Description

Technical Field

[0001] This application relates to the field of roller shutter doors, and in particular to roller shutter door panels. Background Technology

[0002] A roller shutter door consists of multiple articulated door panels linked together, rotating up and down around a central roller within fixed tracks. The door panels are typically connected via either a through-hole connection or a direct metal hook connection. In a through-hole connection, each door panel has a large and a small connector at both ends. The large connector of one panel fits directly onto the small connector of the adjacent panel, allowing the panels to rotate relative to each other and enabling the roller shutter to retract. These connectors are generally made of metal, and over time, they wear out significantly, affecting the lifespan of the roller shutter door panels. Utility Model Content

[0025] The roller shutter door panel provided in this application includes at least two first door panel bodies. One end of each first door panel body has a first engaging portion, and the other end has a second engaging portion. Two adjacent first door panel bodies are connected in series by engaging the first engaging portion and the second engaging portion, allowing relative rotation between them. At least one wear-resistant member is provided between the first engaging portion of one of the two adjacent first door panel bodies and the second engaging portion of the other. In this application's technical solution, by providing a wear-resistant member between the first engaging portion of one of the two adjacent first door panel bodies and the second engaging portion of the other, direct contact between the first engaging portion and the second engaging portion is avoided, thereby reducing wear between the first door panel bodies and improving the service life of the roller shutter door panel.

[0026] Please refer to the following: Figure 1-4 , Figure 1 This is a schematic diagram of the structure of a roller shutter door panel provided in some embodiments of this application. Figure 2 This is a schematic diagram of the structure of the first gate body provided in some embodiments of this application. Figure 3This is a schematic diagram of the connection structure between the first door panel body and the second door panel body provided in some embodiments of this application.

[0027] The roller shutter door panel 100 provided in this embodiment includes, but is not limited to, at least two first door panel bodies 110 and at least one wear-resistant component 120. One end of each first door panel body 110 has a first engaging portion 111. The other end of each first door panel body 110 has a second engaging portion 112. Two adjacent first door panel bodies 110 are connected in series by engaging the first engaging portion 111 and the second engaging portion 112. The two adjacent first door panel bodies 110 can rotate relative to each other. The wear-resistant component is disposed between the first engaging portion 111 of one of the two adjacent first door panel bodies 110 and the second engaging portion 112 of the other. By providing the wear-resistant component 120, the wear resistance of the roller shutter door panel can be significantly improved. Since the door panel bodies frequently come into contact and rub against each other during use, the wear-resistant component 120 can effectively reduce the wear caused by this friction, thereby extending the service life of the roller shutter door.

[0028] Furthermore, the first snap-fit ​​portion 111, the wear-resistant part 120, and the second snap-fit ​​portion 112 are all tubular structures. The compactness and uniform weight distribution of the tubular structure can prevent the roller shutter door from operating unevenly due to excessive local weight, thereby improving the operational stability and reliability of the roller shutter door. The wear-resistant part 120 is sleeved on the second snap-fit ​​portion 1112, and the first snap-fit ​​portion 111 is sleeved on the wear-resistant part 120. The sleeved connection makes the wear-resistant part 120 easy to install and disassemble, allowing users to quickly replace worn parts when needed, thus improving maintenance efficiency. During the manufacturing process, if the length of this tubular structure is too long, deformation and bending problems will inevitably occur. Therefore, in this embodiment, the wear-resistant part 120 is preferably set as a multi-segment tubular structure. Shorter tubular structures are easier to maintain processing accuracy and reduce processing errors.

[0029] Furthermore, both the first snap-fit ​​portion 111 and the wear-resistant component 120 are axially open tubular structures, making the installation and disassembly of the wear-resistant component 120 and the first snap-fit ​​portion 111 more convenient. The first door panel body 110 is provided with a plate 113 connected to the outer wall of the second snap-fit ​​portion 112. The plate 113 passes through the axial openings of the wear-resistant component 120 and the first snap-fit ​​portion 111 to limit the relative rotation angle of two adjacent first door panel bodies 110.

[0030] Furthermore, in this embodiment, the second snap-fit ​​portion 112 is preferably an axially open tubular structure. This allows the second snap-fit ​​portion 112 to be easily fitted onto the drive shaft, and the axially open tubular structure can be manufactured using simple cutting or stamping processes, which is less difficult to process and lower in production cost compared to a closed tubular structure. It is understood that in some other embodiments, the second snap-fit ​​portion 112 may also be a closed tubular structure.

[0031] In a roller shutter door, the drive shaft is a key component for transmitting power and controlling the movement of the roller shutter door slats 100. It ensures the efficient and stable operation of the roller shutter door. In this embodiment, the second engaging portion 112 can be interference-fitted with the drive shaft inserted within it. This further enhances the stability and structural strength of the connection between the drive shaft and the roller shutter door slats 100, reduces wear during relative movement between the drive shaft and the second engaging portion 112, improves operational accuracy, and extends the service life of the roller shutter door slats 100.

[0032] Furthermore, the wear-resistant component 120 provided in this embodiment is selected as an open-type bushing, which allows the wear-resistant component 120 to protect the first latching portion 111 and the second latching portion 112 while also absorbing the vibration and impact force generated by the roller shutter slat 100 during operation. Since plastic material has good wear resistance, it can effectively reduce wear caused by frequent friction and extend the service life of the wear-resistant component 120. Therefore, in this embodiment, the wear-resistant component 120 is preferably made of plastic. At the same time, plastic material has a certain degree of elasticity and shock absorption properties, which can effectively absorb the impact force and vibration generated by the roller shutter slat 100 during operation and reduce noise.

[0033] Furthermore, the first door panel body 110 has a first wall 114 and a second wall 115 facing away from each other. One end of the first door panel body 110 has a connected mounting groove 116 and a first snap-fit ​​portion 111 formed between the first wall 114 and the second wall 115. The mounting groove 116 is closer to the first wall 114 than the first snap-fit ​​portion 111. The roller shutter door panel 100 also includes at least one first sealing strip 117, with the first sealing strip 130 inserted into the mounting groove 116. In this way, the structural strength, sealing performance, sound insulation effect, and service life of the roller shutter door can be improved.

[0034] Furthermore, the groove wall of the mounting groove 116 has a concave-convex arc-shaped wall surface 1161. The concave-convex arc-shaped wall surface 1161 is interference-fitted with the outer wall of the first sealing strip 130, so that the sealing strip 130 will not loosen or fall off when two adjacent first roller shutter door panels 110 rotate relative to each other, and can maintain a certain sealing effect even when the roller shutter door panels are frequently retracted and unfolded.

[0035] Furthermore, at the other end of the first door panel body 110, a connected receiving groove 118 and a second engaging portion 112 are formed between the first wall 114 and the second wall 115. A portion of the first engaging portion 111 of one of two adjacent first door panel bodies 110 is accommodated in the receiving groove 118 of the other adjacent first door panel body 110. In this way, the receiving groove 118 provides rotational space for the first door panel body 110 to rotate relative to each other during the retraction and unfolding of the roller shutter door 100, while maintaining a tight connection when no relative rotation occurs, ensuring stable operation of the roller shutter door under various working conditions. When no relative rotation occurs between two adjacent first door panel bodies 110, the first sealing strip 130 can fill the gap between the first walls 114 of the two adjacent first door panel bodies 110 to ensure the sealing of the roller shutter door 100 in this state.

[0036] Furthermore, the roller shutter door 100 also includes a second door body 140 and a second sealing strip 150. One end of the second door body 140 is provided with a second engaging portion 112. The second engaging portion 112 of the second door body 140 engages with the first engaging portion 111 of the first door body 111. It can be understood that the second door body is located at the end of the roller shutter door 100. The other end of the second door body 140 is provided with a slot 141. The second sealing strip 150 engages with the slot 141. The second sealing strip 150 can be sealed to the external structure. For example, when the roller shutter door 100 of this embodiment is installed on a door frame, the second sealing strip 150 and the door frame are sealed together to enhance the sealing performance between the roller shutter door 100 and the external structure (door frame), further improving the overall insulation, dustproof, and waterproof performance of the device.

[0037] The roller shutter door panel 100 provided in this application includes at least two first door panel bodies 110. One end of the first door panel body 110 is provided with a first latching portion 111, and the other end of the first door panel body 110 is provided with a second latching portion 112. Two adjacent first door panel bodies 110 are connected in series by latching the first latching portion 111 and the second latching portion 112, and the two adjacent first door panel bodies 110 can rotate relative to each other. At least one wear-resistant member 120 is disposed between the first latching portion 111 of one of the two first door panel bodies 110 and the second latching portion 112 of the other of the two adjacent door panel bodies 110. In the technical solution of this application, a wear-resistant part 120 is provided between the first latching part 111 of one of the two adjacent first door panel bodies 110 and the second latching part 112 of the other two adjacent first door panel bodies 110 to avoid direct contact between the first latching part 111 and the second latching part 112, thereby reducing wear between the first door panel bodies 110 and improving the service life of the roller shutter door panel 100.

[0038] The above description is only a part of the embodiments of this application and does not limit the scope of protection of this application. Any equivalent device or equivalent process transformation made based on the content of this application specification and drawings, or direct or indirect application in other related technical fields, are similarly included in the patent protection scope of this application.
