[embodiment]
It is low that the utility model aims to provide a kind of cost, easy to use, and reliable lock is effective, and the high pull-rod type controlling device of supporting power.
Below introduce characteristics of the present utility model and advantage in detail by specific embodiment of the utility model and accompanying drawing.
Embodiment one:
The structural principle of at first understanding the utility model and being relied on: as shown in Figure 1, torsion spring 2 is placed on the pull bar 1, dextrorotation torsion spring 2 (is example to torsion spring with dextrorotation) is held pull bar 1 tightly, this moment is when all being subjected to the axial force of balance when the first lap of torsion spring 2, torsion spring 2 can slide on pull bar 1 after the overcome friction, but if just local (is example with a m) is subjected to axial force a, this axial force a can make the some n place end perk of the opposite side of invocation point m correspondence, slightly sink with time point m place end, and axial force a can tell a lateral force b and acted on the pull bar 1 this moment, the lateral force b that acts on pull bar 1 is decomposed into radial force and the axial force to pull bar again, if axial force a is big more, then the radial force that decomposites of lateral force b is big more, cause the frictional force between torsion spring 2 and the pull bar 1 big more, so axial force a is big more, then the pull bar 1 of 2 armfuls of torsion springs is tight more, torsion spring 2 is not easy to slide on pull bar 1 more, and is enough big so that till destroying torsion spring 2 or pull bar 1 up to the active force of axial force a; And if left-handed torsion spring 2, the internal diameter of torsion spring 2 increases, pull bar 1 and torsion spring 2 no longer hug, pull bar 1 is free to slide between torsion spring 2, apply axial force a this moment, but do not reach pull bar 1 after some m and some two ends, n place sink to upwarping, so still can not hinder pull bar 1 between torsion spring 2, to slide freely.
Based on this principle, the pull-rod type controlling device that present embodiment one is provided, its structure and component thereof such as Fig. 2～shown in Figure 9, include pull bar 1, be with torsion spring 2, snap close 3 and drag link sleeve 4 on the described pull bar 1.Wherein torsion spring 2 remains on the external diameter that internal diameter under the stress not equals pull bar 1, torsion spring 2 two ends radially respectively are provided with one section spring head 2-1 and spring head 2-2, the two ends of this torsion spring 2 is inserted respectively in snap close 3 and the drag link sleeve 4, wherein snap close 3 can change the size of torsion spring 2 internal diameters, 4 of drag link sleeves and snap close 3 interlocks, fixing jointly or mobile torsion spring 2; The end face that torsion spring 2 is inserted the termination in the drag link sleeve 4 contacts with drag link sleeve 4 inner just parts, if this is because all contacts, then to act on the distribution of forces of torsion spring 2 end faces even for drag link sleeve 4, therefore causes torsion spring 2 to slide on pull bar 1 and can't reach the effect of fixed drawing-rod 1.For satisfying the part contact, being designed to drag link sleeve 4 inserts an end inside of torsion spring termination and offers oblique groove 4-1, the platform 4-3 that contacts with the end face part of torsion spring termination is arranged on this groove 4-1, simultaneously offer the spring head groove 4-1 of the spring head 2-2 that can hold this termination of torsion spring, and be provided with drag link sleeve fixed groove 4-4 in another termination of drag link sleeve 4 and arbitrarily slide to prevent drag link sleeve 4 at this; Snap close 3 is set for the internal diameter size of control torsion spring 2, which is provided with plectrum 3-2 and spring head groove 3-1, and main effect is a control twisting torsion spring 2, and wherein the spring head 2-1 on the other end of torsion spring 2 places within the spring head groove 3-1.
In said structure, because torsion spring 2 is inserted the end face of the termination in the drag link sleeve 4 and is contacted with drag link sleeve 4 inner just parts, so the length of the platform 4-3 that contacts with the end face part of torsion spring termination is shorter, in order to reach the locking purpose, the length that obtains this platform 4-3 according to test is good with the quadrant girth less than ring place circumference in the drag link sleeve 4, more little effect is good more, but also will consider platform simultaneously too little is not enough to load-bearing again, easily be damaged, so concrete length size is set according to actual needs.
As Fig. 2, as follows during the work of this device: left-handed snap close 3, it is left-handed to drive torsion spring 2 (present embodiment torsion spring 2 rotation directions are a left side), and this moment, the spring head 2-2 of torsion spring 2 was stuck in the spring head groove 4-2 motionless, so it is big that the internal diameter of torsion spring 2 becomes, pull bar 1 can be free to slide in drag link sleeve 4, snap close 3, torsion spring 2; Dextrorotation snap close 3 makes that driving torsion spring 2 holds pull bar 1 tightly, spurs pull bar 1 or pushing drawing rod cover 4 this moment, and pull bar 1 can not slide, unless active force is enough to damage pull bar 1 or torsion spring 2.The utility model structure is also uncomplicated, but its design is but very ingenious.
Embodiment two:
Be with embodiment's one difference, torsion spring 2 on the embodiment two respectively has two with drag link sleeve 4, be symmetrically distributed in the both sides of snap close 3, wherein the spring head groove 3-1 on the snap close 3 runs through snap close 3, and the rotation direction of two torsion springs is opposite, a left-handed dextrorotation, such two torsion spring 2 synchronous effects are on pull bar 1, but increased the weight of load-bearing, reliable lock is difficult for being damaged.
As shown in figure 10, when embodiment two is applied to the automotive seat regulator, one in cover is fixed in the FE Tiler 5 of automotive seat bottom on present embodiment, left-handed snap close 3, move forward and backward to suitable position by pull bar 1 control seat then, dextrorotation snap close 3 is held pull bar 1 back fixedly snap close 3 tightly and is got final product simple, the convenience of use then.
The above embodiment has only expressed several mode of execution of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
