Abstract
The invention discloses a jack, and relates to the technical field of production of vehicle fittings. The jack comprises two upper arms hinged to an upper support base through upper hinge shafts, and two lower arms hinged to a lower support base through lower hinge shafts, wherein the upper arms and the lower arms are hinged by middle hinge shafts; and hinge holes are formed in the hinged ends of the lower arms and the upper arms, and are through holes with closed top hole walls. Compared with the prior art, the jack generates no phenomenon of drop of the middle hinge shafts from the hinged ends due to the deformation of the hinge holes in the use process, so that the safety and the stability are improved.
Description
Technical field
The present invention relates to vehicular spare parts manufacturing technology field, especially a kind of for being provided in servicing a car on automobile time jack that body part is lifted.
Background technology
Jack be vehicle maintenance and repair or change tire time one of essential instrument, have a kind of technical scheme of jack of mini van to be: this jack includes and is hinged on a pair upper arm between upper support seat and lower support seat and a pair underarm, described upper arm and described underarm hinged respectively by two middle hinge shaft; In being provided with hinge hole with described upper arm pin jointed end, be provided with opening at the hole wall top of described hinge hole upper end.In use there is following deficiency in the technical scheme of this jack: 1, because the hinge hole of underarm one end is provided with opening, when the load of jack is excessive, hinge hole opening part easily splits and underarm is come off from jointed shaft, damages the stability of jack use safety; 2, because upper arm and underarm are welded by tooth plate and armed lever to form, easily because welding residual stress causes tooth plate to rupture from commissure in use procedure, the stability of jack use safety is damaged.
Summary of the invention
The technical problem to be solved in the present invention is to provide the good jack of a kind of safety performance.
The technical scheme that technical solution problem of the present invention adopts is: this jack comprises two underarms being hinged on two upper arm on upper support seat respectively by upper hinge and being hinged on by down hinge on lower support seat, middle hinge shaft is hinged respectively for described upper arm and described underarm, described underarm is in being provided with hinge hole with described upper arm pin jointed end, and described hinge hole is the through hole that top hole wall is closed.
In above-mentioned jack technical scheme, technical scheme can also be more specifically: it is the end plate being provided with tooth that described upper arm is positioned at upper support seat one end, and two described upper arm are connected with a joggle by the tooth on its end plate; It is the tailgate portion being provided with tooth that described underarm is positioned at lower support seat one end, and two described underarms are connected with a joggle by the tooth on its tailgate.
Owing to have employed technique scheme, the present invention compared with prior art, the beneficial effect had is: 1, underarm does not establish opening in the hinge hole with upper arm pin jointed end, jack in use can not from producing because hinge hole be out of shape the phenomenon that middle hinge shaft comes off from pin jointed end, and security and stability improves; 2, upper arm and underarm are connected with a joggle by tooth all adopting with the pin jointed end of upper support seat and lower support seat respectively, and self-locking property is good, and safety improves.
Accompanying drawing explanation
Fig. 1 is the structural representation of the jack underarm of prior art.
Fig. 2 is the structural representation of the embodiment of the present invention.
Fig. 3 is the connection diagram of embodiment of the present invention upper arm and underarm.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described:
Jack as shown in Figure 2 and Figure 3 comprises two underarms 2 being hinged on two upper arm 5 on upper support seat 6 respectively by two upper hinge 6-1 and being hinged on by down hinge 1-1 on lower support seat 1, two middle hinge shaft 4 are hinged respectively for two upper arm 5 and two underarms 2, underarm 2 is in being provided with hinge hole with upper arm 5 pin jointed end, hinge hole is the through hole that top hole wall is closed, can not from producing because hinge hole be out of shape the phenomenon that middle hinge shaft comes off from pin jointed end, security and stability improves.It is the end plate being provided with tooth that upper arm 5 is positioned at upper support seat 6 one end, and two upper arm 5 are connected with a joggle by the tooth on its end plate; It is the tailgate portion being provided with tooth that underarm 2 is positioned at lower support seat 1 one end, and two underarms 2 are connected with a joggle by the tooth on its tailgate.Between two middle joint spindle 4, be coated with leading screw 3, the middle part of jointed shaft 4 is provided with screw thread.
During work, under jack being supported on the required automobile position supported, penetrate in the hole of bar head of screw mandrel 3 with boosting-rod, rotary screw rod 3 lifts or puts down jack.
