Description

A kind of pen preventing pen core from flowing backwards

Technical field:

The utility model relates to a kind of pen preventing pen core from flowing backwards.

Background technology:

The various gel ink pen of current use and ball pen, mostly comprise the shaft of a writing brush, pen core, the cap for brush and cap, wherein pen core is inserted in the shaft of a writing brush, the cap for brush is plugged on the front end of the shaft of a writing brush, and cap is connected to the rear end of the shaft of a writing brush, and the weak point of this pen core is, people conveniently pick and place pen, often pen is upside down in pen container, the ink in pen core often flows backwards under gravity and makes dirty bottom pen container, cleans pen container bring trouble to people.

Utility model content:

The utility model is in order to make up the deficiencies in the prior art, provide a kind of pen preventing pen core from flowing backwards, structure is simple, reasonable in design, by arranging round rubber block at pen core end, shutoff pen core end, avoiding the ink of pen when being inverted in pen core to flow backwards under gravity and make dirty bottom pen container, cleaning pen container to people and bringing conveniently, solving problems of the prior art.

The utility model for solving the problems of the technologies described above adopted technical scheme is:

A kind of pen preventing pen core from flowing backwards, comprise the shaft of a writing brush, pen core, the cap for brush and cap, wherein pen core is inserted in the shaft of a writing brush, the cap for brush is plugged on the front end of the shaft of a writing brush, cap is connected to the rear end of the shaft of a writing brush, a round rubber block is provided with at cap inner surface, a circular groove matched with pen core end is provided with at round rubber block lower surface, a U-shaped chute arranged in opposite directions is respectively equipped with in the both sides that shaft of a writing brush top is relative, a L shape slide block is respectively equipped with in the side that cap is relative with U-shaped chute, two L shape slide blocks are oppositely arranged, the horizontal segment of two L shape slide blocks respectively active card is connected in two U-shaped chutes.

A seal washer is provided with along the circumferencial direction of circular groove at circular groove inner surface.

The utility model adopts such scheme, structure is simple, reasonable in design, by arranging round rubber block at pen core end, and shutoff pen core end, avoiding the ink of pen when being inverted in pen core to flow backwards under gravity and make dirty bottom pen container, cleaning pen container to people and bringing conveniently.

Accompanying drawing illustrates:

Fig. 1 is sectional structure schematic diagram of the present utility model.

Fig. 2 is the structural representation of U-shaped chute in the utility model.

In figure, 1, the shaft of a writing brush, 2, pen core, 3, the cap for brush, 4, cap, 5, round rubber block, 6, circular groove, 7, U-shaped chute, 8, L shape slide block, 9, seal washer.

Detailed description of the invention:

For clearly demonstrating the technical characterstic of this programme, below by detailed description of the invention, and in conjunction with its accompanying drawing, the utility model is elaborated.

As shown in Figure 1-2, a kind of pen preventing pen core from flowing backwards, comprise the shaft of a writing brush 1, pen core 2, the cap for brush 3 and cap 4, wherein pen core 2 is inserted in the shaft of a writing brush 1, the cap for brush 3 is plugged on the front end of the shaft of a writing brush 1, cap 4 is connected to the rear end of the shaft of a writing brush 1, a round rubber block 5 is provided with at cap 4 inner surface, a circular groove 6 matched with pen core 2 end is provided with at round rubber block 5 lower surface, a U-shaped chute 7 arranged in opposite directions is respectively equipped with in the both sides that the shaft of a writing brush 1 top is relative, a L shape slide block 8 is respectively equipped with in the side that cap 4 is relative with U-shaped chute 7, two L shape slide blocks 8 are oppositely arranged, the horizontal segment of two L shape slide blocks 8 respectively active card is connected in two U-shaped chutes 7.

Be provided with a seal washer 9 at circular groove 6 inner surface along the circumferencial direction of circular groove 6, increase the sealing effectiveness of round rubber block 5 pairs of pen cores 2.

During use, when people need to write, only need hold be arranged on the shaft of a writing brush 1 both sides two L shape slide blocks 8 along U-shaped chute 7 upward sliding, until rotate counterclockwise when sliding into the top of U-shaped chute 7, two L shape slide blocks 8 respectively active card are connected in the upper horizontal segment of two U-shaped chutes 7, cap 4 moves up along the length direction of the shaft of a writing brush 1 under the drive of two L shape slide blocks 8, round rubber block 5 also moves up along the length direction of the shaft of a writing brush 1 under the drive of cap 4, pen core 2 end departs from circular chute 6, and people just can normally use signature pen or ball pen to write, as people, to write work complete, when no longer needing to use signature pen or ball pen, only need hold the two L shape slide blocks 8 being arranged on the shaft of a writing brush 1 both sides first to rotate clockwise along the top of U-shaped chute 7, and then move down along the length direction of U-shaped chute 7, until rotate counterclockwise again when two L shape slide blocks 8 move to the bottom of two U-shaped chutes 7 respectively, two L shape slide blocks 8 respectively active card are connected in the lower horizontal segment of two U-shaped chutes 7, the rotating clockwise of top of cap 4 first along two U-shaped chutes 7 under the drive of two L shape slide blocks 8, and then move down along the length direction that U-shaped chute 7 is suitable, bottom finally along U-shaped chute 7 rotates counterclockwise, until two L shape slide blocks 8 respectively active card be connected in two U-shaped chutes 7, now, pen core 2 end active card is connected in the circular groove 6 of round rubber block 5 lower surface setting, round rubber block 5 shutoff pen core 2 end that pen core 2 end is arranged, avoid the ink of pen when being inverted in pen core 2 to flow backwards under gravity and make dirty bottom pen container, clean pen container to people to bring conveniently.

Above-mentioned detailed description of the invention can not as the restriction to the utility model protection domain, and for those skilled in the art, any alternate modification make the utility model embodiment or conversion all drop in protection domain of the present utility model.
