Technical Field

[0001] The utility model relates to the technical field of furniture, in particular to a furniture connecting device. Background Art

[0002] Furniture refers to a large category of utensils and facilities that are essential for humans to maintain normal life, engage in production practice, and carry out social activities. Furniture has also been continuously developed and innovated with the progress of the times. Nowadays, it has a wide variety of categories, different materials, complete varieties, and various uses. It is an important foundation for establishing a working and living space. Furniture is composed of four factors: material, structure, appearance form, and function. Among them, function is the leading factor and the driving force for the development of furniture; structure is the main body and the basis for realizing the function. These four factors are interconnected and mutually restrictive. Since furniture is designed and made to meet certain material needs and usage purposes of people, furniture also has factors in terms of material and appearance form.

[0003] The Chinese utility model patent with the publication number of CN211370914U discloses a furniture connecting device. On both sides of the outer end surface of the chuck body and the seat body, symmetrically arranged barbed buckles are formed.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0030] To facilitate the understanding of this embodiment, a furniture connection device disclosed in the embodiments of the present utility model will be introduced in detail first.

[0031] Embodiment:

[0032] As Figures 1-5 shown, a furniture connection device of the present application includes a first connecting member 100 and a second connecting member 200. A first curled edge 101 extends by bending from the first side edge to the second side edge of the first connecting member 100. A second curled edge 102 extends by bending from the second side edge to the first side edge of the first connecting member 100. The first curled edge 101 and the second curled edge 102 are arranged oppositely. The thickness of the first connecting member 100 is greater than the thicknesses of the first curled plate 101 and the second curled edge 102. The second connecting member 200 includes a U-shaped body. A first edge 201 extends in a direction away from the U-shaped body from the first free end of the U-shaped body. A second edge 202 extends in a direction away from the U-shaped body from the second free end of the U-shaped body. The first edge 201 of the second connecting member 200 is placed between the first curled edge 101 and the first connecting member 100. The second edge 202 of the second connecting member 200 is placed between the second curled edge 102 and the first connecting member 100. The first connecting member 100, the first edge 201, and the first curled edge 101 are fixedly connected by three bolt nuts 300, that is, the bolt sequentially passes through the first connecting member 100, the first edge 201, and the first curled edge 101 and then is connected to the nut, thereby fixing the above three together. The first connecting member 100, the second edge 202, and the second curled edge 102 are also fixedly connected by three bolt nuts 300, that is, the bolt sequentially passes through the first connecting member 100, the second edge 202, and the second curled edge 102 and then is connected to the nut, thereby fixing the above three together. Through the above structural design, the connection strength between the first connecting member 100 and the second connecting member 200 is very good, and the connection stability is also good, and the connection strength can remain unchanged during long-term use.

[0033] Specifically, three first mounting holes 103 are arranged along the length direction of the first connecting member 100. Three second mounting holes 203 are arranged along the length direction of the bottom of the U-shaped body of the second connecting member 200, which are respectively used for connecting furniture or furniture components.

[0034] As a preferred embodiment of this example, the bolt and nut 300 includes a bolt 301 and a nut 302 threadedly connected to the bolt 301. Two threaded holes 3013 are provided on the nut 3011 of the bolt 301, and a fastening screw 3014 is threadedly connected to each threaded hole 3013. These fastening screws 3014 are also threadedly connected to the first connecting member 100, that is, the fastening screws 3014 fix the nut 3011 and the first connecting member 100 together, further improving the connection effect between the bolt and nut 300 and the first connecting member 100 and the stability of the furniture connecting device of this application.

[0035] As a preferred embodiment of this example, a washer 3015 is provided on one side of the nut 302 relative to the free end of the screw rod 3012 of the bolt 301. A spring washer 3016 is provided between the nut 302 and the washer 3015. Through the design of the washer 3015 and the spring washer 3016, the effect of elastic earthquake resistance and loosening prevention is achieved.

[0036] As a preferred embodiment of this example, a limiting plate 104 is provided at the bottom end of the first connecting member 100. During installation, one end of the second connecting member 200 enters the first connecting member 100 from the top end of the first connecting member 100. Under the action of the limiting plate 104, the second connecting member 200 is prevented from sliding out of the first connecting member 100, and the mounting holes on the first connecting member 100 and the second connecting member 200 are made to correspond one by one, facilitating the installation of the bolt and nut.

[0037] As a preferred embodiment of this example, two grooves 104 are provided on the surface of the first connecting member 100 facing the second connecting member 200 along the width direction. Two elastic protrusions 204 are provided on the surfaces of the first edge 201 and the second edge 202 of the second connecting member facing the first connecting member. The two elastic protrusions 204 correspond to the two grooves 104 one by one. When the second connecting member 200 is inserted into the first connecting member 100, when the first connecting member 100 touches the elastic protrusion 204 of the second connecting member 200, the elastic protrusion is pressed into the second connecting member 200. When the elastic protrusion 204 passes through the groove 104 of the first connecting member 100, the elastic protrusion 204 pops out of the second connecting member 200 and is inserted into the groove 104, thereby realizing the connection between the first connecting member 100 and the second connecting member 200, and further improving the connection strength and connection stability of the furniture connection.

[0038] As a preferred embodiment of this example, an inclined surface 2041 is provided on one side of the free end of each elastic protrusion 204 facing the limiting plate, so that the elastic protrusion 204 can be accurately and quickly inserted into the groove 104.

[0039] In summary, through the above structural design, the utility model solves the deficiencies in the prior art and has the characteristics of reasonable structure, good connection strength, good connection stability, etc.
