Abstract

The utility model relates to a hinge, which comprises a base connecting sheet, a fixing connecting sheet, a limiting claw, a limiting connecting plate, a backrest connecting dental lamina, a connecting plate, a spring and the like. The backrest connecting dental lamina, the base connecting sheet and the limiting connecting plate are connected in a splicing way; the limiting claw is connected to the limiting connecting plate; and the fixing connecting sheet is connected with the backrest connecting dental lamina by the connecting plate and fixed by the spring. The hinge can be used as a furniture fitting and can achieve the conversion of three angles between the seat pad and the backrest of a couch.

Description

A kind of hinge
Technical field
The utility model relates to the sofa adjusting device, is specifically related to a kind of be used to adjust the seat bat of steel sofa and the hinge of the chicken head shape of the different use angles of backrest.
Background technology
The seat of sofa is clapped and backrest, and different angle requirements is arranged in use, and present sofa structural design can't realize the conversion adjustment of various angles between sofa seat bat and the backrest.
Summary of the invention
The purpose of this utility model, be to provide a kind of seat of realizing sofa clap and backrest between the hinge of angle adjustment.
The technical solution of the utility model is as follows.
A kind of hinge is connected between dental lamina, spring and rivet, base brace, the spacing connecting plate by base brace, fixedly connected, position-limited claw, spacing connecting plate, backrest and to connect and compose, and position-limited claw is connected on the spacing connecting plate, is fixed by a spring.Fixedly connected is connected dental lamina by connecting plate and connects with backrest, and is fixed by another spring.
The utility model can be used as furniture part and uses, the seat that can realize sofa clap and backrest between the conversion of three kinds of angles, to satisfy user's different demands.

Fig. 5-1, Fig. 5-2, Fig. 5-the 3rd, the schematic diagram of several different angles of return state.
Among the figure: 1, spring, 2, spring, 3, the base brace, 4, fixedly connected, 5, position-limited claw, 6, spacing connecting plate, 7, connecting plate, 8, connecting plate, 9, backrest connects dental lamina, 10, rivet.
The specific embodiment
Referring to Fig. 1, hinge of the present utility model adds a plate by quadric chain and constitutes, and backrest connects dental lamina 9 and position-limited claw 5 shapes at an angle, connecting plate 7,8 and spacing connecting plate 6 shapes at an angle, to finish the conversion of different angles.It specifically comprises: base brace 3, fixedly connected 4, position-limited claw 5, spacing connecting plate 6, connecting plate 7, connecting plate 8, backrest connect parts such as dental lamina 9, rivet 10 and spring 1, spring 2; Backrest connects socket connection between dental lamina 9, base brace 3, the spacing connecting plate 6, and position-limited claw 5 is connected on the spacing connecting plate 6, and is fixing by spring 2.Be connected dental lamina 9 with backrest by connecting plate 7, connecting plate 8 for fixedly connected 4 and connect, and fixing by spring 1.
Referring to Fig. 2, for hinge is in the schematic diagram of level, because the tension effect of spring 1, position-limited claw 5 is in not spacing state, and base brace 3 is connected dental lamina 9 and is in level with backrest.
Referring to Fig. 3-1, Fig. 3-2, be the schematic diagram of leisure state, when external force was rotated backrest connection dental lamina 9 in the counterclockwise direction, the crest that backrest connects dental lamina 9 slipped at the top of position-limited claw 5, position-limited claw 5 falls in the dental lamina alveolus, forms the triangle of being made up of A, B, C point; Backrest connects dental lamina 9 and cannot clockwise rotate, thereby forms spacing angle α 1=125 °..
Because the effect of thrust F1 during sofa uses, the lower end of spacing connecting plate 6 are pressed on fixedly connected 4 the defining flange D, form seat and clap 1=6 ° of level inclination β, have determined α 1 and β 1 the leisure state under.
Referring to Fig. 4-1, Fig. 4-2, be the schematic diagram of duty, when external force is rotated further backrest connection dental lamina 9 in the counterclockwise direction, the crest of dental lamina slips at position-limited claw 5 tops, and position-limited claw falls into behind the dental lamina in the alveolus, forms by A, B, the triangle that the C point is formed.Backrest connects dental lamina 9 and cannot clockwise rotate, thereby form new spacing angle α 2=105 °, because the thrust F1 effect in the sofa, spacing connecting plate 6 lower ends are pressed on fixedly connected 4 the defining flange D, form seat and clap 2=4 ° of level inclination β, determined the α 2 and β 2 under the duty.
Referring to Fig. 5-1, Fig. 5-2, Fig. 5-3, be the schematic diagram of return state, when external force was rotated further backrest connection dental lamina 9 in the counterclockwise direction, the crest that backrest connects dental lamina 9 slipped at the top of position-limited claw 5; Do not press close to owing to have spacing alveolus, the outer surface of position-limited claw 5 to be connected the external profile surface of dental lamina 9 with backrest, backrest connects dental lamina 9 and can rotate along clockwise direction, has got back to reset condition.
