DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1-Figure 2 As shown, a machine tool support leg includes a support frame 2 and a lifting frame 3, as shown in FIG. Figure 4 As shown, the support frame 2 includes a support block 201 and a bottom plate 204. The upper end of the support block 201 is provided with a bolt hole 101, and the support block 201 can be connected to the machine tool by bolts. The two ends of the support block 201 are connected to the bottom plate 204 through side plates 203, and the rear ends of the two side plates 203 are connected through a rear plate 207. The front ends of the two side plates 203 are open structures; Figure 5 As shown, the lifting frame 3 includes a parallel upper top plate 303 and a lower top plate 301, wherein the upper top plate 303 is located between the support block 201 and the bottom plate 204, and the lower top plate 301 is located below the bottom plate 204. The bottom plate 204 is provided with a guide hole 206, and the upper top plate 303 and the lower top plate 301 are connected by a guide rod 302 matched with the guide hole 206, as shown in FIG. Figure 3 As shown, a second adjusting bolt 6 runs through the upper top plate 303, and the second adjusting bolt 6 is threadedly matched with the upper top plate 303. The second adjusting bolt 6 is pressed against the bottom of the support block 201. Rotating the second adjusting bolt 6 can drive the lifting frame 3 to move up and down to achieve height adjustment.

[0025] The bottom of the lower top plate 301 is provided with anti-skid grooves, which can increase friction and improve the stability of the machine tool.

[0026] A shock-absorbing pad 1 is provided at the upper end of the support block 201 . The shock-absorbing pad 1 is located between the support block 201 and the machine tool and can play a shock-absorbing role.

[0027] A spring 4 is connected between the upper top plate 303 and the bottom plate 204. An upper positioning column 304 cooperating with the spring 4 is provided at the bottom of the upper top plate 303, and a lower positioning column 205 cooperating with the spring 4 is provided at the upper end of the bottom plate 204. Under the elastic force of the spring 4, the lifting frame 3 can be pushed upward. The spring 4 and the second adjusting bolt 6 act in opposite directions, which can improve the stability of the lifting frame 3.

[0028] A support plate 202 is provided on the side wall of the rear plate 207, and a moving wheel 5 is provided below the support plate 202. A wheel seat 501 is connected to the outer side of the moving wheel 5. The wheel seat 501 is a right-angle plate structure. The wheel seat 501 is tightly attached to the rear plate 207. A first adjusting bolt 502 rotatably connected to the falling wheel seat 501 is connected to the support plate 202. A shaft sleeve is provided at the upper end of the wheel seat 501. The lower end of the first adjusting bolt 502 is rotatably matched with the shaft sleeve. The first adjusting bolt 502 is threadedly matched with the support plate 202. Rotating the first adjusting bolt 502 can drive the wheel seat 501 to rise and fall, thereby realizing the height adjustment of the moving wheel 5.

[0029] The length of the first adjusting bolt 502 is greater than that of the guide rod 302, so as to ensure that the moving wheel 5 can be supported on the ground after the lower top plate 301 moves downward to the maximum position.

[0030] During use, when the supporting feet are suspended in the air and cannot touch the ground, the second adjusting bolt 6 can be rotated to drive the lower top plate 301 to move downward so that the lower top plate 301 is supported on the ground; when the machine tool needs to be moved, the first adjusting bolt 502 can be rotated to support the moving wheel 5 on the ground, so that the lower top plate 301 is suspended in the air, and the machine tool is supported by the moving wheel 5, which facilitates the movement of the machine tool.

[0031] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
