Abstract
The utility model discloses a large-diameter bolt which comprises a tip and a screw, wherein the tip is fixed with the screw, first threads are arranged inside the tip, second threads are arranged at the bottom end of the screw, and the diameter of the screw is from 50cm to 100cm. The large-diameter bolt is simple in structure, reduces cost and is not prone to loosening.
Description
Technical field
The utility model relates to a kind of bolt, particularly relates to a kind of large diameter bolt.
Background technique
Along with industrial expansions such as China's chemical industry, refining are taken out, electric power, main equipment and high-pressure bottle are more and more, and the diameter of bolt is also increasing.The complex structure of present large diameter bolt, the cost height, easily loosening.
The model utility content
Technical problem to be solved in the utility model provides a kind of large diameter bolt, and it is simple in structure, reduces cost, and is difficult for loosening.
The utility model solves above-mentioned technical problem by following technical proposals: a kind of large diameter bolt, it is characterized in that, it comprises termination and screw rod, termination and screw rod are fixed, the inside of termination is provided with first screw thread, the bottom of screw rod is provided with second screw thread, and the diameter of screw rod is 50 centimetres to 100 centimetres.
Preferably, the diameter of described screw rod is 80 centimetres.
Preferably, be with a pad on the described screw rod, the diameter of pad is 80 centimetres to 140 centimetres.
Preferably, the diameter of described pad is 120 centimetres.
Positive progressive effect of the present utility model is: the utility model large diameter bolt simple in structure, reduce cost, and be difficult for loosening.
Description of drawings
Fig. 1 is the structural representation of the utility model large diameter bolt.
Embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.
As shown in Figure 1, the utility model large diameter bolt comprises termination 1 and screw rod 2, and termination 1 is fixing with screw rod 2, the inside of termination 1 is provided with first screw thread 4, the bottom of screw rod 2 is provided with second screw thread 3, and the diameter of screw rod 2 can be 50 centimetres to 100 centimetres, is preferably 80 centimetres.Can be with a pad 5 on the screw rod 2, the diameter of pad is 80 centimetres to 140 centimetres, is preferably 120 centimetres.
The working principle of the utility model large diameter bolt is as follows: screw rod is connected with an element, and second screw thread can be threaded with this element, and such second screw thread can prevent becoming flexible between screw thread and this element.Pad can further prevent becoming flexible between screw thread and this element.The utility model large diameter bolt simple in structure reduces cost, and is difficult for loosening.
Those skilled in the art can carry out various remodeling and change to the utility model.Therefore, the utility model has covered various remodeling and the change in the scope that falls into appending claims and equivalent thereof.
