Abstract

The utility model discloses a movable articulation joint that is buckled by two articulation pieces. One end of the articulation piece is a circular articulation part, while the other end is a supporting arm coupling end. The utility model is characterized in that: a tubular concave hole is arranged in the middle of a circular articulation part, while the other circular articulation part is provided with a circular convex column that is buckled with the tubular concave hole, in which a locating device is arranged; the locating device arranged at the inner wall of the tubular concave hole is provided with an annular flute, a hole is arranged at the corresponding position of the column; a spring and a locating piece are arranged in the hole, the locating piece is buckled into annular flute rightly. The movable articulation joint in the aforesaid structure has the advantages of compact and beautiful outline, flexibility and durability, which not only can be applied as accessories for desk and chair but also can be applied in other parts with a movable articulation.

Description

A kind of joint that is movably hinged

Technical field

The utility model relates to and connects the joint technical field.

Background technique

The turning joint of prior art or articulated mounting generally adopt and establish pivot in articulated elementss, the two ends of pivot link together articulated elements, as application number be 00217483, the applying date is that April 29, denomination of invention in 2000 are a kind of patent application of turning joint, it comprises U type pedestal and two active side seats, the active side seat is rotationally connected by pivot and pedestal, the outer coupler link of active side seat; Pedestal is provided with the pressure hook body, and the motion by the pressure hook body is freely amounted to side seat and pedestal, and the pressure hook piece is provided with the rectangular guide hole, and both sides are provided with the hook of amounting to side pedestal bayonet lock hook, and the spring seat of a projection is arranged at the top, and the pressure hook piece combines with pedestal by spring.Shortcomings such as other turning joint of the turning joint of said structure and prior art or articulated mounting be the same all to have outside the articulated section internal structure is exposed to, and profile is not attractive in appearance, and hinge is fragile, and the gap between the articulated elements is bigger, and working life is long.

Technology contents

The purpose of this utility model is to overcome above-mentioned deficiency and provides a kind of external form compactness attractive in appearance, the long-lived joint that is movably hinged.

In order to achieve the above object, the utility model has adopted following technological scheme: this is movably hinged the joint and is made of two articulated elementss fastening, articulated elements one end is circular articulated section, one end is the support arm connecting end, have tubular shrinkage pool in the one circular articulated section, another circular articulated section is provided with circular convex cylindrical body, cylindrical body and tubular shrinkage pool fasten and adapt, be provided with an annular groove at tubular shrinkage pool inwall, the cylindrical body corresponding position has the hole, be provided with spring and locating piece in the hole, this locating piece buckles into annular groove just.

Adopt the beneficial effects of the utility model of said structure to be:

Owing to reduced hinge in the articulation joint, change by being fastened and connected of pore and Cylindrical object, snap together between the articulated elements, and buckle in the annular groove by locating piece and to locate, engage compactness between the articulated elements, between the articulated elements gap, beautiful shape can not appear; The joint that is movably hinged is compared to prior art compared simultaneously, has improved its working life greatly, and is durable in use more flexibly.

Description of drawings

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1 is the utility model decomposition texture schematic representation;

Fig. 2 is Fig. 1 articulated section A-A sectional structure schematic representation;

Fig. 3 is Fig. 1 articulated section B-B sectional structure schematic representation.

Embodiment

As Fig. 1～shown in Figure 3, the joint that is movably hinged of the present utility model is by two articulated elementss 1,2 fasten formation, articulated elements one end is circular articulated section 1-1,2-1, one end is support arm connecting end 1-2,2-2, have tubular shrinkage pool 3 among the one circular articulated section 1-1, another circular articulated section 1-2 is provided with circular convex cylindrical body 4, cylindrical body 4 fastens with tubular shrinkage pool 3 and adapts, and is provided with positioning device between them, and its positioning device is for to be provided with an annular groove 3-1 at tubular shrinkage pool 3 inwalls, cylindrical body 4 corresponding positions have through hole 5, be provided with spring 6 in the hole 5, its two ends are provided with locating piece 7, and this locating piece 7 can be hoodle, also can be positioning rod, this locating piece 7 buckles into annular groove just.

During installation, step-by-step locating piece 7 places in the annular groove of tubular shrinkage pool 3, can make two articulated elements strong bonded together, and locating piece 7 can slide in annular groove, and the joint is rotated flexibly.
