The specific embodiment
Below in conjunction with diagram, the preferred embodiments of the present invention are described in detail.
The lamp fixing device structural representation of the scalable irradiating angle of preferred embodiment of the present invention is as shown in Figure 1; Consult Fig. 2,3 and 4 simultaneously; Said lamp fixing device comprises and is used to connect the holder 10 of lamp holder and is installed in holder 10, has first adjustment disk 20 of first serrated face 21.This lamp fixing device also comprises second adjustment disk 30 with second serrated face 31; Have the teeth that to match on first serrated face 21 and second serrated face 31; Relative teeth can complement each other to form a plurality of gears, fix on different irradiating angles with the Lock with lighting means that will be fixed on the holder 10.Second adjustment disk 30 is fixed on the adjustment disk fixed mount 32, also can be connected on other fixture.One regulates bolt 40 passes second adjustment disk 30, first adjustment disk 20 and holder 10 successively; The end that adjusting bolt 40 passes holder 10 is provided with nut 42; Be reserved with gap 43 between nut 42 and the holder 10, be provided with the spring 50 that is used to hold holder 10 and first adjustment disk 20, first serrated face 21 and second serrated face 31 are fitted at these 43 places, gap.
When the needs adjusting is connected the irradiating angle of the lamp holder on the holder 10, only need vertically pull lamp holder or holder 10, first adjustment disk 20 that is connected on the holder 10 rotates around regulating bolt 40 together; And second adjustment disk 30 is fixed, and the teeth on second serrated face 31 of first serrated face 21 that is adjusted to first adjustment disk 20 and second adjusting 30 are relative, and first adjustment disk 20 and holder 10 are applied along regulating bolt 40 axial outside active forces; Make first adjustment disk 20 and holder 10 compress spring 50 together; And being retracted into 43 places, gap, this moment, first adjustment disk 20 can rotate by relative second adjustment disk 30, regulated the irradiating angle that is fixed on the lamp holder on the holder 10 arbitrarily; When waiting to be adjusted to the position that needs; Unclamp lamp holder or holder 10, spring 50 returns back to former length, because the teeth of first adjustment disk 20 and second adjustment disk 30 are all at right angles trapezoidal; And the minor face of right-angled trapezium is positioned at the outside of first adjustment disk 20 and second adjustment disk 30; Therefore first adjustment disk 20 is easily along the slip of taking advantage of a situation of the hypotenuse of right-angled trapezium, matches with teeth on second adjustment disk 30, makes the lamp holder position be able to fix.
In a further embodiment; The lamp fixing device of scalable irradiating angle is except comprising the described structure of front embodiment, and is as shown in Figure 4, and spring 50 wherein is to be set in to regulate on the bolt 40; Holder 10 is provided with and is used to pass the hole 121 of regulating bolt 40; Hole 121 madial walls have a step surface 122, and spring 50 1 ends hold on nut 42, and the other end holds on step surface 122.Compare with directly being fixed on spring 50 on the holder 10 or being fixed on to regulate on the bolt 40; Spring 50 is set in to regulate on the bolt 40 can saves fixed structure, and it is evenly stressed only need to adopt a spring 50 just can make between adjusting bolt 40 and the holder 10.
In a further embodiment; As shown in Figure 2; The lamp fixing device of scalable irradiating angle is except comprising the described structure of front embodiment, and holder 10 wherein comprises that adjustable pipe 11 and adjustable pipe holder 12, the first adjustment disks 20 all are fixedly connected on the adjustable pipe holder 12 with adjustable pipe 11; And the axial and adjustable pipe 11 of first adjustment disk 20 is axially perpendicular; Specifically can adjustable pipe 11 be plugged in the adjustable pipe holder 12 from top to bottom like Fig. 2, shown in 3 and 4, more laborsaving when pulling lamp holder and regulate irradiating angle like this.
Among the above embodiment, the frictional force when reducing to relatively rotate between first adjustment disk 20 and second adjustment disk 30, holder 10 and gap 43 distances of regulating between the bolt 40 are preferably greater than the teeth degree of depth on first serrated face 21 and second serrated face 31.Like this teeth on two serrated faces relatively, first adjustment disk 20 and holder 10 are applied when regulating the axially outside active force of bolt 40, first adjustment disk 20 has enough spaces to retreat, and makes angular adjustment lighter.
Among the above embodiment, regulate bolt 40 and also can adopt other structure to substitute with said function.As shown in Figure 1, in order to make whole lamp fixing device more attractive in appearance, nut 42 is provided with decorates knob 41, regulates the part that bolt 40 exposes to block.
Among the above embodiment; As shown in Figure 2; The teeth of first adjustment disk 20 and second adjustment disk 30 are arranged on the marginal portion of first serrated face 21 and second serrated face 31 radially; But not whole serrated face is enough to form a plurality of gears like this, and can save technology and reduce by first adjustment disk 20 and second adjustment disk 30 between frictional force.
Shown in Fig. 2 and 4; Regulate bolt 40 and pass center on first adjustment disk 20 and second adjustment disk 30; Place near the center on first adjustment disk 20 concaves; So that the screw that connects holder 10 is set under the situation that does not influence the interlock of teeth phase, the place near the center on second adjustment disk 30 concaves, so that the screw that connects adjustment disk fixed mount 32 is set under the situation that does not influence the interlock of teeth phase.
Another embodiment of the present invention also provides a kind of light fixture; As shown in Figure 5; Consult Fig. 1 simultaneously, it comprises lamp holder (not shown), and lamp holder is fixed on the lamp holder fixed mount 60; Also comprise the lamp fixing device of the scalable irradiating angle described in the arbitrary embodiment in front, lamp holder is fixedly connected on the holder 10 through lamp holder fixed mount 60.Through pulling lamp holder or holder 10, first adjustment disk, 20 relative second adjustment disks 30 are rotated, to regulate the irradiating angle of lamp holder, concrete Principles of Regulation can be referring to the description among the embodiment of front.
The lamp fixing device of scalable irradiating angle of the present invention is fitted under the elastic force of spring 50 through the serrated face that adopts first adjustment disk 20 and second adjustment disk 30 each other; And rotate first adjustment disk 20 through external force and overcome elastic force separately behind two adjustment disks; Overcome again between two adjustment disks than less friction, be rotatably connected to the holder 10 of lamp holder, regulate the irradiating angle of lamp holder; After being adjusted to the precalculated position; Unclamp holder, two adjustment disks are coincide once more, the fixed position of locking lamp holder.
Adopt lamp fixing device of the present invention not only can regulate the irradiating angle of lamp holder easily through one hand, and when holder connects the bigger lamp holder of weight, also can the reliable adjustment irradiating angle.
Should be understood that, concerning those of ordinary skills, can improve or conversion, and all these improvement and conversion all should belong to the protection domain of accompanying claims of the present invention according to above-mentioned explanation.
