[0002] In the lighting field, spotlights are widely used in home decorative lighting (such as living room background walls and display cabinet lighting), commercial space lighting (such as shopping mall windows and exhibition hall exhibit lighting) and industrial local lighting due to their strong light focusing and controllable illumination direction.

[0003] Currently, spotlights are typically installed in the recessed openings of the ceiling lights. After installation, the lighting height and angle of the spotlight cannot be adjusted, which limits its use and makes it unsuitable for different lighting scenarios. Therefore, we need to propose a retractable and adjustable recessed spotlight. Utility Model Content

[0004] The purpose of this invention is to provide a retractable and adjustable recessed spotlight. Pushing the lamp body upwards compresses the connecting post at the top, causing the connecting post to press against the locking structure, thus releasing the connection between the connecting post and the lamp housing. This allows the connecting post to slide within the lamp housing, enabling adjustment of the spotlight's illumination height. When the connecting post moves out of the lamp housing's inner cavity, the vertical angle support for the connecting post is removed. Moving the connecting post allows it to rotate on the surface of the adjusting post via the connecting bracket, thus adjusting the spotlight's angle. This design allows for adjustment of the spotlight's illumination height and angle after installation, preventing limitations on illumination height and angle during use and making it suitable for different lighting scenarios, thereby solving the problems mentioned in the background art.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-8 This utility model provides a technical solution: a retractable and adjustable embedded spotlight, including a lamp housing 1, a movable hole 4 at the top of the lamp housing 1, a power cord 5 in the inner cavity of the movable hole 4, a reset structure 2 for assisting the power cord 5 in resetting on the outer surface of the power cord 5, a lamp holder 6 at the bottom of the lamp housing 1, a lamp body 7 bolted to the top of the lamp holder 6, and the lamp body 7 is electrically connected to the power cord 5, a connecting post 8 bolted to the top of the lamp body 7, and the surface of the connecting post 8 is slidably connected to the inner cavity of the lamp housing 1, an adjustment groove 9 is provided on the surface of the connecting post 8, an adjustment frame 10 is integrally formed in the inner cavity of the adjustment groove 9, a fixing structure 3 for fixing the angle is provided on the surface of the adjustment frame 10, an adjustment post 11 is rotatably connected to the inner cavity of the adjustment frame 10, and a locking structure 12 for locking the top of the inner cavity of the lamp housing 1 is provided at the top of the adjustment post 11;

[0028] Install the spotlight in the recessed lighting hole in the ceiling, push the lamp body 7 upward, and the lamp body 7 will push the connecting column 8 upward. The connecting column 8 will press the locking structure 12, and after pressing, the locking structure 12 will release the connection between itself and the lamp housing 1. Pull the lamp body 7 out of the lamp housing 1 by hand. The position of the connecting column 8 in the lamp housing 1 can be adjusted. After moving the connecting column 8 out of the inner cavity of the lamp housing 1, move the connecting column 8 to drive the adjustment bracket 10 to rotate on the adjustment column 11, thereby adjusting the illumination angle of the spotlight. The above scheme allows the illumination height and illumination angle of the spotlight to be adjusted after installation, avoiding the limitation of illumination height and illumination angle when the spotlight is used, and making it suitable for different illumination scenarios.

[0029] The reset structure 2 includes a movable sleeve 21 fitted onto the surface of the power cord 5. A fixed sleeve 22 is provided at the top of the movable sleeve 21. The inner cavity of the fixed sleeve 22 is fixedly connected to the outer surface of the power cord 5. A spring 23 is also fitted onto the outer surface of the power cord 5, and the spring 23 is located between the movable sleeve 21 and the fixed sleeve 22. When the connecting post 8 moves downward, it can simultaneously drive the power cord 5 to move downward. The fixed sleeve 22 on the power cord 5 moves downward synchronously. The fixed sleeve 22 compresses the spring 23, and the spring 23 compresses the movable sleeve 21, thus energizing the spring 23. When the connecting post 8 moves upward, the spring 23 can release and push the fixed sleeve 22 at the top to move upward, so that the top of the power cord 5 generates tension, causing the power cord 5 to rise, thus preventing excess power cord 5 from getting tangled inside the lamp housing 1 and causing interference.

[0030] The fixing structure 3 includes support holes 31 on both sides of the adjusting frame 10 and a connecting hole 32 at the bottom of the adjusting column 11. The support holes 31 and the connecting hole 32 are fixed together by bolts and nuts. After adjusting the position of the adjusting frame 10 on the adjusting column 11, the bolt is inserted from the support hole 31 at one end, passes through the connecting hole 32, and exits from the support hole 31 at the other end and is bolted to the nut. By continuously tightening the bolt and nut, the two sides of the adjusting frame 10 are squeezed, increasing the friction between the adjusting frame 10 and the adjusting column 11, thereby achieving the positioning of the adjusting frame 10 on the adjusting column 11.

[0031] A protective shell 13 is fitted on the outer surface of the connecting post 8. A connecting block 14 is integrally formed on the inner side wall of the protective shell 13. A connecting groove 15 that matches the connecting block 14 is also provided on the outer surface of the connecting post 8. The protective shell 13 can protect the position of the connecting post 8. The connecting block 14 and the connecting groove 15 can be used to combine or disassemble the protective shell 13 and the connecting post 8 by snap-fitting, which facilitates the assembly and disassembly of the protective shell 13 and the connecting post 8.

[0032] The top of the protective shell 13 is provided with an adjustment hole 16, which is aligned with the position of the adjustment groove 9. The adjustment hole 16 can be used in conjunction with the adjustment groove 9 to avoid interference or obstruction of the adjustment column 11 by the protective shell 13.

[0033] The locking structure 12 includes a push-button latch 121 and a T-shaped block 122 adapted to the latch. The bottom end of the push-button latch 121 is bolted to a support base 123 adapted to the lamp housing 1. The bottom end of the support base 123 is fixedly connected to the top end of the adjusting column 11. The T-shaped block 122 is integrally formed at the top end of the inner cavity of the lamp housing 1. When locking, by pushing the adjusting column 11 upwards, the adjusting column 11 pushes the inner cavity of the push-button latch 121 into contact with the T-shaped block 122 via the support base 123. 2. Press the center of the push-button latch 121 to lock the T-block 122 on both sides. When releasing, push the support base 123 upward again to press the T-block 122 on the push-button latch 121 again. This releases the latch from the T-block 122, allowing the connecting post 8 to be adjusted in the inner cavity of the lamp housing 1, thus achieving the extension and retraction adjustment of the spotlight. The push-button latch 121 and the T-block 122 are commonly used structures in existing designs.

[0034] The support base 123 has a fixing hole on its surface and a cavity inside. An elastic ball 17 is installed inside the cavity of the support base 123, with one end of the elastic ball 17 extending outside the fixing hole. The lamp housing 1 has five sets of slots 18 that fit the elastic ball 17 inside its cavity. When the support base 123 moves downwards inside the lamp housing 1, the position of the support base 123 within the lamp housing 1 is determined when the surface of the elastic ball 17 inserts into the cavity of the slot 18. The elastic ball 17 helps to improve the stability of the lamp housing. Provides a certain supporting force to position the support base 123 within the lamp housing 1, thereby positioning the extended position of the spotlight. When the elastic top bead 17 is subjected to force, it can move out of the inner cavity of the slot 18 and move to the position of another set of slots 18. With the setting of five sets of slots 18, the adjustment range of the elastic top bead 17 can be adjusted in four levels. When the support base 123 drives the elastic top bead 17 to move downward to the inner cavity of the third set of slots 18, the connecting post 8 can be moved out of the inner cavity of the lamp housing 1, and the illumination angle of the spotlight can be adjusted.

[0035] The lamp housing 1 includes a housing 111 and a cover plate 112. The inner side wall of the housing 111 is provided with a fixing groove 113. The inner cavity of the fixing groove 113 is provided with an elastic fixing plate 114 that is adapted to the fixing groove 113. The elastic fixing plate 114 is integrally formed on the bottom end of the cover plate 112. Through the cooperation of the fixing groove 113 and the elastic fixing plate 114, the lamp housing 1 and the cover plate 112 can be assembled and disassembled by snap-fit, which facilitates the disassembly and assembly of the cover plate 112 and the housing 111, and makes it convenient to repair and replace the lamp housing 1.

[0036] This embodiment also includes a second spring 19 between the cover plate 112 and the support base 123. The second spring 19 is sleeved on the power cord 5. With the setting of the second spring 19, when the push-type latch 121 releases the T-shaped block 122, the second spring 19 can push the support base 123 to move downward, so that the lamp body 7 pops out from the lamp housing 1.

[0037] The elastic fixing plate 114 is L-shaped, and the lower surface of the elastic fixing plate 114 has a beveled surface. When the elastic fixing plate 114 contacts the top of the housing 111, the beveled surface acts as a guide, causing the elastic fixing plates 114 on both sides to be pressed inward. When it moves to the position of the fixing groove 113, the elastic fixing plates 114 on both sides return to their original position, so that one end of the elastic fixing plate 114 is inserted into the inner cavity of the fixing groove 113, which facilitates the installation of the cover plate 112 and the housing 111.

[0038] In practical use: First, install the spotlight inside the recessed lighting opening in the ceiling. When the spotlight needs to be adjusted in height, push the lamp body 7 upwards to press against the connecting post 8. The connecting post 8, through the adjusting post 11, causes the support base 123 to rise. The support base 123 then causes the push-button latch 121 to rise. The inner cavity of the push-button latch 121 contacts the T-block 122, and the T-block 122 presses against the center of the push-button latch 121, causing the two sides of the push-button latch 121 to release from the T-block 122. The spring 19 can then push the support base 123 downwards, causing the lamp body 7 to pop out of the lamp housing 1. Then, pull the lamp body 7 by hand through the connecting post 8 to move the support base 123 downwards. 23 moves within the lamp housing 1. By adjusting the position of the elastic top bead 17 in different slots 18, the illumination height of the spotlight can be adjusted. When the support base 123 moves the elastic top bead 17 downward to the inner cavity of the third set of slots 18, the connecting post 8 can be moved out of the inner cavity of the lamp housing 1. When adjusting the illumination angle, the connecting post 8 is moved, causing the adjustment frame 10 to move on the adjustment post 11. By adjusting the angle between the adjustment frame 10 and the adjustment post 11, the angle adjustment of the spotlight can be completed. Through the above scheme, the illumination height and illumination angle of the spotlight can be adjusted after installation, avoiding the limitation of illumination height and illumination angle when the spotlight is used, and making it suitable for different illumination scenarios.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
