Description
Technical Field
[0001] The utility model relates to the technical field of pointer pen, in particular to a novel pointer pen. Background Art
[0002] Laser pointer, also known as electronic pointer, laser pointer or star pointer, is a kind of pointer pen. Laser pointer is a new patented electronic product specially designed for computers and multimedia projectors.
[0003] The laser pointer consists of an RF remote control and a receiver (USB port). The RF remote control has an embedded wireless RF transmitter. Simply plug the receiver into the computer's USB port to operate it; no driver installation is required. Users simply click the relevant function keys on the RF remote control to control the receiver. Furthermore, the transmitter doesn't need to be aligned with the receiver, offering true wireless freedom. To improve teaching efficiency and quality, more and more teachers are adopting multimedia courses, and laser pointers are widely used in multimedia teaching (such as English and mathematics).
[0004] Laser pointers in the existing general technology (excluding the receiver) typically include a pen body, a laser light located at one end of the pen body, a battery located within the pen body, an RF remote control located within the pen body, and function buttons located within the pen body and electrically connected to the laser light and RF remote control. To facilitate the use of laser pointers, teachers typically do not remove the battery after use. Because the function buttons are located directly on the pen body, they are easily accidentally pressed when the user is carrying or storing the laser pointer. The function buttons include buttons for turning the laser light on or off. Accidentally pressing a function button and turning the laser light on accelerates battery drain, shortening the battery life. Furthermore, the function buttons are push-button-type, and repeated accidental pressing can affect the life of the function buttons (including the function indicator on the function buttons). Therefore, improvements to laser pointers in the related art are needed. Utility Model Content
[0005] In order to solve the above problems, the utility model provides a novel pointer pen.
[0006] The above technical purpose of the present utility model is achieved through the following technical solutions: a new type of pointer pen, including a pen body, a laser light arranged at one end of the pen body, a battery arranged in the pen body, an RF radio frequency remote control arranged in the pen body, and a function button arranged on the pen body and electrically connected to the laser light and the RF radio frequency remote control, the outer wall of the pen body is provided with an annular mounting groove, the function button is located in the annular mounting groove, a protective sleeve is movably provided in the annular mounting groove, which can rotate around the axis of the annular mounting groove and is used to protect the function button, an operation window is provided at the position of the protective sleeve corresponding to the function button, and a fixing component for fixing to the pen body is provided on the protective sleeve.
[0007] By adopting the above technical solution, when using the pointer pen, the user only needs to rotate the protective sleeve so that the operation window and the function keys are opposite each other, and fix the protective sleeve with the fixing component, so that the user can operate the function keys through the operation window. When the pointer pen is not in use, the user needs to rotate the protective sleeve so that the operation window and the function keys are misaligned, and fix the protective sleeve with the fixing component, so that the protective sleeve can cover the function keys. This solves the problem of the traditional technology that the function keys are easily accidentally touched when the pointer pen is not in use, which affects the battery life and the life of the function keys, and is conducive to extending the service life of the pointer pen.
[0008] Furthermore, the pen body includes a first pen barrel and a second pen barrel, a threaded sleeve is integrally formed at one end of the first pen barrel, a threaded hole is provided on the inner wall of one end of the second pen barrel, and the ends of the first pen barrel and the second pen barrel that are away from each other are both closed, the laser light is located at the end of the first pen barrel away from the second pen barrel, the battery is arranged in the first pen barrel and the second pen barrel, the annular mounting groove is located on the outer wall of the first pen barrel, a first annular groove is provided on the top wall of the annular mounting groove, a first annular block is integrally formed at one end of the protective sleeve to be plugged into and matched with the first annular groove, a second annular groove is provided at a position corresponding to the first annular groove at the end of the second pen barrel close to the laser light, and a second annular block is integrally formed at the other end of the protective sleeve to be plugged into and matched with the second annular groove;
[0009] The outer wall of the second annular block is provided with a mounting hole, and the fixing assembly includes a spring fixed to the inner wall of the mounting hole close to the second pen shaft axis and a fixing piece fixed to the free end of the spring, the fixing piece slidingly cooperates with the mounting hole, and the end of the fixing piece away from the spring is hemispherical, and the outer wall of the second annular groove is provided with a hemispherical groove that cooperates with the hemispherical part of the fixing piece. There are two hemispherical grooves, one of which is located directly below the function key.
[0010] By adopting the above technical solution, the first and second pen bodies are threadedly connected to the threaded holes via threaded sleeves, facilitating user battery installation and replacement. One end of the protective sleeve engages with the first annular groove via a first annular block, while the other end engages with the second annular groove via a second annular block. This allows the protective sleeve to rotate during use, thereby shielding the function keys or exposing them for operation. Under the elastic force of the spring, the hemispherical portion of the fixing member engages with the hemispherical groove directly below the function keys, securing the protective sleeve to the second pen body. In this case, the operating window aligns with the position of the function keys, ensuring the stability of the protective sleeve during user operation of the function keys. When the hemispherical portion of the fixing member engages with another hemispherical groove (not directly below the function keys), the protective sleeve is also secured to the second pen body. In this case, the operating window is offset from the function keys, ensuring that the pointer pen protects the function keys when not in use.
[0011] Furthermore, a plurality of anti-slip ridges are fixed to the outer wall of the protective sleeve, and the extending direction of the anti-slip ridges is parallel to the axial direction of the protective sleeve.
[0012] By adopting the above technical solution, the provision of the anti-slip ridges increases the friction between the user's hand and the outer wall of the protective sleeve, so that the user can rotate the protective sleeve so that the hemispherical portion of the fixing part engages with the hemispherical groove directly below the function key or another hemispherical groove, so as to expose the function key for operation or cover the function key for protection.
[0013] Furthermore, an upper indicating groove is provided on the outer wall of the protective sleeve at a position corresponding to the fixing piece, and a lower indicating groove is provided on the second pen shaft at a position corresponding to the hemispherical groove, and there are two of each of the upper indicating groove and the lower indicating groove.
[0014] By adopting the above technical solution, when the user rotates the protective sleeve so that the two upper indicator grooves correspond to the positions of the two lower indicator grooves respectively, the operation window just corresponds to the function key. At this time, it is convenient for the user to control the pointer pen through the function key. The upper indicator groove and the lower indicator groove cooperate to play a good indicating role, so that the user can quickly rotate the protective sleeve, thereby achieving the purpose of quickly exposing the function key and operating it or quickly covering the function key and protecting it.
[0015] Furthermore, a hook is fixed on the outer wall of the second pen barrel at a position away from one end of the first pen barrel.
[0016] By adopting the above technical solution and setting the hook, the user can hang the pointer pen in the pocket of the coat, thereby enhancing the portability of the pointer pen.
[0017] Furthermore, the function keys include a control button arranged on the outer wall of the annular mounting groove and used to control the laser light, an up key arranged on the outer wall of the annular mounting groove and used to control turning pages upward, and a down key arranged on the outer wall of the annular mounting groove and used to control turning pages downward.
[0018] By adopting the above technical solution, the setting of the control button is convenient for the user to control the laser light to turn on or off. The up key and the down key are used to control the courseware to turn up or down the page respectively.
[0019] In summary, the present invention has the following beneficial effects:
[0020] 1. This application solves the problem in the traditional technology that the function keys are easily accidentally touched when the pointer pen is not in use, which affects the battery life and the life of the function keys, and is conducive to extending the service life of the pointer pen;
[0021] 2. In this application, under the elastic force of the spring, when the hemispherical portion of the fixing member engages with the hemispherical groove directly below the function key, the protective sleeve and the second pen holder are fixed. At this time, the operation window and the function key are aligned, ensuring the stability of the protective sleeve when the user operates the function key. When the hemispherical portion of the fixing member engages with another hemispherical groove (not directly below the function key), the protective sleeve and the second pen holder are also fixed. At this time, the operation window and the function key are offset, ensuring that the pointer pen protects the function key when not in use.
[0022] 3. In the present application, the provision of the anti-slip ridges increases the friction between the user's hand and the outer wall of the protective sleeve, so that the user can rotate the protective sleeve so that the hemispherical portion of the fixing part engages with the hemispherical groove directly below the function key or another hemispherical groove, so as to expose the function key and operate it or cover the function key and protect it.

Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.
[0032] like Figure 1-7 As shown, the embodiment of the present application discloses a novel pointer pen, comprising a pen body 1, a protective sleeve 2, and a fixing assembly 3. The pen body 1 comprises a first pen shaft 11 and a second pen shaft 12. A threaded sleeve 111 is integrally formed at one end of the first pen shaft 11, and a threaded hole 121 is provided on the inner wall of one end of the second pen shaft 12 for threaded connection with the threaded sleeve 111. The ends of the first pen shaft 11 and the second pen shaft 12 that are away from each other are both closed.
[0033] A laser light 112 is provided at one end of the first pen shaft 11 away from the second pen shaft 12, and a battery 4 is provided in both the first pen shaft 11 and the second pen shaft 12. An RF remote control 5 is provided in the first pen shaft 11 near the laser light 112 (with a built-in wireless RF transmitter. When in use, it only requires inserting the matching receiver into the USB port of the computer host. It can work normally without installing a driver. The user only needs to click the relevant function keys of the RF remote control 5 to operate the receiver. This part belongs to the existing technology and there is no need to elaborate further).
[0034] An annular mounting groove 113 is provided on the outer wall of the first pen body 11 near the second pen body 12. A function button 6 electrically connected to the laser light 112 and the RF remote control 5 is provided in the annular mounting groove 113. The function button 6 includes a control button 61 provided on the outer wall of the annular mounting groove 113 and used to control the laser light 112, an up key 62 provided on the outer wall of the annular mounting groove 113 and used to control turning pages upward, and a down key 63 provided on the outer wall of the annular mounting groove 113 and used to control turning pages downward.
[0035] The protective sleeve 2 is mounted on the first pen body 11 and positioned within the annular mounting groove 113. The protective sleeve 2 can rotate about the axis of the annular mounting groove 113 and is used to protect the function buttons 6. An operating window 21 is provided on the protective sleeve 2 at a position corresponding to the function buttons 6. In this embodiment, a first annular groove 114 is provided on the top wall of the annular mounting groove 113. A first annular block 22 is integrally formed on one end of the protective sleeve 2 to engage with the first annular groove 114. A second annular groove 122 is provided on the end of the second pen body 12 near the laser light 112, corresponding to the first annular groove 114. A second annular block 23 is integrally formed on the other end of the protective sleeve 2 to engage with the second annular groove 122.
[0036] The outer wall of the second annular block 23 is provided with a mounting hole 231. The fixing assembly 3 is mounted on the protective sleeve 2 and is used to secure the pen body 1. The fixing assembly 3 includes a spring 31 fixed to the inner wall of the mounting hole 231 near the axis of the second pen body 12, and a fixing member 32 fixed to the free end of the spring 31. The fixing member 32 slidably engages with the mounting hole 231. The end of the fixing member 32 away from the spring 31 is hemispherical. The outer wall of the second annular groove 122 is provided with a hemispherical groove 123 that mates with the hemispherical portion of the fixing member 32. There are two hemispherical grooves 123, one of which is located directly below the function button 6. The first and second pen bodies 11 and 12 are threadedly connected to the threaded hole 121 via a threaded sleeve 111, allowing the user to install and replace the battery 4. One end of the protective sleeve 2 engages with the first annular groove 114 via a first annular block 22, while the other end engages with the second annular groove 122 via a second annular block 23. This allows the protective sleeve 2 to rotate during use, either shielding the function button 6 or exposing it for operation. Under the elastic force of the spring 31, the hemispherical portion of the fixing member 32 engages with the hemispherical groove 123 directly below the function button 6, securing the protective sleeve 2 to the second pen holder 12. At this point, the operating window 21 aligns with the position of the function button 6, ensuring the stability of the protective sleeve 2 while the user manipulates the function button 6. When the hemispherical portion of the fixing member 32 engages with the other hemispherical groove 123 (not directly below the function button 6), the protective sleeve 2 is also secured to the second pen holder 12. At this point, the operating window 21 is offset from the function button 6, ensuring the pointer pen protects the function button 6 when not in use.
[0037] In order to enhance the fixing effect of the protective sleeve 2, the upper end of the protective sleeve 2 is also connected to the first pen body 11 near the first annular groove 114 through a fixing component 3. The connection method between the upper end of the protective sleeve 2 and the first pen body 11 is the same as the connection method between the lower end of the protective sleeve 2 and the second pen body 12. In addition, two hemispherical grooves 123 are also provided on the first pen body 11, and a mounting hole 231 is also provided on the first annular block 22.
[0038] To reduce the chance of slipping when the user rotates the protective sleeve 2, a plurality of anti-slip ridges 24 are fixed to the outer wall of the protective sleeve 2. The anti-slip ridges 24 extend parallel to the axial direction of the protective sleeve 2. To facilitate the user's rapid rotation of the protective sleeve 2 so that the operation window 21 aligns with or is misaligned with the function button 6, an upper indicator groove 25 is provided on the outer wall of the protective sleeve 2 at a position corresponding to the fixing member 32, and a lower indicator groove 124 is provided on the second pen shaft 12 at a position corresponding to the hemispherical groove 123. Two upper indicator grooves 25 and two lower indicator grooves 124 are provided. When the user rotates the protective sleeve 2 so that the two upper indicator grooves 25 correspond to the two lower indicator grooves 124, the operation window 21 coincides with the function button 6. This facilitates the user's control of the pointer pen through the function button 6. The upper indicator grooves 25 and the lower indicator grooves 124 cooperate to provide a good indicator, allowing the user to quickly rotate the protective sleeve 2, thereby quickly exposing the function button 6 for operation or quickly shielding the function button 6 for protection.
[0039] In order to improve the portability of the pointer pen, a hook 7 is fixed to the outer wall of the second pen barrel 12 at a position away from one end of the first pen barrel 11, so that the user can hang the pointer pen in a coat pocket.
[0040] The operating principle of the new pointer pen in this embodiment is as follows: the first pen body 11 and the second pen body 12 are threadedly connected to the threaded hole 121 via the threaded sleeve 111, so that the user can install and replace the battery 4. One end of the protective sleeve 2 is plugged into the first annular groove 114 via the first annular block 22, and the other end of the protective sleeve 2 is plugged into the second annular groove 122 via the second annular block 23, so that the protective sleeve 2 can rotate during use, thereby shielding the function button 6 for protection or exposing the function button 6 for operation. Under the elastic force of the spring 31, when the hemispherical portion of the fixing member 32 engages with the hemispherical groove 123 directly below the function button 6, the protective sleeve 2 and the second pen body 12 are fixed. At this time, the operation window 21 corresponds to the position of the function button 6, ensuring the stability of the protective sleeve 2 when the user operates the function button 6. When the hemispherical portion of the fixing member 32 cooperates with another hemispherical groove 123 (not directly below the function key 6), the protective sleeve 2 and the second pen body 12 are also fixed. At this time, the operating window 21 and the function key 6 are misaligned, ensuring that the pointer pen protects the function key 6 when not in use.
