Description

Technical Field

[0001] The invention relates to the technical field of building hardware materials, and in particular to an automatic locking device for a curtain wall. Background Art

[0002] Hanging windows on existing curtain walls are widely used. Usually, hanging windows on curtain walls are equipped with hanging window sliding supports and supports (friction type and locking type) to realize the opening, positioning and closing of window sashes. In high-rise buildings or strong wind environments, hanging windows on curtain walls are subject to the combined effects of positive and negative wind pressures, which may damage the supports, causing the self-positioning of the window sash to fail, causing the window sash to repeatedly collide with the window frame, and posing a safety hazard of window sash damage and falling off. Summary of the invention

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a curtain wall automatic locking device with a novel structure.

[0004] In order to achieve the above purpose, the technical solution unique to the present invention is: an automatic locking device for a curtain wall, comprising a window sash lock seat component fixedly installed on the window sash of a hanging window and a window frame locking component fixedly installed on the window frame of the hanging window, the window frame locking component comprising a base, a locking tongue and a return spring for driving the locking tongue to automatically extend out from the surface of the base; the window sash lock seat component comprises a base and an adjusting block, wherein a pair of locking blocks are formed on the surface of the adjusting block to cooperate with the locking tongue for locking.

[0005] After the present invention adopts the above scheme, since the locking block on the window sash lock seat component and the locking tongue on the window frame locking component can cooperate with each other to lock, when the window sash of the hanging window is closed, the window sash lock seat component and the window frame locking component can cooperate to lock the window sash to the window frame to prevent the hanging window from being opened by wind pressure.

[0006] An adjustment installation in the inner and outer directions of the hanging window is formed between the base of the window sash lock seat component and the adjustment block, wherein a waist-shaped groove is reserved on the adjustment block, and a bolt hole is opened on the base, and the adjustment block and the base are connected by inner and outer adjustment bolts that pass through the waist-shaped groove and the bolt hole. After the present invention adopts the above structure, the installation position of the adjustment block on the base can be adjusted through the waist-shaped groove, and since the adjustment direction of the adjustment block corresponds to the inner and outer directions of the hanging window, on-site correction can be achieved through the above method.

[0007] The contact surfaces between the base and the adjustment block are formed with mutually matching positioning teeth, and the positioning teeth are arranged along the inner and outer sides of the hanging window. After the present invention adopts the above method, the positioning teeth between the base and the adjustment block can be mutually matched and clamped to further maintain the relative position of the two, thereby preventing the positions of the two from shifting during use.

[0008] The bottom surface of the base of the window sash lock seat component is provided with damping rubber. After the present invention adopts the above structure, the collision of the window sash lock seat component can be buffered.

[0009] The base of the window frame locking component is reserved with an installation cavity for accommodating a lock tongue and a reset spring, and the surface of the base is provided with an opening connected to the installation cavity and for the lock tongue to be extended and retracted, and the installation cavity is reserved with a cavity opening and a cover plate covering the cavity opening. After the present invention adopts the above structure, the lock tongue of the window frame locking component can be automatically ejected, thereby maintaining the locking.

[0010] The cover plate is connected to the installation cavity via bolts.

[0011] The base of the window frame locking component is formed with mounting parts on both sides, each of which is provided with a through hole for bolt connection with the hanging window frame, and height adjustment bolts are respectively threadedly connected to the mounting parts on both sides, and the height adjustment bolts press against the hanging window frame to adjust the installation height between the window frame locking component and the hanging window frame. After the present invention adopts the above structure, the installation height of the window frame locking component can be adjusted by the height adjustment bolts, thereby adjusting the installation height between the window frame locking component and the hanging window frame, and on-site correction can be achieved in the above manner.

[0024] The window frame locking component 2 includes a base 21, a lock tongue 22, and a reset spring 23 for driving the lock tongue 22 to automatically extend out of the surface of the base 21. The base 21 of the window frame locking component 2 is reserved with an installation cavity 211 for accommodating the lock tongue 22 and the reset spring 23. The surface of the base 21 is provided with an opening connected to the installation cavity 211 and for the lock tongue 22 to extend and retract. At the same time, the installation cavity 211 is reserved with a cavity opening and a cover plate 212 covering the cavity opening. The cover plate 212 is connected to the installation cavity 211 by bolts, and the lock tongue 22 of the window frame locking component 2 can be automatically popped out by the reset spring 23, thereby maintaining the lock. In addition, in this embodiment, mounting parts 24 are formed on both sides of the base 21 of the window frame locking component 2, and each mounting part 24 has a through hole for bolt connection with the hanging window frame. In addition, height adjustment bolts 25 are respectively threadedly connected to the mounting parts 24 on both sides, and the height adjustment bolts 25 press against the hanging window frame to adjust the installation height between the window frame locking component 2 and the hanging window frame. The installation height of the window frame locking component 2 can be adjusted by the height adjustment bolts 25, thereby adjusting the installation height between the window frame locking component 2 and the hanging window frame, and on-site correction can be achieved in the above manner.

[0025] The window sash lock seat component 1 includes a base 11 and an adjustment block 12, wherein a pair of locking blocks 121 are formed on the surface of the adjustment block 12 to lock with the lock tongue 22.
