Abstract
The present invention relates to a structure of a lamp expanding upright column. The lamp expanding upright column is a group of multistage upright column bodies formed by the mutual sheathing of inner upright column bodies and outer upright column bodies, wherein each inner upright column body and each outer upright column respectively have a hollow equilateral triangle cross section, and each inner upright column body and each outer upright column are mutually and glidingly matched. Each inner upright column body freely expands and slides in the inner cavity of each outer upright column body. The hollow equilateral triangle cross section is provided with three angles in a circular arc shape and three surfaces in the circular arc shape, and the angles and the surfaces are in smooth and transitional connection. The other proposal is that the hollow equilateral triangle cross section is provided with three angles in a circular arc shape and three flat surfaces, and the angles and the flat surfaces are in smooth connection. One edge of each polygonal outer upright column body is provided with an upright column expanding and positioning mechanism with a lock pin, and another edge of the outer upright column body is provided with a lock pin hole. One edge of each inner upright column body is provided with a plurality of lock pin holes of which the positions are corresponding to the upright column expanding and positioning mechanism. The present invention has the advantages of novel structure, beautiful appearance, good rigidity of the upright column bodies, and high upright column expanding and positioning stability.
Description
Technical field
The present invention relates to a kind of light fixture equipment field, particularly relate to a kind of be applied to support lighting, have structure of lamp expanding upright column triangle circular arc, scalable adjusting.It equally also be suitable for the various ligthing paraphernalias of indoor or outdoors, camera, video camera, drawing board and other need connected, require the supporting use in the device of telescopic adjustment arbitrarily of column height.
Background technology
At present, the most section structures that adopt cylindrical tube of the scalable column of various light fixtures, also have and adopt rectangular-shaped section structure, its number of patent application that the latter such as the applicant have obtained the authorization is 03142083.4 patent of invention " Fold-style lighting collection ", it comprises a supporting seat 3, one height-adjustable telescopic column 2 is set on the described supporting seat, and the upper end of described telescopic column 2 is provided with the illuminating lamp 1 for the illumination use of band distributing box; Described telescopic column 2 can be stretched upward by three joints or the traveller of gathering is downwards formed, and described telescopic column bottom fixedly installs a distributing box that links to each other with described illuminating lamp 1 power line, as shown in Figure 4.
Three joints of above-mentioned " Fold-style lighting collection " patent of invention can stretch upward or the telescopic column of gathering downwards has rectangular-shaped section structure, and are simple and lucid and lively.Yet its rigidity of structure is not ideal, and remains in shortcoming in some occasion is used.
Summary of the invention
Purpose of the present invention is exactly in order to overcome above-mentioned weak point of the prior art, provide a kind of good looking appearance, flexible and positioning function well, structure of lamp expanding upright column with triangle circular arc.
The objective of the invention is by providing a kind of structure of lamp expanding upright column to realize with following structure, it be one group multistage, by the column body that inner column body and outer column body are nested with mutually, described inner column body that is nested with mutually and outer column body are set to hollow equilateral triangle section; The inner column body of described equilateral triangle section and the outer column body of equilateral triangle section are set to be slidingly matched mutually.
Described inner column body, outer column body with hollow equilateral triangle section respectively is set to three circular arc angles and three arc-shaped surfaces.Described circular arc angle is connected with described arc-shaped surface is smooth.
Described inner column body, outer column body with hollow equilateral triangle section respectively is set to three circular arc angles and three flat shape faces.Described circular arc angle and described flat smooth connection of shape face.
One side of described polygon outer column body is provided with the vertical column expanding and the detent mechanism of pin with lock, one side of described outer column body is provided with lockpin hole, one side of described inner column body is provided with a plurality of lockpin holes, and described lockpin hole position is corresponding with described vertical column expanding and detent mechanism.
Compared with prior art, the invention has the advantages that: 1. novel structure, good looking appearance; 2. has the good column body rigidity and the stability of vertical column expanding and location; 3. be suitable for equally all kinds of ligthing paraphernalias, camera, video camera, drawing board and other need connected, require the supporting use in the device of telescopic adjustment arbitrarily of column height.

The specific embodiment
Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.
Fig. 1, Fig. 2 show first embodiment of a kind of structure of lamp expanding upright column of the present invention.It is one group multistage, by the column body that inner column body 31 and outer column body 32 are nested with mutually, the inner column body 31 and the outer column body 32 that are nested with mutually are set to hollow equilateral triangle section; The inner column body 31 of equilateral triangle section is set to be slidingly matched mutually with the outer column body 32 of equilateral triangle section, and telescopic slide is freely in the inner chamber of outer column body 32 to make inner column body 31.
One side of polygon outer column body 32 is provided with vertical column expanding and detent mechanism 10, one side of outer column body 32 is provided with lockpin hole, one side of inner column body 31 is provided with a plurality of lockpin holes, and outer column body lockpin hole position, inner column body lockpin hole position are corresponding with described vertical column expanding and detent mechanism 10.
A kind of structure of lamp expanding upright column of the present invention is connected on the feet 30, and its top is provided with a plate 20, in order to connect various light fixtures, ligthing paraphernalia, camera, video camera, drawing board etc., as shown in Figure 1.
Fig. 3 shows second embodiment of a kind of structure of lamp expanding upright column of the present invention.Inner column body 31, outer column body 32 with hollow equilateral triangle section respectively are set to three circular arc angles 33 and three flat shape faces 36.The transition light slip of described circular arc angle 33 and described flat shape face 36.Second embodiment is more simpler and easy than the manufacture craft of first embodiment.
