Description

Technical Field

[0001] The utility model relates to the field of storage racks, in particular to a reel torque pre-release telescopic storage rack. Background Art

[0002] There are many kinds of storage racks. General storage racks are rigid structures that cannot or are difficult to store. With the continuous updating and development of products, telescopic storage racks have begun to appear on the market. The principle is to wind a flexible storage sheet on a reel of a wall-mounted base, and set a torsion spring (clockwork spring) at the axis of the reel to provide winding torque for the flexible storage sheet by storing force, and the unfolded end of the flexible storage sheet is fixed on a pull-out plate, and the pull-out plate and the wall-mounted base are hinged by a folding arm, so that the pull-out plate can move horizontally relative to the wall-mounted base and pull out the flexible storage sheet at the same time. Therefore, the current products have already stored force in the torsion spring (clockwork spring) when leaving the factory. Therefore, if they are not used for a long time (such as as inventory), it is easy to cause the stored force of the torsion spring (clockwork spring) to gradually decrease, resulting in its contraction force being less than the preset force when it is used. Utility Model Content

The preset torque is adjusted according to user needs, and then the blocking block is inserted into the blocking groove while the meshing mouth of the blocking block and the meshing portion of the reel are engaged and maintained, thereby achieving the torque setting.

[0006] The utility model is further configured such that the blocking block and the blocking groove are interference fit or snap fit.
