Description

Technical Field

[0001] This utility model relates to the technical field of door and window actuators, specifically to an integrated linkage actuator and a grain warehouse sealing window using the same. The device aims to automatically and reliably control the opening and closing of the window sash and its locking and unlocking in a preset sequence through a single linear motion of a single linear actuator. Background Technology

[0002] In the existing technology, the electric drive side shaft rotating grain silo sealing window is usually equipped with two independent actuators to perform the opening and closing and locking actions of the window sash respectively. This separate solution has the following inherent defects.

[0003] Firstly, the opening and closing of window sashes generally employs a "direct-drive" actuator, meaning the window sash shaft is directly driven by a motor reducer. Its drawbacks are at least twofold: Firstly, it has poor wind pressure resistance and a high load on the drive system. When the window sash is subjected to wind load, its opening and closing resistance torque increases sharply, forcing the motor reducer to provide a very large output torque. This necessitates the selection of a high-torque geared motor, which not only significantly increases equipment costs but also causes a substantial increase in operating energy consumption. Secondly, insufficient effective clamping force at the end makes it difficult for the window sash to close completely. A sealing strip is installed around the inner perimeter of the window sash. Closing the window requires overcoming the resistance of this sealing strip to compress and deform it, forming a continuous and reliable airtight barrier around the entire perimeter. Under a fixed rated output torque, the actual output torque of the motor is determined by the load, which in turn depends on the reaction force of the sealing strip on the window sash. This force is opposite to the tangential direction of the window sash's rotation and constitutes the main resistance during the closing process. Since the window sash has a single-sided rotating shaft structure, the farther the sealing strip is from the shaft, the greater the resistance torque that needs to be overcome when closing the window. Especially in the side areas of the window sash far from the shaft, the motor output torque required to compress the sealing strip increases significantly. Only by using a high-torque geared motor can sufficient thrust be provided at the end of the window closing process to completely close the window sash to the predetermined position and evenly and fully compress the sealing strip.

[0004] Secondly, the opening and closing of window sashes typically employs a rack and pinion mechanism controlled by a separate drive motor. This means that another drive motor provides rotational torque, which is then converted into linear motion via the rack and pinion to drive the latch to perform the opening and closing action. Its drawback is: Firstly, achieving high thrust output significantly increases the cost and energy consumption of the drive system. In the final stage of window sash locking, the latch needs to apply a large thrust along the tangent of the window sash's rotational motion to push it against the window frame, fully closing the sash and compressing the sealing strip. Since the output thrust of the gear-rack mechanism is directly related to the input torque, a high-torque geared motor must be configured to meet the aforementioned thrust requirements, resulting in a substantial increase in equipment cost and energy consumption. Secondly, there are significant reliability risks when providing high thrust. In the final stage of the locking process, if significant resistance is encountered, the drive motor needs to continuously output high torque, which can easily cause overheating and burn out due to overload. Once this happens, it will directly lead to the failure of the entire locking system.

[0005] Furthermore, the two sets of actuators for opening and closing the window sash and for locking and unlocking are completely independent, which inevitably leads to a complex overall structure, a large number of components, high manufacturing costs, and cumbersome control logic.

[0006] Therefore, there is an urgent need in this field for an innovative integrated technical solution that can fundamentally optimize the transmission path, eliminate the reliance on high-torque geared motors, and solve the problems of window sash opening and closing and reliable locking and sealing through an integrated linkage design with a more efficient, streamlined and reliable mechanism. Utility Model Content

[0007] Based on the deficiencies in the aforementioned background technology, the purpose of this utility model is to provide an integrated linkage execution device and a grain warehouse sealing window using the same, aiming to fundamentally solve a series of problems caused by the separation of the execution mechanisms for the window sash opening and closing action and the locking and unlocking action in the existing technology.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an integrated linkage execution device, including a linear driver, a locking mechanism, an opening and closing mechanism, and a transmission mechanism, wherein the linear driver is simultaneously linked with the locking mechanism and the opening and closing mechanism through the transmission mechanism; The transmission mechanism is configured to decompose a single unidirectional linear motion of the linear driver into sequential driving of the locking mechanism and the opening / closing mechanism; during the closing process, the opening / closing mechanism is driven to the closed position first, and then the locking mechanism is driven to the locked position; during the opening process, the locking mechanism is driven to the unlocked position first, and then the opening / closing mechanism is driven to the open position.

[0009] As a limitation of this utility model, the transmission mechanism includes a first delay transmission component and a second delay transmission component; The first delay transmission member is driven between the linear driver and the opening / closing mechanism, and has a first free stroke; the second delay transmission member is driven between the linear driver and the locking mechanism, and has a second free stroke. The first idle stroke and the second idle stroke are configured to alternately engage and disengage power transmission during a single unidirectional linear motion of the linear actuator, thereby achieving sequential driving of the locking mechanism and the opening / closing mechanism.

[0010] As a further limitation of this utility model, the first delay transmission component includes a pusher frame and a first push-pull rod; The pusher frame is slidably assembled into the housing of the opening and closing mechanism along a preset trajectory; The first push-pull rod is linked to the linear actuator and slides along the push frame; A first positioning pin is fixedly provided on the first push-pull rod; a first slide groove extending along its sliding direction is correspondingly provided on the push frame, and the first positioning pin is slidably assembled in the first slide groove. The sliding stroke of the first positioning pin within the first groove constitutes the first empty stroke.

[0011] As a further definition of this utility model, the first groove has a first stroke end point and a second stroke end point; A first compression spring in a compressed state is fitted between the first push-pull rod and the push frame. The first compression spring applies a force to the push frame so that the first stroke end point has a tendency to maintain constant contact with the first positioning pin. When the first positioning pin remains in contact with the first stroke end point, the linear actuator drives the opening and closing mechanism through the first delay transmission component; When the first positioning pin moves between the first stroke endpoint and the second stroke endpoint, the linear drive drives the locking mechanism through the second delay transmission member.

[0012] As a further limitation of this utility model, the pusher frame is provided with a second slide groove perpendicular to the first slide groove; It also includes a locking component for locking the first positioning pin; the locking component includes: A retainer is fixed to the housing. The retainer is provided with a guide groove, which includes a long slide and a rotary slide communicating with the long slide. The locking plate has a third sliding groove through which the first positioning pin passes. A locking rod is fixed on the lower surface of the locking plate, and at least two positioning pins are fixed on the upper surface. The locking rod is slidably assembled in the second sliding groove, and all the positioning pins are slidably assembled in the guide groove. A tension spring, connected between the locking rod and the push frame, is used to provide a pulling force to the locking rod that tends to pull the locking plate toward the unlocked position; When all the positioning pins are located in the long slide, the locking piece is in the locked position. At this time, the extension direction of the third slide groove is perpendicular to the extension direction of the first slide groove, so as to prevent the first positioning pin from sliding in the first slide groove. When one of the positioning pins falls into the rotating slide, the locking plate is in the unlocked position. At this time, the locking plate can swing back and forth relative to the push frame, providing a channel for the first positioning pin to slide in the first slide groove, thereby performing the first empty stroke.

[0013] As a further limitation of this utility model, the opening and closing mechanism includes a rack and a gear that mesh with each other; the rack is fixedly installed on the pusher frame, and the gear is used to be fixedly installed on the window sash shaft.

[0014] As a further limitation of this utility model, the second delay transmission component includes a second push-pull rod and a first motion direction conversion component; The first motion direction conversion component includes a first mounting bracket, a third push-pull rod slidably mounted on the first mounting bracket, and a first swing plate rotatably mounted on the first mounting bracket. The first swing plate is linked with the third push-pull rod and the locking mechanism respectively, and is used to convert the linear motion of the third push-pull rod into the reciprocating linear motion that drives the locking mechanism. An elastic reset member is provided between the third push-pull rod and the first mounting bracket for providing a reset force to the third push-pull rod; The second push-pull rod is linked to the linear actuator and slidably connected to the third push-pull rod; The relative sliding stroke between the second push-pull rod and the third push-pull rod constitutes the second free stroke.

[0015] As a further limitation of this utility model, the locking mechanism includes at least one locking tongue assembly; the locking tongue assembly includes a locking tongue bracket, a transmission link and at least one actuating component; The transmission link is slidably mounted on the locking tongue frame and is linked with the first swing plate to receive linear driving force; The actuating components include a second swing plate rotatably mounted on the latch frame and a latch slidably mounted on the latch frame; The second swing plate is linked with the latch and the transmission link respectively, and is used to convert the linear driving force received by the transmission link into a linear force perpendicular to the linear driving force, so as to drive the latch to perform an extension or retraction movement.

[0016] As a further limitation of this utility model, the locking mechanism includes at least two of the latch assemblies, and the at least two latch assemblies are configured to be hidden and distributed on adjacent or opposite sides of the window sash. The latch assemblies distributed on different sides are linked together by a second motion direction conversion assembly; The second motion direction conversion assembly includes a second mounting bracket and a third swing plate rotatably mounted on the second mounting bracket; the third swing plate is linked with the transmission linkage of the latch assembly on different sides to convert the direction of the linear driving force received by one latch assembly and transmit it to the adjacent latch assembly.

[0017] This utility model also provides a grain warehouse sealing window, including a window frame and a window sash that can be opened and closed and installed on the window frame, and also includes the integrated linkage actuator as described above; The integrated linkage actuator is installed on the window frame and is used to drive the window sash to perform opening and closing actions and locking and unlocking actions relative to the window frame.

[0018] By adopting the above-mentioned technical solution, the beneficial effects achieved by this utility model compared with the prior art are as follows: (1) This utility model provides a novel linkage actuator that can be widely used in applications requiring high sealing performance, such as grain warehouse sealed windows, insulated airtight doors, and grain warehouse ventilation openings. This device, employing a single linear actuator, achieves integrated control of the opening and closing, as well as the locking and unlocking actions of the window (or door) sash, completely eliminating the design concept of requiring two independent actuators in the traditional electric drive side-shaft swing-out scheme. This integrated design reduces the use of drive components, effectively lowers manufacturing costs and the complexity of the control system logic, significantly improves the reliability of equipment operation, and provides a superior solution for the opening, closing, locking and unlocking control of grain warehouse sealed windows, insulated airtight doors, and grain warehouse ventilation openings.

[0019] (2) This utility model uses a linear actuator (such as an electric actuator or a hydraulic actuator) as a single drive source. This type of actuator can provide a much larger thrust than traditional drive motors, easily meeting the huge thrust required for opening, closing and locking the sealed window. Secondly, the linear actuator has a simple structure, and under the condition of providing the same thrust, its cost is lower than that of a drive motor, and its drive power requirement is smaller, thus significantly reducing equipment costs and operating energy consumption. In addition, the linear actuator is less prone to motor burnout due to overload or jamming, greatly improving its operational reliability.

[0020] (3) This utility model achieves the mandatory sequential action of "closing the window first and then locking it" and "unlocking the window first and then opening it" through the innovative pure mechanical structure design of the first and second delay transmission components. This mechanical structure-based sequential control logic completely avoids the risks of program errors and sensor failures that may occur in the electronic control system, and ensures the absolute accuracy of the action execution and the reliability of the system.

[0021] (4) In the first delay transmission component, this utility model forms a unique double-locking stable structure by cleverly setting the first compression spring and locking component. When performing the opening and closing action of the window sash, this design can lock the position of the first positioning pin, preventing the first positioning pin from sliding unexpectedly in the first slide groove. This allows the window sash to effectively resist external interference such as wind load when opening and closing, maintain the stability of the window sash, avoid violent shaking of the window sash, and greatly improve the system's adaptability under adverse weather conditions.

[0022] (5) This utility model constructs a complete circumferential balanced pressing system by rationally distributing multiple locking tongue components on each side of the window frame. This distributed layout ensures the uniform distribution of pressing force around the window sash, enabling the entire sealing strip to obtain a consistent and sufficient amount of compression, completely eliminating the sealing dead angle problem caused by traditional single-point or few-point pressing methods; secondly, this distributed design allows the pressing load to be evenly distributed, effectively avoiding local stress concentration, significantly improving the reliability of the sealing system, and extending the service life of the sealing strip; in addition, multi-point coordinated pressing can effectively compensate for the adverse effects caused by manufacturing tolerances, installation errors, and long-term deformation of the window sash or window frame, ensuring that the sealing system can maintain a stable and reliable sealing effect under various working conditions. This scientific layout scheme not only achieves reliable sealing in all directions, but also greatly improves the fatigue resistance and long-term stability of the system.

[0026] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0027] Example 1: An integrated linkage execution device This embodiment is applicable to grain silo sealing windows, grain silo insulated airtight doors, or grain silo ventilation openings where strict sealing performance is required. For example... Figure 1 As shown, this embodiment includes a linear actuator 1, a locking mechanism 2, an opening and closing mechanism 3, and a transmission mechanism 4. The linear actuator 1 is preferably an electric push rod, which achieves mechanical linkage with both the locking mechanism 2 and the opening and closing mechanism 3 through the transmission mechanism 4.

[0028] I. Transmission Mechanism 4 The transmission mechanism 4 is configured to decompose a single unidirectional linear motion of the linear actuator 1 into a sequential drive of the locking mechanism 2 and the opening / closing mechanism 3. Specifically, during the closing process, the opening / closing mechanism 3 is driven to the closed position first, and then the locking mechanism 2 is driven to the locked position; during the opening process, the locking mechanism 2 is driven to the unlocked position first, and then the opening / closing mechanism 3 is driven to the open position.

[0029] like Figure 2 As shown, the transmission mechanism 4 includes a first delayed transmission component 7 and a second delayed transmission component 8. The first delayed transmission component 7 is driveably connected between the linear actuator 1 and the opening / closing mechanism 3, forming a linkage path between the linear actuator 1 and the opening / closing mechanism 3, and has a preset first idle stroke. The second delayed transmission component 8 is driveably connected between the linear actuator 1 and the locking mechanism 2, forming a linkage path between the linear actuator 1 and the locking mechanism 2, and has a preset second idle stroke. These two idle strokes are configured to alternately engage and disengage power transmission during one unidirectional linear motion of the linear actuator 1, thereby achieving precise sequential drive. Specifically, during one unidirectional linear motion of the linear actuator 1, when the first idle stroke engages power transmission, the linear actuator 1 drives the locking mechanism 2 to operate, but does not drive the opening / closing mechanism 3; when the second idle stroke engages power transmission, the linear actuator 1 drives the opening / closing mechanism 3 to operate, but does not drive the locking mechanism 2.

[0030] (1) First delay transmission component 7 The first delayed transmission component 7 includes a pusher frame 101 and a first push-pull rod 102. For example... Figure 3 and Figure 4 As shown, the pusher frame 101 is slidably mounted within the housing 104 of the opening and closing mechanism 3 via the first guide rail 103, and can move smoothly along a preset trajectory. In this embodiment, the moving direction of the pusher frame 101 is consistent with the linear motion direction of the output end of the linear actuator 1. The first end of the first push-pull rod 102 is connected to the output end of the linear actuator 1, and the second end is slidably mounted on the pusher frame 101. In this embodiment, the first push-pull rod 102 is slidably mounted on the pusher frame 101 via a bushing.

[0031] A first positioning pin 105 is fixedly provided on the second end of the first push-pull rod 102, and a first slide groove 106 extending along its sliding direction is correspondingly provided on the push frame 101. The first positioning pin 105 is slidably assembled in the first slide groove 106, and its sliding stroke in the first slide groove 106 constitutes the first idle stroke. In this embodiment, the first idle stroke is equal to the effective working stroke of the second delay transmission member 8. That is, when the first positioning pin 105 slides in the first slide groove 106 and performs the first idle stroke, it is the time window when the locking mechanism 2 is driven.

[0032] like Figure 3 and Figure 4 As shown, the first slide 106 has a first stroke endpoint (right end point in the figure) and a second stroke endpoint (left end point in the figure). A first compression spring 107 in a compressed state is fitted between the first push-pull rod 102 and the push frame 101. The first compression spring 107 continuously applies a force to the push frame 101, causing the first stroke endpoint to have a tendency to maintain constant contact with the first positioning pin 105. When the first positioning pin 105 is in contact with the first stroke endpoint, the linear actuator 1 drives the opening and closing mechanism 3 through the first delay transmission member 7; when the first positioning pin 105 moves between the first stroke endpoint and the second stroke endpoint, the first delay transmission member 7 performs a first idle stroke, and the linear actuator 1 drives the locking mechanism 2 through the second delay transmission member 8.

[0033] Furthermore, such as Figure 3 and Figure 4 As shown, the pusher frame 101 has a second slide groove 108 that is perpendicular to the first slide groove 106.

[0034] This embodiment also includes a locking component for locking the first positioning pin 105 in position, preventing it from sliding in the first slide groove 106. For example... Figures 5 to 8 As shown, the locking assembly includes a retainer 109, a locking plate 110, and a tension spring (not shown in the figures). The retainer 109 is fixed to the housing 104 of the opening and closing mechanism 3, as shown. Figure 5As shown, the retainer 109 is provided with a guide groove 111, which includes a long slide 112 and a rotating slide 113 connected together. In this embodiment, the long slide 112 is specifically a long hole, the length direction of which is consistent with the moving direction of the pusher 101. The rotating slide 113 is specifically a fan-shaped through hole.

[0035] The locking plate 110 is a rectangular piece with a third groove 114 through which the first positioning pin 105 passes. A locking rod 115 is fixed to its lower surface, and at least two positioning posts 116 are fixed to its upper surface. In actual manufacturing, the locking rod 115 typically passes through the locking plate 110, with the portion of the locking rod 115 extending to the upper surface of the locking plate 110 constituting one of the positioning posts 116. The locking rod 115 is slidably fitted within the second groove 108, and all positioning posts 116 are slidably fitted within the guide groove 111. A tension spring connects the locking rod 115 to the pusher frame 101, providing a pulling force to the locking rod 115 that tends to pull the locking plate 110 towards the unlocked position (i.e., pulling the locking rod 115 towards the end of the second groove 108 away from the first groove 106). In this embodiment, two positioning posts 116 are fixed to the upper surface of the locking plate 110 to accommodate the rotating slide 113. Specifically, as shown... Figure 5 As shown, when the locking rod 115 is pulled toward the end of the second slide groove 108 away from the first slide groove 106, one of the positioning pins 116 falls into the center of the rotating slide 113, and the other positioning pin 116 can move along the arc edge of the rotating slide 113, so as to realize the swing of the locking plate 110 relative to the push frame 101.

[0036] The working principle of the locking component is as follows: Figure 7 and Figure 8 As shown, when all the positioning pins 116 are located within the elongated slide rail 112, the locking piece 110 is in the locked position. At this time, the extension direction of the third slide groove 114 is perpendicular to the extension direction of the first slide groove 106, effectively preventing the first positioning pin 105 from sliding within the first slide groove 106. Simultaneously, the first push-pull rod 102 forms a mechanical linkage with the push frame 101, driving the opening and closing mechanism 3 to operate. When the first push-pull rod 102 drives the push frame 101 to operate, the positioning pins 116 will slide within the elongated slide rail 112.

[0037] It should be noted that the length of the elongated slide 112 is designed to accommodate the effective working stroke required for the first delayed transmission component 7 to drive the opening and closing mechanism 3 to complete one full opening or closing action of the window. When the positioning post 116 of the locking plate 110 slides from one end to the other within the elongated slide 112, the pusher 101 can move a sufficient distance to drive the window sash 5 from the fully closed state to the fully open state, or vice versa, via the opening and closing mechanism 3.

[0038] like Figure 5 and Figure 6As shown, when all the positioning pins 116 are located in the rotating slide 113, the locking piece 110 is in the unlocked position. At this time, the locking piece 110 can swing relative to the push frame 101 to continuously change the relative overlap position of the third slide 114 and the first slide 106, providing a channel for the first positioning pin 105 to slide in the first slide 106, thereby performing the first idle stroke.

[0039] It should be noted that the length of the arcuate edge of the rotary slide 113 is designed to accommodate the range of motion required for the first delayed transmission member 7 to perform a complete first idle stroke. This design ensures that the swing angle of the locking piece 110 is precisely controlled when the positioning pin 116 of the locking piece 110 slides along the arcuate edge within the rotary slide 113. This allows the changing trajectory of the relative overlap between the third slide groove 114 and the first slide groove 106 to generate sufficient channel space, allowing the first positioning pin 105 to complete its entire sliding stroke within the first slide groove 106 from the first stroke endpoint to the second stroke endpoint (or vice versa).

[0040] (2) Second delay transmission component 8 The second delay transmission component 8 includes a second push-pull rod 201 and a first motion direction conversion assembly. For example... Figure 9 and Figure 10 As shown, the first motion direction conversion assembly includes a first mounting bracket 202, a third push-pull rod 205 slidably mounted on the first mounting bracket 202, and a first swing plate 203 rotatably mounted on the first mounting bracket 202.

[0041] The first swing plate 203 is linked to the third push-pull rod 205 and the locking mechanism 2, respectively, to convert the linear motion of the third push-pull rod 205 into the linear motion driving the locking mechanism 2. Specifically, the first swing plate 203 has a triangular plate-like structure, with one corner rotatably connected to the first mounting bracket 202, the second corner slidably assembled with the third push-pull rod 205, and the third corner slidably assembled with the transmission connecting rod 402 in the locking mechanism 2. Figure 9 As shown, a first elongated hole is provided at the second corner of the first swing plate 203, and a first pin is provided at the end of the third push-pull rod 205. The first pin is slidably assembled in the first elongated hole to realize the sliding assembly of the first swing plate 203 and the third push-pull rod 205. A second elongated hole is provided at the third corner of the first swing plate 203, and a second pin is provided at the end of the transmission link 402 of the locking mechanism 2. The second pin is slidably assembled in the second elongated hole to realize the sliding assembly of the first swing plate 203 and the transmission link 402.

[0042] Furthermore, an elastic reset element is provided between the third push-pull rod 205 and the first mounting bracket 202. In this embodiment, the elastic reset element is a second compression spring 204, which is used to provide a reset force to the third push-pull rod 205 to ensure that the third push-pull rod 205 can stably return to its original position when there is no external force driving it (i.e. when the second push-pull rod 201 retracts).

[0043] The second push-pull rod 201 is linked to the linear actuator 1 and slidably connected to the third push-pull rod 205. Specifically, the free end of the second push-pull rod 201 is provided with an axial hole, and the corresponding end of the third push-pull rod 205 extends into the axial hole. The relative sliding stroke between the second push-pull rod 201 and the third push-pull rod 205 constitutes the second idle stroke. In this embodiment, the second idle stroke is equal to the effective working stroke of the first delay transmission member 7. That is, when the second push-pull rod 201 and the third push-pull rod 205 slide relative to each other and execute the second idle stroke, it is precisely the time window when the opening and closing mechanism 3 is driven.

[0044] II. Opening and closing mechanism 3 The opening and closing mechanism 3 is responsible for converting the linear motion transmitted by the transmission mechanism 4 into the rotary opening and closing action of the window sash 5. In this embodiment, the opening and closing mechanism 3 includes a rack 301 and a gear 302 that mesh with each other. The rack 301 is fixedly installed on the aforementioned push frame 101 and moves linearly together with the push frame 101; the gear 302 is fixedly installed on the rotating shaft of the window sash 5 by a key connection or interference fit.

[0045] When the pusher 101 is driven by the first delayed transmission member 7 to generate linear displacement, the rack 301 fixed on it moves synchronously. The meshing action of the rack 301 and the gear 302 converts the linear motion into the rotational motion of the gear 302, which in turn drives the window sash 5 to complete the opening or closing action through the window sash 5 shaft.

[0046] In this embodiment, the length of the rack 301 is matched with the effective stroke of the pusher 101, and the pitch circle diameter of the gear 302 is precisely calculated according to the required opening and closing angle of the window sash 5. This design ensures that the window sash 5 can reliably rotate within a predetermined angle range from fully closed to fully open throughout the entire working stroke of the pusher 101.

[0047] The timing of the opening and closing mechanism 3 is precisely controlled by the first delayed transmission member 7. Specifically, the power of the linear actuator 1 is transmitted to the opening and closing mechanism 3 through the pusher frame 101 only when the first positioning pin 105 is in contact with the first stroke end point of the first slide 106. During the operation of the locking mechanism 2 (i.e., the first idle stroke stage), the opening and closing mechanism 3 remains stationary, thereby realizing the forced sequential action of "closing the window before locking" and "unlocking the window before opening".

[0048] III. Locking Mechanism 2 The locking mechanism 2 is used to apply pressure to the window sash 5 after it is closed, ensuring that the sealing strip on the inner side of the window sash 5 is fully compressed to achieve a reliable seal. The locking mechanism 2 includes at least one latch assembly. In practical applications, it can be flexibly configured according to the size of the window sash 5, the sealing level requirements, and cost considerations: a latch assembly can be set on one side of the window sash 5 (usually the free side opposite the pivot); or a latch assembly can be arranged on all four sides of the window sash 5 to form a balanced pressure around the circumference of the window sash 5.

[0049] like Figures 11 to 13 As shown, each latch assembly includes a latch bracket 401, a transmission link 402, and at least one actuating component (i.e., one or more actuating components can be provided on one side). The transmission link 402 is linked with the actuating component. It typically also includes a lock seat for use. When locking is required, the transmission link 402 drives the latch 404 to extend and enter the lock seat; when unlocking is required, the transmission link 402 drives the latch 404 to retract from the lock seat.

[0050] The latch bracket 401 serves as the basic mounting frame and is fixed within the window frame 6. The transmission link 402 is slidably mounted on the latch bracket 401; in this embodiment, the transmission link 402 is slidably mounted on the latch bracket 401 via a bushing. One end of the transmission link 402 is linked to the first swing plate 203 in the aforementioned second delay transmission component 8 (specifically, through a second pin slidingly engaging with the second elongated hole on the first swing plate 203) to receive linear driving force.

[0051] Each actuating component includes a second swing plate 403 and a locking tongue 404. The second swing plate 403 is rotatably mounted on the locking tongue holder 401, and its function is to convert the linear driving force received by the transmission link 402 into a linear force perpendicular to the linear driving force, so as to drive the locking tongue 404 to perform an extension or retraction movement.

[0052] In this embodiment, the second swing plate 403 has a triangular plate-like structure, with one corner rotatably connected to the latch bracket 401 and the other two corners slidably connected to the latch bracket 401. Figures 11 to 13As shown, the locking tongue bracket 401 is provided with a first guide groove 405 and a second guide groove 406. The length direction of the first guide groove 405 is consistent with the movement of the transmission connecting rod 402, and the length direction of the second guide groove 406 is consistent with the movement direction of the locking tongue 404. One corner of the second swing plate 403 is rotatably connected to the latch bracket 401 via a shaft; the second corner is slidably engaged with the first guide groove 405 via a third pin, and is linked to the transmission connecting rod 402 via the third pin. Specifically, a third elongated hole is provided at the second corner position of the second swing plate 403, the bottom end of the third pin is fixedly connected to the transmission connecting rod 402, and extends vertically upward through the first guide groove 405 and into the third elongated hole of the second swing plate 403; the third corner is slidably engaged with the second guide groove 406 via a fourth pin, and is linked to the latch 404 via the fourth pin. Specifically, a fourth elongated hole is provided at the triangular position of the second swing plate 403, the top end of the fourth pin is connected to the latch 404, and extends vertically downward through the fourth elongated hole of the second swing plate 403 and into the second guide groove 406. Since the fourth elongated hole is blocked by the latch 404, it cannot be observed in the attached drawing.

[0053] To reduce friction, multiple ball bearings are embedded between the contact surfaces of the second swing plate 403 and the locking tongue bracket 401.

[0054] The locking tongue 404 is slidably mounted on the locking tongue bracket 401 via the second guide rail 407, the length direction of the second guide rail 407 being consistent with the direction of the linear force.

[0055] Working process: When the transmission linkage 402 is driven to make linear motion, it pushes the third pin to slide along the first guide groove 405, and at the same time drives the second swing plate 403 to swing counterclockwise around its axis. The swing of the second swing plate 403 then pushes the fourth pin through the fourth elongated hole. Since the fourth pin is confined in the second guide groove 406, the linear driving force is converted into a linear force with a different direction, driving the locking tongue 404 to extend along the second guide rail 407.

[0056] The unlocking process is the opposite. Under the action of linear driving force, the transmission link 402 moves in the opposite direction, which drives the second swing plate 403 to swing clockwise around its axis through the third pin, driving the lock tongue 404 to retract along the second guide rail 407.

[0057] In this embodiment, to synchronously drive multiple latch assemblies distributed on different sides, the embodiment also includes a second motion direction conversion assembly 408. The second motion direction conversion assembly 408 includes a second mounting bracket and a third swing plate rotatably mounted thereon. The structure of the third swing plate is similar to that of the first swing plate 203, exhibiting a triangular plate-like structure. One corner is hinged to the second mounting bracket, and the other two corners are respectively provided with elongated holes.

[0058] The ends of the transmission links 402 of the latch assemblies distributed on different sides (such as horizontal and vertical sides) are slidably assembled with the elongated holes at the corresponding corners of the third swing plate by means of pins.

[0059] Linkage Principle: Taking the driving of a horizontal lock tongue assembly and a vertical lock tongue assembly as an example. When the horizontal transmission link 402 is driven to make linear motion, the pin at its end slides in the elongated hole of the third swing plate, driving the third swing plate to swing around its hinge point. The swing of the third swing plate, in turn, drives the vertical transmission link 402 to make linear motion through another elongated hole, thereby converting the horizontal linear driving force by 90° and transmitting it to the vertical lock tongue assembly, realizing the synchronous linkage of the two vertical lock tongues 404. By combining multiple second motion direction conversion components 408, unified driving of all side lock tongue assemblies can be achieved.

[0060] Example 2: A grain warehouse sealing window like Figure 14 and Figure 15 As shown, the grain warehouse sealing window includes a window frame 6 and a window sash 5 that is openable and closable and installed on the window frame 6, and also includes an integrated linkage actuator as described in Embodiment 1.

[0061] The integrated linkage actuator is installed on the window frame 6 and is used to drive the window sash 5 to perform opening, closing and locking actions relative to the window frame 6. Specifically, the transmission mechanism 4, linear actuator 1 and opening / closing mechanism 3 of the integrated linkage actuator are installed above the window frame 6 and encapsulated in a housing, while the locking mechanism 2 is directly embedded in the cavity of the window frame 6.

[0062] This installation method creates a concealed installation, with all components hidden, resulting in a neat and aesthetically pleasing appearance. It also effectively prevents dust intrusion and human-caused damage, making it ideal for industrial environments such as grain silos.

[0063] Furthermore, the gear 302 in the opening and closing mechanism 3 is fixedly mounted on the rotating shaft of the window sash 5 by a key connection or interference fit. When the device receives a window closing command, the power of the linear actuator 1 is finally converted into the rotational torque of the rotating shaft of the window sash 5 through the transmission mechanism 4 and the opening and closing mechanism 3, driving the window sash 5 to rotate around its rotating shaft until it closes with the window frame 6.

[0064] On the window sash 5, at positions corresponding to the window frame 6, multiple lock seats are installed. Multiple latch assemblies of the locking mechanism 2 are distributed on various sides of the window frame 6 (such as top, bottom, left, and right), with the actuating end of its latch 404 facing the lock seat.

[0065] The specific working process of this embodiment is as follows: When the window sash 5 is closed, the linear actuator 1 is activated. Its one-way linear motion, pulled back once, is controlled sequentially by the transmission mechanism 4. First, it drives the opening and closing mechanism 3 to rotate the window sash 5 to the closed position. Then, it drives the locking mechanism 2 to extend each of the locking tongues 404 synchronously. The locking tongues 404 cooperate with the lock seat to finally press the window sash 5 firmly against the window frame 6, so that the sealing strip around the window sash 5 is evenly and fully compressed, achieving reliable airtightness and thermal insulation sealing. Figure 14 This shows the closed and locked state.

[0066] When the window sash 5 is opened, the linear actuator 1 is activated. Its one-way linear motion is controlled sequentially by the transmission mechanism 4. First, it drives all the latches 404 of the locking mechanism 2 to retract synchronously, releasing the locking of the window sash 5. Then, it drives the opening and closing mechanism 3 to rotate the window sash 5 to the open position. Figure 15 It shows the on and off state.
