Description

Technical Field

[0001] The invention relates to the technical field of building hardware, in particular to a component for casement windows with switchable gap ventilation and a child lock function. Background Art

[0002] Accidents of children falling or getting stuck after climbing through windows often occur because the windows of many families can only be opened sideways and do not include gap ventilation function. Even if there is a gap ventilation function, it does not have a child lock switch. Many gap ventilation parts on the market require processing of the window body before installation, and window processing will affect the air tightness, sound insulation and heat insulation of the window. In view of the above problems, it is particularly important to add a child lock switch to the gap ventilation of the casement window to protect the window sash from damage and ensure personal safety. Summary of the invention

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and to provide a component with a novel structure, a child-proof opening function, a safe and reliable switchable gap ventilation component for casement windows and a child lock function.

[0004] In order to achieve the above purpose, the technical solution adopted by the present invention is: a component with switchable gap ventilation and child lock function for casement windows, including a first component and a second component respectively installed on the window sash and the window frame; the first component includes a base and a connecting rod hinged on the base, a locking nail is arranged on the free end of the connecting rod, and the base is equipped with a driving mechanism for driving it to move and switch between a first position and a second position; the second component includes a slide groove seat, a first slider and a second slider slidably connected to the slide groove seat and distributed up and down; the first slider moves and switches between a third position and a fourth position along the slide groove seat; the first slider The block is formed with an upper limit portion and a lower limit portion, and a gap for a locking pin to pass through is reserved between the upper limit portion and the lower limit portion; the second slider is provided with a slide groove extending in the up-down direction, and the slide groove is provided with a notch for a locking pin to pass through on the same side of the first slider; when the base moves to the first position and the first slider moves to the third position, the locking pin is aligned with the gap between the upper limit portion and the lower limit portion; when the base moves to the first position and the first slider moves to the fourth position, the locking pin is aligned with the upper limit portion; when the base moves to the second position and the first slider moves to the third position, a gap for a locking pin to pass through is reserved between the first slider and the second slider.

[0005] The intentional effect of the present invention is that the first component and the second component in the present invention can be installed on the first component and the second component respectively. And the second component has a first slider that can be slidably adjusted, and the base on the first component can also be controlled by the driving mechanism to switch between the first position and the second position. In the process of opening the window sash, the base will switch from the second position to the first position. At this time, if the first slider is in the third position, the locking pin is aligned with the gap between the upper limit part and the lower limit part, and the window sash can be opened freely without being restricted by the connecting rod. If the first slider is in the fourth position, due to the limiting effect of the upper limit part on the locking pin, during the process of opening the window sash, the locking pin will move in the direction of the second slider and finally move into the chute of the second slider. When the locking pin moves to the end of the travel of the chute, the window sash cannot be opened further due to the restriction of the connecting rod, thereby limiting the opening angle of the window sash. Since its operation process is relatively complicated, it can limit children from opening the window sash freely, thereby achieving a safety effect.

[0006] Preferably, two positioning concave points are reserved on the surface of the slide seat, and the two positioning concave points correspond to the third position and the fourth position of the first slider, respectively, and the first slider is provided with positioning beads that cooperate with the positioning concave points for positioning. When the first slider slides to the third position and the fourth position, respectively, the positioning beads can cooperate with the corresponding positioning concave points for positioning, so that the first slider needs to be pushed out from the third position and the fourth position with a greater force, thereby achieving a child safety effect.

[0007] Preferably, the second component is provided with a spring for driving the second slider to slide in the direction of the first slider. The spring can buffer the impact of the locking pin on the second component, avoiding collision damage of the locking pin during long-term use, thereby improving the durability of the product.

[0008] Preferably, the first component is provided with a reset torsion spring for driving the connecting rod to swing in the direction of closing the window sash. The reset torsion spring can keep the connecting rod in a closed state of the window sash in a natural state, ensuring normal use.

[0009] Preferably, a limit stopper is provided on the side of the base, and the limit stopper can be used to limit the connecting rod from swinging in a specified direction.

[0010] Preferably, the first sliding block is provided with anti-skid patterns on its side, so that the user can easily drive the first sliding block to slide. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The technical solution claimed by the present invention will now be further described in detail with reference to the accompanying drawings and specific embodiments.

[0026] See also Figures 1 to 6As shown, a component with switchable gap ventilation and child lock function for a casement window in this embodiment includes a first component 1 and a second component 2 respectively installed on the window sash and the window frame. In this embodiment, the first component 1 is installed on the window sash, and the second component 2 is installed on the window frame.

[0027] The first component 1 includes a base 11, a connecting rod 12 hinged on the base 11, and a reset torsion spring 14 for driving the connecting rod 12 to swing in the direction of closing the window sash. A locking pin 13 is provided on the free end of the connecting rod 12, and the base 11 is provided with a driving mechanism for driving it to move and switch between the first position and the second position. In this embodiment, the driving mechanism includes a handle and a linkage rod driven by the handle. The base 11 is fixedly mounted on the linkage rod and is driven by the handle to move in the up and down direction to move and switch between the first position and the second position. A limit stopper 111 is provided on the side of the base 11, and the limit stopper 111 can be used to limit the connecting rod 12 from swinging in a specified direction.

[0028] The second component 2 includes a slide seat 21, a first slider 22 and a second slider 23 which are slidably connected to the slide seat 21 and are arranged vertically; the first slider 22 moves and switches between the third position and the fourth position along the slide seat 21; in this embodiment, two positioning concave points 211 are reserved on the surface of the slide seat 21, and the two positioning concave points 211 correspond to the third position and the fourth position of the first slider 22, respectively, and the first slider 22 is provided with positioning beads 224 which cooperate with the positioning concave points 211 for positioning. When the first slider 22 slides to the third position and the fourth position respectively, its positioning beads 224 can cooperate with the corresponding fixed concave points for positioning, so that the first slider 22 needs to be pushed out from the third position and the fourth position with a greater force, so as to achieve the effect of child safety. In addition, the side of the first slider 22 is provided with anti-slip grooves, which can facilitate the user to drive the first slider 22 to slide.

[0029] The first slider 22 is formed with an upper limit portion 221 and a lower limit portion 222, and a gap 223 is left between the upper limit portion 221 and the lower limit portion 222 for the locking pin 13 to pass through; the second slider 23 is provided with a slide groove 231 extending in the up-down direction, and the slide groove 231 is provided with a notch 232 for the locking pin 13 to pass through on the same side of the first slider 22.

[0030] When the base 11 moves to the first position and the first slider 22 moves to the third position, the locking pin 13 is aligned with the gap 223 between the upper limit portion 221 and the lower limit portion 222. When the base 11 moves to the first position and the first slider 22 moves to the fourth position, the locking pin 13 is aligned with the upper limit portion 221. When the base 11 moves to the second position and the first slider 22 moves to the third position, a gap is left between the first slider 22 and the second slider 23 for the locking pin 13 to pass through.

[0031] See also Figures 7 to 13 As shown, in this embodiment, since the handle is also linked with the locking structure of the window sash, the base 11 will inevitably move from the second position to the first position during the opening of the window sash. When the first slider 22 is at the third position, the child lock is released. Since the locking pin 13 is aligned with the notch 223 between the upper limit portion 221 and the lower limit portion 222, the window sash can be opened freely without restriction. When the first slider 22 is at the fourth position, the child lock is locked. Due to the limiting effect of the upper limit portion 221 on the locking pin 13, during the opening of the window sash, the locking pin 13 will move in the direction of the second slider 23 and finally move into the chute 231 of the second slider 23. When the locking pin 13 moves to the end of the travel of the chute 231, the window sash cannot be opened further due to the restriction of the connecting rod 12, thereby limiting the opening angle of the window sash. Since its operation process is relatively complicated, it can limit children from opening the window sash freely, thereby achieving a safety effect.

[0032] 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.
