Abstract
Description
Technical Field
[0001] This utility model belongs to the field of medical device technology, specifically relating to a medicine cabinet equipped with an electromechanical dual control system. Background Technology
[0002] "Drug, narcotic, and psychotropic drug cabinets" refer to specialized storage cabinets used for storing drugs, narcotic drugs, and psychotropic substances. They are commonly found in medical institutions, pharmacies, laboratories, and other similar locations. These drugs are strictly controlled special drugs and are managed using a "double-person, double-lock" system. Their storage and management must comply with relevant national laws and regulations to ensure safety and prevent misuse or loss.
[0003] For ease of management, medicine boxes need to be locked. And nowadays, most are electronic locks, which provides convenience for managing special medicines.
[0004] However, electronic locks sometimes fail due to malfunctions, insufficient power, or other reasons. Therefore, a medicine cabinet with an emergency mechanical lock control system is needed. At the same time, this emergency mechanical lock control system must also meet the requirements of "two people, two locks" management. Utility Model Content
[0005] The technical problem this invention aims to solve is: how to design a medicine cabinet with a mechanical locking system to meet the management requirements of "two people, two locks".
[0006] The specific technical solution of this utility model is as follows:
[0007] A medicine cabinet equipped with a dual electromechanical control system includes a cabinet body with multiple drawers arranged vertically on the cabinet body.
[0008] The drawer has a fixed locking plate with locking holes. The cabinet has multiple locking levers, the number of which matches the number of drawers. The locking levers are rotatably connected to the cabinet via a rotating part. Each locking lever has a latch plate; when the latch plate is inserted into the locking hole, the drawer is locked. The cabinet has a vertical bar that slides up and down along the cabinet. Multiple levers are fixed to the vertical bar, positioned below and in contact with the locking levers. The upper end of each lever is a curved section. The cabinet has a primary lock and a secondary lock. The primary lock includes a primary lock cylinder, which is connected to a primary lock disc. A primary lock lever is fixed to the primary lock disc, positioned below and in contact with the curved section. The side of the primary lock disc closest to the secondary lock is the locking surface. The secondary lock includes a secondary lock cylinder, which is connected to a secondary lock disc. A secondary lock abutment is fixed to the secondary lock disc, with its outer end contacting the locking surface.
[0009] The cabinet is fixed with multiple limit posts, and the vertical strips are provided with multiple limit strip holes that cooperate with the limit posts. The limit posts are located inside the limit strip holes.
[0010] The cabinet is fixed with an arc-shaped hole, and a locking rod is fitted with a slider that fits into the arc-shaped hole. The slider is located inside the arc-shaped hole and can slide within it.
[0011] The locking plate is located above the locking tongue plate. The locking rod fixes the counterweight, which is located on the opposite side of the locking tongue plate, so that the gravitational torque on the side of the locking tongue plate is less than the gravitational torque on the side of the counterweight.
[0012] The locking plate, locking rod, and vertical bars are all located on the back of the medicine cabinet.
[0013] Compared with the prior art, the technical effect of this utility model is that the medicine cabinet with a unique mechanical lock control system can lock the primary lock cylinder with a secondary lock, which meets the management requirements of "two people, two locks" and makes it convenient for medical staff to use.

[0024] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.
[0025] like Figure 1-2A medicine cabinet equipped with a dual electromechanical control system includes a cabinet body (also an outer shell) 100, on which multiple drawers 200 are arranged vertically. The number of drawers 200 is determined according to actual needs; five are shown in the figure.
[0026] like Figure 3 The drawer 200 has a fixed locking plate 210, and the locking plate 210 has a locking hole 211.
[0027] like Figure 3-5 The cabinet 100 is equipped with multiple locking rods 300, the number of which is the same as the number of drawers 200. Each locking rod 300 controls one drawer 200. The locking rods 300 are rotatably connected to the cabinet 100 via rotating parts 310. The locking rods 300 are equipped with locking tongue plates 350. When the locking tongue plates 350 are inserted into the locking cavity holes 211, the drawers 200 are locked.
[0028] In the prior art, the rotating part 310 is connected to the output shaft of the motor, and the rotation of the motor is controlled by an electronic / software control system to achieve "dual-person dual-lock" management.
[0029] The problem this application aims to solve is the failure of the electronic / software control system.
[0030] like Figure 3-8 The cabinet 100 is provided with a vertical bar 400, which can slide up and down along the cabinet 100. Multiple levers 420 are fixed on the vertical bar 400. The levers 420 are located below and in contact with the locking lever 300. The upper end of the lever 420 is a curved part 470.
[0031] like Figure 8-10 The cabinet 100 is equipped with a primary lock and a secondary lock. The primary lock includes a primary lock cylinder 480, which is keyed to a primary lock disc 481. A primary lock lever 482 is fixed on the primary lock disc 481. The primary lock lever 482 is located below and in contact with the curved part 470. The side of the primary lock disc 481 near the secondary lock is a locking plane 483.
[0032] like Figure 8-10 The secondary lock includes a secondary lock cylinder 490, which is keyed to a secondary lock disc 493. A secondary lock abutment block 491 is fixed on the secondary lock disc 493, and the outer end 492 of the secondary lock abutment block 491 contacts the locking plane 483.
[0033] like Figure 7To facilitate the vertical bar 400 to slide up and down along the cabinet 100, the cabinet 100 is fixed with multiple limiting posts 120. The vertical bar 400 is provided with multiple limiting strip holes 410 that cooperate with the limiting posts 120. The limiting posts 120 are located in the limiting strip holes 410. By moving the position of the limiting posts 120 within the limiting strip holes 410, the vertical bar 400 can slide up and down along the cabinet 100.
[0034] like Figure 6 To facilitate the rotation range of the locking rod 300, the cabinet 100 has a fixed arc-shaped hole 110. A slider 320, which mates with the locking rod 300 within the arc-shaped hole 110, is positioned within and can slide within it. The movement of the slider 320 within the arc-shaped hole 110 allows the locking rod 300 to rotate along the rotating part 310. The length of the arc-shaped hole 110 controls the rotation range of the locking rod 300.
[0035] As shown in the figure, in order to facilitate reset, the locking cavity plate 210 is located above the locking tongue plate 350, and the locking rod 300 fixes the counterweight 360. The counterweight 360 is located on the opposite side of the locking tongue plate 350, so that the gravitational torque on the side of the locking tongue plate 350 is less than the gravitational torque on the side of the counterweight 360.
[0036] For aesthetic purposes, the locking plate 210, locking rod 300, and vertical bar 400 are all located on the back of the medicine cabinet.
[0037] For easy movement, the medicine cabinet is equipped with four 180-degree wheels on its bottom. These wheels can be either swivel casters or drive wheels, depending on the specific needs.
[0038] Its working principle is as follows:
[0039] The existing technology of controlling the rotation of the motor and whether the lock tongue plate 350 is inserted into the lock cavity hole 211 through the electronic / software control system to achieve "double person double lock" management is not described in detail here.
[0040] The mechanical "double-person, double-lock" management system will now be explained in detail.
[0041] I. Locking
[0042] S11, such as Figure 3 The lock cylinder 480 is in the locked state, the curved part 470 is in the low position, the vertical bar 400 is also in the low position, the locking rod 300 on the side of the counterweight 360 is also in the low position, the locking rod 300 on the side of the latch plate 350 is in the high position, the latch plate 350 is inserted into the lock cavity hole 211, and the drawer 200 is in the locked state.
[0043] S12, such as Figure 8When the outer end 492 of the secondary locking block 491 contacts the locking plane 483, it can prevent the primary locking disc 481 from rotating clockwise, thus locking the primary lock.
[0044] S13. Remove the key from the secondary lock cylinder 490, and the secondary lock is locked.
[0045] II. Unlock
[0046] S21, such as Figure 8-10 Insert the key into the secondary lock cylinder 490 and turn the secondary lock cylinder 490 clockwise to unlock the secondary lock; simultaneously, the secondary lock abutment block 491 also rotates clockwise. (See below) Figure 10 The middle arrow indicates that the outer end 492 of the secondary locking block 491 is away from the locking plane 483, and the primary lock is in an unlockable state.
[0047] S22. Insert the key into the primary lock cylinder 480 and turn the primary lock cylinder 480 clockwise to unlock the primary lock.
[0048] S23. During the rotation of the lock cylinder 480, the lock lever 482 moves the bent part 470 upward, the vertical bar 400 slides upward along the cabinet body 100, the lever 420 moves upward in sync, the lever 420 moves the locking bar 300 to rotate counterclockwise along the rotating part 310, the lock tongue plate 350 leaves the lock cavity hole 211, and the drawer 200 is in the unlocked state.
[0049] In this way, the mechanical locking mechanism can also control whether the lock tongue plate 350 is inserted into the lock cavity hole 211, thereby realizing the management of "two people and two locks".
[0050] Features of this application:
[0051] S1. This application has two locking mechanisms:
[0052] There are mechanical locking mechanisms and electronic / software control systems that control the motor's locking mechanism. However, the two do not interfere with each other and can be used independently.
[0053] During the operation of the aforementioned mechanical locking mechanism, the locking mechanism of the motor controlled by the electronic / software control system cannot affect it; similarly, the aforementioned mechanical locking mechanism does not interfere with the locking mechanism of the motor controlled by the electronic / software control system.
[0054] S2. Regarding the reset of the mechanical locking mechanism:
[0055] The locking rod 300 is reset by the gravitational torque of the counterweight 360; the vertical bar 400 is reset by its own gravity.
[0056] It should be noted that in the locking mechanism of the motor controlled by the electronic / software control system, each locking lever 300 can be controlled individually; in the mechanical locking mechanism, one vertical bar 400 can control all the locking levers 300.
[0057] For other details, please refer to the existing technology.
[0058] The above description is only a preferred embodiment of the present utility model. It should be noted that those skilled in the art can make several changes and improvements without departing from the overall concept of the present utility model, and these should also be considered within the protection scope of the present utility model.
