Section through hole 122 connects, and then blocks closeouts in one end of the remote circuit board 50 of regulation through hole 122.
Because keeper 400 is made of elastomeric material, keeper 400 has certain deformability, control line with
When alternating current input line is located in threading hole 410 respectively, keeper 400 deforms upon, by control line and alternating current input line
It is clamped in keeper 400, the position of control line and alternating current input line is not easy to change, and is not easy to knot during use or twines
Around easy for installation, subsequent maintenance and convenient disassembly.Closeouts 30 are blocked in regulation through hole 122, the closure part 32 of closeouts 30
In regulation through hole 122, limiting section capping main regulation through hole 122, the contact surface of limiting section and blind end 12 is combined closely.By
It is rubber stopper in closeouts 30, the outer peripheral face of closure part 32 has multiple ring-type closure projections, and multiple ring-types block raised structure
Into overall structure be in installation base shape, positioned at the end of the remote limiting section of closure part 32 ring-type closure projection diameter most
It is small, it is inserted into from the end in regulation through hole 122, insertion is convenient, and as the depth down that closure part 32 is inserted, ring-type closure are convex
The contact risen with surrounding the inwall for adjusting through hole 122 is even closer, and dustproof and waterproof effect is good.
During driving power use, it is necessary to when adjusting the brightness of lamp body, using instruments such as screwdrivers from positioned at blind end
Inserted in regulation through hole 122 on 12, then the end of screwdriver directly contacts the electric adjustment portion on control panel, by turning
Dynamic screwdriver can realize the regulation to current strength, and then realize the regulation to lamp body brightness.Obviously, need not be adjusted usually
When saving brightness, blocked using closeouts 30 by through hole 122 is adjusted, do not tend to have water and dust enters, be hardly damaged the members such as control panel
Device, service life length.When needing regulation, closeouts 30 are extracted out of regulation through hole 122, it is easy to operate.
When needing to use hook 300, the connecting portion 320 for linking up with 300 is inserted into locating slot 161, then in screwed hole
Inside be spirally connected lock-screw, screws lock-screw so that the end of lock-screw is inserted into buckling groove, and can be pushed against connection
In portion 320, the connection of hook 300 is realized, hook 300 is suspended on into correct position realizes the installation of driving power, grasps
Make convenient and swift.
Preferred embodiment of the present utility model is the foregoing is only, is not limited to the utility model, for this
For the technical staff in field, the utility model can have various modifications and variations.It is all in the spirit and principles of the utility model
Within, any modification, equivalent substitution and improvements made etc., it should be included within the scope of protection of the utility model.
