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] For smoke exhaust skylights, wind pressure resistance is a crucial indicator for ensuring their safe use. If a smoke exhaust skylight fails to meet wind pressure resistance standards, it will not only be damaged during severe weather events such as typhoons, but also damage internal building facilities, threatening people's lives and property. Currently, smoke exhaust skylights generally rely on the self-locking force of their own transmission mechanism to meet wind pressure resistance requirements. This means they depend on the self-locking force when the motor is fully retracted to maintain the stability of the closed skylight and its overall wind pressure resistance.

[0003] Existing smoke exhaust skylights typically rely on the self-locking force of the motor to meet the wind pressure resistance requirements. In this case, the higher the wind pressure resistance requirement, the higher the self-locking force required by the motor, thus increasing production costs. Secondly, when smoke exhaust skylights encounter strong winds and severe weather, relying solely on the motor's self-locking force to maintain stability will place a significant load on the motor, potentially causing damage. Finally, in extreme weather conditions such as typhoons or hurricanes, some skylights equipped with motors possessing insufficient self-locking force may be damaged due to inadequate wind pressure resistance, leading to damage to building interiors and threatening people's lives and property. Summary of the Invention

[0004] To address the aforementioned technical issues, a mechanical self-locking structure was designed to enhance the overall self-locking force of the sunroof.

[0005] To achieve the above objectives, the present invention provides a smoke exhaust skylight based on a mechanical self-locking structure, comprising a window sash hinged to a window frame via hinges; the window sash is equipped with an electric push rod for opening and closing the window sash. The top end of the electric push rod is hinged to a central support groove in the window sash or a structural groove on the edge of the window sash via a pin A. The pin also passes through one end of a transmission rod, and the other end of the transmission rod is connected to a finger via a rotating shaft C. The middle of the finger serves as the rotation center, and a pin D is connected to the central support of the window sash. The other end of the finger relative to the rotating shaft C has a hook-shaped structure, and a corresponding locking device for locking the hook-shaped structure is provided on the window frame.

[0006] In a preferred embodiment, pin A is further hooked with a spring, the other end of which is hooked to pin B, which is 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.

[0007] The central brace refers to the reinforcing structure in the middle of the window sash of this invention, which can be located in the middle or slightly off-center of the window sash. Alternatively, the structure can be located on the edge of the window sash, achieving the same effect as the central brace, and thus constitutes an equivalent substitution in this invention.

[0008] This invention incorporates a mechanical self-locking structure into the transmission mechanism of the smoke exhaust skylight. This self-locking structure, working in conjunction with the transmission mechanism, not only effectively improves the wind pressure resistance of the smoke exhaust skylight 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

[0012] Figure 4 yes Figure 2 A magnified schematic diagram of a portion of the structure. Detailed Implementation

[0013] like Figures 1-4As shown, the mechanical self-locking structure of the smoke exhaust skylight of this invention mainly includes an A pin 1, a B pin 2, a C rotating shaft 3, a D pin 4, a spring 5, a transmission rod 8, a finger piece 9, and a locking device 10. Pins A and B have the same dimensions. Pin A is placed in a 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 (labeled 6 is the motor of the push rod), the tail end of the transmission rod 8, and the tail end of the spring 5. Pin B 2 is placed in a pre-machined hole, connecting and fixing the head of the spring. The C rotating shaft 3 passes through the reserved holes of the transmission rod 8 and the finger piece 9, connecting and fixing the transmission rod 8 and the finger piece 9. Pin D 4 passes through the window sash center support and the finger piece, constraining the movement trajectory of the finger piece. The two ends of the spring are connected to pins A 1 and B 2 respectively, preventing pin A 1 from moving to the lower end of the groove under strong winds during the skylight's opening and closing process, thus preventing the skylight from closing properly. The transmission rod 8 is the main component 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. The finger piece 9 is connected to the transmission rod 8 via the C rotating shaft 3 and is constrained by the D pin 4. With the coordinated movement of the transmission rod 8 and the transmission mechanism, locking and unlocking actions can be completed. The locking receiver 10 is fixed to the smoke exhaust skylight with fasteners. When the finger piece 9 engages in locking, the locking receiver 10 cooperates with the finger piece 9 to increase the locking force of the skylight. In this invention, the window sash with the supporting finger is located in the middle or slightly off-center support structure of the window sash.

[0014] The self-locking structure of this invention can be used in any structure such as the skylight described above. Specifically, in the case of a double-leaf window, the self-locking structure is exactly the same as described above.

[0015] Example of working principle and process: The working principle of this invention is shown in the figure.

[0016] When the skylight is completely closed, the skylight situation is as follows: Figure 1 At this time, pin 1, driven by the transmission mechanism, moves to the lower end of the central support groove 11. Driven by pin 1, the transmission rod 8 drives the finger 9 to rotate around pin 4 under the constraint of rotating shaft 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.

[0017] 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, pin A1 moves to the upper end of the central support groove 11 under the drive of the transmission mechanism. Driven by pin A1, the transmission rod drives the finger 9 to rotate around pin D4 under the constraint of rotating shaft C3. During the rotation, the finger 9 cooperates with the lock 10 to complete the unlocking action, so that the sunroof can be opened normally.

[0018] 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, remains at the upper end of the central support groove 11. Under the constraint of pin 1, transmission rod 8 also constrains finger 9 connected to transmission rod 8, and finger 9 remains in the "unlocked" state.

[0019] 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.
