Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of ratchet mechanism.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described in further detail.
As shown in Figure 1, the threaded rod structure of rapid adjustment length of the present invention, it is vertically mounted between the stand column and beam 11 of shale shaker, moving beam 12, stand column and beam 11 is fixed, moving beam 12 is connected with one end of vibrosieve sifting bed, moving beam 12 can move up and down and regulate vibrosieve sifting bed inclination angle, regulates rapidly the threaded rod structure of length to be positioned in the middle of stand column and beam 11, moving beam 12.As described in Figure 2, the threaded rod structure of rapid adjustment length comprises threaded rod 1, lower threaded rod 2, nut cylindrical shell 3, ratchet mechanism 4 and handle 5, upper threaded rod 1, lower threaded rod 2 front end are arranged on the two ends of nut cylindrical shell 3 with the screw-internal thread fit of nut cylindrical shell 3 respectively, and nut cylindrical shell is contrary with the thread rotary orientation that upper threaded rod 1 and lower threaded rod 2 connect.Upper threaded rod 1, the end of lower threaded rod 2 is vertically mounted on the bottom of two " U " shape parts 10 respectively, the through hole run through the left and right for installing should be had in " U " shape part 10 top, " U " shape part upper threaded rod front end installed by screw, " U " shape part that lower threaded rod 2 front end is installed is arranged on stand column and beam 11 top of shale shaker respectively, on the journal stirrup that moving beam 12 bottom is arranged, nut cylindrical shell 3 is installed ratchet mechanism 4, this ratchet mechanism 4 is installed the handle 5 that can pull up and down by bolt, when not using, handle 5 is pulled substantially parallel with nut cylindrical shell 3, pulling lower handle 5 during use makes it vertical with nut cylindrical shell 3, left and right directions rotation handle 5 promotes nut cylindrical shell 3 and rotates, upper threaded rod 1, lower threaded rod 2 revolves entry/exit nut cylindrical shell 3 in opposite directions, thus make moving beam 12 to move or reduces, regulate vibrosieve sifting bed inclination angle.Due to be two threaded rods relative to nut cylindrical shell 3 move toward one another, make rising or falling speed fast, this device is Purely mechanical structure, and structure is simple, and supporting capacity is strong, and not fragile, long service life, cost is little.
As shown in Figure 2, ratchet mechanism 4 is two-way external toothing formula, comprise double-deck parallel mounting plates 6, ratchet 7 and changement 8, parallel mounting plates 6 all has the through hole run through up and down, the through hole that nut cylindrical shell 3 runs through through parallel mounting plates about 6 and both matched in clearance, ratchet 7 is positioned between double-deck parallel mounting plates 6, the through hole run through is had in the middle part of ratchet 7, this nut cylindrical shell 3 passes this ratchet 7 middle through-hole and both interference fit, between parallel mounting plates 6 upper and lower plates, rotating shaft is installed, this rotating shaft is provided with two-way ratchet 9, the end of this ratchet 9 is the commutation driving lever for commutating that the one of stretching out connects, two-way ratchet 9 and commutation driving lever form changement 8 jointly.Transmission is carried out in the most advanced and sophisticated teeth groove for snapping in ratchet 7 respectively of two ratchets of ratchet 9; Parallel mounting plates 6 is also provided with front end and withstands on fore-set on ratchet 9, the front end of this fore-set is perpendicular to the rotating shaft between parallel mounting plates 6 upper and lower plates, and rear end is connected with Compress Spring.A ratchet tip of ratchet 9 snaps in the teeth groove of ratchet 7, pull lower handle downwards, left and right directions manually pulls handle 5, nut cylindrical shell 3 is driven to rotate by ratchet 7, upper threaded rod 1, lower threaded rod 2 be relative relative to nut cylindrical shell 3/move toward one another, thus make moving beam 12 reduce or raise, due to spring has been installed in bottom fore-set effect under handle can return after continue equidirectional pulling again, easy to operate.Stir commutation driving lever, above-mentioned ratchet tip is separated with the teeth groove of ratchet 7, another ratchet tip of ratchet 9 snaps in the teeth groove of ratchet 7, manually pull handle 5, nut cylindrical shell 3 opposite spin is driven by ratchet 7, upper threaded rod 1, lower threaded rod 2 relative to nut cylindrical shell 3 in opposite directions/relative motion, thus make moving beam 12 raise or reduce.
This regulates rapidly threaded rod structural entity of length to adopt all steel material, and not only attractive in appearance, anticorrosive and easy to operate, compact conformation is practical, not fragile, produce and use cost all little.
The above embodiment of the present invention is only for example of the present invention is described, and is not the restriction to embodiments of the present invention.For those of ordinary skill in the field, other multi-form change and variations can also be made on the basis of the above description.Here cannot give exhaustive to all embodiments.Every belong to technical scheme of the present invention the apparent change of amplifying out or variation be still in the row of protection scope of the present invention.
