Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of lighting, in particular to a floodlight with rapidly adjustable angles. Background Art
[0002] In the field of lighting, floodlights are widely used in many occasions, such as stage performances, architectural lighting, stadium lighting, exhibitions, etc. However, traditional floodlights have many problems in angle adjustment.
[0003] On the one hand, the structural design of many traditional floodlights is not reasonable. Their angle adjustment function often requires complex mechanical structures to achieve, resulting in the entire floodlight being bulky and loose in structure. This not only takes up a large space during installation, bringing difficulties to the installation work, but also easily affects the stability and durability of the equipment due to problems such as loose components during long-term use, increasing maintenance costs and frequency.
[0004] On the other hand, in terms of operation, the angle adjustment of traditional floodlights is cumbersome and complicated. For tilt and steering adjustments, professional tools or the cooperation of multiple people are often required, and the adjustment accuracy is low, making it difficult to quickly and accurately achieve the required lighting angle. In some occasions where frequent adjustment of lighting angles is required, such as real-time adjustment of lighting angles according to the actors' movements and performance content during stage performances, traditional floodlights cannot meet the needs of fast and flexible adjustment, which seriously affects the lighting effect.
[0005] In addition, after adjustment, due to the lack of an effective stabilization mechanism, the floodlight is easily affected by external vibrations or unexpected external forces, resulting in changes in angle. This instability is unacceptable in many scenarios with strict requirements on lighting angles. For example, building facade lighting needs to maintain a fixed angle for a long time to achieve a specific lighting design effect, which traditional floodlights cannot guarantee.
[0006] Therefore, in order to overcome the shortcomings of the above-mentioned traditional floodlights in angle adjustment, improve the flexibility, stability and ease of operation of the floodlights, and meet the fast and accurate lighting needs of different occasions, the utility model designs a floodlight with quickly adjustable angle.

Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.
[0031] Reference Figure 1-5 , a floodlight with quickly adjustable angle, including a lamp body 1, a mounting base 3, a strip plate 2 and a support column 21, the support column 21 is fixedly mounted on the top side of the strip plate 2, the back side of the lamp body 1 is hingedly mounted on the top of the support column 21, a support shaft 31 is rotatably mounted on the mounting base 3, and the top end of the support shaft 31 is fixedly mounted on the bottom side of the strip plate 2, a strip opening is opened on the strip plate 2, a slider 4 is damped and slidably mounted in the strip opening, and support rods 41 are hingedly mounted on the front and rear sides of the slider 4, two hinge blocks 42 are fixedly mounted on the back side of the lamp body 1, and the ends of the two support rods 41 away from the slider 4 are respectively hingedly mounted on the corresponding hinge blocks 42, so that the inclination angle of the lamp body 1 can be adjusted by cooperating with the hinge blocks 42 when the slider 4 slides along the strip opening;
[0032] A support ring 202 is fixedly mounted on the mounting base 3 based on the support shaft 31. A plurality of support wheels 201 are rotatably mounted on the bottom side of the strip plate 2. The plurality of support wheels 201 are rotatably mounted on the top side of the support ring 202, which can ensure that the strip plate 2 rotates stably based on the support shaft 31. A rotating shaft 43 is rotatably mounted on one side of the slider 4. One end of the rotating shaft 43 extends outside the strip opening and is fixedly mounted with a stopper 431, so that the strip plate 2 can drive the lamp body 1 to perform steering adjustment through the stopper 431 and the rotating shaft 43.
[0033] A plurality of limiting grooves are provided on the support ring 202 based on the support shaft 31 as the center. A toothed plate 52 is slidably mounted on the strip plate 2. A sleeve 5 is rotatably mounted on the inner wall of one side of the strip opening. The sleeve 5 is axially slidably connected to the rotating shaft 43. A gear 51 is fixedly sleeved on the sleeve 5. The toothed plate 52 meshes with the gear 51, and the bottom end of the toothed plate 52 extends to the bottom of the strip plate 2 and is inserted into the corresponding limiting groove, which can limit the strip plate 2, thereby preventing the lamp body 1 from automatically rotating after adjustment is completed.
[0034] The top end of the tooth plate 52 extends to above the strip plate 2 and is fixedly installed with an L-shaped block 53. The same spring 54 is fixedly installed on the top side of the L-shaped block 53 and the strip plate 2, which can control the tooth plate 52 to maintain the downward movement when the handle is released. Therefore, there is no need for the operator to specifically reverse the rotation shaft 43 to control the tooth plate 52 to be inserted into the limit groove, and the tooth plate 52 can be automatically stuck in the limit groove.
[0035] In this embodiment, in order to ensure that the slider 4 maintains stable sliding in the strip-shaped opening, multiple guide rods 401 arranged parallel to each other are fixedly installed on the inner walls on both sides of the strip-shaped opening, and the multiple guide rods 401 are all connected to the slider 4 for damping sliding.
[0036] In this embodiment, the handle is fixedly installed on a side of the stopper 431 away from the rotating shaft 43 to facilitate the operation of the operator.
[0037] In this embodiment, in order to ensure that the rotation of the rotating shaft 43 drives the sleeve 5 to rotate without affecting the sliding of the rotating shaft 43 along the axial direction of the sleeve 5, thereby achieving the purpose of facilitating the control of the lifting and lowering of the tooth plate 52, a guide block 501 is fixedly installed on the inner wall of the sleeve 5, and a guide opening 502 is opened on the rotating shaft 43, and the guide block 501 is damped and slidingly installed in the guide opening 502.
[0038] In this embodiment, in order to facilitate installation of the device at a desired location, a plurality of mounting legs with mounting holes are fixedly mounted on a side of the mounting base 3 away from the support shaft 31 .
[0039] Working principle: When in use, first install the device in the desired position through the mounting legs on the mounting base 3, then pull the rotating shaft 43 by the handle to control the slider 4 to slide along the strip-shaped opening and multiple guide rods 401, and with the cooperation of the two support rods 41 and the two hinge blocks 42, the lamp body 1 can be controlled to adjust the inclination angle. At this time, if the lamp body 1 needs to be steered, the stopper 431 is controlled by the handle to drive the rotating shaft 43 to rotate, and with the cooperation of the guide block 501 and the guide opening 502, the sleeve 5 can be controlled to rotate and drive the tooth plate 52 to move upward. The upward movement of the tooth plate 52 will control the L-shaped block 53 to stretch the spring 54, and at the same time the tooth plate The bottom end of 52 is disengaged from the limit groove, and then the strip plate 2 is controlled to rotate to the desired position based on the support shaft 31. After the adjustment is completed, the handle is released. Under the action of the reaction force of the spring 54, the L-shaped block 53 can be controlled to drive the tooth plate 52 to move downward and be inserted into the corresponding limit groove. Since the slider 4 maintains a damped sliding connection with the guide rod 401, and the slider 4 is also installed in the strip mouth with damped sliding, the slider 4 can be stably maintained in the adjusted position when the rotating shaft 43 is not pushed or pulled, thereby avoiding the situation where the lamp body 1 changes in inclination and rotates by itself when no adjustment operation is performed.
