DETAILED DESCRIPTION

[0024] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are only descriptive and exemplary and should not be construed as limiting the protection scope of the present invention.

[0025] It should be noted that like reference numerals denote similar items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0026] This embodiment mainly describes a structure of an extension piece of a child gate fence, as follows:

[0027] like Figures 1 to 5As shown, an extension structure of a child gate fence includes an upper crossbeam 1, a lower crossbeam 2, a plurality of column assemblies 3 and fasteners 5 for detachably connecting the plurality of column assemblies 3 to the upper crossbeam 1 and the lower crossbeam 2. The upper crossbeam 1 and the lower crossbeam 2 are arranged parallel to each other, and both ends of the column assemblies 3 are detachably connected to the upper crossbeam 1 and the lower crossbeam 2. Specifically, the upper crossbeam 1 and the lower crossbeam 2 are provided with a plurality of mounting holes 6 on opposite sides, and the upper crossbeam 1 and the lower crossbeam 2 are provided with a plurality of operating holes 4 on the back sides. The mounting holes 6 correspond to the operating holes 4 one by one, and the operating holes 4 are connected to the mounting holes 6. When the operating holes 4 are used for installation, it is convenient for tools to be inserted and fixed for use. For the convenience of installation, the aperture of the operating hole 4 is larger than the aperture of the mounting hole 6. The two ends of the column assemblies have threaded holes 33, and the fasteners 5 are fasteners that cooperate with the threaded holes 33. When installing, the threaded holes 33 at both ends of the column assembly 3 correspond to the mounting holes 6 of the upper beam 1 and the lower beam 2 respectively, the fastening screws are inserted through the operating holes 4, and the fasteners 5 are passed through the mounting holes 6 and extended into the threaded holes 33 through the installation tool, so that the two ends of the column assembly 3 are detachably connected to the upper beam 1 and the lower beam 2 respectively, and the upper beam 1, the lower beam 2 and the column assembly 3 are connected with the screws to form an extension of the children's gate. When the extension needs to be disassembled, the tool is inserted from the operating hole 4, and the fastening screws in the upper beam 1 and the lower beam 2 are all taken out by the tool. The lower beam 2 of the extension can be removed, and the upper beam 1 and the column assembly 3 can be independently disassembled. The extension is designed as a detachable structure, which can reduce the packaging size and transportation cost on the basis of the existing gate.

[0028] like Figure 3 As shown, the column assembly 3 includes a tubular column 31 and a connecting column 32 plugged on both sides of the column 31 and fixedly connected to the column 31. The connecting column 32 can be plugged into the column 31 for interference fit, or can be fixed by welding. In this solution, the connecting column 32 and the column 31 are fixed by welding, and a threaded hole 33 is provided on the connecting column 32. The fastening screws are threadedly connected to the column 31 on both sides of the column 31 to fix the two ends of the column 31 to the upper beam 1 and the lower beam 2 respectively. After the two ends of the column 31 are fixed on the upper beam 1 and the lower beam 2, the nut of the fastening screw is located in the upper beam 1 and the lower beam 2 and the bottom of the nut rests on the inner wall of the beam around the mounting hole 6.

[0029] like Figure 3As shown, the upper crossbeam 1 and the lower crossbeam 2 are hollow tubes, and both sides of the upper crossbeam 1 and the lower crossbeam 2 are plugged with heads 7, and a receiving channel 71 is provided in the head 7. The receiving channel 71 of the head 7 on one side of the upper crossbeam 1 and the lower crossbeam 2 is provided with a top rod 8 that can be extended and abutted against the wall. The top rod 8 is provided with an external screw, and the knob 81 has an internal thread that cooperates with the external thread. The top rod 8 is provided with a knob 81, and the knob 81 cooperates with the top rod 8 thread. One end of the top rod 8 extends into the receiving channel 71 and is connected or slidably connected with the receiving thread. When it is a sliding connection, the receiving channel 71 and the top rod 8 have friction so that the top rod 8 will not slide left and right when no force is applied. The outer end of the top rod 8 has a supporting plate 82 that abuts against the wall. The top rod 8 can be extended / retracted back to the receiving channel 71 and abut against or away from the wall by rotating the knob 81 forward and reversely. A connector 9 connected to the gate is provided in the receiving channel 71 in the end cap 7 on the other side of the upper crossbeam 1 and the lower crossbeam 2. The connector 9 may be a threaded column threadedly connected to the gate, or a latch inserted into the gate, or the connector 9 may be a connecting rod 91 having the same structure as the above-mentioned top rod 8. A knob 81 is threadedly connected to the side of the connecting rod 91 close to the gate, and a stop plate 92 is provided at one end of the connecting rod 91 located in the upper crossbeam 1 and the lower crossbeam 2 to prevent the connecting rod 91 from completely sliding out. The knob 81 may be rotated forward and backward to extend / retract the connecting rod 91 back into the receiving channel 71 and extend into the gate or away from the gate. The connecting rod 91 drives the stop plate 92 to slide in the upper crossbeam 1 and the lower crossbeam 2 during the extension and retraction process. When the top rod 8 is extended outward, the stop plate 92 abuts against the end of the search channel for the maximum length of the connecting rod 91.

[0030] Specifically, in order to prevent the mounting holes 6 of the upper beam 1 and the lower beam 2 from being exposed and affecting the visual sense and easily accumulating dust and dirt, an elastic sealing cap 10 is provided at each operating hole 4 to seal the operating hole 4. The sealing cap 10 is provided with a barb 101. When the sealing cap 10 is covered on the operating hole 4, the barb 101 is hooked on the inner walls of the upper beam 1 and the lower beam 2. Once the sealing cap 10 is installed, it is not easy to fall off.
