Description

Technical Field

[0001] The utility model relates to the technical field of vertical walls, in particular to a lifting type smoke barrier vertical wall. Background Art

[0002] Smoke barrier, also known as smoke baffle or smoke screen, is a device used to block the spread of smoke, soot or odor. It is usually installed in restaurants, kitchens, factories or other places where air pollution needs to be controlled. The design of smoke barrier is usually made of opaque materials such as stainless steel, fiberglass board or polycarbonate to block the spread of smoke. It can be installed above the kitchen range hood to prevent the oil smoke from entering other areas of the restaurant or the outside air. For factories and workshops, smoke barrier can be installed near the production equipment to block the generated smoke from spreading to other areas. The main function of smoke barrier is to keep the indoor air clean and reduce the impact of smoke, soot or odor on the surrounding environment. It can also improve the comfort of the working environment and the work efficiency of employees. Installing smoke barrier also helps to comply with environmental protection regulations and reduce air pollution. In general, smoke barrier is an effective device to control the spread of smoke, soot and odor, which can improve the quality of working and living environment.

[0003] When the existing lifting vertical wall is in use, most of them use winding rollers and fixed vertical guide rails to retract and extend the vertical wall, but the guide rails need to be always on the outside, and the shape is not good enough. If the guide rails are not used, the vertical wall will be blown by the wind when it is lowered, resulting in a poor smoke shielding effect. Utility Model Content

When the use is over, the motor 22 is started, and the output shaft of the motor 22 drives the winding roller 23 to rotate, and the winding roller 23 will reel the soft vertical wall 24. When the soft vertical wall 24 is reeled, the pull rope 212 is pulled, and the pull rope 212 pulls up the positioning rail 25 through the pull ring 211. The output shaft of the motor 22 is fixedly connected to the winding roller 23, and the winding roller 23 The end away from the motor 22 penetrates the installation box 1 and is rotatably connected. The surface of the winding roller 23 is fixedly connected with a soft vertical wall 24. The material of the soft vertical wall 24 is fireproof and high temperature resistant. When the positioning rail 25 falls to the bottom, the pull rope 212 drives the soft vertical wall 24 to be lowered and tightens the soft vertical wall 24 to prevent the soft vertical wall 24 from swinging back and forth under the influence of some wind, thereby affecting its effect of shielding smoke. The limit plate 210 is fixed to the inner wall of the installation box 1. The top surface of the limiting plate 210 is fitted with the positioning rail 25. When the positioning rail 25 is fully retracted, the tension of the pull rope 212 and the resistance of the installation box 1 cause the positioning rail 25 to gradually fall in the direction of the limiting plate 210. The positioning rail 25 will reset the rotating block 29 through the toggle plate 27. At the same time, the fixing bar 26 will resist the limiting plate 210 to prevent the positioning rail 25 from falling. The positioning rail 25 can be retracted while the soft vertical wall 24 is rolled up, which is convenient and fast. The right side surface of the positioning rail 25 is fixedly connected with a fixing bar 26, the top surface of the positioning rail 25 is fixedly connected with a toggle plate 27, the support rod 28 penetrates the installation box 1 and is fixedly connected, the support rod 28 penetrates and is rotatably connected with a rotating block 29, the push cylinder 21 is started, and the output shaft of the push cylinder 21 gradually moves toward the direction of the rotating block 29, when the output shaft of the push cylinder 21 hits the inclined surface of the rotating block 29, the rotating block 29 will rotate with the support rod 28 as the axis. The end of the soft vertical wall 24 away from the winding roller 23 penetrates the positioning rail 25.

The material of the pull rope 212 has a certain toughness, and the rotating block 29 will gradually resist the toggle plate 27 when rotating, and the toggle plate 27 will drive the positioning rail 25 to rotate when it is driven to rotate to a certain extent, and the positioning rail 25 will fall downward and pass through the through hole 4, and when the positioning rail 25 falls downward, it will pull the pull rope 212 through the pull ring 211, and the end of the pull rope 212 away from the pull ring 211 is fixedly connected to the side of the soft vertical wall 24. The cross section of the rotating block 29 is trapezoidal, and the inclined surface of the rotating block 29 faces the pushing cylinder 21. A transverse groove 3 is provided on the bottom surface of the installation box 1, and through holes 4 are provided at both ends of the transverse groove 3. Since the other end of the pull rope 212 is fixedly connected to the soft vertical wall 24, when the positioning rail 25 falls downward, the pull rope 212 will pull the soft vertical wall 24 downward to unfold the rolled soft vertical wall 24.

When the positioning rail 25 is driven to rotate to a certain extent, it will fall downward and pass through the through hole 4. When the positioning rail 25 falls downward, the pull rope 212 will be pulled by the pull ring 211. Since the other end of the pull rope 212 is fixedly connected to the soft vertical wall 24, when the positioning rail 25 falls downward, the soft vertical wall 24 will be pulled downward by the pull rope 212 to unfold the rolled soft vertical wall 24, and at the same time, the fixing bar 26 will hit the top of the through hole 4 to stop the positioning rail 25 from falling, preventing the positioning rail 25 from being completely When the positioning rail 25 falls to the bottom, the pull rope 212 drives the soft vertical wall 24 to be lowered and tightens the soft vertical wall 24 to prevent the soft vertical wall 24 from swinging back and forth under the influence of some wind, thereby affecting its smoke shielding effect.
