[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0029] Example 1

[0030] Reference Figure 1-2, which is the first embodiment of the present invention, and provides a quick retractor for a safety fence, including a fence body 100, having a head end and a tail end, for forming an isolation belt around a specific area; an elastic member 101, for connecting with the head end of the fence body 100; a cross arm 102, the cross arm 102 is fixed to the first section of the elastic member 101, and the cross arm 102 is used to support and guide the orderly deployment or folding of the fence body 100; an anti-detachment hook 103, which is arranged at one end of the cross arm 102 away from the elastic member 101, and is used to fix the tail end of the fence body 100; a V-shaped hook 104, the V-shaped hook 104 is fixed to the second end of the elastic member 101, the V-shaped hook 104 is adapted to the anti-detachment hook 103, and can be disconnected when necessary to adjust the layout length of the fence body 100.

[0031] In this embodiment, the main body 100 of the fence is composed of a series of interconnected meshes, which are usually made of high-strength materials such as polyethylene or nylon, ensuring that good durability and elasticity can be maintained under adverse weather conditions. The main body 100 of the fence can form a continuous isolation belt when unfolded, effectively isolating the construction site from the outside world. The cross arm 102 is fixedly connected to the first section of the elastic member 101. The cross arm 102 not only provides lateral support when the main body 100 of the fence is unfolded, but also plays a guiding role, ensuring that the main body 100 of the fence can move smoothly along the predetermined path during the unfolding process, avoiding jamming or entanglement caused by improper folding. The anti-detachment hook 103 is arranged on the side of the cross arm 102 away from the elastic member 101 to prevent the main body 100 of the fence from accidentally falling off during use. The design of the anti-detachment hook 103 usually has a certain locking mechanism, and can be easily unlocked when the layout length of the main body 100 of the fence needs to be adjusted, thereby achieving the purpose of quick adjustment. The V-shaped hook 104 is fixed to the second end of the elastic member 101 and matches the anti-detachment hook 103. This design allows the user to adjust the effective length of the fence body 100 at any time according to actual needs. For example, when encountering an obstacle and needing to bypass it, the position of the fence body 100 can be repositioned by unhooking the V-shaped hook 104, and then reconnecting the V-shaped hook 104 to complete the adjustment.

[0032] When the main body 100 of the fence needs to be unfolded, the operator first unties the connection between the anti-drop hook 103 and the V-shaped hook 104, and then pulls the main body 100 to unfold it along the cross arm 102. This avoids jamming or entanglement caused by improper folding. As the main body 100 of the fence is gradually unfolded to the desired position, the tail end is fixed by the anti-drop hook 103, and the V-shaped hook 104 is locked with the anti-drop hook 103 again, completing a complete layout of the main body 100 of the fence.

[0033] On the contrary, when it is necessary to fold up the main body 100 of the fence, the above steps can be reversed. First, the connection between the anti-drop hook 103 and the V-shaped hook 104 is released, and then the main body 100 of the fence is slowly retracted until it is completely retracted to the initial state. During the whole process, the cross arm 102 serves as a supporting structure to ensure that the main body 100 of the fence can be unfolded and folded smoothly and unimpeded.

[0034] Moreover, when the fence main body 100 needs to be dried after being wetted by rain, the V-shaped hook 104 can be directly hung outdoors for drying, which is convenient to use.

[0035] Example 2

[0036] Reference Figure 1-2 , which is the second embodiment of the present invention, and provides a quick retractor for a safety fence, including an elastic member 101 made of a highly elastic material so that it can be deformed when not subjected to external force to drive the V-shaped hook 104 to separate from the anti-detachment hook 103. The anti-detachment hook 103 has an anti-detachment hole, and is locked when the tail end of the fence body 100 is inserted into the anti-detachment hole. The fence body 100 is provided with a plurality of evenly spaced annular eyelets for cooperating with the cross arm 102. The V-shaped hook 104 and the anti-detachment hook 103 constitute a manual buckle, allowing the user to manually release the tail end of the fence body 100 in order to adjust the layout length of the fence; the cross arm 102, the anti-detachment hook 103, and the elastic member 101 are made in one piece. The elastic member 101 is set as a plurality of concentric rings surrounding each other, and a gap is left between the concentric rings and the V-shaped hook 104 so that the head end of the fence body 100 can be inserted and fixed.

[0037] In this embodiment, the elastic member 101 is made of a highly elastic material and can be deformed freely under the action of external force. This design increases the flexibility of operation. The elastic member 101 is a concentric ring structure surrounded by multiple sections, and a certain gap is maintained between each section. Such a structural design allows the front end of the enclosure body 100 to be easily inserted and fixed. At the same time, when the enclosure body 100 needs to be released, the elastic property makes it easier to separate the V-shaped hook 104 from the anti-detachment hook 103. The anti-detachment hook 103 has an anti-detachment hole. When the rear end of the enclosure body 100 is inserted into the hole, the locking function can be realized. Such a design ensures the stability of the enclosure body 100 during use and prevents it from being detached due to accidental slippage. In addition, the anti-detachment hook 103 and the V-shaped hook 104 together constitute a manual buckle mechanism, and the user can release the enclosure body 100 through manual operation, thereby adjusting the layout length of the enclosure body 100 according to actual needs. The main body 100 of the fence is provided with a plurality of evenly spaced annular eyelets, which are used to cooperate with the cross arm 102 so that the main body 100 of the fence can be hung on the cross arm 102 in an orderly manner. The cross arm 102, the anti-drop hook 103 and the elastic member 101 are integrated, which means that they are manufactured in the same production process. Such a design reduces the assembly steps, simplifies the production process, and improves the durability of the product.

[0038] Example 3

[0039] Reference Figure 1 and Figure 3 , which is the third embodiment of the present invention, provides a quick retractor for a safety fence, including an elastic member 101 configured as a bow-shaped frame, and a detachably connected compression spring 200 is provided inside the bow-shaped frame. A cross arm 102 is provided with a plurality of hanging points 201 arranged at intervals, and the hanging points 201 are used to mount the fence body 100 in sequence and in sections.

[0040] In this embodiment, the elastic member 101 is designed as an arched frame, which has a good elastic pulling effect. A detachably connected compression spring 200 is arranged inside the arched frame. The function of the compression spring 200 is to prevent the anti-drop hook 103 and the V-shaped hook 104 from separating. Under the action of the compression spring 200, the two can be automatically separated, so that the staff can readjust the length of the fence body 100.

[0041] When the compression spring 200 ages and becomes weak after long-term use, the user can compress the spring 200 better, thereby increasing the service life of the device. The compression spring 200 and the bow frame are connected in a detachable manner, and common implementation methods include but are not limited to using threaded fasteners, snap-on connections, or magnetic designs.

[0042] The cross arm 102 is provided with a plurality of hanging points 201 arranged at intervals, and the positions and numbers of these hanging points 201 can be adjusted according to actual needs to adapt to the fence body 100 of different lengths. The distances between the hanging points 201 are precisely calculated to ensure that the fence body 100 will not be damaged due to being too tight when hanging, nor will it be knotted or messed due to being too loose. Such a design allows the fence body 100 to be smoothly unfolded or folded along a predetermined track, which is convenient for installation as well as subsequent maintenance and disassembly.

[0043] The method of using the quick retractor for the safety fence is that first, the operator needs to unlock the connection between the anti-slip hook 103 and the V-shaped hook 104. This step allows the fence body 100 to be changed from a fixed state to an adjustable state. Then, by pulling the fence body 100, it is unfolded along the direction of the cross arm 102 to ensure that the fence body 100 is unfolded in an orderly manner to avoid jamming or entanglement caused by improper folding. As the fence body 100 gradually unfolds to the desired position, the operator should lock the V-shaped hook 104 with the anti-slip hook 103 to complete the layout of the fence body 100.

[0044] Operation steps for folding the main body 100 of the fence:

[0045] Similar to the unfolding, first release the locking state of the anti-drop hook 103 and the V-shaped hook 104, and then the operator can slowly retract the fence body 100 until it is completely retracted to the initial state.

[0046] The design of the elastic member 101 mentioned in Examples 2 and 3 (whether it is a multi-section concentric ring or a compression spring 200 in a bow-shaped frame) enhances the elasticity and durability of the equipment, while also facilitating rapid adjustment and long-term maintenance of the fence body 100.
