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 retouched
State, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on this
Embodiment in utility model, it is every other that those of ordinary skill in the art are obtained under not making creative work premise
Embodiment, broadly falls into the scope of this utility model protection.
As shown in Figure 1, Figure 2 and Figure 3, the backrest tilt adjuster for sofa of the present embodiment, including panel 2, dental lamina 1 and reset card 4.
With reference to Fig. 4 and Fig. 5, one end of dental lamina 1 is machined with dental lamina through hole 11 and five double wedges 14.With reference to Fig. 6, one end of panel 2
It is machined with faceplate through holes 21, panel 2 is also machined with a block 22.With reference to Fig. 8, one end of reset card 4 is machined with reset
Card through hole 41, on reset card 4, the end away from reset card through hole 41 is machined with a bayonet socket 42.First rivet 6 depends on
Secondary through reset card through hole 41, dental lamina through hole 11 and faceplate through holes 21, panel 2, dental lamina 1 and reset card 4 are connected
Together, wherein panel 2 and reset card 4 lay respectively at the both sides of panel 2.
With reference to Fig. 7, one end of tooth fixture block 3 is machined with the first tooth fixture block through hole 31, and the other end is machined with the second tooth fixture block through hole 32
And the teeth groove 33 matched with double wedge 14.Being provided with rotating second rivet 7 on panel 2, the first tooth fixture block through hole 31 is set with
On the second rivet 7, the first tooth fixture block through hole 31 and the second rivet 7 interference fit, so that tooth fixture block 3 is fixed on the second riveting
On nail 7.
With reference to Fig. 9, torsionspring 5 processed springs through hole the 51, first extension bar 52 and the second extension bar 53, the first extension bar
It is machined with the first snap fit 521 on 52, the second extension bar 53 is machined with the second snap fit 531.Second tooth fixture block of tooth fixture block 3 leads to
