Abstract
Description
Technical Field
[0001] The invention relates to an electric power cabinet with an anti-injury function. Background Art
[0002] Power cabinets are divided into power cabinets, lighting cabinets and metering cabinets. They are the final equipment of the power distribution system. Power cabinets are used in situations where the load is relatively dispersed and there are fewer circuits. Motor control centers are used in situations where the load is concentrated and there are more circuits. They distribute the electrical energy 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] The power cabinet is a large cabinet, generally larger than a person. When a maintenance technician repairs or inspects the equipment in the power cabinet, the door of the power cabinet blocks the staff from certain angles, while other people who see the power cabinet with an open door at these angles will go over and close the door. Because the doors of existing power cabinets are easy to open and close at a high speed, it is easy to cause harm to the staff who are working when the door is closed. For this reason, the utility model patent with authorization announcement number CN202454912U discloses a power cabinet with an injury prevention function. By reducing the closing speed of the cabinet door, the maintenance technician is given more reaction time, thereby preventing the cabinet door from harming the maintenance technician. However, in actual use, it is found that some maintenance technicians are in a state of concentrated work in the power cabinet, so sometimes even if the cabinet door closes slowly, the maintenance technician still does not notice it, and the danger still exists. Summary of the Invention
[0004] The technical problem to be solved by the present invention is to provide an electric power cabinet with an anti-injury function and capable of limiting the position of the cabinet door.
[0005] The present invention adopts the following technical solutions:
[0006] The present invention includes a cabinet body, a cabinet door arranged on the cabinet body, a door opening device arranged between the cabinet body and the cabinet door, and a limiting device arranged at the bottom end of the cabinet body. A handle is provided on the side of the cabinet door away from the cabinet body, and a rectangular groove is provided on the side of the cabinet door close to the cabinet body. The limiting device is adapted to the cabinet door, and the rectangular groove is adapted to the door opening device.
[0007] The door opening device described in the present invention includes an L-shaped rotating rod A with one end hinged to the inner bottom surface of the cabinet body, a rotating rod B with one end hinged to the inner bottom surface of the cabinet body and located on the right side of the L-shaped rotating rod A, an L-shaped rotating rod C with one end hinged to the inner top surface of the cabinet body and opposite to the L-shaped rotating rod A, and a rotating rod D with one end hinged to the inner top surface of the cabinet body and opposite to the rotating rod B. The other end of the L-shaped rotating rod A and the other end of the rotating rod B are both hinged to the bottom surface of the rectangular groove, and the other end of the L-shaped rotating rod C and the other end of the rotating rod D are both hinged to the top surface of the rectangular groove.
[0008] A fixing rod is fixedly arranged between the bending part of the L-shaped rotating rod A and the bending part of the L-shaped rotating rod C in the present invention.
[0009] The L-shaped rotating rod A and the L-shaped rotating rod C of the present invention have the same shape and size.

[0011] The limiting device described in the present invention includes a support block located on the side of the cabinet body close to the cabinet door and fixedly connected to the bottom end of the cabinet body, a through groove arranged on the support block away from the cabinet body, a limiting column passing through the through groove and fixedly connected to the support block, a limiting plate located in the through groove, a through hole arranged on the limiting plate, and a limiting block fixedly arranged at one end of the limiting plate, the limiting column is located on the inner side of the through hole, the limiting block is located outside the through groove, and the width of the limiting block is greater than the width of the through groove.
[0012] The end of the limiting plate away from the limiting block is configured as a circumferential surface.
[0013] The corners of the through holes of the present invention are all chamfered.
[0014] The L-shaped rotating rod A, the rotating rod B, the L-shaped rotating rod C and the rotating rod D of the present invention are all made of insulating materials.
[0015] The support block, the limiting plate and the limiting block of the present invention are all made of hard materials.
[0016] The positive effects of the present invention are as follows:
[0017] 1. The door opening device of the present invention can close the cabinet door on the inner side of the cabinet body, or place the cabinet door on one side of the cabinet body, making it easy for maintenance technicians to see and saving cabinet space. The limit device can limit the cabinet door to prevent the cabinet door from automatically closing and causing harm to the working staff.
[0018] 2. The present invention pulls the cabinet door by the handle. The cabinet door is first pulled vertically out of the cabinet body under the action of the L-shaped rotating rods A and C, and then moves to the left side of the cabinet body under the action of the L-shaped rotating rods A, B, C and D.
[0019] 3. The fixing rod is fixedly arranged between the bending part of the L-shaped rotating rod A and the bending part of the L-shaped rotating rod C of the present invention so that the L-shaped rotating rod A and the L-shaped rotating rod C can maintain synchronization, thereby ensuring the stability of the cabinet door during the pulling process.

The limiting device is adapted to the cabinet door 2, and the rectangular groove 4 is adapted to the door opening device. The door opening device can close the cabinet door 2 on the inner side of the cabinet body 1, or place the cabinet door 2 on one side of the cabinet body 1, making it easy for the maintenance technician to be seen and saving space in the cabinet body 1. The limiting device can limit the cabinet door 2 to prevent the cabinet door 2 from automatically closing and causing harm to the staff who are working.
[0042] The door opening device of the present invention includes an L-shaped rotating rod A5 having one end hinged to the inner bottom surface of the cabinet body 1, a rotating rod B6 having one end hinged to the inner bottom surface of the cabinet body 1 and located to the right of the L-shaped rotating rod A5, an L-shaped rotating rod C7 having one end hinged to the inner top surface of the cabinet body 1 and opposite to the L-shaped rotating rod A5, and a rotating rod D8 having one end hinged to the inner top surface of the cabinet body 1 and opposite to the rotating rod B6. The other ends of the L-shaped rotating rod A5 and the other ends of the rotating rod B6 are both hinged to the bottom surface of the rectangular groove 4, and the other ends of the L-shaped rotating rod C7 and the other ends of the rotating rod D8 are both hinged to the top surface of the rectangular groove 4. By pulling the cabinet door 2 forward with the handle 3, the cabinet door 2 is first pulled vertically out of the cabinet body 1 under the action of the L-shaped rotating rod A5 and the L-shaped rotating rod C7, and then moves to the left side of the cabinet body 1 under the action of the L-shaped rotating rod A5, the rotating rod B6, the L-shaped rotating rod C7, and the rotating rod D8.
[0043] The fixing rod 9 is fixedly arranged between the bending part of the L-shaped rotating rod A5 and the bending part of the L-shaped rotating rod C7, so that the L-shaped rotating rod A5 and the L-shaped rotating rod C7 can be kept synchronous, ensuring the stability of the cabinet door 2 during the pulling process.
[0044] The L-shaped rotating rod A5 and the L-shaped rotating rod C7 of the present invention have the same shape and size, thereby ensuring the stability of the cabinet door 2 during the pulling process.
[0045] The rotating rod B6 and the rotating rod D8 of the present invention are of the same size and shape, thereby ensuring the stability of the cabinet door 2 during the pulling process.
[0046] The limiting device of the present invention includes a support block 10 located on a side of the cabinet body 1 close to the cabinet door 2 and fixedly connected to the bottom end of the cabinet body 1, a through slot 11 provided on the support block 10 away from the cabinet body 1, a limiting column 12 penetrating the through slot 11 and fixedly connected to the support block 10, a limiting plate 13 located in the through slot 11, a through hole 14 provided on the limiting plate 13, and a limiting block 15 fixedly provided at one end of the limiting plate 13, wherein the limiting column 12 is located on the inner side of the through hole 14, the limiting block 15 is located outside the through slot 11, and the width of the limiting block 15 is greater than the width of the through slot 11. When the cabinet door 2 needs to be pulled, the limiting block 15 is pulled up, at which time the limiting column 12 is located at one end of the through hole 14, and the limiting plate 13 is rotated in the through slot 11 so that the limiting block 15 is located below the support block 10, and the cabinet door 2 can move unhindered. When it is necessary to limit the cabinet door 2, pull up the limit block 15. At this time, the limit column 12 is located at one end of the through hole 14, and the limit plate 13 is rotated in the through groove 11 so that the limit block 15 is located above the support block 10. The limit block 15 is close to the cabinet door 2, and the top surface of the limit block 15 is higher than the bottom surface of the cabinet door 2. At this time, if the cabinet door 2 moves, it will hit the limit block 15. The lower end of the limit block 15 away from the cabinet body 1 is pressed against the top surface of the support block 10, making the limit block 15 unable to move, thereby completing the limitation of the cabinet door 2.
[0047] The end of the limiting plate 13 away from the limiting block 15 of the present invention is configured as a circumferential surface, which can facilitate the rotation of the limiting plate 13 in the through slot 11 when the limiting block 15 is pulled up.
[0048] The corners of the through hole 14 of the present invention are all chamfered, which can facilitate the rotation of the limiting post 12 in the through hole 14 .
[0049] The L-shaped rotating rod A5, the rotating rod B6, the L-shaped rotating rod C7 and the rotating rod D8 of the present invention are all made of insulating materials, which can protect the maintenance technicians and prevent leakage.
[0050] The support block 10 , the limiting plate 13 and the limiting block 15 of the present invention are all made of hard materials, specifically iron, which can prevent the cabinet door 2 from pushing the limiting block 15 open when limiting the cabinet door 2 .
[0051] During use, the cabinet door 2 is pulled forward by handle 3. L-shaped rotating rods A5 and C7 act upon the cabinet door 2 to first be pulled vertically out of the cabinet body 1. Then, L-shaped rotating rods A5, B6, C7, and D8 act upon the cabinet door 2 to move toward the left side of the cabinet body 1. When the cabinet door 2 needs to be pulled, the stopper 15 is pulled up. The stopper post 12 is now positioned at one end of the through hole 14. The stopper plate 13 is then rotated within the through slot 11, positioning the stopper 15 below the support block 10. The cabinet door 2 can then move unimpeded. When it is necessary to limit the cabinet door 2, pull up the limit block 15. At this time, the limit column 12 is located at one end of the through hole 14, and the limit plate 13 is rotated in the through groove 11 so that the limit block 15 is located above the support block 10. The limit block 15 is close to the cabinet door 2, and the top surface of the limit block 15 is higher than the bottom surface of the cabinet door 2. At this time, if the cabinet door 2 moves, it will hit the limit block 15. The lower end of the limit block 15 away from the cabinet body 1 is pressed against the top surface of the support block 10, making the limit block 15 unable to move, thereby completing the limitation of the cabinet door 2.
[0052] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
