Description

Technical Field

[0001] The utility model relates to the technical field of cast iron supports, in particular to an anti-theft and noise-reducing cast iron support. Background Art

[0002] At present, most of the manhole cover supports on the market are made of cast iron, steel and other materials, such as cement, resin, etc. Manhole cover supports of different materials have different advantages and disadvantages, and need to be selected according to the specific use environment and requirements. The implementation of its technical solutions is mainly aimed at the problems existing in different applicable environments, and relevant technical research is carried out, such as the research and development of new materials and the introduction of new processes. Urban roads are one of the main areas of application of manhole covers and supports, including streets, sidewalks, squares and other places.

[0003] The function of existing manhole covers is usually to protect pedestrians from stepping on empty space and filter sewage. Although it is convenient to use, it still has obvious defects in actual use, such as:

[0004] 1. Because the material of the manhole cover is light or the lock has safety hazards, there is a risk of the manhole cover being stolen;

[0005] 2. Manhole covers and supports generate noise when vehicles and pedestrians pass through, affecting the surrounding areas.

[0006] Therefore, anti-theft and noise-reducing cast iron supports are now designed to solve such defects. Utility Model Content

[0007] In view of the deficiencies in the prior art, the utility model provides an anti-theft and noise-reducing cast iron support, which solves the problem that the existing manhole covers are easily stolen and have noise.

[0008] To achieve the above objectives, the utility model is implemented through the following technical solutions: an anti-theft and noise-reducing cast iron support, including a manhole cover support, wherein the edge side of the inner rear side of the manhole cover support is threadedly connected with bolt parts through an opening, and the bolt parts are grouped into four and are arranged in a ring-shaped and equidistant manner.

[0009] Preferably, a rubber air spring is fixedly connected to the rear portion of the inner side of the manhole cover support, and the rubber air spring is located between two adjacent groups of bolt members.

[0010] Preferably, a rubber ring is fixed to the inner side wall of the manhole cover support, and the rubber ring is located between two adjacent groups of bolt members. Beneficial Effects

[0011] The utility model provides an anti-theft and noise-reducing cast iron support. Compared with the existing technology, it has the following beneficial effects:

[0012] (1) The anti-theft and noise-reducing cast iron support is provided by installing a plurality of groups of bolts on the inner side of the manhole cover support and connecting them by opening an opening. This structural setting can fix the manhole cover by utilizing the special-shaped function of the bolts, and after fixation, it cannot be disassembled by using common tools in life, so the safety and anti-theft function of the manhole cover are effectively improved, which satisfies the current use.

[0013] (2) The anti-theft and noise-reducing cast iron support has a rubber air spring and a rubber ring installed on the inner side of the manhole cover support. The arrangement of these structures can utilize the rubber air spring and the rubber ring to block the manhole cover and the manhole cover support. When subjected to pressure, it can effectively reduce shock and noise, reduce the impact on the surrounding environment, and improve the overall practicality. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] See also Figure 1-4 The utility model provides a technical solution: an anti-theft and noise-reducing cast iron support, including a manhole cover support 1, the edge side of the inner rear side of the manhole cover support 1 is threadedly connected with a bolt member 2 through an opening, and the bolt members 2 are grouped into four and are arranged in a ring-shaped and equidistant manner. The safety of the manhole cover is improved by increasing the number of bolt members 2 and using special-shaped heads.

[0021] A rubber air spring 3 is fixedly connected to the rear of the inner side of the manhole cover support 1. The rubber air spring 3 mainly uses a rubber part as a closed container. As the load of the spring increases, the compressed air pressure in the container increases, so that the spring stiffness also increases. As the load decreases, the spring stiffness also decreases as the air pressure decreases. It has an ideal variable stiffness elastic characteristic. The elastic characteristics of the rubber material itself can reduce shock and noise. The rubber air spring 3 is located between two adjacent groups of bolts 2. A rubber ring 4 is fixed to the side wall of the inner side of the manhole cover support 1, and the rubber ring 4 is located between two adjacent groups of bolts 2.

[0022] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0023] Before use, the manhole cover is installed on the inner side of the manhole cover support 1 using several groups of bolts 2, and the bottom and edge of the manhole cover are respectively fitted with the rubber air spring 3 and the rubber ring 4. During daily use, the bolts 2 are special-shaped parts and cannot be disassembled by common tools, which improves the safety and anti-theft performance of the manhole cover. At the same time, when the manhole cover is under pressure, the pressure is transmitted to the rubber air spring 3, causing the internal air pressure of the rubber air spring 3 to increase, and the stiffness of the spring is increased to play a shock-absorbing role. At the same time, the outside of the rubber air spring 3 itself and the rubber ring 4 are made of rubber, thereby reducing the noise generated during impact.
