Description

Technical Field

[0001] The utility model relates to the field of door and window hardware, in particular to an outward-opening bottom-hung inclined pull rod. Background Art

[0002] Existing household windows are basically divided into sliding windows, casement windows and hanging windows. Among them, hanging windows require the use of special hinges. However, when using, users often need the function of hanging windows to facilitate ventilation in rainy and snowy weather. On the other hand, because the angle between the hanging window and the fixed window frame after opening is too small, its ventilation efficiency is poor. Therefore, in actual use, it is often necessary to both hang and open and to achieve casement. Based on this demand, the "inward-opening and inward-tilting" type windows in the prior art often need to reinstall a sub-opening fan on the main opening fan. The main opening fan realizes the "inward tilting" action, that is, realizes the hanging open state, while the sub-opening fan realizes the casement opening action. This type of window is not only heavy overall and more complicated to install, but also actually integrates two sets of opening fans, which poses a greater challenge to the sealing of the window.

DETAILED DESCRIPTION

[0031] Below, the present invention is further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0032] Reference Figures 1-9 A downwardly suspended outward-opening inclined pull rod includes a trigger assembly 1, a casement assembly 2, and a suspension assembly 3. The trigger assembly 1 is disposed on the suspension assembly 3 and moves along the length of the suspension assembly 3. The casement assembly 2 is rotationally connected to one end of the suspension assembly 3. The trigger assembly 1, the suspension assembly 3, and the casement assembly 2 are arranged to overlap with each other, and the trigger assembly 1 and the suspension assembly 3 are connected by a rotating link 4. The trigger assembly 1 includes a trigger portion 11 and a hovering portion 12. The hovering portion 12 is disposed on the suspension assembly 3. The trigger portion 11 is disposed on the suspension assembly 3 and moves back and forth along the length of the suspension assembly 3. The hovering portion 12 is connected to the suspension assembly 3 by a rotating link 4. When the trigger portion 11 is in a first position, the trigger portion 11, the hovering portion 12, and the suspension assembly 3 overlap and lock with each other. When the trigger portion 11 is in a second position, the hovering portion 12 and the suspension assembly 3 rotate about the rotating link 4. The main function of the trigger portion 11 is to lock the suspension assembly 3 when the window is opened, preventing the suspension assembly 3 from moving. No matter what position the trigger portion 11 is in, the casement assembly 2 cannot be locked. The locking of the casement assembly 2 needs to be coordinated with the original lock buckle of the opening sash for locking, that is, the casement assembly 2 can be locked after the opening sash is locked with the original window frame, instead of relying on the trigger assembly 1 in this application for locking.

[0033] The casement assembly 2 in this application is a conventional casement assembly 2 and will not be described in detail in this application. The suspension assembly 3 in this application includes a supporting plate 31, and a locking hole 32 is provided in the middle of the supporting plate 31. The supporting plate 31 includes an upper plate 311 and a lower plate 312. There is a height difference between the upper plate 311 and the lower plate 312, and the upper plate 311 and the lower plate 312 are connected by a ramp plate. The locking hole 32 is provided on the ramp plate and extends toward the upper plate 311. When the trigger portion 11 is in the first position, the trigger portion 11 is inserted into the locking hole 32 and is placed at one end of the locking hole 32 on the upper plate 311. When the trigger portion 11 is in the second position, the trigger portion 11 moves toward the lower plate 312 and comes out of the locking hole 32 to hang above the locking hole 32. When the trigger portion 11 is in the first position, the trigger portion 11 is inserted into the locking hole 32. The casement assembly 2 is rotatably connected to one end of a support plate 31, the other end of which is provided with a sliding block 34. The hovering portion 12 is provided on the support plate 31, and a sliding groove 33 is provided on the end surface of the hovering portion 12 opposite the sliding block 34. When the hovering portion 12 rotates, it drives the sliding block 34 to slide within the sliding groove 33. The triggering portion 11 includes a pull-out rod 111 and a locking block 112. The pull-out rod 111 is provided on the hovering portion 12 and moves along the length of the hovering portion 12. The locking block 112 is provided at the end of the pull-out rod 111 near the upper plate 311. When the pull-out rod 111 moves toward the upper plate 311, the locking block 112 is inserted into the locking hole 32. The hovering portion 12 includes a base 121 and a locking pin 122. The base 121 is mounted on the lower plate 312 and has a retaining groove. The triggering portion 11 is inserted into the retaining groove and slides along its length. A mounting cavity 123 is formed between the triggering portion 11 and the retaining groove to accommodate the locking pin 122. The sliding groove 33 is formed at the bottom of the base 121 and communicates with the mounting cavity 123. A sliding block 34 is inserted into the sliding groove 33 and positioned within the mounting cavity 123. The locking pin 122 is positioned within the mounting cavity 123 and is rotatably connected to the sliding block 34. When the sliding block 34 slides, the locking pin 122 slides within the mounting cavity 123. One end of the rotating link 4 is rotatably connected to the base 121, and the other end of the rotating link 4 is rotatably connected to the lower plate 312. A guide is provided within the mounting cavity 123, along which the locking pin 122 slides when it slides within the mounting cavity 123.

[0034] The guide piece comprises a pair of first limiting blocks 1241 arranged at the bottom of the mounting cavity 123, and a first sliding channel 1244 is formed between the pair of first limiting blocks 1241 for sliding of the locking needle 122. The end of the first sliding channel 1244 is provided with a first guide block 1242, the first guide block 1242 is provided with a first guide surface and a second guide surface on the side thereof facing the first sliding channel 1244, the end of the mounting cavity 123 away from the first sliding channel 1244 is provided with a second guide block 1243, a first containing cavity is formed between the first guide block 1242 and the side of the second guide block 1243, and a second containing cavity is formed on the other side of the first guide block 1242 and the second guide block 1243. The first guide surface and the side wall of the mounting cavity 123 form a second sliding channel 1245, the second guide surface and the mounting cavity 123 form a third sliding channel 1246, and the side of the first guide block 1242 facing the second guide block 1243 is provided with a groove 1249 for containing the locking needle 122. The end surface of the locking needle 122 is provided with a spring 125 abutting against the trigger part 11. The locking needle 122 comprises a main body and a sliding contact, the sliding contact is fixed at one end of the main body, and the other end of the main body is rotationally connected with the sliding block 34. The side of the second guide block 1243 and the mounting cavity 123 form a fourth sliding channel 1247, the other side of the second guide block 1243 and the mounting cavity 123 form a fifth sliding channel 1248, and the depth of the fourth sliding channel 1247 is greater than that of the fifth sliding channel 1248. When the hovering part 12 and the supporting plate 31 are changed from the superimposed state to the separated state, the locking needle 122 is sequentially placed in the groove 1249 through the first sliding channel 1244, the second sliding channel 1245 and the fourth sliding channel 1247 when sliding, and when the hovering part 12 and the supporting plate 31 are changed from the separated state to the superimposed state, the locking needle 122 is reset by returning to the first sliding channel 1244 through the fifth sliding channel 1248 and the third sliding channel 1246.

[0035] With reference to Figure 1 , Figure 2 and Figure 3 , in actual use, when the window needs to be flatly opened, the pull rod 111 only needs to be unlocked, at this time, the pull rod 111 moves, but the locking block 112 is still located in the locking hole 32 on the upper plate 311, so that the guide plate and the base 121 are fixed, and when the flat opening state of the opening sash needs to be realized, the locking between the opening sash and the window frame is only needed to be unlocked, and the opening sash can be conveniently pushed out.

[0036] With reference to Figure 2 , Figure 3 , Figure 4 and Figure 8When the sash is switched from a casement-open state to a suspended state, the sash must first be closed. By turning the handle on the sash, the pull rod 111 is further driven, eventually resting on the lower plate 312 and hovering above the locking hole 32. At this point, the locking block 112 loses its locking function, and the base 121 can now rotate, allowing the sash to hover. The sash is pushed outward, and as the sash is pushed, the base 121 and the support plate 31 rotate around the rotating connecting rod 4. During rotation, the locking pin 122 slides sequentially through the first slide 1244, the second slide 1245, and the fourth slide 1247, reaching the maximum travel of the sliding groove 33, pushing the sash outward to its maximum travel. Under the sash's own weight, the sash has a tendency to return to the closed state, thereby driving the locking pin 122 to move and rest within the groove 1249, thereby locking the sash. At this point, the sash is in a suspended, open, and suspended state.

[0037] Reference Figure 3 、 Figure 4 、 Figure 5 、 Figure 8 and Figure 9 When the opening sash is turned from the suspended state to the closed state, the opening sash is pushed outward again to reach the maximum stroke of the sliding groove 33, and the locking pin 122 returns to the first slide 1244 through the groove 1249, the fifth slide 1248, and the third slide 1246. The process of the opening sash being suspended and opened to closed and reset is thus completed.

[0038] Compared with the prior art, the present invention adopts a set of hinge structures of the opening leaf to realize the horizontal opening and hanging opening of the opening leaf, which is more convenient to use.

[0039] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
