LED (light emitting diode) lampshade connecting structure

Abstract

The invention relates to an LED (light emitting diode) lampshade connecting structure. The LED lampshade connecting structure comprises a lampshade and a lamp holder, wherein the lampshade is divided into a spherical notched inner cover and an annular outer cover, the outer diameter of the inner cover is equal to the inner diameter of the outer cover, and the outer cover is provided with an annular inner dustproof plate and an outer dustproof plate; the inner cover is provided with at least two fixing columns which are connected with the lamp seat, the axis of each fixing column is parallel to that of the inner cover, the fixing columns are uniformly distributed along the circumferential direction of the inner cover, the fixing columns are fixedly connected with the inner cover through connecting blocks, and the width of each connecting block is greater than or equal to the thickness of a clamping hook; the inner dustproof plate is provided with notches which are identical to the quantity of the connecting blocks, the notches are uniformly distributed along the circumferential direction of the inner dustproof plate, the side wall of each notch is provided with the clamping hook corresponding to the connecting blocks one by one, each connecting block is arranged on between the clamping hook and the top surface of respective notch, and the distance from the end part of a movable end of each clamping hook to the notch and the distance between the opposite side walls of the clamping hook are greater than the length of each connecting block. Compared with the prior art, the LED lampshade connecting structure has characteristics of relatively simple structure, relatively low preparation cost, simplicity in clamping connection, good application stability and long service life.

Description

technical field [0001] The invention belongs to the field of lighting equipment, in particular to an LED lampshade connecting structure for an LED lamp. Background technique [0002] LED is the abbreviation of the English name Light Emitting Diode, and the Chinese name is light emitting diode. [0003] Current LED lamps generally have a lampshade and a lamp holder, and there are multiple connection methods between the lampshade and the lamp holder, such as: screw connection, glue connection, dot connection, pressure ring thread connection, buckle connection and so on. However, when screw connection is used, the appearance of the lamp will be affected, and installation and later maintenance are more troublesome; and when adhesive connection is used, once connected, it cannot be disassembled, and the glue is expensive and contains volatile harmful organic compounds. It is beneficial to environmental protection. The glue has high requirements for workers during painting, and p...

[0004] But the rotary buckle type of the prior art, such as the publication number CN 103604099A, the title is the open text of the lamp connection structure and the lamp, the publication number is CN 102997602A, the title is the open text and the publication number of the refrigerator and its lighting lamp assembly is CN203405898U, The name is the structure described in the public text of the connection structure of the detector that does not require pre-alignment. The hook of the buckle structure in the first public text is protruding alone, which is prone to breakage during use. The stability is poor, the service life is also short, and the side of the hook is also provided with protrusions, because the thickness of the hook is uneven, injection molding defects are prone to occur during injection molding, and the yield is low; while the second public In the buckle structure in the text, since the hook protrudes radially inward and the groove is a groove with a side opening, it is necessary to strictly align the hook with the groove during assembly, otherwise it is not easy to attach the hook It is buckled with the card slot, so the installation is more troublesome, and an additional bump needs to be provided on the lamp holder to set the card slot, which increases the production cost; and the buckle structure in the third publication is more complicated in structure, and the card slot The hook is located inside the base, which makes the shape of the mold cavity more complex, resulting in a lower success rate of demoulding, and there is also a single protruding hook, which is prone to breakage during use, poor stability and long service life. also shorter question
