Abstract

The utility model discloses a lamp burner connecting structure of a lamp cap, which is arranged on a holder of the lamp cap; the inside of the lamp burner is hollow so as to form a cavity, the wall of the lamp burner is provided with a vertical locating bump; the top of the holder is provided with a convex column which is provided with a vertical locating groove matching with the locating bump; a clamping structure is arranged between the lamp burner and the holder so as to clamp the lamp burner and the holder together. When the connecting structure is assembled, only one clamping step is needed to finish the assembling process, so the step is rather convenient and simple; besides, the demounted connecting structure can be conveniently replaced so as to reduce unnecessary waste and better satisfy the requirements of environmental protection.

Description

The socket syndeton of lamp holder

Technical field

The utility model relates to a kind of light fixture, refers to a kind of socket syndeton of lamp holder especially.

Background technology

As shown in Figure 1, at present the lamp holder of light fixture such as electricity-saving lamp generally include interconnective socket 1 ' with base 2 ', this socket 1 ' be used for being connected with lamp socket, it generally is divided into screw type or bayonet type etc., and base 2 is then in order to hold various electric elements and to be used for fixing fluorescent tube.In the prior art, described socket 1 ' with base 2 ' the rivet mode that is connected to, though this connected mode connects very firmly, have following defective:

1. assembling the time need can be riveted by instrument even machine, and below socket the border generally need be provided with a plurality of riveting points 3 ', therefore not only time-consuming but also effort when assembling, thus the assembly cost of product is increased greatly.

2. described socket 1 ' finish with base 2 ' assembling in a single day, promptly can't dismantle, therefore when one of them damage and another is when also intact, also whole lamp holder must be abandoned, and no matter this damage takes place during fabrication or the consumer is when using, all can cause waste, also be unfavorable for environmental protection simultaneously.

The utility model content

The purpose of this utility model is to provide a kind of socket syndeton of lamp holder, and this syndeton makes the base assembling of socket and lamp holder easy, and detachable the replacing.

For achieving the above object, technical solution of the present utility model is:

A kind of socket syndeton of lamp holder, this socket is arranged on the base of lamp holder, thus its inner hollow forms cavity volume, and the chamber wall of described socket is provided with a locating convex block longitudinally; And described base top is provided with a projection, and this projection is provided with a longitudinal register groove and cooperates with the locating convex block of socket; Also be provided with the snap-in structure that both can be engaged between described socket and the base.

The chamber wall of described socket is provided with at least one grab; And being provided with at least one draw-in groove, the projection of described base engages with the grab of socket.

After adopting such scheme, therefore very convenient simple because the utility model, only needs step engaging to assemble and put in place during its assembling being arranged to dismountable syndeton between the socket of lamp holder and the base, thus can reduce assembly cost.And the locating convex block of described socket is with after the detent of base cooperates, and can limit that socket is relative with base to be rotated; And described socket can prevent that with after snap-in structure between the base engages both vertically break away from, and therefore this syndeton is very solid and reliable.Moreover, when one of them of socket and base damaged, only need order snap-in structure between the two to break away from, be about to both and separate, so that change one that damages, therefore can reduce unnecessary waste, more compliance with environmental protection requirements.

Description of drawings

Fig. 1 is the structural representation of existing lamp holder;

Fig. 2 is a three-dimensional exploded view of the present utility model;

Fig. 3 is a combination partial sectional view of the present utility model.

The specific embodiment

Consult Fig. 2 and shown in Figure 3, lamp holder described in the utility model comprises socket 1 and base 2.Wherein:

Described socket 1 periphery can be screw type or bayonet type, and it is in order to being connected with lamp socket, is example with the screw type among the figure; Thereby this socket 1 is a hollow forms cavity volume 11, and the wall of this cavity volume 11 is provided with a locating convex block 12 longitudinally, also is provided with at least one grab 13.

Described base 2 inside are in order to hold various electric elements (not shown)s, and the bottom is in order to install fluorescent tube; And its end, top, be provided with a projection 21, and this projection 21 is provided with a longitudinal register groove 22 and cooperates with above-mentioned locating convex block 12, and also being provided with at least one draw-in groove 23 on this projection 21 can engage with above-mentioned grab 13.

The utility model with the detent 22 of described socket 1 with the described base 2 of its locating convex block 12 alignings, is pushed downwards when assembling then, engages with the draw-in groove 23 of base 2 up to the grab 13 that makes socket 1, can assemble fully.This syndeton only needs step engaging to put in place when assembling, and is therefore very convenient simple, thereby can reduce assembly cost.And described locating convex block 12 can limit socket 1 and base 2 relative rotations with after detent 22 cooperates, and described grab 13 engages with draw-in groove 23, can prevent that socket 1 and base 2 vertically break away from, described its syndeton is very solid and reliable.Moreover when one of them of socket 1 and base 2 damaged, the grab 13 that only need make socket 1 broke away from the draw-in groove 23 of base 2, is about to both and separates, so that change one that damages, therefore can reduce unnecessary waste, more compliance with environmental protection requirements.

Need to prove that the grab 13 of described socket 1 also can replace by other snap-in structure with the draw-in groove 23 of base 2, for example engage protruding grain and engage groove or the like.
