[0033] To make the technical solutions and effects of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0034] Please see Figure 1 This utility model aims to provide a WIFI stick with convenient assembly and disassembly and multi-functional integration, including a WIFI stick body 100. The WIFI stick body 100 mainly includes a shell 110, a top cover 120, and a fixing rotating nut 130. The following is a main description of each structure.

[0035] Please see Figure 2 The outer casing 110 has a receiving chamber, and a PCB board 111 is internally positioned and fixed within the receiving chamber. Specifically, the receiving chamber has a fixing groove adapted to fit the PCB board 111 to engage and fix the PCB board 111. In this embodiment, a rectangular fixing groove is machined at the bottom of the receiving chamber of the outer casing 110, and three sets of symmetrically distributed protruding limiting blocks are provided on its sidewalls, forming an interference fit with the grooves on the edges of the PCB board 111. When the PCB board is inserted into the receiving chamber, the limiting blocks press against the sidewalls of the grooves on the PCB board 111, generating a radial preload, which serves to fix and limit the PCB board 111. Figure 3As shown, the PCB board 111 integrates an LED light guide column 111a and a USB function module 111b. The LED light guide column 111a extends to the light-transmitting area of ​​the housing 110, guiding the LED light from the PCB board 111 to the outside for visual display, providing a clear indication of the device's operating status. The USB function module 111b includes a Type-C interface and / or a USB-A interface. The LED light guide column 111a, in conjunction with the LED light, enables visualization of the operating status; the USB function module 111b expands the device's connectivity and application scenarios, such as connecting external storage devices and charging, enhancing the practicality and added value of the WiFi stick and meeting diverse user needs.

[0036] Please see Figure 5-7 The upper cover 120 is fixedly and sealed to the open end of the outer shell 110, and snaps into the PCB board 111. Specifically, the upper cover 120 and the open end of the outer shell 110 are fixedly connected by fasteners, and a rubber plug 125 is provided at the connection between the upper cover 120 and the outer shell 110 to seal the mounting holes and gaps of the fasteners. The fasteners can be screws. In a further embodiment, the upper cover 120 is snapped into and fixed to the PCB board 111 by a U-shaped slot 121 with opposing openings. The synergistic effect of the fixing slot and the U-shaped slot 121 effectively prevents the PCB board 111 from loosening or shifting in a vibration environment. In a further embodiment, a waterproof sealing ring 124 is provided on the contact surface between the upper cover 120 and the open end of the outer shell 110. Preferably, the waterproof sealing ring 124 meets the IP66 protection level requirements, and the waterproof sealing ring 124 covers the entire mating surface between the upper cover 120 and the outer shell 110. The combined effect of the waterproof sealing ring 124 and the rubber stopper 125 effectively prevents external dust and moisture from intruding and affecting the performance of the equipment.

[0037] Please see Figure 4 The fixed rotating nut 130 is fixedly connected at both ends to the upper cover 120 and the external device, respectively, wherein the fixed rotating nut 130 and the external device are detachably connected. In this embodiment, the inner wall of the end of the fixed rotating nut 130 away from the external device has a plurality of elastic claws 131 distributed circumferentially; the contact surface between the upper cover 120 and the fixed rotating nut 130 is provided with an annular groove 122, and a guide slope 123 is provided between the annular groove 122 and the end of the upper cover 120 to guide the elastic claws 131 to engage with the annular groove 122. Specifically, during assembly, the fixed rotating nut 130 is pressed axially, and the elastic claws 131 are compressed and contracted by oblique compression. After the elastic claws 131 slide into the annular groove 122, they elastically reset and lock, so that the fixed rotating nut 130 can rotate freely relative to the upper cover 120 but is axially fixed. In a further embodiment, the contact surface between the fixed rotating nut 130 and the external device is provided with a threaded structure, so that the fixed rotating nut 130 and the external device are rotatably and fixedly connected. By rotating clockwise and counterclockwise, the fixed rotating nut 130 and the external device can be quickly disassembled and assembled.

[0038] During installation, hold the WIFI stick body 100 and rotate the fixing nut 130 to make its internal thread structure match the thread of the external device (such as the adapter interface of the router, industrial control computer, etc.) to complete the quick connection.

[0039] During disassembly, simply rotate the retaining nut 130 in the opposite direction to disconnect it from the external device, allowing you to easily remove the WIFI stick body 100. If you need to maintain the internal components of the WIFI stick body 100, remove the retaining screws of the top cover 120, and remove the rubber plug 125 and waterproof sealing ring 124 to inspect or replace the PCB board 111.

[0040] In working mode, after the WiFi stick body 100 is connected to the power supply circuit, the USB function module 111b on the PCB board 111 is activated, and the LED light guide column 111a emits light, which is displayed through the corresponding light-transmitting area of ​​the outer shell 110, intuitively showing the device's working status, such as signal strength and power-on status. At the same time, the USB function module 111b can be connected to external USB flash drives and mobile hard drives to achieve data sharing, or to charge mobile phones and smart wearable devices, expanding the usage scenarios.

[0041] Compared with existing WiFi sticks, the WiFi stick provided by this utility model has the following advantages:

[0042] Easy to install and remove: The WIFI stick can be installed and removed from external devices by rotating the fixing nut 130 in both directions. Compared with the traditional complicated connection method, it saves a lot of operation time and improves the convenience of use, especially in the case of equipment maintenance and replacement.

[0043] Structural stability: The fixing groove in the housing 110 limits and fixes the PCB board 111, and the screw connection between the top cover 120 and the housing 110, plus the waterproof sealing ring 124 and rubber plug 125 seal, ensure the stability and sealing of the overall structure of the WIFI stick, which not only prevents the internal PCB board 111 from loosening or shifting, but also isolates external dust and moisture from intrusion.

[0044] Functional integration: The PCB board 111 integrates LED light guide column 111a and USB function module 111b, which enhances the practicality and added value of the WIFI stick and meets the diverse needs of users.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
