Specific embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and Examples
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 additionally, technical characteristic involved in invention described below each implementation method
Not constituting conflict each other can just be mutually combined.
As shown in Figure 1,2 and 3, push rod retaining mechanism of the present invention preferred embodiment includes push rod 1, protective cap 2, steel ball 3, pushes away
Spring 4, stop screw 5, spring 6 and lid 7.
The first groove of the circle 1-1, the first groove 1-1 that the top of push rod 1 has radial direction is sized to receiving diameter
Steel ball 3.There is the raised 1-2 of second groove of circle Intermediate Gray at the middle part of push rod 1, and the second groove in the middle of raised 1-2 can be accommodatedRubber seal.Push rod base diameter byTapering transition is
Protective cap 2 is the hollow caging member of one end open many places through hole, and the profile of protective cap is large and small flat for two ends are respectively
The irregular roundness cylindricality in face, big in-plane has longitudinal kidney-shaped stepped hole, and stepped hole is kidney-shaped stopper slot inside protective cap
2-1-A, outside is small kidney slot 2-1-B.Facet middle part has waist through hole 2-2, has on the face of cylinder of facet side
One longitudinal kidney-shaped stopper slot 2-3, protective cap top center has a manhole 2-4, and protective cap inner chamber has two directly
Footpath is 1, highly for 5 guide post 2-5；
Steel ball 3 is diameterStandard steel ball；
Pushes away spring 4 is the spring that minimum diameter is 1.4, and pushes away spring 4 is corresponding with the guide post 2-5 in protective cap 2, guide post 2-
5 is the guiding core bar of pushes away spring 4；
Stop screw 5 is made up of the M3 screw rods 5-1 and limited post 5-2 of one, screw rod 5-1 top have 0.5 × 0.5 rise
Pilot trench 5-3, stop screw 5 is corresponding with the longitudinal kidney-shaped stopper slot 2-4 in protective cap 2；
Spring 6 is the spring that minimum diameter is 4.4, spring 6 and the base diameter of push rod 1It is corresponding；
Lid 7 is boss 7-1 for centre, is around lid 7-2, and inside is the pipe 7-3 connected with boss 7-1.Boss
Profile is corresponding with the inner hollow core of protective cap 2, and shape is similar, but than the inner hollow core undersized of protective cap 2, it is ensured that protective cap 2
Axially can freely up and down be moved in boss 7-1, boss 7-1 is stepped hole with the hole of pipe 7-3 throughs, there is macropore in stepped hole
7-4-1, aperture 7-4-2, stepped hole are adapted with push rod 1, and the raised 1-2 diameters of push rod 1 are less than macropore 7-4-1, but projection 1-2
With diameter greater than aperture 7-4-2, aperture plays position-limiting action, it is ensured that the raised 1-2 of push rod 1 can only be in the macropore 7-4-1 of stepped hole 7-4
In be free to move axially.There are two blind hole 7-5 of formed objects, blind hole 7-5 to be adapted with pushes away spring 4 on boss 7-1, blind hole 7-5
Maximum outside diameter of the internal diameter footpath more than pushes away spring 4.Have on one transverse plane of boss 7-1 insertion 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 be moved freely in through hole 7-6.The side face of cylinder of boss 7-1
On there is screwed hole 7-7, screwed hole 7-7 to be engaged with stop screw 5.
Push rod 1Load in the lump after face of cylinder loading spring 6 in the stepped hole 7-4 of lid 7, in the effect of elastic resistance of spring 6
Under, push rod 1 is moved in stepped hole 7-4 to the aperture 7-4-2 directions of stepped hole, and aperture 7-4-2 has to the raised 1-2 of push rod 1
Position-limiting action, push rod 1 can only be moved in limited range；
Assembling process of the invention and operation principle is described below.
Assembling process of the invention is as follows：
After two guide post 2-5 in protective cap 2 put pushes away 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 the mobile groove of push rod 1 to the first 1-1 is flushed with through hole 7-6 in lid 7, steel ball 3 is snapped 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, push rod is in the drag of spring 6
The lower motion of effect.
Protective cap 2 moves downwardly to longitudinal kidney-shaped stopper slot 2-4 and lid of protective cap 2 along the intermediate lands 7-1 of lid 7
After 7 screwed hole 7-7 is aligned, stop screw 5 is installed, it is ensured that protective cap 2 can only be in the scope that stop screw 5 is fixed, along waist
Shape stopper slot 2-4 lengthwise movements.
Lid 7 is installation connecting element, is the structural support of push rod insurance institution, is boss 7-1 and insertion in the middle of ensureing
Pipe 7-3 structure types it is constant in the case of, lid 7-2 can accordingly change according to the structure type that need to be connected.
Spring 6 is that spring 6 need to be in contact with a stationary plane after the structure connection that lid 7 need to be connected with other, to protect
Card spring 6 is in compressive state, can provide driving force for push rod 1.
Operation principle of the invention is as follows：Such as Fig. 2, because the wall thickness at the big plane position on the left of boss is relatively thin, it is ensured that lock
Steel ball can be contacted with protective cap inwall under determining state so that under lock-out state, steel ball is blocked by protective cap inwall, so that diagram
The left part of middle steel ball is stuck in the first groove, and push rod is locked, and now push rod can not be moved up and down；Press protection downwards
Cap, when big mounting hole drops to steel ball position, because the constraint on the right side of steel ball is released from, under the force of a spring, top
Steel ball is extruded the first groove by bar, you can release locking of the steel ball to push rod, because the width of small mounting hole is less than steel ball size,
Steel ball can be limited in big mounting hole；Meanwhile, small waist-shaped hole also has resigning to act on, and can reduce the projected depth of big mounting hole
Still ensure that steel ball can be sufficiently disengaged from the first groove, so as to save material, reduce volume；Protective cap is unclamped, then protective cap exists
Pushes away spring effect is lower to be resetted, and steel ball is squeezed back in the first groove again, relocks push rod.Acted more than repeating, then can be anti-
Multiple locking and unblock push rod.By changing the pushes away spring of varying strength or the precommpression degree of adjustment pushes away spring, thus it is possible to vary press
The size of the dynamics needed for protective cap, so as to set specific triggering dynamics, it is to avoid lock is misread in false triggering, reduces accident and occurs
Rate.In addition, the through hole that protective cap top opens up is used for installation bolt or stopper etc., the lower end of bolt or stopper is withstood on boss
Surface, for bearing pressure instead of protective cap in a non-operative state, can preferably ensure that solution will not be caused by pressure protective cap by mistake
Lock.The shape of protective cap and boss, it is ensured that protective cap will not cause steel ball and big kidney-shaped because missing rotation in the locked state
Hole site does not correspond to, so as to ensure to press steel ball during protective cap be bound to enter big waist-shaped hole.
In other embodiments (not shown), corresponding screw, inoperative shape can be offered on boss and protective cap
Locked by screw under state, to ensure 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 these are only presently preferred embodiments of the present invention, it is not used to limit
The present invention, all any modification, equivalent and improvement made within the spirit and principles in the present invention etc., should be included in this
Within the protection domain of invention.
