Description

Technical Field

[0001] This utility model relates to the field of laser pointer technology, and in particular to a laser pointer. Background Technology

[0002] When troubleshooting network cables, operators usually need to quickly and accurately identify the two ends of the same network cable. Currently, the common method for tracing cables is to add a light-guiding optical fiber to the network cable, then use a laser pointer to shine on one end of the specified cable, and use the optical fiber to make the other end of the cable produce a light spot to identify the other end of the cable.

[0003] However, when laying network cabling, a large number of cables are usually required, which can cause the cables to become tangled together. This makes it difficult for the laser pointer to accurately illuminate the fiber optic cable of the specified cable, reducing the efficiency of cable tracing. Utility Model Content

[0004] The main purpose of this invention is to provide a laser pointer that solves the problem that existing laser pointers are difficult to accurately align with the specified position of the cable when searching for lines, resulting in reduced line searching efficiency.

[0005] To solve the above problems, this utility model proposes a laser pointer, comprising:

[0006] The laser pointer body contains a light source; and

[0007] The laser pointer assembly has one end mounted on one end of the laser pointer body and the other end used to abut against the transmission end of a designated cable. The laser pointer assembly has a transmission channel and is connected to the light source. The transmission channel is used to transmit the laser generated by the light source to the optical fiber of the cable.

[0008] In one embodiment, the emitting needle assembly is detachably connected to the laser pointer body.

[0009] In one embodiment, a first mounting groove is provided at one end of the laser pointer body, and a first through hole is provided at the bottom of the first mounting groove;

[0010] The transmitting pin assembly includes a mounting component, a fixing component, and a transmitting pin. The fixing component has a second through hole. One end of the transmitting pin is connected to the fixing component. The transmitting pin has a transmission channel communicating with the second through hole. The fixing component is disposed in the first mounting groove. The mounting component is fitted onto the fixing component and threaded to the inner wall of the first mounting groove. The other end of the transmitting pin protrudes from the mounting component to abut against the transmission end of a designated cable. The center of the first through hole, the center of the second through hole, and the center of the transmission channel are located on the same axis.

[0011] In one embodiment, the length of the launching needle extending beyond the mounting member is L, wherein 3cm <L<4cm。

[0012] In one embodiment, the laser pointer includes an adjustment plate sandwiched between the bottom of the first mounting groove and the fixing member, for adjusting the alignment of the transmission channel with the first through hole.

[0013] In one embodiment, the light source is a semiconductor light source.

[0014] In one embodiment, the laser pointer body includes a housing, a battery assembly, and a control board. The housing includes a first housing and a second housing, which are detachably connected to form a receiving cavity. The battery assembly, the control board, and the light source are all disposed within the receiving cavity. The light source is at least partially exposed in the second housing. The emitting needle assembly is connected to the second housing. One end of the battery assembly is electrically connected to the control board. The control board is electrically connected to the light source to control the power supply of the light source.

[0015] In one embodiment, the laser pointer body further includes a trigger button. The first housing has a second mounting groove on its end face away from the second housing. The second mounting groove communicates with the receiving cavity. The trigger button is movably disposed in the second mounting groove and electrically connected to the other end of the battery assembly to control the switching of the light source.

[0016] In one embodiment, the laser pointer body further includes a third housing, which is sleeved on the end of the second housing near the light source. The end face of the third housing has the first mounting groove and the first through hole, and the emitting needle assembly is connected to the third housing.

[0017] In one embodiment, the third housing is provided with an anti-slip portion, which is circumferentially disposed on the outer periphery of the third housing;

[0018] And / or, the periphery of the second housing has a plurality of anti-roll surfaces, which are sequentially arranged around the outer periphery of the second housing.

[0019] This invention proposes a laser pointer, comprising a laser pointer body and an emitting needle assembly. The laser pointer body contains a light source, and one end of the emitting needle assembly is mounted on one end of the laser pointer body. When using this laser pointer for cable tracing, because the emitting needle assembly has a certain length and a small diameter, it can be accurately aligned with the designated position of the cable in a complex cable environment. Then, the light source is activated to emit a laser, which is transmitted through a transmission channel to the optical fiber of the cable, causing a light spot to be generated at the other end, thus completing the cable tracing work and improving the cable tracing efficiency.

[0032] When troubleshooting network cables, operators typically need to quickly and accurately identify both ends of the same cable. Currently, the common method involves adding a light-guiding fiber optic cable to the cable and then using a laser pointer to illuminate one end of the cable. The light then travels through the fiber to the other end, creating a spot of light to pinpoint the other end. However, network cabling often involves deploying numerous cables, resulting in tangles and making it difficult for the laser pointer to accurately illuminate the fiber optic cable, thus reducing the efficiency of cable tracing.

[0033] To address the aforementioned problems, this invention proposes a laser pointer that aims to solve the issue that existing laser pointers are difficult to accurately align with the designated position of the cable when searching for lines, resulting in reduced line searching efficiency.

[0034] like Figure 1 and Figure 2 In one embodiment, the laser pointer includes a laser pointer body 10 and a transmitting needle assembly 20. The laser pointer body 10 is provided with a light source (not shown). One end of the transmitting needle assembly 20 is installed at one end of the laser pointer body 10, and the other end is used to abut against the transmission end of a designated cable. The transmitting needle assembly 20 is provided with a transmission channel 231 and is connected to the light source. The transmission channel 231 is used to transmit the laser generated by the light source to the optical fiber of the cable.

[0035] In this embodiment, the laser pointer body 10 is made of a high-strength material, such as stainless steel, to give the laser pointer good durability and drop resistance. The light source is located inside the laser pointer body 10 to emit laser light. The inside of the emitting needle assembly 20 is hollow to form a transmission channel 231. The emitting needle assembly 20 body is a needle-shaped structure with a small diameter and a certain length, so that it can pass through many twisted cables and accurately align with the transmission end of the cable to be searched. The laser emitted by the light source is then transmitted to the optical fiber of the specified cable through the transmission channel 231. The optical fiber transmits the laser to the other end of the cable through its own light guiding properties and generates a light spot. The operator determines the other end of the cable based on the light spot and completes the cable search.

[0036] The laser pointer of this utility model includes a laser pointer body 10 and an emitting needle assembly 20. The laser pointer body 10 is provided with a light source. One end of the emitting needle assembly 20 is installed at one end of the laser pointer body 10. When using this laser pointer for line finding, since the emitting needle assembly 20 has a certain length and a small diameter, it can be accurately aligned to the designated position of the line finding cable in a complex cable environment. Then, the light source is activated to emit a laser. The laser shines through the transmission channel 231 onto the optical fiber of the line finding cable, so that a light spot is generated at the other end, completing the line finding work, thereby improving the line finding efficiency.

[0037] like Figure 1 and Figure 2 In one embodiment, the emitting needle assembly 20 is detachably connected to the laser pointer body 10.

[0038] In this embodiment, the connection between the transmitting needle assembly 20 and the laser pointer body 10 can be a threaded connection, a snap-fit ​​connection, or a magnetic connection, etc. Using these connection methods, when the operator needs to replace the transmitting needle assembly 20, the operator can easily disassemble the old transmitting needle assembly 20 and install the new one. This allows for the selection of different types of transmitting needle assemblies 20 according to different application scenarios and needs, improving the applicability and versatility of the laser pointer. Furthermore, when the transmitting needle assembly 20 is damaged, the operator can disassemble it for repair or replacement without needing to repair or replace the entire laser pointer. This reduces maintenance costs and extends the lifespan of the laser pointer.

[0039] like Figures 1 to 4 In one embodiment, a first mounting groove 131 is provided at one end of the laser pointer body 10, and a first through hole 132 is provided at the bottom of the first mounting groove 131.

[0040] The transmitting needle assembly 20 includes a mounting member 21, a fixing member 22, and a transmitting needle 23. The fixing member 22 has a second through hole 221. One end of the transmitting needle 23 is connected to the fixing member 22. The transmitting needle 23 has a transmission channel 231 that communicates with the second through hole 221. The fixing member 22 is located in the first mounting groove 131. The mounting member 21 is fitted onto the fixing member 22 and threadedly connected to the inner wall of the first mounting groove 131. The other end of the transmitting needle 23 protrudes from the mounting member 21 to abut against the transmission end of a designated cable. The center of the first through hole 132, the center of the second through hole 221, and the center of the transmission channel 231 are located on the same axis.

[0041] In this embodiment, the first mounting groove 131 provides mounting space for the emitting needle assembly 20, and the first through hole 132 is used to transmit the laser generated by the light source to the emitting needle assembly 20.

[0042] The laser pointer assembly 20 includes a mounting component 21, a fixing component 22, and a laser pointer 23. The laser pointer 23 is installed by welding with the fixing component 22 to ensure the stability of the connection between the two. The fixing component 22 is a metal cylinder that serves as the mounting support for the laser pointer 23 and can ensure the installation stability of the laser pointer 23 by its own weight. The laser pointer 23 is a thin stainless steel tube with a hollow interior to form a transmission channel 231. The inner wall is a smooth curved surface to ensure that no reflection occurs when transmitting laser light, thereby improving the positioning accuracy of the laser pointer.

[0043] The mounting component 21 is a frustum-shaped structure. A receiving groove 211 is provided at one end near the laser pointer body 10. The size of the receiving groove 211 is adapted to the size of the fixing component 22. The end away from the laser pointer body 10 serves as a cover part 212. When the emitting needle assembly 20 is installed to the laser pointer body 10, the fixing component 22 is first installed into the receiving groove 211, and the emitting needle 23 passes through the mounting component 21. Then, the emitting needle assembly 20 is installed to the laser pointer body 10 as a whole through the threaded connection between the outer periphery of the receiving groove 211 and the inner wall of the first mounting groove 131. At this time, the cover part 212 covers one end of the laser pointer body 10 to ensure the sealing between the two. After installation, the first through hole 132, the second through hole 221 and the transmission channel 231 are located on the same axis to ensure that the laser can be transmitted in a straight line, thereby improving the positioning accuracy of the laser pointer.

[0044] like Figure 1 and Figure 2 In one embodiment, the length of the launching needle 23 extending out of the mounting member 21 is L, wherein 3cm <L<4cm。

[0045] In this embodiment, the emitting pin 23 extends from the mounting member 21 by a certain length so as to be able to abut against the transmission end of the specified cable. This extended length should not be too short, otherwise, due to the obstruction of the cable to the laser pen body 10, the emitting pin 23 cannot abut against the specified position. At the same time, this extended length should not be too long, otherwise, it is easy for the emitting pin 23 to bend and break. In this embodiment, the length that the emitting pin 23 extends from the mounting member 21 is L, where 3 cm < L < 4 cm. For example, L can be 3.1 cm, 3.3 cm, 3.5 cm, 3.7 cm, etc. At this time, the emitting pin 23 has sufficient length to abut against the specified position of the cable and has relatively high structural stability.

[0046] Such as Figure 1 and Figure 2 , in one embodiment, the laser pen includes an adjusting piece which is clamped between the bottom of the first mounting groove 131 and the fixing member 22 for adjusting the alignment of the transmission channel 231 and the first through hole 132.

[0047] In this embodiment, the adjusting piece (not shown) can be a rubber piece installed between the bottom of the first mounting groove 131 and the fixing member 22. When it is found that there is a deviation in the coaxiality between the transmission channel 231 and the first through hole 132, the emitting pin 23 can be slightly shaken. By the elastic deformation of the adjusting piece, the position of the fixing member 22 is adjusted, and then the position of the emitting pin 23 is adjusted so that the transmission channel 231 and the first through hole 132 are coaxial again. The setting of this adjusting piece can accurately adjust the transmission path of the laser, thereby improving the performance and reliability of the entire system.

[0048] Such as Figure 2 , in one embodiment, the light source is a semiconductor light source.

[0049] In this embodiment, the type of the light source is a semiconductor light source. The semiconductor light source has a small volume, so it is convenient to be integrated in the internal space of the laser pen, reducing the overall volume of the laser pen. At the same time, the semiconductor light source has a long service life and can work stably for a long time, reducing the frequency of replacing the light source, and thus improving the service life of the laser pen.

[0050] In other embodiments, the light source can also be a fixed laser or a fiber laser, etc.

[0051] Such as Figures 1 to 5In one embodiment, the laser pointer body 10 includes a housing, a battery assembly, and a control board. The housing includes a first housing 11 and a second housing 12. The first housing 11 and the second housing 12 are detachably connected to form a receiving cavity. The battery assembly, the control board, and the light source are all disposed in the receiving cavity. The light source is at least partially exposed in the second housing 12. The emitting needle assembly 20 is connected to the second housing 12. One end of the battery assembly is electrically connected to the control board. The control board is electrically connected to the light source to control the power supply of the light source.

[0052] In this embodiment, the battery assembly is a replaceable battery. Both the first housing 11 and the second housing 12 are hollow, forming a cavity to house the battery assembly, control board, and light source. The first housing 11 and the second housing 12 are connected by a threaded connection, ensuring connection stability while facilitating disassembly for battery assembly replacement, thus improving the laser pointer's practicality. Part of the light source is installed inside the second housing 12, while the other part is exposed outside, maximizing light utilization while ensuring installation stability. When the laser pointer is in operation, the battery assembly sends a signal to the control board. Upon receiving the signal, the control board immediately controls the light source's on / off state, thus enabling the laser pointer's on / off function. This simple operation further enhances the laser pointer's ease of use.

[0053] like Figure 1 and Figure 5 In one embodiment, the laser pointer body 10 further includes a trigger key 30. The end face of the first housing 11 facing away from the second housing 12 is provided with a second mounting groove 111. The second mounting groove 111 communicates with the receiving cavity. The trigger key 30 is movably disposed in the second mounting groove 111 and electrically connected to the other end of the battery assembly to control the switching of the light source.

[0054] In this embodiment, a second mounting groove 111 is provided on the first housing 11 to accommodate a trigger button 30. The trigger button 30 is a flexible button and is movably disposed within the second mounting groove 111. The operator can activate or deactivate the laser pointer by pressing the trigger button 30. When the trigger button 30 is pressed, it triggers the internal circuitry, thereby controlling the battery assembly to send a signal to the control board. Upon receiving the signal, the control board controls the start and stop of the light source, realizing the on / off function of the laser pointer. This design of the trigger button 30 makes the operation of the laser pointer simpler and improves its flexibility. At the same time, the axial length of the trigger button 30 is less than or equal to the groove depth of the second mounting groove 111 to prevent the trigger button 30 from protruding from the second mounting groove 111 and causing accidental activation, thereby improving the lifespan of the laser pointer.

[0055] like Figure 1In one embodiment, the laser pointer body 10 further includes a third housing 13, which is sleeved on the end of the second housing 12 near the light source. The end face of the third housing 13 is provided with a first mounting groove 131 and a first through hole 132, and the emission needle assembly 20 is connected to the third housing 13.

[0056] In this embodiment, the laser pointer also includes a third housing 13, with the light source located inside the third housing 13 to prevent the light source from being affected by the external environment, thereby ensuring the stability and reliability of the laser pointer. The third housing 13 is connected to the second housing 12 by a threaded connection, which facilitates the replacement or cleaning of the internal light source and improves the practicality of the laser pointer.

[0057] like Figure 1 In one embodiment, the third housing 13 includes an anti-slip portion 133, which is circumferentially disposed on the outer periphery of the third housing 13;

[0058] And / or, the second housing 12 has a plurality of anti-roll surfaces 121 on its periphery, and the plurality of anti-roll surfaces 121 are arranged in sequence around the outer periphery of the laser pen body 10.

[0059] In this embodiment, the anti-slip part 133 is composed of multiple linear protrusions and is arranged around the outer periphery of the third housing 13. The anti-slip part 133 can enhance the friction force, facilitate the disassembly between the third housing 13 and the second housing 12, and improve the grip comfort and anti-slip performance of the laser pointer.

[0060] With or without the above embodiments, the second housing 12 includes a plurality of anti-roll surfaces 121. By connecting the ends of the plurality of anti-roll surfaces 121, a plurality of protruding ridges are formed on the outer periphery of the second housing 12, thereby preventing the laser pointer from rolling from a flat surface to the ground and causing damage, and improving the service life of the laser pointer.

[0061] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
