DETAILED DESCRIPTION
[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.
[0023] Example 1:
[0024] like Figure 1-5 As shown, the present invention proposes a traveling balancing structure for a flat bed for CT examination, which includes a bed body 1, a base 2 and a support platform. The lower end outer surface of the bed body 1 is fixedly connected to the support platform, and the end of the support platform away from the bed body 1 is fixedly connected to the base 2. A slot 3 is opened on the upper end outer surface of the bed body 1, and a bed board 4 is arranged inside the slot 3. A traveling mechanism 5 is arranged inside the slot 3. The bed body 1 corresponds to the CT machine. The patient lies flat on the surface of the bed board 4 and remains motionless, and then the traveling mechanism 5 drives the bed board 4 to push the patient to move toward the CT machine.
[0025] The travel mechanism 5 includes a slide 501, a slide plate 502, a movable groove 503, teeth 504, a motor 505 and a gear 506. The inner surface of the slot 3 is provided with a slide 501 near both sides, and the slide plate 502 is slidably connected to the inside of the slide 501. One end of the slide 501 is open. The two sets of slide plates 502 are fixedly connected to the bed board 4. The lower end outer surface of the bed board 4 is provided with a movable groove 503 near both sides. The inside of the two sets of movable grooves 503 is fixedly connected with several sets of teeth 504 at equal distances. The outer surface of both sides of the bed body 1 is provided with a motor 505 near one end, and the output end of the motor 505 passes through the slot 3. A gear 1 506 is fixedly connected to the interior of the slot 3. The gear 1 506 is located directly below the movable slot 503, and the gear 1 506 is meshed with the teeth 504. The output shaft of the motor 505 drives the gear 1 506 to rotate forward. Since the gear 1 506 is meshed with the teeth 504, the bed board 4 moves along the slide slot 501 toward the CT machine under the drive of the gear 1 506. When the output end of the motor 505 drives the gear 1 506 to rotate in the opposite direction, the bed board 4 moves toward the inside of the slot 3. A support mechanism 6 is provided inside the slot 3 between the two sets of gears 1 506. The support mechanism 6 enhances the stability of the bed board 4 during its movement.
[0026] Example 2:
[0027] like Figure 2-5 As shown, the difference between this embodiment and embodiment 1 is that the support mechanism 6 includes gear 2 601, support column 602 and ball 1 603; the lower side of the two groups of gear 1 506 are meshed with gear 2 601, and the interior of gear 2 601 is fixedly connected to the support column 602. During the forward rotation of gear 1 506, gear 2 601 drives the support column 602 to rotate, and the bottom end of the support column 602 passes through gear 2 601 and is rotatably connected to the slot 3. A rolling groove is provided on the outer surface of the upper end of the support column 602, and ball 1 603 is rollingly connected to the inside of the rolling groove. The outer surface of ball 1 603 is tightly fitted with the outer surface of the bed body 1, which provides support for the bed board 4 to improve its balance ability while reducing wear.
[0028] The outer surfaces of the two groups of support columns 602 are both provided with threads at the position above the gear 2 601. The threads on the outer surfaces of the two groups of support columns 602 rotate in opposite directions. When the two groups of threaded columns 605 rotate in opposite directions, a connecting plate 604 is threadedly connected between the two groups of support columns 602. The outer surface of the connecting plate 604 away from the two groups of support columns 602 is threadedly connected with a threaded column 605 at one end. During the rotation of the support columns 602 and the threaded column 605, the connecting plate 604 can be driven to move up and down. The two groups of threaded columns 605 correspond one-to-one to the two groups of support columns 602. The bottom end of the threaded column 605 is rotatably connected to the slot 3, and its top end passes through the connecting plate 604 and is embedded with a rolling connection of ball roller 2. The outer surface of ball roller 2 is tightly fitted with the outer surface of the bed board 4.
[0029] The outer surfaces of the two groups of support columns 602 are fixedly connected to the drive ring 606 at the position below the gear 2 601, and the outer surface of the threaded column 605 is fixedly connected to the transmission ring 607 at the position corresponding to the drive ring 606. A conveyor belt 608 is connected for transmission between the drive ring 606 and the transmission ring 607 located on the same side. The threads on the outer surfaces of the two groups of threaded columns 605 have opposite rotation directions. The gear 2 601 drives the support column 602 to rotate. Under the action of the support column 602, the drive ring 606 drives the conveyor belt 608 to drive the transmission ring 607 and the threaded column 605 to rotate, and the connecting plate 604 moves along the limiting column 610 toward the direction close to the bed board 4.
[0030] A movable hole 609 is provided near the middle of the outer surface of the upper end of the connecting plate 604, and the movable hole 609 is internally movably connected to a limiting column 610. One end of the limiting column 610 is fixedly connected to the slot 3, and the other end passes through the movable hole 609 and is embedded in a rolling connection with a ball three 611, and the outer surface of the ball three 611 is tightly fitted with the outer surface of the bed board 4.
[0031] Example 3:
[0032] like Figure 2-4 As shown, the difference between this embodiment and embodiment 1 and embodiment 2 is that two sets of support members 7 are hinged on the outer surface of the upper end of the connecting plate 604 near both sides, and one end of the support member 7 is hinged to the connecting plate 604, and the other end is hinged to the bed board 4, and a connecting hole 8 is provided on the inner surface of the slot 3 near one end of the motor 505 and at a position corresponding to the support member 7, and the cross-section of the connecting hole 8 is U-shaped.
[0033] The support member 7 includes a movable plate 701, a support plate 702, a spring 703, an elastic sheet 704 and a mounting groove 705; one end of the movable plate 701 is hinged to the connecting plate 604, and the other end is provided with a support plate 702, and a mounting groove 705 is provided at the position corresponding to the support plate 702 and the movable plate 701. When the bed plate 4 moves toward the direction close to the machine body, the support plate 702 moves along the movable plate 701 under the pull of the bed plate 4, and the movable plate 701 and the support plate 702 rotate adaptively. The rise of the connecting plate 604 provides sufficient rotation space for the movable plate 701 to prevent the movable plate 701 from getting stuck, and the support plate 702 moves with the bed The movement of plate 4 can provide support for the end of the bed plate 4 away from the bed body 1. A spring 703 is provided inside the mounting groove 705, and the end of the support plate 702 away from the connecting plate 604 passes through the interior of the mounting groove 705 and is fixedly connected to the spring 703. One end of the spring 703 is fixedly connected to the support plate 702, and the other end is fixedly connected to the mounting groove 705. An elastic sheet 704 is provided on the outer surface of the lower end of the movable plate 701 away from the end of the support plate 702, and one end of the elastic sheet 704 is fixedly connected to the connecting plate 604, and the other end is fixedly connected to the movable plate 701, thereby reducing the impact of vibration on the equipment during use.

[0036] Step 2: The output shaft of the motor 505 drives the gear 1 506 to rotate forward. Since the gear 1 506 is meshed with the teeth 504, the bed board 4 moves along the slide 501 toward the CT machine under the drive of the gear 1 506. When the output end of the motor 505 drives the gear 1 506 to rotate backward, the bed board 4 moves toward the inside of the slot 3, thereby realizing the automatic movement of the bed board 4.
[0037] 602 and the support plate 702 are connected, and the support plate 702 is connected to the support plate 701 by the spring 610. When the spring 610 is in the working state, the support plate 702 is connected to the support plate 701 by the spring 610. When the spring 610 is in the working state, the support plate 702 is connected to the support plate 701 by the spring 610. When the spring 610 is in the working state, the support plate 702 is connected to the support plate 701 by the spring 610. When the spring 610 is in the working state, the support plate 702 is connected to the support plate 702 by the spring 610.
