Abstract

The utility model discloses a jack support, and the volume of the utility model is greatly reduced when the jack support is folded. A supporting frame is composed of two supporting plates, and both sides of the supporting plate are bended to side wing plates. The upper end of the side wing plate is hinged with an extending plate downwards bended form a platform, and the lower part of the side wing plate is mutually hinged with a leaning and combining plate by a shelving plate. The center of the platform is welded with a locating sleeve, a post rod is inserted into the locating sleeve, and radial through holes are arranged on the locating sleeve. The post rod is provided with a plurality of radial through holes, the supporting frame is connected with a pin used for locking the post rod by a chain, and the upper part of the post rod is provided with a radial screw hole used for matching with a screw rod. The jack support can lift heavy articles to be lifted by matching with jacks, and is suitable for lifting different heights; the utility model has the advantages of convenient operation, and small volume in a folded state.

Description

Jack stand

The utility model relates to bracing frame, particularly is matched with the upper frame that jack uses.

Oil jack is widely used in numerous occasions that need the top to lift heavy thing, is commonly used especially in automotive servicing.Oil jack is easy to use, laborsaving, and top lifting force amount is big.But, this jack also has its defective, and Here it is, and there is the possibility of liquid oil leakage in high-voltage oil cylinder.When jack was praised weight, in case oil cylinder liquid oil leakage, the weight of not only can not jerking also may cause contingency, because by the landing suddenly unexpectedly of the weight of lifting, its consequence is hardly imaginable.Behind jack clean and jerk weight, be used a kind of jack stand, support places the bottom of the weight of jerking, and can avoid jack to meet accident because of the long-time leakage of oil of bearing a heavy burden, and removable jack is used to do him.Existing jack stand also claims the A cabinet frame, and its defective is to take up space greatly.This not only becomes problem at car repair shop, uses on vehicle, being equipped with band, and trouble more then, to put this upper frame be a kind of not thing easily really because will tidy up in limited space.

It is convenient to put when the purpose of this utility model is to provide a kind of non-working condition, the little jack stand that takes up space, and this jack stand can fold storing.

The technical solution of the jack stand of the utility model is to be provided with support, the support upper end is provided with platform, wear in the platform and be fixed with locating bush, be plugged with push rod in the locating bush, its special character is, support is made up of two support bodies corresponding to the symmetry of platform both sides, and the upper end of this two support body articulates one by one with the flat-bed both sides respectively, the middle part of this two support body or bottom pivot respectively are connected with supporting plate and closing plate, and supporting plate and articulate mutually by lower plate.

Two support bodies of said composition support, each side wing by the vertical turnover of a fagging and both sides thereof constitutes.

It vertically is associated with extension board in both sides in addition bendingly said platform, and the upper end of said two support bodies articulates one by one with the platform both sides respectively, is meant that the upper end of the side wing that above-mentioned and fagging links and the both sides of flat-bed extension board articulate one by one.

For so that this upper frame can be applicable to multiple height, the part that locating bush is positioned at above the platform has radial direction through hole, have some radial direction through hole of space on the push rod, and on support, be connected with a latch and be used to insert the through hole of differing heights of locating bush and push rod with fixed mandril through chain.

For further facilitate the height adjusting, can in the push rod upper axial be provided with negative thread, a screw arrangement is set in addition in this axial negative thread.

This jack stand is because its support is made up of two support bodies of symmetry, and the upper end of this two support body articulates one by one with the flat-bed both sides respectively, and the middle part of two support bodies or bottom pivot respectively are connected with supporting plate and closing plate, and this two plate articulates mutually.So, this jack stand non-working condition is tidied up when putting, can be through the supporting plate of mutual pivot joint and the closing plate angle that pivots, two support bodies are pivoted relative to each other to be drawn close, the volume of support is dwindled to greatest extent, and the shape that makes whole jack stand becomes smooth standardized, is convenient to place and take up space little.This jack stand is offered radial direction through hole on locating bush and push rod, its weight that is applicable to differing heights top is lifted; Push rod top is established negative thread and is disposed this jack stand of a screw rod, then can be fixed in conjunction with the pin of push rod differing heights through hole, and continuously change the top and lift height, it is particularly convenient to use.

Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.

Fig. 2 is this jack stand support body side direction diagrammatic sketch;

Fig. 3 is this jack stand support body front diagrammatic sketch;

Fig. 4 is this jack stand folded state diagrammatic sketch;

Fig. 5 is that this jack stand push rod is established negative thread and disposed the scheme drawing of screw rod.

Embodiment 1 jack stand has support 15, and its upper end is provided with platform 3; Support 15 is made up of two faggings 16 of symmetry, the fagging both sides are provided with the side wing 8 perpendicular to the fagging bending, side wing 8 upper ends articulate through the vertical curved down extension board 6 with the platform both sides of pivot 5, side wing 8 bottoms are connected with supporting plate 13 and closing plate 10 through pivot 149 pivots 9 pivots respectively, supporting plate 13 and closing plate 10 articulate mutually through pivot 12, and closing plate 10 upsides vertically are connected with baffle plate 11 with it; Platform 3 centers wear solid welding locating bush 19, and top, locating bush 19 lower ends is associated with locating plate 7 its other ends and is coupled to extension board 6; Be plugged with push rod 2 in the locating bush 19, locating bush 19 is positioned at that the position is provided with radial direction through hole above the platform, and the compartment of terrain is provided with some radial direction through hole 20 on the push rod 2; Be connected with chain 17 its other ends on the support 15 and be connected with the radial direction through hole that latch 18 can be interspersed in locating bush and push rod; The push rod upper end is provided with 1; Side wing 8 upper ends are provided with engaging tooth 4 is meshing with each other cooresponding wing plates on two sides upper end.

This jack stand can fold as shown in Figure 4, supporting plate 13 and closing plate 10 angles that pivot mutually wherein, and two faggings are corresponding to pivot according to pivot 5, draws close mutually, and jack stand duty volume is greatly reduced.

The jack stand of 2 examples of embodiment, as shown in Figure 5, its push rod 2 tops are provided with axial negative thread, and its formed screw break-through takes over a business 1, disposes screw rod 21 its upper ends in the screw and is associated with upper rminal disc 22.Other structure is identical with last example.
