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 sliding door electromagnetic lock. Background Technology

[0002] Electromagnetic locks, also known as magnetic locks, are locks that operate on the principle of electromagnetism. When an electric current passes through a silicon steel sheet, the electromagnetic lock generates a strong magnetic force, tightly holding the metal plate in place to lock the door. Electromagnetic locks lack complex mechanical structures and latches, making them suitable for controlling access to security doors, escape doors, or fire doors.

[0003] Electromagnetic locks are commonly installed on hinged and sliding doors in industrial production to form a locking structure and ensure operational safety. However, existing sliding door electromagnetic lock installation structures have the following drawbacks: 1. The electromagnetic lock matching unit and switch unit are installed separately behind the door frame and door leaf, making it inconvenient to adjust their positions, resulting in misalignment and increased installation difficulty; 2. The installation structure is relatively complex, making disassembly and assembly inconvenient; 3. The installation is not stable or reliable enough. After long-term use, the installation rigidity decreases, making the electromagnetic lock matching unit and switch unit prone to misalignment.

[0004] Therefore, how to design a sliding door electromagnetic lock installation structure that is simpler and more reasonable in structure, easier to install and adjust, and more stable and reliable in installation has become a technical problem that needs 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 a sliding door electromagnetic lock installation structure with a simpler and more reasonable structure, which is easier to install and adjust, and more stable and reliable in installation.

[0006] To achieve the above objectives, this utility model provides a sliding door electromagnetic lock installation structure, including a door leaf slidably mounted on a door frame; an electromagnetic lock is installed between the door frame and the door leaf; the electromagnetic lock includes a switch body mounted on the inner side of the door frame vertical rod via a mounting bracket, and a matching body mounted and fixed on the door leaf; and after the door leaf moves towards the switch body on the door frame vertical rod within the door frame, the working end of the matching body on the door leaf can be magnetically attracted with the magnetic end of the switch body to restrict the sliding of the door leaf within the door frame; characterized in that; a vertically arranged T-shaped mounting groove is provided on the inner side of the door frame vertical rod, the mounting bracket includes a bracket block attached to the inner side of the door frame vertical rod, and a pair of fixing screws are provided, with the heads of the fixing screws being vertically slidable and fitted in the mounting groove, and the threaded ends of the fixing screws each passing through a mating hole on the bracket block, and each threaded end of the fixing screw is provided with a locking nut.

[0007] Thus, in the aforementioned sliding door electromagnetic lock installation structure, a T-shaped mounting groove is provided on the door frame vertical rod. The bracket block on the mounting bracket is connected to the mounting bracket by fixing screws. This allows the switch body mounted on the mounting bracket to be adjusted vertically as needed, ensuring better alignment of the switch body during installation and more reliable operation. Furthermore, after a period of use, the vertical position of the switch body can be adjusted more easily, resulting in better matching between the two.

[0008] As an optimization, the mounting bracket includes a horizontally arranged bracket plate, and the horizontal mounting surface of the switch body is attached to one side surface of the bracket plate. The bracket plate is provided with a long strip-shaped mounting hole, in which two mounting screws are arranged in pairs, and the threaded end of the mounting screw can pass through the mounting hole and be threadedly connected in the threaded connection hole of the mounting surface of the switch body, thereby connecting and fixing the switch body to the bracket plate.

[0009] This design simplifies the mounting bracket's structure, making it easier to install and arrange the switch body, and resulting in greater stability after installation. Furthermore, the elongated mounting holes allow for adjustment of the switch body's position, ensuring better alignment with the matching unit and reducing installation difficulty.

[0010] As an optimization, one end of the support plate is vertically bent to form a bent section, and the outer end of the bent section is then horizontally bent outward to form a fixing plate. Both sides of the fixing plate extend outward to form extension sections, and the outer ends of the extension sections are then vertically bent outward to form the support block; and one of the support blocks is attached to the inner side of the door frame vertical rod.

[0011] This makes the structural design of the mounting bracket simpler and more reasonable, easier to install, and provides higher structural strength.

[0012] Furthermore, the support plate, the bracket plate, and the fixing plate are formed as a single piece.

[0013] As an optimization, a deformation notch with an overall U-shaped structure is provided at the outer end of the fixing plate.

[0014] This makes the structural design simpler and more reasonable.

[0015] As an optimization, a long strip-shaped mounting pad is fixed to the inner side of the door leaf and arranged horizontally. A connecting bracket is connected to the matching body and fixed to the mounting pad.

[0016] By setting up mounting pads, the installation strength is increased, and the installation of the connecting brackets is also made easier.

[0017] As an optimization, the connecting bracket includes a connecting plate. The matching device's main body end face has two vertically outwardly arranged connecting support plates. The outer ends of each connecting support plate are bent vertically outward to form a connecting support plate mounting section, and the connecting support plate mounting sections are respectively attached to the surface of the connecting plate. Each connecting support plate mounting section is provided with an elongated fixing hole. A fixing mating hole is provided on the connecting plate corresponding to the fixing hole. The fixing mating hole and the fixing hole are respectively used to arrange connecting bolts to connect and fix the connecting plate and the connecting support plate mounting section together.

[0018] This allows the position between the connecting bracket and the matching unit to be adjusted, making installation more convenient and allowing for appropriate adjustments as needed.

[0019] As an optimization, the end of the connecting plate opposite to the door leaf is bent to form a connecting plate. The two sides of the outer end of the connecting plate protrude outward to form a fixing protrusion. One of the fixing protrusions is fixed to the mounting pad by a connecting screw.

[0020] In this way, the overall structural design of the connecting bracket is simpler, easier to process and manufacture, and easier to install on the mounting pad.

[0021] As an optimization, a weight-reducing hole with a rectangular structure is provided in the middle of the connecting plate.

[0022] In this way, by setting weight-reduction holes, the requirements for lightweight design can be better met.

[0023] As an optimization, the door frame includes two horizontal door frame bars and two vertical door frame bars connected to form a rectangular frame structure; and a door leaf is slidably fitted between the two horizontal door frame bars.

[0024] This makes the structural design of the door frame simpler and more reasonable.

[0025] As an optimization, electromagnetic locks are installed between the upper end of the door frame vertical bar and the door leaf, and between the lower end of the door frame vertical bar and the door leaf.

[0026] By setting up two electromagnetic locks, the sliding of the door leaf within the door frame can be better restricted.

[0027] In summary, the above-mentioned sliding door electromagnetic lock installation structure has the advantages of simpler and more reasonable structural design, easier installation and adjustment, and more stable and reliable installation. Attached Figure Description
