Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-3, the present utility model provides a technical solution: the utility model provides a normally open structure of electric lock, including ejector pin box 1, go up separation and reunion 2, down separation and reunion 3, ejector pin box switch 4, automatically controlled mainboard 5 and handle 6, the internal face of ejector pin box 1 is connected with ejector pin 1.1, go up separation and reunion 2 setting and be connected at the lower extreme of ejector pin box 1, lower separation and reunion 3 is connected with last separation and reunion 2, ejector pin box switch 4 sets up at the lower extreme of last separation and reunion 2 and lower separation and reunion 3, automatically controlled mainboard 5 sets up the lower extreme at ejector pin box switch 4, handle 6 is connected with lower separation and reunion 3, the outer wall cover of handle 6 is equipped with handle torsional spring 6.1.

In this embodiment, preferably, the lower clutch 3 is internally provided with a lower clutch switch contact 3.1 and a clutch bolt bayonet 3.2 in sequence, the clutch bolt bayonet 3.2 is arranged at the inner side of the lower clutch switch contact 3.1, the clutch switch contact 3.1 is interacted with the ejector rod box switch 4 through the handle 6 to control the retraction of the ejector rod 1.1, the clutch switch contacts 3.1 are not less than two, the clutch switch contacts 3.1 can be in contact or induction type, can be integrally formed and can also be independently installed, and the purpose of locking can be achieved by lifting the handle 6, and the lower clutch switch contact 3.1 and the clutch switch are induced to achieve the purpose of locking the handle 6.

In this embodiment, preferably, the clutch bolt 2.2 and the clutch bolt spring 2.3 are sequentially arranged in the upper clutch 2, the clutch bolt spring 2.3 is sleeved on the outer wall surface of the clutch bolt 2.2, and the push rod box switch 4 mainly controls the retraction of the push rod 1.1, wherein the push rod box switch 4 can adopt a contact type or an induction type; the ejector rod box switch 4 can be of a single independent structure or can be combined with the electric control main board 5 into a single main body, and the arrangement position of the ejector rod box switch 4 is not limited in the direction of the lower clutch 3.

The working principle and the using flow of the utility model are as follows: when unlocking, the electric control main board 5 receives a corresponding unlocking instruction, so as to control the ejector rod box 1 to eject the ejector rod 1.1; the ejector rod 1.1 pushes the clutch bolt 2.2 into the lower clutch bolt bayonet 3.2, and at the moment, the upper clutch and the lower clutch form a combination body under the action of the clutch bolt 2.2; therefore, the handle 6 is pressed down to drive the upper clutch 2 to rotate so as to realize unlocking (door opening), and when the door is closed, the handle 6 is restored to the horizontal direction under the action of the handle torsion spring 6.1; at the moment, the upper clutch and the lower clutch are positioned at the connecting assembly, namely the lockset is positioned at the unlocking body; the door is opened again or for many times without the need of the electric control main board 5 to receive an unlocking instruction, so that the aim of normally opening is fulfilled, and when the handle 6 is lifted upwards to drive the upper clutch and the lower clutch to rotate in the opposite direction of unlocking; after rotating for a certain angle, the lower clutch switch contact 3.1 acts with the push rod box 1 switch; the switch of the ejector rod box 1 transmits locking information to the electric control main board 5, so that the ejector rod box 1 is controlled to retract the ejector rod 1.1 to the locking position; the clutch bolt 2.2 is withdrawn from the lower clutch bolt bayonet 3.2 under the action of the elasticity of the clutch bolt spring 2.3, and the upper clutch and the lower clutch are in free bodies so as to achieve the locking purpose; the handle 6 is restored to the horizontal direction under the action of the handle torsion spring 6.1, and the handle 6 cannot be unlocked when the handle 6 is pressed down; the purpose of normally opening can be achieved only by inputting a corresponding unlocking command again.

The foregoing is only a preferred embodiment of the present utility model, but the scope of the present utility model is not limited thereto, and any person skilled in the art, who is within the scope of the present utility model, should make equivalent substitutions or modifications according to the technical scheme of the present utility model and the inventive concept thereof, and should be covered by the scope of the present utility model.
