Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the structural representation of existing step reference column;
Fig. 2 is the structural representation of reference column of the present utility model;
Fig. 3 is the mounting structure schematic diagram of reference column of the present utility model.
The specific embodiment
As shown in Figure 2, be the structural representation of heat sink reference column of the present utility model.This reference column is made up of location division 21, connecting portion 22 and the small end 23 of cylindricality, and wherein connecting portion 22 is between location division 21 and small end 23.This reference column can be one-body molded, thereby production and processing is simple and convenient.Certainly, also can will be spliced to form after the each several part segmental machining according to actual needs.
In above-mentioned reference column, the diameter of location division 21 is greater than the diameter of connecting portion 22, and the diameter of connecting portion 22 is greater than the diameter of small end 23.
The outer surface of connecting portion 22 can be processed into tapping structure, thereby this connecting portion 22 can be screwed to the locating hole of heat sink.
The height of location division 21 is greater than the spacing between heat sink and casing and less than spacing between heat sink and casing and casing thickness sum, and the locating hole of the diameter of this location division and casing match (usually more than or equal to 3 millimeters).The height of small end 23 is less than the thickness of lamp plate, and the locating hole of its diameter and lamp plate matches.The height of connecting portion 22 is more than or equal to the thickness of heat sink, and the locating hole of its diameter and heat sink matches.
As shown in Figure 3, be the schematic diagram of heat sink location structure of the present utility model, this location structure is used for location and installation lamp plate 31, heat sink 33.This location structure arrives casing 34 by a plurality of reference columns with heat sink 33 location and installation, and lamp plate 31 location and installation are arrived heat sink 33.
