Abstract
The invention discloses an electric single arm jack which comprises a bearing arm that is connected with a head seat, a head that is riveted with the head seat, an electric reducing mechanism that is fixed on the seat and a screw rod that is matched and connected with the reducing mechanism; the electric single arm jack is characterized in that the middle part of the bearing arm is movably assembled at the upper end of a support frame by a set pin shaft of the bearing arm; the lower end of the bearing arm is connected with a sliding pin shaft of the screw rod by a set lower shaft bolt; the lower end of the support frame is movably assembled on the electric reducing mechanism by the set lower shaft bolt. The electric single arm jack can use the direct current power supply of a car to supply the power, with convenient use and high working efficiency; the head can make circular movement or inclined movement at any position on the head seat; when the jacked object drifts, the head can carry out tracking movement in a certain range; due to the single arm structure, the jack can not be damaged, with reliable work and low cost.
Description
Technical field
The present invention relates to jack, particularly a kind of electric single arm jack.
Background technology
At present, can be divided into manual type and electrodynamic type two classes with the automobile-used jack of car configuration, use more manual type owing to needing manpower to shake, use lightly inadequately, work efficiency is lower; Electronic jack utilizes power drives, as publication number is in the patent of CN2377240 " electric-hand driven two-purpose jack ", adopt such scheme: will be embedded in the hollow actuating lever and the drive link bolt that support in the shell, make actuating lever to move up and down and can not relatively rotate along drive link, drive link is driven and is rotated by turbine worm mechanism, the input end of scroll bar then passes through the connection latch and the DC machine of conveniently assemble and disassemble, utilize the direct supply drive motor of automobile, realize electronic lifting, but this structure is carried out axle with latch and is connected, it is unreliable to work together, inconvenient operation.In addition, though existing scissors-type jack is good by the doube bridge arm mode up and down balance system of joining,,, the engagement position of causing doube bridge by permanent damage, can not re-use jack, so has been subjected to certain restriction in the use in case the jack-up thing drifts about; In addition, double-arm jack structure is complicated, and cost is higher.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, and provide a kind of simple in structure, easy to use, reliable operation, jack-up thing that drift takes place even the overturning jack does not all have damage, the electric single arm jack that can effectively increase the service life.
Purpose of the present invention is achieved through the following technical solutions:
A kind of electric single arm jack, comprise and top headstock bonded assembly loading arm, top, the screw rod that is fixed on the electric reducer structure on the base and connects with speed reduction gearing with the top headstock riveted joint, unlike the prior art be: loading arm middle part is fitted in the upper end of bracing frame versatilely by bearing pin in the loading arm that is being provided with, the lower end of loading arm is by the lower shaft bolted connection screw rod slidiing pin that is provided with, and the lower end of bracing frame is fitted on the electric reducer structure versatilely by the following axle bolt that is being provided with.
The sidepiece of described top headstock lower end sidepiece and bracing frame upper end is respectively arranged with balanced connecting rod, and balanced connecting rod makes loading arm come directly towards all maintenance levels in lifting arbitrary height position; The top is a circular arc camber with the contact surface that top headstock is complementary.
The electric reducer structure can be arranged in the casing of band overcoat.
During work, can use the DC power supply of automobile, the electric reducer structure drives the screw rod rotation, makes traveling nut move the drive loading arm on screw rod and moves, the moving top headstock of loading arm and hold-down arm matching with moving belt is made straight-line motion up and down, and top headstock rises or descends with the loading arm straight line.Set balanced connecting rod spurs top headstock moving up and down of top headstock in the process, make it keep parallel with base plane.
Advantage of the present invention is: can use the DC power supply of automobile, and easy to use, high efficiency; The structure of jack is a single arm type, and the contact surface that top and top headstock are complementary is a circular arc camber, circumference or the optional position inclination activity in the certain limit can be done in the top on top headstock, when drift takes place in the jack-up thing, the top can be followed mobile within the specific limits, the structure of single arm type makes jack can not be damaged reliable operation; Lack than double-arm structure and to have used one group of hold-down arm and loading arm, cost is lower.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Among the figure: 1. come directly towards 6. times axle bolts of bearing pin 5. bracing frames, 7. speed reduction gearing seats, 8. top headstock trammel beam bearing pins, 9. balanced connecting rods, 10. balanced connecting rod bearing pins, 11. screw rod slidiing pins, 12. screw rods, 13. electric reducer structures, 14. bases, 15. loading arms in 2. top headstocks, 3. loading arm upper pins, 4. loading arms
The specific embodiment
Below in conjunction with drawings and Examples content of the present invention is further elaborated.
Embodiment:
With reference to Fig. 1, the present invention mainly is made up of top 1, top headstock 2, bracing frame 5, balanced connecting rod 10, electric reducer structure 13, base 14, loading arm 15, top 1 and top headstock 2 contact surface matchingly are arranged to circular arc camber, top 1 is riveted on the top headstock 2 versatilely, and circumference and optional position inclination activity can be done in top 1 on top headstock 2; Top headstock 2 side centre holes are rotatably mounted to the end of loading arm 15 through loading arm upper pin 3, the middle part of loading arm 15 is fitted in the end of bracing frame 5 rotationally by bearing pin in the loading arm 4, the other end of bracing frame 5 is fitted on the speed reduction gearing seat 7 rotationally by following axle bolt 6, the side end of top headstock 2 is by in succession the rotationally end of balanced connecting rod 9 of top headstock trammel beam bearing pin 8, and the other end of balanced connecting rod 9 is connected on the bracing frame 5 rotationally by balanced connecting rod bearing pin 10; The other end of loading arm 15 is enclosed within on the screw rod slidiing pin 11 rotatable, and the side through hole connecting screw rod 12 of screw rod slidiing pin 11, screw rod 12 rotate drive screw rod slidiing pin 11 and move, and screw rod 12 ends connect electric reducer structure 13; Electric reducer structure 13 is fixed on the base 14, and base 14 upright sides are provided with sliding tray, and screw rod slidiing pin 11 is enclosed within the sliding tray.When 12 runnings of electric reducer structure 13 interlock screw rods, then driving screw rod slidiing pin 11 moves, loading arm 15 moved by screw rod slidiing pin 11 and the end that makes loading arm 15 with the effect of bracing frame 5 in the displacement of linearly rising of the base plane with respect to base 14, its end side centre hole is connected with top headstock 2 through loading arm upper pin 3, the side end of top headstock 2 balanced connecting rod 9 of ining succession, when the displacement of the end of loading arm 15 makes the variable angle of end of loading arm 15 middle parts and bracing frame 5, its balanced connecting rod 9 drives top headstock 2 under variable angle side end moves realization top headstock 2 in the vertical parallel with respect to any adjustable height of the base plane of base 14 position.
