[0035] Please refer to Figures 1 to 10 , now the fireproof device provided by the embodiments of the present application will be described.

[0036] As shown in Figures 1 to 2 , the fireproof device of the embodiments of the present application comprises a storage box 100, a winding drum mechanism 200, a fireproof blanket 300, and a traction mechanism 400.

[0037] Referring to Figure 1 and Figure 2 , the storage box 100 comprises a box body 110 and a switch door 120; the box body 110 has a storage cavity 111 and an opening 112; the opening 112 communicates with the storage cavity 111; the switch door 120 is rotatably connected with the box body 110, so that the switch door 120 can be folded outwards relative to the box body 110 to open the box body 110; the switch door 120 is used to close the opening 112; the storage cavity 111 is used to accommodate the winding drum mechanism 200, the fireproof blanket 300, and the traction mechanism 400; the switch door 120 is an outward opening door, so as to take the fireproof blanket 300 located in the storage cavity 111;

[0038] Referring to Figure 5 and Figure 6The reel mechanism 200 comprises a rotatable storage reel 210; the fireproof blanket 300 has a fixed end and a traction end respectively at two ends thereof; the fixed end is connected with the storage reel 210, so that the rotatable storage reel 210 can wind the fireproof blanket 300 into a blanket roll to be stored in the storage cavity 111 and protect the fireproof blanket 300 by the box 110 to avoid damage of the fireproof blanket 300 during storage or movement;

[0039] With reference to Figure 2 The traction mechanism 400 is arranged on the traction end; the outer side of the box 110 is provided with a fixing mechanism 130 for detachable connection with the traction mechanism 400; after the switch door 120 is opened outward, the user can grab the traction mechanism 400 in the storage cavity 111 to grab the traction end of the fireproof blanket 300 to unwind the fireproof blanket 300; when the fireproof blanket 300 is unwound to a length sufficient to surround the fire, the user moves the traction rod 410 to the fixing mechanism 130 of the box 110 to connect the fixing mechanism 130 with the traction rod 410, so that the fireproof blanket 300 and the box 110 form a complete fireproof circle to control the fire and prevent the spread of the fire.

[0040] With reference to Figures 1 to 5 To facilitate movement of the fireproof blanket 300, the box 110 is provided with a moving mechanism 140. In this embodiment, the moving mechanism 140 is a plurality of second moving wheels 141 which can contact the ground, and the user can move the entire box 110 by pushing, pulling or other ways to move the entire fireproof device, so that the user can conveniently move the fireproof device to the fire site to quickly expand the fireproof circle to prevent the spread of the fire.

[0041] The fireproof device of the embodiment comprises a storage box 100 for covering the fireproof blanket 300, and the fireproof blanket 300 is stored in the box body 110 in the form of a blanket roll, so as to avoid damage to the fireproof blanket 300 during storage or movement; when a fire occurs, the box body 110 is provided with a moving mechanism 140, and the user can move the entire box body 110 by pushing, pulling or the like, so as to move the fireproof device to the fire site, then open the switch door 120 of the box body 110, and grab the traction mechanism 400 located in the box body 110, so as to drive the fireproof blanket 300 to unroll; when the fireproof blanket 300 is unrolled to surround the fire site, the user fixes the traction rod 410 with the fixing mechanism 130 of the box body 110, so that the fireproof blanket 300 and the box body 110 form a complete fireproof circle to cover the fire and prevent the spread of the fire. Therefore, compared with the existing fireproof blanket 300, the fireproof device of the embodiment can better move the fireproof blanket 300 to the fire site, facilitate the use, and cooperate the fixing mechanism 130 on the box body 110 with the winding mechanism 200 to make the blanket roll stored in the storage cavity 111 unroll to form a complete fireproof circle, so as to facilitate the user to use the fireproof blanket 300, improve the protection efficiency of the fireproof blanket 300, and prevent the spread of the fire in time.

[0042] In some embodiments of the present application, with reference to Figure 1 , Figure 3 , Figure 8 and Figure 9 , the traction mechanism 400 comprises a traction rod 410; the traction rod 410 is arranged on the traction end, the fixing mechanism 130 comprises a clamping seat 131; the clamping seat 131 is provided with clamping arms 132 for clamping the traction rod 410. The traction rod 410 is located on the traction end, so that the user can directly grab the traction rod 410 to drive the fireproof blanket 300 to unroll, so as to more quickly form a fireproof circle that can cover the fire. Moreover, the extension direction of the traction rod 410 is parallel to the width direction of the fireproof blanket 300, and the edge of the fireproof blanket 300 is fixedly connected with the traction rod 410 through adhesive, so as to straighten the fireproof blanket 300 by the traction rod 410, facilitating the winding and unwinding of the fireproof blanket 300. In addition, a traction ring, a traction rope or the like can be used instead of the traction rod 410. The clamping arms 132 are two, so that the clamping seat 131 fixes the traction rod 410, and the fireproof circle is more stable.

[0043] In some embodiments of the present application, with reference to Figure 8 and Figure 9The traction mechanism 400 further comprises a moving frame 420 connected to one end of the traction rod 410, and the moving frame 420 is provided with a plurality of first moving wheels 421. The moving frame 420 is connected to one end of the traction rod 410, and the moving frame 420 is located at the end of the traction rod 410 close to the ground, and the first moving wheels 421 can be in contact with the ground. After the user takes out the traction rod 410 and the fire blanket 300 from the storage box 100, the first moving wheels 421 can be in contact with the ground, so that the weight of the traction mechanism 400 and the traction end of the fire blanket 300 can be supported by the ground, and the user does not need to support the weight of the traction mechanism 400 and the fire blanket 300 with his hands, so that the user can better drag the fire blanket 300 to cover the fire and form a fireproof circle.

[0044] In some embodiments of the present application, with reference to Figure 8 and Figure 9 In order to better release the fire blanket 300, the moving frame 420 is provided with a telescopic rod 422, the traction rod 410 is provided with a sleeve joint hole, the traction rod 410 is sleeved outside the telescopic rod 422 through the sleeve joint hole, and the traction rod 410 is sequentially provided with a first limiting hole 411 and a second limiting hole 412 along the extension direction of the telescopic rod 422; the telescopic rod 422 is provided with a resettable limiting button 423, and the limiting button 423 is used to extend into the first limiting hole 411 or the second limiting hole 412. The resettable limiting button 423 can be popped out by a reset spring, so that the limiting button 423 can extend into the first limiting hole 411 or the second limiting hole 412. When the limiting button 423 extends into the first limiting hole 411, the length of the telescopic rod 422 extending out of the traction rod 410 is shorter; when the limiting button 423 extends into the second limiting hole 412, the length of the telescopic rod 422 extending out of the traction rod 410 is longer. Therefore, when it is needed to put the traction mechanism 400 into the storage box 100, the limiting button 423 is pressed, and the telescopic rod 422 is moved to make the limiting button 423 of the telescopic rod 422 move to the position corresponding to the first limiting hole 411, and the limiting button 423 extends into the first limiting hole 411 under the elastic force of the reset spring to fix the relative position between the telescopic rod 422 and the traction rod 410; when the user opens the switch door 120 and needs to expand the fireproof circle, the limiting button 423 is pressed to make the limiting button 423 retract, the limiting button 423 is separated from the first limiting hole 411, and then the telescopic rod 422 can be moved to extend out of the traction rod 410 until the limiting button 423 extends into the second limiting hole 412 under the elastic force of the reset spring to fix the relative position between the telescopic rod 422 and the traction rod 410, so as to avoid the telescopic rod 422 from continuing to extend or retract.

[0045] Therefore, when the fireproof blanket 300 needs to be stored, the overall length of the traction mechanism 400 can be shortened so as to store the traction mechanism 400 into the box body 110; when the fireproof blanket 300 needs to be unwound, the length of the traction mechanism 400 is increased so that the lower edge of the traction end of the fireproof blanket 300 can be at the same height as the lower edge of the fireproof blanket 300 located in the storage cavity 111 when the first moving wheel 421 of the moving frame 420 is in contact with the ground, so as to unwind and wind the fireproof blanket 300, reduce the wrinkles on the fireproof blanket 300 during unwinding or winding, and avoid the fireproof blanket 300 from being loose and causing the unwinding or winding of the fireproof blanket 300 to be blocked.

[0046] It can be understood that the first moving wheel 421 can be a universal wheel with a brake commonly used in the market; when the traction mechanism 400 is connected with the fixing mechanism 130, the brake on the universal wheel can be stepped on so as to fix the position of the traction mechanism 400 and prevent the traction mechanism 400 from shaking randomly.

[0047] In some embodiments of the present application, with reference to Figure 6 and Figure 7 , the winding drum mechanism 200 further comprises a fixing frame 220 and a driving motor 230; the fixing frame 220 is rotationally connected with the storage winding drum 210, the driving motor 230 is arranged on the fixing frame 220, and the driving end of the driving motor 230 is connected with the storage winding drum 210 so that the driving motor 230 drives the storage winding drum 210 to rotate. The fixing frame 220 comprises two mounting brackets, one of which is provided with a waist-shaped groove, so that the mounting position of the mounting bracket can be adjusted to adjust the distance between the two mounting brackets to adapt to storage winding drums 210 or fireproof blankets 300 of different widths. The mounting bracket is rotationally connected with the storage winding drum 210, which can be rotationally connected by means of a rotating shaft, a bearing or the like, so that the storage winding drum 210 can rotate relative to the box body 110 to wind the fireproof blanket 300. The driving end of the driving motor 230 can be connected with the storage winding drum 210 through a driving ring to drive the storage winding drum 210 to rotate by the driving motor 230.

[0048] It can be understood that the driving motor 230 can control the rotation direction of the driving motor 230 through a forward rotation button and a reverse rotation button; when unwinding is needed, the forward rotation button is pressed to make the driving motor 230 rotate forward, so that the storage winding drum 210 rotates forward to unwind the fireproof blanket 300; when winding is needed, the reverse rotation button is pressed to make the driving motor 230 rotate reversely, so that the storage winding drum 210 rotates reversely to wind the fireproof blanket 300; therefore, the driving motor 230 can be used to automatically unwind and wind the fireproof blanket 300, which can reduce the labor consumption and improve the winding and unwinding efficiency compared with manual winding and unwinding.

[0049] In some embodiments of the present application, with reference toFigure 6 And Figure 7 In order to reduce the volume of the winding drum mechanism 200, the receiving winding drum 210 is arranged outside the driving motor 230, so that the hollow inside the winding drum can accommodate the driving motor 230, thereby better reducing the volume of the entire winding drum mechanism 200 and improving the space utilization.

[0050] In some embodiments of the present application, referring to Figure 1 , Figure 2 And Figure 5 A plurality of second moving wheels 141 are arranged at the bottom of the box body 110, and a telescopic pull rod 150 is arranged at the top of the box body 110. The extension direction of the receiving winding drum 210 of the winding drum mechanism 200 is parallel to the vertical direction, so that the fire blanket 300 can be vertically unwound to form a fireproof ring. The telescopic pull rod 150 can be a telescopic and length-adjustable pull rod commonly used in luggage, and its specific structure is not described here. When the fireproof device needs to be moved, the telescopic pull rod 150 can be extended, and the box body 110 can be inclined, so that the user can drag the box body 110 to move the fireproof device to the fire site or the storage position, facilitating the movement of the fireproof device, so as to take the fire blanket 300.

[0051] In some embodiments of the present application, referring to Figures 1 to 4 A plurality of fixed supports 160 are arranged at the bottom of the box body 110, and the fixed supports 160 are provided with threaded rods 161 extending in the vertical direction, and the bottom of the box body 110 is provided with threaded holes threadedly connected with the threaded rods 161. The fixed support 160 is a common foot cup on the market, and the length of the lower end of the fixed support 160 is adjusted by rotating the fixed support 160, so that the second moving wheel 141 is separated from the ground, thereby supporting the entire box body 110 by the plurality of fixed supports 160, improving the grip of the box body 110, and better fixing the box body 110 on the ground to prevent the box body 110 from collapsing, so as to better surround the fire blanket 300 to form a fireproof ring. When the box body 110 needs to be moved, the length of the lower end of the fixed support 160 can be adjusted by rotating the fixed support 160, so that the lower end of the fixed support 160 gradually approaches the bottom of the box body 110, and then the second moving wheel 141 can be in contact with the ground, thereby facilitating the user to move the box body 110.

[0052] In some embodiments of the present application, referring to Figure 5The second moving wheel 141 is a Foma wheel, which has a fixed platform, when the box 110 is placed vertically, the fixed platform and the fixed support 160 can support the whole box 110, and fix the box 110 in place; when the box 110 is inclined to the wheel of the Foma wheel contacts the ground, the user can move the box 110 by pushing and pulling, to move the whole fireproof device to the destination. In addition, the second moving wheel 141 can also be made of a universal wheel.

[0053] In some embodiments of the present application, referring to Figure 1 In order to facilitate the user to open the switch door 120, the switch door 120 is provided with a handle 121; and in order to allow the user to check the condition of the fire blanket 300 in the box 110, the switch door 120 is provided with a transparent window, specifically, the whole switch door 120 is made of acrylic material, that is, the whole switch door 120 is a transparent window, to facilitate the observation of the state of the fireproof device at any time, and provide emergency safety protection.

[0054] In summary, the fireproof device of the present embodiment includes a storage box 100 covering the fire blanket 300, and the fire blanket 300 is stored in the box 110 in the form of a blanket roll, to avoid damage to the fire blanket 300 during storage or movement; when a fire occurs, the box 110 is provided with a moving mechanism 140, the user can move the whole box 110 by pushing, pulling and other ways, to move the fireproof device to the fire site, then open the switch door 120 of the box 110, and grab the traction mechanism 400 located in the box 110, to drive the fire blanket 300 to unroll; when the fire blanket 300 is unrolled to surround the fire, the user will connect the traction rod 410 with the fixing mechanism 130 of the box 110, so that the fire blanket 300 and the box 110 form a complete fireproof circle to cover the fire and prevent the spread of the fire. Therefore, compared with the existing fire blanket 300, the fireproof device of the present embodiment can better move the fire blanket 300 to the fire site, facilitate the use, and cooperate with the fixing mechanism 130 and the winding mechanism 200 on the box 110, to unroll the blanket roll stored in the storage cavity 111 to form a complete fireproof circle, facilitate the user to use the fire blanket 300, improve the protection efficiency of the fire blanket 300, and prevent the spread of the fire in time.
