Abstract
A plastic part of lamp tube comprises an upper plastic part and a lower part piece; the upper plastic part and the lower plastic part are respectively connected with a connecting end. At least four convex points are uniformly arranged on the same circumference of the inner wall of the connecting end of the upper plastic part the upper plastic part, a plurality of concave grooves matched with the convex points are arranged on the same circumference of the outer wall of the connecting end of the lower plastic part; the concave grooves are arranged sequentially and the total radian of the concave grooves is more than 60 degrees. As the plastic part of lamp tube adopts the technical proposal, and when the upper plastic part is connected with the lower plastic part, the upper plastic part can be inserted into the lower plastic part in any direction; meanwhile, at least a lock buckle connecting point is guaranteed; when better structure is adopted, at least two lock buckle connecting points are guaranteed.
Description
Technical field
The utility model relates to a kind of light fixture, particularly a kind of plastic part of lighting tube.
Background technology
Plastic part of lighting tube comprises working of plastics and following working of plastics, and last working of plastics and following working of plastics respectively are provided with a link, and last working of plastics links to each other by its link snap close with following working of plastics.Fluorescent tube is installed in down on the working of plastics.In the production process of electricity-saving lamp, there is one will go up the work that working of plastics is connected with following working of plastics.The last working of plastics of prior art and following working of plastics generally are to adopt single snap close point or line snap close to link to each other, in assembling process accurately contraposition just to reach snap close continuous.Because the automation numerical assembling machine needs the directionless location of 360 degree, in addition according to the specification requirement of product, last working of plastics is with after following working of plastics is connected, and reach stretching resistance 〉=4 kilogram, anti-rotational force 〉=3 newton's requirement.The last working of plastics of prior art and following working of plastics can not adapt to the automation assembling owing to its structural reason.
The utility model content
The purpose of this utility model exactly in order to solve the problems referred to above that prior art exists, provides a kind of plastic part of lighting tube that can realize the automation assembling.
The technical solution of the utility model is: a kind of plastic part of lighting tube, comprise working of plastics and following working of plastics, last working of plastics and following working of plastics respectively are provided with a link, last working of plastics links to each other by its link snap close with following working of plastics, be characterized in: the described inwall of going up the link of working of plastics evenly is provided with at least four salient points on same circumference, the described outer wall of the link of working of plastics down is provided with the adaptive groove of a plurality of and above-mentioned salient point on same circumference, the continuous arrangement of a plurality of grooves and its shared total arc length are more than 60 degree.
The described salient point of going up on the working of plastics has the head that dwindles, and this head has slick and sly edge; Groove on the described working of plastics down has flaring enlarging, and this enlarging has slick and sly edge.
The described salient point of going up on the working of plastics is hemisphere; Groove on the described working of plastics down is hemisphere.
The described salient point of going up on the working of plastics is four; Groove on the described working of plastics down is covered with whole circumference.
Plastic part of lighting tube of the present utility model is owing to adopted above technical scheme, in the time will going up working of plastics and be connected with following working of plastics, last working of plastics can insert working of plastics down from arbitrary orientation, and guarantee to have at least a snap close tie point, under the situation that adopts preferred construction, can guarantee to have at least two snap close tie points, have very strong stretching resistance and twisting resistance.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, plastic part of lighting tube of the present utility model comprises working of plastics 1 and following working of plastics 2, and last working of plastics 1 and following working of plastics 2 respectively are provided with a link 11,21, and last working of plastics links to each other by its link snap close with following working of plastics.The inwall of the link 11 of last working of plastics evenly is provided with at least four salient points 111 on same circumference, the basic configuration of this salient point can be circular, square or prismatic, hemisphere preferably, but all have a head that dwindles, and this head has slick and sly edge.The outer wall of the link of following working of plastics is provided with the adaptive groove 211 of a plurality of and above-mentioned salient point on same circumference, the basic configuration of this groove can be circular, square or prismatic, preferably hemisphere has flaring enlarging but all have one, and this enlarging has slick and sly edge.The continuous arrangement of a plurality of grooves and its shared total arc length are more than 60 degree.
Most preferred embodiment of the present utility model as shown in drawings, the salient point 111 on it on working of plastics is four and is evenly distributed on the same circumference that the groove 211 on the following working of plastics is covered with whole circumference.In the time of can guaranteeing that like this working of plastics 1 is connected with following working of plastics 2, last working of plastics 1 can insert working of plastics 2 down from arbitrary orientation, and guarantees that 4 snap close tie points are arranged, and has very strong stretching resistance and twisting resistance.
Claims (4)
