Technical Field

[0001] This utility model relates to the field of door and window technology, specifically to an aluminum alloy door and window transmission device with multi-point locking function. Background Technology

[0002] Aluminum alloy doors and windows are a type of door and window with aluminum alloy extruded profiles as the main frame structure. They include composite forms such as aluminum-wood composite and aluminum-plastic composite. Currently, aluminum alloy doors and windows generally use a transmission mechanism to achieve opening and closing. Existing technology includes two forms: single-point locking and multi-point locking. Single-point locking has a simple structure, but its sealing and anti-theft performance is insufficient. While existing multi-point locking actuators can drive multiple locking points with a single handle, their transmission stability, the synchronicity of movement of each locking point, and the overall sealing effect still need improvement in practical applications. Some complex actuators also suffer from easy deformation and jamming.

[0003] Therefore, we propose an aluminum alloy door and window actuator with multi-point locking function to solve the above problems. Utility Model Content

[0005] (II) Technical Solution To achieve the above objectives, this utility model specifically adopts the following technical solution: An aluminum alloy door and window actuator with multi-point locking function includes an actuator assembly, which includes several interlocking mechanisms. The interlocking mechanisms are respectively arranged inside the perimeter of the movable window sash, and adjacent interlocking mechanisms are mutually driven by a linkage mechanism. The interlocking mechanism includes a main lock, secondary bolts located on both sides of the main lock, and a secondary bolt linkage rod and an auxiliary linkage rod for driving the secondary bolts.

[0006] Furthermore, the interlocking mechanism also includes a gear guide seat fixedly installed inside the movable window sash, and one end of the transmission rod of the main lock extends into the interior of the gear guide seat and is provided with a main gear.

[0007] Furthermore, the outline of the middle part of the gear guide seat is adapted to the main gear, and the two sides of the gear guide seat are provided with guide rails that are respectively movably connected to the secondary locking tongue linkage rod and the auxiliary linkage rod.

[0008] Furthermore, the opposing surfaces of the secondary locking tongue linkage rod and the auxiliary linkage rod are provided with main gear sets that mesh with both sides of the main gear, and secondary locking tongue drive blocks are provided at both ends of the secondary locking tongue linkage rod.

[0009] Furthermore, the two ends of the auxiliary linkage rod pass through the interior of the secondary lock tongue drive block at both ends of the secondary lock tongue linkage rod, and a guide inclined slide is provided on one side of the secondary lock tongue drive block.

[0010] Furthermore, one end of the movable window sash is movably installed inside the fixed window sash via a hinge. All four sides of the movable window sash are provided with latch sleeves for installing the secondary latch. One end of the secondary latch extends to one side of the secondary latch drive block and is provided with at least two rotating shafts. One end of the rotating shaft extends into the interior of the guide inclined slide.

[0011] Furthermore, the linkage mechanism includes linkage gears rotatably disposed inside the four corners of the movable window sash, with chains meshing on the linkage gears, and the two ends of the chains being connected to two adjacent secondary locking tongue drive blocks in two adjacent sets of interlocking mechanisms, respectively.

[0015] (III) Beneficial Effects Compared with the prior art, this utility model provides an aluminum alloy door and window actuator with multi-point locking function, which has the following advantages: This utility model, through the setting of a transmission system composed of interlocking and linkage mechanisms, efficiently transforms the 90-degree rotational motion of a single handle into the synchronous linkage of the main lock and auxiliary lock tongue around the movable window sash. The design of the main gear, multiple gear drives and auxiliary linkage rods significantly improves the transmission stability and avoids deformation and jamming of the auxiliary lock tongue linkage rod.

[0018] 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.

[0019] Example like Figure 1-8 As shown, an embodiment of this utility model proposes an aluminum alloy door and window transmission device with multi-point locking function, including a transmission device assembly 1. The transmission device assembly 1 includes a plurality of interlocking mechanisms 11, which are respectively arranged inside the periphery of the movable window sash 2. Adjacent interlocking mechanisms 11 are mutually driven by a linkage mechanism 12. The interlocking mechanism 11 includes a main lock 111, secondary lock tongues 112 located on both sides of the main lock 111, and secondary lock tongue linkage rods 113 and auxiliary linkage rods 114 for driving the secondary lock tongues 112.

[0020] Multiple interlocking mechanisms 11 are interconnected through linkage mechanism 12 to achieve multi-point locking. When installed on doors and windows, together with the sealing rings on the doors and windows, they greatly improve the overall sealing performance, wind pressure resistance and anti-theft security of the doors and windows.

[0021] like Figure 1-8 As shown, in some embodiments, the interlocking mechanism 11 further includes a gear guide seat 115 fixedly disposed inside the movable window sash 2, and one end of the transmission rod 1111 of the main lock 111 extends into the interior of the gear guide seat 115 and is provided with a main gear 1112.

[0022] The rotational motion of the main lock 111 is converted into gear transmission. The main gear 1112 is set at the end of the transmission rod 1111 of the main lock 111 and placed in the gear guide seat 115, which provides a power source and a stable support environment for subsequent linear motion conversion. The gear transmission has high efficiency and precise motion. The gear guide seat 115 ensures the stability of the position of the main gear 1112, preventing it from shifting or vibrating during transmission, and ensuring the reliability of power transmission.

[0023] like Figure 1-8 As shown, in some embodiments, the outline of the middle part of the gear guide seat 115 is adapted to the main gear 1112, and the two sides of the gear guide seat 115 are provided with guide rails 1151 that are movably connected to the secondary locking tongue linkage rod 113 and the auxiliary linkage rod 114, respectively.

[0024] The gear guide seat 115 is designed to serve the dual functions of a "gear chamber" and a "linear guide rail". The middle part accommodates and constrains the main gear 1112, while the guide rails 1151 on both sides provide a linear motion track for the secondary locking tongue linkage rod 113 and the auxiliary linkage rod 114, which improves the rigidity and integrity of the entire interlocking mechanism 11. The gear guide seat 115 can effectively prevent the secondary locking tongue linkage rod 113 and the auxiliary linkage rod 114 from warping or jamming during movement, ensuring smooth movement.

[0025] like Figure 1-8 As shown, in some embodiments, the opposite surfaces of the secondary locking tongue linkage rod 113 and the auxiliary linkage rod 114 are provided with main gear sets 116 that mesh with both sides of the main gear 1112, and the two ends of the secondary locking tongue linkage rod 113 are provided with secondary locking tongue drive blocks 1131.

[0026] The main gear 1112 acts as the driving component, and its two sides mesh with the main gear set 116 on the secondary lock tongue linkage rod 113 and the auxiliary linkage rod 114. When the main gear 1112 rotates, it will drive the two to make synchronous linear motion in opposite directions. The secondary lock tongue drive block 1131 is fixed on the secondary lock tongue linkage rod 113 and moves with it.

[0027] like Figure 1-8 As shown, in some embodiments, the two ends of the auxiliary linkage rod 114 pass through the interior of the auxiliary lock tongue drive block 1131 at both ends of the auxiliary lock tongue linkage rod 113, and a guide inclined slide 1132 is provided on one side of the auxiliary lock tongue drive block 1131.

[0028] The auxiliary linkage rod 114 passes through the secondary locking tongue drive block 1131, and the two form a sliding fit. The guide inclined slide 1132 opened on the secondary locking tongue drive block 1131 provides a constraint path for the movement trajectory of the secondary locking tongue 112, realizing the decoupling between the linear motion of the secondary locking tongue linkage rod 113 and the composite motion of the secondary locking tongue drive block 1131. The auxiliary linkage rod 114 is mainly responsible for transmitting force, while the secondary locking tongue drive block 1131 is responsible for converting the linear motion into a specific locking motion, such as an inclined locking motion.

[0029] like Figure 1-8 As shown, in some embodiments, one end of the movable window sash 2 is movably installed inside the fixed window sash 3 via a hinge. The movable window sash 2 is provided with a latch sleeve 21 for installing the secondary latch 112 on all four sides. One end of the secondary latch 112 extends to one side of the secondary latch drive block 1131 and is provided with at least two rotating shafts 1121. One end of the rotating shaft 1121 extends into the interior of the guide inclined slide 1132.

[0030] The secondary locking tongue 112 is slidably connected to the guide inclined slide 1132 via the rotating shaft 1121. When the secondary locking tongue drive block 1131 moves linearly, the inclined surface of its guide inclined slide 1132 will squeeze the rotating shaft 1121 of the secondary locking tongue 112, forcing the rotating shaft 1121 to move along the slide track, thereby driving the secondary locking tongue 112 to complete the compound action of "diagonally extending to lock" or "diagonally retracting to unlock". At the same time, it can generate a component force that presses the window sash against the window frame, which greatly enhances the compression of the sealing strip and thus significantly improves the sealing performance.

[0031] like Figure 1-8 As shown, in some embodiments, the linkage mechanism 12 includes linkage gears 121 rotatably disposed inside the four corners of the movable window sash 2. A chain 122 is meshed on the linkage gear 121, and the two ends of the chain 122 are respectively connected to two adjacent secondary lock tongue drive blocks 1131 in two adjacent sets of interlocking mechanisms 11.

[0032] A linkage mechanism 12 system consisting of linkage gears 121 and chains 122 is set at the four corners of the movable window sash 2. When a linkage mechanism 11 with a handle 119 is driven, the secondary lock tongue drive block 1131 on it will pull or push the chain 122. The chain 122 drives the linkage gear 121 to rotate, thereby transmitting power to the linkage mechanism 11 on the adjacent side, realizing the linkage of the whole window and achieving the synchronous effect of "one driving multiple". The user only needs to operate one handle 119 to instantly complete the linkage locking or unlocking of all locking points around the door and window. The operation is extremely convenient and ensures the synchronicity of the actions of all locking points.

[0033] like Figure 1-8 As shown, in some embodiments, the interlocking mechanism 11 further includes a secondary gear 117 rotatably disposed inside the movable window sash 2 and located on both sides of the main gear 1112, and the opposite surfaces of the secondary locking tongue linkage rod 113 and the auxiliary linkage rod 114 are provided with secondary gear sets 118 that mesh with both sides of the secondary gear 117 respectively.

[0034] Between the two linkages driven by the main gear 1112, a secondary gear set 118 meshing with the secondary gear 117 is added. This makes the secondary locking tongue linkage 113 not only driven by the main gear 1112 in the middle, but also driven by the secondary gear 117 in other positions. This transforms the "concentrated point load" of the main gear 1112 on the long secondary locking tongue linkage 113 into a "distributed line load" supported by multiple secondary gears 117. This greatly improves the rigidity and stability of the long secondary locking tongue linkage 113 during the movement, effectively prevents its bending deformation, reduces vibration, noise and wear, and makes the transmission smoother and more reliable.

[0035] like Figure 1-8 As shown, in some embodiments, the fixed window sash 3 is provided with a plurality of main lock holes 31 and secondary lock holes 32, and the plurality of main lock holes 31 and secondary lock holes 32 correspond one-to-one with the positions of the main lock 111 and the secondary lock tongue 112 on the movable window sash 2.

[0036] On the fixed window sash 3, lock holes are precisely made corresponding to the positions of all the main locks 111 and secondary lock tongues 112 on the movable window sash 2, ensuring that each locking point can accurately act on the window frame to form an effective lock. This is the basic structural guarantee for achieving efficient and reliable multi-point locking function.

[0037] like Figure 1-8 As shown, in some embodiments, two limiting pins 1113 are provided on one side of the main lock 111, and a limiting rod 1114 is provided on the transmission rod 1111 of the main lock 111, with one end extending between the two limiting pins 1113. A handle 119 is provided on one end of the transmission rod 1111 of the main lock 111.

[0038] By using the limit pin 1113 and the limit rod 1114, the rotation angle of the transmission rod 1111 of the main lock 111 is limited, thereby defining the two precise positions of the main lock 111: "open" and "locked". Only one main lock 111 is connected to the handle 119, which serves as the sole power input point for the entire system. The limiting structure prevents the user from excessively rotating the handle 119 and damaging the internal transmission components, thus improving the product's durability and handling feel. The single handle 119 design simplifies user operation.

[0039] The interlocking mechanism 11 is configured to be driven by a 90-degree rotational force; the main lock 111 is configured as a rotary locking point, which can perform a 90-degree rotational movement under the drive of the 90-degree rotational force to achieve locking or unlocking. The specific implementation of the main lock 111 can be various, such as a hook lock, a rotary locking point, a mushroom head locking point, a cam lock, etc., as long as its basic working logic is "rotation of 90 degrees can achieve the function".

[0040] In summary, by setting up a transmission system consisting of interlocking mechanism 11 and linkage mechanism 12, the 90-degree rotational motion of a single handle 119 is efficiently converted into synchronous linkage of the main lock 111 and the secondary lock tongue 112 around the movable window sash 2. The design of the main gear 1112, multiple gears 117 drive and auxiliary linkage rod 114 significantly improves the transmission stability and avoids deformation and jamming of the secondary lock tongue linkage rod 113. The linkage mechanism 12 ensures that all locking points move synchronously. The overall structure is reasonably designed and easy to operate. While achieving efficient multi-point locking, it comprehensively improves the sealing, wind pressure resistance and safety performance of doors and windows.

[0041] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
