Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of electrical cabinets, and particularly relates to a door plate with a glass window and an electrical cabinet. BACKGROUND

[0002] The existing electrical cabinet is configured with a door plate with glass. The glass can prevent accidental contact with live parts, and the state of the instruments and switches on the panel in the cabinet can be clearly observed through the glass. In addition, the glass can effectively prevent dust from falling and increase the aesthetic appearance of the cabinet, and has been increasingly popular and applied.

[0003] At present, the door plate with glass is relatively simple to design and install. A rectangular steel is arranged around the observation window of the door plate. The edges of the glass are pressed tightly by a pressing piece arranged on the rectangular steel, so as to install the glass on the door plate. When the pressing piece is pressed tightly, it is usually in point contact or line contact. However, after the glass is installed on the door plate, in the subsequent transportation process (with jolting) or in the use process (frequent opening and closing, which will inevitably cause vibration), the glass may be separated from the pressing piece and produce sliding or shaking, which is easy to cause damage. Therefore, the connection of the glass with the door plate by pressing is unstable and unreliable. SUMMARY

[0004] The purpose of the present application is to provide a door plate with a glass window and an electrical cabinet to solve the problem of poor connection stability of the glass with the door plate by pressing in the prior art. In order to achieve the above purpose, the present application solves the problem by the following technical scheme:

[0005] In a first aspect, the present application provides a door plate with a glass window, comprising a door plate body and a glass. The door plate body is provided with an observation window, and the glass is arranged on the observation window.

[0006] The top and bottom of the door plate body are each provided with a folded edge. Each of the folded edges is separately provided with a baffle and surrounds a mouth-shaped closed structure. The baffle is provided with a transversely arranged cutout for the glass to pass through, and the two ends of the cutout abut against the glass. The cutout is penetrated by a horizontal bar and fixedly connected with the baffle. The horizontal bar has two folded edges, one of which abuts against the door plate body, and the other folded edge linearly contacts and presses the glass. The folded edge of the horizontal bar on the bottom, which abuts against the door plate body, also abuts against the glass.

[0007] As a further technical scheme, a cooperation structure is arranged between the folded edge and the baffle. The baffle is positioned on the folded edge through the cooperation structure.

[0008] As a further technical scheme, the cooperation structure comprises at least one groove and a protrusion matched with the groove.

[0009] As a further technical solution, each of the folded edges and the baffles that surround it to form a closed square structure are an integral structure.

[0010] As a further technical solution, the horizontal bar has protrusions at both ends to prevent the entire horizontal bar from entering the cut, and is fixedly connected to the baffle through the protrusions.

[0011] As a further technical solution, the protrusion is detachably connected to the baffle.

[0012] As a further technical solution, a transparent gel is coated between the horizontal bar pressing the folded edge of the glass and the glass.

[0013] As a further technical solution, vertical strips are provided on both sides of the door panel body. Each vertical strip has two folded edges, one of which abuts against the door panel body, and the other folded edge contacts and presses against the glass.

[0014] As a further technical solution, the top and bottom baffles of the door panel body are arranged in a mirror image configuration.

[0015] In a second aspect, the present invention provides an electrical cabinet, comprising:

[0016] The main body of the electrical cabinet; and

[0017] The door panel, as described in the first aspect, is installed on the main body of the electrical cabinet.

[0018] The beneficial effects of the present invention are as follows:

[0019] (1) The two ends of the baffle cut of the present invention abut against the glass, which can position the left and right sides of the glass so that the glass does not sway left and right; the folded edge on the bottom horizontal bar abuts against the door panel body and also abuts against the glass, so that the folded edge of the horizontal bar holds the bottom of the glass so that it does not slide downward; in addition, the folded edge of the horizontal bar presses the glass, which can ensure the stability between the glass and the door panel under the premise that the glass is positioned on the left and right and the bottom.

[0020] (2) The present invention has a mating structure in the form of protrusions and grooves between the folded edge and the baffle. The baffle is positioned on the folded edge through the mating structure, which can better achieve positioning and installation during installation, prevent misalignment, and prevent the glass from being installed. The mating structure is also easy to set up.

[0021] (3) The horizontal bar of the present invention has two folded edges. The folded edges can not only abut against the door panel body to achieve the function of support, but also support the bottom of the glass to prevent it from sliding down, and at the same time press on the glass to press the glass tightly.

[0032] The technical solutions in typical embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0033] Example 1

[0034] like Figure 1 As shown, this embodiment provides a door panel with a glass window, including a door panel body 1 and a glass 8. The door panel body 1 is provided with an observation window, and the glass 8 is disposed on the observation window.

[0035] The top and bottom of the door panel body 1 are provided with folded edges. Each folded edge is individually equipped with a baffle and surrounds to form a U-shaped closed structure. The baffle has a horizontally arranged slit for the glass 8 to pass through, and the two ends of the slit abut against the glass 8. A horizontal strip passes through the slit and is fixedly connected to the baffle. The horizontal strip has two folded edges, one of which abuts against the door panel body 1, and the other folded edge contacts and presses against the glass 8. The folded edge on the bottom horizontal strip that abuts against the door panel body 1 also abuts against the glass 8.

[0036] The baffle has horizontally arranged slits for the glass 8 to pass through, and the two ends of the slits abut against the glass 8, which can position the left and right sides of the glass 8 so that the glass does not wobble from side to side; the folded edge on the bottom horizontal bar abuts against the door panel body 1 and also abuts against the glass 8, so that the folded edge of the horizontal bar supports the lower end of the glass 8 and prevents it from sliding downward; in addition, the folded edge of the horizontal bar presses the glass tightly, which can ensure the stability between the glass and the door panel under the premise that the glass is positioned on the left, right and bottom.

[0037] In this embodiment, as Figure 1 and Figure 2 As shown, the folded edge at the top of the door panel body 1 is the upper folded edge 110, and the folded edge at its bottom is the lower folded edge 120. The baffle that cooperates with the upper folded edge 110 is the upper baffle 2, and the baffle that cooperates with the lower folded edge 120 is the lower baffle 3. In this embodiment, the upper folded edge 110 and the lower folded edge 120 are integral with the door panel body 1 and are formed by bending the sheet metal of the door panel body 1.

[0038] like Figure 3 As shown, the upper folded edge 110 has two segments: a first folded segment 1101 perpendicular to the glass placement plate surface 150, and a second folded segment 1102 perpendicular to the first folded segment 1101 and parallel to the glass placement plate surface 150.

[0039] Similarly, the structure of the lower folded edge 120 is the same as that of the upper folded edge 110, except that the two are arranged symmetrically.

[0040] The structure of the upper baffle 2 in this embodiment is as follows: Figure 4As shown, it has a horizontal support 210 and a first leg 230 and a second leg 240 located at both ends of the horizontal support. In fact, the baffle 2 is an integral structure, formed by bending a flat plate, and a cut is made below the horizontal support 210 to form the first leg 230 and the second leg 240. The first leg 230 and the second leg 240 are arranged perpendicular to the horizontal support 210. The horizontal support 210 is fixedly connected to the second fold 1102 of the upper fold 110. The first leg 230 and the second leg 240 abut against the glass placement plate 150 of the door panel body 1, thereby forming a U-shaped structure around the upper fold 110 and the upper baffle 2.

[0041] The lower baffle 3 and the upper baffle 2 have the same structural parts, but the structural layout is different. Since one is on top and the other is on the bottom, the upper baffle 2 at the top and the lower baffle 3 at the bottom of the door panel body 1 are arranged in a mirror image, which is beneficial for the installation of the baffles.

[0042] In this embodiment, the upper folded edge 110 and the upper baffle 2 are processed separately and then welded together during installation. Similarly, the lower folded edge 120 and the lower baffle 3 are also processed separately. This separate arrangement is mainly beneficial for the initial processing.

[0043] In some other embodiments, each folded edge and the baffle that surrounds it to form a closed U-shaped structure are an integral structure. This method of connection is more reliable, but the process is more complicated. Since the two are an integral structure, there is no positioning problem.

[0044] A mating structure is provided between the folded edge and the baffle, and the baffle is positioned on the folded edge through the mating structure. That is, a mating structure is provided between the upper folded edge 110 and the upper baffle 2, and between the lower folded edge 120 and the lower baffle 3. This better achieves positioning during installation and prevents misalignment, which would prevent the glass from being installed.

[0045] The mating structure includes at least one groove 1103 and a mating protrusion 220, such as Figure 3 and Figure 4 As shown, a protrusion 220 is provided on the transverse support 210, and a groove 1103 is provided on the second fold 1102, with three protrusions 220 and three grooves 1103. It is understood that in other embodiments, the positions of the groove and the protrusion can be interchanged, and the protrusion 220 and the groove 1103 are used for positioning before welding.

[0046] like Figure 1 As shown, the upper baffle 2 is equipped with an upper horizontal bar 6, and the lower baffle 3 is equipped with a lower horizontal bar 10. The upper horizontal bar 6 and the lower horizontal bar 10 have the same structure. The structure of the horizontal bar is as follows: Figure 5As shown, it has two folded edges. One of the folded edges abuts against the door panel body 1, that is, against the glass placement panel 150. This folded edge is the supporting folded edge 640. The other folded edge contacts and presses against the glass 8. This folded edge is the pressing folded edge 630.

[0047] The height of the supporting fold 640 is higher than that of the pressing fold 630, specifically higher than the thickness of the glass 8, so that while the pressing fold 630 is pressing on the glass 8, the supporting fold 640 is exactly in contact with the glass placement plate 150, thus playing a supporting role.

[0048] The specific assembly drawing of the lower horizontal bar 10 is as follows: Figure 6 As shown, the pressing fold 630 presses against the glass 8, and the supporting fold 640 abuts against the glass placement plate 150 and supports the lower edge of the glass 8, thereby limiting the downward movement of the glass.

[0049] The specific assembly diagram of the upper horizontal bar 6 is shown in Figure 7. Its pressing fold 630 is pressed against the glass 8, and its supporting fold 640 abuts against the glass placement plate 150. Since the glass does not have an upward tendency, it does not support the upper edge of the glass 8.

[0050] like Figure 5 As shown, both ends of the upper horizontal bar 6 and the lower horizontal bar 10 are provided with protrusions 610 to prevent the entire horizontal bar from entering the cut, and are fixedly connected to the baffle plate through the protrusions 610. For easy assembly and disassembly, the protrusions 610 and the baffle plate are detachably connected. In this embodiment, as... Figure 4 As shown, the baffle plate has a first through hole 250, as... Figure 5 As shown, the protrusion 610 is provided with a second through hole 620, the first through hole 250 and the second through hole 620 are engaged and connected by screw 9.

[0051] like Figure 1 As shown, vertical strips are provided on both sides of the door panel body 1. The one on the inner side is the first vertical strip 7, and the one on the outer side is the second vertical strip 11. The vertical strip has two folded edges, one of which abuts against the door panel body 1, and the other folded edge contacts and presses against the glass 8.

[0052] The specific assembly diagram of the vertical strip is shown in Figure 8. Its pressing principle is the same as that of the horizontal strip. Before installation, multiple studs 5 are pre-welded onto the glass placement plate 150. The vertical strip is fixed and pressed in by the studs 5.

[0053] A transparent gel is applied between the horizontal bar pressing against the folded edge of glass 8 and glass 8 to reduce wear between the sheet metal parts and the glass, and to improve the dustproof effect of the door panel. Similarly, a transparent gel is also applied between the vertical bar and the glass.

[0054] like Figure 2As shown, the sides of the door panel body 1 are respectively provided with a first lateral folded edge 130 and a second lateral folded edge 140, and other components are arranged within the folded edges. Figure 1 As shown, a hinge 4 is installed on the inside of the door panel body 1 to achieve hinged connection with the cabinet.
