The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are described herein for the purpose of illustration and explanation and not limitation.
Example 1
As shown in fig. 1-5, the utility model provides a nodular cast iron well lid with an anti-theft function, which comprises a support seat main body 1, and is characterized in that an end cover main body 2 is arranged at the top of the support seat main body 1, four locking mechanisms 3 are arranged on the end cover main body 2, the locking mechanisms 3 are arranged in a rectangular shape, the support seat main body 1 comprises a well lid seat 11, a placing groove 13, an annular protrusion 14 and a sliding groove 15 are arranged on the inner side of the well lid seat 11, a fixing member 5 is movably connected to the inner side of the sliding groove 15, the end cover main body 2 comprises a well lid 21, a long through hole 22, a countersunk hole 23 and a rectangular protrusion 24 are arranged on the well lid 21, the cross section of the rectangular protrusion 24 is in a rectangular structure, the locking mechanism 3 comprises a rotating end 31, a fixing end 32 is arranged at the bottom end of the rotating end 31, the fixing member 5 comprises a locking block 51, and an opening 52 is arranged on the inner side of the locking block 51.
Further, the top of the manhole cover seat 11 is further provided with a reinforcing rib 12, and the structural design of the reinforcing rib 12 is used for increasing the overall structural strength of the support seat main body 1.
The cross-sectional shape of spout 15 and mounting 5 looks adaptation, and mounting 5 and spout 15 welding are fixed mutually, and spout 15 is used for the installation of mounting 5, and mounting 5 is used for restricting locking mechanism 3.
The rotating end 31 includes an extending end 311, a groove is disposed at the top of the extending end 311, a boss 312 is disposed at the center of the bottom of the extending end 311, and the inner diameter of the counter bore 23 is matched with the outer diameter of the extending end 311.
The fixed end 32 comprises a sleeve 321, the sleeve 321 is of a hollow structure, the inner diameter of the sleeve 321 is matched with the outer diameter of the boss 312, a locking blocking piece 322 which is horizontally arranged is arranged on the circumference of the sleeve 321, and the locking mechanism 3 is used for limiting the opening and closing state of the well lid.
O type sealing washer 4 has been placed at the top of standing groove 13, and O type sealing washer 4 adopts the polyurethane material, and O type sealing washer 4 is used for improving the waterproof nature of this well lid.
Specifically, this theftproof type well lid 3's fixed mode: correspondingly installing the rotating end 31 at the counter sink 23, then pressing the fixed end 32 to the outer side of the boss 312 by external force, and after the rotating end 31 and the fixed end 32 are correspondingly installed, fixing the fixed end 32 and the rotating end 31 by an over-fit fixing mode or welding; this theftproof type well lid mounting 5's fixed mode: after the supporting seat main body 1 is integrally manufactured, the fixing piece 5 is inserted into the whole supporting seat main body 1 along the direction of the sliding groove 15, and when the fixing piece 5 is inserted into the highest position of the sliding groove 15, the sliding groove 15 and the fixing piece 5 are fixed in a welding mode; this theftproof type well lid open, closed state: as shown in fig. 5. In the opened state, i.e. the side of the fixed end 32 is in contact with the side of the rectangular protrusion 24, and the fixed end 32 is separated from the inner side of the fixing member 5, the main body 2 of the end cap is not restrained by the locking mechanism 3 and can be lifted up in the vertical direction.

When the locking mechanism 3 rotates from the closed state to the fully opened state, the locking catch 322 will touch the rectangular protrusion 24, and the personnel will obtain the relevant force feedback, and when the locking mechanism 3 cannot be continuously twisted, i.e. fully opened, the personnel can know that the end cover main body 2 is in the openable state, and finally the personnel can lift the whole end cover main body 2 through the long through hole 22. Similarly, when the person completes the related work and needs to cover the manhole cover, the locking mechanism 3 will rotate from the fully open state to the closed state, the locking stop piece 322 will touch the sidewall of the opening 52, the person will also obtain the related force feedback, and the person cannot continue to twist the locking mechanism 3, that is, the closed state.
This well lid can effectively solve ordinary well lid and can open, lead to the problem of property loss and road safety at will. Under the combined action of the locking mechanism and the fixing piece, the anti-theft manhole cover can improve the anti-theft property of the manhole cover, and non-equipment maintenance personnel are difficult to rotate the locking mechanism to open the manhole cover; the anti-theft well cover adopts a locking mode, has a simple structure and is convenient to use; the anti-theft well cover has no excessive mechanical structure, and does not cause excessive impression on later-stage well descending maintenance and drainage.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the utility model. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
