The invention relates to a supporting device with the adjustable supporting height and a lamp fitting. The supporting device with the adjustable supporting height comprises a supporting rod, a fixed frame and a tension spring, wherein the fixed frame is used for connecting objects, a supporting rod installing plate is arranged on the fixed frame, the support rod can be correspondingly and glidingly penetrated and arranged in the supporting rod installing plate, one end of the tension spring is fixedly connected with the tail end of the supporting rod, the other end of the tension spring is fixedly connected on the fixed frame, a locking device is arranged on the fixed frame, the locking device can tightly lock the fixed frame on the supporting frame after the fixed frame is regulated to apreset supporting height, the supporting rod can slide in the supporting rod installing plate for tensioning the spring, and the regulated supporting height is controlled through controlling the sliding distance of the supporting rod. The supporting device with the adjustable supporting height of the invention has the advantages of simple structure and convenient use, and is particularly applicable to the supporting of railway illumination lamp fittings on rails in the sliding process.
Description
technical field [0001] The invention relates to a support device, in particular to a support device with adjustable support height. The invention also relates to a luminaire with a support device with adjustable support height. Background technique [0002] Lamps used for railway lighting generally need to walk on the rails, and generally use the wheels set on the lamps to roll and walk. When walking, except for the rolling wheels contacting the rails, the rest of the lamps are suspended in the air. When it is necessary to stop the lamps, It is easy to place unstable and pose a safety hazard. Therefore need people to go to hold lamps and lanterns, prevent it from falling to the ground. This not only wastes manpower, but also increases the labor intensity, which brings great trouble to the railway operation. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an easy-to-use support device and a lamp with adjustable...
