Description

Technical Field

[0001] The present invention mainly relates to the technical field of laser pointers, and particularly relates to a remote control laser pointer that is convenient for charging. Background Art

[0002] As a commonly used presentation tool, laser pointers are widely used in teaching, lectures, conferences and other scenarios. Traditional laser pointers usually use disposable button batteries for power supply, such as models like CR2032. This power supply method has the inconvenience of replacing batteries. Since the laser pointer is relatively small in size, the battery compartment is usually designed to be relatively compact. Users need to use tools or struggle to disassemble and assemble when replacing the battery, which is cumbersome to operate and affects the user experience. Moreover, it cannot be charged and has poor environmental friendliness: once the disposable battery runs out of power, it needs to be discarded and replaced with a new battery, which not only increases the usage cost but also causes waste of resources and environmental pollution.

[0003] Although there are some laser pointers on the market that support USB charging, there is still a problem that the structure is complex, resulting in a relatively large weight of the laser pointer. Therefore, there is an urgent need to design a remote control laser pointer with a simple structure, convenient charging, environmental friendliness and durability to solve the above technical problems.

[0004] It should be noted that the above content belongs to the technical cognition scope of the inventor. Due to the vast and extremely complex technical content in this field, the above content of this application does not necessarily constitute the prior art. Summary of the Invention

[0027] The charging port 5 adopts one of USB-C, Lightning, and Micro USB. In this embodiment, a relatively common charging port 5 is adopted to improve the applicability of the device.

[0028] The laser pointer main body 1 includes a laser emission tube 11. The bottom of the laser emission tube 11 is connected to a charging battery bin tube 12. The bottom of the charging battery bin tube 12 is connected to the magnetic charging connector 2. A switch button 13 is provided on the side of the laser emission tube 11. The laser pointer main body 1 adopts an integrated cylindrical design and is mainly composed of three parts: a laser emission tube 11, a charging battery bin tube 12, and a magnetic charging connector 2. The components are connected by threads or buckles to ensure a stable structure. A switch button 13 is provided on the side of the laser emission tube 11, which is made of silicone material and has an anti-misoperation design. The user can control the laser on and off by pressing the switch short, and can switch the laser to blink by pressing and holding. The charging battery bin tube 12 is connected to the bottom of the laser emission tube 11 and internally encapsulates a rechargeable lithium battery with a capacity of 300 mAh to 500 mAh, supporting a standard voltage output of 3.7V. The magnetic charging connector 2 is automatically aligned with an external charging cable through magnetic adsorption during charging, avoiding plugging and unplugging wear.

[0029] Concave friction grooves 14 are annularly arranged on the outer surface of the charging battery bin tube 12. In this embodiment, the setting of the concave friction grooves 14 can increase the friction when the user holds the charging battery bin tube 12, facilitating the operation of the laser pointer by the operator.

[0030] A concave card slot 15 is provided on the top of the laser emitting tube 11, and the concave card slot 15 is magnetically connected to the sliding pen tip 16.

The rotating roller 32 is symmetrically connected to a support plate 33. The bottom of the support plate 33 is slidably connected to a telescopic column 34. The bottom of the telescopic column 34 is connected to a support frame 35. A spring 36 is provided between the support frame 35 and the support plate 33. In order to improve the stability of the charging compartment base 3, when the laser pen body 1 is charging, the support frames 35 on both sides are bent toward both sides. When the support frames 35 are bent outward, the support frames 35 extend outward under the action of the spring 36 to form a supporting structure.

[0035] The outer side of the support plate 33 is connected to the limiting card plate 331, and the bottom of the support frame 35 is symmetrically connected to the locking ball 332. The corresponding position of the square groove 31 is provided with a locking groove 333 to match the locking ball 332. The limiting card plate 331 can limit the rotation angle of the support frame 35, which is convenient for the support frame 35 to perform supporting operations. When the support frame needs to be retracted, the locking ball 332 at the bottom of the support frame 35 can be inserted into the locking groove 333.
