Description

Technical Field

[0001] The utility model relates to the technical field of electrical cabinet installation, in particular to an auxiliary hanging tool for an electrical cabinet. Background Art

[0002] There are many ways to install an electrical cabinet, including hanging, vertical, and embedded installation. Hanging is a common installation method for electrical cabinets, especially suitable for occasions with limited space or where frequent maintenance and overhaul are required.

[0003] For outdoor mounted electrical cabinets, the typical installation method is to first install multiple expansion bolts horizontally on the wall. These expansion bolts are arranged vertically, corresponding to the upper and lower parts of the cabinet back. A connecting piece, spaced the same as the expansion bolts, is then fixed to the back of the upper part of the cabinet. The connecting piece is hooked onto the expansion bolts and tightened with nuts. The lower part of the cabinet is fixed in the same way as the upper part. However, this conventional fixing method requires that the spacing between the two connecting pieces be precisely aligned with the spacing between the two expansion bolts. If this is not the case, the cabinet cannot be mounted on the wall or may tilt after installation. This places high demands on the installation and is inconvenient.

[0004] Moreover, the connection between the nut and the expansion bolt is exposed on the outside. For the southern region with more rain and higher humidity, the nut is easily corroded by rain. For such electrical cabinets that require frequent maintenance, the frequency of disassembly and replacement of accessories is high, which makes it inconvenient to disassemble and replace. Utility Model Content

[0005] In order to solve the technical problems existing in the above-mentioned background technology, the utility model provides an auxiliary hanging tool for an electrical cabinet.

[0006] The technical solution of this utility model is as follows:

[0007] An auxiliary hanging tool for an electrical cabinet is arranged on the back of the electrical cabinet and connected to a plurality of expansion bolts arranged horizontally on the wall. The plurality of expansion bolts are distributed in parallel up and down, and include an upper connecting piece and a lower connecting piece distributed up and down on the back of the electrical cabinet;

[0008] The upper connecting piece is a "door"-shaped structure. A plurality of first long holes adapted to the expansion bolts above are opened in the horizontal direction on the side close to the wall. The expansion bolts above can slide in the horizontal direction with the first long holes. A first nut adapted to the expansion bolts above is provided on the inner side of the upper connecting piece. The upper connecting piece is detachably connected to the electrical cabinet on the side close to the back of the electrical cabinet.

[0009] The upper portion of the upper connecting member, close to the back side, is higher than the electrical cabinet and is provided with a first mounting hole corresponding to the first long hole;

[0010] The lower connecting piece is an "N"-shaped structure. The side of the lower connecting piece close to the wall is detachably connected to the expansion bolt below, and the other side opposite is detachably connected to the lower back of the electrical cabinet.

[0011] The upper connecting piece is used to connect the upper part of the electrical cabinet and the expansion bolts located above the wall. The first long hole has a certain length. When the upper connecting piece is installed on the expansion bolt above, there is no need to set a corresponding connecting piece on the back of the electrical cabinet according to the spacing of adjacent expansion bolts located on the same horizontal plane above, which makes installation and disassembly convenient; and the second long hole provided in the lower connecting piece has a certain width and length. There is no need to accurately measure the vertical spacing of the upper and lower expansion bolts. The lower expansion bolt can also be quickly aligned with the second long hole to fix the lower part of the electrical cabinet, thereby improving the overall installation efficiency of the electrical cabinet.

[0012] In order to facilitate drainage on the upper connecting plate on rainy days and prevent a large amount of rainwater from flowing through the expansion bolt to the first nut on the side of the upper connecting piece close to the wall, affecting the connection effect between the first nut and the expansion bolt, the upper end surface of the upper connecting plate is tilted downward toward the side close to the electrical cabinet, which can guide most of the rainwater to the side away from the wall.

[0013] The specific structure of the above-mentioned upper connecting member is that the upper connecting member includes an integrally formed first connecting plate, a second connecting plate and a third connecting plate. The first connecting plate and the third connecting plate are arranged vertically in parallel. The first connecting plate is arranged close to the electrical cabinet, and the first long hole is arranged on the third connecting plate.

[0014] In order to reduce the amount of rainwater flowing from the second connecting plate of the rainwater well to the upper end face of the electrical cabinet, a pad is connected between the first connecting plate and the back of the electrical cabinet. The upper end face of the pad is lower than the upper end face of the electrical cabinet, and the upper end face of the pad is tilted downward toward the side away from the electrical cabinet, forming a "V"-shaped groove between the pad and the first connecting plate, so that the rainwater guided by the second connecting plate does not pass through the upper end face of the electrical cabinet, but can flow out to the outside of the electrical cabinet through the upper end face of the pad, thereby preventing rainwater from corroding the upper end face of the electrical cabinet.

[0015] To facilitate installation of the first nut on the corresponding expansion bolt from the first mounting hole, the lowest level of the first mounting hole is set 1-5 cm higher than the top level of the electrical cabinet, thereby increasing the space for installing the first nut.

[0016] To facilitate installation of the first nut on the expansion bolt in the upper connector through the first mounting hole, the lowest height of the first mounting hole is set flush with the lowest height of the first long hole, and the width of the first mounting hole is greater than the width of the first long hole.

[0017] A plurality of second long holes adapted to the expansion bolts below are opened in the horizontal direction on one side of the lower connecting piece close to the wall, and the expansion bolts below can be slidably connected with the second long holes in the horizontal direction.

[0018] The above-mentioned lower connecting member includes an integrally formed fourth connecting plate, a fifth connecting plate and a sixth connecting plate. The fourth connecting plate and the sixth connecting plate are arranged in parallel, and the fourth connecting plate is connected to the electrical cabinet. The second long hole is arranged on the sixth connecting plate.

[0019] In order to prevent rainwater from drifting in from the side from flowing through the fifth connecting plate to the expansion bolt below, the upper end face of the fifth connecting plate is set as an inclined surface, tilted downward toward the side close to the fourth connecting plate, and forming a "V"-shaped groove structure with the fourth connecting plate, so that rainwater flows out of the two sides outside the electrical cabinet through the "V"-shaped groove structure formed by the fifth connecting plate and the fourth connecting plate.

[0020] The connection structure between the expansion bolt above and the third connecting plate is that a gasket is sleeved on the expansion bolt passing through the first long hole, the outer diameter of the gasket is larger than the width of the first long hole, and the first nut is arranged on the side of the gasket away from the third connecting plate and connected to the expansion bolt.

[0021] The beneficial effects of the present invention are:

[0022] The upper connecting piece is used to connect the upper part of the electrical cabinet to the expansion bolts located above the wall, and the lower connecting piece is used to connect to the expansion bolts located below. The connection method is to directly plug the first and second long holes into the corresponding expansion bolts and fix them with nuts. There is no need to accurately measure the spacing of the expansion bolts in the same horizontal direction and then punch holes in the electrical cabinet to connect the connecting piece for installation. The electrical cabinet can be adjusted in the horizontal direction under the guidance of the first and second long holes.

[0023] The upper expansion bolts are located below the second connecting plate, so that the upper connecting plate can play a waterproof role for the corresponding expansion bolts, and the second connecting plate can guide rainwater out of the upper connecting plate and guide the rainwater guided by the second connecting plate to both sides of the electrical cabinet through the pad with an inclined upper end surface to prevent rainwater accumulation;

[0024] The expansion bolts below are plugged into the second long holes and connected to the sixth connecting plate through the second nuts, so that the lower part of the electrical cabinet is fixed to the wall. The fifth connecting plate can protect the expansion bolts below from rainwater, and guide the rainwater coming in from the sides out of the two sides of the electrical cabinet through the fifth connecting plate with an inclined upper end face, so as to prevent rainwater from corroding the expansion bolts and the second nuts.

[0035] See also Figure 1 、 Figure 2 and Figure 3 As shown, an auxiliary hanging tool for an electrical cabinet 1 is installed on the back of the electrical cabinet 1 and connected to multiple expansion bolts 3 arranged horizontally on the wall 2. The multiple expansion bolts 3 are distributed parallel to each other up and down, including an upper connecting member 4 and a lower connecting member 6 distributed up and down on the back of the electrical cabinet 1. The upper connecting member 4 is used to connect the upper part of the electrical cabinet 1 to the expansion bolts 3 located above on the wall 2, and the lower connecting member 6 is used to connect to the expansion bolts 3 located below. The connection method is to directly insert the first long hole 431 and the second long hole 631 into the corresponding expansion bolt 3 and fix them with nuts. There is no need to accurately measure the spacing between the expansion bolts 3 in the same horizontal direction and then punch holes in the electrical cabinet 1 to connect the connecting piece for installation.

[0036] See also Figure 3 、 Figure 5 and Figure 6The upper connector 4 is a "door"-shaped structure, comprising an integrally formed first connecting plate 41, a second connecting plate 42, and a third connecting plate 43. The first connecting plate 41 and the third connecting plate 43 are arranged vertically and parallel to each other. The first connecting plate 41 is arranged near the electrical cabinet 1. The third connecting plate 43 is provided with a plurality of first elongated holes 431 in the horizontal direction, which are adapted to the expansion bolts 3 above. The number of first elongated holes 431 is the same as the number of expansion bolts 3 located on the same horizontal plane above. Generally, there are two expansion bolts 3 above. In this embodiment, the first elongated holes 431 are arranged between two of the same lines, which allows the expansion bolts 3 to be directly inserted into the corresponding first elongated holes 431 over a large range, facilitating quick connection. The expansion bolts 3 above and the first elongated holes 431 can slide horizontally. A first nut 7 adapted to the expansion bolts 3 above is provided on the inner side of the upper connector 4. The first connecting plate 41 is detachably connected to the upper portion of the back of the electrical cabinet 1 by bolts.

[0037] The connection structure between the above-mentioned expansion bolt 3 and the third connecting plate 43 is that a gasket 9 is sleeved on the expansion bolt 3 passing through the first long hole 431, and the outer diameter of the gasket 9 is larger than the width of the first long hole 431. The first nut 7 is arranged on the side of the gasket 9 away from the third connecting plate 43 and is connected to the expansion bolt 3 above.

[0038] To facilitate installation of the first nut 7 on the expansion bolt 3 in the upper connector 4 through the first mounting hole 411, the upper portion of the upper connector 4, near the back side, is higher than the electrical cabinet 1 and is provided with a first mounting hole 411 corresponding to the first long hole 431. To facilitate installation of the first nut 7 on the corresponding expansion bolt 3 from the first mounting hole 411, the lowest level of the first mounting hole 411 is set 1-5 cm higher than the highest level of the electrical cabinet 1, thereby increasing the space for installing the first nut 7. The lowest level of the first mounting hole 411 is set flush with the lowest level of the first long hole 431, and the width of the first mounting hole 411 is greater than the width of the first long hole 431. To further accommodate installation of the first nut 7 over a larger range, the length of the first mounting hole 411 is not less than the length of the corresponding first long hole 431.

[0039] In order to facilitate drainage on the upper connecting plate on rainy days and prevent a large amount of rainwater from flowing to the first nut 7 through the expansion bolt 3 on the side of the upper connecting piece 4 close to the wall 2, affecting the connection effect between the first nut 7 and the expansion bolt 3, the upper end surface of the second connecting plate 42 of the upper connecting plate is tilted downward toward the side close to the electrical cabinet 1, which can guide most of the rainwater to the side away from the wall 2.

[0040] In order to reduce the flow of the second connecting plate 42 of the rainwater well to the upper end surface of the electrical cabinet 1, a pad 5 is connected between the first connecting plate 41 and the back of the electrical cabinet 1. The upper end surface of the pad 5 is lower than the upper end surface of the electrical cabinet 1, and the upper end surface of the pad 5 is tilted downward toward the side away from the electrical cabinet 1, forming a "V"-shaped groove between the pad 5 and the first connecting plate 41, so that the rainwater guided by the second connecting plate 42 does not pass through the upper end surface of the electrical cabinet 1, but can flow out to the outside of the electrical cabinet 1 through the upper end surface of the pad 5, thereby avoiding rainwater corrosion of the upper end surface of the electrical cabinet 1. The upper end surface area of ​​the electrical cabinet 1 is large, and the surface is uneven, which may cause rainwater accumulation. The upper end surface of the pad 5 is set as an inclined surface, which facilitates the discharge of rainwater and reduces accumulation.

[0041] See also Figure 2 、 Figure 4 and Figure 7 The lower connecting member 6 shown is an "N"-shaped structure, including an integrally formed fourth connecting plate 61, a fifth connecting plate 62, and a sixth connecting plate 63. The fourth connecting plate 61 and the sixth connecting plate 63 are arranged in parallel, and the fourth connecting plate 61 is detachably connected to the electrical cabinet 1. The second elongated hole 631 is provided on the sixth connecting plate 63. The sixth connecting plate 63 is detachably connected to the expansion bolt 3 below via the second nut 8. The sixth connecting plate 63 is horizontally provided with a plurality of second elongated holes 631 adapted to the expansion bolt 3 below. The number of the second elongated holes 631 is consistent with the number of the expansion bolts 3 below. The number of the expansion bolts 3 below is two, and the expansion bolts 3 below can slide in the horizontal direction with the second elongated holes 631.

[0042] See also Figure 3 As shown, the expansion bolt 3 below is located below the fifth connecting plate 62 of the lower connecting plate, away from one end of the wall 2. The fifth connecting plate 62 shields one end of the expansion bolt 3 to prevent it from being corroded by rainwater. In order to prevent rainwater drifting in from the side from flowing through the fifth connecting plate 62 to the expansion bolt 3 below, the upper end face of the fifth connecting plate 62 is set as an inclined surface, which is inclined downward toward the side close to the fourth connecting plate 61 and forms a "V"-shaped groove structure with the fourth connecting plate 61, so that rainwater flows out of the two sides outside the electrical cabinet 1 through the "V"-shaped groove structure formed by the fifth connecting plate 62 and the fourth connecting plate 61.

[0043] See Figure Figure 3 The connection structure between the expansion bolt 3 below and the sixth connecting plate 63 is shown as follows: a gasket 9 is also sleeved on the expansion bolt 3 passing through the second long hole 631, and the outer diameter of the gasket 9 is larger than the width of the second long hole 631. The second nut 8 is arranged on the side of the gasket 9 away from the sixth connecting plate 63, and is threadedly fastened to the expansion bolt 3 below.
