In the implementation of the present application, please refer to fig. 2, and fig. 2 is a schematic structural diagram of another imaging device provided in the embodiment of the present application. The bulb moving assembly 200 in the imaging device 000 may include: a first runner 201 and a second runner 202. The first moving member 201 is connected to a first mounting position 001a of the rotating frame 001, and the second moving member 202 is connected to the first moving member 201 and the bulb 100, respectively. The first runner 100 is configured to: causing the bulb 100 to move in a first direction. The second runner 202 is configured to: causing the bulb 100 to move in a second direction.

Wherein the reference coordinate system of the imaging device 000 has: three coordinate axes of X-axis, Y-axis and Z-axis. The first direction and the second direction are respectively: any two directions of six directions, i.e., an X-axis direction, a Y-axis direction, a Z-axis direction, a rotation direction around the X-axis, a rotation direction around the Y-axis, and a rotation direction around the Z-axis.

Thus, the ball tube moving assembly 200 can drive the ball tube 100 to move in three directions by the first moving member 201, the second moving member 202 and the third moving member 203, so that the imaging device 000 can meet the requirements of imaging effects of different imaging devices.

In the embodiment of the present application, there are multiple possible implementation manners for the connection between the first moving part 201 and the first mounting position 001a, and the first moving part 201, the second moving part 202, and the third moving part 203, and the embodiment of the present application is schematically illustrated by taking the following two possible implementation manners as examples:

in a first possible implementation manner, when the first moving member 201 moves along any one of the X-axis direction, the Y-axis direction and the Z-axis direction (i.e. the first direction), the first moving member 201 and the first mounting position 001a are linearly and slidably connected. And/or when the second moving part 202 moves along any one direction (namely, the second direction) of the X-axis direction, the Y-axis direction and the Z-axis direction, which is different from the first direction, the second moving part 202 is linearly and slidably connected with the first moving part 201. And/or when the third moving part 203 moves along any one direction (namely, the third direction) of the X-axis direction, the Y-axis direction and the Z-axis direction, which is different from the first direction and the second direction, the third moving part 203 and the second moving part 202 are in linear sliding connection.

In a second possible implementation manner, when the first moving member 201 moves in any one of the rotation direction around the X axis, the rotation direction around the Y axis, and the rotation direction around the Z axis (i.e., the first direction), the first moving member 201 is rotatably connected to the first mounting position 001 a. And/or, when the second moving part 202 moves along any direction (namely, a second direction) different from the first direction in the rotating direction around the X axis, the rotating direction around the Y axis and the rotating direction around the Z axis, the second moving part 202 is rotatably connected with the first moving part 201. And/or, when the third moving member 203 moves along a direction (i.e. a third direction) different from the first direction and the second direction among the rotating direction around the X axis, the rotating direction around the Y axis, and the rotating direction around the Z axis, the third moving member 203 and the second moving member 202 are rotationally connected.

In the embodiment of the present application, as shown in fig. 3, fig. 3 is a schematic structural diagram of a bulb moving assembly in the imaging device shown in fig. 2. The bulb imaging device 200 may further include: a first slide rail 204. The first moving member 201 is linearly connected with the first installation position 001a in a sliding manner through a first sliding rail 204. That is, the first moving member 201 can drive the bulb 100 to move on the first sliding rail 204. The extending direction of the first sliding rail 204 is the same as the first direction. So, through setting up this first slide rail 204, can guarantee that first moving member 201 only drives bulb 100 and remove in the first direction, improved the precision of adjusting the position of bulb 100.

Illustratively, as shown in fig. 3, the first runner 201 may include: a first support plate 201a, a first moving structure (not shown), and a handle 201 b. The first support plate 201a is slidably connected to the first slide rail 204, and the first support plate 201a is connected to the bulb 100. The first moving structure may be a lead screw nut structure. The nut is fixedly connected with the first supporting plate 201a and can be sleeved on the screw rod; one end of the screw is connected to the handle 201b, and the extending direction of the screw is the same as the first direction. When the position of bulb 100 needs to be adjusted, handle 201b is rotated, and this handle 201b can drive the lead screw and rotate for the nut moves on the extending direction of lead screw, and then can drive first backup pad 201a and slide on first slide rail 204, makes bulb 100 move on first direction, thereby realizes adjusting the position of bulb 100.

Optionally, one end of the lead screw connected to the handle 201b is provided with a locking ring, and the locking ring can lock the lead screw after the bulb 100 moves to a preset position, so as to fix the position of the bulb 100.

It should be noted that, the embodiment of the present application is schematically illustrated by taking the example that the handle 201b manually drives the screw rod to rotate, and in other possible implementations, the screw rod may be driven to rotate by an electric drive or a hydraulic drive.

It should be further noted that, in the embodiment of the present application, the first moving structure is schematically illustrated as a screw nut structure, and in other possible implementation manners, the first moving structure may also adopt a structure that can implement linear movement, such as a V-shaped groove or optical axis guide.

Optionally, the bulb moving assembly 200 may further include: a second slide rail (not shown). The second moving part 202 is linearly connected with the first moving part 201 in a sliding manner through a second sliding rail, that is, the second moving part 202 can drive the bulb 100 to move on the second sliding rail. The extending direction of the second slide rail is the same as the second direction. So, through setting up this second slide rail, can guarantee that second moving member 202 only drives bulb 100 and removes in the second direction, improved the precision of adjusting the position of bulb 100.

By way of example, the second runner 202 may include: a second support plate (not shown), a second moving structure (not shown), and a handle (not shown). The principle that the second moving part 202 drives the bulb 100 to move on the second slide rail can refer to the related content that the first moving part 201 drives the bulb 100 to move on the first slide rail, and this embodiment of the present application is not described herein again.

In this application, the bulb moving assembly 200 in the imaging device 000 may further include: a rotor (not shown). The third moving part 203 is rotatably connected with the second moving part 202 through a rotating part. Thus, through the rotating member, the third moving member 203 can drive the bulb 100 to rotate around the third direction by different angles, so that the imaging device 000 can achieve different imaging effects.

Alternatively, the rotatable member may be a bearing assembly (not shown) that is rotatable in a third direction.

It should be noted that in other alternative implementations, the rotating member may also rotate in other rotating manners.

In this application, as shown in fig. 4, fig. 4 is a top view of the bulb moving device shown in fig. 3, the third moving member 203 has an arc-shaped groove 203a, and the bulb moving device 200 may further include: and a locating pin 205. The positioning pin 205 may pass through the arc-shaped slot 203a and then be connected to the second moving member 202. Thus, when the bulb 100 needs to be rotated, the fixed connection between the positioning pin 205 and the second moving part 202 can be cancelled, so that the third moving part 203 can drive the bulb 100 to rotate; after the ball tube 100 is rotated to a preset angle by the third moving member 203, the positioning pin 205 may be fixedly connected with the second moving member 202 to fix the ball tube 100.

In the embodiment of the present application, referring to fig. 2, the detector moving assembly 400 in the imaging apparatus 000 may include: a fourth runner 401 and a fifth runner 402. The fourth moving member 401 is connected to the second mounting position 001b of the rotating frame 001, and the fifth moving member 402 is connected to the fourth moving member 401 and the detector 300, respectively. The fourth runner 401 is configured to: the probe 300 is moved in the fourth direction, and the fifth moving member 402 is configured to move the probe 300 in the fifth direction. Wherein, the fourth direction and the fifth direction are respectively: any two directions of six directions, i.e., an X-axis direction, a Y-axis direction, a Z-axis direction, a rotation direction around the X-axis, a rotation direction around the Y-axis, and a rotation direction around the Z-axis. In this way, the probe moving assembly 400 can drive the probe 300 to move in two directions by the fourth moving member 401 and the fifth moving member 402, so that the imaging device 000 can meet the requirements of imaging effects of different imaging apparatuses.

In this application, referring to fig. 2, the detector moving assembly 400 in the imaging apparatus 000 may further include: a sixth moving member 403. The sixth moving part 403 is connected to the fifth moving part 402 and the detector 300, respectively, and the sixth moving part 403 is configured to: bringing the detector 300 in a sixth direction. Among the six directions, the sixth direction is a direction different from the fourth direction and the fifth direction, such as the X-axis direction, the Y-axis direction, the Z-axis direction, the rotational direction around the X-axis, the rotational direction around the Y-axis, and the rotational direction around the Z-axis. Thus, the detector moving assembly 400 can drive the detector 300 to move in three directions through the fourth moving member 401, the fifth moving member 402 and the sixth moving member 403, so that the imaging device 000 can meet the requirements of imaging effects of different imaging devices.

In the embodiment of the present application, there are multiple possible implementation manners for the connection between the fourth moving part 401 and the second mounting position 001b, and between the fourth moving part 401, the fifth moving part 402, and the sixth moving part 403, and the embodiment of the present application is schematically illustrated by taking the following two possible implementation manners as examples:

in a first possible implementation manner, when the fourth moving member 401 moves along any one of the X-axis direction, the Y-axis direction and the Z-axis direction (i.e. the fourth direction), the fourth moving member 401 is linearly slidably connected with the second mounting position 001 b. And/or when the fifth moving part 402 moves along any direction (namely, the fifth direction) of the X-axis direction, the Y-axis direction and the Z-axis direction, which is different from the fourth direction, the fifth moving part 402 is in linear sliding connection with the fourth moving part 401. And/or when the sixth moving member 403 moves in any direction (i.e. sixth direction) of the X-axis direction, the Y-axis direction and the Z-axis direction, which is different from the fourth direction and the fifth direction, the sixth moving member 403 and the fifth moving member 402 are linearly and slidably connected.

In a second possible implementation manner, when the fourth moving member 401 moves in any one of the rotation direction around the X axis, the rotation direction around the Y axis, and the rotation direction around the Z axis (i.e., the fourth direction), the fourth moving member 401 is rotatably connected to the second mounting position 001 b. And/or when the fifth moving member 402 moves in any direction (i.e. the fifth direction) different from the fourth direction among the rotating direction around the X axis, the rotating direction around the Y axis and the rotating direction around the Z axis, the fifth moving member 402 is rotatably connected with the fourth moving member 401. And/or when the sixth moving member 403 moves in a direction (i.e., a sixth direction) different from the fourth direction and the fifth direction among the rotation direction around the X axis, the rotation direction around the Y axis, and the rotation direction around the Z axis, the sixth moving member 403 is rotatably connected with the fifth moving member 402.

In the present application, as shown in fig. 5 and 6, fig. 5 is a schematic structural view of a detector moving assembly in the imaging apparatus shown in fig. 2, and fig. 6 is a top view of the detector moving assembly shown in fig. 5. The probe movement assembly 400 may further include: a third slide rail 404. The fourth moving part 401 is linearly slidably connected with the second mounting position 001b through a third slide rail 404. That is, the fourth moving part 401 can drive the detector 300 to move on the third sliding rail 404. The extending direction of the third sliding rail 404 is the same as the fourth direction. Thus, by arranging the third slide rail 404, it can be ensured that the fourth moving member 401 only drives the detector 300 to move in the fourth direction, and the accuracy of adjusting the position of the detector 300 is improved.

For example, as shown in fig. 5 and 6, the fourth moving part 401 may include: a fourth support plate 401a, a fourth moving structure (not shown), and a handle 401 b. The principle that the fourth moving element 401 drives the detector 300 to move on the third sliding rail 404 can refer to the related content that the first moving element 201 drives the bulb tube 100 to move on the first sliding rail 204, and this embodiment of the present application is not described herein again.

Optionally, referring to fig. 6, the detector moving assembly 400 may further include: a fourth slide rail 405. The fifth moving part 402 and the fourth moving part 401 are linearly connected by a fourth sliding rail 405 in a sliding manner, that is, the fifth moving part 402 can drive the detector 300 to move on the fourth sliding rail 405. The fourth slide rail 405 extends in the same direction as the fifth direction. So, through setting up this fourth slide rail 405, can guarantee that fifth moving member 402 only drives detector 300 and removes in the fifth direction, improved the precision of adjusting the position of detector 300.

For example, as shown in fig. 5 and 6, the fifth moving part 402 may include: a fifth support plate 402a, a fifth moving structure (not shown), and a handle 402 b. The principle that the fifth moving element 402 drives the detector 300 to move on the fourth sliding rail 405 may refer to the related content that the first moving element 201 drives the bulb 100 to move on the first sliding rail 203, and this embodiment of the present application is not described herein again.

Optionally, the detector moving assembly 400 may further include: a fifth slide rail (not shown). The sixth moving part 403 and the fifth moving part 402 are connected in a linear sliding manner through a fifth slide rail. That is, the sixth moving part 403 can drive the detector 300 to move on the fifth sliding rail. The extending direction of the fifth slide rail is the same as the sixth direction. So, through setting up this fifth slide rail, can guarantee that sixth moving member 403 only drives detector 300 and upwards moves in the sixth, improved the precision of adjusting the position of detector 300.

For example, the sixth moving part 403 may include: a sixth support plate (not shown), a sixth moving structure (not shown), and a handle (not shown). The principle that the sixth moving element 403 drives the detector 300 to move on the fifth sliding rail can refer to the related content that the first moving element 201 drives the bulb tube 100 to move on the first sliding rail 204, and this embodiment of the present application is not described herein again.

In the embodiment of the present application, please refer to fig. 6 and 7, the imaging apparatus 000 may further include: the first position indicating assembly 500 and/or the second position indicating assembly 600.

As such, with the first and second

500 and 600, the positions of the bulb 100 and the probe 300 in the imaging device 000 may be indicated, so as to adjust the positions between the bulb 100 and the probe 300 and the isocenter of the imaging apparatus or adjust the relative positions between the bulb 100 and the probe 300 as needed.

In this application, there are many possible implementations of the structure of the first position indicating assembly 500, and the embodiment of this application is schematically illustrated by taking the following three possible implementations as examples:

The third position indicator 602 is adapted to cooperate with the third scale 601 to indicate the position of the detector 300 in the fourth direction. The third scale 601 is connected to the second mounting position 001b of the rotating frame 001, and the extending direction of the third scale 601 is the same as the fourth direction. Thus, the third scale 601 cooperates with the third position indicator 602 to measure the distance the detector 300 moves in the fourth direction.

In a second possible implementation manner, when the detector moving assembly 400 includes the fifth moving member 402, the second position indicating assembly 600 may further include: a fourth scale (not shown) and a fourth position indicator (not shown). The fourth position pointer is adapted to cooperate with the fourth scale to indicate the position of the detector 300 in the fifth direction. The fourth scale is connected to the fourth moving member 401, and the extending direction of the fourth scale is the same as the fifth direction. Thus, the fourth scale, in cooperation with the fourth position indicator, can measure the distance that the probe 300 moves in the fifth direction.

In a third possible implementation manner, when the probe moving assembly 400 includes the sixth moving member 403, the second position indicating assembly 600 may further include: a fifth scale (not shown) and a fifth position pointer (not shown). The fifth position indicator is adapted to cooperate with the fifth scale to indicate the position of the detector 300 in the sixth orientation. The fifth scale is connected to the fifth moving member 402, and the extending direction of the fifth scale is the same as the sixth direction. Thus, the fifth scale, in cooperation with the fifth position index, can measure the distance the probe 300 moves in the sixth direction.
