Detailed Implementation

[0030] The existing laser pointers have overly simple opening mechanisms, posing a safety hazard that children can easily turn them on, as well as the risk of eye injury to unrelated people in the vicinity.

[0031] To address the aforementioned issues, this invention provides a laser pointer that effectively prevents children from easily opening it by combining threaded locking and sliding locking mechanisms, thereby significantly improving the safety hazards caused by the simple opening mechanism.

[0037] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0038] The overall structure, working principle, and technical effects of the laser pointer 10 provided by this utility model are described in detail below with reference to embodiments and accompanying drawings. Please refer to... Figures 1 to 6 ,in, Figures 1 to 3 The attached diagram shows the disassembly structure in a locked state. Figures 4 to 6 The attached diagram shows the disassembly structure in the unlocked state.

[0039] This invention provides a laser pointer 10, applicable to laser pointers, which effectively prevents children from easily opening the laser pointer by combining a threaded locking and a sliding locking mechanism, thereby significantly improving the safety hazards caused by the simple opening mechanism of existing laser pointers. It is understood that this laser pointer 10 can also be applied to other products with detachable structures, which will not be elaborated here.

[0040] The laser pointer 10 includes a housing 100, a cover 300, and a sliding assembly 500. The housing 100 has a through hole 110 extending along a first direction 910. The sliding assembly 500 slides within the through hole 110, allowing it to reciprocate along the first direction 910. The cover 300 is threadedly connected to the housing 100, forming a preliminary connection. Since the cover 300 also has a groove 310 communicating with the through hole 110 in the first direction 910, the position of the sliding assembly 500 can be adjusted to lock the housing 100 and the cover 300 together. That is, when the sliding assembly 500 is simultaneously within both the groove 310 and the through hole 110, the housing 100 and the cover 300 are locked, effectively limiting relative rotation between them.

[0041] Based on the above configuration, when it is necessary to lock the outer shell 100 and the cover 300, the cover 300 is first screwed onto the outer shell 100 via a threaded connection, forming a preliminary connection through rotation. Subsequently, the sliding component 500 is pushed to move along the through hole 110 towards the groove 310 until a portion of the sliding component 500 simultaneously enters both the groove 310 and the through hole 110. At this point, the engagement between the sliding component 500 and the groove 310 restricts the rotational freedom of the outer shell 100 and the cover 300, achieving a reliable locking effect.

[0042] When it is necessary to unlock the outer shell 100 from the cover 300, first push the sliding component 500 in the opposite direction so that it exits from the groove 310 and remains completely within the through hole 110. At this time, the interlocking effect between the sliding component 500 and the groove 310 is released, and the outer shell 100 and the cover 300 can rotate relative to each other. Finally, by rotating the cover 300 counterclockwise, the threaded connection can be disengaged, and the outer shell 100 and the cover 300 can be separated.

[0043] Please see Figure 3 and Figure 6The sliding assembly includes a slider 510, which extends along a first direction 910 to form a rib 511. The rib 511 slides and engages with the through hole 110 and the groove 310, thereby locking the outer shell 100 and the cover 300 and restricting their relative rotation. It should be noted that the shape of the rib 511 can be rectangular or an irregular polygon, as long as it engages with the groove 310; this embodiment is not limited to this.

[0044] To facilitate user application of force, the sliding assembly 500 also includes a trigger 530 connected to the slider 510. The trigger 530 extends along a second direction 930 perpendicular to the first direction 910 and passes through the through hole 110. Based on this, the user can control the movement of the slider 510 by directly operating the trigger 530, thereby realizing the locking or unlocking function of the housing 100 and the cover 300.

[0045] Furthermore, the hole wall on the upper side of the through hole 110 extends inward to form a limiting part 130. The limiting part 130 is used to stop the trigger 530 when the rib 511 and the groove 310 are engaged, that is, to control the movement stroke of the trigger 530, thereby effectively avoiding functional failure or structural damage caused by excessive sliding of the slider 510 assembly, and significantly improving the stability and reliability of the device.

[0046] In some alternative embodiments, such as Figure 2 and Figure 5 As shown, the laser pointer 10 also includes a PCB assembly 700 (printed circuit board) located within the housing 100, and a tactile switch 710 is provided on the PCB assembly 700. Furthermore, the slider 510 has a first through hole 515 through which the trigger member 530 passes. When the protrusion 511 engages with the groove 310, pressing the trigger member 530 causes at least a portion of the trigger member 530 to pass through the first through hole 515 and trigger the tactile switch 710.

[0047] Based on the above settings, that is to say, the trigger 530 not only provides the user with an easy point of operation for applying force, but also enables precise interaction with the tactile switch 710 on the PCB assembly 700, thereby transforming the user's mechanical operation into a functional response and improving the overall functionality and intelligence level of the assembly.

[0048] In an embodiment where the laser pointer 10 is used as a laser pointer, the tactile switch 710 is used to control the laser to be turned on or off. That is, when the trigger 530 triggers the tactile switch 710, the laser is started and begins to work; when the trigger 530 does not trigger the tactile switch 710, the laser remains off and stops working.

[0049] Specifically, to ensure that the trigger 530 can accurately act on the tactile switch 710, the slider 510 is provided with a movable groove 513 extending in the opposite direction to the second direction 930, and the bottom wall of the movable groove 513 is provided with the first through hole 515. The trigger 530 slides in conjunction with the movable groove 513, and a protrusion 531 is provided on its lower side extending in the opposite direction to the second direction 930. The protrusion 531 is used to pass through the first through hole 515 to trigger the tactile switch 710.

[0050] In other words, when the trigger 530 is pressed, the trigger 530 slides along the movable groove 513, and the protrusion 531 extending from its lower side gradually approaches the first through hole 515. As the pressing force continues, the protrusion 531 is precisely aligned with and passes through the first through hole 515, and finally contacts the tactile switch 710 and triggers its function.

[0051] Furthermore, the sliding assembly 500 also includes an elastic element 550 sleeved on the protrusion 531, with both ends of the elastic element 550 abutting against the bottom wall of the movable groove 513 and the trigger 530, respectively, to reset the trigger 530. The elastic element 550 ensures that the trigger 530 quickly returns to its initial position after being removed from external force, preventing functional failure or jamming caused by the trigger 530 remaining in place. Simultaneously, the elastic element 550 effectively buffers external impact forces, reducing wear between components and thus extending the overall service life of the sliding assembly 500. Optionally, the elastic element 550 is made of silicone or a spring.

[0052] To prevent the trigger 530 from accidentally disengaging from the movable groove 513 under the action of the elastic element 550, a limiting groove 533 is recessed in the side wall of the trigger 530, extending along the second direction 930. The groove wall of the movable groove 513 is provided with a protrusion 517 that slides into the limiting groove 533. It can be understood that by the protrusion 517 abutting against the lower side wall of the limiting groove 533, the movement of the trigger 530 can be effectively limited.

[0053] Furthermore, to improve the sliding stability of the sliding component 500 within the housing, the laser pointer 10 also includes a fixing bracket 600 located between the PCB component 700 and the slider 510. The fixing bracket 600 is connected to the PCB component 700 and has a sliding groove 610 extending along the first direction 910. The slider 510 slides in conjunction with the sliding groove 610.

[0054] Understandably, on the one hand, the fixing bracket 600 provides reliable support for the slider 510 through its stable structure, effectively preventing the slider 510 from tilting or shifting during sliding; on the other hand, the sliding groove 610 on the fixing bracket 600 and the through hole 110 on the housing 100 cooperate to constrain the movement direction of the slider 510, ensuring that the slider 510 can only slide smoothly along the predetermined first direction 910, thereby significantly improving the overall stability and reliability of the sliding assembly 500. Optionally, the fixing bracket 600 and the PCB assembly 700 are connected by a snap-fit.

[0055] Furthermore, the bottom wall of the sliding groove 610 is provided with a second through hole 611, which is aligned with the tactile switch 710 and is used to align with the first through hole 515 when the protrusion 511 and the groove 310 are engaged, so that the protrusion 531 can pass through. That is to say, when the tactile switch 710 is triggered, the outer shell 100 and the cover 300 cannot rotate relative to each other due to the limiting and locking of the protrusion 511 and the groove 310.

[0056] Based on the above, when the laser pointer 10 provided by this utility model is applied to a laser pointer and the tactile switch 710 is used to turn on the laser, if the laser is in the on state, the outer shell 100 and the cover 300 cannot rotate relative to each other due to the limiting and locking effect of the protruding rib 511 and the groove 310. This design effectively prevents accidental opening of the cover during laser operation, thereby avoiding the risk of potential eye injury to the user or unrelated personnel, and significantly improving the safety and reliability of the product.

[0057] Taking the laser pointer 10 provided by this utility model as an example, its locking and unlocking principle is as follows:

[0058] To lock the cover 300 and the outer shell 100, after confirming that the threads of the cover 300 and the outer shell 100 are fully engaged, slide the trigger 530 and the slider 510 along the first direction 910 until the protrusion 511 on the slider 510 and the groove 310 of the cover 300 mutually limit each other. At this time, the cover 300 cannot rotate, thereby locking the cover 300 and the outer shell 100 and achieving the purpose of making it impossible to disassemble.

[0059] Additionally, it should be noted that when the cover 300 and the outer shell 100 are locked, the first through hole 515 of the slider 510 and the second through hole 611 of the fixing bracket 600 are connected. When the trigger 530 is pressed down, the protrusion 531 on the trigger 530 passes through the first through hole 515 and the second through hole 611 in sequence, abutting against the tactile switch 710, thus lighting the laser pointer. When the trigger 530 is released, under the action of the elastic element 550, the trigger 530 moves along the second direction 930, the protrusion 531 separates from the tactile switch 710, and the laser pointer is turned off.

[0060] To unlock the cover 300 and the outer shell 100, slide the trigger 530 and slider 510 in the opposite direction of the first direction 910. At this time, the first through hole 515 of the slider 510 and the second through hole 611 of the fixing bracket 600 are not connected, and the protrusion 531 and the tactile switch 710 are in an off-center state, preventing the laser pointer from being lit. At the same time, the protrusion 511 on the slider 510 disengages from the groove 310 of the cover 300, releasing its limiting effect. At this time, the cover 300 can rotate freely, and the cover 300 and the outer shell 100 can be opened by rotating the thread.

[0061] In summary, this utility model provides a laser pointer 10, which includes a housing 100, a cover 300, and a sliding component 500. The housing 100 has a through hole 110 extending along a first direction 910. The sliding component 500 slides within the through hole 110, allowing it to reciprocate along the first direction 910. The cover 300 is threadedly connected to the housing 100, forming a preliminary connection. The cover 300 also has a groove 310 communicating with the through hole 110 along the first direction 910. When the sliding component 500 is simultaneously within both the groove 310 and the through hole 110, the housing 100 and the cover 300 are locked, effectively limiting relative rotation between them. This effectively prevents children from easily opening the device, significantly improving the safety hazards caused by a simple opening mechanism.

[0062] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
