Abstract

The utility model relates to a universal connecting mechanism for a lamp shade, which is arranged between a connector or a rocker and the lamp shade and comprises a universal ball, a fixed plate, a steel ball, a pressing ring, an adjusting spring and the like. The drum-shaped universal ball is directionally sleeved and fixed on a projecting shaft of the connector or the rocker; a concave circular groove is formed on the spherical surface of the universal ball in the axial direction; the fixed plate and the pressing ring are provided with matched inner spherical surfaces and are matched with the universal ball through the spherical surfaces; the fixed plate is fixed at one end of the lamp shade; a limiting step is arranged on the inner spherical surface of the fixed plate; the steel ball is arranged between the concave circular groove of the universal ball and an inner concave circle of the fixed plate, and moves along the concave circular groove of the universal ball to realize the universal and flexible rotation and adjustment of the lamp shade relative to the connector or the rocker; the rotation and adjustment angle can not exceed 360 degrees due to the limitation of the limiting step; and the adjusting spring is used for tightness adjustment. The universal connecting mechanism has the advantages of simple structure and convenience in adjustment.

The universal bindiny mechanism of lampshade

Technical field

The utility model relates to a kind of bindiny mechanism of light fixture lampshade, relate in particular to a kind of can universal rotation but rotational angle does not exceed 360 ° the universal bindiny mechanism of lampshade again.

Background technology

Light fixture is of a great variety, light fixture with illumination, amplification is called lamp for magnifying glass, no matter be any light fixture, except the wall hanging lifting is fixing, also have desk-top or console mode, light fixture is dismountable fixed with the general employing of being connected of lamp socket, as want to realize multi-angle, multi-direction illumination, the knockdown more piece of general employing connects, and the structure more complicated is used also trouble.

Summary of the invention

Goal of the invention of the present utility model be to overcome the defective of prior art and provide a kind of can universal rotation but rotational angle does not exceed 360 ° the universal bindiny mechanism of lampshade.

Goal of the invention of the present utility model is achieved through the following technical solutions: the universal bindiny mechanism of a kind of lampshade, this mechanism is located between connector and the lampshade, it is characterized in that described bindiny mechanism comprises that directed suit is fixed on the multi-directional ball on the connector projecting shaft, described multi-directional ball is cydariform, and sphere upper edge axis direction is provided with recessed circular groove; Fixed head and trim ring are provided with the Internal Spherical Surface that matches with the multi-directional ball sphere, coincide on multi-directional ball with this Internal Spherical Surface, and fixed head is fixed on the lampshade again simultaneously; Also be provided with the indent circle on the described fixed head, on the inner peripheral surface of indent circle, be provided with limited step; Between the indent circle of the recessed circular groove of described multi-directional ball and fixed head, be provided with along the steel ball of universal ball impression circular groove activity; Simultaneously between multi-directional ball and lampshade, be provided with regulating spring.

Described connector is connector or rocking bar, and connector and rocking bar are equipped with the projecting shaft of disjunctor.

It is the keyway that the protruding key of disjunctor and multi-directional ball on the projecting shaft are equipped with mutually that the orientation of described multi-directional ball and connector projecting shaft connects.

Limited step on the described fixed head is provided with 1～2.

Compared with prior art, the rotary spacing of lampshade employing multi-directional ball syndeton of the present utility model and limited step makes lampshade can reach universal flexible rotation but rotational angle does not exceed 360 °, and it is simple in structure, regulates easy.

The specific embodiment

In conjunction with the accompanying drawings the utility model embodiment is specifically described again below.

Shown in Fig. 1～7, among the figure 1, connector, 11, protruding key, 12, projecting shaft, 2, multi-directional ball, 21, recessed circular groove, 22, keyway, 3, fixed head, 31, Internal Spherical Surface, 32, indent circle, 33, limited step, 4, steel ball, 5, trim ring, 6, regulating spring, 7, lampshade, 8, screw, 9, connector, 10, rocking bar.

The universal bindiny mechanism of lampshade, shown in Fig. 1～3, this bindiny mechanism is located between connector 1 and the lampshade 7, comprises by multi-directional ball 2, fixed head 3, steel ball 4, trim ring 5 and regulating spring 6 etc. constituting.

The embodiment 1 of described connector 1 is the connector 9 of Fig. 2 or the rocking bar 10 of embodiment 2 Fig. 3, and connector and rocking bar are equipped with the projecting shaft 12 of disjunctor and the protruding key 11 of disjunctor on the axle, single injection-molded.

Described multi-directional ball 2 is cydariform shown in Fig. 4～5, two ends are big or small transverse plane, utilizes keyway 22 orientations of self to be fitted on the protruding key 11 of projecting shaft 12, and gluing being fixed as one, and the sphere upper edge axis direction of multi-directional ball is provided with recessed circular groove 21.Multi-directional ball must be overlapped upper mounted plate earlier before the projecting shaft of gluing upper binding head or rocking bar.

Described fixed head 3 is shown in Fig. 6～7, be provided with the Internal Spherical Surface 31 of coincideing with multi-directional ball 2 spheres, also be provided with the indent circle 32 identical with universal ball impression circular groove 21 radius size, be provided with 1 or 2 limited steps 33 on the inner peripheral surface of indent circle, the present embodiment accompanying drawing is 2.Fixed head 3 is fastened on lampshade 7 ends with 4 screws 8, does universal rotation adjusting and is subjected to the spacing adjustable range that makes of limited step not exceed 360 ° along multi-directional ball in company with lampshade.
