Abstract
The utility model discloses a shaft positioning structure used for illuminating lamp body connection. The shaft positioning structure comprises a rotating support and positioning shafts, wherein the rotating support is used for installing an illuminating lamp body in a connection mode, and the connection end of the rotating support is provided with sleeve holes matched with the positioning shafts. Each positioning shaft comprises a shaft core and a shaft wheel. The shaft cores and the shaft wheels are of a plastic structure in an integrated forming mode. The outer side wells of the shaft wheels and the inner side walls of the sleeve holes are provided with outer wheel teeth and inner wheel teeth respectively, wherein the outer wheel teeth and the inner wheel teeth are meshed. Slit gaps and elastic ribs are arranged between the shaft cores and the shaft cores. The shaft cores are of a non-circular-shaft structure and are installed at matched groove positions to limit rotating of the positioning shafts. Because the shaft cores can not rotate, rotating adjusting is achieved only by rotating the support to rotate relative to the positioning shafts in the process of rotating adjusting, positioning is accurate through wheel tooth meshing, and the structure is stable and practical.

To achieve these goals, the technical scheme that the utility model adopts is:
The axle location structure connecting for illuminating lamp body, comprises swinging mounting and locating shaft, and described swinging mounting is used for being connected and installed illuminating lamp body, and link is provided with the trepanning matching with described locating shaft; Described locating shaft comprises axle core and arbor wheel, the plastic material structure that described axle core and arbor wheel are formed in one; Wherein, described arbor wheel lateral wall is respectively equipped with trepanning madial wall the outer gear teeth and the interior gear teeth that are meshed, between arbor wheel and axle core, be provided with crack gap and elasticity muscle, described axle core is the non-circular shaft structure of rotating for being arranged on the groove position upper limit matching locating shaft processed, because axle core can not rotate, in rotation adjustment process, only have swinging mounting to rotate with respect to locating shaft.
As the improvement of technique scheme, the outer gear teeth on described arbor wheel divide two groups of symmetry arrangement, and the interior gear teeth on described trepanning are abound with on madial wall, like this, the outer gear teeth are not corresponding with the number of teeth of the interior gear teeth, reduce the resistance producing while rotation, make to regulate easier, leicht fallen D/A.
As the further improvement of technique scheme, the curved threaded shaft core setting of the described gap of cracking, and corresponding with the position of two groups of outer gear teeth on arbor wheel, when rotation, when the outer gear teeth and interior gear teeth generation relative displacement, can provide elastically-deformable space to arbor wheel.
As the further improvement of technique scheme, described axle core is hexagonal axis structure, is arranged in the hex slot matching and plays positioning action, and hexagonal axis structure location is more firm, and processing technology is easy to realize, and it is more convenient to assemble.
As the further improvement of technique scheme, the two ends of described axle core are provided with draw-in groove, when installation, match with the limited block arranging in axle core mounting groove position, reach the effect of further restriction, increase the stability of structure.
The beneficial effects of the utility model: a kind of axle location structure connecting for illuminating lamp body of the present utility model, in locating shaft and swinging mounting adopt, the structure that the outer gear teeth are meshed, locating shaft inserts in the trepanning of swinging mounting, because being subject to the restriction of hex slot, the two ends of locating shaft can not rotate, and leave crack gap and elasticity muscle between arbor wheel on locating shaft and axle core, make arbor wheel there is elastic deformation effect, in swinging mounting rotation process, in arbor wheel pressurized generation deformation makes, the outer gear teeth produce relative displacement, while turning to suitable angle, the gear teeth again engage and reach locating effect, realizing rotational positioning regulates, accurate positioning, simple in structure, stable practical.
