Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary device technology, specifically an adjustment mechanism based on the transport bed of a radiology CT machine. Background Technology

[0002] CT scanners utilize the penetrating power of X-rays to obtain information about the human body's interior. When X-rays pass through the body, different tissues absorb them to varying degrees. For example, high-density tissues like bone absorb more X-rays, while soft tissues absorb relatively less. These different absorption patterns create signals of varying intensities on the detector.

[0003] CT scanners typically consist of a detection end and a transport end. The transport end is generally adjustable in both vertical and horizontal directions. Vertical adjustment allows the patient to lie flat on the transport bed, while horizontal adjustment allows the patient's head to enter the detection end for testing. However, the vertical and horizontal adjustments are separate, making them somewhat cumbersome. Therefore, this invention designs an adjustment mechanism based on the transport bed of a radiology CT scanner to solve the above problems. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides an adjustment mechanism based on the transport bed of a radiology CT machine.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] An adjustment mechanism based on the transport bed of a radiology CT scanner includes a base plate, a curved guide ring, several transmission balls, a transport bed plate, and a limiting guide component;

[0007] The bottom end of the curved guide ring is a vertical part, and the top end of the curved guide ring is an inclined part;

[0008] The bottom end of the curved guide ring is fixed to the base plate, and several transmission balls are located inside the curved guide ring. The transmission ball at the bottom is driven by a lifting actuator.

[0009] The bottom of the conveyor bed is fixed with a through shaft by two mounting plates. The curved guide ring has a through inclined hole that bends in its own direction. The through shaft passes through the through inclined hole and is located above the topmost transmission ball.

[0010] The limiting guide is horizontally slidably connected to the base plate, and the conveying bed plate can be lifted and lowered on the limiting guide;

[0011] When adjusting the transport bed, the lifting actuator drives the bottom transmission ball to rise. Through the transmission of several transmission balls, the direction of force is changed, so that the top transmission ball first moves upward along the vertical part of the curved guide ring, and then moves obliquely along the inclined part of the curved guide ring. This causes the transport bed to move with the top transmission ball, transporting one end of the transport bed to the detection end of the CT machine.

[0012] Preferably, the angle between the vertical portion and the inclined portion of the curved guide ring is between 95 degrees and 115 degrees.

[0013] Preferably, a reinforcing rod is fixedly installed at the top end of the curved guide ring, and the bottom end of the reinforcing rod is fixed to the base plate.

[0014] Preferably, the upper surface of the base plate is also provided with a T-shaped groove, the bottom of the limiting guide is fixed with a T-shaped slider located inside the T-shaped groove and slidingly engaged with the T-shaped groove, the top of the limiting guide is provided with a vertical guide hole, and the bottom of the conveying bed plate is fixed with a vertical guide rod inserted into the vertical guide hole.

[0015] Preferably, the base plate has a receiving cavity in the middle, and the lifting actuator is located inside the receiving cavity. The lifting actuator includes a pair of fixed supports, and a reverse threaded rod is rotatably connected between the pair of fixed supports. Two movable sliders are rotatably sleeved on the outer side of the reverse threaded rod. The lifting actuator also includes a lifting disk located inside a curved guide ring. Two side plates are fixed on the lifting disk, and the end of the side plate away from the lifting disk is movably connected to the top of the movable slider through a connecting diagonal rod.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention uses a lifting actuator to drive the bottommost transmission ball upwards. Through the transmission of several intermediate transmission balls, the topmost transmission ball first moves vertically upwards and then diagonally, causing the transport bed to move with the topmost transmission ball, thus sending the transport bed into the CT scanner's detection end. Compared to existing designs, this invention can achieve both vertical and horizontal movement of the transport bed by providing only a vertical driving force, thereby pushing one end of the transport bed to the CT scanner's detection end for easier detection.

[0024] Example

[0025] like Figure 2 As shown, an adjustment mechanism based on the transport bed of a radiology CT machine includes a base plate 1, a curved guide ring 3, several transmission balls 4, a transport bed plate 5, and a limiting guide 6.

[0026] The bottom end of the curved guide ring 3 is a vertical part, and the top end of the curved guide ring 3 is an inclined part;

[0027] The bottom end of the curved guide ring 3 is fixed on the base plate 1, and a number of the transmission balls 4 are located inside the curved guide ring 3. The transmission ball 4 at the bottom is driven by the lifting actuator 2.

[0028] The bottom of the conveyor bed 5 is fixed with a through shaft by two mounting plates. The curved guide ring 3 has a through inclined hole that bends in its own direction. The through shaft passes through the through inclined hole and is located above the topmost transmission ball 4.

[0029] The limiting guide 6 is horizontally slidably connected to the base plate 1, and the conveying bed plate 5 is vertically and vertically mounted on the limiting guide 6;

[0030] When adjusting the conveyor bed 5, the lifting actuator 2 drives the bottom transmission ball 4 to rise. Through the transmission of several transmission balls 4, the direction of force is changed, so that the top transmission ball 4 first moves upward along the vertical part of the curved guide ring 3, and then moves obliquely along the inclined part of the curved guide ring 3. The conveyor bed 5 moves with the top transmission ball 4, and one end of the conveyor bed 5 is conveyed to the detection end of the CT machine, after which the detection can be performed.

[0031] This invention enables the conveyor bed 5 to move in both vertical and horizontal directions by providing only a vertical driving force, thereby pushing one end of the conveyor bed 5 to the detection end of the CT machine for easy detection.

[0032] The angle between the vertical part and the inclined part of the curved guide ring 3 is between 95 degrees and 115 degrees;

[0033] This utility model sets the angle between the vertical part and the inclined part of the curved guide ring 3 between 95 degrees and 115 degrees. On the one hand, it can make the conveyor bed plate 5 have a horizontal component force, so that the conveyor bed plate 5 can be pushed in the horizontal direction. On the other hand, it can make the conveyor bed plate 5 have a vertical component force, so that the conveyor bed plate 5 can move downward under the action of gravity. The smaller the vertical component force, the better, as long as it can ensure that the conveyor bed plate 5 has enough gravity to descend.

[0034] The upper surface of the base plate 1 is also provided with a T-shaped slide groove 101. The bottom of the limiting guide member 6 is fixed with a T-shaped slider 602 located inside the T-shaped slide groove 101 and slidingly engaged with the T-shaped slide groove 101. The top of the limiting guide member 6 is provided with a vertical guide hole 601. The bottom of the conveying bed plate 5 is fixed with a vertical guide rod 501 inserted into the vertical guide hole 601.

[0035] This utility model, through the combined use of T-shaped groove 101 and T-shaped slider 602, can ensure that the conveyor bed plate 5 moves in the horizontal direction, and through the combined use of vertical guide rod 501 and vertical guide hole 601, can ensure that the conveyor bed plate 5 moves in the vertical direction, thereby achieving the stable stability of the conveyor bed plate 5.

[0036] A reinforcing rod 301 is fixedly installed at the top of the curved guide ring 3, and the bottom end of the reinforcing rod 301 is fixed on the base plate 1;

[0037] By incorporating a reinforcing rod 301, this invention enables the bending guide ring 3 to be more stable and achieve better operational performance.

[0038] like Figure 3As shown, the base plate 1 has a receiving cavity 102 in the middle. The lifting actuator 2 is located inside the receiving cavity 102. The lifting actuator 2 includes a pair of fixed supports 201. A reverse threaded rod 202 rotates between the pair of fixed supports 201. Two movable sliders 203 are rotatably sleeved on the outer side of the reverse threaded rod 202. The lifting actuator 2 also includes a lifting disc 204 located inside the curved guide ring 3. Two side plates 205 are fixed on the lifting disc 204. The end of the side plate 205 away from the lifting disc 204 is movably connected to the top of the movable slider 203 through a connecting diagonal rod 206.

[0039] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
