Abstract

The utility model relates to a foldable operating handle for a scissor jack, which belongs to the lifting operating component of the jack. The utility model comprises an engagement seat 11 whose wall body is symmetrically folded into a concave part 15, a connecting rod 1 connected with one end of the concave part 15 of the engagement seat and a rocking arm 4 connected with the other end of the concave part 15 of the engagement seat 11. The utility model has the advantages that the occupying storage space can be reduced, the entire volume of the factory package of a factory can be reduced, etc.

Description

The collapsible operating handle of scissors-type jack

The utility model relates to the collapsible operating handle of a kind of scissors-type jack, belongs to jack lifting control member.

The operating handle of existing scissors-type jack, it is that pitman and rocking arm one are constituted the rocking handle that likeness in form is started walker tractor, though the operating handle of this structure can play the scissors-type jack lifting/lowering effect freely that makes, but because operating handle can not fold, thereby when the time with complete collection, tend to take bigger collection space, and the packing of dispatching from the factory of factory is also brought the problem that is difficult to littleization packaging volume.

Task of the present utility model is to provide a kind of can dwindling to take collection space, dissolve the collapsible operating handle of scissors-type jack of factory's packaging volume for a short time.

Task of the present utility model is finished like this, and the collapsible operating handle of a kind of scissors-type jack comprises a connecting base 11, and its wall body symmetry is amounted to into tool one recess 15; One pitman 1 is connected an end of the recess 15 of connecting base 11; One Rocker arm 4 is connected the other end of the recess 15 of connecting base 11.

The utility model has been owing to adopted said structure, can be as required and with pitman 1 pull to and by to Rocker arm 4, thereby can dwindle its collection space that takies and the overall volume of the packing of can little chemical plant dispatching from the factory.

Below in conjunction with accompanying drawing the utility model is further described below.

Fig. 1 is the utility model constructional drawing.

Fig. 2 is the utility model folded state diagram.

Be respectively equipped with inner convex platform 12,8 on the connecting base 11 of the present utility model, pitman 1 and Rocker arm 4 base portion are respectively equipped with pit 2, through hole 6, and inner convex platform 12,8 protrudes into pit 2 and through hole 6 respectively.When the utility model entered running condition, the curling position with pitman 1 during by previous adjacent Rocker arm 4 became and the perpendicular position of Rocker arm 4, and makes inner convex platform 12 protrude into pit 2.Because of inner convex platform 12 protrudes into pit 2, thereby can guarantee further that pitman 1 is when running condition and the accurate location of connecting base 11.In addition because inner convex platform 8 protrudes into through hole 6, thereby can make Rocker arm 4 and connecting base 11 fully fixing.

Be shaped on rivet hole 10 and through hole 13 on connecting base 11 of the present utility model and the pitman 1 respectively in advance, with rivet 9 riveting successively go into rivet hole 10 and through hole 13 make can realize the wall body of pitman 1 base portion and connecting base 11 is hinged and be positioned at recess 15; On connecting base 11 and Rocker arm 4, be shaped on

rivet hole

14,5 respectively, rivet 7 riveting successively gone into

rivet hole

14,5 just can realize hanging down the wall body of Rocker arm 4 base portion and connecting base 11 solid and being positioned at recess 15.

At ordinary times, when the utility model is in stand-by state, need only pitman 1 switching to folded state shown in Figure 2.And in the time will using, then pitman 1 is pulled to shown in Figure 1 and the perpendicular position of Rocker arm 4, and the end that makes pitman 1 hooks the screw rod delthyrium on the scissors-type jack, as long as holding the handle 3 of Rocker arm 4 end this moment shakes to clockwise direction, pitman 1 also rotates with clockwise direction, thereby drive the screw rod rotation of scissors-type jack, by the rotation of screw rod a pair of supporting arm that is spirally connected with it is inwardly drawn in gradually, the saddle that places on the supporting arm is risen gradually, will be held up gradually by the object of lifting.With finishing, just shake Rocker arm 4 to anticlockwise direction, after the supporting arm of scissors-type jack resets to initial condition, take off pitman 1, and with its switching to folded state shown in Figure 2, standby to collect.
