[0013] Further, the inner wall of the lower shell rotating shaft groove is provided with at least one pair of side wall blocks, and the included angle of the side wall blocks determines the fixed opening angle of the die-cast shell upper cover.

[0014] Further, the included angle of the side wall blocks is a customizable angle of 15°-90°, and the fixed opening angle of the die-cast shell upper cover is consistent with the included angle of the side wall blocks.

[0015] Further, the matching surface of the upper cover rotating shaft protrusion and the lower shell rotating shaft groove is provided with a guide slope for guiding the upper cover rotating shaft protrusion to quickly penetrate into or out of the lower shell rotating shaft groove.

[0016] Further, the die-cast shell upper cover, the upper cover rotating shaft protrusion and the die-cast shell lower bottom are integrally formed by a die-casting process, and the lower shell rotating shaft groove is a prefabricated groove structure of the die-cast shell lower bottom.

[0029] Example 1: Die-cast integrated shaft structure for industrial control boxes

[0030] like Figures 1-3 As shown, the die-cast integrated rotating shaft structure that can fix the opening angle includes:

[0031] I. Structural Composition

[0032] Die-cast outer shell cover 1:

[0033] Material: Die-cast aluminum alloy (such as ADC12), with anodized surface for corrosion resistance.

[0034] Structure: The top is a rectangular box cover, and the side is provided with two integrally formed cylindrical top cover pivot protrusions 2 (including shaft 21 and protrusion 22, the protrusion 22 is located at the end of the shaft, so that the shaft 21 can cooperate with the round hole part 31 of the lower shell pivot groove 3 to realize the rotation of the die-cast outer shell top cover 1). The shaft 21 has a diameter of Φ8mm and a length of 15mm, and the protrusion 22 has a 30° guide chamfer.

[0035] Die-cast shell bottom 4:

[0036] Material: Same as the die-cast outer shell cover, made of ADC12 aluminum alloy die-casting.

[0037] Structure: the side is provided with two symmetrically arranged lower shell rotating shaft grooves 3, each groove is a circular hole part 31 and a groove part 32, the diameter of the circular hole part 31 is Φ8.2mm, and the depth is 10mm; one pair of side wall blocks 5 is arranged on one side of the inner wall of the groove, the included angle of the two side wall blocks 5 is 45° (which can be other angles, which is not limited here), and the height of the side wall block 5 is 5mm, which is used to limit the opening angle.

[0038] II. Workflow

[0039] 1. Installation process

[0040] Angle alignment: adjust the opening angle of the die-cast shell upper cover 1 to be consistent with the axial angle of the lower shell rotating shaft groove 3 (i.e. 0° closed state).

[0041] Pulling connection: align the upper cover rotating shaft protrusion 2 with the lower shell rotating shaft groove 3, push it in the axial direction, and guide the chamfer to guide the protrusion 22 to quickly insert into the groove part 32, until the bottom of the protrusion 22 contacts the bottom surface of the groove (installation is completed).

[0042] 2. Cover opening and fixing process

[0043] Rotary opening: manually lift the die-cast shell upper cover 1 upward, and the upper cover rotating shaft protrusion 2 rotates around the center of the groove.

[0044] Angle limiting: when the opening angle reaches 45°, the side wall of the upper cover rotating shaft protrusion 2 abuts against the side wall block 5 of the lower shell rotating shaft groove 3, the protrusion 22 cannot continue to rotate, so that the upper cover is fixed to remain in the 45° opening state (satisfying the maintenance requirement in a narrow space, and the 45° here is only an example), as shown in Figure 3 The side wall block 5 of the protrusion 22 is blocked.

[0045] 3. Disassembly process

[0046] Angle resetting: gently press the upper cover downward to restore it to the 0° closed state, so that the protrusion 22 is separated from the side wall block 5, as shown in Figure 2 The state shown.

[0047] Pulling separation: pull out the upper cover rotating shaft protrusion 2 in the axial direction until it is completely separated from the lower shell rotating shaft groove 3, and the disassembly is completed, as shown in Figure 1 The state shown.

[0048] III. Key technical feature implementation

[0049] 1) One-piece molding process:

[0050] The upper cover rotating shaft protrusion 2 and the die-cast shell upper cover 1 are formed by die casting through the same mold, without welding or assembly process, reducing the number of parts.

[0051] The lower shell rotating shaft groove 3 is a prefabricated structure directly formed during die casting, without subsequent drilling processing, thereby reducing cost.

[0052] 2) Angle customization design:

[0053] In this example, the included angle of the stop block is 45°, which is suitable for internal maintenance of a control box with a depth of 200 mm (narrow space scenario); if a larger angle is required, the included angle of the stop block can be adjusted to 60° or 90°.

[0054] 3) Material and reliability:

[0055] The aluminum alloy material has low density, high strength, and better corrosion resistance than copper or stainless steel, and is suitable for harsh conditions such as humidity and dust in industrial environments.

[0056] Four, application scenarios

[0057] Suitable equipment: industrial automation control box, outdoor power equipment shell, small instrument box, etc.

[0058] Core advantage: in a narrow space with a depth of ≤300 mm, by fixing the opening angle at 45°, the circuit board and wiring terminal inside the box can be directly maintained without completely opening the upper cover, saving operation space and improving efficiency.
