Lockset, profile lock and three-part window

Abstract

The invention relates to the technical field of a lockset, in particular to the lockset, a profile lock and a three-part window. The lockset provided by the invention comprises a lock cap, a base, a clamping component and a clamping fitting piece; a spring seat and a supporting seat are arranged on the base; a first spring slot is formed in the spring seat; a second spring slot is formed on the clamping fitting part; a reset spring is installed between the first spring slot and the second spring slot; a clamping slot is formed on the clamping fitting part; the clamping component is provided with a clamping portion; one end of the clamping component is provided with a button; and the other end of the clamping component is provided with a hook part. According to the lockset and the profile lock provided by the invention, the clamping component and the clamping fitting part are matched with each other in use, so the lockset and the profile lock are convenient to use, easy to operate, reasonable in structural design, convenient to mount and dismount and good in stability; the lockset has no possibility to damage the integrity of a profile when being applied to the profile, can be replaced many times without damaging the profile, is easy to open and close and convenient to use, and has certain economic values.

Description

technical field [0001] The invention relates to the technical field of locks, in particular to a window lock, in particular to a lock, a profile lock and a three-opening window with a profile lock. Background technique [0002] At present, most doors and windows are made of profiles represented by aluminum profiles. Therefore, the window sash (or door leaf) that is used to carry out profile preparation and window frame (or door frame) is connected or the profile lock piece that is fixed is popularized in a large number. The lifting type window that existing aluminum section bar prepares generally all is to install lock core and other parts with screw after drilling on section bar, also will perforate on section bar because of the needs of locking. [0003] However, drilling or opening holes on the profile will destroy the integrity of the profile. Not only is installation troublesome, time-consuming and labor-intensive, it is prone to failure after long-term use, and it is ...

Problems solved by technology

[0003] However, drilling or opening holes on the profile will destroy the integrity of the profile. Not only is installation troublesome, time-consuming and labor-intensive, it is prone to failure after long-term use, and it is even more troublesome to replace the lock after it is broken. Tools must be used for disassembly and assembly. The process is slow, time-consuming, cumbersome to operate, and inconvenient to open and close the lock

In addition, since the lock cylinder and the hole are used together, when the screw hole that has been drilled once on the profile can no longer be used, it is difficult to replace a lock at another position of the profile, which often cannot be reused. It is necessary to replace the entire profile, resulting in waste, which is almost equivalent to one-time use, especially for household windows, which is very inconvenient, wastes resources, and brings a certain economic burden
