Abstract

The invention discloses a silent hinge which comprises a first arm and a second arm hinged to the first arm. An elastic sheet is arranged at one end of the first arm. A round closed hole is formed in the elastic sheet and extends outwards to form an opening. A rotary shaft is fixed to the second arm. The rotary shaft is inserted into the round closed hole in a matched manner. When the rotary shaft rotates in the round closed hole in one direction relative to the first arm, the opening of the round closed hole is opened. When the rotary shaft rotates in the round closed hole in the other direction relative to the first arm, the opening of the round closed hole is made to be closed to lock the rotary shaft. The silent hinge has the beneficial effects that the silent hinge can be adjusted by any angle, no noise is generated in the rotating process, and the requirement for the strength of a material is low.

Description

Silent

Technical field

The present invention relates to hinge, especially relate to a kind of can adjust arbitrarily angled, noiselessness, the strength of materials require low silent when rotating.

Background technology

Hinge is to connect the instrument that two parts make it rotate at a certain angle, is used in various family property, household appliances. Such as, what be equipped with in sofa is connected on backrest by headrest portion and makes it can rotate the hinge of multiple angle. But, first the hinge of this employing conventional art has the problem that, in traditional hinge, by the swing engaging two parts of restriction of tine and gear. Owing to the active force between two parts is very big, this just requires that the tooth of tine and gear is relatively big, and the tooth tooth pitch of gear is very big. Therefore, and the multiple of the angle tooth pitch of its adjustment, this hinge can not carry out the adjustment of trickle angle; The tooth of tine and gear is main stressed member simultaneously, when dynamics is excessive, it is possible to the tooth fracture of tine fracture or gear, and product can be made to produce irreversible damage, and this just requires that tine and gear to have significantly high intensity; Tine stirring on gear, also can produce the noise making people fidgety.

Detailed description of the invention

Below in conjunction with embodiment and compare accompanying drawing the present invention is described in further detail.

A kind of silent of the present embodiment, refer to accompanying drawing 1 to Fig. 6, including the first arm 3 and the second arm 6 being hinged, one end of described first arm 3 is provided with shell fragment 2, described shell fragment 2 is provided with a circular obvolvent hole 21, described circular obvolvent hole 21 extends outward an opening 22, described second arm 6 is fixed with a rotating shaft 9, described rotating shaft 9 coupling inserts circular obvolvent hole 21, described rotating shaft 9 makes the opening 22 in circular obvolvent hole 21 open when the first arm 3 rotates to a direction in circular obvolvent hole 21, described rotating shaft 9 makes the opening 22 in circular obvolvent hole close locking rotating shaft 9 when the first arm 3 rotates to other direction in circular obvolvent hole 21.

Use and during this silent, first component is arranged on the first arm 3, second component is arranged on the second arm 6, the first arm 3 is made to rotate relative to the second arm 6 to regulating direction (direction of rotation is that the opening 22 making circular obvolvent hole 21 opens) rotation first component, when the direction rotating first component is to make direction that the opening 22 in circular obvolvent hole 21 opens, now relative second arm 6 in obvolvent hole 21 is free to rotate around rotating shaft 9, thus the angle regulated between first component and second component, when forwarding required angle to, the opening 22 that can make circular obvolvent hole owing to reversely rotating the first arm 3 closes locking rotating shaft 9, it is thus possible to ensure that angle when using remains unchanged. owing to this hinge adopts the combination of the shell fragment 2 with opening 22 and rotating shaft 9 to make adjustment direction can carry out electrodeless rotation, other direction locking rotating shaft 9, so that product in use have can adjust arbitrarily angled, rotate time noiseless advantage, simultaneously because adjustment structure is the contact in face, therefore the strength of materials is required low, without producing irreversible damage during use.

The silent of the present embodiment, refer to accompanying drawing 1 to Fig. 6, the basis of previous technique scheme specifically can also is that, shell fragment 2 offers opening 22 place and is provided with a bar hole, it is a bar-shaped trough 23 in the present embodiment, described first arm 3 is provided with the arc notch 31 being projected in bar-shaped trough 23 one end, slide in bar-shaped trough 23 and be provided with clutch shaft 4, distance between bar-shaped trough 23 and arc notch 31 is less than the diameter of clutch shaft 4, described clutch shaft 4 makes opening 22 elasticity in circular obvolvent hole 21 open when snapping between bar-shaped trough 23 with arc notch 31 thus relative first arm 3 of rotating shaft 9 is freely rotatable in circular obvolvent hole 21. when product utilize when being adjusted to the limit position rotating shaft 9 enlarged rounded obvolvent hole 21 (referring to figs. 2 and 5), so that the first arm 3 with regulate when direction reversely rotates will not locking, and initial position (with reference to Fig. 1 and Fig. 4) can be rotated back into and readjust.

The silent of the present embodiment, refer to accompanying drawing 1 to Fig. 6, the basis of previous technique scheme specifically can also is that, second arm 6 is provided with two protruding, in the present embodiment, two projections are extended to form by the side of the clutch-plate 1 being fixed in rotating shaft 9, relative second arm 6 of described first arm 3 turn to one spacing time, referring to figs. 2 and 5, wherein clutch shaft 4 is dialled between bar-shaped trough 23 and arc notch 31 by the first projection 11, thus enlarged rounded obvolvent hole 21, make the first arm 3 with regulate will not locking when direction reversely rotates, and initial position can be rotated back into and readjust, when returning to initial position, with reference to Fig. 1 and Fig. 4, relative second arm 6 of first arm 3 turns to that another is spacing, now second protruding 12 just by clutch shaft 4 from the inner dialing out to bar-shaped trough 23 between bar-shaped trough 23 and arc notch 31, thus product can carry out normal regulating.

The silent of the present embodiment, refer to accompanying drawing 4 to Fig. 6, the basis of previous technique scheme specifically can also is that, second arm 6 is provided with a chute 61, described chute 61 is slidably equipped with a fixture 5, first arm 3 is hinged with the first chain sheet 73, the other end of described first chain sheet 73 is hinged with the intermediate ends of the second chain sheet 72, one end of described second chain sheet 72 is hinged with one end of the 3rd chain sheet 71, the other end of described second chain sheet 72 is hinged on the second arm 6, on the hinged fixture 5 of the other end of described 3rd chain sheet 71.So, when the first arm 3 rotates relative to the second arm 6, the second arm 6 opposed fixed member 5 is made to slide up and down in chute 61 by chain sheet transmission, the first component that band is automatically connected on the first arm 3 moves up and down, this structure makes two component angles raise when becoming big, thus avoiding two parts to compress deformation, and reduce when two component angles diminish, thus avoiding there is gap between two parts.

The silent of the present embodiment, refer to accompanying drawing 4 to Fig. 6, concrete it is also possible that the first arm 3 passes through the hinged first chain sheet 73 of adjutage of a spot film 8 on the basis of previous technique scheme.
