Abstract
A height-adjusting device of a lifting support comprises the lifting support, a fixing support and a lifting device. The fixing support is a hollow square steel tube, and the square lifting support is sleeved with the fixing support; the lifting device is composed of a gear and a rotary hand wheel which is fixed to the gear, and the gear is fixed to the fixing support; a gear rack engaged with the gear is arranged on one side of the lifting support, a corresponding rectangular opening is formed in the same side of the fixing support, and the gear is engaged with the gear rack on the lifting support through the rectangular opening in the fixing support; the rotary hand wheel rotates to drive the gear to rotate and push the lifting support to ascend and descend. Gear transmission is used for ascending and descending operation of the lifting support; meanwhile, a locking device is additionally arranged, and therefore the stability and durability of the height-adjusting device are guaranteed; the structure is simple, and operation is easy and convenient.
Description
Technical field
The present invention relates to a kind of arrangement for adjusting height of liftable support, especially a kind of arrangement for adjusting height of the liftable support suitable for hand propelled GREEB HEDGE MACHINE.
Background technology
Hedgerow is, with closely plant dense planting, to form the plant hedge of the rule combined closely by shrub or dungarunga.Hedgerow can be trimmed to various moulding, so as to improve appreciation effect, and play a part of isolating and protecting, thus hedgerow occupies critical role in urban road and afforestation., mainly by hand-held, backpack and mechanical self-propelled, still based on artificial, not only the amount of labour is big, efficiency is low, is also frequently accompanied by dangerous generation for the hedge trimming in Garden Greenland for the hedgeclipper for using at present.Hand propelled hedgeclipper is that one kind is relatively small suitable in bulk area afforestation, and the portable hedgerow Work machine with certain automaticity.Different from hand-held GREEB HEDGE MACHINE, hand propelled GREEB HEDGE MACHINE needs to arrange liftable support and be highly adjusted which, and purely manual regulation is not convenient and swift enough；Height is adjusted using motor, needs increase equipment and increased the consumption of the energy.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of arrangement for adjusting height of the liftable support suitable for hand propelled GREEB HEDGE MACHINE.
In order to solve above-mentioned technical problem, the technical scheme is that：
A kind of arrangement for adjusting height of liftable support, including liftable support, fixed support, lowering or hoisting gear；Fixed support is hollow rectangular steel tube, is sleeved on square liftable support；Lowering or hoisting gear is made up of gear and rotation hand wheel, and rotation hand wheel is fixed on gear, and gear is fixed on fixed support；There is the tooth bar agreed with gear liftable support side, and fixed support homonymy has corresponding rectangular aperture, and gear is mutually agreed with the tooth bar on liftable support by the rectangular aperture on fixed support；Rotation hand wheel is rotated, and is driven pinion rotation, and then is promoted liftable support lifting.
Present invention additionally comprises locking device, locking device is connected with fixed support loose-leaf system, liftable support side is provided with row cylindrical hole vertically, on the inside of locking device, correspondence position is provided with the cylindrical projection mutually agreed with, fixed support is provided with groove corresponding to the position of scalable support cylindrical hole, cylindrical projection on locking device is inserted by groove in the cylindrical hole on liftable support, and liftable support is compressed downwards naturally due to action of gravity, so as to play locking action.
The present invention carries out descending operation using gear drive to liftable support, while setting up locking device, it is ensured that the stability and durability of arrangement for adjusting height, simple structure, easy to operate.
Description of the drawings
Fig. 1 is the overall rearview of the present invention.
Fig. 2 is the support schematic perspective view of the present invention.
Fig. 3 is double bracket schematic diagram.
Specific embodiment
The present invention is further detailed explanation with specific embodiment below in conjunction with the accompanying drawings.Obviously, described embodiment a part of embodiment only of the invention, rather than the embodiment of whole.Based on the every other embodiment obtained on the premise of creative work is not made by the embodiment in the present invention, this area and those of ordinary skill in the related art, should all belong to the scope of protection of the invention.
A kind of arrangement for adjusting height of liftable support, as shown in figure 1, including liftable support 101, fixed support 102, lowering or hoisting gear；Fixed support 102 is hollow rectangular steel tube, is sleeved on square liftable support 101；Lowering or hoisting gear is made up of gear 104 and rotation hand wheel 105, and rotation hand wheel 105 is fixedly connected with gear 104, and gear 104 is fixed on fixed support 102；There is the tooth bar 1012 agreed with gear 101 side of liftable support, and 102 homonymy of fixed support has corresponding rectangular aperture 1022, and gear 104 is mutually agreed with the tooth bar 1012 on liftable support 101 by the rectangular aperture 1022 on fixed support 102；Rotation hand wheel 105 is rotated, and band moving gear 104 is rotated, and then promotes liftable support 101 to lift.
Preferably, present invention additionally comprises locking device 103, as shown in Figure 2, locking device 103 is connected with 102 loose-leaf system of fixed support, 101 side of liftable support is provided with row cylindrical hole 1011 vertically, 103 inner side correspondence position of locking device is provided with the cylindrical projection 1031 mutually agreed with, fixed support 102 is provided with groove 1021 corresponding to the position of scalable support cylindrical hole 1011, cylindrical projection 1031 on locking device 103 is inserted by groove 1021 in the cylindrical hole 1011 on liftable support 101, liftable support 101 is compressed downwards naturally due to action of gravity, so as to play locking action.
For the stability for ensureing the support of hand propelled GREEB HEDGE MACHINE and lift, the present invention is adopted and is symmetrical arranged, as shown in Figure 3, by the first liftable support 201, first fixed support 301, first locking device 401 and the second liftable support 202, second fixed support 302, second locking device 402, unified lowering or hoisting gear is by first gear 501, second gear 502, 3rd gear 503, 4th gear 504 and rotary handle 105 are constituted, rotary handle is fixed on the 3rd gear 503, first gear 501, second gear 502, 3rd gear 503, 4th gear 504 is each attached on fixed support.Rotary handle 105 is rotated clockwise, the 3rd gear 503 is rotated clockwise with rotary handle 105, adjacent second gear 502 and the 4th gear 504 are rotated counterclockwise, first gear 501 is under the drive of second gear 502 along indicators turn.Under the drive of first gear 501 and the 4th gear 504,202 lifting upwards simultaneously of the first liftable support 201 and the second liftable support；Contrary, rotary handle 105 is rotated counterclockwise, the first liftable support 201 and the second liftable support 202 decline simultaneously upwards.After by altitude mixture control to the position for needing, height is locked using locking device.
