The utility model further discloses a lamp adopting the double-shaft rotationally connecting mechanism. The double-shaft rotationally connecting mechanism and the lamp adopting the same have the advantages as follows: as long as the tightness degree of the screw suppressed onto the friction wheel is adjusted, the rotation tightness degree of the first shaft can be adjusted; and moreover, as the friction plate is arranged between the screw and the friction wheel, the adjustment of the tightness degree can be more smooth and stable.
Description
Technical field
The utility model relates to two rotational coupling mechanisms between the member, particularly can be around the double-axle rotation bindiny mechanism that two axial lines is rotated.The utility model also relates to the light fixture that adopts double-axle rotation bindiny mechanism.
Background technique
In many products, for example in various light fixtures, often need to adopt double-axle rotation bindiny mechanism that two members are rotatably connected, so that this rotary part can rotate around two axis with certain angle respectively.The adjusting of existing double-axle rotation bindiny mechanism ubiquity elasticity not smoothly, stable not defective, or become very tight once, or become very loose once.
The model utility content
The purpose of this utility model provides a kind of double-axle rotation bindiny mechanism that can smoothly, stably regulate the rotation elasticity.Correspondingly, the utility model also provides a kind of light fixture that adopts this mechanism.
For achieving the above object, double-axle rotation described in the utility model bindiny mechanism comprises the first member and the second component that is rotationally connected, connect by the twin shaft member between the first member and the second component, this twin shaft member is formed by fixedly connecting by the first axle and the second axle that intersection forms an angle, one end end of the second axle is fixed on the axle body section of the first axle, the first axle and the first member are rotationally connected, the second axle and second component are rotationally connected, be fixed with friction wheel at the first axle, be provided with the screw that is pressed on the friction wheel at the first member, be lined with friction pads between screw and the friction wheel.
Described double-axle rotation bindiny mechanism also can adopt following attached technological scheme.
In described the first member axle sleeve is set, the two ends of described the first axle are enclosed within the axle sleeve rotationally, consist of thus being rotationally connected of described the first axle and the first member.
The two ends of described the first axle are fixed with respectively described friction wheel, and described screw has two, respectively by being pressed on described two friction wheels.
Described two screw threads are connected on the cover plate, and cover plate is connected on the first member by other screw.
Described friction pads is silica gel pad or nylon spacer.
Be provided with the first electrode pair fitting in described the second axle, be provided with the second electrode pair fitting in described second component, when the second axle and second component were rotationally connected, the first electrode pair fitting contacted with the second electrode pair fitting.
On the other hand, the utility model also provides a kind of light fixture, and this light fixture comprises a double-axle rotation bindiny mechanism, and described double-axle rotation bindiny mechanism is the described double-axle rotation of above-mentioned any one technological scheme bindiny mechanism.
The utility model has the advantages that, by regulating by the elasticity that is pressed in the screw on the friction wheel, just can regulate the rotation elasticity of the first axle, and owing to be lined with friction plate between screw and the friction wheel, therefore can make the adjusting of elasticity more level and smooth and stable.
Description of drawings

Fig. 2 is the A-A sectional view of Fig. 1;
Fig. 3 is on the described embodiment's of Fig. 1 basis, sets up the schematic representation of electrode pair fitting;
Fig. 4 is two schematic representation that the electrode pair fitting links together shown in Figure 3.
Embodiment
Referring to Fig. 1 and Fig. 2, double-axle rotation bindiny mechanism comprises the first member 1 and the second component 2 that is rotationally connected.The concrete structure of the first member 1 and second component 2 and function are decided according to the applied actual product of double-axle rotation bindiny mechanism, for example, if double-axle rotation bindiny mechanism is applied in the track lamp, the first member 1 can be mounted in the sliding seat on the guide rail of track lamp so, and second component 2 can be to be rotationally connected phosphor screen with sliding seat.
Connect by the twin shaft member between the first member 1 and the second component 2.This twin shaft member is formed by fixedly connecting by the first axle 3 and the second axle 4 that intersection forms an angle, and an end end of the second axle 4 is fixed on the axle body section of the first axle 3.The first axle 3 of present embodiment is vertical with the second axle 4, forms "T"-shapedly, but as selectable mode of execution, the first axle 3 and the second axle 4 also can out of plumb, and concrete angle is decided according to the actual requirements.
Be enclosed within rotationally in the axle sleeve 5 at the first member 1 interior two ends that axle sleeve 5, the first axles 3 are set, consist of thus being rotationally connected of the first axle 3 and the first member 1.Have a jack 6, the second axles 4 at second component 2 and insert in this jack 6, consist of being rotationally connected of the second axle 4 and second component 2.
The two ends of the first axle 3 are fixed with respectively friction wheel 7, are provided with respectively by being pressed in 8, two screws 8 of two screws on the friction wheel 7 and two friction wheel 7 amongs are lined with friction pads 9 at the first member 1.As preferred forms, friction pads 9 preferably adopts silica gel pad or nylon spacer.Adopt this friction pads can make the adjusting of elasticity the most level and smooth, stablize.Two screws 8 are threaded on the cover plate 10, and cover plate 10 is connected on the first member 1 by other screw 11.
As further improvement, in order to make the transmission that can realize electrical signal or electric power between the first member 1 and the second component 2, also can be as shown in Figure 3 and Figure 4, at the second axle 4 the first electrode pair fitting 12 is set, at the second component 2 interior second electrode pair fittings 13 that arrange, when the second axle 4 was rotationally connected with second component 2, the first electrode pair fitting 12 contacted with the second electrode pair fitting 13, realized the transmission of electrical signal or electric power.The concrete structure of the first electrode pair fitting 12 and the second electrode pair fitting 13 is not limited to illustrated embodiment, can decide according to the realization needs.
