Technical Field
[0001] This utility model relates to the field of electromagnetic lock technology, and in particular to an electromagnetic lock safety switch structure. Background Technology
[0002] A safety switch is essentially a control device designed for certain equipment to ensure that the equipment always operates below (or equal to) its rated value or within its safe operating range. Taking a safety door switch as an example: A safety door switch consists of two interconnected parts: the switch body and the switch's operating mechanism. The switch body typically comprises a solenoid valve connected to a separate power source and a key that controls the solenoid valve's mechanical movement. The switch's operating mechanism, or core mechanism, directly controls whether the load is energized. The moving iron core of the solenoid valve is linked to the mechanical part of the operating mechanism, thereby controlling the connection of the electrical circuit.
[0003] The applicant has developed a mechanism and electromagnetic safety switch for controlling the simultaneous on / off of multiple circuits, patent number (CN202222009835.6), and a mechanism and electromagnetic mounting switch for controlling the simultaneous on / off of multiple circuits, patent number (CN202210911654.4). However, in the structures of the aforementioned patented products, the internal moving push rod and electromagnet assembly are directly exposed after the cover on top of the housing is opened. The existing patent structures lack a pin-like covering and positioning structure for the moving push rod and electromagnet assembly, resulting in poor stability and wiring safety after installation; furthermore, they fail to adequately protect the two components.
[0004] Therefore, how to design an electromagnetic lock safety switch structure that is simpler and more reasonable, can better cover and protect the moving push rod and electromagnet assembly, can better improve installation stability, and can better improve wiring safety has become a technical problem that needs to be solved by those skilled in the art. Utility Model Content

The two outer sides of the protruding strip extend horizontally outward to form a connecting plate, and the outer sides of the connecting plate bend downward to form a plug-in side plate.
[0013] This makes the design of the entire electromagnet cover protection plate simpler and more reasonable.
[0014] As an optimization, two clearance openings are provided at intervals on the connecting plate.
[0015] In this way, the clearance opening can be used to check whether the assembly is in place.
[0016] As an optimization, a disassembly notch is provided at the middle of one end of the main body plate, extending through its thickness direction; and a force groove is formed at the middle of the lower surface of the other end of the main body plate by pulling it upward.
[0017] In this way, by setting disassembly notches and force grooves, the entire component can be disassembled more easily.
[0018] As an optimization, longitudinally arranged abutment protrusions are provided on the lower surface of the main plate and on both sides of the disassembly notch, and a connecting protrusion is provided between the inner ends of the two abutment protrusions; a transversely arranged crossbar is provided corresponding to the inner ends of the two abutment protrusions.
[0019] In this way, the formed abutment protrusions and connecting protrusions are better pressed onto the components below.
[0020] As an optimization, the push rod cover protection component includes a push rod cover protection plate horizontally arranged above the movable push rod; each of the two sides of one end of the push rod cover protection plate protrudes outward to form a snap-fit protrusion, and the snap-fit protrusion can extend into the screw assembly that fits in the switch housing; a cover side plate is provided on each side of the lower surface of the push rod cover protection plate, and the movable push rod is located between the two cover side plates.
[0021] In this way, the structural design of the push rod covering protection component is simpler and more reasonable, and easier to install and arrange.
[0022] As an optimization, a U-shaped clearance opening is provided at one end of the push rod cover protection plate; the middle of the other end of the push rod cover protection plate extends forward to form an extension, and a vertically arranged protruding plate is integrally formed above the extension, and an opening force port is provided on the protruding plate that extends horizontally through its thickness direction.
[0023] This makes the installation and disassembly of the entire component much easier.
[0024] As an optimization, a deformation notch is provided on the push rod cover protection plate, corresponding to the rear position of the snap-fit protrusion, and extending through the thickness direction of the push rod cover protection plate.
[0025] This design of the deformation notch makes it easier to install and remove the box, and the snap-fit protrusion has better bending and deformation capabilities.
[0026] Furthermore, vertically arranged connecting protrusions are provided on the rear side of the outer side of the cover plate.
[0027] Furthermore, a chamfered structure is provided on the lower front end of the cover side panel.
[0028] In summary, the electromagnetic lock safety switch structure described above features a simpler and more reasonable structure, better coverage and protection for the moving push rod and electromagnet assembly, improved installation stability, and enhanced wiring safety.
