Description

A kind of subassembly of lock bolt
Technical field
The utility model relates to connector technical field more particularly to a kind of subassembly of lock bolt.
Background technique
Bolt is widely used in the various aspects of life by people as connector.Due to by extraneous and oneself factor Influence, cause bolt to loosen, therefore various check bolts occur.However, most of check bolts are locking It is ineffective, it is unable to reach requirement.
Utility model content
The utility model provides a kind of subassembly of lock bolt, can meet the need of the occasion more demanding to anti-loosing effect It wants.
In order to solve the above technical problems, the technology employed by the present utility model is
A kind of subassembly of lock bolt, including bolt and matched nut;The seal face of bolt is integrally formed with multiple The seal face of first wedge slope of circumferential step arrangement, nut is oblique integrally formed with the third wedge shape of multiple circumferential step arrangements Slope;
It further include having identical first locking sleeve of structure and the second locking sleeve;
First locking sleeve includes the hollow circuit cylinder and annular flange disk of integrated molding and concentric setting;Hollow circuit cylinder One end far from annular flange disk is circumferentially with multiple rectangle gap along it;A side end face one of the flange far from hollow circuit cylinder Body formed the second wedge slope for having multiple circumferential step arrangements;
First locking sleeve and the second locking sleeve are sheathed on bolt and are located at the seal face of bolt and the pressure of nut Between tight face;The hollow circuit cylinder of first locking sleeve and the second locking sleeve is oppositely arranged and can be locked mutually by rectangle gap Limit.
According to above scheme, first wedge slope, the second wedge slope are identical with the structure of third wedge slope, and The inclination angle of first wedge slope, the second wedge slope and third wedge slope is all larger than the lead angle of bolt.
According to above scheme, the adjustable in length of the hollow circuit cylinder of first locking sleeve.
According to above scheme, the width between two adjacent rectangle gap neck side of first locking sleeve is less than rectangle The width of gap itself.
Compared with prior art, the utility model has the beneficial effects that after the utility model is screwed into connected piece, due to The wedge slope of locking sleeve and bolt head and nut bottom is worked in coordination, and locking sleeve is connected to become by rectangle gap One, therefore, when bolt pine moves back, the wedge slope of locking sleeve can prevent it;And due to the inclination of wedge slope Angle is greater than the lead angle of bolt, therefore even if under vibrating conditions, the pine of bolt, which moves back, can also be prevented from, so that it is anti-to enhance bolt The effect of pine.

Fig. 2 is the fractionation structural representation of the utility model;
Fig. 3 is the structural schematic diagram of bolt in the utility model;
Fig. 4 is the positive structure diagram of the first locking sleeve in the utility model;
Fig. 5 is the schematic perspective view of the first locking sleeve in the utility model;
Fig. 6 is the structural schematic diagram of nut in the utility model.
Specific embodiment
Specific embodiment of the present utility model is described further with reference to the accompanying drawing, the paraphrase of each label in figure Are as follows: bolt 1, the first locking sleeve 2, the second locking sleeve 3, nut 4, rectangle gap 21, the first wedge slope 11, the second wedge shape Slope 22, third wedge slope 41.
The utility model includes bolt 1, the first locking sleeve 2, the second locking sleeve 3 and nut 4.
The seal face of the bolt 1 is provided with the first wedge slope 11, circumferentially ladder-like distribution.
First locking sleeve 2 is identical with the structure of the second locking sleeve 3.
First locking sleeve 2 includes the hollow circuit cylinder and annular flange disk of integrated molding and concentric setting.Hollow circle The one end of column far from annular flange disk is circumferentially with multiple rectangle gap 21 along it;A side of the flange far from hollow circuit cylinder Second wedge slope 22 of the face integrally formed with multiple circumferential step arrangements.
First locking sleeve 2 and the second locking sleeve 3 are sheathed on the seal face and nut 4 on bolt 1 and being located at bolt 1 Seal face between.
First locking sleeve 2 is mounted on bolt 1, makes the first wedge slope 11 and the first locking sleeve 2 of bolt 1 On the second wedge slope 22 cooperate.
The hollow circuit cylinder of first locking sleeve 2 and the second locking sleeve 3 is oppositely arranged and can be mutual by rectangle gap 21 Locking limit, so that the second locking sleeve 3 can not be rotated relative to bolt 1 and the first locking sleeve 2.
The nut 4 is equipped with third wedge slope 41, the third wedge slope 41 of nut 4 and the second locking sleeve 3 Second wedge slope 22 matches so that nut 4 and the second locking sleeve 3 can not relative rotation, finally, so that nut 4 and spiral shell The relative position of bolt 1 is fixed.
Further, the inclined angle alpha of first wedge slope 11, the second wedge slope 22 and third wedge slope 41 is wanted Slightly larger than the lead angle of bolt 1, so that two adjacent components are tightly bited into an entirety, when there is vibration to occur, The mutual changing of the relative positions of the convex portion of wedge slope generates lifting tension, to reach perfect anti-loosing effect.
Further, the length of fit of the first locking sleeve 2 and the second locking sleeve 3 should be variable, so that it is installed Range increases.
Further, the width between two 21 adjacent sides of rectangle gap should not exceed the width of rectangle gap 21 itself with suitable In grafting.
The implementation steps of the utility model are as follows:
First locking sleeve 2 is mounted on bolt 1, when installation, the first wedge slope 11 and the first lock of bolt 1 should be made Second wedge slope 22 of fixed cylinder 2 matches;
Bolt 1 and the first locking sleeve 2 are inserted into connecting component;
Second locking sleeve 3 is mounted on bolt 1, when installation, 21 He of rectangle gap of the first locking sleeve 2 should be made The rectangle gap 21 of second locking sleeve 3, which cooperates, to be inserted into;
Nut 4 is screwed in into bolt 1, nut 4 is tightened to and made the third wedge slope 41 and the second locking sleeve of nut 4 3 the second wedge slope 22 cooperation, and make the torque of nut 4 in the torque range of design.
