Description

Lamp support
Technical field
The invention belongs to the technical fields of lamp mounting rack, are to be related to a kind of lamp support more specifically.
Background technique
The installation of lamp body (such as LED light/fluorescent lamp) is very universal in modern production life, is currently used for installation lamp body Lamp support be usually to weld/be molded into integral piece, lamp body is fixed on lamp support, and lamp support is fixed in ceiling/equipment. Perhaps all in the case of lamp support volume size it is larger, cause lamp support carry/it is difficult to install.
Summary of the invention
The purpose of the present invention is to provide a kind of lamp supports, tired to solve lamp holder carrying/installation existing in the prior art Difficult technical problem.
To achieve the above object, the technical solution adopted by the present invention is that: providing a kind of lamp support includes first crossbeam, second Crossbeam, the first stringer and the second stringer;First stringer and second stringer are located at the first crossbeam and institute It states between second cross beam;One end of first stringer is detachably fixed with the first crossbeam to be connect, first stringer The other end is detachably fixed with the second cross beam and connect;One end of second stringer is detachably fixed with the first crossbeam Connection, the other end of second stringer is detachably fixed with the second cross beam to be connect;The first crossbeam and described first The intersection of stringer is provided with the first hanging beam, the bottom end of first hanging beam respectively with the first crossbeam and first stringer It is detachably fixed connection;The intersection of the first crossbeam and second stringer is provided with the second hanging beam, second hanging beam Bottom end be detachably fixed and connect with the first crossbeam and second stringer respectively;The second cross beam and described first is indulged The intersection of beam is provided with third hanging beam, and the bottom end of the third hanging beam respectively can with the second cross beam and first stringer Disassembly is fixedly connected;The intersection of the second cross beam and second stringer is provided with the 4th hanging beam, the 4th hanging beam Bottom end is detachably fixed and connect with the second cross beam and second stringer respectively.
Further, connection is detachably fixed by rivet nut between the first crossbeam and first stringer, and/ Or connection is detachably fixed by rivet nut between the first crossbeam and second stringer.
Further, connection is detachably fixed by rivet nut between the second cross beam and first stringer, and/ Or connection is detachably fixed by rivet nut between the second cross beam and second stringer.
Further, first hanging beam, second hanging beam, the third hanging beam and the 4th hanging beam difference Extend along the vertical direction.
Further, the first crossbeam, the second cross beam, first stringer, second stringer, described first Hanging beam, second hanging beam, the cross section difference of the third hanging beam and the 4th hanging beam are L-shaped.
Further, the first strip-shaped hole passed through for lamp mounting screw is provided on the first crossbeam, described second is horizontal The second strip-shaped hole passed through for lamp mounting screw is provided on beam.
Further, the quantity of first strip-shaped hole is multiple, multiple first strip-shaped hole prolonging along pre- boning out Stretch direction arrangement.
Further, it is equidistantly arranged between multiple first strip-shaped holes.
Further, the quantity of second strip-shaped hole is multiple, and multiple second strip-shaped holes are along the pre- boning out Extending direction arrangement.
Further, it is equidistantly arranged between multiple second strip-shaped holes.
The beneficial effect of lamp support provided by the invention is: compared with prior art, lamp support provided by the invention, the One crossbeam, second cross beam, the first stringer, the second stringer, the first hanging beam, the second hanging beam, third hanging beam and the 4th hanging beam are mutual Between be detachably fixed, installation when, can assemble respectively, very convenient;Lamp support passes through the top of the first hanging beam, the The top on the top of two hanging beams, the top of third hanging beam and the 4th hanging beam, which is hung, to be set on the ceiling, and four hanging beams have shared lamp The weight of bracket mounts and dismounts also very convenient;First crossbeam, the first stringer, second cross beam and the second stringer are successively mutually solid Fixed, gravity is mutually shared, and the stability of lamp support is improved;First crossbeam, the first stringer, second cross beam and the second stringer are mutual Fixed to restrain, there are two fixed points for each component, will not directly fall, be promoted a fixed point occurs and loosens The stability and safety of lamp support.
When this patent is aboard ship installed, in advance by stud welding on the mounting surface of body section, then body section into It goes the paint construction stage, after paint application, is welded on hull stud in advance this patent lamp support to be installed to.It is such Advantage is: previous way: lamp bracket is welded on hull, increases sanding and paint difficulty, and dead angle is easily reduced paint attachment Power directly affects paint quality, and transportational process, which will cause, hits curved lamp support and reprocess, and there is also modification after the completion of oil paint coating The problems such as lamp support etc..This patent does not need to be welded after hull paint application, can directly pass through bolt and weldering in advance The stud fastening connect, greatly reduces the work for burning out paint and repairing paint.
