[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.
[0024] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," "outer," "lateral," and "longitudinal," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0025] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0026] This application discloses a damping and waterproof connection structure.
[0027] Please refer to Figure 1 and Figure 2A damping and waterproof connection structure includes a first rotating body 1, a second rotating body 2, a damping component, and a waterproof component. The damping component includes a transversely arranged central rotating shaft 3 and a first damping element 4. The first rotating body 1 and the second rotating body 2 are hollow shells, with a first support 5 and a second support 6 protruding from their centers, respectively. The two ends of the central rotating shaft 3 are respectively located within the first support 5 and the second support 6. The first rotating body 1 is rotatably connected to the second rotating body 2 via the central rotating shaft 3. The first damping element 4 is disposed between the first support 5 and the second support 6 and abuts against both supports 5 and 6. When the first rotating body 1 and the second rotating body 2 rotate, the first damping element 4 is compressed and deformed, producing a damping effect. In the actual structure, the first damping element 4 can adopt a ring structure, which can be fitted onto the central rotating shaft 3 for easy installation. The first damping element 4 can also be made of a wear-resistant material, preferably POM material. By utilizing the friction of the first damping element 4, rotational adjustment and locking at any angle can be achieved.
[0028] The right end face of the first rotating body 1 is provided with a first protruding ring 7 near the outer edge of the first rotating body 1, and the left end face of the second rotating body 2 is provided with a second protruding ring 8 near the outer edge of the second rotating body 2, and the diameter of the first protruding ring 7 is smaller than that of the second protruding ring 8. As shown in the figure, the first protruding ring 7 abuts against the left end face of the second rotating body 2, and the second protruding ring 8 abuts against the right end face of the first rotating body 1, so that the first protruding ring 7, the second protruding ring 8, the first rotating body 1 and the second rotating body 2 form an annular groove, and the groove leaves a distance from the first damping member 4 in the longitudinal direction as shown in the figure; the waterproof component includes a first waterproof ring 9, which is disposed in the groove. It can be understood that by setting the second protruding ring 8 of the first protruding ring 7, the connection between the first rotating body 1 and the second rotating body 2 can be sealed, thereby isolating moisture in the air and avoiding damage to the connection structure or circuit structure inside the first rotating body 1 and the second rotating body 2, thus achieving the effect of waterproofing and dustproofing. In the actual structure, the first rotating body 1 and the second rotating body 2 are generally made in one piece. However, due to the precision of the mold, the first rotating body 1 and the second rotating body 2 cannot be completely closed. Therefore, the setting of the first waterproof ring 9 can prevent rainwater from entering the shell through the gap between the first protruding ring 7 and the second protruding ring 8, thus achieving a further waterproof effect.
[0029] In such Figure 1 and Figure 2 In the damping and waterproof connection structure shown, the damping component enables the damping connection between the first rotating body 1 and the second rotating body 2, and the waterproof component enables the waterproof function. The separate setting of the damping component and the waterproof component ensures the waterproof effect of the connection structure while guaranteeing the damping force.
[0030] In one embodiment of this application, the damping assembly may optionally include a connecting bolt 10. As shown in the figure, the left end face of the first rotating body 1 has a right-facing stepped hole 11, and the head of the connecting bolt 10 is engaged in this stepped hole 11. The first rotating body 1, the central rotating shaft 3, and the second rotating body 2 all have mounting holes adapted to the connecting bolt 10, and the screw of the connecting bolt 10 passes through the first rotating body 1 and the central rotating shaft 3 sequentially to connect with the second rotating body 2. Under external force, the connecting bolt 10 can push the first rotating body 1 closer to the second rotating body 2, increasing the deformation of the first damping element 4; or, if the external force is removed, the distance between the first rotating body 1 and the second rotating body 2 returns to its original position, reducing the deformation of the first damping element 4, thereby adjusting the damping force between the first rotating body 1 and the second rotating body 2, and thus obtaining a better damping feel. In a more preferred embodiment based on this, the waterproof assembly may further include a second waterproof ring 12, and the first rotating body 1 has as shown in the figure. Figure 2 The second stepped hole 13 shown is in which the second waterproof ring 12 is disposed. The second stepped hole 13 prevents rainwater or moisture in the air from entering the connection structure through the gap between the connecting bolt 10 and the first rotating body 1, thus preventing corrosion of the connection structure and improving its service life. Furthermore, the first rotating body 1 may be provided with an end cap 14, which can seal the first stepped hole 11 to further improve the waterproof performance of the connection structure.
[0031] In one embodiment of this application, optionally, the first bracket 5 can be completely disposed within the first rotating body 1, while the second bracket 6 protrudes from the second rotating body 2. When the first rotating body 1 is close to the second rotating body 2, the first damping member 4 abuts against the first bracket 5 and the second bracket 6 respectively within the first rotating body 1, so that the first damping member 4 not only maintains a distance from the first waterproof ring 9 in the longitudinal direction as shown in the figure, but also maintains a distance from the first waterproof ring 9 in the transverse direction as shown in the figure, further preventing the damping connection function and the waterproofing function from interfering with each other, and ensuring the independence of the damping connection function and the waterproofing function.
[0032] It should be noted that the damping and waterproof connection structure provided in this application can be applied to any product, equipment or component that needs to rotate relative to each other. More specifically, the first rotating body and the second rotating body can be connected to two components that need to rotate relative to each other, or the two components that need to rotate relative to each other can be integrally formed with the first rotating body and the second rotating body, or the first rotating body and the second rotating body can be set as universal mounting bases or structural bases, and the two components that need to rotate relative to each other can be installed on the first rotating body and the second rotating body, and can be replaced as needed.
[0033] This application also discloses an outdoor lighting fixture.
[0034] Please refer to Figure 3-5 An outdoor lighting fixture includes a lamp body 15, a support column 16, a mounting base 17, and a damping and waterproof connection structure as described above. The lamp body 15 is provided with a first rotating body 1 as described above, and the support column 16 is provided with a second rotating body 2 as described above. The first rotating body 1 and the second rotating body 2 are integrally formed with the lamp body 15 and the support column 16, respectively. The lamp body 15 is rotatably connected to the support column 16 through the damping and waterproof connection structure described above, thereby allowing adjustment of the illumination angle of the outdoor lighting fixture and improving its flexibility.
[0035] The support column 16 includes an obliquely positioned upper end and a vertically positioned lower end. The upper end is used to connect with the second rotating body 2 and the lamp body 15, while the lower end is fixedly connected to a rotating plate 18, which engages within the mounting base 17, allowing the support column 16 to rotate relative to the mounting base 17. Through this arrangement, the lamp body 15 can rotate both horizontally and vertically, further increasing the adjustable range of the lamp body 15's illumination angle and providing greater flexibility for the outdoor lighting fixture. The number of lamp bodies 15 can be set according to actual needs. For example, the outdoor lighting fixture can be as follows: Figure 3 The image shows a double-headed outdoor wall lamp with two lamp bodies.
[0036] In one embodiment of this application, optionally, the mounting base 17 is provided with a mounting groove 20 recessed from the upper end downwards. The mounting groove 20 has a through hole. The lower end of the support column 16 is installed in the mounting groove 20. The rotating piece 18 is engaged with the through hole of the mounting groove 20 within the mounting base 17. The support column 16 is connected to the rotating piece 18 through the through hole in the mounting groove 20. The mounting groove 20 increases the contact area between the support column 16 and the mounting base 17, improving the robustness of the connection between the support column 16 and the mounting base 17.
[0037] The lower surface of the support column 16 has a protruding first step 21. The first step 21 abuts against the side wall of the mounting groove 20 and forms a slot with its bottom wall. A second damping element 22 is provided in this slot. When the support column 16 rotates relative to the mounting base 17, the second damping element 22 is deformed by friction, preventing relative rotation between the support column 16 and the mounting base 17, thereby achieving a damped connection. The second damping element 22 can preferably be a wave-shaped spring. The corrugated spring not only provides resistance when the support column 16 and the mounting base 17 rotate relative to each other, achieving a damped connection between them, but also compensates for any axial gaps between the support column 16 and the mounting groove 20 due to inaccurate installation or material deformation. This ensures that the structure between the support column 16 and the mounting base 17 remains compact, preventing vertical swaying and horizontal swinging, thus increasing the stability of the connection. Furthermore, the corrugated spring distributes load at the connection point, reducing load concentration and further improving product quality and service life.
[0038] The lower surface of the support column 16 is also provided with a protruding second step 23, which is located above the first step 21. A third waterproof ring 24 is provided between the first step 21 and the second step 23 to prevent rainwater from seeping into the support column 16 or the mounting base 17 through the gap between them, thus preventing damage to the connection structure and electronic structure and extending the service life of the lamp. The mounting base 17 can also be equipped with a waterproof plug for the wires to further ensure the waterproof performance of the outdoor lamp.
[0039] In addition, the aforementioned outdoor lighting fixtures may also include functional modules such as power supply boxes, circuit boards for controlling lighting, or wiring terminals. The specific structural methods can adopt common structural methods in the field, and this application does not limit its specifications or the functional embodiments adopted.
[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
