Description

The lock nut pad is inlayed combination set
Technical field
The present invention relates to a kind of lock nut pad and inlay combination set.
Background technique
Regular screw threads fastening piece locking mode commonly used mainly contains the frictional force that improves between the screw pair, directly pins, adopts modes such as dashing point to destroy screw thread kinematic pair relation etc. with retainer.Retainer locking is subjected to restrictions such as connected piece shape, size, restricted application.Be fit to be applied to need not to dismantle occasion towards modes such as points.The locking mode that most Fastener products adopt is unreasonable, and like spring washer etc., its anti-loosening property improves and is not cost with the worm tooth axial tension, causes the fatigue strength of bolt to reduce easily.Publication number is that the Chinese patent of CN 101338777 discloses a kind of anti-loosening nut and the method for making this nut; 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 said body interior; Said body is provided with a pinhole that crosses body and be communicated with screw above flange; Said body is provided with annular groove in the outside of pinhole position; In said pinhole, be provided with pin; Be provided with jump ring in the said annular groove, the outside end of said pin is blocked by said jump ring.This structure guarantees that nut is loosening under the low-load situation, but owing to nut vertically being cut and having the pin-and-hole that crosses nut body, has reduced nut strength that pin is prone to make the bolt thread distortion simultaneously, can't guarantee to be repeatedly used.
Summary of the invention
Technical problem to be solved by this invention provides a kind of reasonable in design, simple, and anti-loosing effect is good, and screw thread is not damaged, long service life, and reliable and stable lock nut pad is inlayed combination set.
It is that this lock nut pad is inlayed combination set that the present invention solves the problems of the technologies described above the technological scheme that is adopted; Comprise nut body; Its structural feature is: also be provided with the packing ring body; Described packing ring body is provided with the flange embedded body; Said nut body is provided with nut groove and axially stretches out body; Said flange embedded body is embedded among the nut groove, and said packing ring body is wrapped in axially and stretches out on the body.
As preferably, the height of flange embedded body of the present invention is greater than the degree of depth of nut groove, and the thickness of flange embedded body is less than the width of nut groove.
As preferably, the height that axially stretches out body of the present invention equals the thickness of packing ring body, and the internal diameter of outside diameter and packing ring body that axially stretches out body is suitable.
As preferably, the height that axially stretches out body of the present invention is 2 to 5 times of pitch, and thickness is 2 to 3 times of pitch.To improve the deformation direction of flange embedded body, improve the secondary frictional force that is threaded.
As preferably, the degree of depth of nut groove of the present invention is 2 to 3 times of pitch.
As preferably, a kind of in the triangle that it is circular arc that nut groove of the present invention is shaped as rectangle, trapezoidal, long limit.To improve the deformation direction of flange embedded body, improve the secondary frictional force that is threaded.
As preferably, the flange embedded body hand of spiral of the present invention cross section is a kind of in the triangle that is circular arc of rectangle, trapezoidal, long limit.To improve of the vertical extruding of packing ring body to nut inner thread.
As preferably, the body diametric(al) of axially stretching out of the present invention is provided with 2 to 4 pairs and stretches out the narrow groove of body, and said flange embedded body diametric(al) is symmetrically arranged with 2 to 4 pairs of narrow grooves of embedded body.Increased the elasticity of axially stretching out body, improve with internal thread between cooperate tightness.Improve elastomeric deformability, improve the nut disassembling section.
The present invention compares with prior art and has the following advantages and effect: this structure produces resiliently deformable through flange embedded body pressurized; Improve the axial force of nuts and bolt; Can improve the frictional force between the screw pair; Frictional force between flange embedded body and nut body has the locking effect; Simultaneously, flange embedded body compressive deformation has squeezing action to nut body in the vertical axial plane; Change the relation of screw thread kinematic pair and do not injured screw thread, improved anti-loosening property.

Embodiment
Below in conjunction with embodiment the present invention is done further detailed description, following examples are to explanation of the present invention and the present invention is not limited to following examples.
Embodiment 1:
Shown in Fig. 1 to 6, present embodiment by nut body 1, packing ring body 2, axially stretch out body 5, flange embedded body 6 is formed.Wherein, the inside of nut body 1 is provided with internal thread 3.Nut body 1 is provided with and axially stretches out body 5, is provided with nut groove 4 on the next door of axially stretching out body 5.Packing ring body 2 is provided with flange embedded body 6, and flange embedded body 6 is embedded in the nut groove 4, and the height of flange embedded body 6 is greater than the degree of depth of nut groove 4, and the thickness of flange embedded body 6 is less than the width of nut groove 4.The height that axially stretches out body 5 equals the thickness of packing ring body 2, and the outside diameter that axially stretches out body 5 is suitable with packing ring body 2 internal diameters.
Axially stretch out body 5 diametric(al)s and be provided with 2 pairs and stretch out the narrow groove 7 of body, flange embedded body 6 diametric(al)s are symmetrically arranged with 2 pairs of narrow grooves 8 of embedded body.
When tightening; Bolt is screwed into nut body 1; Flange embedded body 6 pressurizeds produce resiliently deformable, improve the axial force of nut body 1 and bolt, can improve the frictional force between the screw pair; The frictional force that flange embedded body 6 and nut body are 1 has the locking effect; Simultaneously, flange embedded body 6 compressive deformations have squeezing action to nut body 1 in the vertical axial plane; Change the relation of screw thread kinematic pair and do not injured screw thread, improved anti-loosening property.
