[0032] The movable frame 220 is slidably connected to the base 210. The first driving member 230 can drive the movable frame 220 to slide on the base 210, so that the movable frame 220 can be raised and lowered.

[0036] It is understandable that, referring to Figure 2 and Figure 4 The first driving member 230 includes a spur rack 231, a first gear 232, and a first motor 233. The spur rack 231 is fixedly connected to the base 210, and the first gear 232 is rotatably connected to the movable frame 220.

The spur rack 231 is fixedly connected to the base 210, and the first gear 232 is rotatably connected to the movable frame 220. The first gear 232 is meshed with the spur rack 231. The first motor 233 drives the first gear 232 to rotate, so that the first gear 232 can move along the length of the spur rack 231, thereby driving the movable frame 220 to move up and down, and conveniently adjusting the height of the detection mechanism 100.

[0037] A speed reducer is provided between the first gear 232 and the first motor 233 so that the first motor 233 can drive the first gear 232 to rotate smoothly.

[0038] It is understandable that, referring to Figure 1 and Figure 5 The second driving member 330 includes a second gear 331, a third gear 332, and a second motor 333. The second gear 331 and the third gear 332 are both rotatably connected to the movable frame 220. The rotating shaft 310 is fixedly connected to the second gear 331. The second gear 331 meshes with the third gear 332. The second motor 333 is used to drive the third gear 332 to rotate.

This achieves synchronous rotation of the rotating shaft 310 and the support frame 320, facilitates adjustment of the angle of the detection mechanism 100, and improves the flexibility of the X-ray imaging equipment.

[0039] A speed reducer is also provided between the third gear 332 and the second motor 333 so that the second motor 333 can drive the third gear 332 to rotate smoothly.

[0040] Specifically, refer to Figure 2 and Figure 6The rotating mechanism 300 also includes a controller, a limit rod 351, a baffle 352 and two first limit sensors 353. The limit rod 351 is fixedly connected to the second gear 331, the baffle 352 is rotatably connected to the movable frame 220, the movable frame 220 is connected to two springs 354, and the two springs 354 are symmetrically connected to the baffle 352. The two first limit sensors 353 are arranged at intervals on the movable frame 220. The limit rod 351 can drive the baffle 352 to rotate so that the baffle 352 triggers the first limit sensor 353. The first limit sensor 353 and the second motor 333 are both electrically connected to the controller. The limiting rod 351 is fixedly connected to the second gear 331 so that the second gear 331 can drive the limiting rod 351 to rotate, and the baffle 352 is rotatably connected to the movable frame 220. The two springs 354 are respectively arranged on both sides of the baffle 352, and one end of the spring 354 is connected to the movable frame 220, and the other end is connected to the baffle 352. The two springs 354 cooperate to stabilize the baffle 352 between the two first limit sensors 353.

[0041] When the second gear 331 drives the limit rod 351 to abut against the baffle 352, the baffle 352 can rotate to deform the two springs 354, and the baffle 352 can trigger one of the first limit sensors 353, so that the controller can control the second motor 333 to stop, so that the rotating shaft 310 can stop rotating to limit the rotation angle of the rotating shaft 310 and prevent the power cord and data cable from being cut; when the limit rod 351 is separated from the baffle 352, the two springs 354 are reset to pull the baffle 352 back between the two first limit sensors 353, so that the controller can control the second motor 333 to continue rotating, thereby improving the reliability of the X-ray imaging equipment.

[0042] It should be noted that the first limit sensor 353 can be a photoelectric sensor or an ultrasonic sensor, which will not be described in detail here.

[0043] Specifically, refer to Figure 6 and Figure 7The rotating mechanism 300 also includes a rotating wheel 361 and a second limit sensor 362.

The second limit sensor 362 is fixedly connected to the movable frame 220, and the second limit sensor 362 abuts against the side wall of the rotating wheel 361. When the second limit sensor 362 is stuck in the groove 363, the controller can drive the second motor 333 to stop, thereby controlling the rotation angle of the second gear 331 to limit the rotation angle of the rotating shaft 310, thereby avoiding the power cord and data cable from being cut, and improving the reliability of the X-ray imaging equipment.

[0044] It should be noted that both the first limit sensor 353 and the second limit sensor 362 can detect the rotation angle of the rotating shaft 310 , thereby improving the movement accuracy of the rotating shaft 310 and improving the reliability of the X-ray imaging equipment.

[0045] Among them, the second limit sensor 362 can be a travel switch, which will not be described in detail here.

[0046] Specifically, refer to Figure 2 、 Figure 3 and Figure 6 The movable frame 220 is fixedly connected to a rotating sleeve 371 and a positioning shaft 372. The rotating sleeve 371 is rotatably connected to the fourth gear 373. The third gear 332 is engaged with the fourth gear 373. The second driving member 330 also includes a potentiometer 374.

By setting the rotating shaft of the potentiometer 374 to be fixedly connected with the fourth gear 373, the potentiometer 374 can detect the rotation angle of the fourth gear 373, thereby detecting the rotation angle of the third gear 332, and conveniently detecting the position of the rotating shaft 310, thereby improving the reliability of the rotating mechanism 300.

[0047] Among them, the fourth gear 373 is sleeved on the rotating sleeve 371, so that the fourth gear 373 can be positioned in the axial and radial directions of the rotating sleeve 371, and the fourth gear 373 is rotationally connected to the rotating sleeve 371.

[0048] It is understandable that, referring to Figure 2 and Figure 5 The third driving member 340 includes a fifth gear 341, a sixth gear 342, and a third motor 343. The fifth gear 341 is fixedly connected to the rotating shaft 310, and the sixth gear 342 is rotatably connected to the support frame 320.

The sixth gear 342 is rotatably connected to the support frame 320. The third motor 343 drives the sixth gear 342 to rotate, so that the sixth gear 342 can rotate about the fifth gear 341, thereby driving the support frame 320 to rotate about the rotating shaft 310. This facilitates adjustment of the rotation angle of the support frame 320, facilitates detection by the detection mechanism 100, and improves the ease of use of the X-ray imaging device.

[0049] A speed reducer is also provided between the sixth gear 342 and the third motor 343 so that the third motor 343 can drive the sixth gear 342 to rotate smoothly.

[0050] It should be noted that the fifth gear 341 and the rotating shaft 310 are coaxially arranged, so that the fifth gear 341 and the sixth gear 342 cooperate to drive the support frame 320 to rotate smoothly on the rotating shaft 310 .
