Referring to fig. 2 and 7, a pressing rod 403 integrally extends upward from the middle of the upper end surface of the knock core 4, and the pressing rod 403 passes through the catch wheel 6 and is exposed at the top of the pen holder 1 to facilitate pressing. The diameter of the pressing rod 403 is smaller than that of the body of the snap core 4, and a second step surface is arranged between the body of the snap core 4 and the pressing rod 403; the upper end of the catch wheel 6 extends towards the center to form an annular catch platform 601, the refill 2 pushes the knock core 4 upwards under the elastic force of the elastic component 3, and the knock core is stopped upwards and limited on the bottom surface of the catch platform 601 through the second step surface.

Referring to fig. 4 and 7, the pressing rod 403 is provided with two symmetrical limiting chutes 4031 along the axial direction, the annular blocking platform 601 is provided with two protrusions 602 along the inner peripheral wall corresponding to the two limiting chutes 4031, the two protrusions 602 extend into the corresponding limiting chutes 4031, and the knock core 4 is in sliding fit with the protrusions 602 through the limiting chutes 4031 thereon to limit the knock core 4 from rotating, and the knock core 4 can only move vertically up and down.

Referring to fig. 5 and 6, the outer circumferential surface of the knock-down core 4 is vertically provided with a guide track 401 connected end to end, the inner wall of the rotating wheel 5 is integrally formed with a slider 501, the slider 501 extends into the guide track 401, and the slider 501 can move unidirectionally along the guide track 401 when the knock-down core 4 is pressed.

Specifically, the press core 4 is recessed inwards along the outer peripheral surface to form a groove, and the contour shape of the groove meets the requirement of the motion track of the slider 501; in addition, the core 4 is provided with a stop block 402 which is not connected with the inner wall of the groove at the middle part of the groove, so that a guide track 401 is formed at the outer side of the stop block 402 in a circle.

Further, the guide rail 401 is provided with a home position 4011, a locking position 4012, a high extending position 4013 and a high retracting position 4014, the home position 4011 is located at the bottom of the guide rail 401, the locking position 4012 is located on the stop block 402, and the high extending position 4013 and the high retracting position 4014 are located on two sides above the locking position 4012 respectively. When the slider 501 is located at the home position 4011 (as shown in fig. 8), the pen core 2 is in a retracted state. When the knock core 4 applies a pressing force, in the process that the knock core 4 drives the pen core 2 to move downwards, the slider 501 located in the original position 4011 slides relatively along the guide track 401 (as shown in fig. 9), and the rotating wheel 5 rotates until the slider 501 reaches the high extending point 4013 (as shown in fig. 10), and in the process, the elastic component 3 is compressed to store energy; after the pressing force is released, the pen core 2 pushes the knock core 4 to move upwards under the elastic force of the elastic part 3, so that the slide block 501 falls into a locking position 4012 (shown in fig. 11) from a high extending position 4013, and the pen core 2 is in a writing state. When the knock core 4 applies pressing force again, in the process that the knock core 4 drives the pen core 2 to move downwards, the sliding block 501 located at the locking position 4012 slides relatively along the guide track 401, and the rotating wheel 5 rotates until the sliding block 501 reaches the retraction high point 4014 (as shown in fig. 12), and meanwhile, the elastic component 3 is compressed to store energy; after the pressing force is released, the pen core 2 pushes the knock core 4 to move upwards under the elastic force of the elastic part 3, so that the slider 501 slides relatively along the guide track 401 (as shown in fig. 13), and returns to the original position 4011 from the retraction high point 4014.

Still further, with continued reference to fig. 5, the stop block 402 is shaped as a downward pointing arrow, and the stop block 402 has a first tip 4023 on the left side, a second tip 4024 on the right side, a third tip 4025 on the bottom, and a V-shaped groove between the first tip and the second tip, where the tip of the V-shaped groove is located as the locking site 4012. The surface of the stopper block 402 connected between the second tip 4024 and the third tip 4025 is a first guide surface 4021, and the surface connected between the second tip 4024 and the lock position 4012 is a second guide surface 4022. The inner wall of the recessed groove of the knock core 4 has a third guide surface 4015, a fourth guide surface 4016, and a fifth guide surface 4017.

Each guide surface will be described in detail below.

Referring to fig. 5, the first guide surface 4021 is disposed to be inclined upward to a lower right side surface of the stopper 402. The first guide surface 4021 has a head end on the third tip 4025, and the first guide surface 4021 has a tail end on the second tip 4024, which is higher than the head end. It should be noted that the direction from the head end to the tail end defined in this application is the same as the direction (counterclockwise direction) in which the slider 501 moves along the guide track 401, and the same applies hereinafter. The first guide surface 4021 is disposed opposite to the home position 4011, that is, the home position 4011 can be projected vertically upward on the first guide surface 4021. It is emphasized that home 4011 is offset to the right from the vertical on which third tip 4025 is located. When pressing the thumb press 4, the thumb press 4 moves downwards for an initial distance, and the rotating wheel 5 does not rotate in the process of sliding along the guide track 401 relatively vertically, so as to ensure that the sliding block 501 can smoothly slide relatively to the first guide surface 4021 from the home position 4011, and therefore, the home position 4011 needs to be set to be shifted to the right relative to the third tip 4025. When the slider 501 slides onto the first guide surface 4021 and continues to slide relatively along the first guide surface 4021 in the following movement process, the slider 501 is pushed by the first guide surface 4021, so that the rotating wheel 5 rotates.

The third guide surface 4015 is located above the end of the first guide surface 4021 (in other words, the second tip 4024), that is, the end of the first guide surface 4021 can be projected vertically upward on the third guide surface 4015. The third guide surface 4015 is arranged to incline upward, and has a terminal end higher than the head end and a terminal end extending to the projecting high point 4013. During the downward movement of the knock core 4, the first guide surface 4021 can guide the slider 501 to the third guide surface 4015, and then the slider 501 is guided to the high protrusion point 4013 by the third guide surface 4015.

Second guide surface 4022 is located opposite to high protrusion point 4013 and below high protrusion point 4013. The second guide surface 4022 is arranged to be inclined downward, with a head end at the second tip end 4024 and a tail end extending to the locking position 4012, and the tail end of the second guide surface 4022 is lower than the head end. It is emphasized that the vertical plane of the extended high point location 4013 is offset to the left relative to the vertical plane of the second cusp 4024. After the pressing force is released, the elastic member 3 drives the pen core 2 to push the knock core 4 to move upward for an initial distance, and in this process, the rotating wheel 5 does not rotate because the rotating wheel 5 slides vertically relative to the guide rail 401, and in order to ensure that the slider 501 can smoothly slide relative to the second guide surface 4022 from the high protruding point 4013, the high protruding point 4013 needs to be set to be offset leftward relative to the second tip 4024. When the slider 501 slides onto the second guide surface 4022 and during the following movement, the relative sliding is continued along the second guide surface 4022 and guided to the lock position 4012 by the second guide surface 4022; during this sliding process, the slider 501 is pushed by the second guide surface 4022, so that the rotary wheel 5 rotates.

The fourth guide surface 4016 is provided opposite to the lock position 4012 and above the lock position 4012. The fourth guide surface 4016 is arranged to incline upward, and has a distal end higher than the head end and a distal end extending to the retraction height point 4014. It is emphasized that the vertical plane of the locking position 4012 is offset to the left compared to the vertical plane of the protruding high position 4013, and the locking position 4012 can be projected vertically upwards on the fourth guide surface 4016. When pressing press core 4 once more, press core 4 initial a distance of downstream, because runner 5 along the relative vertical slip of guide rail 401, this process runner 5 can not rotate, in order to guarantee that slider 501 can smoothly relative slip to fourth guide face 4016 by locking position 4012, consequently, need stretch out high position 4013 with locking position 4012 relatively and set up to squinting left, prevent that slider 501 from slipping back and stretching out high position 4013. When the slide block 501 slides onto the fourth guide surface 4016 and during the following movement, it continues to slide relatively along the fourth guide surface 4016 and is guided by the fourth guide surface 4016 to the retraction high-point position 4014; during this sliding, the slider 501 is pushed by the fourth guide surface 4016, so that the rotary wheel 5 rotates.

The fifth guide surface 4017 is located opposite the high retract position 4014 and below the high retract position 4014. In this embodiment, the fifth guiding surface 4017 is composed of a first inclined surface and a second inclined surface that are connected to each other, the first inclined surface and the second inclined surface are both arranged to be inclined downward, and the end of the second inclined surface extends to the original position 4011. It is emphasized that the vertical plane of the retracted high point 4014 is offset to the left compared to the vertical plane of the first tip 4023, and the retracted high point 4014 can project vertically downward on the first inclined plane. After the pressing force is released again, the elastic component 3 drives the pen core 2 to push the knock core 4 to move upwards for an initial distance, because the rotating wheel 5 slides vertically relatively along the guide track 401, the rotating wheel 5 does not rotate in the process, and in order to ensure that the slider 501 can smoothly slide relatively to the first inclined plane from the retraction high point 4014, the retraction high point 4014 needs to be set to be deviated leftwards relative to the first tip 4023, so that the first tip 4023 is prevented from blocking the slider 501. When the slider 501 slides to the first inclined surface, the first inclined surface transits to the second inclined surface, and finally the second inclined surface guides the slider 501 to the original position 4011. Of course, the fifth guide surface 4017 may be a curved surface inclined downward, and the end of the curved surface extends to the home position 4011, which can achieve the same technical effect.

It should be noted that, although there is a collision during the sliding of the slider 501 from each point to the corresponding guide surface in the guide rail 401, the collision is not enough to generate sound because the stroke of the slider 501 from each point to the corresponding guide surface is small, and each guide surface is a slope, the slider 501 falls on the corresponding guide surface and slides directly along the slope, and the speed of pressing the knock core 4 by hand is not so fast, and the knock core 4 cannot be instantaneously released by hand when releasing the knock, so that the silent effect is achieved.

Wherein, there are two guide tracks 401, and the two guide tracks 401 are distributed on the outer circumference of the knock core 4 in central symmetry. Correspondingly, the rotating wheel 5 is provided with two sliding blocks 501, and the two sliding blocks 501 correspondingly extend into the two guide tracks 401 one by one, so that the stability of each part during movement can be improved.

In addition, the core 4 is provided with two rail sliding inlets 404 along the lower end corresponding to the two guide rails 401, the rail sliding inlets 404 are in a horn shape with a large lower end and a small upper end, and the rail sliding inlets 404 are communicated with the positions of the original positions 4011 of the guide rails 401 in a one-to-one correspondence manner. During assembly, the rotating wheel 5 is placed in the pen holder 1, and the pressing core 4 is directly inserted above the rotating wheel 5, so that the sliding block 501 on the rotating wheel 5 slides to the original position 4011 along the rail sliding inlet 404, and the assembly is very convenient.

Referring to fig. 15, the sliding block 501 is a rhombus, the upper and lower vertex angles are provided with chamfers, the upper and lower vertex angles are located on the same vertical surface, and the sliding block 501 slides on each guide surface by the upper and lower vertex angles, so that the contact surface is smaller, and the sliding can be more stable. Moreover, in the process of the pen core 2 from the writing state to the retracted state, the pressing of the knock core 4 does not require the entire slider 501 to completely pass over the first tip 4023, and as long as it is ensured that after the vertex angle below the slider 501 passes over the first tip 4023, the knock core 4 is released, and the elastic member 3 drives the pen core 2 to push the knock core 4 to move upward, so that the first tip 4023 is in contact with an inclined surface of the slider 501 (as shown in fig. 14), and the slider 501 is pushed to slide along the guide track 401. Therefore, the use of the diamond-shaped slider 501 allows the guide track 401 of the knock pen 4 to have a smaller turning angle, so that the knock pen can be made thinner, and also the stroke of the movement of the pen core 2 can be reduced.

Therefore, the utility model provides a noiseless pen that presses, install press core 4 and runner 5 in pen-holder 1, be provided with guide rail 401 on the outer peripheral face of press core 4, runner 5 rotatable suit is on press core 4, and be provided with slider 501 that extends to in the guide rail 401 on runner 5, slider 501 can move to locking position 4012 and normal position 4011 along guide rail 401 when press core 4 presses, in order to realize that refill 2 stretches out or retracts in pen-holder 1, and then can not send the noise because of the collision, reach the silence effect; simultaneously, this application adopts this structural design still to have simple structure, each spare part convenient assembling, low in manufacturing cost, product stability is high and the user uses the advantage of feeling good, presses the pen moreover and also can accomplish more thinly.
