Description

Garage jack

The utility model relates to a kind of garage jack, but it is a kind of taking over a business seat, the wheel that strengthens and taking over a business the garage jack that the angle tooth that installs additional in the seat is increased the upholder lift height of lengthening that utilize.

In the environment of our life, it is to surpass people can bear a heavy burden that many article are arranged, therefore the clever mankind have just invented the free-hand instrument of moving of many replacements, as hand barrow, raise machine, transport trolley, jack etc., wherein be commonly the general common people or family is used with jack, the personage that car stratum is particularly arranged, one of salvage tool of statutory regulations indispensability when jack has been road travel; Therefore,,, also can't effectively wheel be risen even just simply change tire work if do not have a tool practicality, convenience, can solve the jack of any ground condition problem, below the spy with employed jack in the past and the jack after improveing do a detailed description.

See also shown in Figure 1ly, existing garage jack mainly comprises body 6, take over a business seat 7 and take over a business 8, wherein:

The mechanism and the subsidiary of pulling control jack liftings such as gold, oil hydraulic system, rocking bar, rocking arm, wheel that comprise jack in this body 6.

This is taken over a business seat 7 and is the Pie shape, and below two circular holes are provided with anchor shaft can articulate rocking arm and rocking bar, and the top is then accepted this and taken over a business 8.

This takes over a business 8 is a discoid body, and the dish edge is " imperial crown " shape, is riveted on the seat 7 with anchor shaft, makes 8 freely rotatable.

Can form the jack that is used for dilly by above-mentioned member, garage jack be placed want elevate a turnable ladder vehicle or underbelly, sheet metal 61 fluctuates, make oil hydraulic system produce pressure, slowly rocking bar 63, rocking arm 64 are lifted, utilize again and rotatablely take over a business 8, gradually upholder is lifted high.

Yet when this kind jack was used in full size vehicle, the chassis of therefore planting vehicle was too high, can't effectively promote height of car, unless use more large-scale but not portative jack, however the jack that generally is equipped with in car all belongs to convenience type.

The purpose of this utility model is to provide a kind of garage jack, and it can improve the lift height of jack, and can stablize, support safely the object of institute's elevate a turnable ladder.

The purpose of this utility model is to realize like this, a kind of garage jack promptly is provided, it comprises body, angle tooth, takes over a business and take over a business seat, described angle tooth is a screw shaped cylinder, the bar head is provided with several anti-skidding projections, shaft is provided with around the screw thread that circles round, and the bar tail has the riveting of avoiding the angle tooth excessively to screw out and spends outer design of opening; Describedly take over a business seat and be Pie shape extended type, below two circular holes articulate rocking arm and rocking bar with anchor shaft, and the top accepts describedly to take over a business, inboard then be provided with the internal screw thread sleeve of angle tooth and auxiliary its lifting and the fixing set collar of internal screw thread sleeve, it is described that to take over a business be a discoid body, periphery is lower recess on the U type, and the centre is provided with the hole that screws in for described angle tooth.

The advantage of the utility model device is, by the back-out of angle tooth and the angle tooth is hidden and lift adjustment and extend take over a business seat can make the lift height of jack improve, and by the anti-skidding projection of angle tooth supporting object more safely and steadly.

Below in conjunction with accompanying drawing, embodiment of the present utility model is described, wherein:

Fig. 1 is the planar view of existing garage jack;

Fig. 2 is a schematic perspective view of the present utility model;

Fig. 3 is a planar view of the present utility model;

Fig. 4 is a part action scheme drawing of the present utility model;

Fig. 5,5A, 5B are existing thousand tops and action comparison diagram of the present utility model.

See also shown in Fig. 2 to 4, the utility model garage jack comprises body 1, angle tooth 2, takes over a business seat 3, takes over a business 4, wherein:

This body 1 is the part of control jack lifting, and it mainly comprises pulls gold 11, oil hydraulic system 12, rocking bar 13, rocking arm 14, wheel 15, is made of the keystone configuration of jack above-mentioned member.

This angle tooth 2 is a screw shaped cylinder, and the bar head is provided with several anti-skidding projections 21, and shaft is provided with around the screw thread that circles round, and the bar tail has riveting to spend the outer design of opening, and avoids angle tooth 2 excessively to screw out.

This is taken over a business seat 3 and is the Pie shape, and below two circular holes are articulated in rocking arm 14, rocking bar 13 with anchor shaft, and the top accepts 4, and the inboard then is welded with set collar 31, internal screw thread sleeve 32 and angle tooth 2.

This takes over a business 4 is a discoid body, and periphery is lower recess on the U type, and the centre has hole to screw in for angle tooth 2, but angle tooth 2 and to take over a business 4 be not to closely combine turns so take over a business still.

Can form a garage jack by above-mentioned member, its enforcement is as follows:

Earlier angle tooth 2 is slowly screwed out to the appropriate location by taking over a business 4 central authorities, again jack is placed the object below of wanting lifting, at this moment, with stone or sleeper that wheel 15 is fixing, fluctuate and pull gold 11, make oil hydraulic system 12 produce the oil pressure thrusts rocking arm 14, rocking bar 13 are slowly risen, by the height of angle tooth 2 and take over a business the lengthening height of seat 3, it is high to make the aspect ratio of object lifting have jack now.

In addition, the valve in the oil hydraulic system 12 can be discharged by the master cock on the rotating body 1 100, make the push rod back pressure, at this moment, the rocking bar 13, the rocking arm 14 that are articulated in oil hydraulic system 12 just slowly descend, and jack is returned back to original position; If upholder is not high, angle tooth 2 can revolve and be put in extreme lower position (as shown in phantom in Figure 4), only substitutes support to take over a business 4; The anti-skidding projection 21 of angle tooth 2 upper ends can prevent the displacement of vehicle, upholder, slide, and the riveting of its bar tail is spent and opened design and more can avoid angle tooth 2 excessively to screw out and drop, lose outward.

Via the foregoing description, and consult shown in Figure 5ly, the utility model is compared with existing apparatus has following characteristics:

The first, wheel diameter of the present utility model strengthens, and lifts the height except that improving, and more can increase the stability of jack, shown in Fig. 5 B.

The second, the utility model is for making the angle tooth can lift adjustment, the spy will take over a business seat more existing add much longer, but increased the height of jack lifting itself virtually also, shown in Fig. 5 A.

Three, angle of the present utility model tooth runs through to take over a business and is articulated in the seat, replaces in the existing structure in a fixed manner, and the effect of fixedly taking over a business is not only arranged, and more can bring into play the benefit that it increases, and is to have many-sided usefulness.

Four, angle of the present utility model crest portion is provided with anti-skidding projection, can prevent slip, the displacement of vehicle and object, and safety, firm effect are arranged.
