Description

Technical Field

[0001] The utility model relates to the technical field of rolling door machines, and more specifically, it relates to a low-noise rolling door machine. Background Art

[0002] A low-noise rolling door machine is a rolling door driving device designed specifically to reduce the noise generated during operation. It effectively reduces the sound when the rolling door opens and closes by adopting advanced driving technologies, special noise control materials, and design improvements. This kind of rolling door machine is widely used in residential areas, hospitals, libraries, and other places with strict requirements for noise control.

[0003] In the existing technologies, firstly, the noise during the operation of some rolling door devices will increase significantly, affecting the comfort of the working environment. There is a lack of coordination among components, and the movement of the rolling door body may be stuck or unbalanced, affecting the use experience and service life of the rolling door. Secondly, the installation and disassembly of some rolling door devices will become more time-consuming and laborious, greatly reducing the convenience of maintenance and replacement. There is a lack of components responsible for ensuring the stability and reliability of the connection, and the absence of them may cause the rolling door to become loose or fall off during use. Finally, for some rolling door devices, the loading and unloading process of the rolling door machine becomes more complex and time-consuming. The lack of precise adjustment and control provided makes the accuracy and convenience during the installation and adjustment process greatly reduced. The lack of a corresponding unlocking mechanism reduces the protection performance of internal parts and may shorten the service life of the equipment. Content of the Utility Model

Through the rotational design of the sealing sleeve 9 and the slope groove 10, the outer end of the clamping frame 7 is tightened into the clamping groove 5 along the slope of the slope groove 10. The clamping frame 7 can extend into the clamping groove 5 to compress the spring 6 to store energy in the spring 6, thereby sealing the clamping frame 7. On the contrary, rotate the rotating sleeve 8 in the opposite direction, and use the energy stored in the spring 6 to release the clamping frame 7. If it is not completely ejected, the unlocking block 13 can be pushed in cooperation with the unlocking tube 12, so as to push the clamping frame 7 out of the clamping groove 5 to achieve rapid loading and unloading.
