The syndeton of a kind of track lamp lamp tube and lamp cover
Technical field
The utility model relates to a kind of syndeton of lamp tube and lamp cover of track lamp.
Background technology
The structure of existing track lamp is varied, generally include the linking arm that is used to connect track and light fixture, light fixture comprises the lamp tube, lamp tube front end is provided with the lamp cover, the general employing is threaded or the screw locking between the lamp tube of present track lamp and the lamp cover, above-mentioned two kinds of structures all need the lamp cover is pulled down when installation and maintenance or replacing fluorescent tube, dismounting back light cover is lost easily, particularly when adopting the screw locking, not only the lamp cover is lost easily, and for this finding of screw, easier loss is given to install once more and is come very big inconvenience again.In addition, the feasible cover that turns on the light of above-mentioned two kinds of structures bothers very much, wastes time and energy.
The utility model content
Technical problem to be solved in the utility model is to overcome the deficiency of above-mentioned prior art, need not pull down turning on and the lamp tube of all quick, easy, the time saving and energy saving track lamp of clamping and the syndeton of lamp cover of lamp cover, lamp cover when a kind of simple in structure, installation and maintenance being provided or changing fluorescent tube
The lamp tube of a kind of track lamp that provides according to the utility model and the syndeton of lamp cover comprise lamp tube and the lamp cover that covers with lamp tube front end, between described lamp tube and the lamp cover side flexibly connect, the opposite side clamping.
The utility model also has following attached technical characterictic:
One side of described lamp cover is stretched out a tongue piece, this tongue piece is hinged by a described side of rotating shaft and lamp tube, the opposite side of described lamp cover is provided with an activity template, this activity template middle part is hinged by another rotating shaft and lamp cover opposite side, this inboard, activity template upper end is provided with a grab, this grab is connected in the draw-in groove that is formed in lamp tube opposite side, is provided with the compression spring between the opposite side of inboard, described activity template lower end and lamp cover.
The lamp tube of a kind of track lamp that provides according to the utility model and the syndeton of lamp cover compared with prior art have following advantage: between described lamp tube and the lamp cover side flexibly connect, the opposite side clamping, when making installation and maintenance or replacing fluorescent tube, this structure need not pull down the lamp cover, opening with clamping of lamp cover is all quick, easy, time saving and energy saving, and simple in structure.
Description of drawings
Fig. 1 is a kind of structural representation of optimal way of the syndeton of the lamp tube of a kind of track lamp of the utility model and lamp cover.
The specific embodiment
Referring to Fig. 1, a kind of optimal way of the syndeton of the lamp tube of a kind of track lamp of the present utility model and lamp cover is shown, comprise lamp tube 1 and the lamp cover 2 that covers with lamp tube front end, a side flexibly connects between described lamp tube and the lamp cover, the opposite side clamping, one side of described lamp cover is stretched out a tongue piece 10, this tongue piece is hinged with a described side of lamp tube by rotating shaft 11, the opposite side of described lamp cover is provided with an activity template 12, this activity template middle part is hinged with lamp cover opposite side by another rotating shaft 16, this inboard, activity template 12 upper end is provided with a grab 13, this grab is connected in the draw-in groove 14 that is formed in lamp tube opposite side, is provided with compression spring 15 between the opposite side of inboard, described activity template 12 lower ends and lamp cover.
In use, when lamp tube and lamp cover are covered, pin the lower end of activity template 12,15 compressions of compression spring, activity template is rotated counterclockwise around another rotating shaft 16, activity template upper end perk is stretched into the grab 13 on the activity template in the draw-in groove 14, unclamps activity template 12, at this moment, compression spring 15 recovers strain and tightly withstands inboard, activity template lower end, makes the grab 13 of activity template upper end tightly be connected in the draw-in groove 14, thereby realizes covering of lamp tube and lamp cover.When turning on the light cover, only need press the activity template lower end, making grab 13 break away from draw-in groove 14 gets final product, therefore the lamp cover open with clamping all quick, easy, time saving and energy saving, and need not pull down the lamp cover when installation and maintenance or replacing fluorescent tube, only need be opened the joint end of lamp cover and lamp tube and get final product, and it is simple in structure in addition.
