[0058] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0059] Embodiment 1

[0060] Refer to the attached drawings of the specification, such as Figure 1-Figure 16 As shown, a rod connection assembly proposed in the present application, connecting rods 2 are arranged on both sides of a connecting member 1, wherein the connecting member 1 includes:

[0061] The first sleeve 11 and the second sleeve 12 are hingedly connected. The specific structure is: a first hinged portion 112 is protrudingly provided on the end surface of the first sleeve 11, and a second hinged portion 122 is protrudingly provided on the end surface of the second sleeve 21, wherein hinge holes are provided at corresponding positions of the first hinged portion 112 and the second hinged portion 122, and the hinge connection between the first sleeve 11 and the second sleeve is realized by inserting the third pin 17 into the hinge hole, and the third pin 17 and the hinge hole can be clearance-matched to ensure the smooth rotation process of the first sleeve 11 or the second sleeve 12 around the third pin 17. Both ends of the first sleeve 11 and the second sleeve 12 are open, and the connecting rod 2 is divided into a hollow first connecting rod 21 and a second connecting rod 22, and the first connecting rod 21 and the second connecting rod 22 are respectively inserted into the first sleeve 11 and the second sleeve 12 to realize the fixing of the connecting rod 2 and the connecting member 1.

[0062] The connector 1 also includes a movable block 13, which is located in the first connecting rod 21 inserted into the first sleeve 11. An active space 131 is dug in the movable block 13, and the length of the active space 131 is one-third to two-thirds of the length of the movable block 13, and the active space 131 is located at the right end of the movable block 13. An opening is set on the side of the active space 131, and the upper and lower surfaces of the movable block 13 are hollowed out. A spring 132 is tightly installed on the right side of the movable block 13, and a fourth pin 133 is set on the right end of the spring 132. The fourth pin 133 passes through the first connecting rod 21 and the first sleeve 11 from the inside to the outside in turn, completing the fixation of the position of the fourth pin 133. It also includes a first pin 15 and a second pin 16, the first pin 15 passes through the first connecting rod 2, and the spring 132 is limited to the first pin 15; the second pin 16 passes through the second sleeve 12 and the second connecting rod 22 in turn, and fixes the second connecting rod 22 to the second sleeve 12.

[0063] The connecting member 1 also includes a sliding portion 14, which is fixedly connected to the movable block 13. The specific structure is as follows: the sliding portion 14 includes a pressing plate 141 with anti-slip patterns or protrusions on the surface, the two ends of the pressing plate 141 are tilted, and the pressing plate 141 and the movable block 13 are connected by a connecting plate 142. The connecting plate 142 is inserted into the movable block 13 through the sliding groove 111 to achieve a fixed connection between the pressing plate 141 and the movable block 13. The sliding groove 111 is transversely arranged on the side of the first sleeve 11, and the sliding portion 14 moves along the sliding groove 111. In addition, in order to cooperate with the movement process, a sliding groove is also arranged at the corresponding position of the first connecting rod 21.

[0064] According to the above structure, Figures 3 to 6 The specific working process of the rod connection assembly is as follows:

[0065] like Figure 3 As shown, in the initial state, the movable block 13 is completely located in the first connecting rod 21, and the spring 132 located on the right side of the movable block 13 is in a compressed state; when not affected by external forces, as shown in FIG. Figure 4 As shown, at this time, the spring 132 pushes the movable block 13 to move to the left, and the sliding portion 14 moves to the left along the sliding groove 111, so that the left end of the movable block 13 enters the second connecting rod 22. At this time, the first connecting rod 21 and the second connecting rod 22 are supported by the movable block 13, so the first connecting rod 21 or the second connecting rod 22 cannot be folded;

[0066] When the first connecting rod 21 or the second connecting rod 22 needs to be folded, Figure 5As shown, at this time, the pressing plate 141 is pressed and pushed to move rightward. The pressing plate 141 drives the movable block 13 to move rightward in the process of moving along the slide groove 111, until the movable block 13 entering the second connecting rod 22 is completely withdrawn into the first connecting rod 21. With the movement of the movable block 13, the spring 132 is gradually compressed. At this time, there is no support between the first connecting rod 21 and the second connecting rod 22. Since the first sleeve 11 and the second sleeve 12 are hinged, the first connecting rod 21 and the second connecting rod 22 can be folded; finally, as shown in FIG. Figure 6 As shown, after the first connecting rod 21 or the second connecting rod 22 is folded, without being affected by other external forces, the spring 132 rebounds to push the movable block 13 upward out of the first connecting rod 21 .

[0067] In addition, as required, a docking plate 143 is extended on the top of the pressing plate 141. The shape of the docking plate 143 is L-shaped or T-shaped. The surface of the docking plate 143 in contact with the first sleeve 11 is an arc surface, so that the shape of the docking plate 143 is more adapted to the shape of the first sleeve 11. Adapting to the docking plate 143, a docking groove 121 is provided on the second sleeve 12. When the movable block 13 is pushed to move toward the second connecting rod 22, the docking plate 143 is inserted into the docking groove 121, so that the connection between the first connecting rod 21 and the second connecting rod 22 is more stable.

[0068] In order to fix the movable block 13 after it moves, the connecting member 1 includes a first pin 15 and a second pin 16. The first pin 15 passes through the first connecting rod 21 and a protrusion 134 provided at the right end of the movable block 13. The protrusion 134 is located inside the spring 132. By providing the protrusion 134, the end of the spring 132 is sleeved outside the protrusion 134, thereby preventing the spring 132 from slipping.

[0069] Refer to the attached drawings of the specification, such as Figure 9-Figure 16 As shown, a fence proposed in the present application includes an upper frame 31 and a lower frame 32 correspondingly arranged up and down, and a vertical support rod 4 arranged between the upper frame 31 and the lower frame 32. The upper frame 31 and the lower frame 32 are polygonal frame structures surrounded by multiple connecting rods 2, and the connecting member 1 is connected to two adjacent connecting rods 2 in the same direction. Articulated seats 5 are respectively arranged at the corners of the upper frame 31 and the lower frame 32, and the connecting rods 2 are hinged to the articulated seats 5. The two ends of the support rod 4 are respectively connected to the upper and lower articulated seats 5.

[0070] Specifically, the articulated seat 5 includes a first articulated seat 51 located on the upper frame 31 and a second articulated seat 52 located on the lower frame 32. The first articulated seat 51 includes two first articulated grooves 511 perpendicular to each other in the horizontal direction and a third sleeve 512 arranged in the vertical direction. The second articulated seat 52 includes two second articulated grooves 521 perpendicular to each other in the horizontal direction and a fourth sleeve 522 arranged in the vertical direction. The notches of the first articulated groove 511 and the second articulated groove 521 are arranged opposite to each other, and the connecting rod 2 is respectively articulated with the first articulated groove 511 and the second articulated groove 521. The two ends of the support rod 4 are respectively inserted into the third sleeve 512 and the fourth sleeve 522. At this time, the support rod 4 is fixed after being inserted into the articulated seat 5, and the connecting rod 2 connected to both sides of the articulated seat 5 can be folded.

[0071] For a long connecting rod, in order to avoid collision during the folding process of the connecting rod 2, the first hinge groove 511 and the second hinge groove 521 are staggered in the horizontal direction. At this time, the second hinge groove 521 is located on the inner side of the first hinge groove 511. Fig.14 , Fig.15 It can be seen that the distance between the second hinge groove 521 and the fourth sleeve 522 is greater than the distance between the first hinge groove 511 and the third sleeve 512, and the upper and lower ends of the support rod 4 need to be inserted into the third sleeve 512 and the fourth sleeve 522 respectively. Therefore, the connecting rod located on the upper frame 31 will be staggered in the horizontal direction from the connecting rod swing of the lower frame 32 when swinging, avoiding the problem of the connecting rod of the upper frame 31 and the connecting rod of the lower frame 32 affecting each other when folding.

[0072] Since the connecting member 1 also needs to be controlled during use, if the connecting rods of the frame are all connected by the connecting member 1, the eight connecting members 1 need to be adjusted, which brings inconvenience to the unfolding and folding of the fence. Therefore, based on this situation, this embodiment proposes an improved solution, which is as follows: a support member 6 is set between two adjacent connecting rods 2 located in the same direction of the upper frame 31, and the support member 6 includes two support plates 61 and a fixing plate 62 that connects the tops of the two support plates 61. The first card slot 63 and the second card slot 64 are symmetrically arranged on both sides of the support plate 61. The first card slot 63 is a straight line, and the second card slot 64 includes a horizontal section and an inclined section. The end of the connecting rod 2 is penetrated by a first frame rod 65 and a second frame rod 66, and the connecting rod 2 can rotate around the first frame rod 65 and the second frame rod 66. The first frame rod 65 moves along the first card slot 63, and the second frame rod 66 moves along the second card slot 64. When the angle between adjacent connecting rods 2 is 0° or 180°, the adjacent connecting rods 2 are in an unfolded state, the first frame rod 65 presses against the end of the first slot 63, and the second frame rod 66 presses against the end of the horizontal section in the second slot 64, thereby fixing the connecting rod 2. When the angle between adjacent connecting rods 2 is 0°-180°, the adjacent connecting rods 2 are in a folded state, the first frame rod 65 moves along the first slot 63, and the second frame rod 66 moves along the inclined section of the second slot 64.

[0073] Taking the fence 3 as an example, when the fence is unfolded, the connecting piece 1 at the bottom makes the angle between the connecting rods 2 on both sides 0° or 180°. At this time, the lateral length of the fence 3 is twice the length of the connecting rod 2. The length of the adjacent connecting rod 2 located on the upper frame 31 allows the connecting rod 2 to be tightened in the first slot 63 and the second slot 64, thereby also making the surface of the connecting rod 2 of the upper frame 31 flush; and when the angle between the connecting rods 2 of the lower frame 32 is 0° or 180°, the connecting rod 2 is in a folded state, the lateral length of the fence 3 is less than twice the length of the connecting rod 2, and the tightening state between the connecting rod 2 and the first slot 63 is cancelled. At this time, the second frame rod 66 enters the inclined section from the horizontal section of the second slot 64, and the connecting rod 2 swings and folds with the first frame rod 65 and the second frame rod 66.

[0074] In addition, in order to improve the structural strength of the fence, the connecting rod 2 located on the upper frame 31 can have two connecting rods arranged one above the other, namely, the third connecting rod 23 and the fourth connecting rod 24. At this time, the ends of the adjacent third connecting rods 23 are mounted on the support member 6 through the first mounting rod 65 and the second mounting rod 66. The bottom of the support member 6 is also symmetrically provided with shaft holes, and the end of the fourth connecting rod 24 is penetrated by the third mounting rod 67, and the third mounting rod 67 passes through the shaft hole so that the fourth connecting rod 24 can be rotatably connected to the support member 6.

[0075] The folding process of the fence is as follows Figure 12-16As shown, when the connecting member 1 is unlocked, the connecting rods 2 on both sides of the connecting member 1 on the lower frame 32 are lifted upward; as the horizontal length of the fence decreases, the first frame rod 65 and the second frame rod 66 on the support member 6 change from a tight state to a sliding state along the first slot 63 and the second slot 64. As the first frame rod 65 and the second frame rod 66 move, the connecting rod 2 on the upper frame 31 swings downward to achieve the folding of the fence, and finally becomes as shown in FIG. Fig.16 The middle fence as shown in the figure is transformed into a rectangular parallelepiped shape that is longer in the vertical direction; during the folding process, since the hinge grooves of the first hinge seat 51 located at the corner of the upper frame 31 and the second hinge seat 52 located at the corner of the lower frame 32 are staggered, the connecting rod 2 on the upper frame 31 will not collide with the connecting rod 2 on the lower frame 32 during the folding process. Figure 14-16 As shown, at this time, the connecting rod 2 of the upper frame 31 is located on the outside of the fence, and the connecting rod 2 of the lower frame 32 is located on the inside of the fence.

[0076] The above embodiment is a frame structure of a fence, which can be used in conjunction with a cloth cover or a cloth net during use of the fence. Specifically, the cloth cover or the cloth net is set on the fence, and the edge of the cloth cover or the cloth net can be tied to the connecting rod 2 of the fence by a plurality of straps. The fabric can be a soft material such as cotton, polyester, linen, etc., and the cloth cover is a blend of one or more of the above materials.

[0077] Embodiment 2

[0078] Refer to the attached drawings of the specification, such as Figure 17-Figure 19 As shown, a fence proposed in the present application includes a plurality of rod connection assemblies on one side of the fence. Adjacent rod connection assemblies are connected by an intermediate hinge 7, which is a T-shaped hinge, including two hinge ports 71 arranged on the left and right sides of the upper end and a fifth sleeve 72 located in the center. When multiple rod connection assemblies are connected, the adjacent connecting rods 2 of each rod connection assembly located in the same direction are hinged to the hinge port 71, and the support rod 4 between two adjacent rod connection assemblies is inserted into the fifth sleeve 72.

[0079] Embodiment 3

[0080] Refer to the attached drawings of the specification, such as Fig. 20 As shown, the fence proposed in the present application has a plurality of drawstrings 8 disposed on the lower frame 32 of the fence, and end sleeves 81 are disposed at both ends of the drawstrings 8. The end sleeves 81 at both ends of the same drawstring 8 are respectively sleeved on two oppositely disposed connecting rods 2. Fig. 20 For example, two drawstrings 8 form a cross shape. In order to avoid affecting the use of the connector 1, the center of the drawstring 8 deviates from the center of the lower frame 32. When installing, first unlock the connector 1, and the end sleeve 81 can be installed at the connecting rod 2 at both ends of the connector 1. The end sleeve 81 can be formed by sewing the drawstring 8 into a cylindrical shape, or by setting Velcro for attachment.

[0081] After unlocking the connecting piece 1, by pulling the drawstring 8 upwards, the connecting rods 2 around the lower frame 32 can be pulled at the same time, which facilitates the folding of the fence.

[0082] In summary, the rod connection assembly and fence proposed in this application have the following advantages:

[0083] 1. In the present application, a connecting member 1 is provided between the two connecting rods 2, and the connecting member 1 includes two connected first sleeves 11 and second sleeves 12. Driven by the sliding part 14, the movable block 13 enters the second sleeve 12, so that the connection between the two adjacent connecting rods 2 is supported. Therefore, the surfaces of the two adjacent connecting rods 2 are in a flush state during construction, and there will be no problem of a certain connecting rod swinging downward; the spring 132 is restricted between the movable block 13 and the fourth pin shaft 133. In the process of the movable block 13 entering the second sleeve 12, due to the fixation of the end rod 133, the spring 132 located in the movable space contacts and squeezes the end rod as the movable block 13 moves, until the spring 132 is compressed to the shortest, and at this time the movable block 13 no longer moves into the second sleeve 12.

[0084] 2. When the connecting rod 2 needs to be folded, the movable block needs to be completely returned from the second sleeve 12 to the first sleeve 11. At this time, due to the continuous accumulation of elastic potential energy of the spring 132, the spring 132 drives the movable block 13 to return to the first sleeve 11 until the elastic potential energy disappears. At this time, the movable block 13 is completely returned to the first sleeve 11, and there is no support between the two adjacent connecting rods 2; at this time, since the first sleeve 11 and the second sleeve 12 are connected by a hinge, one of the connecting rods can swing to achieve the folding of the two connecting rods.

[0085] 3. The first hinge groove 511 and the second hinge groove 521 are staggered in the horizontal direction, and the second hinge groove 521 is located on the inner side of the first hinge groove 511. At this time, the distance between the second hinge groove 521 and the fourth sleeve 522 is greater than the distance between the first hinge groove 511 and the third sleeve 512, and the upper and lower ends of the support rod 4 need to be inserted into the third sleeve 512 and the fourth sleeve 522 respectively. Therefore, when the connecting rod of the upper frame 31 swings, it will be staggered with the swing of the connecting rod of the lower frame 32 in the horizontal direction, avoiding the problem that the connecting rod of the upper frame 31 and the connecting rod of the lower frame 32 affect each other when folding.

[0086] 4. A support member 6 is provided between two adjacent connecting rods 2 located in the same direction of the upper frame 31. When the angle between the adjacent connecting rods 2 is 0° or 180°, the adjacent connecting rods 2 are in an unfolded state, the first frame rod 65 presses against the end of the first card slot 63, and the second frame rod 66 presses against the end of the horizontal section in the second card slot 64, and the connecting rod 2 is fixed by pressing; and when the angle between the adjacent connecting rods 2 is 0°-180°, the adjacent connecting rods 2 are in a folded state, the first frame rod 65 moves along the first card slot 63, and the second frame rod 66 moves along the inclined section of the second card slot 64. In this way, when the connecting member 1 folds the connecting rod 2 of the lower frame 32, the connecting rods 2 located in the upper frame 31 can fold themselves without controlling the connecting member 1, so that the fence is faster and more convenient when stored.
