Detailed description of the invention
In order to there be understanding clearly to technical characteristic of the present invention, object and effect, now contrast accompanying drawing and describe the specific embodiment of the present invention in detail.
As shown in Figure 1, be a preferred embodiment of expansion bracket of the present invention, this expansion bracket can be used for the height regulating the equipment such as light fixture.This expansion bracket comprises: scalable support body 1, this scalable support body 1 is formed by connecting by multiple telescopic unit 10, in the embodiment shown in fig. 1, scalable support body 1 is made up of 3 telescopic units 10, and each telescopic unit comprises two the first cross-shaped braces 100.As shown in Figure 2, the first brace 100 can adopt stamping parts, and the two ends of the first brace 100 have the middle part being flexibly connected hole 101, first brace 100 respectively and have locking hole 102.First brace 100 of adjacent two telescopic units 10 is rotationally connected by the first rotational pin 111, two the first braces 100 are worn together through the flexible connection hole 101 of two connected the first braces 100 by the first rotational pin 111, make the two relatively rotate, the first rotational pin 111 can adopt bolt or rivet etc.
In expansion bracket of the present invention, one of them telescopic unit 10 of multiple telescopic units 10 of scalable support body 1 is provided with clamping screw 120, this clamping screw 120 is through the locking hole 102 of two the first braces 100 of this telescopic unit 10, and the middle part of two the first braces 100 of remaining each telescopic unit 10 of expansion bracket is not connected.Although in shape, scalable support body 1 is a bit similar with existing scissor expansion bracket, and the structure of the two has the difference of essence.The middle part of two braces that the often group of scissor expansion bracket intersects is all be rotationally connected by bearing pin, nor with clamping screw, generally relies on cylinder or oil cylinder pushing fulcrum, drives the distortion of expansion bracket to stretch.
Expansion bracket of the present invention also comprises: two the second braces 200, referring to Fig. 3, the two ends of the second brace 200 are provided with the second connecting hole 201, the first end of two the second braces 200 is connected by the first fastening bolt 410, and the second end of two the second braces 200 is rotationally connected with two the first braces 100 of the telescopic unit 10 of the first end of scalable support body 1 respectively by the second rotational pin 112.
Expansion bracket of the present invention also comprises: two the 3rd braces 300, referring to Fig. 4, the two ends of the 3rd brace 300 are provided with the 3rd connecting hole 301, the first end of two the 3rd braces 300 is connected by the second fastening bolt 420, and the second end of two the 3rd braces 300 is rotationally connected with two the first braces 100 of the telescopic unit 10 of the second end of scalable support body 1 respectively by the 3rd rotational pin 113.
When expansion bracket of the present invention uses, second end of expansion bracket is fixed on base, particular by the second fastening bolt 420, the 3rd brace 300 and base are fixed together, the first end of expansion bracket then fixes with needing the equipment adjusting height, is fixed together by the second brace 200 particular by the first fastening bolt 410 with this equipment.When two the second braces 200 are locked together by the first fastening bolt 410, and two the first braces 100 that clamping screw 120 connects by clamping screw 120 are when being locked together, telescopic unit 10 between first fastening bolt 410 and clamping screw 120 intersects locked, during adjustment height, unclamp clamping screw 120, stretch or shrink the length of scalable adjustment rack 1, then clamping screw 120 is locked, also can by the position of adjustment clamping screw 120, such as insert in the locking hole 102 of two the first braces 100 of another telescopic unit 10, the quantity changing the locked telescopic unit 10 of intersection adjusts the length of expansion bracket.Clamping screw 120 can be positioned on the telescopic unit 10 in the middle part of scalable support body 1 or be positioned on the telescopic unit 10 on scalable support body 1 top, or is positioned on the telescopic unit 10 of scalable support body 1 bottom.
Referring to Fig. 5 and Fig. 6, be the schematic diagram with the preferred embodiment of the light fixture of above-mentioned expansion bracket of the present invention, the light fixture of this embodiment comprises lamp body 2 and base 3, and lamp body 2 expansion bracket above-mentioned with base 3 is connected.
Concrete, in the present embodiment, lamp body 2 is connected with base 3 by two expansion brackets.Lamp body 2 is provided with two connecting portions 21, correspondingly on lamp socket 3 is provided with two connection brackets 5, connected by expansion bracket between connecting portion 21 and connection bracket 5.The connecting portion 21 of lamp body 2 is connected by the first fastening bolt 410 with the second brace 200.Referring to Fig. 6 to Fig. 9, connection bracket 5 has the horizontal part 50 be connected with base 3, and the vertical portion 51 vertical with horizontal part 50,3rd brace 300 of expansion bracket is connected with vertical portion 51 by the second fastening bolt 420, expansion bracket is positioned at the inner side of the vertical portion 51 of connection bracket 5, certain supporting role can also be played to expansion bracket in vertical portion 51, prevents expansion bracket from tilting laterally.
During assembling, first the 3rd brace 300 is fixed on the vertical portion 51 of connection bracket 5 by the second fastening bolt 420, the second brace 200 is fixed together with the connecting portion 21 of lamp body 2 by the first fastening bolt 410.When adjusting certain height, clamping screw 120 on the locking hole 102 only needing a telescopic unit 10 wherein, owing to being all connected by rotational pin 111 between the first brace 100, so just utilize the relation of Mechanics Vector, present the effect of Fig. 5, fastening bolt 120 will intersect mutually with upper part kills, and would not decline, reach the object of rising.The height of lamp body is increased, as long as increase the quantity of telescopic unit 10 as needed.As reduced light fixture height, only need clamping screw 120 is locked on the locking hole 102 of the telescopic unit 10 near lamp body 1, the telescopic unit of killing of then mutually intersecting be fewer, and the height of adjustment is lower.
By reference to the accompanying drawings embodiments of the invention are described above; but the present invention is not limited to above-mentioned detailed description of the invention; above-mentioned detailed description of the invention is only schematic; instead of it is restrictive; those of ordinary skill in the art is under enlightenment of the present invention; do not departing under the ambit that present inventive concept and claim protect, also can make a lot of form, these all belong within protection of the present invention.
