Description

Technical Field

[0001] The utility model relates to the technical field of writing pens, in particular to a touch-controlled writing pen. Background Art

[0002] The smart cloud blackboard adopts multi-point capacitive touch technology, combining traditional handwriting blackboards and multimedia devices, and using ultra-high-definition display technology to easily switch between chalk blackboard writing and multimedia applications. When the screen is on, you can write and draw with a stylus, and when the screen is off, you can write normally like an ordinary blackboard, which brings convenience to teaching work and promotes the diversified development of multimedia teaching.

[0003] Smart cloud blackboards usually come with two types of writing pens, one is a capacitive touch pen and the other is a common writing pen. In traditional technology, the two pens are independent of each other. When using a smart cloud blackboard, you need to switch back and forth between the writing pen and the capacitive touch pen, which is very troublesome.

[0004] In addition, both the writing pen and the capacitive stylus pen are provided with a pen cover, which needs to be removed when in use. After the pen cover is removed, it will be placed on the table and is very easy to be lost. Without the protection of the pen cover, the tip of the writing pen and the capacitive stylus pen is easily damaged when it falls. Utility Model Content

[0005] The utility model provides a touch writing pen with two functions of spacing writing and touch control, which effectively solves the technical problems raised in the above-mentioned background technology.

[0006] The utility model provides the following technical solutions.

[0007] A touch writing pen comprises a holding cylinder, a sliding inner core, a writing pen body and a capacitive touch pen body. The surface in the middle of the holding cylinder is provided with a U-shaped groove guide groove communicated with the interior thereof. The sliding inner core is installed in the holding cylinder, and the outer wall thereof slides in contact with the inner wall of the holding cylinder. A clamping rod is fixed on the outer wall of the sliding inner core. The clamping rod is limitedly slidably arranged in the U-shaped groove guide groove and extends to the outside of the holding cylinder. Guide rods extending along the length direction of the holding cylinder are fixed to both ends of the sliding inner core. The writing pen body is installed on the end of one of the guide rods, and the capacitive touch pen body is installed on the end of the other guide rod. The U-shaped groove guide groove consists of a straight portion and a clamping portion. The two clamping portions are symmetrically distributed at both ends of the straight portion. When the clamping rod is clamped in any clamping portion, a clamping effect is achieved. When the sliding inner core is centered in the holding cylinder, the writing pen body and the capacitive touch pen body are both accommodated in the holding cylinder.

[0008] The touch writing pen provided by the utility model integrates a writing pen body and a capacitive touch pen body in a holding cylinder. By pushing the clamping rod to both sides along the U-shaped groove, the writing pen body or the capacitive touch pen body can be pushed to extend to the outside for use, so that the writing pen body and the capacitive touch pen body share the same holding cylinder. Compared with two traditional independent pens, the touch writing pen has both writing and touching functions in one body, and the function switching process is simple and easy to use. When one pen body is extended for use, the other pen body is stored without interfering with each other. The overall structural layout is reasonable and practical.

[0009] Furthermore, baffle rings are fixed on both sides of the sliding inner core in the holding cylinder, and the guide rods on the same side pass through the baffle rings. Springs are sleeved on the two guide rods, and one end of the spring is fixed to the end face of the sliding inner core, and the other end is fixed to the end face of the baffle ring close to the sliding inner core.

[0010] Furthermore, the distance between the two clamping parts becomes smaller as they are farther away from the straight part, and the clamping parts and the straight part form a whole in the shape of a barb.

[0011] Furthermore, mounting seats are fixed on the ends of the two guide rods away from the sliding inner core body, and internal threaded mounting holes are provided on the two mounting seats. External threaded joints matching the threads of the internal threaded mounting holes are fixed to the tail ends of the writing pen body and the capacitive touch pen body. The writing pen body and the capacitive touch pen body are matched with the threads of the internal threaded mounting holes through the external threaded joints, and are detachably screwed onto the two mounting seats respectively.

[0012] Furthermore, the portion of the clamping rod extending to the outside of the holding cylinder is a flat portion, and second anti-slip patterns are provided on the surfaces on both sides of the flat portion.

[0013] Furthermore, the outer wall of the holding cylinder is provided with holding parts near both ends thereof, and the outer walls of the holding parts are provided with first anti-slip patterns.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows.

[0015] 1. The utility model integrates the writing pen body and the capacitive touch pen body into a holding cylinder. By pushing the clamping rod to both sides along the U-shaped groove, the writing pen body or the capacitive touch pen body can be pushed to extend to the outside for use, so that the writing pen body and the capacitive touch pen body share the same holding cylinder. Compared with the two traditional independent pens, the touch writing pen has both writing and touch functions in one, and the function switching process is simple and easy to use. When one pen body is extended for use, the other pen body is stored without interfering with each other. The overall structural layout is reasonable and practical.

[0016] 2. When the utility model pushes the clamping rod back from any clamping part to the straight part, the elastic force of the two springs can drive the sliding inner core to automatically slide to the middle of the holding cylinder, so as to realize the automatic centering reset of the sliding inner core, and then drive the writing pen body and the capacitive touch pen body to retract and be stored in the holding cylinder at the same time. The holding cylinder can replace the traditional pen cover to provide protection for the writing pen body and the capacitive touch pen body, and prevent the pen head of the writing pen body and the pen tip of the capacitive touch pen body from being damaged due to falling and contacting the ground, thereby avoiding the problem of being unable to provide protection for the writing pen body and the capacitive touch pen body due to the loss of the pen cover.

[0017] 3. The utility model installs external threaded connectors at the tail ends of the writing pen body and the capacitive touch pen body, and screws the writing pen body or the capacitive touch pen body onto the mounting seat by using the threads of the external threaded connector and the internal threaded mounting hole, so that the writing pen body or the capacitive touch pen body has a detachable effect. When the writing pen body or the capacitive touch pen body is extended to the outside of the holding cylinder, the writing pen body or the capacitive touch pen body can be unscrewed from the mounting seat, which is convenient for disassembly, inspection, maintenance or replacement of the writing pen body or the capacitive touch pen body when it is damaged.

[0027] Please refer to Figure 1-Figure 4 The utility model provides a touch writing pen, comprising a gripping cylinder 1, a sliding inner core 3, a writing pen body 5 and a capacitive touch pen body 6. The surface of the gripping cylinder 1 in the middle is provided with a U-shaped groove guide groove 2 communicated with the inside thereof. The sliding inner core 3 is installed in the gripping cylinder 1, and the outer wall is slidably fitted with the inner wall of the gripping cylinder 1. A clamping rod 4 is fixed on the outer wall of the sliding inner core 3. The clamping rod 4 is limitedly slidably arranged in the U-shaped groove guide groove 2 and extends to the outside of the gripping cylinder 1. Guide rods 7 extending along the length direction of the gripping cylinder 1 are fixed on both ends of the sliding inner core 3. The writing pen body 5 is installed On the end of one of the guide rods 7, the capacitive touch pen body 6 is installed on the end of the other guide rod 7. The U-shaped groove guide groove 2 is composed of a straight portion 21 and a clamping portion 22. The two clamping portions 22 are symmetrically distributed at both ends of the straight portion 21. When the clamping rod 4 is clamped into any clamping portion 22, the clamping effect is achieved. When the sliding inner core 3 is centered in the holding cylinder 1, the writing pen body 5 and the capacitive touch pen body 6 are both received in the holding cylinder 1. It is worth noting that the writing pen body 5 and the capacitive touch pen body 6 in the present application both adopt the existing technology, and the specific shape structure and working principle are not repeated here.

[0028] When the writing pen body 5 needs to be used for normal writing, the clamping rod 4 is pushed along the straight portion 21 toward the side away from the capacitive touch pen body 6 until the clamping rod 4 is pushed into the clamping portion 22 away from the side of the capacitive touch pen body 6. In this process, the clamping rod 4 drives the sliding inner core 3 to move toward the side away from the capacitive touch pen body 6, thereby driving the writing pen body 5 to extend from the port of the holding cylinder 1 to the outside. At the same time, the clamping rod 4 is clamped into the clamping portion 22 away from the side of the capacitive touch pen body 6, which has a clamping effect, thereby ensuring the stability of the writing pen body 5 during normal writing and preventing the writing pen body 5 from retracting to the In the holding cylinder 1, when the capacitive touch pen body 6 needs to be used for screen touch, similarly, the clamping rod 4 is pushed along the straight portion 21 to the side away from the writing pen body 5 until the clamping rod 4 is pushed to the clamping portion 22 on the side away from the writing pen body 5, which can drive the capacitive touch pen body 6 to extend from the end of the holding cylinder 1. Similarly, the clamping rod 4 is clamped into the clamping portion 22 on the side away from the writing pen body 5, which has a clamping effect, thereby ensuring the stability of the capacitive touch pen body 6 during touch, and preventing the capacitive touch pen body 6 from retracting into the holding cylinder 1, so that the touch writing pen has both writing and touch functions.

[0029] The touch writing pen integrates the writing pen body 5 and the capacitive touch pen body 6 in the holding cylinder 1. By pushing the clamping rod 4 to both sides along the U-shaped groove guide groove 2, the writing pen body 5 or the capacitive touch pen body 6 can be pushed out to the outside for use, so that the writing pen body 5 and the capacitive touch pen body 6 share the same holding cylinder 1. Compared with the two traditional independent pens, the touch writing pen has both writing and touching functions in one body. The function switching process is simple and easy to use. When one pen body is extended for use, the other pen body is stored without interfering with each other. The overall structural layout is reasonable and practical.

[0030] like Figure 2 and Figure 3 As shown, retaining rings 8 are fixed on both sides of the sliding inner core 3 in the holding cylinder 1, and the guide rod 7 on the same side passes through the retaining ring 8. Springs 71 are sleeved on the two guide rods 7, and one end of the spring 71 is fixed to the end face of the sliding inner core 3, and the other end is fixed to the end face of the retaining ring 8 close to the sliding inner core 3.

[0031] The distance between the two clamping portions 22 becomes smaller as it is farther away from the straight portion 21 , and the clamping portions 22 and the straight portion 21 are integrally formed in a barb shape.

[0032] When the writing pen body 5 is pushed out of the holding cylinder 1, the spring 71 close to the writing pen body 5 is elastically compressed, and the spring 71 close to the capacitive touch pen body 6 is elastically stretched, and both springs 71 store force elastically. When the clamping rod 4 is clamped into the clamping portion 22 close to one side of the writing pen body 5, the clamping rod 4 is clamped and limited by the hook-shaped structure formed by the clamping portion 22 and the straight portion 21 to ensure the stability of the writing pen body 5 when in use. Similarly, when the capacitive touch pen body 6 is pushed out of the holding cylinder 1, the spring 71 close to the capacitive touch pen body 6 is elastically compressed, and the spring 71 close to the writing pen body 5 is elastically stretched, and both springs 71 store force elastically. When the clamping rod 4 is clamped into the clamping portion 22 close to one side of the capacitive touch pen body 6, the clamping rod 4 is clamped and limited by the hook-shaped structure formed by the clamping portion 22 and the straight portion 21 to ensure the stability of the capacitive touch pen body 6 when in use.

[0033] In addition, when the clamping rod 4 is pushed back from any clamping portion 22 to the straight portion 21, the elastic force of the two springs 71 can drive the sliding inner core 3 to automatically slide to the middle of the holding cylinder 1, thereby realizing automatic centering and resetting of the sliding inner core 3, and then can drive the writing pen body 5 and the capacitive touch pen body 6 to retract and be stored in the holding cylinder 1 at the same time. The holding cylinder 1 can replace the traditional pen cover to provide protection for the writing pen body 5 and the capacitive touch pen body 6, and prevent the pen head of the writing pen body 5 and the pen tip of the capacitive touch pen body 6 from being damaged due to falling and contacting the ground, thereby avoiding the problem of being unable to provide protection for the writing pen body 5 and the capacitive touch pen body 6 due to the loss of the pen cover.

[0034] like Figure 2 As shown, mounting seats 72 are fixed on the ends of the two guide rods 7 away from the sliding inner core 3, and internal threaded mounting holes 721 are provided on the two mounting seats 72. External threaded connectors 73 that match the threads of the internal threaded mounting holes 721 are fixed to the tails of the writing pen body 5 and the capacitive touch pen body 6. The writing pen body 5 and the capacitive touch pen body 6 are matched with the threads of the internal threaded mounting holes 721 through the external threaded connectors 73, and are respectively detachably screwed on the two mounting seats 72. The writing pen body 5 and the capacitive touch pen body 6 can be equipped with multiple ones respectively.

[0035] By installing an external threaded connector 73 at the tail end of the writing pen body 5 and the capacitive touch pen body 6, and utilizing the threaded cooperation between the external threaded connector 73 and the internal threaded mounting hole 721, the writing pen body 5 or the capacitive touch pen body 6 is screwed onto the mounting seat 72, so that the writing pen body 5 or the capacitive touch pen body 6 has a detachable effect. When the writing pen body 5 or the capacitive touch pen body 6 is extended to the outside of the holding cylinder 1, the writing pen body 5 or the capacitive touch pen body 6 can be unscrewed from the mounting seat 72, which is convenient for disassembly, inspection, maintenance or replacement of the writing pen body 5 or the capacitive touch pen body 6 when it is damaged.

[0036] like Figure 1 , Figure 3 and Figure 4 As shown, the portion of the card rod 4 extending to the outside of the holding cylinder 1 is a flat portion 41. When the flat portion 41 is pinched to push the card rod 4 to move, the flat surface of the flat portion 41 can increase the contact area with the fingers, thereby facilitating the force to push the card rod 4 to move. In addition, second anti-slip grooves 411 are provided on the surfaces of both sides of the flat portion 41 to increase the friction between the flat portion 41 and the fingers and avoid slipping during the pushing process.

[0037] The outer wall of the holding cylinder 1 has holding parts 11 near both ends thereof, and the outer walls of the holding parts 11 are provided with first anti-slip grooves 111. By holding the two holding parts 11 on the holding cylinder 1 respectively, writing or touch operations are convenient, and the first anti-slip grooves 111 on the holding parts 11 can increase the friction between the hands, ensuring that the hand-held use is more stable and will not slip out of the hand.

[0038] In addition, the two gripping parts 11 have different colors, so as to easily distinguish the writing pen body 5 from the capacitive touch pen body 6 , which is highly practical.

[0039] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited to them. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model; in the absence of conflicts, the embodiments of the utility model and the features in the embodiments can be combined with each other. Therefore, the protection scope of the utility model shall be based on the protection scope of the claims.
