Quickly assemblable and disassemblable target part connecting structure for BNCT and method therefor

An assemblable and disassemblable target part connecting structure for a boron neutron capture therapy, comprising:

• a target section, a pipeline section, and at least one locking device configured to connect the target section and the pipeline section, wherein the at least one locking device comprises:
• a lock body provided with a locking pin configured for elastically extending and contracting along a radial direction;
• a lock rod provided with a lock groove for accommodating an extension of the locking pin along the radial direction, wherein a sliding block is slidably connected in the lock groove along an axial direction, two ends of the sliding block are each provided with a first guide face and a second guide face, and the first guide face and the second guide face converge at a maximum outer diameter of the sliding block;
• and
• a driving mechanism configured to drive the lock rod to telescopically move along the axial direction relative to the lock body and provide a continuous pulling force in a locked state,
• wherein the driving mechanism and the lock body are fixedly disposed on the target section and the pipeline section respectively, a first end of the lock rod is fixedly connected with the driving mechanism, and a second end of the lock rod is a free end;
• a side of the lock groove adjacent to the free end of the lock rod is provided with an accommodating groove adapted to the first guide face;
• and the free end of the lock rod is provided with a second guide portion.
