[0028] In the utility model, the surface of the parts 400 is provided with a plurality of holes 410.
[0029] The bolt 100 is provided with a partition plate 200, and a blocking piece 300 is installed on the bolt 100, and the partition plate and the blocking piece cooperate to block the parts, wherein the length of the partition plate is less than the longest axis length of the part hole and greater than the shortest axis length, or the width of the partition plate is less than the longest axis length of the part hole, and the length of the partition plate is greater than the longest axis length of the part hole, so that when blocking one of the holes 410, the partition plate 200 can be inclined to pass through the hole 410, so that the partition plate 200 can be smoothly inserted into the inside of the part 400, and the partition plate 200 is provided on the bolt 100, so that the end of the bolt 100 close to the partition plate 200 is also inserted into the part 400, then the partition plate 200 is adjusted to be clamped at the hole 410, then the blocking piece 300 is screwed on the bolt 100 and tightened until the blocking piece 300 blocks the hole 410, when the extrusion force between the blocking piece 300 and the part 400 is generated, because the partition plate 200 and the blocking piece 300 are located on both sides of the part 400, the corresponding extrusion force between the partition plate 200 and the part 400 is also generated, so that when the force is removed, the blocking piece 300 still blocks the hole 410 on the part 400, so as to achieve the purpose of blocking the hole 410; when disassembling, the blocking piece 300 needs to be unscrewed from the bolt 100, then the partition plate 200 is inclined to move out relative to the hole 410, so that the waterproof blocking device for the hole 410 of the part 400 can be removed from the part 400, so that people can use it conveniently.
[0030] The blocking piece 300 includes a waterproof pad 310, a pressing plate 320 and a nut 330 installed on the bolt 100 in sequence, and the waterproof pad is located between the limiting head and the pressing plate, after the partition plate 200 is adjusted, the waterproof pad 310, the pressing plate 320 and the nut 330 need to be installed on the bolt 100 in sequence, and the nut 330 is screwed in to make the nut 330 form an extrusion force on the pressing plate 320, so that the pressing plate 320 and the part 400 can generate an extrusion force, and the hole 410 is blocked, and the waterproof pad 310 is located between the part 400 and the pressing plate 320 at this time, so that the sealing effect of the blocking piece 300 can be further improved, and the liquid flowing out through the hole 410 of the part 400 can be avoided.
[0031] Further, when the plugging member 300 is used to plug one of the holes 410, a pressing plate 320 with a proper size is selected so that the pressing plate 320 can cover the hole 410 when the hole 410 is plugged, thereby ensuring that the pressing plate 320 can completely plug the hole 410; the cross-sectional area of the water sealing pad 310 in the transverse direction is greater than the cross-sectional area of the pressing plate 320 in the transverse direction, specifically, the pressing plate 320 and the water sealing pad 310 are both circular rings, and the outer diameter of the water sealing pad 310 is greater than the outer diameter of the pressing plate 320, so that when the pressing plate 320 is pressed on the surface of the part 400, the water sealing pad 310 can smoothly seal the edge of the pressing plate 320, so as to avoid liquid overflowing from the edge of the pressing plate 320.
[0032] The bolt 100 is provided with a limiting head 110, the partition plate 200 is fixedly connected with or contactively connected with the limiting head 110, the partition plate 200 is provided with a through hole 220 for the bolt 100 to pass through, and the limiting head 110 is used to prevent the partition plate 200 from being separated from the bolt 100.
[0033] Embodiment Two
[0034] As shown in Figure 1 Figure 2 The embodiment is a fixed connection mode of the partition plate 200 and the limiting head 110 in Embodiment One.
[0035] Specifically, the partition plate 200 is welded with the limiting head 110, so as to realize the fixed connection of the partition plate 200 and the limiting head 110, thereby effectively improving the connection strength of the partition plate 200 and the limiting head 110.
[0036] Embodiment Three
[0037] As shown in Figure 3 The embodiment is a first contact connection mode of the partition plate 200 and the limiting head 110 in Embodiment One.
[0038] Specifically, the shape of the through hole 220 in the transverse section is an ellipse, and the partition plate 200 can contact with the limiting head 110; when people pass the partition plate 200 through the hole 410, the partition plate 200 can be first rotated to a predetermined angle relative to the bolt 100, so as to reduce the included angle between the partition plate 200 and the bolt 100, thereby reducing the opening degree between the partition plate 200 and the bolt 100, so that the bolt 100 has one end of the partition plate 200 and the partition plate 200 can more smoothly pass through the hole 410; further, the shape of the limiting head 110 in the transverse section is a regular hexagon, and the diameter of the inscribed circle of the limiting head 110 is greater than the width of the elliptical through hole 220 in the minor axis, so that the limiting head 110 can prevent the partition plate 200 from being separated from the bolt 100.
[0039] Embodiment Four
[0040] As Figure 5 The second embodiment is the second contact type connection between the partition plate 200 and the limiting head 110 in the first embodiment.
[0041] The central axis of the partition plate 200 divides the partition plate 200 into a left end portion 230 and a right end portion 240, the left end portion 230 and the right end portion 240 are connected by two hinges 250, the left end portion 230 and the right end portion 240 can be folded in half around the central axis of the partition plate 200, the center of the through hole 220 is located on the central axis of the partition plate 200, and the two hinges 250 are located on both sides of the through hole 220. The partition plate 200 can be in contact with the limiting head 110, when the partition plate 200 is to be inserted through the hole 410, the left end portion 230 and the right end portion 240 can be folded in the middle along the central axis of the partition plate 200, so as to reduce the included angle between the left end portion 230 and the screw rod, and also reduce the included angle between the right end portion 240 and the screw rod, so as to reduce the opening and closing degree between the partition plate 200 and the bolt 100, so that the bolt 100 has one end of the partition plate 200 and the partition plate 200 can more smoothly pass through the hole 410. Thereafter, the partition plate 200 can be unfolded so that the left end portion 230 and the right end portion 240 are in the same plane, and then the screw rod is pulled outward, so that the two ends of the partition plate 200 are abutted against the inner wall of the part 400, and then the sealing piece 300 can be installed on the bolt 100.
[0042] Further, the cross-sectional shape of the limiting head 110 is a regular hexagon, the diameter of the through hole 220 is greater than the diameter of the bolt 100 and less than the diameter of the inscribed circle of the limiting head 110, so that the limiting head 110 prevents the partition plate 200 from being separated from the bolt 100.
[0043] Embodiment five
[0044] As Figure 4 The embodiment is based on the first embodiment, and a partition pad 210 is additionally arranged.
