Abstract

The utility model relates to a silk rain hinge which comprises a flat gasket, an L-shaped connecting sheet, a blocking core, spindle rivets, deflection shells, a control sheet, a position-controlling blocker and a spring, etc, wherein the flat gasket, the L-shaped connecting sheet, the blocking core, a first deflection shell and the control sheet are connected with one another and are connected and fixed by the spindle rivets; the position-controlling blocker is inserted into the blocking position of the blocking core and is fixed by the spring; the L-shaped connecting sheet and the blocking core are welded into a whole; and a second deflection shell is formed with a slide rail matched with the position-controlling blocker. The silk rain hinge is mainly adopted by steel sofas, is designed for adapting to different requirements of seat bats and handrails in use, can realize adjustment of five angles, is small in shape and high in strength, and can be dismounted.

Description

The very light rain hinge

Technical field

The utility model relates to the sofa adjusting device, is specifically related to required different angles such as a kind of steel sofa seat and backrest, head rest, handrail and the very light rain hinge adjusted.

Background technology

When cooperating between the backrest of sofa seat and sofa, head rest, the handrail, different demands are arranged in fact.But can't realize the conversion adjustment of similar various angles in the prior art.

Summary of the invention

The purpose of this utility model is to provide a kind of very light rain hinge of realizing carrying out between sofa seat and sofa backrest, head rest, the handrail angle adjustment.

The technical solution of the utility model is as follows.

A kind of very light rain hinge, it comprises plain cushion, L type brace, screens core body, mandrel rivet, the first displacement housing and the second displacement housing that is attached thereto and control strip, control bit card part and spring etc.; Wherein, after pegging graft between plain cushion, L type brace, screens core body, the first displacement housing, the control strip, fix by the cross-under of mandrel rivet; Fix in the different screens of control bit card part insertion screens core body and by spring.L type brace and screens core body are welded as a whole.The front end of control bit card part is an inclined-plane, and this inclined-plane can insert in the screens core body.Be formed with the slideway that cooperates with the control bit card part on the second displacement housing.

Very light rain hinge of the present utility model mainly is used on the steel sofa, be adapted to seat clap with handrail in use different requirements and design, can realize the adjustment of five kinds of angles.Its profile is little, and the intensity height can dismounting.

The specific embodiment

Referring to Fig. 1, the very light rain hinge comprises parts such as plain cushion 1, L type brace 2, screens core body 3, mandrel rivet 4, the first displacement housing 5 and the second displacement housing 6 that is attached thereto, control strip 7, control bit card part 8, spring 9; After pegging graft between plain cushion 1, L type brace 2, screens core body 3, the first displacement housing 5, the control strip 7, be connected and fixed by mandrel rivet 4; Control bit card part 8 inserts in the screens of screens core bodys 3, fixing by spring 9.In concrete implementing process, L type brace 2 welds mutually with screens core body 3.The front end of control bit card part 8 is an inclined-plane, among the screens that snaps in screens core body 3.Be formed with the slideway that cooperates with control bit card part 8 on the second displacement housing 6.Referring to Fig. 2, on the screens core body of casting by malleable iron 3, be provided with several different screens faces A, B, C, D.

Referring to Fig. 3, the very light rain hinge is in level.Because spring 9 effects, control bit card part 8 is inserted in the V-type groove of screens core body 3, and the first displacement housing 5 cannot rotate counterclockwise, and the second displacement housing 6 is limited in level.

Referring to Fig. 4, the very light rain hinge is in a retaining state.Because control bit card part 8 has an inclined-plane, control bit card part 8 is subjected to the pressure on inclined-plane and returns the V-type groove of screens core body 3, and rotate along clockwise direction, when forwarding second screens face V-type groove to, in control bit card part 8 insertion grooves, the first displacement housing 5 is controlled in first gear, can not rotate counterclockwise, and forms 1=60 ° of the first gear angle [alpha].Referring to Fig. 5, the very light rain hinge is in two retaining states.In like manner, formed second gear, angle [alpha] 2=80 °.

Referring to Fig. 6, because the D face stops on the screens core body 3, when the first displacement housing 5 continues to clockwise rotate when forming α=97 °, control bit card part 8 sliding being raised on the control strip 7, the top of control bit card part 8 falls in the groove on the control strip 7, arc surface on the control strip 7 has covered the V-shaped groove on the screens core body 3, and the first displacement housing 5 can rotate counterclockwise, and is the return state.When turning to the C point of screens core body, referring to Fig. 7, control strip 7 limited (spacing state) is controlled fastener 8 landings, is inserted in the V-type groove, thereby returns to the initial level state.
