Detailed description of the invention
Below in conjunction with accompanying drawing of the present utility model, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection.
As depicted in figs. 1 and 2, the backrest tilt adjuster for sofa of the present embodiment, including tooth clamp 1, panel 2 and cover 3.With reference to Fig. 5 and Fig. 6, one end processing of tooth clamp 1 has tooth clamp through hole 11 and five double wedges 12.One end processing of panel 2 has faceplate through holes.With reference to Fig. 7 and Fig. 8, one end processing of cover 3 has cover through hole 31, and other end processing has a cover chimb 33 and front cover installation hole 32.Center rivet 7 sequentially passes through cover through hole 31, tooth clamp through hole 11 and faceplate through holes, thus tooth clamp 1, panel 2 and cover 3 being linked together, wherein panel 2 and cover 3 lay respectively at the both sides of tooth clamp 1, panel 2 and cover 3 and form a space.
On panel 2, the processing of space place has panel mounting hole, and this panel mounting hole is mutually corresponding with front cover installation hole, and quilting rivet 8 is set in panel mounting hole and front cover installation hole.With reference to Figure 11 and 12, one end processing of tooth fixture block 5 has tooth fixture block through hole 51, the processing of other end place has teeth groove 52, tooth fixture block through hole 51 is set on quilting rivet 8, the internal diameter of tooth fixture block through hole 51 is more than the diameter of quilting rivet 8, therefore tooth fixture block 5 is rotatably installed on quilting rivet 8, in the space that panel 2 and cover 3 are formed.With reference to Figure 13, one end processing of spring 6 has draw-in groove 62, and this draw-in groove 62 fastens with cover chimb 33, and the other end of spring 6 and tooth fixture block 5 fit near teeth groove 52 place.Spring 6 applies a twisting resistance to tooth fixture block 5, makes the teeth groove 52 of tooth fixture block 5 be meshed with the double wedge of tooth clamp 1.
With reference to Fig. 9 and Figure 10, one end processing of reset card 4 has reset card through hole 41, and other end processing has reset card chimb 43 and salient point 42.Reset card through hole 41 is set in center rivet 7, so that reset card 4 is set in center rivet 7, wherein reset card 4 is located between tooth clamp 1 and cover 3, and the one side of salient point 42 and tooth clamp 1 fits.
As optimal technical scheme, with reference to Fig. 5 and Fig. 6, on tooth clamp 1, the one side processing near reset card 4 has two positive stop lug boss 13 for limiting reset card 4 position, and reset card 4 is restricted between two positive stop lug boss 13 to locate.
Below the operation principle of backrest tilt adjuster for sofa of the present utility model is described in further detail.
Backrest tilt adjuster for sofa is installed on sofa, and wherein panel 2 is connected to the headrest of sofa, and tooth clamp 1 is connected to the backrest of sofa.During use under the effect of the twisting resistance of spring 6, the teeth groove 52 of tooth fixture block 5 is meshed with the double wedge of tooth clamp 1, and headrest is positioned and fixes.Resting the head on by hand propelled when regulating headrest, motive force overcomes the twisting resistance of spring 6 to make panel 2 rotate so that the teeth groove 52 of tooth fixture block 5 departs from the double wedge 12 of tooth clamp 1, and then makes headrest rotate the angle regulating headrest.When panel 2 is positioned at level, now panel 2 is in the first extreme position as it is shown on figure 3, then panel 2 rotates clockwise, and rotational angle, more than 90 °, turns to the second extreme position, and namely return file location is as shown in Figure 4.
Backrest tilt adjuster for sofa described in the utility model, its overall structure is simple, Assembly part is less, easy to assembly, save material, each part passes through rivet interlacement, the mechanical strength of product and physical property are also strong, applying the sofa of this backrest tilt adjuster for sofa, the adjusting angle of its headrest is more than 90 °, and the range of accommodation therefore rested the head on is big.
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all within spirit of the present utility model and principle, any amendment of making, equivalent replacement, improvement etc., should be included within protection domain of the present utility model.
