Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of magnetic lock accessories, in particular to a magnetic lock bracket. Background Art
[0002] The design of magnetic lock is the same as that of electromagnet. When the current passes through the silicon steel sheet, the electromagnetic lock will generate a strong suction force to tightly absorb the adsorption iron plate to achieve the effect of locking the door. Currently, frameless glass doors on the market are usually unable to be installed with holes. Magnetic locks usually use U-shaped brackets to buckle on the upper and lower edges of the glass door frame and the glass door. The U-shaped bracket used to connect the electromagnet is installed inverted and clamped on the glass door frame by means of gasket resistance. However, during the daily use of frameless glass doors, the opening and closing of the door will cause high-frequency vibration of the glass door frame. Over time, the inverted U-shaped bracket will gradually loosen and slide down until it is stuck on the glass door and cannot be opened and closed smoothly. Utility Model Content

[0029] Working principle:
[0030] In the utility model, during the installation of the magnetic lock, the wedge-shaped strip 7 is fixed to the glass door frame 1 by glass glue, the upper bracket mechanism is buckled on the lower edge of the glass door frame 1 through the U-shaped groove plate 5, the rubber gasket 13 of the front inner wall of the U-shaped groove plate 5 is attached to the front side wall of the glass door frame 1, and an installation gap is provided between the rear side wall of the U-shaped groove plate 5 and the rear side of the glass door frame 1, and the locking component can be placed in the installation gap, and the set screw 8 is rotated to resist the locking component to slide toward the glass door frame 1 until the rubber gasket 13 at the front end of the resistance strip 10 resists The rubber suction cup 14 on the upper side of the locking plate contacts and is attracted to the glass door frame 1. During the attraction process, the air in the rubber suction cup 14 can be discharged to form a negative pressure and be tightly attached to the glass door frame 1 under the support of the magnetic block 15. The set screw 18 is continuously tightened until the lower end of the locking plate contacts the wedge block. The inverted U-groove plate 17 of the lower bracket mechanism is buckled on the glass door 2 and the set screw 2 is tightened to clamp the fitting gasket 20 on the glass door 2. The installation of the upper bracket mechanism and the lower bracket mechanism of the magnetic lock is completed.
[0031] During use, the vibration generated by opening and closing the door will cause the upper bracket mechanism to have a downward trend relative to the glass door frame 1. Under the effect of the downward trend, the inclined surface of the wedge strip 7 will resist the rotation of the locking plate around the hinge position, and the upper end will move closer to the glass door frame 1, so that the rubber suction cup 14 can fit more closely on the glass door frame 1 to be fixed, thereby preventing the upper bracket mechanism from sliding down.
