Abstract
The invention relates to multifunctional comprehensive development and utilization of automobile maintenance and repair tools and common tools, in particular to an on-vehicle multifunctional jack, belonging to automobile maintenance works. According to the on-vehicle multifunctional jack, a worm rod is used as a driving piece and a worm wheel is used as a driven piece according to the basic principles of larger worm rod transmission rate and equivalent friction angle self-locking safety, wherein a rotating rod is arranged at the upper part of a worm wheel shaft and is used for rotatably disassembling a tyre and a steel ring, and a pushing-down rod at the middle part of the worm wheel shaft is used for removing residual air pressure in the tyre and provides convenience for the rotating rod at the upper part to go deep into an internal opening of the tyre to realize rotary disassembly. A support hook on a rectangular threaded mainshaft jacks a vehicle up when the worm wheel rotates clockwise and puts the vehicle down when the worn wheel rotates anticlockwise; and the on-vehicle jack is suitable for modern fast-paced requirements.
Description
Technical field
The present invention relates to instrument of vehicle maintenance and repair, general tool high-mobility, multipurpose, wheeled vehicle comprehensive development and utilization belongs to the vehicle maintenance and repair engineering.
Background technology
Existing automobile basic hand tool jack, great majority are hydraulic jacks, the STRTHD mechanical jack, vehicle runs into tire and does not have air pressure in the way of travelling, can not travel, very inconvenient when changing tire, the rising balanced structure does not meet modern fast pace requirement, wastes time and energy, concerning chaufeur, buy that new car configures like this also without way.Even to market, buy, also all be outmoded, everybody wants to reduce unnecessary loss and waste of time.
Summary of the invention
Purpose of the present invention is to reduce unnecessary loss, from economical and practical durable purpose, according to the particular case of automobile chassis structures principle, designs a kind of multi-functional jack, not only can raise, can also the dismounting retread a tyre.Can dismounting roadlice vacuum tyre, again can dismounting truck conventional tyre, the expert can also self repairing tyre, and is convenient and practical, reaches driving safety, economic effect.
In order to address the above problem, technical scheme of the present invention is: according to worm drive, transmitting ratio is large, equivalent friction angle, the groundwork of self locking safety, transmit motion and the power of alternating axis, worm screw is driving link, and turbine is driven member, and worm-wheel shaft top revolving bar rotates to the power dismounting, left side, middle part down-pressed pole is removed residual air pressure in the tire, is convenient to revolving bar and gos deep into tire internal orifice rotation dismounting.The positive hour hands rotation of worm gear, the square thread hook of middle and lower part holds up vehicle one side height, is convenient to changing of tire, inhour rotation can be put down the height of picking-up, no matter is to raise or put down, add great power at worm gear, all can not make worm drive, reached the self locking safety effect.
The present invention compares with other hydraulic jack, screw thread mechanical jack, have the physics of meeting, mechanical engineering, mechanics, worm drive groundwork, vacuum tyre according to roadlice, truck, the specific requirement of common tire, can rise, again can the dismounting retread a tyre, performance is with the effect of car multi-functional jack, adapt to modern society's fast pace requirement, be users' service.
Description of drawings
Below in conjunction with accompanying drawing, the invention will be further described.
Fig. 1 is that the present invention is a kind of with the car multi-functional jack, the block diagram schematic diagram.
Fig. 2 is that the present invention is a kind of with the car multi-functional jack, front view basic comprising schematic diagram.
Wherein among Fig. 2,1 is the supporting ﹠ stablizing bar, and 2 is movable down-pressed pole, and 3 is revolving bar, and 4 is worm and gear, and 5 is worm and gear support disk seat, and 6 is hook, and 7 is the square thread main shaft, and 8 is jack base.
The specific embodiment
When practical set was used, square thread main shaft and worm and gear support disk seat, jack base were to be flexibly connected into integral body, supporting ﹠ stablizing bar captive joint, and worm and gear support disk seat, with jack base, steady transmission when jack is born a heavy burden.Worm and gear and square thread spindle mounted are integral, and the hook by on the worm and gear rotation square thread just moves up and down, and hand of rotation is different, play rising or put down height of car also different.The revolving bar on square thread main shaft top, running-fit is fixed on the axle, is convenient to dismounting and uses and carry.
When the chaufeur changing of tire, as long as rotary worm drives worm-wheel shaft, hook just can very fast jack-up vehicle, complete opposite spin in man-hour worm screw, just can put down vehicle, left side movable down-pressed pole and top revolving bar, according to demand press go the residual air pressure after, make tire under the turning effort of revolving bar, tire and steel ring are decomposed out very soon, reach the purpose of changing and repairing, can both operate whenever and wherever possible, convenient and swift.
Claims (3)
1. one kind with the car multi-functional jack, it is characterized in that: it comprises that supporting ﹠ stablizing bar 1 and square thread main shaft 7, worm and gear support disk seat 5, jack base 8 are assembled into integral body, and worm and gear 4 is assembled into an axle form with square thread main shaft 7.
2. according to claim 1 a kind of with the car multi-functional jack, it is characterized in that: revolving bar is with the rotation of square thread main shaft, and dismounting vacuum tyre or common tire, movable down-pressed pole are removed residual air pressure in the tire, are convenient to revolving bar and decompose tire and steel ring.
3. according to claim 1 a kind of with the car multi-functional jack, it is characterized in that: square thread main shaft and worm and gear support disk seat, jack base all are the running-fit assemblings, and combination is easy to carry.
