Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated.
As Fig. 1, Fig. 2, shown in Fig. 3, the utility model provides a kind of spring 6 pitch of the laps structure of post stand, comprise the end socket 3 that rolls left, the pin-and-hole 11 of an end socket 3 top-side that rolls left described in being positioned at, stationary shaft 1, be arranged on the flat spindle nose 2 on stationary shaft 1 top, axostylus axostyle 5, balance plate 10, spring 6, described axostylus axostyle 5 top is fixed on the one end away from described flat spindle nose 2 on stationary shaft 1, roll left described in described stationary shaft 1 is set in an end socket 3, it is characterized in that: described in roll left bottom an end socket 3 and be provided with thread segment, sidewall is provided with strengthens fixed block 4, described spring 6 one end is surrounded on described thread segment, the described spring 6 extended from described thread segment is around being fixed on described reinforcement fixed block 4, be provided with prong 7 bottom screw rod, described spring 6 other end is positioned in described prong 7, and described axostylus axostyle 5 bottom outer wall is along the circumferential direction provided with groove 9, and described balance plate 10 is movably fixed in described groove 9.
Wherein, described flat spindle nose 2 can be used for applying twisting resistance as handle to described spring 6, and flat spindle nose 2 is fixed on end casing through the connecting hole on end casing simultaneously, thus extension spring is fixed on the body of post stand.
Wherein, described pin-and-hole 11 act as fixation, axostylus axostyle 5 is rotated, when spring 6 produces certain torsion, pin is inserted in described pin-and-hole 11 with the elastic force of fixing spring 6.
Further, described reinforcement fixed block 4 comprises cylindrical fixing portion 41 and rondelle stopper section 42.
Further, described stopper section 42 diameter is greater than described fixed part 41, avoids spring 6 to be connected with fixed part 41 through repeatedly resilience and loosens and fixed part 41 of scurrying out.
Further, described prong 7 wall is provided with the breach 8 of linearly type arrangement.Mainly increase the friction force between spring 6 and axostylus axostyle 5, ensure the fastness that spring 6 end is connected with axostylus axostyle 5.
Further, described breach 8 is semicircle or serrate.
Further, the breadth extreme of described breach 8 is greater than the diameter of described pitch of the laps spring 6.Ensure that spring 6 can be positioned in breach 8, when spring 6 is increased by rotation elasticity, the spring 6 be fixed in breach 8 is not easily shifted.
Further, ringwise, the degree of depth of described groove 9 is less than the radius of described axostylus axostyle 5 to described groove 9.
Further, be provided with through hole in the middle of described balance plate 10, described balance plate 10 is set in described groove 9.
Further, the diameter of described through hole is more than or equal to the interior diameter of described groove 9.Ensure that when twisting described flat spindle nose 2, axostylus axostyle 5 can rotate easily in balance plate 10, avoids in use procedure to reverse and is obstructed and again dismantles finishing.
During use, twist flat spindle nose 2, give spring 6 one torsion in advance, the large I of torsion ensures that the number of turns of cylinder is greater than the length of painting canvas, and general painting canvas is involved in base the power needing two kilograms completely, and spring 6 of the present utility model can produce the torsion of eight kilograms; Discharging torsion by spring 6 can retract in cylinder base by painting canvas, stretching painting canvas tightens up spring 6, reaches the object of showing picture.
Above an embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
