The structure is light, firm, flexible and reliable, and can be carried and operated by one person.
However, in the existing horizontal jack, the contact area between the device and the ground is reduced due to the fact that the wheels are too small, so that when the jack is used on soft ground, the wheel cannot support the jack due to the fact that the reaction force is too small and the wheels are too small, the jack is sunk, and accordingly the jack is unstable to lift and inconvenient to use; in addition, after the wheel is sunk, a reaction force is formed by the contact of the wheel and the ground, and the reaction force acts on the sheet metal part or the connecting rotating shaft for fixing the wheel, so that the sheet metal part or the connecting rotating shaft is deformed after long-term use; thereby influencing the movement of the jack and reducing the service life of the sheet metal part or the connecting rotating shaft; when the wheels are completely sunk into the ground, the working is continued, so that devices at the bottom of the jack, particularly oil pump components, are polluted; after sinking, the jack cannot normally perform pressure relief and resetting actions; most important is the reduced safety;
when the vehicle is maintained and meets the vehicle with a higher chassis, the standard jack cannot lift the vehicle or the lifting height is insufficient, so that the maintenance is inconvenient, and the lifting height is increased by arranging a screw rod between the tray and the bracket in the prior art, but the heights of the tray and the bracket and the distance between the bracket and the telescopic rod are limited, and the diameters of middle threaded holes of the tray and the bracket are limited; the length and the diameter of the screw rod are limited, so that the following technical problems are caused, 1. When the whole screw rod extends out, the screw rod is limited in length, so that the jack cannot lift a vehicle with a higher chassis or the lifting height is insufficient; in addition, the whole screw rod can cause the screw rod to be connected with the thread structure of the tray only after extending out, so that the bearing capacity is reduced. 2. Through threaded rod height-adjusting, need screw out support and tray with threaded rod round by round earlier through the instrument when using to vehicle rescue efficiency has been influenced.
In order to solve the technical problems, the invention provides an heightening anti-sinking horizontal jack.

Referring to fig. 1, 2, 5 and 6, the first tray 7 is provided with a protruding block 701, a groove 702 is formed between the protruding blocks, and a fastening groove 703 is disposed below the protruding block 701; the base 201 is provided with a clamping key 208 matched with the clamping groove 702, and the base 201 is clamped in the clamping groove below the projection 701 through the clamping key 208 and is fixed on the first tray 7; the jack body 1 is also provided with a positioning plate 8 for fixing the height-increasing device part 2; the positioning plate 8 is a positioning plate 8 provided with a bolt fixing hole or a positioning plate 8 with the same structure as the first tray.
Referring to fig. 2, the jack body 1 is further provided with a connecting shaft 102 for connecting the supporting wheels 21.
In the using process of the jack, if a lower chassis vehicle is lifted, an heightening device part is not required to be installed; when a higher chassis vehicle is lifted, the clamping key on the base of the heightening device component is aligned with the groove on the first tray, and then the heightening device component is rotated to enable the clamping key to be placed in the clamping groove below the protruding block, so that the heightening device component is fixed on the first tray; then the telescopic length of the regulating pipe is regulated according to the height of the chassis; after the adjusting pipe is adjusted, the lifting hand is operated to enable the oil pump component to act to drive the lifting arm and the heightening component to ascend, so that the jacking disc is jacked on the chassis of the vehicle, the vehicle is jacked for maintenance, and after the maintenance is finished, the jack is decompressed, and the jack is reset; and after resetting, rotating the heightening device part to enable the clamping key to rotate at the groove position, then taking down the heightening device part, retracting the adjusting tube into the supporting tube, positioning by using the bolt part, and then fixing on the positioning plate.
When the jack works on soft ground and the wheels sink, the wheels are heightened, so that the contact area with the ground is enlarged, and the jack body is supported in the first step; in order to reduce the bearing force of the reaction force of the wheels, when the heightened wheels sink to the supporting bottom plate to be in contact with the ground, the supporting bottom plate further increases the contact area with the ground, plays a role of supporting the jack body in the second step, reduces the bearing force of the heightened wheels on the reaction force, and accordingly prevents the problem that the reaction force acts on the connecting rotating shaft, and avoids the problem that the deformation of the connecting rotating shaft is caused to influence the movement of the jack in the later period after long-term use; the supporting bottom plate arranged at the bottom prevents the jack from polluting devices at the bottom of the jack after sinking, and also avoids the problem that the jack cannot normally perform pressure relief reset action after sinking, thereby ensuring the stability of the vehicle during lifting; the safety performance in use is improved;
the telescopic height of the adjusting pipe is controlled by the adjusting pipe and the supporting pipe through the positioning holes and the adjusting holes by the bolt pieces, and the telescopic height of the adjusting pipe is controlled by the adjusting pipe and the adjusting pipe through the adjusting holes by the bolt pieces, so that the problem that a vehicle with a higher chassis cannot be lifted or the lifting height is insufficient due to the fact that the heights of the tray and the bracket and the distance between the bracket and the telescopic rod are limited and the diameters of middle threaded holes of the tray and the bracket are limited is avoided; in addition, the adjusting time of the telescopic height of the heightening device part is reduced, so that the working efficiency is improved, and the maintenance speed of the vehicle is accelerated;
through cooperation between draw key and recess, lug and the buckle groove to make things convenient for the height-increasing ware part to fix on first tray, and then realize quick dismouting height-increasing ware part.
When the invention is not applicable to the heightening device, two fixing modes of the heightening device are adopted, one is that the heightening device is connected with the heightening device through bolts penetrating through the positioning plate, so that the positioning of the heightening device is completed; the other is that the structure of the positioning plate is the same as that of the first tray, and the positioning of the heightening device component is completed through the matching of the clamping key, the groove, the convex block and the clamping groove; the second positioning plate is connected and fixed with the jack body by bolts penetrating through the middle.
The invention avoids the technical problem that the jack body sags when working on soft ground, solves the technical problem that the lifting height of the high chassis vehicle is insufficient and the maintenance is inconvenient, thereby improving the use safety of the jack.
The above embodiments are illustrative of the present invention, and not limiting, and any simple modifications of the present invention fall within the scope of the present invention.
