Specific embodiment
Below in conjunction with the attached drawing in embodiment of the present invention, the technical solution in embodiment of the present invention is carried out clear
Chu is fully described by.
Referring to figs. 1 to Fig. 2, the invention proposes a kind of lamps and lanterns of angle adjustable, including a lamp cap 100, a lamp housing 200,
Two angle boards 300 and a bracket 400.Wherein, lamp housing 200 is in the form of a column, and lamp cap 100 is fixedly installed on the end of lamp housing 200, lamp cap
100 be preferably LED light, is an anti-explosion electric torch in the present embodiment lamp cap 100 and lamp housing 200.
With further reference to Fig. 3, two angle boards 300 are fixedly installed on the two sides of lamp housing 200 respectively and are located at lamp cap
The two sides of 100 projecting directions, angle board 300 offer rotation hole 301 and multiple limiting grooves 302 far from lamp housing 200 on one side,
The rotation hole 301 of two angle boards 300 is coaxially disposed, and multiple limiting grooves 302 are radially distributed centered on rotation hole 301.
Referring to Fig. 2, bracket 400 includes placement department 410, two support rods 420, and two support rods 420 are both secured to placement department 410
And interval is oppositely arranged, support rod 420 is the flexible link that a cross sectional shape is matched with limiting groove 302, and support rod 420 is vertical
The pivot protrusion 421 matched with rotation hole 301 is convexed to form in its own extending direction, two support rods 420 bullet respectively
Property pressure holding in the limiting groove 302 of two angle boards 300, the pivot protrusion 421 of two support rods 420 is inserted in two angle boards respectively
In 300 rotation hole 301.
Placement department 410 is a U-shaped bar, and two support rods 420 are respectively arranged at the end of placement department 410, actually this implementation
In example, bracket 400 is one whole as made of the bar bending being extended continuously, and the diameter of bracket 400 is preferably 4mm.In others
Embodiment, placement department 410 or a plate, square, rotary table etc..In order to enable tool when bracket 400 is placed in a platform
There is higher stability, support rod 420 and the angle of 410 place plane of placement department are an acute angle.
Two support rods 420 need to only be opened when adjusting light angle and rotate lamp housing 200, according to actual by the lamps and lanterns
Two support rods 420 are put into corresponding limiting groove 302 by lighting demand, and lamps and lanterns adjusting illuminating lamp tool can be with free-standing exercise
Make, without specific purpose tool, can be realized the quick adjusting of lighting fixtures angle.
Referring to Fig. 4 and Fig. 5, in the present embodiment, angle board 300 is preferably a disk plate, in other embodiments
In, angle board 300 can also be a square plate.The center perforation of angle board 300 offers rotation hole 301, remote by angle board 300
The clearance space of the multiple fixed lobes 310 of face edge arranged for interval from lamp housing 200, adjacent two fixed lobe 310 forms limit
Position groove 302.Preferably, the quantity of fixed lobe 310 is 8 and is angularly uniformly distributed, and correspondingly, limiting groove 302 is 8
A, 8 limiting grooves 302 are angularly uniformly distributed, and the interval angles of adjacent limiting groove 302 are 45 °, and it is recessed that 8 limits are arranged
Slot 302 can meet the common light angle of lamp cap 100 substantially.
In order to which angle board 300 is fixed on lamp housing 200, the perforation of angle board 300 offers two fixation holes 303, and lamps and lanterns also wrap
Two screws 500 are included, lamp housing 200 of the invention is also provided with two screw holes 201 corresponding with two fixation holes 303, and screw 500 passes through
Fixation hole 303 is threadedly coupled with screw hole 201.In order to further increase the fixed effect of two screws 500, in two fixation holes 303
Heart line passes through the center of rotation hole 301.Screw 500 is a cross slotted screw, while in order to avoid screw 500 is to support rod
The interference of 520 rotations, sets a stepped hole for fixation hole 303, the head of screw 500 is contained at the step of fixation hole 303.
In other implementations, angle board 300 can also be adhered to or be snapped connection in lamp housing 200.
Preferably, the outer diameter of angle board 300 is 25mm, and with a thickness of 8mm, the diameter of rotation hole 301 is 5mm, fixation hole 303
Two bore dias be respectively 5.2mm and 2.2mm, the length of limiting slot 302 is 5mm.
Lamp housing 200 is in hexa-prism, and two angle boards 300 are respectively arranged at the two opposite cylinders of lamp housing 200.Angle board
300 diameter is no more than the width of a certain cylinder of lamp housing 200.Certainly in other implementations, lamp housing 200 can be it
His prism or cylinder, in order to install the angle board 300, need to open up on the surface of lamp housing 200 when lamp housing 200 is a cylinder
One plane notch.
Preferably, bracket 400 is made of 65Mn, and 65Mn is a kind of spring steel, after thermally treated and Cold-draw Hardening, intensity
It is higher, there is certain toughness and plasticity, in similar face state and complete through hardening, fatigue limit and alloy spring phase
When.Angle board 300 uses ADC12 die cast, and ADC12 is usually used in shell part, and ADC12 is a kind of regenerated by waste aluminum
Pack alloy, angle board 300 have effectively saved resource using ADC12.
Two angle boards 300 are fixed on lamp housing 200 first in assembly by the lamps and lanterns of angle adjustable of the present invention, then will branch
Two support rods 420 of frame 400 open, and the pivot protrusion 421 of support rod 420 is aligned to the rotation hole 301 of angle board 300, is being propped up
Under the lateral elastic force effect of strut 420, in the insertion rotation hole 301 of pivot protrusion 421, and support rod 420 is dialled in accordingly
In limiting groove 302.
It opens two support rods 420 when adjusting the angle with Fig. 6, the lamps and lanterns of angle adjustable of the present invention referring to Fig.1 and to support
Bar 420 deviates from limiting groove 302, but pivot protrusion 421 is still located in rotation hole 301, then rotates lamp housing 200, will support
Bar 420, which is put into corresponding limiting groove 302, can be completed the adjustment of lighting fixtures angle.
The above is a preferred embodiment of the present invention, it is noted that for those skilled in the art
For, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also considered as
Protection scope of the present invention.
