Abstract

The utility model discloses a lock nut, the body of the lock nut is provided with a polygonal flange used for rotationally screwing. The inner part of the body is provided with a screwed hole with screw threads, a pin hole which passes through the body and is communicated with the screwed hole is arranged above the flange of the body, and the outer part of the pin hole of the body is provided with an annular groove; a pin is arranged in the pin hole, a snap spring is arranged in the annular groove, and the outer end of the pin is blocked by the snap spring. The lock nut has the advantages of simple structure and simple processing art. Because the lock nut has good lock effect, the lock nut can be made from general material to reduce manufacture cost. The lock parts of the lock nut can be disassembled, so the lock nut can be recycled to save sources and enhance the integral performance of products.

Description

A kind of anti-loosening nut
Technical field
The utility model relates to fastening piece, relates in particular to a kind of anti-loosening nut.
Background technique
All have vibration to produce during the big machinery machine works, this not only consumes a part of power, the waste energy, vibration simultaneously can cause that also each connected element produces loosening phenomenon, especially at the position that nut bolt connects, just have the possibility that comes off, cause accident to produce in case nut loosening occurs.For breaking away from the influence of vibration in the nut bolt joint, prior art is produced has nut anti-loosening when mechanical vibration, and the helical teeth of the employing barb shape that has can not prolong loosening direction rotation again at the connection back nut; The employing spiral groove and the ball that have, at the Chinese patent publication number be CN2584917 patent disclosure a kind of fastening piece, internal thread at nut body directly upwards is provided with groove, one end of groove is a deep end, the other end is a shallow end, and its degree of depth is gradual change type, is furnished with ball mutually with groove, the depth dimensions than deep end of the diameter dimension of ball and groove matches, and can not prolong loosening direction rotation again at the connection back nut equally; Contact stress increasing that the employing nut distortion back that has produces and the frictional force between the bolt can not be prolonged loosening direction rotation again at the connection back nut too.Though it is loosening that these anti-loosening technology guarantee that nut is difficult for, when replacing parts dismounting nut, can only do destructive dismounting, therefore such nut is non-exchange after in a single day installing, and can not reuse; Simultaneously all be to be based upon under the situation of nut generation deformation to realize anti-loosening purpose when utilizing helical teeth and increase the method for contact stress, this just requires nut should possess higher mechanical strength, thereby when producing, select the comparatively expensive metal of price, the cost of production height, and structurally, nut also should possess deformable labyrinth, makes the production and processing complexity, the required precision height.
The model utility content
The technical problems to be solved in the utility model provides a kind of anti-loosening nut, low production cost, and processing technology is simple, can reuse.
For solving the problems of the technologies described above, the utility model adopts following technological scheme: this anti-loosening nut body is provided with the flange of the regular polygon that is used to screw, be provided with a tapped screw in described body interior, described body is provided with a pinhole that crosses body and be communicated with screw above flange, described body is provided with annular groove in the outside of pinhole position, in described pinhole, be provided with pin, be provided with jump ring in the described annular groove, the outside end of described pin is blocked by described jump ring.
The utility model adopts technique scheme, and anti-loosening nut structure is simple, simplified processing process; Owing to still have good anti-loosening effect, make it can adopt general raw material, reach the purpose that reduces production costs; Anti-loosening nut plays anti-loosening part detachable, therefore makes anti-loosening nut to reuse, and economizes on resources, and promotes the product overall performance.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described further.
Fig. 1 is the structural representation of a kind of anti-loosening nut of the utility model.
Embodiment
As shown in Figure 1, this anti-loosening nut body is provided with the flange 1 of the regular polygon that is used to screw, be provided with a tapped screw 2 in this body interior, body is provided with a pinhole 3 that crosses body and be communicated with screw 2 above flange 1, therefore pinhole 3 is distributed in screw 2 both sides, and body is provided with annular groove 4 in the outside of pinhole 3 positions, is provided with pin 5 in the pinhole 3, be provided with jump ring 6 in the annular groove 4, pin 5 outside ends are blocked by described jump ring 6.During use, anti-loosening nut body is installed pin 5 after being screwed in bolt again in pinhole 3, be used in the jump ring 6 of packing in the annular groove 4 then, makes pin 5 tightly block bolt.By the position of pin 5 further set screw nuts, play anti-loosening purpose.

Claims (1)

1, a kind of anti-loosening nut, this anti-loosening nut body is provided with the flange (1) of the regular polygon that is used to screw, be provided with a tapped screw (2) in described body interior, it is characterized in that: described body is provided with a pinhole (3) that crosses body and be communicated with screw (2) in the top of flange (1), described body is provided with annular groove (4) in the outside of pinhole (3) position, in described pinhole (3), be provided with pin (5), be provided with jump ring (6) in the described annular groove (4), the outside end of described pin (5) is blocked by described jump ring (6).
