DETAILED DESCRIPTION

[0032] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0033] Example 1

[0034] like Figure 1-Figure 3 As shown, an umbrella-shaped folding enclosure includes a support rod 1, an umbrella frame connected to the support rod 1, and an enclosure fabric 2 mounted on the umbrella frame. The umbrella frame includes a plurality of support bones 3 and a plurality of long bones 4. The ends of the support bones 3 are connected to the support rod 1 and the long bones 4 respectively. When the folding enclosure is unfolded, the support rod 1 is supported on the ground, so that the enclosure fabric 2 faces outward. The long bones 4 are used to connect to the enclosure fabric 2, so that the enclosure fabric 2 is fully unfolded and shaped. The support bones 3 and the support rod 1 work together to expand or retract the long bones 4.

[0035] Similar to the shape of an umbrella, the top of the support rod 1 is usually connected to the upper nest 5, and the lower part of the upper nest 5 is connected to the lower nest 6. The upper nest 5 is fixed to the support rod 1, and one end of each long bone 4 is rotatably connected to the upper nest 5, and the other end is connected to the edge of the enclosure cloth 2. The lower nest 6 slides with the support rod 1, and one end of each support bone 3 is rotatably connected to the lower nest 6, and the other end is rotatably connected to the long bone 4. The expansion or folding of the folding enclosure is achieved by sliding the lower nest 6.

[0036] The present invention differs from the prior art in that the long bone 4 comprises several joints 401 connected sequentially by a first bending structure 7, which allows adjacent joints 401 to be bent or extended relative to each other. The support rod 1 comprises several connecting rods 101 connected sequentially by a second bending structure 8, which allows adjacent connecting rods 101 to be bent relative to each other at different angles. The first bending structure 7 is required to maintain the shape of the long bone 4 when the enclosure cloth 2 is extended, that is, to fix the two joints 401 at 180 degrees. However, it can be released after folding. The first bending structure 7 allows the long bone 4 to be folded into a shorter shape after folding, so that it can be used with larger enclosure cloths 2 and ultimately folded to a size that is convenient for storage (for example, in a car trunk). The second bending structure 8 is used to bend the support rod 1 at a certain angle, so that one end of the support rod 1 is supported on the ground and the other end supports the enclosure cloth 2 at an angle. Therefore, the second bending structure 8 is configured to fix two adjacent connecting rods 101 at different angles.

[0037] In this embodiment, each long bone 4 consists of two condyles 401, and the supporting bone 3 is connected to the condyle 401 near the support rod 1. There are four long bones 4 and four supporting bones 3 symmetrically arranged, and the ends of the four long bones 4 are connected to the four corners of the enclosure cloth 2, supporting the enclosure cloth 2 into a rectangular or square shape.

[0038] The first bending structure 7 can be, but is not limited to, the following structures:

[0039] like Figure 4 As shown, the first bending structure 7 includes a female lock 701, a male lock 702, and an unlocking button 703. The female lock 701 and the male lock 702 are respectively connected to two adjacent condyles 401. The female lock 701 and the male lock 702 are hinged to a first hinge axis 704. The unlocking button 703 is connected to the male lock 702. The female lock 701 is provided with a limiting groove 7011. The unlocking button 703 is connected to the male lock 702 and has a limiting portion 7031 that can engage with the limiting groove 7011 when the two condyles 401 are unfolded, thereby relatively fixing the two condyles 401. That is, when the limiting portion 7031 is inserted into the limiting groove 7011, the unlocking button 703 inhibits the two condyles 401 from rotating relative to each other. When the limiting portion 7031 is released from the limiting groove 7011, the two condyles 401 rotate about the first hinge axis 704.

[0040] The specific structure of the unlock button 703: the middle part of the unlock button 703 and the male lock 702 are hinged to the second hinge axis 705, the limit part 7031 is located at one end of the unlock button 703, and the other end of the unlock button 703 is in contact with the male lock 702 via a compression spring 706; the first hinge axis 704, the second hinge axis 705 and the central axis of the joint 401 are not parallel to each other. Figure 7 As shown, the second hinge axis 705 secures the middle position of the unlock button 703, and the elastic force of the compression spring 706 pushes one end of the unlock button 703 outward, causing the stopper 7031 at the other end of the unlock button 703 to extend out of the stop slot 7011. When the compression spring 706 is manually pressed on the portion of the unlock button 703 corresponding to the compression spring 706, the compression spring 706 contracts, causing the unlock button 703 to rotate about the second hinge axis 705, causing the stopper 7031 to disengage from the stop slot 7011. The male lock 702 and the female lock 701 are butted together at their ends, connected to the first hinge axis 704 only by side lugs. The non-parallel arrangement of the first hinge axis 704 and the second hinge axis 705 is intended to allow the first hinge axis 704 and the stop slot 7011 to avoid each other in the circumferential direction.

[0041] Second bending structure 8:

[0042] The second bending structure 8 in the present invention is similar to the connection structure between the first middle rod and the second middle rod in the prior art CN202321938316. The main difference lies in the number of teeth on the arc-shaped toothed disc. Therefore, the present invention will not describe it in detail, and its specific structure is not disclosed in the accompanying drawings. Other second bending structures 8 that can realize bending and fixing of the support rod 1 are also applicable to the present invention.

[0043] Similar to an umbrella structure, after the folding enclosure is unfolded, the lower nest 6 needs to be limited and fixed to prevent it from sliding relative to the support rod 1. When the folding enclosure needs to be folded, the umbrella folding button 9 is movably connected to the lower portion of the lower nest 6 to contact and fix it. The limiting structure of the folding enclosure of the utility model is as follows:

[0044] The support rod 1 is provided with an upper limit hole 102 and a lower limit hole 103. The upper limit hole 102 is installed with an upper limit member 10. The support rod 1 is provided with a first compression spring 11. The middle part of the first compression spring 11 can extend out of the lower limit hole 103. When the folding enclosure is in the unfolded state, the lower nest 6 is located between the upper limit member 10 and the first compression spring 11, and the umbrella folding button 9 is opposite to the middle part of the first compression spring 11. When it is necessary to fold the umbrella, press the umbrella folding button 9, the first compression spring 11 is pressed into the lower limit hole 103, and the lower nest 6 can pass through the lower limit hole 103 smoothly. Figure 5 As shown, a sleeve 15 is integrally provided below the lower nest 6, and a hole is correspondingly provided on the side of the sleeve 15. The umbrella folding button 9 is located at the hole. One end of the umbrella folding button 9 is fixed to the sleeve 15, and the other end slides relative to the lower nest 6. When the hole of the sleeve 15 is opposite to the lower limit hole 103, the protruding part of the first compression spring 11 pushes the umbrella folding button 9 outward through the hole, and the extended protruding part limits the lower nest 6 from sliding downward.

[0045] The upper limit member 10 can be a U-shaped compression spring, the two ends of which abut the inner wall of the support rod 1, and the middle bending part of the U-shaped compression spring extends out of the upper limit hole 102. The extended part is an arc-shaped bending structure, which can avoid damage to other parts and scratches on staff.

[0046] In this embodiment, two second bending structures 8 are provided. When the folding enclosure is in the unfolded state, the lower nest 6 is located on the connecting rod 101 connected to the long bone 4. Figure 3 As shown, the support rod 1 is bent from the inclined state at one end in contact with the ground to an approximately horizontal state connected to the enclosure cloth 2 by two second bending structures 8. The two bendings can improve the structural strength of the support rod 1.

[0047] Example 2

[0048] Based on the first embodiment, an extension rod 12 is sleeved on the end of the support rod 1 away from the enclosure cloth 2, and a connection hole 13 is provided at the sleeved portion of the two. An elastic locking pin 14 is provided inside the extension rod 12, and the projection 1401 of the elastic locking pin 14 extends out of the connection holes 13 of both the support rod 1 and the extension rod 12. The provision of the extension rod 12 can accommodate enclosure cloths 2 of a wider range of sizes and a wider range of working conditions, and can control the support rod 1 within a certain range for convenient storage. In the on-site environment, when the enclosure cloth 2 is too large or the support rod 1 is far from the ground due to the height difference, the extension rod 12 can play an auxiliary supporting role.

[0049] like Figure 3 、 Figure 6 and Figure 8 As shown, the end of the extension rod 12 is inserted into the support rod 1, and two connecting holes 13 are symmetrically provided on the extension rod 12 and the support rod 1. The elastic locking pin 14 is a U-shaped structure, and a protrusion 1401 is provided at both ends. The elastic locking pin 14 is located in the extension rod 12, and the protrusion 1401 extends out through the connecting hole 13. When the extension rod 12 needs to be removed, press the protrusion 1401 and pull the extension rod 12 outward.

[0050] Preferably, the lengths of the joints 401 and the supporting bones 3 are less than or equal to the length of the support rod 1 . When the foldable enclosure is in the retracted state, the total length of the foldable enclosure is approximately equal to the length of the support rod 1 .
