Abstract
Abstract A ceiling lamp junction box double-constraint lighting rod mounting structure comprised of sockets installed through openings in the side of a junction box and plug-ended rods inserted into each socket. Each plug-ended rod has catch holes respectively formed in the top surface and two sides of its tip and, correspondingly, a spring and a retaining element are installed at the top ends and the lateral ends of each socket. When the retaining elements are their the normal state, the free ends of the retaining elements are pushed into the bores of the sockets by tensile components. After a plug-ended rod is inserted into the bore of a socket, the catch holes at its tip are respectively infixed by the engaging end of the spring and the free ends of the retaining elements projecting slightly into the bore such that the plug-ended rod is maintained in place by both the spring and the retaining elements and cannot be pulled out while mechanically constrained within the socket. Furthermore, since the junction box and the plug-ended rods can be disassembled and separately set aside, this minimizes overall shipping and storage dimensions. Following purchase, users only have to insert the plug-ended rods into the sockets of the junction box and no additional fasteners or tools are required to thereby facilitate do-it-yourself assembly convenience.

Claim 3
Dependent Claim
43 words
As mentioned in claim 1 of the ceiling lamp junction box double-constraint lighting rod mounting structure of the invention herein, the said sockets have a slotway disposed in each of their two sides that provides for the insertion of the said retaining elements.
Claim 4
Dependent Claim
91 words
As mentioned in claim 1 of the ceiling lamp junction box double-constraint lighting rod mounting structure of the invention herein, each said socket retaining element has one end hinged to a mounting hole of the said socket and the other end is contoured into a follower section that rests against the said tensile component; and each said tensile component is a C-shaped member constructed of a thin sheet of material having an impelling end that extends laterally from its center section and is seated against the said retaining element follower sections.
Claim 5
Dependent Claim
87 words
As mentioned in claim 1 of the ceiling lamp junction box double-constraint lighting rod mounting structure of the invention herein, the said free ends of the retaining elements hinged to the said sockets are of an angled arrangement such that they project into the interior section of the said bores and the curved said engaging ends of the said springs fastened to the top surfaces of the said socket platforms are of a slanted arrangement such that they extend into the said cutaways of the said platforms.
Claim 6
Dependent Claim
40 words
