Embodiment Construction

[0009] figure 1 It is a schematic diagram of the proximity switch door lock system. A permanent magnet 1 is fixed near the lock hole 2 on the door lock, and a groove (not shown in the figure) is provided along the main body of the key, and a Hall proximity switch 3 is embedded in the groove, and fixed at the front of the key handle There are LED lamp beads 4 and a button battery 5 that supplies power to the LED lamp beads. The wires (not shown) connecting the Hall proximity switch 3 to the LED lamp beads and the button battery 5 are arranged along the groove, and are connected to the Hall through the inner surface. The matching fixture (not shown in the figure) on the outer surface of the proximity switch 3 fills up the groove and fixes it.

[0010] When in use, put the key chain close to the door lock. When the distance between the key and the permanent magnet indicated by 1 is reduced to a certain range, the Hall proximity switch 3 is turned on, and the LED lamp bead 4 on t...

Abstract

The invention relates to a key with a proximity switch. The key comprises a key main body and a key handle, and is characterized in that a groove is formed in the key main body along the direction ofthe key, the Hall proximity switch is fixed in the groove, an LED lamp bead and a button battery are fixed to the position, close to the front part of the key handle, of the key handle, a wire which enables the Hall proximity switch, the LED lamp bead and the button battery to be connected is arranged along the groove, and the groove is leveled and fixed well through a fixing piece with the innersurface matched with the outer surface of the Hall proximity switch. According to the key with the proximity switch, people can conveniently find the corresponding key as soon as possible in the dark,moreover, illumination can be provided, and then people can accurately find the position of a lock hole.

Description

technical field [0001] The invention relates to a door lock system. Background technique [0002] Household anti-theft doors or community unit doors generally adopt a traditional key and door lock switch system. A bunch of keys, people often need to carefully find the corresponding one, and then align the keyhole to open the door; and this series of behaviors will be more difficult when the light source is insufficient. In winter nights, the cold wind blows outside the door, The delay in unlocking the door is particularly long. Contents of the invention [0003] The purpose of the present invention is to provide a key with a proximity switch that is used together with a door lock with a permanent magnet, so that people can quickly find the position of the lock hole and the corresponding key when the light source is insufficient. The technical solution is as follows: [0004] A key with a proximity switch, including a key body and a key handle, is characterized in that a...
