[0019] The specific embodiments of this application will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this application, but are not intended to limit the scope of this application.
[0020] like Figure 1 As shown in the preferred embodiment of this application, a door lock device 10 includes a double door 20 comprising a main door 201 and a secondary door 202. The door lock device 10 is installed on the main door 201 and includes a guide shell 101, a turntable 102, an upper door latch 103, a lower door latch 104, and a rotating handle 105.
[0021] The guide shell 101 is fixedly connected to the main door 201, the guide shell 101 is provided with an upper guide slot 1011 and a lower guide slot 1012, the rotating disc 102 is rotatably connected to the guide shell 101, the upper door latch rod 103 slides in the upper guide slot 1011, the lower door latch rod 104 slides in the lower guide slot 1012, the bottom of the upper door latch rod 103 is rotatably connected to the first hole 1021 on the rotating disc 102, the top of the lower door latch rod 104 is rotatably connected to the second hole 1022 on the rotating disc 102, the first hole 1021 and the second hole 1022 are symmetrically distributed on the rotating disc 102, and the first end of the rotating handle 105 is fixedly connected to the rotating disc 102.
[0022] When the tail end of the rotating handle 105 is forced to swing, the rotating disc 102 is driven to rotate, the upper door latch rod 103 is driven to be inserted into the first fixed hole, and the lower door latch rod 104 is driven to be inserted into the second fixed hole, the first fixed hole is provided on the door frame above the main door 201, and the second fixed hole is provided on the door frame below the main door 201.
[0023] Through the above scheme, the rotating force of the rotating handle 105 is converted into the linear motion force of the two door latch rods, and the two door latches are simultaneously driven to fix the double-leaf door 20. Compared with the simple buckle scheme, the stability of locking is increased, the design of the two door latches can better fit the door frame, the size of the door gap is reduced, and the sealing performance is improved. Moreover, since the two door latches are simultaneously actuated, the user only needs to operate one rotating handle 105 to complete the locking of the entire door, thereby greatly improving the work efficiency.
[0024] It can be understood that the door lock device 10 of the present application can be installed on any storage and transportation equipment with a double-leaf door 20, such as a transfer vehicle, a file cabinet, a medicine cabinet, etc., without affecting the implementation of the present application scheme, and the scheme installed on other storage and transportation equipment should also fall within the protection scope of the present application.
[0025] In order to increase the security performance, as shown in Figure 2 The rotating handle 105 can also be provided with a limiting hole 1051, and the door lock device 10 further comprises a plastic buckle 106, the plastic buckle 106 passes through the limiting hole 1051 and is fixed on the main door 201.
[0026] By adding the limiting hole 1051, the rotation of the rotating handle 105 can be limited, so that the probability of jolting opening of the door lock device 10 in the present application during running can be reduced.
[0027] This design provides higher security and confidentiality protection for the transportation of sterile medical devices. In actual application, after loading the sterile goods and devices, the staff can firmly pass the plastic buckle 106 through the limiting hole 1051 and fix it on the main door 201, ensuring that the door lock device 10 will not be accidentally opened. When it is necessary to open the storage and transportation equipment, the plastic buckle 106 must be removed first, which will leave obvious traces, further enhancing the monitoring and traceability of the goods transportation process.
[0028] In addition, the material of the plastic buckle 106 can be selected to have certain strength and toughness, which can withstand the bumps and vibrations during transportation, and is not easy to be easily damaged or forged. Special marks or codes can be set on the plastic buckle 106 to facilitate the identification and management of different storage and transportation equipment. In this way, throughout the entire logistics chain, whether it is the transportation personnel, warehouse management personnel or the final user, they can judge the confidentiality and integrity of the storage and transportation equipment by checking the status of the plastic buckle 106.
[0029] For some sterile medical devices with extremely high confidentiality requirements, electronic tags or sensors can also be integrated on the plastic buckle 106. For example, electronic tags using radio frequency identification (RFID) technology can communicate with reading devices through wireless signals to monitor the status and position of the plastic buckle 106 in real time. If the plastic buckle 106 is illegally removed or damaged, the system can immediately issue an alarm to remind relevant personnel to take measures. The sensor can detect environmental parameters such as temperature and humidity to ensure that the sterile goods and devices are transported and stored in a suitable environment.
[0030] In summary, by setting the limiting hole 1051 on the rotary handle 105 and cooperating with the use of the plastic buckle 106, the door lock device 10 of the present application not only increases the confidentiality feature, but also improves the safety and reliability of the transportation of sterile medical devices, providing an effective solution for the logistics management of the medical industry.
[0031] On the basis of any of the above embodiments, in another embodiment of the present application, the limiting hole 1051 can be provided at the tail end of the rotary handle 105. By setting the limiting hole 1051 at the head end of the rotary handle 105, the limiting hole 1051 acts as a fulcrum, which is equivalent to increasing the moment of the tail end of the rotary handle 105 to the fulcrum. Therefore, when it is necessary to open the door lock device 10, the plastic buckle 106 can be disconnected more quickly and labor-saving to open the door lock device 10.
[0032] In an embodiment of the present application, as shown in Figure 3 The plastic buckle 106 can be provided with a mounting surface 1061 on which a label is attached.
[0033] The label attached to the plastic buckle 106 is used to mark the information of the current item or the relevant information of the responsible person. Through the label, it can be quickly judged whether the storage and transportation equipment is the equipment that needs to be opened, which is convenient for inquiry and traceability. At the same time, the existence of the label also makes the items more easily managed and monitored during the entire transportation and storage process.
[0034] When it is necessary to track a specific item, the staff can quickly obtain the detailed information of the item, including the production date, validity period, production batch, transportation route, etc. by scanning the two-dimensional code or barcode on the label. This not only improves work efficiency, but also greatly reduces the possibility of errors.
[0035] In addition, the material of the label usually has the characteristics of waterproof, moisture-proof, wear-resistant, etc. to ensure that it can remain clear and readable in various harsh environments. Even after a long period of transportation and storage, the information on the label will not be easily damaged or lost.
[0036] For the responsible person, the information on the label can clearly define his responsibility for the item. Once a problem occurs, the relevant responsible person can be quickly found to investigate and handle the problem. This helps to improve the responsibility and rigor of the work, and ensures the safe transportation and storage of sterile medical devices.
[0037] In another embodiment of the present application, the height of the connection between the plastic buckle 106 and the main door 201 is lower than the height of the turntable 102, so that when the plastic buckle 106 passes through the limiting hole 1051 and is fixed on the main door 201, the tail end of the rotating handle 105 points to the ground.
[0038] The design of the connection between the plastic buckle 106 and the main door 201 being lower than the height of the turntable 102 makes the tail end of the rotating handle 105 point to the ground when the plastic buckle 106 is fixed on the main door 201. In this state, the rotating handle 105 will not be affected by gravity to continue to move downward, so that during transportation, even if it is impacted or jolted by external force, the rotating handle 105 is not easily accidentally touched, thereby reducing the risk of accidental opening of the door lock device 10, greatly improving the safety of sterile medical device transportation.
[0039] In any of the above embodiments, a prominent color mark can be provided on the plastic buckle 106. For example, red indicates that the equipment is in a locked state and cannot be opened without authorization, yellow indicates that the equipment needs special treatment or inspection, and green indicates that the equipment can be normally opened.
[0040] Different colored plastic buckles 106 can help staff quickly distinguish between different types of storage and transportation equipment or different states of equipment, improving work efficiency and accuracy.
[0041] In another embodiment of the present application, the first holes 1021 are distributed on one side of the rotating disc 102 close to the secondary door 202, and the second holes 1022 are arranged on the other side of the rotating disc 102 away from the secondary door 202.
[0042] Through the above scheme, since the first holes 1021 connected by the upper door latch rod 103 are distributed on one side of the rotating disc 102 close to the secondary door 202, the tail end of the rotating handle 105 is moved from the top to the bottom when the door is opened and closed. Therefore, when the door locking device is closed, the rotating handle 105 is always in a low position, and at this time, the gravity of the rotating handle 105 itself plays an important role. The gravity makes the rotating handle 105 have a downward pulling force, and this pulling force is transmitted to the door latch through the rotating disc 102 and the door latch rod, so that the door locking device 10 becomes tighter and tighter. Even if the door locking device 10 is subjected to jolting during transportation, it is difficult to be jolted apart due to the continuous action of gravity.
[0043] In an embodiment of the present application, the rotating handle 105 is arranged downward from the head end to the tail end, and is first bent downward and then upward from the head end to the tail end. In this way, the distance between the tail end of the rotating handle 105 and the main door 201 is greater than the distance between the head end of the rotating handle 105 and the main door 201.
[0044] When the operator needs to rotate the rotating handle 105 to lock or unlock the door, the Z-shaped structure provides sufficient space for the hand to move freely and is not hindered by the door, so that the operation can be completed more easily and the work efficiency is improved.
[0045] In an embodiment of the present application, the door locking device 10 is installed on the main door 201 by a rivet.
[0046] The rivet is used to install the door locking device 10 on the main door 201, which has the following advantages: the rivet connection method has high strength and stability, and is difficult to loosen or break under long-term vibration compared with the ordinary bolt connection method. The rivet fixing method can effectively reduce the situation of missing parts during jolting, and once the rivet is installed, it is difficult to fall off or lose by itself.
[0047] Since the door locking device 10 fixed by the rivet has high stability and reliability, the maintenance cost can be reduced. Compared with other connection methods, the rivet connection does not need to be checked and maintained frequently, which reduces the labor and material costs.
[0048] In summary, the embodiments of the present application provide a door locking device 10 which enhances the sealing performance by simultaneously operating multiple door latches. In some embodiments, the self-gravity is further utilized to reinforce the locking effect. In some other embodiments, a certain security effect can be further increased.
[0049] The above merely describes the preferred embodiments of the present application, and it should be pointed out that, for those skilled in the art, some improvements and replacements can be made without departing from the technical principles of the present application, and these improvements and replacements should also be considered as the protection scope of the present application.
