The radio frequency treatment bed adopts a push structure and is driven by an electric method, which saves manpower, and adopts a bed head lifting structure, which can lift the bed head to adjust the position and is suitable for different treatment environments.

[0004] However, the above-mentioned bedside lifting structure pushes the middle push rod bracket B forward through the movable end of the head-lifting motor, pushes the hinge A to move, and under the action of the rotating bracket B, drives the bed surface B to move, completes the lifting and limits the position; when the human body lies on the bed surface B in the lifted state, the weight of the human body is borne by the pushing hinge, the rotating bracket and the head-lifting motor. The head-lifting motor is subjected to great pressure, and when one of the components is damaged, the bed surface B will fall rapidly, which is not conducive to the treatment of the patient.

DETAILED DESCRIPTION

[0025] 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.

[0026] Example:

[0027] See also Figures 1 to 7 , the utility model provides a technical solution:

[0028] A bed board motion bracket comprises a bed board bracket 1, a pushing device 2 and a bed head lifting device 3, wherein the pushing device 2 is arranged on the upper surface of the bed board bracket 1, and the bed head lifting device 3 is arranged on the upper surface of the pushing device 2;

[0029] The bedside lifting device 3 includes a bed surface 4 and a bed surface mounting frame 5, one end of the bed surface 4 and the bed surface mounting frame 5 are rotatably connected by a hinge 7, a support frame 6 is arranged between the bed surface 4 and the bed surface mounting frame 5, one end of the support frame 6 is rotatably connected to the bottom of the bed surface 4, and the support frame 6 and the bottom of the bed surface 4 are both provided with mounting ears 17, which are rotatably connected through the mounting ears 17, and the mounting ears 17 are multiple and are respectively installed on the support frame 6 and the bottom of the bed surface 4, and the other end is movably connected to the bed surface mounting frame 5, and the bed surface mounting frame 5 is arranged on the upper surface of the bed board 8, and the upper surface of the bed board 8 is close to the bed board 8. A motor 9 is provided near the hinge 7, and the output end of the motor 9 is connected to the push plate 11 through a screw rod 10. The screw rod 10 is fixed to the upper surface of the bed board 8 through connecting seats 18 at both ends, and the screw rod 10 is rotatably connected to the connecting seat 18, and the screw rod 10 passes through the push plate 11 and is threadedly matched with the push plate 11. The rotation of the motor 9 drives the push plate 11 to move on the screw rod 10, and the push plate 11 pushes one end of the support frame 6 that is movably connected to the bed surface mounting frame 5, so that the end of the support frame 6 that is rotatably connected to the bed surface 4 rises, driving the bed surface 4 to rotate relative to the bed surface mounting frame 5 with the hinge 7 as the midline point.

[0030] Specifically, one end of the bed surface mounting frame 5 is open, and a sliding groove 12 is arranged inside the bed surface mounting frame 5 , and both ends of the push plate 11 and one end of the support frame 6 away from the bed surface 4 are arranged in the sliding groove 12 .

[0031] Specifically, one end of the support frame 6 away from the bed surface 4 is set in the sliding groove 12 through a roller 13, and the roller 13 is rotatably connected to the support frame 6. The roller 13 is installed on the outside of the support frame 6. The roller 13 is set on the inside of the folded edge 19 and is limited by the folded edge 19.

[0032] Specifically, the push plate 11 is slidably arranged in the sliding groove 12 through rollers 15, and an upward folded edge 19 is provided on the outer side of the sliding groove 12. Grooves 14 adapted to the folded edges 19 are provided near the two ends of the push plate 11. The folded edge 19 is chamfered on the side opposite to the groove 14 to facilitate the push plate 11 to slide relative to the folded edge 19 through the groove 14. The rollers 15 are symmetrically arranged on the top and bottom surfaces of the push plate 11 and are rotatably connected to the push plate 11. After the rollers 15 are installed, they contact the upper and lower walls of the sliding groove 12. The push plate 11 is guided and limited by the groove 14 and the folded edge 19.

[0033] Specifically, a crossbeam 16 is provided at the end of the groove 14 on the inner side of the bed surface mounting frame 5, and the height of the crossbeam 16 is lower than the height of the support frame 6, and the end of the support frame 6 away from the push plate 11 is placed on the upper end of the crossbeam 16. There is a certain angle between the support frame 6 and the bed surface mounting frame 5, which facilitates the support frame 6 to be lifted upward away from the push plate 11 end, and at the same time serves as the lower limit when the support frame 6 is lowered.

[0034] Specifically, the end of the support frame 6 that contacts the push plate 11 is arc-shaped and is on the same center line as the center of the roller 13. The diameter of the arc-shaped end of the support frame 6 is larger than the diameter of the roller 13. The arc-shaped design of the support frame 6 facilitates the movement of the support frame 6 relative to the bed mounting frame 5 and the rotation relative to the push plate 11. The push plate 11 pushes the push plate 11 to move by contacting the arc segment of the push plate 11.

[0035] Specifically, there is a gap between the push plate 11 and the top of the bed surface mounting frame 5 and the bed board 8 , and when the push plate 11 slides relative to the bed surface mounting frame 5 , no friction is generated between the push plate 11 and the bed board 8 .

[0036] During the use of the utility model, when it is necessary to lift, the bed plate bracket 1 can be used for lifting. When the treatment bed needs to be pushed into the radio frequency treatment machine, the bed plate 8 is moved by the pushing device 2. When the head of the bed needs to be lifted to adjust the treatment position, the motor 9 is started, and the screw rod 10 fixedly connected to the output end of the motor 9 rotates along with the output end of the motor 9. When the screw rod 10 rotates clockwise, the push plate 11 threadedly matched with the screw rod 10 moves toward the support frame 6. The push plate 11 is connected to the roller 15 in the sliding groove 12. The sliding groove 12 is moved, and the groove 14 and the folded edge 19 cooperate to guide and limit. After the push plate 11 contacts one end of the arc of the support frame 6, the arc of the support frame 6 is pushed to slide in the sliding groove 12 through the roller 13, so that the end of the support frame 6 that is rotatably connected to the bed surface 4 rises, driving the bed surface 4 to rotate relative to the bed surface mounting frame 5 with the hinge 7 as the midline point, thereby realizing the lifting of the bed surface 4; when lowering the bed surface 4, it is only necessary to run the motor 9 in the reverse direction to rotate the screw rod 10 counterclockwise to realize the resetting of the bed surface 4.

[0037] The remaining undescribed parts of the present invention may be the same as the prior art, or are well-known technologies, or may be implemented by using the prior art, and will not be described in detail here.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
