Sinking-preventive and antiskid combined scissor jack for wheels

Abstract

The invention discloses a sinking-preventive and antiskid combined scissor jack for wheels. The sinking-preventive and antiskid combined scissor jack comprises a jack body. The jack body is provided with an upper hinge seat and a lower hinge seat, left hinge arms and right hinge arms are arranged between the upper hinge seat and the lower hinge seat of the jack body, threaded holes are formed in hinge pins arranged in the middles of the left hinge arms and the right hinge arms, threaded sleeves are arranged on the hinge pins, rotary lead screws are arranged between the hinge pins of the left hinge arms and the right hinge arms, each of the left hinge arms and the right hinge arms is divided into a free arm and a rotary arm, the free arms are hinged onto the hinge pins, the rotary arms arehinged onto the hinge seats, detachable connection structures are arranged between the free arms and the rotary arms, and extension ends which spread towards the outer sides of the hinge pins along the free arms are arranged on the free arms. The sinking-preventive and antiskid combined scissor jack has the advantages that the sinking-preventive and antiskid combined scissor jack is simple in structure, small in occupied space, convenient to disassemble and carry, free of damage on vehicles and good in universality, can be used as a jack after components of the sinking-preventive and antiskidcombined scissor jack are combined with one another, can assist in realizing sinking-preventive and antiskid effects for the wheels after the components are split and mounted, and has four practical functions, and the sinking-preventive and antiskid effects can be simultaneously realized by the sinking-preventive and antiskid combined scissor jack.

Description

technical field [0001] The invention relates to a combined scissor jack used for anti-sinking and anti-slipping of wheels. Background technique [0002] Most of the common wheel anti-slip devices and wheel anti-sinking devices are similar to filling additions between the wheel and the ground to support and increase friction. Most of these devices have complex structures, which are troublesome to install and disassemble. Inconvenience, low reliability, single function, poor versatility, and high manufacturing costs; and existing vehicle jacks often have and only have one function, which is used as a temporary support during vehicle maintenance. Contents of the invention [0003] The object of the present invention is to provide a combination scissor jack for anti-slip and anti-slip of wheels, which not only has the basic function of a jack, but also can play the role of anti-slip and anti-slip of wheels, and has multiple functions. [0004] The object of the present invent...
