Description

Technical Field

[0001] This utility model relates to the field of police equipment technology, and in particular to a foldable enclosure that can be stored in a box. Background Technology

[0002] The hoarding, consisting of hoarding frames and hoarding fabric, is widely applicable to various fields where temporary shelter is urgently needed, such as police investigation sites, temporary shelter operations in various public places, and outdoor shelter for residential users, to achieve temporary isolation and blockage of the corresponding area. It can also be combined into enclosed and semi-enclosed spaces of varying sizes according to the needs of the site.

[0003] Existing fencing supports, when folded, are either placed randomly, which can lead to dust accumulation or rusting of metal parts if left idle for a long time, or they are stored in separate boxes or bags. When the fencing supports are unfolded for use, the boxes or bags need to be folded up and placed aside, which is inconvenient for police officers to store when they are on duty.

[0004] In fact, there are many types of connecting joints for existing fencing supports. For example, the portable folding fencing for police disclosed in patent number CN115898135A has a hinge-like structure at the straight connection point. In the unfolded state, there is a large gap between the two rods, which not only affects the overall aesthetics but also causes great stress on the connecting joint. Another example is the folding mechanism disclosed in patent number CN202323422108.3, which includes a base and two folding parts. The maximum flipping angle of each folding part is 90°. If the two rods need to be folded parallel, two folding parts are required. The base also needs to be equipped with two mating structures to cooperate with the two folding parts respectively. Therefore, the number of parts in the folding mechanism increases, making operation inconvenient. Moreover, if the base is held while folding, there is a risk of pinching the hand. This problem also exists in patent number CN115898135A.

[0005] Therefore, it is necessary to design a foldable enclosure that can be stored into a box and effectively utilized when in use. Utility Model Content

[0006] In order to solve the technical problems of existing foldable barriers that can be stored in boxes, which cannot be effectively stored or the boxes used for storage cannot be effectively used during duty, this utility model provides a foldable barrier that can be stored in boxes to solve the above problems.

[0007] This utility model proposes a foldable enclosure that can be stored in a box, including a box body, an enclosure support, and an enclosure fabric. The box body is formed by an upper box and a lower box that are closed together, and the upper box and the lower box have interlocking locking assemblies. The enclosure support includes at least two vertical rods and a horizontal rod connecting the vertical rods. The inner bottom surface of both the upper box and the lower box has a first support base for mounting a vertical rod. The vertical rods and the horizontal rods can be disassembled or folded and placed inside the box body. The enclosure fabric is connected to the enclosure support.

[0008] In an optional embodiment of this utility model, each of the vertical and horizontal bars includes one or more rod bodies and a support joint connecting adjacent rod bodies. The support joint includes a first connector and a second connector rotatably connected by a first rotating shaft.

The self-locking female head and the self-locking male head can be engaged to lock or disengaged to unlock. The first rotating shaft is offset from the first connector and the second connector along the vertical length direction of the rod body.

[0009] When the self-locking female and self-locking male are in the locked state, the first connector and the second connector unfold into a straight line, and the first pivot is located on the same side of the first connector and the second connector. When the self-locking female and self-locking male are in the unlocked state, the first connector and the second connector can rotate 180° relative to each other. At this time, the first pivot is located between the two opposite sides of the first connector and the second connector.

[0010] In an optional embodiment of this utility model, the self-locking female connector includes a base, a limiting post, a limiting head, and a return spring. The base is fixed to the first connecting member, the limiting head is fixed to one end of the limiting post, the return spring is sleeved outside the limiting post, the limiting head and the return spring respectively abut against both sides of the base, the limiting post passes through the base, and the return spring is pressed between the base and the limiting post. The self-locking male connector has a limiting hole for the end of the limiting post to be inserted, so that the self-locking female connector and the self-locking male connector can be engaged and locked.

[0011] In an optional embodiment of this utility model, the base includes an outer plate and an inner plate connected to the outer plate and located inside the self-locking female head. The limiting head and the return spring are located on both sides of the outer plate, and the return spring is located between the outer plate and the inner plate. The self-locking male head includes a fixedly installed limiting plate, and the limiting hole is located on the limiting plate. A baffle is connected to one end of the limiting plate facing the second mounting base. When the self-locking female head and the self-locking male head are engaged and locked, the two ends of the outer plate abut against the end faces of the two rods respectively, and the baffle abuts against the end face of the inner plate.

[0012] In an optional embodiment of this utility model, the end of the limiting plate away from the second mounting base is connected to a guide plate, and a chamfer is provided at the connection between the limiting plate and the guide plate. The end of the limiting post that mates with the limiting hole has an arc-shaped surface extending toward the side of the second connector.

[0013] In an optional embodiment of this utility model, a right-angle joint is provided at the connection between the vertical bar and the horizontal bar; the right-angle joint includes two back plates that are rotatably connected, the two back plates are at a right angle when unfolded, and are stacked in parallel when folded.

[0014] In an optional embodiment of this utility model, one end of one back plate has an arc-shaped connector and a second rotating shaft fixed inside the arc-shaped connector. The outer surface of the arc-shaped connector has a concave arc-shaped guide groove. The end of the other back plate has an arc-shaped mating surface that mates with the arc-shaped connector and a first limiting block and a second limiting block located at both ends of the arc-shaped mating surface. The first limiting block moves within the arc-shaped guide groove. When the right-angle joint is in the unfolded state, the second limiting block abuts against the end of the arc-shaped connector. The first limiting block is located at one end of the arc-shaped guide groove. When the right-angle joint is in the folded state, the first limiting block is located at the other end of the arc-shaped guide groove.

[0015] In an optional embodiment of this utility model, three or more vertical rods are provided, and a second support base is detachably connected to the lower end of the middle vertical rod. The second support base is fixed by a pin inserted into the ground.

[0016] In an optional embodiment of this utility model, a hanging ring is also fixed to the upper end of the vertical rod. The hanging ring is connected to one end of the pull rope through a rope buckle, and the other end of the pull rope is fixed to the ground through a pin.

[0017] In an optional embodiment of this utility model, the locking assembly includes a locking hook and a locking body. The locking hook is located on the outer surface of the upper box; the locking body is located on the outer surface of the lower box. The locking body includes a fixed plate, a third rotating shaft, a fourth rotating shaft, a fifth rotating shaft, a locking ring, a limiting frame, an operating plate, and a locking plate. The third rotating shaft is fixed to the fixed plate. The limiting frame and the operating plate are rotatably connected to the third and fourth rotating shafts. The third, fourth, and fifth rotating shafts are arranged in parallel from top to bottom. The locking plate rotates with the fifth rotating shaft. The locking ring is connected to a fifth rotating shaft, which is equipped with a torsion spring that engages with the locking plate. The locking plate rotates within the limited space between the limiting frame and the operating plate. One end of the locking ring is a limiting shaft, and the other end is an abutment plate that extends into the limiting frame. A compression spring connects the abutment plate and the limiting frame. The lower end of the abutment plate abuts against the fourth rotating shaft. When the locking assembly is engaged, the limiting shaft hooks onto the locking hook, and the locking plate engages with the operating plate and the fixed plate under the action of the torsion spring. When the locking plate rotates towards the limiting frame, the locking plate separates from the operating plate and the fixed plate, and the locking assembly can be unlocked.

[0018] The beneficial effects of this utility model are:

[0019] (1) The foldable enclosure described in this utility model can be stored in a box. The upper and lower boxes that can be separated are connected by a locking assembly to form a box body. A first support seat for installing a vertical rod is provided on the inner bottom surface of both the upper and lower boxes. When the foldable enclosure is used, the box body can be used as the bottom plate of the foldable enclosure and does not need to be idle for storage. After use, the enclosure bracket can also be stored in the box body to avoid dust accumulation or damage to parts.

[0020] (2) The support joint in this utility model is formed by connecting two connectors. By reasonably arranging the position of the first rotating shaft, the two connectors can rotate 180° relative to each other. The structure is simple and easy to operate. At the same time, the two connectors also have mounting seats inserted into the rod body. Compared with traditional connecting joints, the connection strength is higher.

[0021] (3) The self-locking female head in this utility model uses the elastic force of the reset spring to achieve self-locking, and improves the locking effect by limiting the end face.

[0022] (4) This utility model uses the combination of the arc-shaped surface on the limiting post and the chamfer at the end of the limiting plate to make the foldable enclosure that can be stored into a box directly straightened and unfolded without the need to lift the limiting head, thus improving the unfolding speed.

[0045] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0046] Example 1

[0047] like Figure 1 , Figure 5 , Figure 15 and Figure 20As shown, a foldable enclosure that can be stored in a box includes a box body 13, an enclosure support 14, and an enclosure fabric 15. The box body 13 is formed by an upper box 1301 and a lower box 1302 covering each other. The upper box 1301 and the lower box 1302 have interlocking locking assemblies 20. The enclosure support 14 includes at least two vertical rods 16 and a horizontal rod 17 connecting the vertical rods 16. The inner bottom surfaces of the upper box 1301 and the lower box 1302 each have a first support seat 10 for mounting a vertical rod 16. The vertical rods 16 and the horizontal rods 17 can be disassembled or folded and placed inside the box body 13. When the locking assembly 20 is unlocked, the upper box 1301 and the lower box 1302 can be separated. At this time, the upper box 1301 and the lower box 1302 can serve as the base of the vertical rods 16 at both ends when the folding support is raised. The enclosure fabric 15 is connected to the enclosure support 14 and is used to form a screen wall covering.

[0048] The box body 13 can be a regular cuboid structure. The cross-sectional shape of the vertical rod 16 and the horizontal rod 17 can be circular, rectangular, or other shapes. In the specific embodiment of this utility model, the cross-sectional shape of the vertical rod 16 and the horizontal rod 17 is rectangular. Since the sides of the vertical rod 16 and the horizontal rod 17 are flat, when the enclosure bracket 14 is folded, it can be placed stably inside the box body 13 without the need for a limiting structure inside the box body 13. Figure 20 As shown.

[0049] Each vertical rod 16 and horizontal rod 17 can be formed by connecting multiple rods 12. The rods 12 inside the vertical rod 16 and horizontal rod 17, as well as the vertical rod 16 and horizontal rod 17, can be connected by detachable connection methods such as bolt connection or hinge connection, or by foldable storage methods such as telescopic structure or folding mechanism disclosed in patent number CN202323422108.3, so that the vertical rod 16 and horizontal rod 17 can be placed in the box 13 after being retracted, and can be supported to form a enclosure when unfolded. The connection structure inside the vertical rod 16 and horizontal rod 17 can unfold the two rods 12 into a straight line, and the connection structure between the vertical rod 16 and horizontal rod 17 can unfold the two vertical rods 16 and horizontal rod 17 into a right angle.

[0050] First support seat 10:

[0051] like Figure 3 As shown, the first support base 10 may include a base plate 1001, a sleeve 1002 fitted onto the lower end of the vertical rod 16, and a spring pin 1003 connecting the sleeve 1002 and the vertical rod 16. The base plate 1001 is fixed to the sleeve 1002, but not fixed to the upper box 1301 or the lower box 1302. When supporting the enclosure bracket 14, the sleeves 1002 inside the upper box 1301 and the lower box 1302 need to be arranged on the same plane. When folded for storage, the sleeves 1002 inside the upper box 1301 and the lower box 1302 can be shifted to avoid interference when closing. Figure 20 As shown, the two first support seats 10 are staggered.

[0052] In this embodiment, there is one horizontal bar 17 and two vertical bars 16. The enclosure bracket 14 is supported by the two vertical bars 16.

[0053] Support joint 11:

[0054] In this embodiment, adjacent rods 12 are connected by a bracket joint 11 inside the vertical rod 16 and the horizontal rod 17, such as... Figure 4 , Figures 7-12 As shown, the support joint 11 includes a first connector 2 and a second connector 3 rotatably connected by a first rotating shaft 1. The first connector 2 includes a self-locking female head 4 and a first mounting seat 5 fixedly connected. The second connector 3 includes a self-locking male head 6 and a second mounting seat 7 fixedly connected. The first mounting seat 5 and the second mounting seat 7 are respectively inserted into two adjacent rods 12 and fixed thereto. The self-locking female head 4 and the self-locking male head 6 can be engaged to lock or disengaged to unlock. The first rotating shaft 1 is offset from the first connector 2 and the second connector 3 along the length direction perpendicular to the rod 12.

[0055] When the self-locking female head 4 and the self-locking male head 6 are in the locked state, the first connecting piece 2 and the second connecting piece 3 are unfolded into a straight line, and the first rotating shaft 1 is located on the same side of the first connecting piece 2 and the second connecting piece 3. When the self-locking female head 4 and the self-locking male head 6 are in the unlocked state, the first connecting piece 2 and the second connecting piece 3 can be rotated 180° relative to each other. At this time, the first rotating shaft 1 is located between the two opposite sides of the first connecting piece 2 and the second connecting piece 3.

[0056] In traditional connecting joints, the rotation angle of the connecting parts is limited because the first rotating shaft 1 is located in the middle of the two connecting parts. This invention sets the first rotating shaft 1 offset from the two connecting parts, such as... Figure 6 In the unfolded state shown, the first pivot 1 is located below the first connector 2 and the second connector 3. Assuming the first connector 2 is fixed, when the second connector 3 is rotated, since the structures of the first connector 2 and the second connector 3 do not interfere with each other, the second connector 3 can rotate 180° around the first pivot 1, causing the two rods 12 to fold in parallel. The self-locking male head 6 and the self-locking female head 4 in this invention are used to lock the enclosure bracket 14 in the unfolded state, so that the two rods 12 form a stable straight rod. Secondly, the first mounting base 5 and the second mounting base 7 in this invention can be inserted into the rods 12. Compared with the traditional structure that only installs hinges on the outside of the rods 12, since the first mounting base 5 and the second mounting base 7 are separate fixed parts, and the rotating part is located at the first pivot 1 outside the rods 12, the first mounting base 5 and the second mounting base 7 can be provided with multiple fixing surfaces to improve the connection strength.

[0057] In terms of operation, this utility model consists of two relatively moving parts. After the bracket joint 11 is mounted on the enclosure bracket 14, when folding is required, one of the connecting parts can be fixed, and only the rod 12 connected to the other connecting part needs to be rotated. Compared with the structure in patent number CN202323422108.3 that requires rotating two folding parts, this utility model is more convenient to operate, the connection structure is simplified, and there is no risk of pinching hands.

[0058] The self-locking female connector 4 and the self-locking male connector 6 are mating parts that can automatically lock without external force, such as interlocking hooks or pins. They can also be purchased commercially. The structure of the self-locking female connector 4 and the self-locking male connector 6 shown in the attached drawings of this utility model is as follows:

[0059] The self-locking female connector 4 includes a base 401, a limiting post 402, a limiting head 403, and a return spring 404. The base 401 is fixed to the first connecting member 2. The limiting head 403 is fixed to one end of the limiting post 402. The return spring 404 is sleeved on the outside of the limiting post 402. The limiting head 403 and the return spring 404 abut against the two sides of the base 401 respectively. The limiting post 402 passes through the base 401, and the return spring 404 is pressed between the base 401 and the limiting post 402. The self-locking male connector 6 has a limiting hole 601 for inserting the end of the limiting post 402 so that the self-locking female connector 4 and the self-locking male connector 6 can be engaged and locked. The base 401 is a fixed component, serving as the mounting base for other moving components. The base 401 also limits the positioning of the limiting head 403 and the return spring 404. In the free state, the return spring 404 presses against the limiting post 402, causing the limiting post 402 to insert into the limiting hole 601. When the limiting head 403 is pulled up, the limiting post 402 is also lifted and moves away from the limiting hole 601. The limiting post 402 drives one end of the return spring 404 to move, while the other end of the return spring 404 is further compressed due to the restriction of the base 401, storing energy for the reset of the limiting post 402.

[0060] like Figures 9-11As shown, the limiting head 403 and the return spring 404 are located on the upper and lower sides of the base 401. The limiting head 403 is exposed to the outside, making it convenient for the user to lift the limiting head 403. The limiting post 402 passes through the base 401, while the return spring 404 and the limiting post 402 are hidden downward inside the first connecting member 2. The lower end of the limiting post 402 has a first protrusion 4021. The upper end of the return spring 404 abuts against the lower surface of the base 401, and the lower end abuts against the upper surface of the first protrusion 4021. When the limiting head 403 is lifted upward, the first protrusion 4021 of the limiting post 402 will pass through the lower surface of the base 401 and drive the return spring 404 to move upward. When the limiting head 403 is released, the return spring 404 drives the limiting post 402 to return downward until the limiting head 403 abuts against the upper surface of the base 401. Alternatively, a second protrusion 4024 can be provided on the limiting post 402 below the first protrusion 4021. The second protrusion 4024 cannot pass through the lower surface of the base 401. When the limiting post 402 moves upward, the second protrusion 4024 can serve as the ultimate limit of the limiting post 402.

[0061] The base 401 can be a single panel. In this embodiment, to ensure a smoother connection between adjacent rods 12, the base 401 includes an outer plate 4011 and an inner plate 4012 connected to the outer plate 4011 and located inside the self-locking female head 4. The limiting head 403 and the return spring 404 are located on both sides of the outer plate 4011, and the return spring 404 is located between the outer plate 4011 and the inner plate 4012. The self-locking male head 6 includes a fixedly installed limiting plate 602. The limiting hole 601 is located on the limiting plate 602. A baffle 603 is connected to one end of the limiting plate 602 facing the second mounting base 7. When the self-locking female head 4 and the self-locking male head 6 are engaged and locked, the two ends of the outer plate 4011 abut against the end faces of the two rods 12 respectively, and the baffle 603 abuts against the end face of the inner plate 4012.

[0062] like Figure 7 and Figure 10 As shown, the outer plate 4011 surrounds the self-locking nut 4 and can be composed of multiple panels. In this embodiment, the outer plate 4011 is formed by three panels connected in sequence. It can connect with the end faces of the two rods 12 in the unfolded state, avoiding gaps between the rods 12. This not only improves the appearance integrity but also provides support through the abutment of the end faces, reducing the stress on the locking part of the bracket joint 11. Figure 10 As shown, the middle panel of the outer plate 4011 is located above the inner plate 4012. The inner plate 4012 is used to limit the lower end of the return spring 404. The limiting plate 602 is located below the inner plate 4012. The limiting post 402 can be inserted into the limiting hole 601 after passing through the inner plate 4012. The inner plate 4012 is used to abut against the baffle 603, which plays the role of limiting the extreme position of the unfolded position.

[0063] The limiting post 402 is arranged perpendicular to the length direction of the rod 12 and penetrates the base 401. Therefore, the base 401 is parallel to the length direction of the rod 12 and can fill the space between adjacent rods 12. A limiting plate 602 is fixed on the second connecting member 3. The limiting plate 602 and the base 401 are arranged parallel to each other, and the limiting hole 601 is located on the limiting plate 602. Figure 9 As shown, the limiting post 402 is inserted vertically downward into the limiting hole 601.

[0064] The structures of the first mounting base 5 and the second mounting base 7 are similar:

[0065] Both the first mounting base 5 and the second mounting base 7 include one or more mounting plates 8 that are fitted against and fixed to the inner surface of the rod 12, and a connecting plate 9 connecting the mounting plates 8. The mounting plates 8 are fitted against the inner surface of the rod 12, which serves both a positioning function and increases the contact surface and improves the connection strength. The connecting plate 9 is used to ensure the stability of the first mounting base 5 and the second mounting base 7.

[0066] This invention can be used to connect rods 12 with circular, rectangular or other arbitrary cross-sections, as long as two mounting bases are designed according to the cross-sectional shape of the rod 12.

[0067] This embodiment uses a rod 12 with a rectangular cross-section as an example to describe the structure of the first mounting base 5 and the second mounting base 7, as follows: Figure 7 and Figure 8 As shown, both the first mounting base 5 and the second mounting base 7 include two mounting plates 8 arranged in parallel, and the connecting plate 9 is arranged perpendicularly to the mounting plates 8. The middle panel of the outer plate 4011 in the self-locking nut 4 is perpendicular to the mounting plate 8, and the other two panels of the outer plate 4011 are parallel to the two mounting plates 8 of the first mounting base 5.

[0068] Right-angle joint 19:

[0069] In this embodiment, adjacent rods 12 are connected by a bracket joint 11 inside the vertical rod 16 and the horizontal rod 17. The right-angle joint 19 includes two rotatably connected back plates 1901. The two back plates 1901 are fixed to the vertical rod 16 and the horizontal rod 17 respectively. The two back plates 1901 are at right angles when unfolded and are parallel to each other when folded. The specific structure is as follows:

[0070] One of the back plates 1901 has an arc-shaped connector 1902 at one end and a second rotating shaft 1903 fixed inside the arc-shaped connector 1902. The outer surface of the arc-shaped connector 1902 has a concave arc-shaped guide groove 1904. The other back plate 1901 has an arc-shaped mating surface 1905 that mates with the arc-shaped connector 1902 at one end, and a first limiting block 1906 and a second limiting block 1907 located at both ends of the arc-shaped mating surface 1905. The first limiting block 1906 moves within the arc-shaped guide groove 1904. When the right-angle joint 19 is in the unfolded state, the second limiting block 1907 abuts against the end of the arc-shaped connector 1902. The first limiting block 1906 is located at one end of the arc-shaped guide groove 1904. When the right-angle joint 19 is in the folded state, the first limiting block 1906 is located at the other end of the arc-shaped guide groove 1904.

[0071] like Figure 13 and Figure 14 As shown, the first limiting block 1906 moves within the arc-shaped guide groove 1904. The arc of the arc-shaped guide groove 1904 is the maximum unfolding angle of the two right-angle joints 19. The second limiting block 1907 and the first limiting block 1906 together surround the arc-shaped connector 1902 to prevent the two back plates 1901 from detaching from the second rotating shaft 1903. The second limiting block 1907 can be connected to the second rotating shaft 1903 through an anti-detachment structure, as long as the second limiting block 1907 can rotate around the second rotating shaft 1903. Alternatively, limiting shoulders 1908 can be set at both ends of the second rotating shaft 1903 so that the back plates 1901 containing the first limiting block 1906 and the second limiting block 1907 can only rotate around the second rotating shaft 1903 and cannot detach.

[0072] Locking assembly 20:

[0073] The locking assembly 20 can use the lock structure found on suitcases in the prior art. The structure of the locking assembly 20 used in this embodiment is as follows:

[0074] like Figure 16 and Figure 17As shown, the device includes a locking hook 21 and a locking body 22. The locking hook 21 is located on the outer surface of the upper box 1301; the locking body 22 is located on the outer surface of the lower box 1302. The locking body 22 includes a fixing plate 2201, a third rotating shaft 2202, a fourth rotating shaft 2203, a fifth rotating shaft 2204, a locking ring 2205, a limiting frame 2206, an operating plate 2207, and a locking plate 2208. The fixing plate 2201 is fixed to the outer surface of the lower box 1302. The third rotating shaft 2202 is fixed to the fixing plate 2201. The limiting frame 2206 and the operating plate 2207 are rotatably connected to the third rotating shaft 2202 and the fourth rotating shaft 2203. The third rotating shaft 2202, the fourth rotating shaft 2203, and the fifth rotating shaft 2204 are arranged in parallel from top to bottom. The locking plate 2208 is rotatably connected to the fifth rotating shaft 2204. A torsion spring 2210 is provided on 204 to engage the locking plate 2208, and the locking plate 2208 rotates within the limiting space 2211 between the limiting frame 2206 and the operating plate 2207. One end of the locking ring 2205 is a limiting shaft 22051, and the other end is an abutment plate 22052 that extends into the limiting frame 2206. A compression spring 2209 is connected between the abutment plate 22052 and the limiting frame 2206. The lower end of the abutment plate 22052 abuts against the fourth rotating shaft 2203. When the latch assembly 20 is engaged, the limiting shaft 22051 hooks onto the locking hook 21, and the locking plate 2208 engages with the limiting plate and the fixing plate 2201 under the action of the torsion spring 2210. When the locking plate 2208 rotates toward the limiting frame 2206, the locking plate 2208 separates from the limiting plate and the fixing plate 2201, and the latch assembly 20 can be unlocked.

[0075] The third rotating shaft 2202 is a fixed shaft, while the fourth rotating shaft 2203 and the fifth rotating shaft 2204 are movable shafts. The limiting frame 2206 is a frame-shaped structure with an internal cavity. The locking ring 2205 can extend into the cavity of the limiting frame 2206, which can limit the locking ring 2205 and prevent it from shaking. The compression spring 2209 presses the locking ring 2205 downward when it is hooked on the locking hook 21. The fourth rotating shaft 2203 abuts against the lower end of the abutment plate 22052, which can support the locking ring 2205, allowing it to move up and down under the drive of the fourth rotating shaft 2203 without manual pulling.

[0076] like Figure 18 and Figure 19As shown, there is a through hole between the limiting frame 2206 and the operating plate 2207 to form a limiting space 2211. One end of the locking plate 2208 is an operating part 22082 that passes through the through hole, and the other end is a raised bent part 22081. In the fastened state, the torsion spring 2210 presses against the bent part 22081 from below, so that the bent part 22081 is subjected to an upward force. The bent part 22081 hooks onto the fixing plate 2201, while the operating part 22082 is subjected to a downward force, pressing the operating plate 2207 and preventing the operating plate 2207 from moving upward. When it is necessary to open the latch assembly 20, the operating part 22082 is pulled upward. At this time, the operating plate 2207 can rotate upward around the third rotating shaft 2202. At the same time, the fourth rotating shaft 2203, the fifth rotating shaft 2204 and the limiting frame 2206 connected to the operating plate 2207 will also rotate around the third rotating shaft 2202, thereby generating an upward displacement. The abutment plate 22052, which is abutted by the fourth rotating shaft 2203, also generates an upward displacement, thereby causing the limiting shaft 22051, which is fixedly connected to the abutment plate 22052, to disengage upward from the latch 21.

[0077] Using the locking assembly 20 of this embodiment, it can be locked by pressing and unlocked by moving the operating part 22082. The operation is simple and quick, the locking effect is good, and the installation method is also simple, as it can be directly fixed to the outer surface of the box 13.

[0078] Example 2

[0079] In the above embodiment, when the limiting post 402 is inserted into the limiting hole 601, the self-locking male head 6 and the self-locking female head 4 are locked. When unlocking or entering the locked state from the unlocked state is required, the limiting head 403 must be pulled outward to make the limiting post 402 leave the limiting hole 601, allowing the second connecting member 3 to rotate. However, when unfolding the bracket joint 11, one hand needs to hold the first connecting member 2, and the other hand needs to straighten the second connecting member 3, making it impossible to pull the limiting head 403. Therefore, it is difficult for one person to operate. For this reason, the following improvement is made in this embodiment:

[0080] A guide plate 604 is connected to the end of the limiting plate away from the second mounting base 7. A chamfer 605 is provided at the connection between the limiting plate and the guide plate 604. The end of the limiting post 402 that mates with the limiting hole 601 has an arc-shaped surface 4022 extending toward the side of the second connecting member 3. Figure 9 and Figure 11As shown, the second connector 3 is located to the right of the first connector 2, the arc surface 4022 is located to the bottom right of the limiting post 402, and the chamfer 605 is located at the left end of the limiting plate. When the second connector 3 is folded, the self-locking male head 6 disengages from the first connector 2 to the right. When the second connector 3 needs to be unfolded, the second connector 3 is rotated counterclockwise around the first pivot 1, and the self-locking male head 6 gradually enters the self-locking female head 4. The chamfer 605 first contacts the arc surface 4022. Under the arc guidance of the two, the limiting plate can squeeze the limiting post 402, causing the limiting post 402 to move upward until the limiting plate reaches the horizontal position. At this time, the limiting post 402 enters the limiting hole 601.

[0081] With the improvement of this embodiment, when unfolding the support joint 11, it is only necessary to directly rotate and straighten the rod 12 connecting the two connectors, without having to pull up the limiting head 403, and it can be operated by a single person.

[0082] Example 3

[0083] Based on Embodiment 2, to enhance the locking effect when the support joint 11 is deployed, this embodiment further improves as follows: One end of the limiting post 402 that mates with the limiting hole 601 has a limiting plane 4023 arranged opposite to the arc-shaped surface 4022. When the self-locking female head 4 and the self-locking male head 6 are engaged and locked, the limiting plane 4023 abuts against the inner surface of the limiting hole 601. For example... Figure 9 and Figure 11 As shown, the baffle 603 is used to prevent the second connector 3 from rotating excessively counterclockwise when unfolded, and the fit between the limiting plane 4023 and the inner surface of the limiting hole 601 is used to ensure that the two rods 12 are in a stable and straight state, and to prevent the second connector 3 from deforming in the clockwise folded state.

[0084] Example 4

[0085] The difference between this embodiment and the previous embodiment is that three or more vertical rods 16 are provided, and the lower end of the middle vertical rod 16 is detachably connected to a second support 23. The second support 23 is fixed by a pin 24 inserted into the ground. The structure of the second support 23 is the same as that of the first support 10. When the enclosure bracket 14 is retracted, the second support 23 can be placed inside the box 13.

[0086] In this embodiment, the area of ​​the folding fence can be infinitely extended. Each horizontal bar 17 is connected to a vertical bar 16 at both ends. When multiple horizontal bars 17 are set, the vertical bar 16 in the middle is fixed by the second support seat 23, and the vertical bars 16 at both ends are fixed by the first support seat 10 inside the box body 13.

[0087] When the horizontal bar 17 and the vertical bar 16 are connected by a right-angle joint 19, since the rotation angle of the right-angle joint 19 is 90°, the vertical bar 16 can only be folded with one side of the horizontal bar 17. If one vertical bar 16 is connected to two horizontal bars 17 at the same time, folding cannot be achieved. Therefore, two vertical bars 16 are arranged side by side between two adjacent horizontal bars 17 via hinges. Figure 2 As shown, the two vertical rods 16 are connected to the two horizontal rods 17 via right-angle joints 19. When folding is required, the hinges of the two vertical rods 16 are removed, and the vertical rods 16 can be folded separately with their respective connected horizontal rods 17, as shown. Figure 20 As shown.

[0088] Example 5

[0089] Based on the above embodiments, such as Figure 2 As shown, a hanging ring 25 is also fixed to the upper end of the vertical rod 16. The hanging ring 25 is connected to one end of the pull rope 18 through a rope buckle 26, and the other end of the pull rope 18 is fixed to the ground through a pin 24.

[0090] In harsh environments, such as strong winds and heavy rain, it is necessary to enhance the stability of the folding fence. Pulling the rope 18 along a plane perpendicular to the plane of the fence cloth 15 can prevent the folding fence from tilting or overturning.
