Description

Collapsible desk lamp

Technical field

The present invention relates to a kind of collapsible desk lamp, the rotation through each member had both protected the lamp holder device to be difficult for collsion damage with folding, realized the stretching, extension and the contraction of Table lamp structure again, realized the utility function that the small size of product is taken in and launched.

Background technology

On the present market, in order to satisfy people's routine work living needs, the desk lamp of shape form formula emerges in an endless stream; But because volume problem; Bring inconvenience to transportation, and the desk lamp lamp holder very easily damages, ordinary incandescent lamp, the cracked generation fragment of electricity-saving lamp are big potential safety hazards.In recent years, along with semiconductor lighting infiltrates the life each side, the desk lamp design diversification that more becomes, it is inevitable to make that the small and exquisite folding desk lamp flexible, portable, easy to operate, that good looking appearance is generous of development becomes.

Summary of the invention

The objective of the invention is to the defective that exists to prior art, a kind of collapsible desk lamp is provided,, realize the folding of desk lamp and stretch, be easy to carry and operate through rotation to 4 parts of desk lamp.

Collapsible, collapsible desk lamp is as the form of desk lamp design, has been applied in the desk lamp design and receives liking of user, and the brief folding desk lamp of design forms a kind of fashion trend gradually on the current market.

For realizing above-mentioned purpose, design of the present invention is: the present invention realizes that through the rotating shaft of lamp holder and upper bracket plate lamp holder and the folding of upper bracket plate close up, and when folding, the lamp holder device is protected; Realize the rotation convergent-divergent of supporting plate up and down through the rotating shaft between upper bracket plate and the lower carriage plate; The support that rotating shaft through lower carriage plate and base realizes base with pack up.In use, desk lamp is used in the illumination that is launched into enough height; When taking in, be folded into the mobile phone size, both protected the lamp holder device to be difficult for collsion damage, small and exquisite again being easy to carry.

According to the foregoing invention design, the present invention adopts following technical proposals:

A kind of collapsible desk lamp comprises a lamp holder, is installed in the LED device on the lamp holder, a base, and two supporting plates connect the rotating shaft between lamp holder and upper bracket plate, upper bracket plate and lower carriage plate, lower carriage plate and the base, it is characterized in that:

A. between said lamp holder and the upper bracket plate, between upper bracket plate and the lower carriage plate, rely on rotating shaft to be rotationally connected between lower carriage plate and the base;

B. on the said lamp holder LED device is installed, realizes any rotation of lamp holder in predetermined angular by the rotation that is rotationally connected between lamp holder and the upper bracket plate;

C. between said upper bracket plate and the lower carriage plate, a positioner is arranged, guarantee can not unconfinedly to rotate between upper bracket plate and the lower carriage plate, electric wire is got worse when preventing the desk lamp cabling;

D. said base and lower carriage plate are chimeric, and when promptly amounting to, base embeds in the groove of lower carriage plate, and base one end half-circle-arc shape helps itself and the separating of lower carriage plate; The be rotationally connected bottom surface of face and base at place of the base other end and lower carriage plate maintains an equal level, and makes base and lower carriage plate perpendicular during expansion, prevents the desk lamp inclination.

Between said lamp holder and the upper bracket plate, the lower carriage plate is identical with pivot structure between the base: rotating shaft is to spin into complete rotating shaft by two the screwed connectors in two ends with the middle hole axle that has internal thread; The hole axle is wrapped with damped ring, with the fixing angle position that is turned over; Rotating shaft and supporting plate parallel, and supporting plate and lamp holder and base realize that open-close type is folding.

Said upper bracket plate be with the lower carriage plate between pivot structure: rotating shaft is to spin into complete rotating shaft by screwed connector with the connector that has internal thread; Respectively there is a damped ring at the rotating shaft two ends; With the fixing angle position that is turned over, play stable maintaining body state.Rotating shaft and two stands plate are perpendicular; Realize that the said positioner of two stands plate opposite planar rotation convergent-divergent is the part on upper bracket plate and the lower carriage plate up and down; The upper bracket plate is one of bore edges protrusion, and the lower carriage plate also protrudes one at bore edges, makes up and down supporting plate interference and can not turn over 360 ° when rotating; Guarantee can not unconfinedly to rotate between upper bracket plate and the lower carriage plate, electric wire is got worse when preventing the desk lamp cabling.

Above-mentioned collapsible desk lamp, its base length is half the greater than lamp holder length, in use unlikelyly topples over to guarantee it.

The present invention has following conspicuous outstanding substantive distinguishing features and remarkable advantage compared with prior art:

1. collapsible desk lamp of the present invention, moulding is brief, and collapsible becomes the mobile phone size, has both protected desk lamp lamp holder device, is easy to carry again.

2. collapsible desk lamp of the present invention, simple and reliable for structure, be convenient to user's operation.
