Description
Technical field:
The utility model relates to a kind of furniture component, the fixed hinge of can regulate backrest, handrail or the headrest of especially a kind of sitting posture or horizontal furniture.
Background technique:
Present hinge, wherein external gear is installed in supporting cam and one and compresses between the boss, thereby makes the whole effective coverage that works with locking jaw, and a side is subjected to supporting the restriction of cam, and opposite side is subjected to compressing the restriction of boss.In this hinge, it is outwards outstanding from opposite side from a side, supporting cam to compress boss, makes hinge relatively large in the physical dimension at movable joint position.
Summary of the invention:
It is as far as possible little that technical problem to be solved in the utility model provides a kind of physical dimension, and have very big strength and try one's best big the lock adjustment scope, thereby be adapted at the fixed hinge that uses on sitting posture and the horizontal furniture.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: this fixed hinge comprises a connecting plate and a castellated plates, connecting plate is connected with the standing part of furniture, castellated plates is connected with the variable partition of furniture, it is characterized in that also being provided with locking jaw and spring, connecting plate is provided with first pin, second pin, first pin, second pin constitutes the running shaft of castellated plates and locking jaw respectively, the two ends of the gear on the castellated plates are respectively arranged with stop supporting cam, maximum angle supporting cam, locking jaw is provided with tripping jut, Surface of action and stop tooth, locking jaw and gear coupling, spring and locking jaw flexibly connect, the rotating shaft center of castellated plates, the rotating shaft center of locking jaw is all on the longitudinal midline of connecting plate, make the stopper element structure compact especially and simple, have very big grip simultaneously.
Surface of action described in the utility model can be designed as the rotating shaft eccentric with locking jaw.
Spring described in the utility model has dual functions, and on the one hand its makes the locking jaw that is in the engaging position keep and gear engagement, and its locking jaw that will be in the release position is fixed on the other hand.
Locking jaw described in the utility model is provided with a surface of contact and a backstop groove, and spring snaps in this backstop groove and is fixed when locking jaw is in the release position, and when locking jaw was in the engaging position, spring was attached on this surface of contact.Backstop groove and surface of contact are arranged on the adjacent position, thereby can distinguish locking jaw small movements between engagement and release position.This just can further reduce the physical dimension of fixed hinge.
The utility model backstop groove has the surface that a shape and a position with the anterior effect end of spring is complementary, thereby makes that when locking jaw is in releasing orientation the effect of being attached to of this surface is held in large area, and spring fixed end is clamped to be fixed on the outer cover.Like this, although the structural type of locking jaw and spring is very simple, spring also can firmly fix locking jaw.
The utility model locking jaw is designed to waveform.She Ji advantage is like this, the asymmetric arrangement of the running shaft of locking jaw, thus can optimize the geometrical shape of swingle.
Distance between the gear of the utility model castellated plates and the maximum angle supporting cam changes, and is determining fixed hinge rotational limitation angle (maximum angle).
The utility model compared with prior art, do not have or do not need a boss that compresses that stretches out gear, the physical dimension of engagement range can be designed big especially, reduced the spacing of castellated plates and locking jaw thus, make physical dimension little, strength and lock adjustment scope are bigger, are adapted at using on sitting posture and the horizontal furniture.

Embodiment:
Referring to Fig. 1～Fig. 3, the utility model embodiment fixed hinge comprises a connecting plate 2 and a castellated plates 3, and connecting plate 2 is connected with the standing part of furniture, and castellated plates 3 is connected with the variable partition of furniture.Connecting plate 2 is provided with first pin 6 and second pin 7 (or similar two objects that play the running shaft effect), so that fix outer cover 15 on the one hand, in addition～aspect constitutes castellated plates 3 and locking jaw 4 running shaft separately respectively.Castellated plates 3 has a gear 8 at the one end, and gear 8 is aimed at running shaft first pin 6 (or claiming joint shaft) of castellated plates 3.Side design at gear 8 has stop supporting cam 16, is used to limit castellated plates 3 and moves around first pin, 6 clockwise direction connecting plates, 2 directions.If the external tooth of locking jaw 4 is attached on the stop supporting cam 16 (consulting Fig. 1), then fixed hinge is in initial position.Designed a maximum angle supporting cam 10 at gear 8 opposite sides, be used to limit the maximum angle between connecting plate 2 and the castellated plates 3, can support opening between cam 10 and the gear 8 by the maximum angle that changes castellated plates 3 apart from the rotational limitation angle that decides castellated plates 3 with connecting plate 2.Locking jaw 4 is installed in the opposite of gear 8, and it is shaped as waveform, is installed in prejudicially on second rivet 7 as running shaft.Arranged several stop tooths 9 on the locking jaw 4, its shape is waveform too, just can form a kind of automatically locking jointly with gear 8 like this, thereby produces stopping function.Also be provided with Surface of action 11, tripping jut 12 and surface of contact 14 on locking jaw 4, surface of contact 14 is provided with backstop groove 13, and the position that tripping jut 12 is not meshed separates or be spaced apart.When being in the engaging position, locking jaw 4 (consults Fig. 1, locking jaw stop tooth and stop supporting cam-engaged), three stop tooths 9 of locking jaw 4 and 8 engagements of the gear of the castellated plates 3 on opposite.In order to keep this engagement, designed a spring 5, it is fixed on locking jaw 4 engaging position or applies load to it.Spring 5 can adopt leaf spring, and the effect end of spring 5 and surface of contact 14 couplings are also pressed to surface of contact 14, and the fixed end of spring 5 is fixedly clamped in outer cover sidewall 15 corresponding opening slot 17 (joint part of stopper member) linings.The rotating shaft center of the rotating shaft center of castellated plates 3, locking jaw 4 is all on the longitudinal midline of connecting plate 2.
When fixed hinge rotates, castellated plates 3 is rotated counterclockwise around first pin 6, run into tripping jut 12 up to maximum angle supporting cam 10, and continue to press to this boss, it is released and be in release position (as shown in Figure 3, locking jaw stop tooth and stop supporting cam unclamps) that then locking jaw 4 overcomes the elastic force of spring 5.When unclamping, variation has taken place with the contact position of locking jaw 4 in spring 5.For locking jaw 4 is fixed on the release position, the effect end of spring 5 slips into backstop groove 13 and location, and this moment, the effect end large size of spring 5 was pressed close to the backstop groove 13 of locking jaw 4, as locking jaw 4 in engagement.Like this, need not to handle especially or the effect end of the ground flexural spring 5 of wasting time and energy just can firmly fix locking jaw 4.In order to mesh stop tooth 9 again, castellated plates 3 can be turned clockwise facing to connecting plate 2, when first tooth 20 of gear 8 is run into tripping jut 12, and continue to press to this boss, then locking jaw 4 overcomes the elastic force of spring 5 and stop tooth 9 and gear 8 is meshed again.Like this, first tooth 20 of gear 8 just contacts with Surface of action 11, and the two ends of Surface of action 11 are subjected to the restriction of stop tooth 9 and tripping jut 12 respectively.Surface of action 11 is designed to running shaft second rivet 7 off-centre with locking jaw 4, and the several teeth in gear 8 left sides (comprising first tooth 20) can use when the locking operation like this.
The simple deformation or the combination of every the utility model embodiment technological scheme and technical characteristics all should be thought to fall into protection domain of the present utility model.
