Description

Technical Field

[0001] The utility model relates to the technical field of daily life, in particular to a bed frame connection structure and a bed frame. Background Art

[0002] In modern society, due to the flexible use of folding beds, they occupy little space when not in use, and when in use, the folding bed frame can be unfolded and supplemented with other auxiliary crossbar components to quickly form a bed frame to meet the needs of users. Therefore, they are favored by many consumers.

[0003] The traditional installation of existing bed frames generally uses screws to lock and connect the components, with a relatively complex structure and very cumbersome assembly steps. There is also an existing installation method that is assembled by plugging. This type of plugging method is fixed together through the cooperation of a square insert and a square slot. During the plugging process, there will inevitably be gaps between the insert and the slot, which will cause shaking and relatively poor stability.

[0004] In view of this, the applicant has conducted in-depth research on the above problems, and thus this case has been created. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a bed frame connection structure with a simple structure and relatively good stability.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A bed frame connection structure includes feet and connecting rods. One end of the connecting rod is provided with a connecting member, and a clamping member is fixedly connected to the side wall of the foot. The clamping member includes a first side plate, a second side plate, a third side plate, and a fourth side plate. The first side plate and the fourth side plate are arranged opposite to each other, and both the first side plate and the fourth side plate are fixedly connected or integrally connected to the same side wall of the foot. The second side plate is fixedly connected or integrally connected to the side of the first side plate away from the foot. The third side plate is fixedly connected or integrally connected to the side of the fourth side plate away from the foot. The side of the second side plate away from the first side plate and the side of the third side plate away from the fourth side plate are fixedly connected or integrally connected. An acute angle is formed between the second side plate and the third side plate. The first side plate, the second side plate, the third side plate, the fourth side plate, and the side wall of the foot together enclose a vertically penetrating insertion groove. The outer contour shape of the cross-section of the insertion groove is pentagonal. The connecting member includes a first connecting member and a second connecting member arranged in a straight line in sequence, and the first connecting member and the second connecting member are integrally connected. The second connecting member includes a first plate, second plates fixedly connected to both sides of the first plate one by one, and third plates fixedly connected to the sides of the second plates away from the first plate one by one. The first plate, the two second plates, and the two third plates together enclose a hollow insertion portion. The first connecting member is fixedly connected to one end of the connecting rod. The insertion portion is inserted into the insertion groove, and the outer peripheral surface of the insertion portion is closely attached to the inner side surface of the insertion groove. The outer contour diameters of the cross-sections of the first side plate, the second side plate, the third side plate, and the fourth side plate gradually decrease from the end towards the connecting rod to the other end.

[0008] As an improvement of the present utility model, the first connecting member includes a connecting plate and limiting plates fixedly connected to both sides of the bottom plate one by one. The connecting plate and the two limiting plates together enclose a positioning groove. One end of the connecting rod is inserted and fixedly connected in the positioning groove.

[0009] As an improvement of the present utility model, the connecting rod is a square rod.

[0010] As an improvement of the present utility model, the outer contour shape of the cross-section of the foot is a right-angled sector.

[0011] Another object of the present application is to provide a bed frame including the above-mentioned bed frame connection structure.

[0012] Adopting the above technical solution, the present utility model has the following beneficial effects:

[0013] The utility model forms a plug-in slot in the shape of a wedge by the cooperation of a first side plate, a second side plate, a third side plate and a fourth side plate, the outer contour diameters of the cross sections of which gradually decrease from one end facing the connecting rod to the other end. The supporting feet and the connecting rod are fixed together through the cooperation of the plug-in part and the plug-in slot in the shape of a wedge. When subjected to external pressures in all directions, the plug-in part can fit more tightly as it moves downward, thereby reducing the gap and preventing shaking. The structure is simple and has relatively good stability. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following further describes the utility model in conjunction with the drawings and specific embodiments.

[0026] Embodiment 1

[0027] As Figures 1 - 2As shown in the figure, this embodiment provides a bed frame connection structure, which includes a support leg 10 and a connecting rod 20. The outer contour shape of the cross-section of the support leg 10 is a right-angled sector. The connecting rod 20 is a conventional square rod. One end of the connecting rod 20 is fixedly connected with a connecting piece, and the specific fixed connection method between the two can be a conventional method, such as welding or bonding, etc. In this embodiment, the fixed connection method is described by taking welding as an example. A clamping piece 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 cooperation of the connecting piece and the clamping piece, without the need to be connected by any bolts. Its structure is simple and convenient for assembly and disassembly.

[0028] The clamping piece 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 and the fourth side plate 24 are arranged oppositely, and both the first side plate 21 and the fourth side plate 24 are fixedly connected or integrally connected to one side wall of the support leg 10. The second side plate 22 is fixedly connected or integrally connected to the side of the first side plate 21 away from the support leg 10. The third side plate 23 is fixedly connected or integrally connected to the side of the fourth side plate 24 away from the support leg 10. The side of the second side plate 22 away from the first side plate 21 and the side of the third side plate 23 away from the fourth side plate 24 are fixedly connected or integrally connected. An acute angle is formed between the second side plate 22 and the third side plate 23. 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 20 together enclose a vertically penetrating insertion slot 25. The outer contour shape of the cross-section of the insertion slot 25 is a pentagon. The connecting piece includes a first connecting piece and a second connecting piece arranged in a straight line in sequence, and the first connecting piece and the second connecting piece are integrally connected. The second connecting piece includes a first plate, second plates respectively fixedly connected to both sides of the first plate one by one, and third plates respectively fixedly connected to the sides of the second plates away from the corresponding first plate one by one. The first plate, the two second plates and the two third plates together enclose a hollow insertion part 28. The first connecting piece is fixedly connected to one end of the connecting rod 20. The insertion part 28 is inserted into the insertion slot 25, and the outer peripheral surface of the insertion part 28 and the inner side surface of the insertion slot 25 are closely attached. The outer contour diameters of the first side plate 21, the second side plate 22, the third side plate 23 and the fourth side plate 24 all gradually decrease from the end towards the connecting rod 20 to the other end, ensuring that when the bed frame connection structure is subjected to external pressures in all directions, the lower it is, the tighter the fit, the firmer the insertion, so as to ensure that the gap between the support leg 10 and the connecting rod 20 is smaller and further improve the stability of the connection.

[0029] The first connecting piece includes a connecting plate 27 and limiting plates 26 respectively fixedly connected to both sides of the connecting plate 27 one by one. The connecting plate 27 and the two limiting plates 26 together enclose a positioning groove. One end of the connecting rod 20 is inserted and fixedly connected in the positioning groove, which ensures the stability of the connecting rod 20 and the first connecting piece in this way.

[0030] In the present utility model, a plug-in groove 25 in the shape of a wedge is formed by the cooperation of a first side plate 21, a second side plate 22, a third side plate 23, and a fourth side plate 24, whose cross-sectional outer contour diameters gradually decrease from one end facing the connecting rod to the other end. The support feet 10 and the connecting rod 20 are fixed together through the cooperation of the plug-in portion 28 and the plug-in groove 25 in the shape of a wedge. When subjected to external pressures from all directions, the lower the plug-in portion goes, the tighter it fits, and thus the smaller the gap, without wobbling. The structure is simple and has relatively good stability.
