Description

Technical Field

[0001] The utility model relates to the technical field of manhole covers, in particular to an adjustable anti-sinking manhole cover. Background Art

[0002] Manhole covers are used to cover deep wells on roads or in homes to prevent people or objects from falling. They can be divided into metal manhole covers, high-strength fiber cement concrete manhole covers, resin manhole covers, etc. according to the material. They are generally round and can be used for the connection and maintenance positions of sewers, underground pipelines, gas pipelines and other systems. They are widely used.

[0003] Existing manhole covers have the following disadvantages during use: manhole covers, especially those installed on the road, are affected by factors such as the squeezing of cars during actual use. They are prone to settlement over time, causing the installation position of the manhole cover to sink and form pits, affecting the smoothness of the road surface and the driving experience. For this reason, we propose an adjustable anti-settlement manhole cover. Utility Model Content

[0004] The main purpose of the utility model is to provide an adjustable anti-sinking manhole cover, which can provide stable support for the manhole cover through a supporting mechanism arranged inside the floor, and can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] An adjustable anti-subsidence manhole cover includes a floor and a supporting mechanism. The supporting mechanism is arranged inside the floor. The supporting mechanism includes a mounting seat, a limiting plate, a pin, a fixing frame, a spring, a connecting seat and a movable cover. The mounting seat is embedded in the floor. Limiting plates are welded on both sides of the top of the mounting seat, and pins inserted into the floor are inserted into the limiting plates. The bottom of the mounting seat is fixedly connected to the fixing frame, and the top of the fixing frame is movably connected to the connecting seat through a spring. The connecting seat is plugged with a movable cover.

[0007] Furthermore, it also includes an adjustment mechanism, and an adjustment mechanism is provided inside the fixing frame, and the adjustment mechanism includes a screw hole and a screw rod. A screw hole is opened in the vertical direction at the bottom end of the fixing frame and the screw rod is movably connected through the screw hole; for a newly installed manhole cover, the screw rod is turned along the screw hole so that there is a certain distance between the end of the screw rod and the bottom of the connecting seat. At this time, the screw rod plays a limiting role on the connecting seat to prevent the connecting seat and the movable cover from being overpressed when the car presses on them. After long-term use, as the spring elastic force ages, the screw rod can continue to be turned so that its end directly contacts the bottom of the connecting seat, and then the screw rod supports and stabilizes the connecting seat and the movable cover.

[0008] Furthermore, a socket for inserting a pin is provided inside the limit plate, and a concave hole is provided at the top of the socket, the end of the pin is placed inside the concave hole, and inclined plates are fixedly connected on both sides of the surface of the limit plate; after the pin is installed in place, its end is retracted into the concave hole and will not protrude, and at the same time, the inclined plate structure on both sides of the limit plate can reduce the impact on the stability of the car when it contacts the limit plate during driving.

[0009] Furthermore, a limiting ring is integrally formed on the bottom of the connecting seat to abut against the bottom of the mounting seat, and a supporting ring is integrally formed on the inner wall of the connecting seat to support the movable cover; the limiting ring structure limits the upward movement range of the connecting seat, and the supporting ring structure supports the movable cover.

[0010] Furthermore, the end of the screw is screwed into the interior of the spring; by twisting the screw, its position can be adjusted to achieve different functions.

[0011] Compared with the prior art, the present invention has the following beneficial effects: the mounting seat is directly installed in a suitable mounting position inside the floor, and its top is flush with the floor surface. After installation in place, a limit plate is welded at its top side position, and a pin is used to penetrate the limit plate and be driven into the floor to achieve fixation between the mounting seat and the floor. The bottom of the mounting seat is connected to the connecting seat and the movable cover by a fixing frame and a spring. During daily use, the spring supports the connecting seat and the movable cover, and uses its elastic force to keep its top always flush with the top of the mounting seat, and then flush with the floor surface, so that no settlement occurs, the road surface is kept flat, and the driving experience is improved; for the newly installed manhole cover, the screw is turned along the screw hole so that there is a certain distance between the end of the screw and the bottom of the connecting seat. At this time, the screw limits the connecting seat to prevent the connecting seat and the movable cover from being over-pressed when the car presses on them. After long-term use, as the spring elastic force ages, the screw can be continued to be turned so that its end directly contacts the bottom of the connecting seat, and then the screw supports and stabilizes the connecting seat and the movable cover.
