Description

Technical Field

[0001] The utility model belongs to the technical field of low-voltage switch cabinets, and in particular relates to a perspective window anti-deformation structure. Background Art

[0002] At present, the perspective window of the door panel of the low-voltage switch cabinet is made of acrylic plate, which is a material with relatively high hardness. Since the low-voltage switch cabinet will generate heat during operation, the perspective window and door panel will absorb the heat, causing them to heat up and expand. The door panel is made of steel, and the thermal deformation of the door panel is much smaller than the thermal deformation of the perspective window. There will be a situation where the deformation of the door panel and the perspective window are inconsistent. At the same time, since the perspective window and the door panel are rigidly connected with bolts, the displacement between the perspective window and the door panel is limited. When the deformation of the perspective window is too large, due to insufficient deformation displacement space, the perspective window will be broken and damaged under the action of external force, causing unnecessary losses. Utility Model Content

[0003] In view of the defects or shortcomings in the prior art, the utility model provides a perspective window anti-deformation structure, which can make the perspective window expand and contract within a certain range when heated, thereby avoiding breakage and damage of the perspective window due to rigid connection.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] An embodiment of the utility model provides a perspective window anti-deformation structure, comprising a door panel, a perspective window and a pressure plate, wherein the perspective window is located between the door panel and the pressure plate, and a window is opened on the door panel, and the perspective window covers the window. The pressure plate is a rectangular frame structure, which is used to press the outer edge position of the perspective window; rivet screws are arranged at the four corners of the window, and the threaded ends of the rivet screws face the inner side of the door panel.

[0006] Furthermore, the size of the perspective window is larger than the size of the window.

[0007] Furthermore, first through holes are provided at four corners of the perspective window, and positions of the first through holes correspond one-to-one to positions of the rivet screws.

[0008] Furthermore, the diameter of the first through hole is greater than the diameter of the self-clinching screw.

[0009] Furthermore, a perspective hole is opened in the middle of the pressing plate, and the size of the perspective hole is smaller than the size of the perspective window.

[0010] Furthermore, second through holes are provided at four corners of the pressing plate, and positions of the second through holes correspond one-to-one to positions of the rivet screws.

[0011] Furthermore, a side plate is provided on the side of the pressing plate away from the perspective window, and the side plate is vertically arranged to the pressing plate.

[0012] Furthermore, the side panels are provided in plurality, and the plurality of side panels are fixedly connected end to end and fixed at the outer edge of the pressure plate.

[0013] Furthermore, lubricant is applied to the contact positions of the two sides of the perspective window with the door panel and the pressure plate respectively.

[0019] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0020] A typical implementation of the present utility model is as follows Figure 1 and Figure 2 As shown, a perspective window anti-deformation structure includes a door panel 1, a window 4 is formed on the door panel 1, and rivet screws 5 are arranged at the four corners of the window 4, and the threaded ends of the rivet screws 5 face the inner side of the door panel 1.

[0021] A perspective window 2 is arranged on the inner side of the window 4. The perspective window 2 is made of a transparent acrylic plate. The size of the perspective window 2 is larger than that of the window 4, so that the perspective window 2 can cover the window 4 to prevent foreign matter from entering the cabinet through the window 4. First through holes 6 are opened at the four corners of the perspective window 2. The positions of the first through holes 6 correspond to the positions of the rivet screws 5 one by one. The diameter of the first through holes 6 is larger than the diameter of the rivet screws 5, so that the rivet screws 5 can be inserted into the first through holes 6, thereby setting the perspective window 2 close to the inner side of the door panel 1.

[0022] Since the diameter of the first through hole 6 is larger than the diameter of the rivet screw 5 , when the perspective window 2 is deformed due to heat, a margin can be left for the expansion and contraction of the perspective window 2 , thereby avoiding the situation where the perspective window 2 breaks due to deformation without margin.

[0023] A pressure plate 3 is arranged on the side of the perspective window 2 away from the door panel 1. The pressure plate 3 is a rectangular frame structure. A perspective hole 7 is opened in the middle of the pressure plate 3. The size of the perspective hole 7 is smaller than that of the perspective window 2, so that the pressure plate 3 is used to press the edges of the perspective window 2.

[0024] Second through holes 8 are provided at the four corners of the pressure plate 3, and the positions of the second through holes 8 correspond one to one with the positions of the rivet screws 5, so that the rivet screws 5 can pass through the second through holes 8, thereby making the pressure plate 3 close to the outer surface of the perspective window 2. By passing the threaded ends of the rivet screws 5 through the first through holes 6 and the second through holes 8 in sequence and fixing them with nuts, the pressure plate 3 is used to press the edges of the perspective window 2, and the perspective window 2 is fixed between the door panel 1 and the pressure plate 3.

[0025] Since the contact area between the perspective window 2 and the door panel 1 and the pressure plate 3 is large, the friction between the perspective window 2 and the door panel 1 and the pressure plate 3 is reduced while ensuring that the position of the perspective window 2 is fixed. When the perspective window 2 is deformed by heat, the perspective window 2 can expand and contract within a certain range, thereby avoiding breakage and damage of the perspective window 2 due to rigid connection.

[0026] A side panel 9 is provided on the side of the pressing plate 3 away from the perspective window 2. The side panel 9 is vertically arranged to the pressing plate 3. There are four side panels 9, which are fixedly connected end to end and arranged at the outer edge of the pressing plate 3. By arranging the side panels 9, on the one hand, the overall strength of the pressing plate 3 can be increased to ensure that the pressing plate 3 is not deformed. On the other hand, the flatness of the pressing plate 3 is improved so that the pressing plate 3 can be completely fitted with the perspective window 2 to prevent the perspective window 2 from shaking due to incomplete fitting.

[0027] Lubricant is applied to the contact positions of the two sides of the perspective window 2 with the door panel 1 and the pressure plate 3 respectively. The lubricant has a certain high temperature resistance, which further reduces the friction between the perspective window 2 and the door panel 1 and the pressure plate 3.

[0028] The utility model arranges the perspective window between the door panel and the pressure plate, and uses the pressure plate to fix the perspective window. When the perspective window is deformed by heat, the door panel and the pressure plate do not restrict the deformation and displacement of the perspective window. The perspective window can be extended and retracted within a certain range, thereby avoiding breakage and damage of the perspective window caused by rigid connection.

[0029] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
