Description

Technical Field

[0001] This utility model belongs to the field of outdoor electromagnetic lock technology, specifically relating to an outdoor electromagnetic lock with an outer protective cover. Background Technology

[0002] Electromagnetic locks are electronic locks designed based on the principle of electromagnetic induction. They achieve the locking function by using the magnetic force generated by energizing an electromagnet. Their core structure includes an electromagnet assembly, an adsorption plate, and a control module. The working process relies on the switching of current to lock and release the door. They are mainly used in special scenarios such as fire lanes and power facilities that require automatic unlocking when power is cut off. Outdoor electromagnetic locks are electromagnetic locks used in open-air outdoor environments.

[0003] Although outdoor electromagnetic locks have an outer shell structure, they cannot achieve a sealing function, which leads to the electromagnetic lock being corroded by moisture and dust particles when used outdoors. This causes corrosion, short circuits, and problems such as poor extension and retraction and jamming of the internal electrical components of the outdoor electromagnetic lock. To address this, we propose an outdoor electromagnetic lock with an outer protective cover. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-5 The outdoor electromagnetic lock with an outer protective cover provided by this utility model includes:

[0029] There are two semi-open protective covers 1. The two semi-open protective covers 1 are inserted and sealed on the outside of the outdoor electromagnetic lock 2. The two semi-open protective covers 1 are connected by insertion, and a sealing strip is provided at the insertion connection between the two semi-open protective covers 1.

[0030] The sealing plug ring 3 is located between the two semi-open protective covers 1 at the reset knob 4 on the outdoor electromagnetic lock 2;

[0031] The sealing gasket 5 is installed inside the two semi-open protective covers 1 at the corresponding lock tongue 6 on the outdoor electromagnetic lock 2.

[0032] A foam layer is filled between the two semi-open protective covers 1 and the outdoor electromagnetic lock 2, forming a filling cavity between the outdoor electromagnetic lock 2 and the two semi-open protective covers 1, and the foam layer is filled and placed in the filling cavity.
