AI Technical Summary
Traditional rigid limiting devices are prone to damaging items when used with flexible objects, have poor adaptability, and flexible limiting products are not stable and are prone to loosening and falling off.
A flexible limiting structure is designed, including a flexible belt, an opening and closing block, a limiting block and a clamping sleeve. It achieves rapid assembly and stable connection through magnetic adsorption and threaded connection. The flexible belt can be deformed to adapt to different shapes, and the connection stability is enhanced by reverse threads and resistance rings.
It enables rapid assembly and compact, stable connection of flexible limiting structures, adapts to various shapes, provides reliable limiting effect, protects the limited objects, and reduces the risk of loosening and falling off.

Abstract
Claims
1. A flexible stop structure, characterized by: include The flexible strip (1) deforms under pressure and has a fixed end and a movable end. At its fixed end, at least two first connecting holes (1.1) are provided that penetrate the flexible strip (1) along the thickness direction, and at its movable end, at least two second connecting holes (1.2) are provided that penetrate the flexible strip (1) along the thickness direction. The opening and closing block (2) includes a connecting part (2.1) and a ring of protrusions (2.2) formed at the outer edge of the connecting part (2.1) along the connecting part (2.1) toward the movable end of the flexible strip (1). The connecting part (2.1) can generate an attractive force with a magnetic object. The protrusions (2.2) form an installation groove (2.3) inside. The cross section of the installation groove (2.3) matches the cross section of the flexible strip (1) for the insertion of the movable end of the flexible strip (1). The limiting block (3) has its first end detachably connected to the protrusion (2.2) and its second end passes through the second connecting hole (1.2) to fix the position of the movable end of the flexible strip (1) in the mounting groove (2.3).
2. The flexible stop structure of claim 1, wherein: The outer wall of the limiting block (3) is provided with a first external thread (3.1), and the center of the first end face of the limiting block (3) is provided with a screwing notch (3.2). The protrusion (2.2) is provided with a first internal thread (2.2.1) corresponding to the second connecting hole (1.2). A torsional force is applied to the screwing notch (3.2) to drive the limiting block (3) to rotate. At the same time, the first external thread (3.1) is continuously screwed into the second internal thread (4.1.1) so that the second end of the limiting block (3) passes through the second connecting hole (1.2).
3. The flexible stop structure of claim 2, wherein: It also includes a clamping sleeve (4), which includes a tube body (4.1) and a pressing ring (4.2) that protrudes radially outward from the first end of the tube body (4.1). The second end of the tube body (4.1) is inserted into the second connecting hole (1.2) and is oriented toward the first internal thread (2.2.1). A second internal thread (4.1.1) is formed on the inner wall of the tube body (4.1). The thread direction of the second internal thread (4.1.1) is opposite to that of the first internal thread (2.2.1). The height of the end face of the pressing ring (4.2) facing the second end of the tube body (4.1) is less than the thickness of the flexible strip (1).
4. The flexible stop structure of claim 3, wherein: The outer wall of the tube body (4.1) is provided with a plurality of resistance rings (4.1.2) spaced axially around the outer wall of the tube body (4.1), and the outer diameter of the resistance rings (4.1.2) forms a peak at the maximum point. 4.1.3) The diameter of the peak (4.1.3) is larger than the diameter of the second connecting hole (1.2), and the connection between two adjacent resistance rings (4.1.2) forms a valley (4.1.4). The diameter of the valley (4.1.4) is smaller than the diameter of the second connecting hole (1.2). When the tube (4.1) is inserted into the second connecting hole (1.2), the peak (4.1.3) squeezes the inner wall of the second connecting hole (1.2). At the same time, under the pressure, the inner wall of the second connecting hole (1.2) bulges towards the valley (4.1.4), so that the connection surface between the tube (4.1) and the second connecting hole (1.2) presents a connection surface with an "S" shaped cross section.
5. The flexible stop structure of claim 1, wherein: It also includes a reinforcing collar (5), which is inserted into the first connecting hole (1.1) and has an insertion interface (5.1) at its center. Both ends of the reinforcing collar (5) are provided with end guards (5.2) extending radially outward, and the end guards (5.2) cover the edge of the first connecting hole (1.1).
6. The flexible stop structure of claim 5, wherein: The reinforcing collar (5) and the end guards (5.2) located at both ends of it are integrally formed.
