Description

Technical Field

[0001] The invention relates to the technical field of power distribution cabinets, and in particular to a double-door power distribution device. Background Art

[0002] The distribution cabinet is divided into power distribution cabinet, lighting distribution cabinet and metering cabinet. It is the final equipment of the power distribution system. The distribution cabinet is a general term for the motor control center. The distribution cabinet is used in places where the load is relatively dispersed and there are fewer circuits; the motor control center is used in places where the load is concentrated and there are more circuits. They distribute the power of a circuit of the upper-level distribution equipment to the nearest load. This level of equipment should provide protection, monitoring and control for the load.

[0003] In the related art, a Chinese invention patent with publication number CN114400538A discloses a double-door power distribution device, including a cabinet with an opening on one side, a door frame fixed in the cabinet near the cabinet opening, an inner cabinet door hinged in the door frame, an outer cabinet door hinged at the cabinet opening outside the cabinet, a through hole is opened on the inner cabinet door at the electrical switch, four clearance holes are opened on the inner cabinet door around the through hole, and the four clearance holes are connected to the through hole; a baffle is hinged in each through hole, and the inner cabinet door is connected to each An elastic component is arranged between each baffle plate. When the baffle plate rotates to a first set position under the action of the elastic component, the baffle plate blocks the clearance hole. When the baffle plate overcomes the elastic action of the elastic component and rotates outward to a second set position, the baffle plate releases the blocking of the clearance hole so that the inner cabinet door can rotate from an open state to a closed state. Two supporting plates are fixed on the inner side wall of the inner cabinet door corresponding to each baffle plate. When the baffle plate rotates to the first set position, both ends of the baffle plate are respectively supported on the two supporting plates to block the clearance hole.

[0004] In the above-mentioned related technologies, when the inner cabinet door needs to be closed, the inner cabinet door is rotated toward the inside of the cabinet, and the switch pushes the baffle to rotate outward, so that the switch passes through the through hole. When the inner cabinet door is closed, the baffle rotates toward the inside of the cabinet under the elastic force of the elastic component, and the inner side of the baffle abuts against the support plate, so that the baffle closes the clearance hole. Since the baffle can only rotate toward the outside of the cabinet, when the cabinet door needs to be opened, the staff needs to rotate the baffle toward the outside of the cabinet to separate the baffle from the switch, so as to avoid the possibility of interference between the baffle and the switch when opening the inner cabinet door, which makes it inconvenient for the staff to open the inner cabinet door. Summary of the invention

[0005] In order to improve the problem that when the cabinet door needs to be opened, the staff needs to rotate the baffle toward the outside of the cabinet to separate the baffle from the switch electrical appliance, so as to avoid the possibility of interference between the baffle and the switch electrical appliance when opening the inner cabinet door, thereby making it inconvenient for the staff to open the inner cabinet door, the present application provides a double-door power distribution device.

[0006] The double-layer door power distribution equipment provided in this application adopts the following technical solution: A double-door power distribution equipment, comprising a cabinet body with an opening on one side, an outer cabinet door hinged at the opening of the cabinet body, a door frame fixed in the cabinet body, an inner cabinet door hinged in the door frame, characterized in that: a through hole for installing an electrical switch is opened on the side of the inner cabinet door, a blocking component for blocking the gap between the electrical switch and the inner wall of the through hole is arranged on the inner wall of the through hole, the blocking component comprises four baffles, the four baffles are respectively hinged on the four inner walls of the through hole, four elastic components are arranged on the inner cabinet door, the four elastic components correspond to the four baffles, and the elastic component is used to drive the baffle to block the gap between the electrical switch and the inner wall of the through hole.

[0007] By adopting the above technical solution, when the inner cabinet door needs to be closed, the inner cabinet door is rotated toward the inside of the cabinet body. During the closing process of the inner cabinet door, the electrical switch abuts against the baffle, and the baffle rotates toward the outside of the cabinet body. When the inner cabinet door is closed, the elastic component drives the baffle to rotate to a closed state, so that the baffle blocks the gap between the electrical switch and the inner wall of the opening. When the inner cabinet door needs to be opened, the cabinet door is rotated. When the baffle interferes with the electrical switch, when the inner cabinet door is rotated, the electrical switch pushes the baffle to rotate toward the inside of the cabinet body, thereby facilitating the staff to open the inner cabinet door.

[0021] By adopting the above technical solution, the movable box is slidably connected to the installation frame. When it comes to electrical switches of different thicknesses, the movable rod movable box can be used to adjust the thickness of the sealing box so that the thinner electrical switch can pass through the installation opening and be exposed, thereby making it easier for staff to inspect and repair the electrical switch.

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-5 This application is described in further detail.

[0032] The embodiment of the present application discloses a double-door power distribution device.

[0033] Example 1 Reference Figure 1 A double-door power distribution equipment comprises a cabinet body 1 with an opening on one side, a door frame 11 is fixed in the cabinet body 1, an inner cabinet door 12 is hinged in the door frame 11, and an outer cabinet door 13 is hinged at the opening of the cabinet body 1.

The blocking component 2 includes four baffles 21, which are rotatably mounted on the four inner walls of the through hole 14, respectively. Both end surfaces of the baffles 21 are provided with inclined surfaces 22, and the inclined surfaces 22 of two adjacent baffles 21 are in contact with each other.

[0035] Reference Figure 1 and Figure 2 , rotating blocks 23 are provided on both sides of the four baffles 21, the rotating blocks 23 are fitted with the side opposite to the baffles 21, and a rounded corner 27 is provided at one end of the rotating block 23 away from the symmetric center line of the inner cabinet door 12. Mounting blocks 26 are provided at both ends of the rotating block 23, the mounting blocks 26 are fixed to the side of the inner cabinet door 12, and the rotating block 23 is rotatably installed between the two mounting blocks 26. A plurality of mounting grooves 24 are provided on the side of the rotating block 23 close to the inner cabinet door 12, and the plurality of mounting grooves 24 are arranged at equal intervals along the length direction of the rotating block 23. A spring 25 is fixed on the inner side of the mounting groove 24 away from the inner cabinet door 12, and one end of the spring 25 close to the baffle 21 is fixedly connected to the side of the baffle 21.

[0036] When the inner cabinet door 12 needs to be closed, the inner cabinet door 12 is rotated toward the inside of the cabinet body 1. During the rotation of the inner cabinet door 12, the electrical switch abuts against the baffle 21, and the inner cabinet door 12 continues to be rotated. The electrical switch pushes the baffle 21 to rotate toward the outside of the cabinet body 1, and the spring 25 located on the inner rotating block 23 of the inner cabinet door 12 is in a stretched state. When the inner cabinet door 12 is closed, the baffle 21 rotates to a vertical state under the elastic force of the spring 25 on the inner rotating block 23 of the inner cabinet door 12, so that the baffle 21 blocks the gap between the through opening 14 and the electrical switch, thereby avoiding the possibility that the through opening 14 is opened too large, causing dust to enter the cabinet body 1 from the through opening 14.

[0037] Reference Figure 1 and Figure 2A plurality of rotating shafts 3 are provided on the side of the inner cabinet door 12. The plurality of rotating shafts 3 are respectively located on one side of the four inner corners of the through opening 14, and the rotating shafts 3 are rotatably connected to the inner cabinet door 12. Two positioning plates 31 are sleeved and fixed on the outer circumference of the rotating shaft 3. The two positioning plates 31 are respectively located on both sides of the inner cabinet door 12, and the opposite sides of the two positioning plates 31 are respectively in contact with one end of the two sides of the adjacent two baffles 21.

[0038] When the inner cabinet door 12 is closed, the four rotating shafts 3 are rotated respectively, and the rotating shafts 3 drive the two positioning plates 31 to rotate, so that the two positioning plates 31 are rotated to one end of two adjacent baffles 21, so that the two positioning plates 31 fix the baffles 21, thereby reducing the possibility that the spring 25 fails during long-term use and causes the baffles 21 to rotate, and the gap between the through port 14 and the electrical switch cannot be sealed.

[0039] The implementation principle of Example 1 is as follows: when the inner cabinet door 12 needs to be closed, the electrical switch pushes the baffle 21 to rotate toward the outside of the inner cabinet door 12 during the closing process. At this time, the spring 25 located on the inner mounting block 26 of the inner cabinet door 12 is in a stretched state. When the inner cabinet door 12 is closed, the baffle 21 rotates toward the inside of the cabinet body 1 under the elastic force of the spring 25 on the inner mounting block 26 of the inner cabinet door 12, so that the baffle 21 rotates to a vertical state, so that the baffle 21 blocks the gap between the electrical switch and the inner wall of the through-port 14; when it is necessary to When the inner cabinet door 12 is opened, during the opening process of the inner cabinet door 12, when the baffle 21 interferes with the electrical switch, the electrical switch drives the baffle 21 to rotate toward the inside of the cabinet body 1, so that the spring 25 located on the outer mounting block 26 of the inner cabinet door 12 is in a stretched state. When the baffle 21 is separated from the electrical switch, the baffle 21 rotates to a vertical state under the elastic force of the spring 25 on the outer mounting block 26 of the inner cabinet door 12, thereby reducing the need for the staff to drive the baffle 21 when opening the inner cabinet door 12, and making it easier for the staff to open and close the inner cabinet door 12.

The outer side of the mounting frame 4 is fixed with an annular outer edge 41, and the annular outer edge 41 fits with the side opposite to the inner cabinet door 12. The side corners of the annular outer edge 41 away from the inner cabinet door 12 are provided with through holes 42, and the outer side of the inner cabinet door 12 is provided with multiple threaded holes 43, and the multiple threaded holes 43 correspond to the multiple through holes 42. A bolt 44 is inserted into the through hole 42, and the bolt 44 passes through the through hole 42 and is inserted into the threaded hole 43, and the bolt 44 is threadedly connected to the inner wall of the threaded hole 43.

The bolts 56 are threadedly connected to the inner wall of the through holes 55. The end face of the bolts 56 abuts against the side of the fixed frame 51.

[0042] The implementation principle of the second embodiment is as follows: according to the thickness of the electrical switch, the moving box 52 is moved so that the electrical switch can pass through the installation opening 54 when the installation frame 4 is installed in the through opening 14. When the position of the moving box 52 is adjusted, the second bolt 56 is rotated so that the second bolt 56 abuts against the side of the fixed frame 51, thereby fixing the fixed frame 51 and the moving box 52. Then the installation frame 4 is inserted into the through opening 14 so that the annular outer edge 41 fits against the side opposite to the inner cabinet door 12, the through hole 1 42 is aligned with the threaded hole 43, the bolt 1 44 is inserted into the threaded hole 43 through the through hole 1 42, and the bolt 1 44 is rotated so that the head of the bolt 1 44 abuts against the side of the annular outer edge 41, thereby fixing the installation frame 4 on the inner cabinet door 12, and then the moving box 52 seals the gap between the electrical switch, thereby reducing the possibility of dust entering the cabinet 1 from the gap between the through opening 14 and the electrical switch.
