Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail, can implement according to this with reference to specification sheets word to make those skilled in the art:
The invention provides a kind of locking and eject assembly, as Figure 1-5, this locking is ejected assembly and is comprised workpiece, base plate, stop block, elastic component, torsion component and elastic arm etc.Wherein:
Workpiece 3, on it, at least side is fluted, and number of recesses is identical with the quantity of stop block.This groove suits mutually with the gib head on elastic arm 10.The position interferenceed with stop block in the lower end of workpiece 3 internally tilts from top to bottom, and is affixed with stop block.This structure is convenient to the propagation of power, and ensures the path of motion of stop block.
Base plate 1, is provided with the insertion chamber of workpiece.Insert chamber and comprise insertion end and bottom.
Stop block 11, is provided with in the side-walls inserting chamber the stop 11 pieces interfered with a lateral edges of workpiece 3.Described stop block selects engineering plastics, to reduce required pressure in process of press in, and the weight of the whole assembly that slows down.Described stop block 11 offers groove 6.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 ensures the smooth surface of the groove 6 on stop block, ensures that L-type bending arm can the slip of smoothness in the groove 6 on stop block.
Elastic component 7, it is spring, is stainless steel spring, and applies predetermincd tension, ensures that slide block is in tension.Initial predetermincd tension is 2.5N, and extension spring rigidity is 1N/mm, and can provide enough restoring forces, overcomes paper box gravity and makes it eject.Stop block 11 is connected to described base plate 1 by it, and described elastic component 7 is set to when described stopper 11 is moved to bottom, produces 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 on described base plate 1.Torque spring selected by torsion component 5, material selection 65Mn, and its rigidity is (3.5Nm/deg), makes it have the power of automatically replying and guidance capability, improves stability.Steel wire diameter should meet torsion spring torsional stiffness and strength at repeated alternation.Torsional stiffness is too small, and restoring force can be caused to reduce; Excessive, cause required pressure in process of press in excessive.The angle of obliquity on its L-type bending arm and stop block inclined-plane is not excessive, to reduce required pressure in process of press in.
Elastic arm 10, it is connected on described stop block 11, extends, and described elastic arm 10 has the gib head corresponding with the groove 8 of described workpiece towards open side.Described elastic arm selects engineering plastics, to reduce required pressure in process of press in, and the weight of the whole assembly that slows down.Elastic arm there is a protruding block agreed with inclination compressive plane.Make when insertion workpiece, elastic arm can along inclination compressive plane to workpiece motion s.Elastic arm thickness 1-2mm, too smallly can not meet strength at repeated alternation requirement, excessive, causes 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.
Inclination compressive plane 13, it is arranged on described base plate 1, is arranged on the motion path of described elastic arm 10, to extrude described elastic arm 10, makes elastic arm 10 when moving to bottom, to the direction motion of the groove 8 near workpiece.Described inclination compressive plane is the inclined-plane tilted to center bottom.Inclination compressive plane angle of inclination is unsuitable excessive, in order to avoid elastic arm generation large deformation causes fracture.
The groove 6 of described stop block has the first location division, the second location division and the 3rd location division, and wherein, described first location division and the 3rd position point are in the both sides, top of the second location division.Described torsion component is set to: its one end is solidly connected to base 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 bending arm is positioned at the first location division; After workpiece is released, described L-type bending arm is positioned at the second location division, and now, workpiece is stuck in and inserts in chamber; When again workpiece being inserted least significant end, described L-type bending arm is positioned 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 lower than two ends, forms " V " shape.The nadir of the groove of stop block is balance position, and L-type bending arm is positioned at this position not by twisting resistance.Two vertexs of convex block upper end are in the same side of balance position perpendicular line, and the nadir of convex baffle plate lower end is then positioned at the opposite side of balance position perpendicular line.The perpendicular line of the nadir of the groove upper end of stop block is between the perpendicular line of two vertexs of convex block upper end, and the nadir of the groove upper end of stop block is not higher than any one of two vertexs of convex block upper end.
In locking process, be firmly pressed into workpiece, workpiece inserts chamber along workpiece and slides, until contact with stop block.Continue to apply pressure, workpiece and stop block continue move, and the elastic arm on stop block moves along workpiece insertion chamber and to the swing of close workpiece direction, and the L-type bending arm of bottom resilient component is along the concave slot sports of stop block.When workpiece motion s is to lowest order, L-type bending arm moves to the B point of stop block groove, i.e. the first location division.Now remove pressure, stop block workpiece returns under spring force, and 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 and work grooves fasten, and workpiece is locked.
Again applying pressure to workpiece makes workpiece motion s to lowest order, and L-type bending arm is point along the concave slot sports of stop block to D, i.e. the 3rd location division; Remove pressure, stop block and workpiece move under spring force, and elastic arm inserts chamber along workpiece and moves and swing to away from workpiece direction, and L-type bending arm is along the concave slot sports of stop block.When stop block moves to most significant bit, gib head and the work grooves of elastic arm are thrown off completely, and L-type bending arm moves to initial position A point.Workpiece is ejected.
Although embodiment of the present invention are open as above, it is not restricted to listed in specification sheets and embodiment utilization.It can be applied to various applicable the field of the invention completely.For those skilled in the art, can easily realize other amendment.Therefore do not deviating under the universal that claim and equivalency range limit, the present invention is not limited to specific details and illustrates here and the legend described.
