DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0030] See also Figure 1The present application provides a sliding rolling shutter door, including a bracket 10, a door body assembly 20 is provided on one side of the bracket 10, and a rolling shutter assembly 30 and a driving assembly 40 are provided on the top of the other side. The driving assembly 40 is connected to the door body assembly 20, and the driving assembly 40 drives the door body assembly 20 to be raised and lowered and rolled into the rolling shutter assembly 30.

[0031] See also Figures 5 to 8 The door assembly 20 includes two door columns 201 and a door body 202 symmetrically arranged on the bracket 10, wherein the door body 202 is composed of a plurality of door leaves 2021, and door leaf connecting mechanisms are arranged on both sides of the door leaves 2021. The door leaf connecting mechanism includes a main body 2022, and the main body 2022 is hollow. The door leaf 2021 is inserted into the main body 2022 and is detachably connected and fixed to the main body 2022. A first connecting member 2023 is arranged on one side of the main body 2022, and a second connecting member 202 corresponding to the first connecting member 2023 is arranged on the other side. 4. The first connecting member 2023 and the second connecting member 2024 are both integrally formed with the main body 2022. The first connecting member 2023 and the second connecting member 2024 both protrude outward. The first connecting member 2023 and the second connecting member 2024 are both provided with an axis hole 2025. When two adjacent door leaves 2021 are connected, the corresponding two adjacent main bodies 2022 are connected by the connecting shaft 2026 passing through the axis hole 2025 on the first connecting member 2023 and the second connecting member 2024 to realize bidirectional rotation connection, that is, the two adjacent door leaves 2021 can realize bidirectional rotation. Specifically, the number of the first connecting member 2023 and the second connecting member 2024 is one, and the position of the first connecting member 2023 and the position of the second connecting member 2024 are staggered and correspond to each other; or, the number of the first connecting member 2023 and the second connecting member 2024 is multiple, and a gap is left between two adjacent first connecting members 2023 / second connecting members 2024, and the positions of the multiple first connecting members 2023 / second connecting members 2024 respectively correspond to the gaps between the multiple second connecting members 2024 / first connecting members 2023.

[0032] Since the door body of the sliding rolling shutter door needs to rotate in both directions during the process of lifting and rolling into the rolling shutter assembly 30, and the adjacent door leaves in the prior art can only be turned in one direction, it cannot meet the normal use requirements of the sliding rolling shutter door. If it is turned forcibly, it may even cause damage to the door body. Through the solution provided by the present application, the two adjacent door leaves 2021 can be connected in both directions by using the protruding first connecting member 2023 and the second connecting member 2024, thereby meeting the use requirements of the sliding rolling shutter door.

[0033] Specifically, a slot (not shown in the figure) is provided at the bottom of each door leaf 2021, and a sealing strip (not shown in the figure) is removably inserted into the slot, thereby improving the sealing between two adjacent door leaves 2021.

[0034] See also Figures 9 to 11 A slide rail 2011 is provided inside the door column 201, and a roller 2027 is provided outside the connecting shaft 2026. The roller 2027 is arranged inside the slide rail 2011 and can slide along the slide rail 2011, so that the door body 202 can be lifted and lowered along the slide rail 2011. A third connecting member 2028 is provided on the side of each door leaf 2021, and the third connecting member 2028 is detachably connected to the door leaf 2021. The driving assembly 40 includes a driving motor (not shown in the figure) and a circulating chain 401. A directional wheel (not shown in the figure) is provided at the bottom of the door column 201. The circulating chain 401 is connected to the driving motor and the directional wheel to realize cyclic rotation. A chain connecting mechanism is installed on the third connecting member 2028, and the chain connecting mechanism is connected to the circulating chain 401. The driving motor drives the door body 202 to move through the circulating chain 401 and the chain connecting mechanism.

[0035] The chain connecting mechanism includes a connecting body 50 and a protrusion 501. The connecting body 50 is detachably connected to the third connecting member 2028, and the protrusion 501 is fixedly connected to the connecting body 50. For example, an integral molding method can be adopted to improve the connection strength between the protrusion 501 and the connecting body 50. A slot 502 is provided on the outer side of the protrusion 501. The internal structure of the slot 502 is adapted to the structure of a single-section chain in the circulating chain 401. A connecting hole corresponding to the single-section chain is provided on the protrusion 501. The single-section chain in the circulating chain 401 is inserted into the slot 502 and fixed.

[0036] The chain connection mechanism used in the prior art is usually in the shape of a long rod, and is connected to the chain through the head and tail ends. Since this type of chain connection member cannot be bent, the chain is very likely to break when it is pulled by the chain connection member when it is bent, and the service life is relatively low. However, the present application scheme uses a protrusion 501 to connect with the circulating chain 401, shortening the connection length between the chain connection mechanism and the circulating chain 401, and at the same time, the internal structure of the card slot 502 is designed to be compatible with the single-section chain in the circulating chain 401, so that the chain connection mechanism will not pull the circulating chain 401 when it is bent, so that the circulating chain 401 can be bent smoothly, thereby improving the service life of the circulating chain 401.

[0037] See also Fig.10 Both ends of the connector 50 near the protrusion 501 are chamfered. The chamfered design allows the connector 50 to provide more space when turning, thereby avoiding pulling on the circulating chain 401.

[0038] See also Fig.11 The connecting body 50 is provided with a plurality of bolt holes 503 , and the connecting body 50 and the third connecting member 2028 are detachably connected by means of bolts inserted into the bolt holes 503 .

[0039] See also Figure 3 and Figure 4 A plurality of bending bearings 2012 and bending gears 2013 are provided at the top of the door body column 201. The plurality of bending bearings 2012 are distributed in an arc shape and are all located at the bottom of the lower circulating chain in the circulating chain 401, and are used to support the lower circulating chain in the circulating chain 401. The bending gear 2013 is located at the bottom of the upper circulating chain in the circulating chain 401, and is used to support the upper circulating chain in the circulating chain 401.

[0040] See also Figure 2 A plurality of supporting components are provided on the top of the bracket 10, and the supporting components include a supporting frame, on which are provided an upper and lower set of transmission wheels 101, each set of transmission wheels 101 is provided with a conveyor belt 102, and the two sets of transmission wheels 101 are respectively located at the bottom of the upper circulating chain and the bottom of the lower circulating chain in the circulating chain 401, and through the rotation of the conveyor belt 102, the circulating chain 401 is supported without interfering with the movement of the circulating chain 401.

[0041] In the existing sliding rolling shutter door, the circulating chain 401 is not provided with a corresponding supporting device, resulting in the chain being suspended for a long time. During the long-term lifting process, the chain is easily stuck, causing chain wear, thereby affecting the service life. The present application provides multiple bending bearings 2012 and bending gears 2013 at the bending part of the circulating chain 401, and at the same time provides a transmission wheel 101 and a conveyor belt 102 at the straight movement part of the circulating chain 401, which can effectively support and protect the circulating chain 401 and improve the service life of the circulating chain 401.

[0042] See also Fig.12 and Fig.13A buffer assembly is provided on the slide rail 2011, and the buffer assembly includes a buffer body 60, a plurality of pulleys 601 and a boss 602. A groove 603 is provided on one side of the buffer body 60, and a boss 602 is provided on the other side. The boss 602 is located below the door body 202, and the boss 602 is fixedly connected to the buffer body 60. For example, an integrated molding design can be adopted to improve the connection strength between the boss 602 and the buffer body 60. A plurality of pulleys 601 are arranged in the groove 603 and are fixedly connected to the groove. The plurality of pulleys 601 are located in the slide rail 2011 and can slide up and down along the slide rail 2011. An elastic member (not shown in the figure) and a directional wheel (not shown in the figure) are provided on the top of the bracket 10. The elastic member is connected to the buffer body 60 through a connecting belt (not shown in the figure). Preferably, the elastic member is a tension spring, the connecting belt is a belt, and the belt is installed on the directional wheel. When the door body 202 descends, the bottom of the door body 202 presses down the boss 602 and drives the buffer body 60 to slide down along the slide rail 2011. At this time, the tension spring is stretched, and the spring can play a buffering role for the door body 202 when it descends, balance the gravity of the door body 202, and reduce the load of the drive assembly 40; when the door body 202 rises, the buffer body 60 automatically lifts up and returns to its position under the action of the contraction of the tension spring, and automatically stops when the spring returns to a normal telescopic state.
