Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, fig. 2 and fig. 3, the present invention provides a technical solution: automatic trailer lifting and supporting device, including hydraulic leg 1 and trailer body 6, the left end fixed mounting of hydraulic leg 1 has connecting plate 2, the leading flank left end fixed mounting of connecting plate 2 has riser 3, the left surface fixed mounting of riser 3 has diaphragm 4, the top of diaphragm 4 is equipped with round hole 5, the bottom of trailer body 6 is equipped with rectangle mouth 7, rectangle mouth 7 is used for holding diaphragm 4 isotructure, the roof fixed mounting of rectangle mouth 7 has screw rod 8, the spiro union has first nut 9 and second nut 10 on the screw rod 8, first nut 9 and second nut 10 laminate respectively in the top and the bottom of diaphragm 4, and then press from both sides the clamp with diaphragm 4 and fix.

Particularly, the inside wall left end of round hole 5 is equipped with rectangular hole 11, the setting of rectangular hole 11 for conveniently making 5 covers of round hole of diaphragm 4 establish on screw rod 8, if set up rectangular hole 11, first nut 9 can be the fixed ring body this moment, and inside wall fixed mounting saves the operating procedure on screw rod 8's lateral wall.

Particularly, the lateral wall bottom spiro union of screw rod 8 has internal thread ring 12, and the lateral wall of internal thread ring 12 is equipped with rotates 13, and the horizontal pole 14 is installed to the right-hand member that rotates 13, and the right-hand member fixed mounting of horizontal pole 14 has limiting plate 15, and the left surface laminating of limiting plate 15 is at the right flank of riser 3, rotates 13 and is used for connecting internal thread ring 12 and horizontal pole 14, also can make internal thread ring 12 and horizontal pole 14 take place relative rotation.
