CN86200372U - All direction desk lamp with auto-switch - Google Patents

Abstract

The utility model relates to a lighting desk lamp. The utility model combines a general mechanism which can arbitrarily turn in any direction with a retractable draw rod, and thus, the lighting direction and lighting scope of the desk lamp can be arbitrarily adjusted according to need. At the same time, due to the adoption of a specially designed automatic switch, the switch is not specially shifted, and the self-closing of power supply can be realized.

Description

All direction desk lamp with auto-switch

The invention belongs to a kind of improved desk lamp.

General desk lamp mainly is made up of lamp socket, pole, switch, bulb, power line.The desk lamp pole that has can turn to arbitrary orientation, thereby regulates the field of illumination, but because strut lengths is fixed, so illumination zone is still less, is positioned on the fixed position owing to switch in addition, so in order to open and close desk lamp, need press the switch of fixed position.

The objective of the invention is existing desk lamp is improved,, need not press any switch specially simultaneously, can realize the automatic shutter of power supply, bring convenience to the user to realize to carry out adjusting in a big way to field of illumination, illumination orientations.

Below in conjunction with accompanying drawing its structure is described further.

Fig. 1 is a structural representation of the present invention.

Fig. 2 is the mercury automatic switch structural representation among the present invention.

(1) is lamp socket among the figure, (3) be mounted in mercury automatic switch on the pull bar (4), (5) be bulb, (6) be power line, (4) be pull bar, its length can be stretched, the bar intermediate hollow, can pass power line, (2) be omnidirectional mechanism, can turn round as required to various directions, pull bar (4) and omnidirectional mechanism (2) are formed pole, and whole pole both can be stretched, can turn round again to various directions, (7) be the end cap made from insulating materials, (8) are protective liquid (as the transformer wet goods), are used for preventing to connect power supply suddenly and cause spark phenomenon, (9) be mercury bead, (10) be bottom electrode, it and mercury bead always keep in touch state, and (11) are electrode cables, (12) be the housing that insulating materials is made, (13) be segment shape top electrode, when pole was near vertical direction, mercury bead only contacted with bottom electrode, and the disengaging top electrode, this moment, circuit disconnected, and bulb does not work, and when the pole arbitrary orientation departs from vertical direction, mercury bead not only still contacts with bottom electrode, and contact with top electrode, thereby making circuit turn-on, bulb is given out light.Here indication near vertical direction or depart from the degree of vertical direction, determine by the concrete manufacturing dimension of mercoid switch.

During use, Zhao Ming scope as required, regulate direction and telescopic lever adjustable range with omnidirectional mechanism, lamp is pulled on one side own, bulb is given out light at once automatically, and when stopping using, as long as pull bar is back into normal position (being that pull bar is near vertical direction), circuit is automatic disconnection, and bulb extinguishes.

Claims (1)

1, a kind of lighting lamp of forming by lamp socket [1], pole, switch [3], bulb [5], power line [6]; it is characterized in that said pole by telescopic pull bar [4] and arbitrarily the omnidirectional mechanism of rotation direction [2] constitute; switch is made of insulated end cover [7], protectiveness liquid [8], mercury bead [9], bottom electrode [10], lead [11], segment shape top electrode [13], insulation shell [12], and switch [3] is installed on the pull bar [4].
