Detailed Implementation
[0026] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.
[0027] See Figures 1-5 This embodiment discloses an anti-static pen, including a pen barrel 1, an anti-static component 2 for eliminating static electricity, and a pen refill component 3 for writing. The pen barrel 1 includes an upper body 11 and a lower body 12, both of which are made of metal. The inner ends of the upper body 11 and the lower body 12 are connected by a connecting tube 13. The two ends of the connecting tube 13 are respectively inserted into and detachably connected to the upper body 11 and the lower body 12, and the central axes of the three are on the same straight line. The connecting tube 13 is made of transparent plastic. The anti-static component 2 is located in the cavity of the connecting tube 13. The input end and the output end of the anti-static component 2 are respectively connected to the lower body 12 and the upper body 11. The pen refill component 3 is inserted along the axial direction of the pen barrel 1 and detachably installed on the upper body 11.
[0028] The static elimination component 2 includes a neon bulb 21 and a resistor 22. Both the neon bulb 21 and the resistor 22 are located in the cavity of the connecting tube 13. One end of the resistor 22 is clamped between the lower rod 12 and the connecting tube 13, and the other end of the resistor 22 is connected to the pin of one end of the neon bulb 21. The other end of the neon bulb 21 is clamped between the upper rod 11 and the connecting tube 13.
[0029] When the pen is used to eliminate static electricity, the user holds the upper rod 11 and moves it so that the lower rod 12 comes into contact with a statically charged object. When the lower rod 11 comes into contact with the statically charged object, the static charge on the object, which is in a static state, will sequentially transfer to the lower rod 12, resistor 22, neon bulb 21, and then to the upper rod 11. During this process, the current formed by the directional transfer of static charge will cause the neon bulb 21 to light up, thus releasing and dissipating the static electricity, thereby achieving the purpose of eliminating static electricity. At the same time, the user can also visually judge the extent of static electricity release and elimination on the object by observing whether the neon bulb 21 is on or off.
[0030] In this embodiment, the upper rod 11, the connecting pipe 13, and the lower rod 12 are all connected by an interference fit.
[0031] See Figure 1 The upper rod 11 has a pen clip 4 on the side of its outer end, which makes it convenient to carry the pen with the pen by clipping it.
[0032] See Figure 3 , Figure 4 The pen refill assembly 3 includes a pen body 31 and a pen refill 32. The pen body 31 is a tubular structure with an open bottom and a closed top. The pen refill 32 is slidably disposed in the cavity of the pen body 31. The upper and lower parts of the cavity of the pen body 31 are both cylindrical. The diameter of the pen refill 32 is smaller than the diameter of the upper part of the cavity of the pen body 31, and the diameter of the upper part of the cavity of the pen body 31 is smaller than the diameter of the lower part of the cavity of the pen body 31. A first through hole 33 communicating with the cavity is opened on the end face of the top of the pen body 31. A pointed sleeve 34 for preventing the pen refill 32 from detaching from the bottom of the pen body 31 is sleeved and detachably installed on the bottom of the pen body 31. The pointed sleeve 34 is detachably connected to the lower rod 12.
[0033] When the pen is used for writing, the tip of the pen is turned downwards, causing the lead 32 inside the pen body 31 to extend out under the influence of gravity. At this time, the lead 32 is completely located in the lower part of the cavity of the pen body 31. Because the pen is tilted when writing, and the lead 32 inside the pen body 31 has corresponding space for movement, the lead 32 can be prevented from retracting into the pen body 31 by pressing against the top surface of the lower part of the cavity of the pen body 31, which is formed by the difference in diameter between the upper and lower parts of the cavity, thus ensuring normal writing use.
[0034] When writing, the pen tip is turned upwards, so that the pen lead 32 moves from the lower part of the pen body 31 cavity to the upper part of the pen body 31 cavity under the action of gravity. The pen lead 32 retracts into the pen body 31, which serves to protect the pen lead 32.
[0035] In this embodiment, the pen body 31, the tip sleeve 34, and the lower rod body 12 are all connected by a threaded structure.
[0036] See Figure 3 A spring 5 is fitted onto the pen refill 32, and the diameter of the spring 5 is larger than the diameter of the upper part of the cavity of the pen body 31. When the pen tip is turned from downward to upward, the pen refill 32 retracts into the pen body 31, while the spring 5 slides relative to the pen refill 32 under the influence of gravity. Because the spring 5 moves and squeezes between the pen refill 32 and the side of the pen body 31 during its movement, it effectively pushes the pen refill 32, guiding it from the lower part of the cavity of the pen body 31 into the upper part of the cavity. This ensures the smoothness and effectiveness of the pen refill 32 retracting into the pen body 31 and reduces the risk of the pen refill 32 being exposed and damaged when the pen is not in use.
[0037] See Figure 4 A metal post 6 is inserted and fixed at the tail end of the pen refill 32 to ensure the effectiveness of the pen refill 32 sliding relative to the pen body 31 under the action of gravity. A second through hole 61 is opened through the metal post 6 along its axial direction to reduce the impact of the installation of the metal post 6 on the ink output of the pen refill 32.
[0038] See Figure 5 The lower rod 12 has an installation head 7 on its outer end. The inner end of the installation head 7 is inserted into and detachably connected to the end face of the outer end of the lower rod 12, and a rubber head 8 is sleeved on its outer end, so that the pen can be used as a stylus, which improves the functionality of the pen. A limiting ring 9 is sleeved on the outer end of the installation head and detachably installed to prevent the rubber head 8 from detaching from the outer end of the installation head 7. The rubber head 8 passes through the limiting ring 9, which improves the convenience and firmness of installing the rubber head 8 on the lower rod 12.
[0039] In this embodiment, the mounting head 7 and the lower rod body 12 are connected by an interference fit, and the limiting ring 9 and the mounting head 7 are connected by a threaded structure.
[0040] The above description in this specification is merely illustrative of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
