Fig.11 The sixth mounting hole 3211 , the seventh mounting hole 3212 , the eighth mounting hole 3221 and the ninth mounting hole 3222 are all used for fixed connection with the corresponding first connecting rod 11 or second connecting rod 21 .

[0099] The number of the third fixing members 325 and the number of the fourth fixing members 326 are both four.

[0100] The third fixing member 325 , the fourth fixing member 326 , and the fifth fixing member 327 are all screws.

[0101] Both ends of the first connecting rod 11 are connected to the corresponding upper connecting mechanism 31 and the lower rotating mechanism 32 through a snap-fit ​​structure F. Fig.14 and Fig.15 Both ends of the second connecting rod 21 are also connected to the corresponding upper connecting mechanism 31 and the lower rotating mechanism 32 through a snap-fit ​​structure F (not shown in the figure).

[0102] The fast folding child fence device 1 provided in the present application has a first limiting structure A1 on the connecting spring body 311 of the upper connecting mechanism 31, and a second limiting structure A2 on the rotating bracket assembly 312 of the upper connecting mechanism 31. The splicing and fixing effect and the folding and storage effect of the fast folding child fence device 1 are achieved through the connection and separation of the first limiting structure A1 and the second limiting structure A2. Please refer to the folding state of the fast folding child fence device 1 Fig.16 and Fig.17 The two limiting structures are used in combination to increase the firmness of the fence device. Moreover, the present application only needs to move the connecting pop-up body 311 to switch the unlocking state and the locking state of the upper connecting mechanism 31, thereby simplifying the steps for users to fold the fence device and improving the convenience of folding.

[0103] The upper connecting mechanism 31 of the present application adopts a spring-loaded unlocking disassembly and assembly method, and the lower rotating mechanism 32 adopts a mechanical shaft 324 folding method. The combination of these two methods can increase the structural reliability of the quick-folding child fence device 1 and the convenience of folding.

[0104] The installation method of the quick-folding child fence device 1 of the present application can be implemented according to the following examples:

[0105] Four first connecting rods 11, two three-way connecting pieces 12, four second connecting rods 21 and six upper connecting mechanisms 31 are connected to form a square upper frame assembly E1; six first connecting rods 11 and eight second connecting rods 21 are used as intermediate pieces E2; four first connecting rods 11, two three-way connecting pieces 12, four second connecting rods 21 and six lower rotating mechanisms 32 are connected to form a square lower frame assembly E3; during assembly, the intermediate piece E2 is assembled to the upper frame assembly E1, and then the lower frame assembly E3 is assembled to the upper frame assembly E1 and the intermediate piece E2, see Fig.18 The installation method is not limited to Fig.18 Alternatively, you can assemble each piece first and then connect each piece one by one.

[0106] The technical features of the above embodiments can be combined without changing the basic principles of the present invention. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0107] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the scope of patent protection of the present application shall be subject to the attached claims.
