Description

Technical Field

[0001] This utility model relates to the field of smoke exhaust window technology, specifically to an intelligent fireproof and smoke exhaust safety window. Background Technology

[0002] According to the "Technical Standard for Building Smoke Control and Exhaust Systems," buildings are required to be equipped with corresponding smoke control and exhaust systems. Smoke exhaust systems use natural or mechanical methods to expel fire smoke from rooms, corridors, and other spaces outside the building. Smoke exhaust systems are divided into natural smoke exhaust systems and mechanical smoke exhaust systems.

[0003] The smoke exhaust outlets of natural smoke exhaust systems are located in the smoke storage chambers of the smoke exhaust area, so the smoke exhaust windows are often set at a high position, making them inconvenient to open directly. Currently, smoke exhaust windows mainly use two driving methods: manual and electric. Because electric windows are expensive and have a high failure rate, buildings mainly use manual-driven smoke exhaust windows.

[0004] Manually cranked windows are opened by a hand crank that pushes the window open through a right-angle converter and a transmission rod. However, the opening speed of manually cranked windows is very slow. When a fire occurs, people are busy escaping, and they cannot manually open the smoke exhaust window during the precious escape time, rendering the natural smoke exhaust window useless.

[0005] Therefore, the research objective of this utility model is to design an intelligent fireproof and smoke-venting safety window with a relatively simple structure and a convenient and quick opening mechanism. Utility Model Content

[0006] In view of the technical problems existing in the prior art, the present invention provides an intelligent fireproof and smoke-venting safety window, which can effectively solve the technical problems existing in the prior art.

[0007] The technical solution of this utility model is:

[0008] An intelligent fireproof and smoke-venting safety window, comprising:

[0009] frame;

[0010] A window sash, wherein the window sash is hinged to the frame in a rotatable manner;

[0011] At least one set of electromagnet magnetic latching assemblies, each comprising a first magnetic element and a second magnetic element that are mutually adapted to each other. The first magnetic element is disposed on the side wall of the window sash that is not hinged to the frame, and the second magnetic element is installed on the frame side wall on the same side as the first magnetic element. When the window sash is closed, the electromagnet magnetic latching assembly is energized; when the electromagnet magnetic latching assembly is de-energized, the window sash can be opened.

[0012] At least one pre-tightening elastic element is installed between the window sash and the frame on one side of the electromagnet magnetic latch assembly; when the window sash is closed, the pre-tightening elastic element is compressed; when the electromagnet magnetic latch assembly is de-energized, the pre-tightening elastic element has a tendency to reset and push the window sash to open.

[0013] The hinge point between the window sash and the frame is located on either the left or right side or either the top or bottom side of the window sash, or at the middle position of the window sash in the longitudinal or transverse direction.

[0014] The frame includes an inner frame and an outer frame that are fixedly connected internally and externally. The second magnetic component is embedded in the side wall of the outer frame facing the window sash, and the first magnetic component is embedded in the side wall of the window sash.

[0015] The second magnetic suction component has corresponding pre-tightening elastic components on both sides. The inner frame has an inward recess on the side facing the window sash that is open, which is provided with a mounting hole for installing the pre-tightening elastic component. When the window sash is closed, the pre-tightening elastic component is compressed and installed in the mounting hole.

[0016] The pre-tightening elastic element is a cylindrical spring, and the mounting hole is inclined from the inside out and oriented towards the opening direction of the window sash.

[0017] The outer frame is provided with a positioning damping pad on the side wall that is hinged to the window sash to limit the rotation of the window sash.

[0018] The pre-tightening elastic element is a torsion spring, one end of which is fixed in the mounting hole and the other end is fixed in the side wall of the window sash.

[0019] The window sash is hinged to the frame on both sides by corresponding hinges.

[0020] The electromagnet magnetic latch assembly is connected in parallel to an external electrical control system and an energy storage device. The external electrical control system is connected to an automatic fire alarm system, and a corresponding control button is installed on the wall near the safety window. When the control button is pressed, the electromagnet magnetic latch assembly is de-energized.

[0021] Advantages of this utility model:

[0022] 1) This utility model has a simple structure. It uses the energization of the electromagnet magnetic latch assembly to control the opening, closing and locking of the window sash. By controlling the energization of the electromagnet magnetic latch assembly, the window sash is locked and the pre-tightened elastic element is compressed and fixed. By controlling the de-energization of the electromagnet magnetic latch assembly, the window sash is pushed open by the pre-tightened elastic element in the unlocked state, so as to quickly and conveniently open the smoke exhaust safety window.

[0023] 2) This utility model hinges the window sash horizontally to the frame, and provides corresponding electromagnet magnetic latch assemblies between the upper and lower side walls of the window sash and the frame. Pre-tightening elastic elements are provided on both sides of the upper and lower sets of electromagnet magnetic latch assemblies, with the upper and lower pre-tightening elastic elements facing away from each other and inclined towards the opening direction of the window sash. In use, pressing the control button de-energizes the electromagnet magnetic latch assemblies, and the upper and lower pre-tightening elastic elements, facing away from each other, cooperate to push the window sash away from the frame, achieving rapid opening. Alternatively, in case of fire, the automatic fire alarm system will de-energize the electromagnet magnetic latch assemblies, and the window sash will be limited by the positioning damping pad. The positioning damping pad not only effectively limits the window sash, controls the opening angle to prevent over-opening and facilitates subsequent closing, but also provides effective vibration damping to prevent cracking due to the impact of rapid glass opening.

[0025] In the attached diagram: Frame 1, Inner frame 101, Outer frame 102, Window sash 2, First magnetic clasp 3, Second magnetic clasp 4, Pre-tightening elastic element 5. Detailed Implementation

[0026] To facilitate understanding by those skilled in the art, the structure of this utility model will now be described in further detail with reference to the accompanying drawings:

[0027] Example 1

[0028] refer to Figure 1 An intelligent fireproof and smoke-venting safety window, comprising:

[0029] Framework 1;

[0030] Window sash 2, which is hinged to the frame 1 and can be flipped, with the hinge point located at the middle of the horizontal direction of the window sash 2;

[0031] At least one set of electromagnet magnetic latching assemblies, each comprising a first magnetic element 3 and a second magnetic element 4 that are mutually adapted to each other. The first magnetic element 3 is disposed on the side wall of the window sash 2 that is not hinged to the frame 1, and the second magnetic element 4 is mounted on the side wall of the frame 1 on the same side as the first magnetic element 3. When the window sash 2 is closed, the electromagnet magnetic latching assembly is energized; when the electromagnet magnetic latching assembly is de-energized, the window sash 2 can be opened.

[0032] At least one pre-tightening elastic element 5 is installed between the window sash 2 and the frame 1 on one side of the electromagnet magnetic latch assembly; when the window sash 2 is closed, the pre-tightening elastic element 5 is compressed; when the electromagnet magnetic latch assembly is de-energized, the pre-tightening elastic element 5 has a tendency to reset and push the window sash 2 to open.

[0033] This utility model has a simple structure. It uses the energization of the electromagnet magnetic latch assembly to control the opening, closing and locking of the window sash 2. By controlling the energization of the electromagnet magnetic latch assembly, the window sash 2 is locked, and the pre-tightening elastic element 5 is compressed and fixed. By controlling the de-energization of the electromagnet magnetic latch assembly, the window sash 2 is unlocked and is pushed open by the pre-tightening elastic element 5, so as to quickly and conveniently open the smoke exhaust safety window.

[0034] The frame 1 includes an inner frame 101 and an outer frame 102 that are fixedly connected internally and externally. The second magnetic member 4 is embedded in the side wall of the outer frame 102 facing the window sash 2, and the first magnetic member 3 is embedded in the side wall of the window sash 2.

[0035] The second magnetic suction member 4 is provided with corresponding pre-tightening elastic members 5 on both sides. The inner frame 101 is recessed inward on the side facing the window sash 2 to provide a mounting hole for installing the pre-tightening elastic member 5. When the window sash 2 is closed, the pre-tightening elastic member 5 is compressed and installed in the mounting hole.

[0036] This utility model uses an electromagnet magnetic clasp assembly and a pre-tightening elastic element 5 embedded in the inner and outer frames. This not only limits and securely installs the electromagnet magnetic clasp assembly and the pre-tightening elastic element 5, but also facilitates the tight installation of the window sash 2.

[0037] The pre-tightening elastic element 5 is a cylindrical spring, and the mounting hole is inclined from the inside out towards the opening direction of the window sash 2.

[0038] The outer frame 102 is provided with a positioning damping pad 6 on the side wall that is hinged to the window sash 2 to limit the rotation of the window sash 2.

[0039] The window sash 2 is hinged to the frame 1 on both sides by corresponding hinges.

[0040] This invention hinges the window sash 2 horizontally to the frame 1 at its center. Electromagnetic magnetic latch assemblies are installed between the upper and lower side walls of the window sash 2 and the frame 1. Pre-tightening elastic elements 5 are installed on both sides of the upper and lower sets of electromagnetic magnetic latch assemblies, with the upper and lower pre-tightening elastic elements 5 facing away from each other and inclined towards the opening direction of the window sash 2. When in use, pressing the control button de-energizes the electromagnetic magnetic latch assemblies, and the upper and lower pre-tightening elastic elements 5, facing away from each other, work together to push the window sash 2 away from the frame 1, achieving rapid movement. The window sash 2 is then stopped by the positioning damping pad 6. The positioning damping pad 6 not only works with the hinge to further effectively limit the window sash 2, controlling the opening angle and preventing over-opening, facilitating subsequent closing, but also effectively reduces vibration, preventing cracking due to the impact of rapid glass opening.

[0041] The electromagnet magnetic latch assembly is connected in parallel to an external electrical control system and an energy storage device. The external electrical control system is connected to an automatic fire alarm system, and a corresponding control button is installed on the wall near the safety window. When the control button is pressed, the electromagnet magnetic latch assembly is de-energized.

[0042] This invention connects to an automatic fire alarm system. In the event of a fire, the automatic fire alarm system sounds an alarm and, through an external electrical control system, de-energizes the electromagnet magnetic latch assembly, enabling automatic natural ventilation and smoke extraction. Furthermore, it connects in parallel with the external electrical control system and a power storage device, allowing the power storage device to continue supplying power to the electromagnet magnetic latch assembly during power outages. This effectively prevents the windows from opening automatically when the external electrical control system itself loses power, thus improving practicality.

[0043] Example 2

[0044] The difference from Embodiment 1 is that the pre-tensioning elastic element 5 is a torsion spring, one end of which is fixed in the mounting hole, and the other end is fixed to the side wall of the window sash 2. This not only allows the torsion spring to reset and push the window sash 2, but also limits and controls the window opening angle and provides a buffering effect, while replacing the cylindrical spring and the positioning damping pad 6.

[0045] Example 3

[0046] The difference from Embodiment 1 is that the hinge point between the window sash 2 and the frame 1 is located on either the left or right side or the top or bottom side of the window sash 2, or at the middle position in the longitudinal direction of the window sash 2.

[0047] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
