Description

Technical Field

[0001] This utility model relates to the field of electromagnetic lock technology, specifically a novel electromagnetic lock. Background Technology

[0002] Electromagnetic locks, as a security device, are widely used in various situations requiring access control, such as access control systems, safes, and car door locks. However, existing electromagnetic locks have some shortcomings that affect their efficiency and security.

[0003] Existing electromagnetic locks are cumbersome to unlock manually. Typically, users need to insert a mechanical key into the lock and turn it, then manually operate a push button or pull handle to complete the unlocking process. This operation is not only time-consuming but can also cause delays and reduce security in emergencies.

[0004] Secondly, existing electromagnetic locks are prone to overheating and have high power consumption during operation. Some electromagnetic locks even have a power consumption as high as 24W, which means they cannot operate with power on for extended periods. Furthermore, to prevent overheating, these electromagnetic locks typically require microswitches to ensure automatic power-off in case of overheating, but this limits the lock's operating time and affects its ability to work continuously.

[0005] The process of unlocking by power is also quite complicated. With power available, the user needs to manually press a microswitch first, and then manually operate the push button or pull handle to complete the unlocking. This design not only reduces the ease of operation but also increases the possibility of operational errors, thus affecting the overall performance of the electromagnetic lock and the user experience.

[0006] Therefore, based on the above-mentioned technical problems, it is necessary for those skilled in the art to develop a new type of electromagnetic lock. Utility Model Content

[0007] The purpose of this invention is to provide a novel electromagnetic lock to solve the problems mentioned in the background section.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A novel electromagnetic lock technology solution includes a housing with a viewing port. A mechanical key socket is embedded in the viewing port. A rack mounting base is provided on the back of the mechanical key socket. An unlocking rack is slidably connected to the rack mounting base. An unlocking gear is meshed with the adjacent side of the unlocking rack. An unlocking plate is connected to the tail end of the unlocking rack. A locking bolt is installed on the unlocking plate. The locking bolt is connected to the unlocking plate through a limiting nut. A locking bolt is installed at the end of the locking bolt.

[0010] As a preferred technical solution, a mechanical key is inserted into the mechanical key socket, and the end of the mechanical key engages with the unlocking gear shaft hole.

[0011] As a preferred technical solution, a cover plate is provided on the back of the housing, and a gear fixing cover plate is provided on the opposite side of the unlocking gear. The gear fixing cover plate is used for positioning the unlocking gear.

[0012] As a preferred technical solution, an electromagnet is provided outside the bolt. The electromagnet is used to attract the bolt when it is energized, thereby realizing the unlocking function of the electromagnetic lock. When the electromagnet is de-energized, the bolt is reset under the action of the spring, and the electromagnetic lock is locked.

[0013] As a preferred technical solution, the electromagnet is connected to a power supply terminal, which is located on the outside of the housing and is used to provide the electrical energy required for the electromagnet to operate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model is a novel electromagnetic lock. The visual port and mechanical key socket make it easy for users to manually unlock the lock with a mechanical key. The operation is simple and quick, greatly saving time and improving security in emergency situations.

[0016] Meanwhile, by optimizing the design of the electromagnet and the locking bolt, this utility model allows the electromagnet to remain energized for extended periods with a power of 4W, compared to 24W for traditional electromagnetic locks. Its power consumption is significantly lower than that of traditional electromagnetic locks, reducing power consumption and heat generation. This enables the electromagnetic lock to operate energized for extended periods without the need for frequent microswitches for overheat protection, thereby improving the continuous working capability of the electromagnetic lock.

[0017] Furthermore, during the unlocking process, this invention only requires controlling the energization state of the electromagnet to achieve the attraction and reset of the bolt, eliminating the need for manual operation of the push button or pull handle. This simplifies the operation steps, reduces the possibility of operational errors, and improves the overall performance and user experience of the electromagnetic lock. Attached Figure Description

[0023] The features and exemplary embodiments of various aspects of this utility model will now be described in detail. To make the objectives, technical solutions, and advantages of this utility model clearer, the following description, in conjunction with the accompanying drawings and specific embodiments, will provide a further detailed description. For those skilled in the art, this utility model can be implemented without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of this utility model by illustrating examples.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, this utility model provides a novel electromagnetic lock technical solution: including a housing 1, a viewing port 11 on the housing 1, a mechanical key socket 12 embedded in the viewing port 11, a rack mounting base 21 on the back of the mechanical key socket 12, an unlocking rack 22 slidably connected to the rack mounting base 21, an unlocking gear 23 meshing with the adjacent side of the unlocking rack 22, an unlocking plate 24 connected to the tail end of the unlocking rack 22, a locking bolt 25 installed on the unlocking plate 24, the locking bolt 25 connected to the unlocking plate 24 through a limiting nut 26, and a locking bolt 27 installed at the end of the locking bolt 25.

[0025] Among them, a mechanical key 2 is inserted into the mechanical key socket 12, and the end of the mechanical key 2 engages with the shaft hole of the unlocking gear 23.

[0026] The housing 1 has a cover plate 13 on its back, and a gear fixing cover plate 231 is provided on the opposite side of the unlocking gear 23. The gear fixing cover plate 231 is used to position the unlocking gear 23.

[0027] An electromagnet 32 ​​is installed outside the bolt 27. The electromagnet 32 ​​is used to attract the bolt 27 when it is energized, so as to realize the unlocking function of the electromagnetic lock. When the electromagnet 32 ​​is de-energized, the bolt 27 is reset under the action of the spring, and the electromagnetic lock is locked.

[0028] The electromagnet 32 ​​is connected to a power supply terminal 31, which is located on the outside of the housing 1 and is used to provide the electrical energy required for the electromagnet 32 ​​to work.

[0029] When manual unlocking is required, the user inserts the mechanical key 2 into the mechanical key socket 12 and rotates the key to drive the unlocking gear 23. The rotation of the unlocking gear 23 is transmitted to the unlocking plate 24 through the unlocking rack 22, which in turn moves the bolt screw 25, pushing the bolt 27 to move and thus unlocking the device.

[0030] When the electromagnetic lock is energized, the electromagnet 32 ​​is activated, generating a magnetic force to attract the bolt 27, keeping the bolt 27 in the unlocked position. When locking is required, the electromagnet 32 ​​is de-energized, and the bolt 27 is reset under the action of the spring force, thereby achieving locking.

[0031] Because the electromagnet 32 ​​has low power consumption (e.g., 4W), the new electromagnetic lock can operate under power for a long time without overheating, eliminating the need for frequent microswitches for overheat protection and improving the continuous working capability of the electromagnetic lock.

[0032] The design of the new electromagnetic lock's visual port 11 and mechanical key socket 12 allows users to intuitively see the lock's status and unlock it through simple mechanical key operation, improving both the convenience and security of operation.

[0033] This novel electromagnetic lock not only simplifies the operation steps and reduces the possibility of operational errors, but also improves the efficiency and security of the electromagnetic lock.
