Technical Field

[0001] The utility model relates to the technical field of children's fences, and more particularly to a children's fence with adaptive activity areas. Background Art

[0002] Child fences are tools made of plastic, metal or wood that are used to limit children's range of activities or isolate dangerous areas. They can help parents better supervise and control their children's range of activities, provide a relatively safe environment for children, and allow children to play freely without getting hurt. Therefore, child fences play an important protective role in helping children grow up.

[0003] A child fence is generally composed of a series of foldable panels or several independent panels. The Chinese patent with publication number CN220024636U and patent name "A Children's Play Fence" discloses a foldable child fence. The support rods and the supporting rods are all designed with movable hinges. When in use, the upper and lower frames can be unfolded for use. When not in use, the first upper support rod and the second upper support rod need only be pulled upward to fold the fence into a bundle, which is convenient for storage and transportation without disassembly.

[0004] Although the above-mentioned foldable child fence is convenient for storage and carrying, it has some limitations. That is, the size of the enclosed area is often fixed and cannot meet the needs of use in different places. Moreover, the fixed area size may not be able to adapt to the needs of children's continuous growth. Children are prone to feel restricted in their activities, which affects their desire to explore.

[0031] The utility model is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] In the description of the present utility model, it should be noted that the terms "upper", "lower", "left", "right", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, or the directions or positional relationships in which the utility model product is usually placed when in use. They are only for the convenience of simplifying the description, and do not indicate or imply that the directions are specific directions that must be possessed and specific directions, structures, and operations, and therefore should not be understood as limitations on the present utility model.

[0033] This embodiment is as follows: Figures 1 to 6As shown, the utility model relates to a child fence with an adaptive activity area, which includes a front panel 1, a rear panel 2, a front guide rod 3, a rear guide rod 4 and a locking assembly. The front guide rod 3 and the rear guide rod 4 are stacked up and down in space, and their respective opposite ends are connected to the opposite sides of the front panel 1 and the rear panel 2 respectively. More specifically, a spacing position is formed between the front guide rod 3 and the rear guide rod 4 and the connected front panel 1 and the rear panel 2. The locking assembly includes a spring buckle 5 and a sliding buckle 6. The spring buckle 5 has an inner cavity 501, and the inner cavity 501 has an opening. Due to the existence of the spacing position between the front guide rod 3 and the front panel 1, the spring buckle 5 can be sleeved on the free end of the front guide rod 3 through the inner cavity 501. A return groove 502 connected to the inner cavity 501 is opened on any side wall of the spring buckle 5. It should be mentioned that the return groove There is no particular restriction on the shape of 502. Here, a spring buckle 5 having a return groove 502 along the length direction of the inner cavity 501 is taken as an example. A spring piece 503 is formed on one side wall of the return groove 502. The spring piece 503 can be deflected toward the inner cavity 501 by pressing, and returns to its original position after the applied force is removed. In order to save more effort when pressing the spring buckle 5, the spring piece 503 has an end as a fixed end and extends along the length direction of the return groove 502. The slide buckle 6 has an upper groove 601 and a lower groove 602 that are opposite to each other. The lower groove 602 is used to be sleeved on the rear guide rod 4 so that it can slide along the rear guide rod 4. The upper groove 601 is opposite to the spring buckle 5 along the moving path of the slide buckle 6 along the rear guide rod 4, and the spring buckle 5 can be inserted when sliding. A pressing hole connected to the upper groove 601 is provided on the side wall of the slide buckle 6. The spring piece 503 of the spring buckle 5 is embedded in the pressing groove 603. In the embedded state, the spring piece 503 and the outer wall of the pressing groove 603 are matched with the groove wall of the pressing groove 603 to limit the horizontal movement of the sliding buckle 6. Because the spring piece 503 can be deflected toward the inner cavity 501 of the spring buckle 5 under pressure, the spring piece 503 can be separated from the docking with the pressing groove 603 when it is deflected under pressure, thereby releasing the restriction of the outer wall of the spring piece 503, so that the sliding buckle 6 can slide freely along the extension direction of the rear guide rod 4. The child fence of the utility model can expand or contract any length by controlling the front panel 1 and the rear panel 2 to move toward and away from each other. The user can independently determine the expansion or contraction size according to factors such as the size of the space and the required activity range of the child to form an adaptive activity area. , so that the final enclosed activity area can meet diverse usage requirements. When the front panel 1 and the rear panel 2 are expanded and retracted, the spring buckle 5 and the sliding buckle 6 of the locking assembly move with the front panel 1 and the rear panel 2 respectively. After the size adjustment is completed, the sliding buckle 6 can be moved along the rear guide rod 4 toward the spring buckle 5 to approach the spring buckle 5 and use the spring piece 503 of the spring buckle 5 to be plugged and fixed with the pressing groove 603 of the sliding buckle 6 to keep the front panel 1 and the rear panel 2 in the adjusted state, effectively avoiding the relative movement of the front panel 1 and the rear panel 2 caused by accidental force, and improving the stability of the final enclosed activity area. The spring buckle 5 and the sliding buckle 6 are detachable. You only need to press the spring piece 503 to deflect it toward the inner cavity 501 of the spring buckle 5 and disengage it from the docking with the pressing groove 603 to release the fixed state of the sliding buckle 6.The operation of adjusting the expansion and contraction size of the front panel 1 and the rear panel 2 is simple and convenient, and does not take a long time, which significantly improves the convenience of use. In addition, the front panel 1 and the rear panel 2 can be retracted so that they can be folded and stored when they need to be carried.

[0034] like Figures 2 to 6 As shown, a pressing cap 503a is formed on the spring piece 503, and the spring piece 503 is embedded in the pressing groove 603 through the pressing cap 503a. Overall, the pressing cap 503a is a protruding structure on the outer wall of the spring piece 503, so that the spring piece 503 and the sliding buckle 6 can be plugged into the pressing groove 603 when the spring buckle 5 and the sliding buckle 6 move to relative positions.

[0035] like Figure 3 , Figure 5 and Figure 6 As shown, an inner bevel 601a is formed at the entrance end of the upper slot 601 near the spring buckle 5, and an outer bevel matching the inner bevel 601a is formed on the pressing cap 503a. Since the pressing cap 503a on the spring sheet 503 is a convex structure, based on the above arrangement, when the sliding buckle 6 moves toward the spring buckle 5 until the outer bevel of the pressing cap 503a contacts the inner bevel 601a of the upper slot 601, with further movement, the pressing cap 503a can be guided by the inner bevel 601a and the outer bevel to press the pressing cap 503a. A part of 03a enters the upper slot 601 to avoid being blocked by the outer wall of the sliding buckle 6 on the side of the upper slot 601, and when the pressing cap 503a and the high position of the upper inclined surface move to relative positions, the upper inclined surface is used to squeeze the pressing cap 503a to make it automatically deflect toward the inner cavity 501 of the spring buckle 5, and after reaching the relative position with the pressing slot 603, it is separated from the upper inclined surface and can be embedded in the pressing slot 603 by its own elastic return, thereby realizing the plug-in with the pressing slot 603.

[0036] like Figure 6 and Figure 7 As shown, the spring buckle 5 is fixed to the front guide rod 3 by a self-tapping screw 7, and the self-tapping screw 7 passes through the spring buckle 5 from the outside to the inside of the front guide rod 3 to achieve fixation. In the utility model, there are two self-tapping screws 7, and the two-point fixation is used to improve the stability of the fixation between the spring buckle 5 and the front guide rod 3.

[0037] like Figure 2 as well as Figures 4 to 6 As shown, a pressure plate 604 is formed on the outer wall of the slide buckle 6, and the pressure plate 604 has a concave folding portion, and the free end of the folding portion extends to the top of the spring piece 503. When the user wants to squeeze the spring piece 503 to deflect it toward the inner cavity 501 of the spring buckle 5, the free end of the folding portion of the pressure plate 604 is pressed to deflect it toward the spring piece 503. After contact, the free end of the folding portion of the pressure plate 604 drives the spring piece 503 to deflect toward the inner cavity 501 side.

[0038] like Figures 4 to 6As shown, the free end of the folded portion is inclined toward the spring sheet 503 and contacts the spring sheet 503, thereby reducing the idle distance when the free end of the folded portion of the pressure plate 604 is pressed, so that the pressing cap 503a of the spring sheet 503 can be directly squeezed to drive the spring sheet 503 to deflect toward the inner cavity 501 of the spring buckle 5.

[0039] like Figure 2 as well as Figures 4 to 6 As shown, a plurality of anti-sliding blocks 604 a are formed on the outer wall of the folding portion. The anti-sliding blocks 604 a are arranged to reduce the possibility of the user's hand slipping when pressing the pressing plate 604 .

[0040] Furthermore, both the spring buckle 5 and the slide buckle 6 are injection molded parts, and the material properties ensure that after the pressure applied to the spring piece 503 of the spring buckle 5 and the pressure plate 604 of the slide buckle 6 is removed, the spring piece 503 and the pressure plate 604 can automatically return to their original positions.

[0041] like Figure 2 , Figure 7 and Figure 8 As shown, a plurality of scale grooves 301 are provided on the outer wall of the front guide rod 3 along its length direction, and a marking component 8 is deflected and connected to the rear guide rod 4, and an insertion rod 801 is provided on the marking component 8. When the marking component 8 is deflected toward the scale groove 301, the insertion rod 801 is inserted into the scale groove 301. The scale groove 301 and the insertion rod 801 inserted therewith facilitate the user to understand the expansion or extension distance of the front panel 1 and the rear panel 2, so that when the child fence of the utility model needs to be rebuilt, the expansion or extension distance can be quickly determined. At the same time, when the insertion rod 801 and the scale groove 301 are in the inserted state, the spring buckle 5 and the sliding buckle 6 that are locked by mutual abutment and cooperation further restrict the movement of the front panel 1 and the rear panel 2.

[0042] like Figure 2 , Figure 7 and Figure 8 As shown, it also includes a plurality of guide members 9, which are concave in shape, and the upper and lower edges of the front panel 1 and the rear panel 2 are embedded in the notches of each guide member 9. Through the setting of the guide members 9, the front panel 1 and the rear panel 2 are prevented from excessive deviation when being stored, carried, unfolded, and telescopically adjusted, thereby ensuring the fit between the front panel 1 and the rear panel 2.

[0043] Combination Figures 1 to 8When the child fence of the utility model is in use, when the locking assembly spring buckle 5 and the sliding buckle 6 on the front guide rod 3 and the rear guide rod 4 are in a separated state, the user can adjust the expansion and contraction size by controlling the front panel 1 and the rear panel 2 to move toward or away from each other. During the adjustment process, the distance between the spring buckle 5 and the sliding buckle 6 changes accordingly. When the size adjustment is completed, the positioning member 8 is first rotated to make its insertion rod 801 buckle into the scale groove 301, and then the sliding buckle 6 is moved toward the spring buckle 5 so that the sliding buckle 6 is close to the spring buckle 5. During the movement, the spring buckle 5 is inserted into the upper groove 601 of the sliding buckle 6, and the spring piece 503 pressing cap 503a is squeezed by the upper inclined surface of the opening end of the upper groove 601 and deflected toward the inner cavity 501 by a certain angle. When it reaches the opposite side of the pressing groove 603, it rebounds toward the pressing groove 603 due to the material properties, and the pressing cap 503a can be embedded in the pressing groove 603 and plugged with the pressing groove 603, thereby realizing the locking of the spring buckle 5 and the sliding buckle 6, so that the front panel 1 and the rear panel 2 maintain the adjusted expansion and contraction positions.

[0044] The above embodiments and descriptions are only for explaining the principle and the best embodiment of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements shall fall within the scope of the present invention to be protected.
