Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.As long as in addition, technical characteristic involved in the various embodiments of the present invention described below
Not constituting a conflict with each other can be combined with each other.
As shown in Figure 1,2 and 3, mandril retaining mechanism preferred embodiment of the present invention includes mandril 1, protective cap 2, steel ball 3, pushes away
Spring 4, stop screw 5, spring 6 and lid 7.
1 top of mandril has a radial first groove 1-1 of circle, and the first groove 1-1 size can accommodate diameter
Steel ball 3.There is the raised 1-2 of second groove of circle Intermediate Gray in the middle part of mandril 1, the second groove among raised 1-2 can accommodateRubber seal.Mandril base diameter byTapering transition is
Protective cap 2 is the hollow caging member of many places through-hole open at one end, and the shape of protective cap is that both ends are respectively large and small put down
The irregular roundness cylindricality in face, big in-plane have longitudinal kidney-shaped stepped hole, and stepped hole is kidney-shaped limiting slot inside protective cap
2-1-A, outside are small kidney slot 2-1-B.There is waist through hole 2-2 in the middle part of facet, have on the cylindrical surface of facet side
One longitudinal kidney-shaped limiting slot 2-3, protective cap top center have a circular through hole 2-4, and there are two straight for protective cap inner cavity tool
Diameter is 1, highly for 5 guide rod 2-5；
Steel ball 3 is diameterStandard steel ball；
Push spring 4 is the spring that minimum diameter is 1.4, and push spring 4 is corresponding with the guide rod 2-5 in protective cap 2, guide rod 2-
5 be the guiding core bar of push spring 4；
Stop screw 5 is made of the M3 screw rod 5-1 of one and limited post 5-2, has 0.5 × 0.5 at the top of screw rod 5-1
Pilot trench 5-3, stop screw 5 are corresponding with longitudinal kidney-shaped limiting slot 2-4 in protective cap 2；
Spring 6 is the spring that minimum diameter is 4.4, spring 6 and 1 base diameter of mandrilIt is corresponding；
Lid 7 is that centre is boss 7-1, is around lid 7-2, and inside is the pipe 7-3 to connect with boss 7-1.Boss
Shape is corresponding with 2 inner hollow core of protective cap, and shape is similar, but than 2 inner hollow core undersized of protective cap, guarantees protective cap 2
It axially can freely up and down be moved in boss 7-1, the hole of boss 7-1 and the perforation of the center pipe 7-3 is stepped hole, has macropore in stepped hole
7-4-1, aperture 7-4-2, stepped hole and mandril 1 are adapted, and the raised 1-2 diameter of mandril 1 is less than macropore 7-4-1, but protrusion 1-2
Diameter is greater than aperture 7-4-2, and aperture plays position-limiting action, guarantees that the raised 1-2 of mandril 1 can only be in the macropore 7-4-1 of stepped hole 7-4
In be free to move axially.There are two the blind hole 7-5 of same size, blind hole 7-5 and push springs 4 to be adapted on boss 7-1, blind hole 7-5
Internal diameter diameter is greater than the maximum outside diameter of push spring 4.Have on a transverse plane of boss 7-1 perforation stepped hole 7-4 through-hole 7-6, through-hole 7-6 with
Steel ball 3 is adapted, and through-hole 7-6 is more bigger than steel ball 3, and steel ball 3 can move freely in through-hole 7-6.The side cylindrical surface of boss 7-1
On there is threaded hole 7-7, threaded hole 7-7 to match with stop screw 5.
Mandril 1Cylindrical surface is packed into the stepped hole 7-4 of lid 7 together after being packed into spring 6, in 6 effect of elastic resistance of spring
Under, mandril 1 moves in stepped hole 7-4 to the direction aperture 7-4-2 of stepped hole, and aperture 7-4-2 has the raised 1-2 of mandril 1
Position-limiting action, mandril 1 can only move in limited range；
Assembling process and working principle of the invention is described below.
Assembling process of the invention is as follows：
After two guide rod 2-5 in protective cap 2 put on push spring 4 respectively, it is encased on the boss 7-1 of lid 7, steel ball 3
It is encased in the through-hole 7-6 of lid 7, after mobile 1 to the first groove 1-1 of mandril is flushed with through-hole 7-6 in lid 7, steel ball 3 is caught in
First groove 1-1 presses down on protective cap 2, and after steel ball 3 enters the kidney-shaped stepped hole 2-1 of protective cap 2, mandril is in 6 drag of spring
The lower movement of effect.
Protective cap 2 moves downwardly to the longitudinal kidney-shaped limiting slot 2-4 and lid of protective cap 2 along the intermediate lands 7-1 of lid 7
7 threaded hole 7-7 installs stop screw 5 to after just, guarantees that protective cap 2 can only be in the fixed range of stop screw 5, along waist
Shape limiting slot 2-4 longitudinal movement.
Lid 7 is installation connecting element, is the structural support of mandril insurance institution, is boss 7-1 and perforation among guarantee
Pipe 7-3 structure type it is constant in the case where, lid 7-2 can accordingly change according to the structure type that need to be connected.
Spring 6 is in lid 7 with after other structure connections that need to be connect, and spring 6 need to be in contact with a stationary plane, to protect
Card spring 6 is in compressive state, can provide driving force for mandril 1.
Working principle of the present invention is as follows：As Fig. 2 guarantees lock since the wall thickness at the big plane position on the left of boss is relatively thin
Determining steel ball under state can contact with protective cap inner wall, so that steel ball is blocked by protective cap inner wall under lock state, to make to illustrate
The left part of middle steel ball is stuck in the first groove, and mandril is locked, and mandril cannot move up and down at this time；Protection is pressed downwards
Cap, when big kidney slot drops to steel ball position, since the constraint on the right side of steel ball is released from, under the force of a spring, top
Steel ball is squeezed out the first groove by bar, can release locking of the steel ball to mandril, since the width of small kidney slot is less than steel ball size,
Steel ball can be limited in big kidney slot；Meanwhile small waist-shaped hole also has resigning effect, can reduce the projected depth of big kidney slot
It still ensures that steel ball can be sufficiently disengaged from the first groove, to save material, reduces volume；Protective cap is unclamped, then protective cap exists
Push spring effect is lower to be resetted, and steel ball is squeezed back again in the first groove, relocks mandril.Repeat the above movement, then it can be anti-
Multiple locking and unlocking mandril.By replacing the push spring of varying strength or adjusting the precommpression degree of push spring, thus it is possible to vary press
The size of dynamics needed for protective cap, so that the specific triggering dynamics of setting, avoids false triggering or misread lock, reduce accident
Rate.In addition, for installing bolt or plug etc., the lower end of bolt or plug is withstood on boss for the through-hole that opens up at the top of protective cap
Surface can preferably guarantee accidentally pressure protective cap to cause to solve for replacing protective cap to bear pressure in a non-operative state
Lock.The shape of protective cap and boss, it is ensured that protective cap will not lead to steel ball and big kidney-shaped because accidentally rotating in the locked state
Hole site does not correspond to, to guarantee that steel ball is bound to enter big waist-shaped hole when pressing protective cap.
(not shown) in other embodiments can offer corresponding screw hole, inoperative shape on boss and protective cap
It is locked under state by screw, to guarantee that protective cap can never be misused pressure.When it is desired to be used, then screw of dismantling.
As it will be easily appreciated by one skilled in the art that the above is merely preferred embodiments of the present invention, not to limit
The present invention, any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in this
Within the protection scope of invention.
