Abstract
The utility model relates to a sidespin jack, belonging to a lifting device. The utility model mainly solves a problem that a turning handle of a jack is difficult to operate in a small space. The utility model comprises a base and a lifting device arranged on the base. The lifting device mainly consists of a sleeve and a bolt, and a shaft sleeve matching the bolt is arranged in the sleeve. A top pad is arranged on a top end of the bolt. The utility model is characterized in that a worm wheel is arranged on the bolt in the same shaft and the threads of worm wheel match the threads of the bolt; the worm wheel is arranged above the sleeve and a push bearing is arranged between a bottom face of the worm wheel and a top face of the sleeve. A press cover is arranged above the worm wheel, and the press cover is fixedly connected with the sleeve, and a push bearing is arranged between a top face of the worm wheel and a bottom face of the press cover. Two ends of the bolt matching the worm wheel are arranged on a support seat through a bearing, and the support seat is fixedly connected with the sleeve, and a turning handle is arranged at an end part of the worm. The operation of the turning handle is free from a space limit, and the operation is convenient.
Description
Technical field
The utility model relates to a kind of jacking system, especially the mechanical type jack.
Background technology
At present, sleeve that the mechanical type jack is solidly installed by base, with base and the screw rod that is arranged in the sleeve are formed, be provided with the axle sleeve that cooperates with screw rod in the sleeve, axle sleeve is provided with short of level or through hole, during work, move short or the hank thick stick is inserted in the horizontal through hole, rotate then short or the strand thick stick axle sleeve is rotated relative to screw rod, screw rod vertically moves, thus screw rod is risen and the top pad by screw tip with object jack-up.If in narrower space or the narrow space of depth, rotate the strand thick stick and can be subjected to space constraint, the strand thick stick can only rotate by low-angle, operates very inconvenient.
The utility model content
In order to overcome the shortcoming that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of easy to operate sideswinging type jack.
The technical solution of the utility model is: the sideswinging type jack, comprise base and be installed in jacking system on the base, jacking system mainly is made up of sleeve, screw rod, be provided with the axle sleeve that cooperates with screw rod in the sleeve, the top of screw rod is provided with the top pad, it is characterized in that: on the described screw rod with axle mounting one worm gear, screw thread fit between worm gear and the screw rod, worm gear is positioned at the sleeve top, and between the bottom surface of worm gear and sleeve end face thrust baring is installed, the worm gear top is provided with a gland, and gland and sleeve are affixed, are provided with thrust baring between worm gear end face and the gland bottom surface; The worm screw two ends that cooperate with worm gear by bearing installation on bearing, the affixed sleeve of bearing, the worm screw end is provided with a turning handle.
As further technical scheme of the present utility model: the end of worm screw is provided with a jack vertically, and turning handle one end is provided with the inserted link that cooperates with jack.
During use, the handle of rotary worm end, worm screw is rotated, the worm drive worm gear, the worm gear drives screw rod rotates, and finally makes the top pad of screw tip with object jack-up thereby screw rod is risen.
The beneficial effects of the utility model are: it is not subjected to space constraint because turning handle is arranged on the worm screw end, and worm screw plays horizontally extending effect, and turning handle is in outside the object bottom surface when making work when turning handle is operated like this, has made things convenient for operation; The result of use ideal, and simple in structure, easily make.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment,
Fig. 2 is the right elevation of the utility model embodiment,
Among the figure: 1 base, 2 sleeves, 3 screw rods, 4 top pads, 5 worm gears, 6 worm screws, 7 glands, 8 thrust barings, 9 handles, 10 bearings.
The specific embodiment
As shown in Figure 1 and Figure 2.
This sideswinging type jack, comprise base 1 and be installed in jacking system on the base, jacking system mainly is made up of sleeve 2, screw rod 3, be provided with the axle sleeve that cooperates with screw rod in the sleeve 2, the top of screw rod 3 is provided with top pad 4, on the described screw rod 3 with axle mounting one worm gear 5, screw thread fit between worm gear 5 and the screw rod 3, worm gear 5 is positioned at sleeve 2 tops, and between the bottom surface of worm gear 5 and sleeve 2 end faces thrust baring 8 is installed, worm gear 5 tops are provided with a gland 7, and gland 7 is affixed by the attaching parts bolt with sleeve, also is provided with thrust baring between worm gear 5 end faces and gland 7 bottom surfaces; Worm screw 6 two ends that cooperate with worm gear by bearing installation on bearing 10, bearing 10 affixed sleeves, also can with the sleeve integral structure, worm screw 6 ends are provided with a jack vertically, handle 9 one ends are provided with the inserted link that cooperates with jack.Spliced eye can be prismatic hole, and the inserted link of Pei Heing is prismatic with it; Can also be connected by key between spliced eye and the inserted link, also can realize identical functions.
During use, turning handle is plugged in the jack, turning handle 9, worm screw 6 is rotated, and worm screw 6 drives worm gear 5 and rotates, and worm gear 5 makes screw rod 3 risings finally make the top pad 4 of screw tip with object jack-up.After hours, handle is taken off, be convenient to like this deposit, save parking space.
Claims (2)
