Abstract
The utility model discloses a lifting structure. The lifting structure comprises liftable upper and lower supporting legs, wherein the upper and lower supporting legs are provided with the lifting structure. As an improvement of the lifting structure, the lifting structure comprises a pushing and lifting rod which drives one supporting leg to lift up relative to the other supporting leg, a gear which is arranged on one supporting leg, a lifting rack which is engaged with the gear and is arranged on the other supporting leg, and a lifting and locating device, wherein the gear is connected with a drive rod. According to the lifting structure, the pushing and lifting rod which pushes the supporting leg to lift up and down, the lifting rack and the gear are arranged on the lifting structure, so that a support can be conveniently and easily lifted up; the lifting and locating device is arranged on a brake wheel matched with the gear, and the support can be reliably located by a brake plate; and the releasing handle of the lifting device can be conveniently and quickly released and located, so that the support frame is lifted up. The lifting structure is simple in structure, convenient to lift up and down and reliable to locate.

The specific embodiment
Referring to Fig. 1-6, the implementation case comprise liftable on, lower support leg 1,2, on, lower support leg 1,2 are provided with lifting structure, lifting structure comprises that driving a supporting leg raises bar 3 with respect to what another supporting leg rose, be arranged at the gear 21 on the lower support leg 2, be arranged at the lifter rack 11 that meshes with gear 21 on the upper support leg 1, lifting-positioning device, be connected with drive link 4 on the gear 21, lifting-positioning device comprises the braked wheel 41 that is connected on the drive link 4, the keep plate 42 that cooperates with set teeth groove on the braked wheel 41, handle 5 is removed in the braking of keep plate 42, the framework of positioning driving wheel 41 and keep plate 42, keep plate 42 are provided with and keep keep plate 42 to cooperate the back-moving spring of braking braked wheel 41 with teeth groove.
For the ease of using and preventing that keep plate 42 from coming to nothing, keep plate 42 is provided with and cooperates brake portion and vacancy part with braked wheel 41, brake portion matches with the teeth groove of braked wheel 41 can brake braked wheel 41, and vacancy partly is positioned at braked wheel 41 places, and braked wheel 41 is not braked.
For the ease of using, remove handle 5 and directly be provided with brake cable 51 with keep plate 42, further preferred, be hinged with a crank drive plate 43 on the keep plate 42, crank drive plate 43 constitutes to drive the lever that keep plate 42 slides, and crank drive plate 43 is connected by brake cable 51 with releasing handle 5.
Wherein, raise bar 3 and be air spring, upper and lower supporting leg 1,2 is the inside and outside supporting leg of socket.
When the utility model product uses, remove handle 5 by moving, the vacancy part of keep plate 42 is matched with the teeth groove of braked wheel 41, braked wheel 41 is not braked, raise the driving upper support leg 1 of bar 3, rise by upgrading tooth bar 11 with respect to lower support leg 2, rise to suitable height and decontrol releasing handle 5, keep plate 42 resets, brake portion matches with teeth groove, braked wheel 41 brakings, the gear 21 that is connected in drive link 4 other ends drives lifter rack 11 brakings, upper and lower supporting leg 1,2 relative positionings.Also can before resetting, keep plate 42 manually push upper support leg 2 down to suitable height, decontrol again and remove handle 5, keep plate 42 resets, brake portion matches with teeth groove, braked wheel 41 brakings, the gear 21 that is connected in drive link 4 other ends drives lifter rack 11 brakings, upper and lower supporting leg 1,2 relative positionings.
