DETAILED DESCRIPTION

[0027] like Figure 1-10As shown, a portable foldable enclosure includes a barrier cloth 1, a first main pole 2, a second main pole 3, and a plurality of first connecting rods 4, one end of all the first connecting rods 4 are rotatably connected to one end of the first main pole 2 and are distributed around the first main pole 2, a connecting head 5 that cooperates with the other end of the first connecting rod 4 is provided on the edge of the barrier cloth 1, a first rotation angle controller is provided between the two ends of the first main pole 2, an execution end of the first rotation angle controller is connected between the two ends of the first connecting rod 4, the other end of the first main pole 2 is connected to one end of the second main pole 3 through the second rotation angle controller, and a gripper is provided at the other end of the second main pole 3.

[0028] In the present embodiment, the connecting head 5 on the cloth blocking 1 (the connecting head 5 is a cylindrical object with an open end, and the circumferential surface of the cylindrical object is fixedly connected to the cloth blocking 1. When the cloth blocking 1 is connected to the first connecting rod 4, it is only necessary to insert the end of the first connecting rod 4 away from the first main rod 2 into the cylindrical object) is fixedly connected to the end of the first connecting rod 4 away from the first main rod 2. Then, when the enclosure needs to be opened (deployed), all the first connecting rods 4 are controlled to rotate to a state perpendicular to the first main rod 2 through the second rotation angle controller. At this time, the cloth blocking 1 is stretched open by all the first connecting rods 4. Then, the second main rod 3 is controlled to rotate to a state where the angle with the first main rod 2 is greater than or equal to 90 degrees through the first rotation angle controller. At this time, the cloth blocking 1 is turned away from the second main rod 3. The side away from the first main pole 2 is placed on the ground. At the same time, the end of the second main pole 3 away from the first main pole 2 is also placed on the ground and fixed to the ground by a grabber. At this time, the end of the second main pole 3 away from the first main pole 2 plays a supporting role, supporting the baffle 1 supported by the first connecting rod 4 to form a surface, so that the baffle 1 is perpendicular to the ground. At this time, the baffle 1 plays the role of a barrier; when the baffle 1 needs to be folded up, all the first connecting rods 4 are controlled by the second rotation angle controller to rotate to be roughly parallel to the first main pole 2, that is to say, all the first connecting rods 4 can be put together with the first main pole 2, and then the second main pole 3 is controlled by the first rotation angle controller to rotate to be together with the first main pole 2, so that the entire enclosure is folded into a column (just like folding an umbrella). In this way, when deploying, it is possible to directly control the rotation of the first connecting rod through the second rotation angle controller so that the angle between the first connecting rod and the first main rod is a right angle, thereby stretching the cloth, and then control the second main rod to rotate to a state roughly parallel to the stretched cloth through the first rotation angle controller, thereby solving the problem that the current enclosure installation and disassembly process is cumbersome and lacks the characteristics of rapid deployment and storage.

[0029] As a preferred approach, there are two ways to design the second rotation angle controller:

[0030] The first design method: the second rotation angle controller includes a first end slot 6, a first end head 7, a first clamping block 8, a first clamping slot 9, and a first spring 10. The first end head 7 is provided at one end of the first main rod 2 away from the first connecting rod 4, and the first end slot 6 that cooperates with the first end head 7 is provided at one end of the second main rod 3. The length line of the first end slot 6 is perpendicular to the second main rod 3 and both ends of the first end slot 6 extend outside the second main rod 3. The first end head 7 is inserted into the first end slot 6. One end of the first rotating shaft 11 is inserted into the first end slot 6 from outside the first end slot 6 and passes through the first end head 7. The first rotating shaft 11 is perpendicular to the first end slot 6 and is perpendicular to the axis of the second main rod 3. A first slot 9 is provided on the second main rod 3. The axis of the first slot 9 is perpendicular to the length line of the second main rod 3 and the first end slot 6. The two ends of one side of the first slot 9 are connected with the bottom of the first end slot 6. The bottom of the first slot 9 is fixedly connected to one end of a first spring 10. The other end of the first spring 10 is fixedly connected to one end of the first clamping block 8. The first clamping block 8 is L-shaped. The end of the L-shaped vertical part of the first clamping block 8 away from the horizontal part faces the opening direction of the first slot 9 and extends out of the second main rod 3. The end of the L-shaped horizontal part of the first clamping block 8 away from the vertical part faces the first end slot 6.

[0031] After such arrangement, the rotation between the first main rod 2 and the second main rod 3 is rotation around the first rotation axis 11. When the first main rod 2 and the second main rod 3 need to be rotated to a preset angle, the user presses the part of the first clamping block 8 located outside the second main rod 3 by hand, so that the L-shaped transverse part of the first clamping block 8 is located outside the first end groove 6, so that the second main rod 3 can be pulled to rotate relative to the first main rod 2. After the second main rod 3 and the first main rod 2 are rotated to a preset angle, the user releases his hand, and the first clamping block 8, under the action of the first spring 10, drives the L-shaped transverse part on the first clamping block 8 to support the first end head 7, thereby limiting the rotation between the first main rod 2 and the second main rod 3.

[0032] The second design method: the second rotation angle controller includes a transition rod 12, a second end head 13, a third end head 14, a second end slot 15, a third end slot 16, a second rotation axis 17, a second clamping slot 18, a third clamping slot 19, a second clamping block 20, a third clamping block 21, a second spring 22, and a third spring 23. The second end slot 15 and the third end head 14 are respectively arranged at both ends of the transition rod 12. The second end head 13 matched with the second end slot 15 is arranged at one end of the first main rod 2 away from the first connecting rod 4. The third end slot 16 matched with the third end head 14 is arranged at one end of the second main rod 3. The second The end slot 15 is rotatably connected to the second end head 13 via a second rotating shaft 17, the third end slot 16 is rotatably connected to the third end head 14 via a third rotating shaft 24, the transition rod 12 is provided with a second slot 18, the second main rod 3 is provided with a third slot 19, one end of the second slot 18 is inside the transition rod 12, and the other end extends out of the transition rod 12, one end of the third slot 19 is inside the second main rod 3, and the other end extends out of the second main rod 3, the length line of the second slot 18 and the length line of the third slot 19 are both perpendicular to the transition rod 12, the length line of the second slot 18 is perpendicular to the length line of the second end slot 15 The length line of the third card slot 19 is perpendicular to the length line of the third end slot 16, the two ends of one side of the second card slot 18 are connected to the root of the second end slot 15, and the two ends of one side of the third card slot 19 are connected to the root of the third end slot 16. One end of the second card slot 18 in the transition rod 12 and one end of the third card slot 19 in the transition rod 12 are respectively connected to one end of the second spring 22 and one end of the third spring 23. One end of the second clamping block 20 extends into the second card slot 18 and is fixedly connected to the other end of the second spring 22. One end of the third clamping block 21 extends into the third card slot 19 is fixedly connected with the other end of the third spring 23, the second clamping block 20 and the third clamping block 21 are both L-shaped, the end of the L-shaped vertical part of the second clamping block 20 away from the horizontal part is toward the opening direction of the second clamping groove 18 and extends to the outside of the transition rod 12, the end of the L-shaped horizontal part of the second clamping block 20 away from the vertical part is toward the second end groove 15, the end of the L-shaped vertical part of the third clamping block 21 away from the horizontal part is toward the opening direction of the third clamping groove 19 and extends to the outside of the second main rod 3, and the end of the L-shaped horizontal part of the third clamping block 21 away from the vertical part is toward the third end groove 16.

[0033] Compared with the first design, the second design has an additional transition rod 12. This design allows the second main rod 3 to be shorter than the first main rod 2, so that the length of the entire enclosure will be shorter after being stored.

[0034] As a preferred mode, the first rotation angle controller includes a plurality of second connecting rods 26, a slider 27, and a stopper. A slider 27 is slidably sleeved between the two ends of the first main rod 2. One end of each second connecting rod 26 is correspondingly connected between the two ends of a first connecting rod 4. The other end of each second connecting rod 26 is rotatably connected to the slider 27. A stopper cooperating with the slider 27 is provided between the two ends of the first main rod 2. After such arrangement, by pushing the slider 27 in the direction of the first connecting rod 4 on the first main rod 2, the angle between the first main rod 2 and the first connecting rod 4 can be enlarged, that is, the enclosure is opened (the enclosure is deployed); by sliding the slider 27 on the first main rod 2 toward the direction of the second main rod 3, the slider 27 drives the second connecting rod 26 to move, thereby making the first connecting rod 4 approach the first main rod 2, that is, making the angle between the first connecting rod 4 and the first main rod 2 smaller, and achieving storage.

[0035] As a preferred embodiment, the limiter includes a first elastic strip 28, a second elastic strip 29, a first through groove 30, and a second through groove 31. The first main rod 2 is a hollow structure. The circumferential surface of the first main rod 2 is respectively provided with a first through groove 30 and a second through groove 31 connected to the interior of the first main rod 2. The first elastic strip 28 and the second elastic strip 29 are arranged in the first main rod 2. A first protrusion 32 is provided between the two ends of the first elastic strip 28. The first protrusion 32 passes through the first through groove 30 and extends out of the first main rod 2. A second protrusion 33 is provided between the two ends of the second elastic strip 29. The second protrusion 33 passes through the second through groove 31 and extends out of the first main rod 2. An elastic block 38 is provided between the two ends of the slider 27. When the elastic block 38 on the slider 27 slides to the second protrusion 33, all the first connecting rods 4 are perpendicular to the first main rod 2. The first protrusion 32 is located on the side of the slider 27 facing the first connecting rod 4.

[0036] After such arrangement, when pushing the slider 27 on the first main rod 2 to move to a position perpendicular to the first connecting rod 4 and the first main rod 2, the user pushes the slider 27 until the elastic block 38 on the slider 27 is lifted by the second protrusion 33, thereby achieving the function of the second protrusion 33 to limit the slider 27. The function of the first protrusion 32 is mainly to prevent the user from pushing the slider 27 too far, causing the slider 27 to hit the first connecting rod 4.

[0037] As a preferred embodiment, the barrier cloth 1 is a rectangular structure, and each of the four corners of the barrier cloth 1 is provided with a connector 5. This design allows one side of the barrier cloth 1 to be substantially seamlessly attached to the ground when deployed.

[0038] As a preferred mode, an extension cloth 34 is provided on the lower edge of the blocking cloth 1. In this way, the extension cloth 14 can be pressed by a heavy object during use, thereby playing the role of fixing the blocking cloth 1 to the ground.

[0039] As a preferred mode, the gripper includes a foot plate 35, a through hole 36, and an insertion rod 37. The upper surface of the foot plate 35 is fixedly connected to the end of the second main rod 3 away from the first main rod 2. The through hole 36 is provided on the foot plate 35 away from the second main rod 3. The outer diameter of the insertion rod 37 is smaller than the inner diameter of the through hole 36. A limiting ring 25 is fixedly provided at one end of the insertion rod 37. The diameter of the limiting ring 25 is larger than the inner diameter of the through hole 36. With such a configuration, when deployed, the insertion rod 37 is inserted into the through hole 36 and then inserted into the ground, so as to achieve the effect of fixing the end of the second main rod 3 away from the first main rod 2 to the ground. When storing, the insertion rod 37 can be pulled out from the ground for storage.

[0040] Preferably, a zipper is provided on the edge of the apron 1, so that multiple apron units can be combined into the apron 1 by means of the zipper.

[0041] Preferably, the blocking cloth 1 is a rectangular structure, and a zipper is provided on the edge of the cloth 1 perpendicular to the third rotation axis 24, so that a plurality of the cloths 1 can be connected to each other to form a cube or a fence.
