Detailed Description

To further explain the technical means and effects of the present invention adopted to achieve the predetermined objects, the following detailed description will be provided with reference to the accompanying drawings and preferred embodiments for describing specific embodiments, structures, features and effects thereof.

Referring to fig. 2 to 7, the glass door lock with an electronic lock cylinder 32 according to the first embodiment of the present invention includes a lock body 3, a U-shaped left lock beam 1 and a right lock beam 2, wherein the left lock beam 1 includes a first insert rod 11, a second insert rod 12 and a left connecting rod 13 for connecting the first insert rod 11 and the second insert rod 12 in parallel, and the right lock beam 2 includes a first accommodating tube 21 and a second accommodating tube 22 for accommodating the first insert rod 11 and the second insert rod 12, respectively, and a right connecting rod 23 for connecting the first accommodating tube 21 and the second accommodating tube 22.

The first inserted bar 11 and the second inserted bar 12 are inserted into the first accommodating pipe 21 and the second accommodating pipe 22 to be matched, so that the left lock beam 1 and the right lock beam 2 form a closed ring; the middle part of the first insert rod 11 is provided with a locking notch 110, and the right end of the first accommodating tube 21 is provided with a through hole corresponding to the locking notch 110. The first insert pin 11 has a circular cross section, and the first insert pin 11 is rotatable within the first accommodation tube 21. The first accommodating tube 21 is longer than the second accommodating tube 22.

The right connecting rod 23 and the left connecting rod 13 are externally fixed with

anti-slip layers

10 and 20 for increasing friction force.

The right end of the first inserted bar 11 that is preferred is fixed with the protruding stupefied of preventing falling, and first holding pipe 21 is fixed with the protruding stupefied of anti-falling cooperation on the right side of lock tongue 34, and the protruding stupefied of anti-falling protruding and anti-falling cooperation is used for preventing first inserted bar 11 from holding the interior roll-off of pipe 21.

The lock body 3 is fixed at the left end of the first accommodating tube 21, and the lock body 3 includes an electronic key cylinder 32 and a locking tongue 34 accommodated in a housing 31, the electronic key cylinder 32 being used to drive the locking tongue 34 to engage or disengage the locking notch 110.

The electronic lock cylinder 32, whose axis of rotation is parallel to the axis of the first containing tube 21, comprises: the locking bolt 30 is fixed with a transmission rod 301 at one side of the cam 320, which is opposite to the first containing pipe 11, and the cam 320 is used for pressing the transmission rod 301 to move the locking bolt 30, which is opposite to the first containing pipe 21.

The lock body 3 further comprises a limiting rod 33 perpendicular to the first accommodating tube 21, the locking bolt 30 is provided with an anti-backward-movement notch 300 capable of accommodating part of the limiting rod 11, the limiting rod 33 is provided with a matching notch 330 capable of accommodating part of the locking bolt 30, when the locking bolt 30 is meshed with the locking notch 110, the matching notch 330 corresponds to the anti-backward-movement notch 300, and at this time, the locking bolt 30 can move perpendicular to the first accommodating tube 21. A compression spring is provided between the end of locking bolt 34 facing away from first receptacle 21 and the housing, and the compression spring can compress locking bolt 30 to engage locking notch 110 when the motor is not operating.

The preferred mating notch 330 corresponds to the anti-backup notch 300, with the end of the stop bar abutting the housing.

It is of course possible to control the angle of rotation of the motor to control whether the convex or concave portion of cam 320 is directed towards drive rod 301, but this precise control is very costly.

When the locking bolt 30 is completely separated from the locking notch 110, the anti-reverse notch 300 corresponds to the left position of the matching notch 330 of the limiting rod 33, at this time, the limiting rod can move along the first accommodating tube 21, at this time, the button can be pulled out to correspond the parts of the two sides of the matching notch 330 to the anti-reverse notch, and thus, the locking bolt can keep the position. Preferably, a compression spring is provided between the end of the limiting rod 33 opposite to the button 331 and the lock housing 31, and the compression spring can provide power for the movement of the limiting rod.

Preferably when locking is required, the user is required to press the button until it abuts the housing, causing the bolt to move towards the first containing tube under the bias of the spring.

In this embodiment, the anti-backup notch 300 is an L-shaped cavity.

Referring to fig. 10, the anti-falling notch 300 in this embodiment is a rectangular parallelepiped cavity.

Although the present invention has been described with reference to the preferred embodiments, it should be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the present invention.
