Description

Technical Field

[0001] This utility model relates to the field of window opener technology, specifically a hand-cranked window opener. Background Technology

[0002] A window opener is a device used to automatically or manually open and close windows, widely used in residential, commercial buildings, and industrial facilities. It helps users more easily operate hard-to-reach windows or automate window control, improving ventilation efficiency and safety. Window openers are mainly classified into electric and manual types based on their drive mechanism.

[0003] For example, Chinese patent CN210239456U discloses a high-efficiency hand-cranked window opener, including an outer frame and an inner frame. An installation box is installed at the bottom of the outer frame, and a screw is threaded through the installation box. A push plate is sleeved on the screw, and a chain is attached to one end of the push plate. The other end of the chain is connected to the inner frame. One end of the screw in the outermost installation box is rotatably connected to a main control rod via gears, and the other end of the screw in the installation box is connected to a control box. Adjacent installation boxes are connected via control boxes, and each control box contains a control device. A slave control rod is connected to the bottom of the control device. This invention provides a separate slave handle for each window, allowing for convenient control of the opening and closing of each window. By connecting adjacent screws through the control device, a large number of windows can be closed quickly, resulting in high efficiency.

[0004] In actual use, some of the chain plates are exposed to the outside for a long time, making them prone to rust. This causes resistance to the release and retraction of the chain plates, affecting the operation of the hand-cranked window opener. At the same time, the chain's supporting force is relatively small and is generally only suitable for small and medium-sized windows. It is difficult to drive large or heavy windows, thus reducing the practicality of the hand-cranked window opener. Utility Model Content

[0005] The purpose of this invention is to provide a hand-cranked window opener to solve the problems mentioned in the background section.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] A hand-cranked window opener includes a window body and an opening assembly. The opening assembly is disposed outside the window body. The window body includes a window frame, the outer wall of which has an outer frame. A glass panel is installed inside the outer frame. The window frame and the outer frame are hinged together. The opening assembly includes a pair of mounting seats, each located on the side of the window frame opposite to the outer frame. A square tube is disposed between the pair of mounting seats. A pair of mounting plates are fitted onto the outer side of the square tube near both ends. A first corner box is rotatably connected between the pair of mounting plates. An outer tube is installed at the bottom of the first corner box. Sliding grooves are formed on both sides of the inner wall of the outer tube. A telescopic rod is slidably connected between the pair of sliding grooves. A screw is threaded into the telescopic rod. One end of the screw is rotatably connected to the inner top surface of the outer tube. The end of the telescopic rod away from the first corner box passes through the outer tube and is fitted with a connector. The connector is connected to the glass panel.

[0008] Furthermore, the threads on the pair of screws are opposite, and the pair of screws extend through the first corner box into the interior at the end away from the connector and are fitted with a first bevel gear. The inner sidewall of the first corner box is rotatably connected to a rotating shaft, and a second bevel gear is fitted on the outside of one end of the rotating shaft. The second bevel gear meshes with the first bevel gear.

[0009] The beneficial effect of adopting the above-mentioned further solution is that, since the threads on the pair of screws are opposite and the orientations of the two second bevel gears are opposite, when the two second bevel gears rotate synchronously in the same direction, the second bevel gear meshes with the first bevel gear, causing the pair of screws to rotate synchronously in the same direction and at the same speed. The telescopic rods on both sides will move in the same direction, thereby driving the connecting parts to move synchronously, so that the glass plate is evenly stressed on both sides, avoiding the window body from jamming due to uneven stress on both sides, and ensuring the smooth opening and closing of the window body.

[0010] Furthermore, each of the two mounting bases has a square groove inside its opposite end. The two ends of the square tube are located inside the two square grooves respectively. A second corner box is installed at the bottom end of the square tube. A transmission rod is rotatably connected inside the second corner box. Both ends of the transmission rod extend through the second corner box to the outside. The two ends of the transmission rod are connected to one end of a pair of rotating shafts via couplings. A third bevel gear is sleeved on the outside of the transmission rod. A rocker arm is rotatably connected to the bottom end of the second corner box. One end of the rocker arm extends through the second corner box to the inside and is sleeved with a fourth bevel gear. The fourth bevel gear meshes with the first bevel gear.

[0011] The beneficial effect of adopting the above-mentioned further solution is that, by opening square slots inside a pair of mounting seats, after one mounting seat is installed on the left side of the window frame, one end of the square tube is inserted into the interior of the left mounting seat, and then the other mounting seat is inserted into the end of the square tube away from the left mounting seat. Then the other mounting seat is installed, so that the other mounting seat is installed on the right side of the window frame. By setting a rocker arm, when the user turns the rocker arm, it is easy to realize the rotation of the fourth bevel gear in the second corner box. Since the fourth bevel gear meshes with the third bevel gear, the transmission rod is rotated. Since the two ends of the transmission rod are connected to the two rotating shafts respectively through couplings, the two rotating shafts are rotated synchronously, in the same direction and at the same speed. The whole process only requires one-handed operation of the rocker arm, which reduces the difficulty of operation and manpower consumption, and makes the window opening operation more convenient.

[0012] Furthermore, the connector includes a connecting seat, and a support rod is rotatably connected inside the connecting seat. The upper end of the support rod is fixedly connected to the end of the telescopic rod away from the first corner box.

[0013] The beneficial effect of adopting the above-mentioned further solution is that, since the internal rotating connection of the connecting seat is a support rod, and the upper end of the support rod is fixed to one end of the telescopic rod, during the opening and closing of the window, the window frame and the outer frame will rotate at a certain angle through the hinge. Since the support rod is rotatably connected to the connecting seat, when the telescopic rod extends out from the inside of the outer tube, the telescopic rod can freely adjust its direction according to the rotation angle of the window when pushing the connecting piece, ensuring that the telescopic rod is always in a reasonable stress state, avoiding motion interference caused by rigid connection, and making the window opening and closing process smooth.

[0014] Furthermore, the connecting seat has sliding holes inside near the upper and lower ends, and a sliding rod is slidably connected inside each pair of sliding holes. A suction cup is connected to one end of each pair of sliding rods, and the suction cup is adsorbed and connected to the glass plate.

[0015] The beneficial effect of adopting the above-mentioned further solution is that by setting a sliding hole, the sliding rod can only move linearly inside the sliding hole and cannot rotate. By setting a suction cup, when the sliding rod is continuously pushed towards the glass plate, the suction cup continuously adheres to the glass plate and is attached to the glass plate, thereby realizing the rapid installation of the connector and the glass plate.

[0016] Furthermore, a circular baffle is installed at the end of the pair of slide rods away from the suction cup, and several external threads are provided on the outside of the pair of slide rods. A locking ring is threadedly connected to the outside of the pair of slide rods near the circular baffle, and the side of the locking ring away from the circular baffle abuts against the side of the connecting seat.

[0017] The beneficial effect of adopting the above-mentioned further solution is that by setting a circular baffle, the locking ring cannot be accidentally dislodged from both ends of the slide rod, thus preventing the locking ring from being lost. Since the locking ring and the slide rod are connected by threads, it is easy to rotate the locking knob to lock the position of the slide rod after it has slid, thereby increasing the negative pressure inside the suction cup and making it more firmly attached to the glass surface.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: This hand-cranked window opener includes two pairs of mounting plates, each pair of mounting plates having a first corner box rotatably connected inside. There are two screws. When the two screws rotate synchronously in the same direction and at the same speed, a rocker arm is provided. When the user turns the rocker arm, it facilitates the rotation of the fourth bevel gear inside the second corner box. Since the fourth bevel gear meshes with the third bevel gear, the transmission rod rotates. Because the two ends of the transmission rod are connected to two rotating shafts via couplings, the two rotating shafts rotate synchronously in the same direction and at the same speed, causing the two second bevel gears to rotate synchronously in the same direction. The threads on the pair of screws are opposite, and the two second bevel gears face opposite directions. When the second bevel gear meshes with the first bevel gear, the pair of screws rotate synchronously in the same direction. The two screws rotate in the same direction and at the same speed. The telescopic rods connected to the external threads of the screws move synchronously to the outside or inside of the outer tube under the sliding connection with the slide groove. This drives the connecting parts to move synchronously, so that the glass plate is evenly stressed on both sides. This avoids the window body from jamming due to uneven stress on both sides and ensures the smooth opening and closing of the window body. Since the internal rotating connection of the connecting seat is to the support rod, and the upper end of the support rod is fixed to one end of the telescopic rod, the window frame and the outer frame will rotate at a certain angle during the opening and closing of the window through the hinge. Since the support rod is rotatably connected to the connecting seat, when the telescopic rod extends out from the inside of the outer tube, the telescopic rod pushes the connecting parts to open the window body. At the same time, through the screw drive, a large pushing and pulling force is provided, which can easily drive large and heavy windows. Attached Figure Description

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.

[0026] Please see Figures 1-5 This utility model provides a technical solution: a hand-cranked window opener, including a window body 1 and an opening component 2. The opening component 2 is disposed outside the window body 1. The window body 1 includes a window frame 11, and an outer frame 12 is provided on the outer wall of the window frame 11. A glass plate 13 is installed inside the outer frame 12. The window frame 11 and the outer frame 12 are hinged together by a hinge. The opening component 2 includes a pair of mounting seats 21, both of which are disposed on the side of the window frame 11 opposite to the outer frame 12. A square tube 22 is provided between the pair of mounting seats 21, and a pair of mounting plates 23 are fitted on the outer side of the square tube 22 near both ends. A first corner box 24 is rotatably connected between a pair of mounting plates 23. An outer tube 25 is installed at the bottom of the first corner box 24. Slide grooves are provided on both sides of the inner wall of the outer tube 25. A telescopic rod 26 is slidably connected between a pair of slide grooves. A screw 27 is threaded inside the telescopic rod 26. One end of the screw 27 is rotatably connected to the inner top surface of the outer tube 25. The end of the telescopic rod 26 away from the first corner box 24 passes through the outer tube 25 and is equipped with a connector 3. The connector 3 is connected to the glass plate 13. Through the transmission of the screw 27, a large pushing and pulling force is provided, which can easily drive large and heavy windows.

[0027] 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.

[0028] Please see Figures 1-5 This utility model provides a technical solution: the threads on a pair of screws 27 are opposite, and the ends of the pair of screws 27 away from the connector 3 both extend through the first corner box 24 and are fitted with a first bevel gear 28. The inner wall of the first corner box 24 is rotatably connected to a rotating shaft, and a second bevel gear 211 is fitted on the outside of one end of the rotating shaft. The second bevel gear 211 meshes with the first bevel gear 28. The opposite ends of a pair of mounting seats 21 are each provided with a square groove, and the two ends of the square tube 22 are respectively located inside the two square grooves. A second corner box 29 is installed at the bottom end of the square tube 22. A transmission rod 210 is rotatably connected inside the second corner box 29. Both ends of the transmission rod 210 extend through the second corner box 29 to the outside, and both ends of the transmission rod 210 are connected to one end of a pair of rotating shafts via couplings. A third bevel gear 212 is sleeved on the outside of the transmission rod 210. A rocker arm 213 is rotatably connected to the bottom end of the second corner box 29. One end of the rocker arm 213 extends through the second corner box 29 to the inside and is sleeved with a fourth bevel gear 214. The fourth bevel gear 214 meshes with the first bevel gear 28. A rocker arm 213 is provided; when the user rotates the rocker arm 213 forward, the fourth bevel gear 214 inside the second corner box 29 rotates. Since the fourth bevel gear 214 meshes with the third bevel gear 212, the transmission rod 210 rotates. Because the two ends of the transmission rod 210 are connected to two rotating shafts via couplings, the two rotating shafts rotate synchronously in the same direction and at the same speed, causing the two second bevel gears 211 to rotate synchronously in the same direction. The threads on the pair of screws 27 are opposite, and the two second bevel gears 211 face opposite directions. The second bevel gear 211 meshes with the first bevel gear 28, causing the pair of screws 27 to rotate synchronously in the same direction and at the same speed. The telescopic rod 26 connected to the external threads of the pair of screws 27 will move synchronously to the outside of the outer tube 25 under the sliding connection with the slide groove, thereby driving the connector 3 to move synchronously, so that the glass plate 13 is evenly stressed on both sides, avoiding the window body 1 from being stuck when opening due to uneven stress on both sides, and ensuring the smooth opening of the window body 1.

[0029] 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.

[0030] Please see Figures 1-5 This utility model provides a technical solution: the connector 3 includes a connector 31, with a support rod 32 rotatably connected inside the connector 31. The upper end of the support rod 32 is fixedly connected to the end of the telescopic rod 26 away from the first corner box 24. The connector 31 has sliding holes 33 near both the upper and lower ends. A pair of sliding rods 34 are slidably connected inside each pair of sliding holes 33. A suction cup 35 is connected to one end of each pair of sliding rods 34, and the suction cup 35 is adsorbed and connected to the glass plate 13. A circular baffle is installed at the end of each pair of sliding rods 34 away from the suction cup 35. Several external threads are provided on the outside of each pair of sliding rods 34, and a locking ring 36 is threadedly connected to the outside of each pair of sliding rods 34 near the circular baffle. The side of the locking ring 36 away from the circular baffle abuts against the side of the connector 31. During the opening and closing of the window, the window frame 11 and the outer frame 12 are hinged together by a hinge, creating a certain angle. The extension rod 26 rotates out from the outer tube 25 because the support rod 32 is rotatably connected to the connecting seat 31. This allows the extension rod 26 to freely adjust its direction according to the rotation angle of the window when pushing the connector 3, ensuring that the extension rod 26 is always under reasonable force. By setting the sliding hole 33, the sliding rod 34 can only move linearly inside the sliding hole 33 and cannot rotate. By setting the suction cup 35, when the sliding rod 34 is continuously pushed towards the glass plate 13, the suction cup 35 continuously adheres to the glass plate 13 and is attached to the glass plate 13. Since the locking ring 36 is threadedly connected to the sliding rod 34, it is easy to rotate the locking knob to lock the position of the sliding rod 34 after sliding, thereby increasing the negative pressure inside the suction cup 35 and making it more firmly attached to the glass surface, thus realizing the rapid installation of the connector 3 and the glass plate 13.

[0031] Specifically, the working principle of this hand-cranked window opener is as follows: During use, square slots are created inside a pair of mounting bases 21. After installing one mounting base 21 on the left side of the window frame 11, one end of a square tube 22 is inserted into the left mounting base 21. Then, the other mounting base 21 is connected to the end of the square tube 22 furthest from the left mounting base 21. The other mounting base 21 is then installed on the right side of the window frame 11. A sliding hole 33 ensures that the sliding rod 34 can only move linearly within the hole and cannot rotate. A suction cup 35 allows the sliding rod 34 to continuously adhere to the glass plate 13 as it is pushed towards the glass plate 13. The suction cup 35 adheres to the glass plate 13. Since the locking ring 36 is threadedly connected to the sliding rod 34, the locking knob can be rotated to lock the sliding rod 34 in place, increasing the negative pressure inside the suction cup 35 and making it more firmly attached to the glass surface. This achieves the connection of the connecting piece 3. The quick installation of the glass plate 13 allows the user to rotate the rocker arm 213 in the forward direction, facilitating the rotation of the fourth bevel gear 214 inside the second corner box 29. Since the fourth bevel gear 214 meshes with the third bevel gear 212, the transmission rod 210 rotates. Since the two ends of the transmission rod 210 are connected to the two rotating shafts through couplings, the two rotating shafts rotate synchronously in the same direction and at the same speed, causing the two second bevel gears 211 to rotate synchronously in the same direction. The threads on the pair of screws 27 are opposite, and the two second bevel gears 211 face opposite directions. The second bevel gear 211 meshes with the first bevel gear 28, causing the pair of screws 27 to rotate synchronously in the same direction and at the same speed. The telescopic rod 26 connected to the external threads of the pair of screws 27 will move synchronously to the outside of the outer tube 25 under the sliding connection with the slide groove, thereby driving the connecting piece 3 to move synchronously, so that the glass plate 13 is evenly stressed on both sides, avoiding the window body 1 from being stuck due to uneven stress on both sides, and ensuring the smooth opening of the window body 1.

[0032] It should be noted that all standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. Furthermore, since this application is mainly used to protect mechanical devices, the control methods and circuit connections will not be explained in detail in this application.
