[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0029] Please refer to Figure 1-7 ;

[0030] The strip-shaped underground lamp of the utility model can adjust the illumination angle of the lamp without opening the shell, thereby improving the convenience of adjusting the illumination angle of the underground lamp.

[0031] A strip underground lamp with adjustable angle comprises a shell 1. The shape of the shell 1 can be selected from rectangular parallelepiped, cylindrical and other shapes. The present embodiment preferably adopts a rectangular parallelepiped shape. A light-transmitting top cover 2 is fixedly connected to the shell 1. The light-transmitting top cover 2 can be a fully light-transmitting top cover, or a top cover with shading areas around and light-transmitting only in the middle. The top cover of the present embodiment is light-transmitting only in the middle, which is used to limit the range of light transmission, ensure that the light is focused and is not affected by stray light. A through hole 21 is provided on the light-transmitting top cover 2, and a mounting groove 11 corresponding to the through hole 21 is provided at one end of the shell 1. A bolt 4 is rotatably clamped in the mounting groove 11. In the present embodiment, the nut of the bolt 4 is clamped in the mounting groove 11 to limit the movement of the bolt 4 in the longitudinal, transverse and vertical directions, so that the bolt 4 can only rotate. The screw rod thereof passes downward through the bottom of the mounting groove 11 and is threadedly connected with a lifting screw. The lowering member 5 is provided with a bolt 2 6 on the lifting member 5, the bolt 2 6 is rotatably connected with a connecting member 7, and the connecting member 7 is fixedly connected with a fixing assembly 8. When the lifting member 5 is lifted or lowered, the bolt 2 6 is driven to lift or lower together, and when the bolt 2 6 is lifted or lowered, the connecting member 7 is driven to rotate, and when the connecting member 7 rotates, the fixing assembly 8 rotates with it. A movable hole is provided on the connecting member 7, and the movable hole is elliptical, and its major axis is larger than the diameter of the bolt 2 6, so that the connecting member 7 can rotate, and the minor axis is the same as the diameter of the bolt 2 6, so that the connecting member 7 rotates more smoothly. The fixing assembly 8 extends toward the inside of the shell 1 and is fixedly connected to one end of the lighting assembly 9. The other end of the lighting assembly 9 is rotatably connected to the shell 1, thereby providing a support effect for the lighting assembly 9 to ensure that the fixing assembly 8 rotates smoothly. The lighting assembly 9 corresponds to the light-transmitting top cover 2, and light is emitted from the light-transmitting top cover 2.

[0032] The installation of underground lamps usually requires embedding them underground. The lighting direction of traditional underground lamps must be set before installation. Once buried underground, the lighting angle cannot be changed. However, the utility model overcomes this limitation. Even after the underground burial is completed, the lighting angle of the lamp can still be flexibly adjusted without pre-setting. Specifically, turn on the underground lamp switch, the lighting component 9 is powered on to emit light, and the light is emitted from the light-transmitting top cover 2. Due to the setting of the through hole 21, the operator can directly use a tool to rotate the bolt 4. When the lighting angle needs to be changed, the bolt 4 is rotated using an external tool, such as a screwdriver. By rotating the bolt 4, the lifting member 5 is driven to perform a lifting action, so that the connecting member 7 rotates with it, and the connecting member 7 rotates while driving the fixing component 8 to rotate together. , thereby driving the lighting assembly 9 to rotate together, so as to change the illumination angle of the lighting assembly 9. For example, when the bolt 4 rotates to the right, the lifting member 5 moves upward and drives the fixing assembly 8 to rotate upward, so that the lighting assembly 9 rotates to the right, so the light is emitted to the right. When the bolt 4 rotates to the left, the lifting member 5 moves downward and drives the fixing assembly 8 to rotate downward, so that the lighting assembly 9 rotates to the left, so the light is emitted to the left. The through hole 21 corresponds to the bolt 4, so that the bolt 4 can be directly rotated by a screwdriver. The rotation of the bolt 4 drives the lifting member 5, the connecting member 7, the fixing assembly 8 and the lighting assembly 9 to move together, thereby achieving the effect of conveniently changing the illumination angle of the light without disassembling the transparent top cover 2 and the shell 1.

[0033] In this embodiment, a limiting groove 12 and a boss are correspondingly provided at the end of the shell 1, and the bolt 2 6 is placed in the limiting groove 12. The end of the screw 2 passes through the lifting member 5 and extends into the limiting groove 12. The limiting groove 12 limits the lifting height of the lifting member 5. The boss 13 is located below the lifting member 5. By arranging the boss below the lifting member 5, it is prevented that the bolt 1 4 rotates too many times, which causes the lifting member 5 to descend too far and separate from the bolt 1 4.

[0034] In this embodiment, a through hole 14 is provided at one end of the shell 1, and a fixing seat 15 is provided at the outer edge of the through hole 14. A fixing block 151 is provided on the fixing seat 15. A C-shaped notch 152 for limiting the rotation angle of the connecting member 7 is provided between the fixing seat 15 and the fixing block 151, and its opening angle is 100°. The fixing block 151 is used to fix the connecting member 7 in the C-shaped groove to prevent the connecting member 7 from falling off.

[0035] Specifically, with the direction toward the lifting member 5 as the standard of 0°, when the connecting member 7 is rotated upward to an angle of 50°, its upper side wall will abut against the upper side wall of the opening of the C-shaped groove, and it will not be able to continue to rotate upward. When the connecting member 7 is rotated downward to an angle of 50°, its lower side wall will abut against the lower side wall of the opening of the C-shaped groove, and it will not be able to continue to rotate downward, thereby achieving the purpose of limiting the rotation angle of the connecting member 7.

[0036] In this embodiment, the fixing assembly 8 includes a fixing member 85 , on which a rotating rod 81 is provided. An extension portion 82 is provided at the end of the rotating rod 81 , and the extension portion 82 passes through the second through hole 14 and interlocks with the connecting member 7 .

[0037] Specifically, the rotating rod 81 passes through the through hole 14 and abuts against the side wall of the through hole 14, thereby supporting the fixing member 85. The extension portion 82 is interlocked with the connecting member 7. The interlocking structure, for example, the extension portion 82 structure adopts an elliptical cylinder, a cube, a rectangular parallelepiped, etc. to form an interlocking structural shape design, and the end of the connecting member 7 connected to the extension portion 82 is designed as a locking hole corresponding to the shape, ensuring that the rotating rod 81 rotates with the connecting member 7.

[0038] In this embodiment, a groove 83 centered on the rotating rod 81 is provided on the fixing member 85, and a C-shaped protrusion 84 with an opening angle of 100° is provided on the outer edge of the groove 83. A boss 2 16 rotatably connected to the groove 83 is provided on the inner side of the shell 1 with the through hole 2 14 as the center, and a boss 3 17 for limiting the rotation angle of the protrusion is provided on one side of the boss 2 16.

[0039] Specifically, the groove 83 is rotatably connected to the boss 2 16 to reduce the gravity borne by the rotating rod 81 and improve the service life of the rotating rod 81. The opening angle of the protrusion is 100 degrees, and the boss 3 17 is arranged in the opening direction of the protrusion. When the protrusion is rotated to a certain angle, its opening side wall abuts against the boss 3 17, thereby achieving the purpose of limiting the rotation angle of the fixing member 85.

[0040] In this embodiment, the lighting assembly 9 includes a base 91, the base 91 is provided with a slot 92, the slot 92 is clamped with a PCB board 93, and a plurality of lamp beads 94 are arranged in sequence on the PCB board 93 to ensure stable lighting.

[0041] In addition, the base 91 is a heat dissipation base made of aluminum. Aluminum has the advantages of light weight and low cost. The PCB is installed in the base 91. The lower end of the base 91 is provided with heat dissipation fins 95 to help the PCB dissipate heat when working and prevent the PCB board 93 from operating at too high a temperature, reducing its service life.

[0042] In this embodiment, the light-transmitting top cover 2 includes a light guide plate 22, and light penetrates to the outside through the light guide plate 22. A slot 18 for installing the light guide plate 22 is provided on the top of the shell 1. The slot 18 is provided with at least two seals 201. The outer periphery of the light guide plate 22 extends outward into the slot 18 and abuts against the seal 201. The seal 201 ensures that the underground lamp has a good sealing structure, which can effectively prevent dust, water, etc. from entering the interior of the shell 1, thereby improving the service life of the underground lamp. In this embodiment, the seal 201 is arranged at the upper and lower ends of the slot 18. Since the seal 201 is made of a flexible material, such as rubber, the characteristics of the flexible material ensure that the light guide plate 22 is tightly and seamlessly connected to the seal 201, thereby improving the stability and service life of the entire underground lamp. Three seals 201 can also be used, which are respectively arranged at the upper and lower ends and the side walls of the slot 18 to achieve the best sealing effect.

[0043] In this embodiment, the outer side of the shell 1 is fixedly connected to the buried shell 3 through the support frame 19, and the top of the buried shell 3 is abutted against the light-transmitting top cover 2. Since the buried lamp is a lamp used to be embedded in the ground and provide lighting function, the buried shell 3 is arranged on the outer periphery of the shell 1 to ensure that the buried lamp still has the function of adjusting the lighting angle when embedded in the ground.

[0044] In this embodiment, air inlets 31 are provided on both sides of the underground shell 3, and dustproof nets 33 are provided on the inner side of the air inlet 31 to prevent dust, impurities and other particles from flowing in with the air, which not only ensures the cleanliness of the equipment operating environment, but also extends the service life of the underground lamp. An air inlet 2 32 is provided at the bottom of the shell 1. Specifically, air can enter the underground shell 3 from the air inlet 31, and then enter the shell 1 from the air inlet 2 32, which is beneficial to the heat dissipation and ventilation inside the shell 1, and ensures the long-term stable operation of the underground lamp.
