Description

The anti-lost pen cap of signature pen

Technical field

The utility model belongs to a kind of lettering pen, is concretely a kind of anti-lost pen cap of signature pen.

Background technology

Present either student or office worker, common pen is essentially all signature pen, in order to protect signature pen tip, Pen cap is provided on penholder, but pen cap does not pay attention to slightly or roll to fall to be easily lost, this just influence signature pen collect or The water of signature pen can be stained with to hand when person writes.Therefore there is Patent No.：201520811381.1 entitled：It is a kind of anti-lost Lid signature pen, it is bigger for penholder modification although the structure can prevent pen cap from losing, therefore also have for the structure The possibility advanced optimized.

Utility model content

In view of the presence of problem above, the utility model provides a kind of anti-lost pen cap of signature pen, have it is simple in structure, can The characteristics of preventing pen cap head from losing.

A kind of anti-lost pen cap of signature pen, including pen cap head and penholder, the pen cap headgear is on penholder, it is characterised in that： It is evenly arranged with four vertical grooves on the penholder periphery wall, is provided on the pen cap head inner wall and fit depressions Sliding block, the sliding block is resiliently arranged on pen cap head inner wall, and the pen cap head is through-hole；It is set on the pen cap head inner wall Be equipped with dove-tail form groove, the sliding block lower end extends to form fin to both sides and coordinates with dovetail groove notched wall, slider bottom with It is connected with spring between dovetail groove bottom wall.

Further：The upper end of slide block portion is curved portion, and the curved portion coordinates with groove.

Further：In pen cap head opening and pen tip is provided with rubber strip, label are provided on the rubber strip Word pen tip protects plug.

Advantageous effect

The utility model has the beneficial effects that：By the improvement to signature pen penholder and pen cap, it can so that pen cap head can To be slided on penholder outer wall, pen cap head is slided to penholder upper end when needing to write, when without writing Pen cap head is slided, simultaneously because sliding block is to be resiliently arranged in groove, can make pen cap head always effectively and penholder Groove coordinates, and will not sliding block be detached with groove；And it can achieve the purpose that positioning；Pen cap head always together with penholder, The problem of pen cap head is lost is avoided, while this is simple in structure, it is easy to make.

Specific implementation mode

As a kind of embodiment of the utility model, as shown in Figure 1, 2, 3, a kind of anti-lost pen cap of signature pen, including pen Cap head 2 and penholder 4, the pen cap headgear is on penholder, it is characterised in that：It is evenly arranged with four on the penholder periphery wall Vertical groove 5 is provided on the pen cap head inner wall and is resiliently arranged at pen with 5 matched sliding block 8 of groove, the sliding block On cap head inner wall, the pen cap head is through-hole.The structure further groove is located on penholder outer wall and not through entire penholder, it is therefore prevented that Pen cap head skids off the possibility of penholder, while sliding block setting effectively supports pen cap head and reach effective in pen cap head inner wall upper and lower side Prevent from sliding out the purpose of groove.Since pen cap head is through-hole structure, pen cap head can be slided on penholder outer wall, needed Pen cap head is slided to penholder upper end when writing, slides pen cap head when without writing, simultaneously because Sliding block is to be resiliently arranged on pen cap head inner wall, and pen cap head can be made effectively to coordinate always with penholder groove, will not to slide Block is detached with groove；And it can achieve the purpose that positioning；Pen cap head together with penholder, avoids asking for pen cap head loss always Topic, while this is simple in structure, it is easy to make.

In the present embodiment：As shown in Figure 2,3, dove-tail form groove 6 is provided on the pen cap head inner wall, under the sliding block It holds to both sides and extends to form fin 7 and the cooperation of dovetail groove notched wall, spring is connected between slider bottom and dovetail groove bottom wall 9.By be arranged dove-tail form groove, and with the fin of sliding block coordinate, can anti-limited slip block fall, due to sliding block use plastics system At, the fin of sliding block can be installed in dovetail groove by the plasticity of plastics, and both ends of the spring is separately fixed at slider bottom With dovetail trench bottom, it is therefore prevented that spring falls off.

In the present embodiment：As shown in figure 3, the upper end of slide block portion is curved portion, the curved portion coordinates with groove.It will slide Curved portion is arranged with groove abutting end in block, reduces the friction between sliding block and groove, is conducive to sliding not clamping stagnation.

In the present embodiment：As shown in Figure 1, rubber strip 11 is provided in pen cap head opening and towards pen tip, described It is provided with signature pen tip 3 on rubber strip and protects plug 1.Rubber strip is set at pen cap first end, and pen tip will be fixed on rubber strip Plug is protected, can not be collided with effective protection pen tip and damage pen tip.Meanwhile pen cap head is being slided to penholder upper end by rubber strip When can not influence the movement of pen cap head by rubber strip is mobile on pen cap head outer wall, and by pen cap head glide to pen tip into Rubber strip is moved to pen cap hole upper end when row protection and pen tip protection plug is made to coordinate with pen tip.Note：In order to by structure in figure It embodies clear, is amplification assumption diagram.
