Abstract
A lamp rod comprises a retaining seat and an inserting rod. A wire connecting box has a via hole at a periphery thereof. A lateral side of the retaining seat extends with an inserting portion exactly passing through the via hole of the wire connecting box. A positioning ring is positioned at an interior of the wire connecting box for locking the inserting portion. One end of the retaining seat far away from the wire connecting box has two sliding grooves. One end of the inserting rod coupled to the retaining seat is installed with an inserting seat. Two sides of the inserting seat have stepped guide blocks. The guide blocks are exactly engaged with the two sliding grooves of the retaining seat. Thereby, in transfer and storage, the inserting rod can be pulled out from the wire connecting box so as to occupy a smaller space.
Description




FIELD OF THE INVENTION




The present invention relates to lamps, and particularly to an easily assembled lamp retaining device, wherein the inserting rod can be pulled out from a wire connecting box for transfer and storage by only using a smaller space. Furthermore, the user can assemble the inserting rod by just inserting the inserting rod into the wire connecting box.




BACKGROUND OF THE INVENTION




Prior wire connection devices of lamps, such as wall lamps, stand type lamps, and ceiling lamps, use studs and nuts to lock the components. In assembly, not only the user is easy to be harmed, but also other locking tools (such as spanners, openers, etc.) are necessary. Moreover, in assembly, electric wires are easy to expose out and some dangers are induced. Thereby, the prior art is not suitable to be assembled by the user himself (or herself). In general, since in the prior art design, the wire is possibly exposed out if the assembly work is performed by the user, the manufacturer assembles the device in advance, namely, the wire box is assembled with inserting rods in the manufacturing process. However, this will induce that a large space is required for transferring and storing and thus cost is increased.




SUMMARY OF THE INVENTION




Accordingly, the primary object of the present invention is to provide an easily assembled lamp retaining device comprising a retaining seat at a lateral side of a wire connecting box, and an inserting rod inserted into the retaining seat. The wire connecting box has a via hole at a periphery thereof. A lateral side of the retaining seat extends with an inserting portion exactly passing through the via hole of the wire connecting box. A positioning ring is positioned at an interior of the wire connecting box for locking a portion of the inserting portion. One end of the retaining seat far away from the wire connecting box has two sliding grooves. One end of the inserting rod coupled to the retaining seat is installed with an inserting seat. Two sides of the inserting seat have stepped guide blocks. The guide blocks are exactly engaged with the two sliding grooves of the retaining seat. Thereby, the inserting rod can be pulled out from the wire connecting box for transferring and storage with a smaller space.




Another object of the present invention is to provide an easily assembled lamp retaining device, wherein a limiting ring is released, then the inserting rod can be pulled out. Thus it can be packaged and stored, the wire connecting box and inserting rod can be detached so as to reduce the volume for storing, transferring and packaging. Since the wire connecting box and inserting rod can be detached for reducing the space in transferring and storing, and the retaining seat inserted by the inserting rod is installed to the wire connecting box in advance. Thereby, the user need only insert the inserting rod into the wire connecting box and then lock the limiting ring and thus the assembly of the present invention is completed. No other stud, or tool is necessary in the assembly process.











The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS




With reference to

FIGS. 1 and 3

, the structure of the easily assembled lamp retaining device according to the present invention is clearly illustrated. The present invention is formed by a retaining seat


1


at a lateral side of a wire connecting box D, and an inserting rod


2


inserting into the retaining seat


1


.




The wire connecting box D has a via hole D


1


at a periphery thereof, and each of two sides of the via hole D


1


has a respective buckling groove D


11


.




A lateral side of the retaining seat


1


extends with an inserting portion


11


exactly passing through the via hole D


1


of the wire connecting box D. The interior of the inserting portion


11


has a through hole


111


. Two sides of the inserting portion


11


corresponding to at two sides of the via hole D


1


have buckling protrusions


112


for positioning the retaining seat


1


. A positioning ring D


2


at an interior of the wire connecting box D serves to lock the inserting portion


11


. Thereby, the retaining seat


1


is positioned at an outer side of the wire connecting box D. One end of the retaining seat


1


far away from the wire connecting box D has two sliding grooves


12


. A buckling block


13


is positioned between the two sliding grooves


12


. An outer edge of the buckling block


13


is extended with a buckling edge


131


for confining an elastomer


221


of the inserting rod


2


.




One end of the inserting rod


2


coupled to the retaining seat


1


is installed with an inserting seat


21


. Two sides of the inserting seat


21


have stepped guide blocks


211


. The guide blocks


211


are exactly engaged with the two sliding grooves


12


of the retaining seat


1


. One end of the inserting seat


21


engaging to the buckling block


13


is formed with a receiving groove


22


. The receiving groove


22


is locked to the elastomer


221


through a stud P. The elastomer


221


is inclined upwards from a locking end.




Referring to

FIGS. 3

,


3


A,


3


B, and


3


C, one embodiment of the present invention is illustrated, after inserting the guide blocks


211


of the inserting rod


2


into the sliding grooves


12


of the retaining seat


1


; as the elastomer


221


of the inserting rod


2


is resisted by the buckling block


13


of the retaining seat


1


., the buckling edge


131


of the buckling block


13


can press the outward inclined elastomer


221


. After the buckling edge


131


passes through the elastomer


221


, by the resilient force of the elastomer


221


, the elastomer


221


is buckled by the buckling edge


131


and thus is confined. As a result, the inserting rod


2


is retained in the interior of the retaining seat


1


.




Two sides of the via hole of the wire connecting box have buckling groove D


11


, and two sides of the inserting portion corresponding to at two sides of the via hole have buckling protrusions for positioning the retaining seat.




The present invention is thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the present invention, and all such modifications as would be obvious to one skilled in the art are intended to he included within the scope of the following claims.
