[0028] Example 1
[0029] Please see Figure 1-5 An outdoor waterproof filament lamp includes a rain cover 200, which is integrally molded from PC plastic. A ring-shaped rain shield 205 is rotatably mounted on the bottom of the rain cover 200 via a turntable bearing 206. An arc-shaped turbine blade 207 is fixedly connected to the bottom of the rain shield 205. It is important to note that the rotation direction of the turbine blade 207 when driven by wind should be consistent with the threaded locking direction of the rain cover 200 to prevent loosening of the rain cover 200 after prolonged use. An integrally molded mounting head 201 is provided on the top of the rain cover 200. A first contact electrode 203 is fixedly connected to the top edge of the mounting head 201, and a second contact electrode 204 is fixedly connected to the top center of the mounting head 201. The lamp also includes a filament lamp body 500, which is threaded onto the bottom of the mounting head 201 and can be electrically connected to the first contact electrode 203 and the second contact electrode 204 via a wire.
[0030] In implementation, such as Figure 2 and Figure 5 The diagram also includes a lamp holder 100, with a rain cover 200 threadedly installed in a threaded groove 105 at the bottom of the lamp holder 100. The outer surface of the mounting head 201 has an external thread 202 that mates with the threaded groove 105. A circular electrode 103 is fixedly connected to the center of the inner top of the threaded groove 105, and an annular electrode 104 is fixedly connected to the inner top of the threaded groove 105. When the rain cover 200 is installed in the threaded groove 105, the first contact electrode 203 can contact the annular electrode 104 to achieve electrical connection, and the second contact electrode 204 can contact the circular electrode 103 to achieve electrical connection. This method transfers the two electrically connected contact electrodes to the top of the rain cover 200, hiding them at a higher internal position, preventing water immersion and short circuits.
[0031] Specifically, it also includes a power supply wire 400 and an annular intermediate plate 300. The intermediate plate 300 is installed between the lamp holder 100 and the rain cover 200. A rigid insulating tube 301 is connected through the intermediate plate 300. A branch wire 401 is provided inside the power supply wire 400. One end of the branch wire 401 passes through the lower end of the insulating tube 301 and upwards to the opening of the insulating tube 301, and one end of the branch wire 401 is exposed. Two sockets 101 are opened at the bottom of the lamp holder 100. The top of the two sockets 101 is fixedly connected to conductive contact pieces 102, which are electrically connected to the circular electrode 103 and the annular electrode 104, respectively. When the insulating tube 301 is inserted into the socket 101, one end of the branch wire 401 can contact the conductive contact piece 102 and achieve electrical connection.
[0032] This includes an upper rubber ring 302 and a lower rubber ring 304. The upper rubber ring 302 has a through hole 303 for the insulating tube 301 to pass through, and the lower rubber ring 304 has a pre-reserved notch 305 on one side for the installation of the branch wire 401. The upper rubber ring 302 and the lower rubber ring 304 provide elastic pressure to prevent the threaded connection between the rain cover 200 and the lamp holder 100 from loosening, and also provide a sealing and waterproof function.
[0033] Additionally, the inner ring of the turntable bearing 206 is fixedly connected to the inner bottom of the rain cover 200, and the rain shield ring 205 is fixedly connected to the outer ring of the rain cover 200. The cross-section of the rain shield ring 205 is set as an arc-shaped structure or a C-shaped structure. The upper part of the rain shield ring 205 is hidden under the rain cover 200, and the lower part of the rain shield ring 205 extends outward to the outside of the rain cover 200. When the rain shield ring 205 rotates, the rainwater on its surface will be thrown off by centrifugal force, preventing rainwater from splashing downwards from the rain cover 200. It can also provide good rain protection in windy and rainy weather, and it can also provide good waterproofing in windless or light rainy weather.
[0034] Obviously, the embodiments described above are only some embodiments of this application, not all embodiments. The accompanying drawings show preferred embodiments of this application, but do not limit the patent scope of this application. This application can be implemented in many different forms; rather, the purpose of providing these embodiments is to provide a more thorough and comprehensive understanding of the disclosure of this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing specific embodiments, or make equivalent substitutions for some of the technical features. Any equivalent structures made using the content of this application's specification and drawings, directly or indirectly applied to other related technical fields, are similarly within the scope of patent protection of this application.
