Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

As shown in fig. 1 to 5, a suspension type key includes: the upper cover 1, the middle shaft 2 and the lower cover 3; the method is characterized in that: a channel hole which is in accordance with the outline of the upper part of the guide core 2 is formed in the center of the upper cover 1, the upper end of the guide core 2 is inserted into the channel hole of the upper cover 1 from the lower part, a round shaft 21 is arranged below the guide core 2, and a first magnetic device 22 is arranged in the round shaft 21; the center of the lower cover 3 is provided with a shaft hole 31, the round shaft 21 of the guide core 2 is inserted into the shaft hole 31 of the lower cover 3, and a second magnetic device 32 is arranged in the shaft hole 31 of the lower cover 3; the magnetic poles of the first magnetic device 22 and the magnetic poles of the second magnetic device 32 are arranged in the same polarity; the upper cover 1 and the lower cover 3 are connected into a key through a buckle structure, and the key limits the guide core 2 between the upper cover 1 and the lower cover 3.

Preferably, the magnetic poles of the first magnetic device 22 and the second magnetic device 32 are arranged in opposite homopolar manner; and the magnetic poles are preferably arranged in a manner that S poles are opposite to each other, the guide core 2 ascends under the action of repulsive magnetic force and is limited in the key by the upper cover under normal conditions, and the guide core 2 descends under the action of external force to complete key operation.

Preferably, the circular shaft 21 of the guide core 2 is installed in the shaft hole 31 of the lower cover 3, and the circular shaft 21 of the guide core 2 is moved up and down along the shaft hole 32 of the lower cover 3.
