Description

Technical Field

[0001] The utility model relates to the technical field of teaching and office appliances, in particular to a telescopic writing laser pointer. Background Art

[0002] Electronic whiteboards and all-in-one machines have become the most mainstream devices in current information-based teaching. The electronic whiteboard replaces the function of the traditional blackboard and integrates functions such as courseware display and blackboard writing. During the teaching process using the electronic whiteboard by teachers, two auxiliary devices are often used, namely a whiteboard writing pen and a laser pointer. The function of the whiteboard writing pen is mainly to write on the whiteboard, and the function of the laser pointer is mainly to guide the teaching content and prompt students to pay attention to the knowledge points.

[0003] In the traditional technology, the whiteboard writing pen and the laser pointer are two different and independent devices. However, blackboard writing and laser indication are teaching behaviors that often alternate during the teaching process. Teachers need to frequently switch between the whiteboard writing pen and the laser pointer, which is not only time-consuming and laborious but also prone to causing inconvenience in teaching. Summary of the Utility Model

[0004] The utility model provides a telescopic writing laser pointer with two functions of writing and laser indication, effectively solving the technical problems raised in the above background art.

[0005] The utility model provides the following technical solutions.

[0006] A telescopic writing laser pointer includes a main rod body, a writing pen body, a tail end cap, a laser pen body, and a holding sleeve. The main rod body is hollow inside and both ends are through. The writing pen body is inserted on one side inside the main rod body, and the pen tip of the writing pen body protrudes from the head of the main rod body to the outside. The tail end cap is provided at the tail of the main rod body. One side of the tail end cap away from the main rod body has an installation opening, and the laser pen body is embedded and installed in the installation opening. One end of the holding sleeve has an opening and the other end is sealed. A through screw hole is provided at the sealed end of the holding sleeve. A second external thread portion adapted to the screw hole is provided on the outer wall of the main rod body near its head. The holding sleeve is sleeved on the main rod body, and the screw hole is threadedly matched and connected with the second external thread portion.

[0007] Furthermore, the writing pen body further includes a pen core connected to the pen tip. Ink is stored inside the pen core for supplying ink to the pen tip. An annular mounting seat is fixed on the inner wall of the main rod body near its head. A through threaded mounting hole is provided at the center of the annular mounting seat. The outer surface of the pen core is provided with a first external thread portion adapted to the threaded mounting hole. The pen core is inserted through and mounted on the annular mounting seat through the threaded mounting hole and the first external thread portion in a threadedly matched manner.

[0008] Furthermore, a bayonet is provided on one side of the tail end cap away from the laser pen body, and a buckle part adapted to the bayonet is provided at the tail of the main rod body, and the bayonet of the tail end cap can be matched and buckled on the buckle part at the tail of the main rod body.

[0009] Furthermore, the telescopic writing laser pen also includes a multi-stage damping telescopic rod, one end of which is fixed inside the main rod body, and the other end extends straight into the bayonet and is fixed to the inner end wall of the bayonet. The end face of the multi-stage damping telescopic rod located inside the main rod body blocks and cooperates with the end of the pen core away from the pen tip.

[0010] Furthermore, a weight ring is fixedly mounted on the outer surface of the holding sleeve and on one side away from the tail end cap, and the end of the weight ring is kept flush with the end surface of the holding sleeve away from the tail of the main rod body.

[0011] Furthermore, anti-slip grooves are provided on the outer wall of the holding sleeve, and a retaining ring is fixed on the outer wall of the main rod body near its head. The diameter of the retaining ring is larger than the inner diameter of the screw hole and smaller than the inner hole diameter of the holding sleeve. The retaining ring and the inner end wall of the sealing end of the holding sleeve are blocked and cooperated.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows.

[0013] 1. The utility model integrates the writing pen body and the laser pen body on the main rod body, so that the telescopic writing laser pen has both writing and laser pointing functions. Compared with the traditional independent writing pen and laser pen, the whiteboard writing and laser pointing functions can be used alternately during the teaching process, without the need to frequently switch between the independent writing pen and laser pen, which saves time and effort and greatly facilitates the continuity of the teaching process.

[0014] 2. When the utility model holds the holding sleeve tightly for writing, the contact area between the holding sleeve and the hand is larger, and thus the friction force is greater, the grip is more stable, and the writing is convenient. When idle, the holding sleeve is twisted to slide to the side away from the tail end cap until the pen tip is covered to achieve storage of the pen tip. In addition, the bottom end of the holding sleeve away from the tail end cap is placed on a flat surface, and the entire telescopic writing laser pen can be directly placed upright to avoid random rolling when placed due to the round shape of the entire pen body. The holding sleeve serves as both a holding component and a component for storing the pen tip, and at the same time as a placement seat, achieving multiple goals at one stroke and high practicality.

[0015] 3. The writing pen body of the utility model is equipped with multiple refills, and the refills are screwed on the annular mounting seat, which has a detachable effect. After the ink in the writing pen body is used up, the refills can be unscrewed from the annular mounting seat for replacement to ensure that the whole has a long service life. In addition, the threaded screwing method makes the disassembly and assembly of the writing pen body convenient enough, and the replacement operation is convenient.

[0016] 4. The utility model connects the main rod body and the tail end cap by using a multi-stage damping telescopic rod, enabling the whole to have the effect of telescopic adjustment. By stretching the multi-stage damping telescopic rod, the overall length can be extended. On the one hand, it can be used as a pointer, and on the other hand, it is convenient for teachers with shorter heights to use, killing two birds with one stone. Moreover, the telescopic adjustment of the multi-stage damping telescopic rod has a damping effect. When not adjusted manually, the multi-stage damping telescopic rod will not stretch or contract randomly, which helps to maintain the overall length and is convenient for use.

[0026] Please refer to Figures 1-4 , a telescopic writing laser pen provided by the present utility model includes a main rod body 1, a writing pen body 2, a tail end cap 3, a laser pen body 4, and a holding sleeve 5. The main rod body 1 is hollow inside and through at both ends. The writing pen body 2 is inserted on one side inside the main rod body 1, and the tip 21 of the writing pen body 2 protrudes from the head of the main rod body 1 to the outside. The tail end cap 3 is provided at the tail of the main rod body 1. The side of the tail end cap 3 away from the main rod body 1 has an installation opening 32. The laser pen body 4 is embedded and installed in the installation opening 32. One end of the holding sleeve 5 has an opening, and the other end is sealed. The sealed end of the holding sleeve 5 is provided with a through screw hole 51. On the outer wall of the main rod body 1, a second external thread portion 52 adapted to the screw hole 51 is provided on one side near its head. The holding sleeve 5 is sleeved on the main rod body 1, and the screw hole 51 is threadedly matched and connected with the second external thread portion 52.

[0027] The telescopic writing laser pen provided by the present utility model installs the writing pen body 2 on one side inside the main rod body 1, arranges the laser pen body 4 in the tail end cap 3 on the other side of the main rod body 1. By screwing and adjusting the holding sleeve 5, under the threaded driving action of the screw hole 51 and the second external thread portion 52, the holding sleeve 5 can be driven to slide left and right along the writing pen body 2 for adjustment. When the holding sleeve 5 completely moves onto the writing pen body 2, the tip 21 can be exposed from the port of the holding sleeve 5 to the outside. Holding the holding sleeve 5, normal writing can be carried out using the tip 21. In addition, when idle, by screwing the holding sleeve 5 in the reverse direction, the holding sleeve 5 slides to the side away from the tail end cap 3 until the tip 21 is covered, so as to realize the storage of the tip 21 and avoid the tip 21 directly contacting the ground and being damaged when dropped. In addition, when idle and the tip 21 is stored in the holding sleeve 5, placing the bottom end of the side of the holding sleeve 5 away from the tail end cap 3 against a plane can directly place the entire telescopic writing laser pen vertically, avoiding the entire pen body rolling randomly due to its circular shape during placement.

[0028] When laser indication is needed, the laser pen body 4 is turned on by pressing the control switch arranged on the tail end cap 3, and the light emitted by the laser pen body 4 can be used for indication. In addition, the laser pen body 4 is embedded in the installation port 32 to prevent the laser pen body 4 from directly contacting the ground and being damaged when it falls.

[0029] The writing pen body 2 and the laser pen body 4 of this telescopic writing laser pen are integrally arranged on the main rod body 1, so that this telescopic writing laser pen has both writing and laser indication functions. Compared with traditional independent writing pens and laser pens, it can alternately use the whiteboard writing and laser indication functions during the teaching process, without the need to frequently switch between the independent writing pen and the laser pen, saving time and effort, and greatly facilitating the continuity of the teaching process.

[0030] When the holding sleeve 5 is tightly held for writing, the contact area between the holding sleeve 5 and the hand is larger, and thus the friction force is greater, making the grasping more stable and convenient for writing. When it is idle, the holding sleeve 5 is rotated to slide away from the tail end cap 3 until the pen tip 21 is covered, realizing the storage of the pen tip 21. In addition, when the bottom end of the side of the holding sleeve 5 away from the tail end cap 3 is placed against a plane, the entire telescopic writing laser pen can be directly placed vertically, avoiding random rolling during placement due to the circular shape of the entire pen body. The holding sleeve 5 serves as both a holding component, a component for storing the pen tip 21, and a placement seat, achieving multiple functions with one action and having high practicality.

[0031] Specifically, the writing pen body 2 further includes a pen core 22 connected to the pen tip 21. The pen core 22 stores ink inside for supplying ink to the pen tip 21. A circular mounting seat 221 is fixed on the inner wall of the main rod body 1 near its head. A threaded mounting hole 222 is provided at the center of the circular mounting seat 221. The outer surface of the pen core 22 is provided with a first external thread portion 223 adapted to the threaded mounting hole 222. The pen core 22 is inserted through the circular mounting seat 221 in a threaded matching manner through the threaded mounting hole 222 and the first external thread portion 223. The writing pen body 2 is a consumable part. In this utility model, multiple writing pen bodies 2 are provided. At the same time, the pen core 22 is screwed onto the circular mounting seat 221, having a detachable effect. After the ink in the writing pen body 2 is used up, the pen core 22 can be unscrewed from the circular mounting seat 221 for replacement to ensure the overall long service life. In addition, the threaded mounting method makes the disassembly and assembly of the writing pen body 2 convenient enough and the replacement operation is easy.

[0032] Specifically, a bayonet 31 is provided on the side of the tail end cap 3 away from the laser pen body 4, and a buckle portion 311 adapted to the bayonet 31 is provided at the tail of the main rod body 1. The bayonet 31 of the tail end cap 3 can be matched and buckled on the buckle portion 311 at the tail of the main rod body 1.

[0033] This telescopic writing laser pointer further includes a multi-stage damping telescopic rod 6. One end of the multi-stage damping telescopic rod 6 is fixed inside the main rod body 1, and the other end extends into the straight bayonet 31 and is fixed to the inner end wall of the bayonet 31. The end face of the multi-stage damping telescopic rod 6 located inside the main rod body 1 is in blocking cooperation with the end of the pen core 22 away from the pen tip 21, so as to prevent the pen tip 21 from being retracted into the main rod body 1 due to excessive screwing of the pen core 22, making it difficult to disassemble.

[0034] The main rod body 1 and the tail end cap 3 are connected by the multi-stage damping telescopic rod 6, enabling the overall to have the effect of telescopic adjustment. By exerting force to remove the tail end cap 3 from the buckle part 311 and stretching the multi-stage damping telescopic rod 6, the overall length can be extended. On the one hand, it can be used as a pointer, and on the other hand, it is convenient for teachers with shorter heights to use, killing two birds with one stone. Moreover, the telescopic adjustment of the multi-stage damping telescopic rod 6 has a damping effect. When not adjusted manually, the multi-stage damping telescopic rod 6 will not extend or retract randomly, which helps to maintain the overall length and is convenient for use.

[0035] In addition, when the multi-stage damping telescopic rod 6 retracts and the overall is stored, by using the snap-fit of the bayonet 31 and the snap part 311, the tail end cap 3 can be snap-fitted to the tail of the main rod body 1 to maintain the integrity of the overall.

[0036] Specifically, a counterweight ring 54 is fixedly sleeved on the outer surface of the holding sleeve 5 and on the side away from the tail end cap 3. The end of the counterweight ring 54 is flush with the end face of the holding sleeve 5 away from the tail of the main rod body 1. When the overall is placed vertically, by adding the counterweight ring 54 at the end of the holding sleeve 5, the overall center of gravity is lowered. At the same time, the combination of the holding sleeve 5 and the end face of the counterweight ring 54 has a larger contact area with the placement surface, thereby ensuring the stability when the overall is placed vertically.

[0037] Specifically, anti-slip patterns 501 are provided on the outer wall of the holding sleeve 5, and a retaining ring 53 is fixed on the outer wall of the main rod body 1 near its head. The diameter of the retaining ring 53 is larger than the inner diameter of the screw hole 51 and smaller than the inner diameter of the holding sleeve 5. The retaining ring 53 is in blocking cooperation with the inner end wall of the sealing end of the holding sleeve 5. By using the blocking cooperation between the retaining ring 53 and the inner end wall of the sealing end of the holding sleeve 5, an anti-detachment effect is achieved, preventing the holding sleeve 5 from being unscrewed excessively to the side away from the tail of the main rod body 1 and falling off the main rod body 1.

[0038] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention; without conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
