Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), such directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0026] The utility model provides a ring network cabinet which can be adapted to batteries of different specifications.

[0027] In this embodiment, referring to Figure 1-4 The ring main unit that can adapt to batteries of different specifications includes a ring main unit cabinet 1 and a battery mounting rack 15 arranged on the bottom wall of the cabinet;

[0028] The battery mounting rack includes two clamping plate assemblies arranged opposite each other, and a mounting area 2 for mounting batteries is formed between the clamping plate assemblies. The clamping plate assembly includes an "L"-shaped bottom plate 3, an "L"-shaped adjustment plate 4, and an elastic member 5. The horizontal plate of the "L"-shaped bottom plate 3 is provided with a first long groove 7 for the screw 6 on the bottom wall of the cabinet to pass through, so that the "L"-shaped bottom plate can be adjusted along the first long groove. After adjustment, a nut is fixed on the screw.

[0029] A telescopic groove 8 is provided on the vertical plate of the "L"-shaped base plate, and the vertical plate of the "L"-shaped adjustment plate slides in cooperation with the above-mentioned telescopic groove, and corresponding second long grooves 9 are provided on the vertical plate of the "L"-shaped adjustment plate and the vertical plate of the "L"-shaped base plate, and the elastic member has an elastic pulling force for pulling the "L"-shaped adjustment plate back into the telescopic groove.

[0030] In the above technical solution, by providing an adjustable battery mounting bracket, this application can accommodate batteries of various widths and heights. This design not only improves the compatibility of the ring main unit with various battery products on the market, but also simplifies the battery replacement process and reduces maintenance costs. The design of the clamping plate assembly ensures that the battery is firmly fixed in the installation area, ensuring battery safety and stability.

[0031] During use, adjust the L-shaped base plate according to battery size by moving it along the first slot to adjust the width, front, back, left, and right. Similarly, adjust the height of the L-shaped adjustment plate by adjusting the depth of its extension into the expansion slot. After adjusting the position, secure the L-shaped base plate and adjustment plate with bolts inserted through the second slot. Install nuts on the screws to secure the L-shaped base plate to the cabinet bottom wall.

[0032] In addition, due to the setting of the elastic part, after placing the battery and adjusting the front, back, left and right widths, the elastic part can be used to pre-tighten and fix the battery using the horizontal plate of the "L"-shaped adjustment plate, which is convenient for subsequent fixation.

[0033] Specifically, the elastic member 5 is a spring, one end of which is connected to the bottom wall of the telescopic slot, and the other end of which is connected to the vertical plate of the L"-shaped adjustment plate.

[0034] Using a spring as the elastic member 5 can provide a constant elastic tension between the “L”-shaped adjustment plate and the telescopic slot, thereby improving the stability of battery installation.

[0035] Specifically, an elastic pad 10 is provided on the lower end surface of the horizontal plate of the L"-shaped adjustment plate.

[0036] Elastic pads are installed on the lower end of the horizontal plate of the "L"-shaped adjustment plate to provide additional cushioning protection during battery installation, reducing damage caused by hard contact. The elastic pads also increase friction between the battery and the mounting bracket, further strengthening the battery's securement and preventing displacement during transportation or use.

[0037] Specifically, it also includes a cover plate 11, a fixing stud 12 is provided on the upper end surface of the horizontal plate of the L"-shaped adjustment plate, and a mounting hole 13 for the fixing stud to pass through is provided on the cover plate.

[0038] The plate not only increases the enclosure of the entire mounting frame, preventing dust and other impurities from entering, but also allows the cover to be securely mounted on the "L"-shaped adjustment plate via fixing studs, forming a complete protective structure. This helps improve battery safety and allows other components to be installed on the cover.

[0039] Specifically, the elastic members are arranged at equal intervals along the length direction of the telescopic slot.

[0040] Arranging multiple elastic parts (such as springs) at equal intervals along the length of the expansion slot can evenly distribute the pressure applied to the "L"-shaped adjustment plate, enhance stability and reliability, and reduce the potential failure risk caused by local stress concentration.

[0041] Specifically, a spacer 14 is provided on the bottom wall of the installation area.

[0042] Setting a spacer on the bottom wall of the installation area can provide an elevated installation position for the battery, which is conducive to heat dissipation and prevents water accumulation at the bottom. At the same time, a finger gap is left between the bottom of the battery and the bottom wall of the cabinet to facilitate battery removal.

[0043] Specifically, the thickness of the raising sheet is 1-2 cm.

[0044] The thickness of the spacer is set at 1-2 cm. This range effectively elevates the battery position to facilitate heat dissipation and waterproofing, while not excessively increasing the overall height of the structure, ensuring efficient use of the internal space of the ring main unit. This design balances functionality and compactness, improving the overall performance of the ring main unit.

[0045] Technical personnel please note: Although the utility model has been described according to the above specific implementation methods, the concept of the utility model is not limited to this utility model. Any modification using the concept of the utility model will be included in the scope of protection of this patent right.
