Description

Pen capable of adapting to various refill lengths

Technical Field

The invention relates to the field of writing tools, in particular to a pen capable of adapting to various refill lengths.

Background

People can encounter pen cores with various lengths in daily life, and the single length of the pen core is only suitable for the pen core with a certain length, so that a pen suitable for the pen core length has to be purchased for many times during use.

In order to solve the above problems, as disclosed in publication No.: CN103832122A patent discloses a gel pen suitable for different long and short refills, which comprises a pen tube, a pen tail and a screw rod. When the pen works, the length of the inner space is adjusted by rotating the screw rod, so that the pen is suitable for pens with different lengths, and the device has the advantage that the length of the pen core can be adjusted. But has the following disadvantages: if a pen core with large length change is encountered in the adjusting process, the adjusting range is large, and a plurality of circles of telescopic plugs are required to be rotated, so that troubles are caused. As disclosed in publication No.: CN202144157U patent discloses a pen suitable for various refills, which comprises a pen container and a pen end. When the pen is in use, the pen end is rotated and is provided with the threaded structure, so that the internal space of the pen is adjusted, and the pen is suitable for lengths of various refills. The advantages are that: the problem of different lengths of the pen core is solved. But has the following disadvantages: the adjusting process is not attractive, the pen end can come out of the pen container, and the trouble caused by excessive rotation times in the adjusting process can be caused.

Disclosure of Invention

In order to solve the problems, the invention provides a pen capable of adapting to various lengths of pen cores, which is characterized in that when the length of the pen core needs to be switched, if the required adjusting range is large, the length increasing plate can be extended out by pulling out the upper pen tube, and the length in the pen container is increased. If the required adjusting range is very small, the adjusting can be carried out through the length adjuster, and therefore the problem that the operation is complex when the adjusting range is large is solved. And the length regulator can not extend out of the pen feeding tube in the regulating process, thereby solving the problem of attractive appearance in the regulating process.

In order to achieve the purpose, the pen capable of adapting to various refill lengths is realized by the following steps:

the structure of the pen comprises an upper pen tube, a lower pen tube and a length adjuster of the pen, the outer pen tube internally comprises threads, a circular ring baffle and a linkage rod, and the linkage rod is connected with the circular ring baffle, so that the upper pen tube and the lower pen tube are of an integral structure. The lower part of the upper pen tube is provided with a circle of clamping grooves. The lower pen tube comprises a length increasing plate, a lower pen tube clamping groove, a track plate and a linkage shaft. The length adjuster comprises a rotating shaft, a serial rod, a moving track, a threaded pipe and a bottom baffle.

The circular ring baffle is of an annular structure, namely the pen core can penetrate through the middle of the baffle, and the position of the baffle can prevent the length regulator from moving downwards continuously.

The lower end of the track plate is connected with the interior of the pen tube, so that the track plate and the pen tube are of a unified integral structure.

The track plate provides a fixed track for the movement of the linkage shaft.

The linkage shaft is connected with the length increasing plate and the linkage rod, and the three structures can move uniformly when the upper pen tube moves upwards.

The upper pen holder clamping groove and the lower pen holder clamping groove can enable the upper pen tube and the lower pen tube to be combined together.

The length adjuster is a device for finely adjusting the internal length of the penholder, and the position of the length adjuster is connected with the thread of the upper penholder.

The bottom baffle can support the refill, when length adjuster removed, can make the whole inner space of pen tube change to reach the purpose that adapts to refill length.

The rotating shaft is a device for controlling the rotation of the threaded pipe.

The movable track provides a movable track for the serial shaft, the rotating shaft can still freely move up and down in the moving process of the threaded pipe, the rotating shaft can be twisted in space in the rotating process of the user, and the problem that the appearance is not attractive due to the fact that an internal structure is exposed outside in the adjusting process can be avoided.

Detailed Description

The technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings, and it should be understood that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1, the preferred embodiment of the present invention is: the structure of the pen comprises an upper pen tube 1, a lower pen tube 10 and a length adjuster 16 of the pen, wherein the outer pen tube 1 internally comprises threads 2, a circular ring baffle 3 and a linkage rod 4, and the linkage rod 4 is connected with the circular ring baffle 3, so that the upper pen tube 1 and the lower pen tube 10 are of an integral structure. The lower part of the upper pen tube 1 is provided with a circle of clamping grooves 5. The pen dropping tube 10 comprises a length increasing plate 6, a pen dropping tube clamping groove 7, a track plate 8 and a linkage shaft 9. The length adjuster 16 includes a rotating shaft 11, a tandem rod 12, a moving rail 13, a threaded pipe 14, and a bottom barrier 15.

Principle of operation

As shown in figure 1, when a large-range pen tube internal length lengthening is required, the upper pen tube 1 is pulled out, the upper pen tube 1 is lifted upwards to enable the length increasing plate 6 to move upwards along with the linkage shaft 9 and the linkage rod 4, and a return hook is arranged above the track of the track plate 8 and used for blocking the length increasing plate 6 and the linkage shaft 9 from moving downwards. When the length needs to be adjusted back to shorten the pen tube, the upper pen tube 1 only needs to be lifted up slightly again to separate the linkage shaft 9 from the back hook, and then the upper pen tube 1 is pushed down to clamp the upper pen tube 1 back to the joint of the lower pen tube 10. When the internal length of the pen tube needs to be adjusted in a small range, the rotating shaft 11 is only required to be twisted to enable the threaded tube 14 to move until the bottom baffle 15 abuts against the pen core, and then adjustment can be completed. The threaded pipe 14 is blocked by the annular baffle 3 during the downward movement, so that the threaded pipe cannot move downwards without limitation. And the position of the rotating shaft 11 can move up and down due to the existence of the rail 13 during the adjustment, it can change its position without being moved by the screw pipe 14 during the adjustment.

While the preferred embodiments of the present invention have been illustrated and described, it will be appreciated that various changes can be made therein without departing from the spirit and scope of the invention.
