Description

The free bullet pen of a kind of more piece

[technical field]

The utility model relates to a kind of bullet pen, and the free bullet pen of particularly a kind of more piece belongs to the stationery field.

[background technology]

Occur the free bullet pen of a kind of more piece at present on the market, it is equipped with in the bullet of rubber, wax crayon or seal the socket of joint head and the tail is made up of more piece, and the outside adds a sleeve of being with the cap for brush.The tubular that two ends communicated about described sleeve was arranged to makes the bullet joint that wherein is arranged in bottom go up rubber, wax crayon or the seal etc. installed and exposes sleeve, so that use.During use, open the cap for brush, and joint is positioned at getting final product bottom of sleeve in that knot bullet that will use; When changing the position of saving in the bullet, joint in the bullet bottom extracted out from the top of sleeve again be pressed into, make the bullet joint that is arranged in time lower end to moving down into bottom, so circulation is till joint moves on to bottom in that knot bullet that will use.There is following shortcoming in the free bullet pen of this more piece: 1, the length of sleeve be fix, therefore limited the number that saves in the bullet of placing in the sleeve, can not be many, can not lack, many wastes have been lacked then and can not have been used; When 2, changing the position of saving in the bullet, joint extraction in the bullet bottom can only be pressed into from the top of sleeve more at every turn, when joint in the bullet that will use is positioned at the position of comparison upper end, expend the very big time could allow it move down into bottom very inconvenience; 3, do not set up the device that carries stamp-pad ink on the free bullet pen of this more piece, when using seal, very inconvenient.

[summary of the invention]

The purpose of this utility model is to provide a kind of more piece free bullet pen, not only is connected firm and uses convenient.

The utility model is achieved in that the free bullet pen of a kind of more piece, comprise in the cap for brush and the more than one bullet and saving, it is characterized in that: in described each bullet joint be provided with one have externally threaded in convergence part and an outer convergence part that has internal thread, in the described bullet joint by interior convergence part external screw thread and another bullet in the screw-internal thread fit of the outer convergence part of joint dock and fix.

The interior convergence part of saving in the described bullet is provided with a storage tank, places rubber or wax crayon or seal in the described storage tank.

The described cap for brush is provided with an outer convergence part that has internal thread, cooperates to be connected with the external screw thread on the convergence part in the joint in the bullet and fixes.

The cap that described cap for brush top is provided with an inner chamber and cooperates with inner chamber is placed an oil storage pad in the described inner chamber.

The utility model has been compared following advantage after adopting said structure with prior art:

1, since in every knot bullet joint be equipped with internal and external screw thread, can be free and dock securely in any another one bullet and save by these screw threads, and do not have the restriction of joint number, can dock long or short length;

When 2, using, save in that knot bullet that only needs to use and screw off, the position that is interfaced directly to bottom gets final product;

3, when the number that saves in the bullet is enough, it can also be made up arbitrarily and be socketed into joint group in several bullets, be equivalent to the free bullet pen of some Zhi Duojie and use simultaneously;

4, also being provided with internal thread on the cap for brush can be connected fixing with the external screw thread cooperation on the joint in arbitrary knot bullet, thereby has increased the free degree that the cap for brush is connected;

5, cap for brush top is provided with an inner chamber in order to place an oil storage pad, uses for seal, and is very convenient.

[specific embodiment]

With reference to shown in Figure 1, be the overall appearance structural representation of the free bullet pen of the utility model, the free bullet pen of a kind of more piece comprises in the cap for brush 1 and several bullets and saves 2, they dock successively from beginning to end by the cooperation of screw thread and form.

Again as shown in Figure 2, be the STRUCTURE DECOMPOSITION figure of the utility model cap for brush, the cap for brush 1 comprises a cap body 11 and a cap 12, the top of described cap body 11 is provided with an inner chamber 112 in order to place an oil storage pad 114, described oil storage pad 114 stores the stamp-pad ink that uses for seal, cap 12 can be enclosed in 112 li of inner chambers with described oil storage pad 114, prevents the stamp-pad ink evaporation.Described cap body 11 belows are provided with an outer convergence part 15 that has internal thread, can with bullet in save and dock; The outer rim of described cap body 11 also is provided with a pen clip 16, so that carry.

As shown in Figure 3, be joint STRUCTURE DECOMPOSITION figure in the bullet of the utility model dress wax crayon, in the described bullet joint 2 be provided with one have externally threaded in convergence part 21 and an outer convergence part 22 that has internal thread, joint 2 can be fixing with the screw-internal thread fit butt joint of joint 2 outer convergence parts 22 in other any one bullet by the external screw thread of interior convergence part 21 in the described bullet, also can dock fixing with the outer convergence part 15 that has internal thread of cap body 11 belows; 21 tops, interior convergence part of joint 2 are provided with a storage tank 212 in the described bullet, place a wax crayon 214 in the described storage tank 212.

As shown in Figure 4, be joint STRUCTURE DECOMPOSITION figure in the bullet of the utility model dress rubber, joint 2 structures are identical in the bullet of its structure and above-mentioned dress wax crayon, uniquely different are, what place in the set storage tank 212 in 21 tops, interior convergence part of joint 2 in the bullet is rubber 216.

In like manner, more as shown in Figure 5, be joint STRUCTURE DECOMPOSITION figure in the bullet of the utility model dress seal, at this moment, what place in the set storage tank 212 in 21 tops, interior convergence part of joint 2 in the bullet is seal 218.

Rubbers of placing in the joint 2 in above-mentioned three kinds of bullets 216 and seal 218 be because of flexible, can be easy to take out in the storage tank 212 of joint 2 from bullet, displacement, also strengthened interest thereby save use cost.

Before the use, can select the kind and the number of joint 2 in three kinds of bullets arbitrarily, head and the tail butt joint successively, screw, again the cap for brush 1 is spun on that bullet joint 2 that places topmost and get final product, revolve get well after as shown in Figure 1, during use, can save 2 from the bullet of optional position dismantles, ressemble, when using seal 218, can screw off cap 12, stamp stamp-pad ink and get final product, very convenient.
