The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

Please refer to Figures 1 to 3, which correspond to a telescopic medicine delivery device of a preferred embodiment of the utility model, including: a base 100; an intermediate platform 200, which is telescopically arranged on the base 100; an upper platform 300, which is telescopically arranged on the intermediate platform 200; a rotating drive member 400, which is arranged on the base 100; a first transmission mechanism 500, including a rack 510 fixed on the intermediate platform 200 and a gear assembly 520 that is transmission-connected to the rotating drive member 400, the rack 510 and the gear assembly 520 being meshed; a second transmission mechanism 600, including a pulley 610 rotatably connected to the intermediate platform 200 and a synchronous belt 620 wound around the pulley 610, the length direction of the synchronous belt 620 being consistent with the length direction of the rack 510; wherein the pulley 610 is suitable for dividing the synchronous belt 620 into an upper half 621 and a lower half 622, the upper half 621 being fixedly connected to the upper platform 300, and the lower half 622 being fixedly connected to the base 100.

The utility model sets a first transmission mechanism 500 between the base 100 and the middle platform 200. The first transmission mechanism 500 is a gear rack structure with a simple structure and small space occupation, which is convenient for the base 100 and the middle platform 200 to be tightly connected. A second transmission mechanism 600 is set between the middle platform 200 and the upper platform 300. The second transmission mechanism 600 is a synchronous belt structure with low manufacturing and installation precision requirements and low cost. In addition, the upper platform 300 produces less noise during its extension and retraction process. When taking and placing medicines, the noise is not easily transmitted to the user, thereby improving the user experience.

Further, the length direction of the rack 510 is consistent with the extension direction of the middle platform 200 and/or the upper platform 300. The two ends of the rack 510 extend to both sides of the middle platform 200 in the extension direction, and when the middle platform 200 is in the retracted state, the gear assembly 520 is located in the middle of the rack 510. The rotary drive member 400 is specifically a rotary motor, and the rotary drive member 400 can drive the gear assembly 520 to rotate, thereby driving the rack 510 to move linearly along its length direction, so that the middle platform 200 fixed to the rack 510 can be extended and retracted relative to the base 100.

The base 100 is provided with a mounting structure for mounting the gear assembly 520. The gear assembly 520 includes a first gear 521 and a second gear 522 meshing with the first gear 521. The first gear 521 is fixedly connected to the output end of the rotary drive member 400. There are two second gears 522, which are arranged on both sides of the first gear 521 in the length direction of the rack 510. The second gear 522 is used to mesh with the rack 510 to drive the rack 510 to move. During the movement of the rack 510, at least one second gear 522 meshes with the rack 510. The above structure can effectively increase the moving stroke of the rack 510 and improve the telescopic range of the intermediate platform 200.

Furthermore, the upper part 621 and/or the lower part 622 are parallel to the middle layer platform 200. The synchronous belt 620 includes a receiving part 623 received between the upper part 621 and the lower part 622, and the receiving part 623 abuts against the pulley 610.

There are two groups of second transmission mechanisms 600. When the middle platform 200 is in a retracted state, the two second transmission mechanisms 600 are arranged in a centrally symmetrical manner. By setting up two groups of second transmission mechanisms 600, it can be ensured that during the extension or retraction of the middle platform 200, there is always a second transmission mechanism 600 that can reliably drive the upper platform 300 synchronously.

Further, referring to FIGS. 3 to 5 , a fixing seat 110 is fixed to the upper end surface of the base 100, and the lower half 622 of the synchronous belt 620 is fixedly connected to the fixing seat 110. The fixing seat 110 is preferably located at the end of the lower half 622. In this embodiment, there are two fixing seats 110, which correspond to the two synchronous belts 620 one by one, and the lower half 622 of the two second transmission mechanisms 600 are fixed to different fixing seats 110, respectively.

6 , the fixing seat 110 includes a fixing block 111 and a first pressing block 112 fixedly connected to the fixing block 111. The fixing block 111 is fixedly connected to the base 100. The fixing block 111 is recessed inward from its upper end surface to form a mounting groove 1111. The mounting groove 1111 is formed through the length direction of the synchronous belt 620. The synchronous belt 620 is adapted to the mounting groove 1111. The first pressing block 112 covers the notch of the mounting groove 1111 and is tightly pressed against the lower half 622.

The first pressing block 112 includes a first pressing surface 1121 facing the tooth surface of the lower portion 622 of the synchronous belt 620 . The first pressing surface 1121 is preferably a tooth surface structure, and the first pressing surface 1121 is meshed with the tooth surface of the lower portion 622 .

Further, referring to Fig. 4, Fig. 5 and Fig. 7, the middle layer platform 200 is provided with a mounting portion 210 in the vertical direction, the mounting portion 210 is a slot or a hole, the mounting portion 210 corresponds to the pulley 610 one by one, the two pulleys 610 are rotatably placed in different mounting portions 210, and the top of the pulley 610 protrudes from the upper end surface of the middle layer platform 200, and the bottom of the pulley 610 protrudes from the lower end surface of the middle layer platform 200. The upper half 621 of the synchronous belt 620 is located above the middle layer platform 200, and the lower half 622 is located below the middle layer platform 200, so that the synchronous belt 620 is connected to the base 100 and the upper platform 300.

Furthermore, the lower end surface of the upper platform 300 is fixed with a second pressing block 310, and the upper half 621 is fastened between the lower end surface of the upper platform 300 and the second pressing block 310. Preferably, the second pressing block 310 is located at the end of the upper half 621 to increase the movement stroke of the upper platform 300.

The second pressing block 310 includes a second pressing surface 311 facing the tooth surface of the upper part 621 of the synchronous belt 620. The second pressing surface 311 is also a tooth surface structure and meshes with the tooth surface of the upper part 621, so that it can be tightly connected with the upper part 621 to ensure that the upper platform 300 can reliably move synchronously with the upper part 621.

Further, as shown in FIG. 1 , the upper platform 300 is used to carry a turnover box (not shown), and the upper platform is provided with limit blocks 320 on both sides of the conveying direction to limit the movement of the turnover box in the telescopic direction. In order to facilitate the telescopic medicine delivery device to load and unload and reliably transfer the turnover box containing medicines, it also includes a guide plate 700 fixed on the base 100, the number of the guide plates 700 is two, and they are relatively arranged on both sides of the base 100, and the middle platform 200 and the upper platform 300 are located between the two guide plates 700 to limit the turnover box in the horizontal direction perpendicular to the telescopic direction. A detection sensor 810 is fixed on one of the guide plates 700, and the detection sensor 810 is arranged on both sides of the guide plate 700 in the telescopic direction, so that when the middle platform 200 and the upper platform 300 are telescoped relative to the base 100 in different directions, one of the detection sensors 810 detects the turnover box on the upper platform 300, and then determines the telescopic state. In this embodiment, two detection sensors 810 are arranged on each side of the guide plate 700, which are the first sensor and the second sensor respectively. The first sensor is closer to the side of the guide plate 700 than the second sensor. The detection direction of the first sensor is the horizontal direction perpendicular to the telescopic direction, and the detection direction of the second sensor is the horizontal direction inclined toward the extension direction. When the medicine delivery device is in the retracted state and the turnover box is placed on the upper platform, the first sensor and the second sensor cannot detect the turnover box, and when the middle platform 200 and the upper platform 300 are extended, the second sensor can first detect the turnover box, and due to its inclined arrangement, its detection range is wide, until the middle platform 200 and the upper platform 300 are fully extended, the second sensor can always detect the turnover box; and the setting of the first sensor can cooperate with the second sensor to determine the position of the turnover box, that is, the turnover box is about to enter or leave the base 100, so as to reliably obtain the status information of the medicine delivery device, which is convenient for cooperation and coordination.

In addition, a barcode scanner 820 is also provided on the guide plate 700, and the second sensor is located between the first sensor and the barcode scanner 820. The barcode scanner 820 is also oriented in a horizontal direction inclined toward the extension direction, so that the information code on the turnover box can be easily scanned and identified. At the same time, the first sensor can coordinate with the barcode scanner 820. When the first sensor identifies the turnover box, the barcode scanner 820 will be turned on to avoid the barcode scanner 820 being always in the open state. There are two barcode scanners 820, which are respectively located on both sides of the guide plate 700. The detection sensors 810 and barcode scanners 820 on both sides of the guide plate 700 are arranged symmetrically.

Preferably, the guide plate 700 is provided with a mounting opening 710 in the horizontal direction of the vertical telescopic direction, and the detection sensor 810 and the code scanner 820 are both located in the mounting opening 710, so that the detection sensor 810 and the code scanner 820 can be protected in the vertical direction to avoid loss. Preferably, the guide plate 700 is provided with an adjustment waist hole 720 extending through the mounting opening 710 in the vertical direction at the mounting opening 710, and the length direction of the adjustment waist hole 720 is consistent with the telescopic direction, and the second sensor and the code scanner 820 are provided with a bracket 830, and the bracket 830 is provided with a circular hole (not shown) corresponding to the adjustment waist hole 720, and the circular hole and the adjustment waist hole 720 are connected by a fastener (not shown). With the above structure, the position and inclination angle of the second sensor and the code scanner 820 in the telescopic direction can be flexibly adjusted, so that the second sensor and the code scanner 820 can be adapted to different turnover boxes and telescopic strokes.

The working process of the telescopic medicine delivery device of the utility model is as follows: the rotating driving member 400 drives the first gear 521 to rotate, and drives the second gear 522 to rotate, and the rack 510 moves along its length direction under the meshing action of the second gear 522, so that the middle layer platform 200 can be telescoped relative to the base 100; during the movement of the middle layer platform 200, the pulley 610 moves synchronously with it, and then pushes the receiving part 623 toward the synchronous belt 620 in the moving direction of the middle layer platform 200, and makes the upper part 621 of the synchronous belt 620 It moves along the moving direction of the middle platform 200 and gradually turns to the lower part 622; and when the upper platform 300 moves, it will pull the receiving part 623 of the synchronous belt 620 away from the moving direction of the middle platform 200, so that the upper part 621 of the synchronous belt 620 moves along the moving direction of the middle platform 200, and gradually turns the lower part 622 to the upper part 621, thereby ensuring that when the rotating drive part 400 rotates clockwise or counterclockwise, the upper platform 300 can always be effectively driven to move.

The above description is only an implementation method of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the description and drawings of this application, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present application.
