Claims

[Claims for Utility Model Registration] (1) A support leg lifting mechanism for a trailer for lifting and lowering a support leg that is supported by a support part provided on the trailer so as to be able to rise and fall along the vertical direction, comprising: a first rack member that is integrally attached to the support leg and extends along the vertical direction from at least the middle portion in the vertical direction to the lower end; and a first rack member that is integrally attached to the support leg in parallel with the first rack member; a second rack member that extends along the vertical direction from the vertically intermediate portion to the upper end; a drive shaft to be driven; a large-diameter first pinion gear coaxially fixed to the drive shaft and capable of meshing with the first rack member; a small-diameter second pinion gear coaxially fixed to the shaft and capable of meshing with the second rack member, the first pinion gear and the first rack member meshing with each other; By rotating this handle, the support leg can be raised and lowered at high speed and with low torque, and the handle is moved along the axial direction to mesh the second pinion gear and the second rack member with each other. The trailer support leg lifting mechanism is characterized in that the support leg can be raised and lowered at low speed and high torque by rotating the handle. (2) Utility model registration claim 1, characterized in that the upper end of the first rack member and the lower end of the second rack member are set to overlap in the lateral direction. The trailer support leg lifting mechanism described in . (3) First and second through holes for position fixing are formed in the upper and lower parts of the support leg, respectively, and the support part selectively communicates with the first and second through holes. A position fixing hole is formed, and the position fixing member is inserted through the first through hole and the position fixing hole in communication with each other, so that the support leg is fixed at the lower position, and the second through hole is fixed to the lower position. Utility model registration claim No. 1, characterized in that the support leg is fixed in an upper position by inserting a position fixing member into the through hole and the position fixing hole in communication with each other. The trailer support leg lifting mechanism according to item 2. (4) The lower end of the support leg is lifted above the road surface when the support leg is fixed at the upper position, and the lower end of the support leg engages with the road surface when the support leg is fixed at the lower position. A support leg elevating mechanism for a trailer according to claim 3 of the utility model registration claim.
