Description

Technical Field

[0001] This utility model relates to the field of reading pen technology, specifically a reading pen that can be placed stably. Background Technology

[0002] The reading pen is a new generation of intelligent reading and learning tool developed using the latest international optical image recognition technology and advanced digital voice technology.

[0003] An existing patent (publication number: CN220773779U) discloses a stable reading pen. It includes a pen barrel and a pen tip. The pen tip is mounted at the end of the pen barrel, and a protective sleeve is slidably fitted onto the surface of the pen barrel. Multiple equally spaced anti-slip protrusions are fixedly installed on each opposite side of the protective sleeve, and a first limiting mechanism for limiting the protective sleeve is provided on each opposite side of the pen barrel. A circular inner cavity is opened at the top of the pen barrel, and two symmetrically arranged top covers are fixedly installed on the top of the pen barrel. Two symmetrically arranged sliding plates slide on opposite sides of the two top covers, and a second limiting mechanism for limiting the sliding plates is provided on the side of each top cover. This invention increases the contact area between the pen tip and the placement surface when the reading pen is placed vertically, making the reading pen more stable and less prone to tipping over, thereby improving the stability of the device.

[0004] When the aforementioned reading pen is placed vertically, the counterweight moves under the influence of gravity. This movement of the counterweight causes two movable rods to move, which in turn causes two sliding plates to move, thus expanding the placement range of the reading pen and improving its stability. However, while the reading pen expands its placement range through the two sliding plates, it is prone to tipping over when an external force is applied from one side of the two sliding plates, indicating low support stability. Furthermore, when not in use, users often need to turn off the monitor power first. If users forget to turn off the power, the reading pen's battery power is easily wasted and damaged. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a stable reading pen with advantages such as energy saving, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a stable reading pen, comprising a pen shell, a placement cylinder fixedly connected to the top of the pen shell, four circumferentially arranged sliding grooves on the top of the placement cylinder, an expansion plate slidably connected inside each sliding groove, a counterweight ball slidably connected up and down inside the placement cylinder, an insertion rod fixedly connected to the inner bottom wall of the top of the placement cylinder, a movable cylinder slidably sleeved on the outer surface of the insertion rod, multiple connecting rods hinged to the outer surface of the movable cylinder, the other end of each connecting rod being hinged to the expansion plate adjacent to it, and a contact plate fixedly connected to the bottom end of the movable cylinder.

[0007] Furthermore, a control panel is provided on the outer surface of the pen shell, and micro switches are provided on the inner bottom wall of the movable cylinder and the bottom end of the insertion rod. Both micro switches are electrically connected to the control panel.

[0008] With the above scheme, when the pen shell is placed upside down, the counterweight ball pushes the contact plate and the moving sleeve to move with gravity, and the two microswitches can get close to each other, so that the two microswitches make contact and conduction, triggering the control panel to enter sleep mode.

[0009] Furthermore, the outer surface of the pen casing is provided with an arc-shaped groove.

[0010] The above design makes it easier for users to hold the reading pen.

[0011] Furthermore, two symmetrically arranged anti-roll buttons are fixedly connected to the middle of the pen shell.

[0012] The above solution can effectively prevent the pen casing from rolling on the table when the reading pen is placed flat.

[0013] Furthermore, a compression spring is provided between the top of the movable cylinder and the inner top wall of the placement cylinder, and the compression spring is sleeved with the insertion rod.

[0014] With the above solution, the expansion plate automatically resets when the pen tip is facing down during use, and the two microswitches move away from each other, automatically waking up the control panel for quick and easy use.

[0015] Furthermore, the upper surface of each of the expansion plates is at the same level as the top of the placement cylinder.

[0016] The above scheme and settings can ensure the flatness of the expansion plate and the top of the placement cylinder, thereby guaranteeing placement stability.

[0017] Furthermore, the counterweight ball is made of a metallic material.

[0018] The above scheme ensures that the mass of the counterweight ball is sufficient to provide enough gravity to trigger the expansion of the expansion plate.

[0019] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0020] This stable reading pen achieves stable support through four-way movable expansion plates. Compared with the existing two-way sliding plate design, the four circumferentially arranged expansion plates form a symmetrical support surface when inverted, effectively resisting lateral forces from any direction and solving the defect of easy tipping of traditional two-point support. The synergistic effect of the counterweight ball and micro switch automatically triggers the sleep mode when inverted, solving the problem of power loss caused by users forgetting to turn off the power. The spring reset ensures that the device is immediately awakened when the pen returns to the normal use posture. It is more reliable than pure electronic sensors and avoids the risk of accidental triggering. Attached Figure Description

[0027] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] Please see Figure 1 , Figure 3 and Figure 4This embodiment of a stable reading pen includes a pen shell 1. The outer surface of the pen shell 1 has an arc-shaped groove 12 for easy gripping. A placement cylinder 2 is fixedly connected to the top of the pen shell 1. The top of the placement cylinder 2 has four circumferentially arranged sliding grooves 3. An expanding plate 4 is slidably connected inside each sliding groove 3. A counterweight ball 5 is slidably connected up and down inside the placement cylinder 2. An insertion rod 6 is fixedly connected to the inner bottom wall of the top of the placement cylinder 2. A movable cylinder 7 is slidably sleeved on the outer surface of the insertion rod 6. Multiple connecting rods 8 are hinged to the outer surface of the movable cylinder 7. The other end of each connecting rod 8 is hinged to the expanding plate 4 adjacent to it. The bottom of the movable cylinder 7 is fixedly connected to a contact plate 9. With the setting of the expansion plate 4, when the reading pen is inverted, the expansion plate 4 can slide outward to increase the contact area with the external table, thereby ensuring placement stability. Due to the circumferential arrangement of the four expansion plates 4, its support stability can be further improved. The upper surface of each expansion plate 4 is at the same level as the top of the placement cylinder 2. Through the above settings, the flatness of the expansion plate 4 and the top of the placement cylinder 2 can be achieved, thereby ensuring placement stability. The counterweight ball 5 is made of metal to ensure the mass of the counterweight ball 5, which can provide sufficient gravity to trigger the expansion of the expansion plate 4.

[0029] Please see Figure 1 , Figure 2 and Figure 3 Two symmetrically arranged anti-roll keys 13 are fixedly connected to the middle of the pen shell 1. The anti-roll keys 13 can effectively prevent the pen shell 1 from rolling on the table when the pen is placed flat. The outer surface of the pen shell 1 is provided with a control panel 10. The inner bottom wall of the moving tube 7 and the bottom end of the insertion rod 6 are both provided with micro switches 11. Both micro switches 11 are electrically connected to the control panel 10. When the pen shell 1 is placed upside down, the counterweight ball 5 pushes the contact plate 9 and the moving sleeve to move with gravity. The two micro switches 11 can approach each other, so that the two micro switches 11 make contact and conduction, triggering the control panel 10 to enter sleep mode.

[0030] Please see Figure 1 , Figure 2 and Figure 3 A compression spring 14 is provided between the top of the moving cylinder 7 and the inner top wall of the placing cylinder 2. The compression spring 14 is sleeved with the insertion rod 6. With the setting of the compression spring 14, when the pen tip is facing down, the expansion plate 4 can automatically reset. At the same time, the two micro switches 11 move away from each other and automatically wake up the control panel 10, which is convenient for users to use quickly. The control panel 10 is provided on the outer surface of the pen shell 1. Micro switches 11 are provided on the inner bottom wall of the moving cylinder 7 and the bottom end of the insertion rod 6. Both micro switches 11 are electrically connected to the control panel 10. When the pen shell 1 is placed upside down, the counterweight ball 5 pushes the contact plate 9 and the moving sleeve to move with gravity. The two micro switches 11 can move closer to each other, so that the two micro switches 11 make contact and conduction, triggering the control panel 10 to enter sleep mode.

[0031] In this embodiment, a stable reading pen is achieved through a four-way movable expansion plate 4. Compared with the existing two-way sliding plate design, the four circumferentially arranged expansion plates 4 form a symmetrical support surface when inverted, effectively resisting lateral forces from any direction and solving the defect of easy tipping of traditional two-point support. The synergistic effect of the counterweight ball 5 and the micro switch 11 automatically triggers the sleep mode when inverted, solving the problem of power loss caused by users forgetting to turn off the power. The compression spring 14 resets, ensuring that the device is immediately awakened when the pen returns to the normal use posture. It is more reliable than pure electronic sensors and avoids the risk of false triggering.

[0032] The working principle of the above embodiment is as follows: When the reading pen is placed upside down, the metal counterweight ball 5 moves downward under the action of gravity, pushing the contact plate 9 to drive the moving cylinder 7 to slide along the axial direction of the insertion rod 6. The moving cylinder 7 converts the axial movement into the radial expansion of the expansion plate 4 through four hinged connecting rods 8. The four expansion plates 4 expand outward synchronously along the circumferential sliding groove 3, and their unfolded upper surface remains flush with the top of the placement cylinder 2, so that the reading pen forms a four-point symmetrical support structure when it is upside down. Compared with the traditional two-way sliding plate design, the anti-lateral tipping ability is effectively improved. During the downward movement of the moving cylinder 7, the two microswitches 11 installed at the bottom of the insertion rod 6 and the inner bottom wall of the moving cylinder 7 come into contact with each other and conduct. The conduction signal triggers the power management module through the control panel 10, causing it to enter sleep mode and save power. When the user holds the pen shell 1 with the pen tip pointing downward, the counterweight ball 5 disengages from the contact plate 9, and the moving cylinder 7 returns to its original position under the elastic restoring force of the compression spring 14. This action is simultaneously retracted through the connecting rod 8 to the expansion plate 4, and at the same time, the contacts of the microswitches 11 are separated. The switch disconnection signal immediately wakes up the control panel 10.
