The specific embodiment
For technical characterictic of the present invention, object and effect being had more clearly, understand, now contrast accompanying drawing and describe the specific embodiment of the present invention in detail.
As shown in Figure 1, be an embodiment provided by the invention, a kind of lighting device, comprising: light fixture 1 and rotate the support 2 being arranged on light fixture 1 by rotating shaft 4.For locking rack 2 and light fixture 1, as shown in Figure 1, on support 2, be provided with the first engagement line 21, on light fixture 1, be provided with and engage the second engagement line 11 that line 21 coordinates with first.As shown in Figure 2 and Figure 3, support 2 activities are assemblied in rotating shaft 4 and the both ends of rotating shaft 4 pass support 2, that is: between the through hole on rotating shaft 4 and support 2, be matched in clearance, and support 2 rotates and also can move along the axial reciprocating of rotating shaft 4 along the tangent line of rotating shaft 4 simultaneously.One end of rotating shaft 4 is fixedly installed on light fixture 1, the hinged pulling piece 6 that is provided with in the other end, the angle capable of regulating forming between pulling piece 6 and rotating shaft 4.Concrete, as shown in Figure 4, pulling piece 6 comprises that Eccentric-hinge is connected on hinged end 61 in rotating shaft 4 and for introducing the free end 62 of external force, by adjusting free end 62, drives hinged end 61 in bias hinged major axis position or minor axis location.Hinged end 61 and rotating shaft 4 is eccentric, and hinged this structure is set is the displacement difference between major axis and the minor axis in order to utilize hinged end 61, as shown in Figure 2, when hinged end 61 is positioned at major axis position, hinged end 61 props up support 2 to make described the first engagement line 21 engage line 11 engagement with described second fixing, to support 2, provides and locates to prevent that the first engagement line 21 from engaging line 11 with second and departing from; As shown in Figure 3, when minor axis location, between support 2 and hinged end 61, there is certain interval in hinged end 61, now can along rotating shaft 4 move axially support 2, make the first engagement line 21 engage line 11 with second and depart from, then can carry out the adjustment of the relative position of support 2 and light fixture 1.
Concrete, as Figure 1 and Figure 4, on hinged end 61, eccentric setting has through hole 611, rotates and be provided with a bearing pin 5 with groove 51 in through hole 611, and rotating shaft 4 through-going recess 51 are also fixed on bearing pin 5, and hinged end 61 can rotate to an angle around bearing pin 5.Understandable, the longitudinal section of hinged end 61 can be regular shape, as: circular or oval, when longitudinal section is circular, through hole 611 is arranged on non-central some place, when longitudinal section is oval, through hole 611 can be arranged on central point, also can be arranged on non-central some place; Hinged end 61 can be also irregularly shaped, and through hole 611 can need to arrange according to the position of major axis and minor axis.
Further, on the basis of technique scheme, for the ease of relatively rotating of hinged end 61 and rotating shaft 4, as shown in Figure 4, on hinged end 61, depression is provided with to hold the slot to make way 63 of rotating shaft 4, and in the both sides of slot to make way 63, through hole 611 is set respectively, for fixed pin shaft 5, bearing pin 5 forms spatial vertical relation with rotating shaft 4.
Under industrial environment, vibrate sustainable existence, pulling piece 6 turns to while propping up support 2, as shown in Figure 2, lasting vibration may make free end 62 rotate, and the position of hinged end 61 changes thereupon, thereby make support 2 lose the support force of hinged end 61, light fixture 1 is in active state, and vibration can aggravate rocking of light fixture 1, causes light fixture 1 rotating shaft 4 that comes off, even can cause falling of light fixture 1, cause potential safety hazard, same, if pulling piece 6 turns to position as shown in Figure 3, between support 2 and light fixture 1, it is active state, due to the gravity of pulling piece 6 self, free end 62 has the trend clockwise rotating, thereby destroy this active state between support 2 and light fixture 1, therefore, on the basis of technique scheme, for pulling piece 6, under two states, locate unstable defect, carried out technological improvement, as Fig. 1, Fig. 2, shown in Fig. 3, in rotating shaft 4, suit is provided with an elastic component, in order to resiliency supported bearing pin 5, one end butt support 2 of elastic component, the other end is connected on bearing pin 5.Under two states, elastic component is all the time in compressive state as shown in Figure 2 and Figure 3.
Understandable, elastic component also can not be sleeved in rotating shaft 4, and the two ends of elastic component are welded respectively or are hooked on support 2 and bearing pin 5.
Preferably, as shown in Figure 1, this elastic component is a spring 3.
It is interior engagement fit that the first engagement line 21 and second engages between line 11, and intermeshing teeth (that is: the first engagement line 21 or the second engagement line 11) can be straight-tooth, helical teeth, circular cone tooth.Straight-tooth coordinates the grafting that can facilitate between support 2 and light fixture 1, and helical teeth and circular cone tooth can make interlock between support 2 and light fixture 1 obtain tighter.
On the basis of technique scheme, for the ease of pulling piece 6, contact and prop up support 2, avoid naked being exposed on the external of hinged end 61 of pulling piece 6 simultaneously, for hinged end 61 provides spacing in certain space, as shown in Figure 1, on support 2, be provided with one for holding the host cavity 22 of hinged end 61.Host cavity 22 is suitable with hinged end 61, and more bigger than hinged end 61, and hinged end 61 can be contained in host cavity 22 in rotation process, and hinged end 61 is just connected to the inwall of host cavity 22 while turning on long axis direction as shown in Figure 2.
For the ease of the installation and removal of light fixture and support, preferred, as shown in Figure 1, rotating shaft 4 is fixed on light fixture 1 by threaded engagement.Understandable, rotating shaft 4 also can realize fixing with light fixture 1 by welding or other modes.
Preferably, in order to coordinate with rotating shaft 1, as shown in Figure 1, be provided with a nut (scheming not shown) in light fixture 1, nut is arranged in axis hole 12, and the end of rotating shaft 4 is provided with the external screw thread 41 coordinating with nut.
By reference to the accompanying drawings embodiments of the invention are described above; but the present invention is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment is only schematic; rather than restrictive; those of ordinary skill in the art is under enlightenment of the present invention; not departing from the scope situation that aim of the present invention and claim protect, also can make a lot of forms, within these all belong to protection of the present invention.
