Specific embodiment
In order to more clearly state the utility model, the utility model is further described with reference to the accompanying drawing.
Referring to Fig. 1, the utility model discloses a kind of hand-rail type ratchet elevator, including chassis 1, support rod 2 and work
Make platform 3, the both ends connection chassis 1 and workbench 3 of support rod 2, support rod 2 is equipped with two, including first support bar 21 and second
Support rod 22, first support bar 21 and 22 misfit of second support bar link together, and are carried out hingedly using ratchet assembly 6；Second
Support rod 22 is equipped with gear grooved 221, and gear grooved 221 is meshed with the gear in ratchet assembly 6, thus in ratchet assembly 6
Under drive, the up and down motion of the second moving lever 22 is realized, workbench 3 is driven to be risen or fallen, in the present embodiment, use
The gear of ratchet assembly drives support rod to move up and down, since the distance between groove body adjacent in gear grooved is identical
, so the distance moved every time is all identical during being risen or fallen, therefore when movement more
Steadily, it can be realized and stop under arbitrary height, meet actual use demand.
In order to achieve the above technical purposes, the middle part of first support bar 21 is provided with concave part, in second support bar 22
Portion is equipped with lug boss, and lug boss surface is equipped with gear grooved 221, and the opening both ends activity of concave part is clamped lug boss, so that
Second support bar 22 moves up and down under the limitation of first support bar 21, by the way of socket, so that second support bar
During exercise always in the control range in first support bar；One side first support bar protects gear grooved, another
Aspect groove and protrusion cooperation so that the gear in ratchet assembly engaged with gear grooved it is more stable so that workbench into
More safety and stability during row raising and lowering.
Ratchet assembly 6 includes gear-box 61 and rocking handle 62, is equipped with multiple gears in gear-box 61, including rotate gear 63,
Transmission gear and movement gear 64, rocking handle 62 are arranged in the outside of gear-box 61, are fixedly connected with rotate gear 63, rotate gear
63 engage with transmission gear, and transmission gear is engaged with movement gear 64, move the gear grooved 221 of gear 64 and second support bar 22
It is connected together；Transmission gear includes the first transmission gear 65 and the second transmission gear 66, the first transmission gear 65 and turning gear
Wheel 63 is meshed, and the second transmission gear 66 is engaged with movement gear 64；First transmission gear 65 and the second transmission gear 66 use
Vertical engagement.In a particular embodiment, there are two the first transmission gear is set, by the mutual cooperation between gear, to realize use
The power of very little can realize that gear rotates；Second transmission gear is designed as vertical structure, can effectively be changed so entire
The transmission direction of gear finally enables movement gear to stablize and is clamped in the gear grooved of second support bar.
Ratchet 67 and brake block 68 are additionally provided with by rotate gear 63, brake block 68 is socketed in rotation locating for rotate gear 63
