Detailed Implementation

[0015] The embodiments of this utility model will be described below with reference to the accompanying drawings and related examples. The embodiments of this utility model are not limited to the following examples, and this utility model relates to relevant necessary components in this technical field, which should be regarded as well-known technology in this technical field and can be known and mastered by those skilled in this technical field.

[0016] like Figures 1 to 3 As shown, this low-voltage cabinet with adjustable outgoing switch position includes a housing 1, several horizontal beams 2, a foundation mounting plate 3, a vertical support plate 4, a switch mounting plate 5, and a molded case switch 6.

[0017] The housing 1 is typically made of metal, forming the outer shell structure of the low-voltage switchgear. Several horizontal beams 2 are fixed to the inner walls on both sides of the housing 1 to support the internal components.

[0018] The horizontal beams 2 are horizontally fixed to both sides of the housing 1, and each horizontal beam 2 has several first connecting holes 21. These first connecting holes 21 are usually threaded holes or through holes, used for connecting to the base mounting plate 3.

[0019] The base mounting plate 3 has a first elongated hole 31 on its side, which is connected to the first connecting hole 21 of the horizontal beam 2 by bolts or other fasteners, thus achieving a detachable connection. The front of the base mounting plate 3 has multiple rows of second elongated holes 32, which are arranged vertically to allow the vertical support plate 4 to be adjusted in the height direction.

[0020] The vertical support plate 4 has a second connecting hole 41 on its side, which is connected to the second elongated hole 32 of the base mounting plate 3 by bolts to achieve a detachable connection. The wide side of the vertical support plate 4 (i.e. the edge connected to the switch mounting plate 5) has a third elongated hole 42. These elongated holes extend horizontally, allowing the switch mounting plate 5 to be adjusted in the depth direction.

[0021] The switch mounting plate 5 has a third connecting hole 51 on its side, which is connected to the third elongated hole 42 of the vertical support plate 4 by bolts, achieving a detachable connection. The front of the switch mounting plate 5 has a fourth elongated hole 52, through which the molded case switch 6 is fixedly connected to the switch mounting plate 5 by bolts passing through the fourth elongated hole 52. The fourth elongated hole 52 allows the molded case switch 6 to move horizontally or vertically on the switch mounting plate 5, enabling fine adjustment.

[0022] As shown in the diagram, during assembly, first, the horizontal beam 2 is fixed to the housing 1. Then, the base mounting plate 3 is installed, and its horizontal position is adjusted using the first elongated hole 31 and the first connecting hole 21. Next, the vertical support plate 4 is installed on the base mounting plate 3 using the second connecting hole 41 and the second elongated hole 32, and its height is adjusted. Then, the switch mounting plate 5 is installed on the vertical support plate 4 using the third connecting hole 51 and the third elongated hole 42, and its depth is adjusted. Finally, the molded case switch 6 is fixed to the fourth elongated hole 52 of the switch mounting plate 5, completing the position adjustment. This structure allows the molded case switch 6 to be flexibly adjusted in three dimensions (horizontal, vertical, and depth) to meet different wiring requirements.

[0023] To facilitate the installation and position adjustment of the horizontal beam 2 on the housing 1, several vertically arranged first guide rails 11 are provided on the inner walls of both sides of the housing 1. The first guide rails 11 are typically metal guide grooves, fixed to the inner wall of the housing 1. First sliders 22, which cooperate with the first guide rails 11, are provided at both ends of the horizontal beam 2. The first sliders 22 can be slider structures, allowing the horizontal beam 2 to be slidably installed within the first guide rails 11 via the first sliders 22. In this way, the horizontal beam 2 can move vertically to adjust its height.

[0024] To fix the position of the horizontal beam 2, a fixing bracket 24 is fixed below the first slider 22. A bolt 25 is fixed to the fixing bracket 24 near the first guide rail 11, with the end of the bolt 25 close to the first guide rail 11 and a torque handle 26 at the head of the bolt 25. When the horizontal beam 2 moves to the desired height, rotating the torque handle 26 causes the end of the bolt 25 to press against the first guide rail 11, thereby locking the horizontal beam 2 in its current position. This design allows for quick adjustment and fixing of the horizontal beam 2, improving installation efficiency.

[0025] To further simplify the connection and adjustment between the base mounting plate 3 and the horizontal beam 2, a second guide rail 23 is detachably mounted on the horizontal beam 2. The second guide rail 23 is fixed to the top or side surface of the horizontal beam 2 by bolts or clips. A second slider 33 is detachably mounted on the side of the base mounting plate 3. The second slider 33 cooperates with the second guide rail 23, allowing the base mounting plate 3 and the horizontal beam 2 to be slidably connected via the second guide rail 23 and the second slider 33. In this way, the base mounting plate 3 can move horizontally to adjust its horizontal position. The top surface of the horizontal beam 2 has several limiting holes 27, and the side surface of the base mounting plate 3 is fixed with clips 34. When the base mounting plate 3 moves to the desired position, the clips 34 insert into the corresponding limiting holes 27 to achieve quick locking. This sliding and limiting mechanism makes the position adjustment of the base mounting plate 3 more convenient and accurate.

[0026] To facilitate position adjustment and improve accuracy, both the first guide rail 11 and the second guide rail 23 are equipped with scale markings. These markings can be directly engraved on the guide rail surface or applied as labels, indicating the distance traveled. For example, the scale markings on the first guide rail 11 can represent the vertical height value, while the scale markings on the second guide rail 23 can represent the horizontal displacement value. Operators can quickly adjust the component to the predetermined position according to the scale markings, reducing measurement time.

[0027] Handles 36 are fixed to both sides of the front of the base mounting plate 3. The handles 36 are usually metal or plastic handles and are fixed to the base mounting plate 3 by bolts or welding. During installation or maintenance, the operator can hold the handles 36 to easily move the base mounting plate 3, avoiding direct contact with other parts and improving safety and convenience.

[0028] To reduce vibration and noise, a shock-absorbing pad 7 is placed between the vertical support plate 4 and the switch mounting plate 5. The shock-absorbing pad 7 is made of rubber or silicone material and is installed at the connection between the vertical support plate 4 and the switch mounting plate 5. When the bolts are tightened, the shock-absorbing pad 7 is compressed, providing a cushioning effect, thereby reducing the transmission of vibration during the operation of the molded case switch 6 and extending the component life.

[0029] To facilitate the adjustment of the positions of the vertical support plate 4 and the switch mounting plate 5, scale markings are provided next to both the second oblong hole 32 and the third oblong hole 42. These scale markings indicate the position on the oblong holes; for example, a height scale is provided next to the second oblong hole 32, and a depth scale is provided next to the third oblong hole 42. Operators can directly refer to the scales during adjustment to ensure the accurate positioning of the molded case switch 6.

[0030] The above embodiments combine the features of each claim. Through the design of sliding structure, elongated hole connection and scale marking, the position of the molded case switch can be flexibly adjusted in multiple dimensions. At the same time, the convenience, stability and accuracy of installation are enhanced, and it is suitable for various low-voltage power distribution scenarios.

[0031] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
