Description

Technical Field

[0001] The utility model relates to the technical field of safe electrical equipment, in particular to a light and high-strength chassis of a safe electrical device. Background Art

[0002] Safety electrical device refers to a device that can be connected to the mains and achieve magneto-electric conversion. With the safety electrical device, the neutral wire and the live wire are isolated from the ground, and the current will not be directly conducted to the human body, and sparks and leakage will not be generated, making the electricity use process very safe. It can be widely used in hospitals, the military and other places.

[0003] At present, the existing safety electrical devices are generally divided into two layers in structure, the upper layer is used to install the control system, and the lower layer is used to install the electromagnetic conversion coil. For this structure, it is necessary to install a middle partition inside the chassis. There are two main ways to install the middle partition in the prior art: first, the middle partition is welded to the inner middle part of the chassis by welding, but in this way, the middle partition cannot be disassembled. When the middle partition is damaged, the entire chassis can only be replaced, and the maintenance cost is high; second, it is installed inside the chassis by bolts, and the entire middle partition will be located inside the chassis. In this way, the load-bearing strength and structural strength of the middle partition can only be given by the connecting bolts, and there is no support, so its load-bearing strength and structural strength are relatively low; moreover, the middle partition is installed inside the chassis, and the side of the middle partition will occupy part of the space inside the chassis, making it difficult to maximize the use space inside the chassis, thereby reducing the use effect of the chassis;

[0004] Based on the above problems, we propose a lightweight and high-strength chassis for a safe electrical device. Utility Model Content

[0035] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings:

[0036] like Figure 1-13 As shown,

[0037] A light and high-strength chassis for a safe electrical device, comprising a bottom plate 32, a first column 33, a second column 34, a third column 35, a fourth column 36 and a middle plate 37; the first column 33, the second column 34, the third column 35 and the fourth column 36 are fixedly connected to the four corners of the bottom plate 32 respectively; the bottom plate 32 is plugged with the middle plate 37 through the first column 33, the second column 34, the third column 35 and the fourth column 36; the middle plate 37 is provided with sockets 38 at locations corresponding to the first column 33, the second column 34, the third column 35 and the fourth column 36, and the first column 33, the second column 34, the third column 35 and the fourth column 36 are provided with supports 39; in this embodiment, the supports 39 on each column can effectively support the middle plate 37, and then fix it with bolts, so that the fixing effect of the middle plate 37 is better and the support The strength is relatively large; in addition, the middle plate 37 is sleeved (plugged) with each column, and the middle plate 37 wraps each column, and the contact area is increased. Compared with the prior art in which the middle plate 37 is installed inside the chassis by bolts, its structural strength will be greater; moreover, the outer side surface of the middle plate 37 will be exposed to the outside of the column, thereby making the internal use space of the chassis larger and the use effect better; in addition, during the disassembly process, there is no need to support the middle plate 37 (supported by the support 39) during the removal of the bolts on the support 39. After the four bolts are removed, the middle plate 37 can be pulled out. The difficulty of the disassembly and installation process is low, and it is easier to use. Moreover, in the prior art, when the middle plate 37 is screwed inside the chassis, the side of the middle plate 37 needs to have a side plate structure to facilitate the opening and screwing with the chassis, which will make the structure of the middle plate 37 relatively bulky, in sharp contrast to the lightweight structure of the middle plate 37 of the present application.

[0038] As a preferred embodiment; the support 39 and the middle plate 37 of the first column 33, the support 39 and the middle plate 37 of the second column 34, the support 39 and the middle plate 37 of the third column 35, and the support 39 and the middle plate 37 of the fourth column 36 are all fixedly installed by bolts; it can be understood that the support 39 and the middle plate 37 are provided with holes (as shown in the figure), which makes it easy to screw them together with bolts. Such a structure can make the middle plate 37 very firm and strong, and will not move.

[0039] As a preferred embodiment; the top surface of the support 39 of the first column 33, the top surface of the support 39 of the second column 34, the top surface of the support 39 of the third column 35 and the top surface of the support 39 of the fourth column 36 are all flush; the purpose of this design is to make the top surface of the middle layer board 37 flush, thereby improving the use effect of the middle layer board 37.

[0040] As a preferred embodiment; the bottom plate 32, the first column 33, the second column 34, the third column 35, the fourth column 36 and the middle plate 37 enclose a frame 2 structure, and the sides of the frame 2 are respectively connected to the side sealing plates 3 and the side door plates 4, and the side sealing plates 3 at one end of the frame 2 are protruding and connected to the top plate 5; it can be understood that by providing the side sealing plates 3 and the top plate 5, the top plate 5 abuts against the top of the side sealing plates 3, thereby reducing the installation gap of the side sealing plates 3 and reducing vibration noise; the top plate 5 can limit the upward movement of the side sealing plates 3, effectively preventing the side sealing plates 3 from opening, so that the overall installation strength of the side sealing plates 3 is relatively large, and when the top plate 5 is opened, the side sealing plates 3 can be opened without any tools. (Because it is hung), the function of quick release is realized, the difficulty of disassembly and installation is low, and the time of disassembly and installation is short. In addition, the side door panel 4 is screwed, and the purpose is to adjust the installation gap and installation strength between the side sealing panels 3 by adjusting its own position. Although the side door panel 4 is screwed, the number of door panels and screws is very small, and it can also be quickly installed and disassembled; if it is transported, the chassis can be quickly disassembled and then quickly installed after arriving at the destination. This process not only reduces the difficulty of transportation, but also does not waste too much time. Moreover, if a door panel is damaged, it can be quickly disassembled and replaced, which is beneficial to reduce the cost of use and maintenance, and the use effect is better.

[0041] As a preferred embodiment; the side sealing plate 3 includes a first side plate 6, a second side plate 7, a third side plate 8 and a fourth side plate 9, and the first side plate 6, the second side plate 7, the third side plate 8 and the fourth side plate 9 are respectively provided with a first hook 10, a second hook 11, a third hook 12 and a fourth hook 13; the frame 2 is respectively provided with a first hanging hole 14, a second hanging hole 15, a third hanging hole 16 and a fourth hanging hole 17 corresponding to the first hook 10, the second hook 11, the third hook 12 and the fourth hook 13; it can be understood that each side plate is provided with two symmetrically arranged hooks and two correspondingly connected hanging holes, and the hanging process is to correspond the hooks and the hanging holes, and insert the hooks into the hanging holes, and then move the side plate down, and then fix it to the frame 2 through the slot of the hook.

[0042] As a preferred embodiment; the top plate 5 is arranged at the top of the frame 2, and a mounting hole 18 is arranged on the top plate 5, and a connecting hole 19 is arranged on the frame 2 corresponding to the mounting hole 18, and the top plate 5 and the frame 2 are installed by bolts, and the top plate 5 is abutted against the side sealing plate 3; it can be understood that the function of the top plate 5 is to reduce the gap of the side sealing plate 3 and limit the movement of the side sealing plate 3, so it is arranged on the top of the frame 2, and the bolt installation is not only detachable, but also effectively ensures the stability of the connection of the top plate 5, and the mounting holes 18 are arranged at the four corners of the top plate 5.

[0043] As a preferred embodiment, the side door panel 4 includes a fifth side panel 20 and a sixth side panel 21, and the fifth side panel 20 and the sixth side panel 21 are respectively provided with a first screw rod 22 and a second screw rod 23; the frame 2 is respectively provided with a first screw hole 24 and a second screw hole 25 corresponding to the first screw rod 22 and the second screw rod 23. The fifth side panel 20 and the sixth side panel 21 are screwed, and when the fifth side panel 20 and the sixth side panel 21 are fixed, the position of the fifth side panel 20 can adjust the position of the third side panel 8, and then adjust the position of the second side panel 7 and the fourth side panel 9, and the position of the sixth side panel 21 can adjust the position of the second side panel 7, and then adjust the position of the first side panel 6 and the third side panel 8, so that the installation structure of the chassis is more compact and stable.

[0044] As a preferred embodiment; a limiting strip 26 is also provided on the first side panel 6, the second side panel 7, the fourth side panel 9 and the fifth side panel 20, and a limiting hole 27 is provided on the frame 2 at the limiting strips 26 corresponding to the first side panel 6, the second side panel 7, the fourth side panel 9 and the fifth side panel 20 respectively; by providing the limiting strip 26 and the limiting hole 27, the side sealing panel 3 or the side door panel 4 is better secured after being hung, and while reducing the number of hooks and screws used, it can also be ensured that they will not deviate.

[0045] As a preferred embodiment; the outer sides of the fourth side panel 9 and the fifth side panel 20 are hinged with a first door panel 28 and a second door panel 29 respectively, and the first door panel 28 and the second door panel 29 are connected to the fourth side panel 9 and the fifth side panel 20 through a door lock 30; by providing the first door panel 28 and the second door panel 29, it is convenient to open the door panel to connect and maintain the internal controller; in addition, in order to further ensure safety, the door lock 30 is used to lock the door panel to the fourth side panel 9 and the fifth side panel 20.

[0046] Specifically, the edges of the first side panel 6, the third side panel 8 and the sixth side panel 21 are all bent.

[0047] As a preferred embodiment; a card plate 31 is also provided inside the frame 2, a card strip is provided on the frame 2, a card plate 31 is inserted between the frame 2 and the card strip, and a receiving cavity is formed between the card plate 31 and the fourth side panel 9; the card plate 31 is provided for the purpose of installing the controller inside the receiving cavity, and then opening it through the first door panel 28 to facilitate wiring and maintenance. At the same time, this structure makes the structure of the chassis more compact and can effectively cooperate with the structural settings of other components.

[0048] The quick-disassembly principle of the utility model is: first remove the bolts on the top plate 5, and then open the top plate 5, then the side sealing plate 3 can be directly removed, and the side sealing plate 3 only needs to be lifted up so that the hook is aligned with the hanging hole, and the side sealing plate 3 can be easily taken out, and then the nuts on the side door plates 4 can be removed, and the side door plates 4 can be removed, and finally the bolts on the middle plate 37 are removed, and the middle plate 37 and the bolts on the detachable bottom plate 32 are directly pulled up to separate the bottom plate 32 from each column; the disassembly process of this chassis is less difficult, the disassembly and installation time is shorter, and there is no need to use more tools, and ordinary staff can operate it, and the use effect is better.

[0049] It should be pointed out that the main problems existing in the prior art are: the middle partition is directly screwed to the inside of the chassis, and the load-bearing strength and structural strength of the middle partition can only be given by the connecting bolts, without support, so that its load-bearing strength and structural strength are relatively low; moreover, the middle partition is installed inside the chassis, and the side of the middle partition will occupy part of the space inside the chassis, making it difficult to maximize the use space inside the chassis;

[0050] Therefore, through the improvements of the present application, the support strength and structural strength of the middle plate 37 during installation are greater. Moreover, since the middle plate 37 and the column are plugged in, the outer side of the middle plate 37 will be exposed to the outside of the column, thereby increasing the internal usable space of the chassis. Under the condition of the same volume, the internal usable space of the chassis can be maximized, thereby improving the use effect of the chassis.

[0051] The above implementation modes are merely descriptions of the preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering and technical personnel in the field shall fall within the protection scope determined by the claims of the present invention.
