Description

Technical Field

[0001] The invention relates to the technical field of pneumatic tube logistics transmission bottle transmission, in particular to a medical pneumatic tube logistics transmission bottle capping machine. Background Art

[0002] In the past, the transmission operation of medical equipment was mainly completed manually. However, due to the lack of knowledge of the transmission personnel, they were unable to understand many related issues. In addition, the medical staff did not communicate well in advance, which inevitably led to a series of problems, such as incorrect transmission destination, poor transmission timeliness and human misclassification, which could easily lead to serious medical safety issues.

[0003] Medical pneumatic logistics transmission system helps to optimize the workflow and improve the overall operation management level and operation efficiency of the hospital. Medical pneumatic logistics transmission bottles are mainly used to transport various medical items, including drugs, medical equipment, blood samples, documents, etc.

[0004] As for the current status of the industry, Figure 1 , 2 As shown in , 3, most medical pneumatic tube logistics bottles are standard double-screw cap type, that is, openings are provided at both ends of the bottle body, and the cap is buckled and sealed by means of a screw cap. Different from the most common threaded rotary bottle cap, the screw cap of the medical pneumatic tube logistics bottle is composed of a cover body and a plug column. The plug column is formed by the inner side wall of the cover body extending inward, eccentrically arranged, and close to the outer contour of the cover body. An insertion hole for the plug column to be inserted is provided on the end face of the bottle body. When the screw cap needs to be opened, the cover body is pushed sideways or rotated, and the cover body can perform a deflection movement around the insertion hole until the blockage of the bottle body opening is released. In order to further improve the transmission efficiency of the medical pneumatic logistics transmission system, the researchers initially envisioned that it is equipped with an automatic opening device. However, in the prior art, although a wide variety of opening mechanisms or opening devices can be retrieved, the applicable objects are mostly conventional threaded rotary bottle caps or flip-top bottle caps, which are difficult to apply to standard double-screw cap medical pneumatic tube logistics bottles. Therefore, technical personnel are urgently needed to solve the above problems. Summary of the invention

[0005] Therefore, in view of the above-mentioned existing problems and defects, the designers of the present invention collected relevant information, conducted multiple evaluations and considerations, and continued to experiment and modify after many years of R&D experience in this industry, which ultimately led to the emergence of the medical gas tube logistics bottle capping machine.

[0006] In order to solve the above technical problems, the present invention relates to a medical gas tube logistics bottle capping machine, comprising a frame, an upper capping mechanism, a lower capping mechanism, a guide assembly and a power unit. The upper capping mechanism and the lower capping mechanism are arranged opposite to each other in the up and down directions, and are both supported by the frame. The power unit uses the frame as an installation base. The movement directions of the upper capping mechanism and the lower capping mechanism are both guided by the guide assembly, and because they are simultaneously acted upon by the driving force from the power unit, they synchronously perform reverse displacement movements, so as to approach or move away from the medical gas tube logistics bottle.

[0007] As a further improvement of the technical solution disclosed in the present invention, the upper cover opening mechanism includes an upper cantilever platform, an upper mounting frame, an upper cover-pushing assembly and an upper driving unit. The lower cover opening mechanism includes a lower cantilever platform, a lower mounting frame, a lower cover-pushing assembly and a lower driving unit. The upper cantilever platform and the lower cantilever platform perform displacement movement in a directional manner under the coordinated action of the guide assembly and the power unit. The upper mounting frame and the lower mounting frame are fixed to the upper cantilever platform and the lower cantilever platform in a one-to-one and detachable manner, respectively. The upper cover-pushing assembly is arranged directly below the upper cantilever platform, and the lower cover-pushing assembly is arranged directly above the lower cantilever platform. The upper driving unit is used to drive the upper cover-pushing assembly to perform deflection movement, so that the rotary cap located at the upper port of the medical gas tube logistics transmission bottle can be opened / reset, and it uses the upper mounting frame as an assembly basis. The lower drive unit is used to drive the lower cover assembly to perform deflection movement, so that the rotary cover at the lower port of the medical gas tube transmission bottle can be opened / reset, and the lower mounting frame is used as an assembly basis.

[0008] As a further improvement of the technical solution disclosed in the present invention, the upper shift cover assembly includes an upper shift fork, a first upper conical top contact wheel and a second upper conical top contact wheel. The upper shift fork is directly subjected to the rotational torque from the upper drive unit to perform a deflection movement. The first upper conical top contact wheel and the second upper conical top contact wheel are respectively detachably mounted on the two ends of the upper shift fork. The lower shift cover assembly includes a lower shift fork, a first lower conical top contact wheel and a second lower conical top contact wheel. The lower shift fork is directly subjected to the rotational torque from the lower drive unit to perform a deflection movement. The first lower conical top contact wheel and the second lower conical top contact wheel are respectively detachably mounted on the two ends of the lower shift fork.

[0009] As a further improvement of the technical solution disclosed in the present invention, under the action of the friction force from the screw cap of the medical gas flow transfer bottle, the first upper conical top contact wheel, the second upper conical top contact wheel, the first lower conical top contact wheel and the second lower conical top contact wheel all freely perform circumferential rotational motion around their respective center axes.

[0010] As a further improvement of the technical solution disclosed in the present invention, the upper shift cover assembly includes an upper height limit plate. The lower shift cover assembly includes a lower height limit plate. The upper height limit plate is in contact with the bottom wall of the upper shift fork and is detachably fixed as a whole. The lower height limit plate is in contact with the top wall of the lower shift fork and is detachably fixed as a whole.

[0011] As a further improvement of the technical solution disclosed in the present invention, the upper height limit plate and the lower height limit plate are both made of elastomeric plastic. In the process of the first upper conical top contact wheel and the second upper conical top contact wheel approaching and pressing against the screw cap of the upper port of the medical gas tube flow transmission bottle, the upper height limit plate undergoes adaptive elastic deformation due to pressure. In the process of the first lower conical top contact wheel and the second lower conical top contact wheel approaching and pressing against the screw cap of the lower port of the medical gas tube flow transmission bottle, the lower height limit plate undergoes adaptive elastic deformation due to pressure.

[0012] As a further improvement of the technical solution disclosed in the present invention, the upper drive unit includes an upper single-axis steering gear and an upper gear transmission system. The upper single-axis steering gear is detachable to achieve fixation with the upper mounting frame, and the torque generated by the upper gear transmission system is transmitted to the upper cover assembly. The lower drive unit includes a lower single-axis steering gear and a lower gear transmission system. The lower single-axis steering gear is detachable to achieve fixation with the lower mounting frame, and the torque generated by the lower gear transmission system is transmitted to the lower cover assembly.

[0013] As a further improvement of the technical solution disclosed in the present invention, the upper cantilever platform is a combined assembly structure, which includes an upper platform body, a first upper cantilever beam and a second upper cantilever beam. The first upper cantilever beam and the second upper cantilever beam are respectively in contact with the left and right side walls of the upper platform body, and are fixed as a whole by means of an upper screw assembly. The lower cantilever platform is a combined assembly structure, which includes a lower platform body, a first lower cantilever beam and a second lower cantilever beam. The first lower cantilever beam and the second lower cantilever beam are respectively in contact with the left and right side walls of the lower platform body, and are fixed as a whole by means of a lower screw assembly.

[0014] As a further improvement of the technical solution disclosed in the present invention, the guide assembly includes a slide rail, an upper slider, a lower slider, an upper sliding assembly and a lower sliding assembly. The slide rail is detachably fixed to the right side wall of the frame. The upper slider and the lower slider used in pair with the slide rail respectively use the second upper cantilever beam and the second lower cantilever beam as the installation basis in a one-to-one correspondence. A sliding groove is provided on the other side of the frame. The upper sliding assembly and the lower sliding assembly, which are both inserted into the sliding groove and can slide in the up and down directions, respectively use the first upper cantilever beam and the first lower cantilever beam as the installation basis in a one-to-one correspondence.

[0015] As a further improvement of the technical solution disclosed in the present invention, the upper sliding assembly includes a first upper sliding block and a second upper sliding block. The first upper cantilever beam is composed of a first upper cantilever beam body as a first upper sliding block mounting base and an upper elastic lower extension of the second upper sliding block mounting base. The upper elastic lower extension is formed by continuing to extend downward from the bottom wall of the first upper cantilever beam body and undergoing at least two bends. The lower sliding assembly includes a first lower sliding block and a second lower sliding block. The first lower cantilever beam is composed of a first lower cantilever beam body as a first lower sliding block mounting base and a lower elastic lower extension of the second lower sliding block mounting base. The lower elastic lower extension is formed by continuing to extend downward from the bottom wall of the first lower cantilever beam body and undergoing at least two bends.

[0016] As a further improvement of the technical solution disclosed in the present invention, the power unit includes a load-bearing frame, a reduction motor, a transmission gear, a left rack and a right rack. The load-bearing frame is used to carry the reduction motor, and it is detachable to achieve fixation with the frame. The transmission gear performs circumferential rotation under the action of the torque from the reduction motor, and the left rack meshing with the transmission gear is able to drag the lower cover opening mechanism, and at the same time, the right rack meshing with the transmission gear is able to reversely drag the upper cover opening mechanism.

[0017] The working principle of the medical gas tube logistics bottle decapping machine disclosed in the present invention is roughly as follows: when it is necessary to perform an unloading operation on the medical gas tube logistics bottle, it is first shifted to the unloading station and its bottle body is clamped and fixed. Then, the power unit is started, and with the assistance of the guide component, the upper decapping mechanism and the lower decapping mechanism are simultaneously subjected to the driving force from the power unit to perform displacement movement until they respectively touch the upper port screw cap and the lower port screw cap of the medical gas tube logistics bottle. Subsequently, the upper decapping mechanism is actuated to apply a lateral rotational torque to the upper port screw cap, and the upper port screw cap is able to perform a circumferential rotational movement around its plug column until the blockage of the upper port of the medical gas tube logistics bottle is completely released. At the same time, the lower decapping mechanism is actuated to apply a lateral rotational torque to the lower port screw cap, and the lower port screw cap is able to perform a circumferential rotational movement around its plug column until the blockage of the lower port of the medical gas tube logistics bottle is completely released.

[0018] In practical applications, the medical gas tube logistics bottle capping machine disclosed in the present invention can achieve at least the following beneficial technical effects, specifically:

[0019] 1) The upper and lower ports of the medical gas tube logistics bottle are opened by means of the upper and lower opening mechanisms, respectively. The whole action process is fast and rapid, and various items required in medical work can fall from the medical gas tube logistics bottle automatically, and the whole process does not require manual intervention, which lays a good foundation for further improving the working rhythm of the pneumatic transmission line of the medical gas tube logistics bottle;

[0020] 2) The medical gas tube logistics bottle capping machine disclosed in the present invention has a very simple design structure, is easy to manufacture and implement, and requires low manufacturing costs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0042] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by the terms "left", "right", "up", "down", "front", "back", etc. are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0043] Figure 1 , 2 , 3 show a medical gas flow transmission bottle in the industry, which is a standard double screw-cap type, that is, there are openings at both ends of the bottle body, and both are covered and sealed by means of screw caps. The screw cap is composed of a cover body and a plug post. The plug post is formed by the inner side wall of the cover body continuing to extend inward, is eccentrically arranged, and is close to the outer contour of the cover body. An insertion hole for the plug post to be inserted is opened on the end face of the bottle body. When the screw cap needs to be opened, the cover body is pushed sideways or rotated, and the cover body can perform a deflection movement around the insertion hole until the blockage of the bottle body opening is released.

[0044] The present invention will be further described in detail below with reference to specific embodiments. Figure 4 , Figure 5 The three-dimensional schematic diagrams of the medical gas tube logistics bottle decapping machine disclosed in the present invention are shown in two different perspectives. It can be seen that it is mainly composed of a frame 1, an upper decapping mechanism 2, a lower decapping mechanism 3, a guide assembly 4 and a power unit 5. Among them, the upper decapping mechanism 2 and the lower decapping mechanism 3 are arranged opposite to each other along the up and down direction, and are both supported by the frame 1. The power unit 5 uses the frame 1 as an installation base. The movement directions of the upper decapping mechanism 2 and the lower decapping mechanism 3 are both guided by the guide assembly 4, and because they are simultaneously subjected to the driving force from the power unit 5, they synchronously perform reverse displacement movements to approach or move away from the medical gas tube logistics bottle. In practical applications, the upper and lower ports of the medical gas tube logistics bottle are opened by means of the upper opening mechanism 2 and the lower opening mechanism 3 respectively. The whole action process is fast and rapid, and various items required in medical work can fall from the medical gas tube logistics bottle automatically. The whole process does not require manual intervention, which lays a good foundation for further improving the working rhythm of the pneumatic transmission line of the medical gas tube logistics bottle.

[0045] It should also be noted that the medical gas tube logistics bottle capping machine disclosed in the present invention has a very simple design structure, is easy to manufacture and implement, and requires low manufacturing costs.

[0046] As is known, according to design common sense, the upper cover opening mechanism 2 and the lower cover opening mechanism 3 can adopt a variety of design structures to realize the toggle operation of the screw caps of the upper and lower ports of the medical gas tube transmission bottle. However, a design structure is recommended here, which is convenient for manufacturing and implementation, and the cover opening action is fast and reliable. Specifically, as follows: Figure 6 As shown in FIG. 1 , the upper cover opening mechanism 2 is mainly composed of an upper cantilever platform 21, an upper mounting frame 22, an upper cover opening assembly 23 and an upper driving unit 24. Fig.10 As shown in the figure, the lower cover opening mechanism 3 is mainly composed of a lower cantilever platform 31, a lower mounting frame 32, a lower cover opening assembly 33 and a lower driving unit 34. Figure 4 , 5, the upper cantilever platform 21 and the lower cantilever platform 31 perform displacement movement in a directional manner under the coordinated action of the guide assembly 4 and the power unit 5. The upper mounting frame 22 and the lower mounting frame 32 are fixed to the upper cantilever platform 21 and the lower cantilever platform 31 in a one-to-one and detachable manner. The upper cover assembly 23 is arranged directly below the upper cantilever platform 21, and the lower cover assembly 33 is arranged directly above the lower cantilever platform 31. The upper driving unit 24 is used to drive the upper cover assembly 23 to perform deflection movement, so that the rotary cap at the upper port of the medical gas tube logistics transmission bottle can be opened / reset, and it uses the upper mounting frame 22 as the assembly basis. The lower driving unit 34 is used to drive the lower cover assembly 33 to perform deflection movement, so that the rotary cap at the lower port of the medical gas tube logistics transmission bottle can be opened / reset, and it uses the lower mounting frame 32 as the assembly basis. As Fig. 9 As shown in the figure, the upper shift cover assembly 23 is mainly composed of an upper shift fork 231, a first upper conical top contact wheel 232 and a second upper conical top contact wheel 233. The upper shift fork 231 is directly subjected to the torque from the upper drive unit 24 to perform a deflection movement. The first upper conical top contact wheel 232 and the second upper conical top contact wheel 233 are detachably mounted on both ends of the upper shift fork 231. Fig.13As shown in the figure, the lower shift cover assembly 33 is mainly composed of a lower shift fork 331, a first lower conical top contact wheel 332 and a second lower conical top contact wheel 333. The lower shift fork 331 is directly subjected to the rotational torque from the lower driving part 34 to perform a deflection motion. The first lower conical top contact wheel 332 and the second lower conical top contact wheel 333 are detachably mounted on both ends of the lower shift fork 331. In this way, when it is necessary to perform an opening operation on the medical gas tube logistics transmission bottle, first, the upper cover-pushing assembly 23 and the lower cover-pushing assembly 33 are synchronously approached to the medical gas tube logistics transmission bottle due to the reverse driving force, until the first upper conical top contact wheel 232 and the second upper conical top contact wheel 233 are pressed on the outer contour surface of the upper port screw cap and the first lower conical top contact wheel 332 and the second lower conical top contact wheel 333 are pressed on the outer contour surface of the lower port screw cap, and then, the upper shift fork 231 performs a deflection movement due to the rotational torque from the upper driving part 24, and the rotation center line of the upper shift fork 231 coincides with the central axis of the plug column at the upper port of the medical gas tube logistics transmission bottle, and the first upper conical top contact wheel 232 and the second upper conical top contact wheel 233 are coordinated to move. At the same time, a rotational torque is applied to the upper port cap, and the upper port cap can perform a circumferential rotational movement around its plug column until the blockage of the upper port of the medical gas tube logistics bottle is completely released. At the same time, the lower fork 331 performs a deflection movement due to the rotational torque from the lower driving part 34, and the rotation center line of the lower fork 331 coincides with the central axis of the plug column of the lower port of the medical gas tube logistics bottle. The first lower conical top contact wheel 332 and the second lower conical top contact wheel 333 cooperate to apply a rotational torque to the lower port cap, and the lower port cap can perform a circumferential rotational movement around its plug column until the blockage of the lower port of the medical gas tube logistics bottle is completely released, and various items required in medical work can fall from the medical gas tube logistics bottle by themselves.

[0047] In the early initial design, the first upper conical top contact wheel 232 and the second upper conical top contact wheel 233 are both fixed non-rotatably at the two ends of the upper fork 231, and the first lower conical top contact wheel 332 and the second lower conical top contact wheel 333 are both fixed non-rotatably at the two ends of the lower fork 331. However, in actual application, the following problems are found: taking the upper port screw cap of a medical gas flow transmission bottle as an example, when it is necessary to perform an opening operation on it, the upper port screw cap performs a circumferential rotational motion around its plug column due to the action of the rotational torque. In the process, the first upper conical top contact wheel 232 and the second upper conical top contact wheel 233 slide and rub along the outer contour of the upper port screw cap. The outer contour of the upper port screw cap is very likely to be scratched and worn due to the action of the sliding friction. In view of this, as a further optimization of the above technical solution, Fig. 9 , 13As shown in the figure, the first upper conical top contact wheel 232, the second upper conical top contact wheel 233, the first lower conical top contact wheel 332 and the second lower conical top contact wheel 333 are all independently equipped with rolling bearings. Under the friction force from the screw cap of the medical gas tube logistics bottle, the first upper conical top contact wheel 232, the second upper conical top contact wheel 233, the first lower conical top contact wheel 332 and the second lower conical top contact wheel 333 are all freely circumferentially rotating around their respective central axes. In this way, on the one hand, the relative friction value of the outer contour of the screw cap during the uncapping process can be effectively reduced, thereby preventing the occurrence of accelerated damage due to long-term wear; on the other hand, it is conducive to self-correcting the relative position and tilting posture of the medical gas tube logistics bottle, ensuring that the upper cover assembly 23 and the lower cover assembly 33 can correctly apply rotational torque to the upper and lower ports of the medical gas tube logistics bottle.

[0048] Depend on Fig. 9 , 13It can also be clearly seen that the upper cover assembly 23 is further provided with an upper height limit plate 234. The lower cover assembly 33 is further provided with a lower height limit plate 334. The upper height limit plate 234 is in contact with the bottom wall of the upper shift fork 231 and is detachably fixed as a whole. The lower height limit plate 334 is in contact with the top wall of the lower shift fork 331 and is detachably fixed as a whole. Both the upper height limit plate 234 and the lower height limit plate 334 are made of elastomeric plastic. In this way, in the process of the first upper conical top contact wheel 232 and the second upper conical top contact wheel 233 approaching and pressing against the screw cap of the upper port of the medical gas tube flow transmission bottle, the upper height limit plate 234 undergoes adaptive elastic deformation due to pressure. In the process of the first lower conical top contact wheel 332 and the second lower conical top contact wheel 333 approaching and pressing against the screw cap of the lower port of the medical gas tube flow transmission bottle, the lower height limit plate 334 undergoes adaptive elastic deformation due to the pressure. In this way, on the one hand, because the upper height limit plate 234 and the lower height limit plate 334 are elastic bodies and are pressed against the screw caps of the upper and lower ports of the medical gas tube flow transmission bottle respectively, in the process of opening the cap, in addition to the first upper conical top contact wheel 232, the second upper conical top 233, the first lower conical top contact wheel 332 and the second lower conical top contact wheel 333, which play a major role, a part of the rotational torque can also be applied to the screw caps of the upper and lower ports through the upper height limit plate 234 and the lower height limit plate 334 respectively, to ensure that the opening operation can be smoothly completed. Implementation and development; on the other hand, in view of the limiting effect of the upper limit height plate 234, the outer contour of the upper port screw cover can be effectively prevented from being damaged and deformed due to the excessive extrusion pressure from the first upper conical top contact wheel 232 and the second upper conical top 233. Similarly, in view of the limiting effect of the lower limit height plate 334, the outer contour of the lower port screw cover can be effectively prevented from being damaged and deformed due to the excessive extrusion pressure from the first lower conical top contact wheel 332 and the second lower conical top contact wheel 333.

[0049] Furthermore, by Fig. 9 , 13It can also be clearly seen from the figure that the upper drive unit 24 includes an upper single-axis steering gear 241 and an upper gear transmission system 242. The upper single-axis steering gear 241 is detachable to achieve fixation with the upper mounting frame 22, and the torque generated by the upper gear transmission system 242 is transmitted to the upper fork 231. The lower drive unit 34 includes a lower single-axis steering gear 341 and a lower gear transmission system 342. The lower single-axis steering gear 341 is detachable to achieve fixation with the lower mounting frame 32, and the torque generated by the lower gear transmission system 342 is transmitted to the lower fork 331. Compared with the traditional rotary motor and servo motor drive method, both the upper drive unit 241 and the lower drive unit 34 have an extremely compact design structure, are easy to use, and do not require complex mechanical parts or high-precision assembly, thereby reducing production costs.

[0050] like Figure 7 As shown in , the upper cantilever platform 21 is preferably a combined assembly structure, which is mainly composed of several parts such as the upper platform body 211, the first upper cantilever beam 212 and the second upper cantilever beam 213. The first upper cantilever beam 212 and the second upper cantilever beam 213 are respectively in contact with the left and right side walls of the upper platform body 211, and are fixed as a whole by means of upper screws 214. Fig.11 As shown in , the lower cantilever platform 31 is preferably a combined assembly structure, which is mainly composed of several parts such as the lower platform body 311, the first lower cantilever beam 312 and the second lower cantilever beam 313. The first lower cantilever beam 312 and the second lower cantilever beam 313 are respectively in contact with the left and right side walls of the lower platform body 311, and are fixed as a whole by means of the lower screw assembly 314. In this way, on the one hand, it is convenient to perform a retrofit design on the upper cantilever platform 21 and the lower cantilever platform 31 according to actual design requirements, which is conducive to reducing the difficulty of subsequent modification of the medical gas logistics bottle capping machine; on the other hand, when the upper cantilever platform 21 and the lower cantilever platform 31 are damaged, it is convenient to perform a replacement operation, and only part of the structural body needs to be replaced, without the need for overall replacement, which is conducive to reducing subsequent maintenance costs.

[0051] As is known, according to design common sense, the guide assembly 4 can adopt a variety of design structures to achieve the guidance of the displacement direction of the upper cantilever platform 21 and the lower cantilever platform 31. However, a technical solution with a simple design structure, easy implementation, and good guiding performance is recommended here, specifically: Fig.14 , 15As shown in , the guide assembly 4 is mainly composed of several parts such as a slide rail 41, an upper slider 42, a lower slider 43, an upper sliding assembly 44 and a lower sliding assembly 45. The slide rail 41 is detachably fixed to the right side wall of the frame 1 by means of a plurality of screws. The upper slider 42 and the lower slider 43 used in pair with the slide rail 41 respectively correspond to the second upper cantilever beam 213 and the second lower cantilever beam 313 as the installation basis. A sliding groove 11 is provided on the other side of the frame 1. The upper sliding assembly 44 and the lower sliding assembly 45, which are both inserted into the sliding groove 11 and can slide in the up and down directions, respectively correspond to the first upper cantilever beam 212 and the first lower cantilever beam 312 as the installation basis.

[0052] In the above technical scheme, by selecting different guide structures for the left and right sides, that is, the left side selects the sliding groove 11 in combination with the upper sliding assembly 44 and the lower sliding assembly 45, and the right side selects the slide rail 41 in combination with the upper slider 42 and the lower slider 43, it can effectively ensure that the upper cover opening mechanism 2 and the lower cover opening mechanism 3 can be quickly and correctly assembled with the frame 1, even when the molding size error or shape error of the upper cantilever platform 21 and the lower cantilever platform 31 are large.

[0053] like Figure 4 , 16 As shown in Figures 1 and 17, the upper sliding assembly 44 is composed of a first upper sliding block 441 and a second upper sliding block 442 arranged in sequence along the up-down direction. The first upper cantilever beam 212 is composed of a first upper cantilever beam body 2121 as the installation base of the first upper sliding block 441 and an upper elastic lower extension 2122 as the installation base of the second upper sliding block 442. The upper elastic lower extension 2122 is formed by continuing to extend downward from the bottom wall of the first upper cantilever beam body 2121 and undergoing at least two bends (such as Figure 8 ). The lower sliding assembly 45 is composed of a first lower sliding block 451 and a second lower sliding block 452 arranged in sequence along the up-down direction. The first lower cantilever beam 312 is composed of a first lower cantilever beam body 3121 as a mounting base for the first lower sliding block 451 and a lower elastic lower extension 3122 as a mounting base for the second lower sliding block 452. The lower elastic lower extension 3122 is formed by continuing to extend downward from the bottom wall of the first lower cantilever beam body 3121 and undergoing at least two bends (as shown in FIG. 1 ). Fig.12). With respect to the first upper cantilever beam 212, the second upper sliding block 442 is a non-rigid connection. With respect to the first lower cantilever beam 312, the second lower sliding block 452 is a non-rigid connection. In this way, it is not only effectively ensured that the upper cantilever platform 21 and the lower cantilever platform 31 always maintain good guidance in the process of performing displacement movement in the up and down directions due to the reverse driving force, thereby ensuring that the upper cover assembly 23 and the lower cover assembly 33 accurately cap the upper and lower ports of the pneumatic tube transmission bottle, but also helps to ensure that the upper cover opening mechanism 2 and the lower cover opening mechanism 3 can be quickly and correctly assembled with the frame 1.

[0054] Finally, it should be noted that as a structural preference, Fig.18 , 19 As shown in the figure, the power unit 5 is mainly composed of a load-bearing frame 51, a reduction motor 52, a transmission gear 53, a left rack 54 and a right rack 55. The load-bearing frame 51 is used to carry the reduction motor 52, and it is detachable to achieve fixation with the frame 1. The transmission gear 53 performs circumferential rotation under the action of the torque from the reduction motor 52, and the left rack 54 meshing with the transmission gear 53 is able to drag the lower cover opening mechanism 3, and at the same time, the right rack 55 meshing with the transmission gear 53 is able to reversely drag the upper cover opening mechanism 2.
