[0091] In order to explain the technical content, structural features, achieved objectives and effects of the technical solution in detail, the following is a detailed description in conjunction with specific embodiments and accompanying drawings.

[0092] In the prior art, although the side structure of the fence frame is attempted to be constructed by a pair of long-span first upper rods and second upper rods, supplemented by a single intermediate connecting piece and a pair of diagonal braces, when faced with large external forces, this design exposes the defect of insufficient supporting capacity, especially in terms of bearing capacity and stability.

[0093] In view of the above problems, this embodiment provides an improved fence frame side structure, which is intended to significantly enhance the stability and load-bearing capacity of the structure. Figure 1 , this embodiment provides a side structure of a fence frame, including a first rod body 41, a second rod body 42, a third rod body 43, a hinge assembly 10, a second support rod 32, a fourth component 14, a fifth component 15 and a sixth component 16;

[0094] The first rod 41 and the second rod 42 are arranged on the left and right sides, and the third rod 43 is located at the lower side of the second rod 42. The first rod 41, the second rod 42, and the third rod 43 are connected by a hinge assembly 10, so that the first rod 41, the second rod 42, and the third rod 43 can rotate relative to or opposite to each other;

[0095] The second support rod 32 is located on a side of the second rod body 42 away from the third rod body 43, and a fourth component 14 is slidably sleeved on the outside of the second support rod 32. The fourth component 14 is hinged to one end of the third rod body 43 away from the first rod body 41, and a fifth component 15 is fixed to the outside of the second support rod 32. The fifth component 15 is located above the fourth component 14, and a limiting structure for limiting is provided on the fifth component 15 and the fourth component 14. A sixth component 16 is provided on the upper end of the second support rod 32, and the sixth component 16 is hinged to one end of the second rod body 42 away from the first rod body 41.

[0096] The first innovation of this embodiment is that the first rod and the second rod (the whole formed by the two is equivalent to the first upper rod or the second upper rod in the prior art) are arranged horizontally, and the third rod is located below the second rod, and a stable triangular foundation is formed between the third rod, the second rod and the second support rod. The first rod, the second rod and the third rod are connected by a well-designed hinge assembly 10, which realizes flexible rotation between them, whether it is relative rotation or opposite movement, it can ensure that the overall structure can adapt to different terrain conditions and external forces.

[0097] The second innovation of this embodiment is that the second support rod not only provides direct auxiliary support for the second rod body, but also establishes a dynamic connection with the third rod body through the fourth member. The sliding sleeve design of the fourth member gives the system more adjustment space. The fifth member is fixed on the second support rod as a limit device, which effectively controls the range of movement of the fourth member and ensures the stability of the structure during dynamic adjustment.

[0098] That is, when external forces act on the fence, the hinge assembly 10 between the first to third rods allows the structure to deform within a certain range to absorb energy, while the second support rod and its assembly play a role in dynamic adjustment and enhanced support. The sliding and hinge mechanism of the fourth component enables the fence to automatically fine-tune according to the force conditions, and the limit structure of the fifth component avoids excessive deformation and ensures structural safety. The addition of the sixth component, through the hinge connection with the second rod, provides additional vertical support and stability for the entire structure.

[0099] In addition, the length of the first rod body or the second rod body is greatly shortened compared to the length of the first upper rod body or the second upper rod body in the prior art, which makes it easier to fold and greatly reduces the volume when stored. The small size after folding is not only convenient for transportation and storage, but also reduces the space occupied when not in use, thereby improving the convenience and practicality of use.

[0100] In this embodiment, the hinge assembly 10 includes a first assembly, a second assembly and a third assembly. The first assembly is connected to the first rod body 41. The first assembly is provided with a first hinge hole 2121 and a second hinge hole 2122 which are spaced apart from each other. The first hinge hole 2121 is hinged to the second assembly, and one end of the second assembly away from the first hinge hole 2121 is connected to the second rod body 42. The second hinge hole 2122 is hinged to the third assembly, and one end of the third assembly away from the second hinge hole 2122 is hinged to the third rod body 43.

[0101] In some embodiments, instead of the first component being provided with two hinge holes, the second component and the third component are respectively hinged to the two hinge holes of the first component. Alternatively, the second component may be provided with two hinge holes, so that the first component and the third component are respectively hinged to the two hinge holes of the second component.

[0102] In this embodiment, the first component includes a first member 11 and a first connecting member 21, the first member 11 is connected to the first rod body 41, the first connecting member 21 includes a first connecting portion 211 and a second connecting portion 212, the first connecting portion 211 and the second connecting portion 212 are arranged at a first preset angle, the first connecting portion 211 is connected to the first member 11, and the second connecting portion 212 is provided with a first hinge hole 2121 and a second hinge hole 2122;

The first connecting hole, the first slot 1211 and the first hinged hole 2121 are coaxial and penetrated by a first pin.

[0104] The third component includes a third member 13 and a third connecting member 23. The third member 13 is connected to the third rod body 43. An end of the third member 13 away from the third rod body 43 is provided with a second hinged portion 131 for inserting the second connecting portion 212. The second hinged portion 131 is provided with second slots 1311 on both sides of the second hinged hole 2122. The third connecting member 23 is provided on the front side or the rear side of the third rod body 43. The third connecting member 23 has a second connecting hole. The second connecting hole, the second slot 1311 and the second hinged hole 2122 are coaxial and penetrated by a second pin.

[0105] See also Figure 3 In this embodiment, a first groove 111 is provided on the first component 11, the first connecting portion 211 and the second connecting portion 212 are arranged at a first preset angle, the first connecting portion 211 is embedded in the first groove 111, the second connecting portion 212 and the first hinged portion 121 are hinged to the first hinged hole 2121 through a pin, and the second connecting portion 212 and the second hinged portion 131 are hinged to the second hinged hole 2122 through a pin.

[0106] In this embodiment, the first member 11 is arranged at the end of the first rod body 41, the second member 12 is arranged at the end of the second rod body 42, and the third member 13 is arranged at the end of the third rod body 43. The first member 11, the second member 12 and the third member 13 are rotatably connected by the first connecting member 21. Specifically, the first connecting member 21 includes a first connecting portion 211 and a second connecting portion 212. The first connecting portion 211 and the second connecting portion 212 are arranged at a first preset angle. The specific value of the first preset angle can be set according to actual needs, such as Figure 3 The first preset angle shown is 90 degrees, and the first connection portion 211 and the second connection portion 212 are connected in an L-shape.

[0107] Among them, the first component 11 has a first groove 111, and the first connecting part 211 is placed in the first groove 111. Optionally, the fastening connection between the first component 11 and the first connecting part 211 can be achieved by a locking fastener; the second component 12 has a first hinge part 121, and the second connecting part 212 is provided with a first hinge hole 2121. The first hinge part 121 and the first hinge hole 2121 can be hinged through a pin shaft. The third component 13 has a second hinge part 131, and the second connecting part 212 is provided with a second hinge hole 2122. The second hinge part 131 and the second hinge hole 2122 can be hinged through a pin shaft.

[0108] Preferably, the first connection portion 211 and the second connection portion 212 form a T-shape or a Y-shape.

[0109] It should be noted that this embodiment does not limit the positional relationship between the second rod body 42 and the third rod body 43. In some preferred embodiments, the second rod body 42 is arranged above the third rod body 43, and the first hinge hole 2121 and the second hinge hole 2122 are spaced apart in the vertical direction.

[0110] In this embodiment, the other end of the first rod 41 is hinged to the end of the first support rod 31, one end of the second rod 42 is hinged to the end of the second support rod 32, and the third rod 43 is movably connected to the second support rod 32. When the second rod 42 and the third rod 43 rotate toward each other under the drive of the second component 12, the third component 13 and the first connecting member 21, the distance between the first support rod 31 and the second support rod 32 can be expanded. At the same time, the first rod 41, the second rod 42 and the third rod 43 are stretched to a state close to a straight line, that is, at this time, the connection between the second rod 42 and the third rod 43 still has a certain curvature. At this time, the first rod 41, the second rod 42 and the third rod 43 are in a fully extended state, and the first support rod 31 is farthest from the second support rod 32, that is, the overall fence frame 71 is in an extended state. Figure 6 shown.

[0111] When the third rod 43 and the second rod 42 move away from each other, the second support rod 32 moves close to the first support rod 31, further driving the first rod 41 to bend obliquely downward, the second rod 42 to bend obliquely upward, and the third rod 43 to bend obliquely downward until the distance between the second support rod 32 and the first support rod 31 is the smallest. The specific change process can be referred to Figures 7 to 10 As shown, the folding operation of the entire fence frame 71 is realized.

[0112] See also Figure 3In the present embodiment, the second connecting member 22, the third connecting member 23 and the first connecting member 21 are all sheet structures, wherein the second connecting member 22 is locked on the outer surface of the end of the second rod body 42 by a fastener, and the third connecting member 23 is locked on the outer surface of the end of the third rod body 43 by a fastener. Preferably, the second connecting member 22 and the third connecting member 23 are arranged on the same side, the first connecting hole, the first slot hole and the first hinge hole 2121 are coaxial, and the second connecting hole, the second slot hole and the second hinge hole 2122 are coaxial. When a pin shaft is used for hinge connection, the second connecting member 22 and the third connecting member 23 can reinforce the hinge area of ​​the second component 12 and the third component 13, thereby improving the connection stability between the second rod body 42, the third rod body 43 and the first rod body 41.

[0113] In this embodiment, when in use, the second component 12 and the third component 13 can be directly rotated towards each other and then abutted against each other to achieve the fixation of the second rod body 42 and the third rod body 43, and at the same time form a fully expanded state with the first rod body 41, so that the first support rod 31 and the second support rod 32 are farthest apart, and the first support rod 31, the second support rod 32, the first rod body 41, the second rod body 42 and the third rod body 43 form a side structure of a fence. When storage is needed, it is only necessary to rotate the second component 12 and the third component 13 away from each other, and the first support rod 31 and the second support rod 32 can be driven closer to each other under the action of inertia, completing the folding operation of the entire fence side, which is easy to use.

[0114] In this example, see Figure 2 and Figure 3 In some embodiments, the second component 12 has a first limiting protrusion 122, which is arranged on the side of the second component 12 facing the third component 13; the third component 13 has a second limiting protrusion 132, which is arranged on the side of the third component 13 facing the second component 12; the first limiting protrusion 122 can be rotated to the first preset position under the drive of the second rod body 42, and the second limiting protrusion 132 can be rotated to the second preset position under the drive of the third rod body 43, so that the first limiting protrusion 122 and the second limiting protrusion 132 stop each other, so that the first rod body 41 and the second rod body 42 remain relatively fixed.

[0123] When the fourth component 14 moves to the preset position, the first limiting member 51 is placed in the first pressing hole 143 , and a portion of the first limiting member 51 protrudes out of the first pressing hole 143 , so that the fourth component 14 is fixed relative to the second support rod 32 .

[0124] In this embodiment, optionally, the number of the third connection parts 141 can be set according to actual needs. For example, when a second support rod 32 is shared, the number of the third connection parts 141 is two, and one third connection part 141 is hinged to a third rod body 43. The third connection part 141 is provided with a first rotation opening 144, and the opening angle of the first rotation opening 144 can be set according to actual needs.

[0127] In this embodiment, the cross section of the fifth member 15 is non-circular and can be inserted into the fourth member 14. The cross section of the fourth connecting portion 142 of the fourth member 14 matches the non-circular cross section of the fifth member. The fifth member 15 can only be raised and lowered in the fourth connecting portion 142 and cannot be rotated left and right, which is conducive to the alignment between the various components of the limiting structure. Preferably, the portion of the fifth member 15 inserted into the fourth member 14 is conical, which can also play a role in limiting.

[0128] In this embodiment, the first stopper 51 can be understood as a button-type structure. A first elastic member is provided between the first stopper 51 and the second support rod 32. The first elastic member can be compressed when the first stopper 51 is under pressure, so that the first stopper 51 is embedded in the second support rod 32. When the force is released, the elastic potential energy of the first elastic member is released, so that the end of the first stopper 51 protrudes out of the outside of the second support rod 32. A first pressing hole 143 is provided on the fourth connecting portion 142.

The preset position here is the position of the end of the third rod 43 on the second support rod 32 when the second rod 42 and the third rod 43 are against each other.

[0129] See also Figure 4 In some embodiments, the fourth member 14 is further provided with a first pressing plate 145, which serves as a part of the limiting structure.

This method can increase the force area of ​​the human hand during the pressing process and improve the comfort of use. It should be noted that the first pressing hole 143 and the first pressing plate 145 serve as a part of the limiting structure.

[0130] When the third rod 43 needs to be rotated, the first limiter 51 can be pressed through the first pressing hole 143 to disengage the fourth connection portion 142 from the fixed state with the second support rod 32 and slide relative to the second support rod 32 to adjust the rotation angle of the third rod 43.

The fifth connection part 161 has a second rotation opening, and the second rod body 42 can rotate relative to the fifth connection part 161 in the second rotation opening. Optionally, the number of the fifth connection parts 161 can be set according to actual needs. For example, when a second support rod 32 is shared, the number of the fifth connection parts 161 is two, and one fifth connection part 161 is hinged to one second rod body 42. The fifth connection part 161 has a second rotation opening, and the opening angle of the second rotation opening can be set according to actual needs. This method can realize the limitation of the rotation range of the second rod body 42. It can be seen that the second rotation opening is arranged opposite to the first rotation opening 144, which is consistent with the rotation mode of the second rod body 42 and the third rod body 43.

[0132] In this embodiment, when in use, the second component and the third component can be directly rotated towards each other and then abutted against each other to achieve fixation of the second rod body and the third rod body, and at the same time form a fully expanded state with the first rod body, so that the first support rod and the second support rod are farthest apart, and the first support rod, the second support rod, the first rod body, the second rod body and the third rod body form a side structure of a fence. When storage is needed, it is only necessary to rotate the second component and the third component away from each other, and the first support rod and the second support rod can be driven closer to each other under the action of inertia, completing the folding operation of the entire fence side, which is easy to use.
