Description

Technical Field

[0001] This invention relates to the field of smoke exhaust skylight technology, and more specifically, to the design of a smoke exhaust skylight locking function. Background Technology

[0002] The wind pressure resistance of smoke exhaust skylights is crucial for safety. In severe weather conditions such as typhoons, it's essential not only to protect the skylight from damage but also to safeguard internal facilities and even lives and property. Existing smoke exhaust skylights typically rely on the self-locking force of a motor to meet wind pressure resistance requirements. This places high demands on the motor's self-locking force. Especially for larger skylights, ensuring secure locking is a pressing issue. Therefore, selecting a purely mechanical locking mechanism, avoiding the motor component, and implementing multiple locking points are important safety measures. Summary of the Invention

[0003] To address the aforementioned technical problems, this invention employs a multi-point self-locking structure to ensure the self-locking force of the smoke exhaust skylight when it is closed, thereby guaranteeing safety.

[0004] To achieve the above objectives, the present invention provides a multi-point self-locking smoke exhaust skylight, comprising a window sash hinged to a window frame; multiple structural reinforcement struts are horizontally arranged on the inner side of the window sash from the hinged side to the opening side. On the opening side of the window sash, a multi-section drive shaft is provided through each of the struts and rotates synchronously; multiple locking fingers are spaced along the drive shaft; the drive shaft is the rotation center of the fingers. The window sash is provided with an electric push rod for opening and closing the window sash, the head of the electric push rod being hinged to a strut groove of one of the struts of the window sash via a first pin, the first pin also passing through one end of the drive rod, the other end of the drive rod being hinged to one end of one of the fingers via a third pin; the other end of the finger is a hook-shaped structure, and the window frame is provided with locking contacts corresponding to each of the fingers for locking the hook-shaped structure.

[0005] In a preferred embodiment, the drive shaft is composed of multiple long and short shafts connected by connectors. The first pin also hooks a spring, the other end of which is hooked onto a second pin fixed to the central support of the window sash. The electric push rod is fixed to the window frame via a central hinge component. The hinge end of the window sash is lower than or level with the top of the lock where the lock is located.

[0006] First, this invention incorporates multiple locks on the smoke exhaust skylight sash to ensure reliable locking. Second, it integrates a mechanical self-locking structure into the skylight's transmission mechanism. This mechanical self-locking structure, working in conjunction with the transmission mechanism, not only effectively improves the skylight's wind pressure resistance but also reduces the likelihood of motor failure due to excessive load. This invention allows the smoke exhaust skylight to meet wind pressure resistance requirements while also providing anti-theft functionality. Attached Figure Description

[0014] like Figures 1-7 As shown, the mechanical self-locking structure of the smoke exhaust skylight of the present invention mainly includes a first pin 1, a second pin 2, a third pin 3, a transmission shaft 4, a spring 5, a transmission rod 8, a finger piece 9, and a locking device 10.

[0015] On the opening side of the window sash, a multi-section drive shaft 4 is provided through each of the central supports 66 and rotates synchronously; multiple window locking fingers 9 are spaced apart on the drive shaft 4.

[0016] In the preferred embodiment, the first and second pins have the same dimensions. The first pin is placed in the pre-designed and machined center support groove 11 (located on the window sash frame), connecting and fixing the head of the motor push rod 7 (the motor, labeled 6), the tail end of the transmission rod 8, and the tail end of the spring 5. The second pin 2 is placed in a pre-machined hole, connecting and fixing the head of the spring. The third pin 3 passes through the pre-drilled holes of the transmission rod 8 and one of the finger pieces 9, connecting and fixing the transmission rod 8 and one of the finger pieces 9. The transmission shaft 4 passes through the window sash center support and the finger piece, constraining the movement trajectory of the finger piece and serving as the rotation center of the finger piece. The two ends of the spring are connected to the first pin 1 and the second pin 2 respectively, preventing the first pin 1 from moving to the lower end of the groove under strong winds during the opening and closing process of the skylight, thus preventing the skylight from closing properly. The transmission rod 8 is the main part of the mechanical self-locking structure, connecting to the transmission mechanism so that the mechanical self-locking structure can cooperate with the transmission mechanism, and the connected parts can work together. Finger 9 is connected to transmission rod 8 via third pin 3 and is constrained in movement by transmission shaft 4. With the coordinated movement of transmission rod 8 and transmission mechanism, locking and unlocking actions can be completed. Locking receiver 10 is fixed to the smoke exhaust sunroof by fasteners. When finger 9 engages in locking, locking receiver 10 cooperates with finger 9 to increase the locking force of the sunroof. Figure 6 and 7 As shown, the drive shaft 4 is composed of multiple long shafts 61 and short shafts 64 connected by a connector 62.

[0017] The self-locking structure of this invention can be used in any structure such as the skylight described above, and the self-locking structure involved is completely consistent with the one described above. An example of the working principle and process is shown in the figure.

[0018] When the skylight is completely closed, the skylight situation is as follows: Figure 1 At this time, the first pin 1 moves to the lower end of the middle support groove 11 under the drive of the transmission mechanism. The transmission rod 8 drives the finger 9 to rotate around the transmission shaft 4 under the constraint of the third pin 3. During the rotation, the finger 9 cooperates with the lock 10 to complete the locking action, thereby increasing the overall self-locking force and wind pressure resistance of the sunroof.

[0019] When the skylight is fully closed and the sash is just about to be lifted, the skylight's condition is as follows: Figure 2 At this time, the first pin 1 moves to the upper end of the central support groove 11 under the drive of the transmission mechanism. Driven by the first pin 1, the transmission rod drives the finger 9 to rotate around the transmission shaft 4 under the constraint of the third pin 3. During the rotation, the finger 9 cooperates with the lock 10 to complete the unlocking action, so that the sunroof can be opened normally.

[0020] When the skylight is being raised from the moment the window sash is about to be fully raised, the skylight's condition is as follows:Figure 3 At this time, pin 1, driven by the transmission mechanism and pulled by spring 5, is always located at the upper end of the central support groove 11. Under the constraint of the first pin 1, the transmission rod 8 also constrains the finger piece 9 connected to the transmission rod 8, and the finger piece 9 always remains in the "unlocked" state.

[0021] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
