Main purpose of the present utility model is, a kind of scissors-type jack is provided, it is to be provided with one can supply the fixing permanent seat of push rod on the locating piece on jack top, the length of this push rod can be changed it according to the height of chassis, also push rod can be taken off to be applicable to the chassis of general minibus, make things convenient for the user be used in different chassis heights vehicle rise operation.
Scissors-type jack provided by the utility model, it is provided with driving device and several lower links is set on base plate on the body base plate, lower link articulates with boxed rod respectively, each boxed rod one end is connected with positioning seat respectively, the positioning seat top is provided with locating piece, between several lower links, oil hydraulic cylinder is set in addition, the oil hydraulic cylinder top is provided with the plane, this plane pivot joint is several can be by the drive link of oil hydraulic cylinder drive, drive link end in addition is fixed on the lower link, make drive link drive lower link and boxed rod, and then the positioning seat fixed of drive and boxed rod and locating piece be to top offset, Qi Tete is:
On positioning seat, locating piece, form straight hole, circular hole respectively, and the set collar with through hole is set in locating piece top, permanent seat is arranged in through hole, straight hole and the circular hole, and permanent seat welds with set collar and positioning seat respectively, permanent seat is provided with screw, and screw can be solid for being provided with externally threaded push rod spiral shell.
In above-mentioned scissors-type jack, the top of this push rod can be formed with the lines that increases friction force; Positioning seat can design straight hole, and push rod then can be designed to straight-bar and cooperation is provided with block, locatees for being set in the straight hole.
Effect of the present utility model is the chassis that is easy to use in differing heights, the utility model is provided with a positioning block in the positioning seat top of body top, one set collar is set on the locating piece, permanent seat welds with set collar and positioning seat respectively, and the formation of permanent seat central authorities can be for the fixing screw of push rod, the length of this push rod can change it according to the height of chassis, select for use with the handled easily person differing heights chassis vehicle rise operation.
Structure of the present utility model simplifies, simple to operate, the person of being convenient to operation uses, particularly applicable to various vehicles with different chassis heights, one-object-many-purposes, natural effect multiplication.
Further specify specific structural features of the present utility model and purpose below in conjunction with accompanying drawing.
Brief Description Of Drawings:
Fig. 1 is a schematic appearance of the present utility model.
Fig. 2 is a front-view schematic diagram of the present utility model.
Fig. 3 is an embodiment scheme drawing of the present utility model.
Fig. 4 is the embodiment scheme drawing of existing jack.
Please referring to Fig. 1, shown in 2, this is a scheme drawing of the present utility model, it is that a body 10 is set, body 10 has a base plate 14, four lower links 11 are set in the appropriate location on the base plate 14, lower link 11 articulates with boxed rod 111 respectively, boxed rod 111 1 ends and positioning seat 17 articulate, and a positioning block 171 is set in positioning seat 17 tops, the external diameter of the central corresponding permanent seat 18 of positioning seat 17 and locating piece 171 forms straight hole 173 and circular hole 172, circular hole 172 tops are provided with the set collar 30 of an external diameter greater than circular hole 172 diameters, set collar 30 central corresponding circular holes 172 form a through hole 31, permanent seat 18 is arranged in straight hole 173, in circular hole 172 and the through hole 31, and the outside of permanent seat 30 is welded in set collar 30 and positioning seat 17 respectively, making permanent seat 18 tops is low than the top of locating piece 171, permanent seat 18 central authorities one have the screw 181 of negative thread, but these screw 181 sacrificial vessels have the push rod 20 of outside thread 22 to screw togather, and push rod 20 tops have lines 21, being positioned at four lower link 11 inboards on base plate 14 is provided with an oil hydraulic cylinder 12 in addition, oil hydraulic cylinder 12 tops are provided with a plane 122, plane 122 2 sides are provided with four drive links 121, and each drive link 121 1 end is individually fixed in the appropriate location of lower link 11.
