[0051] Existing trolley-type switchgear includes multiple drawer units arranged in an array. The drawer units are equipped with moving contacts, and the cabinet body is equipped with stationary contacts. The moving contact is located at one end of the drawer unit near the stationary contact. For manual switchgear, especially those located above 1.8 meters above the ground, the moving and stationary contacts are out of the worker's field of vision when inserting or removing the drawer unit into the cabinet body. This can easily lead to misalignment between the moving and stationary contacts, damaging or even destroying the moving and / or stationary contacts. When the drawer unit is fully pulled out of the cabinet body, the moving contact may collide with the cabinet body, causing damage or even destruction to the moving contact.

[0052] The present invention provides a trolley type switch cabinet, such as Figure 1-3 As shown, the trolley-type switch cabinet includes a cabinet body 1, a drawer unit 2, a protective structure and a lifting mechanism 4. The cabinet body 1 is provided with a static contact; the drawer unit 2 is slidably plugged into the cabinet body 1, and the drawer unit 2 is provided with a moving contact 21; the protective structure includes a first protective structure 31 provided on the cabinet body 1, and a second protective structure 32 provided on the drawer unit 2. The static contact is located in the cavity of the first protective structure 31, and the moving contact 21 is located in the cavity of the second protective structure 32. The first protective structure 31 can be plugged into the second protective structure 32 so that the moving contact 21 is plugged into the static contact; the lifting mechanism 4 can drive the drawer unit 2 to rise and fall along the height direction of the cabinet body 1. Figure 1 The ab direction is the height direction of the cabinet 1.

[0053] The trolley type switch cabinet, such as Figure 1-3As shown, by setting the protective structure, in the process of plugging the drawer unit 2 into the cabinet 1, the second protective structure 32 is plugged into the first protective structure 31. When the drawer is plugged into place, the second protective structure 32 is plugged into the first protective structure 31 and plugged into place, and the moving contact 21 and the static contact are plugged in. It can be understood that only when the first protective structure 31 and the second protective structure 32 are normally plugged in and matched, the moving contact 21 and the static contact can be normally plugged in, thereby effectively avoiding the dynamic contact 21 and the static contact from being plugged in during the process of plugging the drawer unit 2 into the cabinet 1. Deviation may damage or even destroy the moving contact 21 and / or the static contact; secondly, by arranging a second protective structure 32 on the drawer unit 2, when the drawer unit 2 is pulled out of the cabinet body 1 and detached from the cabinet body 1, the second protective structure 32 can prevent the moving contact 21 from colliding with the cabinet body 1, thereby further avoiding damage or even destruction of the moving contact 21; by arranging a lifting mechanism 4, when the drawer unit 2 is completely pulled out of the cabinet body 1, the lifting mechanism 4 can drive the drawer unit 2 to rise and fall along the height direction of the cabinet body 1, thereby improving the practicality of the trolley-type switch cabinet.

[0054] Among them, Figure 1-4 As shown, the first protective structure 31 includes a base 312 and a first protective shell 311 arranged on the base 312. The base 312 is fixedly arranged on the cabinet 1. A limiting groove 3121 is provided on the base 312 along the four sides of the first protective shell 311. The second protective structure 32 can be plugged into the first protective shell 311 and plugged into the limiting groove 3121. By providing the limiting grooves 3121 around the first protective shell 311, it can be understood that when the second protective structure 32 is plugged into the first protective shell 311 and into the limiting grooves 3121, the moving contact 21 is plugged into the static contact, and the limiting grooves 3121 limit the plugging position of the second protective structure 32 into the first protective shell 311, thereby limiting the position of the moving contact 21, further avoiding the phenomenon of damage or even destruction of the moving contact 21 and / or the static contact due to the matching deviation between the moving contact 21 and the static contact during the process of plugging the drawer unit 2 into the cabinet 1; at the same time, the limiting grooves 3121 can also serve as a basis for judging whether the second protective structure 32 is plugged into place, thereby facilitating the judgment of whether the moving contact 21 is plugged into place.

[0055] Among them, Figure 1-7As shown, the second protective structure 32 includes a second protective shell 321 and an opening and closing door 322. The opening and closing door 322 is rotatably connected to the second protective shell 321. The opening and closing door 322 can close the chamber of the second protective shell 321. The first protective shell 311 can push the opening and closing door 322 to open the chamber of the second protective shell 321 and plug into the second protective shell 321. The second protective shell 321 can be plugged into the limiting groove 3121. By setting the opening and closing door 322 to be rotatably connected to the second protective shell 321, when the drawer unit 2 is pulled out of the cabinet 1, the first shell is separated from the second shell, the moving contact 21 and the static contact are separated, and the opening and closing door 322 closes the cavity of the second protective shell 321, thereby preventing the moving contact 21 from contacting the external environment, thereby further avoiding the moving contact 21 from being damaged or destroyed, and at the same time reducing the accumulation of debris and the like in the cavity of the second protective shell 321; when the drawer unit 2 is plugged into the cabinet 1, the first protective shell 311 can push the opening and closing door 322 to open the cavity of the second protective shell 321 and plug it into the second protective shell 321 until the second protective shell 321 is plugged into the limiting groove 3121, at which time, the moving contact 21 and the static contact are plugged into place. Specifically, as Figure 8 As shown, in this embodiment, the opening and closing door 322 is rotatably connected to the second protective shell 321 through a first torsion spring 324, and the opening and closing door 322 is an inward-opening door body.

[0056] Specifically, the first protective shell 311 and the second protective shell 321 are both rectangular shells.

[0057] Specifically, if Figure 7 and Figure 8 As shown, the second protective structure 32 further includes a stopper 323. When the opening and closing door 322 closes the chamber of the second protective shell 321, the opening and closing door 322 abuts against the stopper 323. By providing the stopper 323, the stopper 323 can limit the rotation range of the opening and closing door 322, preventing the opening and closing door 322 from rotating out of the chamber of the second protective shell 321. The hinge where the opening and closing door 322 is hinged to the second protective shell 321 and the stopper 323 are spaced apart along the height direction of the cabinet 1, and the hinge where the opening and closing door 322 is hinged to the second protective shell 321 is located above the stopper 323.

[0058] Specifically, if Figure 8 As shown, the limiting block 323 is provided with a guide surface 3231. Specifically, the guide surface 3231 is an inclined surface, which can guide the first protective shell 311 to be inserted into the second protective shell 321.

[0059] Specifically, if Figure 1-3 As shown, along the width direction of the drawer unit 2, handles 22 are provided on both sides of the drawer unit 2. By providing the handles 22, it is convenient to assemble or detach the drawer unit 2 from the cabinet body 1. Figure 1 The cd direction is the width direction of the drawer unit 2.

[0060] Among them, Figure 3 and Figure 9 As shown, the lifting mechanism 4 includes a first slide rail 41 fixedly mounted on the cabinet body 1 along the height direction of the cabinet body 1, a sleeve 42, and a connecting assembly. The sleeve 42 is slidably mounted on the first slide rail 41, and the connecting assembly is used to connect the sleeve 42 and the drawer unit 2. By disposing the first slide rail 41 on the cabinet body 1 along the height direction of the cabinet body 1 and the sleeve 42 slidably mounted on the first slide rail 41, the sleeve 42 can slide along the extension direction of the first slide rail 41; the drawer unit 2 is connected to the sleeve 42 via the connecting assembly, so that the sleeve 42 can drive the drawer unit 2 to slide along the extension direction of the first slide rail 41, thereby achieving the sliding sleeve 42 driving the drawer unit 2 to rise and fall along the height direction of the cabinet body 1, effectively improving the practicality of the trolley-type switchgear. It is understood that the height direction of the cabinet body 1 is parallel to the extension direction of the first slide rail 41.

[0061] Among them, Figure 9-11 As shown, the connecting assembly includes a connecting rod 431, one end of which is rotatably connected to the sliding sleeve 42, and the connecting rod 431 is configured to have a first position perpendicular to the first slide rail 41, and a second position parallel to the first slide rail 41; the connecting assembly also includes a roller 432 connected to the other end of the connecting rod 431, and a second slide rail 433 arranged on the drawer unit 2, and the second slide rail 433 is provided with an entrance end 4332 and an exit end 4333 along the length direction. When the connecting rod 431 is in the first position, the roller 432 can enter the second slide rail 433 from the entrance end 4332 and roll with the second slide rail 433. Specifically, by setting one end of the connecting rod 431 to be rotatably connected with the sliding sleeve 42, when the drawer unit 2 needs to be pulled out from the cabinet body 1, the connecting rod is first rotated to the first position, and then in the process of pulling the drawer unit 2 out of the cabinet body 1, the roller 432 enters from the entrance end 4332 of the second slide rail 433 and rolls along the second slide rail 433, and then the drawer unit 2 continues to be pulled out of the cabinet body 1, and the roller 432 rolls along the second slide rail 433 until the drawer unit 2 is completely pulled out of the cabinet body 1. It can be understood that after the drawer unit 2 is pulled out of the cabinet body 1, it is supported by the connecting assembly, and then the sliding sleeve 42 drives the connecting assembly and the drawer unit 2 to move synchronously along the extension direction of the first slide rail 41, so that the drawer unit 2 can be raised and lowered.

[0062] Specifically, if Figure 9As shown, in this embodiment, the first slide rail 41 is a hexagonal prism, and the slide sleeve 42 is provided with a hexagonal through hole. The slide sleeve 42 is mounted on the hexagonal prism. This allows the slide sleeve 42 to slide on the first slide rail 41. At the same time, the first slide rail 41 is configured as a hexagonal prism, so that the slide sleeve 42 can only slide along the extension direction of the first slide rail 41 and cannot rotate along the circumference of the first slide rail 41. This effectively prevents the slide sleeve 42 from driving the connecting rod 431 to rotate about the central axis of the first slide rail 41 and extend into the cabinet body 1, thereby ensuring that the drawer unit 2 can be normally withdrawn from the cabinet body 1. In other embodiments, the first slide rail 41 can also be a triangular prism, a quadrangular prism, a pentagonal prism, etc., as long as it can prevent the slide sleeve 42 from rotating along the central axis of the first slide rail 41.

[0063] Specifically, if Figure 11 As shown, the roller 432 includes a frame 4321 and a roller body 4322 rotatably connected to the frame 4321. The frame 4321 is fixedly connected to the connecting rod 431, and the roller body 4322 can roll on the second slide rail 433. More specifically, in this embodiment, the frame 4321 is rectangular, and the number of roller bodies 4322 is four. The four roller bodies 4322 are spaced apart along the circumference of the frame 4321, and the four roller bodies 4322 are arranged in a one-to-one correspondence with the four inner side walls of the second slide rail 433 and are in rolling engagement.

[0064] Specifically, if Figure 10 and Figure 11 As shown, the second slide rail 433 includes a rail body 4331 and two limit plates 4335 that are spaced apart and slidably connected to the rail body 4331. The outlet end 4333 of the rail body 4331 is provided with an opening 4334. The two limit plates 4335 can slide along the extension direction of the rail body 4331 and close the opening 4334. By setting an opening 4334 at the outlet end 4333 of the track body 4331, two limit plates 4335 are slidably connected to the track body 4331, and the two limit plates 4335 are slid so that the two limit plates 4335 can open or close the opening 4334. When the limit plates 4335 close the opening 4334, the two limit plates 4335 and the track body 4331 jointly form a second slide rail 433; when the limit plates 4335 open the opening 4334, the roller 432 rolls along the second slide rail 433 to the outlet end 4333, and separates from the second slide rail 433 at the opening 4334, thereby facilitating the disassembly of the drawer unit 2 and facilitating the repair or replacement of the drawer unit 2.

[0065] Specifically, the second slide rail 433 further includes two locking members (not shown), which are provided in a one-to-one correspondence with the two limiting plates 4335. The locking members are used to lock the limiting plates 4335 to the rail body 4331. Specifically, the rail body 4331 is provided with a plurality of threaded grooves (not shown) along its extension direction, and the limiting plates 4335 are provided with through holes (not shown). The locking members pass through the through holes and are screwed into the threaded grooves to lock the limiting plates 4335 to the rail body 4331. In this embodiment, the locking members are screws.

[0066] Among them, Figure 10 and Figure 11 As shown, the lifting mechanism 4 further includes a limit assembly 44 and an adjustment assembly 45. The limit assembly 44 includes a base 441 fixedly mounted on the cabinet 1, a support plate 442 rotatably connected to the base 441, and the adjustment assembly 45 can drive the support plate 442 to flip so that the support plate 442 has a third position in which it is plugged into the first slide rail 41, and a fourth position away from the first slide rail 41. When the support plate 442 is in the third position, the sliding sleeve 42 can be supported by the support plate 442. Specifically, when the adjustment assembly 45 drives the support plate 442 to flip to the third position, the support plate 442 is plugged into the first slide rail 41 and is perpendicular to the first slide rail 41. Thus, when the sleeve 42 drives the connecting assembly and the drawer unit 2 to move along the height direction of the cabinet body 1 to the support plate 442, the sleeve 42 abuts against the support plate 442, so that the support plate 442 supports the sleeve 42, the connecting assembly and the drawer unit 2; when the adjustment assembly 45 drives the support plate 442 to flip to the fourth position, the sleeve 42 can continue to drive the connecting assembly and the drawer unit 2 to move synchronously along the height direction of the cabinet body 1.

[0067] Specifically, if Figure 13 As shown, the support plate 442 is provided with a U-shaped groove 4421 . When the support plate 442 is plugged into the first slide rail 41 , the first slide rail 41 is located in the U-shaped groove 4421 .

[0068] Specifically, if Figure 13 As shown, the support plate 442 is rotatably connected to the base 441 and a second torsion spring 443 is provided between the support plate 442 and the base 441. The elastic restoring force of the second torsion spring 443 can also drive the support plate 442 to flip to a horizontal state.

[0069] Specifically, if Figure 9-12As shown, the adjustment assembly 45 includes two sets of third slide rails 451 and two adjustment blocks 452 spaced apart from each other on the base 441. The two adjustment blocks 452 are arranged in a one-to-one correspondence with the two sets of third slide rails 451 and are slidably connected. One end of the support plate 442 is located between the two adjustment blocks 452. The adjustment assembly 45 also includes a rotation button 453 and a telescopic rod 454. The ends of the telescopic rod 454 are respectively rotatably connected to one end of the two adjustment blocks 452. The rotation button 453 is fixedly connected to the telescopic rod 454 and rotatably connected to the base 441. The rotation button 453 can drive the telescopic rod 454 to rotate, causing the two adjustment blocks 452 to slide along the two sets of third slide rails 451 and flip the support plate 442. The rotation button 453 is located in the middle of the telescopic rod 454. By fixing the rotating button 453 to the telescopic rod 454 and rotating it to the base 441, when the rotating button 453 is rotated, the rotating button 453 drives the telescopic rod 454 to rotate, and the two adjustment blocks 452 are respectively rotated and connected to the two ends of the telescopic rod 454 and slide respectively on the two sets of third slide rails 451, so that the rotating button 453 drives the two adjustment blocks 452 to move in opposite directions along the third slide rails 451, thereby realizing the flipping of the support plate 442.

[0070] Specifically, the two sets of third slide rails 451 are respectively the first rail and the second rail, and the two adjustment blocks 452 are respectively the first adjustment block and the second adjustment block. The first adjustment block slides on the first rail, and the second adjustment block slides on the second rail. When the rotation button 453 is rotated in the first clockwise direction, the rotation button 453 drives the telescopic rod 454 to rotate, and the telescopic rod 454 drives the first adjustment block to approach the U-shaped groove 4421 of the support plate 442, and drives the second adjustment block away from the U-shaped groove 4421 of the support plate 442, thereby driving the support plate 442 to flip downward and away from the first slide rail 41; when the rotation button 453 is rotated in the opposite direction of the first clockwise direction, the rotation button 453 drives the telescopic rod 454 to rotate, and the telescopic rod 454 drives the first adjustment block away from the U-shaped groove 4421 of the support plate 442, and drives The second adjustment block approaches the U-shaped groove 4421 of the support plate 442, thereby causing the support plate 442 to flip upward and be inserted into the first slide rail 41, thereby causing the support plate 442 to reach the third position. When the rotation button 453 is further rotated in a direction opposite to the first clockwise direction, the rotation button 453 continues to rotate the telescopic rod 454, which drives the first adjustment block further away from the U-shaped groove 4421 of the support plate 442 and the second adjustment block further toward the U-shaped groove 4421 of the support plate 442, thereby causing the support plate 442 to continue to flip upward and away from the first slide rail 41. It is understood that the fourth position can be either a position in which the support plate 442 is flipped downward and away from the first slide rail 41 or a position in which the support plate 442 is flipped upward and away from the first slide rail 41. It is understood that when the rotation button 453 is released, the rotation button 453, under the action of the elastic restoring force of the second torsion spring 443, causes the support plate 442 to flip to a horizontal position.

[0071] In this embodiment, there are two lifting mechanisms 4, which are spaced apart along the width direction of the drawer unit 2. It is understood that the two lifting mechanisms 4 are located at both ends of the drawer unit 2 along the width direction to prevent the drawer unit 2 from tipping over after being fully withdrawn from the cabinet body 1.

[0072] There are multiple drawer units 2 , and the multiple drawer units 2 are arranged in sequence along the height direction of the cabinet 1 .

[0073] The specific structures of the drawer unit 2 and the cabinet body 1 belong to the prior art and will not be described in detail here.

[0074] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here.
