Abstract

The utility model relates to a lamp cap, in particular to a lamp cap used for both ends of an LED lamp tube. The lamp cap comprises a lamp cap end cover; the lamp cap end cover is provided with a rotating head; the rotating head can rotate relative to the lamp cap end cover; the rotating head is provided with a copper needle connected with a power supply; and the lamp cap end cover is provided with a connecting structure which is fixed with a lamp tube part. When the rotatable lamp cap is arranged on the lamp tube, the lamp cap end cover is fixed with the lamp tube part, the rotating head and the copper needle arranged on the rotating head are disposed on a lamp holder; when the irradiation angle of the lamp tube needs to be adjusted, only the lamp tube needs to be rotated and the lamp cap end cover and the rotating head rotate relatively, the whole lamp does not need to be installed and detached again, so that the use is convenient.

Description

A kind of rotatable lamp holder

Technical field

The utility model relates to lamp holder, especially the lamp holder of LED lamp tube ends use.

Background technology

Existing LED fluorescent tube lampshade two ends are equipped with lamp holder, be used for LED lamp plate power supply to lampshade inside, but existing lamp holder and lampshade are for fixedlying connected, after so the LED fluorescent tube is installed, its direction of illumination is fixed, and can't regulate, if regulate, need reinstall the lamp socket of LED fluorescent tube, complicated operation is loaded down with trivial details.

Summary of the invention

The utility model provides a kind of LED of adjusting fluorescent tube direction of illumination and rotatable lamp holder easy and simple to handle.

To achieve these goals, the utility model adopts following technical scheme:

It comprises a lamp holder end cap, and described lamp holder end covers installs a swivel head, and swivel head can be equipped with the copper pin that connects power supply with respect to the rotation of lamp holder end cap on the swivel head, and described lamp holder end is covered with the syndeton with the fluorescent tube partial fixing.

Preferably, described lamp holder end covers and is provided with a through hole, and described swivel head is located in the through hole rotatable with respect to the lamp holder end cap.

Preferably, described swivel head outside also is provided with the over cap that is used to protect the copper pin.

Preferably, described syndeton is a screw, and the screw of packing in the screw partly is connected with fluorescent tube.

Preferably, described lamp holder end covers and is provided with the scale that indicates the anglec of rotation.

Preferably, described scale is to have covered row's concave point in lamp holder end, and rail groove is arranged between concave point; The salient point that a correspondence is arranged on swivel head is after assembling is finished, during rotary lamp holder. and the salient point on the lamp holder is sliding in the rail groove. and when salient point ran to concave point, salient point slipped into concave point; This moment, swivel head was in stable state with respect to lamp holder lid end; When rotating fluorescent tube than great dynamics, salient point can skid off from concave point again.

Preferably, described scale relative position is provided with one and places restrictions on concave point, and the salient point of a correspondence is arranged on swivel head, and after assembling was finished, when the salient point with swivel head is installed on when placing restrictions in the concave point, swivel head was by locked.

Preferably, the described concave point place that places restrictions on indicates stop.

Owing to adopted said structure, in the time of on rotatable lamp holder installation of the present utility model and the fluorescent tube, lamp holder end cap and fluorescent tube partial fixing, swivel head and on the copper pin install with lamp socket on, when needs are regulated the irradiating angle of fluorescent tube, only need to rotate fluorescent tube, making relatively rotates between lamp holder end cap and the swivel head gets final product, need not the whole light fixture of dismounting again, easy to use.

Description of drawings

Fig. 1 is the utility model embodiment cap part structural representation;

Fig. 2 is the utility model embodiment lamp holder and lamp tube structure schematic diagram;

Fig. 3 is the utility model embodiment swivel head structural representation;

Fig. 4 is the utility model embodiment lamp holder end cap structural representation.

The utility model purpose, function and advantage will be in conjunction with the embodiments, are described further with reference to accompanying drawing.

The specific embodiment

As shown in Figure 1, present embodiment comprises a lamp holder end cap 1, one through hole 11 is arranged in the described lamp holder end cap 1, one swivel head 2 is installed in the through hole 11, swivel head 2 can be with respect to 1 rotation of lamp holder end cap, the copper pin 3 that connects power supply is installed on the swivel head 2, and described lamp holder end cap 1 is provided with the syndeton 12 with the fluorescent tube partial fixing.

Damage in transit for fear of the copper pin, described swivel head outside also is provided with the over cap 8 that is used to protect the copper pin.

In the present embodiment, described syndeton 12 is a screw, and the screw 4 of packing in the screw partly is connected with fluorescent tube.In the present embodiment, fluorescent tube partly comprises PC cover 5, LED lamp plate 6 and aluminum pipe 7, and lamp holder end cap 1 is fixing with aluminum pipe 7 by screw 4, and PC cover 5 is fixed on the aluminum pipe 7.

In order to make rotary manipulation more accurate, lamp holder end described in the present embodiment covers and is provided with the scale that indicates the anglec of rotation.

Present embodiment has row's concave point 13 on lamp holder end cap 1,13 of concave points have rail groove 14; The salient point 21 that a correspondence is arranged on swivel head 2, after assembling was finished, when rotating swivel head 2, the salient point 21 on the swivel head 2 was in 14 li slips of rail groove. and when salient point 21 ran to concave point 13, salient point 21 slipped into concave point 13; This moment, swivel head 2 was in stable state with respect to lamp holder lid end 1; Can tube end covers be shifted voluntarily because of reasons such as gravity; When rotating fluorescent tube than great dynamics, salient point 13 can skid off from concave point 21 again, realizes spinfunction.

In the present embodiment, described lamp holder end cap 1 high scale relative position is provided with one and places restrictions on concave point 15, and after assembling was finished, when the salient point 21 with swivel head 2 is installed on when placing restrictions in the concave point 15, swivel head 2 can not be rotated by locked.Described concave point 15 places that place restrictions on indicate stop.

So present embodiment in use, lamp holder end cap 1 and fluorescent tube partial fixing, swivel head 2 and on copper pin 3 install with lamp socket on, when needs are regulated the irradiating angle of fluorescent tube, only need to rotate fluorescent tube, making relatively rotates between lamp holder end cap 1 and the swivel head 2 gets final product.The swivel head salient point can be able to be realized non-rotatable fixed connection structure with respect to placing restrictions on the concave point installation in the occasion of getting rid of the rotation consideration.

The above only is a preferred embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to be done; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
