DETAILED DESCRIPTION

[0019] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0020] like Figure 1 As shown, a push rod mechanism 100 in one embodiment of the present invention is arranged at the end of a medicine box storage slideway in a medicine box storage device to prevent the medicine box from sliding off the slideway. The push rod mechanism 100 includes a driving component 10 and a buffer component 20. The buffer component 20 is connected to the driving component 10 and is driven by the driving component 10 to approach or move away from the end of the slideway. The buffer component 20 includes a flexible stopper 21 for receiving the medicine box.

[0021] In actual operation, there is a certain distance between the block 21 and the slideway. When a medicine box needs to be stored in a certain slideway, the driving assembly 10 drives the block 21 to move to the end of the corresponding medicine box slideway, and then starts to dispense medicine. The flexible block 21 can provide buffering and blocking for the falling medicine box, avoiding the direct collision of the medicine box with the end baffle of the slideway, causing the medicine box to slide, and even when the medicine box contains a glass container for storing solution, the direct collision causes the container to break.

[0022] In one embodiment, the stopper 21 is made of foam, and can certainly be made of other flexible materials such as rubber, which is not limited in this embodiment.

[0023] Preferably, Figure 2 As shown, the stopper 21 includes a main body 211 and an extension 212 protruding from the main body 211. The extension 212 is arranged on one end of the main body 211 close to the slideway and extends in a direction perpendicular to the extension of the slideway. Therefore, the extension 212 expands the contact area between the stopper 21 and the medicine box, thereby improving stability. Figure 2In the illustrated embodiment, the extension portion 212 extends from the main body portion 211 toward one side, and may also extend toward other directions, which is not limited in this embodiment.

[0024] like Figure 2 As shown, in addition to the block 21, the buffer assembly 20 also includes a mounting frame 22 and a plurality of damping rods 23. The mounting frame 22 is connected to the drive assembly 10, the damping rod 23 is fixed on the mounting frame 22, and the block 21 is fixed on the damping rod 23. When the medicine box to be dropped is heavy, resulting in the block 21 being unable to completely absorb the kinetic energy of the medicine box when it falls, the damping rod 23 intervenes to offset the remaining kinetic energy of the medicine box when it falls, and prevents the heavier medicine box from directly hitting the mounting frame 22. Secondly, the damping rod 23 slowly resets after compression, which can reduce the rebound force of the medicine box. And the damping rod 23 can cooperate with the drive assembly 10, and can more accurately control the ejection distance of the block 21, thereby adapting to the installation deviation of the slide, ensuring that the block 21 receives the medicine box and preventing the medicine box from falling.

[0025] In one embodiment, the buffer assembly 20 further includes a mounting plate 24 connected to the damping rod 23, and the stopper 21 is fixed on the mounting plate 24. The mounting plate 24 is a plate body with a groove on the surface, and the shape of the groove is the same as the bottom shape of the stopper 21 to ensure the shape of the stopper 21 and prevent the stopper 21 from being twisted and deformed.

[0026] Preferably, a guide structure is further provided between the mounting plate 24 and the mounting frame 22, including a guide column 25 fixed to the bottom of the mounting plate 24, and a guide hole (not shown) provided on the mounting frame 22. The guide column 25 is inserted into the guide hole to further limit the moving direction of the mounting plate 24 relative to the mounting frame 22 and reduce the load on the damping rod 23. That is, when the mounting plate 24 has a tendency to move in other directions, the forces in other directions are borne by the guide column 25 to prevent the damping rod 23 from failing or being damaged.

[0027] exist Figure 2 In the embodiment, a guide seat 26 is fixed on the mounting frame 22, and a guide hole is formed on the guide seat 26. The guide seat 26 extends the length of the guide hole, reduces the force per unit area of ​​the surface of the guide column 25, thereby preventing the guide column 25 from bending or even breaking, and improving the overall stability.

[0028] In one embodiment, the driving assembly 10 includes a guide rail 11, a base plate 12, a slider 13 and a power source 14, wherein the base plate 12 is fixed to one end of the guide rail 11, the slider 13 is supported on the guide rail 11, the mounting frame 22 is fixed to the slider 13, and the power source 14 is fixed to the base plate 12, which connects and drives the slider 13 to move on the guide rail 11, thereby driving the block 21 to move into or away from the slideway. For example, the power source 14 can be a cylinder, and the slider 13 is fixed to the output shaft of the cylinder, and is directly driven by the cylinder to move on the guide rail 11.

[0029] Or preferably, a base plate 12 is fixed at both ends of the guide rail 11, and the drive assembly 10 also includes a lead screw 15 with one end supported on one side of the base plate 12, and the slider 13 is threadedly matched with the lead screw 15. The power source 14 is a motor fixed on the other base plate 12, which is connected to and drives the lead screw 15 to rotate. Under the action of the thread, the lead screw 15 rotates to drive the slider 13 to move. Compared with the cylinder drive, the motor drives the slider 13 through the lead screw drive to make the movement of the slider 13 more delicate and more accurate. After the block 21 moves and stays at the target position (in the slideway), when the slider 13 tends to retreat due to the collision of the medicine box, the force transmitted to the motor is smaller, which can protect the power source 14.

[0030] Preferably, the power source 14 is disposed on the bottom plate 12 away from one end of the medicine box storage slideway to avoid interfering with the movement of the stopper 21 on the other side.

[0031] like Figure 3 As shown, this embodiment also provides a blocking mechanism 200 in a medicine box storage device for preventing a medicine box from sliding off, and in addition to the above-mentioned push rod mechanism 100, it also includes a displacement mechanism 30 for driving the push rod mechanism 100 to move between different medicine box slideways. Since the number of drug injection ports is generally less than the total number of slideways, and not all drug injection ports are used at the same time, it is not necessary to set too many push rod mechanisms 100 in the medicine box storage device to avoid waste of resources.

[0032] exist Figure 3 In the embodiment, the displacement mechanism 30 includes two first guide rails 31 arranged horizontally, and a second guide rail 32 arranged vertically. A displacement slider 33 is arranged at each end of the second guide rail 32, and the second guide rail 32 is supported on the first guide rail 31 through the displacement slider 33. A horizontal power source 34 is arranged at the end of the first guide rail 31, which is used to drive the second guide rail 32 to move in the horizontal direction. A base 35 is arranged on the second guide rail 32, which is driven by a vertical power source 36 to move in the vertical direction. The first guide rail 31 and the second guide rail 32 constitute a two-dimensional displacement network, so that the push rod mechanism 100 can switch between different slideways.

[0033] Preferably, a horizontally arranged transmission belt 37 is also arranged on the base 35. When a medicine box slides down the slideway, the medicine box can fall onto the transmission belt 37, and the transmission belt 37 collects and sorts the medicine box and then takes it out for re-administration. A medicine receiving plate 38 is also arranged above the transmission belt 37. The medicine receiving plate 38 is inclined upward and is used to receive the medicine box that has slipped down and make it slide smoothly onto the transmission belt 37.

[0034] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
