Description

Technical Field

[0001] This utility model relates to the field of electromagnetic door lock technology, and in particular to an installation structure for a small electromagnetic lock safety door switch. Background Technology

[0002] The design of a magnetic lock is similar to that of an electromagnet. When current passes through a silicon steel sheet, the electromagnetic lock generates a strong attraction force that tightly holds the iron plate, thus locking the door. Even a small current can produce a tremendous magnetic force. Once the access control system that controls the electromagnetic lock's power supply correctly identifies the person, it cuts off the power, and the electromagnetic lock loses its attraction force, allowing the door to open.

[0003] Chinese patent (CN218293192U) discloses an easy-to-install electromagnetic lock; however, the electromagnetic lock devices disclosed in the prior art only have a single installation structure, which makes it impossible to assemble and change the installation structure as needed, and thus cannot meet different installation scenarios.

[0004] Therefore, how to design a small electromagnetic lock safety door switch with a simpler and more reasonable structural design, easier to disassemble and assemble, and more convenient to assemble into different installation structures according to different installation spaces to better improve installation adaptability has become a technical problem to be solved by those skilled in the art. Utility Model Content

[0005] In view of the above-mentioned defects of the prior art, the technical problem to be solved by this utility model is how to design an installation structure for a small electromagnetic lock safety door switch that is simpler and more reasonable in structure design, easier to disassemble and assemble, and more convenient to assemble into different installation structures according to different installation spaces in order to better improve installation adaptability.

[0006] To achieve the above objectives, this utility model provides an installation structure for a small electromagnetic lock safety door switch, including an electromagnetic lock body, which comprises a matching housing and a switch body, and a left mounting structure and a right mounting structure are respectively provided on the matching housing and the switch body; characterized in that: the left mounting structure includes an adjusting plate rotatably mounted on the outer end face of the matching housing, and a rotation limiting structure is provided between the adjusting plate and the matching housing to restrict the rotation of the adjusting plate; both ends of the adjusting plate are bent outward to form support plates, and the outer ends of the support plates are bent outward to form connecting plates, and each connecting plate has an elongated hole with a long strip structure for connecting to the left mounting plate; the right mounting structure includes a first fixing hole respectively provided on two opposing surfaces of one set of the switch body, and a second fixing hole provided on one side of the switch body; and the first fixing hole and the second fixing hole can each be connected to the right mounting plate.

[0007] Thus, in the above-mentioned device structure, the adjusting plate can rotate, which allows the support plate and connecting plate to rotate as well, and the left mounting plate mounted on the connecting plate can also rotate. Furthermore, it is possible to replace and assemble left mounting plates with different structures. Secondly, by setting the first fixing hole and the second fixing hole on the switch body, right mounting plates with different structures can be installed, so that the entire device can have different installation structures, thereby better adapting to different installation scenarios.

[0008] As an optimization, the outer end face of the matching device housing is recessed to form a mounting cavity. The adjusting plate is attached to the bottom surface inside the mounting cavity. An adjusting screw is provided at the center position of the adjusting plate, and the adjusting screw passes through a through hole in the middle position of the adjusting plate and is threaded into a threaded connection hole in the bottom surface of the mounting cavity. A helical spring is provided on the adjusting screw, and the two ends of the helical spring abut against the adjusting plate and the head of the adjusting screw to push the adjusting plate to be attached and supported on the bottom surface of the mounting cavity.

[0009] This makes the overall structural design more compact and facilitates the installation and arrangement of the adjustment plates.

[0010] As an optimization, a washer is also provided on the adjusting screw. The washer is positioned close to the head of the adjusting screw, and one end of the coil spring is supported against the washer.

[0011] In this way, by designing the washer, the end of the coil spring can better abut against the head of the adjusting screw.

[0012] As an optimization, the rotation limiting structure includes a limiting block protruding outward on the bottom surface of the mounting cavity. The limiting block consists of four rectangular blocks, which are arranged in pairs on the outer sides of both ends of the longitudinal direction of the adjusting plate.

[0013] In this way, when it is necessary to adjust the angle of the adjusting plate, the adjusting plate can be pulled outward and the helical spring can be compressed, so that the adjusting plate moves towards the bottom surface away from the mounting cavity. When the inner surface of the adjusting plate moves to the outer side of the limit block, the adjusting plate can be rotated, so that the support plate and the connecting plate rotate together. After rotating 90 degrees, the adjusting plate is released, so that the helical spring pushes the adjusting plate to be supported against the bottom surface of the mounting cavity. The adjusting plate is then located between the four limit blocks, and the limit blocks can restrict the adjusting plate from continuing to rotate.

[0014] Furthermore, the limit block has an L-shaped cross-section design.

[0015] As an optimization, the adjusting plate, support plate, and connecting plate are integrally formed.

[0016] This makes the structural design simpler and more reasonable, and easier to process and manufacture.

[0017] As an optimization, the left mounting plate is a rectangular plate, and the two ends of the left mounting plate are respectively attached to the two connecting plates. A circular clearance hole is provided on the left mounting plate at the middle position corresponding to the elongated hole, and a threaded connection hole is provided on the left mounting plate at one end corresponding to the elongated hole.

[0018] This provides a left mounting plate with one of the structural forms, and the structural design of the left mounting plate is simpler and more reasonable; it is suitable for a specific installation scenario.

[0019] As an optimization, the left mounting plate includes a left mounting plate connecting part with a rectangular plate structure and both ends respectively attached to the two connecting plates. Each end of the left mounting plate connecting part has a docking hole with a long strip structure design corresponding to the long strip hole. One side of the left mounting plate connecting part is bent inward to form a left mounting plate mounting part, and each end of the left mounting plate mounting part has a left mounting hole with a long strip structure design.

[0020] This results in a left mounting plate with an alternative structural form, and the structural design of the left mounting plate is simpler and more reasonable; it is suitable for a specific installation scenario.

[0021] As an optimization, the right mounting plate includes a right mounting plate connecting part with a rectangular plate structure and attached to a surface of the switch body, and a first connecting hole with an elongated structure is provided on the right mounting plate connecting part corresponding to the first fixing hole; the two ends of the right mounting plate connecting part are continuously bent and extended outward to form a right mounting plate mounting part, and a first right mounting hole with an elongated structure is provided on the right mounting plate mounting part.

[0022] Thus, the right mounting plate, which is one of the structural forms, has a simple structural design and is easy to install; and it is also suitable for a specific installation scenario.

[0023] As an optimization, the right mounting plate includes a right mounting plate fixing part with a rectangular plate structure and attached to one side of the switch body. The right mounting plate fixing part has a second connecting hole with an elongated structure corresponding to the second fixing hole. The two sides of the right mounting plate fixing part are bent outward to form side plates, and the inner end of the right mounting plate fixing part is bent outward to form a surrounding plate. The surrounding plate has two pairs of second right mounting holes with an elongated structure. A circular hole is also provided at the outer end of the right mounting plate fixing part.

[0024] This results in a right mounting plate with an alternative structural form, and the structural design of the right mounting plate is simpler and more reasonable; it is also suitable for a specific installation scenario.

[0025] In summary, the above-described device structure allows for adjustment of the angle of the left mounting plate and replacement of the left mounting plate with different structural forms, as well as replacement of the right mounting plate with different structural forms. This makes the entire device structure more convenient to assemble into different installation structures according to different installation spaces, thereby improving installation adaptability. It also features easier disassembly and assembly. Attached Figure Description

[0033] like Figure 1 , 2As shown in Figure 3, an installation structure for a small electromagnetic lock safety door switch includes an electromagnetic lock body, which includes a matching housing 1 and a switch body 2. A left mounting structure and a right mounting structure are respectively provided on the matching housing and the switch body. The left mounting structure includes an adjusting plate 3 rotatably mounted on the outer end face of the matching housing. A rotation limiting structure is provided between the adjusting plate and the matching housing to restrict the rotation of the adjusting plate.

Furthermore, it is possible to replace and assemble left mounting plates with different structures. Secondly, by setting the first fixing hole and the second fixing hole on the switch body, right mounting plates with different structures can be installed, so that the entire device can have different installation structures, thereby better adapting to different installation scenarios.

[0035] In this specific embodiment, the outer end face of the matching device housing is recessed to form a mounting cavity 9.

[0037] In this specific embodiment, a washer 12 is also provided on the adjusting screw. The washer is attached to the head of the adjusting screw, and one end of the helical spring is supported on the washer.

[0038] In this way, by designing the washer, the end of the coil spring can better abut against the head of the adjusting screw.

[0039] In this specific embodiment, the rotation limiting structure includes a limiting block 13 protruding outward and disposed on the bottom surface of the mounting cavity. The limiting blocks are four in a rectangular distribution, and each is arranged in pairs on the outer sides of both ends of the longitudinal direction of the adjusting plate.

[0040] In this way, when it is necessary to adjust the angle of the adjusting plate, the adjusting plate can be pulled outward and the helical spring can be compressed, so that the adjusting plate moves towards the bottom surface away from the mounting cavity. When the inner surface of the adjusting plate moves to the outer side of the limit block, the adjusting plate can be rotated, so that the support plate and the connecting plate rotate together. After rotating 90 degrees, the adjusting plate is released, so that the helical spring pushes the adjusting plate to be supported against the bottom surface of the mounting cavity. The adjusting plate is then located between the four limit blocks, and the limit blocks can restrict the adjusting plate from continuing to rotate.

[0041] Furthermore, the limit block has an L-shaped cross-section design.

[0042] In this specific embodiment, the adjusting plate, the support plate, and the connecting plate are integrally formed.

One side of the left mounting plate connecting part is bent inward to form a left mounting plate mounting part 19. Each end of the left mounting plate mounting part has a long strip-shaped left mounting hole 20.

[0047] This results in a left mounting plate with an alternative structural form, and the structural design of the left mounting plate is simpler and more reasonable; it is suitable for a specific installation scenario.
