Technical Field

The invention relates to the technical field of bolt connection, in particular to a ratchet type anti-loosening bolt connection structure.

Background

The bolt connection is a connection technology which is most widely applied in actual engineering production, can provide reliable clamping force for equipment, and is convenient to disassemble and maintain. The operational environment of bolted connection structure is generally relatively poor, and the influence of external factors such as vibration, impact, temperature difference change often receives in the time, leads to the decline of bolt clamp force, further makes to produce relative motion, threaded connection inefficacy between the screw thread, has influenced mechanical equipment's normal use, especially in important bolted connection position, and the bolt is not hard up has brought very big potential safety hazard for production safety. In order to solve the problem of bolt loosening, technicians conduct a series of loosening prevention technical researches such as friction loosening prevention, mechanical loosening prevention, destructive loosening prevention and the like, but at present, the measures still have the defects of complex processing technology, high cost, insufficient structure, insufficient loosening prevention effect, poor dynamic balance effect and the like.

Disclosure of Invention

The invention provides a ratchet type anti-loosening bolt connecting structure, which aims to solve the problems of complex processing technology, high cost, insufficient anti-loosening effect and poor dynamic balance effect of the existing bolt anti-loosening.

In order to realize the purpose, the technical scheme is as follows:

A ratchet type anti-loosening bolt connecting structure comprises a washer, a nut and a bolt; wherein: the washer is arranged between the nut and the bolt and used for fixing the position relation of the nut and the bolt.

Among the above-mentioned scheme, a ratchet formula anti-loosening bolted connection structure, including packing ring, nut and bolt, simple structure, it is with low costs, the packing ring can the mutual position of fixed nut and bolt, prevents that bolted connection structure is not hard up.

Preferably, the gasket is provided with a gasket ratchet; the gasket ratchet is arranged on one side of the gasket and used for being matched with the nut to be clamped.

The washer ratchet is used for cooperating the nut among the above-mentioned scheme, prevents that the nut is not hard up.

Preferably, the gasket ratchets are ratchet-shaped grooves which are uniformly distributed from the center of a circle to the outside and have triangular sections.

In the scheme, the gasket ratchets are the ratchet-shaped grooves which are uniformly distributed from the inside to the outside of the circle center of the gasket and have triangular sections, and the continuity of the connection pretightening force is improved by the uniformly distributed gasket ratchets.

Preferably, the gasket is provided with a limiting block; the limiting block is arranged on the inner ring of the washer and used for being matched with the bolt to be clamped.

In the scheme, the limiting block is arranged on the inner ring of the gasket and is used for being matched with the bolt to prevent the gasket from moving left and right.

Preferably, one side of the nut is provided with a nut ratchet, and the nut ratchet is matched with the gasket ratchet for clamping.

In the above scheme, when the nut is in clockwise feeding motion, the inclination angle of the contact surface of the gasket ratchet and the nut ratchet is small, the two components can move relatively to realize tight connection, when the nut is in anticlockwise withdrawing motion, the inclination angle of the contact surface is increased, and the two components cannot move relatively to achieve the purpose of self-locking and anti-loosening.

Preferably, the bolt is provided with the slot in vertical direction, the slot with the stopper is mutually supported and is carried out the joint.

In the above scheme, the limiting block is arranged on the inner ring of the gasket, the bolt is provided with the groove in the vertical direction, and the limiting block and the groove are matched with each other to prevent the gasket from moving left and right.

In the scheme, the bolt is provided with the groove and the limiting block capable of accommodating the gasket, and the gasket is fixed in such a way that the gasket cannot rotate left and right; the contact surfaces of the washer and the nut are provided with ratchet structures which have the same size and can be mutually matched, the ratchet structures are similar to crown wheels of the bevel gear on the axial side, and the normal section of the ratchet structures is similar to gear teeth of the ratchet; the gasket ratchets are ratchet-shaped grooves which are uniformly distributed from the inside to the outside of the circle center and have triangular sections, and the continuity of the connection pretightening force is improved due to the uniformly distributed gasket ratchets; in the aspect of mutual motion control, when the nut performs clockwise feeding motion, the inclination angle of the contact surface of the washer and the nut is small, the two components can perform relative motion to realize tight connection, and when the nut performs counterclockwise withdrawing motion, the inclination angle of the contact surface of the two components is large, the two components cannot perform relative motion, so that the purposes of self locking and looseness prevention are achieved.

compared with the prior art, the invention has the beneficial effects that:

The invention provides a ratchet type anti-loosening bolt connecting structure, when a nut performs clockwise feeding motion, the inclination angle of the contact surface of a gasket and the nut is small, two components can perform relative motion to realize tight connection, when performing anticlockwise withdrawing motion, the inclination angle of the contact surface of the two components is large, and the two components cannot perform relative motion, so that the purposes of self locking and loosening prevention are achieved, and the dynamic balance effect is good; the ratchet type anti-loosening bolt connecting structure is improved on the basis of the existing bolt and nut, is convenient to process, mature in technology and low in process cost; the device is detachable and can be repeatedly used.
