Abstract

The invention relates to a connecting structure for quickly locking two parts, in particular to a quick locking mechanism. A locking structure combining an oblique plane and a locking thread is adopted, the quick locking of two workpieces to be locked is realized, and the quick locking mechanism is self-locked and anti-loose after being locked. In the quick locking mechanism, a compression spring is mounted under a locking shaft, the locking shaft rotates in the locking process, when the locking force is excessive due to misuse, the compression spring can play the role of preventing a locking nut from being deadly blocked in the screwing process, and the effect of protecting the thread is realized. The axial displacement of the whole quick locking mechanism in the locking process is the superposition of spiral displacement of the locking shaft and the oblique plane rising displacement of an oblique pressing block, and the locking efficiency is greatly improved; in the locking process, the lower surface of the locking nut presses the upper locking oblique plane of the oblique pressing block, with the effect of a spring gasket, the quick locking mechanism is self-locked and anti-loose after being locked; a special tool in the quick locking mechanism can take the effect of dismantling resistance and prevent the dismantling due to misoperation.

Description

A kind of quick-locking mechanism
Technical field
The present invention relates to a kind of linkage structure can carrying out quick locking to two parts, particularly relate to a kind of quick-locking mechanism.
Background technique
Between common two parts, locking is that screw 13, through workpiece 14, is fixed on workpiece 15 by being with the lock screw of regular screw threads to carry out, spring washer is added time locking, but this locking mode, after repeatedly repeating locking, there will be thread damage, affect locking function; And this locking mode is owing to only leaning on screw lock, and locking efficiency is low.
Summary of the invention
Not the object of this invention is to provide a kind of screw thread fragile and lock the high quick-locking mechanism of efficiency.
Technical solution of the present invention is, locking mechanism comprises lock sleeve 2, lock shaft 3, locking nut 4, briquetting 5, inner nut 7, spring washer 8, Compress Spring 9, baroclinic block 10, locking tool 11, screw 12, bottom lock sleeve 2 center hole, Compress Spring 9 is installed, be supported on the lower end surface of lock shaft 3, briquetting 5 passes lock shaft 3 with the center hole of spring washer 8, inner nut 7 is fixed on spring washer 8, lock sleeve 2, by the screw thread on its external cylindrical surface, is fixed in the tapped hole of workpiece A1; The mounting hole of baroclinic block 10 bottom is fixed on workpiece B6 lower end surface by screw 12, the upper-end surface of baroclinic block 10 is identical locking inclined-plane, two angles of inclination, these two inclined-planes are to cross the face boundary of the center line of baroclinic block, the top on two inclined-planes is all with chamfering 17, and the center hole of baroclinic block 10 is socketed on lock shaft 3; Locking nut 4 to be fixed on the outside thread of lock shaft 3 by inner bolt hole and to be placed in the top of baroclinic block 10, the locking end face of locking nut 4 is in left-hand thread direction with chamfering 16, and the angle of inclination on the locking inclined-plane of baroclinic block 10 is less than the angle value of the Arctan of locking nut 4 and baroclinic block 10 contact surface friction ractor μ; Locking tool 11 is enclosed within locking nut 4.
The advantage that the present invention has and beneficial effect
In mechanism, installed a Compress Spring in the below of lock shaft, in locking process, lock shaft rotates in locking process, when improper use causes coupling mechanism force excessive, can play locking nut when preventing from tightening stuck, the effect of protection screw thread.The axial displacement in locking process of whole mechanism is that the screw displacement of lock shaft and the inclined-plane of baroclinic block rise superposing of displacement, and locking efficiency improves greatly; During locking, locking nut lower surface is pressed on the upper locking inclined-plane of baroclinic block, adds the effect of a spring washer, after total locking, is self-locking and locking; Locking tool special in mechanism, can play certain tamper effect, prevent misoperation from removing.
Accompanying drawing illustrates:
Fig. 1 is the locking mode schematic diagram of prior art;
Fig. 2 is quick-locking mechanism structural representation of the present invention, and wherein, 2-a is the sectional view of quick-locking mechanism structure, and 2-b is 2-a plan view;
Fig. 3 is baroclinic block of the present invention, locking nut and locking tool schematic diagram;
Fig. 4 is locking state schematic diagram of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is elaborated.
This structure primarily of lock sleeve 2, lock shaft 3, locking nut 4, composition such as baroclinic block 10 grade;
Locking nut 4, by screw thread and lock shaft 3 locking process, contacts with the baroclinic block 10 on band inclined-plane, and locking process axial displacement is screw displacement and inclined-plane rises superposing of displacement, reliable for what ensure to lock, with locking spring washer 8 in structure.
Baroclinic block 10, by screw 12, is fixed on workpiece B6, and lock sleeve 2, by the screw thread on its external cylindrical surface, is fixed in the tapped hole of workpiece A1;
Install Compress Spring 9 bottom lock sleeve 2 center hole, be supported on the lower end surface of lock shaft 3, briquetting 5 passes lock shaft 3 with the center hole of spring washer 8, and inner nut 7 is fixed on above the center hole of lock sleeve 2;
Locking nut 4 is fixed on the outside thread of lock shaft 3 by inner bolt hole, and locking nut 4 locks end face at loose hand of spiral with chamfering 16, reverse slope azimuthal rotational motion when being convenient to unclamp;
The internal surface of locking tool 11 and the outer surface Spielpassung of locking nut 4;
The locking bevel angle of baroclinic block 10, is less than the angle value of locking nut 4 and the Arctan of baroclinic block 10 contact surface friction ractor μ, the top on baroclinic block 10 inclined-plane with chamfering 17, reverse slope azimuthal rotational motion when being convenient to unclamp.
Locking procedure declaration:
Locking mechanism is for realizing the quick locking between workpiece A1 and workpiece B6;
Baroclinic block 10 is by screw 12, and be fixed on workpiece B6, integrally, drive locking nut 4 to rotate by locking tool 11, the internal thread of locking nut 4 screws the outside thread of lock shaft 3, is fixed on workpiece A1 fast;
During locking, lock shaft 3 is upwards strained and is pressed on spring washer 8, and spring washer 8 upwards leans against on the lower surface of inner nut 7, is strained by workpiece A1;
Compress Spring 9 is supported on the lower surface of lock shaft 3, prevents lock shaft 3 from rotating in locking process and to play locking nut 4 when preventing from tightening stuck, the effect of protection screw thread.
The axial displacement of locking process is that the screw displacement of lock shaft 3 and the inclined-plane of baroclinic block 10 rise superposing of displacement, and locking efficiency improves greatly;
During locking, locking nut 4 lower surface is pressed on the upper locking inclined-plane of baroclinic block 10, adds the effect of spring washer 8, after total locking, is self-locking and locking;
Special locking tool 11 can play certain tamper effect.
