Background art:

the existing common nodular cast iron well lid is simple in structure, generally, the well lid directly covers the upper edge of a well body, is easy to break in the using process, has noise under the action of external force, is inflexible to open and close, is poor in durability, is easy to lose and is poor in safety.

The utility model has the following contents:

the utility model aims at overcoming the defects of the prior art and providing the multipurpose nodular cast iron well lid.

The utility model provides a technical scheme is: the multipurpose nodular cast iron well lid consists of a lid body and an upper lid, and is characterized in that the upper lid is provided with two outer hinge seats; the cover body is provided with two inner spring seats, a spring is arranged between the two inner spring seats, the hinge shaft penetrates through the two inner spring seats and the spring in the middle, two ends of the hinge shaft are respectively inserted into two outer hinge seats adjacent to the outer sides of the two inner spring seats, and the cover body and the upper cover are connected through a one-way spring hinge; the inner side of the cover body is provided with a spring lock tongue groove, a spring lock and a key hole are arranged at the corresponding position of the upper cover, after the spring lock is clamped with the spring lock tongue groove, the upper cover and the cover body are locked, a key is inserted into the key hole, the upper cover can be bounced and opened from the cover body through rotation, and the angle between the upper cover and the cover body after the upper cover and the cover body are opened is an oblique angle of 100 degrees and 105 degrees; a special-shaped groove is formed at the seam allowance of the cover body, and a special-shaped rubber ring is embedded in the special-shaped groove; the surface of the upper cover is provided with raised patterns.

Furthermore, the middle of the upper cover is bulged, and the bulging height is 0.2-0.3% of the diameter of the upper cover.

The utility model has the advantages that: 1. a special-shaped groove is formed in the seam allowance of the cover body, a special-shaped rubber ring is embedded into the special-shaped groove, and the special-shaped groove plays a role in damping under the action of external force or when a vehicle passes through the special-shaped groove and is noiseless; 2. the spring lock is arranged on the upper cover, and the cover body is provided with a spring bolt groove which is locked when closed, so that the anti-theft effect can be achieved; the lock is opened by a key, so that the lock is safe and reliable; 3. the surface of the upper cover adopts convex patterns, so that a good anti-skid effect can be achieved; 4. the cover body and the upper cover are tightly combined, so that the phenomena of jumping, lifting, sounding, shifting and the like are avoided, and the safety and the reliability are realized; 5. the middle of the upper cover is slightly bulged, and the well cover cannot be sunken and is not easy to deform and break under the action of external force; 6. the upper cover is opened from the cover body, and after the upper cover is opened, the angle between the upper cover and the cover body is 100 degrees and 105 degrees, so that the upper cover is completely opened, the operation is convenient, and the labor is saved in closing; 7. the manhole cover has the advantages of convenience in use, time saving, avoidance of the occurrence of the fracture phenomenon of the manhole cover, material saving and improvement of economic benefits.

Description of the drawings:

fig. 1 is a schematic structural diagram of the present invention.

In the figure: the lock comprises a cover body 1, an upper cover 2, an inner spring seat 3, a latch 4, a latch tongue groove 5, a special-shaped rubber ring 6, a special-shaped groove 7, a key 8, a spring 9, an outer hinge seat 10 and a hinge shaft 11.

The specific implementation mode is as follows:

for a better understanding and practice, the following detailed description of the embodiments is given in conjunction with the accompanying drawings; the examples are given solely for the purpose of illustration and are not intended to limit the scope of the invention.

As shown in fig. 1, the multipurpose nodular cast iron manhole cover is made of nodular cast iron, has the specification size of 400-14000 cm, and can also be determined according to the requirements of municipal infrastructure; the well lid consists of a lid body 1 and an upper lid 2, wherein raised patterns are processed on the surface of the upper lid 2, the middle of the upper lid 2 bulges, and the bulging height is 0.2-0.3% of the diameter of the upper lid 2; a special-shaped groove 7 is formed in the seam allowance of the cover body 1, and a special-shaped rubber ring 6 is embedded in the special-shaped groove 7; two outer hinge seats 10 are arranged on the upper cover 2, two inner spring seats 3 are arranged on the cover body 1, a spring 9 is arranged between the two inner spring seats 3, a hinge shaft 11 penetrates through the two inner spring seats 3 and the spring 9 in the middle, and two ends of the hinge shaft are respectively inserted into the two outer hinge seats 10 which are adjacent to the outer sides of the two inner spring seats 3, so that a one-way spring hinge connection is formed between the cover body 1 and the upper cover 2, namely the upper cover 2 is a spring hinge structure which can only be opened in one way; the inner side of the cover body 1 at the corresponding position of the one-way spring hinge connection is provided with a spring bolt groove 5, the upper cover 2 is provided with a spring bolt 4 at the corresponding position, and is provided with a key hole 8, after the spring bolt 4 is clamped with the spring bolt groove 5, the upper cover 2 is locked with the cover body 1, a key is inserted into the key hole 8, the upper cover 2 can be bounced up and opened from the cover body 1 through rotation, and the angle between the upper cover 2 and the cover body is an oblique angle of 105 degrees after the upper cover 2 is opened.
