Description

Technical Field

[0001] The invention relates to a pen, in particular to a self-locking lifting pen. Background Art

[0002] The traditional click pens on the market today all control the ejection and retraction of the pen core by operating the pen with the tail. This method is rather cumbersome. Although it has made great progress and improvement compared to the traditional capped pens, the operation method remains unchanged in the 21st century, and there should be a better operation method to replace it, just as it replaced the traditional capped pens. Summary of the invention

[0003] The purpose of the invention is to provide a self-locking lifting pen as the existing operation method is relatively complicated.

[0004] In order to achieve the above-mentioned object of the invention, the present invention adopts the following technical solutions:

[0005] A self-locking lifting pen, characterized in that it comprises an inner rod, a movable outer tube, a rotating assembly, a pen core and a spring; the inner rod is divided into a front rod and a rear rod; the rotating assembly is completely sleeved in the rear rod, the inner rod is partially sleeved in the movable outer tube, the pen core is sleeved in the inner rod, the spring is located between the front rod and the pen core, and the front rod and the rear rod are threadedly connected; a limiting inner convex is provided at the bottom end of the rear rod; a plurality of isolation use columns are provided at the top end of the limiting inner convex, and the isolation use columns are all distributed in a ring shape; a use slope is provided at the end of the isolation use column, so that A use slide groove is provided between the two isolation use columns; the rotating assembly is composed of an inner rotating member and a push member sleeved together, an extension ring is provided in the movable outer cylinder, and the extension ring and the push member are matched through a snap-fit ​​structure; the inner rotating member can rotate relative to the push member; a plurality of inner rotating bosses are annularly distributed on the outer surface of the inner rotating member, inner rotating slide grooves are also provided between the inner rotating bosses, and an inner rotating use slope and a disengagement slope are provided on the inner rotating bosses; an anti-rotation boss is provided on the outer surface of the push member, an anti-rotation slide groove is also provided between the anti-rotation bosses, and an adjustment slope is also provided on the top;

[0006] The anti-rotation boss and the inward rotation boss can both be movably slidable in the use slide groove, and the isolation use column can be movably slidable in the anti-rotation slide groove and the inward rotation slide groove; the adjustment slope and the use slope can both be in contact with the inward rotation use slope and the disengagement slope; the contact and cooperation between the adjustment slope and the inward rotation use slope and the disengagement slope assists in changing the cooperation relationship between the inward rotation use slope, the disengagement slope and the use slope;

[0007] When there is no external force interference, the inner rotating boss is located in the use slide groove, which means it is not in use, and the pen core remains in the state of being retracted into the inner rod;

[0008] When the inwardly rotating boss and the isolation use column collide with each other, so that the inwardly rotating boss is not in the use slide groove, it is in the use state, and the pen core is in the state of exposing the inner rod;

[0009] When the inner rod is released from the engagement range of the slide groove, the inner rod is fully engaged with the adjusting slope, forcing the inner rod to rotate by a certain amplitude, so that the inner rod is semi-contacted with the engagement slope again. When the engagement is released, the inner rod is reset due to the action of the spring, but at this time the inner rod is semi-contacted with the engagement slope. Therefore, the inner rod will be further rotated, so that the inner rod is stuck at the top end of the isolation column, and the inner rod will also make it impossible for the pushing member and the inner rod to be completely reset. At this time, the refill is in use, and the refill tip remains exposed from the inner rod.

[0010] When the inner rod is squeezed again to indirectly squeeze the pushing member, the adjusting slope will continue to contact the disengaging slope. At this time, the adjusting slope and the disengaging slope are in semi-contact state and force the inner rotating member to move upward continuously. When the inner rotating boss is out of the matching range of the use slide groove, the disengaging slope is fully matched with the adjusting slope, forcing the inner rotating member to rotate to a certain extent, so that the inner rotating use slope is out of the conflict with the use slope, and the disengaging slope is semi-contacted with the use slope again. When the squeezing of the inner rod is released, the inner rod will be reset due to the force of the spring, but at this time the disengaging slope has been semi-contacted with the use slope. Therefore, it will directly cause the inner rotating member to rotate further, so that the inner rotating boss is out of the conflict with the isolation use column and slides into the use slide groove again, and the pushing member and the inner rod are also released and can be fully reset. At this time, the pen core is not in use, and the pen core tip remains retracted in the inner rod.

[0011] When the inner rod is retracted into the movable outer tube to the maximum extent, the distance between the opening of the movable outer tube and the core outlet of the front rod should be controlled between 1 and 80 mm to ensure that the user's thumb and mouth can clamp the movable outer tube;

[0012] The operation method of core extraction and core collection is as follows:

[0013] Hold the movable outer cylinder with the jaws of the thumb, then hold the front end of the inner rod with the index and middle fingers, and forcefully contract the inner rod to move it in the direction of the rotating assembly, thereby achieving rapid switching between core collection and core extraction.

[0014] Preferably: a self-locking buckle is also provided on the extension ring platform; a sliding straight groove and a self-locking groove matching the self-locking buckle are also provided on the rear rod; the length of the sliding straight groove is at least greater than the distance between the refilled state and the unfilled state; the self-locking groove is close to the sliding straight groove and is specifically located at the opening of the sliding straight groove; when the inner rod and the movable outer cylinder slide up and down normally, the self-locking buckle slides in the slide straight groove; and when self-locking is required, in the refilled state, the movable outer cylinder or the inner rod is rotated so that the self-locking buckle switches from the sliding straight groove to the self-locking groove, and the self-locking buckle is restricted by the self-locking groove and cannot slide up and down, thereby locking the sliding relationship between the inner rod and the movable outer cylinder.

[0015] As a preferred embodiment: the number of the self-locking grooves is twice that of the sliding straight grooves, and the left and right sides of the sliding straight grooves are both provided with self-locking grooves;

[0016] Preferably, an anti-slip boss is provided between the self-locking groove and the sliding straight groove; the vertical height of the anti-slip boss is lower than the vertical height of the opening of the self-locking groove end of the rear rod.

[0017] As a preference, a locking ring convex is further provided on the inner rotating member; and a locking inner platform of the pushing member is also provided, wherein the inner rotating member and the pushing member are locked and connected via the locking inner platform and the locking ring convex.

[0018] As a preference, threads or magnetic attraction may be used between the extension ring and the pusher to replace the original snap fit.

[0019] As a further preferred embodiment, a pen clip and / or an erasable eraser may be added to the movable outer tube.

[0020] As a further preference: a pen grip cover may also be provided on the inner rod.

[0021] Compared with the prior art, the above technical solution has the following beneficial effects:

[0022] 1. The traditional operation method has been changed. The operation method is changed to a writing posture to operate the core ejection and core collection. The operation concept of simply picking up the core to eject the core and collecting the core after writing replaces the traditional tail pressing operation method.

[0023] Second, it has a better self-locking effect. Through a simpler self-locking structure, it is easier to produce and manufacture. At the same time, it has a better self-locking effect and avoids polluting the carrying environment.

[0024] 3. Based on the existing click pens, this new operating method is realized by using simple components and extending the movable outer tube; the factory's familiarity process with the new structure is skipped, and this product with a mature and stable old structure and a new operating method can be produced quickly and stably; it can quickly and stably replace traditional click pens.

[0033] The present invention is further described below in conjunction with the accompanying drawings.

[0034] Example:

[0035] like Figures 1 to 8The self-locking lifting pen shown is characterized in that it comprises an inner rod 1, a movable outer tube 2, a rotating assembly, a pen core 7 and a spring 8. The inner rod 1 is divided into a front rod 11 and a rear rod 12. The rotating assembly is completely sleeved in the rear rod 12, the inner rod 1 is partially sleeved in the movable outer tube 1, the pen core 7 is sleeved in the inner rod 1, the spring 8 is located between the front rod 11 and the pen core 7, and the front rod 11 and the rear rod 12 are threadedly connected. A limiting inner protrusion 121 is provided at the bottom end of the rear rod 12. A plurality of isolation use columns 1211 are provided at the top of the limiting inner protrusion 121, and the isolation use columns 1211 are all distributed in a ring shape. A use slope 12111 is provided at the end of the isolation use column 1211, and a use slide 1212 is provided between the two isolation use columns 1211. The rotating assembly is composed of an inner rotating member 6 and a pusher 5, and an extension ring 21 is provided in the movable outer cylinder 2. The extension ring 21 and the pusher 5 are matched by a snap-fit ​​structure. The inner rotating member 6 can rotate relative to the pusher 5. A plurality of inner rotating bosses 61 are distributed in an annular shape on the outer surface of the inner rotating member 6, and inner rotating grooves 62 are provided between the inner rotating bosses 61. The inner rotating bosses 61 are provided with an inner rotating use slope 612 and a disengagement slope 611. The pusher 5 is provided with an anti-rotation boss 51 on its outer surface, and an anti-rotation groove 52 is provided between the anti-rotation bosses 51, and an adjustment slope 53 is provided at the top.

[0036] The anti-rotation boss 51 and the internal rotation boss 61 can both slide movably in the use slot 1212, and the isolation use column 1211 can slide movably in the anti-rotation slot 52 and the internal rotation slot 62. The adjustment slope 53 and the use slope 12111 can both contact and cooperate with the internal rotation use slope 612 and the separation slope 611. The contact and cooperation between the adjustment slope 53 and the internal rotation use slope 612 and the separation slope 611 assists in changing the cooperation relationship between the internal rotation use slope 612 and the separation slope 611 and the use slope 12111.

[0037] When there is no external force interference, the inwardly rotating boss 61 is located in the use slide groove 1212, which means it is in a non-use state, and the pen core remains in a state of being received in the inner rod 1.

[0038] When the inwardly rotating boss 61 and the isolating use column 1211 collide with each other, so that the inwardly rotating boss 61 is not in the use slide groove 1212, it is in the use state, and the pen core is in a state of exposing the inner rod 1.

[0039] If the inner rotation boss 61 is placed in the use slot 1212, the inner rod 1 is squeezed to indirectly squeeze the pusher 5, and the adjustment slope 53 will continue to resist the inner rotation use slope 612. At this time, the inner rotation use slope 612 and the adjustment slope 53 are in a semi-contact state, and the inner rotation member 6 is forced to move up continuously. When the inner rotation boss 61 is out of the matching range of the use slot 1212, the inner rotation use slope 612 is completely matched with the adjustment slope 53, and the inner rotation member 6 is forced to rotate to a certain extent, so that the inner rotation use The slope 612 is semi-contacted with the use slope 12111. When the inner rod 1 is squeezed, the inner rod 1 is reset due to the force of the spring 8. However, at this time, the inward rotation use slope 612 is semi-contacted with the use slope 12111. Therefore, the inner rotating member 6 is further rotated, so that the inward rotation boss 61 is stuck on the top of the isolation use column 1211. The inner rotating member 6 also makes it impossible for the pusher 5 and the inner rod 1 to be completely reset. At this time, the pen core is in use, and the tip of the pen core remains exposed from the inner rod 1.

[0040] At this time, if the inner rod 1 is squeezed again to indirectly squeeze the pushing member 5, the adjusting slope 53 at this moment will continue to resist the disengaging slope 611. At this time, the adjusting slope 53 and the disengaging slope 611 are in a semi-contact state, and the inner rotating member 6 is forced to move up continuously. When the inner rotating boss 61 is out of the matching range of the using slide groove 1212, the disengaging slope 611 is fully matched with the adjusting slope 53, and the inner rotating member 6 is forced to rotate to a certain extent, so that the inner rotating using slope 612 is out of the conflict with the using slope 12111, and the disengaging slope 611 is in a semi-contact state with the inner rotating boss 61. The use slope 12111 is semi-contacted. When the squeeze on the inner rod 1 is released, the force of the spring 8 will cause the inner rod 1 to reset. However, at this time, the disengagement slope 611 has been semi-contacted with the use slope 12111. Therefore, it will directly cause the inner rotating member 6 to further rotate, so that the inner rotating boss 61 is separated from the interference with the isolation use column 1211 and slides into the use slide groove 1212 again, and the push member 5 and the inner rod 1 are also released and can be completely reset. At this time, the pen core is not in use, and the pen core tip remains retracted in the inner rod 1.

[0041] When the inner rod 1 is retracted into the movable outer tube 2 to the maximum extent, the distance between the opening of the movable outer tube 2 and the core outlet of the front rod 11 should be controlled between 1 and 80 mm to ensure that the user's thumb and mouth can clamp the movable outer tube 2.

[0042] In order to facilitate carrying and ensure that the pen will not be squeezed out by the outside world during carrying, thereby polluting the carrying environment, a self-locking buckle 211 is also provided on the extension ring platform 21. The rear rod 12 is also provided with a sliding straight groove 122 and a self-locking groove 123 that match the self-locking buckle 211. The length of the sliding straight groove 122 is at least the distance between the refill state and the refill state. The self-locking groove 123 is close 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 slide up and down normally, the self-locking buckle 211 slides in the slide straight groove 122. When self-locking is required, in the core-retracted state, the movable outer cylinder 2 or the inner rod 1 is rotated so that the self-locking buckle 211 switches from the sliding straight groove 122 to the self-locking groove 123. The self-locking buckle 211 is restricted by the self-locking groove 123 and cannot slide up and down, thereby locking the sliding relationship between the inner rod 1 and the movable outer cylinder 2.

[0043] In order to facilitate faster self-locking, the self-locking effect can be achieved regardless of left or right rotation. The number of the self-locking grooves 123 is twice that of the sliding straight grooves 122, and the left and right sides of the sliding straight grooves 122 are both provided with self-locking grooves 123.

[0044] In order to prevent the self-locking buckle 211 from mistakenly entering the self-locking groove 123 during normal use, resulting in the main body being stuck during use, an anti-slip boss 124 is further provided between the self-locking groove 123 and the sliding straight groove 122. The vertical height of the anti-slip boss 124 is lower than the vertical height of the opening of the self-locking groove 123 end of the rear rod 12.

[0045] In order to prevent the inner rotating member 6 from falling off from the rear rod when replacing the refill, resulting in the loss of the component, the inner rotating member 6 is also provided with a snap ring protrusion 63. The snap inner platform 56 of the pusher 5 is also provided with the inner rotating member 6 and the pusher 5 are snap-connected through the snap inner platform 56 and the snap ring protrusion 63.

[0046] In order to meet the needs of different consumers, the extension ring 21 and the pusher 5 may also be connected by threads or magnetic attraction instead of the original snap fit.

[0047] As a normal expansion range of the product, a pen clip and / or an erasable eraser can be added to the movable outer tube 3. A pen grip cover 13 can also be provided on the inner rod 1.

[0048] The operation method of core extraction and core collection is as follows:

[0049] Hold the movable outer cylinder 2 with the jaws, then hold the front end of the inner rod 1 with the index and middle fingers, and forcefully retract the inner rod 1 to move it toward the direction of the rotating assembly, thereby realizing a rapid switch between core collection and core extraction.

[0050] The self-locking method is:

[0051] Grasp the rear rod with one hand and rotate the movable outer cylinder with the other hand to switch the self-locking buckle 211 from the sliding straight groove 122 to the self-locking groove 123, and then release the hand.

[0052] The unlocking method is:

[0053] Grasp the rear rod with one hand, and use the other hand to rotate the movable outer tube in the opposite direction of the locking direction, so as to rotate the self-locking buckle 211 out of the self-locking groove 123 and enter the sliding straight groove 122.
