Abstract
The utility model relates to a miniature screw jack belonging to a miniature hoisting tool, in particular to a hack used for a tricycle and a quadricycle. The jack comprises a base, wherein, a screw is fixedly connected on the base and is connected with the lower end of a nut fixing frame through a thread, the upper end of the nut fixing frame is connected with the other screw through a thread, an upper fork is fixedly connected at the upper end of the screw connected with the upper end of the nut fixing frame, and the spiral directions of the screw threads of the two screws are opposite. Due to the design, the base is supported on the ground, the upper fork is clipped on the girder of a vehicle; when the nut fixing frame rotates, the two screws move back to back and stretch towards the both ends, so that the vehicle is jacked up; and when the nut fixing frame rotates in the opposite direction, the two screws oppositely move, so that the vehicle is descended. The utility model has the advantages of compact structure, simple operation, security and reliability.
Description
Technical field
The utility model relates to a kind of small-sized lifting gear, relates in particular to the jack of three-wheel vehicle, four-wheeled use.
Background technology
The application of jack is very extensive, needs repairing or during changing of tire, uses jack with vehicle jack-up usually as three-wheel vehicle, four-wheeled, and operate the below that enters vehicle then.At present general jack adopts vapour-pressure type or fluid pressure type structure, has complex structure, shortcomings such as inconvenient operation.Also have the shaking jack in addition, but this jack need be realized the lifting of jack by shaking handle, time-consuming effort again, inefficiency, manufacturing cost height.
The utility model content
The purpose of this utility model is in order to overcome the deficiencies in the prior art, a kind of simple in structure, easy to operate miniature screw jack to be provided.
The purpose of this utility model is achieved in that miniature screw jack, comprise base, captive joint screw rod on the base, screw rod is threaded with the lower end of nut fixed mount, the upper end of nut fixed mount is connected with another screw flight, pitch on captiveing joint with bonded assembly screw rod upper end on the nut fixed mount, the thread hand of spiral of described two screw rods is opposite.
The utility model is by above design, and with base support on the ground, last fork is on the crossbeam of vehicle, and when the rotating nut fixed mount, two screw rods move dorsad, to two elongation, thereby with vehicle jack-up.Opposite sense rotating nut fixed mount, two screw rods move in opposite directions, thereby vehicle is reduced.The utility model compact conformation, simple to operate, volume is little, and is safe and reliable.Be applicable to that small tricycle, four-wheeled are repaired, changing of tire.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, miniature screw jack comprises base 5, the positive tooth screw rod 4 of captive joint on the base 5, positive tooth screw rod 4 is threaded with the lower end of nut fixed mount 3, and the upper end of nut fixed mount 3 is threaded with anti-tooth screw rod 2, pitches 1 on the captive joint on the anti-tooth screw rod 2.
Claims (1)
1, miniature screw jack, it is characterized in that: comprise base, captive joint screw rod on the base, screw rod is threaded with the lower end of nut fixed mount, the upper end of nut fixed mount is connected with another screw flight, pitch on captiveing joint with bonded assembly screw rod upper end on the nut fixed mount, the thread hand of spiral of described two screw rods is opposite.
