Specific embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings, to make those skilled in the art with reference to description literary composition
Word can be implemented according to this:
The invention provides assembly is ejected in a kind of locking, as Figure 1-5, this locking eject assembly include workpiece, base plate,
Stop block, elastic component, torsion component and elastic arm etc..Wherein:
Workpiece 3, at least side is fluted thereon, and number of recesses is identical with the quantity of stop block.This groove and elastic arm
Gib head phase on 10 suits.The position interferenceed with stop block in the lower end of workpiece 3 internally tilts from top to bottom, and and stop block
It is affixed.This structure is easy to the propagation of power, and ensures the movement locus of stop block.
Base plate 1, is provided with the insertion chamber of workpiece.Insertion chamber includes insertion end and bottom.
Stop block 11, the side-walls in insertion chamber are provided with 11 pieces of the stop interfering with lateral edges of workpiece 3.Institute
State stop block and select engineering plastics, to reduce desirable pressure in process of press in, and the weight of the whole assembly that slows down.Described backstop
Fluted 6 are opened up on block 11.Groove 6 groove width on described stop block should be greater than the width of the l type bending arm of torsion component 5,
And the groove 6 on guarantee stop block smooth surface it is ensured that l type bending arm can be smooth in the groove 6 on stop block cunning
Dynamic.
Elastic component 7, it is spring, is stainless steel spring, and applies pretightning force it is ensured that slide block is in tension.Just
Beginning pretightning force is 2.5n, and extension spring rigidity is 1n/mm, and is provided that enough restoring forces, overcomes paper box gravity so that it is ejected.It will
Stop block 11 connects to described base plate 1, and described elastic component 7 is set to, when described stopper 11 is moved to bottom, produce
Elastic-restoring force.Concrete structure is: spring one end is fixed on base plate, and the other end connects the boss of stop block upper end.
Torsion component 5, its one end is buckled in the groove 6 of described stop block, and the other end of torsion component 5 is fixed in institute
State on base plate 1.Torsion component 5 selects torque spring, material selection 65mn, and its rigidity is (3.5n m/deg) so as to have certainly
Dynamic restoring force and guidance capability, improve stability.Steel wire diameter should meet torsion spring torsional rigidity and fatigue strength.Torsional rigidity mistake
Little, restoring force can be led to reduce；Excessive, lead to desirable pressure in process of press in excessive.Its l type bending arm and stop block inclined-plane
Pressure angle not excessive, with reduce in process of press in desirable pressure.
Elastic arm 10, it is connected on described stop block 11, towards open side extend, and have on described elastic arm 10 with
The corresponding gib head of the groove 8 of described workpiece.Described elastic arm selects engineering plastics, to reduce desirable pressure in process of press in,
And the weight of the whole assembly that slows down.One protruding block being agreed with inclination compressive plane is had on elastic arm.So that in insertion workpiece
When, elastic arm can be along inclination extruding towards workpiece motion s.Elastic arm thickness 1-2mm, too small can not to meet fatigue strong
Degree requires, excessive, leads to guide block 12 in paper box process of press in excessive with guide rail 13 lateral pressure, and then increases the required pressure of press-in
Power.
Tilt compressive plane 13, it is arranged on described base plate 1, is arranged on the motion path of described elastic arm 10, to squeeze
Press described elastic arm 10 so that elastic arm 10 is when moving to bottom, move in the direction to the groove 8 near workpiece.Described incline
Tiltedly compressive plane is the inclined-plane tilting to center bottom.Tilt compressive plane angle of inclination unsuitable excessive, in order to avoid elastic arm occurs big change
Shape leads to rupture.
The groove 6 of described stop block has the first location division, the second location division and the 3rd location division, wherein, described first
Location division and the 3rd position point are in the top both sides of the second location division.Described torsion component is set to: its one end is solidly connected to bottom
Plate, and other end l type bending arm is buckled in the groove of described stop block, and when workpiece is inserted into least significant end, described l type folding
Curved boom is located at the first location division；After workpiece is released, described l type bending arm is located at the second location division, and now, workpiece is stuck in slotting
Enter intracavity；When again by workpiece insertion least significant end, described l type bending arm is located at the 3rd location division.
Wherein, the upper end of the convex block in the upper end of the groove of described stop block and the groove of stop block is all middle low
In two ends, form " v " shape.The minimum point of the groove of stop block is equilbrium position, and l type bending arm is not reversed positioned at this position
Power.In the same side of equilbrium position vertical line, the minimum point of convex baffle plate lower end is then located at puts down two peaks of convex block upper end
The opposite side of weighing apparatus position vertical line.The vertical line of the minimum point of groove upper end of stop block is in two peaks of convex block upper end
Vertical line between, and the minimum point of the groove upper end of stop block be not higher than convex block upper end two peaks any one
Individual.
During locking, firmly it is pressed into workpiece, workpiece slides along workpiece insertion chamber, until contacting with stop block.Continue to apply
Plus-pressure, workpiece continues motion with stop block, and the elastic arm on stop block moves and near workpiece direction along workpiece insertion chamber
Swing, the l type bending arm of bottom resilient component is along the concave slot sports of stop block.When workpiece motion s are to lowest order, l type bending arm is transported
Move to the b point of stop block groove, i.e. the first location division.Now remove pressure, stop block workpiece returns under spring force, l
Type bending arm moves to the c point of stop block groove, i.e. the second location division.The gib head of elastic arm is fastened with work grooves, workpiece quilt
Locking.
Applying pressure to workpiece again makes workpiece motion s to lowest order, and l type bending arm is along the concave slot sports of stop block to d
Point, i.e. the 3rd location division；Remove pressure, stop block is moved under spring force with workpiece, elastic arm is along workpiece insertion chamber fortune
Move and swing to away from workpiece direction, l type bending arm is along the concave slot sports of stop block.When stop block moves to highest order, elasticity
The gib head of arm is completely disengaged with work grooves, and l type bending arm moves to initial position a point.Workpiece is ejected.
Although embodiment of the present invention is disclosed as above, it is not restricted to listed in description and embodiment
With.It can be applied to various suitable the field of the invention completely.For those skilled in the art, can be easily
Realize other modification.Therefore under the general concept being limited without departing substantially from claim and equivalency range, the present invention does not limit
In specific details with shown here as the legend with description.
