Utility model content
For solving the problems of the technologies described above, the technical scheme that the utility model proposes is: a kind of post stand spring device, comprise roll left an end socket, stationary shaft, axostylus axostyle, balance element, spring, affixed bottom described axostylus axostyle top and stationary shaft, described stationary shaft is provided with a described end socket that rolls left the pin-and-hole matched, roll left described in described fixed hub is located in an end socket, it is characterized in that: bottom described stationary shaft, be provided with thread segment, described axostylus axostyle lower end is fixed on balance element, described spring one end is fixed on described thread segment, and the other end is fixed on described balance element.
Further, described balance element comprises balance plate and fixed part, and described fixed part is for being provided with externally threaded tubular structure, and one end of described spring is fixed on described fixed part.
Further, described fixed part and the integral shaping setting of described balance plate.
Further, fixed orifice is provided with along axis direction in the middle of described balance element.
Further, the diameter of fixed orifice equals the diameter of described axostylus axostyle, and described axostylus axostyle is firmly connected with described balance element through described fixed orifice.
Further, described stationary shaft top is provided with flat spindle nose, and described flat spindle nose and described stationary shaft are one-body molded setting.
Further, described stationary shaft, described flat spindle nose, described in a roll left end socket, described balance element be plastic material.
Further, the number of turns of described spring is 200-215.
The advantage that the utility model has and good effect are:
1, the utility model structural stability is good, balance plate and the fixed part of balance element are one-body molded, to support degree and the raising of balance dynamics of whole spring device, avoid balance plate in prior art to be connected to rotationally on axostylus axostyle, easily driven by axostylus axostyle and rotate thus the shortcoming of good equilibrium activity can not be played;
2, described stationary shaft, described flat spindle nose, described in a roll left end socket, described balance element be plastic material, greatly save cost, and described flat spindle nose and described stationary shaft are one-body molded setting, the balance plate of balance element and the one-body molded setting of fixed part, add the tightness of structure, ensure that the serviceable life of product;
3, the number of coils is arranged on 200-215 circle, ensure that the torsion strength be involved in completely by painting canvas in base, and more soft, more laborsaving at the prerequisite lower pulling force that cost compare is low.
Accompanying drawing explanation
Fig. 1 is decomposition texture schematic diagram of the present utility model;
Fig. 2 is one-piece construction schematic diagram of the present utility model;
Fig. 3 is the structural representation of balance element of the present utility model.
In figure: 1. stationary shaft, 2. flat spindle nose, 3. thread segment, 4. to roll left an end socket, 5. pin-and-hole, 6. axostylus axostyle, 7. spring 8. balance element, 9. balance plate, 10. fixed part, 11. fixed orifices.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated.
As shown in Figure 1, a kind of post stand spring 7 mechanism, comprise the end socket 4 that rolls left, stationary shaft 1, axostylus axostyle 6, balance element 8, spring 7, affixed bottom described axostylus axostyle 6 top and stationary shaft 1, described stationary shaft 1 is provided with the described end socket 4 that rolls left the pin-and-hole 5 matched, axostylus axostyle 6 is rotated, when spring 7 produces certain torsion, pin is inserted in described pin-and-hole 5 with the elastic force of fixing spring 7; Roll left described in described stationary shaft 1 is set in an end socket 4, be provided with thread segment 3 bottom described stationary shaft 1, described axostylus axostyle 6 lower end is fixed on balance element 8, and described spring 7 one end is fixed on described thread segment 3, and the other end is fixed on described balance element 8.
Further, described balance element 8 comprises balance plate 9 and fixed part 10, and described fixed part 10 is for being provided with externally threaded tubular structure, and one end of described spring 7 is fixed on described fixed part 10.
Further, described fixed part 10 and described balance plate 9, in one-body molded setting, increase the steadiness of structure, secure the stressed of spring 7 better simultaneously.
