DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] The utility model provides Figure 1-4 A safety mechanism shown includes a mounting plate 100 and a motor 200. The motor 200 is movably arranged on the mounting plate 100. A support structure 300 is arranged between the mounting plate 100 and the motor 200. The support structure 300 includes a first support plate 301, a second support plate 302 and a positioning member. The first support plate 301 is movably arranged below the motor 200. The first support plate 301 is used to limit the position of the motor 200 by squeezing the motor 200. The second support plate 302 is fixedly arranged on the mounting plate 100. The second support plate 302 is movably connected to the first support plate 301. The positioning member is arranged between the first support plate 301 and the second support plate 302. The positioning member is used to limit the position of the first support plate 301 on the second support plate 302. The first support plate 301 is L-shaped, and the end face of the first support plate 301 facing the second support plate 302 is connected to the interior of the first support plate 301.

[0024] Specific reference Figure 1 and Figure 2 The L-shaped setting of the first support plate 301 is convenient for squeezing the end face of the motor 200 away from the mounting plate 100, thereby facilitating the fixation of the end face of the motor 200 away from the mounting plate 100. One end of the motor 200 is relatively fixed to the mounting plate 100. Therefore, when the first support plate 301 squeezes the other end of the motor 200, both ends of the motor 200 are fixed, avoiding the unsafe hidden dangers of fixing a single end of the motor 200, effectively improving the stability and safety of the installation and use of the motor 200. At the same time, the opposite ends of the first support plate 301 and the second support plate 302 are movably interlaced, prompting the first support plate 301 to move along the second support plate 302, so that the overall length of the first support plate 301 and the second support plate 302 can be flexibly adjusted, and then the motor 200 can be adjusted according to its size. The first support plate 301 and the second support plate 302 can be adjusted in time after the position is adjusted to ensure the stability of the support for the motor 200, thereby enhancing the effectiveness of the use of the first support plate 301 and the second support plate 302. The mounting plate 100 is fixed to the wall, and a transmission wheel and a transmission belt for driving the rolling door are provided between the motor 200 and the mounting plate 100. The motor 200 is used to drive the rotation of the transmission wheel so that the rolling door can be automatically retracted and unreeled. Since the transmission structure of the rolling door is an existing mature technology, it will not be elaborated in detail in this embodiment.

[0025] The positioning member includes a positioning rod 303 and a positioning slot 304. The positioning slot 304 is opened on the side of the second support plate 302. The positioning rod 303 and the positioning slot 304 are movably arranged. The positioning rod 303 is movably arranged on the first support plate 301. A spring 305 is movably arranged between the positioning rod 303 and the first support plate 301. The spring 305 is used to support the position of the positioning rod 303.

[0026] Specific reference Figure 1 and Figure 2 , the spring 305 is sleeved on the positioning rod 303, one end of the positioning rod 303 extends to the inside of the first support plate 301, and the other end of the positioning rod 303 passes through the outer wall of the first support plate 301 and extends to the outside. The positioning rod 303 is set in a T shape, which is convenient for the operator to take and use. One end of the spring 305 is fixed to the positioning rod 303, and the other end of the spring 305 is fixed to the inner wall of the first support plate 301. The positioning rod 303 uses the elastic support of the spring 305 to flexibly intersperse with the positioning groove 304. The shape of the positioning groove 304 is as shown Figure 4 As shown, the positioning groove 304 is composed of a plurality of circular grooves connected to each other, so that when the first support plate 301 moves along the second support plate 302 with the positioning rod 303, the positioning rod 303 can limit the position of the first support plate 301 by interlacing with the positioning groove 304 according to different moving positions, providing effective support for the positioning of the first support plate 301, and also supporting the first support plate 301 at different positions along the second support plate 302, effectively improving the effectiveness and flexibility of the use of the first support plate 301, thereby also ensuring the applicability of the first support plate 301.

[0027] A stabilizing structure 400 is provided on the first support plate 301. The stabilizing structure 400 includes a stabilizing plate 401 and a telescopic rod 403. The stabilizing plate 401 is movably provided at the top of the telescopic rod 403. The telescopic rod 403 is fixedly provided at the top of the first support plate 301. A strip groove is provided at the top of the stabilizing plate 401. A plurality of balls 402 are movably provided in the strip groove.

[0028] Specific reference Figure 1 and Figure 3The stabilizing plate 401 is arranged in an arc shape, which can better fit the outer wall of the motor 200, and provides stable support for the motor 200, so that the spatial distance between the motor 200 and the first support plate 301 is structurally supported, thereby enhancing the stability of the installation position of the motor 200. At the same time, a plurality of balls 402 are installed on the stabilizing plate 401, so that when the stabilizing plate 401 moves with the first support plate 301, the direct friction with the outer wall of the motor 200 is reduced, thereby ensuring the safety of the motor 200. The telescopic rod 403 is a threaded telescopic rod. The telescopic rod 403 consists of two rod bodies connected by threads. By rotating the telescopic rod 403, the height of the stabilizing plate 401 from the first support plate 301 can be adjusted, so that it can better adapt to motors 200 of different diameters and heights, thereby ensuring effective support for the motor 200. With the extrusion of the other end of the motor 200 by the first support plate 301, the stability of the installation position of the motor 200 is effectively improved, and the flexible and adjustable position also improves the diversity of adapting to different motor 200 supports.

[0029] The utility model also provides a rolling shutter door, comprising the above-mentioned safety mechanism.

[0030] 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 replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
