Description

Technical Field

[0001] This utility model relates to the field of mounting bracket technology, specifically to an explosion-proof electrical lighting fixture mounting bracket. Background Technology

[0002] As modern society demands higher quality living and working environments, various venues, such as commercial buildings, industrial plants, residences, and public facilities, are increasingly pursuing higher quality, functionality, and aesthetics in lighting. Whether meeting basic daily lighting needs or creating a unique atmosphere for specific environments, suitable lighting fixtures are indispensable. This has spurred the continuous development of the electrical lighting fixture mounting bracket industry to adapt to diverse lighting installation scenarios.

[0003] When using mounting brackets for electrical lighting fixtures, traditional mounting brackets typically place the fixture on top and then extend it upwards for auxiliary installation. However, when the fixture reaches the designated installation position, there is often a certain deviation, making fine adjustments impossible and reducing the efficiency of the equipment. Utility Model Content

[0004] The purpose of this utility model is to provide an explosion-proof electrical lighting fixture mounting bracket to solve the problem mentioned in the background art that traditional mounting brackets generally place the lighting fixture on the top and then extend it upwards for auxiliary installation. However, when the lighting fixture reaches the designated installation position, there is often a certain deviation, which cannot be fine-tuned, thereby reducing the working efficiency of the equipment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an explosion-proof electrical lighting fixture mounting bracket, including an electric telescopic rod, a fixed platform fixedly connected to the top of the electric telescopic rod, a rotating short rod rotatably connected to the top center of the fixed platform, a rotating platform fixedly connected to the top of the rotating short rod, two first fixed short rods relatively fixedly arranged near the bottom edge of the rotating platform, and an adjustment groove longitudinally opened at the top edge of the fixed platform near the front and rear sides.

[0006] In a preferred embodiment, a bidirectional lead screw is rotatably connected between the inner walls of the two adjusting grooves on opposite sides, and adjusting sliders are threadedly connected to the outer surfaces of the bidirectional lead screw near the edges of both ends.

[0007] In a preferred embodiment, a second fixed short rod is fixedly connected to the top of each of the two adjusting sliders, and a transmission arm is rotatably connected to the outer surface of each of the two second fixed short rods, with the other end of the transmission arm rotatably connected to the first fixed short rod.

[0008] In a preferred embodiment, a first annular fixing frame is fixedly sleeved on the outer surface of the electric telescopic rod near the bottom edge, and three limiting frames are equidistantly connected to the outer surface of the first annular fixing frame along the circumferential direction.

[0009] In a preferred embodiment, the outer surface of the electric telescopic rod is slidably connected to a second annular fixing frame, and the outer surface of the second annular fixing frame is rotatably connected to three supporting legs at equal intervals along the circumferential direction, and the supporting legs are rotatably connected to the limiting frame.

[0010] In a preferred embodiment, the outer surface of the electric telescopic rod is provided with a plurality of auxiliary fixing holes at equal intervals along the vertical direction near the bottom edge.

[0011] In a preferred embodiment, the outer surface of the second annular fixing frame is threaded with a threaded fastener, and the threaded fastener corresponds to and fits into the auxiliary fixing hole.

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

[0013] This invention firstly controls the placement angle of the support bracket by sliding the second annular fixing bracket downwards in conjunction with the first annular fixing bracket and the limiting bracket. When the appropriate angle is reached, the second annular fixing bracket is fixed to the outer surface of the electric telescopic rod by twisting the threaded fastener and auxiliary fixing hole. This allows the support bracket to provide stable support for the electric telescopic rod. The lamp to be installed is placed on top of the rotating platform. By controlling the upward extension of the electric telescopic rod, the fixing platform and rotating platform can be raised and lowered synchronously. The raising and lowering of the rotating platform can synchronously move the lamp to be installed. When the lamp to be installed reaches the designated position, there may be a slight deviation. This is addressed by using a bidirectional screw... Rotation can cause the two adjusting sliders and the second fixed short rod to slide inward or outward simultaneously. The first and second fixed short rods are rotatably connected to both ends of the transmission arm. When the adjusting sliders and the second fixed short rod slide inward simultaneously, the transmission arm retracts, causing the rotating table and the lamp to be installed above to rotate in the forward direction. Conversely, rotating the bidirectional screw in the opposite direction causes the adjusting sliders and the second fixed short rod to slide outward simultaneously, causing the transmission arm to extend, thus causing the rotating table to rotate in the reverse direction. The threaded connection has self-locking properties, ensuring stability during adjustment, allowing for fine-tuning, facilitating lamp installation, and improving equipment efficiency.

[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Please see Figures 1-4This utility model provides a technical solution: an explosion-proof electrical lighting fixture mounting bracket, including an electric telescopic rod 1, with a fixed platform 2 fixedly connected to the top of the electric telescopic rod 1. The lifting and lowering of the electric telescopic rod 1 can drive the fixed platform 2 and the rotating platform 4 to lift and lower synchronously. A rotating short rod 3 is rotatably connected to the top center of the fixed platform 2. The rotating short rod 3 is rotatably connected to the fixed platform 2. When the rotating platform 4 is subjected to a rotational force, it can be rotated and adjusted. The top of the rotating short rod 3 is fixedly connected to the rotating platform 4. The rotating platform 4 can be used to place the lighting fixture to be installed, and the lifting and lowering of the rotating platform 4 can synchronously drive the lighting fixture to be installed to move synchronously. Two first fixed short rods 5 are relatively fixedly arranged near the bottom edge of the rotating platform 4. When the first fixed short rods 5 are driven to transmit power, the rotating platform 4 can be rotated. The first fixed short rods 5 can be rotatably connected to one end of the transmission arm 10. Adjustment grooves 6 are longitudinally opened at the top of the fixed platform 2 near the front and rear edges. The adjustment grooves 6 provide space for the adjustment slider 8 to slide inside.

[0022] A bidirectional lead screw 7 is rotatably connected between the inner walls of the two adjusting slides 6 on opposite sides. The rotation of the bidirectional lead screw 7 can drive the two adjusting sliders 8 to slide inward or outward synchronously. The outer surface of the bidirectional lead screw 7 is threaded with adjusting sliders 8 near the edges of both ends. The sliding of the two adjusting sliders 8 can drive the two second fixed short rods 9 to slide synchronously. The top of the two adjusting sliders 8 is fixedly connected with the second fixed short rods 9. The outer surface of the two second fixed short rods 9 is rotatably connected with the transmission arm 10, and the other end of the transmission arm 10 is rotatably connected to the first fixed short rod 5. When the two second fixed short rods 9 slide inward synchronously, one end of the two transmission arms 10 can be driven to retract inward. At the same time, the rotatable connection between the other end of the transmission arm 10 and the first fixed short rod 5 can drive the rotating table 4 to rotate clockwise for adjustment. Conversely, rotating the bidirectional lead screw 7 in the opposite direction controls the adjusting sliders 8 and the second fixed short rods 9 to slide outward synchronously. The extension of the transmission arm 10 can drive the rotating table 4 to rotate in the opposite direction for adjustment.

[0023] A first annular fixing frame 11 is fixedly fitted onto the outer surface of the electric telescopic rod 1 near the bottom edge. Three limiting frames 12 are equidistantly connected to the outer surface of the first annular fixing frame 11 along the circumferential direction. The first annular fixing frame 11 and the limiting frames 12 limit the support angle of the support legs 14. A second annular fixing frame 13 is slidably connected to the outer surface of the electric telescopic rod 1. The support angle of the support legs 14 can be controlled and adjusted by raising and lowering the second annular fixing frame 13, making it easier to retract. The outer surface of the second annular fixing frame 13... Three support legs 14 are rotatably connected at equal intervals, and the support legs 14 are rotatably connected to the limiting frame 12. Multiple auxiliary fixing holes 15 are equidistantly opened in the vertical direction at the edge near the bottom end of the outer surface of the electric telescopic rod 1. The outer surface of the second annular fixing frame 13 is threadedly connected to a threaded fixing member 16, and the threaded fixing member 16 corresponds to and fits with the auxiliary fixing holes 15. By setting the auxiliary fixing holes 15 and the threaded fixing member 16, the second annular fixing frame 13 can be fixed to the outer surface of the electric telescopic rod 1 by twisting the threaded fixing member 16 and the auxiliary fixing hole 15.

[0024] Working principle: When the lamp mounting bracket is in use, the second annular fixing bracket 13 is slid down to engage with the first annular fixing bracket 11 and the limiting bracket 12 to control the mounting angle of the support leg 14. When the appropriate angle is reached, the threaded fastener 16 is twisted to fix it to the auxiliary fixing hole 15, thus fixing the second annular fixing bracket 13 to the outer surface of the electric telescopic rod 1. This allows the support leg 14 to provide stable support for the electric telescopic rod 1. The lamp to be installed is placed on top of the rotating platform 4. By controlling the electric telescopic rod 1 to extend upward, the lifting and lowering of the electric telescopic rod 1 can drive the fixing platform 2 and the rotating platform 4 to lift and lower synchronously. The lifting and lowering of the rotating platform 4 can drive the lamp to be installed to move synchronously. When the lamp to be installed reaches the designated position, there may be a certain deviation. The rotation of the bidirectional lead screw 7 can drive the two adjusting sliders 8 and the second fixed short rod 9 to slide inward or outward simultaneously. The first fixed short rod 5 and the second fixed short rod 9 are rotatably connected to both ends of the transmission arm 10. When the adjusting sliders 8 and the second fixed short rod 9 slide inward simultaneously, the transmission arm 10 can be retracted, thereby driving the rotating table 4 and the lamp to be installed above to rotate in the forward direction for adjustment. Conversely, rotating the bidirectional lead screw 7 in the opposite direction can drive the adjusting sliders 8 and the second fixed short rod 9 to slide outward simultaneously, thereby driving the transmission arm 10 to extend, thereby driving the rotating table 4 to rotate in the reverse direction for adjustment. The threaded connection has self-locking properties, ensuring stability during adjustment, allowing for fine-tuning, facilitating lamp installation, and improving the working efficiency of the equipment.

[0025] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
