Abstract
The utility model provides a shear type jack belonging to lifting device, which comprises a plug, a couple of upper frames, a couple of lower frames, a lead screw and a base. The utility model is characterized in that an upper frame and a relative lower frame are connected via a fixing casing, and an extension nut connected with the lead screw is fixed on the fixing casing. The shear type jack has the advantages of simple structure and simple production, which arranges an extension nut to replace general nut to shorten the lead screw, reduce the deformation rate of lead screw and realizing limit function when the jack is at high position, to save storage space and make structure compact.
Description
Technical field
The utility model relates to a kind of lifting gear, especially a kind of scissors-type jack.
Background technology
Scissors-type jack is an a kind of important hoisting device that is widely used in load-carrying vehicle or mobile device upper support equipment self-weight, adjusts equipment level, and the departments such as factories and miness, communications and transportation that are mainly used in are as work such as Mechanical Help and other lifting, supports.It utilizes rigid top to lift part as equipment, the light little weight-lifting equipment of jacking weight in little stroke by top or bottom.On traditional scissors-type jack, the screw thread that cooperates with screw mandrel all be design on fixed cover, the length of the screw mandrel that so just makes must very long (as Fig. 1), thereby is difficult to guarantee the right alignment of screw mandrel, causes screw mandrel the phenomenon of bending to occur easily.And when scissors-type jack is packed up,, must occupy bigger space and deposit, very inconvenience because screw mandrel is very long.
Summary of the invention
1, goal of the invention: in order to solve the existing deficiency of scissors-type jack on said structure, the utility model provides a kind of scissors-type jack, this scissors-type jack extends nut replacement plain nut by installing, thereby reduced the length of screw mandrel, make screw mandrel distortion probability significantly reduce, and also saved its parking space.
2, technical scheme: a kind of scissors-type jack described in the utility model, it comprises a pair of upper bracket, a pair of lower bracket and screw mandrel, it is characterized in that: a cooresponding upper bracket is connected by fixed cover with a lower bracket, and the extension nut that links to each other with screw mandrel is fixed on the fixed cover.
In order effectively to promote weight, screw mandrel is connected with the negative thread that extends nut.
For will extend that nut is fixed on the scissors-type jack and with the effective cooperating of screw mandrel, the fixed cover that connects upper bracket and lower bracket is enclosed within and extends on the nut body, extends nut bottom and fixed cover flange and rivets.
For more firm securing elongated nut, extend nut body and be welded on the fixed cover.
For will extend that nut is fixed on the scissors-type jack and with the effective cooperating of screw mandrel, the fixed cover that perhaps will connect upper bracket and lower bracket is enclosed within on the extension nut body that is provided with step, fixed cover contacts with step, extends the riveted joint of nut bottom and fixed cover flange.
The utility model mechanical work principle is: the screw thread that utilization extension nut will cooperate with screw mandrel on the basis that guarantees the scissors-type jack rigidity and the distance of screw mandrel shorten, thereby actv. has shortened the length of screw mandrel itself, have reduced screw mandrel distortion probability.
3, beneficial effect: the utility model is simple in structure, realize easily, extend nut replacement plain nut by installing, thereby reduced the length of screw mandrel, make screw mandrel distortion probability significantly reduce, can also device when scissors-type jack is raised to the higher position to position-limiting action, saved its parking space greatly, make the structure of jack itself more compact.

The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 2, this scissors-type jack comprises top 1, upper bracket 2, lower bracket 3, fixed cover 4, screw mandrel 5, base 6 and extends nut 7.
Embodiment 1
Two upper brackets, 2 one ends are installed in respectively on the top 1 and are meshing mutually, and the other end connects lower bracket 3 one ends by two anchor fittings respectively, and two lower brackets, 3 other ends are installed on the base 6 and are meshing mutually.There is one to be fixed cover 4 in two anchor fittings, fixed cover 4 is enclosed within and extends on nut 7 bodies, and weld (as Fig. 4) mutually with extension nut 7 bodies, extend nut 7 front ends and be provided with negative thread, stretch out extension nut 7 bottoms and the fixed cover flange riveted joint (as Fig. 3) of fixed cover 4, extend nut 7 like this and just be fixed on the fixed cover 4 firmly.Be provided with externally threaded screw mandrel 5 one ends and be installed on another anchor fitting, the other end links to each other with screw thread with cooresponding extension nut 7 front ends.When the needs scissors-type jack is worked, handle by instrument rotary screw rod 5, since screw mandrel 5 with extend nut 7 and link to each other with negative thread, extend nut 7 firm being fixed on the fixed cover 4, so screw mandrel 5 just precession extends in the nut 7 (as Fig. 6), thereby make scissors-type jack shorten, because equilibrium of forces in horizontal distance, make the scissors-type jack longitudinal travel increase, raise, play the effect of lifting.When extension nut 7 contacted with the anchor fitting that screw mandrel 5 is installed, promptly jack vertically raise and reaches maximum height.After finishing using, counter-rotation screw mandrel 5 handles, scissors-type jack increases in horizontal distance like this, because equilibrium of forces makes the scissors-type jack longitudinal travel reduce, reduce, finally is retracted to initial condition.Compare owing to reduced the length of screw mandrel with original scissors-type jack, make screw mandrel distortion probability reduce greatly, and also saved its parking space, thereby make the structure of jack itself more compact.
Embodiment 2
Two upper brackets, 2 one ends are installed in respectively on the top 1 and are meshing mutually, and the other end connects lower bracket 3 one ends by two anchor fittings respectively, and two lower brackets, 3 other ends are installed on the base 6 and are meshing mutually.There is one to be fixed cover 4 in two anchor fittings, fixed cover 4 is enclosed within on extension nut 7 bodies that are provided with step, and contact with step or mutually by (as Fig. 5), extend nut 7 front ends and be provided with negative thread, stretch out extension nut 7 bottoms and the fixed cover 4 flange riveted joints (as Fig. 3) of fixed cover 4, extend nut 7 like this and just be fixed on the fixed cover 4 firmly.Be provided with externally threaded screw mandrel 5 one ends and be installed on another anchor fitting, the other end links to each other with screw thread with cooresponding extension nut 7 front ends.When the needs scissors-type jack is worked, by instrument rotary screw rod 5 handles, since screw mandrel 5 with extend nut 7 and link to each other with negative thread, extend nut 7 firm being fixed on the fixed cover 4, so screw mandrel 5 just precession extends in the nut 7 (as Fig. 7), thereby make scissors-type jack shorten, because equilibrium of forces in horizontal distance, make the scissors-type jack longitudinal travel increase, raise, play the effect of lifting.When extension nut 7 contacted with the anchor fitting that screw mandrel 5 is installed, promptly jack vertically raise and reaches maximum height.After finishing using, counter-rotation screw mandrel 5 handles, scissors-type jack increases in horizontal distance like this, because equilibrium of forces makes the scissors-type jack longitudinal travel reduce, reduce, finally is retracted to initial condition.Compare owing to reduced the length of screw mandrel with original scissors-type jack, make screw mandrel distortion probability reduce greatly, and also saved its parking space, thereby make the structure of jack itself more compact.
