Description

Technical Field

[0001] This application relates to the technical field of lighting fixtures, and in particular to a high-mast lighting fixture. Background Technology

[0002] High-mast lighting fixtures generally refer to a new type of lighting device consisting of steel light poles over 10 meters high and high-power combined light frames. It consists of a lamp head, a pole body, and a foundation.

[0003] High-mast lighting fixtures are generally used outdoors, where there is a lot of dust. Existing fixtures consist of two housings with a sealing ring and a lamp panel installed between them. The sealing ring surrounds the lamp panel, sealing the gap between the two housings to prevent dust from accumulating on the lamp panel. However, the contact between the sealing ring and the two housings is point-to-point. Dust travels a short distance through the gap between the sealing ring and the housings, resulting in poor sealing. Consequently, dust can easily bypass the sealing ring and adhere to the lamp panel, affecting its lighting performance. This needs improvement. Utility Model Content

[0004] The purpose of this application is to provide a high-mast lighting fixture to improve the sealing effect.

[0005] This application provides a high-mast lighting fixture with the following technical solution: It includes a pole body, a mounting base connected to the top of the pole body, a connecting housing connected to the mounting base, a transparent housing connected to the connecting housing, a sealing ring and a lamp plate connected between the connecting housing and the transparent housing, the sealing ring surrounding the lamp plate, and both the connecting housing and the transparent housing having annular grooves for engaging with the sealing ring. The sealing ring has two opposing planes, each abutting against the bottom wall of one of the two annular grooves. The sealing ring also has two abutting structures, each corresponding to one of the annular grooves and abutting against the inner wall of the annular groove.

[0006] By adopting the above technical solution, the flat surface abuts against the bottom wall of the annular groove, increasing the contact area between the sealing ring and the connecting housing, as well as between the sealing ring and the transparent housing. This increases the path for dust to pass between the sealing ring and the connecting housing, or between the sealing ring and the transparent housing, thereby improving the sealing effect, reducing dust adhesion to the lamp panel, and ensuring the lighting effect. The abutting structure also abuts against the inner wall of the annular groove, thus improving the stability of the sealing ring installed within the annular groove.

[0007] Optionally, the clamping structure includes an elastic portion disposed on the sealing ring, the elastic portion being annular and inclined relative to the sealing ring, the elastic portion being located between the two planes.

[0008] By adopting the above technical solution, when the elastic part is inserted into the annular groove, the inner wall of the annular groove abuts against the elastic part. The elastic part is compressed and undergoes elastic deformation and maintains the tendency of elastic reset. The elastic part applies force to the inner wall of the annular groove, and the elastic part abuts against the inner wall of the annular groove. This can not only improve the stability of the sealing ring installed in the annular groove, but also reduce the gap between the inner wall of the annular groove and the elastic part through which dust passes, thereby improving the sealing effect.

[0009] Optionally, the elastic portion is provided with an inclined surface, and the distance between the inclined surface and the sealing ring gradually decreases in the direction away from the other abutting structure.

[0010] By adopting the above technical solution, when the elastic part is inserted into the ring groove, the inner wall of the ring groove abuts against the inclined surface and drives the end of the inclined surface away from the sealing ring to slide towards the sealing ring. The inclined surface plays a guiding role in the installation of the sealing ring, so that the elastic part can be inserted into the ring groove more smoothly.

[0011] Optionally, the clamping structure has two elastic parts, the sealing ring is located between the two elastic parts, the annular groove has two sidewalls, and the farthest distance between the two elastic parts is greater than the distance between the two sidewalls.

[0012] By adopting the above technical solution, when the elastic part is inserted into the annular groove, the elastic part is compressed and undergoes elastic deformation and maintains the tendency to elastically return to its original position. The two elastic parts abut against the two side walls of the annular groove respectively, which increases the contact area between the elastic part and the side walls, increases the movement path of dust, and improves the sealing effect.

[0013] Optionally, the sealing ring is provided with two growing portions, and the two planes are respectively provided on the side of the two growing portions away from the sealing ring. The width of the plane is greater than the width of the sealing ring, and the width of the plane is less than the farthest distance between the two elastic portions.

[0014] By adopting the above technical solution, the width of the growth section is made to be greater than the width of the sealing ring, which can increase the contact area between the sealing ring and the bottom wall of the ring groove and enhance the sealing effect; the width of the growth section is less than the farthest distance between the two elastic sections, which can ensure that the elastic sections are pressed against the inner wall of the ring groove to achieve a seal, further improving the overall sealing performance and better preventing dust from entering and affecting the lighting effect of the lamp panel.

[0015] Optionally, each of the planes is provided with a protrusion, the protrusion being annular, and the bottom wall of the annular groove is provided with a groove for engaging with the protrusion, the groove communicating with the annular groove.

[0016] By adopting the above technical solution, when the sealing ring is inserted into the annular groove, the protrusion is inserted into the groove, and the outer surface of the protrusion fits against the inner wall of the groove, which increases the contact area between the inner wall of the annular groove and the plane, increases the movement path of dust, and thus reduces the amount of dust entering and adhering to the lamp plate.

[0017] Optionally, there are four protrusions, one plane corresponds to two protrusions, the two protrusions are spaced apart, the number of grooves is equal to the number of protrusions, and the grooves correspond one-to-one with the protrusions.

[0018] By adopting the above technical solution, multiple protrusions increase the contact area between the inner wall of the annular groove and the flat surface, increasing the movement path of dust and thus reducing the amount of dust entering and adhering to the lamp panel. Even if one protrusion is damaged and loses its sealing effect, another protrusion can still provide a seal, ensuring a reliable seal.

[0019] Optionally, the connecting housing is provided with a positioning groove for cooperating with the lamp panel. The lamp panel is connected to a plurality of first fixing members, and the lamp panel is fixedly connected to the connecting housing through the first fixing members.

[0020] By adopting the above technical solution, the lamp panel is inserted into the positioning groove, and the outer surface of the lamp panel fits against the inner wall of the positioning groove. The positioning groove plays a positioning role in the installation of the lamp panel, so that the lamp panel is accurately installed on the connecting housing. Using the first fastener to fix the lamp panel to the connecting housing makes the lamp panel installed on the connecting housing more securely.

[0021] Optionally, the connecting housing is provided with at least two positioning posts, and the transparent housing is provided with positioning holes corresponding to the positioning posts. The positioning holes are used to cooperate with the positioning posts. The connecting housing is connected with a plurality of second fixing members, and the connecting housing is fixedly connected to the transparent housing through the second fixing members.

[0022] By adopting the above technical solution, when the transparent shell is installed on the connecting shell, the positioning pin engages with the positioning hole, and the outer surface of the positioning pin fits against the inner wall of the positioning hole. The positioning pin restricts the horizontal movement of the transparent shell, ensuring that the transparent shell is accurately installed on the connecting shell. Using a second fastener to securely connect the transparent shell to the connecting shell makes the transparent shell more stable when installed on the connecting shell.

[0023] Optionally, the end of the positioning post away from the connecting housing is arc-shaped.

[0024] By adopting the above technical solution, the arc-shaped positioning post plays a guiding role in the installation of the transparent shell, thereby improving the efficiency of installing the transparent shell on the connecting shell.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. The plane and the bottom wall of the annular groove are tightly pressed together, which increases the contact area between the sealing ring and the connecting housing and between the sealing ring and the transparent housing, that is, increases the path of dust through the sealing ring and the connecting housing or between the sealing ring and the transparent housing, thereby improving the sealing effect, reducing dust adhesion to the lamp panel, and ensuring the lighting effect.

[0026] 2. When the elastic part is inserted into the ring groove, the inner wall of the ring groove abuts against the elastic part. The elastic part is compressed and undergoes elastic deformation and maintains the tendency to elastically return to its original position. The elastic part applies force to the inner wall of the ring groove, and the elastic part and the inner wall of the ring groove are pressed tightly together. This can improve the stability of the sealing ring installed in the ring groove, and reduce the gap between the inner wall of the ring groove and the elastic part through which dust passes, thereby improving the sealing effect.

[0037] The following is in conjunction with the appendix Figure 1 -Appendix Figure 9 This application will be described in further detail.

[0038] This application discloses a high-mast lighting fixture.

[0039] Combination Figure 1 , Figure 2 and Figure 3 As shown, the device includes a cylindrical rod 1. A mounting base 2 is fixedly connected to the top of the rod 1. The mounting base 2 includes a mounting ring 21 and a connecting part 22 fixedly connected to the mounting ring 21. The mounting ring 21 is sleeved on the rod 1 and fixedly connected to the rod 1. A connecting housing 3 is fixedly connected to the end of the connecting part 22 away from the mounting ring 21. The connecting housing 3 is plate-shaped. A transparent housing 4 and a lamp plate 5 are connected to the side of the connecting housing 3 away from the connecting part 22. A positioning groove 31 is provided on the side of the connecting housing 3 away from the connecting part 22. The lamp plate 5 is inserted into and cooperates with the positioning groove 31. Several first fixing members 51 are connected to the lamp plate 5. The first fixing members 51 are bolts. In this embodiment, there are four first fixing members 51, which are located at the four corners of the lamp plate 5. Each first fixing member 51 passes through the lamp plate 5 and is threadedly connected to the connecting housing 3.

[0040] Combination Figure 3 and Figure 4 As shown, the transparent housing 4 covers the lamp panel 5. At least two positioning posts 32 are provided on the side of the connecting housing 3 near the transparent housing 4. The positioning posts 32 are integrally formed with the transparent housing 4. In this embodiment, for example, there are two positioning posts 32, spaced apart, with the end of each positioning post 32 away from the connecting housing 3 being arc-shaped. The transparent housing 4 has positioning holes 41 corresponding to the positioning posts 32, allowing the positioning posts 32 to engage with and cooperate with the positioning holes 41. The connecting housing 3 is connected to several second fixing members 33, which are bolts. In this embodiment, for example, there are four second fixing members 33, located at the four corners of the connecting housing 3. The second fixing members 33 pass through the connecting housing 3 and are threadedly connected to the transparent housing 4.

[0041] Combination Figure 5, Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, a sealing ring 6 connects the transparent housing 4 and the connecting housing 3. The sealing ring 6 is annular and surrounds the lamp plate 5. Annular grooves 34 are formed on opposite sides of both the connecting housing 3 and the transparent housing 4, surrounding the lamp plate 5. The sealing ring 6 is inserted into and mates with the annular grooves 34. Two extension portions 61 are arranged opposite each other on the sealing ring 6, with the sealing ring 6 located between the two extension portions 61. The extension portions 61 are integrally formed with the sealing ring 6 and are annular in shape. A flat surface 62 is formed on the side of each extension portion 61 away from the sealing ring 6. When the extension portion 61 is installed in the annular groove 34, the flat surface 62 is in contact with and abuts against the bottom wall of the annular groove 34. The width of the flat surface 62 is D1, and the width of the sealing ring 6 is D2. The width of the flat surface 62 is greater than the width of the sealing ring 6. Each plane 62 has two protrusions 63 opposite to each other. The protrusions 63 are integrally formed with the growth part 61. The protrusions 63 are annular and spaced apart. The end of the protrusion 63 away from the growth part 61 is arc-shaped. The bottom wall of the annular groove 34 has grooves 35 that correspond one-to-one with the protrusions 63. The grooves 35 are connected to the annular groove 34. The protrusions 63 are inserted into the grooves 35 and cooperate with the grooves 35.

[0042] Combination Figure 7 , Figure 8 and Figure 9 As shown, the sealing ring 6 is provided with two abutting structures 64, which are located between two growing portions 61. Each abutting structure 64 corresponds to and is located within an annular groove 34. Each abutting structure 64 includes two elastic portions 641 disposed opposite to each other on the sealing ring 6. The elastic portions 641 are integrally formed with the sealing ring 6, and the sealing ring 6 is located between the two elastic portions 641. The elastic portions 641 are annular in shape. The elastic portions 641 are inclined relative to the sealing ring 6, and each elastic portion 641 has an inclined surface 6411. The distance between the inclined surface 6411 and the sealing ring 6 gradually increases in the direction away from the corresponding growing portion 61. The farthest distance between the two elastic portions 641 is D3. The annular groove 34 has two sidewalls, and the distance between the two sidewalls is D4, where D3 is greater than D4.

[0043] The implementation principle of a high-mast lighting fixture according to an embodiment of this application is as follows: the plane 62 abuts against the bottom wall of the annular groove 34, increasing the contact area between the sealing ring 6 and the connecting housing 3, and between the sealing ring 6 and the transparent housing 4. This increases the path for dust to pass through the sealing ring 6 and the connecting housing 3, or between the sealing ring 6 and the transparent housing 4, thereby improving the sealing effect, reducing dust adhesion to the lamp plate 5, and ensuring the lighting effect. When the elastic part 641 is inserted into the annular groove 34, the inner wall of the annular groove 34 abuts against the elastic part 641. The elastic part 641 is compressed and undergoes elastic deformation, maintaining a tendency to elastically return to its original position. The elastic part 641 applies force to the inner wall of the annular groove 34, and the elastic part 641 abuts against the inner wall of the annular groove 34. This not only improves the stability of the sealing ring 6 installed in the annular groove 34, but also reduces the gap between the inner wall of the annular groove 34 and the elastic part 641, thus improving the sealing effect.

[0044] 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.
