[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1 to 4 This utility model provides an intelligent power switch cabinet with convenient temperature sensor assembly and disassembly. It includes a cabinet body 1, with multiple slide rails 2 connected to the inner side of the cabinet body 1. The number of slide rails 2 and sensor bodies 3 is selected according to the size of the cabinet body 1 to facilitate temperature monitoring of different areas inside the cabinet body 1. Each slide rail 2 is connected to a movable sliding block 6, which slidably connects to the slide rail 2, improving the stability of the sliding block 6's reciprocating movement. A fixed interface 9 is connected to the side of the sliding block 6, and a detachable sensor body 3 is connected to the fixed interface 9. The fixed interface 9 also connects to a positioning mechanism for positioning the sensor body 3. The positioning mechanism includes a movable sleeve 7, a spring 5, and multiple positioning balls 13. The movable sleeve 7 is movably connected to the fixed interface 9, and the spring 5 drives the movable sleeve 7 to move closer to the sensor body 3. The positioning balls 13 are connected to the fixed interface 9 and match the ball grooves 16 provided on the sensor body 3. Typically, four positioning balls 13 are provided, with adjacent balls having an included angle of 90°.

[0021] When installing the sensor body 3, the fixed interface 9 can be driven to slide along the length of the slide rail 2 to change the installation position of the sensor body 3. It can be flexibly adjusted according to actual installation needs and has strong applicability.

[0022] When the sensor body 3 is connected to the fixed interface 9, the movable sleeve 7 is released directly. The compressed spring 5 drives the movable sleeve 7 to move, so that the inner side of the movable sleeve 7 presses against the positioning ball 13. The positioning ball 13 is connected to the ball groove 16, which realizes the quick installation and fixation of the sensor body 3 and improves the stability of the connection between the sensor body 3 and the fixed interface 9.

[0023] When the sensor body 3 needs to be disassembled for maintenance, press the movable sleeve 7 again, the spring 5 is compressed, the movable sleeve 7 separates from the four positioning balls 13, thereby loosening the sensor body 3 and facilitating the disassembly and maintenance of the sensor body 3.

[0024] The positioning mechanism also includes a spring groove and multiple movable cavities 12. The spring groove is located inside the movable sleeve 7, and the movable cavities 12 are located at the fixed interface 9. The positioning ball 13 is connected to the movable cavity 12. The positioning ball 13 can move within the movable cavity 12, but cannot be removed from the movable cavity 12, thus limiting the positioning ball 13.

[0025] One end of spring 5 is connected to the spring groove, and the other end is connected to the sliding block 6.

[0026] A connecting groove 10 is provided inside the fixed interface 9. The sensor body 3 is connected to the connecting groove 10, and the cross-section of the connecting groove 10 is circular.

[0027] Two connecting plates 4 are connected to the outer side of the movable sleeve 7. The end of the connecting plate 4 is connected to a positioning head 11, which is connected to the slide rail 2. When the movable sleeve 7 is released, the compressed spring 5 can drive the movable sleeve 7 to move closer to the sensor body 3, and simultaneously drive the two connecting plates 4 to move, so that the positioning head 11 is connected to the corresponding limiting groove 8, thereby limiting the fixed interface 9 and improving the stability of the connection between the sensor body 3 and the slide rail 2.

[0028] The movable sleeve 7 is slidably connected to the outside of the fixed interface 9, so that the movable sleeve 7 can move back and forth steadily along the length of the fixed interface 9.

[0029] The inner side of the movable sleeve 7 is connected to a guide block, which is slidably connected to a guide groove located on the outer side of the fixed interface 9. This guide block provides guidance for the movable sleeve 7, meaning that the movable sleeve 7 moves along the length of the fixed interface 9 and cannot rotate.

[0030] The slide rail 2 has multiple limiting grooves 8 on its side, and the positioning head 11 matches the limiting grooves 8.

[0031] The fixed interface 9 has multiple positioning slots 14 at its end, and the sensor body 3 is connected to multiple positioning protrusions 15, which match the positioning slots 14. There are four positioning slots 14, and four corresponding positioning protrusions 15. The positioning slots 14 are aligned with the movable cavity 12. During sensor body 3 installation, the positioning protrusions 15 are connected to the positioning slots 14 to initially limit the position of the sensor body 3. At this time, the ball groove 16 is aligned with the positioning ball 13, facilitating subsequent docking.

[0032] The end of the movable sleeve 7 is provided with a guide surface 17, which is a smooth surface. When the movable sleeve 7 moves, the guide surface 17 slides relative to the positioning ball 13, which can reduce the contact friction and drive the positioning ball 13 to move towards the corresponding ball groove 16 until the inner side of the movable sleeve 7 is connected to the positioning ball 13. Then the positioning ball 13 is connected to the ball groove 16, thereby locking and fixing the sensor body 3.

[0033] Working Principle: The fixed interface 9 slides on the slide rail 2, changing the installation position of the sensor body 3, which can be flexibly adjusted according to actual installation requirements. Pressing the movable sleeve 7 moves it towards the sliding block 6, and the spring 5 is gradually compressed, separating the movable sleeve 7 from the positioning ball 13. Then, the sensor body 3 is connected to the connecting groove 10 of the fixed interface 9, and the positioning protrusion 15 is connected to the positioning groove 14, achieving initial positioning of the sensor body 3. Releasing the movable sleeve 7 again causes the compressed spring 5 to drive the movable sleeve 7 to move, so that the inner side of the movable sleeve 7 is connected to the four positioning balls 13, and the positioning balls 13 are connected to the ball groove 16, achieving quick installation and fixation of the sensor body 3, improving the stability of the connection between the sensor body 3 and the fixed interface 9, and increasing installation efficiency. At the same time, the movement of the movable sleeve 7 can drive the two connecting plates 4 to move synchronously, so that the positioning head 11 is connected to the corresponding limiting groove 8, achieving positioning of the fixed interface 9, improving the stability of the connection between the sensor body 3 and the slide rail 2, making the operation flexible and convenient, and highly practical.

[0034] 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.
