Embodiment
The structural representation of a kind of activity combination pin that Fig. 3 provides for the present embodiment, the use view of the activity combination pin that Fig. 4 provides for the present embodiment, in conjunction with Fig. 3 and shown in Figure 4, the activity combination pin that the present embodiment provides, comprise columnar pin shaft 4, an end of bearing pin 4 is provided with boss 5, has two holes 6 on the boss 5, two holes 6 lay respectively at the relative both sides of boss 5, and the axis in two holes 6 is not on the same straight line; The activity combination pin also comprises elastic ring 7, and elastic ring 7 is the ring-type with opening, and insert respectively in two holes 6 at its two ends.The diameter of bearing pin 4 is preferably the diameter of standard openings pin in the activity combination pin.Shape and the pinhole shape of bearing pin 4 are complementary, as pinhole shape be circular hole then bearing pin 4 be cylindrical body, if pinhole shape is polygonal hole, then bearing pin 4 is corresponding polygonal prism.When boss 5 be shaped as cylindrical boss the time, two holes are positioned at the relative both sides of boss and get final product, for example two holes lay respectively near the position of two end points of a certain diameter on this cylinder boss one cross section, and the axis in two holes 6 is not on the same straight line.
The activity combination pin that the present embodiment provides is comprised of a bearing pin 4 and an elastic ring 7.An end of bearing pin 4 is provided with a boss 5, and the axis that 6, two holes 6, a hole is respectively arranged in boss 5 relative both sides is not on the same straight line, and preferred hole 6 is blind hole, is used for installing location elastic ring 7.Owing to stagger relatively in the position in the hole 6 of the relative both sides of the boss 5 of bearing pin 4, can produce an elastic force after elastic ring 7 assemblings, according to the elastic force of elastic ring 7, swing elastic ring 7 by the operator, can there be two states in elastic ring 7, an off-position and a working position.
Concrete: the elastic ring 72 of off-position is for the state of pendulum to the oblique upper of boss 5, shown in the double dot dash line among Fig. 4.The elastic ring 72 of this off-position is used for this activity combination pin is carried out dismounting, and the operator can remove bearing pin 4 by mentioning elastic ring 72; The elastic ring 71 of working position is the state of pendulum to the below of boss 5, and elastic ring 71 is enclosed within axle head 2 outsides and leans against on the bearing pin 4, utilizes the elastic force of elastic ring 71, and bearing pin is locked in axle head 2, plays the locking effect, can prevent bearing pin 4 disengagements.Dotted line among Fig. 4 represents the axle head 2 of lock shaft.
Activity combination pin provided by the invention, the columnar pin shaft that has boss by an end is set, the both sides that boss is relative have not two holes on the same straight line of axis, the two ends of elastic ring are inserted respectively in these two holes and are become ring-type, because two hinges of elastic ring are not on same straight line, elastic ring produces elastic force after being anchored on the bearing pin, lock, the self-locking of realization activity combination pin guarantees to vibrate, can not throw off when rotating with lock shaft in the activity combination pin.
This kind activity combination pin relatively with cotter pin of the prior art:
When 1, having solved the employing cotter pin during dismounting, need to be inconvenient by the instrument dismounting, by swinging elastic ring 7, easily dismounting;
2, prior art split shed pin Reusability repeatedly, the waste material, and the activity combination pin that the present embodiment provides since the two states that the swing of its elastic ring 7 exists can reuse;
3, prior art split shed pin connects the pin of lock shaft for realizing by distortion, and relatively strength deficiency has unreliable factor, and the activity combination pin pin shaft structure that the present embodiment provides is single cylinder, and undeformed, intensity is high, and is reliable.
Preferred as technique scheme.Boss 5 has the relative both sides of extension 51 that 51, two holes 6 of extension of stretching out bearing pin 4 are positioned at boss 5.
Preferred as technique scheme, the axis in two holes 6 is positioned at same plane, is 45 ° of angles between the axis vertical plane of this plane and bearing pin 4.
Preferred as technique scheme, joint shape and the bearing pin 4 of boss 5 are complementary, and namely boss 5 and the joint of bearing pin 4 are the structure identical with bearing pin 4, and for example bearing pin 4 is round column structure, and then the joint of boss 5 and bearing pin 4 also is round column structure.And for the ease of the processing to extension, also punch for the ease of the extension at boss 5, the extension 51 of preferred boss 5 is cuboid.
Preferred as technique scheme, the length of boss 5 is 1.6 ~ 2.4 times of bearing pin 4 diameters, the top of the extension 51 of boss 5 is provided with chamfering.
Preferred as technique scheme, hole 6 is blind hole, the insertion end of the diameter of blind hole and elastic ring 7 is complementary.
Preferred as technique scheme, the degree of depth of blind hole is 2/3 of bearing pin 4 diameters, the diameter of elastic ring 7 is 1.5 ~ 3.5mm.
Preferred as technique scheme, the ring-type diameter that elastic ring 7 surrounds are 1.2 ~ 1.3 times of axle head 2 diameters of lock shaft.
Preferred as technique scheme, the length of bearing pin 4 are 1.25 ~ 1.35 times of axle head 2 diameters of lock shaft.
Activity combination pin provided by the invention, the columnar pin shaft 4 that has boss 5 by an end is set, boss 5 relative both sides have not two holes 6 on the same straight line of axis, insert in two holes 6 and be the annular resilient circle 7 with opening, because two hinges of elastic ring 7 are not on same straight line, elastic ring 7 produces elastic force after being anchored on the bearing pin 4, lock, the self-locking of realization activity combination pin guarantees to vibrate, can not throw off when rotating with lock shaft in the activity combination pin.
It should be noted that at last: above each embodiment is not intended to limit only in order to technological scheme of the present invention to be described; Although with reference to aforementioned each embodiment the present invention is had been described in detail, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technological scheme that aforementioned each embodiment puts down in writing, and perhaps some or all of technical characteristics wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the scope of various embodiments of the present invention technological scheme.
