Description

Technical Field

[0001] This utility model relates to the field of fencing technology, specifically a mobile fencing. Background Technology

[0002] A fencing fence is a component or system primarily composed of a mesh structure used for protection, isolation, or capture. It forms a continuous boundary by appropriately fixing and connecting mesh materials to enclose, protect, and restrict objects or spaces within a specific area. For example, a safety fencing fence for construction pits is mainly used to ensure the safety of the construction site. These fences are typically woven or welded from high-strength metal wires, possessing excellent impact resistance and durability. The design and materials of fencing vary greatly depending on the usage environment and functional requirements. Materials may include metal wire, plastic wire, and synthetic fibers. Corrosion protection and maintenance treatments such as electroplating, hot-dip galvanizing, powder coating, and dip coating can be applied to adapt to long-term use under different climatic and environmental conditions.

[0003] Patent application CN201821792298.4 discloses a fencing device, which includes a fencing net and multiple sets of connecting components. The fencing net includes a net body and a first connecting portion, which is fixedly connected to one edge of the net body. Multiple sets of connecting components, each including a first connector and a second connector, are also included. The second connector is detachably connected to one surface of the first connecting portion, and the first connector is fixedly connected to the second connector. The first connector is used to detachably connect to a metal cabinet, thereby fixing the fencing net body to the metal cabinet. By setting the above-mentioned fencing device, the fencing net is connected to the metal cabinet via the connecting components. The fencing net can be fixed to the surface of the metal cabinet by setting the connecting components at multiple locations on the metal cabinet, and the fencing net is detachably connected to the connecting components via the first connecting portion. Thus, compared to carrying a fixed pole, the portability of the fencing device is improved. The connecting components are detachably connected to the metal cabinet, making the installation, disassembly, and adjustment of the fencing more convenient. Based on the above patent search and combined with the existing fencing technology, it was found that fencing usually lacks the necessary flexibility in application, and cannot be easily moved or adjusted, causing inconvenience to users. In addition, the stability of the fencing is also problematic. Once placed in a humid environment, its internal rollers and other displacement components are prone to corrosion, seriously affecting its normal use function. Utility Model Content

[0004] The purpose of this invention is to provide a mobile fencing system to solve the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mobile fencing, comprising a frame, with a fencing body fixedly installed inside the frame. A displacement mechanism is provided below the frame, the displacement mechanism comprising a base, a bearing ring, a rotating rod, a support column, a first shaft, a first wheel, a second shaft, a second wheel, and an adjusting plate.

[0011] Optionally, a cover plate is inserted into the bottom of the floor base, and the cover plate and the cover plate slot are in an insert-in relationship.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention includes a displacement mechanism. In terms of displacement function, the coordinated operation of the base, bearing rings, rotating rod, and support column enables the lever to drive the support column, pushing the first shaft, first wheel, second shaft, and second wheel to extend or retract in groups. The adjusting plate and bearing pad cooperate, and the threaded seat and limiting screw lock the position, thereby enabling rapid activation and controllable displacement of the grid frame and enclosure, facilitating convenient switching and fixing between different positions. Regarding stability and durability, the limiting rod, first limiting support rod, second limiting support rod, first limiting slide groove, and second limiting slide groove together limit the movement range of the rotating rod and support column. The base, in conjunction with the cover plate slot and sealing plate, protects the internal parts, reducing the risk of moisture corrosion to the bearings and wheels. Simultaneously, multiple sets of bearing rings and wheels (first wheel and second wheel) distribute the force, ensuring uniform force distribution and overall stability during movement and storage.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-7In this embodiment of the utility model, a mobile fencing includes a frame 1, with a fencing body 2 fixedly installed inside the frame 1. A displacement mechanism 3 is provided below the frame 1. The displacement mechanism 3 includes a base 301, a bearing ring 302, a rotating rod 303, a support column 304, a first shaft 305, a first wheel 306, a second shaft 307, a second wheel 308, and an adjusting plate 309. The base 301 is fixedly installed at the lower end of the frame 1, and a bearing ring 302 is fixedly installed on the inner wall of the base 301. A rotating rod body 303 is installed on the 02. A support column 304 is fixedly installed in the middle of the rotating rod body 303. A first shaft 305 and a second shaft 307 are fixedly installed at the lower end of the support column 304. A first wheel body 306 is installed on the first shaft 305, and a second wheel body 308 is installed on the second shaft 307. An adjusting plate 309 is provided on the outer side of the support column 304. The displacement mechanism 3 also includes a lever 310, a limiting rod 311, a first limiting support rod 312, a second limiting support rod 313, a first limiting slide groove 314, and a second limiting slide groove 315. The base 301 has a groove 315, a bearing pad 316, a threaded seat 317, a limiting screw 318, a cover plate 319, and a cover plate slot 320. A first limiting groove 314, a second limiting groove 315, and a cover plate slot 320 are provided on the inner wall of the floor base 301. A lever 310 is fixedly installed on the adjusting plate 309. A limiting rod 311 is fixedly installed on the left end of the adjusting plate 309. A first limiting support rod 312 is fixedly installed at the rear end of the limiting rod 311, and a second limiting support rod 313 is fixedly installed at the front end of the limiting rod 311. The position support rod 312 is slidably connected to the first limiting slide groove 314, and the second limiting support rod 313 is slidably connected to the second limiting slide groove 315. A bearing pad 316 is fixedly installed on the right end of the adjusting plate 309. A threaded seat 317 is provided above the bearing pad 316. The threaded seat 317 is fixedly installed on the outer wall of the floor seat 301. A limiting screw 318 is threadedly connected to the inner side of the threaded seat 317. A cover plate 319 is inserted into the bottom end of the floor seat 301. The cover plate 319 is inserted into the cover plate slot 320.

[0026] The base 301 is the foundation of the displacement mechanism 3, providing stable support for the space frame 1 and the enclosure 2. The bearing ring 302 provides support and reduces friction, allowing the rotating rod 303 and the support column 304 to rotate smoothly. The rotating rod 303 connects the bearing ring 302 and the support column 304, transmitting force and rotation angle. The first shaft 305, the first wheel 306, the second shaft 307, and the second wheel 308 form a displacement structure that can drive the overall displacement of the space frame 1 and the enclosure 2. The adjusting plate 309 controls the movement of the support column 304. The movement can be achieved by using the lever 310 on the adjusting plate 309. The left and right movement of the support column 304 unfolds the first shaft 305, the first wheel 306, the second shaft 307, and the second wheel 308, allowing the space frame 1 and the enclosure 2 to move. The limiting support rod and the limiting slide groove form a limiting device to restrict the movement range of the rotating rod 303 and the support column 304. The threaded seat 317 and the limiting screw 318 form a limiting adjustment device to adjust the position of the limiting rod 311, thereby adjusting the movement range of the displacement mechanism 3. The cover plate 319 is used to protect the internal parts of the displacement mechanism 3, prevent corrosion caused by a humid environment, and extend the service life of the displacement mechanism 3.

[0027] The working principle of this utility model is as follows: This mobile fence is equipped with a displacement mechanism 3. When using this mobile fence, the frame 1 and the fence body 2 serve as the main body of the fence, while the displacement mechanism 3 is a displacement structure. When activating the displacement mechanism 3, first remove the cover plate 319, then manually push the adjusting plate 309 and the bearing pad 316 to the left, so that the lever 310 on the adjusting plate 309 will drive the support column 304 to move to the left. The first limiting support rod 312 and the first limiting slide groove 314 are in a sliding connection relationship, and the second limiting support rod 313 and the second limiting slide groove 315 are in a sliding connection relationship. Under the influence of the relationship, multiple sets of bearing rings 302, rotating rods 303, support columns 304, first shafts 305, first wheel bodies 306, second shafts 307, and second wheel bodies 308 will protrude from the landing base 301, achieving the effect of supporting the space frame 1 and the enclosure 2. Then, rotate the limiting screw 318 to fix the position of the bearing pad 316 and the adjusting plate 309, at which point the space frame 1 and the enclosure 2 can be pushed. When closing the displacement mechanism 3, first select to rotate the limiting screw 318 so that the limiting screw 318 no longer fixes the bearing pad 316 and the adjustment plate 309. Adjusting the position of the adjusting plate 309, pulling the adjusting plate 309 to the right causes the lever 310 on the adjusting plate 309 to drive the support column 304 to move to the right. Under the influence of the sliding connection between the first limiting support rod 312 and the first limiting slide groove 314, and the sliding connection between the second limiting support rod 313 and the second limiting slide groove 315, multiple sets of bearing rings 302, rotating rod body 303, support column 304, first shaft 305, first wheel body 306, second shaft 307, and second wheel body 308 are retracted into the interior of the floor seat 301. At this time, the cover plate 319 is then closed. Inserted into the base 301, it achieves the effect of protecting the internal parts of the base 301; in summary, the displacement mechanism 3 adopts an adjustable displacement structure, which can selectively enable the displacement function. In the enabled state, it can drive the grid frame 1, the enclosure 2 and the displacement mechanism 3 to move as a whole, thereby achieving the displacement effect. In the closed state, the base 301 supports the grid frame 1 and the enclosure 2, achieving the ground support effect, ensuring the stability of the grid frame 1 and the enclosure 2, and the closure of the cover plate 319 provides protection for the displacement structure, effectively reducing the probability of rust on the displacement structure.
