Description

Technical Field

[0001] This utility model relates to the field of door and window technology, and in particular to a device for preventing misoperation. Background Technology

[0002] Inward-opening and tilt-and-turn windows are a type of multifunctional window that combines two opening methods: inward opening (opening inward) and inward tilting (tilting inward). The state can be switched through hardware transmission, and they are widely used in residential buildings, office buildings and other buildings.

[0003] Inward-opening and tilt-and-turn windows typically feature anti-operation devices to limit the movement of the limiting components, ensuring proper installation and use of the window sash. However, existing anti-operation devices can be misoperated due to bumps during transportation causing the window sash to bounce, leading to the release of the limiting components. This causes structural parts on the transmission assembly to enter the wrong position, preventing the transmission assembly from transitioning from the locked state to the inward-opening and tilt-and-turn state. Consequently, the window sashes become jammed and cannot be opened, affecting normal installation and use. Utility Model Content

[0022] See Figures 1 to 5 , Figure 1 An exploded view of the safety component 20 of the anti-misoperation device provided in an embodiment of the present invention; Figure 2 A front view of the base 21 provided in an embodiment of the present utility model; Figure 3 A rear structural view of the base 21 provided in an embodiment of the present utility model; Figure 4 A top view of the state limiting member 22 provided in an embodiment of the present utility model; Figure 5 This is an overall structural diagram of the lifting seat 30 provided in one embodiment of the present utility model. Figures 1 to 5 As shown, the anti-misoperation device provided by this utility model includes a transmission assembly 10, a safety assembly 20, and a lifting seat 30. The transmission assembly 10 is installed on the inward-opening and tilt-and-turn window. The safety assembly 20 is installed on the transmission assembly 10 and includes a base 21 and a state limiting member 22. The state limiting member 22 is embedded in the base 21 and has a limiting structure 23, which is used to restrict the movement of the transmission assembly 10. The lifting seat 30 is installed on the window frame of the inward-opening and tilt-and-turn window and includes a pressing member 31, which is used to press the state limiting member 22 to switch the transmission assembly 10 between a locked state and an inward-opening and tilt-and-turn state.

[0023] Specifically, the anti-misoperation device may include a transmission assembly 10, a safety assembly 20, and a lifting seat 30. The transmission assembly 10 is installed on the inward-opening and tilt-and-turn window and is used to connect the window sash and hardware to switch the state of the inward-opening and tilt-and-turn window. For example, if the transmission assembly 10 is connected to the handle and the window sash, the user can trigger the movement of the transmission assembly 10 by rotating the handle to switch the state of the inward-opening and tilt-and-turn window. The state of the inward-opening and tilt-and-turn window may include a locked state and an inward-opening and tilt-and-turn state. The inward-opening and tilt-and-turn state is divided into an inward-opening state and an inward-tilting state, and can be switched between the locked state and the inward-opening state and between the locked state and the inward-tilting state by the transmission assembly 10.

[0024] The safety component 20 is installed on the transmission component 10 as a safety device, restricting the movement of the transmission component 10 and preventing it from directly switching between the inward-opening and inward-folding states. The safety component 20 may include a base 21 and a state limiting member 22. The state limiting member 22 is embedded in the base 21 and has a limiting structure 23. This limiting structure 23 cooperates with structural components on the transmission component 10 to restrict the movement of the transmission component 10. The state limiting member 22 may be a locking tongue, primarily used for mechanically limiting the transmission component 10 to prevent accidental operation.

[0025] The lifting seat 30 is installed on the window frame of the inward-opening and tilt-and-turn window. It is equipped with a pressing member 31, which is used to press the state limiting member 22 to change the position of the state limiting member 22, thereby allowing the transmission assembly 10 to switch between the locked state and the inward-opening and tilt-and-turn state. The pressing member 31 can be a stop block, which is riveted to the lifting seat 30 and is used to press the state limiting member 22 when it comes into contact with it.

[0026] For example, when the inward-opening and tilt-and-turn window is in the locked state, the pressing member 31 presses the state limiting member 22 to restrict the state limiting member 22 to a first position. At this time, the structural members on the transmission assembly 10 can move freely, and the user can switch the state of the inward-opening and tilt-and-turn window from the locked state to the inward-opening state or the tilt-and-turning state through the transmission assembly 10. When the inward-opening and tilt-and-turn window is in the inward-opening state or the tilt-and-turning state, the pressing member 31 releases the state limiting member 22. According to the state of the inward-opening and tilt-and-turning window, the limiting structure 23 restricts the structural members of the transmission assembly 10 to a fixed position to prevent the structural members from moving, thereby preventing direct switching from the inward-opening state to the tilt-and-turning state, or from the tilt-and-turning state to the inward-opening state.

[0027] See Figures 6 to 10 , Figure 6 A rear structural view of the state limiting member 22 provided in the first embodiment of this utility model; Figure 7 A structural diagram showing the pin 11 and the state limiting member 22 on the transmission assembly 10 provided in the first embodiment of this utility model in a locked state; Figure 8A structural diagram showing the pin 11 and the state limiting member 22 on the transmission assembly 10 provided in the first embodiment of this utility model in the inwardly open state; Figure 9 A structural diagram showing the pin 11 and the state limiting member 22 on the transmission assembly 10 provided in the first embodiment of this utility model in the inward tilting state; Figure 10 This diagram illustrates the relative positional relationship between the safety component 20 and the lifting seat 30 when the transmission component 10 provided in the first embodiment of this utility model is in the locked state. In this embodiment, the state limiting member 22 has a groove 24, and a protrusion 25 is provided in the groove 24. The protrusion 25 includes a first limiting groove 231 and a second limiting groove 232 arranged laterally at intervals. The limiting structure includes the first limiting groove 231, the second limiting groove 232, and a limiting rib 233.

[0028] Among them, such as Figure 6 As shown, one side of the state limiting member 22 is provided with a groove 24, and a protrusion 25 is provided in the groove 24. The protrusion 25 is formed with a first limiting groove 231, a second limiting groove 232, and a limiting rib 233. The first limiting groove 231 and the second limiting groove 232 are used to limit the position of the structural members on the transmission assembly 10. For example, when the inward-opening and tilt-and-turn window is in the inward-opening state, the structural member is limited in the first limiting groove 231. When the inward-opening and tilt-and-turn window is in the tilt-and-turning state, the structural member is limited in the second limiting groove 232. When the window sash jumps and causes the pressing member 31 to malfunction, the structural member on the transmission assembly 10 will abut against the limiting rib 233, preventing the state limiting member 22 from being released. At this time, the transmission assembly 10 can smoothly enter the inward-opening and tilt-and-turning state from the locked state, thereby ensuring that the window sash can be opened and installed normally. When the inward-opening and tilt-and-turn window is in the locked state, the pressing member 31 presses the state limiting member 22, so that the state limiting member 22 fits against the base 21, increasing the distance between the protrusion 25 and the structural member, so that the structural member can move freely along the protrusion 25 and will not be restricted in the first limiting groove 231 or the second limiting groove 232.

[0029] As a further embodiment, the transmission assembly 10 includes a pin 11 that moves along the protrusion 25; wherein, when the pin 11 is located in the first limiting groove 231 or the second limiting groove 232, the transmission assembly 10 is restricted to an inward-opening state or an inward-folding state.

[0030] Specifically, the structural component of the transmission assembly 10 can be a pin 11. After the transmission assembly 10 and the safety assembly 20 are assembled, the pin 11 is located on one side of the protrusion 25 and can move along the protrusion 25. Figure 7 As shown, Figure 7This is a structural diagram of an inward-opening and tilt-and-turn window in the locked state. At this time, the pin 11 can slide freely, allowing it to stop on one side of the first limiting groove 231 or the second limiting groove 232, facilitating switching from the locked state to the inward-opening or tilt-and-turn state. Figure 7 It can be seen that when the inward-opening and tilt-and-turn window is in the locked state, the pressing member 31 presses against the limiting member 22, thereby forming a channel for the pin shaft 11 to move. Figure 8 This is a structural diagram of an inward-opening and tilt-and-turn window in its inward-opening state. Figure 8 It can be seen that when the inward opening and tilting window is switched from the locked state to the inward opening state, the pressing member 31 releases the state limiting member 22, and the state limiting member 22 returns to the initial position. At this time, the pin 11 is located in the first limiting groove 231 and cannot be disengaged from the first limiting groove 231, thus avoiding direct switching from the inward opening state to the tilting state. Figure 9 This is a structural diagram of an inward-opening and tilt-and-turn window in the tilt-and-turn position. At this time, the pin 11 is located within the second limiting groove 232 and cannot disengage from it, preventing a direct switch from the tilt-and-turn position to the inward-opening position. Figures 7 to 9 It can be seen that the inward-opening and tilt-and-turn windows can only be switched from the locked state to the inward-opening state, or from the locked state to the tilt-and-turning state; they cannot be switched directly between the inward-opening and tilt-and-turning states. For example... Figure 10 As shown, Figure 10 Diagram showing the relative positions of the lift seat 30 and the safety component 20 when the inward-opening and tilt-and-turn window is in the locked state.

[0031] See Figures 11 to 15 , Figure 11 A front view of the state limiting member 22 provided in the second embodiment of this utility model; Figure 12 A structural diagram of the transmission assembly 10 and the state limiting member 22 in the locked state according to the second embodiment of this utility model; Figure 13 This is a structural diagram of the transmission assembly 10 in the inwardly open state provided in the second embodiment of the present invention; Figure 14 This is a structural diagram of the transmission assembly 10 in the inverted state provided in the second embodiment of the present invention; Figure 15 This diagram illustrates the relative positional relationship between the safety component 20 and the lifting seat 30 when the transmission assembly 10 is in the locked state, according to the second embodiment of this utility model. In this embodiment, the limiting structure 23 includes a limiting protrusion 234, which is disposed on the side of the state limiting member 22 facing the transmission assembly 10.

[0032] Among them, such as Figure 11 As shown, the limiting structure 23 may include a limiting protrusion 234, which is located on one side of the state limiting member 22. The limiting protrusion 234 is used to cooperate with the structural members of the transmission assembly 10 to achieve the purpose of limiting the transmission assembly 10.

[0033] As a further embodiment, the transmission assembly 10 includes a slide groove 12 for sliding the limiting protrusion 234, and the slide groove 12 is provided with a first slot 13 and a second slot 14 at intervals; wherein, when the limiting protrusion 234 is located in the first slot 13 or the second slot 14, the transmission assembly 10 is restricted to an inward-opening state or an inward-folding state.

[0034] Among them, such as Figure 12 As shown, the transmission assembly 10 may include a slide groove 12 for sliding the limiting protrusion 234. A first slot 13 and a second slot 14 are spaced apart within the slide groove 12. When the inward-opening and tilt-and-turn window is in the locked state, the pressing member 31 presses against the limiting member 22. The limiting protrusion 234 is located in the slide groove 12 and not in any slot, allowing it to move freely along the slide groove 12. At this time, the inward-opening and tilt-and-turn window can be switched from the locked state to the inward-opening state or the tilt-and-turning state. The slide groove 12 can also be used to release the limiting member 22 when the window sash jumps, causing the pressing member 31 to malfunction. In this case, the transmission assembly 10 can smoothly enter the inward-opening and tilt-and-turning state from the locked state, thereby ensuring the normal opening and installation of the window sash. Figure 13 The diagram shows the structure of the inward-opening and tilt-and-turn window in the inward-opening state. The pressing member 31 can release the state limiting member 22 to place the limiting protrusion 234 in the first slot 13. The first slot 13 limits the limiting protrusion 234 to prevent it from moving into the second slot 14, thereby preventing the inward-opening and tilt-and-turn window from switching directly from the inward-opening state to the tilt-and-turning state. Figure 14 The diagram shows the structure of the inward-opening and tilt-and-turn window in the tilt-and-turn state. The pressing member 31 can release the state limiting member 22 to place the limiting protrusion 234 in the second slot 14. The second slot 14 limits the limiting protrusion 234 to prevent it from moving into the first slot 13, thereby preventing the inward-opening and tilt-and-turn window from switching directly from the tilt-and-turn state to the inward-open state.

[0035] See Figures 1 to 5 As a further embodiment, the base 21 has a clearance groove 26, which is used to install the state limiting member 22.

[0036] One end of the base 21 may have a clearance groove 26 for installing the status limiting member 22. In use, the status limiting member 22 is placed within the clearance groove 26 to complete its installation. A limiting point 222 may be provided on the base 21 to prevent the status limiting member 22 from falling off. Additionally, the base 21 may have a mounting through hole 221 through which it can be installed onto the transmission assembly 10. A positioning protrusion 223 may also be provided on the base 21 for easy positioning during installation.

[0037] As a further embodiment, the bottom of the clearance groove 26 is provided with a fixing post 27, and an elastic element 28 is installed on the fixing post 27. The elastic element 28 is used to connect the state limiting element 22.

[0038] The bottom of the clearance groove 26 may be provided with at least one fixed post 27, and each fixed post 27 is provided with an elastic element 28, which can be connected to the state limiting element 22. For example, a fixed post 27 can be provided at both ends of the bottom of the clearance groove 26, and an elastic element 28 can be installed on each fixed post 27, which is connected to the state limiting element 22. When the inward opening and tilting window is in the locked state, the pressing member 31 presses the state limiting element 22, thereby pressing the state limiting element 22 toward the inside of the clearance groove 26, which in turn causes the state limiting element 22 to press the elastic element 28. When the inward opening and tilting window is in the inward opening state or the tilting state, the pressing member 31 releases the state limiting element 22. At this time, the state limiting element 22 moves toward the outside of the clearance groove 26 under the action of the elastic element 28, returning to its initial position.

[0039] As a further embodiment, the state limiting member 22 has a mounting groove 29 for placing the elastic member 28 relative to the fixed post 27.

[0040] A mounting groove 29 may be provided on one side of the state limiting member 22 relative to the fixing post 27. The mounting groove 29 is used to install the elastic member 28 to improve the stability during connection. The number of mounting grooves 29 is the same as the number of fixing posts 27, and they are provided relative to the fixing posts 27. For example, if the fixing posts 27 are located at both ends of the bottom of the clearance groove 26, then the mounting grooves 29 may be provided at both ends of the bottom of the state limiting member 22.

[0041] See Figure 5 As a further embodiment, the lifting seat 30 includes an adjustment component 32, which is riveted to the lifting seat 30.

[0042] The adjustment component 32 is used to provide upward support to the safety component 20 when the inward-opening and tilt-and-turn window is in the locked state, thereby increasing the overall height of the window sash, adjusting the gap between the frame and the sash, and preventing the window sash from sagging at the corner.

[0043] As a further embodiment, the adjusting assembly 32 includes a roller sleeve 321 and an eccentric shaft 322, the eccentric shaft 322 passing through the roller sleeve 321 and riveted to the lifting seat 30.

[0044] The adjusting component 32 may include a roller sleeve 321 and an eccentric shaft 322. The eccentric shaft 322 passes through the roller sleeve 321 and is riveted to the lifting seat 30. Adjusting the eccentric shaft 322 provides an upward supporting force to the safety component 20, thereby raising the overall height of the window sash and preventing the window sash from sagging at the corners. Figure 5As shown. In addition, the lifting seat 30 may also be provided with multiple punch bridges 35 for installation and positioning, and may also be provided with an adjusting shaft 33 and a nut 34. The adjusting shaft 33 passes through the lifting seat 30 and the nut 34 for riveting connection. By rotating the adjusting shaft 33, the nut 34 is driven to lock onto the window frame of the inward opening and tilting window.

[0045] This invention adjusts the state of the inward-opening and tilt-and-turn window through a limiting structure and a pressing component, so that the inward-opening and tilt-and-turn window can only switch between the locked state and the inward-opening state, and between the locked state and the tilt-and-turning state, thus avoiding direct switching between the inward-opening and tilt-and-turning states and preventing damage and malfunction of the inward-opening and tilt-and-turn window.

[0046] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
