Abstract
The invention discloses a shear type jack and belongs to the field of automobile equipment. The shear type jack comprises a supporting seat, a base, a pair of upper arms and a pair of lower arms, wherein one end of each upper arm is mounted on the supporting seat and the other end of each upper arm and one end of each lower arm are connected by two hinging shafts; the other end of each lower arm is mounted on the base; a screw rod is arranged between the two hinging shafts in a penetrating manner; a foldable reinforcing plate is fixedly mounted at the bottom of the base; the foldable reinforcing plate comprises two steel plates; the two steel plates are hinged with the base respectively, and can be expanded towards the two opposite sides of the base. The foldable reinforcing plate is arranged at the bottom of the base so that the contact area between the whole jack and the ground is enlarged while the normal structure is guaranteed, and furthermore, the jack can be applicable to various overweight environments and the damages to the road surface are avoided.
Description
Technical field
The present invention relates to a kind of jack, be specifically a kind of scissor-like jack, belong to field of vehicle equipment.
Background technology
Scissor-like jack is a kind of common weight-lifting equipment, is mainly used in the jack-up of the automobile of little tonnage.Existing scissor-like jack considers compact conformation and portability, and its base bearing surface is usually little, the ground that the soil is porous uses and needs could use by other upholder, make troubles to interim urgent need; Meanwhile, because bearing surface is little, also easy in overweight process damage is caused to normal road surface.
Summary of the invention
Technical matters to be solved by this invention is to overcome prior art defect, provides a kind of area of thrust surface large and the scissor-like jack of compact conformation.
In order to solve the problems of the technologies described above, scissor-like jack provided by the invention, comprise supporting seat, base, a pair upper arm and a pair underarm, one end of described upper arm is arranged on supporting seat, the other end of upper arm is connected by two jointed shafts with one end of underarm, the other end of underarm is arranged on base, leading screw is installed between two jointed shafts, the fixed installation of described base bottom can folding brace panel, two block plates can be comprised by folding brace panel, two block plates are hinged with base respectively, can launch both sides in opposite directions to base.
In the present invention, describedly the lower surface of folding brace panel can be provided with skid resistant course.
In the present invention, described skid resistant course is pvc rubber cushion.
In the present invention, the top of described supporting seat is provided with rubber antiskid layer, and described rubber antiskid layer upper surface is broached-tooth design.
Beneficial effect of the present invention is: (1), folding brace panel by base bottom, while guarantee normal configuration, add the area of contact on whole jack and ground, make jack be applicable to various genvironments, and avoid road pavement to cause damage; (2), can the lower surface of folding brace panel to set up defences slip layer, the stability in the super lifting process of scissor-like jack can be improved, avoid sliding, cause accident; (3), the top of supporting seat establishes rubber antiskid layer, can reduce the damage to vehicle, improve the stability of lifting.
Accompanying drawing explanation
Fig. 1 is scissor-like jack schematic diagram of the present invention;
Fig. 2 is that the present invention can folding brace panel structural representation.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail.
As illustrated in fig. 1 and 2, scissor-like jack of the present invention, comprises supporting seat 4, base 1, a pair upper arm 3 and a pair underarm 2.One end of upper arm 3 is arranged on supporting seat 4, and the top of supporting seat 4 is provided with rubber antiskid layer 7, and rubber antiskid layer 7 upper surface is broached-tooth design.The other end of upper arm 3 is connected by two jointed shafts 9 with one end of underarm 2, and the other end of underarm 3 is installed on the base 3, installs leading screw 5 between two jointed shafts 9.
Bottom base 1, fixed installation can folding brace panel, can folding brace panel to comprise two block plate 6, two block plates 6 hinged with base 1 respectively, can launch to base 1 left and right sides, also can pack up in the inner chamber be folded to bottom base 1 in opposite directions.Be provided with pvc rubber cushion at the lower surface of every block plate 6, to strengthen the contact friction with ground in lifting process, prevent to slide.
During use, by can launch to both sides by folding brace panel bottom base 1, form plane, support on the ground, increase the area of thrust surface on base 1 and ground, thus use scissor-like jack more stable; Under scissor-like jack being supported on the required automobile position supported, penetrate in the hole of bar head of screw mandrel 5 with boosting-rod, rotary screw rod 5 lifts or puts down scissor-like jack; After lifting terminates, two block plate 6 doublings are fitted in closing at bottom base 1 inner chamber.
The above is only the preferred embodiment of the present invention, it should be pointed out that for those skilled in the art, can also make some improvement under the premise without departing from the principles of the invention, and these improvement also should be considered as protection scope of the present invention.
