Description

Technical Field

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

[0002] The curtain surface of the fireproof rolling door reaches the lifting and lowering of the rolling door through a transmission device and a control system. It plays the role of fire prevention and fire separation. The product has a flat and beautiful appearance, novel shape, and the characteristic of strong rigidity. The fireproof rolling door is widely used in the fireproof partition areas of industrial and civil buildings, can effectively prevent the spread of fire, and ensure the safety of life and property. It is an indispensable fire prevention facility in modern buildings. It is a movable fire separation, generally made of metal plates such as steel plates, and is composed by means of snap rings or hinges. Usually, it is rolled up in the rotating shaft box at the upper opening of the door and window, and when a fire breaks out, it is put down and unfolded to prevent the fire from spreading from the door and window openings.

[0003] At present, when the fireproof rolling doors on the market are in use, they need to be installed in a suitable position for use. In actual use, when the fireproof rolling door is installed, bolts are required to fix the positions of the shell and the guide rail in the fireproof rolling door. And in most cases, when the fireproof rolling door is in use, the internal fireproof curtain cloth is in a retracted state for a long time, resulting in the pallet at the bottom of the fireproof curtain cloth being in a static state for a long time. As a result, the pallet at the bottom of the fireproof curtain cloth is prone to problems such as rust. And the external guide rail of the fireproof curtain cloth is mostly an integral structure, making it difficult to replace and repair the subsequent pallet, which in turn affects the subsequent use state. At the same time, although the traditional fireproof rolling door can play a certain role in fire prevention and isolation during a fire, it has a slow response speed and poor durability. Summary of the Invention

[0004] The purpose of the utility model is to provide a novel fireproof rolling door system to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A novel fireproof rolling door system includes a shell and a fireproof motor fixedly connected inside the shell. A roller is rotatably connected inside the shell. A first guide rail is fixedly connected to the bottom end of the shell. An installation groove is formed on the outer wall of the first guide rail. A second guide rail is slidably connected inside the installation groove. A groove is formed inside the second guide rail. A disc is arranged inside the groove. A sliding groove is formed on the outer wall of the disc. A sliding rod is slidably connected inside the sliding groove. One end of the sliding rod is fixedly connected to a positioning rod. One end of the positioning rod is slidably connected to a fixing rod. The end of the fixing rod away from the positioning rod is fixedly connected to the inside of the groove.

[0007] Furthermore, a positioning groove is provided inside the installation groove. One end of the positioning rod away from the fixed rod penetrates into the installation groove, and the positioning rod is slidably connected to the second guide rail. One end of the positioning rod is slidably connected to the positioning groove. The addition of the fixed rod restricts the movement track of the positioning rod.

[0008] Furthermore, a spring is fixedly connected between the outer wall of the disc and the groove. A rotating rod is fixedly connected to the side of the outer wall of the disc away from the sliding groove. The addition of the disc enables the rotating rod to drive the spring to move.

[0009] Furthermore, one end of the rotating rod penetrates through the outer wall of the second guide rail and the rotating rod is rotatably connected to the second guide rail. A connection hole is provided on the outer wall of the first guide rail. The addition of the connection hole enables the bolt to fix the position of the first guide rail.

[0010] Furthermore, a fire control box is fixedly connected to the outer wall of the first guide rail. A wire pipe is fixedly connected to the bottom end of the fire control box. A button box is fixedly connected to the bottom end of the wire pipe. The addition of the sliding groove enables the disc to drive the sliding rod to move.

[0011] Furthermore, a fireproof curtain cloth is fixedly connected to the outer wall of the roller. A support plate is provided between the first guide rail and the second guide rail.

In the present utility model, when installing the fireproof rolling shutter door, bolts are required to fix the positions of the housing and the guide rail in the fireproof rolling shutter door. However, when most fireproof rolling shutter doors are in use, the fireproof curtain cloth inside is in a retracted state for a long time, resulting in the support plate at the bottom of the fireproof curtain cloth being in a static state for a long time, and thus the support plate at the bottom of the fireproof curtain cloth is vulnerable to problems such as rust. The outer guide rail of the fireproof curtain cloth is a split structure, which facilitates the subsequent replacement and maintenance of the support plate, and thus does not affect the subsequent use state.

[0014] 2. The novel fireproof rolling shutter door system of the present utility model can improve the response speed of the fireproof rolling shutter door. By setting a fire control box on one side of the first guide rail, a wire pipe at the bottom end of the fire control box, a button box at the bottom end of the wire pipe, and a fireproof motor and a fireproof curtain cloth inside the housing, the subsequent roller can store the fireproof curtain cloth. In the present utility model, the fire control box can monitor the surrounding status in real time. When a fire source occurs around, the fire control box can directly start the fireproof motor, so that the fireproof rolling shutter door system has a faster response speed, higher fireproof performance and better durability. At the same time, the maintenance process is simplified, and the use safety and economy are improved. Description of the Drawings

[0023] Please refer to Figure 1 ,Figure 2 , Figure 3 , Figure 4 and Figure 5 , the present utility model provides a new type of fireproof rolling shutter door system, and the technical solution is as follows:

[0024] A new type of fireproof rolling shutter door system includes a housing 1 and a fireproof motor 2 fixedly connected inside the housing 1. A roller 3 is rotatably connected inside the housing 1. A first guide rail 4 is fixedly connected to the bottom end of the housing 1. An installation groove 5 is formed on the outer wall of the first guide rail 4. A second guide rail 6 is slidably connected inside the installation groove 5. A groove 7 is formed inside the second guide rail 6. A disc 8 is arranged inside the groove 7. A chute 9 is formed on the outer wall of the disc 8. A slide bar 10 is slidably connected inside the chute 9. One end of the slide bar 10 is fixedly connected to a positioning rod 11. One end of the positioning rod 11 is slidably connected to a fixed rod 12. The end of the fixed rod 12 away from the positioning rod 11 is fixedly connected to the inside of the groove 7.

[0025] In a preferred embodiment, a positioning groove 13 is formed inside the installation groove 5. The end of the positioning rod 11 away from the fixed rod 12 penetrates inside the installation groove 5 and the positioning rod 11 is slidably connected to the second guide rail 6. One end of the positioning rod 11 is slidably connected to the positioning groove 13. When the positioning rod 11 moves, the positioning rod 11 will slide on the outer wall of the fixed rod 12, and at the same time, one end of the positioning rod 11 will be separated from the positioning groove 13.
