Description

Technical Field

[0001] The utility model relates to the technical field of switch cabinets, in particular to a combined hinge fixing structure for closing a door gap with a side strip of a switch cabinet frame. Background Art

[0002] The protection level of the switch cabinet involves the door gap standard when the equipment is running and the cabinet door is closed. The protection level requirements for the equipment user scenario are: cabinet door protection level IP40, door gap no greater than 1.0mm, and user equipment with protection level is basically considered to meet the standard. However, in order to achieve 100% compliance with the industry manufacturing process cabinet door gap standard, the only way to solve this problem is to add a sealing strip, or to install glass and sealing strips.

[0003] The main reason for the large gaps in cabinet doors in the industry is that the hinge side of the cabinet back door is larger than 1.0mm, which is common. The deformation during manufacturing bending is larger than 1.0mm. The failure to meet the standard for the assembly accuracy of the cabinet frame is also a reason. When the cabinet door is closed, the deformation of the middle section of the door is larger than the upper and lower ends of the door. It is normal for the middle section of the door to be larger than 1.0mm. When installing adhesive sealing strips on the hinge side of the cabinet door, a notch needs to be cut at the hinge position. Opening and closing the door will also scrape the sealing strips, which are easy to fall off over time. It is still feasible to glue the sealing strips on the other three sides of the cabinet door. The normal cost of adhesive sealing strips is 2 yuan per meter. The cost of using glass doors is higher. Rubber sealing strips need to be installed on glass doors to solve the problem of meeting the door gap standards, and the protection level can also be improved.

[0004] The gap between the cabinet doors is larger than 1.0mm. For the storage environment when the equipment arrives at the site, such as humidity and heavy dust from infrastructure construction, dust and moisture will accumulate at the exposed electrical connections of the equipment, causing the electrical performance to deteriorate. In the event of an accident, the insulation voltage test of electrical components is only 100V, while the standard is 690V or 1000V. It is very difficult to clean the dust at the electrical connections, which can only be solved by cleaning with alcohol. If the dust is not cleaned thoroughly, the heat dissipation of the equipment will be affected, and the surface coating will be easily oxidized, resulting in equipment failure. The insulator voltage drops, the temperature of the electrical connection point rises, the door gap is large, and for the equipment operation scenario, the salt fog air and high humidity, air pollution particles, and polluted gases enter the equipment, which will cause strong corrosion to the electrical connection points, deteriorate the electrical performance, and reduce the insulation voltage. Therefore, the gap between the switch cabinet door is less than 1.0mm, the coordination process between the cabinet frame and the cabinet door body is very difficult, the use of glass doors is costly, one device costs about 1,000 yuan, and the cabinet width is 630mm, the horizontal busbar is added, and the copper consumption of one device is 2.6 to 4kg, and the equipment occupies more space.

[0044] like Figures 1 to 17 As shown, a switch cabinet frame side strip closed door gap combined hinge fixing structure, comprising:

[0045] Door hinge, the door hinge is used for the installation of the cabinet door, the door hinge comprises a support hinge 1 and an outer door hinge 2, the support hinge 1 and the outer door hinge 2 are hinged through a hinge shaft 3;

[0046] The cabinet door is installed by door hinges, the outer door hinge 2 is fixed on the cabinet door, the support hinge 1 is located on the side of the cabinet door, and the hinge shaft 3 is located on the front of the cabinet door;

[0047] The door gap closing edge strip 4 is fixed to the front of the cabinet frame structure on the side of the cabinet door, and the door gap closing edge strip 4 is arranged close to the side of the cabinet door, and is used to close the door gap between the cabinet door and the cabinet frame structure on the side of the cabinet door. The door gap closing edge strip 4 cooperates with the side of the cabinet door to control the door gap between the door gap closing edge strip 4 and the cabinet door;

[0048] The door hinge fixing side of the cabinet door is provided with a door gap sealing strip 4, and the door gap sealing strip 4 on the door hinge fixing side of the cabinet door has a clearance notch 5 for making way for the door hinge. The door lock side of the cabinet door is also provided with a door gap sealing strip 4.

[0049] The switch cabinet of this embodiment is specifically a low-voltage switch cabinet, the cabinet door is specifically a cabinet rear door 6, the cabinet frame structure on the side of the cabinet door is specifically a frame column 12, the cabinet rear door 6 is installed on the front side of the frame column 12 through a door hinge, and the door gap closing strip 4 is fixed on the front side of the frame column 12.

[0050] like Figure 1 , 6 As shown in Figure 7, the door gap sealing strip 4 is a long strip structure of a specific U-shaped groove, including an outer plate 4-1, a front plate 4-2 and a back plate 4-3. The outer plate 4-1 is located on the outer side of the door gap sealing strip 4, the front plate 4-2 is located on the front of the door gap sealing strip 4, and the back plate 4-3 is located on the back of the door gap sealing strip 4. The outer plate 4-1, the front plate 4-2 and the back plate 4-3 form a U-shaped groove, and the U-shaped groove extends along the length direction of the door gap sealing strip 4. The opening of the U-shaped groove is located on the inner side of the door gap sealing strip 4 facing the cabinet door. The upper and lower ends of the door gap sealing strip 4 are blocked by end blocking pieces 10, the back plate 4-3 is in close contact with the frame column 12, and the inner side 4-2-1 of the front plate 4-2 cooperates with the cabinet door to control the door gap between the door gap sealing strip 4 and the cabinet door. Of course, it is not ruled out that the upper and lower ends of the door gap sealing strip 4 are blocked by their own structure.

[0051] like Fig.14 As shown, the specific structure of the inner side 4-2-1 of the panel 4-2 of the door gap closing strip 4 on the fixed side of the door hinge cooperating with the cabinet door is: the inner side 4-2-1 of the panel 4-2 of the door gap closing strip 4 on the fixed side of the door hinge extends toward the cabinet door and covers the front of the cabinet body, and the coverage area of ​​the inner side 4-2-1 of the panel 4-2 on the front of the cabinet body does not exceed the axis of the hinge shaft 3, so as to prevent the inner side 4-2-1 from interfering with the opening of the cabinet door.

[0052] The inner edge 4-2-1 of the panel 4-2 of the door gap closing strip 4 on the fixed side of the door hinge covers the front side of the cabinet body, and the advantage of achieving overlapping fit is that due to the bending process, there will be a dimensional error of ±0.5mm between the upper and lower ends of the cabinet door, and the overlapping width of the panel 4-2 of the door gap closing strip 4 and the cabinet body can be set to 1.5mm. Even if the upper end of the cabinet door falls, the door gap between the door gap closing strip 4 and the cabinet door is still in a closed state.

[0053] like Fig.13As shown, the specific structure of the inner side edge 4-2-1 of the panel 4-2 of the door gap sealing strip 4 on the door lock side cooperating with the cabinet door is: the inner side edge 4-2-1 of the panel 4-2 of the door gap sealing strip 4 extends to the side of the cabinet door, and is matched with the clearance of the side of the cabinet door to prevent the inner side edge 4-2-1 from interfering with the opening of the cabinet door. More specifically, the panel 4-2 of the door gap sealing strip 4 is matched with the clearance at the door bending angle 9 on the side of the cabinet rear door 6, and the matching clearance is controlled at 0.3mm, which effectively prevents the paint at the door bending angle 9 on the side of the cabinet rear door 6 from being damaged when the door is opened.

[0054] like Fig.16 and 17 As shown, the length of the door gap closing strip 4 is determined according to the height of the cabinet door. Each door gap closing strip 4 is adapted to a cabinet door. The end sealing member 10 has an extension portion 10-1 extending toward one side of the cabinet door, which is used to control the door gap at the upper edge of the cabinet door. The extension portion 10-1 has a sealing tip 10-1-1, and the shape of the sealing tip 10-1-1 is adapted to the gap between the bent edges of the cabinet body beam 11 and the frame column 12.

[0055] The door gap closing edge strip 4 is fixed to the frame column 12 by fixing screws 13, the back panel 4-3 has a mounting hole 14 adapted for the fixing screws 13, the panel 4-2 has a transition hole 15 allowing the fixing screws 13 to enter the door gap closing edge strip 4, and the transition hole 15 is blocked by a transition hole blocking piece 16.

[0056] The door gap closing edge strip 4 is specifically a metal profile, more specifically an aluminum profile, and the end blocking piece 10 and the transition hole blocking piece 16 are specifically plastic parts.

[0057] like Figure 4 As shown, the support hinge 1 includes a fixed section 1-1 and an extended section 1-2, the fixed section 1-1 and the extended section 1-2 are L-shaped structures, the fixed section 1-1 is located at the rear end of the extended section 1-2, and the front end of the extended section 1-2 is hinged to the outer door hinge 2 through a hinge shaft 3; Fig.14 As shown, the fixed section 1-1 is located on the side of the extending section 1-2 facing away from the cabinet door. The fixed section 1-1 is padded on the back panel 4-3 and fixed to the frame column 12 together with the back panel 4-3 by fixing screws 13. The fixed section 1-1 has a mounting hole 14 adapted to the fixing screws 13.

[0058] The mounting holes 14 on the back plate 4 - 3 correspond to the modular holes on the frame columns 12 .

[0059] like Figure 4 and 14As shown, the front end of the extended section 1-2 of the support hinge 1 is rolled to form an axis fixing hole 1-3. The outer door hinge 2 is fixed to the front of the cabinet rear door 6. The hinge side of the outer door hinge 2 has an axis positioning hole 2-1, and the middle position of the hinge side has a notch for embedding with the front end of the support hinge 1. The hinge axis 3 is inserted into the axis positioning hole 2-1 and the axis fixing hole 1-3 to achieve the hinge connection between the support hinge 1 and the outer door hinge 2. The back of the outer door hinge 2 has a door fixing cylinder 2-2 and a mounting hole 14. Figure 8 and 9 As shown, a fixing hole corresponding to the door fixing cylinder 2-2 of the outer door hinge 2 is provided on the cabinet rear door 6. The outer door hinge 2 is inserted into the fixing hole of the cabinet door through the door fixing cylinder 2-2 for installation and positioning, and then fixed by screwing the fixing screw 13 into the installation hole 14 of the outer door hinge 2.

[0060] The hinge shaft 3 is exposed outside the cabinet rear door 6 and the door gap closing edge strip 4, which facilitates the installation of the hinge shaft 3.

[0061] like Fig.10 As shown, the rear door 6 of the low-voltage switch cabinet has a small door and a small door, the upper one is a small door, and the lower one is a small door.

[0062] Since the support hinge 1 is located on the side of the door hinge fixing side of the cabinet door, and the hinge shaft 3 is located on the front of the cabinet door, the door opening angle can reach 180°. By controlling the length of the exposed round head of the transition hole blocking member 16 that closes the transition hole 15, the door opening angle is controlled to 155° to prevent the door from opening too wide and colliding with the rear door 6 of another switch cabinet, causing damage to the surface.

[0063] The measurement standard for the door gap of the switch cabinet is to measure the door gap between the curved edge of the cabinet door side and the frame column 12 from the side of the cabinet door. The protection level standard requires IP40, and the door gap is not greater than 1.0mm.

[0064] The door gap between the cabinet door and the frame column 12 is closed by the door gap closing edge strip 4, and the door gap of the cabinet door is controlled by the cabinet door and the door gap closing edge strip 4. The cabinet door gap of the switch cabinet in this industry no longer needs to be guaranteed by the bending process of the cabinet door to meet the standard. Through trial production, this solution can effectively make the door gap less than 1.0mm to meet the standard.

[0065] The cost of installing glass doors on the front and back of the cabinet is about 1,000 yuan / unit. A 2150mm door gap sealing strip 4 only costs 30 yuan. The door hinge side of the cabinet frame is arranged with one strip on the front and one on the back, that is, two door gap sealing strips 4, with an application cost of 60 yuan. A 30-meter adhesive sealing strip is used on the three sides of the cabinet door, with a cost of only 60 yuan. With low application cost, the overall cabinet door gap can be less than 1.0, meeting the IP40 protection level. Moreover, the solution of the utility model is quick to install and has practical feasibility.

[0066] The utility model can also be applied to the unit door 7 located in front of the cabinet of the drawer-type unit and the fixed partition-type unit; the utility model can be applied not only to the cabinet door of the low-voltage switch cabinet, but also to the sealing of the side door gap of the cabinet door of the high-voltage switch cabinet.

[0067] The technical solution of the utility model can be applied to various cabinet doors, so that the protection level of the cabinet doors is higher than the standard IP40 and meets the requirement of a door gap of 1.0 mm.

[0068] For user locations with high requirements for preventing dust, humidity and polluted gases from entering the cabinet, it is only necessary to further add adhesive sealing strips to the other three sides of the cabinet door for sealing. There is no need to add adhesive sealing strips to the hinge fixed side of the door where it is difficult to glue sealing strips, which greatly reduces the requirements for the dust, humidity and polluted gas door gap sealing structure process.

[0069] Example 2

[0070] like Fig.18 As shown, a switch cabinet frame uses a side strip to close the door gap and a combined hinge fixing structure. Similar to Example 1, the switch cabinet of this embodiment is also specifically a low-voltage switch cabinet, and the cabinet door is also specifically a cabinet rear door 6. The difference is that a door gap closing side strip 4 is only provided on the door hinge fixing side of the cabinet rear door 6.

This embodiment 3 is basically the same as the embodiment 1, the difference is that: the unit door 7 is installed on the unit side plate 8 of the drawer-type unit through the door hinge. Specifically, on the front curved edge of the unit side plate 8 of the drawer-type unit, as shown in FIG. Fig.19 shown.

[0073] The door gap closing strips 4 on the door lock side and the door hinge fixing side are directly fixed to the frame columns 12 on both sides of the unit door 7 by fixing screws 13.

[0074] The fixed section 1 - 1 of the support hinge 1 is located on the side of the extended section 1 - 2 facing the cabinet door, and the fixed section 1 - 1 is fixed to the unit side plate 8 of the drawer-type unit by means of fixing screws 13 .

[0075] The top of the curved edge of the support hinge 1 and the unit door 7 is provided with a notch to avoid blocking, so as to ensure that the door can be opened and closed 180 degrees effectively without blocking. Through the components installed on the unit door 7, such as the handle and the transition hole blocking member 16, the door opening angle is controlled to 155 degrees to prevent the door from being opened too far and colliding with the rear door 6 of another switch cabinet, causing damage to the surface.

[0076] A loop matching mark 17 is provided on the panel 4 - 2 of the door gap closing edge strip 4 on the door lock side.

[0077] like Fig.21 As shown, the specific structure of the inner edge 4-2-1 of the panel 4-2 of the door gap closing strip 4 on the door hinge fixing side and the door lock side cooperating with the cabinet door is: the inner edge 4-2-1 of the panel 4-2 of the door gap closing strip 4 extends to the side of the cabinet door and cooperates with the side gap of the cabinet door to prevent the door gap closing strip 4 from interfering with the plugging and unplugging operation of the drawer-type unit.
