodiment, an optical axis portion 311 is disposed at the upper end of the threaded rod 310 , and the bottom surface of the optical axis portion 311 is higher than the top surface of the cover body 100 .

[0131] When in use, the driving block 230 can drive the protective cover 200 to rise and fall by twisting the rotating threaded rod 310. When the protective cover 200 rises and moves to the upper limit position of the driving member 300, the protective cover 200 is already located directly above the outer side of the opening. At this time, the driving block 230 is located at the optical axis portion 311. The protective cover 200 can be manually pushed to rotate around the threaded rod 310, thereby realizing the opening and closing of the opening.

[0132] When the protective cover 200 needs to be lowered, the protective cover 200 is first pushed below the opening so that the protective cover 200 abuts against the first limit portion 111, and then the knob 320 is rotated. The protective cover 200 can be lowered through the relative action of the external thread on the threaded rod 310 and the internal thread on the driving block 230.

[0133] It should be noted that when the upper limit position is lowered, in order to achieve threaded connection between the threaded rod 310 and the drive block 230, the protective cover 200 is pushed below the opening, and when the knob 320 is rotated, downward pressure can be artificially applied to the protective cover 200.

[0134] Example 5

[0135] Embodiment 5 Based on the above embodiment, the specific structure of the driving member 300 in the protection structure of the terminal 500 is further designed.

[0136] like Figure 1-4 As shown, a terminal 500 protection structure:

[0137] It includes an upper cover 400 on which a terminal post 500 is installed;

[0138] It includes a cover body 100 and a protective cover 200;

[0139] The cover 100 is mounted on the upper cover 400. The top surface of the cover 100 is provided with an opening above the terminal 500. The opening is provided with a cylinder 120 extending toward the bottom surface of the cover 100. The cylinder 120 is sleeved outside the terminal 500.

[0140] The protective cover 200 is disposed in the cylinder 120, and the cover body 100 is provided with a driving member 300 for driving the protective cover 200 to rise, fall and rotate;

[0141] When the protective cover 200 is at the lower limit position of the driving member 300, the protective cover 200 is disposed on the terminal 500;

[0142] When the protective cover 200 is at the upper limit position of the driving member 300, the bottom surface of the protective cover 200 is higher than the top surface of the cover body 100, and the protective cover 200 can rotate relative to the cover body 100 to open and close the opening.

[0143] In this embodiment, the driving member 300 is a vertically placed threaded rod 310;

[0144] The threaded rod 310 is disposed outside the cylinder 120, the upper end of the threaded rod 310 penetrates the top surface of the cover 100, and the lower end of the threaded rod 310 is rotatably connected to the upper cover 400;

[0145] The outer periphery of the protection cover 200 is provided with a driving block 230, and the driving block 230 is threadedly matched with the threaded rod 310;

[0146] The outer periphery of the cylinder 120 is provided with a lifting guide groove penetrating through the top surface of the cover body 100 , and the driving block 230 is arranged in the lifting guide groove.

[0147] In this embodiment, in order to reduce the overall size of the cover body 100 , a sink 110 is provided on the top surface of the cover body 100 . When the protective cover 200 is at the upper limit position, the protective cover 200 is higher than the bottom surface of the sink 110 and lower than the top surface of the sink 110 .

[0148] It should be noted that the sink 110 has a first limiting portion 111 and a second limiting portion 112, and the protective cover 200 is located between the first limiting portion 111 and the second limiting portion 112. When the protective cover 200 abuts against the first limiting portion 111, the protective cover 200 is located directly above the opening. When the protective cover 200 abuts against the second limiting portion 112, the protective cover 200 is located outside the opening to open the opening.

[0149] like Figure 7 As shown, in this embodiment, an optical axis portion 311 is disposed at the upper end of the threaded rod 310 , and the bottom surface of the optical axis portion 311 is higher than the top surface of the cover body 100 .

[0150] like Figure 7 As shown, in this embodiment, a spring 330 and a pressure plate 340 are sleeved on the optical axis portion 311, and the pressure plate 340 is connected to the knob 320 via the spring 330. The spring 330 is located between the pressure plate 340 and the knob 320. The upper end of the spring 330 is fixedly connected to the knob 320, and the lower end of the spring 330 abuts against the pressure plate 340.

[0151] At least two convex portions 341 are evenly distributed on the circumference of the bottom surface of the pressing plate 340;

[0152] The top surface of the driving block 230 is provided with a concave portion 231 corresponding to the convex portion 341 one by one;

[0153] The convex portion 341 can be embedded in the concave portion 231 .

[0154] When in use, the threaded rod 310 is screwed to make the driving block 230 drive the protective cover 200 to rise and fall. When the protective cover 200 rises and moves to the upper limit position of the driving member 300, the driving block 230 is located at the optical axis portion 311, the spring 330 is compressed, the pressing plate 340 is pressed on the driving block 230, and the card slot 410 is inserted into the sink 110. At this time, when the knob 320 is rotated again, the pressing plate 340 will drive the driving block 230 to rotate around the threaded rod 310, thereby realizing the opening and closing of the opening.

[0155] When the protective cover 200 needs to be lowered, the knob 320 is rotated to rotate the protective cover 200 below the opening so that the protective cover 200 abuts against the first limit portion 111. At this time, the pressure plate 340 provides downward pressure on the drive block 230. Then the knob 320 is rotated to achieve the lowering of the protective cover 200 through the relative action of the external thread on the threaded rod 310 and the internal thread on the drive block 230.
