Abstract
A rotating head fixed structure for lighting apparatus comprises a lamp shield and a lamp stand. An axial portion is positioned on one end of the lamp stand, the axial portion is pin jointed to a ledge on one end of the lamp shield, the ledge is provided with some polygonal perforation, and a polygonal assembly is built in the polygonal perforation. An interlocking assembly traverses the polygonal assembly and the axial portion and the surface of the polygonal assembly moves relatively towards the lateral surface of the axial portion, forming a frictional resistance that can be adjusted easily, thereby avoiding the loosening of the axial portion and the polygonal assembly, making the lamp shield and the lamp stand joints together fixedly.
Description
Technical field
The utility model provides a kind of fitting structure, especially a kind of lampshade and lamp stand pin-jointed structure.
Background technology
General known light fixture is constituted (as shown in Figure 6) by lamp stand 1a and the lampshade 2a that is movably set in lamp stand 1a one end, the end of this lamp stand 1a has axial region 11a, has axis hole 12a on this axial region 11a, and the ora terminalis of this lampshade 2a has the lug 21a that articulates with lamp stand 1a one end, this lug 21a has the hole 22a corresponding with axis hole 12a respectively, and with the screw rod 3a that has been threaded among hole 22a and the axis hole 12a, the termination of this screw rod 3a has been closed nut 4a, and between the screw head 31a and the lug 21a outside and the outside of nut 4a and another lug 21a is respectively equipped with pad 5a.Thus, can make this lampshade 2a utilize the screw rod 3a that is threaded among hole 22a and the axis hole 12a, reach the cover firing angle degree of adjusting lampshade.
Though above-mentioned known light fixture utilizes screw rod 3a mating holes 22a and axis hole 12a to make the adjustment that lampshade 2a can upper and lower angle on lamp stand 1a.But, because this screw rod 3a only is arranged among hole 22a and the axis hole 12a as pivot with the cooperation of nut 4a and metallic gasket 5a, therefore when lampshade 2a adjusts upper and lower angle, because metallic gasket 5a and nut 4a interlocking are in the lug 21a outside, when lampshade 2a rotated, this promptly drove lug 21a action, and this moment, this metallic gasket 5a will be along with lug 21a rotates, perhaps along with the rotation (21a turn 90 degrees as lug, and this metallic gasket 5a only rotates 10 degree) slightly of lug 21a do.In use for some time, easily cause becoming flexible between screw rod 3a and nut 4a and metallic gasket 5a, cause between lampshade 2a and lamp stand 1a loosening, make lampshade 2a be difficult for adjusting, this moment, the user can utilize instrument again with screw rod 3a and nut 4a locking, allow between lampshade 2a and lamp stand 1a no longer loosening, but after screw rod 3a locks, cause difficult adjustment of lampshade 2a maybe can't adjust again, so cause user's inconvenience in the use.
The utility model content
In order to solve above-mentioned disappearance, avoid disappearance to exist, main purpose of the present utility model, be to provide a kind of swivel head fixed structure of light fixture, by lampshade and lamp stand pin-jointed structure are redesigned, when lampshade adjustment cover firing angle is spent, make pin-jointed structure be formed with frictional resistance, it is any loosening to allow lampshade and lamp stand be difficult for producing.
In order to reach above-mentioned purpose, the utility model provides a kind of swivel head fixed structure of light fixture, comprising:
Lamp stand, the one end is provided with axial region, and this axial region has two sides;
Lampshade, the one end is provided with group connecting part, and this group connecting part is provided with the lug that articulates with axial region, has the polygon perforation on this lug;
Two polygon assemblies are arranged in the above-mentioned polygon perforation, and the surface of this two polygons assembly contacts clamping with above-mentioned axial region two sides;
The interlocking assembly, interlocking is in above-mentioned polygon assembly and axial region;
Wherein, when adjusting with lampshade, the side relative motion of the surface of this polygon assembly and axial region is formed with frictional resistance, makes to be difficult between lampshade and lamp stand becoming flexible.

The specific embodiment
Relevant technology contents of the present utility model and detailed description, existing conjunction with figs. is described as follows:
See also Figure 1 and Figure 2, be respectively light fixture stereoscopic figure of the present utility model and lamp stand and lampshade exploded view.As shown in the figure, the utility model is a kind of swivel head fixed structure of light fixture, and it is made of base 1, lamp stand 2 and lampshade 3, when adjusting lampshade 3 rotations on lamp stand 2, make the lampshade 3 and the pin-jointed structure of lamp stand 2 produce frictional resistance, make 2 of lampshade 3 and lamp stands be difficult for producing loosening.
The above-mentioned lamp stand of carrying 2 one ends are movably arranged on the base 1, and the other end of this lamp stand 2 is provided with axial region 21, and the centre of this axial region 21 has axis hole 211 and two sides 212.
The ora terminalis of this lampshade 3 is provided with and the above-mentioned axial region 21 movable group connecting parts 31 that engage, these group connecting part 31 windings are on the lug 311 of axial region 21 both sides, this lug 311 has polygon perforation (as blossom type or octagon) 312, be provided with polygon assembly 32 in this polygon perforation 312, be provided with hole 321 in this polygon assembly (as blossom type or octagon) 32, pass for interlocking assembly (screw rod) 33, and pass the axis hole 211 of axial region 21 and hole 321 interlockings of another polygon assembly 32, utilize the surface 322 of two polygon assemblies 32 to contact and clamping with axial region 21 two sides 212, when making surface 322 relative motions of side 212 corresponding polygon assemblies 32 of axial region 21, to be formed with frictional resistance, it is any loosening to make 2 of lampshade 3 and lamp stands be difficult for producing.
See also Fig. 3 and shown in Figure 4, be respectively the lampshade of Fig. 1 and the cutaway view and the adjustment action diagram of lamp stand articulated section.As shown in the figure, when the user adjusts lampshade 3 according to required irradiation angle, allow lug 311 with lampshade 3 synchronization actions, the polygon lug 311 in was bored a hole and 312 promptly to be driven polygon assembly 32 and interlocking assembly 33 along with synchronization action, to reach the adjustment of lampshade 3 irradiation positions this moment.
In adjusting lampshade 3 processes, this polygon assembly 32 is driven along with lug 311 with interlocking assembly 33 and is rotated synchronously, allow the surface 322 of polygon assembly 32 produce corresponding motion and to form frictional resistance with 212 of the sides of axial region 21, this frictional resistance makes the surface 322 of polygon assembly 32 and the side 212 of axial region 21 not produce skidding, therefore after adjustment, 2 of this lampshade 3 and lamp stands can not produce any problem such as loosening, and the user also can adjust the irradiating angle of lampshade 3 easily.
See also shown in Figure 5ly, be another embodiment schematic diagram of the present utility model.As shown in the figure, the shape of polygon assembly 32 of the present utility model, except for the above-mentioned blossom type of carrying or octagon, can also be the polygon assembly 32 of hexangle type, allow 212 of the sides of surface 322 and axial region 21 of polygon assembly 32 of this hexangle type produce corresponding motions and to form frictional resistance, this frictional resistance makes the surface 322 of polygon assembly 32 and the side 212 of axial region 21 not produce skidding, therefore after adjustment, 2 of this lampshade 3 and lamp stands can not produce any problem such as loosening, and the user also can adjust lampshade 3 easily.
In addition, pin-jointed structure of the present utility model can also be able to be used on the pin-jointed structure of lamp stand 2 and lamp stand 2 except the pivot joint that can be used in lampshade 3 and lamp stand 2.
