Description

Technical Field

[0001] The utility model relates to the technical field of pneumatic logistics transmission bottle conveying, in particular to an opening machine for a medical pneumatic logistics transmission bottle. Background Technique

[0002] In the past, the transmission operation of medical devices mainly relied on manual labor. However, due to the insufficient understanding of the transfer personnel, they were unable to understand many related problems, and coupled with the poor communication with medical staff, a series of problems were bound to occur, such as incorrect transfer destinations, poor transfer timeliness, and human error classification, etc., which were extremely likely to cause serious medical safety problems.

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

[0004] Regarding the current industry situation, as Figure 1 、 2 、shown in 3, most medical pneumatic logistics transmission bottles are of the standard double-screw cap type, that is, openings are provided at both ends of the bottle body, and the caps are buckled and sealed by means of screw caps. Different from the most common screw-rotating caps, the screw caps of medical pneumatic logistics transmission bottles are composed of a cap body and an insertion post. The insertion post extends inward from the inner side wall of the cap body, is eccentrically arranged, and is close to the outer contour of the cap body. An insertion hole for inserting the insertion post is opened on the end face of the bottle body. When an opening operation needs to be performed on the screw cap, the cap body is laterally pushed or rotated, and the cap body deflects around the insertion hole until the sealing of the opening of the bottle body is released. In order to further improve the transmission efficiency of the medical pneumatic logistics transmission system, the R & D personnel initially envisioned to equip it with an automatic opening device. However, in the existing technology, although a wide variety of opening mechanisms or opening devices can be retrieved, most of the applicable objects are conventional screw-rotating caps or flip caps, and it is difficult to be applicable to standard double-screw cap type medical pneumatic logistics transmission bottles. Therefore, it is urgent for technical personnel to solve the above problems. Content of the Utility Model

[0005] Therefore, in view of the above existing problems and defects, the designers of the present utility model collected relevant materials, through multi-party evaluation and consideration, and through continuous experiments and modifications by technical personnel with many years of R & D experience in this industry, finally led to the emergence of the opening machine for the medical pneumatic logistics transmission bottle.

[0006] To solve the above technical problems, the utility model relates to an opening machine for the lid of a medical pneumatic logistics transmission bottle, which comprises a frame, an upper lid-opening mechanism, a lower lid-opening mechanism, a guiding component and a power unit. The upper lid-opening mechanism and the lower lid-opening mechanism are arranged oppositely along the up-and-down direction and are both borne by the frame. The power unit takes the frame as the installation base. The movement directions of the upper lid-opening mechanism and the lower lid-opening mechanism are rectified by the guiding component, and they synchronously perform reverse displacement movements under the driving force from the power unit, so as to approach or move away from the medical pneumatic logistics transmission bottle.

[0007] As a further improvement of the technical solution disclosed by the utility model, the upper lid-opening mechanism comprises an upper cantilever platform, an upper mounting frame, an upper lid-pushing component and an upper driving part. The lower lid-opening mechanism comprises a lower cantilever platform, a lower mounting frame, a lower lid-pushing component and a lower driving part. The upper cantilever platform and the lower cantilever platform perform displacement movements directionally under the coordinated action of the guiding component and the power unit. The upper mounting frame and the lower mounting frame are respectively and detachably fixed to the upper cantilever platform and the lower cantilever platform in a one-to-one correspondence manner. The upper lid-pushing component is arranged directly below the upper cantilever platform, and the lower lid-pushing component is arranged directly above the lower cantilever platform. The upper driving part is used to drive the upper lid-pushing component to perform a deflection movement, so that the screw cap located at the upper port of the medical pneumatic logistics transmission bottle can be opened / reset, and it takes the upper mounting frame as the assembly base. The lower driving part is used to drive the lower lid-pushing component to perform a deflection movement, so that the screw cap located at the lower port of the medical pneumatic logistics transmission bottle can be opened / reset, and it takes the lower mounting frame as the assembly base.

[0008] As a further improvement of the technical solution disclosed by the utility model, the upper lid-pushing component comprises an upper fork, a first upper conical top contact wheel and a second upper conical top contact wheel. The upper fork directly performs a deflection movement under the action of the torque of rotation from the upper driving part.

The lower lid-pushing component comprises a lower fork, a first lower conical top contact wheel and a second lower conical top contact wheel. The lower fork directly performs a deflection movement under the action of the torque of rotation from the lower driving part. The first lower conical top contact wheel and the second lower conical top contact wheel are respectively detachably mounted at both ends of the lower fork.

[0009] As a further improvement of the technical solution disclosed by the utility model, under the action of the frictional force of the screw cap of the medical pneumatic logistics transmission 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 rotation movements around their respective central axes.

The lower height limiting plate is in contact with the top wall of the lower fork and is detachably fixed as a whole.

[0011] As a further improvement to the disclosed technical solution of the present utility model, both the upper height limiting plate and the lower height limiting plate are made of elastomeric plastic. During the process that the first upper conical top contact wheel and the second upper conical top contact wheel approach and press against the screw cap at the upper port of the medical pneumatic logistics transmission bottle, the upper height limiting plate undergoes self-adaptive elastic deformation due to the pressure. During the process that the first lower conical top contact wheel and the second lower conical top contact wheel approach and press against the screw cap at the lower port of the medical pneumatic logistics transmission bottle, the lower height limiting plate undergoes self-adaptive elastic deformation due to the pressure.

[0012] As a further improvement to the disclosed technical solution of the present utility model, the upper driving part includes an upper single-axis servo motor and an upper gear transmission system. The upper single-axis servo motor is detachably fixed to the upper mounting bracket, and the rotational torque generated by the upper gear transmission system is transmitted to the upper cover shifting assembly. The lower driving part includes a lower single-axis servo motor and a lower gear transmission system. The lower single-axis servo motor is detachably fixed to the lower mounting bracket, and the rotational torque generated by the lower gear transmission system is transmitted to the lower cover shifting assembly.

[0013] As a further improvement to the disclosed technical solution of the present utility model, the upper cantilever platform is a combined assembled structure, which includes an upper platform main 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 main body and are fixed as a whole by means of an upper screw assembly. The lower cantilever platform is a combined assembled structure, which includes a lower platform main 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 main body and are fixed as a whole by means of a lower screw assembly.

[0014] As a further improvement to the disclosed technical solution of the present utility model, the guiding assembly includes a slide rail, an upper slide block, a lower slide block, 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 slide block and the lower slide block paired with the slide rail respectively use the second upper cantilever beam and the second lower cantilever beam as the installation bases. A sliding groove is provided on the other side of the frame. The upper sliding assembly and the lower sliding assembly that are respectively inserted into the sliding groove and can slide in the up and down direction respectively use the first upper cantilever beam and the first lower cantilever beam as the installation bases.

[0015] As a further improvement to the disclosed technical solution of the present utility model, 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 main body serving as the installation foundation of the first upper sliding block and an upper elastic downward extension body serving as the installation foundation of the second upper sliding block. The upper elastic downward extension body extends downward from the bottom wall of the first upper cantilever beam main body and is formed by 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 main body serving as the installation foundation of the first lower sliding block and a lower elastic downward extension body serving as the installation foundation of the second lower sliding block.

[0016] As a further improvement to the disclosed technical solution of the present utility model, the power unit includes a bearing frame, a reduction motor, a transmission gear, a left rack, and a right rack. The bearing frame is used to carry the reduction motor and is detachably fixed to the machine frame. The transmission gear performs a circumferential rotational movement under the action of the rotational torque from the reduction motor. The left rack engaged with the transmission gear drags the lower bottle-opening mechanism, and at the same time, the right rack engaged with the transmission gear drags the upper bottle-opening mechanism in the opposite direction.

[0017] The working principle of the medical pneumatic logistics transmission bottle cap opener disclosed by the present utility model is generally as follows: When it is necessary to perform a discharging operation on a medical pneumatic logistics transmission bottle, first, it is shifted to the discharging station, and the bottle body is clamped and fixed. Then, the power unit is started, and with the assistance of the guiding assembly, the upper bottle-opening mechanism and the lower bottle-opening mechanism perform displacement movements under the driving force from the power unit until they respectively abut against the upper port cap and the lower port cap of the medical pneumatic logistics transmission bottle. Subsequently, the upper bottle-opening mechanism acts to apply a lateral rotational torque to the upper port cap, and the upper port cap performs a circumferential rotational movement around its plug until the sealing of the upper port of the medical pneumatic logistics transmission bottle is completely removed. At the same time, the lower bottle-opening mechanism acts to apply a lateral rotational torque to the lower port cap, and the lower port cap performs a circumferential rotational movement around its plug until the sealing of the lower port of the medical pneumatic logistics transmission bottle is completely removed.

[0018] In practical applications, the medical pneumatic logistics transmission bottle cap opener disclosed by the present utility model can achieve at least the following beneficial technical effects: specifically,

Detailed implementation mode

[0042] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "left", "right", "upper", "lower", "front", "rear", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0043] Figure 1 , 2 , and a medical pneumatic logistics transmission bottle in the industry is commonly shown in FIGS. 1 and 3. It is a standard double-screw cap type, that is, openings are provided 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 cap body and an insertion post. The insertion post extends inward from the inner side wall of the cap body, is eccentrically arranged, and is close to the outer contour of the cap body. An insertion hole for inserting the insertion post is opened on the end face of the bottle body. When it is necessary to perform an opening operation on the screw cap, the cap body is laterally pushed or rotated, and the cap body can perform a deflection movement around the insertion hole until the sealing of the opening of the bottle body is released.

[0044] The following is a further detailed description of the present invention in conjunction with specific embodiments. Figure 4 , Figure 5 The three-dimensional schematic diagrams of two different perspectives of the medical gas tube logistics bottle decapping machine disclosed in the utility model are respectively shown. 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 flow bottle capping machine disclosed in the utility model 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. Figure 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 movements directionally under the coordinated action of the guiding assembly 4 and the power unit 5. The upper mounting frame 22 and the lower mounting frame 32 are respectively and detachably fixed to the upper cantilever platform 21 and the lower cantilever platform 31 in a one-to-one correspondence. The upper cover flipping assembly 23 is arranged directly below the upper cantilever platform 21, and the lower cover flipping assembly 33 is arranged directly above the lower cantilever platform 31. The upper driving part 24 is used to drive the upper cover flipping assembly 23 to perform a deflection movement, so that the screw cap located at the upper port of the medical pneumatic logistics transmission bottle can be opened / reset, and it is assembled based on the upper mounting frame 22. The lower driving part 34 is used to drive the lower cover flipping assembly 33 to perform a deflection movement, so that the screw cap located at the lower port of the medical pneumatic logistics transmission bottle can be opened / reset, and it is assembled based on the lower mounting frame 32. As Figure 9 shown, the upper cover flipping assembly 23 is mainly composed of an upper fork 231, a first upper conical top contact wheel 232, a second upper conical top contact wheel 233 and other parts. The upper fork 231 directly receives the rotational torque from the upper driving part 24 and performs a deflection movement. The first upper conical top contact wheel 232 and the second upper conical top contact wheel 233 are respectively detachably mounted at both ends of the upper fork 231. As Figure 13As shown in the figure, the lower cover-opening assembly 33 mainly consists of several parts such as a lower fork 331, a first lower conical top contact wheel 332, and a second lower conical top contact wheel 333. The lower fork 331 is directly affected by the rotational torque from the lower driving part 34 and performs a deflection movement. The first lower conical top contact wheel 332 and the second lower conical top contact wheel 333 are respectively detachably mounted at both ends of the lower fork 331. Thus, when it is necessary to perform an opening operation on the medical pneumatic logistics transmission bottle, first, the upper cover-opening assembly 23 and the lower cover-opening assembly 33 approach the medical pneumatic logistics transmission bottle synchronously due to the reverse driving force until the first upper conical top contact wheel 232 and the second upper conical top contact wheel 233 press against 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 press against the outer contour surface of the lower port screw cap. Then, the upper 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 fork 231 coincides with the central axis of the upper port plug of the medical pneumatic logistics transmission bottle. The first upper conical top contact wheel 232 and the second upper conical top contact wheel 233 cooperate to apply a rotational torque to the upper port screw cap, and the upper port screw cap can perform a circumferential rotational movement around its plug until the sealing of the upper port of the medical pneumatic logistics transmission 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 lower port plug of the medical pneumatic logistics transmission 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 screw cap, and the lower port screw cap can perform a circumferential rotational movement around its plug until the sealing of the lower port of the medical pneumatic logistics transmission bottle is completely released. Various items required in medical work can fall from the medical pneumatic logistics transmission bottle by themselves.

[0047] In the initial design, both the first upper conical top contact wheel 232 and the second upper conical top contact wheel 233 are fixedly mounted at both ends of the upper fork 231 without rotation, and both the first lower conical top contact wheel 332 and the second lower conical top contact wheel 333 are fixedly mounted at both ends of the lower fork 331 without rotation. However, in actual applications, the following problems are found: Taking the upper port screw cap of the medical pneumatic logistics transmission bottle as an example, when it is necessary to perform an opening operation on it, during the process that the upper port screw cap performs a circumferential rotational movement around its plug due to the rotational torque, 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, and the outer contour of the upper port screw cap is extremely easy to be scratched and worn due to the sliding friction force. In view of this, as a further optimization of the above technical solution, such as Figure 9 、 13As shown, 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. In the case of being subjected to the frictional force from the cap of the medical pneumatic logistics transmission 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 all freely perform circumferential rotational motion around their respective central axes. In this way, on the one hand, it can effectively reduce the relative friction force value received by the outer contour of the cap during the opening process, thereby avoiding the occurrence of accelerated damage due to long-term wear; on the other hand, it is beneficial to automatically correct the relative position and tilting posture of the medical pneumatic logistics transmission bottle, ensuring that the upper cap-pulling assembly 23 and the lower cap-pulling assembly 33 can correctly apply a rotational torque to the caps at the upper and lower ports of the medical pneumatic logistics transmission bottle.

[0048] From Figure 9 , 13As can also be clearly seen from the figure, the upper dial cover assembly 23 is further provided with an upper height limiting plate 234. The lower dial cover assembly 33 is further provided with a lower height limiting plate 334. The upper height limiting plate 234 is in contact with the bottom wall of the upper fork 231 and is detachably fixed as a whole. The lower height limiting plate 334 is in contact with the top wall of the lower fork 331 and is detachably fixed as a whole. Both the upper height limiting plate 234 and the lower height limiting plate 334 are made of elastomeric plastic. In this way, during the process that the first upper conical top contact wheel 232 and the second upper conical top contact wheel 233 approach and press against the screw cap of the upper port of the medical pneumatic logistics transmission bottle, the upper height limiting plate 234 undergoes self-adaptive elastic deformation due to pressure. During the process that the first lower conical top contact wheel 332 and the second lower conical top contact wheel 333 approach and press against the screw cap of the lower port of the medical pneumatic logistics transmission bottle, the lower height limiting plate 334 undergoes self-adaptive elastic deformation due to pressure. In this way, on the one hand, since the upper height limiting plate 234 and the lower height limiting plate 334 are elastomers and are respectively in pressure contact with the screw caps of the upper and lower ports of the medical pneumatic logistics transmission bottle, during the process of opening the cap, in addition to 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 that play the main role, a part of the rotational torque can also be applied to the upper and lower port screw caps through the upper height limiting plate 234 and the lower height limiting plate 334 respectively, ensuring the smooth implementation and development of the cap opening operation; on the other hand, due to the limiting effect of the upper height limiting plate 234, the phenomenon that the outer contour of the upper port screw cap is damaged and deformed due to the excessive squeezing pressure from the first upper conical top contact wheel 232 and the second upper conical top contact wheel 233 can be effectively avoided. Similarly, due to the limiting effect of the lower height limiting plate 334, the phenomenon that the outer contour of the lower port screw cap is damaged and deformed due to the excessive squeezing pressure from the first lower conical top contact wheel 332 and the second lower conical top contact wheel 333 can be effectively avoided.

[0049] Furthermore, from Figure 9 , 13As can also be clearly seen from the figure, the upper drive unit 24 includes an upper single-axis servo 241 and an upper gear transmission system 242. The upper single-axis servo 241 is detachably fixed to the upper mounting bracket 22, and the rotational 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 servo 341 and a lower gear transmission system 342. The lower single-axis servo 341 is detachably fixed to the lower mounting bracket 32, and the rotational torque generated by the lower gear transmission system 342 is transmitted to the lower fork 331. Compared with the traditional driving methods of rotary motors and servo motors, both the upper drive unit 241 and the lower drive unit 34 have an extremely compact design structure, are convenient to use, and do not require complex mechanical components or high-precision assembly, thus reducing the production cost.

[0050] As Figure 7 shown in the figure, the upper cantilever platform 21 is preferably a combined assembled structure, which mainly consists of an upper platform main body 211, a first upper cantilever beam 212, a second upper cantilever beam 213 and other parts. 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 main body 211, and are fixed into one body by means of the upper screw 214 assembly. As Figure 11 shown in the figure, the lower cantilever platform 31 is preferably a combined assembled structure, which mainly consists of a lower platform main body 311, a first lower cantilever beam 312, a second lower cantilever beam 313 and other parts. 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 main body 311, and are fixed into one body by means of the lower screw assembly 314. In this way, on the one hand, it is convenient to perform retrofit design on the upper cantilever platform 21 and the lower cantilever platform 31 according to actual design requirements, which is beneficial to reducing the subsequent retrofit difficulty of the medical pneumatic logistics transmission bottle capping machine; on the other hand, when the upper cantilever platform 21 and the lower cantilever platform 31 are damaged, it is beneficial to perform replacement operation, and only some structural main bodies need to be replaced, rather than the whole, which is beneficial to reducing the subsequent maintenance cost.

[0051] It is known that, according to design common sense, the guiding assembly 4 can adopt various design structures to realize the guiding of the displacement directions of the upper cantilever platform 21 and the lower cantilever platform 31. However, a technical solution with a simple design structure, easy to implement and good guiding performance is recommended here. Specifically: As Figure 14 、 15As shown in the figure, the guiding component 4 is mainly composed of a slide rail 41, an upper slider 42, a lower slider 43, an upper sliding component 44, and a lower sliding component 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 paired with the slide rail 41 respectively use the second upper cantilever beam 213 and the second lower cantilever beam 313 as the installation bases. A sliding groove 11 is provided on the other side of the frame 1. The upper sliding component 44 and the lower sliding component 45 that are both inserted into the sliding groove 11 and can slide in the up and down direction respectively use the first upper cantilever beam 212 and the first lower cantilever beam 312 as the installation bases.

[0052] In the above technical solution, by selecting different guiding structures on the left and right sides, that is, the combination application mode of the sliding groove 11 with the upper sliding component 44 and the lower sliding component 45 is selected on the left side, and the combination application mode of the slide rail 41 with the upper slider 42 and the lower slider 43 is selected on the right side, 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 forming size error or shape error of the upper cantilever platform 21 and the lower cantilever platform 31 are both relatively large.

[0053] As Figure 4 、 16 、17 shown, the upper sliding component 44 is composed of a first upper sliding block 441 and a second upper sliding block 442 arranged in sequence along the up and down direction. The first upper cantilever beam 212 is composed of a first upper cantilever beam main body 2121 serving as the installation base of the first upper sliding block 441 and an upper elastic downward extension body 2122 serving as the installation base of the second upper sliding block 442. The upper elastic downward extension body 2122 extends downward continuously from the bottom wall of the first upper cantilever beam main body 2121 and is formed by at least two bends (as Figure 8 shown). The lower sliding component 45 is composed of a first lower sliding block 451 and a second lower sliding block 452 arranged in sequence along the up and down direction. The first lower cantilever beam 312 is composed of a first lower cantilever beam main body 3121 serving as the installation base of the first lower sliding block 451 and a lower elastic downward extension body 3122 serving as the installation base of the second lower sliding block 452 (as Figure 12As shown in [figure reference]. The lower elastic downward extension body 3122 extends downward continuously from the bottom wall of the first lower cantilever beam body 3121 and is formed through at least two bends. Relative to the first upper cantilever beam 212, the second upper sliding block 442 is in a non-rigid connection mode. Relative to the first lower cantilever beam 312, the second lower sliding block 452 is in a non-rigid connection mode. In this way, not only is it effectively ensured that the upper cantilever platform 21 and the lower cantilever platform 31 always maintain good guiding properties during the displacement movement process along the up and down direction due to the action of reverse driving forces, thereby ensuring the precise pressing on the upper and lower ports of the pneumatic logistics transmission bottle by the upper cover-pushing component 23 and the lower cover-pushing component 33, but also it is conducive to ensuring 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 also be noted that, as a structural preference, as Figure 18 , 19 shown in [figure reference], the power unit 5 mainly consists of a load-bearing frame 51, a reduction motor 52, a transmission gear 53, a left rack 54, and a right rack 55, etc. Among them, the load-bearing frame 51 is used to carry the reduction motor 52, and it is fixed to the frame 1 in a detachable manner. The transmission gear 53 performs a circumferential rotational movement under the action of the rotational torque from the reduction motor 52. The left rack 54 engaged with the transmission gear 53 drags the lower cover-opening mechanism 3, and at the same time, the right rack 55 engaged with the transmission gear 53 drags the upper cover-opening mechanism 2 in the opposite direction.
