Abstract
The utility model discloses a lamp holder rotating structure which comprises a lamp holder casing and an adjusting shaft, wherein a shaft hole is formed in the lamp holder casing; a shaft lever of the adjusting shaft penetrates into the shaft hole and is rotationally matched with the shaft hole; and further, an elastic part for top-pressing the lamp holder casing is arranged on the shaft lever, the lamp holder casing and the adjusting shaft are mutually extruded by means of elasticity of the elastic part, friction force is produced between contacted surfaces of the lamp holder casing and the adjusting shaft, the friction force is adopted to prevent a lamp holder from rotating caused by dead weight, however, a user can overcome the friction to rotate the lamp holder by twisting the lamp holder so as to adjusting the angle of the lamp holder. The lamp holder rotating structure is not only high in reliability, but also is durable.
Description
Technical field
The utility model relates to a kind of desk lamp, particularly a kind of lamp holder rotating structure.
Background technology
Desk lamp is the standing light fixture of family, is used for illumination in the time of people's work or study.
At present, the kind of desk lamp is also a lot, but the lamp holder of part desk lamp all can not rotate, can not meet user's user demand, or the lamp holder of part desk lamp can rotate, but what adopt is that the simple hinged mode that adds screw pretension is rotated adjusting, and aforesaid way regulates reliability not high, and service life is short.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides that a kind of reliability is high, the lamp holder rotating structure of long service life.
The utility model solves the technical scheme that its technical problem adopts:
Lamp holder rotating structure, it is characterized in that: comprise shell of lamp base and regulating shaft, shell of lamp base is provided with axis hole, the axostylus axostyle of described regulating shaft penetrates in axis hole and is rotatably assorted with axis hole, and axostylus axostyle is provided with the elastic component of top pressure shell of lamp base, and the elastic force of passing through elastic component is by shell of lamp base and regulating shaft pretension.
Described axle end is provided with draw-in groove, is provided with jump ring in draw-in groove, and described elastic component is fixed on axostylus axostyle can not deviate from by jump ring.
Described elastic component middle part is evener, and evener both sides are provided with shell fragment relatively, in the middle of evener, are provided with through hole, and described axostylus axostyle is arranged in through hole, and described jump ring is by compressing and fix elastic component with evener.
Described shell fragment is V shell fragment.
In described axis hole, be provided with moving block, described axostylus axostyle is provided with the limited block of top spline motion block.
Described shell of lamp base is provided with central siphon, the endoporus that described axis hole is central siphon.
In described regulating shaft, be provided with cable-through hole.
The beneficial effects of the utility model are: this structure comprises shell of lamp base and regulating shaft, shell of lamp base is provided with axis hole, the axostylus axostyle of described regulating shaft penetrates in axis hole and is rotatably assorted with axis hole, and axostylus axostyle is provided with the elastic component of top pressure shell of lamp base, and by the elastic force of elastic component, shell of lamp base and regulating shaft are pushed and pretension mutually, between the contact-making surface of shell of lamp base and regulating shaft, produce frictional force, prevent that by frictional force lamp holder from rotating because of deadweight, and user can make lamp holder rotate to regulate lamp holder angle by the mode overcome friction of twisting lamp holder, said structure not only reliability is high, and durable.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is overview of the present utility model;
Fig. 2 is the internal structure view of the utility model lamp holder;
Fig. 3 is the three-dimensional view of shell of lamp base;
Fig. 4 is the three-dimensional view of regulating shaft.
Detailed description of the invention
Referring to figs. 1 through Fig. 4, the utility model discloses a kind of lamp holder rotating structure, comprise shell of lamp base 1 and regulating shaft 2, shell of lamp base 1 is flat tetragonal body, one side is provided with central siphon 3, the endoporus of central siphon 3 is axis hole 4, the end face of regulating shaft 2 is provided with round bar, and this round bar is axostylus axostyle 5, and axostylus axostyle 5 penetrates in axis hole 4 and is rotatably assorted with axis hole 4, extended the length of axis hole 4 by central siphon 3, thereby axis hole 4 inwalls and axostylus axostyle 5 contact-making surfaces large, thereby rotate more steadily, and stressed contact-making surface is also large, improve serviceability of structures
As shown in the figure, the end of axostylus axostyle 5 passes axis hole 4 and is positioned at shell of lamp base 1, and axostylus axostyle 5 ends are provided with draw-in groove 6, are provided with jump ring 7 in draw-in groove 6, and elastic component 11 is fixed on axostylus axostyle 5 can not deviate from by jump ring 7.Elastic component 11 concrete structures are, elastic component 11 middle parts are evener, and evener both sides are provided with shell fragment relatively, are provided with through hole in the middle of evener, described axostylus axostyle 5 is arranged in through hole, and described jump ring 7 is by compressing and fix elastic component 11 with evener, and shell fragment and shell of lamp base 1 inwall Elastic Contact, described shell fragment is preferably V shell fragment, good springiness and simple in structure, certain above-mentioned elastic component 11 also can select stage clip to replace, and above-mentioned to have reliability high, and simple, durable advantage is installed.
As shown in the figure, in described axis hole 4, be provided with moving block 8, described axostylus axostyle 5 is provided with the limited block 9 of top spline motion block 8, and in the time that lamp holder rotates, in the time turning to a certain position, moving block 8 can arrive limited block 9 in top, thereby the rotation of lamp holder is stopped.Said structure has taken into full account the safety of lamp body, because have wire to be connected between lamp holder and lamp socket, and wire is to pass by the cable-through holes 10 in the middle of regulating shaft 2, when lamp holder rotates, drives wire to rotate together, thereby avoided lamp holder inordinate rotation and wire is twisted into two parts and caused danger.
A kind of lamp holder rotating structure above the utility model embodiment being provided, be described in detail, applied specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment is just for helping to understand method of the present utility model and core concept thereof; , for one of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model meanwhile.
