technical field

The utility model relates to the technical field of municipal facilities, in particular to an integrated anti-subsidence and anti-fall manhole cover and an unlocking device thereof.

Background technique

Because the manhole cover will be lost due to various reasons, when the manhole cover is missing, it is easy for pedestrians to fall into the well hole and have an accident. The anti-fall net catches the danger that is not easy to get out.

Therefore, on the basis of the anti-fall net, a new anti-fall well cover design has been produced, such as the disclosed technical content of Chinese patent CN205369317U: a new type of anti-fall well cover, including a well seat and a cover body matched with the well seat, and the inner wall of the well seat There is a support frame for supporting the cover body. There is an anti-fall inner cover in the well base. There are multiple rotating protrusions evenly distributed on the anti-fall inner cover. The inner wall of the well base can be detachably connected to multiple support blocks. The number of shanks is the same, and there is a long hole on the support block. One end of the long hole is provided with a limit hole, and the other end is provided with a protruding hole. diameter.

Although the above-mentioned technical solution solves the safety problem caused by the original anti-fall net, its anti-fall inner cover needs a plurality of rotating lugs to be fixed, which is very inconvenient to install and disassemble, and its well cover is easy to be stolen without a safety device.

Contents of the invention

The technical problem to be solved by the utility model is to provide an integrated anti-subsidence and anti-fall manhole cover with simple structure and effective anti-theft. In order to achieve the above object, the technical solution adopted in the utility model is:

An integrated anti-settling and anti-falling manhole cover includes a cover body and a base that are rotatably connected to each other. A latch lock is provided on the inside of the cover body, a boss is provided on the base, and an inner cover is placed on the base. The outer ring of the inner cover is fixed against the boss. The shelving setting of the inner cover can realize the easy installation and removal of the inner cover, and the inner cover can be replaced or cleaned regularly according to the actual use situation, which is simple and convenient.

On the basis of adopting the above technical scheme, the utility model can also adopt the following further schemes:

Wherein, the latch lock comprises a screw rod 42 and a pressing rod 43 arranged on the screw rod 42, the screw rod 42 passes through a fixing ring 44 arranged on the connecting piece 41 and is fixed on the connecting piece 41, and the screw rod 42 is connected between the pressing rod 43 and the fixing ring. A spring 45 is sleeved between 44 . In order to facilitate unlocking, the connecting piece 41 defines a locking hole 46 penetrating through the cover body 1 in front of the pressing rod 43 .

The base 2 is provided with a boss 21 , and an inner cover 3 is rested on the base 2 , and the outer ring 31 of the inner cover 3 is fixed against the boss 21 . Wherein, the base 2 is provided with a fixing groove 22, and the fixing groove 22 is provided with a mounting seat 5, and a connecting plate 6 is fixed inside the cover body 1, and the connecting plate 6 is connected to the mounting seat 5 through a connecting seat 7. The connecting plate 6 and the cover body 1 can be fixedly connected by bolts to facilitate disassembly.

Further, both sides of the upper end of the connection base 7 are respectively provided with fixing blocks 71, the fixing blocks 71 are provided with through holes 72, and both sides of the front end of the connecting plate 6 are provided with latches 61, and the latches 61 are inserted into the through holes 72 of the fixing block 71 to The connecting plate 6 can be rotated relative to the connecting seat 7 .

Further, two mounting bases 5 are provided and fixed on both sides of the fixing groove 22 respectively.

Further, a protruding reinforcing piece 73 is provided below the connecting base 7, and the reinforcing piece 73 can be fixed to the base 2 by bolts.

Further, a clip 8 is fixed at the connecting end of the connecting base 7 and the cover 1 , and a convex edge 23 is provided above the boss 21 of the base 2 , and the clip 8 can be fixedly engaged with the convex edge 23 . Wherein, the clip 8 is a two-fold sheet structure, wherein one bending angle is 90°, and the other bending angle is greater than 90° and less than 180°.

As shown in FIG. 8 , the inner cover 3 is a cover body concaved from the outer ring 31 of the inner cover 3 , and the cover body is composed of a bottom surface 32 and an inclined side wall 33 .

Wherein, two assembling openings 331 penetrating through the outer ring 31 are opened on the side wall 33 , and the two assembling openings 331 are oppositely arranged. Since the assembly opening 331 is in contact with the base 2 and the cover body 1 , in order to increase the strength of the assembly opening 331 , the edge of the assembly opening 331 is thickened and protrudes outward from the side wall 33 .

Further, the side wall 33 is provided with six curved protrusions 332, the upper end of the curved protrusions 332 is flat with the outer ring 31 and the lower end is connected with the bottom surface 32, the curved protrusions 332 are arc-shaped protrusions, and the curvature of the protrusions The setting of this radian can not only make the curved convex part play the role of reinforcing rib to increase the firmness of the inner cover 3, but also can divert the inflowing rainwater mixed with impurities such as soil from the two sides of the curved convex part 332. Side diversion to ensure the smooth drainage of rainwater.
