Further, described rotating shaft and locking plate are all articulated in base plate front, and described adjustment sheet is articulated in the base plate back side, and the locking plate back side is provided with the alignment pin that runs through base plate, and described elastic component one end connects this alignment pin, and the other end connects adjustment sheet bottom; Locking plate bottom is provided with the butt hook that runs through base plate, and the top of this butt hook and adjustment sheet is hinged.
Further, the alignment pin of the corresponding locking plate of described base plate is provided with cotter way, and the butt hook of the corresponding locking plate of base plate is provided with hook groove.
Further, the length of described cotter way is greater than the length of hook groove.
Further, described locking plate top is provided with stop tab away from a side of rotating shaft.
As mentioned above, the utility model arranges a locking system on rotating shaft side, and in the time that described projection is fastened in draw-in groove, rotating shaft can not be rotated, and can guarantee that lamp position is stable, is beneficial to the transport of light fixture; In the time that described projection exits draw-in groove, light fixture is removed locking, thereby can normally work.
Brief description of the drawings
Fig. 1 is the view of the utility model light fixture locking structure unlocked position;
Fig. 2 is the view of the utility model light fixture locking structure lock position.
Wherein: 10, base plate; 11, hook groove; 12, cotter way; 20, rotating shaft; 21, draw-in groove; 31, locking plate; 311, butt hook; 312, alignment pin; 313, projection; 314, stop tab; 32, adjustment sheet; 33, spring.
Detailed description of the invention
Below, by reference to the accompanying drawings and detailed description of the invention, the utility model is described further:
Refer to Fig. 1 and Fig. 2, the utility model has disclosed a kind of light fixture locking structure, comprises base plate 10, is articulated in the rotating shaft 20 on base plate 10 and is installed in the other locking system of rotating shaft 20, and this rotating shaft 20 is for fixedly mounting light fixture (not shown).
Described locking system comprises locking plate 31, elastic component and adjustment sheet 32, this locking plate 31 and adjustment sheet 32 are all articulated on base plate 10, specifically in the present embodiment, described locking plate 31 and rotating shaft 20 are all articulated in base plate 10 fronts, described adjustment sheet 32 is articulated in base plate 10 back sides, and the top of the bottom of locking plate 31 and adjustment sheet 32 is hinged, specifically, the bottom of locking plate 31 is provided with the butt hook 311 that runs through base plate 10, and this butt hook 311 is hinged at the back side of base plate 10 and the top of adjustment sheet 32; Described elastic component is a spring 33 in this enforcement, this spring 33 is connected between locking plate 31 tops and adjustment sheet 32 bottoms, specifically, the back side of described locking plate 31 is provided with the alignment pin 312 that runs through base plate 10, described spring 33 one end are connected in this alignment pin 312, and the other end is connected in adjustment sheet 32 bottoms; In order to vacate activity space to described alignment pin 312 and butt hook 311, described base plate 10 to should alignment pin 312 and butt hook 311 places offer respectively a cotter way 12 and a hook groove 11; Due in the present embodiment, the length of described locking plate 31 is greater than the length of adjustment sheet 32, and therefore, the length of this cotter way 12 is greater than the length of hook groove 11.
In described rotating shaft 20 outer peripheral sidewall, offer at least one draw-in groove 21, described locking plate 31 tops are provided with the projection 313 matching with draw-in groove 21 near a side of rotating shaft 20, concrete, this projection 313 is outwardly the extending to form of lateral edges by locking plate 31, the outer peripheral sidewall of described rotating shaft 20 offers spaced multiple draw-in groove 21, rotate locking plate 31, can make this locking system be fastened between the unlocked position that lock position in draw-in groove 21 and projection 313 depart from draw-in groove 21 and to move at described projection 313.
At locking system in lock position or while being in the unlocked position, the bottom of described adjustment sheet 32 rotates respectively to least significant and leftmost position, the elastic potential energy minimum now storing on spring 33, therefore this lock position and unlocked position are mechanical balance positions, and locking system to be adjusted to unlocked position (or conversely) from lock position, the artificially application of force, making spring 33 overcome the sub-equilbrium position of a mechanics (is that locking plate 31 and adjustment sheet 32 are positioned at the position on straight line, now, spring 33 has the longest elongation) could realize, this adjustment sheet 32 just for strengthen locking system on two positions time state stability arrange.
As further improvement, described locking plate 31 tops are provided with stop tab 314 away from a side of rotating shaft 20, this stop tab 314 be outwardly by the edge of locking plate 31, downwards (towards base plate 10) bending extends to form again, it is for limiting the angle of locking plate 31 toward rotating shaft 20 direction rotations, meanwhile, this stop tab 314 can also be as stirring the impetus that locking plate 31 rotates.
In sum, the utility model arranges a locking system on rotating shaft 20 sides, and when described projection 313 is fastened in draw-in groove 21 when interior, rotating shaft 20 can not be rotated, and can guarantee that lamp position is stable, is beneficial to the transport of light fixture; In the time that described projection 313 exits draw-in groove 21, light fixture is removed locking, thereby can normally work.
To one skilled in the art, can be according to technical scheme described above and design, make other various corresponding changes and deformation, and within these all changes and deformation all should belong to the protection domain of the utility model claim.
