[0034] Embodiment 2:

[0035] Reference Figure 1-Figure 7 , a locking component, including a health all-in-one machine body, the health all-in-one machine body is an intelligent device that integrates multiple health detection functions. It usually includes the function of measuring multiple physiological indicators such as weight, body fat content, blood pressure, heart rate, blood oxygen saturation, etc. By using the health all-in-one machine, users can monitor their health status conveniently and quickly, understand the changes in various physical indicators, and thus adjust their lifestyle and health management methods in time. This is a prior art. A storage bin 1 is also provided on the health all-in-one machine, and a storage box is also installed in the storage bin 1, where medical supplies such as band-aids, gauze, sterilized cotton balls, medical tape, etc. can be placed for the elderly to facilitate first aid and treatment of small wounds. A limited block is fixedly connected in the storage bin 1, and a slidable drawer body 2 is also installed in the storage bin 1, and a storage box is fixedly connected in the drawer body 2. A limited plate is also fixedly connected at the bottom of the drawer body 2, and then the limit plate is slidably connected to the limit block for sliding it, so as to slide the drawer body 2.

[0036] In addition, please refer to Figure 4-Figure 6A stretching groove 201 is also provided at the bottom of the drawer body 2, and a first connecting shaft 4 is fixedly connected to the drawer body 2, and then the pressing plate 3 is rotatably connected to the first connecting shaft 4, and a button made of rubber or silicone is fixedly connected to the bottom of the pressing plate 3, and a lower pressing plate 301 is vertically arranged at the other end of the pressing plate 3, and a first spring 401 is fixedly connected to the side of the lower pressing plate 3 facing the pressing plate 3, and then the other end of the first spring 401 is fixedly connected to the drawer body 2, so that it can press the lower pressing plate 301 The limit line ensures that it can be fixedly connected to the drawer body 2 without shaking. At the same time, a second connecting shaft 6 is fixedly connected to the drawer body 2, and a toggle plate 5 is rotatably connected to the second connecting shaft 6, and one end of the toggle plate 5 is against the bottom end of the lower pressure plate 301, and a card plate 7 is fixedly connected to the other end of the toggle plate 5, and a second spring 601 is fixedly connected to the upper end surface of the card plate 7. One of the purposes is to make the other end of the toggle plate 5 always against the bottom end of the lower pressure plate 301, so that the pressing plate 3 and the card plate 7 are in a linkage state.

[0037] Also, please refer to Figure 5 and Figure 6 An inclined surface 701 is provided at the contact end of the card plate 7, a guide plate 102 is fixedly connected in the storage bin 1, and the guide plate 102 has the same inclination angle as the inclined surface 701, a card slot 101 is provided in the storage bin 1, the guide plate 102 is provided at the outer end portion of the card slot 101, and the guiding position direction of the guide plate 102 is toward the card slot 101.

[0038] The working principle is as follows: when the drawer body 2 on the health all-in-one machine body needs to be pulled out, the drawer body 2 is in a locked state to prevent children from taking out the items in the drawer body 2; when an adult needs to use the items inside, he can use his finger to press the button at the bottom of the pressing plate 3, and at this time, under the influence of the first connecting shaft 4, the pressing plate 3 will rotate, and the contact end at the bottom of the lower pressing plate 301 will rotate synchronously, thereby pressing down the position of the toggle plate 5, and in this process, the first spring 401 will be compressed and accumulate force, and the toggle plate 5 will be pressed down. The movable plate 5 will be affected by the second connecting shaft 6, driving the card plate 7 to rotate upward, and then moving the card plate 7 to the outside of the card slot 101. At the same time, the second spring 601 will also be compressed and accumulate force, and then the card plate 7 will be freed from the restraint of the card slot 101. At this time, the drawer body 2 is pulled out again, and then automatic unlocking can be achieved to prevent the card plate 7 from being stuck in the card slot 101. Then the finger stops pressing the button at the bottom of the pressing plate 3. At this time, the first spring 401 and the second spring 601 will automatically open outward, and the pressing plate 3 will automatically reset.

[0039] In addition, when the drawer body 2 needs to be locked, the drawer body 2 can be inserted into the storage bin 1. During this process, the guide plate 102 arranged in the storage bin 1 will cooperate with the card plate 7. At this time, the inclined surface on the guide plate 102 fits with the inclined surface at the bottom end of the card plate 7, so as to guide the card plate 7. During this process, the second spring 601 will be compressed and accumulate force, and the toggle plate 5 will be affected by the second connecting shaft 6, and the toggle plate 5 will automatically rotate downward. Then, when the card plate 7 moves into the card slot 101, the second spring 601 will open outward to apply pressure to the card plate 7. The card plate 7 can then be firmly locked in the card slot 101 in the storage bin 1. By self-locking the drawer body 2, it can effectively prevent children or pets from accidentally opening the drawer and ingesting or misusing the medicine inside, thereby preventing accidental poisoning or adverse reactions, thereby improving the safety of the device. At the same time, the drawer body 2 can be unlocked to allow the elderly to open the drawer more conveniently without the need for additional keys or unlocking steps, thereby improving the convenience of use. In addition, by arranging a stretching slot 201 at the bottom of the drawer body 2, it can also prevent children from observing the unlocking position, thereby improving the practicality of the device.

[0040] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
