DETAILED DESCRIPTION

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0036] Example 1

[0037] like Figure 1 As shown, an embodiment of the present invention provides a portable fence, which includes a left support 100 and a right support 200 arranged in parallel. The left support 100 and the right support 200 are connected by at least one group of beam assemblies 400. The beam assembly 400 is arranged perpendicular to the left support 100. The beam assembly 400 includes a connecting sleeve 410 rotatably connected to the left support 100, a connecting rod 430 fixedly connected to the right support 200, and a telescopic piece 420. The connecting sleeve 410 is cylindrical, and the telescopic piece 420 is conical and spirally arranged. The outer end of the expansion piece 420 is fixedly connected to the inside of the connecting sleeve 410, and the inner end of the expansion piece 420 is fixedly connected to the connecting rod 430. A square flexible baffle 500 is also provided between the left support 100 and the right support 200. A construction mark is provided on the flexible baffle 500. The two ends of the flexible baffle 500 are respectively fixedly connected to the left support 100 and the right support 200. The left support 100 and the right support 200 are also provided with a support leg assembly 300 to support the left support 100 and the right support 200 to stand on the ground.

[0038] In this embodiment, if Figure 1 、 Figure 5 and Figure 6 As shown, in the unfolded state, the beam assembly 400 is in an extended state. At this time, the flexible baffle 500 is tensioned, and the construction mark on the flexible baffle 500 can be clearly displayed to serve as a warning. At the same time, the distance between the left support 100 and the right support 200 is longer, and the flexible baffle 500 also serves as a shield. The support leg assembly 300 supports the left support 100 and the right support 200 to stand at the construction site. A combination of multiple fences can surround the construction site to protect the construction. When in the retracted state, the left support 100 and the right support 200 are pressed to cause the expansion piece 420 to contract, and the connecting rod 430 to retract into the connecting sleeve 410. At this time, the expansion piece 420 is in a spiral shape, and the length of the beam assembly 400 is greatly shortened. Then, the left support 100 and the right support 200 can be fixed by wrapping a rope or a flexible baffle 500 around the left support 100, so that the volume of the fence is greatly reduced, making it easy to carry.

[0039] The portable fence disclosed in the embodiment of the present utility model connects the left support 100 and the right support 200 through a retractable beam assembly 400. When in use, the beam assembly 400 is extended, so that the flexible baffle 500 connected to the left support 100 and the right support 200 is unfolded to act as a fence. When not in use, the beam assembly 400 is shortened, and the distance between the left support 100 and the right support 200 is shortened, and the volume of the fence is greatly reduced, thereby increasing the portability of the fence.

[0040] Specifically, in this embodiment, Figure 2 、 Figure 3 and Figure 5 As shown, the connecting sleeve 410 is a cylindrical structure, and one end of the connecting sleeve 410 is provided with an outer retaining ring, and the outer retaining ring is installed on the left support 100 through a limit plate 440. A countersunk structure is provided on the side where the limit plate 440 is connected to the left support 100, and the limit plate 440 is fixedly connected to the left support 100 by screws or welding. The outer retaining ring is rotatably connected to the countersunk hole of the limit plate 440, and the limit plate 440 presses the outer retaining ring on the left support 100, so that the connecting sleeve 410 can only rotate on the left support 100. The telescopic piece 420 has a conical spiral structure in its natural state, and has a vortex structure in its compressed state (see the structure of the magic bullet wand in the prior art). When the fence is in use, the expansion piece 420 pops out to tighten the flexible baffle 500, thereby showing the construction mark on the flexible baffle 500. The connecting rod 430 is in the shape of a round rod. Both ends of the expansion piece 420 are fixedly connected to the inner wall of the connecting sleeve 410 and the outer wall of the connecting rod 430 by welding. A fixing plate 450 is provided at one end of the connecting rod 430. The fixing plate 450 is a plate-shaped structure. The connecting rod 430 is connected to the fixing plate 450 through a threaded structure. For example, an external thread is provided on the connecting rod 430, and a threaded sleeve is welded on the fixing plate 450. The external thread of the connecting rod 430 is connected to the threaded sleeve, and the fixing plate 450 is fixedly connected to the right support 200 by screws or welding.

[0041] In this embodiment, two groups of the crossbeam assemblies 400 are provided to increase the stability of the left support 100 and the right support 200 .

[0042] Example 2

[0043] As one of the embodiments of the utility model, Figure 2 and Figure 4As shown, the difference between this embodiment and embodiment 1 is that the left support 100 and the right support 200 are both hollow square cylinders, a roller 700 is provided in the right support 200 to wind the flexible baffle 500, the flexible baffle 500 is a waterproof cloth, the roller 700 is rotatably connected to the right support 200, and the two ends of the right support 200 are fixedly connected to the inner cover 800 by screws or welding, the end of the roller 700 is rotatably connected to the inner cover 800, and a screw is provided between the end of the roller 700 and the inner cover 800. There is a vortex spring. After the flexible baffle 500 is extended, the flexible baffle 500 drives the roller 700 to rotate. At this time, the vortex spring contracts. After the fence is used, the flexible baffle 500 is released. The roller 700 automatically wraps around the flexible baffle 500 under the action of the restoring force of the vortex spring, thereby storing the flexible baffle 500. The end of the flexible baffle 500 away from the roller 700 passes through the side wall of the right support 200 and is fixedly connected to the left support 100. The flexible baffle 500 is slidably connected to the right support 200.

[0044] Specifically, the right support 200 is provided with a strip hole, the flexible baffle 500 passes through the strip hole, the inner cover 800 is a square cover structure, and a cylindrical mounting seat is provided on one side of the inner cover 800 located inside the right support 200. The end of the roller 700 is fixed to the mounting seat by a volute spring, and the two ends of the volute spring are stuck in the end of the roller 700 and the mounting seat. One end of the flexible baffle 500 is fixedly connected to the roller 700 by gluing, and the other end of the flexible baffle 500 is fixedly connected to the left support 100 by gluing.

[0045] Preferably, a through-hole structure is provided on the side of the left support 100 close to the right support 200, and the crossbeam assembly 400 is fixedly connected to the inner side of the left support 100. The length of the crossbeam assembly 400 after contraction is less than the width of the left support 100, so that the crossbeam assembly 400 can be completely retracted into the left support 100 when contracted, so that when the crossbeam assembly 400 is contracted, the crossbeam assembly 400 can be completely placed in the left support 100, and the left support 100 and the right support 200 fit together, so that the shape of the fence after contraction is more regular, making it easier to store and carry, and the telescopic assembly 400 passes through the through-hole structure when extended.

[0046] Example 3

[0047] As one of the embodiments of the utility model, this embodiment is different from embodiment 1 in that the support leg assembly 300 is detachably connected to the left support 100 and the right support 200. When in use, the support leg assembly 300 is tiltedly installed on the left support 100 and the right support 200 so that the left support 100 and the right support 200 can stand on the ground. When not in use, the support leg assembly 300 is removed, so that the fence has a more regular shape when not in use, which is convenient for storage.

[0048] Specifically, in this embodiment, Figure 7 As shown, the support leg assembly 300 includes a supporting leg 310, a fixed end 320 and a connecting plate 330. The supporting leg 310 is a square rod. The connecting plate 330 is fixedly connected to the end of the supporting leg 310 by welding. The axis of the supporting leg 310 and the connecting plate 330 are inclined. At least one (two in this embodiment) fixed end 320 is provided on the side of the connecting plate 330 away from the fixed end 320. The fixed end 320 is made of elastic material and has an elliptical cylindrical structure. The side of the fixed end 320 is fixed to the connecting plate 330 by welding or screw connection. The left support 100 and the right support 200 are provided with a strip hole that cooperates with the fixed end 320. The fixed end 320 is inserted into the strip hole. Since the fixed end 320 is elliptical, the fixed end 320 is clamped in the strip hole, so that the connecting plate 330 fits on the left support 100 / right support 200.

[0049] The fixed end 320 is formed by bending a strip of elastic sheet. First, it is bent into a V shape, and then the two ends are bent 90 degrees. If the fixed end 320 is installed by screws, screw holes are punched at both ends of the fixed end 320. If welding is used for installation, there is no need to punch screw holes. Then, the bent two ends of the fixed end 320 are brought close to each other and fixed to the fixed end 320. At this time, the portion of the fixed end 320 that cooperates with the left support 100 / right support 200 is elliptical under the action of elasticity. When installing the support leg assembly 300, the fixed end 320 is inserted into the strip hole on the left support 100 / right support 200. When retracting the fence, the support leg assembly 300 can be pulled out.

[0050] As a preferred implementation in this embodiment, the fence further includes an outer cover 600. The outer cover 600 is in a cover shape. When the crossbeam assembly 400 is retracted, the outer cover 600 is fixedly connected to the ends of the left support 100 and the right support 200 to fix the two, thereby fixing the left support 100 and the right support 200.

[0051] Specifically, the left support 100 and the right support 200 are both square cylindrical, and the outer cover 600 is square cover-shaped. The outer cover 600 covers the ends of the left support 100 and the right support 200. The elastic force of the crossbeam assembly 400 presses the left support 100 / the right support 200 against the inner wall of the outer cover 600, so that the left support 100 and the right support 200 are fixedly connected to the outer cover 600. The outer cover 600 is sleeved on the ends of the left support 100 and the right support 200.

[0052] Preferably, Figure 2 As shown, a cylindrical fixing seat is further provided on the inner side of one end of the outer cover 600 connected to the left support 100, and the support leg assembly 300 is connected to the cylindrical fixing seat by interference fit, so that the support leg assembly 300 can be stored in the left support 100, so that the fence has a regular shape after being folded and forms an integral structure;

[0053] Specifically, the fixing seat is in the shape of a square cylinder, and is fixed to the outer cover 600 by welding, and the supporting legs 310 are inserted into the fixing seat.
