Abstract

The utility model relates to a multipurpose pressure rod for a hydraulic rack matched with a car. The existing pressure rod has single function. The structure of one end of the round rod in the pressure rod is identical with the structure of the corresponding part of the common pressure rod, and the other end is provided with a socket wrench. The axial line of the wrench end takes a cut angle which is larger than 90 DEG and smaller than 180 DEG with the axial line of the round rod. The wrench and the round rod can be fastened and connected timelessly and can be connected in exchangeable way, so as to exchange wrenches with different standards according to the sizes of the screw bolts. The utility model has advantages of being used as the pressure rod for the hydraulic rack and being the socket wrench used for repairing cars. The pressure rod has more labor saving and quickness than common socket wrenchs, in the condition of not influencing the function of the pressure rod of the hydraulic jack.

Description

Multipurpose pressure rod for hydraulic rack

The utility model is the press rods on the hydraulic jack with the automobile adapted.

Press rods on the existing hydraulic jack, its function only limit to when making when jack-uping weight, with its ceaselessly motion up and down, and with weight jack-up, i.e. an only mono-leverage.On the other hand, during at the repairing automobile, as the bolt on the loading and unloading wheel, need be equipped with and use special sleeve spanner separately.

The purpose of this utility model is to provide a kind of hydraulic jack that serves many purposes very useful press rods, and it is the press rods of jack, can use as the sleeve spanner again.

Structure of the present utility model is as follows: the structure of the structure of a round bar one end and known jack usual pressure bar corresponding site is identical, and the other end of round bar has the head of removing of sleeve spanner, and axis and the round bar axis of removing head end are greater than 90 degree less than the 180 degree angles of cut.

When the utility model used as the Hydraulic Jack bar, using method was the same with common Hydraulic Jack bar.After automobile is by jack stand, can takes off press rods, remove the end dismounting of head and the bolt on the installation wheel with this press rods band sleeve spanner.The general sleeve spanner of the utility model is long, and is more laborsaving when therefore loading and unloading wheel.Because axis and round bar axis that the utility model is removed head end are certain angle of cut, can avoid boss on the wheel when therefore being used to load and unload wheel and continuous rotation significantly, loading and unloading are quick.

The axis that the utility model is removed head end preferably is 120 ± 5 with the round bar axis and spends the angles of cut.The endoporus of removing head can be made into plum blossom shape, hexagonal shape or other shapes.Remove head and can make the plurality of specifications that varies in size as required, remove between head and round bar and can be made into permanent fastening the connection, also can be made into the interchangeable formula connect, with can be by the head of removing of bolt size transposing different size.

Compare with prior art, the utility model has the advantages that both can make the Hydraulic Jack bar uses, and can repair the sleeve spanner of automobile again, one-object-many-purposes; And under the condition that does not influence Hydraulic Jack bar function, more more laborsaving, quick than ordinary cartridge spanner.

Fig. 2 be among Fig. 1 E to view.

Fig. 3 be among Fig. 1 D to view.

Embodiment: see Fig. 1-3.The axis of garden bar 1 is the 120 degree angles of cut with an axis of removing 2, and removing an endoporus of 2 is the plum blossom shape.3 is pin among the figure.Removing an external diameter of 2 is 30 millimeters, and length is 26 millimeters.The press rods total length is 500 millimeters.Removing head is connected by welding with round bar.

Claims

1, a kind of hydraulic jack is used press rods at most, it is characterized in that: the structure of the structure of a round bar one end and known jack usual pressure bar corresponding site is identical, and the other end of round bar has the head of removing of sleeve spanner, and axis and the round bar axis of removing head end are greater than 90 degree less than the 180 degree angles of cut.

2, use press rods at most as the said hydraulic jack of claim 1, it is characterized in that: axis and the round bar axis of removing head end are 120 ± 5 degree angles of cut.
