Description

Technical Field

[0001] This utility model relates to the field of unlocking device technology; more specifically, it relates to an electromagnetic unlocking device for a locking mechanism. Background Technology

[0002] As a basic safety and fixing component, locking mechanisms are widely used in various industrial equipment, enclosures, security doors, transportation devices, and special containers. Their core function is to mechanically restrict the movement of the locked parts, ensuring the stability and safety of the equipment during transportation, operation, or non-operation.

[0003] To achieve remote or controllable release of locking mechanisms, electromagnetic unlocking devices have become a mainstream solution. Traditional electromagnetic unlocking devices are usually fixedly installed, that is, the electromagnet is directly integrated as the actuator into or near the locking mechanism body. When energized, the magnetic force generated by the electromagnet directly or through the transmission mechanism drives the locking pin to move, overcoming the spring preload and thus unlocking. This fixed design has the advantages of compact structure and rapid response, and is suitable for single equipment and scenarios where the electromagnet is installed in a fixed position.

[0004] Currently, while existing electromagnetic unlocking devices offer good performance, most employ fixed installation methods, integrating them within or near the locking mechanism. In large systems with multiple identical or similar locking mechanisms, each locking point requires an independent electromagnet and corresponding wiring and control circuitry. This significantly increases system costs, wiring complexity, and maintenance workload. Furthermore, in emergencies such as mains power outages or control system failures, the fixed-power electromagnetic unlocking device will malfunction, posing a safety risk. Although uninterruptible power supplies (UPS) can be provided, this further increases system complexity and cost, thus reducing the device's practicality and convenience. After use, the device is often stored haphazardly, typically placed directly in toolboxes or tool rooms alongside other tools without effective dedicated protection. This storage method makes it highly susceptible to damage from collisions and scratches between tools, potentially harming the device's delicate electromagnetic interfaces or mechanical structures, affecting its reliability and accuracy for future use, and further reducing its usability. Therefore, there is an urgent need for an electromagnetic unlocking device for locking mechanisms to address these issues. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an electromagnetic unlocking device for a locking mechanism to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: an electromagnetic unlocking device for a locking mechanism, comprising: The base plate and the protective plate are provided. A handle is fixedly connected to one side of the outer surface of the base plate, and a control button is fixedly connected to the top of the outer surface of the handle. A charging slot is opened on the top surface of the base plate, and an electromagnetic coil is fixedly connected to the other side of the outer surface of the base plate. A connection structure is provided on both sides of the interior of the protective plate. The connection structure includes a connecting block and an insertion slot, and there are two sets of connecting blocks, which are respectively fixedly connected to both ends of the outer surface of the base plate.

[0007] Preferably, the outer surface of the grip is covered with a sponge pad, which enhances the user's comfort when holding the device.

[0008] Preferably, the connection structure further includes slots, and there are four sets of slots. The four sets of slots are respectively opened at the upper and lower ends of the two sets of connecting blocks. The outer surface of the protective plate has insertion slots at both ends, and the upper and lower ends of the insertion slots have grooves. A spring is fixedly connected inside the groove, and a limit block is fixedly connected to one end of the spring. A locking block is fixedly connected to the side of the outer surface of the limit block away from the spring. This design allows the protective plate to be fitted onto the outer surface of the electromagnetic coil and the base plate and to perform positioning operations on them.

[0009] Preferably, the external dimensions of the connecting block are adapted to the internal dimensions of the insertion slot, a design that allows the connecting block to be accurately inserted into the insertion slot.

[0010] Preferably, the internal dimensions of the groove are adapted to the external dimensions of the limiting block, which makes the movement of the locking block more stable.

[0011] Preferably, both sides of the outer surface of the card block are designed to be inclined, and the external dimensions of the card block are adapted to the internal dimensions of the card slot. This design allows the card block to be accurately inserted into the inside of the card slot.

[0012] The technical effects and advantages of this utility model are as follows: This utility model allows the electromagnetic coil to be placed on the outside of the locking mechanism by holding the handle. Pressing the control button activates the electromagnetic coil, enabling it to perform an electromagnetic unlocking operation on the locking mechanism. After unlocking, the magnetic force of the electromagnetic coil is canceled by not pressing the control button again. This design allows the entire device to be handheld, which is more convenient than the traditional fixed design. In large systems with multiple identical or similar locking mechanisms, each locking point does not need to have a complete set of electromagnets and corresponding wiring and control circuits installed independently. This saves on system installation costs and subsequent maintenance workload. It also avoids the situation where the electromagnetic unlocking device fails in emergency situations such as main power failure or control system failure, maintaining the stability of the device during use and thus improving the practicality and convenience of the device to a certain extent. By covering the outer surface of the electromagnetic coil and the base plate with a protective plate, and inserting two sets of connecting blocks into the insertion slots, the outer surface of the connecting blocks will abut against the inclined surface of the locking block. When the pushing force is greater than the spring force, the locking block can be forced to move back into the groove until it reaches the appropriate position. Then, the connecting block can be locked into the bottom position inside the insertion slot. At this time, the locking block and the slot are in corresponding positions. Under the elastic action of the spring, the locking block can be ejected outward and locked into the slot to position the connecting block after it has moved. After the equipment is used up, the protective plate can be covered on the outer surface of the electromagnetic coil and the base plate to prevent the electromagnetic coil or the base plate from being bumped or scratched by other tools during storage. This protects the electromagnetic coil and the base plate and maintains the stable performance of the electromagnetic coil, thereby improving the practicality of the equipment to a certain extent. Moreover, its overall structure is simple and reasonable, highly practical, and easy to promote and apply. Attached Figure Description

[0018] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The unlocking device involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] Example 1, as Figures 1-4 As shown, this embodiment proposes an electromagnetic unlocking device for a locking mechanism, comprising: The base plate 1 and the protective plate 2 are provided. A handle 3 is fixedly connected to one side of the outer surface of the base plate 1, and a control button 4 is fixedly connected to the top of the outer surface of the handle 3. A charging slot 5 is opened on the top surface of the base plate 1, and an electromagnetic coil 6 is fixedly connected to the other side of the outer surface of the base plate 1. A connecting structure 7 is provided on both sides of the interior of the protective plate 2. With the help of the charging slot 5, the device can be charged by the charging device and stored in conjunction with the storage battery inside the base plate 1. The outer surface of the grip bar 3 is covered with a sponge pad. This sponge pad has a certain degree of softness. When the user holds the grip bar 3, they can hold the outer side covered with the sponge pad, which enhances the comfort during use. The connecting structure 7 includes a connecting block 71 and an insertion slot 73. There are two sets of connecting blocks 71, which are fixedly connected to both ends of the outer surface of the base plate 1. The connecting structure 7 also includes a slot 72, which is provided in four sets. The four sets of slots 72 are respectively opened at the upper and lower ends of the two sets of connecting blocks 71. Insertion slots 73 are opened at both ends of one side of the outer surface of the protective plate 2. Grooves 74 are opened at both the upper and lower ends of the insertion slots 73. A spring 75 is fixedly connected inside the groove 74. A limit block 76 is fixedly connected to one end of the spring 75. A locking block 77 is fixedly connected to the side of the outer surface of the limit block 76 away from the spring 75. This design can shield the electromagnetic coil 6 and the base plate 1 under the action of the protective plate 2. In the event of a collision, the electromagnetic coil 6 and the base plate 1 can be protected as much as possible by the protective effect of the protective plate 2. The external dimensions of the connecting block 71 are adapted to the internal dimensions of the insertion slot 73. This design allows the connecting block 71 to move along the inner wall of the insertion slot 73, ensuring that the installation position of the protective plate 2 remains consistent each time. The internal dimensions of the groove 74 are adapted to the external dimensions of the limiting block 76. This design can limit the locking block 77 and prevent the locking block 77 from dislodging from the inside of the groove 74. Both sides of the outer surface of the locking block 77 are inclined, and the external dimensions of the locking block 77 are adapted to the internal dimensions of the slot 72. This design allows the outer surface of the connecting block 71 to abut against the inclined surface of one side of the locking block 77 when the connecting block 71 is inserted into the insertion slot 73, and the inner wall surface of the slot 72 to abut against the inclined surface of the other side of the locking block 77 when the connecting block 71 is pulled out of the insertion slot 73, making the insertion or removal of the connecting block 71 smoother.

[0020] The electromagnetic coil 6 in this application is a product that can be purchased directly from the market. Its principle, connection method and control method are all existing technologies well known to those skilled in the art, so they will not be described in detail here.

[0021] Working principle: When using the equipment, hold the handle 3 and place the electromagnetic coil 6 on the outside of the locking mechanism that needs to be unlocked. Then press the control button 4 to activate the electromagnetic coil 6, which will perform an electromagnetic unlocking operation on the locking mechanism. After unlocking, stop pressing the control button 4 to cancel the magnetic force of the electromagnetic coil 6. Repeat the above operation to unlock multiple locking mechanisms. This design allows the entire equipment to be handheld, making it convenient for staff to carry and greatly improving its convenience. Compared with the traditional fixed design, it reduces a lot of installation wiring, thereby saving installation costs and making subsequent maintenance more convenient. It also avoids the situation where the electromagnetic unlocking device fails in case of emergency due to main power failure or control system failure, thus maintaining the stable operation of the equipment. After the equipment is used, the protective plate 2 can be fitted onto the outer surface of the electromagnetic coil 6 and the base plate 1, and the two sets of connecting blocks 71 can be inserted into the insertion slot 73. At this time, the outer surface of the connecting block 71 will abut against the inclined surface of the locking block 77. When the pushing force is greater than the elastic force of the spring 75, the locking block 77 can be pressed to move back into the groove 74 until the locking block 77 moves back to the appropriate position. Then, the connecting block 71 can be inserted into the bottom position inside the insertion slot 73. At this time, the locking block 77 and the slot 72 are in corresponding positions. Under the elastic action of the spring 75, the locking block 77 can be ejected outward and inserted into the slot 72 to perform a positioning operation on the moved position of the connecting block 71. The protective plate 2 is fitted onto the outer surface of the electromagnetic coil 6 and the base plate 1 to protect them. In the event of a collision, it helps to prevent damage to the electromagnetic coil 6 and the base plate 1. When the equipment is used again, the protective plate 2 can be pulled outward. When the pulling force is greater than the elastic force of the spring 75, the inner wall surface of the slot 72 will press against the inclined surface of the locking block 77, causing the locking block 77 to move back into the groove 74 until the locking block 77 is disengaged from the slot 72. This cancels the positioning effect on the connecting block 71. At this point, the protective plate 2 can be removed from the outer surface of the base plate 1 and the electromagnetic coil 6, and the handle 3 can be used. This is the complete working principle of this utility model.
