Description

Technical Field

[0001] This utility model relates to the field of window closing technology, specifically a dual-temperature-sensing automatic window closing device. Background Technology

[0002] Temperature-sensitive window closers are used in various types of operable fireproof windows. These windows are normally open, but in the event of a fire, the temperature-sensitive window closers can automatically close the window sash.

[0003] Commonly used temperature-sensitive window closers also need to have a certain wind resistance to prevent the window from closing due to wind when it is open. Therefore, temperature-sensitive window closers are equipped with resistance adjustment screws to adjust the resistance when closing the window. However, adjusting the resistance by adjusting the screws can affect the operation of the temperature-sensitive window closer, and may result in the window not being able to close in time during a fire. Utility Model Content

[0004] The purpose of this invention is to provide a dual-temperature-sensing automatic window closer to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dual-temperature-sensing automatic window closer, comprising a square tube frame, the square tube frame being connected to a housing, a spring and a piston block being installed inside the square tube frame and the housing, and a resistance device being provided inside the piston block, using the elastic force of the spring to achieve automatic window closing;

[0006] A flip block is rotatably connected to a piston block via a pin. A first temperature sensing element and an inclined top block are provided between the flip block and the resistance. When the first temperature sensing element breaks, the spring force can directly push the piston block to move. When the first temperature sensing element is intact, it can prevent the spring from pushing the piston block and will not affect the normal opening and closing of the window.

[0007] A rack is connected to a piston block. A gear arm that meshes with the rack is rotatably connected between the square tube frame and the outer shell. After the gear arm is close to the edge of the outer shell, the size of the gear arm and the rack can be appropriately increased to make the window closing force greater.

[0008] The wind-resistant mechanism is rotatably connected to the gear arm, which can prevent the window from closing due to excessive wind force. At the same time, the splitting of the second temperature sensing element of the wind-resistant mechanism will reduce the resistance to closing the window, making the window close more promptly.

[0009] Furthermore, the square tube frame and the outer shell are connected by a first rivet, and the first rivet passes through the gear arm. Tail plugs are fixedly connected to both ends of the square tube frame, and the tail plugs support the springs. The first rivet ensures that the gear arm rotates stably.

[0010] Furthermore, the resistance device includes a slanted pressure block and an adjusting screw screwed to the slanted pressure block. The adjusting screw contacts the outer casing, and turning the adjusting screw can change the resistance to closing the window, which can be flexibly adjusted according to the wind force.

[0011] Furthermore, the piston block is connected to a fixing strip via a first internal hexagonal stud. The fixing strip is fixedly connected to the rack to ensure that the rack moves stably and synchronously with the piston block, making the opening and closing of the window more stable.

[0012] Furthermore, the wind pressure resistance mechanism includes a fixed box, inside which is provided a second temperature sensing element and a resistance block. The resistance block is screwed with a second internal hexagonal screw. The resistance block is slidably connected to a slide bar on the inner wall of the fixed box. The fixed box is screwed with a fixing bolt, and the gear arm is sleeved on the fixing bolt. Tightening the second internal hexagonal screw can also adjust the window closing resistance and improve the window's ability to withstand strong winds.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) When the first temperature sensing element bursts, the inclined top block and the flip block lose their supporting force. The resistance between the flip block and the outer shell decreases, the inclined pressure block can move and the resistance between the adjusting screw and the outer shell decreases. When the second temperature sensing element bursts, the resistance block no longer presses against the glass frame, the sliding resistance of the fixed box decreases, the spring pushes the piston block and the rack to move, the rack drives the gear arm to move, and the window can be closed in time, making the window closing ability more stable.

[0015] (2) Tightening the adjusting screw to contact the outer casing can increase the resistance to closing the window. The resistance block contacts the glass frame, increasing the sliding resistance of the fixing box inside the glass frame. Through the double resistance, the window's wind resistance can be improved, preventing the window from closing accidentally due to wind.

[0016] (3) Gear arms are installed at the widened part of the square tube frame and the outer shell. This structure allows for an increase in the size of the gear arms and racks, ensuring stable transmission of the spring force for closing the window, and enabling better release of the spring force to close the window quickly and stably.

[0024] 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.

[0025] Example:

[0026] Please see Figure 1-6 This utility model provides a technical solution: a dual-temperature sensing automatic window closer, including a square tube frame 1, the square tube frame 1 is connected to a shell 2, a spring 6 and a piston block 7 are installed inside the square tube frame 1 and the shell 2, the piston block 7 is provided with a resistance device, the resistance device changes the sliding resistance of the piston block 7, increases the window closing resistance, and improves the window's wind resistance, and the elastic force of the spring 6 provides a thrust for automatic window closing;

[0027] The flip block 12 is rotatably connected to the piston block 7 via a pin 21. A first temperature sensing element 10 and an inclined top block 9 are provided between the flip block 12 and the resistance. The first temperature sensing element 10 restricts the rotation of the flip block 12, keeping the flip block 12 in contact with the outer shell 2, while restricting the sliding of the inclined top block 9, thereby ensuring that the resistance will not move. Therefore, the piston block 7 will not move due to the thrust of the spring 6, and the window can be opened and closed normally by hand.

[0028] Rack 4, which is connected to piston block 7, and a gear arm 3 that meshes with rack 4 is rotatably connected between square tube frame 1 and outer shell 2. The gear arm 3 drives the window to close by rotating.

[0029] The wind-resistant mechanism is rotatably connected to the gear arm 3. The wind-resistant mechanism can enhance the wind resistance of the window and prevent the window from closing due to strong winds. When the second temperature sensing element 19 of the wind-resistant mechanism breaks, it will reduce the resistance to closing the window and make the automatic window closing more timely.

[0030] In this embodiment, as Figure 1 As shown, the square tube frame 1 and the outer shell 2 are connected by the first rivet 15, and the first rivet 15 passes through the gear arm 3 to realize the rotational installation of the gear arm 3. The two ends of the square tube frame 1 are fixedly connected with tail plugs 14, which are also fixed by the first rivet 15. The left tail plug 14 can support the spring 6 to realize the limited installation of the spring 6.

[0031] In this embodiment, as Figure 1 As shown, the resistance device includes a sloping pressure block 8 and an adjusting screw 11 screwed to the sloping pressure block 8. The adjusting screw 11 contacts the outer shell 2. The inclined surface of the sloping pressure block 8 contacts the inclined surface of the sloping top block 9, which can restrict the movement of the sloping pressure block 8. When the adjusting screw 11 is tightened, it presses against the outer shell 2, increasing the resistance of the piston block 7 to move to the left and increasing the resistance to closing the window. Therefore, the wind resistance of the window can be adjusted.

[0032] In this embodiment, as Figure 1 As shown, the piston block 7 is connected to a fixing strip 5 by a first internal hexagonal stud 13. The fixing strip 5 is fixedly connected to the rack 4 to realize the synchronous movement of the rack 4 and the piston block 7.

[0033] In this embodiment, as Figure 5 As shown, the wind-resistant mechanism includes a fixed box 20. The fixed box 20 is equipped with a second temperature sensing element 19 and a resistance block 18. The resistance block 18 is screwed with a second internal hexagon screw 17. The resistance block 18 is slidably connected to a slide bar 22 on the inner wall of the fixed box 20. The slide bar 22 prevents the resistance block 18 from falling off. The fixed box 20 is slidably connected to the glass frame. The contact between the resistance block 18 and the glass frame can increase the sliding resistance of the fixed box 20, thereby improving the wind resistance of the window.

[0034] In this embodiment, as Figure 1 As shown, the fixing box 20 is screwed with a fixing bolt 16, and the gear arm 3 is sleeved on the fixing bolt 16, so as to realize a stable rotational connection between the gear arm 3 and the fixing box 20.

[0035] Specifically, in use, the square tube frame 1 is installed on the window frame, and the fixing box 20 is slidably connected to the glass frame. If a fire occurs when the window is open, the first and second temperature sensing elements 10 and 2 will burst. After the first temperature sensing element 10 bursts, the flip block 12 and the inclined top block 9 lose their support, and the inclined pressure block 8 also loses its support. The flip block 12 rotates and no longer makes close contact with the outer shell 2, thus losing the resistance to closing the window. The inclined pressure block 8 is in a sliding state and also loses the resistance to closing the window. After the second temperature sensing element bursts, the resistance block 18 is in a sliding state and no longer makes close contact with the glass frame. Therefore, the sliding resistance of the fixing box 20 is reduced. At this time, the spring 6 smoothly pushes the piston block 7 to move. The piston block 7 drives the rack 4 to move through the fixing strip 5. The rack 4 drives the gear arm 3 to rotate. The gear arm 3 can drive the glass frame to rotate, realizing the automatic and rapid closing of the window and timely preventing the fire from spreading into the room.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
