Description
Technical field
The utility model relates to light fixture support device technical field, refers in particular to a kind of rotation positioning device of light fixture.
Background technology
At present, the rotational structure of domestic most of light fixtures by two parts in relative rotation frictional force locate, the shortcoming of this mode is that the size of frictional force is not easy to control, and is subjected to extraneous vibration etc. to influence just positioning easily behind the location.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point of the prior art and a kind of rotation positioning device of light fixture of easy to adjust, simple in structure, accurate positioning is provided.
For achieving the above object, the utility model includes bracing frame and flat board, also include the profile of tooth rolling disc and the waist shape screw rod that are evenly distributed with some circle-arc teeth on the circumference, offer the waist through hole that cooperates with waist shape screw rod at the bracing frame center, also offer the waist through hole that cooperates with waist shape screw rod at profile of tooth rolling disc center, on flat board, offer centre bore, waist shape screw rod is worn the waist through hole of penetrating bracing frame successively, dull and stereotyped centre bore, be connected with nut thread behind the waist through hole of profile of tooth rolling disc, one end of spring stator is fixed on the flat board, and the other end of spring stator supports and is located on the circle-arc tooth of profile of tooth rolling disc.
After adopting said structure, the utility model has following advantage compared to existing technology:
1. easy to adjust, simple in structure.
2. accurate positioning, widely applicable.
Description of drawings
Fig. 1 is the user mode schematic diagram of the utility model structure.
Fig. 2 is the decomposing schematic representation of the utility model structure.
Fig. 3 is the user mode decomposing schematic representation of the utility model structure.
The specific embodiment
Shown in accompanying drawing 1～3: the rotation positioning device of the utility model light fixture, include bracing frame 10 and dull and stereotyped 20, also include the profile of tooth rolling disc 30 and the waist shape screw rod 40 that are evenly distributed with some circle-arc teeth on the circumference, offer the waist through hole 11 that cooperates with waist shape screw rod 40 at bracing frame 10 centers, also offer the waist through hole 31 that cooperates with waist shape screw rod 40 at profile of tooth rolling disc 30 centers, on dull and stereotyped 20, offer centre bore 21, waist shape screw rod 40 is worn the waist through hole 11 of penetrating bracing frame 10 successively, dull and stereotyped 20 centre bore 21, waist through hole 31 backs of profile of tooth rolling disc 30 are threaded with nut 50, one end of spring stator 60 is fixed on dull and stereotyped 20, and the other end of spring stator 60 supports and is located on the circle-arc tooth of profile of tooth rolling disc 30.Between described bracing frame 10 and dull and stereotyped 20, also accompany pad 70, and pad 70 is set on waist shape screw rod 40 shafts.One end of described spring stator 60 is fixed on dull and stereotyped 20 by screw 80.Be connected with lamp expanding adjusting device 90 10 times at described bracing frame, include light fixture 91, two symmetrical band tooth support chips 92, the end that this band tooth support chip 92 has the gear teeth is meshing with each other and is fixed on the bracing frame 10 by bearing pin, bearing pin is connected with the some groups of long braces 93 that are identical juxtaposition arrangement architecture between band tooth support chip 92 and brace 94, wherein, the other end of these two band tooth support chips 92 bearing pin respectively is fixed on first group two and is and intersects the end of long brace 93 of overlap condition, the juxtaposition part of these group two long braces 93 connects by bearing pin, the link of two whenever adjacent group leader's braces 93 is fixedly connected by bearing pin, the end bearing pin of last group leader's brace 93 is fixed on an end of two symmetrical braces 94, and two symmetrical fixed screws 95 are worn the other end of penetrating corresponding brace 94 respectively brace 94 is fixed on the light fixture 91.
During use, during rotary support frame 10, rotary support frame 10 drives profile of tooth rolling disc 30 by waist shape screw rod 40 and rotates synchronously, when profile of tooth rolling disc 30 rotates, be subjected to the effect of spring stator 60, tooth of profile of tooth rolling disc 302 revolutions overcomes the elastic force of spring stator 60 and rotates with regard to need, thereby effectively located, so just can make whole light fixture rotate an angle among a small circle and just have positioning function.When practical application, the circular arc number of teeth of profile of tooth rolling disc 30 can be determined according to the actual needs.Under described bracing frame, can be connected with the lamp expanding adjusting device, thereby make light fixture have 3 frees degree, can free adjustment.
The above only is preferred embodiment of the present utility model, and all equalizations of being done according to the utility model claim scope change and modify, and all should belong to the covering scope of the utility model claim.
