The specific embodiment
The light fixture partial sectional view of the lamp holder rotary positioning structure of employing preferred embodiment of the present invention as shown in Figure 1, consult Fig. 2, Fig. 3 and Fig. 4 simultaneously, lamp holder rotary positioning structure wherein comprises connecting rod 3, the first stay 4, the second stay 5 and locking member 6, one end of connecting rod 3 is fixedly connected with lamp holder 2, and the other end is located on light fixture handle 1, and at this connecting rod 3, passes the locking member 6 that is provided with adjustable tightness on one end of light fixture handle 1.At the middle part of connecting rod 3, be arranged with the first stay 4 and the second stay 5 that is connected light fixture handle 1 that connect lamp holder 2.On the first stay 4, be provided with the first serrated face 42, on the second stay 5, be provided with the second serrated face 52 being meshed with the first serrated face 42 simultaneously, with the different angles that regulate lamp holder 2 to rotate.When unclamping locking member 6, light fixture handle 1 is releasing orientation with lamp holder 2, drives the first stay 4 and the second stay 5 to separate, now can rotary lamp holder 2, be adjusted to suitable position; After lamp holder 2 location positionings, can the first stay 4 and the second stay 5 be compressed by locking member 6, stop lamp holder 2 to rotate relative to light fixture handle 1.
In the present embodiment, because connecting rod 3 one end are fixedly connected with lamp holder 2, the other end is located on light fixture handle 1, and lamp holder 2 can rotate within the scope of 360 ° relative to light fixture handle 1 together with connecting rod 3.And by the serrated face on the first stay 4 and the second stay 5, lock, can guarantee stability when lamp holder 2 is fixedly, and easy to adjust, fitting operation is simple and reliable, mounting means can property row and the ability of suitable environment better.
Preferably, the first stay 4 in above-described embodiment and the second stay 5 all adopt the elastomeric material that deformation can occur to make, and the first serrated face 42 and the second serrated face 52 are the concave surface that edge is high, middle part is low.Can, by regulating locking member 6 to control the mesh degree of the first stay 4 and the second stay 5, realize lamp holder 2 adjusting angle is installed freely.When needs regulate lamp holder 2 setting angle, locking member 6 can be unclamped to suitable position, make the first serrated face 42 and the second serrated face 52 by the sawtooth phase interlock at edge, what operator can overcome that edge sawtooth interlock produces carrys out rotary lamp holder 2 compared with less friction, this frictional force can play certain position-limiting action to lamp holder 2, prevent that lamp holder 2 from arbitrarily rotating, thus convenient adjusting.Until lamp holder 2 is adjusted to behind suitable position, again by locking member 6 lockings, light fixture handle 1 drives the second stay 5 to draw close to the first stay 4, there is under pressure elastic deformation in the first stay 4 and the second stay 5, thereby the first serrated face 42 and the second serrated face 52 are fitted completely, increase by the first stay 4 and rotate the required resistance overcoming relative to the second stay 5, play the effect that stops lamp holder 2 arbitrarily to rotate relative to light fixture handle 1.
In above-described embodiment, the elastomeric material that deformation can occur preferably adopts acetal resin to make.Due to acetal resin, there is the performances such as good resistance to solvent, wearability, oil resistant class, weak acid resistant, self lubricity, weak base, and have very high hardness, rigidity and plasticity.Therefore can meet the first stay 4 and the second stay 5 frictional force that required prevention lamp holder 2 arbitrarily rotates when relatively rotating, can also meet when lamp holder 2 is locked on light fixture handle 1 simultaneously, the first stay 4 and the second stay 5 produce deformation, so that the demand that the first serrated face 42 and the second serrated face 52 are fitted completely, the stability when can farthest guarantee the reliability in lamp holder 2 adjustment processes and locking.
Preferably, the thickness of the first stay 4 and the second stay 5 reduces gradually from edge to centre, the first serrated face 42 and the second serrated face 52 are all slope shape from edge to centre, and the teeth on the first serrated face 42 and the second serrated face 52 by center outwards all radially.When there is elastic deformation under pressure in the first stay 4 and the second stay 5, teeth on the first serrated face 42 and the second serrated face 52 gradually interlock are lived, increase by the first stay 4 and rotate the required resistance overcoming relative to the second stay 5, play the effect that prevents that lamp holder 2 from arbitrarily rotating relative to light fixture handle 1.
The first stay 4 in above-described embodiment and the second stay 5 also can adopt the material that can not produce deformation to make, for example die casting aluminium.Adopt this can not produce after shape-changing material, in the time of need to regulating lamp holder 2 setting angle, need locking member 6 to unclamp as far as possible, the first stay 4 and the second stay 5 are separated, then rotary lamp holder 2, be adjusted to behind suitable position, then by locking member 6 lockings, made the edge phase interlock of the first serrated face 42 and the second serrated face 52.Because the first stay 4 and the second stay 5 all can not produce deformation, therefore the interlock at two serrated face edges is enough to guarantee the locking positioning of lamp holder 2 on light fixture handle 1.
In a further embodiment, the first stay 4 can be fixedly installed on lamp holder 2, in the present embodiment by the common fixed form in this area, as shown in Figure 2, above-mentioned connecting rod 3 is provided with external screw thread, is provided with screw 21 on lamp holder 2, and connecting rod 3 one end and screw 21 are spirally connected.On the first stay 4, being correspondingly provided with internal thread hole 41, the first staies 4 that match with external screw thread on screw rod is fixedly connected with lamp holder 2 by screw rod.This first stay 4 can be movable together along with lamp holder 2, when regulating locking member 6, can regulate the spacing of the first stay 4 and the second stay 5.
In a further embodiment, the first stay 5 can be fixedly installed on light fixture handle 1 by the common fixed form in this area, in the present embodiment, on the second stay 5, fixing hole 53 is set, by being directly connected on lamp holder 2 and being fixedly connected on light fixture handle 1 by screw through the screw (not shown) of this fixing hole 53, and on the second stay 5, be provided with and be convenient to the through hole 51 that connecting rod 3 passes.When locking member 6 regulates, the second stay 5 can be along with light fixture handle 1 moves relative to screw rod together, to regulate the spacing with the first stay 4.
Preferably, in the various embodiments described above, locking member 6 adopts structure wing nut as shown in Figure 5.
More preferably, as shown in Figure 3, the first stay 4 outer surfaces in the various embodiments described above are set to polygonal, as hexagon, octagonal etc., to facilitate, it are connected on screw rod by instrument.
In another embodiment of the present invention, a kind of light fixture is also provided, as shown in Figure 6, comprise light fixture handle 1 and lamp holder 2, wherein, lamp holder 2 is fixed on light fixture handle 1 by the lamp holder rotary positioning structure 7 as in aforementioned arbitrary embodiment.Detailed description about lamp holder rotary positioning structure 7 can, referring to aforementioned each embodiment, not repeat them here.
Should be understood that, for those of ordinary skills, can be improved according to the above description or convert, and all these improvement and conversion all should belong to the protection domain of claims of the present invention.
