[0042] In the description of the present invention, it should be understood that the terms indicating orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention; in the description of the present invention, the meaning of "multiple" and "several" is at least two, for example, two, three, etc., unless otherwise clearly and specifically defined.

[0043] See also Figure 1 As shown, the present invention is a foldable baby play safety fence structure, including a rectangular or square upper frame. When the upper frame is assembled, two mutually parallel fence cross bars 1 and two mutually parallel fence cross bars 2 are arranged into a rectangular or square shape, and articulated joints 4 are used to connect the fence cross bars 1 and the fence cross bars 2 2 at the four corners. Finally, support leg rods 3 are installed at the bottom ends of the corresponding articulated joints 4 to facilitate the overall assembly of the safety fence structure of the present application.

[0044] In order to realize the folding function of the safety fence structure of the present application, during the design, the articulated joint 4 and the leg rod 3 are kept locked or unlocked through the unlocking mechanism 1 5; the fence cross bar 2 is divided into the rod 3 20 and the rod 4 21 that can be folded, one end of the rod 3 20 and the rod 4 21 are fixedly connected to the articulated joint 4, and the other end is kept locked or unlocked through the unlocking mechanism 2 6; the fence cross bar 1 is divided into the rod 1 10 and the rod 2 11 that can be folded, one end of the rod 10 and the rod 2 11 are fixedly connected to the articulated joint 4, and the other end is kept locked or unlocked through the unlocking mechanism 3 7.

[0045] In order to make the folding process of the safety fence structure of the present application possible, three unlocking mechanisms are designed to perform the folding operation, thereby solving the problem of accidental folding and closing of most parts of the joints in an active state, thereby ensuring the safety of the safety fence structure.

[0046] When the safety fence structure of this application is in the unfolded state, if Figure 1 As shown, when the unlocking mechanism 1 5 keeps the leg rod 3 and the articulated joint 4 locked and connected, the leg rod 3 is vertically arranged at the four corners of the upper frame; when the unlocking mechanism 2 6 keeps the rod 3 20 and the rod 4 21 locked and connected, the rod 3 20 and the rod 4 21 are horizontally aligned; when the unlocking mechanism 3 7 keeps the rod 10 and the rod 2 11 locked and connected, the rod 10 and the rod 2 11 are horizontally aligned.

[0047] When the safety fence structure of this application is in the first folded state, if Figure 2 As shown, when the unlocking mechanism 1 5 keeps the leg rod 3 and the joint 4 unlocked, the leg rod 3 rotates along the joint 4 toward the fence crossbar 2 2 and closes; when the unlocking mechanism 1 5 is designed, as shown in FIG. Figure 5 As shown, the unlocking mechanism 5 includes a shorting rod 50 and an unlocking slider 52. The bottom of the shorting rod 50 is inserted and connected to the top end of the leg rod 3, and the top is rotatably connected to the adapter 41 of the articulated joint 4. The hollow inner cavity of the shorting rod 50 is slidably connected to the unlocking slider 52. The unlocking slider 52 is provided with an unlocking slide button 53 of an integrated structure. The unlocking slide button 53 is inserted and connected in the outer avoidance slide hole 30 and the inner avoidance slide hole 51. The inner avoidance slide hole 51 is opened on the side wall of the shorting rod 50, and the outer avoidance slide hole 30 is opened on the side wall of the leg rod 3. The bottom end of the adapter 41 is provided with a lock groove 410 for being inserted and connected to the unlocking slider 52; the articulated joint 4 is provided with two sleeve parts 40 with a right corner structure, one sleeve part 40 is used to sleeve and connect to the fence cross bar 1, and the other sleeve part 40 is used to sleeve and connect to the fence cross bar 2.

[0048] When the unlocking mechanism 5 of the present application is in use, the unlocking slide button 53 slides upward along the outer wall of the leg rod 3 and the short-circuit rod 50. At this time, the unlocking slider 52 drives the unlocking slider 52 to move upward along the hollow inner cavity of the short-circuit rod 50 until the unlocking slider 52 is inserted and locked in the locking groove 410 of the adapter 41. It should be understood that there is a friction limiting effect between the unlocking slide button 53, the unlocking slider 52 and the short-circuit rod 50, so that the articulated joint 4, the short-circuit rod 50 and the leg rod 3 are locked to keep the leg rod 3 vertically arranged; on the contrary, when the unlocking slider 52 slides downward, the unlocking slider 52 is disengaged from the locking groove 410 and the leg rod 3 can be rotated along the articulated joint 4 through the short-circuit rod 50 to realize the rotation and folding of the leg rod 3 along the articulated joint 4 toward the fence cross bar 2, thereby completing the first folding operation.

[0049] When the safety fence structure of this application is in the second folding state, if Figure 3 As shown, when the unlocking mechanism 2 6 keeps the rod 3 20 and the rod 4 21 unlocked and connected, the rod 3 20 rotates along the unlocking mechanism 2 6 toward the rod 4 21 and closes; when the unlocking mechanism 2 6 is designed, as shown Figures 6 to 9 As shown, the unlocking mechanism 2 6 includes a joint block 60 and an unlocking push block 1 61. The unlocking push block 1 61 is vertically slidably connected to the joint block 60. When the unlocking push block 1 61 is at the bottom position, the unlocking push block 1 61 and the locking block 1 203 remain in contact and locked; when the unlocking push block 1 61 moves upward along the joint block 60, the unlocking push block 1 61 guides the locking block 1 203 to slide into the corresponding rod 3 20 or rod 4 21, and the locked connection position between the rod 3 20 or rod 4 21 and the joint block 60 is unlocked.

[0050] When designing the unlocking push block 61, a connecting pin 5 611 is inserted at the top of the unlocking push block 61, and the pin 5 611 is slidably connected to the upper pin sliding hole 603 on the joint block 60, and the sliding hole 3 613 opened at the bottom end of the unlocking push block 61 is slidably connected to the pin 612, and the pin 612 is connected to the positioning pin hole 2 604 on the joint block 60; and the top surface of the unlocking push block 61 is provided with a guide inclined surface 1 610 with a conical structure, and the guide inclined surface 1 610 is used for guiding and interfering with the locking block 203.

[0051] When the locking block 203 is designed, a sliding hole 205 is provided at the end of the locking block 203 away from the unlocking push block, and the sliding hole 205 is slidingly connected to the pin column 3 200, and the rod 3 20 or the rod 4 21 is inserted and connected with the positioning pin hole 1 600 on the joint block 60 through the pin column 3 200, and the inner cavity of the locking block 203 is elastically connected to the pin column 3 200 through the spring 1 204, and a connecting pin column 4 201 is inserted on the locking block 203, and the pin column 4 201 is slidingly connected to the sliding hole 1 202 on the rod 3 20 or the rod 4 21, and the pin column 4 201 is guided and slidably connected to the arc-shaped pin hole 601 on the joint block 60; the top of the arc-shaped pin hole 601 is provided with a locking pin hole 602 for locking the connecting pin column 4 201.

[0052] During the use of the unlocking mechanism 26 of the present application, the rod 3 20 and the rod 4 21 are symmetrically arranged on both sides of the joint block 60, and the locking block 1 203 is designed in the rod 3 20 and the rod 4 21, and the connection method between the two and the joint block 60 is the same. For example, when the fence crossbar 22 is in the unfolded state, the rod 3 20 and the rod 4 21 are horizontally aligned. At this time, the locking block 1 203 extends out under the action of the spring 1 204 and contacts and locks with the guide inclined surface 1 610 on the unlocking push block 1 61. The pin column 5 611 connected to the unlocking push block 1 61 is located at the lowest end of the upper pin column sliding hole 603, and the pin column 612 connected to the joint block 60 is located at the sliding hole 3 6 At the highest end of 13, pin four 201 moves upward along the arc-shaped pin hole 601 until it is locked in the locking pin hole 602, so that the rod three 20 and the rod are securely locked horizontally; on the contrary, when the unlocking push block 1 61 is manually moved upward, the guide inclined surface 1 610 of the unlocking push block 1 61 guides and presses the locking block 1 203, so that the locking block 1 203 slides telescopically into the rod three 20 and the rod four 21 respectively, and the pin four 201 moves along the sliding hole 1 202, and the pin four 201 disengages from the locking pin hole 602 and moves downward along the arc-shaped pin hole 601, so that the rod three 20 rotates and closes to the rod four 21 along the unlocking mechanism 2 6, thereby completing the second folding operation.

[0053] When the safety fence structure of this application is in the third folding state, if Figure 4 As shown, when the unlocking mechanism 3 7 keeps the rod 10 and the rod 2 11 unlocked and connected, the rod 10 rotates along the unlocking mechanism 3 7 toward the rod 2 11 and closes; when the unlocking mechanism 3 7 is designed, as shown in FIG. Figures 10 to 13As shown, the unlocking mechanism 3 7 includes a joint sleeve 1 70 and a joint sleeve 2 71. The joint sleeve 2 71 is sleeved and connected to the rod 2 11.

[0056] When the unlocking mechanism 3 7 of the present application is in use, when the fence crossbar 1 is in the unfolded state, the rod 10 and the rod 2 11 are horizontally aligned. At this time, the locking block 2 74 is extended under the action of the spring 2 75, and the locking block 2 74 is locked and plugged with the locking groove 2 711. The guide bevel 3 740 on the locking block 2 74 contacts and locks with the guide bevel 2 730 on the unlocking push block 2 73.
