Background

The lock core is a main part for controlling the opening of the lock, the lock core is used for controlling the operation of a lock body, the lock body is responsible for opening and locking doors and windows, the key function is to transmit torsion by the head, and other parts of the lock are driven to achieve the purposes of unlocking and locking. The types of lock cylinders are various, and the modes of transmitting torsion are different although the structures are different, but the functions are the same.

As shown in fig. 6, the lock cylinder is installed on the door frame by using two bolts, namely an upper bolt and a lower bolt, which is not attractive due to the existence of the bolts.

Disclosure of Invention

In order to overcome the defects in the prior art, the utility model provides a lock cylinder mounting structure which avoids screws in threaded connection with a door leaf frame.

In order to achieve the above purpose, the utility model provides a lock cylinder mounting structure, which comprises an outward-stretching assembly arranged on the side surface of a lock cylinder body, wherein when the lock cylinder body is arranged in a mounting hole of a door leaf frame, the outward-stretching assembly is outwards stretched and pressed on the mounting hole so as to mount the lock cylinder body on the door leaf frame.

Preferably, the flaring component comprises an outer pressing piece in threaded connection with the lock cylinder body, a fixing piece is arranged on one side of the outer pressing piece, one end of the fixing piece is rotationally connected with the lock cylinder body, an outer conical surface used for pressing one side of the fixing piece is arranged at the end part of the outer pressing piece, and when the outer pressing piece rotates in the lock cylinder body, the outer conical surface pushes the fixing piece to rotate, so that the other end of the fixing piece is outwards opened and pressed on the mounting hole.

Preferably, one side of the fixing member has an inclined surface, and the fixing member is pressed against the mounting hole by the inclined surface when being opened outward.

Preferably, the two opposite sides of the lock core body are provided with the flaring components.

Preferably, both sides of the outer pressing piece are provided with fixing pieces.

The utility model has the technical effects and advantages that:

1. the lock core body is arranged on the door leaf frame in a pressing mode by adopting the outward opening mode of the outward opening component, so that the screw connected with the door leaf frame in a screwed mode is avoided, the screw is not observed outside, and the lock core is more attractive and is not easy to damage.

Detailed Description

Examples

As shown in fig. 1 to 5, the present embodiment provides a lock cylinder mounting structure, which includes a flared assembly 2 mounted on a side surface of a lock cylinder body 1, and when the lock cylinder body 1 is mounted in a mounting hole 201 of a door frame 200, the flared assembly 2 is flared and pressed against the mounting hole 201, so that the lock cylinder body 1 is mounted on the door frame 200.

By adopting the outward opening mode of the flaring component 2 to press on the mounting hole 201, the lock cylinder body 1 can be mounted on the door leaf frame 200, screws screwed with the door leaf frame 200 are avoided, and the screws are not observed outside, so that the lock cylinder is more attractive and is not easy to damage.

Specifically, as shown in fig. 1 to 5, the flaring assembly 2 includes a flaring member 22 screwed with the cylinder body 1, a fixing member 21 provided at one side of the flaring member 22 and having one end rotatably connected with the cylinder body 1, and an end portion of the flaring member 22 has an outer tapered surface 221 for pressing one side of the fixing member 21, and when the flaring member 22 is rotated into the cylinder body 1, the outer tapered surface 221 presses the fixing member 21 to rotate, thereby causing the other end of the fixing member 21 to be flared outwardly and pressed against the mounting hole 201. One end of the fixing member 21 may be movably riveted to the lock cylinder body 1 by means of a rivet 23, so that the fixing member 21 may rotate around the riveting point. Wherein, the outer pressing piece 22 can use an inner hexagonal countersunk head screw, the head part of the outer pressing piece has an outer conical surface, and the outer pressing piece can play a role in pushing the fixing piece 21 to rotate during rotation. Further, in order to improve the stability of installation, the flared assemblies 2 are provided on both opposite sides of the lock cylinder body 1, and further, in order to further improve the stability of installation, the fixing members 21 are provided on both sides of the flared member 22.

Specifically, as shown in fig. 3, one side of the fixing member 21 has a slope 211, and the fixing member 21 is pressed against the mounting hole 201 by the slope 211 when it is opened outward.

The installation operation process comprises the following steps: during installation, as shown in fig. 1 and 2, one end of the lock core body 1 is placed in the installation hole 201, then the outer pressing piece 22 is screwed, the outer pressing piece 22 pushes the fixing piece 21 to open outwards through the outer conical surface 221, and the installation hole 201 is propped against, so that the lock core body 1 is fixed on the door leaf frame 200, namely, the installation is completed, and the operation is simpler.
