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 silent pressing pen provided by the utility model comprises an outer sleeve 10, an inner sleeve 20, a direct-acting driving piece 30, a pen cap 50 and a spring. A cap 50 extends from one end of the outer sleeve 10. The inner sleeve 20 is connected inside the outer sleeve 10 near the end of the cap 50 from which it protrudes. Preferably, the inner sleeve 20 and the outer sleeve 10 are interference fit. The direct-acting driving piece 30 is arranged in the inner sleeve 20, one end of the direct-acting driving piece is connected with the pen cap 50, and the other end of the direct-acting driving piece is connected with the pen core. Preferably, the cap 50 is a clearance fit with the inner sleeve 20 and the direct drive 30. The pressing pen also comprises a pen nib 40, and the pen nib 40 is in threaded connection with the outer sleeve 10. Preferably, an anti-slip rubber sleeve 60 is further disposed outside the nib 40 to increase friction force, so that the user can hold the pen conveniently and the writing is more comfortable.

As shown in fig. 2, 3, 4 and 5, the linear motion driving member 30 is provided with a roller 31, and the roller 31 protrudes in a vertical direction of the movement direction of the pen core. A first curve 11 is arranged on the outer sleeve 10 in a surrounding manner, and a second curve 21 is arranged on the inner sleeve 20 in a surrounding manner; a gap for accommodating the roller 31 to extend is formed between the first curve 11 and the second curve 21, the cap 50 is pressed, and the cap 50 drives the direct-acting driving part 30 to move, so that the roller 31 moves in the gap, and the pen core is driven to stretch and retract.

Referring specifically to fig. 4, the gap formed by the first curve 11 and the second curve 21 includes a first protrusion, a second protrusion, a third protrusion, and a fourth protrusion. The first protrusion and the third protrusion protrude towards the pen cap, and the second protrusion and the fourth protrusion protrude towards the pen holder. Pressing the pen cap 50, the roller 31 moves from the first projection to the second projection, and the pen core extends; when the cap 50 is loosened, the roller 31 moves from the second projection to the third projection, the refill retracts, but a part of the refill is still exposed out of the outer sleeve 10, and then the pressing pen provided by the utility model can be used for writing. After writing, the pen cap 50 is pressed, the roller 31 moves from the third projection to the fourth projection, and the pen core extends out; when the cap 50 is loosened, the roller 31 moves from the fourth bulge to the first bulge, the refill is completely retracted into the outer sleeve 10, and the roller 31 is always kept in the first bulge.

Preferably, two rollers 31 are provided, symmetrically disposed on both sides of the direct acting driving member 30. The refill is sleeved with a spring to realize the resetting of the refill.

The using method of the utility model comprises the following steps: the pen cap 50 is pressed to drive the direct-acting driving piece 30 to move in a direction far away from the pen cap 50, the spring is compressed, and meanwhile, the roller 31 moves along the gap and rotates under the constraint of the first curve 11; when the pen cap 50 is loosened, the spring is released, the linear driving part 30 which rotates for a certain angle moves towards the direction close to the pen cap 50, the roller moves along the gap, rotates under the constraint of the second curve 21 and is limited, and the pen core extends out. Thereafter, the pressing and releasing operation is performed again, the pen core retracts, and the knock pen returns to the initial state. In the above steps, the linear driving member 30 rotates 180 degrees to complete a cycle of extending and retracting the pen core.

Preferably, the outer sleeve 10 is provided with a notch 12, the inner sleeve 20 is provided with a projection 22, and the projection 22 is in snap fit connection with the notch 12, so that the inner sleeve 20 is connected in the outer sleeve 10. The outer side of the outer sleeve 10 is provided with a pen clip 13 for clamping.

As shown in fig. 2 and 6, the outer sleeve 10 is provided with an outer sleeve joint tooth 14, and the nib 40 is provided with a nib joint tooth 41, so that the outer sleeve 10 and the nib 40 can be connected in a screw-fit manner.

While the present invention has been described in detail with reference to the preferred embodiments, it should be understood that the above description should not be taken as limiting the utility model. Various modifications and alterations to this invention will become apparent to those skilled in the art upon reading the foregoing description. Accordingly, the scope of the utility model should be determined from the following claims.
