Abstract
The invention belongs to lighting device technical field, and in particular to a kind of lighting device with left-hand thread compressing structure.Including skull, stack shell and lamp bracket, stack shell one end is provided with the opposite internal thread and external screw thread in direction of rotation, and skull is connected with stack shell by external screw thread, and lamp bracket is connected with stack shell by internal thread.After stack shell is threadedly coupled with skull, lamp bracket with the screw thread of skull screw thread opposite direction with stack shell internal thread from being connected, and lamp bracket boss face contacts spacing compression skull with skull boss face, and now skull and stack shell are non-dismountable.Lamp bracket need to be dismantled to the threaded connection of rear removable head cover and stack shell.It can prevent user from tearing the problem of and can dismantles lighting device by other means open by mistake using middle so as to reach, dismounting process is simple.
Description
Technical field
The invention belongs to lighting device technical field, and in particular to a kind of lighting device with left-hand thread compressing structure.
Background technology
Existing lighting device is mostly multistage split-type structural, i.e. skull 3, stack shell 1, tail-hood etc..Spiral shell is used between each part
Line is connected, to prevent skull 3 is connected to back-out by user using maloperation during lighting device with stack shell 1 from influenceing normally to make
With frequently with screw thread gluing knot.The problems such as adhesive structure presence can not repair, defective products is high, tedious process.
The content of the invention
It is an object of the invention to provide a kind of lighting device with left-hand thread compressing structure, solves existing illumination dress
Being set to prevents user from tearing a series of problems existing for gluing bonding open by mistake.
The technical solution of the present invention is to provide a kind of lighting device with left-hand thread compressing structure, including skull 3,
Stack shell 1 and lamp bracket 2, it is characterized in that：Above-mentioned one end of stack shell 1 is provided with the opposite internal thread and external screw thread in direction of rotation, on
State skull 3 to be connected by external screw thread with stack shell 1, above-mentioned lamp bracket 2 is connected with stack shell 1 by internal thread.
Preferably, above-mentioned one end of lamp bracket 2 is provided with first annular boss 4, and the inwall of skull 3 is provided with the second annular boss 5, right overhead
After lid 3 screws in stack shell 1 with lamp bracket 2, first annular boss 4 contacts with the second annular boss 5, spacing compression skull 3；Definition,
The first annular annular boss 5 of boss 4 and second is medial surface close to the face of stack shell 1.
Preferably, the face of stack shell 1 and the end contact of skull 3 is step surface, after skull 3 screws in stack shell 1, the end face of skull 3
Spacing tighten is contacted with the step surface 11 of stack shell 1.
Preferably, above-mentioned external screw thread is left hand thread, and above-mentioned internal thread is right-handed thread；Or above-mentioned external screw thread is dextrorotation spiral shell
Line, above-mentioned internal thread are left hand thread.
The beneficial effects of the invention are as follows：
After stack shell is threadedly coupled with skull, lamp bracket is selected to be connected with the screw thread of skull screw thread opposite direction and stack shell internal thread
Connect, lamp bracket boss face contacts spacing compression skull with skull boss face, and now skull and stack shell are non-dismountable.Lamp bracket need to be dismantled
The threaded connection of rear removable head cover and stack shell.It can prevent user from tearing and can open by mistake by other means using middle so as to reach
The problem of dismantling lighting device, dismounting process are simple.
Brief description of the drawings
Fig. 1 is the sectional view of lighting device of the present invention；
Reference is in figure：1- stack shells, 11- step surfaces, 2- lamp brackets, 3- skulls, the first annular boss of 4-, the rings of 5- second
Shape boss；
Embodiment
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.
Such as Fig. 1, the present invention includes stack shell 1, lamp bracket 2 and skull 3, one end inside and outside wall of stack shell 1 and is respectively arranged with direction of rotation
Opposite internal thread and external screw thread, after skull 3 is threadedly coupled with the external screw thread of stack shell 1, lamp bracket 2 is from opposite with the screw thread of skull 3
The screw thread in direction is connected with the internal thread of stack shell 1；The one end of lamp bracket 2 is provided with first annular boss 4, and the inwall of skull 3 is provided with the second ring
Shape boss 5, when skull 3 and lamp bracket 2 screw in stack shell 1, the medial surface of first annular boss 4 and the second annular boss 5 outside
(it is medial surface to define the first annular annular boss 5 of boss 4 and second close to the side of stack shell 1 to contacts side surfaces, otherwise is outside
Face), spacing compression skull 3；Now skull 3 and stack shell 1 are non-dismountable.Lamp bracket 2 need to be dismantled rear removable head cover 3 and stack shell
1 threaded connection.
The present invention operation principle be：When skull 3 is threadedly coupled with stack shell 1, the right side of skull 3 contacts with stack shell step surface 11
It is spacing to tighten.After loading lamp bracket 2, the first annular boss face of lamp bracket 2 and the second spacing compression of convex annular deck contact of skull 3
Skull 3, lamp bracket screw thread and skull hand of spiral on the contrary, now skull 3 and stack shell 1 due to the reverse thread of lamp bracket 2 compresses can not
Dismounting.Lamp bracket 2 need to be dismantled to the threaded connection of rear removable head cover 3 and stack shell 1.It can be prevented in user's use so as to reach
Tear the problem of and can dismantles lighting device by other means open by mistake.
