Description

Technical Field

[0001] This utility model belongs to the field of mechanical design and manufacturing technology, and in particular relates to a high-precision transmission plug-in structure for a radiation source. Background Technology

[0002] According to a published patent (CN213878586U), a plug-in / plug-out structure includes a slot with an opening and a limiting mechanism disposed on the slot. By providing a limiting mechanism on the slot, when the plug-in / plug-out body is in the slot, the limiting mechanism can prevent the plug-in / plug-out body from sliding out of the slot. This limiting mechanism can prevent the plug-in / plug-out body from suddenly falling and causing damage to the body or injuring the operator during the loosening of the fixing screw. However, it still has the following shortcomings:

[0003] The above-mentioned equipment achieves the effect of preventing materials from falling during insertion and removal. However, in scientific research experiments, the testing of different radiation energies requires frequent changes in the type of radiation source. If the insertion and removal process is not performed, the radiation source may be in a semi-exposed state for a long time, which may lead to the unshielded release of radiation, thereby causing harm to workers and the environment. Therefore, we provide a high-precision transmission insertion and removal structure for radiation sources. Utility Model Content

[0004] The purpose of this invention is to provide a high-precision transmission insertion and removal structure for a radioactive source. Through the insertion and removal mechanism and the lifting mechanism, the problem of preventing materials from falling during insertion and removal is solved after the above-mentioned equipment is completed. However, in scientific research experiments, the type of radioactive source needs to be changed frequently for testing different radiation energies. If the insertion and removal process is not performed, the radioactive source may be in a semi-exposed state for a long time, which may lead to the unshielded release of radiation, thereby causing harm to workers and the environment.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a high-precision transmission plug-in structure for a radiation source, including a motherboard, a slide rail fixedly connected to the top outer wall of the motherboard, and a plug-in mechanism provided on the outer wall of the motherboard.

[0007] The insertion and removal mechanism includes a motor plate, the outer wall of which is fixedly connected to the outer wall of the main plate. A controller is fixedly connected to the outer wall of the motor plate near the slide rail, and a motor is fixedly connected to the outer wall of the motor plate away from the slide rail. The bottom output shaft of the motor is fixedly connected to a rotating shaft via a coupling. A bevel gear is fixedly connected to the outer wall of the rotating shaft away from the motor. A threaded rod is rotatably connected to the inner wall of the main plate. A second bevel gear is fixedly connected to the outer wall of the threaded rod near the bevel gear. The outer wall of the second bevel gear meshes with the outer wall of the bevel gear. A threaded barrel is threadedly connected to the outer wall of the threaded rod. A sliding frame is fixedly connected to the outer wall of the threaded barrel near the slide rail.

[0008] Furthermore, the outer wall of the sliding frame is slidably connected to the inner wall of the slide rail, and the inner wall of the sliding frame is threaded with several bolts, the outer wall of the bolts being threaded with a limit plate.

[0009] Furthermore, the inner wall of the limiting plate is provided with several anti-slip grooves, the inner wall of the limiting plate is slidably connected to a transmission pipe, the outer wall of the transmission pipe is slidably connected to the outer wall of the sliding frame, and the outer wall of the main board is provided with a lifting mechanism.

[0010] Furthermore, the lifting mechanism includes several telescopic rods, the outer walls of the several telescopic rods are fixedly connected to the outer wall of the main board, and a base plate is fixedly connected to the outer wall of the end of the telescopic rod away from the main board.

[0011] Furthermore, a second motor plate is fixedly connected to the outer wall of the base plate near the main board, a second controller is fixedly connected to the outer wall of the second motor plate near the motor plate, and a self-locking motor is fixedly connected to the outer wall of the second motor plate away from the controller.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model uses a sliding frame to place the transmission tube with the interface end on the surface of the sliding frame. Then, a limiting plate is placed on the surface of the transmission tube. The movement of the sliding frame allows the interface end of the transmission tube to align with the interface end of the radiation source. The motor is then started by the controller to complete the separation process between the interface end of the transmission tube and the interface end of the radiation source. This achieves both the ability to insert and limit the transmission tube.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-6 As shown, this utility model is a high-precision transmission plug-in structure for a radiation source, including a motherboard 1, a slide rail 101 fixedly connected to the top outer wall of the motherboard 1, and a plug-in mechanism 2 provided on the outer wall of the motherboard 1.

[0030] The insertion / removal mechanism 2 includes a motor plate 201, the outer wall of which is fixedly connected to the outer wall of the main board 1. The main board 1 fixes the position of the slide rail 101, preventing the slide rail 101 from shifting during use and causing the device to malfunction. A controller 202 is fixedly connected to the outer wall of the motor plate 201 near the slide rail 101, and a motor 203 is fixedly connected to the outer wall of the motor plate 201 away from the slide rail 101. The bottom output shaft of the motor 203 is fixedly connected to a rotating shaft 204 via a coupling. A bevel gear 205 is fixedly connected to the outer wall of the rotating shaft 204 away from the motor 203. The motor plate 201 fixes the position of the motor 203, preventing the motor 203 from shifting during operation and causing damage. A threaded rod 206 is rotatably connected to the inner wall of the main board 1. A second bevel gear 207 is fixedly connected to the outer wall of one end near the bevel gear 205. The outer wall of the second bevel gear 207 meshes with the outer wall of the bevel gear 205. A threaded barrel 208 is threadedly connected to the outer wall of the threaded rod 206. The rotation of the bevel gear 205 drives the second bevel gear 207 to rotate, preventing the second bevel gear 207 from affecting the rotation of the bevel gear 205 and causing the device to jam. A sliding frame 209 is fixedly connected to the outer wall of the threaded barrel 208 near the slide rail 101. The outer wall of the sliding frame 209 is slidably connected to the inner wall of the slide rail 101. Several bolts 210 are threadedly connected to the inner wall of the sliding frame 209. A limit plate 211 is threadedly connected to the outer wall of the bolts 210. The threaded barrel 208 moves by the rotation of the threaded rod 206, avoiding the problem that the threaded barrel 208 cannot move and the device cannot complete the insertion and removal process.

[0031] The inner wall of the limiting plate 211 is provided with several anti-slip grooves 212. A transmission pipe 213 is slidably connected to the inner wall of the limiting plate 211. The outer wall of the transmission pipe 213 is slidably connected to the outer wall of the sliding frame 209. A lifting mechanism 3 is provided on the outer wall of the main board 1. The anti-slip grooves 212 stabilize the position of the transmission pipe 213 and prevent the transmission pipe 213 from falling off during processing, which would affect the normal use of the device. The lifting mechanism 3 includes several telescopic rods 301. The outer walls of the telescopic rods 301 are fixedly connected to the outer wall of the main board 1. A base plate 3 is fixedly connected to the outer wall of the end of the telescopic rod 301 away from the main board 1. 02. The position of the telescopic rod 301 is fixed by the base plate 302 to prevent the telescopic rod 301 from tilting during use and causing the device to jam. A motor plate 2 303 is fixedly connected to the outer wall of the end of the base plate 302 closest to the main plate 1. A controller 2 304 is fixedly connected to the outer wall of the end of the motor plate 2 303 closest to the motor plate 201. A self-locking motor 305 is fixedly connected to the outer wall of the end of the motor plate 2 303 away from the controller 2 304. The position of the self-locking motor 305 is fixed by the motor plate 2 303 to prevent the self-locking motor 305 from changing position during operation and causing damage.

[0032] The bottom output shaft of the self-locking motor 305 is fixedly connected to a rotating shaft 306 via a coupling. The outer wall of the rotating shaft 306 is rotatably connected to the inner wall of the base plate 302. A gear 307 is fixedly connected to the outer wall of the end of the rotating shaft 306 away from the self-locking motor 305. The base plate 302 ensures stable rotation of the rotating shaft 306, preventing tilting during rotation and ensuring proper operation of the device. A rotating shaft 308 is rotatably connected to the inner wall of the base plate 302 near the rotating shaft 306. A gear 309 is fixedly connected to the outer wall of the end of the rotating shaft 308 near the gear 307. The outer wall of the rotating shaft 306 meshes with the outer wall of the gear 307. The rotation of the gear 307 drives the second gear 309 to rotate, preventing the second gear 309 from affecting the rotation of the gear 307 and causing jamming. The outer walls of the rotating shaft 306 and the rotating shaft 308 are both fixedly connected to the rotating plate 310. The outer wall of the rotating plate 310 away from the motor plate 303 is rotatably connected to the second rotating plate 311. The outer wall of the second rotating plate 311 is rotatably connected to the inner wall of the main plate 1. The rotation of the rotating plate 310 drives the second rotating plate 311 to rotate stably, avoiding the problem that the second rotating plate 311 cannot rotate, which would prevent the device from completing the lifting and lowering process.

[0033] One specific application of this embodiment is:

[0034] When the operator needs to use the equipment, firstly, the self-locking motor 305 is started via controller 2 304. The self-locking motor 305 causes rotating shaft 2 306 to rotate. Rotating shaft 2 306 drives gear 307 to rotate, which in turn drives gear 2 309 to rotate. Gear 2 309 drives rotating shaft 308 to rotate. The rotation of rotating shaft 2 306 and rotating shaft 308 causes rotating plates 310 at both ends to rotate in opposite directions. Rotating plates 310 drive rotating plate 2 311 to rotate, which in turn drives rotating plate 2 311 to rotate. 11 drives the mainboard 1 to move stably via multiple telescopic rods 301. The rotation of rotating plate 310 and rotating plate 311 is used to raise and lower the mainboard 1. Then, the transmission pipe 213 with the interface end is placed at the contact position on the surface of the sliding frame 209. Next, the limiting plate 211 is placed at the contact position with the surface of the transmission pipe 213. The bolt 210 is rotated to make it pass through the limiting plate 211 and rotate into the sliding frame 209. The bolt 210 is used to fix the limiting plate 211 on the sliding frame 209. At this time, the limiting plate 211 and the transmission pipe 213 are in mutual abutment. In the controlled state, the anti-slip groove 212 prevents the transmission tube 213 from shifting during insertion and removal. Then, the controller 202 starts the motor 203, which causes the rotating shaft 204 to rotate. The rotating shaft 204 drives the bevel gear 205 to rotate, which in turn drives the second bevel gear 207 to rotate. The second bevel gear 207 drives the threaded rod 206 to rotate, which in turn moves the threaded barrel 208. The threaded barrel 208 then moves the sliding frame 209 within the slide rail 101, and the sliding frame 209 drives the bolt 210 and... The limiting plate 211 and the transmission tube 213 move, and the sliding frame 209 moves to connect the interface end of the transmission tube 213 with the interface end of the radiation source. The sealing ring of the transmission tube 213 makes the two ports sealed. After the two interfaces are connected, the controller 202 shuts down the motor 203 again. When the transmission tube 213 needs to be separated from the radiation source, the controller 202 starts the motor 203 again. Then the motor 203 drives the above parts to operate in reverse, thus completing the separation process between the transmission tube 213 and the interface end of the radiation source.
