Description

Round anti-loosening manhole covers for road works

technical field

The utility model belongs to the field of road construction engineering, in particular to a circular anti-loosening manhole cover for road engineering.

Background technique

At present, inspection well covers are very common in daily life. They can be mainly fixed on the well frame at the mouth of the inspection well and the well cover body used to close the opening of the well frame. However, since the well cover body is only set on the well frame, in order to facilitate installation There is a clearance fit between the two, so relative movement is easy to occur, resulting in uneven force on the well frame, which is easy to cause deformation of the well frame, thereby reducing the service life of the inspection well cover.

Contents of the invention

The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide an improved circular anti-loosening manhole cover for road engineering.

In order to solve the above technical problems, the utility model takes the following technical solutions:

A round anti-loosening inspection well cover for road engineering, which includes a well frame that can be fixed at the mouth of the inspection well, a well cover body for closing the opening of the well frame, and inner walls respectively arranged on the inner wall of the opening and the periphery of the well cover body. The screw thread, the outer thread, and the connection part provided on the well cover body to facilitate the connection with the joint of the tightening tool, wherein the inner thread and the outer thread are screwed together.

Preferably, the well frame further includes a bearing portion located at the bottom of the opening, and when the well cover body is flush with the upper surface of the well frame, the bearing portion supports the bottom of the well cover body.

Further, when the well cover body is flush with the upper surface of the well frame, the bearing part supports the periphery of the bottom of the well cover body.

Preferably, the connection part is in the shape of a hole or a groove.

According to a specific implementation and a preferred aspect of the present invention, there are two connecting parts, and the two connecting parts are arranged symmetrically with respect to the center of the well cover body.

Preferably, the diameter of the connecting part is 1/20 of the diameter of the well cover body.

Due to the implementation of the above technical solutions, the utility model has the following advantages compared with the prior art:

The utility model prevents the well cover body from loosening relative to the well frame through the screw connection of the well frame and the well cover body, prolongs the service life of the inspection well cover, and at the same time has simple structure, convenient implementation and low cost.

Description of drawings

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail.

Fig. 1 is a cross-sectional schematic diagram of a manhole cover according to the utility model;

Among them: 1. Well frame; 10. Bearing part; 2. Well cover body; 3. Internal thread; 4. External thread; 5. Connecting part.

detailed description

As shown in Figure 1, according to the circular anti-loosening inspection well cover for road engineering of this embodiment, it includes a well frame 1 that can be fixed at the mouth of the inspection well, and a well cover body 2 for closing the opening of the well frame 1 , wherein the opening of the well frame 1 extends in a cylindrical shape along the depth direction of the inspection well, and the shape of the well cover body 2 matches the opening.

In this example, in order to facilitate the stable connection of the well cover body 2 and the well frame 1, the above-mentioned inspection well cover also includes an internal thread 3 and an external thread 4 that are respectively arranged on the inner wall of the opening and the periphery of the well cover body 2, and is arranged on the well cover body 2 to facilitate the connection with the well cover body 2. The connection part 5 where the joints of the tightening tool are connected, wherein the internal thread 3 and the external thread 4 are threadedly connected.

The well frame 1 also includes a bearing part 10 located at the bottom of the opening. When the well cover body 2 is flush with the upper surface of the well frame 1 , the bearing part 10 supports the bottom of the well cover body 2 .

Specifically, when the well cover body 2 is flush with the upper surface of the well frame 1 , the carrying portion 10 supports the periphery of the bottom of the well cover body 2 .

In addition, the arrangement of the connecting portion 5 in this application is very convenient for the installation of the well cover body 2 and the well frame 1 . Specifically, the connecting portion 5 is in the shape of a hole or a groove.

There are two connecting parts 5 , and the two connecting parts 5 are arranged symmetrically about the center of the well cover body 2 .

The diameter of the connecting portion 5 is 1/20 of the diameter of the well cover body 2 .

The utility model has been described in detail above, its purpose is to allow those familiar with the technology in this field to understand the content of the utility model and implement it, and can not limit the scope of protection of the utility model. All equivalent changes or modifications made in essence shall fall within the protection scope of the present utility model.
