[0033] In the description of the present utility model, it should be understood that the terms "first", "second", etc. are used in the present utility model to describe various information, but these information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present utility model, the "first" information may also be referred to as the "second" information, and similarly, the "second" information may also be referred to as the "first" information.
[0034] As Figures 1 to 6 shown, an embodiment of the present utility model provides a downlight 100, which includes a base 10, a light-emitting module 20 and a power cord 30. The base 10 is recessed downward to form a movable groove 11; the light-emitting module 20 includes a light-emitting base 21, a light-emitting plate 22 and a light-emitting cover 23. The light-emitting base 21 is movably disposed in the movable groove 11, the light-emitting plate 22 is fixedly disposed in the light-emitting base 21, and the light-emitting cover 23 is disposed on the top of the light-emitting base 21; the power cord 30 passes through the base 10 and the light-emitting base 21 and is connected to the light-emitting plate 22. A threaded post 40 is fixedly sleeved on the outer periphery of the power cord 30, and the threaded post 40 passes through between the light-emitting base 21 and the base 10; wherein, a first nut 50 threadedly connected to the threaded post 40 is disposed on the outer wall of the base 10, and a second nut 60 threadedly connected to the threaded post 40 is disposed on the inner wall of the light-emitting base 21.
[0035] Based on the above technical solution, in this embodiment, a first nut 50 is provided on the outer wall of the base 10 and a second nut 60 is provided on the inner wall of the light-emitting base 21. Through the double-nut locking structure, the power cord 30 is locked from both the inside and outside of the downlight 100, thereby firmly locking the power cord 30. When it is necessary to adjust the light-emitting angle of the light-emitting module 20, first remove the light-emitting cover 23 on the top of the light-emitting base 21, then loosen the first nut 50 and the second nut 60, and rotate the light-emitting base 21 around the threaded post 40 to an appropriate angle, and then tighten the first nut 50 and the second nut 60 again to lock the threaded post 40 and the base 10, and finally cover the light-emitting cover 23, thereby adjusting the light-emitting angle of the light-emitting module 20.
[0036] As Figure 6 shown, after the light-emitting module 20 is rotated, its light-emitting angle can be adjusted.
[0037] In this embodiment, the first nut 50 is provided on the outer wall of the base 10 to lock the power cord 30 from the outside; the second nut 60 is provided on the inner wall of the light-emitting base 21 to further lock the power cord 30 from the inside. This embodiment improves the stability of the power cord 30 through the double-nut locking structure and avoids loosening of the power cord 30 during use.
[0038] As an implementation manner, as Figure 5 shown, a first washer 70 is provided between the first nut 50 and the outer wall of the base 10, and the first washer 70 is sleeved on the threaded post 40.
[0039] Specifically, when the first nut 50 is tightened, the pressure generated by it will be evenly distributed on the outer wall of the base 10 through the first washer 70, which helps to reduce the risk of damage to the base 10 or the threaded post 40 caused by excessive local pressure. On the other hand, the first washer 70 can enhance the sealing performance between the first nut 50 and the base 10. During the use of the downlight 100, especially when the downlight 100 is installed in a humid or dusty environment, the first washer 70 can prevent impurities such as moisture and dust from entering the inside of the base 10, protect the internal circuit and components from damage, and extend the service life.
[0040] In this embodiment, the first washer 70 is usually made of wear-resistant materials such as rubber, plastic or metal. During the process of the first nut 50 directly contacting and repeatedly tightening and loosening the base 10, the first washer 70 plays a buffering and lubricating role, reducing the direct friction and wear between the two.
[0041] As an implementation manner, as Figure 5 shown, a second washer 80 is provided between the second nut 60 and the light-emitting base 21, and the second washer 80 is sleeved on the threaded post 40.
[0042] In this embodiment, similar to the first washer 70, the second washer 80 also plays a role in reducing wear and damage. During the frequent rotation and angle adjustment of the light-emitting base 21, the direct contact between the second nut 60 and the light-emitting base 21 will cause friction and wear. As an intermediate buffer layer, the second washer 80 can protect the surface of the light-emitting base 21 from being damaged.
[0043] On the other hand, when the second nut 60 is tightened, the second washer 80 can ensure that the contact between the second nut 60 and the light-emitting base 21 is more uniform and tight, enhancing the stability of the connection.
[0044] As an implementation manner, as Figure 2 shown, the side wall of the base 10 is provided with a first through hole 12, and the side wall of the light-emitting base 21 is provided with a second through hole 24 corresponding to the first through hole 12. The threaded column 40 is fixedly connected to the second through hole 24, and the threaded column 40 is rotatably connected to the first through hole 12.
[0045] Specifically, by fixedly connecting the threaded column 40 to the second through hole 24, the threaded column 40 is fixedly connected to the light-emitting base 21; by rotatably connecting the threaded column 40 to the first through hole 12, the threaded column 40 can rotate around the first through hole 12, so that the light-emitting base 21 can be rotated and adjusted relative to the base 10. When the light-emitting angle needs to be adjusted, the light-emitting base 21 is rotated to an appropriate angle, and the light-emitting base 21 and the threaded column 40 rotate around the first through hole 12 as the rotation center, thereby adjusting the light-emitting angle of the light-emitting module 20.
[0046] As an implementation manner, as Figure 2 shown, the power cord 30 includes a core layer 31 and a braided layer 32. The braided layer 32 is sleeved on the outer periphery of the core layer 31, and the threaded column 40 is sleeved on the outer periphery of the braided layer 32.
[0047] Specifically, the braided layer 32 is sleeved on the outer periphery of the core layer 31, providing mechanical protection and support for the core layer 31. The braided layer 32 is usually formed by intertwining multiple thin wires, having high tensile strength and wear resistance, and can prevent the core layer 31 from being damaged due to external forces, such as being pulled, twisted or cut. The braided layer 32 not only enhances the physical strength of the power cord, but also plays a certain electromagnetic shielding role, which can reduce the electromagnetic interference around the power cord and protect the internal transmitted signal or current from being affected by the external electromagnetic field. The core layer 31 is used to transmit electric energy, which is usually made of a conductive material (such as copper, aluminum, etc.) and has good electrical conductivity, ensuring the smooth transmission of current in the power cord and meeting the power supply requirements of the device.
[0048] As an implementation manner, as Figure 4 and Figure 5As shown, a limiting ring 33 is provided at one end of the braided layer 32 close to the light-emitting cover 23. There is a gap between the limiting ring 33 and the threaded post 40, and a sealing ring 90 is provided in the gap. The sealing ring 90 is sleeved on the threaded post 40.
[0049] Specifically, the sealing ring 90 is usually made of an elastic material and has good sealing performance and compression deformation ability. In this embodiment, the sealing ring 90 is arranged between the limiting ring 33 and the threaded post 40. When the threaded post 40 passes through the gap and is in close contact with the sealing ring 90, the sealing ring 90 fills the gap due to its own elasticity and compression deformation, forming a reliable sealing barrier to prevent water, dust, gas or other media from penetrating into the interior of the light-emitting base 21 from this part.
[0050] As an implementation manner, the limiting ring 33 is integrally formed with the braided layer 32, and the diameter of the limiting ring 33 is larger than the diameter of the second through hole 24.
[0051] Specifically, the diameter of the limiting ring 33 is larger than the diameter of the second through hole 24, so that after the power cord 30 passes through the through hole and is installed in place, an effective clamping effect can be formed to prevent the power cord 30 from loosening or falling off.
[0052] As an implementation manner, as Figure 2 and Figure 5 shown, an annular cover 25 is provided at the opening of the light-emitting base 21. The edge of the light-emitting cover 23 is snap-fitted with the inner wall of the annular cover 25, and the outer wall of the annular cover 25 is threadedly connected to the inner wall of the light-emitting base 21; wherein, an annular groove 26 is provided at the opening edge of the light-emitting base 21, and a rubber ring 27 is sleeved in the annular groove 26. The rubber ring 27 abuts between the light-emitting base 21 and the annular cover 25.
[0053] Specifically, in this embodiment, the light-emitting base 21, the light-emitting cover 23 and the annular cover 25 are installed by combining snap-fitting connection and threaded connection, ensuring the tight connection between the light-emitting cover 23 and the light-emitting base 21. At the same time, an annular groove 26 is provided at the opening edge of the light-emitting base 21 and a rubber ring 27 is sleeved, forming a sealing structure to prevent external media such as water and dust from entering the interior of the light-emitting base 21 and protecting the light-emitting component 20 and the circuit from damage.
[0054] As an implementation manner, as Figure 2 shown, the threaded post 40 is provided with a limiting plane, and the second through hole 24 is provided with a planar portion 28. The limiting plane abuts against the planar portion 28 to fixedly connect the threaded post 40 and the second through hole 24.
[0055] Specifically, the threaded post 40 is inserted through the second through hole 24. The limiting plane of the threaded post 40 abuts against the flat portion 28 of the second through hole 24, so as to realize the fixed connection between the threaded post 40 and the second through hole 24, and further realize the fixed connection between the threaded post 40 and the light-emitting base 21. In this way, it can rotate with the first through hole 12 as the rotation center to adjust the light-emitting angle of the light-emitting base 21.
[0056] As an implementation manner, as Figure 2 and Figure 5 shown, the base 10 bends and extends gradually away from the light-emitting cover 23 from the opening edge of the light-emitting base 21 to the center of the light-emitting base 21, so as to form a recessed activity groove 11 by depression. The shape of the light-emitting base 21 is adapted to the activity groove 11.
[0057] Exemplarily, the shapes of the light-emitting base 21 and the activity groove 11 are both bowl-shaped structures similar to semi-circular shapes, so that the light-emitting base 21 can rotate in the activity groove 11 to adjust the light-emitting angle.
[0058] As an implementation manner, as Figure 1 and Figure 2 shown, the downlight 100 further includes a heat dissipation base 101 and a spring buckle 102. The base 10 is arranged in the heat dissipation base 101. The heat dissipation base 101 is used to dissipate the heat generated by the base 10 and the light-emitting module 20 during operation, so as to improve the heat dissipation capacity of the downlight 100. The two spring buckles 102 are respectively arranged on both sides of the heat dissipation base 101 and are used for the installation and fixation of the downlight 100.
[0059] It should be understood that the term "and / or" used in the specification and appended claims of the present invention refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations. It should be noted that in this article, the term "comprises", "comprising" or any other variation thereof is intended to cover a non-exclusive inclusion, so that a process, method, article or system including a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or system.
