The technical solution of the utility model is further described below:
Described lamp socket comprises drain pan and is located at the lid on drain pan, is at least provided with the pivot joint ear that pair of parallel arranges on described drain pan; Described pivotal axis is provided with the ear chamber of matching with pivot joint ear, embed for pivot joint ear, and described pivot joint ear outer wall and ear chamber interior walls are close to produce the frictional force of enough brakings; Pivotal axis is separated into some auricles by described ear chamber, has the axis hole of coaxial line on each auricle.
Such scheme changes the structure of traditional single pivot joint face, utilize ear chamber interior walls to clamp described pivot joint ear from two sides, frictional force can be effectively provided, pin-jointed structure is more surely leaned on, can facilitate again workman to be alignd in drive-connecting shaft and pivot joint ear location, avoid the situation that while installation in traditional scheme, pivot joint ear and drive-connecting shaft easily misplace.
Further, between described ear chamber interior walls and pivot joint ear, be provided with the first pad for increasing friction force.
Further, between described ear chamber interior walls and pivot joint ear, be provided with the second pad for eliminating the noise, avoid pivot joint ear outer wall directly to rub and send noise with ear chamber interior walls.
Further, described pivotal axis one end is laterally extending to be had for the accommodating holding part of nut, and described holding part and pivoted hole connect, and its section configuration conforms to limit nut rotation with nut.
Further, described holding part is provided with one or more breach, for nut being pressed to screw rod in the time that screw rod and nut screw.Use light instrument, by described holding part emargintion, nut is pressed to screw rod direction, can realize screwing fast of screw rod; Also can fail effectively to limit at nut undersized, holding part inwall and when it rotates, realize and the screwing of screw rod, this design permits meter nut outer profile size to have the difference of certain limit.
Further, described drive-connecting shaft is fixed by the sleeve supporting on lamp socket, and described axle sleeve comprises the lower camber side of being located at lamp socket drain pan and the upper cambered surface of being located at lamp socket lid.Because the supporting that has axle sleeve is fixed, pivot structure is more firm, and it is more steady rotating.
Further, described pivotal axis is connected with column, and described arm presents elongated tubular, and it is sheathed on described column.
Further, the clearance structure that offers the connecting portion activity between pivotal axis and column when the pivotable on described lamp socket.Establish and can be located in lamp socket by pivot part by clearance structure, both effectively utilized lamppost seat inner space, also can increase flexibility and the aesthetic feeling of Design of Luminaires.
Further, the rear end of lamp socket is located in the articulated section of described lamp socket and arm.According to actual design demand, lamp socket rear end, both sides or central authorities can be located in articulated section.
The utility model has the advantage of: solid and reliable, pivotal adjustment convenience, does not need to regulate with instrument in addition; When pivotable, can not send ear-piercing noise, promote user's experience and the class of product; The extension design of pivotal axis fully takes into account the simplification of assembling and the otherness of materials, and both having facilitated workman to complete fast light fixture has assembling, the nut within the scope of again can compatible certain size; Clearance structure designs flexibly, increases the aesthetic feeling of light fixture when effect is utilized lamppost seat inner space.In sum, no matter the utility model in technical or practicality, is all the products that possess superior function, has very high promotional value.

Detailed description of the invention
As follows by reference to the accompanying drawings, the application's scheme is further described:
A kind of desk lamp pin-jointed structure, this desk lamp comprises lampshade, arm 1 and lamp socket 2, described arm lower end is provided with pivotal axis 3, on this pivotal axis 3, has axis hole 31; Described lamp socket 2 is provided with the pivot joint ear 21 coordinating with described pivotal axis 3, and described pivotal axis 3 is locked by screw rod 4, nut 5 with pivot joint ear 21.
Described lamp socket 2 comprises drain pan 22 and is located at the lid 23 on drain pan 22, is at least provided with the pivot joint ear 21 that pair of parallel arranges on described drain pan 22; The ear chamber 32 that described pivotal axis 3 is provided with is that match with pivot joint ear 21, embed for pivot joint ear 21, described pivot joint ear 21 outer walls and ear chamber 32 inwalls are close to produce the frictional force of enough brakings; Pivotal axis is separated into some auricles 33 by described ear chamber 32, has the axis hole 31 of coaxial line on each auricle 33.
Such scheme changes the structure of traditional single pivot joint face, utilize ear chamber 32 inwalls to clamp described pivot joint ear 21 from two sides, frictional force can be effectively provided, pin-jointed structure is more surely leaned on, can facilitate again workman to be alignd in drive-connecting shaft 3 and pivot joint ear 21 location, pivot joint ear 21 and the easily situation of dislocation of drive-connecting shaft 3 while avoiding installing in traditional scheme.
