[0029] The lower surface of the fixed bed board is also provided with a receiving cavity which matches with the movable bed board. When the movable bed board is in a horizontal state, a part of the movable bed board is in the receiving cavity. The opening of the receiving cavity has an arc surface to avoid wear on the surface of the movable bed board.

[0030] In an embodiment provided by the present invention, an operating screw is also provided at the opening of the accommodating cavity, and the operating screw is installed on the movable bed board by a threaded connection. By rotating the operating screw, the operating screw can generate a feeding movement, and the end of the operating screw has a supporting boss, and when the operating screw generates a feeding movement, the supporting boss supports the lower surface of the movable bed board.

[0049] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0050] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0051] like Figure 1 As shown, in an embodiment of the present invention, a multi-position adjustable scanning examination bed includes a fixed bed board 100 and a movable bed board 200, wherein the fixed bed board 100 is supported on a fixed mounting bracket assembly; the movable bed board 200 is supported and mounted on a movable slide 302 through an angle adjustment device 400, and the position of the movable slide 302 is adjustably arranged on the bracket assembly.

[0052] In the specific implementation of the multi-position adjustable scanning examination bed provided by the present invention, first, the position of the movable slide 302 relative to the bracket assembly is adjusted according to the patient's height and body shape, that is, the position of the movable bed board 200 relative to the fixed bed board 100 is adjusted, and then the inclination angle of the movable bed board 200 is adjusted based on the angle adjustment device 400, so that the inclination angle of the movable bed board 200 meets the patient's usage requirements, wherein the movable bed board 200 adjusted to the required angle is used to provide more effective support for the patient's waist and back.

[0053] Specifically, in an embodiment of the present invention, in order to achieve position adjustment of the movable slide 302 relative to the bracket assembly, the movable slide 302 is supported and slidably sleeved on the guide beam 300, and the inner cavity of the guide beam 300 is provided with an adjusting screw for supporting rotation, and a supporting slide is provided on the adjusting screw, and the supporting slide is installed on the adjusting screw by a threaded connection.

[0054] Furthermore, in an embodiment of the present invention, a forward and reverse servo motor 301 for driving the adjusting screw to rotate is installed at one end of the guide beam 300, and the movable slide 302 is fixedly connected to the supporting slide, so that when the adjusting screw is driven by the forward and reverse servo motor 301 to adjust the position of the supporting slide, the movable slide 302 is also synchronously pushed to move on the guide beam 300; wherein, the guide beam 300 support is fixedly installed on the bracket assembly, therefore, adjusting the position of the movable slide 302 relative to the guide beam 300 means realizing the position adjustment of the movable slide 302 relative to the bracket assembly.

[0055] Furthermore, in order to keep the movable bed board 200 in a stable and reliable state after adjusting the angle, Figure 5 , Figure 6 and Figure 8 As shown, in an embodiment of the present invention, an implementation method of the angle adjustment device 400 is provided. In the implementation method provided by the present invention, the angle adjustment device 400 includes a movable rack 404, and the movable rack 404 is sleeved on the support screw 408 by a threaded connection. The movable rack 404 is supported and slidably arranged on the fixed support plate 401, and the fixed support plate 401 is fixedly mounted on the movable slide 302. Therefore, by rotating the support screw 408, the position of the movable rack 404 relative to the support screw 408 can be adjusted.

[0056] Furthermore, in the embodiment of the present invention, the angle adjustment device 400 further includes:

[0057] The half-toothed turntable 403 meshing with the movable rack 404 is supported and rotatably arranged on the supporting side plate 402, and the supporting side plate 402 is supported and fixedly installed on the fixed support plate 401. When the movable rack 404 is displaced, the half-toothed turntable 403 can be driven to rotate a moving angle.

[0058] Furthermore, in the embodiment of the present invention, a plurality of limiting through holes 4031 are distributed in a circular array on the half-toothed rotating disk 403 .

[0059] Preferably, in an embodiment of the present invention, the movable bed board 200 is supported and fixedly mounted on a support rod body 700, and the support rod body 700 is coaxially supported and fixedly connected with the half-tooth turntable 403. Therefore, when the half-tooth turntable 403 is rotated, the support rod body 700 is also synchronously rotated by a certain angle. Since the movable bed board 200 is fixedly mounted on the support rod body 700, the inclination angle of the movable bed board 200 can be adjusted by causing the movable rack 404 to produce a certain displacement.

[0060] Furthermore, in the embodiment of the present invention, the angle adjustment device 400 further includes:

[0061] The operating mechanism 600 is connected to one end of the support screw 408 . The operating mechanism 600 can be operated to rotate the support screw 408 , and then the position of the moving rack 404 can be adjusted according to the rotation direction of the support screw 408 .

[0062] For further information, please refer to Figure 5 , Figure 6 and Figure 8 In the embodiment of the present invention, the angle adjustment device 400 further includes:

[0063] The locking assembly includes a support rod 4071 that is supported and slidably arranged on the fixed support plate 401, and a push-pull pin 407 is fixedly installed on the support rod 4071. The end of the support rod 4071 is fixedly connected to the operating ring 4072, and the operating ring 4072 is coaxially rotatably sleeved on the operating mechanism 600, that is, when the operating mechanism 600 rotates, it will not drive the operating ring 4072 to rotate.

[0064] Preferably, in an embodiment of the present invention, the locking assembly also includes a limit slider 406, and the limit slider 406 is elastically supported on the supporting side plate 402 through a connecting spring 405. A limit pin 4061 that is compatible with the limit through hole 4031 is fixedly installed on the limit slider 406. When the limit pin 4061 is inserted into the corresponding limit through hole 4031, it will have the effect of limiting the continued rotation of the half-tooth turntable 403.

[0065] Further, such as Figure 8 As shown, in the embodiment of the present invention, the limit slider 406 is provided with a slope 4062, and the push-pull pin 407 slides against the slope 4062. When the push-pull pin 407 is pushed to move, the push-pull pin 407 against the slope 4062 will push the limit slider 406 to be displaced, so that the limit pin 4061 is disengaged from the limit through hole 4031. Conversely, when the push-pull pin 407 is not moved by external force, under the elastic support of the connecting spring 405, the limit slider 406 will be pushed to move until the limit pin 4061 is against the limit through hole 4031, thereby locking the half-tooth turntable 403. At this time, the half-tooth turntable 403 will not rotate.

[0066] Please continue reading Figure 5-Figure 8 In the embodiment of the present invention, the operating mechanism 600 includes a fixed cylinder 601 fixedly mounted on a fixed support plate 401, a limit gear 604 is slidably and rotatably arranged inside the fixed cylinder 601, a square rod 602 is coaxially and fixedly mounted on one side of the limit gear 604, an operating round rod 607 is coaxially and fixedly mounted on the other side of the limit gear 604, and an operating handle 605 is fixedly mounted on the other end of the operating round rod 607.

[0067] Furthermore, in the embodiment of the present invention, a fixed gear ring 606 cooperating with the limiting gear 604 is fixedly installed in the fixed cylinder 601 .

[0068] Furthermore, in the embodiment of the present invention, the operating mechanism 600 further includes a support spring 603 , one end of the support spring 603 is fixedly connected to the support screw rod 408 , and the other end of the support spring 603 is fixedly connected to the limit gear 604 .

[0069] In the embodiment of the present invention, the square rod 602 slides coaxially along the axial direction and extends into the square hole on the support screw 408, so that when the square rod 602 is displaced relative to the support screw 408, it does not affect the rotation of the square rod 602 and drives the support screw 408 to rotate.

[0070] In the present invention, the operating handle 605 is operated to drive the operating round rod 607 to rotate, thereby driving the square rod 602 to rotate, thereby driving the supporting screw rod 408 to rotate.

[0071] Furthermore, in a specific embodiment of the present invention, the operating handle 605 is first manually pushed to move so that the limit gear 604 is disengaged from the fixed gear ring 606. At this time, the limit gear 604 can rotate. Conversely, when the operating handle 605 is not manually pushed to move, under the elastic support of the support spring 603, the limit gear 604 will engage with the fixed gear ring 606. Since the fixed gear ring 606 is fixedly connected to the fixed cylinder 601, the rotation of the limit gear 604 can be limited at this time, that is, the rotation of the support screw 408 can be limited.

[0072] Preferably, in an embodiment of the present invention, the operating ring 4072 is coaxially rotatably sleeved on the operating handle 605. When the operating handle 605 moves, the operating ring 4072 will move synchronously. It can be seen that when the operating ring 4072 is sleeved on the operating handle 605, the operating ring 4072 can only rotate on the operating handle 605 without generating relative movement.

[0073] From the above description of the specific structure of the angle adjustment device 400, it can be seen that the specific implementation process of the angle adjustment device 400 provided by the present invention is as follows:

[0074] The pressed operating handle 605 moves, so that the limiting gear 604 is disengaged from the fixed gear ring 606. At the same time, the moving operating handle 605 will synchronously drive the operating ring 4072 to move, so as to push the push-pull pin 407 to move. The moving push-pull pin 407 abuts against the inclined surface 4062 to push the limiting slider 406 to move. At this time, the limiting pin 4061 will also be disengaged from the limiting through hole 4031.

[0075] Further, the square rod 602 is driven to rotate by the operating handle 605. Since the square rod 602 coaxially slides along the axial direction and extends into the square hole on the support screw 408, the support screw 408 is driven to rotate. The rotating support screw 408 pushes the movable rack 404 to move, thereby driving the semi-toothed turntable 403 to rotate at a certain angle, which will synchronously drive the support rod body 700 and the movable bed board 200 installed on the support rod body 700 to rotate the moving angle, thereby adjusting the inclination angle of the movable bed board 200.

[0076] On the contrary, when there is no need to adjust the angle of the movable bed board 200, under the elastic support of the support spring 603, the limit gear 604 is against the fixed gear ring 606, and the rotation of the support screw 408 is locked and restricted; at the same time, the limit pin 4061 of the locking assembly will be against the limit through hole 4031, which has the effect of limiting the rotation of the half-tooth turntable 403. Therefore, the angle adjustment device 400 provided by the present invention can lock the half-tooth turntable 403 and the support screw 408 at the same time, so that the movable bed board 200 maintains a stable and reliable state, so that the multi-position adjustment scanning examination bed of the present invention is very stable and reliable in the process of supporting the patient after sitting up.

[0077] Please continue reading Figure 1-Figure 2 In an embodiment of the present invention, the support assembly comprises:

[0078] A first support leg 101, wherein the first support leg 101 is fixedly mounted on the bottom of the fixed bed board 100;

[0079] The second support leg 103 is supported and fixedly connected to the first support leg 101 through the first crossbeam 102 ; the second support leg 103 also supports and fixes a second crossbeam 1031 , and the second crossbeam 1031 is provided with a protective buffer mechanism 500 .

[0080] Preferably, in an embodiment of the present invention, the protective buffer mechanism 500 is located below the movable bed board 200, and the protective buffer mechanism 500 includes a protective support rod 501, and the end support of the protective support rod 501 is slidably arranged in a vertical guide rail 1032, and the vertical guide rail 1032 is opened on the second support leg 103; the protective support rod 501 is supported and arranged on the second cross beam 1031 by multiple groups of buffer springs 502.

[0081] The multi-position adjustable scanning examination bed provided by the present invention provides buffer support to the movable bed plate 200 when the movable bed plate 200 is in a horizontal state through the provided protection buffer mechanism 500 .

[0082] Furthermore, in the embodiment of the present invention, a headrest 201 is also provided on the movable bed board 200 to improve the comfort of the patient when lying on the multi-position adjustable scanning examination bed.

[0083] Please continue reading Figure 2-Figure 4 In the embodiment of the present invention, the lower surface of the fixed bed board 100 is further provided with a receiving cavity 104 which cooperates with the movable bed board 200 . When the movable bed board 200 is in a horizontal state, a part of the movable bed board 200 is in the receiving cavity 104 .

[0084] Furthermore, the opening of the accommodating cavity 104 has an arc surface 105 to prevent the straight edges from causing wear to the surface of the movable bed board 200.

[0085] Furthermore, in the embodiment of the present invention, an operating screw 107 is also provided at the opening of the accommodating cavity 104. The operating screw 107 is installed on the movable bed board 200 by a threaded connection. By rotating the operating screw 107, the operating screw 107 can generate a feeding movement.

[0086] Furthermore, in an embodiment of the present invention, the end of the operating screw rod 107 has a supporting boss 106. When the operating screw rod 107 generates a feeding movement, the supporting boss 106 supports the lower surface of the movable bed board 200. When the position of the movable bed board 200 relative to the fixed bed board 100 is adjusted, a part of the movable bed board 200 will be against the opening of the accommodating cavity 104. At this time, the supporting boss 106 is used to support the movable bed board 200.

[0087] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and the embodiments. It can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily realized.
