Abstract
The utility model relates to a telescopic adjuster of a lamp, which comprises a lamp body, a support frame and two mutually symmetrical support sheets which are provided with teeth. The ends of the support sheets with the teeth, which are provided with gear teeth, are mutually engaged and fixed on the support frame through pin shafts. A plurality of groups of long connecting sheets in the same cross and overlapped arrangement structure are connected with the pin shafts between the support sheets with the teeth and connecting sheets. Two mutually symmetrical fixing screws are respectively penetrated through the other end of each of the corresponding connecting sheets to fix the connecting sheets on the lamp body. In the way, three degrees of freedom are arranged on the space of the lamp body, in another aspect, the lamp body can be limited in an excess degree of freedom which is used for supporting the constructional components of the lamp body and the function of large telescopic regulating ranges can be achieved. After fixing screws are locked, the lamp body and the telescopic structure can form a rigid whole, thereby, the exact positioning function can be achieved.
Description
Technical field
The utility model relates to light fixture support device technical field, the extension adjustment device of refering in particular to a kind of light fixture.
Background technology
At present, domestic great majority have the light fixture of telescopic adjustment function, because its bindiny mechanism's free degree is too much, also deposits light fixture and regulate defectives such as inconvenient, that fixed-site is not unique.
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 extension adjustment device of easy to adjust, the fixed position is unique, adjustable range is big light fixture is provided.
For achieving the above object, the utility model includes lamp body and bracing frame, also include two symmetrical band tooth support chips, the end that this band tooth support chip has the gear teeth is meshing with each other and is fixed on the bracing frame by bearing pin, bearing pin is connected with the some groups of long braces that are identical juxtaposition arrangement architecture between band tooth support chip and brace, wherein, the other end of these two band tooth support chips bearing pin respectively is fixed on first group two and is and intersects the end of long brace of overlap condition, the juxtaposition part of these group two long braces connects by bearing pin, the link of two whenever adjacent group leader's braces is fixedly connected by bearing pin, the end bearing pin of last group leader's brace is fixed on an end of two symmetrical braces, and two symmetrical fixed screws are worn the other end of penetrating corresponding brace respectively brace is fixed on the lamp body.
After adopting said structure, the utility model has following advantage compared to existing technology:
1. practicality easy to adjust, adjustable extent are big.
2. accurate positioning height, structural rigidity are good.
Description of drawings
Fig. 1 is the utility model structure scheme of installation.
Fig. 2 is that the utility model structure is regulated schematic diagram.
Fig. 3 is the compression schematic diagram of the utility model structure.
Fig. 4 is the stretching, extension schematic diagram of the utility model structure.
The specific embodiment
Shown in accompanying drawing 1～4: the utility model includes lamp body 10 and bracing frame 20, also include two symmetrical band tooth support chips 30, the end that this band tooth support chip 30 has the gear teeth is meshing with each other and is fixed on the bracing frame 30 by bearing pin, bearing pin is connected with the some groups of long braces 40 that are identical juxtaposition arrangement architecture between band tooth support chip 30 and brace 50, wherein, the other end of these two band tooth support chips 30 bearing pin respectively is fixed on first group two and is and intersects the end of long brace 40 of overlap condition, the juxtaposition part of these group two long braces 40 connects by bearing pin, the link of two whenever adjacent group leader's braces 40 is fixedly connected by bearing pin, the end bearing pin of last group leader's brace 40 is fixed on an end of two symmetrical braces 50, and two symmetrical fixed screws 60 are worn the other end of penetrating corresponding brace 50 respectively brace 50 is fixed on the lamp body 10.The described some groups of long braces 40 that are identical juxtaposition arrangement architecture can be one group.Described bracing frame 20 can be movably connected on the base plate 70 by connector.
During use, bracing frame 20 is movably connected on the base plate 70 by connector, both can relatively rotate the anglec of rotation of regulating lamp body 10; In addition, when unclamping fixed screw 60, the length that one side adjustable band tooth support chip 30, long brace 40 and brace 50 stretch; Can regulate the angle between lamp body 10 and the brace 50 on the other hand, after mixing up, tighten fixed screw 60, can make fixed-site on this structure; Like this, lamp body 10 spatially has 3 frees degree, i.e. the rotation of the moving of vertical direction, rotation and horizontal direction.On the other hand, can be limited in the extra dof that supports lamp body 10 structure parts, and reach the big function of telescopic adjustment scope, after fixed screw 60 lockings, lamp body 10 forms the integral body of a rigidity with stretching structure, thereby reaches the function of accurate location.In addition, according to the adjustable range needs, the group number of long support sheet 40 can increase or reduce according to actual needs.
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.
