Abstract
A stepless lifting device belongs to the field of operation machinery, and is particularly suitable for lifting a vehicle driving seat. It is made up of mechanical structure, and is operated by telescopic and automatic-retracting handle, so that it is convenient and labour-saving. The device is a four-fulcrum double-parallelogram mechanism, can synchronously lift, is stable and reliable, can stop at any position in the designed maximum lifting range and automatically lock, is easy to change the lifting range, and is an ideal device for mounting the drivers' seats of automobiles and similar vehicles.
Description
The utility model relates to a kind of stepless jacking system, belongs to Work machine, is applicable to the installation driving seat.
The lifting of existing driving seat, all there is shortcoming in general single group gear ﹠ rack structure or the single hydraulic ram structure of adopting.Adopt single group gear ﹠ rack structure, the descending operation trouble, and wave easily after raising, poor stability is used single hydraulic ram, though easy to operate, there is instability problem equally.If make it stable, must take turns tooth bar or a plurality of hydraulic ram structure with multiple sets of teeth, make complexity, the cost height.
It is rapid that the purpose of this utility model provides a kind of lifting, reliable, easy to operate, laborsaving, make simply, but the jacking system of stepless lifting and self-locking, to overcome the deficiency of existing jacking system.
Through applicant's retrieval, it is open to find no same apparatus.
The utility model can be achieved through the following technical solutions: form stepless jacking system by bright, the enclosing cover of combination hand, dial, lock collar, backing plate, dowel disc, gear, drive link, preceding rocking bar, back rocking bar, connecting rod, elevating arc, stirrup, front-axle beam, the back rest, steel ball, locking spring, torsion spring, bearing, pin etc.Rocking bar, two back rocking bars, two connecting rods constitute two parallel-crank mechanisms before two, handle and enclosing cover relative fixed, and dial is fixed on outer covering, and can relatively rotate around gear wheel shaft; Lock collar is installed on the rack and can not relatively rotates, and opens two breach on the lock collar, is used to install locking spring and steel ball, and steel ball and locking spring are spacing by backing plate, dowel disc and dial, can not come off; Dowel disc is fixed on the seat matrix; Two pusher dogs of dial are stretched in the groove of lock collar; Gear wheel shaft is connected with drive link and can not relatively rotates, and the other end of drive link is connected with same gear; Torsion spring is housed on the drive link, and torsion spring one end is fixed on the drive link, and the other end is used to offset the body weight of chaufeur, and alleviates the operation resistance; Rocking bar relative fixed before two elevating arcs and two, back rocking bar links to each other with preceding rocking bar by connecting rod, and forward and backward rocking bar can rotate around fulcrum separately, and fulcrum is made up of bearing and pin, and pin is contained on the bearing; Gear and elevating arc remain engagement, can not break away from; The front-axle beam and the back rest are used for fixing bearing; Stirrup is connected with two back rocking bars, plays booster action; Combination handle is the more piece Collapsible structure, and auto retractable is so that easy to operate, laborsaving.When the needs lifting, pull out and on carry or press down combination handle, just can drive dial one pusher dog by enclosing cover and dial loose steel ball, another pusher dog is stirred the lock collar rotation simultaneously, the lock collar driven gear rotates, gear promptly drives elevating arc and rotates, since relative fixed between elevating arc and preceding rocking bar, and gear and elevating arc maintenance engagement, and dowel disc has limited the possibility of gear rolls downward, so preceding rocking bar promptly rotates around fulcrum, rocking bar drives the back rocking bar by connecting rod and rotates simultaneously, just realizes stepless lifting, when being elevated to correct position and not needing in lifting, decontrol handle, steel ball is by the locking spring auto lock.The adjustable height scope can design the rocking bar of different length as required.
The drawing of accompanying drawing is described as follows;
Fig. 1 is the front view of the stepless jacking system of the utility model;
Fig. 2 is that the A of Fig. 1 is to view;
Fig. 3 is the B-B cutaway view of Fig. 2.
Below in conjunction with a description of drawings embodiment of the present utility model: rocking bars 13, two back rocking bars 1, two connecting rods 6 before two among the figure, constitute two parallel-crank mechanisms (only drawing among the figure one), the shell of combination handle 9 and enclosing cover 7 welding, dial 21 is screwed on enclosing cover 7 and can rotates around gear wheel shaft 24 together, and link to each other with gear wheel shaft 24 ends with packing ring 23 with screw 22, prevent to come off; Lock collar 20 is installed on the square step of gear wheel shaft 24 by the square hole of centre, have two breach 28 on the lock collar 20, be used to install locking spring 29 and steel ball 30, the pusher dog 26 of dial is stretched in the breach 28 of lock collar, and locking spring 29 and steel ball 30 limits are in the groove that backing plate 19, dowel disc 8, dial 21 and breach 28 are formed; Village's cover 25 is used to adjust the position; Drive link 18 is welded on the gear wheel shaft 24, and the other end of drive link 18 also is equipped with gear 11; Torsion spring 17 1 ends are fixed on the drive link 18 by bolt 15 and nut 16, and the other end leans against the seat matrix 10 times, to offset chaufeur gravity, alleviate the operation resistance; Rocking bar 13 is fixing by rivet 27 before two elevating arcs 12 and two, and back rocking bar 1 links to each other with preceding rocking bar 13 by connecting rod 6, and forward and backward rocking bar can be around fulcrum rotation separately, and the pin 4 of fulcrum is installed on the bearing 3, and four bearings 3 are separately fixed on the front-axle beam 14 and the back rest 5; Gear 17 and the restriction of elevating arc 12 by seat matrix 10 remain engagement; Stirrup 2 is welded on the two back rocking bars 1, plays booster action; Combination handle 9 adopts the more piece flexible springs formula structure of withdrawing automatically, can pull out during operation, so that laborsaving.When the needs lifting, pull out on combination handle 9 backs and carry or press down, handle casing drives dial 21 by enclosing cover 7,26 groups of loose steel balls 30 of a pusher dog of dial 21, another pusher dog drives lock collar 20 rotations simultaneously, lock collar 20 is rotated by gear wheel shaft 24 driven gears 11, and gear 11 drives elevating arc 12 again and rotates, because the constraint of condition, preceding rocking bar 13 can only rotate around fulcrum, rocking bar 1 rotated after rocking bar 13 drove by connecting rod 6 simultaneously, so whole seat matrix is together with the parallel-crank mechanism lifting, after being elevated to correct position, decontrol handle, handle is withdrawal automatically just, and steel ball is realized stepless lifting by the effect auto lock of locking spring simultaneously.
The utility model stepless elevating means for tables has the following advantages than existing lowering or hoisting gear:
1 all adopts frame for movement, and lifting is reliable, rapidly, makes simple, easy to operate, laborsaving.
Self-locking is realized in any position that can rest on during 2 lifting in the design maximum height scope, and steadily, does not wave in the course of work.
