Description

Lamp socket structure

The invention relates to a lamp socket, in particular to a lamp socket structure which can ensure the smoothness and stability of assembling the lamp tube and can effectively improve the stability after assembling the lamp tube.

As shown in FIG. 8, it is a conventional lamp socket, which is mainly composed of a base 81, a first spring 82, a second spring 83, a pushing member 84, a movable cover 85, and a panel 86. The first spring 82 and the second spring 83 are axially received on the same axis line of the base 81, and the first spring 82 supports the pushing member 84, and the second spring 83 passes through the pushing member 84 to support the movable cover 85, and finally covers the base 86 with the panel 86 to complete the assembly.

However, after the assembled lamp socket is assembled, as shown in FIG. 9, the pushing member 84 and the second spring 83 of the first spring 82 are simultaneously supported on the central portion of the movable cover 85, and The movable cover 85 is not supported by any two sides, so that the movable cover 85 is easily deflected due to uneven force, which not only affects the smoothness and smoothness of the movable cover 85 when moving axially. There is also a problem of poor contact and insufficient stability of the movable cover 85 and the lamp tube when they are topped.

In addition, the panel 86 of the conventional lamp socket is mainly disposed in each positioning hole 811 of the base 81 by using a plurality of positioning posts 861, so that the panel 86 is positioned on the base 81, and the movable cover is The first and second springs 82, 83 are compressed. However, since the first and second springs 82, 83 are compressed by the movable cover 85, a reaction force is generated in the direction of the panel 86 at the same time, which is easy to cause. After the panel 86 is erected by the reaction force for a long time, the positioning post 861 is gradually forced out of the positioning holes 811 to break the positioning state of the panel 86 and the base 81.

In view of this, how to solve the above problems is the primary problem to be solved by the present invention. Therefore, the inventor of the present invention finally has the invention after continuous hard thinking and trial work.
