Abstract

The utility model relates to a scissor jack head, which is the improvement of the prior jack head. The utility model is particularly suitable for the buggy, the minibus and the car lighter than 2 tons. The utility model comprises a saddle 1 and a support base 8. The saddle 1 is provided with a slot 2. The support base 8 is fixed in the slot 2. The utility model has the advantages of reasonable structure, high anti-compression strength, good stability, etc. The utility model can be simultaneously and universally used on the car, the buggy and the minibus.

Description

The scissors-type jack top

The utility model relates to a kind of scissors-type jack top, is the improvement to existing jacking header, is specially adapted to use on the pony truck, utility van, car below 2 tons.

At present, employed jack on domestic baby truck, utility van, the car, the form of its top mainly contains two classes, and a class is a planar shaped, be the plane by the contact surface between jack-up thing and the jacking header promptly, this class jack is mainly used in pony truck or the utility van that the housing junction does not have convex tendon; And another kind of be flute profile, promptly on the top of jack, offer groove, this class jack mainly is applicable to car, because a convex tendon is arranged at the shell of car and the junction of drain pan,, when remove a tyre, the convex tendon position should be positioned in the groove of top by the job requirement car, in order to avoid the damage housing.Above-mentioned two class jacks, because the jack of flute profile top exists defectives such as compressive strength is lower, poor stability, so the two can not exchange, commonality is poor.

The purpose of this utility model be to provide a kind of rational in infrastructure, can be simultaneously general on car, pony truck, utility van, compressive strength is high, the scissors-type jack of good stability top.

The purpose of this utility model is achieved like this, a kind of scissors-type jack top, and it includes saddle 1, supporting base 8, offers groove 2 on saddle 1, and supporting base 8 is fixed in the groove 2.

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

Fig. 1 is a three-dimensional structure diagram of the present utility model.

Fig. 2 is installed on structure diagram on the scissors-type jack for the utility model.

Supporting base 8 of the present utility model is to be made of groove body 14, bottom land 13, two side-struts 9 "

" shape.The supporting base 8 that is made of groove body 14, bottom land 13, two side-struts 9 can adopt the metallic material integrated punching to form, and is equipped with a flange 10 at the midway location place of each side-strut 9, flange 10 with can coincide after the recessed edge 3 of groove 2 cooperates.On bottom land 13, be provided with boss 11, on the both sides of boss 11, bottom land 13, respectively have a location cylindrical void 12, behind the positioning strip 5 on cylindrical void 12 insertion grooves 2 of location, positioning strip 5 inwardly or is outwards turned over, can be on groove 2 with supporting base 8 rivet clasps.

Groove 2 of the present utility model be shaped as stepped appearance, be opened on the saddle 1.Saddle 1 can adopt metallic material to be made, and offers pin shaft hole 7 on saddle 1, pin shaft hole 7 by bearing pin with the top ends of saddle 1 rivet clasp at two upper support arms of scissors-type jack.Left and right recessed edge 3, supporting station 4, positioning strip 5, the bottom land saddle 6 offered symmetrically on groove 2.The utility model is when being installed on supporting base 8 on the saddle 1, at first with the positioning strip 5 on location cylindrical void 12 alignment slots 2 of supporting base 8, insert downwards then, bottom land 13 until supporting base 8 contacts with bottom land saddle 6, the side-strut 9 of supporting base 8 is with till supporting station 4 contacts, at this moment the flange 10 on the side-strut 9 just is embedded in the recessed edge 3 of groove 2 mutually, and the last plane of the last plane of the supporting base 8 after guaranteeing to install and saddle 1 is in the same plane.Like this, when coming directly towards at top pony truck or utility van, because of the last plane of the last plane of supporting base 8 and saddle 1 in the same plane, so increased the area of contact of top and jacked object spare, compare with the ordinary jack top, improve compressive strength, increased the stability of jack, safer when jack is used.

The length of supporting base 8 of the present utility model is greater than the width of saddle 1.Like this, when top during at the top car, as long as with the shell 15 of car with in the convex tendon of drain pan junction is aimed at the groove of supporting base 8.Because the length of supporting base 8 is bigger than the width of saddle 1, therefore increased the area of contact of top and car shell relatively, reduced pressure, more can protect the shell of car, make it injury-free; Relative stability when simultaneously also having increased top lifting has improved the safety performance of jack.

The utility model is because after adopting above-mentioned top structure, as long as in the lifting scope of scissors-type jack, both applicablely uses on pony truck, utility van, applicablely again uses on car, and commonality is extremely strong; Secondly, owing to increased the area of contact that comes directly towards and lifted between the object, therefore improved the stability of jack relatively; Simultaneously, can effectively alleviate damage to automobile case.
