Detailed Description
The following examples are given for the detailed implementation and specific operation of the present invention, but the scope of the present invention is not limited to the following examples.
Fig. 1 is a schematic structural diagram of a rubber inspection well 40 according to an embodiment of the present invention, and as shown in fig. 1, the inspection well 40 includes: the manhole cover comprises a manhole cover body 10, an arched support member 20 and an elastic contraction member 30, wherein the cross section of the manhole cover body 10 in the horizontal direction is adaptive to the shape of a manhole mouth of a manhole 40;
an arched support piece 20 is arranged on the side surface of the manhole cover body 10 facing the manhole 40;
the arcuate support member 20 includes: the manhole cover comprises a fixing part 201, at least two supporting arms 202 and supporting legs 203, wherein the fixing part 201 is connected with one ends of the supporting arms 202, and the fixing part 201 is fixed on the side surface, facing the manhole 40, of the manhole cover body 10;
the other end of the supporting arm 202 is provided with supporting legs 203, and the two supporting legs 203 are respectively contacted with the inspection well side wall 401 of the inspection well 40; the supporting arm 202 is an arc-shaped structure protruding towards the well lid body 10; the supporting arms 202 are respectively connected with the manhole cover body 10 through the elastic shrinkage pieces 30, and the distance between the two symmetrically arranged supporting legs 203 and the side surface of the side wall 401 of the manhole is larger than the inner diameter of the manhole 40;
one end of the elastic contraction member 30 is fixedly connected with one end of the support arm 202 close to the corresponding support leg 203; the other end of the elastic contraction member 30 is connected with the well lid body 10.
When the embodiment of the invention is installed on the inspection well 40, the rubber well lid body 10 is generally positioned above, and the arch-shaped support member 20 is positioned right below the well lid body 10; under the action of the elastic shrinkage piece 30, the supporting arm 202 has a tendency of moving upwards, and the distance between the plane of the left supporting leg 203 in contact with the inspection well side wall 401 and the plane of the right supporting leg 203 in contact with the inspection well side wall 401 is larger than the inner diameter of the inspection well 40. Therefore, the two symmetrically arranged supporting legs 203 can respectively abut against the inspection well side wall 401 of the inspection well 40. The surface of the support leg 203 contacting the manhole side wall 401 has a raised anti-slip feature to increase the friction between the support leg 203 and the manhole side wall 401. When rubber well lid body 10 receives external pressure, can take place to warp, undercut, at this moment, transmit the effort for the fixed part 201 that bow-shaped support piece 20 is right, bow-shaped support piece 20's fixed part 201 downstream, and then exert pressure to supporting legs 203 through bow-shaped support piece 20's curved support arm 202, and then transmit the effort for supporting legs 203, supporting legs 203 converts the pressure of vertical direction into the pressure of sideward direction, and then can play the supporting role to rubber well lid body 10, and then improved well lid body 10's compressive strength.
It can be understood that the two supporting legs 203 are symmetrically distributed on two sides of the fixing portion 201, and the symmetry axis of the supporting legs 203 is the central axis of the fixing portion 201 in the vertical direction.
In general, in order to further improve the reliability, the inspection well side wall 401 is usually provided with a support platform 403, the support platform 403 is located about 10-20mm below the inspection well side wall 401, which is in contact with the support legs 203, and when the manhole cover body 10 receives a large external force, the support legs 203 move downwards to prop against the support platform 403, so that the additional support force can be improved, and the reliability is improved.
