Abstract

The utility model relates to a glass insulator assembling screw lamp holder in electric light source industry. The glass insulator assembling screw lamp holder is mainly composed of a metallic lamp holder casing (4), a glass insulator (1) and a contacting copper cap (2), wherein the glass insulator (1) is matched with the metallic lamp holder casing (4) in a moveable thread mode; the contacting copper cap (2) is closely matched with a cone salient (3) of the glass insulator in a tridimensional mode. The utility model has the advantages of protecting the glass insulator from being damaged by the lamp holder casing (4) when the lamp holder casing is processed at a back way, increasing the product qualification rate and extending the service life.

Description

Glass insulator assembled rib-loop lamp holder

The utility model relates to a kind of glass insulator assembled rib-loop lamp holder of electric light source industry.

The glass insulator rib-loop lamp holder that uses in the electric light source industry is that the whole compacting of glass insulator and lamp shell forms at present, and lamp holder contact copper cap is connected with the glass insulator level.Owing to adopted above-mentioned connected mode, make the metallic lamp holder shell carry out road, back processing under the state of glass insulator being connected with, very easily bump and glass decreases, cause a large amount of substandard products and waste product, in use contact the copper cap and very easily come off, influence product useful life.

The purpose of this utility model provide a kind of can the dismounting glass insulator, useful life the glass insulator assembled rib-loop lamp holder that prolongs.

For achieving the above object, technical solutions of the utility model are that this glass insulator assembled rib-loop lamp holder mainly is made up of metallic lamp holder shell, glass insulator, contact copper cap, glass insulator and metallic lamp holder shell are the movable mated condition of rib-loop, the three-dimensional pressure of contact copper cap covers in the glass insulator taper convex protrusion, be the state of closely cooperating, the glass insulator inwall is the more piece state of falling the funnel, and the centre is provided with two grooves being convenient to install.

After having adopted said structure,, prevented the too much damage that causes because of collision, improved the qualification rate of product because glass insulator is to finish laggard luggage in metallic lamp holder shell processed to join.The three-dimensional pressure of contact copper cap covers in the tapered convex protrusion of glass insulator, and it is closely cooperated, and difficult drop-off has prolonged lamp holder useful life.

Below in conjunction with drawings and Examples the utility model is described in detail.

Fig. 1 is the utility model front view;

Fig. 2 is the utility model phantom;

Fig. 3 is a glass insulator front view in the utility model;

Fig. 4 is a glass insulator A-A cutaway view in the utility model;

Fig. 5 is a glass insulator upward view in the utility model.

Fig. 1, a kind of glass insulator assembled rib-loop lamp holder shown in Figure 2, top is for closely pressing the contact copper cap 2 that covers in the tapered convex protrusion 3 of glass insulator, and the bottom is divided into metallic lamp holder shell 4, swells 5 for the glass insulator camber between the two.Glass insulator by being threaded into of matching, rises to metallic lamp holder shell 4 tops until the following bottom line of glass insulator arc protuberance 5 from metallic lamp holder shell 4 end openings.

Glass insulator 1 shown in Figure 3, top are the tapered convex protrusion 3 of glass insulator, and middle is glass insulator camber protuberance 5, are the assembling screw thread 6 through blasting treatment outside the bottom.

Fig. 4, glass insulator 1 shown in Figure 5, inner chamber is the glass insulator inwall 9 that is the more piece state of falling the funnel, the state of centre bore 7 likeness in form inner chamber handstand spout of funnels, and there are two corresponding grooves 8 at the inwall middle part, use a flat mouthful instrument to insert in two grooves 8 the rotary glass insulator simultaneously.
