[0023] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.
[0024] Refer to the attached Figure 2 As shown, the rolling shutter door of this embodiment includes a transmission shaft 1 and transmission shaft moving slide rails 10 arranged at both ends of the transmission shaft 1, which are used to enable the transmission shaft 1 to move horizontally when the door panel is folded up or lowered, so as to adapt to the different degrees of rolling up of the door panel on the transmission shaft 1 to adjust the distance change between the transmission shaft 1 and the door post groove 4, so as to keep the door panel and the door post groove 4 from being squeezed against each other, which is scientific and reasonable, so that the operation of the door panel is more stable and smooth, and the noise reduction effect is better.
[0025] For details, please refer to the attached Figure 3 and 4 As shown, the transmission shaft moving slide rail 10 of the rolling door in this embodiment includes: a fixed plate 101 and a sliding block 102.
[0026] The fixing plate 101 is used to be fixed on the inner side of the rolling door frame 2 corresponding to the end of the transmission shaft 1. A first horizontal slide rail 1011 is provided on the upper part of the fixing plate 101. In this embodiment, the first horizontal slide rail 1011 is formed by an upward convex ridge provided on the upper surface of the fixing plate 101, which has a simple structure, is easy to process, and is convenient to assemble.
[0027] One side of the slider 102 is used for fixed connection with the end of the transmission shaft 1, and the other side is provided with a first pulley group 1021 corresponding to the first horizontal slide rail 1011. The first pulley group 1021 includes at least two load-bearing pulleys to drive the slider 102 to slide horizontally along the first horizontal slide rail 1011, thereby driving the transmission shaft 1 to move horizontally. In this embodiment, the first pulley group 1021 includes three load-bearing pulleys, and the load-bearing pulleys are concave wheels corresponding to the upward convex ridges. In this way, the load-bearing pulleys can not only utilize the concave-convex cooperation between their grooves and the upward convex ridges to meet the smooth sliding of the pulleys, but also play the role of fixing the transmission shaft 1, which is convenient for assembly and disassembly.
[0028] In a preferred embodiment, the lower part of the fixed plate 101 is further provided with a second horizontal slide rail 1012. Correspondingly, the slider 102 is provided with a second pulley block 1022 corresponding to the second horizontal slide rail 1012, and the second pulley block 1022 includes at least one limiting pulley. In this embodiment, the second pulley block 1022 includes two limiting pulleys.
[0029] Similarly, the second horizontal slide rail 1012 is formed by a downward convex ridge arranged on the lower surface of the fixed plate 101, and the limiting pulley is a concave wheel corresponding to the downward convex ridge. The limiting pulley has the functions of firstly satisfying the sliding of the slider 102 relative to the fixed plate 101, and secondly limiting the position of the slider 102 to prevent the slider 102 from detaching from the fixed plate 101 and causing an accident.
[0030] In a more preferred embodiment, slider baffles 103 are respectively provided at both ends of the fixed plate 101. In this embodiment, the slider baffles 103 are fixed to the side end surface of the fixed plate 101 by bolts 104, and the upper and lower edges thereof respectively exceed the upper and lower edges of the fixed plate 101. That is, the slider baffles 103 can block the first pulley group 1021 and the second pulley group 1022 to prevent the pulleys from falling off the slide rails.
[0031] When the transmission shaft moving slide rail 10 is used for a rolling door, the end of the transmission shaft 1 is fixedly connected to the slider 102 through the connecting plate 12, so that the transmission shaft 1 slides horizontally on the fixed plate 101 along with the slider 102, which is equivalent to the door panel moving forward and backward.
[0032] When the rolling door is in use, if the door panel is in a fully closed state, there is no door panel wound on the transmission shaft 1. Under the action of the door panel and the door post groove 4, the door panel drives the transmission shaft 1 to rest at the end of the first horizontal slide rail 1011 closest to the door post groove 4. When the rolling door is opened, the door panel begins to be rolled up by the transmission shaft 1. As the door panel becomes thicker and thicker on the transmission shaft 1, the transmission shaft 1 can move away from the door post groove 4 along with the slider 102 until the door panel is fully rolled up. The transmission shaft 1 rests at the farthest end of the first horizontal slide rail 1011 from the door post groove 4. This structure can ensure that the door panel and the door post groove 4 always remain parallel, and no inclined extrusion will occur, which can better protect the door panel from deformation, and the door panel runs smoothly and smoothly with excellent mute effect.
[0033] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Those skilled in the art may make some simple modifications, equivalent changes or modifications using the technical contents disclosed above, which are all within the protection scope of the present invention.
