As shown in FIG. 1 to FIG. 4 , the utility model provides a decompression device for a pen, characterized in that the decompression device for a pen comprises: a pen 10, wherein a pen tip 20 and a pen cap 30 for protecting the pen tip are provided at the front end of the pen 10;

A prism 21 is provided around the top of the pen tip 20;

The pen cap 30 is provided with a shell 31, a lock cover 32 and a decompression device 33 built into the shell;

The decompression device 33 is provided with a moving shaft 330, a spring 331, a moving wheel 332, a fixed wheel 333, and a fixed shaft 334. One end of the moving shaft 330 is connected to the moving wheel 332. The teeth of the moving wheel 332 match the teeth of the fixed wheel 333. The fixed wheel 333 is inserted into the fixed shaft 334. One end of the fixed shaft 334 is embedded in the lock cover 32. The spring 331 is sleeved on the moving shaft 330 and can only move on the moving shaft.

Specifically, the movable shaft 330 is provided with a movable shaft groove 3301, and the inner wall of the movable shaft groove 3301 is provided with a wire groove 3302, and the wire groove 3302 engages with the prism 21, so that the pen tip 20 clamps the movable shaft 330, and the movable shaft 330 cannot be separated from the pen tip and rotated. When an external force acts on the pen cap, the pen cap 30 can be separated from the pen tip. The movable shaft 330 is provided with a movable shaft coil 3303, and the width and diameter of the movable shaft coil 3303 are larger than the width and diameter of the movable shaft, and the pen cap 30 is provided with a through hole 311, and the inner wall of the through hole 311 is provided with a boss 312, in order to clamp the movable shaft coil 3303 and prevent the movable shaft 330 from being separated from the pen cap 30. The moving shaft 330 is provided with a moving shaft prism 3304. In order to lock the moving wheel 332, a through hole is provided in the middle of the moving wheel 332. The shape of the through hole is consistent with the shape of the moving shaft prism 3304. Therefore, the moving wheel is inserted into the moving shaft prism and can only slide up and down along the moving shaft prism, but cannot rotate. The moving shaft 330 is provided with a moving shaft connecting groove 3305, the fixed shaft 334 is provided with a slide post 3341, and the locking cover 32 is provided with a thread 321. The locking cover is locked at the tail of the pen cap through the thread 321, and the tail end of the fixed shaft is partially or completely embedded in the locking cover 32 to prevent the fixed shaft from detaching from the pen cap. The slide post 3341 is embedded in the moving shaft connecting groove and can only rotate in the moving shaft connecting groove, but cannot detach.

The fixed shaft 334 is provided with a prism ring 3342, and its width diameter is larger than the width diameter of the fixed shaft. A through hole is provided in the middle of the fixed wheel 333, and the shape of the through hole is consistent with the shape of the prism ring 3342. Therefore, the fixed wheel is inserted into the prism ring of the fixed shaft and can only slide up and down but cannot rotate. Because the tail end of the fixed shaft is in contact with the lock cover 32, and the top sliding column 3341 is embedded in the moving shaft connecting groove 3305, the fixed wheel cannot move in any direction.

The spring is sleeved in the middle of the moving shaft, and the two ends are respectively in contact with the moving shaft coil 3303 and one end of the moving wheel, thereby locking the position of the spring. The teeth of the moving wheel 332 and the fixed wheel 333 can be engaged with each other.

Therefore, when the pen holder is held and the pen cap is rotated, the prism 21 provided on the pen tip 20 is embedded in the groove 3301 of the moving shaft and is buckled with the wire groove 3302, thereby locking the moving shaft 330, and the locking cover 32 is provided with a thread 321, which is used to lock the pen cap, and the fixed shaft part is embedded in the locking cover, and as the pen cap rotates, because the fixed wheel 333 is inserted into the fixed shaft prism ring 3342, the fixed wheel is locked on the fixed shaft, so that as the pen cap rotates, when the external force acts on the fixed wheel, the fixed wheel teeth are separated from the teeth of the moving wheel. At this time, the moving wheel receives the force of the fixed wheel and slides downward. At this time, the spring generates an elastic restoring force acting on the moving wheel, forcing the moving wheel to slide upward, and the moving wheel teeth and the fixed wheel teeth are engaged again. When engaging, they collide and make a snapping sound, and because the teeth between the fixed wheel and the moving wheel are of the same size and number, when the pen cap is continuously rotated, the sound emitted has a rhythmic sense.

In some embodiments, the moving shaft 330 is respectively provided with a moving shaft groove 3301, a moving shaft coil 3303, a moving shaft prism 3304, and a moving shaft connecting groove 3305. The moving shaft groove 3301 is provided with a wire groove 3302 inside, which is snapped with the prism 21. The moving shaft coil 3303 is arranged in the middle of the moving shaft 330, and the moving shaft prism 3304 is snapped with the moving wheel 332.

Specifically, the wire groove 3302 is for snapping with the prism 21 provided on the pen tip 20, thereby locking the movable shaft 330 on the pen tip 20 and preventing it from rotating with the pen cap. When writing is required, the pen tip and the pen cap can be separated by external force. The movable shaft coil 3303 cooperates with the boss 312 provided on the inner wall of the through hole 311 of the outer shell 31, thereby locking the movable shaft 330 in the through hole 311 of the pen cap and preventing it from detaching from the pen cap 30. The movable shaft prism 3304 is consistent in shape with the middle through hole of the moving wheel, so the moving wheel is inserted into the movable shaft prism and cannot rotate but can only move up and down. The movable shaft connecting groove 3305 accommodates the sliding column 3341 provided on the fixed shaft, and the sliding column 3341 can only rotate in the movable shaft connecting groove but cannot slide up and down.

In some embodiments, the fixed shaft 334 is provided with a sliding column 3341 , which is embedded in one end of the driving shaft and can rotate. The fixed shaft 334 is provided with a prismatic ring 3342 , which is locked with the fixed wheel 333 .

Specifically, the outer shape of the prism ring 3342 is consistent with the shape of the middle through hole of the fixed wheel. When the fixed wheel is inserted into the prism ring 3342, it cannot rotate, and the lock cover 32 is fixed to the tail end of the pen cap by means of the thread 321, and the tail end of the fixed shaft is embedded in the lock cover so that one end of the fixed wheel abuts against the lock cover and cannot move up and down, because the teeth of the fixed wheel are always in contact with the teeth of the moving wheel. The sliding column 3341 is embedded in the moving shaft connection groove 3305 and can only rotate but not move up and down.

In some embodiments, the housing 31 is provided with a through hole 311 , and the through hole 311 is provided with a boss 312 in order to define the moving axis.

Specifically, the decompression device is always built into the through hole 311 and cannot be separated. The boss 312 locks the movable shaft so that the movable shaft cannot be separated from the pen cap, and the tail end of the pen cap is locked by the locking cover.

In some embodiments, the locking cover 32 is provided with a thread 321 for locking at the tail of the pen cap.

Specifically, since the locking cover locks the rear end of the pen cap, and the fixed shaft 334 is partially embedded in the locking cover 32, when the pen cap rotates, the fixed shaft 334 is driven to rotate, thereby driving the fixed wheel 333 to rotate.

In summary, the utility model provides a decompression device for a pen, comprising: a pen 10, wherein a pen tip 20 and a pen cover 30 for protecting the pen tip are provided at the front end of the pen 10; a prism 21 is provided on the circumferential side of the top end of the pen tip 20; the pen cover 30 is provided with a shell 31, a locking cover 32 and a decompression device 33 built into the shell; the decompression device 33 is provided with a moving shaft 330, a spring 331, a moving wheel 332, a fixed wheel 333, and a fixed shaft 334, wherein one end of the moving shaft 330 is connected to the moving wheel 332, the teeth of the moving wheel 332 match the teeth of the fixed wheel 333, the fixed wheel 333 is sleeved into the fixed shaft 334, one end of the fixed shaft 334 is embedded in the locking cover 32, and the spring 331 is sleeved on the moving shaft 330 and can only move on the moving shaft.

With the above design, when you hold the pen and turn the pen cap, the prism at the pen tip locks the moving shaft of the pen cap, and the fixed shaft rotates with the pen cap, thereby driving the fixed wheel to match the moving wheel.
