[0015] The technical solution of the present invention will be further specifically described below with reference to embodiments and in conjunction with the accompanying drawings.

[0016] like Figure 1-3 As shown, a movable manual operation position box-type machine support leg includes a box-type machine 1 and a plurality of support leg bodies 2 connected to the bottom of the box-type machine 1. The support leg bodies 2 are symmetrically arranged on both sides of the box-type machine 1. The support leg bodies 2 include an upper support section 21 and a lower support section 22 connected to the bottom of the box-type machine 1 and movable up and down relatively. The bottom end of the lower support section 22 is provided with a universal wheel 3 with a brake. A connecting piece 23 is provided on the inner side of the bottom of the upper support section 21, and a screw 24 is provided on the inner side of the lower support section 22 that is threadedly connected to the connecting piece 23. The inner wall of the support section 22 is provided with a number of protrusions 221 distributed along the length direction, and the outer wall of the upper support section 21 and the bottom of one side of the lower support section 22 are provided with elastic sheets 211 that cooperate with and can contact the protrusions 221; the above-mentioned support leg bodies are symmetrically and evenly distributed at the bottom of the box-type machine. When the box-type machine needs to be moved, the box-type machine is moved with the support of the universal wheels, and then the brake can be locked to lock the position of the box-type machine. The two symmetrically arranged support legs are connected by a horizontal bar to enhance the supporting strength of the support legs.

[0017] The above-mentioned connecting piece is fixed on the side wall of the upper support section, and is movably connected and locked with the lower support section. The connecting piece is threadedly connected to the screw. When adjusting the height, the connecting piece and the upper support section can be driven up and down by rotating the screw to adjust the support leg, making the height adjustment of the support leg easier and more labor-saving. In the process of the screw rotating to move the connecting piece and the upper support section, the elastic sheet on the side wall of the upper support section contacts and passes over each protrusion in turn, so that the operator of the adjustment feels a sense of blockage, thereby accurately sensing the adjustment height of the upper support section, making the height adjustment of the upper support section more precise.

[0018] like Figure 2-3 As shown, the displacement of the elastic sheet 211 between each two protrusions 221 corresponds to the number of rotations of the screw 24, and several protrusions 221 are evenly distributed on the inner wall of the upper support section 21. The bottom end of the lower support section 22 is provided with a base plate 222 connected to the universal wheel 3, and the bottom end of the screw 24 is rotatably connected to the base plate 222. The side wall of the bottom end of the screw 24 is provided with a control nut 241 fixedly connected to the screw 24; the spacing between each two protrusions corresponds to the number of rotations of the screw, and each time the elastic sheet is displaced from between the two protrusions, the screw rotates a corresponding number of times. The ratio between the two can be adjusted and set according to actual needs to accurately determine the adjustment height of the support leg. During operation, the operator controls the rotation of the control nut so that the screw rotates as the control nut rotates.

[0019] like Figure 2 As shown, the connecting member 23 includes a connecting portion 231 threadedly connected to the screw rod 24 and a fixing portion 232 fixedly connected to the upper support section 21. A strip groove 223 is provided on the side wall of the lower support section 22 along the length direction. A bolt is provided in the strip groove 223 to connect with the fixing portion 232. A locking nut 242 is provided on the screw rod 24 corresponding to the upper portion of the connecting portion 231. A top plate 243 threadedly connected to the screw rod 24 is provided at the top of the screw rod 24. The bottom surface of the top plate 243 is connected to a screw threadedly connected to the screw rod 24. The telescopic spring 244, the bottom end of the telescopic spring 244 is in contact with the locking nut 242; the fixed part of the above-mentioned connecting piece is fixedly connected to the upper support section, and the movement of the fixed part can drive the upper support section to move. The screw is passed through the connecting part and the screw and the connecting part thread cooperate. The bolt passes through the strip groove and is locked with the connecting piece according to the height adjustment position of the upper support section, locking the relative position of the upper support section and the lower support section to ensure the structural stability of the upper support section and the lower support section, and strengthening the support strength and support stability of the support legs.

[0020] The above-mentioned top plate is threadedly connected to the top of the screw rod to facilitate quick disassembly and assembly of the structure. After the height adjustment is completed, the locking nut is rotated on the screw rod until the locking nut abuts and tightens the end face of the connecting part of the connecting piece, and the connecting piece is locked in a fixed position on the screw rod by the locking nut, thereby enhancing the structural stability between the connecting piece and the screw rod; after the top plate is removed from the screw rod, the telescopic spring leaves the screw rod with the top plate. When the top plate is tightened to the upper end of the top plate, the lower end of the telescopic spring contacts and abuts the locking nut. When the screw rod rotates, the connecting piece moves closer to or away from the top plate, and the telescopic spring always provides an acting force. When the connecting piece approaches the top plate, that is, when the upper support section is lifted, due to the weight of the box-type machine, the lifting burden of the upper support section is greater. At this time, the telescopic spring provides a contraction force to assist the upper support section in moving upward and lifting, making the lifting adjustment of the upper support section more labor-saving. When the connecting piece is away from the top plate, that is, when the upper support section is lowered, due to the weight of the box-type machine, the lowering burden of the upper support section is smaller, which is also more labor-saving.

[0021] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
