Description

Technical Field

[0001] The utility model relates to the technical field of electronic safety locks, in particular to a low-power electronic safety lock used in industrial sites. Background Art

[0002] Electronic locks have been widely used in many fields. Compared with traditional mechanical locks, they have the advantage of being more resistant to technical unlocking. Electronic locks control the operation of circuits or chips through password input, and then control the closing operation of mechanical switches to complete the opening and closing tasks of electronic products. Compared with traditional mechanical password locks, electronic locks overcome the shortcomings of mechanical password locks with few passwords and poor security performance, greatly improving the password locks in both technology and performance.

[0003] The application number is CN202120242557.1, which is a low-power electronic safety lock for industrial sites. By setting a fixed frame and a cover plate, the fixed frame and the cover plate are fixedly installed on the outside of the electronic lock, so that the electronic lock is separated from the external environment, and the electronic lock is prevented from being affected by the external environment, and at the same time, the electronic lock is prevented from being collided. By setting a sealing ring, the sealing ring prevents dust and moisture from entering the interior of the fixed frame from the connection between the fixed frame and the cover plate. By setting a drying device, the drying device absorbs the moisture entering the interior of the fixed frame, so that the interior of the fixed frame remains dry, and the electronic lock is prevented from being damaged by moisture, thereby better protecting the electronic lock. However, when the application device is used in practice, the cover plate needs to be opened, and after opening the electronic lock, the cover plate needs to be closed again. When the staff is in use, they will forget to close the cover plate, resulting in the electronic lock being unable to continue to be protected. Therefore, a low-power electronic safety lock for industrial sites that can automatically open and close the cover plate is needed. Utility Model Content

[0024] When the utility model is further implemented, by pressing the start button 8, the mobile power assembly 6 is started and drives the moving block 5 to move horizontally, so that the frame cover 4 slides on the horizontal slide groove 301. Since the control box 7 is equipped with components such as a controller, a timer, and a relay, after the motor of the mobile power assembly 6 rotates forward for a certain period of time, the timer will send a stop signal. After receiving the signal, the controller controls the current motor to stop running. At this time, the protection frame 3 is opened, as shown in the attached figure. Figure 1 , the electronic lock 2 can be opened. After a period of time, the timer sends a start signal. After receiving the signal, the controller controls the current motor to reverse until a period of time later, the frame cover 4 moves to the protection frame 3 and closes, thereby realizing automatic opening and closing of the frame cover 4, which is easy to use and prevents workers from forgetting to close the frame cover 4.

[0025] Combined with Figure 3 The surface of the electronic lock 2 is provided with a fingerprint unlocking interface 9, a password unlocking interface 10, and a handle 11 in sequence from top to bottom.

[0026] Combined with Figure 4 , the frame cover 4 is vertically provided with a horizontal connecting plate 401 slidably connected to the upper and lower end surfaces of the protection frame 3, and the inner side of the end of the horizontal connecting plate 401 is provided with a sliding plate 402 slidably connected to the horizontal slide groove 301.

[0027] Combined with Figure 4 The moving block 5 includes a connecting plate 501 installed at the upper end of the frame cover 4, and a moving block 2 502 connected to the moving power assembly 6 is provided at one end of the connecting plate 501 away from the sliding plate 402.

[0028] Combined with Figure 3 The mobile power assembly 6 includes a pair of support plates 13 installed on the left and right sides of the upper end of the protection frame 3, a threaded rod 14 is connected to the bearing between the pair of support plates 13, and a motor 15 connected to the threaded rod 14 is installed at the right end of the right support plate 13, and the threaded rod 14 passes through the moving block 2 502 and is threadedly connected thereto.

[0029] When the mobile power assembly 6 is in use, the motor 15 drives the threaded rod 14 to rotate, so that the moving block 2 502 threadedly connected to the threaded rod 14 moves left and right, thereby moving the frame cover 4 left and right, so that the protection frame 3 is automatically opened and closed.

[0030] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
