[0020] 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.

[0021] 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.

[0022] This embodiment mainly describes a structure for preventing round bars from loosening in a children's gate, as follows:

[0023] like Figures 1 to 4 As shown, a structure for preventing round rods from loosening of a child door fence comprises an upper door beam 1, a lower door beam 2 and a round rod 3. The upper door beam 1 and the lower door beam 2 are arranged parallel to each other. The round rod 3 is arranged between the upper door beam 1 and the lower door beam 2. The upper door beam 1 and the lower door beam 2 are provided with mounting holes 4 for mounting the round rod 3. The two ends of the round rod 3 are respectively connected to the upper door beam 1 and the lower door beam 2 through the mounting holes 4, and then are surrounded by the upper door beam 1 and the lower door beam 2 to form a door fence. In order to improve the stability of the door fence, elastic sleeve caps 5 are provided at both ends of the round rod 3. When installed, the two ends of the round rod 3 are respectively extended into the upper door beam 1 and the lower door beam 2. In the mounting holes 4 of the beam 1 and the lower door beam 2, the outer surface and inner surface of the cap 5 are closely attached to the inner wall of the mounting hole 4 and the outer wall of the round rod 3 respectively, and the gap between the mounting hole 4 and the round rod 3 is filled, so that the round rod 3 will not shake relative to the upper door beam 1 and the lower door beam 2, which can avoid the deviation of the accuracy of the mounting hole 4 or the need for installation tolerance during the production process. There is a gap between the round rod 3 and the mounting holes 4 in the upper door beam 1 and the lower door beam 2, which causes the round rod 3 to rotate and shake, and the problem of abnormal noise when touched, resulting in a poor user experience. After installation, the cap 5 completely wraps the end of the round rod 3 inside, and the opening of the cap 5 has a brim extending out of the mounting hole 4, and the opening of the mounting hole 4 is wrapped by the cap 5 to fill the gap. The design of the cap 5 not only solves the problem of the rotation and shaking of the round rod 3, but also can realize the detachable connection of the door railing, reduce the packaging size and reduce the transportation cost.

[0024] Specifically, the shape of the cap 5 matches the shape of the mounting hole 4 and the insertion parts at both ends of the round rod 3. The mounting hole 4 can be circular, rectangular, polygonal, or special-shaped, and the two ends of the round rod 3 can also be other shapes that match it, such as a cylinder, a rectangular cylinder, a polygonal body, a special-shaped cylinder, etc. Preferably, the mounting hole 4 is a circular hole, and the round rod 3 is a cylindrical rod whose end matches the circular hole.

[0025] Specifically, the two ends of the round rod 3 are interference fit with the inner wall of the mounting hole 4, which can fill the gap in the mounting hole 4 and press the sleeve cap 5, further improving the stability of the round rod 3 and the upper door beam 1 and the lower door beam 2.

[0026] Specifically, the cap 5 is a cap 5 made of plastic / rubber / silicone material, or a cap 5 made of other materials with good plasticity and elasticity. The plastic cap 5 can be deformed and move to the place with the gap in the installation hole 4 to fill the gap, so as to avoid the existence of the gap affecting the stability of the round rod 3 and the upper door beam 1 and the lower door beam 2 after installation.

[0027] Specifically, the upper door beam 1 and the lower door beam 2 are hollow pipes, which can save raw materials during production. At the same time, during the packaging and transportation process, the hollow pipes are lighter in weight, more convenient to transport and can reduce transportation and delivery costs. The installation hole 4 is an independent hole and is not connected to the pipes inside the upper door beam 1 and the lower door beam 2.

[0028] In the description of the present utility model, it should be noted that the terms "upper", "lower", "front", "back", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, or are the directions or positional relationships in which the utility model product is usually placed when in use.

This article uses specific examples to illustrate the principle and implementation method of the utility model. The description of the above embodiments is only used to help understand the utility model and the core idea. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified. These improvements and modifications also fall within the scope of protection of the claims of the utility model.
