[0024] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0025] See also Figure 1-4 An energy-saving door and window with a fireproof rolling shutter provided by an embodiment of the utility model includes a rolling shutter box 1 and a rolling shutter 2, and also includes: a rotating shaft 3, which is rotatably arranged in the rolling shutter box 1; a rolling tube 4, which is coaxially connected to the rotating shaft 3, and the rolling shutter 2 can be rolled up on the rolling tube 4; a barrier 5, which is coaxially connected to the rotating shaft 3, and is spaced apart from the end of the rolling tube 4 to form a positioning gap, the two ends of the rolling shutter 2 along the axial direction of the rotating shaft 3 correspond to the positioning gaps at the two ends of the rolling tube 4 respectively, and an anti-trip buckle 6 is provided on the inner side of the rolled-up rolling shutter 2.

[0026] Specifically, the shutter box 1 is made of steel, which is fireproof and burn-resistant; the shutter 2 is made of special fireproof materials, which will undergo chemical changes under high temperature or flame, absorb heat without releasing heat, and reduce the generation of thermal radiation. It can be preferably made of inorganic fiber materials, inorganic fiber composite materials, glass fiber cloth, ceramic fiber cloth or fluorocarbon coated cloth, etc. In addition, the shutter 2 also has weaker light transmittance to achieve the sunshade function. The rotating shaft 3 is horizontally arranged near the center position in the rolling shutter box 1; the axial length of the rolling tube 4 is smaller than the corresponding horizontal length of the rolling shutter 2, and the two ends of the rolling shutter 2 cover the two ends of the rolling tube 4; the rotating shaft 3 drives the rolling tube 4 to rotate to realize the winding and unwinding of the rolling shutter 2; the barrier 5 is preferably a ring plate, and the outer diameter is close to the outer diameter of the rolling tube 4; the end of the rolling tube 4 and the barrier 5 are arranged at intervals, and the area in the interval is a part of the rotating shaft 3, and the above three constitute an "I"-shaped part, and the concave area presented by this part is the positioning gap; the spacing between the end of the rolling tube 4 and the barrier 5 matches the width of the anti-trip buckle 6, that is, the anti-trip buckle 6 can smoothly enter and exit the positioning gap. In actual use of this technical solution, when the rolling tube 4 rotates to roll up the rolling shutter 2, the horizontal sides of the rolling shutter 2 are rolled up corresponding to the positioning gap between the end of the rolling tube 4 and the barrier 5, thereby making the anti-trip buckle 6 embedded in the positioning gap, thereby preventing the rolling shutter 2 from running off during the rolling process.

[0027] Compared with the prior art, the energy-saving door and window with a fireproof roller shutter proposed in the embodiment of the utility model is configured with a roller tube 4 and a barrier member 5 so that a recessed positioning gap is formed in the rotating shaft 3 therebetween, and the axial length of the roller shutter 2 covers the length of the roller tube 4, so that the anti-trip buckle 6 corresponds to the positioning gap, and then when the roller tube 4 rotates to reel in the roller shutter 2, the anti-trip buckle 6 can be embedded in the positioning gap, thereby preventing the roller shutter 2 from deviating during the reeling process, thereby improving the practicability of the device.

[0028] As the preferred technical solution of this embodiment, an anti-slip track 7 is connected to the bottom of the rolling shutter box 1, and the side of the rolling shutter 2 is slidably connected to the anti-slip track 7, and the anti-slip buckle 6 is embedded in the anti-slip track 7. Specifically, the anti-slip track 7 is made of steel, which is fire-proof and burn-resistant; the anti-slip track 7 is arranged on both horizontal sides corresponding to the rolling shutter 2, and a vertical opening is arranged on the side close to the rolling shutter 2. The rolling shutter 2 slides up and down in the opening, and the anti-slip buckle 6 is too large to pass through the opening, thereby preventing the rolling shutter 2 from leaving the working position.

[0029] As the preferred technical scheme of the present embodiment, the inner wall of the opening of the anti-slip track 7 penetrated by the rolling shutter 2 is provided with a thermal expansion strip 8, specifically, the opening of the same anti-slip track 7 is preferably two thermal expansion strips 8, and the two thermal expansion strips 8 are symmetrically arranged on the front and rear sides corresponding to the rolling shutter 2; the thermal expansion strip 8 can preferably be made of rubber material; before the fire occurs, the thermal expansion strip 8 keeps shrinking and does not affect the sliding of the rolling shutter 2 in the opening of the anti-slip track 7; when the fire occurs, the temperature near the rolling shutter 2 rises, and the thermal expansion strip 8 begins to respond, and when the temperature near it exceeds 70°C, the thermal expansion strip 8 violently reacts and expands to close the opening of the anti-slip track 7, effectively filling the surrounding gaps to form a tight fire barrier, which can isolate the spread of flames and smoke and delay the spread of the fire; in addition, during the expansion process of the thermal expansion strip 8, the carbon foam formed has viscosity and will not ash, flow or fall, further enhancing its fireproof effect.

[0030] As the preferred technical solution of this embodiment, the unwinding end of the roller shutter 2 is connected to a counterweight bottom beam 9. Specifically, the counterweight bottom beam 9 is used to make the roller shutter 2 have a downward tendency; the counterweight bottom beam 9 is horizontally arranged, and the length matches the spacing between the two anti-derailment rails 7.

[0031] In another embodiment of the utility model, a temperature-controlled clutch assembly is provided at one end of the rotating shaft 3. Specifically, the temperature-controlled clutch assembly includes a transmission pulley 10 and a temperature-controlled self-detaching base 11. The transmission pulley 10 is connected to the rotating shaft 3 through the temperature-controlled self-detaching base 11. When the ambient temperature exceeds 60°C, the temperature-controlled self-detaching base 11 is disconnected from the rotating shaft 3. The transmission pulley 10 can be connected to the belt of the electromechanical drive mechanism or the hand belt of the manual drive mechanism, and it actively drives the rotating shaft 3 to rotate to realize the active retraction and unwinding of the rolling curtain 2. Under this connection mode, when the transmission pulley 10 is not driven, the rolling curtain 2 remains stationary; when the ambient temperature exceeds 60°C, the temperature-controlled self-detaching base 11 is disconnected from the rotating shaft 3, that is, the transmission pulley 10 no longer actively drives the rotating shaft 3, and the rotating shaft 3 can rotate freely. As a result, the rolling curtain 2 is automatically unfolded under the influence of the counterweight bottom beam 9, that is, the automatic fire protection function is realized. Furthermore, the drive pulley 10 is sleeved on the rotating shaft 3 and is coaxially connected to the temperature-controlled self-detachable base 11. The temperature-controlled self-detachable base 11 is connected to the rotating shaft 3 through a temperature-controlled pin. The temperature-controlled pin is controlled by the smoke temperature sensing device on the outside of the rolling shutter box 1. When a fire is detected, the temperature-controlled pin is controlled to disengage from the rotating shaft 3, so that the temperature-controlled self-detachable base 11 is disconnected from the rotating shaft 3. At this time, the rotating shaft 3 rotates freely, and the rolling shutter 2 can be automatically released and fall.

[0032] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
