Specifically, referring to fig. 1, fig. 2 and fig. 3, the cover 110 includes a cover main body 111, a first elastic member 114, a cover core and an actuating mechanism.

The cover body 111 is slidably disposed on the upper end of the inner cylinder 100, and the cover body 111 can move linearly between a first initial position and a first compressed position. Specifically, the cover main body 111 is disposed outside the upper end of the inner tube 100.

The cover main body 111 is connected with the inner cylinder 100 through the first elastic member 114, so that the cover main body 111 can be in a natural state by the first elastic member 114 at a first initial position, and the first elastic member 114 is in a compressed state when the cover main body 111 is at a first compressed position; that is, the purpose of the first elastic element 114 is to drive the cover main body 111 to return to the first initial position without external force after compression, and the first elastic element 114 is an elastic body such as rubber, in this embodiment, the first elastic element 114 is a spring.

Optionally, in order to ensure stability of vertical operation and prevent the first elastic member 114 from deviating, the upper end of the inner cylinder 100 is provided with a first protrusion 101, an inner wall of the first protrusion 101 is flush with an inner wall of the inner cylinder 100, a step-shaped annular gap 103 is formed between an outer wall of the first protrusion 101 and the upper end surface of the inner cylinder 100, the cover main body 111 has a ring portion 113 annularly disposed on the first protrusion 101, under the above setting condition, the first elastic member 114 is slidably sleeved on the first protrusion 101, and two ends of the first elastic member 114 are respectively connected with the ring portion 113 and the upper end surface of the inner cylinder 100.

The cap body 111 has an opening for inserting and removing the medicine bottle into and from the inner cylinder 100, and a cap core is located in the inner cylinder 100 and rotatably connected to the upper end of the inner cylinder 100 via a rotating shaft 118. Wherein the rotating shaft 118 extends in a radial or tangential direction of the inner barrel 100.

Specifically, with continuing reference to fig. 1, 2 and 3, the cover core includes a strip-shaped connecting portion 115 and a table-shaped core portion 116 connected to each other, and an end of the connecting portion 115 away from the core portion 116 is connected to the rotating shaft 118; the cap body 111 has an internal cavity that mates with the core 116, the upper end of the cavity being provided with an opening, the spherical-table-shaped core 116 facilitating subsequent rotation into and out of the cavity.

The strip-shaped connecting portion 115 has a certain elasticity, for example, made of stainless steel, so as to ensure that the core portion 116 is smoothly separated from the inner cavity during the pressing process.

Referring to fig. 4, when the rotating shaft 118 extends in a tangential direction of the inner cylinder 100, only one end of the core 116 is connected to the rotating shaft 118 through the connecting portion 115, and the cap core moves around the rotating shaft 118 as shown by an arrow along with the rotation of the rotating shaft 118.

Referring to fig. 2 and 3, in the present embodiment, the rotating shaft 118 extends along the radial direction of the inner cylinder 100, and in order to ensure the smooth movement of the core 116, one end of the core 116 is connected to the rotating shaft 118 through a connecting portion 115, and the other end is hinged to the inner cylinder 100 through another strip-shaped connecting portion 115.

Regardless of the manner in which the rotating shaft 118 is disposed, the connecting portion 115 has a circular arc shape. Especially, under the condition that the rotating shaft 118 adopted in the embodiment extends along the radial direction of the inner barrel 100, the arc-shaped arrangement can effectively avoid influencing the connection part 115 after opening to influence the access passage of the medicine bottle, and meanwhile, the deformation space is large, and it should be noted that, when the rotating shaft extending along the radial direction of the inner barrel 100 coincides with the diameter of the outer spherical surface of the core part 116, the diameter of the outer spherical surface of the core part 116 should be smaller than the diameter of the inner barrel 100.

In this embodiment, the distance between the bottom surface of the core 116 and the axis of rotation 118 is greater than the radius of the vial. The influence on the access of the medicine bottle by the connecting part 115 after opening is effectively avoided.

It should be noted that the crank shaft may extend along the radial direction or the tangential direction of the inner cylinder 100, and here, the crank shaft may extend along the radial direction of the inner cylinder 100, that is, the crank shaft is coaxially connected with the rotating shaft 118.

The second component is a connecting rod 125, two ends of the connecting rod 125 are respectively hinged with the cover main body 111 and the crank pin 122 of the crank wheel 121, the crank pin 122 is eccentrically arranged on the crank wheel 121, and the crank pin 122 and the crank shaft are respectively positioned on two opposite side surfaces of the crank wheel 121; as shown in fig. 4, when the cover main body 111 is at the first initial position, the crank pin 122 is located at the upper end of the crank wheel 121, and when the cover main body 111 moves vertically from the first initial position to the first compressed position, the crank wheel 121 is driven to rotate by the rotation of the crank pin 122, so that the cover core is rotationally switched from the closed position to the open position.

With the above-described actuating mechanism 120, the connecting rod 125 is disposed outside the cover body 111, and the crank wheel 121 is also disposed outside the inner cylinder 100, and it should be noted that, in this condition, the upper end of the inner cylinder 100 should still extend outside the outer cylinder 130 after being located at the second compression position, so that the crank wheel 121 is always located outside the outer cylinder 130 and is not damaged during the pressing-down process.

Referring to fig. 2 and fig. 3, in the present embodiment, the first component is a gear 127; the second component is a rack 129 that mates with the gear 127, the rack 129 being fixedly mounted to the lid body 111.

Referring to fig. 3, in the present embodiment, since the rotating shaft 118 extends along the radial direction of the inner cylinder 100, the gear 127 is coaxially connected with the rotating shaft 118, and the surface of the tooth is in the tangential direction of the inner cylinder 100 and is in meshed connection with the gear 127.

When the rotating shaft 118 extends along the tangential direction of the inner cylinder 100, as in the scheme shown in fig. 4, the number of the gears 127 is two, the two gears 127 are meshed with each other, the surface where the teeth of the rack 129 are located is located on one side of the rack 129 close to the outer wall of the inner cylinder 100, the rack 129 moving downwards drives the first gear 127 meshed with the rack 129 to rotate anticlockwise, the first gear 127 rotating anticlockwise drives the second gear 127 to rotate clockwise, and the rotating shaft 118 is coaxially connected with the second gear 127.

The outer cylinder 130 is also composed of a stainless steel outer shell and a radiation shielding cylindrical inner core, wherein the lower end of the outer cylinder 130 can be sealed by a radiation shielding material, for example, a plate made of a radiation shielding material is used to seal the lower end of the outer cylinder 130, and the plate is connected with the lower end of the outer cylinder 130 in a detachable manner, for example, so as to facilitate subsequent overhaul of the components installed in the outer cylinder 130.

Specifically, the inner barrel 100 has a second initial position and a second compressed position; the installation space is provided therein with a second elastic member 131 connected to the inner cylinder 100, so that the second elastic member 131 in a natural state can support the upper end of the inner cylinder 100 to extend out of the outer cylinder 130 and be located at a second initial position. The closed installation space effectively prevents radioactive contamination.

Meanwhile, in the practical application process, by selecting the selection of the medicine bottle corresponding to the size of the accommodating device, when the cap main body 111 is pressed to enable the cap main body 111 to be located at the first compression position and the inner barrel 100 to be located at the second compression position, the medicine bottle located in the inner barrel 100 can extend out of the opening, so that the medicine bottle can be taken out or put into the inner barrel 100 under the condition that the stroke of a subsequent mechanical arm is not changed.

The second elastic member 131 is provided to drive the inner cylinder 100 to automatically return to the second initial position without external force after being compressed, wherein the second elastic member 131 is an elastic body such as rubber, and in this embodiment, the second elastic member 131 is a spring.

Further, the elastic modulus of the first elastic element 114 is smaller than that of the second elastic element 131, so that the first elastic element 114 is deformed before the second elastic element 131 under the action of the robot arm.

The activity meter 140 is located in the installation space and at the lower end of the inner cartridge 100. As shown in FIG. 1, the lower end of the vial that enters the inner cartridge 100 through the opening can be placed directly on the activity meter 140.
