Abstract
The utility model discloses a U-shaped bolt with a check nut, comprising a U-shaped bolt, wherein two ends of the U-shaped bolt are both provided with a threaded connection section, and the threaded connection section is in threaded connection and provided with a nut which is a check nut. The U-shaped bolt with the check nut has the advantages of being simple in structure and being capable of effectively preventing the nut from loosening.
Description
Technical field
The utility model relates to a kind of fastening piece, specifically is meant a kind of U-bolt that has lock nut.
Background technique
Fastening piece is to be used for connecting between the mechanical part and the fixing indispensable part of device.In the suspension system of existing automobile, tractor and rail truck, extensively use leaf spring, this leaf spring relies on the frictional force between steel plate and the steel plate and has higher buffering and damping property, existing leaf spring, it is fixing that assembly unit between its steel plate and the steel plate all adopts the U-bolt attaching nut to assemble, but, it is loosening on U-bolt that nut in use appears in leaf spring easily, thereby the operational failure of bringing is brought loss to the user.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming and defect that prior art exists, and provides a kind of simple in structure and can effectively prevent the U-bolt that has lock nut of nut loosening.
For achieving the above object, the technical solution of the utility model is to include U-bolt, and the two end part of this U-bolt are provided with the section of being threaded, and is threaded on this section of being threaded to be provided with nut, and described nut is a lock nut.The inner side surface that further setting is described nut is provided with rubbing surface, and described rubbing surface is made up of the cutter type lug of annular spread.
The utility model has the advantages that, the many of leaf spring are serially connected on the U-bolt with steel plate, be fixed on the section of being threaded of U-bolt by nut then, and the side that is positioned at the rubbing surface of nut inner side surface and nut neighbour's steel plate is in contact with one another and presses, because the existence of rubbing surface, and make nut and steel plate be tightly fixed together, can solve becoming flexible between the two very simply.
Below in conjunction with specification drawings and specific embodiments the utility model is done further introduction.
Description of drawings
Fig. 1 the utility model embodiment structural representation;
Fig. 2 the utility model embodiment STRUCTURE DECOMPOSITION figure.
Embodiment
Embodiment of the present utility model shown in Fig. 1-2 includes U-bolt 1, and the two end part of this U-bolt 1 are provided with the section of being threaded 11, is threaded on this section of being threaded 11 to be provided with nut 2, and described nut 2 is a lock nut.This lock nut of the utility model can adopt the lock nut of at present commercially available routine all can, this nut 2 of present embodiment is preferably following setting, the inner side surface of described nut 2 is provided with rubbing surface 21, and described rubbing surface 21 is made up of the cutter type lug 211 of annular spread.
The utility model has the advantages that, the many of leaf spring 1 are serially connected on the U-bolt with steel plate, be fixed on the section of being threaded of U-bolt by nut 2 then, and the side of the rubbing surface 21 that is positioned at nut 2 inner side surfaces and nut 2 neighbours' steel plate is in contact with one another and presses, because the existence of rubbing surface, and make nut and steel plate be tightly fixed together, can solve becoming flexible between the two very simply.
The foregoing description is to specific descriptions of the present utility model; only be used for the utility model is further specified; can not be interpreted as the qualification to the utility model protection domain, the technician of related domain makes some nonessential improvement and adjusts the utility model according to the content of above-mentioned model utility and all falls within the protection domain of the present utility model.
