The improvement has a structure which is as follows: the supporting arm is fixed with a beating track with a preset shape, the beating track is provided with an arc track groove and a clamping handle which is fixed at an appropriate place of the spiral arm and can move along the track of the arc track groove in order to control the beating angle of the spiral arm, the spiral arm can be controlled and fixed at the needed beating angle at will by the fixation of the clamping handle and the beating track. Therefore, the beating angle of the spiral arm can be adjusted easily to control the illuminating position of the lamp body, the spiral arm can be supported and fixed more stably and firmly and the beating does not loosen.
Description
Technical field
The utility model is relevant with a kind of light fixture, more detailed it, be meant a kind of light fixture spiral arm beat control device especially, can provide spiral arm more to stablize firm support fixation effect.
Background technology
Generally can adjust the light fixture of lighting position and angle, roughly all have a support arm and a spiral arm; Wherein, this support arm can be assembled and be fixed on the pedestal, be placed on desktop or the table top by pedestal, form a vertical light fixture, this support arm also can directly be assembled and be fixed on the predetermined metope, form a wall-hanging light fixture, this spiral arm then can directly or indirectly be assembled the lamp holder of a tool lamp body and lampshade, and simultaneously, this support arm and spiral arm are adopted the pivot design, make spiral arm can do the deflection angle adjustment, and then the light angle and the position of control lamp holder.What need special instruction is, for spiral arm being fixed in a certain deflection angle, as shown in Figure 7, known light fixture is to be folded with a rubber washer 3 between the relative positions that support arm 1 and spiral arm 2 articulates mutually, and by the locking packing of a packing bolt 4, make rubber washer 3 that the anti-slip effect of suitable size is provided, to produce beats loosening to prevent to adjust spiral arm 2 after the angle.
But, though this rubber washer 3 has the friction anti-slip effect of certain degree, but because such structural design, can make spiral arm 2 hold suffered gravity effect in addition, converting torsional moment fully to acts on the rubber washer 3, make rubber washer 3 must bear great torsional moment, add that this rubber washer 3 belongs to elastomeric material, its material behavior produces embrittlement and plastic deformation easily in use for some time, therefore make this rubber washer 3 in use for some time, its friction anti-slip effect just can reduce fast, cause spiral arm 2 to be supported effectively with fixing, and it is loosening to be easy to generate beat, relatively, this light fixture also can't remain in light angle and the position that the user was adjusted originally with being stabilized, and its illuminating effect is had a greatly reduced quality naturally.So, how to improve at the beat fixture construction of known light fixture spiral arm, truly have its necessity.
The utility model content
The utility model main purpose is to provide a kind of light fixture spiral arm beat control device, wish to make the spiral arm of light fixture to obtain more to stablize firm support fixation effect, to improve known spiral arm after use a period of time, be easy to generate the shortcoming of loosening beat, and reach lasting, stable good illumination effect.
For reaching above-mentioned purpose, the utility model light fixture spiral arm beat control device has following formation:
This light fixture spiral arm beat control device comprises: a support arm has one first end and one second end; One spiral arm has one first end and one second end; One lamp body, assembling is fixed on second end of spiral arm; One beat track is fixed in this support arm book office, which is provided with a curved track groove; One lock handle, this spiral arm book office is fixed in assembling, can do arc guiding displacement along the curved track groove of beat track, and can optionally be fixed in the relative position of beat track, makes spiral arm be fixed in required deflection angle by the beat adjustment.
The lock handle of this light fixture spiral arm beat control device, can be one with the solid knob of the mutual spiral shell of spiral arm or one and the pull handle of spiral arm elasticity packing, fix in order to the mutual packing in relative position with the beat track.
The support arm of this light fixture spiral arm beat control device, its second end is pivoted into a rotating fulcrum mutually with first end of spiral arm, and the pivoting part interdigit is folded with a compression spring relatively, makes this rotating fulcrum be formed with the rotational pressure of a pre-sizing.
The beat track of this light fixture spiral arm beat control device is with to form between support arm is relative at 2 fixing.
The beat track of this light fixture spiral arm beat control device is fixing with between support arm is relative 2, can be formed by a bolt and a latching respectively.
Adopted the utility model light fixture spiral arm beat control device, can be by beat track between support arm and spiral arm and lock handle design, provide spiral arm a both stable and firm supporting construction, make the spiral arm can be for a long time and stably remain on arbitrary adjusted deflection angle, so can allow lamp body that the most appropriate good illumination effect is provided on stable angle and position, after using a period of time, known spiral arm is not easy to generate the shortcoming of becoming flexible beat and do not have, whole simultaneously adjustment is simple and easy fast, also meets human oriented design.
