These caps for brush, due to itself structure, in use, are to be all placed on outside pen hair along pen hair to penholder direction, thereby damage pen hair.

Utility model content

The purpose of this utility model is to provide a kind of writing brush structure with the cap for brush, can be conducive to protect well pen hair.

Above-mentioned technical purpose of the present utility model is achieved by the following technical programs: a kind of writing brush structure with the cap for brush, comprise the cap for brush, penholder and be located at the pen hair of described penholder one end, the described cap for brush comprises at least two pipe boxes, wherein diapire can contact at one end that described penholder is relative with described pen hair in outermost described pipe box, and adjacent described pipe box socket also can axial stretching; Between adjacent two described pipe boxes, be provided with and limit the position limiting structure that this two pipe box causes the relative displacement degree of described cap for brush generation stretching.

The above-mentioned cap for brush in use, from penholder to a cant to stretching, extension, thereby is finally placed on outside pen hair, thereby easy damaged pen hair is not realized the good protection to pen hair; Thereby the cap for brush is formed and is realized flexible form by a plurality of pipe boxes, make the cap for brush when not using, small volume, does not take up space.

As of the present utility model preferred, direction of extension along the described cap for brush is that front end is to rear extreme direction, in adjacent described two pipe boxes, more outer field pipe box rear end is provided with block edge, compared with the sleeve pipe front end of internal layer, be provided with the flange that can conflict with described block edge, described block edge and described flange form described position limiting structure.

As of the present utility model preferably, along the direction of extension of the described cap for brush be front end to rear extreme direction, the diapire of pipe box and be provided with magnetic attracting structure between the front end of pipe box described in all the other described in outermost layer.

Magnetic attracting structure can be two magnetic sheets that magnetic is contrary, also can be comprised of magnetic sheet and sheet metal.

As of the present utility model preferably, the interior diapire of pipe box is fixed on described penholder and described pen mao relative one end described in outermost layer.

In conjunction with above-mentioned magnetic attracting structure, can make the cap for brush under not use state, draw the upper end in penholder in, do not affect on the one hand the normal use of writing brush, make on the other hand the cap for brush be difficult for losing.

As of the present utility model preferably, under described cap for brush rounding state, the rear end of pipe box exceeds the rear end of pipe box described in all the other described in innermost layer.

Be convenient to stretch the cap for brush.

As of the present utility model preferred, under described cap for brush rounding state, except pipe box described in innermost layer, described in all the other, the rear end of pipe box is consistent at the axial location of described penholder.

Be conducive to shorten as far as possible the axial length of the cap for brush under rounding state, be also conducive to improve the aesthetics of the cap for brush simultaneously.

As of the present utility model preferred, between adjacent described two pipe boxes, be provided with and avoid this two pipe box to produce the guide frame of relative radial displacement.

Be conducive to further effectively improve the protection to pen hair.

In sum, the utlity model has following beneficial effect: the utility model is simple in structure, example easy to implement; More can be by the good protection of realizing pen hair.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail.

This specific embodiment is only to explanation of the present utility model; it is not to restriction of the present utility model; those skilled in the art can make to the present embodiment the modification that there is no creative contribution as required after reading this description, but as long as within the scope of claim of the present utility model, are all subject to the protection of Patent Law.

Embodiment 1: as shown in Figure 1-2, a kind of writing brush structure with the cap for brush, comprises the cap for brush 1, penholder 2 and be located at the pen hair 3 of penholder 2 one end.

The cap for brush 1 comprises at least two pipe boxes 11, is shown with three pipe boxes 11 in Fig. 2, can be not only in fact three, can be two or four etc., and shown in Fig. 2, three pipe boxes 11 are only to be convenient to set forth the cap for brush 1 structure.

11 sockets of adjacent pipe box also can axial stretching; Direction of extension along the cap for brush 1 is that front end is to rear extreme direction, in adjacent two pipe boxes 11, more outer field pipe box 11 rear ends are provided with block edge 111, compared with the sleeve pipe of internal layer 11 front ends, be provided with the flange 112 that can conflict with block edge 111, block edge 111 forms position limiting structure with flange 112, for limiting this two pipe box 11, causes the cap for brush 1 to produce the relative displacement degree of stretching; When the cap for brush 1 extends to when ultimate attainment, each position limiting structure is in the inconsistent state of block edge 111 and flange 112, and now, the interior diapire of outermost pipe box 11 contacts at one end that penholder 2 is relative with pen hair 3, and at least the pipe box 11 of innermost layer is just in time placed on outside pen maos 3.

Direction of extension along the cap for brush 1 is extremely rear extreme direction of front end, between the diapire of outermost layer pipe box 11 and the front end of all the other pipe boxes 11, is provided with magnetic attracting structure; Magnetic attracting structure is not shown in the drawings, can be for being located at respectively the diapire of outermost layer pipe box 11 and the magnetic material layer of all the other pipe boxes 11 flanges 112, thereby when the cap for brush 1 draws in, realize the adhesive of the diapire of flange 112 and outermost layer pipe box 11, can certainly magnetic material layer and the structure of the mutual adhesive of metal level, or other can realize the structure of the diapire of outermost layer pipe box 11 and the mutual adhesive of front end of all the other pipe boxes 11.

For avoiding the loss of the cap for brush 1, the interior diapire of outermost layer pipe box 11 also can be fixed on one end that penholder 2 is relative with pen hair 3.

Stretch for convenience the cap for brush 1, be arranged under the cap for brush 1 rounding state, the rear end of innermost layer pipe box 11 should exceed the rear end of all the other pipe boxes 11.

Arrange under the cap for brush 1 rounding state, except innermost layer pipe box 11, the rear end of all the other pipe boxes 11 is consistent at the axial location of penholder 2.

Embodiment 2: as shown in Figure 3-4, be with the difference of embodiment 1, between adjacent two pipe boxes 11, be provided with and avoid this two pipe box 11 to produce the guide frame of relative radial displacement, guide frame can be in adjacent two pipe boxes 11, is located at the axial slide 113 of more outer pipe box 11 inwalls and is arranged at compared with internal layer pipe box 11 inwalls and can slides on the axial raised line 114 of axial slide 113.
