[0023] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model, and it is understood that, in the description of the utility model, the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the devices or elements indicated must have a particular orientation, be constructed and operated in a particular orientation, therefore, it cannot be understood as a limitation on the utility model, obviously, the described embodiments are only a part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0024] As Figure 1 , Figure 2 , Figure 3 , Figure 4 indicated, a safety inspection well, comprising an inspection well 1 and a well cover 2, the well cover 2 is detachably connected with the inspection well 1, a limiting seat 3 is fixedly connected in the inspection well 1, a pushing piece 4 is slidably arranged in the limiting seat 3, a lever assembly is further arranged in the inspection well 1, one end of the pushing piece 4 is in abutment with the well cover 2, the other end of the pushing piece 4 is in transmission connection with the lever assembly, when maintenance is carried out, the maintenance personnel separates the well cover 2 from the inspection well 1 on the ground, and then enters the inspection well, in this process, the maintenance personnel may be misoperated by a partner or a passerby, when the maintenance personnel is still in the well, the well cover 2 is covered, and the well cover 2 is often very heavy, so it is difficult for the maintenance personnel trapped in the well bottom to lift the well cover 2, and danger is prone to occur, since the inspection well 1 of the product is provided with the pushing piece 4 and the lever assembly capable of transmitting the pushing piece 4, when the well cover 2 is covered, the lever assembly can be used to transmit the pushing piece 4 to lift the well cover 2, the lever assembly comprises a top plate 5 and a pressing rod 6, as indicated in Figure 6 , the top plate 5 comprises an integral transmission part 51 and a rotating part 52, the transmission part 51 is in abutment with the pushing piece 4, the rotating part 52 is in rotating connection with the inspection well 1, the pressing rod 6 is arranged on the rotating part 52, when the lever assembly is used, the pressing rod 6 is forced to rotate the top plate 5, after the top plate 5 rotates, the transmission part 51 in abutment with the pushing piece 4 will lift the pushing piece 4, so that the pushing piece 4 slides and lifts in the limiting seat 3 to lift the well cover 2.

[0025] The rotating part 52 of the product is fixedly connected with a stand 7, the pressing rod 6 is in rotating connection with the stand 7, when the pressing rod 6 is not used, the pressing rod 6 can be rotated to one side, so as not to occupy the space in the inspection well 1, and the maintenance personnel can conveniently go up and down the inspection well 1, furthermore, a plurality of placing grooves 8 are formed in the inner wall of the inspection well 1, the pressing rod 6 can be extended into the placing grooves 8, when the pressing rod 6 is not needed, the pressing rod 6 is rotated and one end of the pressing rod 6 is placed in the placing groove 8, so as to effectively avoid the pressing rod 6 from shaking at will, as indicated in Figure 5 , after the well cover 2 is lifted, the pressing rod 6 can also be rotated to extend into other placing grooves 8, so that the hands are freed and the posture of the well cover 2 being lifted can be maintained, and the well cover 2 can be conveniently moved away by hands.

[0026] As indicated in Figure 2 , the pushing piece 4 is fixedly connected with a limiting ring 9, the limiting ring 9 can be in abutment with the limiting seat 3 for limiting, this design makes the pushing piece 4 always maintain at a limited height when it is not pushed by the top plate 5, that is, when the well cover 2 is closed, the end of the pushing piece 4 close to the well cover 2 can contact with the well cover 2.

[0027] For example Figure 4 As shown, a roller 10 is rotatably connected to one end of the pusher 4 near the manhole cover 2. The roller 10 abuts against the manhole cover 2. After the manhole cover 2 is lifted, it is necessary to move the manhole cover 2 away. By setting the roller 10 on the pusher 4, when the manhole cover 2 is moved away, the friction between the manhole cover 2 and the pusher 4 is converted into rolling friction between the manhole cover 2 and the roller 10, which greatly reduces the friction force and makes it easier for maintenance personnel trapped at the bottom of the manhole to push the manhole cover 2 away.

[0028] Finally, a pull ring 11 is fixedly connected to the manhole cover 2. When pushing the manhole cover 2 open, you can grab the pull ring 11 by hand to make it easier to apply force.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0030] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
