[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example: See Figures 1 to 6 According to an embodiment of the utility model, a technical solution is provided: a convenient, fast and easy to fold duty shielding cloth, comprising a storage column 1, a winding roller 4 and a shielding member 6, wherein the storage column 1 has a storage cavity 2 with openings 3 formed on both sides thereof, and preferably, the two openings 3 are arranged on the opposite side walls of the storage column 1; the winding roller 4 is arranged in the storage cavity 2 and is rotatably connected to the storage column 1, for example, the winding roller 4 can be rotatably connected to the storage column 1 through a bearing (not shown in the figure), and a clockwork spring 5 is arranged between the winding roller 4 and the storage column 1; the shielding member 6 is a flexible and curlable square sheet structure, for example, the shielding member 6 can be made of Oxford cloth, which has the advantages of wear resistance and scratch resistance, waterproof performance, UV resistance, lightness and portability, easy cleaning and maintenance, stable structure and strong adaptability as a shielding material. The middle part of the shielding member 6 is fixed on the winding roller 4. In this example, a through hole 21 is provided on the winding roller 4. The middle part of the shielding member 6 passes through and is fixed in the through hole 21 by a fixing screw 22; the two ends of the shielding member 6 extend from the two openings 3 of the storage column 1 respectively.

[0026] When using the duty shielding cloth of the above structure for physical shielding, two staff members can grasp the two ends of the shielding member 6 and apply force in opposite directions, so as to quickly unfold the shielding member 6 to form a fence for shielding. The unfolding area of ​​the shielding member 6 can be flexibly adjusted according to actual usage. Afterwards, it is only necessary to cancel the force applied to the shielding member 6, and the shielding member 6 can be quickly stored on the winding roller 4 of the storage cavity 2 under the rebound force of the clockwork spring 5.

[0027] In this exemplary embodiment, end caps 7 connected to the storage cavity 2 are fixedly provided at both ends of the storage column 1. The end caps 7 and the storage column 1 can be an integrated structure or a split structure. In order to facilitate the assembly of the clockwork spring 5, in this example, the end caps 7 and the storage column 1 are split structures, and the two are connected and fixed by means of a snap-fit. Specifically, an elastic hook 14 is provided on the end cap 7, and a snap-fit ​​hole 15 is provided on the storage column 1. The end cap 7 can be snap-fitted and fixed to the storage column 1 by the snap-fit ​​cooperation between the hook 14 and the snap-fit ​​hole 15; the clockwork spring 5 is arranged in the end cap 7, the first end of the clockwork spring 5 is fixed to the end cap 7, and the end of the winding roller 4 extends into the end cap 7 and is fixed to the second end of the clockwork spring 5. For example, the first end of the clockwork spring 5 and the end cap 7 can be fixedly connected by fasteners such as screws, and the winding roller 4 is provided with a snap-fit ​​socket 16 that snap-fits with the second end of the clockwork spring 5, and the second end of the clockwork spring 5 is snap-fitted and fixed in the snap-fit ​​socket 16.

[0028] In this exemplary embodiment, the two ends of the shielding member 6 extending from the opening 3 are concavely provided with notches 8, and a handpiece 9 is embedded and installed in the notch 8. By providing a hidden handpiece 9, it is not only convenient for the staff to stably grasp the two ends of the shielding member 6 and apply force, but also convenient for the shielding members 6 of adjacent duty shielding cloths to be seamlessly connected. In this example, in order to improve the comfort of gripping, the handpiece 9 adopts a cylindrical structure, and in order to improve the stability of force application, the notch 8 is set in the middle of the two ends of the shielding member 6.

[0029] In this exemplary embodiment, rigid support bars 10 are fixedly provided at both ends of the shielding member 6 extending from the opening 3. The material of the rigid support bars 10 may be glass fiber reinforced plastic. The rigid support bars 10 are arranged perpendicular to the unfolding direction of the shielding member 6 and are fixed to the handpiece 9. The provision of the rigid support bars 10 stabilizes the shape of the unfolded shielding member 6, ensuring that the shielding member 6 will not be excessively bent or deformed after being opened.

[0030] In this exemplary embodiment, a plurality of cutouts 11 extending toward the storage column 1 are provided in the notch 8, and the plurality of cutouts 11 are arranged at intervals perpendicular to the unfolding direction of the shielding member 6. The notch 11 is provided to form a plurality of elastically deformable sheet-shaped swing pieces 17 in the notch 8. When a worker reaches into the notch 8 to grasp the handpiece 9, the swing piece 17 is squeezed and bent to one side. At this time, the size of the notch 8 becomes larger, which is convenient for the worker to grasp the handpiece 9. When the worker's hand is withdrawn from the notch 8, the swing piece 17 can be automatically reset to reduce the size of the notch 8 and ensure the shielding effect of the shielding member 6.

[0031] In this exemplary embodiment, a warning word arrangement area 12 is provided on the side of the shielding member 6 facing the outside when in use. Corresponding warning slogans are posted or sprayed on the warning word arrangement area 12, for example, clear instructions such as "No shooting", "Keep distance", "Do not approach" may be included, so as to convey key safety instructions and behavioral norms in an intuitive and eye-catching manner, effectively guide the crowd, prevent potential risks, ensure order on the scene, and avoid unnecessary conflicts.

[0032] To further enhance the warning effect and nighttime recognition, in this exemplary embodiment, a fluorescent strip 13 is provided on the shielding member 6 located around the warning word arrangement area 12. The fluorescent strip 13 and the warning word form a visual synergy and complementarity, and together build a more comprehensive safety warning system.

[0033] In order to achieve the connection and convenient assembly of adjacent duty shielding cloths, in this exemplary embodiment, the shielding pieces 6 of adjacent duty shielding cloths are fixedly connected by concealed buckles. Specifically, a connecting strip 18 made of cloth can be provided at the first end of the shielding piece 6, a female buckle 19 of a concealed buckle can be provided at the end of the connecting strip 18, and a sub-buck 20 that can be buckled with the female buckle 19 can be provided at the second end of the shielding piece 6. The setting of the concealed buckle allows the staff to complete the stable connection of adjacent shielding pieces 6 by simply aligning and pressing without the aid of additional tools, which greatly shortens the time for on-site construction and removal.

[0034] Working principle: When the on-duty shielding cloth is needed, two staff members respectively grasp the handpieces 9 in the notches 8 at both ends of the shielding piece 6, and the staff members apply force in opposite directions to quickly unfold the shielding piece 6. As the shielding piece 6 unfolds, the warning word arrangement area 12 faces outward, clearly displaying warning signs such as "No shooting", "Keep distance", and "Do not approach", intuitively conveying safety instructions and behavioral norms, guiding the onlookers to comply with regulations, and reducing the risk of on-site conflicts. If it is necessary to expand the shielding range or form a continuous fence, the shielding pieces 6 of adjacent shielding cloths can be quickly spliced ​​together through concealed buckles. During splicing, the female buckle 19 at the end of the connecting strip 18 at the first end of one shielding piece 6 is aligned with the sub-buckle 20 at the second end of the other shielding piece 6 and pressed together to achieve connection. When the shielding task is completed or the shielding position needs to be adjusted, the staff member cancels the force applied to both ends of the shielding piece 6. At this time, the rebound force of the clockwork spring 5 begins to play a role, pushing the winding roller 4 to rotate, driving the shielding member 6 to be wound into the storage cavity 2; as the clockwork spring 5 continues to rebound, the shielding member 6 is wound on the winding roller 4 in an orderly and compact manner. Since the winding process is controlled by the clockwork spring 5, the shielding member 6 is folded quickly and neatly, which is convenient for subsequent carrying and storage.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
