Embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is further described.Following examples only for technological scheme of the present invention is clearly described, and can not limit the scope of the invention with this.
Embodiment one: as Figure 1-Figure 4, a kind of multistage adjusting bolt, comprise center bolt 1, outer swivel nut 2, at least two-layer internal layer swivel nut 3, what give in the present embodiment is three grades of adjusting bolts, namely only has one deck internal layer swivel nut 3, when needs realize the adjustment of N level, only need to arrange N-2 layer internal layer swivel nut 3, between center bolt 1 and internal layer swivel nut 3, between internal layer swivel nut 3 and outer swivel nut 2, and be mutually threaded between internal layer swivel nut 3.
As Figure 1-Figure 4, center bolt 1, internal layer swivel nut 3 radially slides and is provided with two bullet pins, two bullet pins are axially interspersed along it, the inner side of outer swivel nut 2 and internal layer swivel nut 3 offers the locating slot 5 coordinated with bullet pin one_to_one corresponding accordingly, locating slot 5 is made up of lock face 6 and arc guide surface 7, lock face 6 parallels with the glide direction of bullet pin, in the present embodiment, lock face 6 is a plane, be arranged to arc shaped surface in addition also passable, the plane symmetry setting at locating slot 5 its center line place relative on outer swivel nut 2 and internal layer swivel nut 3, two bullet pins are along center bolt 1, internal layer swivel nut 3 radial direction is interspersed, in the preferably technological scheme provided in the present embodiment, angle between two bullet pins on described center bolt 1, angle between two bullet pins on described internal layer swivel nut 3 is 180 °.
As shown in figs 2-4, bullet pin has the guide surface matched with the arc guide surface 7 of corresponding locating slot 5, when bullet pin inserts in locating slot 5, one end matches with lock face 6, its guide surface matches with arc guide surface 7, when operator is towards lock face direction center of rotation screw rod 1, one end matches with lock face 6, locked, during present dynasty's counter-rotation, by coordinating of guide surface and arc guide surface 7, bullet pin skids off in locating slot 5, length adjustment can be carried out, by coordinating of guide surface and arc guide surface 7, not only be convenient to bullet pin skid off in locating slot, and not easily scuffing is caused to arcuate guide 7 face.
As shown in the FIG., bullet pin comprises pin body 4 in rigidity and elastic component 8, center bolt 1, internal layer swivel nut 3 radially offer chute 9, pin body 4 slides and is arranged in corresponding chute 9, elastic component 8 is arranged between pin body 4 and chute 9, elastic component 8 is spring, in addition elastic component 8 is not limited to the spring in the present embodiment, as rubber parts etc. can use at this, the position-limit mechanism preventing both to be separated is provided with between pin body 4 and chute 9, position-limit mechanism is not designing points of the present invention, and no longer this repeats concrete structure.
Embodiment two: be with the difference of embodiment one: center bolt 1, internal layer swivel nut 3 offers two length directions along its axially extended mounting groove, the depth direction of mounting groove is along center bolt 1, the radial direction of internal layer swivel nut 3 extends, slide in mounting groove and be provided with sliding seat, sliding seat is connected with corresponding bullet pin, the locking framework both being locked at least two working positions is provided with between sliding seat and corresponding mounting groove, can by regulating the position between sliding seat and mounting groove, then the distance between two bullet pins is regulated, thus the length controlling every grade of adjustment can be reached, locking framework in the present embodiment is not designing points of the present invention, as long as the locking framework that the parts that two are slided mutually can be locked at least two working positions can use at this, concrete structure does not repeat them here.
Working principle of the present invention: before adjustment, center bolt 1, internal layer swivel nut 3 and outer swivel nut 2 are matched with locating slot 5 by one of them bullet pin between every grade, another one bullet pin shrinks in the chute 9 of center bolt 1 or internal layer swivel nut 3, when needs realize multistage adjustment, operator only needs center of rotation screw rod 1, by coordinating of arc guide surface 7 and the guide surface on bullet pin, bullet pin on center bolt 1 skids off in corresponding locating slot 5, after regulating certain distance, the bullet pin shunk in chute 9 inserts in corresponding locating slot 5, matched with the lock face on bullet pin by lock face 6, center bolt 1 and close first layer internal layer swivel nut 3 are fixed as one, first layer internal layer swivel nut 3 is driven to rotate when being rotated further center bolt 1, corresponding bullet pin is skidded off in corresponding locating slot 5, regulate successively, its principle is similar to above-mentioned.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
