Abstract
Description
Technical Field
[0001] The invention relates to the technical field of building hardware accessories, and in particular to a locking system for fireproof windows. Background Art
[0002] Many fireproof window locking devices on the market require milling of the window body before installation; the accessories are also stamped. After long-term use, the stamped parts are very easy to deform, which will cause the window to fail to close or open. Summary of the invention
[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and to provide a locking system for fireproof windows which has a novel structure and can be installed quickly without milling.
[0004] In order to achieve the above objectives, the technical solution adopted by the present invention is: a locking system for fireproof windows, comprising a lock seat component and a lock tongue component respectively installed on a fan profile and a frame profile; the lock seat component comprises a first connecting base for connecting the fan profile or the frame profile and a lock baffle for locking with the lock tongue component; a buckling portion for buckling with the fan profile or the frame profile is formed on one side of the first connecting base, and a torsion spring for buckling with the fan profile or the frame profile is provided on the other side of the first connecting base.
[0005] The beneficial effect of the present invention is that a torsion spring is arranged on the lock seat component of the present invention. When the lock seat component is installed and connected with the fan body profile or the frame body profile, the lock seat component is first rotated to the horizontal direction so that its buckling part can extend into the buckling groove of the profile, and then the lock seat component is rotated to the longitudinal direction as a whole so that the buckling part is buckled with the buckling groove of the profile. Then, the torsion spring is compressed to make it smoothly enter the buckling groove after being compressed and deformed, and finally, under the elastic action of the torsion spring itself, the torsion spring is restored to deform and buckled with the buckling groove. The above installation method is quick and simple, and can be installed and buckled by relying on the buckling groove of the profile itself, without the need to perform additional milling of the profile, which is convenient for installation and maintenance.
[0006] Preferably, the lock tongue component includes a second connection base for connecting to the fan body profile or the frame body profile, a telescopic lock tongue device arranged on the second connection base, and the telescopic lock tongue device includes a housing, a lock tongue arranged in the housing and telescopic relative to the housing, and a reset spring that drives the lock tongue to extend. When the door or window sash is closed, the lock tongue can cooperate with the lock catch baffle to lock the door or window sash, and at the same time, because the lock tongue has a telescopic function, when the lock tongue contacts the lock catch baffle during the closing process of the door or window sash, the lock tongue can be retracted to avoid so that the door or window sash can be closed smoothly without hindrance.
[0007] Preferably, the second connection base is provided with an adjustment slot extending parallel to the height direction of the fan body profile or the frame body profile, and the telescopic lock tongue device is slidably adjusted along the adjustment slot. The installation height of the telescopic lock tongue device can be adjusted by the adjustment slot to make it fit the position of the lock seat component.
[0008] Preferably, the housing comprises a panel and a lock tongue base, the panel is provided with a through hole for the lock tongue to extend and retract, and the lock tongue base is bent to form a concave structure for accommodating a lock tongue box reset spring.

DETAILED DESCRIPTION
[0017] The technical solution claimed by the present invention will now be further described in detail with reference to the accompanying drawings and specific embodiments.
[0018] See also Figures 1 to 7 As shown, a locking system for fireproof windows in this embodiment includes a lock tongue component 2 installed on the fan body profile and a lock seat component 1 installed on the frame body profile. In this embodiment, the lock tongue component 2 is also linked with the handle 3, and the lock seat handle 3 can drive the lock tongue component 2 to rise and fall.
[0019] In this embodiment, the lock base component 1 includes a first connection base 11 for connecting to a fan body profile or a frame body profile and a lock baffle 12 for locking with the lock tongue component 2. A buckle connection portion 111 for buckling with the fan body profile or the frame body profile is formed on one side of the first connection base 11, and a torsion spring 112 for buckling with the fan body profile or the frame body profile is provided on the other side of the first connection base 11.
[0020] In this embodiment, the lock tongue component 2 includes a second connection base 21 for connecting to a fan body profile or a frame body profile, and a telescopic lock tongue device 22 arranged on the second connection base 21. The second connection base 21 is provided with an adjustment slot 211 extending parallel to the height direction of the fan body profile or the frame body profile, and the telescopic lock tongue device 22 is slidably adjusted along the adjustment slot 211. The telescopic lock tongue device 22 includes a housing, a lock tongue 222 arranged in the housing and telescopic relative to the housing, and a reset spring 223 for driving the lock tongue 222 to extend. The housing includes a panel 2211 and a lock tongue base 2212, the panel 2211 is provided with a through hole for the lock tongue 222 to telescope through, and the lock tongue base 2212 is bent to form a concave structure for accommodating the lock tongue 222 and the reset spring 223.
[0021] The installation method of the lock base component 1 in this embodiment is as follows: first, the lock base component 1 is rotated to the horizontal direction so that its buckling portion 111 can extend into the buckling groove of the profile, and then the lock base component 1 is rotated as a whole to the longitudinal direction so that the buckling portion 111 is buckled with the buckling groove of the profile. Then, the torsion spring 112 is compressed to make it enter the buckling groove smoothly after being compressed and deformed, and finally, under the elastic action of the torsion spring 112 itself, the torsion spring 112 is restored to deform and buckled with the buckling groove.
[0022] In this embodiment, the locking is achieved as follows: when the door or window is closed, the lock tongue 222 can be locked with the lock baffle 12 to lock the door or window. At the same time, since the lock tongue 222 has a telescopic function, when the lock tongue 222 contacts the lock baffle 12 during the closing process of the door or window, the lock tongue 222 can be retracted to avoid the door or window so that the door or window can be closed smoothly without hindrance. When unlocking is required, the lock tongue component 2 can be lifted and lowered as a whole by operating the handle 3, so that the height positions of the lock base component 1 and the lock tongue component 2 are staggered. At this time, the lock base component 1 and the lock tongue component 2 are unfastened to achieve unlocking.
[0023] The embodiments described above are only preferred embodiments of the present invention and are not intended to limit the present invention in any form. Any technician familiar with the art can use the above disclosed technical content to make more possible changes and modifications to the technical solution of the present invention without departing from the scope of the technical solution of the present invention, or modify it into an equivalent embodiment of equivalent changes. Therefore, all equivalent and equivalent changes made according to the ideas of the present invention without departing from the content of the technical solution of the present invention should be included in the protection scope of the present invention.
