[0035] like Figure 1-Figure 10 As shown:

[0036] A fence quick disassembly and assembly device, comprising a quick-installation mounting member 3 and a matching mounting member 4 mounted on the outside of a column 1, and a quick-installation bolt 6 mounted on an outer frame 201 of a fence 2, wherein the quick-installation bolt 6 cooperates with the quick-installation mounting member 3 and the matching mounting member 4 to realize quick disassembly and assembly of the fence 2;

[0037] The quick-install mounting member 3 includes a first fixing frame 301 and an inner plate 303. The inner plates 303 are fixedly mounted on the inner side surfaces opposite to the first fixing frame 301. A gap is provided between the inner plate 303 and the first fixing frame 301. A straight groove 304 for the limiting portion 605 of the quick-install bolt 6 to enter and a through groove 305 for the clamping portion 604 to pass are provided on the opposite side of the first fixing frame 301. A movable clamp 307 and a stop plate 3012 for limiting the rotation of the movable clamp 307 are rotatably connected in the gap between the inner plate 303 and the first fixing frame 301. The cooperation between the movable clamp 307 and the straight groove 304 is used to limit the clamping portion 604.

[0038] The matching installation member 4 includes a second fixing frame 401 , and a limiting groove 403 is formed on the inner side of an opposite end of the second fixing frame 401 .

[0039] In an optional embodiment, one end of the screw rod 601 passes through the outer frame 201 of the enclosure 2 and is fixed by a nut 602 , and the diameter of the engaging portion 604 is greater than the diameter of the limiting portion 605 .

[0040] In an optional embodiment, threaded holes 5 are formed on the inner sides of one end of the first fixing bracket 301 and the second fixing bracket 401 .

[0041] In an optional embodiment, a rotating shaft 306 is installed in the gap between the inner plate 303 and the first fixing frame 301 , and the movable clamp 307 rotates through the rotating shaft 306 .

[0042] In an optional embodiment, a first limiting shaft 308 is fixedly connected in the gap between the inner plate 303 and the first fixing frame 301 , and the first limiting shaft 308 is used to limit the rotation angle of the movable clamp 307 .

[0043] In an optional embodiment, a first torsion spring fixing shaft 309 is fixedly connected in the gap between the inner plate 303 and the first fixed frame 301, and a first torsion spring 3010 is sleeved on the outer side of the first torsion spring fixing shaft 309. One end of the first torsion spring 3010 abuts against the movable clamp 307, and the other end of the first torsion spring 3010 abuts against the second limiting shaft 3011. The second limiting shaft 3011 is fixed in the gap between the inner plate 303 and the first fixed frame 301.

[0044] In an optional embodiment, the inner side of one end of the support plate 3012 rotates around the outer side of the smooth portion of one of the fastening bolts 302, and an arc groove 3017 is opened on the inner side of the other end of the support plate 3012. The inner space of the arc groove 3017 is provided with a third limiting axis 3013, and the third limiting axis 3013 is fixed in the gap between the inner plate 303 and the first fixing frame 301.

[0045] In an optional embodiment, if Figure 3 , Figure 5 and Figure 6 As shown, an inner plate 303 is fixedly connected to the first fixing frame 301 by five fastening bolts 302, wherein four fastening bolts 302 are distributed at the four corners of the inner plate 303. It is recommended to rotate the abutment plate 3012 around the fastening bolts 302 at non-corners. A second torsion spring fixing shaft 3014 is fixedly connected in the gap between the inner plate 303 and the first fixing frame 301. A second torsion spring 3015 is sleeved on the outer side of the second torsion spring fixing shaft 3014. One end of the second torsion spring 3015 abuts against the outer side of one end of the abutment plate 3012, and the outer side of the other end of the second torsion spring 3015 abuts against the fourth limit bearing 3016. The fourth limit bearing 3016 is fixed in the gap between the inner plate 303 and the first fixing frame 301.

[0046] In this embodiment: first, the column 1 needs to be fixed on the ground. The column 1 is fixed on the target ground by the base 101 fixed on the bottom of the column 1. The quick-installation mounting part 3 and the matching mounting part 4 can slide relative to the column 1. The distance between the quick-installation mounting part 3 and the matching mounting part 4 is determined according to the height of the fence 2 and the position of the quick-installation bolt 6 on the fence 2. When the positions of the quick-installation mounting part 3 and the matching mounting part 4 are determined, the screw is matched with the threaded hole 5 so that the screw passes through the threaded hole 5 and is in close contact with the column 1, so that the quick-installation mounting part 3 and the matching mounting part 4 are fixed relative to the column 1.

[0047] The fence 2 includes an outer frame 201 and a mesh surface 202, the mesh surface 202 is fixed on the outer frame 201, the quick-install bolts 6 are fixedly installed with the outer frame 201, the screw rods 601 pass through the through holes provided on the outer frame 201, and the outer frame 201 is fixed between the blocking portion 603 and the nut 602 by the nut 602;

[0048] Then the fence 2 fixed with the quick-install bolts 6 is obliquely inserted into the limiting groove 403. Figure 8 The fence 2 is installed in the manner shown, and then the fence 2 is rotated around the quick-release bolt 6 located in the limiting groove 403, so that the fence 2 is rotated to be parallel to the column 1. Through the provided baffle 402, after the fence 2 is rotated to be parallel to the column 1, an additional function of limiting the outer frame 201 is obtained. In the process of rotating the fence 2 to be parallel to the column 1, the engaging portion 604 in the quick-release bolt 6 to be matched with the quick-release mounting member 3 will pass through the groove 305 into the gap between the first fixed frame 301 and the inner plate 303, and then the engaging portion 604 will push the lower arm 3071 of the movable clamp 307 to rotate the movable clamp 307 around the rotating shaft 306. In the process of the rotation of the movable clamp 307, the limiting portion 3073 of the movable clamp 307 will push the abutment plate 3012 to rotate around one of the fastening bolts 302, as shown in FIG. Figure 3 As shown, the fastening bolt 302 penetrates and is fixed in the gap between the inner plate 303 and the first fixing frame 301, and the threaded portion of the fastening bolt 302 is threadedly connected to the inner plate 303. The portion of the fastening bolt 302 located in the gap is a smooth portion, that is, a portion without a thread. When the abutment plate 3012 rotates, it will overcome the elastic force of the second torsion spring 3015. Similarly, when the movable clamp 307 rotates, it will overcome the elastic force of the first torsion spring 3010. Figure 6 The illustrated position is used for explanation. When the movable clamp 307 rotates so that the limiting portion 3073 is located above the abutment plate 3012, the elastic force of the second torsion spring 3015 pushes the abutment plate 3012 to rotate in the opposite direction, so that one corner of the abutment plate 3012 abuts against the lower outer surface of the limiting portion 3073, thereby preventing the movable clamp 307 from rotating counterclockwise around the rotating shaft 306. At this time, the limiting arm 3072 of the movable clamp 307 cooperates with the straight groove 304 to limit and fix the abutment portion 603, thereby realizing the rapid fixed installation of the fence 2.

[0049] Since the fence 2 can be placed in the limiting groove 403 through the screw rod 601 when installing the fence 2, a certain support can be provided for the fence 2, thereby reducing the force required for the subsequent installation of the fence 2. In the subsequent installation of the fence 2, it is only necessary to rotate the fence 2 so that the fence 2 is parallel to the column 1. The installation is simple, labor-saving and fast, and the structure of the fence 2 after installation is stable. When the fence 2 needs to be disassembled, it is only necessary to disassemble the support plate 3012 and rotate the fastening bolt 302 to realize the disassembly of the fence 2. Fig. 9The position shown is explained, when the support plate 3012 is disassembled and the fastening bolt 302 is rotated, the support plate 3012 can only rotate around the third limiting axis 3013, and under the elastic force of the first torsion spring 3010, the movable clamp 307 will rotate counterclockwise, and when the movable clamp 307 rotates counterclockwise, the limiting portion 3073 of the movable clamp 307 will squeeze the upper right corner of the support plate 3012, so that the support plate 3012 rotates clockwise around the third limiting axis 3013, so that the limiting arm 3072 of the movable clamp 307 no longer blocks the movement of the limiting portion 605, and the rapid disassembly of the purse seine 2 can be completed according to the above-mentioned installation principle;

[0050] It should be noted that the rotating axis 306, the first limiting axis 308, the first torsion spring fixed axis 309, the second limiting axis 3011, the third limiting axis 3013, the second torsion spring fixed axis 3014, and the fourth limiting bearing 3016 are respectively fixedly connected to the first fixed frame 301 and / or the inner plate 303 on the surface adjacent to the inner plate 303 and the first fixed frame 301.

[0051] The fence according to the embodiment of the present invention includes the fence quick disassembly and assembly device according to the above embodiment. Since the fence quick disassembly and assembly device according to the above embodiment of the present invention has the above-mentioned quick disassembly effect, the fence according to the embodiment of the present invention installed with the fence quick disassembly and assembly device also has the corresponding technical effect, that is, the fence 2 can be quickly installed, which can save time and effort and has the advantages of quick installation.

[0052] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
