Description

A kind of lamp holder sleeve pipe

Technical field:

The utility model relates to technical field of lamps, relates in particular to a kind of lamp holder sleeve pipe.

Background technology:

In the use of light fixture, in order better lamp holder to be connected with miscellaneous part,, can use a sleeve pipe usually especially in the field of floor lamp, lamp holder better is supported on the support of floor lamp; See Fig. 1, Fig. 2, present employed sleeve pipe mainly is made up of the outer tube 1 of metal, the pipe cap 202 of trapping, last sleeve cap 201, central siphon 3 and screw 5, during use, to trap pipe cap 202 and last sleeve cap 201 is set in outer tube 1 two ends, central siphon 3 passes the pipe cap 202 of trapping, outer tube 1 and last sleeve cap 201, and central siphon 3 two ends are fixed together with will trap pipe cap 202, outer tube 1 and last sleeve cap 201 of screw 5; But also there are a lot of deficiencies in this kind structure: at first, the security performance of metal sleeve is good inadequately; Secondly, in assembling process, because the use amount of light fixture is bigger, the use amount of sleeve pipe is also very big simultaneously, and in the prior art, need be at the outer tube two ends fit on sleeve caps all, relatively large thereby work takes time and effort, the production cost of sleeve pipe is higher; Especially after sleeve pipe has assembled, in use,, make whole lamp decoration attractive in appearance inadequately because screw exposes.

The utility model content:

The purpose of this utility model is at the deficiencies in the prior art, and a kind of lamp holder sleeve pipe of with low cost, good looking appearance is provided.

The utility model is achieved by following technology:

A kind of lamp holder sleeve pipe comprises central siphon, screw, and the central siphon outer surface is provided with screw thread; Also comprise a plastic cement that offers centre bore trap pipe cap and plastic cement outer tube, one end of plastic cement outer tube is provided with the plastic cement catch from port 3～10mm place, offer the catch centre bore on the plastic cement catch, central siphon passes centre bore, plastic cement outer tube and the catch centre bore on the pipe cap of trapping successively, and by in central siphon two ends connecting screw and the pipe cap of will trapping, central siphon and plastic cement outer tube are connected in one.

Wherein, an end of described plastic cement outer tube is provided with the plastic cement catch from port 4～8mm place.

The side that described plastic cement catch deviates from screw is provided with at least two fins, and fin is provided with on the circumference of plastic cement catch.

Described plastic cement catch is provided with 8 fins, and 8 fins are arranged on the circumference of plastic cement catch equably.

The end outer surface that described plastic cement outer tube is provided with the plastic cement catch be provided with decorate stupefied.

The length of described plastic cement outer tube is 20～100mm

The beneficial effects of the utility model are: the plastic cement that the utility model comprises central siphon, screw, offer centre bore trap pipe cap and plastic cement outer tube, and the central siphon outer surface is provided with screw thread; One end of plastic cement outer tube is provided with the plastic cement catch from port 3～10mm place; The utility model utilizes the one-body molded plastic cement outer tube of preparing of plastic cement, the insulating properties of sleeve pipe have not only been improved, make in its use security performance higher, and be provided with this structure of plastic cement catch from plastic cement outer tube port 3～10mm place, in large batch of production, by the integrated through injection molding moulding, make production cost reduce greatly; Especially when reality is used, screw is arranged in the groove that forms between plastic cement catch and the plastic cement outer tube port, rather than exposes, thereby makes that the monnolithic case of lamp body is more attractive in appearance, simultaneously in assembling, owing to not needing again many fit ons sleeve cap to save a large amount of production times; The plastic cement outer tube end outer surface that is provided with the plastic cement catch is provided with and decorates stupefiedly in addition, and this decorates stupefied mainly is for symmetrical with the pipe cap of trapping of the plastic cement outer tube other end, makes Total tune attractive in appearance; In a word, the utility model is not only reasonable in design, simple in structure, and good looking appearance, and especially with low cost, security performance is higher.
