DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model provides Figure 1-3 The fireproof rolling shutter door shown in the figure is easy to open and close, comprising a door frame 1, a rolling shutter body 2 is installed inside the door frame 1, a mounting frame 3 with a transparent end is fixedly connected to one side of the door frame 1, a control switch 4 for electrically controlling the rolling shutter body 2 is fixedly installed inside the mounting frame 3, and a door panel 5 is rotatably installed at the end of the inner cavity of the mounting frame 3. Since the mounting frame 3 is a transparent shape, the corresponding door panel 5 can be opened when the rolling shutter body 2 is on different sides, and the control switch 4 can be operated, and then the rolling shutter body 2 can be opened or closed at different sides of the rolling shutter body 2 through the same control switch 4. A reset component 6 is provided for driving the door panel 5 to close and reset. The reset component 6 can automatically reset and close the opened door panel 5 to prevent the operator from forgetting to close the door panel 5 after opening the door panel 5. A limit component 7 for limiting the switch of the door panel 5 is provided inside the mounting frame 3. Under the action of the limit component 7, the switch of the door panel 5 can be controlled, even if only one of the two door panels 5 in the inner cavity of the mounting frame 3 can be opened at the same time, and the limit component 7 and the reset component 6 are both at the top of the inner cavity of the mounting frame 3, so that when the door panel 5 is opened, the limit component 7 and the reset component 6 will not affect the operation of the control switch 4.

[0025] Furthermore, the limiting assembly 7 includes a limiting sleeve 71, a limiting rod 72 and a second hinge 75. The end of the limiting sleeve 71 is rotatably connected to the door panel 5 through the second hinge 75, and the end of the limiting rod 72 is rotatably connected to the door panel 5 through the second hinge 75, that is, the opposite ends of the limiting sleeve 71 and the limiting rod 72 are rotatably connected to the two door panels 5 respectively, and the outer end of the limiting rod 72 is slidably engaged with the limiting sleeve 71, and one end of the limiting rod 72 is fixedly connected to the limiting shaft 73. The outer wall of the limiting sleeve 71 is provided with a sliding hole 74, and the outer wall of the limiting shaft 73 is slidably engaged with the inner cavity of the sliding hole 74, such as Figure 3 As shown, when one of the door panels 5 is opened, the outer wall of the limiting shaft 73 at one end of the limiting rod 72 fits with the inner wall of the sliding hole 74. At this time, the distance between the limiting sleeve 71 and the opposite end of the limiting rod 72 cannot continue to increase, that is, after one door panel 5 is opened, the other door panel 5 cannot be opened.

[0026] Furthermore, the reset assembly 6 includes a mounting sleeve 61, a connecting rod 62 and a reset spring 63. The mounting sleeve 61 is arranged at the top of the inner cavity of the mounting frame 3. One end of the outer wall of the connecting rod 62 is slidably sleeved with the mounting sleeve 61, and the inner cavity of the mounting sleeve 61 is slidably sleeved with the two connecting rods 62. The opposite ends of the two connecting rods 62 are rotatably connected to the door panel 5 and the mounting frame 3 respectively through the first hinge 66. The reset spring 63 is slidably sleeved on the outer wall of the connecting rod 62. The inner wall of the mounting frame 3 and the inner side of the door panel 5 are fixedly installed with the connecting rod 62. The connecting rod 62 is rotatably connected to the first hinged member 66, and the end of the inner cavity of the mounting sleeve 61 is fixedly sleeved with a fixing ring 64. One end of the connecting rod 62 passes through the fixing ring 64 and is fixedly connected to the limiting plate 65. The reset spring 63 is located between the limiting plate 65 and the fixing ring 64. That is, the reset spring 63 can give the connecting rod 62 an elastic force to move toward the inside of the mounting sleeve 61 through the limiting plate 65, so that the two connecting rods 62 inside the mounting sleeve 61 have a relative movement force, so that the connecting rod 62 can pull the door panel 5 to close.

[0027] Furthermore, the interior of the mounting frame 3 is symmetrically fixedly connected with a mounting shaft 8, the outer wall of the mounting shaft 8 is rotatably interlaced and sleeved with the door panel 5, one side of the inner wall of the mounting frame 3 is symmetrically fixedly connected with a first sealing baffle 9 corresponding to the door panel 5, and the other side of the inner wall of the mounting frame 3 is symmetrically fixedly connected with a second sealing baffle 10 corresponding to the door panel 5. The first sealing baffle 9 and the second sealing baffle 10 can improve the sealing of the two ends of the mounting frame 3 when the door panel 5 is closed, and the mounting frame 3 and the door panel 5 are both made of high temperature resistant material.

[0028] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
