The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Example (b):

referring to fig. 1 and 3, a municipal administration inspection shaft structure, including detaining in inspection shaft lid 1 of inspection shaft mouth, inspection shaft lid 1 below is provided with support frame 2 of steel construction. The supporting frame 2 comprises four supporting rods 3 and a circular supporting seat 4, and the supporting rods 3 are fixed on the outer circumferential side of the supporting seat 4 at even intervals. The supporting rod 3 comprises a fixing mechanism 5 which is fixed on the wall of the inspection well to fix the supporting frame 2, and the supporting seat 4 comprises a supporting mechanism 6 which can protrude outwards and is used for being trampled by pedestrians. The supporting mechanism 6 is provided with a shrinking mechanism 7 which enables the supporting mechanism 6 to shrink inwards when being pressed by the inspection well cover 1, so that the space in the inspection well for water flow discharged into the inspection well from the water inlet of the inspection well cover 1 to pass through is increased, and meanwhile, dust, garbage and the like entering the inspection well through the water inlet of the inspection well cover 1 when the inspection well is not used are reduced to be accumulated on the supporting structure.

Referring to fig. 2 and 3, the support mechanism 6 includes a slide bar 601 and a spring 602. A plurality of first sliding grooves 401 are formed in the outer circumference of the supporting seat 4 at regular intervals in the direction toward the center of the supporting seat 4, and the sliding rod 601 is slidably connected to the first sliding grooves 401. The spring 602 is disposed in the first sliding groove 401, and one side of the spring abuts against one end of the sliding rod 601 near the center of the circle of the supporting seat 4, and the other side of the spring abuts against one end of the first sliding groove 401 near the center of the circle of the supporting seat 4. When the inspection well cover 1 exists, the contraction mechanism 7 is pressed to enable the sliding rod 601 to slide towards the circle center direction of the supporting seat 4, and the spring 602 contracts. When the contracting mechanism 7 loses the pressing, the spring 602 releases the elastic force to push the sliding rod 601 to slide in the direction away from the center of the supporting seat 4, and the sliding rod 601 protrudes outwards for the pedestrian to step on.

Referring to fig. 2, the support plates 9 of the arc-shaped steel structure are fixedly connected between the four support rods 3 by welding, and the bottom of the sliding rod 601 sliding towards the direction away from the center of the circle of the support seat 4 is lapped on the top of the support plates 9, so that the support plates 9 form a support structure for the sliding rod 601, and the support strength of the sliding rod 601 is enhanced.

Referring to fig. 1 and 3, the retracting mechanism 7 includes a rope 701 and a driving rod 702 made of a hollow cylindrical plastic material, which is beneficial to reduce the weight of the driving rod 702 and facilitate the sliding of the driving rod 702. The circle center of the supporting base 4 is provided with a second sliding slot 402 extending along the vertical direction, and the driving rod 702 is slidably connected to the second sliding slot 402. The rope 701 is inserted into the support 4, one end of the rope 701 passes through the spring 602 and is fixed to the side of the sliding rod 601 close to the driving rod 702 by knotting through the driving rod 702 in the hollow portion, and the other end is fixedly connected to the outer circumference of the driving rod 702. When the inspection well cover 1 exists, pressure is applied to the driving rod 702, so that the driving rod 702 drives the rope 701 to slide downwards in the second sliding groove 402, when the driving rod 702 slides, the rope 701 is pulled to enable the sliding rod 601 to contract towards the circle center direction of the supporting seat 4, the inner wall of the second sliding groove 402 is slightly larger than the outer diameter of the driving rod 702, and therefore a gap for the rope 701 to slide along with the driving rod 702 is reserved.

Referring to fig. 3 and 4, an end cap 403 is disposed on the top of the supporting seat 4, and the end cap 403 is fixedly connected to the supporting seat 4 by the first screw 8. When the end cover 403 is opened, the supporting mechanism 6 and the retracting mechanism 7 inside the supporting seat 4 can be conveniently installed and maintained.

Referring to fig. 1 and 4, the fixing mechanism 5 includes a fixing rod 501, and one end of the supporting rod 3 away from the supporting seat 4 is provided with a third sliding slot 301 extending toward the supporting seat 4. Dead lever 501 sliding connection is in third spout 301, and the bracing piece 3 supports dead lever 501 through second screw rod 10 and realizes the fixed connection with dead lever 501, and the one end fixedly connected with that second screw rod 10 is close to dead lever 501 is used for increasing friction and obtains rubber layer 11, and dead lever 501 keeps away from bracing piece 3 one side sliding connection in the basement wall of a well. Because the inspection well is cast by concrete, a hole groove used for sliding connection of the fixing rod 501 on the inspection well wall is reserved in advance when the inspection well is laid.

Referring to fig. 1, 2 and 3, the supporting frame 2, the fixing rod 501 and the sliding rod 601 are made of steel structures, so that the first sliding groove 401, the second sliding groove 402 and the third sliding groove 301 are formed simultaneously when the supporting frame 2 is produced. Therefore, when the supporting mechanism 6 and the retracting mechanism 7 are installed, the end cap 403 is opened to place the sliding rod 601 and the spring 602 in the first sliding slot 401, respectively, the rope 701 is threaded through the spring 602, one end of the rope 701 is fixedly connected to the sliding rod 601, the other end of the rope 701 is fixedly connected to the driving rod 702, and the driving rod 702 slides in the second sliding slot 402. Referring to fig. 4 in detail, the fixed end cover 403 is closed by the first screw 8.

The use principle is as follows:

referring to fig. 1, 3 and 4, before use, the fixing rod 501 is slidably connected to a hole groove reserved in advance on the wall of the inspection well, the fixing rod 501 is fixedly connected to the supporting frame 2 through the second screw 10, then the inspection well cover 1 is buckled, the driving rod 702 is pressed by the inspection well cover 1 to slide downwards, the driving rod 702 drives the rope 701 to pull downwards to shrink the sliding rod 601, and a space for water flow discharged into the inspection well from a water inlet of the inspection well cover 1 to pass through is increased. When inspection shaft lid 1 is lacked, when actuating lever 702 lost the suppression, spring 602 elasticity release promoted slide bar 601 and slided to keeping away from supporting seat 4 direction, and when the pedestrian stepped on the inspection shaft, slide bar 601 and support frame 2 provided the stress point of stepping on for the pedestrian jointly, prevented that the pedestrian from weighing down in the inspection shaft.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
