Description

Technical Field

[0001] This utility model relates to the field of road lighting technology, specifically to a road lighting fixture with a replaceable lens assembly. Background Technology

[0002] Most mainstream LED road lighting fixtures use a tightly fixed structure to install secondary optical lenses. During the use of the fixtures after they leave the factory, on the one hand, their light distribution scheme is fixed and cannot be flexibly adjusted according to the actual lighting needs of the road. On the other hand, when the lenses are damaged due to aging or scratches during subsequent use, they cannot be replaced. Therefore, a road lighting fixture with replaceable lens components is proposed to address the above problems. Utility Model Content

[0003] The purpose of this invention is to provide a road lighting fixture with replaceable lens assembly to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A road lighting fixture with a replaceable lens assembly includes a housing and a lens assembly. The housing has a lens mounting bracket on its inner side. The lens assembly is detachably mounted within the lens mounting bracket. A lens locking strip is fixedly connected to the lens assembly. A connecting plate is fixedly connected to the lens mounting bracket at a position corresponding to the lens locking strip. A fastening seat is fixedly connected to the side of the connecting plate facing the lens assembly. The fastening seat has a fastening groove on its inner side for engaging the lens locking strip. A laterally movable locking pin is slidably connected to the inner side of the connecting plate. One section of the locking pin extends through the fastening groove. A control rod is provided on the side of the connecting plate facing away from the lens assembly, and the control rod passes through the locking pin.

[0006] Preferably, the outer casing and the lens mounting bracket are detachably connected by fastening screws, and an optical lens is provided on the inner side of the lens assembly.

[0007] Preferably, both ends of the lens locking strip are provided with triangular protrusions, and the triangular protrusions of the lens locking strip are engaged with the locking pins that extend into the fastening groove.

[0008] Preferably, an anti-deviation plug is fixedly connected to the inner surface of the fastening seat, and a guide groove is provided on the end face of the lens locking strip to engage with the anti-deviation plug.

[0009] Preferably, the control lever is provided with a short slide and a long slide on its outer side, and both the short slide and the long slide are fixedly connected to the surface of the connecting plate.

[0010] Preferably, the portion of the control rod located between the short slide and the long slide has a bent portion, the locking pin is located between the short slide and the long slide, and the control rod is slidably connected to the short slide, the long slide, and the locking pin.

[0011] Preferably, the control rod extends downward and passes through the lens mounting bracket, and the control rod has an operating handle portion on the outside of the lens mounting bracket.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this utility model, the lens mounting bracket and lens assembly work together to replace the optical lens. It can be flexibly adjusted to meet the actual lighting needs of the road. Moreover, when a single lens ages or wears out, maintenance and replacement can be achieved without complicated tools, thereby improving maintenance efficiency and reducing maintenance costs and risks.

[0014] 2. In this utility model, not only can the entire lens be disassembled by disassembling the lens mounting bracket, but the lens assembly can also be removed individually. During the process of removing the lens assembly individually, the locking pin and the lens locking strip mutually abut against each other to achieve mechanical self-locking, ensuring the reliability and stability of the connection.

[0026] Please see Figures 1-8 This utility model provides a technical solution:

[0027] A road lighting fixture with replaceable lens assembly includes a housing 1 and a lens assembly 3. A lens mounting bracket 2 is provided inside the housing 1. The lens assembly 3 is detachably mounted within the lens mounting bracket 2. This split design facilitates matching and replacement of the lens assembly 3 with different light distribution requirements. The housing 1 and the lens mounting bracket 2 are detachably connected by fastening screws. An optical lens 4 is provided inside the lens assembly 3. A lens locking strip 5 is fixedly connected to the lens assembly 3. Both ends of the lens locking strip 5 are triangular protrusions. The triangular protrusions of the lens locking strip 5 engage with locking pins 9 that extend into the locking grooves, achieving mechanical locking. A connecting plate 8 is fixedly connected to the lens mounting bracket 2 at a corresponding position to the lens locking strip 5. A locking seat 6 is fixedly connected to the side of the connecting plate 8 facing the lens assembly 3. The locking seat 6 has a locking groove on its inner side for engaging the lens locking strip 5. An anti-deviation plug 7 is fixedly connected to the inner surface of the locking seat 6. The end face of the lens locking strip 5 has a groove for engaging the anti-deviation plug. The guide grooves of the heads 7 interlock with each other. During installation, the anti-deviation plug 7 is first inserted into the guide groove to achieve pre-positioning and anti-deviation. A locking pin 9 that moves laterally is slidably connected to the inner side of the connecting plate 8. One end of the locking pin 9 extends to the inner side of the fastening groove. A control rod 12 is provided on the side of the connecting plate 8 facing away from the lens assembly 3. A short slide 10 and a long slide 11 are provided on the outer side of the control rod 12. Both the short slide 10 and the long slide 11 are fixedly connected to the surface of the connecting plate 8 to serve as the control rod. The sliding of 12 provides support and guidance. The part of the control rod 12 located between the short slide 10 and the long slide 11 has a bent part. The locking pin 9 is located between the short slide 10 and the long slide 11. The control rod 12 passes through the locking pin 9 and is slidably connected to the short slide 10, the long slide 11 and the locking pin 9. The control rod 12 extends downward and passes through the lens mounting bracket 2. The control rod 12 has an operating handle part on the outside of the lens mounting bracket 2 to facilitate the operator to apply force.

[0028] Workflow: Insert the lens mounting bracket 2 into the housing 1 and align it with the screw holes on the housing 1. Tighten the screws to install the lens mounting bracket 2 inside the housing 1. During the replacement or removal of the lens assembly 3, first operate the control lever 12, pushing it into the lens mounting bracket 2. At this time, the bent part of the control lever 12 will move within the locking pin 9, and through leverage, pull the locking pin 9 out of the locking groove. At this point, the locking pin 9 separates from the lens locking strip 5, releasing the lock. Once the lens assembly 3 is in the correct position, it can be removed from the lens mounting bracket 2. Align the new lens assembly 3 with the mounting position within the lens mounting bracket 2, and move the lens locking strip 5 into the fastening seat 6. Guided by the anti-deviation plug 7, it will be fully inserted. Finally, pull out the control lever 12. The bent part of the control lever 12 will move in the opposite direction to the aforementioned movement, and through leverage, the locking pin 9 will be reinserted into the fastening groove and form a tight engagement with the triangular protrusion at the end of the lens locking strip 5, thus firmly locking the lens assembly 3 onto the lens mounting bracket 2.
