Description

Technical Field

[0001] This utility model relates to the field of lighting technology, specifically to an angle-adjustable floodlight. Background Technology

[0002] Floodlights, as a type of large-area lighting device, are widely used in building exteriors, stadiums, factories, and other scenarios. The adjustability of their illumination angle is one of the core performance characteristics that meets different lighting needs.

[0003] Existing angle-adjustable floodlights typically achieve angle adjustment through the rotation of the bracket and the lamp body, and are usually secured with bolts after adjustment. This structure has significant drawbacks: the bolt tightening operation is cumbersome, requiring repeated tightening with tools to complete the positioning, resulting in low adjustment efficiency; after long-term use, the bolts are prone to rust or stripping, leading to locking failure, causing the lamp body angle to easily shift, and affecting the stability of the lighting.

[0004] To address the aforementioned issues of inconvenient adjustment and unreliable positioning, there is an urgent need for an angle-adjustable floodlight that is simple in structure, easy to adjust, and has a stable positioning, in order to improve operational efficiency and reliability.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0026] This utility model provides an angle-adjustable floodlight.

[0027] In this embodiment, refer to Figure 1-6 The angle-adjustable floodlight includes a housing 1, a bottom cover 2, a junction box housing 3 and a junction box housing cover 5, as well as a connecting plate 6, a locking sleeve 7, a bracket 8, a pin 9 and a return spring 10. The connecting plate is fixedly connected to the outer shell, and the locking sleeve is fixedly connected to the outer shell. The connecting plate and the outer shell are respectively provided with a connecting hole 11 and a shaft hole 12. The bottom of the shaft hole 12 is provided with a pin hole 13. The end of the bracket is provided with a rotating shaft 14, which passes through the connecting hole and extends into the shaft hole to be rotatably connected to the connecting plate and the outer shell. The end face of the rotating shaft is circumferentially distributed with several positioning grooves 15. The pin is telescopically engaged with the pin hole, and the return spring is fitted on the pin to provide elastic force for the pin to slide towards the positioning groove 15. One end of the pin has a positioning protrusion 16 that matches the positioning groove, and the other end extends out of the shaft hole as a handle 17.

[0028] In the above technical solution, the connecting plate is fixed to the outer shell, and the rotating shaft of the bracket passes through the connecting hole of the connecting plate and extends into the shaft hole of the outer shell to realize the rotational connection between the lamp body and the bracket; under the action of the return spring, the positioning protrusion of the pin is adapted to engage with the positioning groove distributed on the circumference of the rotating shaft end face to form angular positioning; pulling the pin handle can release the positioning, and after rotating the lamp body to the target angle, releasing the handle will cause the pin to re-engage under the action of the spring force to complete the positioning.

[0029] This allows for convenient adjustment and stable positioning of the floodlight's illumination angle, which can be operated without tools, improving adjustment efficiency. The reset spring continuously provides elasticity to ensure reliable positioning and prevent angle deviation. Furthermore, the overall structure is simple and facilitates production and assembly.

[0030] Specifically, the outer ring of the end of the lock sleeve is provided with a fixing ring 18, and a plurality of fixing holes 19 are distributed at intervals on the fixing ring.

[0031] In this embodiment, the fixing ring and the spaced fixing holes on the outer ring of the lock sleeve end can be used to fix the lock sleeve to the outer shell using fasteners (such as bolts).

[0032] Specifically, the handle is provided with a handle hole 20.

[0033] In this embodiment, the handle hole allows fingers to be inserted or tools such as hooks to be used to apply force, making it easy to pull the pin.

[0034] Specifically, a first anti-detachment step 21 is provided at the bottom of the shaft hole, and a second anti-detachment step 22 is provided at the top of the pin.

[0035] In this embodiment, the first anti-disengagement step at the bottom of the shaft hole and the second anti-disengagement step at the top of the pin form a limiting fit, restricting the maximum extension and retraction stroke of the pin.

[0036] Specifically, a directional concave surface 23 is provided on one side of the shaft hole, and a directional protrusion 24 adapted to the directional concave surface is provided on the pin.

[0037] In this embodiment, the directional concave surface on one side of the shaft hole slides into the directional protrusion on the pin, restricting the circumferential rotation of the pin.

[0038] Specifically, one end of the return spring abuts against the first anti-disengagement step at the bottom of the shaft hole, and the other end abuts against the second anti-disengagement step of the pin.

[0039] In this embodiment, the two ends of the reset spring abut against the first anti-disengagement step and the second anti-disengagement step respectively, so that the spring is in a pre-compressed state, providing the pin with a continuous and stable elastic force towards the positioning groove side.

[0040] Specifically, the clearance between the rotating shaft and the connecting hole and shaft hole is 0.1-0.3mm, and the mating surfaces are coated with a lubricating oil film.

[0041] In this embodiment, the clearance between the rotating shaft and the connecting hole and shaft hole is controlled at 0.1-0.3mm to reduce loosening of the fit; the mating surfaces are coated with a lubricating oil film to reduce rotational friction resistance.

[0042] Attention all technical personnel: Although this utility model has been described according to the specific embodiments above, the concept of this utility model is not limited to this utility model. Any modification that utilizes the concept of this utility model will be included within the scope of protection of this patent right.
