Description

Technical Field

[0001] This utility model belongs to the field of door and window technology, and specifically relates to a door and window. Background Technology

[0002] Handles are devices installed on door and window sashes, serving both an opening and closing locking function. When the door or window is closed, the handle, along with other accessories, securely locks the opening door or window sash to the fixed frame, thus fixing the relative positions of the inner and outer frames. Handles are commonly made of materials such as aluminum alloy, copper, stainless steel, plexiglass, and plastic. They come in various forms and sizes. Besides meeting the requirements of comfortable handling and reasonable force distribution, they also have a decorative effect; therefore, the materials and shapes are selected from pre-made products or custom-designed according to the architectural design requirements.

[0003] Existing door and window mechanisms involve rotating handles, which move the bolt through a locking bar to lock and open the door. However, this method is too simple to open and close, lacks a limit to the number of positions, and is prone to accidental opening by children, resulting in safety accidents. Therefore, we propose a new type of door and window mechanism. Utility Model Content

[0004] In order to overcome the above-mentioned technical problems, the purpose of this utility model is to provide a door and window that solves the problem mentioned in the background art that the existing door and window rotating handles, which drive the lock tongue to move through the lock rod to realize the locking and opening of the door, are too simple to open and close, have no limit structure, and are easy to cause children to accidentally open them and cause safety accidents, resulting in poor safety.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A door and window, including a window frame, a latch assembly inside the window frame, a mating groove on the surface of the latch assembly, a sealing gasket fixedly connected to the surface of the window frame, a handle structure installed on the surface of the window frame, the handle structure including a fixing plate, a handle rotatably connected to the surface of the fixing plate, a fixing block fixedly connected to the surface of the handle, a limit block fixedly connected to the surface of the fixing block, a baffle one fixedly connected to the inner wall of the fixing plate, a baffle two fixedly connected to the bottom of the limit block, a coil spring sleeved on the outer side of the fixing block, a locking structure inside the handle, the locking structure including a sliding groove, a limit plate slidably connected inside the sliding groove, a pressing plate fixedly connected to one end of the limit plate, a locking rod fixedly connected to the other end of the limit plate, and a spring sleeved on the outer side of the locking rod.

[0006] Preferably, the sealing gasket is made of rubber.

[0007] Preferably, the surface of the fixing plate has a circular groove with the same radius as the fixing block, the fixing block is rotatably connected in the circular groove, and the radius of the limiting block is larger than the radius of the fixing block.

[0008] Preferably, the first baffle is disposed below the first circular groove, and the two ends of the coil spring are fixedly connected to the second baffle and the coil spring respectively, and the side surface of the coil spring is in contact with the surface of the fixing plate and the limiting block respectively.

[0009] Preferably, the groove is formed inside the handle, and the cross-sectional area of ​​the limiting plate is larger than the cross-sectional area of ​​the pressing plate.

[0010] Preferably, the surfaces of the fixing block and the limiting block are each provided with a square groove that matches the locking rod. The locking rod passes through the inner wall of one side of the sliding groove and is slidably connected in the square groove. The surfaces of the mating groove and the locking rod are both provided with rounded corners. The locking rod is slidably connected in the mating groove. The cross-sections of the locking rod and the mating groove are both square.

[0011] Preferably, the two ends of the spring are fixedly connected to the surface of the limiting plate and the inner wall of the slide groove, respectively, and the spring does not contact the locking rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This type of door and window features a handle structure and a locking structure. When in use, pressing the press plate causes the limiting plate to slide within the groove, moving the locking rod into the mating groove. At this point, the spring is compressed, and the locking rod, after being inserted into the mating groove, engages with it. Turning the handle then drives the locking tongue assembly via the locking rod, thereby locking and opening the door and window. Simultaneously, when the handle rotates on the fixed plate, it causes the limiting block to rotate as well. The baffle at the bottom of the limiting block causes the coil spring to deform, giving the handle a tendency to return to its original shape. This allows the handle to automatically reset when no force is applied. The coil spring increases the resistance when the handle rotates, reducing the possibility of accidental rotation. Only after pressing the press plate to insert the locking rod into the mating groove and then rotating the handle can the door and window be opened and closed. Simply rotating the handle is insufficient to open or close the door and window, thus enhancing security.

[0013] 2. This type of door and window is equipped with a sealing gasket, which increases the tightness of the window frame when closed, making the window frame more airtight after closing, effectively preventing rainwater and noise from entering. At the same time, it increases the friction between the window frame and the outer frame, making the window frame more resistant to opening and closing, further increasing safety.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-5 One embodiment provided by this utility model: A door or window includes a window frame 1. A latch assembly 11 is disposed inside the window frame 1. A mating groove 12 is formed on the surface of the latch assembly 11. A sealing gasket 2 is fixedly connected to the surface of the window frame 1. A handle structure 3 is installed on the surface of the window frame 1. The handle structure 3 includes a fixing plate 31. A handle 32 is rotatably connected to the surface of the fixing plate 31. A fixing block 33 is fixedly connected to the surface of the handle 32. A limit block 34 is fixedly connected to the surface of the fixing block 33. A baffle 35 is fixedly connected to the inner wall of the fixing plate 31. The bottom of the limit block 34 is fixedly connected to... A second baffle 36 is connected to the handle 32. A coil spring 37 is sleeved on the outside of the fixing block 33. The handle 32 has an engagement structure 4 inside. The engagement structure 4 includes a slide groove 41. A limit plate 43 is slidably connected inside the slide groove 41. A pressing plate 42 is fixedly connected to one end of the limit plate 43. A locking rod 44 is fixedly connected to the other end of the limit plate 43. A spring 45 is sleeved on the outside of the locking rod 44. The handle structure 3 and the engagement structure 4 are provided. When in use, pressing the pressing plate 42 causes the limit plate 43 to slide in the slide groove 41, which in turn causes the locking rod 44 to move into the mating groove. When the handle 32 moves within the groove 12, the spring 45 is compressed, and the locking rod 44 engages with the groove 12 after being inserted into it. Rotating the handle 32 at this time drives the locking tongue assembly 11 via the locking rod 44, thereby locking and opening the door / window. Simultaneously, as the handle 32 rotates on the fixed plate 31, it causes the limiting block 34 to rotate as well. The baffle 36 at the bottom of the limiting block 34 causes the coil spring 37 to deform, thus giving the handle 32 a tendency to return to its original shape. This allows the handle 32 to automatically reset when no force is applied. The coil spring 37 enhances the handle's stability. The resistance during rotation of handle 32 reduces the possibility of accidental rotation. After pressing the pressing plate 42 to insert the locking rod 44 into the mating groove 12, the handle 32 can be rotated to open and close the door and window. Simply rotating the handle 32 cannot open or close the door and window, thus increasing safety. A sealing gasket 2 is provided to increase the tightness of the window frame 1 when closed, resulting in better sealing after the window frame 1 is closed, effectively preventing rainwater and noise from entering. At the same time, it increases the friction between the window frame 1 and the outer frame, making the resistance when opening and closing the window frame 1 greater, further increasing safety.

[0018] Furthermore, the sealing gasket 2 is made of rubber, which increases the tightness of the window frame 1 when closed, making the window frame 1 more airtight after closing, increasing the friction between the window frame 1 and the outer frame, making the window frame 1 more resistant to opening and closing, and further increasing safety.

[0019] Furthermore, the surface of the fixing plate 31 is provided with a circular groove of the same radius as the fixing block 33. The fixing block 33 is rotatably connected in the circular groove. The radius of the limiting block 34 is larger than the radius of the fixing block 33. When the handle 32 is rotated, the fixing block 33 and the limiting block 34 on the other side of the fixing plate 31 can be rotated together. The limiting block 34 limits the handle 32 to prevent the handle 32 and the fixing block 33 from sliding out of the circular groove.

[0020] Furthermore, baffle 35 is positioned below the circular groove 1. The two ends of coil spring 37 are fixedly connected to baffle 36 and coil spring 37 respectively. The side surface of coil spring 37 contacts the surface of fixed plate 31 and limiting block 34 respectively to prevent handle 32 from shaking. When handle 32 rotates on fixed plate 31, it drives limiting block 34 to rotate together. Baffle 36 at the bottom of limiting block 34 will deform coil spring 37, thereby making handle 32 tend to return to its original shape.

[0021] Furthermore, the slide groove 41 is formed inside the handle 32, and the cross-sectional area of ​​the limiting plate 43 is larger than the cross-sectional area of ​​the pressing plate 42. The limiting plate 43 limits the pressing plate 42 to prevent it from sliding out of the slide groove 41.

[0022] Furthermore, both the fixing block 33 and the limiting block 34 have square grooves on their surfaces that match the locking rod 44. The locking rod 44 slides through the inner wall of one side of the sliding groove 41 and is slidably connected in the square groove. The surfaces of the mating groove 12 and the locking rod 44 are rounded to facilitate the mutual insertion of the mating groove 12 and the locking rod 44. The locking rod 44 is slidably connected in the mating groove 12. The cross-sections of the locking rod 44 and the mating groove 12 are both square. Pressing down the pressing plate 42 causes the limiting plate 43 to slide in the sliding groove 41, causing the locking rod 44 to move into the mating groove 12. After the locking rod 44 is inserted into the mating groove 12, it engages with the mating groove 12. At this time, turning the handle 32 can drive the locking tongue assembly 11 through the locking rod 44, thereby locking and opening the door and window.

[0023] Furthermore, the two ends of the spring 45 are fixedly connected to the surface of the limiting plate 43 and the inner wall of the slide groove 41, respectively. The spring 45 does not contact the locking rod 44. When no force is applied, the spring 45 pushes the limiting plate 43, causing the limiting plate 43 to abut against the inner wall of the slide groove 41 at the end away from the fixing block 33. At this time, the surface of the pressing plate 42 and the handle 32 are on the same plane.

[0024] Working principle: When in use, pressing the press plate 42 causes the limiting plate 43 to slide in the slide groove 41, which in turn causes the locking rod 44 to move into the mating groove 12. At this time, the spring 45 is compressed, and the locking rod 44 is inserted into the mating groove 12 and engages with it. At this time, turning the handle 32 can drive the locking tongue assembly 11 through the locking rod 44, thereby locking and opening the door and window. At the same time, when the handle 32 rotates on the fixed plate 31, it drives the limiting block 34 to rotate together. The baffle 36 at the bottom of the limiting block 34 will cause the coil spring 37 to deform, which will make the handle 32 tend to return to its original shape. When the handle 32 is not under force, it can reset itself. Turning the handle 32 alone cannot open or close the door and window. The press plate 42 must be pressed to insert the locking rod 44 into the mating groove 12 before the handle 32 can be turned to open or close the door and window. The sealing gasket 2 makes the sealing of the window frame 1 better after it is closed, increases the friction between the window frame 1 and the outer frame, and makes the resistance of the window frame 1 greater when it is opened and closed.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
