Description

A kind of novel spring pen

Affiliated technical field:

The utility model relates to a kind of writing pen, especially has the hard-tipped pen of spring function.

Background technology:

Present known elastic hard-tipped pen, (patent No. of seeing Xu's root China utility model is ZL98216642.7 " a kind of elastic hard-tipped pen of fluent writing ") that to be part penholder section made by rubber, wire spring elastomeric material, with elastic hard-tipped pen write more smooth, alleviate advantage such as writer fatigue.But because the particularity of spring, make and be difficult on spring, be provided with screw thread and penholder thread connection, because pen is to use the very high commodity of frequency, penholder and spring can be subjected to the various power such as pressure, torsion, folding power of various aspects in long-term use, spring is being bent always, at this moment, the cementing position of spring and penholder will become flexible and come off.

The utility model content:

The elastic hard-tipped pen that provides a kind of spring to connect with penholder or thread connector effective thread is provided the purpose of this utility model.

The utility model is realized by following technical characterictic:

Described penholder inside is provided with the rubber-like pen core, described penholder comprises the spring section, described spring section is made of helical metal bar or wire, described spring section both ends or one end connect with the connecting section of threaded connector or penholder, described spring section is provided with the screw thread that self helical metal bar or wire form, simultaneously, the connecting section of threaded connector or penholder is provided with the screw thread of the corresponding coupling of screw thread that forms with spring section self helical metal bar or wire at the conjunction plane with the spring section.The collar extension of the connecting section of described threaded connector or penholder has the lead angle of being convenient to connect.

The screw thread that described spring section self helical metal bar or wire form, have only in one case and can not form internal and external threads, that helical metal bar or cross section wiry that is exactly formation spring section is square, and be close around, simultaneously close do not have the space between each the helical ring bar that makes spring, promptly the outside is level and smooth as pipe in the spring of Xing Chenging.

The utility model has the advantages that: adopted above scheme, made spring connect with the thread connector effective thread, and simple in structure.

The specific embodiment

Embodiment one, with reference to shown in Figure 1, coil component spring section 3 two ends are inboard to be connected with the connecting section outside screw of threaded

connector

2 and 4,2 and 4 other ends respectively with pen point casing 1 and penholder 5 thread connection, the cross section that constitutes the helical metal bar of spring section 3 is a pentagon, and be close around, spring section 3 self helical metal bar forms internal thread, there is not external screw thread, threaded connector 2 and 4 connecting section lateral surface are provided with the screw thread of the corresponding coupling of internal thread that forms with spring section 3 self helical metal bar, with reference to shown in Figure 2, like this, coil component spring section 3 just can connect by effective thread with 4 with thread connector 2.

Embodiment two, with reference to shown in Figure 3, coil component spring section 31 two ends are inboard to be connected with the connecting section outside screw of threaded

connector

21 and 41, the cross section that constitutes the helical metal wire of spring section 31 is circular, and be close around, spring section 31 self helical metal wire forms internal and external threads, and threaded

connector

21 and 41 connecting section lateral surface are provided with the screw thread that is complementary, with reference to shown in Figure 4.Like this, coil component spring section 31 just can connect by effective thread with 41 with thread connector 21.

In the present embodiment,, like this, also can connect with the connecting section inside thread of threaded connector in the outside, spring section two ends, scheme summary because spring section 31 self helical metal wire forms internal and external threads simultaneously.

Embodiment three, and with reference to shown in Figure 5, the cross section that constitutes the helical metal bar of spring section 32 is a rectangle, spring not close around, spring section 32 self helical metal bar forms internal and external threads, and threaded connector 22 and 42 connecting section lateral surfaces are provided with the screw thread that is complementary with it, with reference to shown in Figure 6.Like this, coil component spring section 32 just can connect by effective thread with 42 with thread connector 22.

In the present embodiment,, like this, also can connect with the connecting section inside thread of threaded connector in the outside, spring section two ends, scheme summary because spring section 32 self helical metal bar forms internal and external threads simultaneously.Simultaneously, because the 32 periphery out-of-flatnesses of spring section, so be provided with the inboard spiral helicine rubber sheath 6 that is.

Embodiment four, with reference to shown in Figure 7, the cross section that constitutes the helical metal bar of spring section 33 is a triangle, spring close around, spring section 33 self helical metal bar forms external screw thread, do not have internal thread, the connecting section medial surface of threaded connector 23 and penholder 51 is provided with the internal thread that is complementary with it, with reference to shown in Figure 8.Like this, coil component spring section 33 just can connect by effective thread with thread connector 23 and penholder 51.Simultaneously, spring section 33 peripheries are provided with the rubber sheath 61 that external screw thread inboard and spring matches.

Above embodiment is only for the usefulness that the utility model is described, but not to the restriction of utility model, person skilled in the relevant technique, under the situation that does not break away from the utility model spirit and scope, can also make various conversion, change all technical schemes that are equal to and also should belong to category of the present utility model, should limit by each claim.
