Embodiment 1

[0041] Embodiment 1 Referring to Fig. 1 and Fig. 2, this kind of anti-theft and anti-jumping integral structure manhole cover has at least one blind hole 11 on the front of the manhole cover 1, and the blind hole is filled with a sealant filler of the same color as the surface of the manhole cover. There is at least one downwardly convex clamping flap 12 distributed on the inner side of the edge below the well cover, and a rectangular clamping groove 13 with a side opening and a horizontal direction is opened on the side of the downwardly convex clamping flap.

[0042] The seat body bottom of this well cover seat 2 is connected with a chassis 24 that the outer diameter is larger than the seat body, and there are bolt holes 22 on the chassis top, and the inwall of the well cover seat has an annular bearing surface 23, below the annular support surface of the well cover seat inner wall corresponding to the well cover Convex shaped convex bodies 21 are distributed at intervals, an...

Embodiment 2

[0043] Embodiment 2 Referring to FIG. 3 and FIG. 4 , the above-mentioned downward convex clip 12 is rectangular, and the inner end of the slot on the side of the downward convex clip 12 is triangular. The well cover seat convex body 21 is an arc-shaped convex strip, and the end of the convex strip is triangular.

Embodiment 3

[0044] Embodiment 3 Referring to FIG. 5 and FIG. 6 , the above-mentioned downward convex clip 12 is rectangular. The inner end of the card slot on the side of the lower convex card flap 12 is arc-shaped. The ends of the convex strips are also arc-shaped.

Abstract

The invention relates to a well cover with anti-theft and anti-leaping whole structure, and anti-theft method. One blind hole at least, in which fluid sealant filler is poured, is set on the front face of well cover. One chuck petal with convex-down shape at least is set in inner side near the edge of well cover lower part. Chuck groove with horizontal direction, is cut on the side of chuck petal with convex-down shape. Convexity is set in distance on the lower part of circle bearing surface of inner side of well cover bed relative to well cover. The width of Said convexity is corresponding to the one of cut width of said chuck groove. Two exhaust holes is set on well cover or its bed. Chuck petal with convex-down shape of well cover is inserted into the gap of convexity of well cover bed and is rotated so that the all or partial convexity of inner side of well cove bed is embedded into chuck groove with convex-down of well cover. The same color filler is poured in blind hole of well cover. Well cover and its bed, as a whole structure, are clutched with each other, which can prevent well cover from its bed and have the performances such as anti-theft, anti-skid and so on.

Description

(1) Technical field [0001] The invention relates to a well cover and a well cover seat. (2) Background technology [0002] The traditional manhole cover has a through hole, and there is no longitudinal constraint between the manhole cover and the manhole cover seat. The thief can easily steal it with simple tools. After the manhole cover is stolen, the exposed wellhead becomes a trap on the road, often causing car crashes. fatal traffic accident. The traditional manhole cover is also easy to jump off the manhole cover seat when the locomotive is rolling over. When the manhole cover suddenly breaks away from the manhole cover seat, the entire body of the moving vehicle will bounce off, or fall into the wellhead, or even collide On the back or oncoming vehicle, cause the tragedy that several cars hit in a row. The existing anti-theft methods for manhole cover, one is to install various anti-theft locks between the manhole cover and the manhole cover seat, but because these l...
