Description
Technical Field
The utility model relates to the technical field of lamps and lanterns, concretely relates to but angle regulation's blackboard lamp.
Background
The blackboard lamp is a type of blackboard lamp which is used more in a teaching scene, is arranged in front of a blackboard and is used for providing illumination for the blackboard. Among the prior art, the blackboard lamp of installation is generally installed on the top ceiling in blackboard the place ahead to make the blackboard lamp can be effectual for the blackboard provides the illumination, however, the light that from top to bottom shines causes the harm easily to mr's eyes. Therefore, it is required to develop a blackboard lamp with an adjustable angle.
SUMMERY OF THE UTILITY MODEL
Therefore, the utility model provides an but angle regulation's blackboard lamp to solve the problem that the light that from top to bottom shines caused the harm easily to mr's eyes that provides among the above-mentioned background art.
In order to achieve the above object, the present invention provides the following technical solutions: the utility model provides an angle adjustable's blackboard lamp, this blackboard lamp includes lamp stand and lamp shade, the lamp strip is installed to the lamp stand, have and the lamp stand with the lamp shade rotates to be connected.
Preferably, two baffles are fixedly mounted on two sides of the lamp holder, fixing grooves are formed in the baffles, fixing rings are arranged on the lampshade, and the fixing grooves are penetrated through bolts and matched with the fixing rings to limit the rotation angle of the lampshade.
Preferably, the two sides of the lamp holder are provided with rotating pins, and one end of the lampshade close to the lamp holder can be sleeved on the periphery of the rotating pins.
Preferably, the lampshade is arranged in an L shape.
Preferably, the lamp shade is arranged between the two baffles.
Preferably, the fixing ring is disposed at an inner side of the lamp housing.
Preferably, the retainer ring is provided with an open end.
Preferably, the inner ring of the fixed ring is provided with threads.
The utility model has the advantages that:
the angle adjusting operation is simple, the irradiation angle of light can be correspondingly adjusted by rotating the lampshade at different angles, so that different light-emitting angles can be obtained, the accurate control of the light-emitting angle of the blackboard lamp can be realized by controlling the rotating angle of the lampshade, and the angle adjusting precision is higher; in addition, through the position of utilizing screw rod and retainer plate's cooperation in order to restrict the lamp shade, the phenomenon that the angle rebounded can not appear after blackboard lamp goes out light angle adjustment promptly, and angle adjustment stability and reliability are higher.

Detailed Description
The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.
Referring to fig. 1-3, the utility model provides a pair of but angle regulation's blackboard lamp 300, this blackboard lamp 300 include lamp stand 100 and lamp shade 200, lamp strip 300 is installed to lamp stand 100, and lamp stand 100 still sets up lens 102, and this lens 102 is used for diffusing the light irradiation angle of lamp strip 300, and lamp stand 100 with lamp shade 200 rotates to be connected, lamp shade 200 can rotate around lamp stand 100 for shield light, and then change the angle that light shines.
Further, referring to fig. 1 and 3, two blocking plates 400 are fixedly mounted on both sides of the lamp socket 100, the blocking plates 400 are provided with fixing grooves 401, and the lamp shade 200 is provided with a fixing ring 201, and bolts pass through the fixing grooves 401 and are engaged with the fixing ring 201 to limit the rotation angle of the lamp shade 200.
The position of the lamp shade 200 is limited by the cooperation of the screw rod and the fixing ring 201, namely, the phenomenon of angle rebound can not occur after the light emitting angle of the blackboard lamp 300 is adjusted, and the stability and the reliability of the angle adjustment are higher.
Further, referring to fig. 2, the two sides of the lamp holder 100 are provided with the rotation pins 101, one end of the lamp shade 200 close to the lamp holder 100 can be sleeved on the periphery of the rotation pins 101, the lamp shade 200 rotates around the rotation pins 101 with the rotation pins 101 as supporting points, the lamp shade 200 shields light, and then the light irradiation angle is changed.
In the embodiment, the lamp cover 200 is configured as an "L" shape, and the lamp cover 200 of the "L" shape is convenient for shielding light.
It should be noted that the lamp shade 200 is disposed between the two baffles 400, the fixing ring 201 is disposed on the inner side of the lamp shade 200, and the inner ring of the fixing ring 201 is provided with a thread, and passes through the fixing groove 401 through a bolt to be connected with the fixing ring 201 through the thread, so as to limit the rotation angle of the lamp shade 200.
It should be specially noted that the fixing ring 201 is provided with an opening end 202, and the unclosed fixing ring 201 is adopted, so that bolts with different diameters can be conveniently matched, and the application range is wide.
The principle of the utility model is as follows:
the utility model discloses a use as follows: when using the utility model discloses the time, the manual work uses rotatory round pin 101 to rotate lamp shade 200 as the fulcrum, has adjusted suitable angle, passes fixed slot 401 and retainer plate 201 threaded connection through the bolt to restriction lamp shade 200's rotation angle, light angle change can reduce unnecessary light and produce the influence to mr's eyes.
The above description is only a preferred embodiment of the present invention, and any person skilled in the art may modify the present invention or modify it into an equivalent technical solution by using the technical solutions described above.
