[0061] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0062] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the present invention provides a position-adjustable medium and low voltage complete switchgear cabinet, comprising a cabinet body 1, in which a plurality of equipment mounting plates 2 for installing electrical equipment are movably installed, and the equipment mounting plates 2 are arranged one by one along the height direction in the cabinet body 1.

[0063] An assembly slide rail 4 is installed along the height direction at the inner corner of the cabinet 1, and a slide seat 3 is installed at the corner of the equipment mounting plate 2. The slide seat 3 can slide on the assembly slide rail 4 to adjust the position of the equipment mounting plate 2 in the cabinet 1. The slide seat 3 can only slide along the direction of the assembly slide rail 4 to limit the direction of position adjustment of the equipment mounting plate 2.

[0064] In order to lock the position of the adjusted slide 3, specifically, a locking column 5 is installed on the side of the slide 3 away from the equipment mounting plate 2, and locking holes 6 are installed at equal intervals on the assembly slide rail 4;

[0065] The assembly slide rail 4 is composed of two symmetrical rail bodies 41, and the two rail bodies 41 can move back to back to drive the locking hole 6 to approach the vertical line opposite to the locking column 5, so that when the locking hole 6 is opposite to the locking column 5, the locking column 5 automatically pops out and is inserted into the locking hole 6. When the locking column 5 is inserted into the locking hole 6, the position of the slide seat 3 on the assembly slide rail 4 is locked and the position can no longer be adjusted up and down.

[0066] In order to unlock the device mounting plate 2 in the locked state, the present invention makes the following design, such as Figure 4 , Fig.10 As shown, an extrusion plate 7 is provided on the side of the assembly slide rail 4 away from the slide seat 3, and a plurality of push pins 10 are provided on the extrusion plate 7, and the push pins 10 correspond to the lock holes 6 one by one, wherein the extrusion plate 7 can move in a direction close to the assembly slide rail 4 to drive the push pins 10 to gradually extend into the lock hole 6, so that the lock pin 5 is pushed out of the lock hole 6.

[0067] When the locking post 5 is pushed out of the locking hole 6 , the locking post 5 can move along the assembly slide rail 4 to adjust the position of the equipment installation plate 2 in the cabinet 1 .

[0068] In the present invention, a single electrical device is placed on the device mounting plate 2. By adjusting the position of the slide seat 3 on the assembly slide rail 4, the position of the electrical device in the cabinet 1 and the distance between adjacent electrical devices can be adjusted. The distance between the electrical devices can be effectively controlled to achieve reasonable utilization of the space in the cabinet 1. The electrical devices are independently installed. The device mounting plate 2 is locked and unlocked by inserting the lock column 5 into the lock hole 6 and squeezing out the lock column 5. This facilitates installation and disassembly, and improves the convenience of later maintenance.

[0069] Furthermore, for electrical equipment that is not easy to dissipate heat, the distance between it and adjacent electrical equipment can be adaptively increased to improve the overall heat dissipation performance in the cabinet 1.

[0070] In the present invention, the rail body 41 can move. During the back-to-back movement between the rail bodies 41, the lock hole 6 follows the movement and moves to a vertical line opposite to the lock column 5. Specifically, a movable driving member 8 is connected to the end of the rail body 41, and the movable driving member 8 can drive the rail body 41 to move toward or away from each other.

[0071] The movable driving member 8 adopts the following preferred embodiments, as Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 and Fig.11 As shown, the movable driving member 8 includes a driving seat 81 installed in the top of the cabinet 1;

[0072] A driving groove 82 is provided in the driving seat 81, and a first connecting shaft 83 and a second connecting shaft 84 are connected to the top of the rail body 41 respectively. A first tooth block 85 is connected to the outside of the first connecting shaft 83, and a second tooth block 86 is connected to the outside of the second connecting shaft 84. The first tooth block 85 and the second tooth block 86 can move in the driving groove 82;

[0073] like Fig.12As shown, a limit seat 87 is installed at the bottom of the driving seat 81, and a long slot 88 is opened on the limit seat 87. The first connecting shaft 83 and the second connecting shaft 84 both pass through the long slot 88 and can move along the long slot 88. The width of the first tooth block 85 and the second tooth block 86 is greater than the width of the long slot 88.

[0074] During the movement of the first tooth block 85, the corresponding rail body 41 is driven to move through the first connecting shaft 83. During the movement of the second tooth block 86, the corresponding rail body 41 is driven to move through the second connecting shaft 84. The first tooth block 85 and the second tooth block 86 need to move in opposite directions or towards each other in order to drive the rail bodies 41 to move in opposite directions or towards each other.

[0075] In order to drive the first tooth block 85 and the second tooth block 86 to move toward or away from each other, the present invention further has the following design: a first transmission gear 89 and a second transmission gear 810 are disposed in the driving groove 82, the first transmission gear 89 is meshed with the first tooth block 85, and the second transmission gear 810 is meshed with the second tooth block 86;

[0076] A first driving gear 811 is coaxially mounted on the first transmission gear 89, and a second driving gear 812 is coaxially mounted on the second transmission gear 810. The first driving gear 811 and the second driving gear 812 are both mounted on the driving seat 81 via a shaft seat 813.

[0077] A movable rack 814 is arranged between the first driving gear 811 and the second driving gear 812. The first driving gear 811 is meshed with the movable rack 814, and the second driving gear 812 is meshed with the movable rack 814. The movable rack 814 can move in the driving groove 82 in a direction perpendicular to the first tooth block 85. A return spring 815 is arranged between the movable rack 814 and the driving groove 82.

[0078] The end of the movable rack 814 away from the return spring 815 is provided with a first inclined surface, and an extrusion block 816 is provided on the first inclined surface, and the bottom of the extrusion block 816 is in line with the first inclined surface;

[0079] like Figure 7 and Figure 8 As shown, the top of the extrusion block 816 is connected to a horizontal plate 817, and a top plate bottom groove 819 is provided on the top of the cabinet 1 for the horizontal plate 817 to move;

[0080] Among them, the movable rack 814 is driven to move by pressing down the horizontal plate 817, and the first drive gear 811 and the second drive gear 812 are driven to rotate under the meshing drive and drive the first transmission gear 89 and the second transmission gear 810 to rotate, so that the first tooth block 85 and the second tooth block 86 are driven to move towards each other or away from each other.

[0081] In the above embodiment, the downward pressing horizontal plate 817 can drive the movable rack 814 to move along the inside of the driving groove 82, thereby driving the first driving gear 811 and the second driving gear 812 to rotate in opposite directions. Under the meshing drive action, the first transmission gear 89 and the second transmission gear 810 also rotate in opposite directions, driving the first tooth block 85 and the second tooth block 86 to move in opposite directions, thereby driving the two rail bodies 41 to move in opposite directions.

[0082] The return spring 815 can provide driving force for the return process of the movable rack 814 .

[0083] In order to drive the horizontal plate 817 to rise and fall, the present invention makes the following design: an adjusting bolt 818 is threadedly installed on the top of the cabinet 1, and the bottom of the adjusting bolt 818 abuts against the surface of the horizontal plate 817.

[0084] By manually rotating the adjusting bolt 818, the bottom spiral of the adjusting bolt 818 can be driven to move downward, applying a downward pressure to the horizontal plate 817. Under the action of the pressure, the horizontal plate 817 moves downward, driving the extrusion block 816 to move downward. The downward movement of the extrusion block 816 can apply a horizontal thrust to the movable rack 814, pushing the movable rack 814 to move in the horizontal direction, thereby realizing the movement of the rail body 41.

[0085] When the adjusting bolt 818 is rotated in the opposite direction, the adjusting bolt 818 no longer applies downward pressure to the horizontal plate 817. At this time, due to the action of the return spring 815, the extrusion block 816 will be pushed upward by the movable rack 814, causing the extrusion block 816 to move upward, so that the horizontal plate 817 is always in contact with the bottom end of the adjusting bolt 818.

[0086] In order to prevent the horizontal plate 817 from falling off the first inclined surface and the second inclined surface when it drops to a certain height, and the horizontal plate 817 is likely to fall off the top of the cabinet 1, the present invention also makes the following design, such as Figure 5 As shown, the top plate bottom groove 819 opens downward, and limit strips 11 are provided on both sides of the opening position, and the distance between the limit strips 11 is smaller than the width of the horizontal plate 817 .

[0087] In the above embodiments, the limiting strip 11 can limit the height position of the horizontal plate 817 and prevent the horizontal plate 817 from moving downward before the first inclined surface and the second inclined surface separate.

[0088] The extrusion plate 7 can move in a direction close to the assembly slide rail 4 to drive the push column 10 to gradually extend into the lock hole 6, so that the lock column 5 is pushed out of the lock hole 6. Specifically, an extrusion driving member 9 is provided on the outer side of the extrusion plate 7, and the extrusion driving member 9 can push the extrusion plate 7 to move toward the side of the assembly slide rail 4;

[0089] The extrusion drive member 9 of the present invention adopts the following preferred embodiments, as Figure 6 and Figure 7 As shown, the extrusion drive member 9 includes a lifting plate 91 arranged on the back of the extrusion plate 7;

[0090] A plurality of first ladder blocks 92 are installed on the back of the extrusion plate 7, and a plurality of second ladder blocks 93 are installed on the side of the lifting plate 91 close to the extrusion plate 7. The first ladder blocks 92 correspond to the second ladder blocks 93 one by one and fit each other.

[0091] A telescopic spring is provided between the extrusion plate 7 and the side wall of the cabinet 1;

[0092] By pressing down the lifting plate 91 , the first ladder block 92 can be driven to move through the second ladder block 93 , so that the extrusion plate 7 moves toward the side of the assembly slide rail 4 , and the telescopic spring provides driving force for the resetting process of the extrusion plate 7 .

[0093] In the above embodiment, pressing down the lifting plate 91 can drive the second ladder block 93 to move downward, and the downward movement of the second ladder block 93 can push the first ladder block 92 to move toward the side of the assembly slide rail 4, so that the extrusion plate 7 moves toward the side of the assembly slide rail 4, and the push column 10 gradually extends into the lock hole 6, pushing the lock column 5 out of the lock hole 6 to achieve unlocking.

[0094] After unlocking, adjust the position of the equipment mounting plate 2. After adjusting the position, move the push column 10 out of the lock hole 6 and re-lock it. This requires keeping the lifting plate 91 pressed down during the process of adjusting the position of the equipment mounting plate 2. After the position is adjusted, release the downward pressure on the lifting plate 91, the lifting plate 91 and the squeezing plate 7 are reset, and the lock column 5 is re-inserted into the lock hole 6 to achieve locking.

[0095] When the extrusion plate 7 moves toward the assembly slide rail 4 , the deformation degree of the telescopic spring increases, and the pulling force exerted on the extrusion plate 7 also gradually increases.

[0096] In order to realize the driving of the lifting plate 91, the present invention makes the following design: the top of the lifting plate 91 is connected to a connecting column 94, the top of the connecting column 94 is connected to a connecting plate 95, and the connecting column 94 passes through the top of the cabinet 1;

[0097] It is assumed that there is a top plate groove 96 at the top of the cabinet 1, and the connecting plate 95 is movably installed in the top plate groove 96;

[0098] The adjusting bolt 818 passes through the connecting plate 95 .

[0099] By manually pressing down the connecting plate 95, the connecting column 94 is driven to move downward, thereby driving the lifting plate 91 to move downward, wherein the resetting process of the squeezing plate 7 can promote the resetting of the lifting plate 91. In order to further avoid obstruction of the resetting process, a corresponding spring can also be arranged between the bottom of the lifting plate 91 and the cabinet 1.

[0100] The movement direction of the lifting plate 91 is along its own height direction. To ensure that it moves in a specific direction, a slider can be set on the back of the lifting plate 91, and a vertical groove is set on the side wall of the cabinet 1. The slider slides in the groove to limit the movement direction of the lifting plate 91.

[0101] In the present invention, the locking column 5 should be a retractable structure, specifically, as Fig.13 As shown, the locking column 5 includes a main column 51 and a locking column 52 disposed in the main column 51;

[0102] A column slot is provided in the main column 51 for the clamping column 52 to move, and the clamping column 52 is connected to the bottom of the column slot via a connecting spring.

[0103] The outer wall of the locking column 52 fits with the locking hole 6 , and the outer diameter of the main column 51 is greater than the inner diameter of the locking hole 6 .

[0104] Under the action of the connecting spring, when the clamping column 52 is not inserted into the locking hole 6, the clamping column 52 is pressed against the surface of the rail body 41 to form a certain positive pressure. In this case, the clamping column 52 will inevitably form a certain friction force with the surface of the rail body 41 during the movement, which makes it possible for the entire equipment mounting plate 2 to be adjusted along the direction of the rail body 41 only under the action of external force. In the absence of external force, the friction force can position the equipment mounting plate 2 at a certain position on the rail body 41, but it is in an unstable state. In order to completely fix the position of the equipment mounting plate 2 on the rail body 41, it is necessary to use a locking column 5 for connection.

[0105] In order to enable the push pin 10 to completely squeeze into the lock hole 6 during the movement of the extrusion plate 7, the present invention also makes the following design: Figure 6 As shown, a movable track 12 for the extrusion plate 7 to move is provided in the cabinet 1, and the movable track 12 is used to limit the forward direction of the extrusion plate 7 to avoid deviation from the corresponding direction during the movement.

[0106] In summary, the main implementation process of the present invention is:

[0107] In the initial state, the rail bodies 41 are in a contracted state. After the electrical device is placed on the device mounting plate 2, upward or downward pressure is applied to the device mounting plate 2 to adjust the height position of the device mounting plate 2 on the rail body 41. During this process, the lock column 5 is not directly opposite to the lock hole 6, so the lock column 5 will not be stuck in the lock hole 6 during the up and down sliding process;

[0108] Under the condition that the lock column 5 is ensured to be flush with the lock hole 6 to be inserted, after all the equipment installation plates 2 are adjusted, the rail bodies 41 move back to back, the lock hole 6 gradually moves outward and faces the lock column 5, and the lock column 5 is inserted into the lock hole 6 to achieve the locking of the equipment installation plate 2;

[0109] When it is necessary to temporarily adjust the position of one or more electrical devices, the extrusion plate 7 is used to drive the push column 10 to push the lock column 5 out of the lock hole 6, and then pressure is applied to the corresponding equipment mounting plate 2 to adjust the position of the equipment mounting plate 2. After the adjustment, the extrusion plate 7 is reset, and the lock column 5 is re-inserted into the corresponding lock hole 6 to re-realize the locking after adjustment.

[0110] Therefore, during the initial process of loading electrical equipment into the cabinet 1, locking is achieved by contracting or expanding the driving rail body 41.
