Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of enameled wires, in particular to a pressure-sensitive pen with a quick-change structure. Background Art
[0002] A pressure-sensitive pen is a digital tool specifically used for drawing. It is usually used with a digital tablet to achieve more precise image creation and modification. This electronic pen has a pressure-sensitive function and can simulate writing or painting effects under different pressures according to the pressure applied by the user, such as imitating a brush to draw a layered ink painting.
[0003] When using a pressure-sensitive pen, the pressure is mainly transmitted through the pen core. Specifically, it simulates the writing or painting effects under different pressures according to the pressure applied by the user. For example, when the user presses hard on the pressure-sensitive pen, the pen core will be stressed and deformed. This deformation will be captured by the pressure-sensitive pen and converted into changes in line thickness, so that it can imitate a brush to draw a layered ink painting.
[0004] However, the refill of the pressure-sensitive pen is a consumable and will cause wear during long-term use. When the refill of the pressure-sensitive pen is worn to a certain extent, it may affect the drawing effect, so it needs to be replaced to maintain the accuracy of the drawing. However, when replacing the refill, since the part of the refill outside the pressure-sensitive pen is shorter, it is necessary to clamp the tip of the refill with a special clamp similar to tweezers, pull it out of the pressure-sensitive pen, and replace the refill. This replacement method is limited by the clamp. In the absence of a special clamp, it is difficult to replace the refill of the pressure-sensitive pen. Therefore, a pressure-sensitive pen with a quick-replacement structure is proposed, and the refill can be replaced without using a special clamp. Utility Model Content
[0005] The purpose of the utility model is to provide a pressure-sensitive pen with a quick-change structure to solve the problems raised in the above-mentioned background technology.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a pressure-sensitive pen with a quick-change structure, used for drawing on a digital tablet, comprising a pen holder, a grip rod installed at the lower end of the pen holder, and also comprising: a pen core is inserted into the lower side of the grip rod, an installation cavity is opened inside the grip rod, an adjustment frame is slidably connected to the inside of the installation cavity, and the adjustment frame is located on the outside of the push rod.
[0007] On the basis of the above technical solution, the present invention can also be improved as follows.
[0008] Preferably, a fixing ring is fixedly connected to the bottom of the gripping rod, and the fixing ring is located outside the pen core.
[0009] Preferably, a rubber anti-skid sleeve is sleeved on the outer side of the pen core, and the rubber anti-skid sleeve is located below the adjustment frame.
[0010] Preferably, a plug hole is provided inside the rubber anti-slip sleeve, and an expansion port is provided at the lower side of the plug hole.
[0011] Preferably, a pressing block is fixedly connected to the outer end of the adjustment frame, and one end of the pressing block extends to the outer side of the grip.
[0012] Preferably, a return spring is fixedly connected to one end of the adjustment frame away from the pressing block, and the return spring is fixedly connected to the inside of the installation cavity.
[0013] Preferably, the outer end of the push rod is fixedly connected to two docking blocks, which are respectively located at the front and rear sides of the push rod.
[0014] Preferably, two groups of limiting grooves are provided on the inner side of the adjustment frame, and the docking block is slidably connected to the limiting grooves.
[0015] Beneficial Effects
[0016] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:
[0017] The utility model can adjust the push rod by arranging an adjustment frame, and the adjustment frame can slide by pressing the pressing block. Since the adjustment frame is connected with the docking block at the outer end of the push rod through the inner limiting groove, the push rod can be driven to rise and fall by the sliding of the adjustment frame. When the push rod is descending, it resists the pen core and pushes more of the pen core out of the grip, so that the user can directly pull the pen core out of the grip for replacement.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] A pressure-sensitive pen with a quick-change structure comprises a pen holder 1, a grip 2 is arranged at the lower end of the pen holder 1, the grip 2 is fixed to the pen holder 1, a pen core 3 is inserted at the lower side of the grip 2, and when the pressure-sensitive pen is in use, the pen core 3 contacts a digital tablet.
[0026] In this embodiment, Figure 1 , Figure 2 and Figure 3 The handle 2 is provided with a mounting cavity 21 inside, and the mounting cavity 21 is slidably connected with an adjustment frame 50 inside, and the adjustment frame 50 is located outside the push rod 4. The push rod 4 can be driven to rise and fall through the sliding translation of the adjustment frame 50.
[0027] Specifically, a pressing block 51 is fixed to the outer end of the adjustment frame 50, and one end of the pressing block 51 extends to the outer side of the grip 2, so that the user can press the pressing block 51, and the adjusting frame 50 is driven to slide in translation by the pressing block 51, and docking blocks 41 are respectively provided on the front and rear sides of the push rod 4, and the number of docking blocks 41 is two and fixed to the outer end of the push rod 4, and two groups of limiting grooves 501 are provided on the inner side of the adjustment frame 50, and the docking blocks 41 are slidably connected to the inner side of the limiting grooves 501, so that the limiting grooves 501 limits the movement of the docking block 41. When the adjustment frame 50 slides in a translational manner, the docking block 41 can be used to slide in a limited manner in the limiting groove 501 to drive the push rod 4 to move up and down. When the push rod 4 descends, it can resist the pen core 3. During the descending process of the push rod 4, the pen core 3 is gradually pushed out of the grip 2 by the push rod 4, thereby raising the portion of the pen core 3 located outside the grip 2, making it easier for the user to pinch the portion of the pen core 3 located outside the grip 2 and pull it out of the grip 2 to quickly replace the pen core 3.
[0028] Furthermore, a return spring 52 is fixed to one end of the adjustment frame 50 away from the pressing block 51, and the return spring 52 is fixed inside the mounting cavity 21. The push rod 4 is reset by the elastic force of the return spring 52. When the user does not press the pressing block 51, the return spring 52 pushes the adjustment frame 50 to cause it to translate, and the push rod 4 is driven to rise as a whole through the limited sliding of the docking block 41 in the limit groove 501, and no longer interferes with the pen core 3.
[0029] In a further embodiment, Figure 1 , Figure 4 and Figure 5 The outer side of the pen core 3 is sleeved with a rubber anti-skid sleeve 6 located below the adjustment frame 50, the rubber anti-skid sleeve 6 is fixed inside the grip 2, and an insertion hole 61 is provided inside the rubber anti-skid sleeve 6, so that the pen core 3 can pass through the insertion hole 61, and the pen core 3 is squeezed by the elastic force of the rubber anti-skid sleeve 6 to prevent the pen core 3 from slipping out of the grip 2 due to its own weight, and an expansion port is provided on the lower side of the insertion hole 61, so that the pen core 3 can be better inserted into the insertion hole 61, and the pen core 3 and the grip 2 can be quickly assembled.
[0030] In another embodiment, if Figure 1 and Figure 4 A fixing ring 22 is fixed at the bottom of the grip 2, and the fixing ring 22 is located on the outside of the pen core 3, so that when the pen core 3 contacts the digital tablet for drawing, the fixing ring 22 can limit and support the exposed part of the pen core 3, thereby improving the stability during use.
