Description

Technical Field

[0001] This utility model belongs to the field of folding bed technology, and specifically relates to a rod connector and a folding bed frame. Background Technology

[0002] Folding beds, also known as camp beds, evolved from folding chairs in their three-dimensional folding structure, generally consisting of a mattress fabric and a frame. When the mattress fabric bears weight, it deforms significantly due to inward pulling forces, affecting lying comfort. Product iterations have led to increasingly rational structural designs, such as:

[0003] CN202120289645.7 discloses a folding bed support frame, such as... Figure 7 The structure comprises four facades: two ends and two sides. Each facade contains a group of diagonal rods formed by the intersection and hinge of two diagonal rods. The upper and lower ends of the diagonal rod groups are hinged to each other to form a whole. The two side facades contain two groups of diagonal rods, which are hinged together by upper and lower corner plates in the middle. At the intersection and hinge point of the two diagonal rods in each group, a vertical rod is movably positioned by a sliding sleeve. The upper end of the vertical rod is hinged to a connecting plate, and a horizontal rod is hinged to each of the two horizontal directions of the connecting plate. The other end of the horizontal rod is hinged to the upper corner plate of the same side facade. The lower end of the vertical rod has a bent section that faces inward toward the bed, with the end of the bent section extending to the inside of the orthographic projection of the two diagonal rods at the intersection and hinge point. This structure cleverly utilizes the bent section of the vertical rod to shift the point of force on the ground toward the inside of the bed, thereby increasing the torque to counteract the torque of the weight-bearing force of the mattress fabric, but the overall structure is not harmonious.

[0004] The object of this invention is to find a more reasonable technical solution. Summary of the Invention

[0005] The purpose of this invention is to design a rod connector that enables a stable foldable connection between two rods, and to design a folding bed frame using this connector.

[0006] The technical solution of this utility model is implemented as follows: a rod connecting seat, characterized in that: the connecting seat has an assembly hole for inserting a rod and an opening slot for accommodating the rod, and a rivet hole through the assembly hole and the opening slot is provided, the rod is positioned by means of the rivet hole, and the rod positioned on one side of the opening slot can be folded and unfolded relative to the connecting seat.

[0007] The connecting seat assembly hole and the opening groove have an overlapping section. The rivet hole of the opening groove is close to one end of the assembly hole opening, and the angle between the axis of the opening groove and the axis of the rivet hole is between 80 and 88 degrees. When the rod is unfolded into place, it abuts against the groove wall of the opening groove to eliminate the gap.

[0008] The connecting seat opening groove is located above the assembly hole, distributed vertically, and the opening groove communicates with the assembly hole at the rivet hole end.

[0009] The connecting seat also has a riveting position for positioning the third rod on the side away from the opening slot.

[0010] A folding bed frame includes four facades at both ends and two sides. Each facade contains a diagonal rod group formed by two diagonal rods intersecting and hinged together. The upper and lower ends of the diagonal rod groups are hinged to each other to form a foldable whole. The two side facades each contain two diagonal rod groups, which are hinged together by upper and lower corner plates in the middle. At the intersection and hinge point of the two diagonal rods in each diagonal rod group, a vertical rod is movably positioned by a sliding sleeve. A rod connecting seat as described above is hinged to the upper end of the vertical rod. The characteristic feature is that a horizontal rod is hinged to both the mounting hole and the opening slot of the connecting seat, and the other end of the horizontal rod is hinged to an upper corner plate at the far end of the same side facade.

[0011] Furthermore, the end of the crossbar hinged to the mounting hole of the connecting seat has a bent section, and the rest is flush with the working surface of the other crossbar on the same side.

[0012] This utility model features a unique design, simple structure, stable rod connection, and seamless unfolding. The connecting seat not only provides a foldable connection for two rods without requiring extra actions, but also provides a riveting position for a third rod, exhibiting excellent expandability. Using this connecting seat as a foldable connection for the two crossbars of a folding bed frame can effectively overcome the defect of mattress fabric shrinking inward under stress, and the appearance is not obtrusive.

[0025] Reference Figures 1 to 4 A connecting seat 1 for rods has a mounting hole 11 and an opening slot 12. The mounting hole 11 is for inserting and positioning one rod, and the opening slot 12 can accommodate another rod and allows the rod to fold and unfold. That is, the two rods can be unfolded and folded relative to each other, and the included angle between the unfolding and folding of the two rods is designed according to different usage scenarios. For this purpose, the connecting seat 1 has a rivet hole 13 that passes through the mounting hole 11 and the opening slot 12, and the rivet hole 13 facilitates the insertion of rivets to position the rods.

[0026] As a preferred embodiment, the mounting hole 11 and the opening groove 12 of the connector have an overlapping section, the rivet hole 13 of the opening groove 12 is close to one end of the opening of the mounting hole 11, and the angle X between the axis of the opening groove 12 and the axis of the rivet hole 13 is between 80 and 88 degrees. Figure 3 When the rod is fully extended, it abuts against the wall of the opening slot 12 to eliminate gaps. The rivet hole 13 on the opening slot 12 is offset at one end of the assembly hole 11. When the rod is fully extended, it can be partially supported by the opening slot, and the slightly inclined wall of the opening slot 12 abuts against the rod to eliminate gaps and ensure the stability of the two rods in use.

[0027] Furthermore, the connecting seat opening slot 12 is located above the mounting hole 11, arranged vertically, and the opening slot 12 communicates with the mounting hole 11 at the rivet hole 13 end. This connection position avoids creating space for the folding and swinging of the rod. While the vertical arrangement of the opening slot 12 and the mounting hole 11 is preferred, it reduces the width space required and facilitates downward load transfer; however, a horizontally arranged design is not excluded to meet different usage scenarios.

[0028] In addition, the connecting seat 1 is provided with a riveting position 14 for positioning a third rod on the side away from the opening slot 12, which can be used to position the load-bearing support rod or to fold the connection of three rods, thus enriching the uses of the connecting seat.

[0029] The following is an application example of connector 1 on a folding bed frame.

[0030] Reference Figure 5 and Figure 6The folding bed frame includes four facades at both ends and on both sides. Each facade contains a diagonal rod group 2 formed by two diagonal rods intersecting and hinged together. The upper and lower ends of the diagonal rod group 2 are hinged to each other to form a foldable whole. The two side facades each contain two diagonal rod groups 2, which are hinged together by the upper corner plate 3 and the lower corner plate 4 in the middle. At the intersection and hinge point of the two diagonal rods in each diagonal rod group 2, a vertical rod 5 is movably positioned by a sliding sleeve 21. A connecting seat 1 is hinged to the upper end of the vertical rod 5. Two horizontal rods 6 are hinged to the connecting seat 1. Specifically, the vertical rod 5 is hinged to the hinge position 14 of the connecting seat. A horizontal rod 6 is hinged to the assembly hole 11 and the opening slot 12 of the connecting seat. The other end of the horizontal rod 6 is hinged to an upper corner plate 3 at the far end of the same side facade. By using the connecting seat 1 to eliminate the gap between the two crossbars 6, it is equivalent to the effect of a single rod, overcoming the defect of the existing folding bed frame where the hinges are severely recessed after the mattress fabric bears the weight, while maintaining a harmonious appearance.

[0031] Furthermore, the end of the crossbar 6 hinged to the mounting hole 11 of the connecting seat has a bent section 61, and the rest is flush with the working surface of the other crossbar 6 on the same side. The bent section 61 eliminates the height difference caused by the vertical distribution of the mounting hole 11 and the opening slot 12; similarly, the mounting hole 11 and the opening slot 12 on the connecting seat can also be distributed horizontally. In this case, a crossbar 6 needs to form a bent section on the horizontal plane.

[0032] The terms "upper and lower" and "horizontal plane" mentioned above refer to the folding bed frame in use. The connecting seat 1 is also described from the perspective of the folding bed frame in use, and does not affect the use of the connecting seat as a foldable support for sunshades, tents, etc.
