Description

Technical Field

[0001] This application belongs to the field of fence manufacturing, specifically a folding fence. Background Technology

[0002] Construction barriers are facilities used to isolate crowds to protect or shield the scene. The barriers need to be relatively large to effectively isolate the crowd and conceal the situation. However, a large barrier inevitably makes it inconvenient to carry; therefore, a foldable barrier that is easy for police to carry is necessary. Utility Model Content

[0003] The purpose of this application is to address the shortcomings of existing technologies by designing a folding fence using a support rod consisting of a rod unit, a female buckle, and a male buckle, in conjunction with a surrounding fabric. This design allows the fence to be stored away when not in use and to be easily unfolded and supported when in use, thus solving the problem that current fences are inconvenient to fold and store for easy portability.

[0004] To achieve the above objectives, the technical solution adopted in this application is: A folding enclosure includes a surrounding fabric, pole units, female snap fasteners, and male snap fasteners. Each pole unit has a male snap fastener at one end and a female snap fastener at the other end. The projections of the male snap fasteners and the female snap fasteners on the end face of the same pole unit are symmetrical about the center of the pole unit. Each pole unit has a first hinge seat on the side facing away from the female snap fastener at the end of the pole unit. One side of the male snap fastener is provided with a second hinge seat that mates with the first hinge seat. The shape of the drape is rectangular. The five rod units are connected in sequence through the first and second hinge seats and can form a support rod by the cooperation of the female snap fastener and the male snap fastener. Each end of the drape is provided with a support rod. Each support rod is parallel to the width line of the drape. The two ends of each rod unit are fixedly connected to the drape through two fixed points. The rotation axes of the first and second hinge seats are parallel to the drape.

[0005] Preferably, the bottom end of the first hinge seat is fixedly connected to the circumferential wall of one end of the rod unit, the actuating end of the first hinge seat is at a predetermined distance from the central axis of the rod unit, and the projection of the actuating end of the first hinge seat on the central axis of the rod unit is away from the rod unit; the bottom end of the second hinge seat is fixedly connected to the circumferential wall of one end of the rod unit, the actuating end of the second hinge seat is at a predetermined distance from the central axis of the rod unit, and the projection of the actuating end of the second hinge seat on the central axis of the rod unit is away from the rod unit.

[0006] Preferably, each of the rod units has a protrusion on the end face corresponding to the first hinge seat, and each of the rod units has a groove on the end face corresponding to the first hinge seat that mates with the protrusion.

[0007] Preferably, the protrusion is a cylinder coaxial with the rod unit, and the groove is a column coaxial with the rod unit.

[0008] Preferably, the snap-fit ​​female head includes a first sleeve, one end of which has an opening that mates with the rod unit, and the other end is closed. The side wall of the first sleeve has an engagement opening near the closed end, and the first hinge seat is provided on the side wall of the first sleeve near the closed end, facing away from the engagement opening.

[0009] Preferably, the male snap fastener includes a second sleeve. One end of the second sleeve has an opening that mates with the rod unit, and the other end is a closed end. A snap-fit ​​plate is rotatably mounted on the side wall of the second sleeve near the closed end. The rotation axis of the snap-fit ​​plate is perpendicular to the axis of the second sleeve. One end of the snap-fit ​​plate has a biting block that mates with the engagement opening. A torsion spring is mounted on the rotation axis that rotatably connects the snap-fit ​​plate and the second sleeve. The two ends of the snap-fit ​​plate are rotatably connected to the side wall of the second sleeve near the closed end. A preset gap exists between the end of the snap-fit ​​plate facing away from the biting block and the second sleeve. When the torsion spring is in its normal state, the biting block is inserted into the engagement opening. When the end of the snap-fit ​​plate facing away from the biting block moves closer to the second sleeve, the torsion spring is twisted and the biting block disengages from the engagement opening.

[0010] Preferably, the projection of the engagement opening onto a plane perpendicular to the rotation axis of the locking plate is a right triangle, with one right-angled side of the right triangle parallel to the axis of the rod unit and facing away from the axis of the rod unit, and the other right-angled side of the right triangle facing the end of the rod unit where the snap-fit ​​female head is disposed.

[0011] Preferably, the covering is made of canvas.

[0012] Preferably, the surrounding fabric is fixedly connected to both ends of the rod unit by rivets.

[0013] Compared with the prior art, this application has the following beneficial effects: This application adopts a support rod consisting of a rod unit, a female buckle head, and a male buckle head, in conjunction with a surrounding cloth, to design a folding fence. This allows the fence to be stored when not in use, and to be easily unfolded and supported when in use, solving the problem that current fences are inconvenient to fold and store for easy carrying.

[0016] like Figure 1-6 As shown, a folding enclosure includes a enclosure fabric 1, rod units 2, female buckles, and male buckles. Each rod unit 2 has a male buckle at one end and a female buckle at the other end. The projections of the male buckles and female buckles on the end face of the same rod unit 2 are symmetrical about the center of the rod unit 2. All rod units 2 with female buckles have a first hinge seat 3 on the side facing away from the female buckle. One side of the male buckle is provided with a second hinge seat 4 that cooperates with the first hinge seat 3. The shape of the drape 1 is rectangular. The five rod units 2 are connected in sequence through the first hinge seat 3 and the second hinge seat 4 and can be formed into a support rod by the cooperation of the female buckle and the male buckle. Each end of the drape 1 is provided with a support rod. Each support rod is parallel to the width line of the drape 1. The two ends of each rod unit 2 are fixedly connected to the drape 1 through two fixed points. The rotation axes of the first hinge seat 3 and the second hinge seat 4 are parallel to the drape 1.

[0017] In this embodiment, the male and female latches are used to fix the two rod units 2 when they are axially connected. The two rod units 2 are hinged together by a first hinge seat 3 and a second hinge seat 4, so that when folding is required, the engagement between the male and female latches is released, and the rod unit 1 can be folded by rotation. Therefore, the first hinge seat 3 is located on the side of the rod unit 2 where the female latch is located, and the side of the first hinge seat 3 facing away from the execution end of the female latch. The two ends of each rod unit 2 are fixedly connected to the surrounding fabric 1 through two fixing points. This way, when folding, since the surrounding fabric 1 is soft, the surrounding fabric 1 will be offset to the outside of the rotation of the two rod bodies 2 when folding, thereby preventing the surrounding fabric 1 from restricting the folding between the two adjacent rod bodies 2.

[0018] As a preferred embodiment, the bottom end of the first hinge seat 3 is fixedly connected to the circumferential wall of one end of the rod unit 2, and the actuating end of the first hinge seat 3 is at a predetermined distance from the central axis of the rod unit 2, which facilitates the rotation of two adjacent rod units 2. The projection of the actuating end of the first hinge seat 3 on the central axis of the rod unit 2 is away from the rod unit 2. The bottom end of the second hinge seat 4 is fixedly connected to the circumferential wall of one end of the rod unit 2, and the actuating end of the second hinge seat 4 is at a predetermined distance from the central axis of the rod unit 2. The projection of the actuating end of the second hinge seat 4 on the central axis of the rod unit 2 is away from the rod unit 2.

[0019] As a preferred embodiment, each rod unit 2 has a protrusion 5 on its end face corresponding to the first hinge seat 3, and each rod unit 2 has a groove 6 on its end face corresponding to the first hinge seat 3 that mates with the protrusion 5. This design prevents radial movement between adjacent rod units 2 after they are assembled into a support rod.

[0020] As a preferred embodiment, the protrusion 5 is a cylinder coaxial with the rod unit 2, and the groove 6 is a columnar shape coaxial with the rod unit 2. The circular design facilitates the machining of the protrusion 5 and the groove 6.

[0021] As a preferred embodiment, the snap-fit ​​female head includes a first sleeve 7, one end of which is provided with an opening that mates with the rod unit 2, and the other end is closed. A meshing opening 8 is provided on the side wall of the first sleeve 7 near the closed end, and a first hinge seat 3 is provided on the side wall of the first sleeve 7 near the closed end, facing away from the meshing opening 8.

[0022] In a preferred embodiment, the male snap fastener includes a second sleeve 9. One end of the second sleeve 9 has an opening that mates with the rod unit 2, and the other end is a closed end. A snap-fit ​​plate 10 is rotatably mounted on the side wall of the second sleeve 9 near the closed end. The rotation axis of the snap-fit ​​plate 10 is perpendicular to the axis of the second sleeve 9. One end of the snap-fit ​​plate 10 has a biting block 11 that mates with the snap-fit ​​opening 8. A torsion spring (not shown in the figure) is mounted on the rotation axis of the snap-fit ​​plate 10, which is rotatably connected to the second sleeve 9. The two ends of the snap-fit ​​plate 10 are rotatably connected to the side wall of the second sleeve 9 near the closed end. A preset gap (e.g., ...) is formed between the end of the snap-fit ​​plate 10 facing away from the biting block 11 and the second sleeve 9. Figure 6 As shown in the diagram, with this configuration, during use, the user can press the end of the locking plate 10 facing away from the bite block 11, causing the bite block 11 to disengage from the engagement opening 8, thus facilitating folding. When the torsion spring is in its normal state, the bite block 11 is inserted into the engagement opening 8; when the end of the locking plate 10 facing away from the bite block 11 moves towards the second sleeve 9, the torsion spring is twisted and the bite block 11 disengages from the engagement opening 8. With this configuration, after the rod units 2 are axially connected, the bite block 11 engages within the engagement opening 8, thereby axially fixing the two adjacent rod units 2 together.

[0023] As a preferred embodiment, the projection of the engagement opening 8 onto a plane perpendicular to the rotation axis of the locking plate 10 is a right-angled triangle. One right-angled side of the right-angled triangle is parallel to and faces away from the axis of the rod unit 2, while the other right-angled side faces the end of the rod unit 2 where the snap-fit ​​female head is located. This makes the free end of the bite block 11 a pointed shape, facilitating its insertion into the engagement opening 8.

[0024] As a preferred embodiment, the covering 1 is made of canvas.

[0025] As a preferred method, the outer fabric 1 is fixedly connected to both ends of the rod unit 2 by rivets. This rivet connection is relatively convenient.
