BACKGROUND

1. Technical Field

The present invention relates to the technical field of daily life, specifically to a bed frame connecting structure and a bed frame.

2. Background Information

In modern society, folding beds are flexible to use, and occupy a small space when not in use. They are favored by a large amount of consumers because during use, a folding bed frame is unfolded and quickly assembled with other auxiliary horizontal rod components into a bed frame, meeting the user's need.
Conventional mounting of existing bed frames typically involves using screws to secure connecting rods, resulting in a complex structure with cumbersome assembly steps. Additionally, such mounting also includes assembly through an insertion method, where a square insertion tab is fitted with and fixed in a square insertion slot. In this insertion process, a gap is inevitably present between the insertion tab and the insertion slot, causing wobbling and poor stability.
In view of this, the applicant has conducted in-depth research on the above problems, which led to the creation of the present invention.

DETAILED DESCRIPTION OF THE DRAWINGS AND THE PRESENTLY PREFERRED EMBODIMENTS

The present invention is further described below with reference to the drawings and specific embodiments.

Embodiment 1

As shown in FIGS. 1 and 2 , this embodiment provides a bed frame connecting structure, including a support leg 10 and a connecting rod 20. The outer contour of the cross section of the support leg 10 is in the shape of a right-angle sector, and the connecting rod 20 is a conventional square rod. One end of the connecting rod 20 is fixedly connected to a connector, and the specific fixed connection method between them may be a conventional method such as welding or bonding. In this embodiment, the fixed connection method is described using welding as an example. A clamping member is fixedly connected to the side wall of the support leg 10. The support leg 10 and the connecting rod 20 are fixed together through the fitting of the connector and the clamping member, without any bolt, making the structure simple and easy to assemble and disassemble.
The clamping member includes a first side plate 21, a second side plate 22, a third side plate 23, and a fourth side plate 24. The first side plate 21 is opposite the fourth side plate 24, the first side plate 21 and the fourth side plate 24 are both connected fixedly or integrally to one of side walls of the support leg 10, the second side plate 22 is connected fixedly or integrally to a side of the first side plate 21 away from the support leg 10, and the third side plate 23 is connected fixedly or integrally to a side of the fourth side plate 24 away from the support leg 10. A side of the second side plate 22 away from the first side plate 21 and a side of the third side plate 23 away from the fourth side plate 24 are connected fixedly or integrally, and the second side plate 22 and the third side plate 23 form an acute angle. The first side plate 21, the second side plate 22, the third side plate 23, the fourth side plate 24, and the side wall of the support leg 10 jointly enclose an insertion slot 25 that communicates vertically. An outer contour of a cross section of the insertion slot 25 is pentagonal. The connector includes a first connector and a second connector that are connected integrally. The second connector includes a first plate, second plates fixedly connected in one-to-one correspondence to two sides of the first plate, and third plates fixedly connected in one-to-one correspondence to sides of the second plates away from the first plate. The first plate, the two second plates, and the two third plates jointly enclose a hollow insertion portion 28. The first connector is fixedly connected to an end of the connecting rod 20, and the insertion portion 28 is inserted into the insertion slot 25. An outer peripheral surface of the insertion portion 28 closely fits with an inner side surface of the insertion slot 25, and an outer contour of a cross section of an opening of the insertion slot 25 remains unchanged. The first side plate 21, the second side plate 22, the third side plate 23, and the fourth side plate 24 gradually decrease in dimension from one end facing the connecting rod 20 to the other end. This ensures that the bed frame connecting structure, when subjected to external omnidirectional pressure, can go lower, fit tighter, and be inserted more firmly, thereby ensuring a smaller gap between the support leg 10 and the connecting rod 20, further improving the stability of the connection.
The first connector includes a connecting plate 27 and limiting plates 26 fixedly connected in one-to-one correspondence to two sides of the connecting plate 27. The connecting plate 27 and the two limiting plates 26 jointly enclose a positioning groove, and an end of the connecting rod 20 is fixed and connected through insertion in the positioning groove, ensuring the stability of the connecting rod 20 and the first connector.
In the present invention, the first side plate 21, the second side plate 22, the third side plate 23, and the fourth side plate 24 are arranged with the dimension gradually decreasing from one end facing a connecting rod to the other end, and fit with each other to form a wedge-shaped insertion slot 25. The support leg 10 and the connecting rod 20 are fixed together through fitting between the insertion portion 28 and the wedge-shaped insertion slot 25. When subjected to external omnidirectional pressure, the insertion portion can go lower and fit tighter, making the gap smaller without wobbling, thus allowing for a simple structure with good stability.
