DETAILED DESCRIPTION
[0022] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.
[0023] See also Figure 1-5 The present embodiment relates to a recyclable ink-refilling gel pen, comprising a pen body 101 and a pen cap 102 and a pen head 103 connected at both ends thereof, constituting a gel pen body 100, the gel pen body 100 further comprising an ink cartridge 104, the ink cartridge 104 being provided with an ink outlet head 1041, the pen cap 102 and the adapted ink cartridge 104 being rotatably arranged in a mounting groove 1 provided at one end of the pen body 101, the mounting groove 1 being provided with a through hole 11 of a size adapted to the end of the ink outlet head 1041 and being slidably provided with a The connecting component 2 includes a connecting seat 21 placed below the mounting groove 1 inside the pen barrel 101 and a pressure plate 22 placed above the mounting groove 1. The connecting seat 21 is surrounded by a plurality of through grooves 211 at corresponding positions along the periphery of the through hole 11, and is provided with multiple groups of connecting rods 23 which are passed through the mounting groove 1 and connected to the upper pressure plate 22. The connecting rod 23 is clamped on the mounting groove 1 by an adaptable compression spring 24 sleeved on the outside, and a card slot 221 of a size that adapts to the through hole 11 is opened on the pressure plate 22.
[0024] Specifically in this embodiment, when using this gel pen structure, please refer to Figure 1-3 As shown, the pressure plate 22 above the mounting groove 1 and the connecting seat 21 below the said mounting groove 1 slide upwards under the action of the adapting compression spring 24 provided on the outer side of the corresponding connecting rod 23. The seat body of the said connecting seat 21 seals the bottom of the through hole 11. The said pen cap 102 and the pen body 101 can be rotatably connected and fixed by an adapting threaded structure. At the same time, the said adapting pen cap 102 structure rotatably provided on the pen body 101 does not contact the pressure plate 22 in the mounting groove 1 during the rotation process. When ink needs to be added, the pen cap 102 above the mounting groove 1 on the pen body 101 can be removed. The said adapting ink cartridge 104 can be rotatably provided on the corresponding position of the pen body 101 through the adapting threaded structure provided on the periphery of its ink outlet head 1041. The said ink cartridge 104 and its adapting ink outlet head 1041 structure can be seen in FIG. Figure 4As shown in FIG, the ink cartridge 104 is rotated, see Figure 5 As shown, the ink cartridge 104 drives the ink outlet head 1041 to move downward during the rotation process, and the adapting structure at the head end of the ink outlet head 1041 first penetrates the card slot 221 on the pressure plate 22 and enters the through hole 11 of the mounting slot 1. At the same time, as the ink outlet head 1041 moves, it contacts the pressure plate 22 and drives the pressure plate 22 downward under the card setting of the card slot 221. The connecting seat 21 moves downward in the pen barrel 101 through the connecting rod 23, thereby separating the connecting seat 21 from the bottom of the through hole 11 on the mounting slot 1, thereby opening the through hole 11. The ink in the ink cartridge 104 can reach the through hole 11 of the mounting slot 1 through the ink outlet head 1041, and flow through the through hole 11 through the several through slots 211 on the connecting seat 21 to the inside of the pen barrel 101, thereby realizing the ink filling process. After the ink filling is completed, the ink cartridge 104 can be rotated to be taken out of its pen barrel 101 and the pen cap 102 can be installed accordingly to continue. In use, the connecting component 2 repeats the above process during the removal of the ink cartridge 104, and returns to the initial position under the action of the compression spring 24 sleeved on the outside of the connecting rod 23, so that the connecting seat 21 below the mounting groove 1 in the pen body 101 seals the through hole 11. Compared with the traditional gel pen structure that can be refilled with ink, this recyclable ink-refilling gel pen structure has a simpler ink-refilling operation and is less likely to leak ink during the refilling and use process under the action of the integrated pen body 101 and its internal connecting component 2, thereby not easily wasting ink. In addition, this gel pen has a high adaptability to use with the structural setting of the ink cartridge 104, and can be directly installed with the ink cartridge 104 for long-term use according to specific usage requirements. At the same time, it can also reduce the discomfort caused by the ink cartridge 104 during use, meet different usage requirements and improve convenience and flexibility during use.
[0025] The groove structure of the mounting groove 1 is fixed on the inner wall of the pen holder 101 by correspondingly clamping the ring groove 12 provided on the side wall on the rib 1011 provided with the matching ring groove 12. Figure 2 or Figure 5 As shown in the figure, the groove body structure of the installation groove 1 with this structural arrangement can be used to act on the pressure plate 22 on the connecting component 2 through external force, so that the groove body of the installation groove 1 and the connecting component 2 thereon can be installed and disassembled, thereby facilitating the inspection and maintenance of the connecting component 2 and the interior of the pen body 101, and further improving the disassembly and flexibility of use of this recyclable ink-refilling gel pen.
[0026] The connecting seat 21 is provided with a spherical surface 212 corresponding to the size of the through hole 11. Figure 5It can be seen that the provision of the spherical surface 212 on the connecting seat 21 can further improve the sealing performance of the through hole 11, further reducing the probability of ink leakage in the pen barrel 101. At the same time, the spherical surface 212 can also play a certain diversion role for the ink flowing into the pen barrel 101 through the through hole 11 during the ink filling process, further accelerating the fluidity of the ink in the pen barrel 101 during the ink filling process, improving the ink filling efficiency, and also effectively reducing the phenomenon of ink diversion in the pen barrel 101, thereby improving the stability during ink filling and its use.
[0027] The side walls of the through groove 211 on the connecting seat 21 are correspondingly arranged to be inclined. The inclined side walls of the through groove 211 cooperate with the spherical surface 212 on the connecting seat 21 to further improve the fluidity of the ink in the pen body 101. At the same time, the ink flow is more dispersed and uniform, thereby improving the ink filling stability and further improving the ink filling effect and efficiency.
[0028] See also Figure 6-7 The pen tip 103 is rotatably set at a corresponding position at one end of the pen barrel 101 and a core body 1031 is set inside. One end of the core body 1031 is connected to the pen needle 1032 inside the pen tip 103 and the other end is provided with a redundant length placed inside the pen barrel 101. The pen tip 103 is rotatably connected with the threaded structure on the pen barrel 101, which is convenient for the installation, disassembly and replacement of the pen tip 103 to meet different usage requirements. In addition, the adaptive setting of the core body 1031 inside the pen tip 103 can further improve the smoothness of the pen needle 1032 on the pen tip 103 during the writing process by uniformly absorbing the ink in the pen barrel 101, and is less likely to cause ink interruption, while further improving the utilization rate of the ink in the pen barrel 101.
[0029] The inner wall surface of one end of the pen shaft 101 connected to the pen tip 103 is provided with an arc surface 1012 and a closing opening 1013 is provided at the bottom of the arc surface 1012. The closing opening 1013, together with the setting of the arc surface 1012, can play a certain role in guiding the ink in the pen shaft 101, effectively reduce the probability of bubbles generated during the inking process, and improve the stability during the writing process.
[0030] The size of the closing opening 1013 is larger than that of the core body 1031 and extends downward to a certain length. The setting method of the size of the closing opening 1013, combined with the setting of the core body 1031, can further improve the ink absorption effect of the core body 1031. The setting method of the position of the closing opening 1013 can further improve the connection effect between the pen shaft 101 and the pen tip 103, and improve the accumulation effect of ink in the pen tip 103, thereby cooperating with the core body 1031 in the pen tip 103 to further improve the stability and fluency of the writing process.
[0031] The above contents described in this specification are merely examples of the present invention. Those skilled in the art of the present invention may make various modifications, additions, or substitute similar methods to the specific embodiments described, as long as they do not deviate from the contents of this specification or exceed the scope defined by the claims, and shall fall within the scope of protection of the present invention.
