Description

Technical Field

[0001] This utility model relates to the field of lamp holder technology, specifically a lightweight, reverse-folding lamp holder. Background Technology

[0002] As is well known, current mainstream lighting stands such as aluminum alloy tripods and steel tube supports generally suffer from the following problems: traditional lighting stands are generally bulky and complex in structure, not only heavy but also inconvenient to carry and store. Specifically, to ensure stability, traditional lighting stands use solid metal tubing, such as steel tubing with a diameter ≥40mm, resulting in a single piece often weighing over 3kg. This takes up a lot of space when carried outdoors, leading to high transportation costs. When the unfolded height of lighting stands commonly used in film and television shooting reaches 2.5m, the folded length still exceeds 1.2m, making them unsuitable for small storage spaces in vehicles. Most folding structures rely on multi-level locking bolts. For example, wing nuts require tightening step by step during operation, and unfolding takes more than 3 minutes. In emergency scenarios such as lighting at a news scene, it is difficult to respond quickly. When there are more than 3 folding joints, the structure is prone to joint loosening, requiring repeated leveling. When telescopic light stands retract rapidly, the tube body hits the base due to gravity acceleration, which can easily cause damage to the light fixtures, especially LED modules. Existing solutions rely solely on rubber pads, and the cushioning effect decreases sharply with aging. In dusty and humid environments, traditional light stand slides are prone to jamming, and the hinges are prone to corrosion. After outdoor use, disassembly and cleaning are required, resulting in high maintenance costs. Therefore, it is necessary to propose a solution to this technical problem. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a lightweight reverse-folding lamp holder.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, this utility model provides the following technical solution: a lightweight reverse-folding lamp holder, comprising a small tube, a middle tube, a bottom tube, an M double-threaded hand-twisting mechanism, a first connector, a second connector, a first bottom tube plug, a second bottom tube plug, a first air cushion, and a second air cushion.

[0007] Furthermore, this utility model is improved in that the top of the small tube is connected to the lamp holder head via an open elastic pin, and the lamp holder head is connected to a 1 / 4 inch screw cap. The first bottom tube plug, the first air cushion, and the gasket are fixedly installed at the bottom of the small tube via cross-shaped semi-circular self-tapping screws. The small tube is slidably installed on the inner wall of the middle tube in a sealed fit and is fixed by the first connector. The M5 double-ended thread can be adjusted by hand-twisting.

[0008] Furthermore, the present invention is improved in that the middle tube, the second bottom tube plug, the second air cushion, and the gasket are fixedly installed at the bottom of the middle tube by cross-shaped semi-circular self-tapping screws, and are slidably installed on the inner wall of the bottom tube in a sealed fit. They are fixed by the second connector and can be adjusted by hand-twisting the M5 double-ended thread.

[0009] Furthermore, the present invention is improved by connecting a sealing gasket at the bottom of the bottom tube and connecting the bottom of the iron foot tube to the foot plug.

[0010] Furthermore, the present invention is improved in that the bottom of the iron foot tube is connected to the foot plug; the three iron foot tubes are respectively fixed to the three corresponding ports of the sliding sleeve by semi-hollow round-head iron rivets; the sliding sleeve is then connected to the bottom tube; and it is fixed by M5 double-threaded hand-tightening and external hexagonal eleven-point bolts and second washers, which can be adjusted.

[0011] Furthermore, the present invention is improved in that the iron support bars are connected to the base by rivets; the base is then fixedly connected to the bottom of the base tube; and the iron support bars at the other end are connected to the three iron foot tubes by first washers and rivets.

[0012] (III) Beneficial Effects

[0013] Compared with the prior art, this utility model provides a lightweight, inverted lamp holder, which has the following advantages:

[0014] This lightweight, inverted folding lamp stand features a nested design of small, medium, and bottom tubes and an adjustable sliding sleeve, which allows the lamp stand to maintain structural stability while achieving a lightweight and portable design.

[0015] The lamp holder can be easily folded and unfolded by adjusting the sliding sleeve, connector, and M5 double-threaded hand-twist mechanism, making it easy to carry and store.

[0016] The M5 double-threaded hand-tight design allows for flexible adjustment of the lamp holder's height and angle to meet lighting needs in different scenarios.

[0017] The connection of the iron legs, base, and iron support bars forms a stable triangular support structure, which increases the overall stability of the lamp holder and ensures safety during use.

[0018] The design of the base tube and related components incorporates an air cushion mechanism. This mechanism achieves a slow and smooth descent through changes in air pressure when the light fixture is retracted or its height adjusted, effectively preventing damage to the light fixture due to sudden contraction or impact. Simultaneously, this air cushion design indirectly enhances the light fixture's airtightness, helping to prevent the intrusion of external impurities such as dust and moisture, further protecting the integrity of the internal structure and ensuring normal operation.
