However, the current zip type rolling shutter door mainly improves the anti-pulling and wind resistance of the rolling shutter door through the tightness of the zipper, and the sealing between the rolling shutter door body and the lateral guide rail mainly depends on the tightness. The lateral guide rails on both sides cannot be horizontally tensioned and reset in the case of deformation of the rolling shutter door body, resulting in single functionality and limited anti-pulling and sealing. SUMMARY

[0003] The technical problem to be solved by the present application is that the current zip type rolling shutter door mainly improves the anti-pulling and wind resistance of the rolling shutter door through the tightness of the zipper, and the lateral guide rails on both sides cannot be horizontally tensioned and reset in the case of deformation of the rolling shutter door body, resulting in single functionality and limited anti-pulling and sealing.

[0004] The technical scheme adopted by the present application to solve the technical problem is a zip door with reinforced lateral locking device, comprising an aluminum alloy profile straight rail, a flexible rolling shutter door body, a zip door compartment and a tubular motor. The zip door compartment is fixedly installed on the upper end of the profile straight rail. The tubular motor is fixedly assembled with the zip door compartment by being inserted into the interior of the zip door compartment from one side. The profile straight rail is movably assembled with a longitudinal side transmission chain controlled by the tubular motor. The lower end of the flexible rolling shutter door body is fixedly assembled with an aluminum alloy bottom beam. A plurality of lateral iron adsorption springs are sewn on the two side walls of the flexible rolling shutter door body. A strip-shaped electromagnet matched with the lateral iron adsorption springs is installed on the inner side of the profile straight rail. An electric control type tensioning device is installed on the inner side of the profile straight rail and located on the inner side of the longitudinal side transmission chain.

[0005] The two sides of the flexible rolling shutter door body are sewn with lateral edge covering sleeves at the installation end of the lateral iron adsorption springs. The lateral iron adsorption spring comprises an assembly section fixed on the inner side of the lateral edge covering sleeve and a lateral bending section located on one side of the assembly section.

[0006] The electric control type tensioning device comprises a turnover extrusion arm installed on the inner side of the profile straight rail through a lateral assembly shaft, an extrusion gear movably installed on the top end of the side wall of the turnover extrusion arm, and a lateral hydraulic support rod for controlling the turnover extrusion arm.

[0007] The inner side of the profile rail is elastically fitted with a flip guide plate for installing a bar electromagnet at the opening position.

[0008] The outer wall of the aluminum alloy bottom beam is provided with a lateral flip-up storage groove and a lateral extrusion and expansion groove connected to the lateral flip-up storage groove.

[0009] The lateral flip-up storage slot is equipped with a lateral flip-up closing cover and an arc-shaped toothed shell fixed to the inner arc-shaped surface of the lateral flip-up closing cover via an inner mounting shaft.

[0010] The lateral extrusion telescopic groove is elastically fitted with a lateral extrusion telescopic block for controlling the lateral flipping and closing of the cover.

[0011] The lateral compression telescopic block includes an outer telescopic block that is slidably inserted into the lateral compression telescopic groove, an inner compression spring installed between the inner wall of the lateral compression telescopic groove and the inner side of the outer telescopic block, and an inner drive tooth groove opened on the side wall of the outer telescopic block. The outer telescopic block engages with the arc-shaped toothed shell through the inner drive tooth groove.

[0012] The aluminum alloy bottom beam is connected to the longitudinal transmission chain via two side mounting shafts.

[0013] The inner side of the profile straight rail and the outer side of the flip guide plate are elastically connected by a bent spring sheet, and the flip guide plate is movably equipped with a side-positioned limiting guide wheel.

[0014] The beneficial effects of this invention are:

[0015] (1) A silent zipper door with a reinforced lateral locking device of the present invention is provided by installing a strip electromagnet on the inner side of the profile straight rail, which cooperates with the lateral iron adsorption spring. The strip electromagnet can be used to pull laterally when the flexible roller shutter door body is deformed, so as to prevent the flexible roller shutter door body from slipping off and improve the deformation resistance and reset ability of the flexible roller shutter door body.

[0016] (2) An electrically controlled tensioning device is installed on the inner side of the profile straight rail, located inside the longitudinal transmission chain. The electrically controlled tensioning device can help increase the tension of the longitudinal transmission chain, thereby improving the transmission stability.

[0017] (3) By assembling the lateral iron adsorption springs with the lateral edge banding sleeves sewn on both sides of the flexible roller shutter body, the lateral tensile strength can be improved without affecting the rolling of the flexible roller shutter body.

[0018] (4) The bar electromagnet is assembled by a flipping guide plate that is elastically connected to the profile rail. It can be flipped under a large force, which improves the adhesion and stability between the bar electromagnet and the lateral iron adsorption spring.

[0019] (5) The built-in layout design can improve the durability of the entire mechanism;

[0020] (6) By installing a lateral extrusion block on the outside of the aluminum alloy bottom beam to control the lateral flipping and closing of the cover, the sealing performance at the bottom gap can be improved when fully closed. Attached Figure Description

[0028] Figure 1 , Figure 2 , Figure 3 and Figure 4The illustrated silent sliding door with reinforced lateral locking device comprises an aluminum profile straight rail 1, a flexible roller shutter door body 2, a sliding door compartment 3 and a tubular motor 4. The sliding door compartment 3 is fixedly installed on the upper end of the profile straight rail 1, and the tubular motor 4 is fixedly assembled with the sliding door compartment 3 by being inserted into the inside of the sliding door compartment 3 from one side. The profile straight rail 1 is movably assembled with a longitudinal side transmission chain 5 controlled by the tubular motor 4. The lower end of the flexible roller shutter door body 2 is fixedly assembled with an aluminum alloy bottom beam 6. A plurality of lateral iron adsorption elastic pieces 7 are sewn on the two side walls of the flexible roller shutter door body 2. A strip-shaped electromagnet 8 is installed on the inner side of the profile straight rail 1 and cooperates with the lateral iron adsorption elastic pieces. An electric control type tensioning device is installed on the inner side of the profile straight rail 1 and inside the longitudinal side transmission chain 5.

[0029] The tubular motor 4 and the strip-shaped electromagnet 8 are both prior art. The tubular motor 4 is used to control the flexible roller shutter door body 2 and the longitudinal side transmission chain 5, and control the rolling of the flexible roller shutter door body 2 and the rotation of the longitudinal side transmission chain 5.

[0030] The strip-shaped electromagnet 8 is used to magnetically adsorb and fix the lateral iron adsorption elastic pieces 7.

[0031] In order to cooperate with lateral assembly and change the magnetic attraction position, lateral edge covering sleeves 9 are sewn on both sides of the lateral iron adsorption elastic pieces 7 at the lateral iron adsorption elastic piece installation end. The lateral iron adsorption elastic pieces 7 include an assembly section fixed on the inner side of the lateral edge covering sleeve 9 and a lateral bending section located on one side of the assembly section.

[0032] In order to cooperate with the inside electric control hydraulic adjustment, the electric control type tensioning device includes a turnover extrusion arm 10 installed on the inner side of the profile straight rail 1 through lateral assembly shaft, an extrusion gear 11 movably installed on the top end of the side wall of the turnover extrusion arm 10, and a lateral hydraulic support rod 111 used to control the turnover of the turnover extrusion arm 10.

[0033] A pressure sensor controller can be installed on the connection surface of the extrusion gear 11 and the turnover extrusion arm 10. When the pressure changes, the lateral hydraulic support rod 111 will be automatically controlled to extend, and the extrusion tension will be improved. The lateral hydraulic support rod is prior art. It is used to control the turnover of the turnover extrusion arm 10 to the longitudinal side transmission chain 5.

[0034] In order to cooperate with elastic assembly and facilitate lateral tension reset, a turnover guide plate 12 used to install the strip-shaped electromagnet 8 is elastically assembled on the inner side of the profile straight rail 1 at the opening position.

[0035] When the mute zipper door is in a static state, the strip-shaped electromagnet 8 will automatically start to magnetically attract the lateral ferrous adsorption elastic sheet 7, and then when the lateral ferrous adsorption elastic sheet 7 deforms, it will drive the turnover guide plate 12 to turn outward, and after turning over, the pulling force between the strip-shaped electromagnet 8 and the lateral ferrous adsorption elastic sheet 7 will change from the horizontal direction to the vertical direction, thereby enhancing the anti-loosening performance.

[0036] In order to match the lateral assembly, the lateral turnover storage groove 13 and the lateral extrusion expansion groove 14 connected with the lateral turnover storage groove 13 are arranged on the outer wall of the aluminum alloy bottom beam 6.

[0037] In order to match the external turnover, the lateral turnover closing cover 15 and the arc-shaped tooth shell 16 fixed on the inner arc-shaped surface of the lateral turnover closing cover 15 are movably installed on the inner side of the lateral turnover storage groove 13 through the inner assembly shaft.

[0038] The rubber sealing strip is installed on the outer edge of the lateral turnover closing cover 15 to improve the sealing performance with the contact surface and reduce noise.

[0039] In order to match the automatic control when the aluminum alloy bottom beam 6 reaches the bottom, the lateral extrusion expansion block for controlling the lateral turnover closing cover 15 is elastically assembled in the lateral extrusion expansion groove 14.

[0040] In order to match the inner side extrusion transmission, the lateral extrusion expansion block includes the outer side expansion block 17 slidably inserted into the lateral extrusion expansion groove 14, the inner side extrusion spring 18 installed between the inner wall of the lateral extrusion expansion groove 14 and the inner side surface of the outer side expansion block 17, and the inner side driving tooth groove arranged on the side wall of the outer side expansion block 17, and the outer side expansion block 17 is engaged with the arc-shaped tooth shell 16 through the inner side driving tooth groove.

[0041] When the aluminum alloy bottom beam 6 reaches the bottom, the outer side expansion block 17 extrudes the ground, and then the inner side driving tooth groove drives the arc-shaped tooth shell 16 to rotate, thereby controlling the outward turning of the lateral turnover closing cover 15, and finally the outer side of the lateral turnover closing cover 15 contacts the ground, improving the sealing performance of the bottom and avoiding the impact of the aluminum alloy bottom beam 6 on the ground.

[0042] In order to match the lateral linkage, the aluminum alloy bottom beam 6 is connected with the longitudinal side transmission chain 5 through the two side assembly shafts.

[0043] In order to match the elastic reset and lateral limiting, the inner side surface of the profile straight rail 1 and the outer side of the turnover guide plate 12 are elastically connected through the bending elastic sheet 19, and the side limiting guide wheel 20 is movably assembled in the turnover guide plate 12.
