Abstract

The utility model relates to a show frame, which comprises a top frame (1), a bottom frame (3), wherein, a winding shaft (6) is arranged in the bottom frame (3) which is provided with an opening on the upper part, and one end of the winding shaft (6) is connected with the bottom frame (3) in a pivotal way. The utility model is characterized in that a core axle (10) of a torsional spring is axially inserted into an inner cavity of the other end of the winding shaft (6), and a torsional spring (9) is sheathed on the upper part of the core axle (10) of a torsional spring. One end of the torsional spring (9) is connected with the core axle (10) of a torsional spring, and the other end of the torsional spring (9) is connected with the winding shaft (6), and furthermore, the end of the core axle (10) of a torsional spring is connected with the bottom frame (3). If the core axle of a torsional spring is rotated, the torsion which exists between the winding shaft and the core axle of a torsional spring is adjustable, particularly the torsion of long display boards or short display boards is adjustable so as to cause the display boards to reach an optimum operating state. The utility model has the advantage of wide applicability.

Description

Showing stand

The utility model relates to a kind of showing stand that advertising is used that is used for.

In the prior art, showing stand comprises upper frame, underframe, be provided with Graphic Panel and be connected support between upper frame and the underframe, be provided with spool in the described underframe, underframe is provided with opening, volume has and shows drawing board and stretch out from described opening that described spool is provided with torsion spring and makes that Graphic Panel can be automatically by spool retraction on the spool.But the torsion of existing spool can not be regulated, and makes Graphic Panel all be released back torsion maximum, and all is retracted back torsion minimum at Graphic Panel, and inconvenient operation is unsuitable for the folding and unfolding of the Graphic Panel of all size.

But the purpose of this utility model is to provide a kind of showing stand of manual adjustment spool torsion.

The technical solution of the utility model is: a kind of showing stand, comprise upper frame, underframe, be provided with spool in the described underframe, underframe is provided with opening, one end and the described underframe of described spool are pivotally connected, axially be inserted with the torsion spring mandrel in the other end inner chamber of described spool, be with torsion spring on the described torsion spring mandrel and between the internal chamber wall of described torsion spring mandrel and spool, one end of described torsion spring is connected with described torsion spring mandrel, the other end of described torsion spring is connected with described spool, one end of described torsion spring mandrel protrudes from the other end of described spool, and described this end of torsion spring mandrel is connected with described underframe.

The utility model compared with prior art has following advantage:

Twisting torsion spring mandrel can be regulated the torsion between spool and the torsion spring mandrel, therefore can operate easily for the user, and the particularly long and short Graphic Panel that differs can be regulated its torsion makes it reach optimum Working, makes applicability of the present utility model wide.

The utility model will be further described below in conjunction with drawings and Examples:

Accompanying drawing 1 is a stereogram of the present utility model;

Accompanying drawing 2 is the cutaway view of underframe part of the present utility model;

Accompanying drawing 3 is the left side enlarged drawing of accompanying drawing 2;
