Detailed Description

The invention is further described below with reference to the accompanying drawings.

Example (b):

a self-locking pull pen as shown in fig. 1 to 8, characterized in that: comprises an inner rod 1, a movable outer cylinder 2, a rotary assembly, a pen core 7 and a spring 8. The inside lever 1 is divided into a front lever 11 and a rear lever 12. The rotating assembly is completely sleeved in the rear rod 12, the inner rod 1 is partially sleeved in the movable outer cylinder 1, the refill 7 is sleeved in the inner rod 1, the spring 8 is positioned between the front rod 11 and the refill 7, and the front rod 11 is in threaded fit connection with the rear rod 12. A limiting inner bulge 121 is arranged in the bottom end of the rear rod 12. The top of the inner protrusion 121 is provided with a plurality of isolation pillars 1211, and the isolation pillars 1211 are annularly arranged. The end of the isolation use column 1211 is provided with a use slope 12111, and a use sliding groove 1212 is provided between the two isolation use columns 1211. The rotating assembly is formed by sleeving an internal rotating piece 6 and a pushing piece 5, an extension annular table 21 is arranged in the movable outer cylinder 2, and the extension annular table 21 is matched with the pushing piece 5 through a buckling structure. The internal rotation element 6 is rotatable with respect to the pushing element 5. A plurality of internal rotation bosses 61 are annularly distributed on the outer surface of the internal rotation piece 6, internal rotation sliding grooves 62 are further arranged among the internal rotation bosses 61, and internal rotation using slopes 612 and separating slopes 611 are arranged on the internal rotation bosses 61. The outer surface of the pushing piece 5 is provided with anti-rotation bosses 51, anti-rotation chutes 52 are also arranged among the anti-rotation bosses 51, and the top end of the pushing piece is also provided with an adjusting slope 53.

The rotation-preventing bosses 51 and the inward rotation bosses 61 are movable in the use slide slots 1212, and the isolation use columns 1211 are movable in the rotation-preventing slide slots 52 and the inward rotation slide slots 62. The adjustment ramp 53 and the use ramp 12111 are in contact engagement with the pronation use ramp 612 and the disengagement ramp 611. The above-mentioned contact engagement of the regulation slope 53 and the inward rotation use slope 612 and the disengagement slope 611 assists in changing the engagement relationship of the inward rotation use slope 612 and the disengagement slope 611 and the use slope 12111.

When no external force is interfered, the inward-rotation boss 61 is in the use sliding groove 1212, and is in a non-use state, and the pen core is kept in a state of being retracted into the inner rod 1.

When the inward rotation boss 61 collides with the isolated use column 1211, the inward rotation boss 61 is not in the use sliding groove 1212, the pen is in a use state, and the pen core is exposed out of the inner rod 1.

If the internal rotation boss 61 is disposed in the usage chute 1212, the inner rod 1 is squeezed to indirectly squeeze the pushing member 5, the adjustment slope 53 continuously collides with the internal rotation usage slope 612, at this time, the internal rotation usage slope 612 and the adjustment slope 53 are in a half-contact state, and the internal rotation member 6 is forced to move upwards continuously, after the internal rotation boss 61 is out of the engagement range of the usage chute 1212, the internal rotation usage slope 612 is completely engaged with the adjustment slope 53, the internal rotation member 6 is forced to rotate in a certain range, so that the internal rotation usage slope 612 and the usage slope 12111 are in half-contact, when the squeezing of the inner rod 1 is released, the inner rod 1 is reset by the force of the spring 8, but at this time, the internal rotation usage slope 612 and the usage slope 12111 are in half-contact, so that the internal rotation member 6 is directly rotated, and the internal rotation boss 61 is clamped at the top end of the isolated usage column 1211, the internal rotation piece 6 can also lead the pushing piece 5 and the inner rod 1 not to be completely reset, at the moment, the pen core is in a pen core using state, the pen core point keeps a state of exposing the inner rod 1,

at this time, if the inner rod 1 is further pressed to indirectly press the pushing member 5, the adjusting slope 53 at this moment continuously collides with the disengaging slope 611, at this time, the adjusting slope 53 and the disengaging slope 611 are in a half-contact state, and the inner rotating member 6 is forced to move upwards continuously, after the inner rotating boss 61 is out of the engagement range of the use sliding groove 1212, the disengaging slope 611 is completely engaged with the adjusting slope 53, so that the inner rotating member 6 is forced to rotate in a certain range, the inner rotating use slope 612 is disengaged from the collision of the use slope 12111, the disengaging slope 611 is in half-contact with the use slope 12111, when the inner rod 1 is pressed by releasing, the inner rod 1 is reset by the acting force of the spring 8, but the disengaging slope 611 is already in half-contact with the use slope 12111, so that the inner rotating member 6 is directly rotated, and the inner rotating boss 61 is disengaged from the collision with the isolated use column 1211, the pen core slides into the using sliding groove 1212 again, the pushing piece 5 and the inner rod 1 are released, and the pen core can be completely reset, and at the moment, the pen core is in a non-using state, and the pen core point is kept in a state of being retracted into the inner rod 1.

When the inner rod 1 is retracted into the movable outer cylinder 2 to the maximum extent, the distance between the opening of the movable outer cylinder 2 and the core outlet of the front rod 11 should be controlled to be 1-80 mm, so as to ensure that the jaw of a user can clamp the movable outer cylinder 2.

In order to facilitate carrying, the pen is prevented from being extruded from the outside to cause refill discharge in the carrying process, so that the carrying environment is polluted, and the extension ring platform 21 is further provided with a self-locking buckle 211. The rear rod 12 is further provided with a sliding straight groove 122 and a self-locking groove 123 which are matched with the self-locking buckle 211. The length of the straight sliding groove 122 is at least equal to or more than the distance between the pen core retracting state and the pen core ejecting state. The self-locking groove 123 is tightly attached to the sliding straight groove 122, and is specifically located at the opening of the sliding straight groove 122. When the inner rod 1 and the movable outer cylinder 2 normally slide up and down, the self-locking buckle 211 slides in the slideway straight groove 122. When self-locking is needed, the movable outer cylinder 2 or the inner rod 1 is rotated in a core retracting state, so that the self-locking buckle 211 enters the self-locking groove 123 from the sliding straight groove 122 in a switching manner, the self-locking buckle 211 cannot slide up and down under the limitation of the self-locking groove 123, and the sliding relation between the inner rod 1 and the movable outer cylinder 2 is locked.

In order to facilitate faster self-locking, the self-locking effect can be realized no matter in left-handed rotation or right-handed rotation. The number of the self-locking grooves 123 is twice that of the sliding straight grooves 122, and the self-locking grooves 123 are provided on both left and right sides of the sliding straight grooves 122.

In order to prevent the self-locking buckle 211 from entering the self-locking groove 123 by mistake in the normal use process to cause the card owner in the use process, an anti-falling boss 124 is further arranged between the self-locking groove 123 and the sliding straight groove 122. The vertical height of the anti-slip boss 124 is lower than that of the opening at the end of the self-locking groove 123 of the rear rod 12.

In order to prevent the internal rotation member 6 from falling off from the rear rod when the refill is replaced, and thus to prevent the components from being lost, the internal rotation member 6 is further provided with an engaging ring protrusion 63. The pushing piece 5 is also provided with the inner rotating piece 6 which is clamped and connected with the pushing piece 5 through the clamping inner platform 56 and the clamping ring protrusion 63.

In order to meet the requirements of different consumers, the original snap fit can be replaced by a threaded or magnetic attraction mode between the extension ring platform 21 and the pushing piece 5.

As the normal extension range of the product, a pen clip and/or a skin-scrubbing eraser can be additionally arranged on the movable outer cylinder 3. The inner rod 1 can also be provided with a pen holding sleeve 13.

The core drawing and core collecting operation method comprises the following steps:

the jaw clamps the movable outer cylinder 2, then clamps the front end of the inner rod 1 by using the forefinger and the middle finger, and forcibly contracts the inner rod 1 to move towards the direction of the rotary combined piece, thereby realizing the quick switching of core withdrawing and core discharging.

The self-locking method comprises the following steps:

the rear rod is held by one hand, the movable outer cylinder is rotated by the other hand, the self-locking buckle 211 of the movable outer cylinder is switched from the sliding straight groove 122 to enter the self-locking groove 123, and then the hand is released.

The unlocking method comprises the following steps:

the rear rod is held by one hand, the movable outer cylinder is reversely rotated towards the direction opposite to the locking direction by the other hand, and the self-locking buckle 211 is screwed out of the self-locking groove 123 and enters the sliding straight groove 122.
