Description

Technical Field

[0001] This utility model belongs to the field of medical transportation equipment technology, and specifically relates to a pneumatic drone medical bag ejection device. Background Technology

[0002] In modern medical rescue systems, drones, with their unique advantages of rapid response, flexibility, and ability to overcome terrain limitations, have become a crucial link in the transportation of medical supplies and emergency rescue scenarios in remote areas. As the core execution unit of the drone medical transportation system, the performance of the medical package ejection device directly determines the accuracy and timeliness of the delivery of supplies, and has a decisive impact on the success rate of rescue.

[0003] To ensure the flight stability of the medical pack during ejection, the securing mechanism must closely conform to the pack's contours to provide guidance and prevent deviation or tipping. However, this strong geometric dependence means the securing mechanism can only accommodate a single size of medical pack. When faced with medical packs of different sizes, the mechanism cannot provide effective securing, severely limiting the overall applicability of the ejection device. Utility Model Content

[0004] To address the issue that the fixing mechanism on the ejection device can only fix a single size of medical kit, this utility model proposes a pneumatic drone medical kit ejection device to overcome the aforementioned technical problems existing in the relevant technologies.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a pneumatic drone medical bag ejection device, including a drone, a storage frame fixedly installed on the bottom of the drone, a clamping component inside the storage frame, a squeezing component between the clamping ends of the clamping component, an ejection component inside the storage frame, a limiting component at the bottom of the squeezing component, a pushing component at the top of the squeezing component, and the pushing component being poweredly connected to the limiting component.

[0007] The clamping component is used to clamp the two sides of the medical bag, the squeezing component is used to squeeze the top of the medical bag, the limiting component is used to limit the front of the medical bag, and the pushing component is used to push the limiting component upward so that the medical bag can be ejected normally from the inside of the storage frame.

[0008] Furthermore, the clamping assembly includes a bidirectional screw, which is rotatably connected to the storage frame. Two clamping frames are threadedly connected to the outer surface of the bidirectional screw. Several clamping rollers are rotatably connected inside the two clamping frames. A guide rod is fixedly connected between the two sides of the inner wall of the storage frame. The clamping frame is movably connected to the guide rod. Several support rollers are rotatably connected between the two sides of the inner wall of the storage frame.

[0009] Furthermore, the extrusion assembly includes extrusion frames, two of which are stacked inside the storage frame. Several extrusion rollers are rotatably connected inside the two extrusion frames. A connecting plate is fixedly installed on the top of the two extrusion frames. A lifting screw is rotatably connected to the top of the connecting plate. The lifting screw is threadedly connected to the storage frame. A limit rod is fixedly connected between the top and bottom of the inner wall of the storage frame. The extrusion frame is movably connected to the limit rod.

[0010] Furthermore, the ejection assembly includes an ejection pneumatic cylinder, which is fixedly installed on the back of the storage frame. The piston rod of the ejection pneumatic cylinder extends into the interior of the storage frame and is fixedly connected to an ejection plate, which is disposed between two compression frames.

[0011] Furthermore, the limiting component includes an adjusting screw, which is rotatably connected to the top of the extrusion frame. An adjusting frame is threadedly connected to the outer surface of the adjusting screw. A connecting rod is movably connected inside the adjusting frame. A limiting frame is movably connected to the outer surface of the connecting rod. A guide plate is provided on the top of the extrusion frame. A movable groove is provided on one side of the limiting frame. The limiting frame is sleeved on the outer surface of the guide plate through the movable groove.

[0012] Furthermore, the pushing assembly includes a T-shaped fixing rod, multiple T-shaped fixing rods are fixedly connected to the top of the extrusion frame, the guide plate is movably connected to the T-shaped fixing rod, a return spring is fixedly connected between the guide plate and the extrusion frame, a wedge-shaped column is provided at the top of the extrusion frame, and a pushing plate is provided on one side of the wedge-shaped column.

[0013] Furthermore, a T-shaped support column is fixedly connected to the top of the extrusion frame, the wedge-shaped column is movably connected to the T-shaped support column, and a push spring is provided on the outer side of the T-shaped support column.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model drives the clamping component, the squeezing component, and the limiting component, enabling the clamping end, the squeezing end, and the limiting end to adaptively conform to the outer surface of the medical pack. The setting of dynamic position adjustment based on the actual size of the medical pack can not only achieve precise positioning and firm fixation of medical packs of different specifications, but also form a stable guiding structure during ejection, effectively preventing the medical pack from shifting or flipping. The above settings significantly improve the adaptability of the ejection device to medical packs of multiple specifications, greatly enhancing the universality of the equipment in diverse medical transportation scenarios.

[0016] 2. In this invention, when launching a medical pack using a launcher plate, the moving launcher plate pushes a wedge-shaped column via a pusher plate. At this time, the guide plate, lifted by the wedge-shaped column, can move the limiting frame upwards. When the wedge-shaped column is completely at the bottom of the guide plate, the limiting frame also moves completely out from the front of the medical pack. At this point, the launcher plate contacts the medical pack and launches it. This design ensures the overall stability of the medical pack during transportation. Furthermore, during the launch of the medical pack, as the launcher plate moves, the limiting frame automatically moves upwards and releases its restraint on the medical pack. The above process can be performed normally when launching medical packs of different sizes, thus improving the practicality of the device.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0029] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0030] Please see Figures 1-7 As shown, this utility model is a pneumatic drone medical bag ejection device, including a drone 1. A storage frame 2 is fixedly installed on the bottom of the drone 1. A clamping component 3 is provided inside the storage frame 2. A squeezing component 4 is provided between the clamping ends of the clamping component 3. An ejection component 5 is provided inside the storage frame 2. A limiting component 6 is provided at the bottom of the squeezing component 4. A pushing component 7 is provided at the top of the squeezing component 4. The pushing component 7 is poweredly connected to the limiting component 6.

[0031] The clamping component 3 is used to clamp the two sides of the medical bag, the squeezing component 4 is used to squeeze the top of the medical bag, the limiting component 6 is used to limit the front of the medical bag, and the pushing component 7 is used to push the limiting component 6 upward so that the medical bag can be ejected normally from the inside of the storage frame 2.

[0032] By placing the medical pack inside the storage frame 2, then driving the clamping component 3 so that the two clamping ends come into contact with the sides of the medical plate, then driving the squeezing component 4 so that the squeezing end comes into contact with the top of the medical pack, and finally driving the limiting component 6 so that the limiting component 6 and the limiting end come into contact with the front of the medical pack, the medical pack can be fixed inside the storage frame 2.

[0033] By driving the clamping component 3, the squeezing component 4, and the limiting component 6, the clamping end, squeezing end, and limiting end can adaptively conform to the outer surface of the medical pack. The setting of dynamic position adjustment based on the actual size of the medical pack can not only achieve precise positioning and firm fixation of medical packs of different specifications, but also form a stable guiding structure during ejection, effectively preventing the medical pack from shifting or flipping. The above settings significantly improve the adaptability of the ejection device to medical packs of multiple specifications, and greatly enhance the versatility of the equipment in diverse medical transportation scenarios.

[0034] In one embodiment, for the bidirectional screw 301, the clamping assembly 3 includes a bidirectional screw 301, which is rotatably connected to the storage frame 2. Two clamping frames 302 are threadedly connected to the outer surface of the bidirectional screw 301. A plurality of clamping rollers 303 are rotatably connected inside the two clamping frames 302. A guide rod 304 is fixedly connected between the two sides of the inner wall of the storage frame 2. The clamping frames 302 are movably connected to the guide rod 304. A plurality of support rollers 305 are rotatably connected between the two sides of the inner wall of the storage frame 2.

[0035] By placing the medical pack on top of several support rollers 305 and then rotating the bidirectional screw 301, the two clamping frames 302 can move simultaneously to both sides of the medical pack under the drive of the bidirectional screw 301 and the guidance of the guide rod 304. When the clamping rollers 303 on the two clamping frames 302 come into contact with the medical pack, the rotation of the bidirectional screw 301 stops. The arrangement of the support rollers 305 and the clamping rollers 303 makes the friction between the medical pack and the two clamping frames 302 and the bottom of the inner wall of the storage frame 2 smaller when the medical pack is ejected, so that the medical pack can be ejected better from the inner wall of the storage frame 2.

[0036] In one embodiment, the extrusion assembly 4 includes an extrusion frame 401. Two extrusion frames 401 are stacked inside the storage frame 2. Several extrusion rollers 402 are rotatably connected inside the two extrusion frames 401. A connecting plate 405 is fixedly installed on the top of the two extrusion frames 401. A lifting screw 403 is rotatably connected to the top of the connecting plate 405. The lifting screw 403 is threadedly connected to the storage frame 2. A limiting rod 404 is fixedly connected between the top and bottom of the inner wall of the storage frame 2. The extrusion frame 401 is movably connected to the limiting rod 404.

[0037] After the medical pack is placed on top of the support roller 305, it is pushed so that the back of the medical pack comes into contact with the limiting rod 404. After the contact and fixation of both sides of the medical pack is completed, the lifting screw 403 is rotated. At this time, the lifting screw 403 can push the two extrusion frames 401 downward through the connecting plate 405, so that the extrusion roller 402 at the bottom of the extrusion frame 401 can come into contact with the top of the medical pack. Since the limiting rod 404 can limit and guide the moving extrusion frame 401, the extrusion frame 401 is not easy to shake when it is raised and lowered.

[0038] In one embodiment, the ejection assembly 5 includes an ejection pneumatic cylinder 501, which is fixedly installed on the back of the storage frame 2. The piston rod of the ejection pneumatic cylinder 501 extends into the interior of the storage frame 2 and is fixedly connected to an ejection plate 502, which is disposed between two compression frames 401.

[0039] By driving the ejection pneumatic cylinder 501, the piston on the inner wall of the ejection pneumatic cylinder 501 drives the ejection plate 502 to move rapidly. At this time, the rapidly moving ejection plate 502 can eject the medical pack and make the medical pack ejected from the inside of the storage frame 2. By setting the ejection plate 502 between the two compression frames 401, the ejection plate 502 can complete the ejection of the medical pack normally, regardless of the size of the medical pack being compressed by the compression frames 401.

[0040] In one embodiment, the limiting component 6 includes an adjusting screw 601, which is rotatably connected to the top of the extrusion frame 401. An adjusting bracket 602 is threadedly connected to the outer surface of the adjusting screw 601. A connecting rod 603 is movably connected inside the adjusting bracket 602. A limiting bracket 604 is movably connected to the outer surface of the connecting rod 603. A guide plate 605 is provided on the top of the extrusion frame 401. A movable groove 606 is provided on one side of the limiting bracket 604. The limiting bracket 604 is sleeved on the outer surface of the guide plate 605 through the movable groove 606.

[0041] When the compression roller 402 at the bottom of the compression frame 401 contacts the top of the medical pack, the limiting frame 604 can be directly positioned on the front of the medical pack. Then, the adjusting screw 601 is rotated, causing the adjusting frame 602 to move. The moving adjusting frame 602, via the connecting rod 603, can move the limiting frame 604 between the two compression frames 401. When the limiting frame 604 contacts the front of the medical pack, the limiting frame 604 and the limiting rod 404 work together to limit the front and rear movement of the medical pack, thus… This design prevents the medical kit from swaying back and forth during transport. The adjusting frame 602 can move on the outer surface of the guide plate 605 via the movable groove 606. When the medical kit needs to be ejected, the guide plate 605 is moved upward. The moving guide plate 605 can drive the limiting frame 604 to slide on the connecting rod 603. When the guide plate 605 moves to the predetermined position, the limiting frame 604 no longer obstructs the front of the medical kit, allowing the medical kit to be ejected normally from the inside of the storage frame 2.

[0042] In one embodiment, the pushing component 7 includes a T-shaped fixing rod 701, multiple T-shaped fixing rods 701 are fixedly connected to the top of the extrusion frame 401, the guide plate 605 is movably connected to the T-shaped fixing rods 701, a return spring 702 is fixedly connected between the guide plate 605 and the extrusion frame 401, a wedge-shaped post 703 is provided on the top of the extrusion frame 401, and a pushing plate 704 is provided on one side of the wedge-shaped post 703.

[0043] The return spring 702 can pull the guide plate 605 downwards. This design ensures that when the limiting frame 604 limits the front of the medical bag, the guide plate 605 will not move arbitrarily, thus guaranteeing the limiting effect of the limiting frame 604. Simultaneously, when the ejector plate 502 ejects the medical bag, the moving ejector plate 502 can push the wedge-shaped post 703 through the push plate 704. The moving wedge-shaped post 703 continuously moves towards the bottom of the guide plate 605, while the guide plate 605 continuously moves upwards. At this time, the upward-moving guide plate 605 can drive the limiting frame 604 upwards. When the wedge-shaped post 703... After being fully moved to the bottom of the guide plate 605, the limiting frame 604 also moves completely out from the front of the medical pack. At this time, the ejection plate 502 comes into contact with the medical pack and ejects it, so that the medical pack can be ejected directly from the inside of the storage frame 2. The above settings ensure the overall stability of the medical pack during transportation. At the same time, when ejecting the medical pack, as the ejection plate 502 moves continuously, the limiting frame 604 can automatically move upward and release the limiting of the medical pack. Moreover, the above structure can operate normally when ejecting medical packs of different sizes, thereby improving the practicality of the device.

[0044] In one embodiment, for the extrusion frame 401, a T-shaped support column 705 is fixedly connected to the top of the extrusion frame 401, the wedge-shaped column 703 is movably connected to the T-shaped support column 705, and a push spring 706 is provided on the outer side of the T-shaped support column 705.

[0045] The wedge-shaped column 703 can move continuously on the outer surface of the T-shaped support column 705 under the push of the ejector plate 502. This arrangement makes the wedge-shaped column 703 highly stable when moving. At the same time, when the ejector plate 502 is reset, the push spring 706 can push the wedge-shaped column 703, so that the wedge-shaped column 703 can be reset together with the ejector plate 502.

[0046] Through the above technical solution, 1. By driving the clamping component 3, the squeezing component 4, and the limiting component 6, the clamping end, squeezing end, and limiting end can adaptively conform to the outer surface of the medical pack; the setting of dynamic position adjustment based on the actual size of the medical pack can not only achieve precise positioning and firm fixation of medical packs of different specifications, but also form a stable guiding structure during ejection, effectively preventing the medical pack from shifting or flipping; the above settings significantly improve the adaptability of the ejection device to medical packs of multiple specifications, greatly enhancing the versatility of the equipment in diverse medical transportation scenarios; 2. When ejecting the medical pack, the moving ejection plate 502 pushes the wedge-shaped column 703 through the push plate 704, which... When the guide plate 605 is lifted by the wedge column 703, it can drive the limiting frame 604 to move upward. When the wedge column 703 has completely moved to the bottom of the guide plate 605, the limiting frame 604 also moves completely out from the front of the medical pack. At this time, the ejection plate 502 comes into contact with the medical pack and ejects it. The above configuration ensures the overall stability of the medical pack during transportation. At the same time, when ejecting the medical pack, as the ejection plate 502 moves continuously, the limiting frame 604 can automatically move upward and release the limiting of the medical pack. Moreover, the above working process can be carried out normally when ejecting medical packs of different sizes, thereby improving the practicality of the device.
