Description

Technical Field

[0001] This utility model belongs to the field of lighting technology, and particularly relates to a rotating sealing structure for a lamp cover, a lighting fixture, and a solar street light. Background Technology

[0002] Streetlights, as a crucial component of urban infrastructure, are vital for ensuring nighttime illumination and public safety. In existing streetlight designs, the electrical enclosure, as the core area housing key components such as the power supply, directly impacts the reliability and lifespan of the streetlight due to its structural design and sealing performance. Typically, the electrical enclosure consists of a base and a top cover that rotate to close, adapting to lighting needs in various environments, including severe weather conditions such as heavy rain, heavy snow, and hail.

[0003] To prevent water ingress from affecting the normal operation of internal components, a sealing structure is specially designed at the junction of the base and the top cover. Specifically, the base has an annular protrusion, and the top cover has a corresponding annular groove, within which a sealing ring is placed. During the closing process, the annular protrusion compresses the sealing ring, thereby forming a waterproof seal to prevent the intrusion of external moisture.

[0004] However, traditional electrical cavity sealing structures have significant drawbacks in terms of rotational connection. In current designs, the base is rotatably connected to the top cover via only one pivot. This single-point-of-rotation structure is prone to causing a series of problems during the closing operation. In particular, during the closing process, the sealing ring closer to the pivot will first come into contact with and be compressed by the annular protrusion on the base. Due to this uneven force contact method, the sealing ring is prone to displacement or shifting, resulting in unstable sealing performance.

[0005] Further analysis revealed that because some of the sealing rings initially contacted and were compressed by the annular protrusions, during the subsequent closing process, the protrusions that made initial contact continued to exert a force on the sealing ring towards the rotating shaft. This continuous compressive force forced the sealing ring to move towards the rotating shaft, resulting in a reduced fit between the other side of the sealing ring and the annular groove. This insufficient fit directly led to a decrease in the sealing effect, making the electrical cavity more susceptible to moisture intrusion under harsh weather conditions, increasing the risk of damage to internal components, and affecting the overall performance and reliability of the streetlight. Utility Model Content

[0006] To address the aforementioned problems, the purpose of this utility model is to provide a rotating sealing structure for a lamp cover, a lamp fixture, and a solar street light. This rotating sealing structure ensures that the elastic sealing element does not shift when it is squeezed and sealed, thereby guaranteeing the sealing effect.

[0007] To achieve the above objectives, the technical solution of this utility model is as follows:

[0008] A rotating sealing structure for a lamp cover is used for the rotating connection between the lamp cover and the base and for sealing the electrical cavity on the base, including a rotating connector, a fixing component and an elastic compression sealing component;

[0009] The two ends of the rotating connector are respectively rotatably connected to the lamp cover and the base. The lamp cover can be rotated relative to the base and rotated and translated relative to the base through the rotating connector, so that the lamp cover can be translated parallel to the base and cover it.

[0010] The elastic compression sealing assembly is disposed between the lamp cover and the base and surrounds the electrical cavity. The elastic compression sealing assembly includes an elastic seal and is configured to seal the electrical cavity by compressing the elastic seal when the lamp cover is closed on the base.

[0011] The fixing component is used to fix the lamp cover to the base when the lamp cover is closed on the base, and the elastic compression sealing component compresses the elastic seal through the fixing force of the fixing component.

[0012] According to one embodiment of the present invention, the elastic compression sealing assembly includes an annular protrusion and an annular sealing groove, one of the annular protrusion and the annular sealing groove being disposed on the lamp cover and the other being disposed on the base, and the elastic sealing element being disposed in the annular sealing groove;

[0013] The annular protrusion and the annular sealing groove are arranged opposite to each other. When the lamp cover is closed on the base, the annular protrusion extends into the annular sealing groove and squeezes the elastic sealing element. The elastic sealing element deforms elastically and cooperates with the groove wall of the annular sealing groove to achieve a seal.

[0014] According to one embodiment of the present invention, the elastic seal has a slot at one end facing the annular protrusion, and when the annular protrusion extends into the annular sealing groove, it is inserted into the slot to compress the elastic seal.

[0015] According to one embodiment of the present utility model, the base and the lamp cover are respectively provided with a first limiting member and a second limiting member on both sides of the rotating connector;

[0016] The first limiting member is used to limit the rotating connector after the lamp cover is rotated open, thereby restricting the rotating connector from rotating in the rotation opening direction;

[0017] The second limiting member is used to limit the lamp cover after it is rotated open, thereby restricting the lamp cover from rotating in the rotational opening direction.

[0018] According to one embodiment of the present invention, the first limiting member and the second limiting member are respectively located at both ends of the rotating connector; and the first limiting member is located on the side of the rotating connector facing the rotational opening direction, and the second limiting member is located on the side of the rotating connector facing the rotational closing direction.

[0019] According to an embodiment of the present utility model, the first limiting member is provided with a limiting inclined surface, and the limiting inclined surface is inclined in a direction away from the rotating connecting member and inclined upward.

[0020] After the lamp cover is rotated open, the rotating connector abuts against the limiting inclined surface by the weight of the lamp cover and the rotating connector.

[0021] According to one embodiment of the present utility model, the lamp cover is provided with a mounting component, the rotating connecting component is rotatably connected to the mounting component, and the second limiting component is provided on the mounting component.

[0022] According to one embodiment of the present invention, there are two rotating connecting members, which are respectively located on both sides of the base.

[0023] According to one embodiment of the present invention, the fixing component includes a plurality of buckles, which are disposed on one of the lamp cover and the base, and engage with the other of the lamp cover and the base when the lamp cover is closed on the base.

[0024] According to one embodiment of the present invention, the rotating connector is disposed at one end of the base and / or the lamp cover.

[0025] Based on the same concept, this utility model also provides a lamp, including the lamp cover rotation sealing structure described in any of the above embodiments.

[0026] Based on the same concept, this utility model also provides a solar street light, including the lamp cover rotation sealing structure described in any of the above embodiments, wherein the lamp cover is a photovoltaic panel.

[0027] Because of the adoption of the above technical solution, this utility model has the following advantages and positive effects compared with the prior art:

[0028] 1. In this utility model, the two ends of the rotating connector are rotatably connected to the lamp cover and the base, respectively. This unique structural design allows the lamp cover to rotate and open relative to the base via the rotating connector, enabling the base to flexibly switch between open and closed states. Crucially, the rotatable connection between the lamp cover and the head end of the rotating connector, and between the base and the tail end of the rotating connector, ensures that when the lamp cover rotates towards the base to close, it can close parallel to the base and the elastic seal. This action characteristic allows the lamp cover to simultaneously and evenly contact and compress all parts of the elastic seal, ensuring balanced force on the elastic seal and effectively preventing displacement due to uneven force. This eliminates local seal failure, significantly improves overall sealing performance, provides reliable protection for internal components of the lamp, extends the lamp's lifespan, and reduces component damage and repair costs caused by sealing problems.

[0029] In the open state, the rotating connector not only allows the lamp cover to rotate relative to the base and open, but also causes the lamp cover to move upwards a certain distance during the rotation process. This ingenious design greatly increases the opening space between the lamp cover and the base, providing a more spacious and convenient operating environment for personnel to install and maintain the internal components of the lamp. Installation and maintenance personnel no longer need to operate with difficulty in a confined space, enabling them to install, disassemble, adjust, and replace components more easily and efficiently, significantly shortening installation and maintenance time, improving work efficiency, and reducing operational difficulty and the probability of errors.

[0030] 2. This utility model provides a first limiting member and a second limiting member on both sides of the rotating connector on the base and lamp cover, respectively. The first limiting member limits the rotating connector after the lamp cover is rotated open, effectively restricting its further rotation in the opening direction. The second limiting member, in the same state, limits the lamp cover, preventing it from rotating further in the opening direction. Through the coordinated operation of these two limiting members, the rotation of the connecting member due to excessive rotation, causing the lamp cover to rotate, can be precisely prevented when the lamp cover is open, thus effectively eliminating the possibility of interference or collision between the lamp cover and the base or other components. This design greatly improves the safety of the lamp during use, avoids component damage and structural deformation caused by collisions, ensures the stable operation of the lamp, and reduces safety hazards and maintenance costs caused by accidental collisions.

[0044] Example 1

[0045] See Figures 1 to 8 The core of this utility model is to provide a rotating sealing structure for lamp cover 1 and base 2 for rotating connection and sealing of electrical cavity on base 2, including rotating connector 3, fixing component and elastic compression sealing component.

[0046] The two ends of the rotating connector 3 are rotatably connected to the lamp cover 1 and the base 2, respectively. The lamp cover 1 can rotate relative to the base 2 and rotate and translate relative to the base 2 through the rotating connector 3, so that the lamp cover 1 can be parallel to the base 2 and cover it. Specifically, the rotating connector 3 is provided at one end of the base 2 and / or the lamp cover 1. In this embodiment, the length of the lamp cover 1 is greater than that of the base 2. The rotating connector 3 is provided at one end of the base 2, and in this embodiment, there are two rotating connectors 3, respectively provided on both sides of the base 2.

[0047] An elastic compression sealing assembly is disposed between the lamp cover 1 and the base 2 and surrounds the electrical cavity. The elastic compression sealing assembly includes an elastic seal. The elastic compression sealing assembly is configured to seal the electrical cavity by compressing the elastic seal when the lamp cover 1 is closed on the base 2. A fixing assembly is used to fix the lamp cover 1 and the base 2 together when the lamp cover 1 is closed on the base 2. The elastic compression sealing assembly compresses the elastic seal through the fixing force of the fixing assembly. In this embodiment, the elastic seal is a sealing ring 6.

[0048] Specifically, the elastic compression sealing assembly includes an annular protrusion 4 and an annular sealing groove 5. One of the annular protrusion 4 and the annular sealing groove 5 is located on the lamp cover 1, and the other is located on the base 2. The sealing ring 6 is located inside the annular sealing groove 5. The annular protrusion 4 and the annular sealing groove 5 are arranged opposite to each other. When the lamp cover 1 is closed on the base 2, the annular protrusion 4 extends into the annular sealing groove 5 to compress the sealing ring 6. The sealing ring 6 elastically deforms and cooperates with the groove wall of the annular sealing groove 5 to achieve a seal.

[0049] Furthermore, the end of the sealing ring 6 facing the annular protrusion 4 is provided with a slot 7. When the annular protrusion 4 extends into the annular sealing groove 5, it is inserted into the slot 7 to compress the sealing ring 6.

[0050] In this invention, the rotating connector 3 is rotatably connected at both ends to the lamp cover 1 and the base 2, respectively. This unique structural design allows the lamp cover 1 to rotate and open relative to the base 2 via the rotating connector 3, enabling the base 2 to flexibly switch between open and closed states. Crucially, the rotatable connection between the lamp cover 1 and the head end of the rotating connector 3, and between the base 2 and the tail end of the rotating connector 3, ensures that when the lamp cover 1 rotates towards the base 2 to close, it can close parallel to the base 2 and the sealing ring 6 downwards. This action characteristic allows the lamp cover 1 to simultaneously and evenly contact and compress all parts of the sealing ring 6, ensuring balanced force on the sealing ring 6. This effectively prevents displacement due to uneven force, thus eliminating localized sealing failures, significantly improving overall sealing performance, providing reliable protection for the internal components of the lamp, extending the lamp's lifespan, and reducing component damage and repair costs caused by sealing problems.

[0051] In the open state, the rotating connector 3 not only allows the lamp cover 1 to rotate and open relative to the base 2, but also causes the lamp cover 1 to move upward a certain distance during the rotation and opening process. This ingenious design greatly increases the opening space between the lamp cover 1 and the base 2, providing a more spacious and convenient operating environment for personnel to install and maintain the internal components of the lamp. Installation and maintenance personnel no longer need to operate with difficulty in a confined space, enabling them to install, disassemble, debug, and replace components more easily and efficiently, significantly shortening installation and maintenance time, improving work efficiency, and reducing operational difficulty and the probability of errors.

[0052] The base 2 and the lamp cover 1 are respectively provided with a first limiting member 8 and a second limiting member 10 on both sides of the rotating connecting member 3;

[0053] The first limiting member 8 is used to limit the rotating connecting member 3 after the lamp cover 1 is rotated open, restricting the rotating connecting member 3 from rotating in the rotation opening direction; the second limiting member 10 is used to limit the lamp cover 1 after the lamp cover 1 is rotated open, restricting the lamp cover 1 from rotating in the rotation opening direction.

[0054] The first limiting member 8 and the second limiting member 10 are located at both ends of the rotating connector 3, respectively; and the first limiting member 8 is located on the side of the rotating connector 3 facing the rotational opening direction, and the second limiting member 10 is located on the side of the rotating connector 3 facing the rotational closing direction.

[0055] Furthermore, the first limiting member 8 is provided with a limiting inclined surface 9, which is inclined in the direction away from the rotating connector 3 and inclined upward; after the lamp cover 1 is rotated open, the rotating connector 3 abuts against the limiting inclined surface 9 by the weight of the lamp cover 1 and the rotating connector 3.

[0056] This invention features a first limiting member 8 and a second limiting member 10 on both sides of the rotating connector 3 on the base 2 and lamp cover 1, respectively. The first limiting member 8 limits the rotating connector 3 after the lamp cover 1 is rotated open, effectively restricting its further rotation in the opening direction. The second limiting member 10, in the same state, limits the lamp cover 1, preventing further rotation in the opening direction. Through the coordinated operation of these two limiting members, the rotating connector 3 can be precisely prevented from excessively rotating and causing the lamp cover 1 to rotate, thus effectively eliminating the possibility of interference or collision between the lamp cover 1 and the base 2 or other components. This design greatly improves the safety of the lamp during use, avoids component damage and structural deformation caused by collisions, ensures stable operation of the lamp, and reduces safety hazards and maintenance costs caused by accidental collisions.

[0057] The lamp cover 1 is provided with a mounting part 11, the rotating connector 3 is rotatably connected to the mounting part 11, and the second limiting part 10 is provided on the mounting part 11.

[0058] The fixing component includes several clips 12, which are disposed on one of the lamp cover 1 and the base 2, and engage with the other of the lamp cover 1 and the base 2 when the lamp cover 1 is closed on the base 2. In this embodiment, the clips 12 are disposed on the base 2.
