DETAILED DESCRIPTION

[0028] The specific embodiments of the present application are described in detail below. It should be understood that the specific embodiments described herein are merely illustrative and explanatory in nature and are not intended to limit the application.

[0029] In the present application, the orientation words such as "upper" and "lower" generally refer to the orientation in the assembled and used state, and "inner" and "outer" refer to the inner and outer relative to the outline of each component.

[0030] The present application provides an open type intelligent electrical switch cabinet based on sliding cabinet door, as shown in Figures 1 to 7 The sliding door structure includes a plurality of hollow door plates 1 of different sizes and nested in sequence from inside to outside, and a door frame 2 fixedly connected with the largest hollow door plate 1. The small hollow door plate 1 can slide in the largest hollow door plate 1. The side edge of the door frame 2 parallel to the sliding direction of the hollow door plate 1 is formed with a step 21 adapted to the size of each door plate 1.

[0031] Through the above technical solution, the hollow door plate 1 can slide in the original plane, thereby reducing the space occupied by the opening action of the cabinet door, making it more convenient to open the cabinet door, or selecting a larger size of the switch cabinet, and providing convenient properties for subsequent installation and maintenance.

[0032] Preferably, the sliding door structure is provided with two or three, which can increase the maintenance opening area of the cabinet body, and more conveniently maintain the internal components of the switch cabinet from multiple directions.

[0033] Preferably, the top plate, bottom plate and side plate are all hollow structures or hollow structures. Since the thermal conductivity of air is low, this setting can effectively isolate the temperature inside and outside the cabinet body, so that the internal components can operate stably in the environment of their own heat emission. Generally, the cabinet body is provided with a heat dissipation hole, and the cabinet body has a heat dissipation fan, which maintains and adjusts the internal temperature through the heat dissipation hole and the heat dissipation fan.

[0034] In order to avoid the hollow door plates 1 from separating from each other, in the preferred case, two adjacent hollow door plates 1 are respectively formed with a blocking part 41 and a collision part 42 at the connected ends, the blocking part 41 is formed on the inner wall of the end of the large hollow door plate 1, and the collision part 42 is formed on the outer wall of the end of the small hollow door plate 1, and the blocking part 41 can block the collision part 42 when the two adjacent hollow door plates 1 are fully expanded. Through this setting, the movement distance of the hollow door plate 1 can be limited, thereby avoiding the hollow door plates 1 from separating from each other, and improving the reliability of the sliding door structure.

[0035] In order to increase the sealing property to prevent dust and reduce the impact caused by the closing of the sliding door structure, in the preferred case, as shown in Figure 4 , Figure 5As shown, the blocking part 41 and / or the collision part 42 is provided with a sealing strip 5 on the side that can collide with the other. In other words, the side of the blocking part 41 facing the collision part 42 or the side of the collision part 42 facing the blocking part 41 is provided with a sealing strip. The hollow door plate 1 and / or the door frame 2 is provided with a sealing strip 5 at the part that can collide with the other, wherein the part that can collide on the door frame 2 includes the step 21 drop and the vertical rod 22 of the door frame 2 perpendicular to the sliding direction of the hollow door plate 1. Preferably, the sealing strip 5 is made of rubber, and the sealing strip 5 can be solid or a more easily deformed hollow structure. The sealing strip 5 needs to have space around it for deformation when installed.

[0036] In order to be able to lock the telescopic structure after the maintenance is completed, in the preferred case, the smallest hollow door plate 1 and vertical rod 22 are also provided with a locking structure for locking the hollow door plate 1 in the unfolded state, which includes a one-way ratchet rod 61 provided at the end of the hollow door plate 1, a lock groove 62, a reverse ratchet 63 and a spring part 64 provided in the vertical rod 22, the reverse ratchet 63, the spring part 64 and the lock groove 62 are connected in series, the direction of the reverse ratchet 63 is opposite to that of the ratchet on the one-way ratchet rod 61, and the one-way ratchet rod 61 can be locked in the lock groove 62 after pressing the reverse ratchet 63. Preferably, the spring part 64 is a spring. As Figure 6 As shown, the working process of the above arrangement is as follows: when the hollow door plate 1 is closed, the one-way ratchet rod 61 can enter the lock groove 62, the inclined surface of the one-way ratchet rod 61 can press the inclined surface of the reverse ratchet 63, causing the spring part 64 to compress, the reverse ratchet 63 to further penetrate into the lock groove 62, and the one-way ratchet rod to pass through, after which the vertical surface of the reverse ratchet 63 blocks the vertical surface of the one-way ratchet rod 61, thereby completing the locking action.

[0037] Further, the reverse ratchet 63 and the spring part 64 are arranged in two groups in sequence along the sliding direction of the hollow door plate 1, and the two groups of reverse ratchets 63 are respectively a first reverse ratchet and a second reverse ratchet, and the sealing strip 5 is respectively in an initial deformation state and a complete deformation state after the one-way ratchet rod 61 presses the first reverse ratchet and the second reverse ratchet; the locking structure further includes a magnetic metal 71 provided at the end of the hollow door plate 1 and an electromagnetic coil 72 provided on the vertical rod 22 capable of attracting the magnetic metal 71. Wherein, the "initial deformation state" refers to the state that the sealing strip 5 is just deformed and the deformation is small. The "complete deformation state" refers to the state that the sealing strip 5 is further pressed and deformed to a state that almost cannot be deformed. This arrangement can combine the advantages of electric and manual door closing, the first reverse ratchet can cooperate with the staff to manually close the telescopic door structure, which is safer and more reliable, and the second reverse ratchet can cooperate with the electromagnetic coil to magnetically attract and close, which is more compact and reduces the energy consumed by the staff for closing the door tightly, which is convenient to use.

[0038] Further, the minimum hollow door plate 1 is provided with a distance sensor for sensing the distance between the minimum hollow door plate 1 and the longitudinal rod 22, and the control device is electrically connected with the position sensor and the electromagnetic coil 72 respectively, and is used for receiving and processing the signal of the distance sensor and controlling the electromagnetic coil 72 to be energized.

[0039] In order to be able to open the telescopic door by a key, in a preferred case, the end of the reverse ratchet 63 away from the one-way ratchet rod 61 is provided with a control rod 66, the control rod 66 penetrates the lock slot 62 and is connected with a key module 65, the key module 65 is used to drive the reverse ratchet 63 to move through the control rod 66 to release the locking of the one-way ratchet rod 61. The key module 65 is a common lock and key on the market, and the lock needs to be pressed inward before it can be rotated after matching the correct key. The control rod 66 away from the reverse ratchet 63 is a rack, and the key module 65 and the control rod 66 are provided with a tooth surface and a smooth surface interval column structure, the column structure is fixedly connected with the key module 65 and located below the reverse ratchet 63. When the lock is pressed inward, the tooth surface of the column structure is engaged with the rack of the control rod 66, and when the lock is rotated, the tooth surface drives the rack to move.

[0040] In order to further improve the sealing effect and improve the stability of the movement of the hollow door plate 1, as shown in Figure 7 The hollow door plate 1 is provided with a double-sided groove 81, and the stepped portion 21 is provided with a clamping guide rail 82 corresponding to the groove 81 of each hollow door plate 1.
