DETAILED DESCRIPTION
[0025] 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.
[0026] See also Figures 1-4 The present embodiment provides a telescopic luminous pen, comprising a pen body 1, a telescopic rod 2 being provided at the top of the pen body 1, the telescopic rod 2 being made of a light-transmitting material and a decorative part 3 being detachably mounted on the top thereof, a light-emitting component 4 for emitting light being provided in the cavity of the pen body 1, the light-emitting component 4 being detachably mounted in the cavity of the pen body 1, a driving block 5 being slidably connected to the side of the pen body 1, the light-emitting component 4 being turned on and off by a pressure switch 6, and a trigger end 61 of the pressure switch 6 being located on the moving track of the protrusion 51 on the driving block 5.
[0027] During use, by pushing the driving block 5 to slide, the driving block 5 can contact and squeeze the trigger end 61 of the pressure switch 6 during the sliding process to close the pressure switch 6, so that the light-emitting component 4 changes from the closed state to the open state. At the same time, when the driving block 5 is pushed to reset, the driving block 5 releases the squeezing effect on the pressure switch 6, so that the pressure switch 6 is reset, and the light-emitting component 4 changes from the open state to the closed state.
[0028] To enhance the pen's luminous effect, the decorative element 3 can be designed in a cartoon-like shape that complements the telescopic rod 2. In this embodiment, the decorative element 3 is shaped like a flying saucer. This, combined with the telescopic effect of the telescopic rod 2 and its tower-like shape (i.e., a smaller top and larger bottom), creates a visual effect of the saucer-shaped decorative element 3 rising and falling while emitting a light beam, enhancing the pen's fun. Furthermore, the decorative element 3 can also be made of a translucent material.
[0029] See also Figure 1 The outer surface of the driving block 5 is provided with a friction texture 52, which ensures the effectiveness of driving the driving block 5 to move, thereby improving the smoothness of switching the control pen between turning on and off the lighting function.
[0030] See also Figure 1 、 Figure 2 The pen body 1 includes a first rod body 11 and a second rod body 12. The first rod body 11 is a hollow structure with an open top and a closed bottom. The light-emitting component 4 is installed in the cavity of the first rod body 11. A through hole 13 is opened on the side of the first rod body 11. The trigger end 61 of the pressure switch 6 is located in the through hole 13. The driving block 5 is slidably connected in the through hole 13. The bottom end of the telescopic rod 2 is detachably connected to the top of the first rod body 11. The second rod body 12 is a hollow structure with openings at both ends. The bottom end of the first rod body 11 is inserted and fixed on the top of the second rod body 12. A pen core 14 is provided in the cavity of the second rod body 12. The pen core 14 is clamped between the first rod body 11 and the second rod body 12. The top of the pen core 14 is against the bottom end of the first rod body 11 and its bottom end passes through the second rod body 12 and is exposed outside the second rod body 12. Through the assembled structure of the pen body 1, the components of the pen body 1 can be manufactured separately, which reduces the manufacturing difficulty of the pen body 1 and reduces manufacturing losses. At the same time, it facilitates the assembly of the various components in the pen body 1 and ensures manufacturing efficiency.
[0031] See also Figure 2 The bottom end of the second rod body 12 is sleeved and fixed with a tip sleeve 15, and the bottom end of the pen core 14 is passed through the tip sleeve 15, ensuring the user's observation field of view of the writing area when writing, thereby ensuring the writing effect.
[0032] In this embodiment, the tip sleeve 15 and the second rod body 12 can be connected by threaded engagement, which facilitates the replacement of the pen core 14 in the second rod body 12 .
[0033] See also Figure 2 、 Figure 3 A pen cap 16 is mounted and fixed on the bottom end of the second rod body 12, which protects the pen core 14, thereby ensuring the service life of the pen for writing. The bottom surface of the pen cap 16 is an arc surface 17, which reduces the risk of puncture caused by the pen cap 16.
[0034] In this embodiment, the pen cap 16 and the first rod body can be connected by a snap-fit structure, which ensures the convenience of installing and removing the pen cap 16.
[0035] See also Figure 3 The telescopic rod 2 includes a third rod 21, a fourth rod 22, and a fifth rod 23, which are sequentially inserted. The diameters of the third rod 21, the fourth rod 22, and the fifth rod 23 gradually decrease along the extension direction of the telescopic rod 2. The fourth rod 22 and the fifth rod 23 are both tubular structures with open ends. The decorative member 3 is detachably mounted on the top of the third rod 21. The maximum diameter of the third rod 21 is smaller than the minimum diameter of the fourth rod 22, and the maximum diameter of the fourth rod 22 is smaller than the minimum diameter of the fifth rod 23. The bottom end of the fifth rod 23 is detachably mounted on the top of the pen body 1. The sequential arrangement of the diameters of the third rod 21, the fourth rod 22, and the fifth rod 23 ensures smooth retraction and extension of the telescopic rod 2 on the pen body 1, thereby ensuring that the pen can switch between a retracted state and an extended state.
[0036] See also Figure 4 The light-emitting component 4 includes an LED lamp bead, a power supply consisting of at least one button battery, and a mounting base 43 for accommodating the power supply. The LED lamp bead and the power supply are electrically connected through a pressure switch 6 to form a closed circuit. The mounting base 43 is inserted and fixed in the cavity of the first rod body 11. The LED lamp bead is fixed on the top of the mounting base 43 and its top end is located in the opening at the top end of the first rod body 11. The pressure switch 6 is fixed on the mounting base 43.
[0037] When in use, the trigger end 61 of the pressure switch 6 is squeezed by the driving block 5, so that the trigger end 61 of the pressure switch 6 can contact the other pin of the LED lamp bead, so that the closed circuit on the light-emitting component 4 is connected, so that the LED lamp bead lights up, and when the driving block 5 releases the squeezing of the trigger end 61 of the pressure switch 6, the pressure switch 6 gradually separates from the other pin of the LED lamp bead, so that the closed circuit on the light-emitting component 4 is disconnected, and the LED lamp bead is extinguished.
[0038] In this embodiment, the power source is three button batteries stacked in the same direction. One of the two pins of the LED lamp bead is clamped between the positive end of the button battery located at the top and the mounting base 43. The power connection end 62 of the pressure switch 6 is clamped between the negative end of the button battery located at the bottom and the mounting base 43. The other pin of the LED lamp bead is located on the moving track of the trigger end 61 of the pressure switch 6.
[0039] In this embodiment, in addition to the above-mentioned fixed arrangement of the refill 14 on the pen body 1, a sliding arrangement can also be adopted, that is, the refill 14 is slidably arranged in the cavity of the second rod body 12, and a spring is provided between the bottom end of the refill 14 and the second rod body 12 for applying a force to the refill 14 to extend into the second rod body 12, and the two ends of the spring are respectively against the bottom end of the refill 14 and the second rod body 12, and a spring is provided between the top end of the refill 14 and the first rod body 11 for driving the refill 14 to extend and retract from the pen body 1. The telescopic locking mechanism, the inner end of the driving block 5 is integrally connected to the mounting seat 43, the mounting seat 43 is slidably arranged in the cavity of the first rod body 11, the pressure rod of the telescopic locking mechanism is integrally connected to the bottom end of the mounting seat 43, the guide rail of the telescopic locking mechanism is integrally connected to the second rod body 12, the locking member is slidably arranged in the cavity of the second rod body 12 and is clamped at the top end of the pen core 14 and the pressure rod member, the first rod body 11 is provided with a limit block, the limit block is located on the moving track of the trigger end 61 of the pressure switch 6, as shown in FIG. Figure 5 As shown in .
[0040] When in use, by pushing the driving member, the driving member drives the light-emitting component 4 to slide together, thereby pressing the pressure rod, so that the pen core 14 is extended from the pen body 1 under the action of the telescopic locking mechanism, and in this process, the trigger end 61 of the pressure switch 6 contacts the limit block and is closed under the pressure of the limit block, so that the light-emitting component 4 changes from the closed state to the open state, thereby achieving the effect of the pen being in the writing use state and the lighting use state at the same time, improving the convenience of operating the pen in a dark environment.
[0041] In this embodiment, the telescopic locking mechanism adopts the conventional setting structure of the telescopic locking mechanism in the press pen, so the structural setting relationship between the pressure rod, the guide rail and the locking member in the telescopic locking mechanism is no longer described in detail.
