Description

Technical Field

[0001] The utility model relates to the technical field of distribution cabinets, and particularly relates to a distribution cabinet with an anti-misopening function. Background Technique

[0002] Distribution cabinets (boxes) are divided into power distribution cabinets (boxes), lighting distribution cabinets (boxes), and metering cabinets (boxes). They are the end devices of the power distribution system. Distribution cabinets are the general term for motor control centers. Distribution cabinets are used in occasions where the load is relatively dispersed and the number of circuits is small; motor control centers are used in occasions where the load is concentrated and the number of circuits is large. The distribution cabinet distributes the electric energy of a certain circuit of the upper-level power distribution equipment to the nearby load.

[0003] The distribution cabinet is composed of a cabinet body, a cabinet door, internal electrical components, and connecting wires. Most distribution cabinets are also equipped with cooling and heat dissipation components inside. All electrical components and circuits in the distribution board (box) should be in good contact and reliably connected; there should be no serious overheating or burning damage. The door of the distribution board (box) should be intact; the door lock should be kept by a special person.

[0004] However, in the prior art, the distribution cabinet does not have an anti-misopening function. Users can easily open the distribution cabinet inadvertently, increasing the probability of damage to the internal parts of the distribution cabinet and having a certain potential safety hazard. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is that the distribution cabinet does not have an anti-misopening function. Users can easily open the distribution cabinet inadvertently, increasing the probability of damage to the internal parts of the distribution cabinet and having a certain potential safety hazard.

[0006] In order to solve the above technical problems, the technical solution of the utility model is as follows:

[0007] A distribution cabinet with an anti-misopening function includes a distribution cabinet body. A rotating cabinet door is rotatably installed in front of the distribution cabinet body through a hinge. A fixing plate is fixed inside the distribution cabinet body. A connecting plate is fixed on the rear surface of the rotating cabinet door. A sliding insertion slot is provided at the front end of the fixing plate. The connecting plate is slidably inserted inside the sliding insertion slot. An installation slot is provided on the upper surface of the connecting plate. A limiting spring is clamped inside the installation slot. A limiting block is installed above one end of the limiting spring. The limiting block is rotatably installed inside the sliding insertion slot. A rotating block is provided at the bottom end of the limiting block. The bottom end of the rotating block contacts the end face of one end of the limiting spring.

[0008] Preferably, one end of the limiting block is inclined downward at an angle of 30 degrees. A clamping slot is provided at the downwardly inclined end of the limiting block. The top end of the rotating block is clamped inside the clamping slot.

[0009] Preferably, a rotating shaft is inserted through the top end of the rotating block, and both ends of the rotating shaft are rotatably inserted into the limiting blocks. The rotating block can only rotate counterclockwise under the restriction of the limiting blocks.

[0010] Preferably, a circular protrusion is provided in the middle of the limiting block, and a positioning shaft is inserted through the middle of the circular protrusion. Both ends of the positioning shaft are rotatably connected to the fixing plate.

[0011] Preferably, a rotating separation plate is installed below the rotating block, and a support shaft is inserted through one end of the rotating separation plate. The end of the support shaft is rotatably connected to the connecting plate.

[0012] Preferably, a magnet is fixed on the upper surface of the limiting block, and the magnet is magnetically adsorbed to the fixing plate.

[0013] Compared with the prior art, the present utility model has the following advantages:

[0014] 1. When the rotating cabinet door rotates under the influence of external force, the connecting plate slides inside the sliding insertion slot, but the limiting spring will be compressed instead of moving with the connecting plate. The compressed limiting spring will provide a force pointing to the fixing plate to the connecting plate and the rotating cabinet door, so that the connecting plate and the rotating cabinet door are reset, avoiding the accidental opening of the rotating cabinet door and ensuring the safety of the electrical components inside the power distribution cabinet;

[0015] 2. Pull the rotating cabinet door. After the rotating separation plate installed on the connecting plate leaves the sliding insertion slot, press down the end of the support shaft installed on the rotating separation plate, so that the other end of the rotating separation plate drives the rotating block and the limiting block to rotate around the axis of the positioning shaft, and makes the magnet on the upper surface of the limiting block adsorb to the fixing plate, then the limiting spring loses the restriction of the rotating block, separates the connecting plate from the inside of the sliding insertion slot, and enables the normal opening of the power distribution cabinet, without affecting the maintenance, repair or replacement of components inside the power distribution cabinet.

DETAILED DESCRIPTION

[0021] The specific implementation methods of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these implementation methods is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each implementation method of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0022] like Figures 1 to 4 As shown, a revolving cabinet door 2 is installed on the front of the distribution cabinet body 1 through hinge rotation, a fixed plate 3 is fixed on the inner side of the distribution cabinet body 1, a connecting plate 4 is fixed on the rear surface of the revolving cabinet door 2, a sliding plug-in slot 5 is provided at the front end of the fixed plate 3, the connecting plate 4 is slidably plugged into the inner side of the sliding plug-in slot 5, an installation slot 6 is provided on the upper surface of the connecting plate 4, a limiting spring 7 is clamped on the inner side of the installation slot 6, a limiting stopper 8 is installed above one end of the limiting spring 7, the limiting stopper 8 is rotatably installed on the inner side of the sliding plug-in slot 5, a rotating block 10 is provided at the bottom end of the limiting stopper 8, the bottom end of the rotating block 10 is in contact with one end face of the limiting spring 7, the limiting spring 7 is positionally limited by the limiting stopper 8 and the rotating block 10, to ensure that the connecting plate 4 cannot be completely detached from the inner side of the sliding plug-in slot 5, to prevent the revolving cabinet door 2 from opening accidentally.

[0023] As the preferred technical solution of this embodiment, one end of the limit stop 8 is tilted downward at an angle of thirty degrees, and a slot is provided at the downwardly tilted end of the limit stop 8. The top of the rotating block 10 is clamped in the inner side of the slot, and a rotating shaft 11 is inserted through the top of the rotating block 10. Both ends of the rotating shaft 11 are rotatably plugged with the limit stop 8. The rotating block 10 is restricted by the limit stop 8 and can only rotate counterclockwise. The rotating block 10 that can only rotate counterclockwise allows the limit spring 7 to enter the inner side of the sliding slot 5, but the limit spring 7 cannot leave the sliding slot 5 without external force intervention.

[0024] A circular protrusion is provided in the middle of the limit stop block 8, and a positioning shaft 9 is inserted through the middle of the circular protrusion. Both ends of the positioning shaft 9 are rotatably connected to the fixed plate 3. When the inclined end of the limit stop block 8 is subjected to an upward force, the limit stop block 8 rotates, so that the limit spring 7 can pass under the rotating block 10.

[0025] A rotating separation plate 12 is installed below the rotating block 10. One end of the rotating separation plate 12 is penetrated and inserted with a support rotating shaft 13. The end of the support rotating shaft 13 is rotatably connected to the connecting plate 4. A magnet is fixed on the upper surface of the limit stop block 8. The magnet is magnetically adsorbed and connected to the fixed plate 3. After the limit stop block 8 rotates upward, the magnet adsorbs to the fixed plate 3 to prevent the limit stop block 8 from resetting, ensuring that the limit spring 7 passes smoothly under the rotating block 10.

[0026] Working principle: When the rotating cabinet door 2 is closed, the connecting plate 4 is inserted into the inner side of the sliding insertion slot 5. After the end of the connecting plate 4 enters the sliding insertion slot 5, it will impact the rotating block 10. The rotating block 10 will drive the inclined end of the limit stop block 8 to move downward, causing the magnet on the upper surface of the limit stop block 8 to separate from the fixed plate 3. At the same time, the rotating block 10 rotates counterclockwise around the axis of the rotating shaft 11, causing the connecting plate 4 and the limit spring 7 to pass under the rotating block 10. After the connecting plate 4 completely enters the inner part of the sliding insertion slot 5, the rotating block 10 will naturally droop under the action of gravity and contact the end face of the limit spring 7. At this time, due to the restriction of the rotating block 10 on the end of the limit spring 7, when the rotating cabinet door 2 rotates under the influence of an external force, the connecting plate 4 slides inside the sliding insertion slot 5, but the limit spring 7 will be compressed instead of moving with the connecting plate 4. The compressed limit spring 7 will provide a force pointing to the fixed plate 3 to the connecting plate 4 and the rotating cabinet door 2, causing the connecting plate 4 and the rotating cabinet door 2 to reset, preventing the rotating cabinet door 2 from opening accidentally and ensuring the safety of the electrical components inside the power distribution cabinet. When it is necessary to open the rotating cabinet door 2, just pull the rotating cabinet door 2. After the rotating separation plate 12 installed on the connecting plate 4 leaves the sliding insertion slot 5, press down the end of the support rotating shaft 13 installed on the rotating separation plate 12, causing the other end of the rotating separation plate 12 to drive the rotating block 10 and the limit stop block 8 to rotate around the axis of the positioning rotating shaft 9, and making the magnet on the upper surface of the limit stop block 8 adsorb to the fixed plate 3, so that the limit spring 7 loses the restriction of the rotating block 10, separates the connecting plate 4 from the inner side of the sliding insertion slot 5, and enables the normal opening of the power distribution cabinet without affecting the inspection, maintenance or replacement of components inside the power distribution cabinet.

[0027] The above has described the embodiments of the present invention in detail in conjunction with the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, without departing from the principle and spirit of the present invention, various changes, modifications, substitutions and variations to these embodiments still fall within the protection scope of the present invention.
