Description

Technical Field

[0001] The invention relates to the technical field of building hardware accessories, in particular to a casement window gap ventilation component. Background Art

[0002] Accidents of children falling or getting stuck after climbing out of windows happen from time to time. This is because the windows of many homes can only be opened sideways and do not have gap ventilation function. Even if there are windows with gap ventilation function, they do not have child locks, and the use of multi-link connections can easily cause the connecting rods to deform, affecting the use of the hardware system. Summary of the invention

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a casement window gap ventilation component with a novel and stable structure and a child lock function.

[0004] In order to achieve the above objectives, the technical solution adopted by the present invention is: a casement window gap ventilation component, including a slide groove assembly and a pull rod assembly respectively arranged on the window sash and the window frame; the slide groove assembly includes a slide groove seat and a lock seat slidably connected to the slide groove seat, the lock seat is provided with a lock groove extending parallel to the sliding direction of the lock seat, and the side wall of the lock groove is provided with a notch; the lock seat is provided with a locking mechanism, and the slide groove seat is provided with a locking structure cooperating with the locking mechanism; the pull rod assembly includes a pull rod seat and a pull rod hinged on the pull rod seat, a locking block is provided on the free end of the pull rod, the locking block is slidably matched with the locking groove, and when the locking mechanism and the locking structure are unlocked, the notch is aligned with the locking block to allow the window sash to open and close freely.

[0005] The beneficial effects of the present invention are as follows: the casement window gap ventilation component of the present invention has both ventilation and child lock functions, allowing the window sash to be freely opened to a certain angle to meet the ventilation effect, and also preventing children from opening the window sash to a larger angle without authorization to cause a falling accident, and its operation is simple and the structure is reliable. Specifically, the slide assembly or the pull rod assembly can be operated by other components such as a handle to slide and adjust, and when the locking mechanism and the locking structure of the slide assembly cooperate to lock, the locking block on the pull rod assembly is in the locking groove, and when the window sash is opened, the locking block slides in the locking groove, and the pull rod swings with the opening of the window sash. Due to the limited length of the pull rod, the window sash can only be opened to a certain angle, and the ventilation needs can be met at this time. After unlocking the locking mechanism and the locking structure, the locking block on the pull rod is aligned with the notch of the lock groove, and when the window sash is opened, the locking block can be disengaged from the lock groove through the notch, and at this time the window sash can be freely opened to the maximum angle and is no longer limited by the pull rod.

[0006] Preferably, the locking mechanism includes a lock buckle pivotally connected to the lock seat and a first elastic member driving the lock buckle to reset, and the locking structure is a buckle groove formed on the slide groove assembly. The lock buckle and the buckle groove can be matched and buckled to achieve mutual locking between the locking structures.

[0007] Preferably, a pressing portion is formed on the latch. The pressing portion can facilitate the user to press the latch so that it is disengaged from the buckle groove to unlock.

[0008] Preferably, the tie rod assembly further includes a second elastic member for driving the tie rod to reset.

[0009] Preferably, a positioning member is provided on the chute assembly. When the lock base abuts against the positioning member, the notch is aligned with the lock block. The positioning member can be used to accurately move the lock base to the corresponding position so that the notch is aligned with the lock block to achieve unlocking. Description of the Drawings

Detailed Description of the Invention

[0021] The technical solution claimed in the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0022] See Figures 1 to 10 As shown, a gap ventilation component for a casement window in this embodiment includes a chute assembly 1 provided on the window frame 4 and a pull rod assembly 2 provided on the window sash 3.

[0023] The chute assembly 1 includes a chute base 11 fixedly installed on the inner side of the window frame 4 and a lock base 12 slidably connected to the chute base 11. A lock groove 121 extending parallel to the sliding direction of the lock base 12 is formed on the lock base 12, and a notch 122 is formed on the side wall of the lock groove 121. The lock base 12 is provided with a locking mechanism, and a locking structure 111 cooperating with the locking mechanism is provided on the chute base 11. In this embodiment, the locking mechanism includes a lock catch 1231 pivotally connected to the lock base 12 and a first elastic member 1232 for driving the lock catch 1231 to reset. In this embodiment, the first elastic member 1232 is a conical spring. A pressing portion 1233 is formed on the lock catch 1231, and the pressing portion 1233 facilitates the user to press the lock catch 1231 to disengage it from the buckle groove for unlocking. The locking structure 111 is a buckle groove formed on the chute assembly 1. The lock catch 1231 and the buckle groove can be cooperatively buckled to realize the mutual locking between the locking structure 111 and the locking structure 111.

[0024] The pull rod assembly 2 includes a pull rod base 22, a pull rod 21 hinged to the pull rod base 22, and a second elastic member 23 for driving the pull rod 21 to reset. In this embodiment, the pull rod base 22 is slidably connected to the inner side of the window sash 3 and is linked with the handle. By operating the handle, the pull rod base 22 can be driven to slide and adjust along the inner side of the window sash 3. A lock block 211 is provided at the free end of the pull rod 21. The lock block 211 is slidably matched with the lock groove 121. And when the locking mechanism is unlocked from the locking structure 111, the notch 122 is aligned with the lock block 211 to enable the window sash 3 to open and close freely. The second elastic member 23 is a torsion spring, which can drive the pull rod 21 to reset and swing back into the lock groove 121. In this embodiment, a positioning member 112 is provided on the chute assembly 1. When the lock base 12 abuts against the positioning member 112, the notch 122 is aligned with the lock block 211. The positioning member 112 can be used to accurately move the lock base 12 to the corresponding position so that the notch 122 is aligned with the lock block 211 to realize unlocking.

[0025] The working principle of the gap ventilation component for the casement window in this embodiment is as follows:

[0026] See Figure 6 As shown, when the window sash 3 is closed, the handle is in the locked state, and at this time, the lock block 211 is in the lock groove 121.

[0027] See Figure 7 As shown, when it is necessary to open the window sash 3 for ventilation, the handle is first rotated 90 degrees and then in the open state. At this time, the pull rod assembly 2 is driven by the handle and moves downward as a whole. At this time, the lock block 211 on the pull rod 21 is still in the lock groove 121; See Figure 8 As shown, then when the window sash 3 is opened, the lock block 211 slides in the lock groove 121, and at the same time the pull rod 21 swings as the window sash 3 is opened. Since the length of the pull rod 21 is limited, the window sash 3 can only be opened at a certain angle, which can meet the ventilation requirements at this time.

[0028] See Figure 9 As shown, when it is necessary to further open the window sash 3 to the maximum angle, first press the pressing part 1233 on the lock catch 1231 to release the lock catch 1231 from the buckle groove, and the lock seat 12 slides downward along the sliding groove seat 11 and abuts against the positioning part 112. See Figure 10 As shown, then close the window sash 3 and reset it so that the handle is in the open state. After the window sash 3 is closed, the lock block 211 on the pull rod 21 is aligned with the notch 122 on the lock groove 121. At this time, the window sash 3 can be freely opened to the maximum angle without being restricted by the length of the pull rod 21.

[0029] When the window sash 3 is closed again, the lock block 211 returns from the notch 122 to the lock groove 121. Then the handle is reset to the locked state. At this time, the pull rod assembly 2 is driven by the handle and moves upward as a whole, and at the same time the lock block 211 jacks up the lock seat 12 in the lock groove 121, so that the lock catch 1231 is buckled and reset with the buckle groove again.

[0030] The above-described embodiments are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Any person skilled in the art can make more possible changes and modifications to the technical solution of the present invention, or modify it into an equivalent embodiment with equivalent changes, without departing from the scope of the technical solution of the present invention. Therefore, all equivalent changes made according to the idea of the present invention without departing from the content of the technical solution of the present invention should be covered by the protection scope of the present invention.
