[0027] A moving seat 320 for cooperating with the moving assembly 002 to control the angular change of the connecting rod 310 is movably installed at the upper end of the connecting rod 310. There are two moving seats 320. The moving seat 320 includes a lead screw nut 321. A connecting block 1 322 is fixedly installed at the lower end of the lead screw nut 321. A limiting hole 1 323 for cooperating with the pin shaft 311 to limit the connecting rod 310 is opened in the middle of the connecting block 1 322, and the pin shaft 311 is located in the hole cavity of the limiting hole 1 323.

[0028] A limit frame 324 is fixedly installed at the upper end of the lead screw nut 321. A ball 325 is movably installed at the upper end of the limit frame 324 to facilitate the left - and - right movement of the lead screw nut 321. Through the arrangement of the ball 325, it is convenient for the lead screw nut 321 to move left and right, avoiding the situation that the steam boiler body 100 is too heavy and the lead screw nut 321 is difficult to slide left and right. One end of the limit frame 324 is fixedly installed with a sealing plate 326 for limiting the ball 325 through bolts.

[0029] A reciprocating lead screw 330 for controlling the left - and - right movement of the moving seat 320 is installed in the middle of the moving seat 320. Helical grooves with opposite helix directions are machined at both ends of the reciprocating lead screw 330 to facilitate the left - and - right sliding of the two lead screw nuts 321.

[0030] A worm 340 for controlling the rotation of the reciprocating lead screw 330 is installed at the right end of the reciprocating lead screw 330. A worm gear 331 for meshing with the worm 340 is fixedly installed at the right end of the reciprocating lead screw 330.

[0031] A rotating rod 341 is fixedly installed in the middle of the worm 340. A handwheel 342 for facilitating the rotation of the rotating rod 341 is fixedly installed at the front end of the rotating rod 341. And the handwheel 342 provided by the present utility model can also be selected as a motor. By rotating the handwheel 342, the worm 340 drives the worm gear 331 to rotate synchronously, and the reciprocating lead screw 330 drives the two moving seats 320 to move in the opposite direction synchronously to adjust the lifting of the moving component 002.

[0032] The adjusting component 300 includes a limit block 350 for limiting the reciprocating lead screw 330 and the worm 340. A square cavity for limiting the moving seat 320 is formed in the middle of the limit block 350, enabling the moving seat 320 to slide left and right without rotation. And an arc - shaped cavity is machined at the upper end of the cavity to facilitate the rolling of the ball 325.

[0033] The support base 001 includes a bottom plate 200. The bottom plate 200 is fixedly installed at the bottom of the steam boiler body 100. Support legs 210 for supporting the steam boiler body 100 are fixedly installed at the edges of the bottom plate 200. And the adjusting component 300 is fixedly installed in the middle of the bottom plate 200. The upper end of the limit block 350 is closely attached to the bottom wall of the steam boiler body 100.

[0034] The moving component 002 includes a support plate 400. Four universal wheels 410 for facilitating the movement of the steam boiler body 100 are installed at the lower end of the support plate 400. A second connecting block 420 for limiting the connecting rod 310 is fixedly installed at the upper end of the support plate 400. A second limiting hole 421 for limiting the pin shaft 311 is formed in the middle of the second connecting block 420. Four fixing rods 430 for cooperating with the limiting cylinder 110 to limit the support plate 400 are fixedly installed at the upper end of the support plate 400, and the fixing rods 430 are telescopic inside the limiting cylinder 110, so that when the steam boiler body 100 is moved, the connecting rod 310 is not easily damaged, and the cooperation of the fixing rods 430 and the limiting cylinder 110 makes the movement of the steam boiler body 100 more stable.

[0035] When the steam boiler body 100 is moved, by rotating the hand wheel 342, the rotating rod 341 drives the worm 340 to rotate synchronously, so that the worm wheel 331 drives the reciprocating lead screw 330 to rotate. The lead screw nuts 321 at the left and right ends of the reciprocating lead screw 330 move away from each other, so that the two connecting rods 310 change their angles and drive the support plate 400 to move downward, so that the universal wheels 410 are in contact with the ground. Continuing to rotate the hand wheel 342, after the support legs 210 are away from the ground, the steam boiler body 100 can be moved. After the position adjustment of the steam boiler body 100 is completed, reverse-rotate the hand wheel 342 so that the support legs 210 support the steam boiler body 100.
