Abstract

The invention discloses a showing stand roller which comprises a barrel cap, a ratchet wheel, a pawl and a sliding wedge block, wherein the barrel cap is composed of a bottom plate and a side wall vertical to the bottom plate; the ratchet wheel and the barrel cap are concentrically arranged; the pawl and the ratchet wheel are mutually cooperated; and the sliding wedge block drives the pawl to rotate. The showing stand roller also comprises a first spring and a second spring. The bottom plate is provided with a first stop column for fixing one end of the first spring; the sliding wedge block is provided with a first fixed holding column for fixing the other end of the first spring; the bottom plate is provided with a second stop column for fixing one end of the second spring; and the pawl is provided with a second fixed holding column for fixing the other end of the second spring. When the showing stand roller works, elastic force between the two springs is transferred, the phenomenon that the pawl is damaged because of overlarge elastic force is avoided, and the service life of the showing stand roller is effectively prolonged.

Description

technical field [0001] The invention relates to a display stand, in particular to a display stand roller structure. Background technique [0002] The display stand can be used to display print advertisements and pictures, and is suitable for document centers, libraries, and archives to display catalogs, documents, calligraphy, paintings, and graphics. It can also be used as a screen in mobile film projections and projection TV operations , it is widely used in all walks of life because of its advantages of light and portable, convenient storage and transportation, simple installation and convenient operation. [0003] Existing display racks, such as Chinese Utility Model Patent No. CN200920038423.7 disclose a roll-up display rack, including storage bins, support rods, hanging bars, exhibit rolls and sleeves, the sleeves are rotatably connected to the In the storage bin, the spring rod in the sleeve protrudes out of the storage bin through the connecting piece; the lower end...
