A first strong magnetic strip 18 and a limiting pin 17 are fixedly connected to the right end of the fencing frame 2. A limiting groove 21 is formed at the left end of the fencing frame 2, and a second strong magnetic strip 20 is fixedly connected to the left edge of the limiting groove 21. Two sets of connecting frames 19, symmetrically distributed, are fixedly connected to the center of the rear end of the fencing frame 2. Support legs 3 are rotatably mounted on the connecting frames 19, and a second hinge frame 12 is rotatably mounted on the lower end of the support legs 3. A threaded sleeve 4 is hinged on the hinge frame 12. A first hinge frame 6 is fixed to the upper edge of the bearing base 1. One end of two sets of connecting parts 7 is hinged on the first hinge frame 6. The other end of the two sets of connecting parts 7 is hinged to the lower end of the enclosure frame 2. Two sets of extension frames 8 are symmetrically distributed on the left and right sides and fixed to the upper end of the bearing base 1. A guide rail 10 is fixed between the two sets of extension frames 8. The outer wall of the rear end of the guide rail 10 is provided with an external thread 23. A threaded locking ring 22 is fitted on the outer wall of the guide rail 10. A sliding groove 11 is opened through the front and rear ends of the movable frame 5. A threaded column 9 is fixed to the center of the upper end of the movable frame 5.

[0017] The first strong magnetic strip 18 and the second strong magnetic strip 20 provide initial adsorption force, which, together with the limiting pin 17 and the limiting groove 21, forms a mechanical stop. This allows for plug-and-play connection while preventing slippage of traditional magnetic connections under vibration or lateral force. The hinged enclosure frame 2, support legs 3 and load-bearing base 1 allow the enclosure frame 2 to be adjusted in angle according to the needs of enclosure construction in different terrains, thereby improving its adaptability to various terrain environments.

[0018] Please see Figures 5-6In this embodiment, the front and rear ends of the enclosure frame 2 are provided with mounting grooves 15. Two sets of protective net panels 14 and one set of enclosure panels 16 are installed in the mounting grooves 15. The protective net panels 14 and the enclosure panels 16 can effectively block stones and dust in the construction site. The two sets of protective net panels 14 are symmetrically distributed front and back, and the enclosure panels 16 are located between the two sets of protective net panels 14. The two sets of enclosure panels 16 can block foreign objects inside and outside the site to protect the enclosure panels 16.

[0019] Please see Figures 3-4 In this embodiment, the inner wall of the slide groove 11 fits against the outer wall of the guide rail 10, the threaded column 9 is adapted to the threaded sleeve 4, and the slide groove 11, in conjunction with the guide rail 10, can provide limiting assistance for the movable frame 5 that moves back and forth along the outer wall of the guide rail 10, so as to improve the stability of the enclosure frame 2 during rotation and storage. The threaded locking ring 22 is threadedly adapted to the external thread 23, the rear end of the threaded locking ring 22 fits against the front end of the movable frame 5, and the inner wall of the threaded locking ring 22 fits against the outer wall of the guide rail 10. The threaded locking ring 22 can fix the enclosure frame 2 that moves back and forth along the outer wall of the guide rail 10.

[0020] Please see Figures 4-6 In this embodiment, the first strong magnetic strip 18 and the second strong magnetic strip 20 are adapted to each other, and the limiting pin 17 and the limiting groove 21 are adapted to each other. The adapted first strong magnetic strip 18 and the second strong magnetic strip 20, as well as the limiting pin 17 and the limiting groove 21, can assist multiple sets of enclosure frames 2 to be quickly assembled and spliced ​​in the left and right directions. The first strong magnetic strip 18 and the second strong magnetic strip 20 are both made of neodymium iron boron. Two sets of handles 13 are fixedly connected to the center of the outer wall of the threaded sleeve 4, which are symmetrically distributed in the front and back. The handles 13 can facilitate the user to manually rotate the threaded sleeve 4 to connect with the threaded post 9.

[0021] In use, first place the support base 1 on the ground, and fix the lower end of the enclosure frame 2 by hinge and fasten the first hinge frame 6 and the connector 7 to form an adjustable angle support structure. At the same time, rotate the support leg 3 to the vertical position, and connect it to the threaded sleeve 4 by the second hinge frame 12. Then rotate the handle 13 to thread the threaded sleeve 4 onto the threaded post 9 so that the support leg 3 can be installed on the movable frame 5 to push the support leg 3 to unfold outward until the lower end of the support leg 3 is rotated and adjusted to a suitable position and provides stable support for the enclosure frame 2. Next, slide the slide groove 11 of the movable frame 5 along the guide rail 10 to the last end, so that the rear end of the movable frame 5 fits against the inner wall of the rear end of the extension frame 8. Then rotate the threaded locking ring 22 to engage with the external thread 23, so that the rear end of the threaded locking ring 22 presses the front end of the movable frame 5 to lock the position of the movable frame 5. At this time, the threaded column 9 and the threaded sleeve 4 form a rigid connection, further enhancing the support stability. When multiple enclosure frames 2 need to be assembled, the right end limiting pin 17 of enclosure frame 2 is aligned with the limiting groove 21 of another enclosure frame 2. At the same time, the first strong magnetic strip 18 and the second strong magnetic strip 20 are attracted and attached. The cooperation between the limiting pin 17 and the limiting groove 21 can prevent horizontal sliding. The neodymium iron boron strong magnetic strip provides vertical attraction force to achieve rapid positioning and connection. When storing the enclosure frame 2, first rotate the threaded locking ring 22 counterclockwise to loosen the movable frame 5, then rotate the handle 13 in the opposite direction to lower the threaded sleeve 4 and fold the support leg 3 inward. Then apply a horizontal pulling force to disengage the limiting pin 17 from the limiting groove 21. At the same time, the strong magnetic strip attraction force is overcome, completing the separation of adjacent enclosures for easy transportation and reuse.

[0022] Through the above steps, the first strong magnetic strip 18 and the second strong magnetic strip 20 provide initial adsorption force, which, together with the limiting pin 17 and the limiting groove 21, forms a mechanical stop. This allows for plug-and-play connection while preventing slippage of traditional magnetic connections under vibration or lateral force. The hinged enclosure frame 2, support legs 3, and load-bearing base 1 allow the enclosure frame 2 to be adjusted according to the needs of different terrains during enclosure construction, thereby improving its adaptability to various terrain environments and solving the problem that temporary enclosures at existing construction sites are inconvenient to fold, store, and quickly assemble.

[0023] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
