Problems solved by technology

The current seat frame or bed frame mostly adopts hollow tube structure in order to reduce weight and save cost, and the above-mentioned positioning buckle is only fixed on the surface of one side of the hollow tube. When in use, the force on the hollow tube is uneven, and the hollow tube is positioned The deformation under the tension of the buckle includes not only bending deformation, but also torsional deformation. After long-term use, the hollow tube is easily damaged, and increasing the strength of the hollow tube will increase the cost.
On the other hand, the location where the positioning buckle receives force is the side wall of the buckle box and the middle of the buckle box, so that the positioning buckle is unbalanced in force and will be bent and deformed, which will cause the positioning buckle to be easily damaged and the service life is not long

Embodiment 1

[0028] A built-in positioning buckle, such as Figure 1-Figure 7 As shown, it includes a connecting body 1 for connecting the seat frame, one end of the connecting body 1 is provided with a cap body 2 for positioning, and the middle part of the cap body 2 is provided with a threading hole 3 for passing a rope , the connecting body 1 is cylindrical, the hollow part of the connecting body 1 is an accommodating space 4 communicating with the threading hole, and the side of the connecting body 1 is provided with a locking part 5 .

[0029] During use, two embedded positioning buckles are respectively connected to the two ends of the rope 7, and then respectively connected to the seat, the seat is provided with a hole corresponding to the connecting body 1, and the rope 7 is an elastic rope. One end of the rope 7 is passed through the threading hole 3 of the cap body 2 and enters the accommodating space 4 of the connecting body 1 . In order to fix the end of the rope 7 in the acco...

Embodiment 2

[0036] Such as Figure 8 As shown, the difference between this embodiment and Embodiment 1 is that the threading hole 3 is two connected waist round holes or rectangular holes, and the two waist round holes or rectangular holes are connected into a "T" shape. When one rope 7 is not enough for stable fixation, a main rope 7 and an auxiliary rope 7 are used for fixing, that is, a wider rope 7 and a narrower rope 7, and the main rope 7 Pass two waist round holes or rectangular holes to connect " T " shape hole with auxiliary rope 7 .

[0037] Other technical features of this embodiment are the same as those of Embodiment 1, and will not be repeated here.

Abstract

The invention relates to the technical field of furniture, in particular to an embedded positioning buckle for fixing a rope on a backrest or a seat cushion of a seat. The embedded positioning buckle comprises a connecting body for connecting a seat bracket. A cap body for limiting is arranged at one end of the connecting body. Rope penetration holes are reserved in the middle part of the cap body, and the rope penetrates through the rope penetration holes. The connecting body is barrel-shaped. The hollow part of the connecting body is an accommodation space communicated with the rope penetration holes. A clamping part is arranged on the lateral surface of the connecting body. When the embedded positioning buckle is used, the seat bracket is provided with a hole, the connecting body is clamped with the seat bracket through the clamping part, the connecting body is uniformly stressed and reliably connected, and is difficult to damage, so that the service life is prolonged; and moreover, the stress distribution of the seat is improved, and requirements on a material for the seat are lowered.

Description

technical field [0001] The invention relates to the technical field of furniture, in particular to an embedded positioning buckle for fixing a rope to a seat back or a seat cushion. Background technique [0002] With the development of society, people pay more and more attention to the comfort of life, especially the seat; the backrest and seat cushion of the current seat are generally filled with sponge, etc., and then wrapped with leather or cloth; such seats are used It has a certain sense of comfort when using sponge as a filler, so the backrest or seat cushion is not breathable, and it is unfavorable to the body when used for a long time, and it is easy to breed bacteria, so it cannot be disassembled and cleaned. [0003] In order to allow the backrest or seat cushion to be breathable and have a certain sense of comfort, there are seats on the market that use multiple stretched ropes as the backrest or seat cushion, and the two ends of the rope are provided with positi...
