Abstract
The utility model relates to a device for regulating angle of desk lamp. A connector is fixedly arranged on a lamp casing. The bottom of the connector is provided with a ring body. The ring body can be contained inside a containing groove positioned on an upper pivoting block. A positioning plate is embedded into the containing groove of the upper pivoting block, and locked and positioned inside the containing groove by the connector. Meanwhile, the ring body of the connector can not be released from the containing groove as the ring body is appropriately pressed by the positioning plate but can still be left and right rotated under the action of force. By adopting that, besides the angle of the desk lamp can be regulated by the user, the lamp casing can be rotated with the direction of the force when one end of the lamp casing is collided by the external force, thereby preventing the damage of the desk lamp.
Description
Technical field
The utility model relates to a kind of angle adjustment structure of desk lamp, refers in particular to can make lamp housing do left and right orientation angle adjustment and have article to drop when bump above desk lamp, and lamp housing can be with being rotated by force direction, and prevent the adjustment structure of desk lamp damage.
Background technology
It has often been said that eyes are window of souls, so quite important for the sheet day health care of eyes.And with regard to daily eye health item except allowing the correct set that eyes have a rest, read a book, write in good time, whether also be considerable link for the abundance of light.Generally speaking, when workbench or desk are rather dark, can set up desk lamp at workbench or desk appropriate location usually, so that bright and clear, prevent the generation of eye fatigue and myopia.And general desk lamp is all only set up the pin-jointed structure of adjustable angle on support arm, for then adopting the mode that directly sets firmly between support arm and the lamp housing, yet adopt this kind design, if when any end at an external strength (dropping as article) bump lamp housing two ends was arranged, the lamp housing of military order desk lamp was damaged in the jackknifing of support arm junction.
Summary of the invention
Main purpose of the present utility model is the defective that overcomes above-mentioned prior art, and a kind of adjustment structure of desk lamp angle is provided, and except that the adjustable light source direction, if when an end of external force collision lamp housing is arranged, lamp housing can rotate with application of force direction, to prevent the desk lamp damage.
The purpose of this utility model is to adopt following technological means to realize: a kind of adjustment structure of desk lamp angle, group is established support arm on pedestal, support arm mat coupling assembling and lamp housing are pivoted, lamp housing is established for light tube group, it is characterized in that: the combination of coupling assembling and lamp housing is by the setting of last pivot joint block, connector and spacer, promptly go up the top of pivot joint block and establish a tank, screw is arranged in the tank; A ring body is established in the bottom of connector, and a combined segment is respectively extended in the both sides of ring body, respectively establishes a perforation at the cross bar two ends partly of combined segment, sets up combined segment in the rear side extension of ring body, and perforation is set on the combined segment, and spacer is provided with two perforation; During combination, the ring body and the spacer of connector are inserted in the tank of pivot joint block, pass perforation with fixture and be locked in the screw, with fixture wear the perforation of connector and be screwed into lamp housing screw hole column, will go up that pivot joint block, connector and lamp housing are affixed to be integral.
Be convexly equipped with block on the end limit of the spacer of the adjustment structure of described a kind of desk lamp angle, with two combined segment of retaining system connector.In order to increase the attractive in appearance of desk lamp, can establish a lid at the fixing position lock of connector and lamp housing, pass lid and be locked on the combined segment of connector with fixture.
Advantage of the present utility model is: can be owing to be provided with between support arm and the lamp housing for the pin-jointed structure of adjusting angle, and can make the angle adjustment of desk lamp light source more meet user's demand; Owing to be the pivot joint state between support arm and the lamp housing, when imposing on arbitrary end of lamp housing, lamp housing will rotate with application of force direction as external force (as the article bump) simultaneously, to prevent that desk lamp is from the fracture damage of the junction of lamp housing and support arm.

The specific embodiment
Below in conjunction with drawings and Examples structure of the present utility model is elaborated.
As Fig. 1, Fig. 2 and shown in Figure 3, the utility model is organized on pedestal 10 and is established support arm 20, and support arm 20 is pivoted by coupling assembling 30 and lamp housing 40, and lamp housing 40 is established for light tube group; The combination of coupling assembling 30 and lamp housing 40 is mainly by the setting of last pivot joint block 1, connector 2 and spacer 3, and top end of pivot joint block 1 is provided with a tank river 11 on this, and screw 12 is arranged in the tank 11; The bottom of connector 2 is provided with a ring body 21, respectively extend a combined segment 22 in the both sides of ring body 21, respectively there is a perforation 23,23 ' at cross bar place, two ends partly in combined segment 22, sets up combined segment 24 in the rear side extension of ring body 21, and perforation 25 is set on combined segment 24; Establish two perforation, 31, two perforation, 31 corresponding two screws 12 of going up pivot joint block 1 on spacer 3, be convexly equipped with a block 32 on the end limit of spacer 3, set up three screw hole columns 41 on lamp housing 10, screw hole column 41 is corresponding with the perforation 23,25 on the connector 2 respectively.
When the combination desk lamp, as shown in Figure 3, Figure 4, in regular turn in the tank 11 that the ring body 21 and the spacer 3 of connector 2 are inserted pivot joint block 1, and make the perforation 31 of two on the spacer 3 corresponding with two perforation 12 of last pivot joint block 11, passing perforation 31 with fixture 5 again is locked in the screw 1, connector 2 is located at for 1 group with last pivot joint block, make the perforation 23 at combined segment 22 rears of connector 2 and the screw hole column 41 on the 25 corresponding lamp housings 40 of the perforation on the combined segment 24, after wearing perforation 25, be screwed into screw hole column 41 with fixture 5 again, with connector 2 and lamp housing 40 affixed being integral; In order to increase the attractive in appearance of lamp housing 40, can establish a lid 42 at connector 2 and lamp housing 40 fixing positions lock.Pass lid 42 and another perforation 23 ' of being locked on the combined segment 22 of connector 2 is located with fixture 5.
Because fixture 5 is behind perforation 31 of passing spacer 3 and the screw 12 that is locked on pivot joint block 1, the ring body 21 of this connector 2 just is positioned sheet 3 with suitable urgent degree cramping, make it outside the location, still can rotate down stressed, be that the user can directly force in lamp housing 40, nationality lamp housing 40 sets firmly with connector 2, connector 2 is rotated to the left or to the right, adjust lamp housing 40 left and reach, angle to the right, and the adjusting range of its angle will be subjected to the restriction of block 32, mainly be because block 32 is convex shape, so when connector 2 rotates to the left or to the right, the right side of connector 2 or the combined segment in left side 22 will be subjected to the block of block 32, so the rotational angle that will limit lamp housing 40 is (as Fig. 5, shown in Figure 6).
