Abstract

The utility model discloses a lamp appliance which comprises a base, a rotatable lamp arm which is formed by that a lower prop is connected with an upper prop by a pin, and a lamp head which is used for assembling and fixing a bulb. The utility model is characterized in that the outer side of the lamp head is provided with an adiabatic cover body, the pipe arms of the end surfaces of the front and the back connecting heads of the upper prop are convexly provided with inserting pipes, and the inserting grooves of the upper prop are respectively inserted into the inserting pipes. The utility model with the structure can strengthen and isolate heat source generated from the lamp head and adopt the connection mode of the inserting grooves and the inserting tenons to further strengthen the bond strength of the props, improving the using safety and the endurance of a working lamp.

Description

A kind of light fixture

The utility model relates to a kind of light fixture.

Existing portable lamp be with the high Halogen lamp LED of illuminance as the luminous lighting source, its design feature is: have the arm that is pivoted with rotatable multisection type on the base of fixation, the upper end of this arm is assembled with bulb and has the lamp holder of pull handle.And above-mentioned multisection type arm is to be articulated by upper supporting column and lower supporting rod to constitute, and making this portable lamp can be the crooked easily rotation of axle with the pivoting point.During use, the pull handle on the pulling lamp holder can drive the multisection type arm, need the illumination part thereby illuminating lamp holder is moved to.The housing of above-mentioned lamp holder is made with metal material, the high temperature that bulb is given out in the time of can bearing illumination.Yet with Halogen lamp LED is that the temperature that in use given out of illuminating portable lamp is quite high, and the housing of lamp holder is often made with the high aluminum metal of the coefficient of heat conduction, does not need the time for a long time, and the lamp holder that metal is made will be hot.And the user is because of the needs of illumination, must usually adjust the angle of illumination, normal because of wholwe-hearted work so that do not lift and to stretch out one's hand the pull handle that just removes to draw lamp holder, this accidentally will touch lamp holder in a flash, and the high temperature on the lamp holder very easily handle scald, so that the portable lamp of this structure uses is quite dangerous.On the other hand, must often adjust during owing to work and throw light on, so need the pulling pull handle that lamp holder is placed the appropriate location, the multisection type arm of being engaged in this traction work just must bear external active force.And the upper supporting column of work on hand lamp multisection type arm comprises the forward and backward joint that sectional area equates, and forward and backward termination forms simple square shape sleeve pipe respectively, the simple solid flange sleeve of end, upper supporting column two ends can be closed to be assembled into one.This mode that is assembled, because the rubbing surface that bead only forms less area with some small sizes on every side and sleeve pipe wall, so the frictional force deficiency, fastness is bad, is easy to will make it to come off under the situation of often pulling.In addition, this square shape sleeve pipe only entangles the bead at upper supporting column two ends with inner wall surface thereof, and the internal face of sleeve pipe is not thick, intensity is limited, lamp holder has constant weight again in addition, therefore when torsional moment is born in the suit place, uses through a period of time, bead that the square shape sleeve pipe very easily is inserted in it struts, even breaks and can't re-use.

The purpose of this utility model is a kind of light fixture of design, and this light fixture is safe and reliable, and intensity is good, solid, durable.

Order of the present utility model is realized by following scheme:

This light fixture has base, the multisection type arm, the lamp holder of bulb can be installed, wherein base is provided with pin joint seat, this pin joint seat connects the multisection type arm, the multisection type arm is made of lower supporting rod bolt upper supporting column, before the upper supporting column two ends connect respectively, back joint, before, back joint is connected with lower supporting rod and lamp holder respectively, it is characterized in that: be arranged with in the lamp holder outside one can be heat insulation cover body, face is provided with dovetail groove and recess around the lamp holder, and the shank inner edge on the cover body is provided with dovetail, and cover body inside is provided with protuberance, when cover body and lamp sleeve fashionable, described protuberance and recess are chimeric mutually, and dovetail groove and dovetail are chimeric mutually; Be equipped with intubate on the end face tube wall of joint before and after the described in addition upper supporting column, insert upper supporting column front and back slot in the intubate.

This light fixture has the following advantages:

1, security is good, can avoid high temperature to scald: because the cover body of lamp holder arranged outside is made by heat-barrier material, so the high temperature that is sent by Halogen lamp LED can be isolated by this cover body, thereby avoided the scald that causes because of touching accidentally during use.In addition owing to after having added cover body on the portable lamp, can make the moulding of this lamp more attractive in appearance.

2, structural strength height, can increase durability: because the end face tube wall of the forward and backward joint of described upper supporting column is equipped with the grafting tenon, thereby form the form of two-sided clamping, not only improved structural strength, and frictional force also strengthens relatively, therefore can bear bigger torsional moment and can not damage.
