A kind of lamp electric appliance box governor motion
Technical field
The utility model relates to a kind of light fixture corollary apparatus, and more particularly, it relates to a kind of lamp electric appliance box governor motion.
Background technology
These small-sized light fixtures of shot-light, LED illumination lamp have extensive application in venue of performing, market show window, workshop, public place of entertainment and even average family, this type of light fixture existing generally can carry out lamp holder towards adjustment, to improve the illumination of regional area, adapt to the needs of the aspects such as displaying, work or life better, some occasion even also needs mounting guide rail, to carry out the longer distance translation of light fixture entirety if desired.On this type of light fixture common a kind of towards adjusting device be the adjusting bracket of U-shaped, lamp holder is rotatably connected in the opening of adjusting bracket, realize angle by the frictional force between lamp holder and adjusting bracket to fix, and the frictional force size between lamp holder and adjusting bracket is determined by the dynamics that is critical of the securing member between lamp holder and adjusting bracket completely, securing member is locked too tight then lamp holder rotation adjustment has some setbacks, also easily accelerate the wearing and tearing between lamp holder and adjusting bracket, securing member lock get Tai Song is difficult to again to realize angle to be fixed, and very easily there is looseness between lamp holder and adjusting bracket after adjustment repeatedly, and must regularly again lock.Therefore there is use inconvenience, the problem of poor reliability in existing shot-light, LED illumination lamp.Publication number is that the utility model of CN201437918U discloses a kind of rail-type LED projection lamp on April 14th, 2010, be arranged on guide rail, comprising there being a track box be connected with above-mentioned slide, this track box is connected with lamp body back seat by angular adjustment frame, and this lamp body back seat lower end is fixedly connected with light source holder.Compared with prior art, this utility model can realize LED projection lamp at radial 350 degree by installing an angular adjustment frame on LED projection lamp lamp body, and axially the scope of 85 is interior rotates arbitrarily.Simultaneously by LED light source being arranged between light source holder and reflection shield, the conduction of heat during LED luminescence can be accelerated, avoid most of heat to hoard in luminous site, effectively solve the heat dissipation problem of LED projection lamp.But this utility model is also by keeping the degree of tightness dynamics between lamp body and angular adjustment frame to realize the angle adjustment of lamp body, therefore also can loosen unavoidably, cannot the problem such as fixed angle.
Utility model content
There is use inconvenience in existing adjustable shot-light, LED illumination lamp, the defect of poor reliability, for overcoming these defects, the utility model provides one more conveniently can carry out the adjustment of light fixture irradiating angle, and more reliably keeps light fixture to regulate the lamp electric appliance box governor motion of rear attitude.
The technical solution of the utility model is: a kind of lamp electric appliance box governor motion, comprise electrical appliance kit, also comprise electrical appliance kit support, electrical appliance kit support is provided with screw rod and electrical appliance kit carrier, screw rod fixed mount is located on electrical appliance kit support, and electrical appliance kit carrier is threadedly connected on screw rod, and electrical appliance kit carrier base is provided with chute, electrical appliance kit is slidably connected in chute, and screw rod is provided with axial location nut.By this lamp electric appliance box governor motion, both can translation electrical appliance kit position, electrical appliance kit carrier can be made again around bolt rotary, thus change electrical appliance kit and even be arranged on position and the inclination angle of the lamp holder on electrical appliance kit, obtain desirable direction of illumination, after changing the angle of inclination of electrical appliance kit, push against electrical appliance kit carrier with axial location nut, the frictional force between electrical appliance kit carrier and screw rod can be increased, keep the angle of inclination of electrical appliance kit carrier.Compared to existing extrusion friction type adjusting bracket, the adjustment of mechanism is more convenient, more steady, and the light fixture attitude after adjustment keeps more reliable.
As preferably, electrical appliance kit support is c-shaped, and comprise a top board and two end plates, two ends panel is connected in top board two ends, and screw rod two ends are connected on two end plates.This electrical appliance kit contoured cradle is relatively regular, easily makes, force structure balance and stability.
As preferably, electrical appliance kit carrier comprises square tube body, square nut block and rectangular tube plug, square nut block and rectangular tube plug are plugged on square tube body two ends respectively, chute is along the axis side of the being located at its bottom of square tube body, square nut block is connected with screw flight, the cavity that one end is open is established in rectangular tube plug, the blind end of rectangular tube plug is rotatably connected on electrical appliance kit support, screw rod one end is connected on end plates, and screw rod other end adaptation is inserted in the cavity of rectangular tube plug.This kind of electrical appliance kit carrier structure is comparatively simple, and component processing is easy, easy to assembly, electrical appliance kit carrier is connected and screw rod and being connected in technique of electrical appliance kit support are all easy to realize with screw flight.
As preferably, square nut block and rectangular tube with plug all with square tube body interference fit.By interference fit, square nut block, rectangular tube plug and square tube body are connected as a single entity and form electrical appliance kit carrier, structure is simple, easy to assembly.
As preferably, the opposite face of two end plates sets firmly respectively one and fix dististyle, fixing dististyle center is provided with centre bore, and screw rod stiff end welds with corresponding fixing dististyle, and the blind end of rectangular tube plug passes the centre bore of corresponding fixing dististyle.Screw rod is first connected with fixing dististyle, forms a sub-unit structure, then by this sub-unit and electrical appliance kit support integrated, can efficiency of assembling be improved man-hour adding.
As preferably, the blind end end of rectangular tube plug is provided with axle snap ring, and axle snap ring is positioned at outside the fixing dististyle corresponding with rectangular tube plug.Screw rod, rectangular tube plug can be connected on fixing dististyle by axle snap ring, form the sub-unit structure be made up of screw rod, electrical appliance kit carrier and fixing dististyle.
The beneficial effects of the utility model are:
Light fixture adjusting range is large.In the utility model, electrical appliance kit both can along screw axial translation, again can around bolt rotary, can at two enterprising Row sum-equal matrix of dimension, and adjustable range is larger.
Light fixture adjustment is more convenient.During inclination angle by the utility model adjustment light fixture, only need normal turn on screw rod, coordinating tightness without the need to considering between lamp holder with peripheral support part, adjusting more convenient.
After light fixture adjustment, attitude keeps reliability higher.The utility model is after the adjustment of electrical appliance kit completes, can by axial location nut to screw rod or electrical appliance kit carrier in addition locking, thus keep the attitude after light fixture adjustment, relative to prior art, the utility model keeps the reliability of the rear attitude of light fixture adjustment higher.
