Description

Technical Field

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

[0002] Rolling shutter doors are made of multi-jointed door panels connected in series. In a fixed slide, the door rotates up and down around the scroll above the door. Rolling shutter doors are commonly used in shops. Like walls, rolling shutter doors play the role of horizontal partitions and are generally installed in places where it is inconvenient to use walls for partitions.

[0003] Existing rolling shutter doors are generally used in shops or stores, mainly for anti-theft purposes. General rolling shutter doors are generally locked by restrictions between slide rails and the rolling shutter doors themselves, lacking corresponding reinforcement elements, so they are easily pried open, causing property losses. In addition, when closing the rolling shutter door, if a person or animal passes through the bottom of the rolling shutter door, the rolling shutter door cannot stop descending in time, hitting the person or animal, which is prone to safety accidents. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a novel safety rolling shutter door.

DETAILED DESCRIPTION

[0020] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0021] like Figure 1-Figure 3 As shown, the embodiment of the utility model provides a new type of safety rolling door, including:

[0022] The wall 1 has two slide rails 2 on it. The upper end surfaces of the two slide rails 2 are fixedly connected with support rods 3. The two support rods 3 are provided with fixed rods. The two support rods 3 are fixedly connected with inclined rods 17. The two inclined rods 17 are respectively fixedly connected to the two fixed rods, which improve the stability of the device. The two fixed rods are rotatably connected with a winding roller 4. The winding roller 4 is provided with a rolling curtain body 5. The rolling curtain body 5 is threaded with multiple bolts. The multiple bolts are threadedly connected to the winding roller 4. The two slide rails 2 are provided with a transmission component. The rolling curtain body 5 is provided with a sensing component. The rolling curtain body 5 is arranged in the two slide rails 2. The two slide rails 2 are fixedly connected with connecting blocks. The two connecting blocks are rotatably connected with limiting wheels 18. The two limiting wheels 18 are arranged on the rolling curtain body 5. The limiting wheels 18 can limit the rolling curtain body 5, thereby improving the stability of the rolling curtain body 5 in the slide rails 2.

[0023] The fixing assembly includes two limit assemblies, the limit assembly includes a limit block 6 fixedly connected to the slide rail 2, the limit block 6 is provided with a card slot 7, the roller shutter body 5 is fixedly connected with a fixed block 8, the fixed block 8 is provided with a sliding cavity 9, the sliding cavity 9 is fixedly connected with a spring frame 10 on the inner wall of one side of the limit block 6, the spring frame 10 is fixedly connected with a sliding plate, the sliding plate is fixedly connected with a card block 11, the card block 11 is wedge-shaped, the card block 11 slides through the fixed block 8 and is matched with the card slot 7, the fixed block 8 is provided with a moving cavity 12, the moving cavity 12 is slidably connected with a moving block, the moving block is made of metal, a pull rod slides through the fixed block 8, the two ends of the pull rod are respectively fixedly connected to the sliding plate and the moving block, and an electromagnet 13 is provided on the inner wall of the moving cavity 12 away from the limit block 6;

[0024] The sensing component includes a plurality of mounting grooves arranged on the roller shutter body 5, and sensors 14 are arranged in each of the plurality of mounting grooves. The sensor 14 is a prior art and will not be described in detail here. The transmission component includes a support plate 15 fixedly connected to the slide rail 2, and a first sprocket is rotatably connected to the support plate 15, and a second sprocket is fixedly connected to the winding roller 4. The first sprocket and the second sprocket are transmitted by a chain 16. A rotating machine is fixedly connected to the support plate 15, and the output end of the rotating machine rotates through the support plate 15 and is fixedly connected to the first sprocket.

[0025] The detailed working process of the utility model is as follows:

[0026] When the user needs to put down the roller shutter body 5, the rotating machine starts working first, and the rotating machine drives the first sprocket to rotate. Under the transmission of the chain 16, the winding roller 4 rotates slowly, and the roller shutter body 5 on the winding roller 4 slides on the slide rail 2. The fixed block 8 on the roller shutter body 5 descends, and the block 11 on the fixed block 8 is squeezed by the side wall of the limit block 6. The block 11 is pushed, and the spring frame 10 in the sliding cavity 9 shrinks, so that the block 11 temporarily shrinks into the sliding cavity 9. When the roller shutter body 5 is completely put down, the block 11 is opposite to the slot 7, and the spring frame 10 is reset, so that the block 11 automatically moves to the slot 7. The shutter body 5 is fixed inside, which increases the stability of the shutter body 5 and makes it difficult for the shutter body 5 to be pried upward. When the user is closing the shutter body 5, the sensor 14 arranged under the shutter body 5 monitors in real time. When a person or animal drills in, the rotating machine stops rotating and the shutter body 5 stops descending, thereby avoiding the occurrence of safety accidents. When the user needs to roll up the shutter body 5, the electromagnet 13 starts working first, so that the moving block slides in the moving cavity 12, and the moving block is adsorbed on the electromagnet 13. The pull rod on the moving block pulls the sliding plate, so that the card block 11 is moved out of the card slot 7, which is convenient for the user to roll up the shutter body 5.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
