[0060] The following embodiments of the technical solution of the present invention will be described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention.
[0061] Example:
[0062] like Figures 1 to 4 As shown, the present invention provides a pediatric drug grinding device, including a shell 101, a liftable receiving frame 301 is installed, a detachable receiving box 401 is provided in the receiving frame 301, a rotatable grinding disc 403 is provided in the receiving box 401, a mounting plate 102 is provided on the shell 101, a handle 103 and a hinged operating handle 602 are installed on the mounting plate 102, the operating handle 602 can swing along a first angle and a second angle, and a lifting mechanism is provided on the shell 101 to convert the swinging of the operating handle 602 within the first angle into driving the receiving frame 301 to rise and fall.
[0063] The lifting mechanism includes a mounting rod 303 on a receiving frame 301. The mounting rod 303 is lifted and lowered through the housing 101. A mounting shaft 601 is provided on the mounting plate 102. The mounting shaft 601 is fixedly connected to the end of an operating handle 602. The driving rod 501 is connected to the mounting shaft 601 via a connecting assembly. When the operating handle 602 swings along a first angle, the connecting assembly controls the swing of the driving rod 501. A driving column 502 is provided at the end of the driving rod 501. A sliding frame 304 is provided at the end of the mounting rod 303. The driving column 502 is slidably clamped in the sliding frame 304. The connecting assembly includes a connecting sleeve 503 provided at one end of the driving rod 501. The connecting sleeve 503 is sleeved on the end of the mounting shaft 601. One end of a torsion spring 603 is connected to the connecting sleeve 503, and the other end is connected to the mounting shaft 601.
[0064] During use, the handle 103 and the operating lever 602 can be held by hand. As the operating lever 602 swings along the first angle, the torsion of the torsion spring 603 drives the connecting sleeve 503 to rotate along with the mounting shaft 601. The rotation of the connecting sleeve 503 drives the driving rod 501 to swing. During the swinging process, the driving rod 501 drives the sliding frame 304 up and down via the driving column 502. As the sliding frame 304 rises and falls, the mounting rod 303 drives the receiving frame 301 up and down, thereby lifting the installed receiving box 401 until the receiving box 401 contacts the bottom surface of the housing 101, thereby securing the receiving box 401 in place.
[0065] like Figure 4 、 9 As shown, in this embodiment, the receiving frame 301 has multiple groups of engaging grooves 302 evenly distributed in the circumferential direction, and the receiving box 401 has multiple groups of engaging ridges 402 evenly distributed in the circumferential direction. The multiple groups of engaging ridges 402 are respectively engaged in the multiple groups of engaging grooves 302. When the receiving frame 301 is not controlled to rise, the receiving box 401 can be taken out for feeding or placing medicine. The engagement of the engaging grooves 302 and the engaging ridges 402 ensures that the receiving box 401 does not rotate relative to the receiving frame 301 after being placed in the receiving frame 301, thereby facilitating the grinding of medicine.
[0066] like Figure 1 、 5As shown in Figure 6, in this embodiment, a locking mechanism is provided on the operating handle 602, and the position of the receiving frame 301 can be locked or unlocked by the locking mechanism when the receiving frame 301 is raised or lowered. The locking mechanism includes a mounting seat 701 provided on the mounting plate 102, and a fixing pin 702 is slidably inserted into the mounting seat 701 along its axis. A stopper 703 is provided at one end of the fixing pin 702, and a locking hole 305 is provided on the mounting rod 303. One end of the wedge-shaped surface on the fixing pin 702 can be clamped into the locking hole 305, and one end of the spring 704 abuts against the mounting seat 701, and the other end abuts against the stopper 703. A driving component is also provided on the mounting shaft 601, which drives the fixing pin 702 to slide when the operating handle 602 swings within the first angle through the driving component. The driving assembly includes an arcuate ridge 604 provided on the mounting shaft 601 . The arcuate ridge 604 can abut against the stopper 703 . A guiding slope 605 is provided at one end of the arcuate ridge 604 .
[0067] After the receiving frame 301 rises to bring the receiving box 401 into contact with the housing 101, the operating handle 602 is further rotated to rotate the mounting shaft 601 and deform the torsion spring 603. During the rotation of the mounting shaft 601, the arcuate ridge 604 is moved, and the guide slope 605 at one end of the arcuate ridge 604 pushes the stopper 703 to move, causing the fixing pin 702 to slide along its axis until one end thereof is inserted into the locking hole 305. This secures the mounting rod 303 in place, preventing the receiving frame 301 from moving during the grinding process and causing the receiving box 401 to loosen, thereby improving the grinding effect. The other end of the fixing pin 702 is a wedge-shaped surface. Through the setting of the wedge-shaped surface, even if the receiving frame 301 has not fully risen to the limit position, the fixing pin 702 can be smoothly locked into the locking hole 305, avoiding the placement of medicines in the receiving box 401 and affecting the rising height of the receiving frame 301. The receiving frame 301 cannot reach the highest point and cannot be fixed in position, thereby improving the stability of the device during use.
[0068] like Figure 2 、 Figure 3 、 Figure 5 、 Figures 7 to 9As shown, in this embodiment, the operating handle 602 is further provided with a grinding mechanism. After the receiving frame 301 rises, the grinding mechanism converts the swing of the operating handle 602 within the second angle into driving the grinding disc 403 to rotate. The grinding mechanism includes a first ratchet disc 201 rotatably disposed within the housing 101. The first ratchet disc 201 is provided with a connecting post 202. The grinding disc 403 is provided with a second ratchet disc 404 that can engage with the first ratchet disc 201. A rotatably mounted connecting cylinder 104 is provided within the housing 101. The connecting post 202 is slidably disposed within the connecting cylinder 104 along its axis. An elastic member 203 is provided between the connecting cylinder 104 and the second ratchet disc 404. A transmission assembly connected to the connecting cylinder 104 is provided within the housing 101. The transmission assembly converts the swing of the operating handle 602 within the second angle into driving the connecting cylinder 104 to rotate.
[0069] The transmission assembly includes a first bevel gear 105 arranged on the connecting cylinder 104, a drive shaft 106 is rotatably arranged in the shell 101, a second bevel gear 107 and a transmission gear 108 are arranged on the drive shaft 106, the second bevel gear 107 is engaged with the first bevel gear 105, and an arc-shaped rack 606 is arranged on the operating handle 602, the arc-shaped rack 606 can pass through the mounting plate 102 and engage with the transmission gear 108.
[0070] After the locking mechanism secures the receiving frame 301, the operating handle 602 is repeatedly gripped within the second angle. This movement drives the arcuate rack 606, which in turn rotates the second bevel gear 107 through the meshing of the arcuate rack 606 and the transmission gear 108. This in turn, the meshing of the second bevel gear 107 and the first bevel gear 105 drives the connecting cylinder 104. As the connecting cylinder 104 rotates, it drives the second ratchet disc 404 to follow suit. The elastic member 203 ensures that the second ratchet disc 404 remains engaged with the first ratchet disc 201, thereby rotating the grinding disc 403 and grinding the medication. The elastic member 203 also applies downward pressure to the second ratchet disc 404, forcing the grinding disc 403 downward for thorough grinding of the medication.
[0071] like Figure 2 、 9 As shown, in this embodiment, the inner bottom surface of the receiving box 401 is provided with a first grinding pattern, and the bottom surface of the grinding disc 403 is provided with a second grinding pattern, so that the grinding of the medicine is more sufficient and delicate, and the first ratchet disc 201 can be magnetically connected to the grinding disc 403. After the grinding is completed, the operating handle 602 is swung in the opposite direction to restore it to its initial position, so that the grinding disc 403 can be separated from the receiving box 401, making it convenient to take out the receiving box 401 for feeding and cleaning.
[0072] Specific usage and beneficial effects of the present invention:
[0073] When the device is in use, the medicine to be ground can be placed in the receiving box 401, and the grinding disc 403 can be placed on the medicine. By holding the handle 103 and the operating handle 602, the operating handle 602 can be swung along the first angle to control the receiving frame 301 to rise under the action of the lifting mechanism until the receiving box 401 contacts the bottom surface of the shell 101 to fix the position of the receiving box 401. The position of the receiving frame 301 can be fixed by the locking mechanism during the rising process to avoid displacement of the receiving frame 301 during the grinding process of the medicine, which may lead to insufficient grinding.
[0074] Continue to hold the operating handle 602 so that the operating handle 602 swings within the second angle. During the swinging of the operating handle 602 within the second angle, the grinding disc 403 can be driven to rotate in the receiving box 401 by the grinding mechanism, thereby grinding the medicine. The overall operation of the device only involves placing the medicine and driving the operating handle 602 to rotate. Compared with traditional medicine grinding devices, the operation of the device is simpler and convenient to carry. It is convenient for guardians to grind children's medicines anytime and anywhere, and there is no need to power the device, so that the device can be used in various environments. The receiving box 401 is also very convenient to disassemble and assemble. After grinding, the receiving box 401 can be disassembled to take out the medicine and directly feed the medicine. It is also convenient to clean the receiving box 401 and the grinding disc 403 without complicated operations, effectively saving the time of medicine grinding.
[0075] The basic principles, main features and advantages of the present invention are shown and described above. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments.
