Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings.
As shown in fig. 1 to 5, a limiting structure capable of limiting an angle comprises a window frame 1, wherein a window sash 11 is arranged on the window frame 1, a foldable hinge assembly 10 is arranged between the window sash 11 and the window frame 1, a sliding groove 15 is formed in the window frame 1 along the width direction of the window frame, a sliding seat 20 is slidably arranged in the sliding groove 15, the hinge assembly 10 comprises a connecting rod piece rotationally connected with the sliding seat 20, and the sliding seat 20 slides back and forth along the sliding groove 15 to adjust the opening angle of the window sash 11; the link member is divided into a first link 12, a second link 13, and a third link 14.
The first connecting rod 12 is movably arranged between the window sash 11 and the sliding groove 15, and two ends of the first connecting rod 12 are movably connected through a rotating shaft 29, so that the two ends of the first connecting rod 12 can rotate; the second connecting rod 13 is movably installed between the first connecting rod 12 and the sliding seat 20, two ends of the second connecting rod 13 are movably connected through a rotating shaft 29, two ends of the second connecting rod 13 are rotatable, the third connecting rod 14 is movably installed between the window sash 11 and the sliding seat 20, two ends of the third connecting rod 14 are movably connected through the rotating shaft 29, and two ends of the third connecting rod 14 are rotatable.
Preferably, one end of the second connecting rod 13 is rotatably mounted at the middle end of the first connecting rod 12 through a rotating shaft 29, and when the sliding seat 20 slides along the sliding groove 15, the first connecting rod 12, the second connecting rod 13 and the third connecting rod 14 correspondingly realize unfolding or folding, and the larger the unfolding angle is, the larger the unfolding angle of the fan window is; conversely, the smaller the angle at which the first link 12, the second link 13, and the third link 14 are deployed, the smaller the angle at which the window fan is deployed.
The sliding groove 15 is provided with a fixed bottom plate 16, the bottom plate 16 is provided with a sliding groove 17 for sliding the sliding seat 20, the sliding groove 17 is provided with a first connecting hole 291 and a second connecting hole 292 for installing the rotating shaft 29 at the tail end of the first connecting rod 12, and when the hinge assembly 10 is connected with the window sash 11, the corresponding first connecting hole 291 or second connecting hole 292 is selected. The sliding seat 20 slides along the sliding groove 17 when sliding, the sliding groove 15 of the window frame 1 is not damaged, the sliding groove 15 is effectively protected, and the sliding groove 17 of the bottom plate 16 can be replaced after being damaged.
A baffle 18 is also formed in the window frame 1 in parallel with the sliding groove 15 along the width direction, and the baffle 18 is positioned at the edge of the sliding groove 15 and can be used for supporting the window sash 11, so that the window sash 11 cannot move towards the inner side of the window frame 1 when being closed.
The limiting block 2 used for propping against the sliding seat 20 is arranged in the sliding groove 17 of the bottom plate 16, the stop seat 19 is arranged at the other end of the sliding groove 17, and the limiting block 2 and the stop seat 19 prop against the two ends of the sliding seat 20, so that the sliding seat 20 cannot slide on the sliding groove 17 continuously, the opening angle can be controlled not to be too large, the function of better protecting the safety of a window can be achieved, and the window can continue to have a ventilation function.
The limiting block 2 is provided with a mounting component which is detachably connected with the sliding groove 17, the limiting block 2 is formed with a compression groove 23 which enables the limiting block 2 to elastically deform under the stress, and the limiting block 2 can be more conveniently placed into the sliding groove 17 of the window frame 1; . The limiting block 2 comprises a body block 21 detachably arranged on the sliding groove 17, an elastic block 22 is formed on the body block 21, and a gap between the body block 21 and the elastic block 22 is the compression groove 23. A gap exists between one end of the elastic block 22 and the elastic block 22.
In this embodiment, a compression groove 23 is formed between the body block 21 and the elastic block 22 as a gap, the sliding seat 20 is limited between the stop seat 19 and the limiting block 2, and the force acted by the elastic block 22 is different from the opening or closing force of the window, so that when the limiting block 2 is used for limiting the opening angle of the window, the stress surface of the window is smaller, and the safety of the window can be ensured; on the other hand, the requirements for parts are also smaller. If the opening angle of the part is too large, the component force in the splitting direction of the window is large, the sudden strong wind cannot be prevented, and on the other hand, the requirement on the supported part is also large, and the ageing degree of the part is also faster.
The outer side surface of the elastic block 22 is formed with an arc-shaped bulge 24 which is in contact with the side wall of the chute 17, the mounting assembly comprises a dismounting hole 25 formed in the elastic block 22, and when the limiting block 2 is dismounted by using a tool, the tool can be inserted into the dismounting hole 25 to serve as a tilting point, so that the limiting block 2 is dismounted and taken out.
Preferably, the cross-sectional shape of the detachment hole 25 may be square or rectangular.
The mounting assembly further comprises a top positioning hole 27 formed in the body block 21 and a bottom positioning hole 26 formed in the chute 17, and a positioning screw 28 is detachably mounted between the top positioning hole 27 and the bottom positioning hole 26, so that after the elastic block 22 is matched with the chute 17, the positioning screw 28 can be locked again, and double insurance is realized.
The chute 17 is formed with a limiting protrusion 293 capable of propping against one end of the limiting block 2, so that the other end of the limiting block 2 is propped against by the limiting protrusion 293, the installation stability of the limiting block 2 in the chute 17 is further improved, and the limiting block is not easy to shift.
The stopper 2 of this scheme is arranged in adding stopper to the spout 17 of window frame 1 in the angle of windowing of control casement 11, gets moreover and puts the convenience, can more effectually exert stopper 2's effect, when need dismantle, loosens the setting screw 28 and takes out now, later, prizes stopper 2's elastic block 22 gently, separates stopper 2 and spout 17, realizes dismantling fast.
In one embodiment, as shown in fig. 2, a stopper 2 is inserted into the chute 17 of the window frame 1 and locks the set screw 28 into the top and bottom set holes 27 and 26. As shown in fig. 3, the fully opened window can be closed to a certain angle as shown in fig. 4, the limiting block 2 is placed on the sliding groove 17, the dismounting hole 25 on the limiting block 2 is lightly pried, the limiting block 2 is plugged into the sliding groove 17 of the window frame 1, after no reverse installation is confirmed, the top positioning hole 27 and the bottom positioning hole 26 are aligned and the positioning screw 28 is locked, one end of the limiting block 2 abuts against the limiting protrusion 293, and the opening angle of the window sash 11 is changed from the angle shown in fig. 3 to the angle shown in fig. 5.
Conversely, if the stopper 2 is taken out, the set screw 28 is screwed out by the same screwdriver, and then the elastic block 22 of the stopper 2 is gently pried to take out the stopper 2, the opening angle of the window sash 11 is changed from the angle shown in fig. 5 to the angle shown in fig. 3.
In view of the above, the present invention has the above-mentioned excellent characteristics, so that it can be used to improve the performance and practicality of the prior art, and is a product with great practical value.
The foregoing is merely exemplary of the present invention, and those skilled in the art should not be considered as limiting the invention, since modifications may be made in the specific embodiments and application scope of the invention in light of the teachings of the present invention.
