Embodiment
As Figure 1-4, a kind of compression distance adjustable type spring assembly, comprise spring 1, described spring 1 two ends are affixed upper cover plate 21 and lower cover plate 22 respectively, upper cover plate 21 and lower cover plate 22 are solid slabs, centre does not have perforate, a retractable drag link mechanism 3 is connected with between upper cover plate 21 and lower cover plate 22, described drag link mechanism 3 comprises the positioning rod 31 with cavity 30, described positioning rod 31 one end and lower cover plate 22 affixed, affixed mode can be that to be spirally connected also can be welding or riveted joint etc., the other end is flexibly connected movement rod 32 and movement rod 32 is inserted in cavity 30, described movement rod 32 is away from the affixed upper cover plate 21 in the one end be inserted in cavity 30, the length of described positioning rod 31 is greater than the length of movement rod 32, in the present invention, movement rod 32 can telescopic moving back and forth in positioning rod 31, described positioning rod 31 is also provided with a compression distance controlling mechanism 4, described compression distance controlling mechanism 4 comprises and to be arranged on positioning rod 31 sidewall and along the equally distributed some positioning holes 41 of axis of positioning rod 31, described positioning hole 41 is communicated with cavity 30, locating stud 42 is inserted with and this locating stud 42 extends in cavity 30 in one of them positioning hole 41, when movement rod 31 move down basis to locating stud 42 time, movement rod 31 can not move again, be position length, locating stud 42 can insert and extract from positioning hole 41, both are for removably connecting, when needs regulate position length, locating stud 42 can be extracted from a positioning hole 41, be inserted in another positioning hole 41, when locating stud 42 is inserted into the positioning hole 41 of bottommost, then the compressible distance of spring 1 is the longest, certainly, locating stud 42 also can not be inserted in positioning hole 41, now, the length of positioning rod 31 is the reduction length of spring 1.
As the preferred scheme of one, described positioning hole 41 has two rows, every registration hole 41 comprises several and to be arranged on positioning rod 31 sidewall and along the equally distributed positioning hole 41 of axis of positioning rod 31, two registration holes 41 are symmetrical along the shaft axis of positioning rod 31, locating stud 42 is inserted into two along in the positioning hole 41 of the shaft axis symmetry of positioning rod 31, that is, when locating stud 42 is inserted into positioning hole 41, locating stud 42 runs through positioning rod 31, thus locating stud 42 is horizontal, can locate more accurately on the one hand, another is convenient also can prevent from locating stud 42 to be moved when bar 32 clashes into deforming.
Cavity 30 inwall of positioning rod 31 has guiding groove 311 and this guiding groove 311 runs through the two ends of positioning rod 31, the outer wall of described movement rod 32 has gib block 321 and this gib block 321 extends to the two ends of movement rod 32 and concordant with the two ends of movement rod 32, when movement rod 32 is inserted in the cavity 30 of positioning rod 31, gib block 321 to be inserted in guiding groove 311 and gib block 321 and guiding groove 311 Spielpassung, flexible dependence gib block 321 between movement rod 32 and positioning rod 31 plays positioning action with guiding groove 311, thus prevent telescopic process medi-spring 1 from twisting, thus the axis making telescopic process of the present invention be only limited to spring 1 is carried out, thus the flexible more reliable of spring 1 is made.
As the preferred scheme of one, guiding groove 311 has two and shaft axis along positioning rod 31 is symmetrical, described gib block 321 has two and shaft axis along movement rod 32 is symmetrical, two symmetrical guiding grooves 311 make telescopic process more flexibility and reliability with coordinating of gib block 321, and namely the axial stretching of spring 1 is more reliable.
Specific embodiment described herein is only to the explanation for example of the present invention's spirit.Those skilled in the art can make various amendment or supplement or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present invention or surmount the scope that appended claims defines.
