DETAILED DESCRIPTION

[0020] The technical scheme of the utility model will be described below with reference to the drawings and embodiments.

[0021] As Figures 1-4 shown, a small adjustable buried lamp of the utility model, including the lamp body 1, the inner chamber of lamp body 1 is equipped with heat dissipation module, heat dissipation module is equipped with light source 11, the outside wall of lamp body 1 is equipped with assembly slot 12, and the through hole 13 is opened in assembly slot 12, and the through hole 13 penetrates the inner chamber of lamp body 1;Rotary shaft 2 is equipped on heat dissipation module, and rotary shaft 2 is rotatably arranged in through hole 13 and assembly slot 12 along the horizontal direction;Waterproof plug 3 is equipped in assembly slot 12, and waterproof plug 3 and rotary shaft 2 are equipped with waterproof rubber plug 4.

[0022] It can be understood that the upper end of the lamp body 1 is a light outlet, and a tempered glass panel is provided, the lower end of the lamp body 1 is provided with a waterproof cover plate, the waterproof cover plate is provided with a threading interface, the power cord on the light source 11 is led out from the threading interface at the lower end of the lamp body 1, and of course the threading interface has a waterproof function. The utility model can be used for landscape lighting environment on the floor and the pavement, and can be installed on the wall and the ceiling as atmosphere lamp and surface lamp.

[0023] Further, the heat dissipation module is installed in the lamp body 1 by the rotary shaft 2, the rotary shaft 2 passes through the through hole 13 and the assembly slot 12, so that the outer end thereof is exposed to the outer surface of the lamp body 1, the outer end of the rotary shaft 2 is provided with a one-letter port or a cross port, and the light source 11 on the heat dissipation module can be driven by the screwdriver to change the irradiation angle.

[0024] Since the assembly slot 12 and the through hole 13 destroy the airtightness of the inside of the lamp body 1, the utility model preferably sets the waterproof plug 3 and the waterproof rubber plug 4 in the assembly slot 12, the waterproof plug 3 can seal the assembly slot 12, to prevent water vapor from entering the inside of the lamp body 1, and the waterproof rubber plug 4 is filled between the waterproof plug 3 and the rotary shaft 2, the waterproof plug 3 is enhanced by applying elastic pressure, thereby enhancing the sealing property of the waterproof plug 3.

[0025] The inner end of the assembly groove 12 has a limiting groove 14, and the waterproof plug 3 is provided with a positioning ring 31, which passes through the limiting groove 14, thereby forming a horizontal mating connection between the waterproof plug 3 and the assembly groove 12. The outer end of the assembly groove 12 is provided with a sealing opening 15, and the outer end of the waterproof plug 3 is provided with a faceplate 32, which is embedded in the sealing opening 15, thereby forming a horizontal mating connection between the waterproof plug 3 and the assembly groove 12. The limiting groove 14 and the positioning ring 31 cooperate, and the faceplate 32 and the sealing opening 15 cooperate, thereby installing the waterproof plug 3 in the assembly groove 12 of the lamp body 1, preventing the waterproof plug 3 from shifting horizontally. Of course, the faceplate 32 and the positioning ring 31 also improve the sealing effect of the waterproof plug 3.

[0026] The waterproof plug 3 is provided with an actuating groove 33, and the waterproof rubber plug 4 is rotatably inserted into the actuating groove 33. The rotating shaft 2 passes through the waterproof rubber plug 4 and is fixedly connected to it. Both the waterproof rubber plug 4 and the waterproof plug 3 can be made of rubber, and both are elastic, allowing the waterproof rubber plug 4 and the waterproof plug 3 to compress each other to improve the sealing performance. In particular, the waterproof rubber plug 4 is fixedly connected to the rotating shaft 2 so that it rotates synchronously with it, and the waterproof rubber plug 4 can rotate relative to the waterproof plug 3 within the actuating groove 33.

[0027] Furthermore, a gap exists between the outer edge of the waterproof rubber stopper 4 and the actuating groove 33, and the gap is filled with solid grease. Preferably, the outer edge of the waterproof rubber stopper 4 has an angle with the horizontal direction; in simpler terms, the waterproof rubber stopper 4 is a trapezoidal rubber ring. This creates a gap between the waterproof rubber stopper 4 and the waterproof plug 3 for filling with solid grease, reducing friction between the waterproof rubber stopper 4 and the waterproof plug 3, making the adjustment of the rotating shaft 2 more flexible, and preventing the waterproof plug 3 from springing back.

[0028] The heat dissipation module includes a base 21 and a ball-shaped lamp holder 22. The base 21 is fixedly connected to the lamp body 1, and a hemispherical groove 23 is provided on the base 21. The ball-shaped lamp holder 22 is rotatably fitted onto the hemispherical groove 23. The inner end of the rotating shaft 2 is fixedly connected to the ball-shaped lamp holder 22, and the light source 11 is disposed on the ball-shaped lamp holder 22. The ball-shaped lamp holder 22 is adapted to the hemispherical groove 23 on the base 21, so that the ball-shaped lamp holder 22 can rotate relative to the base 21. The ball-shaped lamp holder 22 has a hollow structure, and the light source 11 is installed inside the ball-shaped lamp holder 22. The base 21 and the lamp body 1 are an integral structure, and the heat generated by the light source 11 can be conducted to the lamp body 1 for heat dissipation through the ball-shaped lamp holder 22 and the base 21.

[0029] The base 21 has positioning notches 24 on both sides. A rotating shaft 2 connects to one side of the ball-shaped lamp holder 22 and passes through one of the positioning notches 24. A balancing roller 25 is provided on the other side of the ball-shaped lamp holder 22, rotatably passing through the other positioning notch 24. The balancing roller 25 and the rotating shaft 2 are arranged in the same horizontal direction. The base 21 is integrally formed within the lamp body 1. The positioning notches 24 establish a horizontal axis, allowing the rotating shaft 2 and the balancing roller 25 at both ends of the ball-shaped lamp holder 22 to be coaxially arranged, thus enabling the ball-shaped lamp holder 22 to rotate on the base 21. Preferably, the base 21 has a hemispherical groove 23, allowing the ball-shaped lamp holder 22 to fit snugly against the base 21, and the two can rotate relative to each other. Heat emitted by the light source 11 can be conducted through the ball-shaped lamp holder 22 and the base 21, and dissipated through the lamp body 1.

[0030] This utility model also includes a limiting member 16, which is disposed around the ball-shaped lamp holder 22 inside the upper port of the lamp body 1. The limiting member 16 is fixedly connected to the lamp body 1 and is pressed against the upper surface of the base 21. The upper port of the lamp body 1 is provided with a screw or a bayonet. The aforementioned positioning notch 24 is open. When the ball-shaped lamp holder 22 is assembled on the base 21, the limiting member 16 is inserted into the lamp body 1, and the limiting member 16 covers the positioning notch 24, thereby limiting the rotation shaft 2 and the balancing roller 25.

[0031] The faceplate 32 is provided with an angle nameplate 34, and the outer wall of the lamp body 1 is provided with a scale that matches the angle nameplate 34. When the rotating shaft 2 adjusts the angle, the light source can be precisely adjusted according to the angle nameplate 34 and the scale on the lamp body 1. In particular, when arranging atmosphere and lighting in the same scene, the angle parameters can be set uniformly in advance before installation, which facilitates scene arrangement. Furthermore, the lamp body 1 is provided with several spring pins 17. The present invention adopts a recessed installation. The spring pins 17 are the basic configuration on existing downlights, and existing conventional structures can also be used to achieve quick installation and disassembly.

[0032] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
