Description

Technical Field

[0001] The utility model relates to the technical field of spotlights, in particular to a track spotlight with an angle-adjustable self-locking structure. Background Art

[0002] Track spotlights are generally installed on conductive rails or brackets for decorative lighting. Generally, track spotlights include a lamp body, a track box, and a cantilever rod. The cantilever rod is rotatably connected to the lamp body and the track box at the same time. The cantilever rod can rotate relative to the lamp body and the track box to adjust the direction of light projection. In order to allow the cantilever rod to be positioned when the lamp body rotates and swings, the cantilever rod and the lamp body are contact-matched. For example, the cantilever rod is contact-rotated and installed on the lamp body. There is a large contact pressure between the cantilever rod and the lamp body. This structure can increase the friction between the cantilever rod and the lamp body, and at the same time, the lamp body can be rotated to adjust the direction of light projection, preventing the cantilever rod from shaking relative to the lamp body when the force is small.

[0003] However, after using it for a period of time, wear occurs between the cantilever rod and the lamp body, the contact pressure between the cantilever rod and the lamp body decreases, and the friction between the cantilever rod and the lamp body also decreases, making it difficult to reliably position the cantilever rod and the lamp body. The lamp body will also shake when subjected to a small force, causing the lighting area of ​​the lamp body to shake, resulting in a poor user experience. Utility Model Content

[0018] The following examples illustrate the present invention, but the present invention is not limited by these examples. Modifications to the specific implementation of the present invention or equivalent replacement of some technical features without departing from the spirit of the present invention should be included in the scope of the technical solution claimed for protection in the present invention.

[0019] like Figure 1-Figure 4As shown, the present embodiment provides an angle-adjustable track spotlight with a self-locking structure, comprising a track box 1, a cantilever seat 2 and a spotlight housing 3, wherein the upper end of the cantilever seat 2 is rotatably mounted on the lower end of the track box 1, and the spotlight housing 3 is swingably mounted on the lower end of the cantilever seat 2, a fixed seat 4 is arranged on the upper side of one end of the spotlight housing 3, a rotating shaft 5 is arranged on the fixed seat 4, a through hole 6 is arranged on the cantilever seat 2, the rotating shaft 5 is rotatably mounted in the through hole 6, and a self-locking mechanism is also arranged on the rotating shaft 5, and the self-locking mechanism can lock the rotating shaft 5 in the through hole 6.

[0020] In the utility model, the rotating shaft 5 can rotate through the through hole 6 to adjust the irradiation angle of the spotlight housing 3. After the angle is adjusted, the rotating shaft 5 is locked in the through hole 6 by the self-locking mechanism to fix the spotlight housing 3, prevent the spotlight body 3 from shaking, and optimize the user experience.

[0021] See also Figure 2-Figure 4 As shown, the self-locking mechanism includes a plurality of tooth grooves 21 evenly distributed along the circumference on the inner wall of the through hole 6, a cavity 22 is provided in the rotating shaft 5, a button 23 is provided on one side of the rotating shaft 5, the inner end of the button 23 extends into the cavity 22 and is provided with a latch tooth 24, one end of the latch tooth 24 extends out of the rotating shaft 5 and can be inserted into the tooth groove 21, and an elastic member 25 for making the button 23 and the latch tooth 24 include an outward shape is also provided in the cavity 22.

[0022] In the locked state, the elastic force of the elastic member 25 allows the button 23 and the latch tooth 24 to include an outward shape, thereby allowing the latch tooth 24 to remain engaged in the tooth groove 21, thereby locking the shaft 5; in the unlocked state, the button 23 is pressed inward to disengage the latch tooth 24 from the tooth groove 21, and the shaft 5 can rotate in the through hole 6.

[0023] Furthermore, one end of the latching tooth 24 that is inserted into the tooth groove 21 is provided with an inverted bevel 31 , so that the latching tooth 24 can be smoothly inserted into the tooth groove 21 .
