Description

Eccentric lever locknut

Technical Field

The utility model relates to the technical field of eccentric nuts, in particular to an eccentric lever type locknut.

Background

The prior application number is CN201620960290.9, which discloses an eccentric lever type locknut, and relates to a nut, wherein the nut comprises an upper end face of the nut, a lower end face of the nut and a threaded hole, and the plane of the upper end face of the nut is mutually perpendicular to the central axis of the threaded hole; the lower end surface plane of the nut is axially spaced from the upper end surface plane of the nut along the threaded hole; the plane of the lower end surface of the nut and the plane of the upper end surface of the nut form an included angle of more than 0 degrees and less than 5 degrees; the center shaft of the threaded hole is not coincident with the centroid of the upper end face of the nut; the center axis of the threaded hole is close to one side with the minimum thickness of the nut; the threaded hole penetrates through the upper end face and the lower end face of the nut; a fillet is arranged on the lower end surface of the nut along the edge line of the threaded hole which is radially far away from the threaded hole; the upper end surface of the nut is provided with a plurality of tightening threaded holes penetrating to the lower end surface of the nut at one side far away from the threaded holes in the radial direction; the beneficial effects are that: reasonable structure, reliable connection, good anti-loose effect, convenient assembly and disassembly and low cost.

The prior art has the following defects: the eccentric lever type locknut has the advantages of reliable connection, good locking effect, convenient assembly and disassembly and low cost, but the concrete principle structure is that the lower end surface plane of the nut and the upper end surface plane of the nut are inclined at an angle of more than 0 DEG and less than 5 DEG, so that the bolt can be bent by breaking the bolt after the nut is screwed down, the axle center of the bolt is changed, the locking effect on the bolt is achieved, the bolt can be used for the second time due to the design, the original structure of the whole bolt can be damaged after the bolt is broken, particularly the thread teeth of the bolt can be mutually extruded to deform each other after the bolt is broken, when the bolt is taken down for the second time, the deformed thread teeth can not be continuously hinged with the thread teeth in the nut, the bolt can not be used for the second time, and the bolt is made into a disposable article.

Therefore, it is necessary to invent an eccentric lever type locknut.

Disclosure of Invention

Therefore, the utility model provides the eccentric lever type locknut, the angle of the clamping groove for clamping the eccentric screw is downwards adjusted to 10 degrees by improving the traditional eccentric lever type locknut, so that a ball at the top of the eccentric screw is inserted into a groove, the eccentric screw is rotated, a connecting block is clamped with the clamping groove, the angle of the clamping groove enables the connecting block not to move due to vibration, the bolt is not damaged, the bolt is clamped, and the locking effect is achieved on the bolt, so that the problem that deformed thread teeth in the background art cannot be continuously hinged with the thread teeth in the nut, the bolt cannot be used for the second time, and the bolt becomes a disposable article is solved.

In order to achieve the above object, the present utility model provides the following technical solutions: the utility model provides an eccentric lever locknut, includes eccentric nut and eccentric screw rod, the recess is seted up to eccentric nut bottom, its characterized in that: and the right side of the groove is provided with a clamping groove by the eccentric nut.

Preferably, the eccentric nut is cylindrical in shape, a bolt is fixedly arranged at the bottom of the eccentric screw, and a rotating groove is formed in the top of the eccentric nut.

Preferably, a connecting block is fixedly arranged at the top of the eccentric screw, and a clamping ball is fixedly arranged at the top of the connecting block.

Preferably, the shape of the clamping ball is a sphere, the shape of the eccentric screw is a cylinder, and the shape of the connecting block is also a cylinder.

The beneficial effects of the utility model are as follows: through improving traditional eccentric lever nut, with original block groove angle downward adjustment to 10 degrees that are used for block eccentric screw, insert the recess with the ball at eccentric screw top like this, rotate eccentric nut, connecting block and block groove block, the angle in block groove makes the connecting block can not remove because of vibrations, neither can harm the bolt like this, also realizes block bolt, plays an locking effect to the bolt.

Detailed Description

The preferred embodiments of the present utility model will be described below with reference to the accompanying drawings, it being understood that the preferred embodiments described herein are for illustration and explanation of the present utility model only, and are not intended to limit the present utility model.

Referring to fig. 1-5, the utility model provides an eccentric lever type locknut, and in order to achieve the above purpose, the utility model provides the following technical scheme: the utility model provides an eccentric lever locknut, includes eccentric nut 1 and eccentric screw rod 2, and recess 3, its characterized in that are seted up to eccentric nut 1 bottom: the eccentric nut 1 is provided with the clamping groove 4 on the right side of the groove 3, the angle of the clamping groove 4 is offset to the bottom of the eccentric nut 1 by 10 degrees, the eccentric nut 1 can be inserted into the eccentric nut 1 by providing the groove 3, after the clamping ball 6 is inserted into the eccentric nut 1 by opening the clamping groove 4, the connecting block 7 can slide into the clamping groove 4 by rotating the eccentric nut 1, so that the eccentric nut 1 is clamped with the eccentric screw 2 and is tightened, and meanwhile, the connecting block 7 cannot move towards the groove even if being vibrated due to the angle of the clamping groove 4.

Further, the eccentric nut 1 is cylindrical in shape, a bolt 5 is fixedly installed at the bottom of the eccentric screw 2, a rotating groove 8 is formed in the top of the eccentric nut 1, and the surface of other objects to be connected is connected through the bolt 5.
