Abstract
A trailer jack capable of quickly adjusting height is characterized in that an axial long guide plate is arranged on the side surface of the periphery of an outer pipe, and a plurality of locking holes are longitudinally arranged on the guide plate; the guide plate is provided with a sliding frame which is fixedly connected with a trailer connection plate, supporting plates extending out along the radial direction of the outer tube are respectively reserved at the upper end and the lower end of the sliding frame, the outer sections of the upper supporting plate and the lower supporting plate are bent for 90 degrees relatively, a U-shaped handle is arranged between the outer sections of the two supporting plates, two fork rods of the handle inwards penetrate through the outer sections of the two supporting plates respectively, a spring is arranged on the periphery of the handle fork rod at the inner side of the outer section of the supporting plate, a check ring is arranged on the handle fork rod at the inner side of the spring, and the. The problem that the supporting point height is adjusted through the lead screw by shaking the crank, and the speed is low is solved, and the lifting jack is particularly suitable for being carried and used by a trailer.
Description
Technical Field
The utility model discloses the jack relates to trailer maintenance lifting machinery, and specifically speaking is a conveniently adjust and lift some from trailer jack of strong point height.
Background
Present portable trailer jack all is at the lateral surface installation trailer connecting plate of outer tube, trailer connecting plate and trailer fixed connection, and during the use, becomes vertical through trailer connecting plate adjustment jack outer tube, inner tube, and the removal wheel of inner tube lower extreme lands and makes the strong point, because the geographical position difference of locating, removes the wheel and apart from the strong point too big or too little, need wave the crank in advance and adjust, and speed is slow, takes a lot of work and time.
Disclosure of Invention
The utility model discloses a solve trailer jack, by waveing the crank and passing through lead screw adjustment strong point height, the slow problem of speed has designed one kind and has utilized the trailer jack that baffle slide adjustment supported height.
The technical scheme of the utility model is that a trailer jack capable of quickly adjusting height comprises an inner tube, an outer tube, a crank, a movable wheel and a trailer connecting plate, wherein the inner tube is sleeved in the outer tube;
it is characterized in that the side surface of the outer periphery of the outer tube is provided with an axial long guide plate, and a plurality of locking holes are longitudinally arranged on the guide plate;
the guide plate is provided with a sliding frame which is fixedly connected with a trailer connection plate, supporting plates extending out along the radial direction of the outer tube are respectively reserved at the upper end and the lower end of the sliding frame, the outer sections of the upper supporting plate and the lower supporting plate are bent for 90 degrees relatively, a U-shaped handle is arranged between the outer sections of the two supporting plates, two fork rods of the handle inwards penetrate through the outer sections of the two supporting plates respectively, a spring is arranged on the periphery of the handle fork rod at the inner side of the outer section of the supporting plate, a check ring is arranged on the handle fork rod at the inner side of the spring, and the.
When the device is used, the outer pipe and the inner pipe are made to be vertical by fixedly connecting the trailer connecting plate with the trailer, the handle is pulled to drive the retaining ring to compress the spring, the top end of the handle fork rod is pulled out of the locking hole, the guide plate and the sliding frame are matched to adjust the outer pipe, the moving wheel is made to directly contact with the supporting point, the handle is loosened, the spring pushes the retaining ring to drive the top end of the handle fork rod to be embedded into another group of locking holes for locking, then the crank is shaken, the outer pipe is driven to lift by matching the lead screw and the inner pipe, and then the.
The technical effect of the utility model is that, adopt above-mentioned technical scheme, can realize a slide adjusting outer tube height, make the trailer jack who removes wheel quick contact strong point.
