[0019] To facilitate understanding of the utility model's objectives and effects, the specific embodiments of the utility model are as follows, in conjunction with the accompanying drawings:

[0020] like Figures 1 to 4 As shown, a sealed battery compartment assembly designed to prevent detachment is provided. It includes a battery compartment 100 for accommodating a battery, with an L-shaped guide rail 200 at its opening edge. The guide rail 200 and the battery compartment 100 form a receiving space for a limiting post 330 (described in detail below). This receiving space includes an opening end 210 for the limiting post 330 to enter and a termination end 220 away from the opening end. When the limiting post 330 reaches the termination end 220, the rotating cover 300 is successfully engaged with the battery compartment 100. The guide rail 200 has a blocking protrusion 230 located near the termination end 220. During rotation, the rotating post 310 is confined between the termination end 220 and the blocking protrusion 230, thus limiting the rotation of the rotating post 310 and preventing the rotating cover 300 from rotating in the opposite direction and detaching from the battery compartment 100.

[0021] The rotating cover 300 is connected to the battery compartment 100. The rotating cover 300 includes a mounting post 310 and an operating plate 320 disposed on the top surface of the mounting post 310. The mounting post 310 is inserted into the battery compartment 100 to achieve the connection between the two. A limiting post 330 matching the accommodating space of the guide rail 200 is provided on the outer peripheral surface of the mounting post 310 near the operating plate 320. As the rotating cover 300 rotates, the limiting post 330 moves from the opening end 210 towards the termination end 220 until it passes the blocking protrusion 230 and reaches the termination end 220. The blocking protrusion 230 narrows the radial distance between the accommodating space formed by the guide rail 200 and the inner wall of the battery compartment 100, so that the limiting post 330 is fixed between the termination end 220 and the blocking protrusion 230. The top surface of the blocking protrusion 230 can be a flat surface or an arc surface.

[0022] In this embodiment, to improve the smoothness of the limiting post 330 passing over the blocking protrusion 230, transition slopes 231 are formed on both sides of the blocking protrusion 230. The transition slopes 231 can be symmetrically arranged about the axis of the blocking protrusion 230 or asymmetrically arranged. When the rotating cover 300 is in the initial rotation position, the guide rail 200 and the limiting post 330 are in clearance fit. When the rotating cover 300 rotates to the blocking protrusion 230 in the battery compartment 100, after passing the front transition slope 231, the guide rail 200 and the limiting post 330 change to an interference fit. At this time, the movement resistance increases, but after passing the front transition slope 231, it will reach the peak and move a certain distance in a plane. Then, it passes the rear transition slope 231 again and slides along it to the end 220. At this time, the guide rail 200 and the limiting post 330 are in clearance fit. Due to the setting of the blocking protrusion 230, when the rotating cover 300 is about to be rotated and assembled into place, the resistance increases. After increasing the force to rotate and assemble, the rotating cover 300 will slide along the transition slope 231 of the blocking protrusion 230 to the final end 220. At this time, the rotating cover 300 has been assembled into place and will not move backward.

[0023] In this embodiment, the outer peripheral surface of the mounting post 310 is provided with a sealing groove 400 for mounting the sealing ring 500, and the sealing ring 500 is embedded in the sealing groove 400; the sealing ring 500 is made of silicone or rubber and other elastic materials; the sealing groove 400 is located below the limiting post 330. Preferably, there are two sealing grooves 400, coaxially arranged along the axis of the limiting post 330, which provides double sealing protection. The double sealing ring structure ensures that water will not enter the battery compartment 100 and affect battery performance.

[0024] In this embodiment, the top surface of the operation panel 320 is provided with an operation opening for securing disassembly and assembly tools. Guiding marks are also provided on the surface of the operation panel 320 to indicate the opening and closing directions. Using a hex wrench, rotate the rotating cover 100 in the direction indicated by the arrow. When it is almost fully rotated, you will feel increased resistance. Continue rotating until it stops rotating; at this point, the product assembly is complete. To replace the battery, insert a hex wrench into the operation opening and rotate the battery cover counterclockwise in the direction indicated by the arrow.

[0025] The above description is merely a preferred embodiment of this utility model and is not intended to limit this utility model in any form or substance. It should be noted that those skilled in the art can make several improvements and additions without departing from this utility model, and these improvements and additions should also be considered within the protection scope of this utility model. Any modifications, alterations, and equivalent changes made by those skilled in the art based on the above-disclosed technical content without departing from the spirit and scope of this utility model are equivalent embodiments of this utility model. Furthermore, any modifications, alterations, and evolutions made to the above embodiments based on the essential technology of this utility model still fall within the scope of the technical solution of this utility model.
