The utility model has the advantages of refinement and flexibility, and the utility model can adjust angles and be used for sofas, anti-theft steel doors, etc.

Description

Multipurpose ratchet-type hinge

The utility model relates to a kind of adjustable angle on sofa, antitheft steel casement door, the automotive seat etc. and the multipurpose ratchet-type hinge that can locate of can be used for.

Gyrator benzene on the sofa of the convertible angle of backrest of Chu Shouing is heavy in the market, and the cost height is pressed against the people after keeping flat, and rapid wear is hurted sb.'s feelings, and is dangerous.This gyrator can only cooperate with wooden, and can not cooperate with steelframe.

In view of above reason, the purpose of this utility model is in order to provide a kind of cost low, and is small and exquisite, flexibly, safety cooperates with steelframe and to save timber, adjustable angle and can locate, not only can be used on the sofa but also can be used for multipurpose ratchet-type hinge on the security door etc.

The utility model hinge comprises the outer lock body that contains groove, pass outer lock body groove and be fixed on back shaft on the outer lock body, the end that interior lock body contains hollow ratchet tooth plate stretches in the outer lock body groove and is hinged on the back shaft, the return tongue that contains bump portion and limiting section is arranged in the groove of hollow ratchet tooth plate and is hinged on the back shaft, have on the interior lock body respectively with the return tongue on bump portion and the limiting section portion that hits and the limit shaft that cooperate, place an end of the ratchet that the ratchet with on the hollow ratchet tooth plate of outer lock body cooperates to be hinged on the pawl axis on the outer lock body, the two ends of spring are connected on pawl axis and the ratchet (referring to Fig. 1, Fig. 2).

Above-mentioned gain in strength all-in-one-piece with it being arranged on the hollow ratchet tooth plate of interior lock body and the reinforcement ratchet tooth plate (referring to Fig. 6, Fig. 7) of the ratchet identical with ratchet on the hollow ratchet tooth plate being arranged on it, long service life, manufacture craft is simple.

(16) end in (15) end in the above-mentioned outer lock body, the interior lock body is respectively tubular body (referring to Fig. 1), can plug together welding with sofa steelframe or automotive seat steelframe etc., and assembling easily.

Referring to Fig. 1～Fig. 5, when using the utility model, rotate outer lock body, because the effect of hollow ratchet tooth plate, ratchet and return tongue, outer lock body and interior lock body can be fixed on the required angle, be rotated further, bump against until bump portion on the return tongue and the portion of hitting on the interior lock body, the return tongue makes ratchet break away from ratchet ratchet jack-up, lock body outside counter-rotation, limit shaft on limiting section on the return tongue and interior lock body is collided, and the return tongue clockwise rotates, outer lock body still to counter-rotation until 180 ° of positions that become with interior lock body as shown in Figure 1.

The utility model cost is low, small and exquisite, flexible, safety, and adjustable angle and locating cooperates with steelframe, saves timber, and manufacture craft is simple, and purposes is wide, not only can be used on the sofa, on the automotive seat but also can be used on the antitheft steel casement door etc.

Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing:

Referring to Fig. 1, Fig. 2, back shaft 1, pawl axis 2 pass the groove 4 of outer lock body 3 respectively and are riveted on the outer lock body 3.An end that contains hollow ratchet tooth plate 6 of interior lock body 5 stretches in the outer lock body groove and is hinged on the back shaft.Be arranged in the groove of hollow ratchet tooth plate and be hinged on the return tongue 7 on the back shaft bump portion 8 and limiting section 9 are arranged.Have on the interior lock body respectively with the return tongue on bump portion and the bump portion 10 that matches of limiting section, be riveted in limit shaft 11 on the lock body.Ratchet 12 1 ends are hinged on the pawl axis.The two ends of spring 13 are connected on pawl axis and the ratchet.

Fig. 3 for outer lock body when interior lock body rotates on the return tongue bump portion be about to interior lock body on the portion's of hitting state diagram when colliding.

State diagram when Fig. 4 collides afterwards outer lock body backward rotation for bump portion on the return tongue and the portion of hitting on the interior lock body.

State diagram when Fig. 5 collides for the limiting section of return tongue and the limit shaft on the interior lock body.

Referring to Fig. 6, Fig. 7, can and the reinforcement ratchet tooth plate 14 of the ratchet identical with ratchet on the hollow ratchet tooth plate be arranged on it at fixing all-in-one-piece with it on the hollow ratchet tooth plate.

During installation, can become the automotive seat steelframe to plug together welding with the sofa steelframe respectively the tubular tip 16 of the outer lock body tubular tip 15 of the utility model, interior lock body.
