Description

Technical Field

[0001] The present invention belongs to the field of folding furniture, and particularly relates to a folding hinge and furniture such as tables, beds, doors and windows, wardrobes, etc. to which the folding hinge is applied. Background Art

[0002] Folding furniture such as tables, beds, doors and windows, wardrobes, etc. are connected to the body through folding hinges, enabling the bodies to rotate relative to each other, thereby achieving the purpose of folding or unfolding. When more than two bodies are installed on the folding furniture, each body is sequentially connected into one body, and two connecting parts of the folding hinge are correspondingly installed between adjacent two bodies. When folding, each body is stacked in turn in the folding manner of a folding fan. After folding in this way, adjacent two bodies cannot limit each other and will unfold automatically to form a certain unfolding angle, and cannot be folded flatly, which is not conducive to the overall space placement; and there is still a large distance between the two connecting parts of the folding hinge after folding, resulting in a gap between the bodies and they cannot be completely overlapped, occupying the storage space of the body folding body in the length direction and affecting the overall effect of folding storage. Summary of the Invention

[0003] The purpose of the present invention is to provide a folding hinge, so that the folding furniture is not easily unfolded after folding and saves the storage space of the folding body in the length direction.

[0004] The folding hinge includes a first mounting seat, a connecting component and a second mounting seat. The first mounting seat is connected to the second mounting seat through the connecting component, enabling the first connecting seat and the second connecting seat to move relative to each other in a flush state and be able to rotate from the flush state to a relative state.

[0005] The connecting component includes a first connecting piece and a second connecting piece. Two ends of the first connecting piece are respectively rotatably connected to the first mounting seat and the second mounting seat, and two ends of the second connecting piece are respectively rotatably connected to the first mounting seat and the second mounting seat.

[0006] One end of the first connecting piece is slidably connected to the first mounting seat, and one end of the second connecting piece is slidably connected to the second mounting seat.

[0007] The other end of the first connecting piece is provided with a first limiting piece for sliding limit of the second connecting piece, and the other end of the second connecting piece is provided with a second limiting piece for sliding limit of the first connecting piece.

[0008] One end of the first connecting piece and one end of the second connecting piece are both provided with a first bending plate. The first bending plates are rotatably connected through a sliding rod, and the sliding rod is correspondingly slidably installed on the first mounting seat and the second mounting seat.

[0009] The first limiting member and the second limiting member are both barbs for hooking the sliding rod. The barbs are correspondingly connected to the other ends of the first connecting piece and the second connecting piece through the second bent plate. The second bent plate is rotatably connected through a pin shaft, and the pin shaft is correspondingly installed on the first mounting seat and the second mounting seat.

[0010] A gasket is provided between the first connecting piece and the second connecting piece.

[0011] The pin shaft and the barbs are both arranged below the sliding rod, and the end height of the first bent plate is greater than the end height of the second bent plate.

[0012] The first mounting seat and the second mounting seat both include a mounting plate and a receiving groove. The first connecting piece and the second connecting piece are both installed along the receiving groove. The two sides of the receiving groove are provided with mounting plates, and sliding grooves are provided along the two sides of the receiving groove. The two ends of the sliding rod are correspondingly and slidably installed in the sliding grooves.

[0013] The furniture includes the above folding hinge and further includes at least two boards. Two adjacent boards are installed through the folding hinge. The boards can be folded from the outside to the inside and nested into a folded body.

[0014] The beneficial effects of the present invention are as follows: The first connecting piece and the second connecting piece are both rotatably connected at one end and rotatably and slidably connected at the other end. By the relative or opposite sliding of the first connecting piece and the second connecting piece, the first mounting seat and the second mounting seat move towards or away from each other in a flush state. When the first mounting seat and the second mounting seat move away from each other, the distance between the first mounting seat and the second mounting seat continuously increases, so that an installation distance for placing multiple boards is formed between the first mounting seat and the second mounting seat. At the same time, when the first mounting seat and the second mounting seat rotate relatively to a relative state and fold, and the barbs hook the sliding rod to limit the first mounting seat and the second mounting seat, so that the boards correspondingly installed on the first mounting seat and the second mounting seat are folded from the outside to the inside and nested in multiple layers, thereby saving storage space in the length direction of the folded body.

Specific embodiments

[0016] The present invention will be further described in detail below with reference to the accompanying drawings.

[0017] As Figure 1 、 6 shown, the folding hinge E includes a first mounting seat 1, a connecting component and a second mounting seat 2. The first mounting seat 1 and the second mounting seat 2 have the same structure and both include a mounting plate 3 and a receiving groove 4. Both ends of the receiving groove 4 are through grooves. The top surfaces on both sides of the receiving groove 4 extend out the mounting plates 3 arranged along the length direction of the receiving groove 4. Mounting holes 17 for mounting the furniture body are provided on the mounting plates 3. The mounting holes 17 are evenly distributed on the mounting plates 3. Sliding grooves 5 arranged along the length direction of the receiving groove 4 are provided on both sides of the receiving groove 4. Both ends of the sliding grooves 5 are closed.

[0018] As Figure 1 、 2 、3, 4, and 5 shown, the connecting component is composed of a first connecting piece 6 and a second connecting piece 7. There are two groups of the first connecting piece 6 and the second connecting piece 7 respectively. Each group is completely overlapped by three connecting pieces A. Each connecting piece A has the same structure and is integrally formed. One end of the connecting piece A is provided with a first bent plate 8. The first bent plate 8 is rotatably connected through a sliding rod 9. The other end of the connecting piece A is provided with a second bent plate 11. A barb 10 is provided at the end of the second bent plate 11. The barb 10 serves as the first limiting member and the second limiting member. The second bent plate 11 is rotatably connected through a pin shaft 12.

[0019] When the first mounting seat 1 and the second mounting seat 2 move towards each other and close together in a flush state, the first connecting piece 6 is located in the receiving groove 4 of the first mounting seat 1, and the second connecting piece 7 is located in the receiving groove 4 of the second mounting seat 2. A sliding rod 9 passes through the ends of the first bent plates 8 of each connecting piece A of the two groups of the first connecting pieces 6. The two ends of the sliding rod 9 are correspondingly slidably mounted in the sliding grooves 5 of the first mounting seat 1; another sliding rod 9 passes through the ends of the first bent plates 8 of each connecting piece A of the two groups of the second connecting pieces 7. The two ends of the sliding rod 9 are correspondingly slidably mounted in the sliding grooves 5 of the second mounting seat 2. A pin shaft 12 passes through the connection between the second bent plate 11 and the barb 10 of each connecting piece A of the two groups of the first connecting pieces 6. The two ends of the pin shaft 12 are fixed on both sides of the receiving groove 4 of the first mounting seat 1; another pin shaft 12 passes through the connection between the second bent plate 11 and the barb 10 of each connecting piece A of the two groups of the second connecting pieces 7. The two ends of the pin shaft 12 are fixed on both sides of the receiving groove 4 of the second mounting seat 2.

[0020] When the first mounting seat 1 and the second mounting seat 2 move back to back in a flush state, since the two groups of first connecting pieces 6 and the two groups of second connecting pieces 7 are staggered in the width direction of the accommodating groove 4, one group of first connecting pieces 6 slides between the two groups of second connecting pieces 7, one group of second connecting pieces 7 slides between the two groups of first connecting pieces 6, the connecting pieces A on the outer sides of the other group of first connecting pieces 6 slide along the inner walls of the accommodating grooves 4 of the first mounting seat 1 and the second mounting seat 2, and the connecting pieces A on the outer sides of the other group of second connecting pieces 7 slide along the inner walls of the accommodating grooves 4 of the first mounting seat 1 and the second mounting seat 2; and since the head and tail ends of each connecting piece A of the two groups of first connecting pieces 6 are reversed with the head and tail ends of each connecting piece A of the two groups of second connecting pieces 7, by setting the bending angle B of the first bent plate 8 to be greater than the bending angle B of the second bent plate 11, the end height C of the first bent plate 8 is greater than the end height C of the second bent plate 11, so that each pin shaft 12 and each barb 10 are located below each slide rod 9, thereby avoiding interference between the connecting pieces A during the sliding process. In addition, a gasket D is welded at the root of the two outer connecting pieces A of one group of first connecting pieces 6, and a gasket D is welded at the root of an inner connecting piece A of another group of first connecting pieces 6. By providing the gasket D, the first connecting piece 6 and the second connecting piece 7 are pressed and limited in the width direction of the accommodating groove 4, thereby preventing the first connecting piece 6 and the second connecting piece 7 from swinging during the sliding process, thereby ensuring smooth sliding of the connecting piece A.

[0021] like Figure 1 , 2As shown in Figures 3, 4, 5, and 6, the furniture such as a table, a bed, etc. includes three boards. Two adjacent boards are fixedly screwed through the mounting holes 17 of the mounting plate 3 of the first mounting seat 1 and the second mounting seat 2 of the above folding hinge E. Each board is folded from the outside to the inside and nested into a folding body. Since each connecting piece A of the first connecting piece 6 and each connecting piece A of the second connecting piece 7 are rotatably connected by the second bent plate 11 at one end driving the barb 10 to rotate along the pin shaft 12, and the first bent plate 8 at the other end rotates along the sliding rod 9 and the sliding rod 9 is slidably connected along the sliding groove 5. By the first mounting seat 1 and the second mounting seat 2 moving away from each other in the flush state, the first connecting piece 6 and the second connecting piece 7 slide towards each other and fold together, so that a spacing is generated between the first mounting seat 1 and the second mounting seat 2. This spacing forms a placement space. When the first mounting seat 1 and the second mounting seat 2 move away from each other until the sliding rod 9 slides to the closed end of the sliding groove 5 and is limited, the maximum spacing is formed between the first mounting seat 1 and the second mounting seat 2. This maximum spacing forms the maximum placement space 16. At this time, the first mounting seat 1 and the second mounting seat 2 are rotated relatively from the outside to the inside to the relative state and folded, and the barb 10 hooks the sliding rod 9 to limit the first mounting seat 1 and the second mounting seat 2, so as to stack the first board 13 and the second board 14. Similarly, with the same folding direction as that of the first board 13 and the second board 14, that is, folding from the outside to the inside, the second board 14 and the third board 15 are also stacked, and the third board 15 is just placed in the maximum placement space 16, so that the first board 13, the second board 14, and the third board 15 can be closely nested into a folding body, thereby saving storage space in the length direction of the folding body. By setting the length of the connecting piece A, the size of the maximum placement space 16 is changed to meet the placement space for the thickness of multiple boards, so as to achieve the folding effect of multi-layer nested folding and expand the use range of the folding furniture.
