To achieve these goals, the technical solution adopted in the present invention is:
A kind of axle location structure connected for illuminating lamp body, including swinging mounting and locating shaft, described swinging mounting is used for connecting installation illuminating lamp body, connects end and is provided with the trepanning matched with described locating shaft；Described locating shaft includes that shaft core is taken turns with axle, and described shaft core and axle take turns the plastic material structure being formed in one；Wherein, described axle wheel lateral wall is respectively equipped with the external gear teeth being meshed and the interior gear teeth with trepanning medial wall, it is provided with, between axle wheel and shaft core, crack gap and elastic rib, described shaft core is for being arranged on the not rounded axle construction that the groove position upper limit locating shaft matched rotates, owing to shaft core can not rotate, during rotating regulation, only swinging mounting rotates relative to locating shaft.
As the improvement of technique scheme, the external gear teeth on described axle wheel divides two groups of symmetry arrangement, and the interior gear teeth on described trepanning are abound with on medial wall, so, external gear teeth is the most corresponding with the number of teeth of the interior gear teeth, reduce rotate time produce resistance, make regulation be easier to, leicht fallen D/A.
As the further improvement of technique scheme, described in crack that gap is curved to be arranged around shaft core, and corresponding with the position of two groups of external gear teeth on axle wheel, during rotation, when external gear teeth produces relative displacement with the interior gear teeth, it is possible to provide elastically-deformable space to axle wheel.
As the further improvement of technique scheme, described shaft core is hexagonal axis structure, plays positioning action in being arranged on the hex slot matched, and hexagonal axis structure location is more firm, and processing technique is easily achieved, and assembles more convenient.
As the further improvement of technique scheme, the two ends of described shaft core are provided with draw-in groove, match with the limited block arranged in shaft core mounting groove position during installation, reach the effect limited further, increase the stability of structure.
Beneficial effects of the present invention: a kind of axle location structure connected for illuminating lamp body of the present invention, in locating shaft and swinging mounting use, the structure that external gear teeth is meshed, locating shaft inserts in the trepanning of swinging mounting, owing to the two ends of locating shaft are limited can not rotate by hex slot, and leave, between axle wheel and the shaft core on locating shaft, crack gap and elastic rib, axle wheel is made to have elastic deformation effect, in swinging mounting rotation process, axle wheel pressurized deforms upon so that interior, external gear teeth produces relative displacement, when turning to suitable angle, the gear teeth again engage and reach locating effect, realize rotational positioning regulation, accurate positioning, simple in construction, stable practicality.
