Abstract
The invention relates to a locknut shim insert combination external member which comprises a nut body. The external member is structurally characterized by also being provided with a gasket body, wherein the gasket body is provided with a flange insetting body; the nut body is provided with a nut groove and an axial protruding body; the flange insetting body is embedded in the nut groove; and the gasket body is covered on the axial protruding body. The external member provided by the invention has the advantages of reasonable and simple structure design, good anti-loosing effect, long service life, safety and reliability; and the thread is free from being damaged.
Description
Technical field
The present invention relates to a kind of locknut shim insert combination external member.
Background technique
Regular screw threads fastening piece locking mode commonly used mainly contains the frictional force that improves between the screw pair, directly pin, adopt the mode such as punching point to destroy screw thread kinematic pair relation etc. with retainer.Retainer locking is subjected to the restrictions such as connected piece shape, size, restricted application.The modes such as punching point are fit to be applied to need not to dismantle occasion.The locking mode that most Fastener products adopt is unreasonable, and such as spring washer etc., its anti-loosening property improves and is not cost with the worm tooth axial tension, causes easily the fatigue strength of bolt to reduce.Publication number is the method that the Chinese patent of CN 101338777 discloses a kind of Anti-loosening nut and this nut of manufacturing, this Anti-loosening nut body is provided with the flange be used to the regular polygon of screwing, 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.This structure guarantee that nut is loosening in the low-load situation, but owing to nut vertically being cut and with the pin-and-hole that crosses nut body, having reduced nut strength, pin easily makes 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, reliable and stable locknut shim insert combination external member.
It is this locknut shim insert combination external member that the present invention solves the problems of the technologies described above the technological scheme that adopts, comprise nut body, its structural feature is: also be provided with the packing ring body, be provided with the flange embedded body on the described packing ring body, be provided with nut groove on the described nut body and axially stretch out body, described flange embedded body is embedded among the nut groove, and described 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 that axially stretches out the outside diameter of body and packing ring 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 frictional force of threaded connection pair.
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 frictional force of threaded connection pair.
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 the packing ring body to vertical extruding of 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 described 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 dismounting operation.
The present invention compares with prior art and has the following advantages and effect: this structure produces resiliently deformable by 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
The present invention is described in further detail below in conjunction with embodiment, and following examples are explanation of the 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 forms.Wherein, the inside of nut body 1 is provided with internal thread 3.Be provided with on the nut body 1 and axially stretch out body 5, be provided with nut groove 4 on the next door of axially stretching out body 5.Be provided with flange embedded body 6 at packing ring body 2, 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.
