Description

Technical Field

[0001] This utility model relates to the field of stage lighting technology, specifically a portable stage lighting lamp. Background Technology

[0002] Stage lighting is a lighting equipment used in stage performances to illuminate and create visual effects. Through precise control of light intensity, color, distribution, direction, and movement, it shapes stage space, highlights character images, creates specific atmospheres, guides the audience's gaze, and enhances the artistic appeal and expressiveness of the performance.

[0003] Chinese patent CN216480831U discloses an adjustable stage lighting fixture. This lighting fixture, through the setting of a movable frame, a movable frame, and a limiting component, allows the main structure above the lamp holder to be adjusted in height according to usage needs. Through the setting of a telescopic mechanism, the top frame at the fixed block position can be moved from one end, thereby clamping the whiteboard and installing the whiteboard at the position of the lighting component for supplementary lighting at any time. As a result, it not only reduces the burden on the staff, but is also more convenient to use and can be flexibly moved to meet the needs.

[0004] During stage performances, actors often change positions on stage, so the lighting also needs to be adjusted to keep up with the actors. Although the aforementioned patent can use the mobility of the casters to rotate the lamp holder and adjust the horizontal angle of the lighting, it is inconvenient and not flexible enough in actual operation. In addition, the whiteboard in the aforementioned patent is fixed in position and cannot move with the lighting when the height angle is adjusted, thus reducing the supplementary lighting effect. Utility Model Content

[0005] The purpose of this invention is to provide a portable stage lighting fixture that effectively solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution.

[0007] A portable stage lighting fixture includes a cross-shaped movable base, a whiteboard, and a lamp holder. A support rod is rotatably mounted on the upper surface of the cross-shaped movable base, and a mounting bracket is attached to the end of the support rod. The lamp holder is rotatably mounted between the two side walls of the mounting bracket, and a lighting lamp is mounted on the surface of the lamp holder. Fixing plates are mounted on both the upper and lower sides of the lamp holder. Storage slots are formed at both ends of the fixing plates, and cantilever arms are slidably mounted inside the storage slots. L-shaped connecting rods are rotatably mounted at the ends of the cantilever arms, and clamping mechanisms are provided at the ends of the L-shaped connecting rods to secure the whiteboard. Locking mechanisms are provided on the outer sides of the two upper L-shaped connecting rods to fix their angle.

[0008] Furthermore, the clamping mechanism includes a U-shaped block installed at the end of the L-shaped connecting rod, with a first bolt threaded through and connected to the side wall of the U-shaped block, and a clamping block rotatably installed at the end of the first bolt located inside the U-shaped block.

[0009] Furthermore, the locking mechanism includes a first fixing block installed on the outer surface of the L-shaped connecting rod, a second bolt installed inside the first fixing block, and multiple adjustment holes opened at equal angles around the L-shaped connecting rod on the outer surface of the cantilever, with the second bolt matching the adjustment holes.

[0010] Furthermore, each of the four corners of the cross-shaped movable seat is vertically threaded with a screw rod, a support block is installed at the bottom of the screw rod, and a torsion bar is provided at the bottom of the screw rod.

[0011] Furthermore, the mounting bracket has third bolts for fixing the lamp holder on both sides, a second fixing block is installed on the outer surface of the support rod, a fourth bolt is installed inside the second fixing block, and a fifth bolt for fixing the cantilever is installed on both sides of the outer surface of the fixing plate.

[0012] Furthermore, rubber pads are provided on the inner walls of both the clamping block and the U-shaped block, and anti-slip textures are provided on the outer surface of the rubber pads.

[0013] Furthermore, a through hole is horizontally opened near the top of the screw, and a torsion bar is inserted into the through hole. Both ends of the torsion bar are provided with limit balls.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0015] 1. This utility model uses a rotating screw to drive the support block to support the ground, thereby enabling the entire lamp holder to achieve good stability. Since both the support rod and the lamp holder are installed with damping rotation, the angle of the light can be adjusted by directly rotating the support rod and the lamp holder. The operation is simple and easy to adjust. Furthermore, due to the damping property, the angle of the light can remain fixed when the support rod and the lamp holder are released.

[0016] 2. This utility model uses a fixed plate and cantilever structure to clamp and fix the whiteboard to the outside of the lamp holder, so that the whiteboard can change with the change of light angle and always maintain the supplementary lighting effect. When not in use, the cantilever can also be retracted into the fixed plate, thereby reducing the space occupied, reducing the possibility of scratches, and ensuring good safety.

[0017] 3. By setting up a locking mechanism, this utility model can flexibly adjust the angle of the whiteboard according to different performance needs and scene changes, thereby changing the lighting effect and enhancing the actor's expressiveness. Attached Figure Description

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.

[0024] In the description of the embodiments of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connection" and "installation" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Furthermore, "connection" can be a direct connection or an indirect connection through an intermediate medium. "Fixed" means that the relative positional relationship remains unchanged after the connection. The directional terms mentioned in the embodiments of this utility model, such as "inner," "outer," "top," and "bottom," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this utility model, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this utility model.

[0025] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0026] Please see Figures 1-4 This utility model provides a movable stage lighting fixture, including a cross-shaped movable base 100, a whiteboard 102, and a lamp holder 104. A support rod 101 is rotatably mounted on the upper surface of the cross-shaped movable base 100, and a mounting bracket 103 is mounted at the end of the support rod 101. The lamp holder 104 is rotatably mounted between the two side walls of the mounting bracket 103, and a lighting lamp is mounted on the surface of the lamp holder 104. Fixing plates 105 are mounted on both the upper and lower sides of the lamp holder 104. Storage slots 108 are provided at both ends of the fixing plates 105. Cantilever arms 106 are slidably mounted inside the storage slots 108, and L-shaped connecting rods 107 are rotatably mounted at the ends of the cantilever arms 106. Clamping mechanisms 200 for fixing the whiteboard 102 are provided at the ends of the L-shaped connecting rods 107. Locking mechanisms 300 for fixing the angle of the two upper L-shaped connecting rods 107 are provided on their outer sides.

[0027] In use, the cross-shaped movable base 100 is used to move the light stand to the designated position. Then, the cantilever 106 is pulled out from the light base 104, and the whiteboard 102 is fixed to the end of the cantilever 106 by the clamping mechanism 200 to provide supplementary lighting. Then, the lights on the light base 104 are turned on to provide illumination. During stage performances, the operator can directly rotate the support rod 101 and the light base 104 to adjust the angle of the lights, thus ensuring continuous illumination for the actors. Furthermore, the locking mechanism 300 allows for flexible adjustment of the angle of the whiteboard 102 according to different performance needs and scene changes, thereby altering the supplementary lighting effect and enhancing the actors' expressiveness.

[0028] Preferably, the clamping mechanism 200 includes a U-shaped block 201 installed at the end of the L-shaped connecting rod 107. A first bolt 202 is threaded through and connected to the side wall of the U-shaped block 201. A clamping block 203 is rotatably installed at the end of the first bolt 202 located inside the U-shaped block 201.

[0029] When installing the whiteboard 102, insert it into the two U-shaped blocks 201 on the same side, then tighten the first bolt 202. Under the action of the threaded connection, the clamping block 203 is driven to clamp the outer surface of the whiteboard 102, thereby achieving the function of fixing. Since the clamping block 203 and the first bolt 202 are rotatably connected, when the clamping block 203 contacts the whiteboard 102, the friction force can keep the angle of the clamping block 203 fixed, so that the clamping block 203 is pressed vertically on the whiteboard 102, preventing the whiteboard 102 from rotating with the first bolt 202 and causing the whiteboard 102 to be worn.

[0030] Preferably, the locking mechanism 300 includes a first fixing block 302 installed on the outer surface of the L-shaped connecting rod 107, a second bolt 303 installed inside the first fixing block 302, and a plurality of adjustment holes 301 are opened at equal angles around the L-shaped connecting rod 107 on the outer surface of the cantilever 106, and the second bolt 303 matches the adjustment holes 301.

[0031] When it is necessary to adjust the angle of the whiteboard 102, the second bolt 303 can be unscrewed from the adjustment hole 301 to release the angle fixation of the L-shaped connecting rod 107. Then, the whiteboard 102 can be rotated to adjust the angle. After the angle is adjusted, the second bolt 303 can be screwed into the adjustment hole 301 at the corresponding angle.

[0032] Preferably, each of the four corners of the cross-shaped movable seat 100 is vertically penetrated and threaded with a screw 400, a support block 401 is installed at the bottom of the screw 400, and a torsion bar 402 is provided at the bottom of the screw 400.

[0033] When the screw 400 is rotated, the threaded connection causes the support block 401 to descend and support the ground, and the universal wheels at the bottom of the cross-shaped moving seat 100 to separate from the ground. This allows the entire lamp holder to achieve good stability and prevents the lamp holder from shaking when adjusting the angle of the lighting lamp, which would otherwise lead to unstable lighting effects.

[0034] Preferably, the mounting bracket 103 has a third bolt 500 for fixing the lamp holder 104 on both sides, the support rod 101 has a second fixing block 501 on its outer surface, the second fixing block 501 has a fourth bolt 502 inside its interior, and the fixing plate 105 has a fifth bolt 503 for fixing the cantilever 106 on both sides of its outer surface.

[0035] When the lighting fixture is not in use, the third bolt 500 can be tightened to fix the lamp holder 104, the fourth bolt 502 can be tightened so that its end abuts against the cross-shaped movable seat 100 to fix the support rod 101, the cantilever 106 can be retracted into the fixing plate 105 and the fifth bolt 503 can be tightened to fix it, so that the entire lamp holder can have good stability during movement or transportation.

[0036] Preferably, the inner walls of both the clamping block 203 and the U-shaped block 201 are provided with rubber pads, and the outer surface of the rubber pads is provided with anti-slip texture.

[0037] The rubber pads and anti-slip textures increase the friction with the whiteboard 102, improving the clamping effect. The rubber pads also have deformation capabilities, which can protect the whiteboard 102 during clamping and reduce the possibility of damage or deformation.

[0038] Preferably, the screw 400 has a horizontal through hole near its top position, the torsion bar 402 is inserted into the through hole, and both ends of the torsion bar 402 are provided with limit balls.

[0039] When rotating the screw 400, the torsion bar 402 can slide in the through hole, so that the limiting ball on one end of the torsion bar 400 abuts against the outer surface of the screw 400. At this time, rotating the torsion bar 402 will drive the screw 400 to rotate, which can save effort.

[0040] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
