Description

Technical Field

[0001] The utility model relates to the technical field of switch cabinets, and in particular to a side plate threading structure of a switch cabinet. Background Art

[0002] The switch cabinet is an important equipment used in the power supply and distribution system, and is a major component in the power transmission and distribution industry. The switch cabinet generally includes a cabinet body, primary and secondary components and secondary lines arranged in the cabinet body, and the side panels of the cabinet body are often provided with multiple threading holes for the input or output of the secondary lines. Traditionally, the threading holes on the side panels are generally arranged at intervals, and are all formed by knocking off the knock-off pieces. When in use, the number of knock-off pieces to be knocked off is selected according to the number of secondary lines. However, the above-mentioned setting, when there are many secondary lines, often makes the secondary lines more scattered and the wiring messy, which seriously affects the safety and reliability of the switch cabinet.

[0003] The related research on the switch cabinet threading structure in the prior art, such as the patent application CN 210779622 U, a knock-out hole structure for secondary line expansion, etc., can be achieved by continuously setting multiple knock-out pieces. After the multiple knock-out pieces are knocked out in sequence, a continuous threading hole for the secondary line to be threaded is formed. When there are many secondary lines, their distribution can be relatively concentrated to a certain extent, so that they can be bundled into piles, meeting the safety requirements of large-scale incoming and outgoing lines and improving the safety and reliability of the switch cabinet.

[0004] However, the continuous threading holes for secondary wires in the prior art are large holes. The presence of such large holes often leads to poor waterproof, dustproof and insect-proof effects of the switch cabinet. At the same time, the prior art is generally applicable to the side panels of the switch cabinet, resulting in general practicality as a whole. For example, once the cabinet is temporarily replaced on site, such as adjusting the middle cabinet to a side cabinet, the presence of such large holes on the side panel greatly affects the aesthetics. In addition, most of the prior art requires tedious and time-consuming knocking-off operations when threading. For example, when there are fewer secondary wires, at least one knock-off piece needs to be knocked off, and when there are more secondary wires, multiple knock-off pieces need to be knocked off, which can easily affect the threading efficiency of the switch cabinet.

[0005] Therefore, a new technical solution is needed to solve the above technical problems. Utility Model Content

[0006] The purpose of the utility model is to provide a switch cabinet side panel threading structure to solve the technical problem that the prior art proposed in the above background technology has general applicability to the switch cabinet side panel, resulting in general overall practicality, and not only affects the waterproof, dustproof and insect-proof effects of the switch cabinet, but also affects the threading efficiency of the switch cabinet.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A switch cabinet side panel threading structure, including a side panel, wherein the side panel is provided with a knock-out piece I that can be knocked off to form a threading hole I, the knock-out piece I is a rectangular knock-out piece and a plurality of threading holes II are spaced apart on the knock-out piece I, the threading holes II are all circular through holes, and the threading holes II are also provided with annular rubber sealing rings that are matched one by one, and the interior of each of the rubber sealing rings is separated to form a plurality of mutually independent threading grooves, and the side panel is also uniformly provided with knock-out pieces II on the outer periphery of the knock-out piece I that can be knocked off to form screw fixing holes for a closing plate that blocks the threading hole I, and the knock-out pieces II are all circular knock-out pieces.

[0009] Furthermore, the threading holes II are evenly distributed in a straight line on the knock-out piece I, and the knock-out pieces II are respectively located at the outer four corners of the knock-out piece I. Knock-out gaps are respectively formed between the knock-out piece I and the threading holes I, and between the knock-out piece II and the corresponding screw fixing holes. The knock-out gaps are linear and have a width not exceeding 0.05 mm. Each of the knock-out gaps is provided with a plurality of connecting ribs, and the length of the connecting ribs in the same knock-out gap is matched with the width of the knock-out gap.

[0010] Furthermore, the shape of the inner wall of the threading hole I matches the shape of the edge of the knock-off piece I, the shape of the inner wall of the screw fixing hole matches the shape of the corresponding edge of the knock-off piece II, and the length of the connecting rib is 1 mm.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. In the utility model, a knock-off piece I that can be knocked off to form a threading hole I is arranged on the side panel, and a plurality of threading holes II are arranged at intervals on the knock-off piece I, which effectively avoids tedious and time-consuming knock-off operations. That is, when there are many secondary wires, only one knock-off operation is required for the knock-off piece I, and the secondary wire passes through the threading hole I at this time. When there are fewer secondary wires, there is no need to perform a knock-off operation, and the secondary wire can be directly passed through the threading hole II. This greatly improves the threading efficiency of the switch cabinet. On this basis, the side plate is also evenly distributed on the outer periphery of the knock-off piece I The knock-out piece II is knocked off to form the screw fixing hole of the closing plate that blocks the wire threading hole I, so that after the knock-out piece I is knocked off to form the wire threading hole I, the screw fixing hole can be formed by knocking off the knock-out piece II, thereby facilitating the screw fixing of the closing plate that blocks the wire threading hole I. This blocks the wire threading hole I, thereby greatly improving the waterproof, dustproof and insect-proof effects of the switch cabinet, and effectively solves the unsightly problem caused by the exposure of the wire threading hole I on the side panel when the switch cabinet is used as a side cabinet, thereby making it more suitable for use and ultimately greatly improving the overall practicality.

[0013] 2. The threading holes II in the utility model are matched with annular rubber sealing rings in a one-to-one manner. In the utility model, the threading holes II and the rubber sealing rings work together to protect the secondary wires passing through the threading holes II and seal the areas outside the secondary wires in the threading holes II, thereby further improving the waterproof, dustproof and insect-proof effects of the switch cabinet. On this basis, the interior of each rubber sealing ring is separated to form a plurality of independent threading grooves, which effectively avoids the mixing of lines and mutual influence when a small number of secondary wires are pierced, thereby further improving the overall practicality and further optimizing the sealing effect of the rubber sealing ring, thereby further ensuring the waterproof, dustproof and insect-proof effects of the switch cabinet.

[0014] 3. In the case where the knock-off piece I is not knocked off, that is, when there are fewer secondary wires, the utility model does not need to specially set up a closing plate. Compared with directly opening threading holes on the closing plate, opening screw fixing holes on the side plate, and then fixing the closing plate to the side plate with screws, the utility model effectively saves the time for installing and disassembling the closing plate, thereby further ensuring the overall practicality.
