[0024] Example

[0025] Reference Figure 1 , Figure 4 As shown, the utility model discloses an angle-adjustable lamp, comprising a base plate 10, a connecting rod 20 and a lampshade 30. The base plate 10 is provided with a plurality of mounting holes 102, and the mounting holes 102 are used to mount and fix the lamp on a ceiling or a display cabinet.

[0026] Reference Figure 1-4As shown, a sphere 202 is provided at one end of the connecting rod 20, and the other end is hinged to the base plate 10. Specifically, the base plate 10 fixes the second fixed plate 101, and a connecting block 203 is provided at the end of the connecting rod 20 away from the sphere 202. The connecting block 203 has a U-shaped notch, and the U-shaped notch is covered in the second fixed plate 101. The connecting block 203 is bolted to the second fixed plate 101, and the connecting rod 20 is installed on the base plate 10 through the bolt connection with the second fixed plate 101 through the U-shaped notch. The connecting rod 20 swings around the second fixed plate 101 by 0°-180°, and the angle of the connecting rod 20 can be fixed as needed.

[0027] Reference Figure 1-4 As shown, the back of the lampshade 30 is hingedly mounted on the base, and the base includes two pressing blocks 302. The two pressing blocks 302 are closed to form a spherical cavity, and the sphere 202 is rotatably placed in the spherical cavity. Specifically, a first fixing plate 301 is fixedly mounted on the back of the lampshade 30, and the first fixing plate 301 has a first fixing hole. The two pressing blocks 302 are hinged in the first fixing hole, and the two pressing blocks 302 are clamped on both sides of the first fixing plate 301. Bolts pass through the two pressing blocks 302 and the first fixing hole to lock them, and the two are locked on the first fixing plate 301. The two pressing blocks 302 can swing around the first fixing plate 30 by 10°-180°, and the fixed angle can be installed as needed. The two pressing blocks 302 have curved grooves 3021 on their end faces facing each other, and the two curved grooves 3021 are closed to form a spherical cavity with an opening. Before locking the two pressing blocks 302, the sphere 202 at one end of the connecting rod 20 is placed between the two curved grooves 3021. When the two pressing blocks 302 are pressed and closed, the sphere 202 is placed in the spherical cavity. When in use, the lampshade 30 is rotated around the sphere 202 to achieve fast and accurate switching of the lamp's illumination angle, which is more flexible than the existing base adjustment.

[0028] Reference Figure 1-4 As shown, the connecting rod 20 has a thread 201, a nut 204 is installed on the connecting rod 20, and a tower spring 205 is sleeved between the nut 204 and the lampshade 30. Specifically, under normal conditions, the nut 204 is placed on the side of the connecting rod 20 close to the bottom plate 10, and the tower spring 205 is in a relaxed state. At this time, the angle of the lampshade 30 can be rotated at will. When the illumination angle of the lamp needs to be always along the axial direction of the connecting rod 20, the nut 204 is tightened to move along one side of the connecting rod 20 and press the spring around the lampshade 30 to limit the inclination of the lampshade 30. The connecting rod 20 is perpendicular to the light-emitting surface of the lampshade 30, that is, the angle of the lampshade 30 is fixed. Compared with the existing adjustable angle lamps, when used as fixed angle lamps, it is easy to be accidentally touched to cause the illumination angle to deviate, and the utility model can be switched to a fixed angle lamp according to needs, avoiding the angle deviation caused by accidental touch, and further improving practicality.

[0029] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
