[0024] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0025] The components of the present invention embodiments described and shown in the accompanying drawings can typically be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

[0026] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] like Figures 1 to 4As shown, this utility model proposes a high-speed safety door for welding room renovation, including a safety door body 1. The safety door body 1 is existing technology and will not be described in detail here. A movable rod 2 is installed at the bottom of the door curtain of the safety door body 1. After the movable rod 2 is fixed, the position of the door curtain is fixed. Slide rails 3 are set on both sides of the movable rod 2. The slide rails 3 are arranged in a "U" shape. The two sets of slide rails 3 are fixedly connected to the bottom of the safety door body 1. The bottom of the two sets of slide rails 3 are fixedly connected to a base plate 31. The positions of the slide rails 3 and the base plate 31 are fixed.

[0030] Furthermore, the aforementioned high-speed safety door includes two sets of limiting components 4, which are respectively disposed on both sides of the moving rod 2. The limiting components 4 are used to limit the movement of the moving rod 2. The limiting components 4 include a synchronization block 41 fixedly connected to one end of the moving rod 2. The synchronization block 41 has a T-shaped structure and slides with the slide rail 3. The synchronization block 41 moves synchronously with the moving rod 2, making the movement of the moving rod 2 smooth. A fixing sleeve 42 is sleeved on the outside of the synchronization block 41. A moving block 43 is fixedly connected to the side of the fixing sleeve 42 away from the moving rod 2. When the moving rod 2 moves, it drives the synchronization block 41, the fixing sleeve 42, and the moving block 43 to move synchronously. A positioning rod 44 is slidably connected in the moving block 43. The positioning rod 44 is fixedly connected between the safety door body 1 and the base plate 31. The position of the positioning rod 44 is fixed, and it limits the movement of the moving rod 2 when it moves, making the movement of the moving rod 2 more stable.

[0031] Furthermore, the aforementioned high-speed safety door also includes a locking mechanism 5 installed in the slide rail 3, which is used to lock the moving rod 2. The locking mechanism 5 includes a pressing block 51 slidably connected to the moving block 43. A rubber pad is provided on the side of the pressing block 51 near the positioning rod 44. When the pressing block 51 presses the positioning rod 44, it fixes the moving block 43 to the positioning rod 44 at a fixed height. Two sets of connecting rods 52 are fixedly connected to the side of the pressing block 51 away from the moving rod 2. The ends of the multiple sets of connecting rods 52 away from the pressing block 51 are all fixedly connected to a push plate 53. The push plate 53 moves synchronously with the pressing block 51 through the connecting rods 52. A fixing frame 54 is fixedly connected to the side of the moving block 43 away from the fixing sleeve 42. The fixing frame 54 is U-shaped. Both sets of connecting rods 52 pass through the fixing frame 54 and slide with it, so that the movement of the connecting rods 52 and the push plate 53 is smooth. A spring 55, sleeved on the outer ring of the connecting rod 52, is provided between the push plate 53 and the fixed frame 54. This spring releases the elastic force, causing the pressing block 51 to move away from the positioning rod 44, thus facilitating the movement of the moving rod 2. A moving plate 56 is provided on the side of the push plate 53 away from the moving rod 2. The moving plate 56 is slidably connected to the slide rail 3. Multiple sets of limiting rods 57 are fixedly connected to the side of the moving plate 56 away from the moving rod 2. One end of the limiting rod 57 passes through the slide rail 3 and is slidably connected to a limiting sleeve 58. The limiting sleeve 58 is installed on the side of the slide rail 3 away from the moving rod 2. The limiting action of the limiting rods 57 and the limiting sleeve 58 ensures smooth movement of the moving plate 56. Multiple sets of push rod motors 59 are also installed on the side of the slide rail 3 away from the moving rod 2. The output end of the push rod motor 59 passes through the slide rail 3 and is fixedly connected to the moving plate 56. The push rod motor 59 is used to drive the moving plate 56 to move after starting.

[0032] In this embodiment, when the door curtain moves up and down, it drives the moving rod 2 to move synchronously. The moving rod 2 moves smoothly under the limiting action of the synchronizing block 41 and the positioning rod 44, while simultaneously driving the moving block 43 to slide on the positioning rod 44. When the moving rod 2 moves to the designated position, making the opening space below the safety door body 1 sufficient, multiple sets of push rod motors 59 are activated, and the push rod motors 59 drive the moving plate 56 to move. The moving plate 56 slides smoothly in the slide rail 3 under the limiting action of the limiting rod 57 and the limiting sleeve 58, and pushes the push plate 53 closer to the moving rod 2. At this time, when the push plate 53 moves, it drives the pressing block 51 to approach and press the positioning rod 44 through the connecting rod 52. Since the rubber pad on the side of the pressing block 51 close to the positioning rod 44 increases the friction, it prevents the moving block 43 from sliding on the positioning rod 44. At this time, the height of the moving rod 2 is fixed, effectively preventing safety accidents caused by the door curtain falling.

[0033] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
