Abstract

The invention discloses a height-adjustable lamp holder and a test lamp. The height-adjustable lamp holder comprises a supporting frame, a constant-force hinge, a lamp body support, a driving assemblyand a plurality of connecting pieces; the constant-force hinge is connected with the supporting frame, the constant-force hinge comprises a plurality of hinge connecting pieces and a plurality of hinge connecting shafts, and the uppermost hinge connecting piece is connected with the supporting frame; all the connecting pieces and all the hinge connecting shafts are connected in a one-to-one correspondence mode, and penetrating holes are formed in the connecting pieces; the lamp body support is connected with the bottommost hinge connecting piece; and the driving assembly comprises a motor, awinding cylinder and a traction line, one end of the traction line is wound around the winding cylinder, the other end of the traction line penetrates through and are wound around the through holes ofthe connecting pieces, and the traction line is used for driving the constant-force hinge to open or contract under the rotation of the winding cylinder to adjust the height of the lamp body support.According to the height-adjustable lamp holder, the traction line is used for driving the constant-force hinge to open or contract under the rotation of the winding cylinder to adjust the height of the lamp body support.

Description

technical field [0001] The invention relates to the technical field of lamp stands, in particular to a height-adjustable lamp stand and a test lamp. Background technique [0002] In the prior art, when performing a rail train collision test, it is necessary to illuminate the train in the track. Wherein the lighting lamp is generally fixed by a lamp holder, and the illumination direction of the lighting lamp is irradiated toward the train during installation. [0003] However, the position of the existing light stand is relatively fixed, and the lighting height cannot be adjusted, which cannot meet the test requirements of trains of different heights. Contents of the invention [0004] Based on this, it is necessary to provide a height-adjustable lamp stand and a test lamp that can adjust the lighting height and meet the test requirements of trains of different heights. [0005] A height-adjustable lamp stand, including: a support frame, a constant force hinge, a lamp bod...
