[0018] Example 1:

[0019] Please see Figures 1-4This utility model discloses a power supply module for a display rack with overload protection, comprising a display rack assembly 1, an overload protection assembly 2, and a detection assembly 3. The rear end of the display rack assembly 1 is fixedly connected to the overload protection assembly 2, and the interior of the overload protection assembly 2 is fixedly connected to the detection assembly 3. The display rack assembly 1 also includes a display rack 11, the rear end of which is fixedly connected to the overload protection assembly 2; a slide groove 12 located inside the display rack 11; a power socket 13 fixedly connected to the rear end of the display rack 11; a shelf 14 slidably connected to the display rack 11 via the slide groove 12; a connector 15 fixedly connected to the rear end of the shelf 14; and a lighting lamp 16 fixedly connected to the shelf 14. The lighting lamp 16 provides independent and directional lighting for each item displayed on each shelf. The light moves with the shelf 14, always illuminating the exhibits at the optimal angle to enhance the display effect. The rear end of the connector 15 is slidably connected to the power socket 13, which is located at the rear end of the slide groove 12.

[0020] The overload protection component 2 consists of an overload protection frame 21 fixedly connected to the rear end of the display rack 11, an upper dustproof net 22 fixedly connected to the upper side of the rear end of the overload protection frame 21, a temperature sensor 23 fixedly connected to the lower end of the overload protection frame 21, and a temperature sensor 23 fixedly connected to the lower end of the overload protection frame 21. The temperature sensor 23 is set to monitor the temperature around the protector in real time. It can issue an alarm or trigger protection in advance when abnormal temperature rise occurs due to poor contact, slow overload, etc., but the current protection threshold is not reached, thus preventing problems before they occur. The side dustproof net 24 is fixedly connected to the lower side of the left and right ends of the overload protection frame 21, the overload protector 25 is fixedly connected to the lower end of the overload protection frame 21, and the wire 26 is fixedly connected to the upper end of the overload protector 25.

[0021] This utility model provides an improved power supply module for a display rack with overload protection, the working principle of which is as follows; First, when using this device, place it in the work area and then connect it to an external power source to provide the necessary electrical energy for its operation. Secondly, when this device is needed, the shelf 14 can be inserted into the display rack 11, and the connector 15 can be connected to the power socket 13 to supply power to the lighting lamp 16, so that the lighting lamp 16 can be turned on to illuminate the displayed items. Then, the temperature sensor 23 can be activated through the display controller 31 to monitor the temperature around the protector in real time. It can issue an alarm or trigger protection in advance if abnormal temperature rise occurs due to poor contact, slow overload, etc., but before the current protection threshold is reached, thus preventing problems before they occur. The overload protector 25 can quickly cut off the circuit when the current exceeds the predetermined safety value, effectively preventing the risk of wire overheating, equipment damage, or even fire caused by short circuits and overloads. Furthermore, the upper dustproof net 22 and the side dustproof net 24 ensure air circulation inside and outside the rack to facilitate heat dissipation, while effectively blocking most of the dust and foreign objects from entering, preventing poor heat dissipation of components, reduced insulation performance, or contact failure caused by dust accumulation, thus improving the long-term reliability of the system.

[0022] Example 2:

[0023] Please see Figures 1-4 Compared to Embodiment 1, this utility model provides a power supply module for a display rack with overload protection. This embodiment further includes: a detection component 3; a display controller 31 fixedly connected to the upper end of the display rack 11; an indicator light 32 fixedly connected to the upper end of the display controller 31; a wireless transceiver 33 fixedly connected to the rear end of the display controller 31; a fan 34 fixedly connected to the upper interior of the overload protection frame 21; a flame detector 35 fixedly connected to the upper interior of the overload protection frame 21; and a current transformer 36 fixedly connected to the lower interior of the overload protection frame 21. The fan 34 is positioned at the front end of the upper dustproof net 22. The fan 34 acts as an active cooling device, automatically activating when the internal temperature is detected to be too high, forcibly expelling hot air and drawing in cold air, significantly enhancing the heat dissipation capacity of the entire protection module, ensuring that components operate at a suitable temperature, extending service life and improving stability. An electric wire 26 is installed in the annular groove at the upper end of the current transformer 36.

[0024] In this embodiment: When cooling is required, the fan 34 can be started via the display controller 31 when the temperature sensor 23 detects a high temperature inside the overload protection frame 21. After the fan 34 starts, hot air is forcibly expelled and cold air is drawn in, significantly enhancing the heat dissipation capacity of the entire protection module. This ensures that components operate at a suitable temperature, extending their service life and improving stability. Furthermore, the current transformer 36 accurately detects the current in the circuit non-contactly and sends the signal to the display controller 31, providing the basis for intelligent overload judgment and monitoring. It has low power consumption and is safe. Simultaneously, it can control the flame detector 35 to activate in extreme situations such as the initial stage of an electrical fire. When an open flame occurs, the system can detect the flame signal very early and trigger the highest level alarm and power outage, buying valuable time for firefighting and preventing the disaster from escalating. The indicator lights 32 can display the working status, current value, or fault codes such as overload and overheating in real time. The indicator lights 32 provide intuitive and eye-catching status prompts, such as green light for normal and red light for fault, so that users can quickly understand the status of the components. The display controller 31 can also wirelessly transmit operating data, fault alarms, and other information to the monitoring center or the user's mobile device via the wireless signal transceiver 33, which is convenient for centralized management, remote fault diagnosis, and historical data recording, greatly improving the manageability and modernization level of the equipment.

[0025] This utility model provides an improved power supply module for a display rack with overload protection. By incorporating multiple safety components such as overload protection, current detection, temperature monitoring, and flame detection, and adopting a sliding power supply structure for the shelf 14, it effectively solves the problems of poor flexibility and insufficient safety in the circuit system of traditional display racks 11. Through integrated design, it realizes intelligent power management, early warning of faults, and remote alarm, significantly improving the safety and maintainability of the equipment, while maintaining the flexible adjustment capability of the display layout.
