Detailed Implementation

[0019] Please see Figures 1-4A retractable recessed spotlight includes a spotlight tube 1, a displacement groove 6 at the bottom of the spotlight tube 1, and a storage groove 5 at the top of the inner cavity of the displacement groove 6. By setting the storage groove 5 and the displacement groove 6, the installation space requirements of the electric push rod 3 and the displacement space requirements of the mounting plate 4 can be met respectively. The electric push rod 3 is fixedly installed in the inner cavity of the storage groove 5. By setting the electric push rod 3, the height of the spotlight head 2 can be flexibly adjusted by telescoping and displacing in the working state. The output end of the electric push rod 3 and located in the inner cavity of the displacement groove 6 is fixedly installed with a mounting plate 4. The bottom of the mounting plate 4 and located at the bottom of the spotlight tube 1 is provided with the spotlight head 2. An anti-detachment assembly mechanism 7 is installed between the spotlight head 2 and the mounting plate 4.

[0020] Please see Figure 2 , Figure 4 and Figure 5 The anti-detachment assembly mechanism 7 includes an elastic locking block 704 and a screw sleeve 708. There are several elastic locking blocks 704, all of which are fixedly connected to the top of the spotlight head 2. There are two screw sleeves 708. By setting the screw rod 703 and the screw sleeve 708, the screw rod 703 can be used for thread transmission. When the screw sleeve 708 is driven to rotate, the screw rod 703 can be pushed out or moved into the screw sleeve 708.

[0021] Please see Figure 2 , Figure 4 and Figure 5 The inner cavity of the screw sleeve 708 is threadedly connected to the screw rod 703. The bottom of the screw rod 703 and the top of the screw sleeve 708 are both equipped with universal joints 702. By setting the universal joints 702, the screw sleeve 708 can be movably connected to the mounting plate 4, and the pressure plate 706 can be movably connected to the auxiliary plate 710.

[0022] Please see Figure 2 , Figure 4 and Figure 5 The screw sleeve 708 is movably connected to the mounting plate 4 via the universal joint 702, and the screw 703 is movably mounted with the auxiliary plate 710 via the universal joint 702;

[0023] Please see Figure 2 , Figure 4 and Figure 5 A lead screw 701 is movably installed at the center of the top of the auxiliary plate 710. A pressure plate 706 is threaded on the bottom of the surface of the lead screw 701. By setting the lead screw 701 and the pressure plate 706, the threaded transmission function can be achieved. When the lead screw 701 is driven to rotate, the pressure plate 706 can be moved up and down.

[0024] Please see Figure 2 , Figure 4 and Figure 5The top of the auxiliary plate 710 is provided with a slot 707 that works with the elastic block 704. By setting the elastic block 704 and the slot 707, the spotlight head 2 can be quickly positioned and installed on the auxiliary plate 710 by utilizing the material properties of the elastic block 704 during installation. The top of the auxiliary plate 710 is fixedly connected with a positioning rod 709. The surface of the pressure plate 706 is provided with a positioning hole 705 that works with the positioning rod 709. By setting the positioning hole 705 and the positioning rod 709, the positioning guide function can be used to ensure the stability of the vertical displacement of the pressure plate 706.

[0025] The pressure plate 706 is shaped like a frustum, and the diameter of its bottom surface is smaller than the diameter of its top surface;

[0026] The bottom of the lead screw 701 has a smooth design and is movably connected to the auxiliary plate 710 via a bearing. This design not only allows the lead screw 701 to rotate flexibly, but also prevents the lead screw 701 from dislodging from the auxiliary plate 710 due to linear displacement.

[0027] The outer ring of the threaded sleeve 708 is fixedly connected to a push rod, and the top of the lead screw 701 is fixedly connected to an anti-slip torsion block. The presence of the push rod and the anti-slip torsion block makes it convenient for the operator to drive the threaded sleeve 708 or the lead screw 701 to rotate.

[0028] In practical applications, both the spotlight tube 1 and the spotlight head 2 are equipped with power plugs with cables. Before installing the spotlight head 2, the two power plugs need to be connected and installed in advance so that the spotlight head 2 can be connected to the external mains power.

[0029] In use, all components are in their initial state. Based on actual lighting requirements, the electric push rod 3 can be extended to expose the anti-detachment assembly mechanism 7 from the displacement groove 6. Then, the threaded sleeve 708 is driven to rotate and clamp the screw 703. At this point, the overall length of the screw 703 and threaded sleeve 708 changes, causing the auxiliary plate 710 to be in its initial tilted state. Then, the spotlight head 2 moves upward to contact and adhere to the pressure plate 706. The elastic locking block 704 passes through the locking groove 707 and is positioned above the auxiliary plate 710, driving the lead screw 701 to rotate. With the cooperation of the positioning rod 709 and the positioning hole 705, the light can be... This causes the pressure plate 706 to move steadily downwards, contacting and pressing the elastic block 704. The elastic block 704 undergoes elastic deformation. In this state, the spotlight head 2 cannot detach from the pressure plate 706 at will. During the use of the equipment, the height of the bottom of the spotlight head 2 can be changed by controlling the electric push rod 3, which better meets the actual needs of the user. When the spotlight head 2 needs to be repaired, simply drive the lead screw 701 to rotate, causing the pressure plate 706 to move upwards, which will lower the spotlight head 2 and disengage the elastic block 704 from the slot 707, making it convenient to disassemble the spotlight head 2.

[0030] In summary, this retractable recessed spotlight, by incorporating a spotlight head 2, an electric push rod 3, a mounting plate 4, and an anti-detachment assembly mechanism 7, solves the problems of basic spotlights not being able to combine retractability with functionality, having a limited overall range of use, and being unable to quickly disassemble and assemble the light-emitting components, while its overall fixed design affecting the convenience of subsequent maintenance.
