Problems solved by technology

However, the frequency of use of household jacks is relatively low, and it is generally idle for a long time, which easily leads to rust on the screw and hinged shaft, making it difficult to rotate the screw, which affects the use
In addition, due to the lack of effective lubrication, the wear between the screw and the hinge shaft is relatively large during long-term use, which affects the lifting stability of the jack

Embodiment Construction

[0012] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0013] Such as figure 1 and 2 As shown, the jack for a small car of the present invention includes a support base 4, a base 1, a pair of upper arms 3 and a pair of lower arms 2. One end of the upper arm 3 is installed on the support base 4, and the top of the support base 4 is provided with a rubber anti-skid layer 7, and the upper surface of the rubber anti-skid layer 7 has a sawtooth structure, which can increase the contact friction with the car body and improve the stability of the super-slip. Avoid damaging the vehicle body. The other end of the upper arm 3 is connected to one end of the lower arm 2 through two hinge shafts 6 respectively, and the other end of the lower arm 2 is installed on the base 1 .

[0014] The inner sides of the two hinged shafts 6 are connected with a lubricating oil sleeve 8, and the inner wall of the lubricating oil sleeve ...

Abstract

The invention discloses a jack for a small automobile and belongs to the field of automobile auxiliary equipment. The jack comprises a supporting seat, a base, a pair of upper arms and a pair of lower arms. One end of each upper arm is installed on the supporting seat, the other end of each upper arm is connected with one end of each lower arm through two hinged shafts, the other end of each lower arm is installed on the base, and a screw rod penetrates between the two hinged shafts. The inner side of at least one hinged shaft is connected with a lubricating oil sleeve, an annular oil storage ring adheres to an inner side wall of the lubricating oil sleeve, and the screw rod penetrates the oil storage ring and the lubricating oil sleeve. Through the matching of the oil storage ring and the lubricating oil sleeve, the screw rod and the hinged shafts can be continuously lubricated, the abrasion between the screw rod and the hinged shafts is reduced, the lifting stability is improved; meanwhile, the rusting caused by no use for a long time is avoided; the oil storage ring can lock lubricating oil while providing lubricating oil and can supply the lubricating oil for a long time; and the lubricating oil sleeve can reduce the volatilization of the lubricating oil.

Description

technical field [0001] The invention relates to a jack, in particular to a jack for a small car, which belongs to the field of car auxiliary equipment. Background technique [0002] The jack is one of the essential tools for car maintenance or tire replacement. The common jack for small cars is a diamond-shaped hand-cranked jack, which can be raised and lowered by the rotation of the screw. Small space, favored by the majority of car owners. However, the frequency of use of the household jack is relatively low, and it is generally idle for a long time, which easily causes the lead screw and hinged shaft to rust, and the lead screw is difficult to rotate, which affects the use. In addition, due to the lack of effective lubrication, the wear between the screw and the hinge shaft is relatively large during long-term use, which affects the lifting stability of the jack. Contents of the invention [0003] The technical problem solved by the invention is to overcome the de...
