[0016] A rolling door comprises a rolling door tail plug.

[0017] Therefore, the present invention adopts the above-mentioned rolling door tail plug and rolling door, and its technical effects are as follows:

[0018] Enhanced stability: Multiple components in the tail plug structure, such as the outer tube, mounting plate, snap ring, pin, bearing and bearing fixing seat, etc., are precisely designed and matched to form a stable whole. This structure enables the tail plug to maintain stable performance when bearing the weight of the rolling door and various forces generated during operation, and is not prone to deformation or loosening.

[0019] Improved strength: Especially when the tail plug structure adopts high-strength components such as rolling bearings, fixed sleeves and sliding sleeves, the load-bearing capacity of the tail plug can be significantly improved, ensuring the stability and safety of the rolling door during long-term use.

[0020] Easy to install: The design of the tail plug structure often takes into account the convenience of installation, such as bolt connection, welding or integrated molding, so that the tail plug can be quickly installed on the corresponding position of the rolling door. At the same time, some tail plugs are also designed with adjustable parts to adapt to rolling doors of different sizes and specifications, further simplifying the installation process. In addition, when assembling the tail plug, the simple structure of the tail plug makes it easier to assemble the tail plug.

[0021] Easy maintenance: The detachable and modular design of the tail plug structure makes it easy to operate when maintenance or replacement of parts is required, reducing maintenance costs and time.

[0022] Adjustability: Some tail plug structures also have adjustable functions, such as changing the telescopic length of the tail plug by adjusting the sliding position of the sleeve to adapt to the requirements of rolling doors of different lengths or installation space.

[0023] Protecting users: Some tail plug structure designs take the safety of users into consideration. For example, by avoiding the need to insert fingers into a small space for adjustment, safety hazards during use are reduced.

[0024] Enhance the safety of rolling door: As an important part of rolling door, the stability and strength of the tail plug are directly related to the safety of rolling door. A well-designed tail plug structure can significantly improve the overall safety of rolling door and prevent rolling door failure or accidents caused by loose or damaged tail plug.
