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 hinged 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, firmly 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 hinged door electromagnetic lock installation structures have the following drawbacks: 1. It is inconvenient to adjust the position of the electromagnetic lock matching unit or switch unit, resulting in misalignment and installation difficulties; 2. The installation structure is not stable and reliable enough, causing the electromagnetic lock matching unit and switch unit to loosen easily during frequent opening and closing of the hinged door, leading to unreliable locking; 3. The mounting bracket structure is not reasonably designed, making installation inconvenient.

[0004] Therefore, how to design a hinge door electromagnetic lock installation structure that is simpler and more reasonable in structure, easier to install and adjust, more stable and reliable in installation, and more convenient to install 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 hinge door electromagnetic lock installation structure that is simpler and more reasonable in structure, easier to install and adjust, more stable and reliable in installation, and more convenient to install.

[0006] To achieve the above objectives, this utility model provides a hinged door electromagnetic lock installation structure, including a door leaf installed on a door frame; an electromagnetic lock is installed between the door frame and the door leaf; the electromagnetic lock includes a switch body installed on the inner side of the door frame crossbar via a mounting bracket, and a matching body installed and fixed on the door leaf; and when the door leaf is closed, the magnetic end of the switch body can be magnetically attracted to the working end of the matching body to restrict the rotation of the door leaf on the door frame; characterized in that; a T-shaped mounting groove is provided on the inner side of the door frame crossbar, the mounting bracket includes a fixing plate attached to the door frame crossbar, and a pair of fixing screws are provided, with the heads of the fixing screws slidably fitted in the mounting groove, so that the threaded ends of the fixing screws each pass through a vertically arranged elongated mating hole on the fixing plate, and a locking nut is provided on the threaded ends of the fixing screws.

[0007] In this way, the switch body is mounted on the door frame crossbar using a mounting bracket. The door frame crossbar has a T-shaped mounting groove, and the mounting bracket's fixing plate is attached to the crossbar. Pairs of fixing screws are then arranged within the mounting groove, passing through mating holes on the fixing plate, and lock nuts are used to secure the switch body. This mounting bracket design allows for horizontal and vertical position adjustment of the switch body, enabling better alignment and a smoother fit with the matching device, thus reducing installation difficulty and making installation more convenient.

[0008] As an optimization, a rectangular mounting plate with a horizontal arrangement is connected and fixed to the inner side of the door leaf, so that the two mounting brackets on the matching body are respectively attached to the inner side of the mounting plate. Each of the mounting brackets has a long strip-shaped vertical mounting hole at its outer end for mounting screws, and the mounting screws can be threaded into the end of the mounting plate.

[0009] In this way, by setting up the mounting plate, it is easier to install and fix the main body of the matcher.

[0010] As an optimization, the mounting bracket includes a rectangular plate structure designed and horizontally arranged bracket plate, with one end of the bracket plate opposite to the inner side of the door frame crossbar bent upward to form the fixing plate; the bracket plate is provided with a long strip-shaped connecting hole along its length, the connecting hole is used to arrange two or more fastening screws at intervals, and the lower end of the fastening screw can be threaded into the threaded hole on the upper surface of the switch body.

[0011] This design of the mounting bracket is more reasonable, allowing for better installation of the switch body on the door frame crossbar. It also facilitates adjustment of the vertical installation position of the switch body.

[0012] As an optimization, a rectangular pad is provided between the bracket plate and the switch body. The pad has a U-shaped clearance for the fastening screw to pass through, and the upper and lower surfaces of the pad are respectively attached to the bracket plate and the switch body for support.

[0013] By using pads, installation becomes easier and the switch body can be supported.

[0014] As an optimization, the mounting plate includes an outer section, the inner end of which is bent downward to form a middle section, and the lower end of the middle section is bent inward horizontally to form an inner section. The connecting hole is provided on the outer section, and a circular through hole is provided on the inner section.

[0015] In this way, the mounting plate is designed as an outer section, a middle section, and an inner section, which is a more reasonable design.

[0016] As an optimization, the two sides of the mounting plate are bent upward to form a reinforced side plate, and the end of the reinforced side plate opposite to the door frame crossbar is bent inward to form a support block, so that the support blocks are attached to the surface of the fixed plate, and each support block is provided with a long strip-shaped clearance hole corresponding to the mating hole.

[0017] In this way, by forming reinforced side plates and support blocks, the overall mounting bracket structure can be made stronger and more stable after installation.

[0018] Furthermore, a chamfered structure is provided on the upper far end of the reinforced side plate.

[0019] As an optimization, a weight-reducing port with a long strip structure that runs through the wall thickness is provided at the joint position of the mounting plate and the reinforcing side plate.

[0020] In this way, the structural design becomes simpler and more reasonable, and the weight is reduced.

[0021] As an optimization, the switch body is installed on the door frame crossbar at the upper end of the door frame, and the matching unit body is installed on the inner side of the upper end of the door leaf.

[0022] This makes the installation positions of the switch body and the matching unit more rationally designed.

[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 door leaves are hinged and installed on each of the two vertical door frame bars.

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

[0025] In summary, the above-mentioned hinge door electromagnetic lock installation structure has the advantages of simpler and more reasonable structural design, easier installation and adjustment, more stable and reliable installation, and greater ease of installation.
