Description

Technical Field

[0001] The utility model relates to the technical field of rolling shutter doors, in particular to a fireproof rolling shutter door. Background Art

[0002] Fireproof rolling shutter doors can prevent fire, isolate smoke and inhibit the spread of fire.

[0003] Fireproof rolling shutter doors generally include a mounting frame, a motor, a roller body, a guide rail and a curtain door. The motor and the roller body are installed on the mounting frame. The motor drives the roller body to rotate, and the roller body drives the curtain door to be lowered or rolled up along the guide rail.

[0004] There are two starting methods for fireproof rolling shutter doors. One is daily use, when the motor drives the roller to rotate, causing the shutter door to drop. The other is emergency start-up, when a fire occurs, the connection between the motor and the roller is cut off, and the shutter door quickly drops due to its own gravity. During emergency start-up, the motor does not rotate. During recovery, in order to match the stroke of the motor and the shutter door, the shutter door needs to be manually lifted and rolled up first, and then the motor and the roller are connected, which makes recovery time-consuming and labor-intensive. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, the purpose of the utility model is to provide a fireproof rolling shutter door. By setting a plurality of clamping parts and corresponding through grooves, after emergency start-up, the motor controls the pull rope to be lowered, and the clamping part can be manually inserted into the through groove to reset it. There is no need to manually retract the rolling shutter door, saving time and effort.

[0006] The technical solution adopted by the utility model is as follows:

[0007] A fireproof rolling shutter door, comprising a guide rail, a roller, a plurality of pull ropes and a plurality of sliding plates, wherein the plurality of sliding plates are slidably installed in the guide rail at intervals, a fireproof cloth is fixedly connected between two adjacent sliding plates, the roller is driven by a motor, and the roller is used to synchronously wind or put down a plurality of pull ropes, a clamping part is installed at the end of each of the pull ropes, a plurality of through slots are opened on the bottom sliding plate, and each of the clamping parts can be clamped into a corresponding through slot;

[0008] It also includes a control part and a transverse moving part. When the fire shutter door is in a retracted state, the control part can control the transverse moving part to extend into or out of a plurality of through slots. When the transverse moving part extends into the through slots, the plurality of clamping parts are pushed out of the corresponding through slots.

[0009] Working principle: In daily working state, the clamping part is located in the corresponding through groove, and the motor drives the roller to rotate, which can wind or lower the drawstring. When winding the drawstring, the sliding plate is driven up by the clamping part, and multiple fireproof cloths are folded. When lowering the drawstring, due to gravity, the sliding plate follows the clamping part to descend, so that the fireproof cloth is unfolded. When emergency start is required, the control part is used to control the lateral moving part to push out the clamping part. At this time, the lowest sliding plate loses support and automatically descends due to gravity. When recovery is required, the motor drives the roller to lower the drawstring and the clamping part, and the clamping part can be manually inserted into the through groove.

[0013] Beneficial effect: when the second block is located in the through slot, since the second block is connected to the compression spring, the second block is not easy to be separated from the through slot, thereby preventing the second block from being separated from the through slot when the pull rope is pulled.

[0014] As a preferred embodiment of the utility model, the lowermost sliding plate is fixedly connected to a limiting frame on the outer side of each through slot, and when the second block is inserted into the through slot, the first block is vertically slidably installed in the limiting frame.

[0015] Beneficial effect: By setting the limiting frame, the first block is limited so that the second block is not easy to escape from the through slot.

[0016] As a preferred embodiment of the present invention, the sliding plate without a through groove is provided with a plurality of avoidance grooves, and each of the first blocks passes through the corresponding avoidance groove when moving following the pull rope.

[0017] Beneficial effect: By setting the avoidance groove, after emergency start, when resetting, the pull rope and the clamping part descend, and the clamping part may be blocked by the sliding plate above. By setting the avoidance groove, movement interference is avoided.

[0018] As a preferred embodiment of the utility model, the control part includes an elastic rope, a control rope and a third block, the upper end of the elastic rope is fixedly mounted on the mounting frame, the lower end of the elastic rope is fixedly connected to the upper end of the third block, and the lower end of the third block is fixedly connected to one end of the control rope;

[0020] The third block rests on the connecting plate, and the contact surfaces between the third block and the connecting plate are both inclined surfaces. When the third block moves downward, the connecting plate is forced to push the top block to push the second block out of the through slot. The upper end of the top block is provided with an inclined surface inclined from top to bottom toward the second block.

[0021] Beneficial effect: Pull the control rope, the control rope pulls the third block down, and when the third block moves downward, it forces the connecting plate to push the top block, pushing the second block out of the through slot. At this time, the lowest sliding plate drops due to gravity, releases the control rope, and the sliding plate rests on the inclined surface of the top block, so that the top block is separated from the through slot, and the sliding plate continues to drop to unfold the fireproof cloth. Through the above structure, emergency start can be achieved after a single pull of the control rope, and the operation is convenient. BRIEF DESCRIPTION OF THE DRAWINGS

By providing the avoidance grooves 42, motion interference is avoided.

[0032] Among them, see Figure 4As shown, each of the clamping parts 9 includes a first block 91, a compression spring 92 and a second block 93. The first block 91 is fixedly connected to the end of the corresponding pull rope 3, and the first block 91 is located on the outer side of the through slot 41. One end of the compression spring 92 is fixedly connected to the inner side of the first block 91, and the other end of the compression spring 92 is fixedly connected to the second block 93. The second block 93 can be inserted into the through slot 41; the lowermost sliding plate 4 is fixedly connected to the limiting frame 43 on the outer side of each through slot 41.

[0036] Specific use (working) process:

[0037] In the daily working state, the clamping part 9 is located in the corresponding through groove 41, and the motor drives the roller to rotate, so as to wind or put down the drawstring 3. When winding the drawstring 3, the sliding plate 4 is driven to rise by the clamping part 9, and the multiple fireproof cloths 5 are folded. When putting down the drawstring 3, due to gravity, the sliding plate 4 follows the clamping part 9 to fall, so that the fireproof cloth 5 is unfolded.

[0038] Pull the control rope 72, and the control rope 72 pulls the third block 73 down. When the third block 73 moves downward, the connecting plate 81 is forced to push the top block 82, and the second block 93 is pushed out of the through slot 41. At this time, the lowest sliding plate 4 drops due to gravity, and the control rope 72 is released. The sliding plate 4 leans against the inclined surface of the top block 82, so that the top block 82 is separated from the through slot 41, and the sliding plate 4 continues to drop, and the fireproof cloth 5 is unfolded.
