[0009] Further, the main body frame is a hollow cuboid, and steel plates are welded on the upper and lower surfaces of the cuboid. Four omnidirectional lockable casters are installed at the four corners of the lower surface.

[0010] Further, bearing seats are welded above the left column and the right column respectively, which are used to be installed in cooperation with the cross beam of the corresponding I-shaped cage through cage bearings.

[0011] Furthermore, it is installed in cooperation with the bearing seat and the cage bearing through the square hole fixer to achieve 360° rotation after the chassis is installed and clamped.

[0012] Furthermore, the square hole fixer is installed in cooperation with the central axes of the bearing seat and the cage bearing in a pluggable manner.

[0013] Furthermore, pull out the square hole fixer to separate it from the cage bearing to achieve 360° flipping of the chassis. When fixing, press down the square hole fixer to cooperate with the cage bearing again.

[0014] Furthermore, the hand-operated locking and fixing device includes a handwheel, a round head screw, and a handwheel fixing block.

[0015] Furthermore, an internal thread is cut in the middle of the handwheel fixing block, and the round head screw is screwed into the handwheel fixing block from below, and the handwheel is installed above the round head screw.

[0016] Furthermore, a disc is welded below the round head screw for limiting the screwing in and out of the round head screw and fixing the chassis after installation and clamping.

[0017] The beneficial effects of the present invention are as follows:

[0018] The structure of the present invention is simple, the processing cost is low, and the operation is convenient; moreover, the chassis rotating bracket device can be fixed on the movable operating table, which is convenient for the handling operation of the product between the operating tables, improves the operation efficiency, and ensures the reliability of the product; the bracket device is not easy to deform, not easy to wear, and has a longer service life.

[0022] The following further describes the invention patent in conjunction with the drawings and embodiments.

[0023] As Figure 1 shown, a chassis rotating bracket device provided by the present invention includes a main body frame 1, a left column 2-1, a right column 2-2, a square hole fixer 3, a bearing seat 4, a handwheel 5, a handwheel fixing block 6, an I-shaped cage 7, a cage bearing 8, a round head screw 9, a handle fixer 10, a cage connecting rod 11, and an omnidirectional caster 12;

[0024] Among them, the main frame 1 is at the same height as the operating platform, enabling the handling between operating platforms. The main frame 1 is a hollow cuboid, with steel plates welded on the upper and lower surfaces of the cuboid, mainly realizing the overall load-bearing of the chassis and devices. Four lockable omnidirectional casters 12 are installed by drilling holes at the four corners of the lower bottom surface, which are used for the overall tooling load-bearing and movement; and because the main frame 1 is hollow, the internal space can be used for counterweight;

[0025] The left column 2-1 and the right column 2-2 are welded on the left and right sides of the upper surface of the main frame 1. A bearing seat 4 is welded above each column, and is respectively installed in cooperation with the cross beam of the corresponding I-shaped cage 7 through a cage bearing 8. Finally, the rotation direction of the I-shaped cage 7 is fixed by a square hole fixer 3. The square hole fixer 3 is installed in cooperation with the bearing seat 4 and the cage bearing 8. The left column 2-1, the right column 2-2, the bearing seat 4, and the I-shaped cage 7 on the main frame 1 can realize the cooperation with the chassis cage, realizing 360° rotation after the chassis is clamped. When in use, the product is loaded onto the chassis cage, and the product handle is fixed by the handle fixer 10. The manipulator wheel 5 is rotated, driving the disc head screw 9 to rotate, to fix the chassis. If the square hole fixer 3 is pulled out and separated from the cage bearing 8, the chassis can be flipped 360°. When fixing, press the square hole fixer 3 to cooperate with the cage bearing 8 again. The plugging and unplugging operation of the square hole fixer 3 realizes the fixation of the rotation angle, meeting the vertical and front and back flipping operations.

[0026] The hand wheel 5 is connected to the hand wheel fixing block 6 through the disc head screw 9. The hand wheel fixing block 6 is fixed at the head and tail ends of each vertical beam of the I-shaped cage 7, forming a hand-crank fixing device for fixing after the chassis is clamped, that is, each I-shaped cage 7 includes 4 hand-crank fixing devices. Specifically, an internal thread is cut in the middle of the hand wheel fixing block 6, and the disc head screw 9 is screwed into the hand wheel fixing block 6 from below. A disc is welded below the disc head screw 9, which is used for the limit of screwing in and out of the disc head screw 9 and the fixation after the chassis is clamped. The hand wheel 5 is installed above the disc head screw 9, forming a hand-crank locking and fixing device.

[0027] The I-shaped cages 7 corresponding to the two columns are symmetrically placed. Among them, the two vertical beams on the same side are connected by a cage connecting rod 11, and the two symmetrical vertical beams on the other side are left suspended without treatment. The handle fixer 10 is fixed at both ends of the cage connecting rod 11 by screws, which is used for fixing the handle of the front panel of the chassis, realizing the opening and closing assembly of the front panel of the chassis.

[0028] The specific embodiments described above further elaborate on the object, technical solution, and beneficial effects of the present invention. It should be understood that the above description is only for the specific embodiments of the present invention and is not intended to limit the present invention.
