[0025] This utility model proposes a novel fence frame.

[0026] In this embodiment of the utility model, such as Figs. 1 to 4As shown, the new type of fence frame includes an upper frame 1, a lower frame 2, and several uprights 3. The upper and lower ends of the uprights 3 are fixedly connected to the upper frame 1 and the lower frame 2, respectively. At least one support rod 4 is provided between two adjacent uprights 3. The support rod 4 includes an upper section 41 that is pivotally connected to the upper frame 1 and a lower section 42 that is pivotally connected to the lower frame 2. The upper section 41 can swing relative to the upper frame 1 between a position linearly aligned with and offset from the lower section 42. The lower section 42 can swing relative to the lower frame 2 between a position linearly aligned with and offset from the upper section 41. A locking element is also provided. When the upper section 41 and the lower section 42 are linearly aligned, the upper section 41 and the lower section 42 are locked by the locking element.

[0027] It should be noted that the upper frame 1 and the lower frame 2 are foldable structures. The connection between the upper frame 1, the lower frame 2 and the uprights 3 can be referred to the existing technology, such as the foldable fence structure disclosed in utility model patent number 202223599528.4. The specific structural principle will not be described in detail here.

[0028] Specifically, the locking component includes a sleeve 51, which is used to cover the free ends of the upper section 41 and the lower section 42, thereby locking the upper section 41 and the lower section 42. For example, in one embodiment, the sleeve is an independent part, using a hinge structure to achieve opening and closing. During operation, the sleeve is first opened, aligned with the free ends of the upper and lower sections, and then closed to cover the free ends of the upper and lower sections. Finally, the sleeve, upper section, and lower section are locked by screws or by a snap-fit ​​structure.

[0029] Specifically, in one embodiment, the sleeve 51 is movably sleeved on the free end of the upper section 41, and can move relative to the upper section 41 between a position that is inserted into the free end of the lower section 42 to lock the upper section 41 and the lower end and a position that is away from the unlocked position.

[0030] Alternatively, as shown in this embodiment, the sleeve 51 is movably sleeved on the free end of the lower section 42, and can move relative to the lower section 42 between a position where it is inserted into the free end of the upper section 41 to lock the upper section 41 and the lower section 42 and a position away from the unlocked position.

[0031] The locking mechanism also includes a top spring 52. When the sleeve 51 is located on the upper section 41, gravity allows the sleeve 51 to automatically move towards the free end of the lower section 42 for insertion. When the sleeve 51 is located on the lower section 42, the top spring 52 applies a spring force to the sleeve 51 to move it towards the free end of the upper section 41. This prevents the upper section 41 and lower section 42 from failing to lock due to the sleeve 51 automatically moving away from the free end of the upper section 41.

[0032] Specifically, when the sleeve 51 is located in the lower section 42, the free end of the lower section 42 has an elongated positioning hole 43. The sleeve 51 is provided with a limiting pin 44 that can pass through the positioning hole 43. The limiting pin 44 can move with the movement of the sleeve 51 to abut against one end of the positioning hole 43 or to abut against the other end of the positioning hole 43. This limits the range of motion of the sleeve 51 and prevents the sleeve 51 from dislodging from the lower section 42 due to excessive displacement. Of course, when the sleeve 51 is located in the upper section 41, the positioning hole 43 can also be provided at the free end of the upper section 41.

[0033] Specifically, the top spring 52 is located inside the lower section 42, and the lower section 42 is provided with a positioning member 45 for elastically abutting against the lower end of the top spring 52. The end of the top spring 52 away from the positioning member 45 elastically abuts against the limiting pin 44.

[0034] Specifically, one end of the upper segment 41 is pivotally connected to a first connecting seat 46, which is movably sleeved on the upper frame 1 to realize the pivotal connection between the upper segment 41 and the upper frame 1.

[0035] Specifically, the first connecting seat 46 is locked to the upper frame 1 by the first rivet 47.

[0036] Specifically, one end of the lower segment 42 is pivotally connected to a second connecting seat 48, which is movably sleeved on the lower frame 2 to realize the pivotal connection between the lower segment 42 and the lower frame 2.

[0037] Specifically, the second connecting seat 48 is locked to the lower frame 2 by the second rivet 49.

[0038] Specifically, the upper segment 41 and the lower segment 42 have the same length, or the upper segment 41 is longer than the lower segment 42, or the lower segment 42 is longer than the upper segment 41.

[0039] This utility model includes an upper frame, a lower frame, and multiple uprights. The upper and lower frames are connected by the uprights, and at least one support rod is set between two adjacent uprights. The support rod mainly includes an upper section and a lower section. The upper section is pivotally connected to the upper frame and can swing between linearly aligned with and offset from the lower section. The lower section is pivotally connected to the lower frame and can swing between linearly aligned with and offset from the upper section. When the upper and lower sections are linearly aligned, they can be locked by locking devices. When the fence frame is unfolded, the upper and lower sections are swung to linear alignment and then locked by locking devices to form a support rod, thereby strengthening the structural strength of the fence frame, especially the part of the upper frame between two adjacent uprights. After releasing the locking of the upper and lower sections, the fence frame can be folded up. Compared with the traditional method, this utility model has a simple overall structure, and the structural strength of the part of the upper frame between two adjacent uprights is high after unfolding, making it less prone to deformation or breakage under external pressure.

[0040] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
