[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0027] like Figures 1 to 6 As shown, an embodiment of the present invention provides an auxiliary positioning device for medical imaging examination, including an image detector 1, a horizontal mover 2 is fixedly connected to the right side of the image detector 1, a detection bed 3 is slidably connected above the horizontal mover 2, an adjustment structure 8 is rotatably connected below the detection bed 3, an L-shaped groove 10 is provided in the detection bed 3, a moving plate 14 and a moving plate 3 6 are slidably connected in the L-shaped groove 10, the adjustment structure 8 is connected to the moving plate 14, a self-locking structure 9 is provided on the back of the moving plate 14, the moving plate 14 is connected to the moving plate 3 6 through the self-locking structure 9, a moving plate 2 5 is slidably connected in the detection bed 3, the moving plate 2 5 is connected to the adjustment structure 8, and a fixing column 15 is fixedly connected below the moving plate 14;

[0028] By providing the L-shaped groove 10, when the moving plate 1 4 and the moving plate 3 6 are affected by thrust or tension, the moving plate 1 4 and the moving plate 3 6 will slide in the L-shaped groove 10, so that the L-shaped groove 10 plays a certain auxiliary role in the movement of the moving plate 1 4 and the moving plate 3 6, thereby avoiding the phenomenon of misalignment of the moving plate 1 4 and the moving plate 3 6 during movement.

[0029] The self-locking structure 9 includes a concave plate 901 and a connecting plate 902. The concave plate 901 is fixedly connected to the front of the moving plate 1 4. The connecting plate 902 is fixedly connected to the front of the moving plate 3 6. A plurality of arc blocks 903 are arranged above the connecting plate 902. A rotating rod 904 is rotatably connected to the top of the concave plate 901. A ratchet 905 is fixedly connected to the outer surface of the rotating rod 904. The ratchet 905 overlaps the arc block 903. A coil spring 906 is connected to the outer surface of the rotating rod 904. The ratchet 905 is connected to the image detector 1 through the coil spring 906.

[0030] By providing the coil spring 906, when the connecting plate 902 slides in the concave plate 901, the arc block 903 will contact the ratchet bar 905, and the ratchet bar 905 will drive the coil spring 906 to deform when turning over, so that the coil spring 906 plays a certain role in limiting the rotation of the ratchet bar 905, thereby preventing the ratchet bar 905 from getting stuck when rotating;

[0031] The fixed column 15 is clamped in the adjustment structure 8. The front of the image detector 1 is provided with a controller 11. The adjustment structure 8 includes a threaded rod 1 801, a threaded rod 2 802 and a motor 803. The threaded rod 1 801 is rotatably connected to the lower left side of the detection bed 3, and the threaded rod 2 802 is rotatably connected to the lower right side of the detection bed 3. The motor 803 is fixedly connected to the outside of the detection bed 3, and the output shaft of the motor 803 is connected to the threaded rod 2 802. The threaded rod 1 801 is externally transmission-connected with an anti-skid belt 804. The threaded rod 1 801 is connected to the threaded rod 2 802 through the anti-skid belt 804. The threaded rod 1 801 is externally threadedly connected with an auxiliary sleeve 1 805. The threaded rod 2 802 is externally threadedly connected with an auxiliary sleeve 2 806. The auxiliary sleeve 2 806 is connected to the movable plate 2 5. The fixed column 15 is clamped in the auxiliary sleeve 1 805, and the auxiliary sleeve 1 805 overlaps with the movable plate 1 4.

[0032] By setting the anti-skid belt 804, the motor 803 drives the second threaded rod 802 to rotate. Since the second threaded rod 802 is connected to the first threaded rod 801 through the anti-skid belt 804, the first threaded rod 801 and the second threaded rod 802 will rotate synchronously, and the auxiliary sleeve 1 805 and the auxiliary sleeve 2 806 will evenly move on the surface of the first threaded rod 801 and the second threaded rod 802, so that the moving plate 14 and the moving plate 2 5 can be at the same level after the position is adjusted, avoiding the phenomenon of tilting after the slot block 14 above the telescopic connecting belt 13 is engaged with the card slot 12;

[0033] A clamping structure 7 is fixedly connected to one side of the moving plate 14, and the clamping structure 7 is clamped in the fixed column 15. A telescopic connecting belt 13 is provided in the moving plate 14, and a slot block 14 is fixedly connected to one end of the telescopic connecting belt 13. A clamping slot 12 is fixedly connected to the top of the moving plate 2 5. The clamping structure 7 includes a sleeve plate 701, a clamping plate 702 and a convex plate 703. A moving rod 704 is fixedly connected to the bottom of the convex plate 703, and a fixed disk 705 is fixedly connected to the bottom of the moving rod 704. A spring 706 is connected to the outer sleeve of the moving rod 704. The sleeve plate 701 is fixedly connected to one side of the moving plate 14, and the clamping plate 702 is slidably connected in the sleeve plate 701. The clamping plate 702 is clamped in the fixed column 15, and the convex plate 703 is fixedly connected to the top of the clamping plate 702. The moving rod 704 is slidably connected in the sleeve plate 701, and the fixed disk 705 is connected to the outer surface of the sleeve plate 701 through a spring 706.

[0034] By setting the sleeve 701, a pulling force is applied to the card plate 702 through the convex plate 703. When the card plate 702 and the moving rod 704 slide in the sleeve 701, the spring 706 is driven to deform through the fixed plate 705, so that the sleeve 701 plays a certain guiding role in the movement of the card plate 702 and the moving rod 704, thereby preventing the card plate 702 and the moving rod 704 from falling off during movement.

[0035] The working principle and use process of the present invention:

[0036] Before using the device, the moving plate 1 4 and the moving plate 3 6 can be slid with the L-shaped groove 10 on the left side of the detection bed 3, and the convex plate 703 is used to apply tension to the card plate 702. When the card plate 702 and the moving rod 704 slide in the sleeve plate 701, the spring 706 is deformed through the fixed plate 705. When the moving plate 1 4 fits with the auxiliary sleeve 1 805, the fixed column 15 below will be inserted with it. When the convex plate 703 is released, the card plate 702 will be reset by the spring 706. The reset card plate 702 will be clamped with the fixed column 15, so that the moving plate 1 4 and the auxiliary sleeve 1 805 can be fixed, and the moving plate 2 5 is connected with the auxiliary sleeve 2 806 in the same way;

[0037] When the patient's testing part needs to be fixed, the motor 803 drives the threaded rod 2 802 to rotate. Since the threaded rod 2 802 is connected to the threaded rod 1 801 through the anti-slip belt 804, the threaded rod 1 801 and the threaded rod 2 802 will rotate synchronously, and the moving plate 1 4 and the moving plate 2 5 will move evenly in the testing bed 3.

[0038] When the positions of the moving plate 1 4 and the moving plate 2 5 are adjusted, a pulling force is applied to the moving plate 3 6 to the left, and the connecting plate 902 slides in the concave plate 901. The arc block 903 contacts the ratchet 905 when moving, and the ratchet 905 rotates around the rotating rod 904. The ratchet 905 drives the coil spring 906 to deform when rotating. When the moving plate 3 6 moves to the appropriate position, the ratchet 905 overlaps with the corresponding arc block 903 through the coil spring 906.

[0039] The telescopic connecting belt 13 is pulled by the slot block 14, and the telescopic connecting belt 13 slides in the slot block 14, and the slot block 14 is engaged with the corresponding slot 12 above the movable plate 2 5, so that the patient's detection part can be limited, and the detection bed 3 is moved into the image detector 1 by the horizontal mover 2, and the image detector 1 images the patient's detection part.

[0040] 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.
