Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electric cabinet manufacturing, in particular to a bolt connection device and an electric cabinet. Background Art
[0002] Electrical cabinets are common power grid equipment, mainly including cabinet bodies and cabinet doors. Electrical equipment is installed in the cabinet bodies. The cabinet bodies are generally made of steel structures such as square tubes, channel steels, and angle steels. Most of them are welded and cannot be disassembled. The middle part of the square tube and the steel section cannot be connected by bolts because there is no operating space. The nuts cannot be operated after the bolts are inserted into the square tube. Utility Model Content
[0003] In order to solve the problems existing in the prior art, the utility model provides a bolt connection device and an electrical cabinet.
[0004] The specific scheme of the utility model is as follows: a bolt connection device, including two parallel support bars, each support bar is provided with a long strip through hole, a connecting block is installed between the two support bars, a pin is provided on both sides of the middle part of the connecting block, the pin is inserted into the long strip through hole of the support bar on the corresponding side, the pin is slidably connected to the long strip through hole, and a threaded hole is provided in the middle part of the connecting block.
[0005] Preferably, the connection block is substantially in the shape of a cuboid, and both ends of the cuboid are provided with inclined surfaces.
[0006] Preferably, guide holes are provided on both sides of the connecting block corresponding to the threaded hole.
[0007] Preferably, a limiting portion is provided at the outer end of the pin shaft, and a size of the limiting portion is larger than a width of the elongated through hole.
[0008] The utility model also provides an electrical cabinet, comprising a cabinet frame, wherein the cabinet frame is formed by connecting a square tube and a steel section, and the middle part of the square tube is connected to the steel section through the above-mentioned bolt connection device and bolts.
[0009] Furthermore, the steel section is channel steel or angle steel.
[0010] Compared with the prior art, the beneficial effects of the utility model are as follows: the bolt connection device can be suitable for use in an environment where only one side of two connecting parts has an operating space; the bolt connection device is used to realize bolt connection between the middle part of the square tube of the electrical cabinet and other structural parts, instead of welding, so that it can be disassembled.

[0017] like Figure 1-5 As shown, this embodiment provides a bolt connection device, including two parallel support bars 1, each support bar 1 is provided with a long strip through hole 2, a connecting block 4 is installed between the two support bars 1, and a pin shaft 3 is provided on both sides of the middle part of the connecting block 4. The pin shaft 3 is inserted into the long strip through hole 2 of the support bar 1 on the corresponding side, the pin shaft 3 is slidably connected with the long strip through hole 2, and a threaded hole 5 is provided in the middle part of the connecting block 4.
[0018] Preferably, the connection block 4 is substantially in the shape of a cuboid, and both ends of the cuboid are provided with inclined surfaces 6; by providing the inclined surfaces 6, the connection block 4 can be easily pushed and turned over to enter a state ready for connection.
[0019] Preferably, guide holes are provided on both sides of the threaded hole 5 corresponding to the connecting block 4; by providing the guide holes, the bolt 7 can smoothly enter the threaded hole 5, so that the inner end of the bolt 7 can be lowered and docked with the threaded hole 5 in an invisible manner.
[0020] Preferably, a limiting portion is provided at the outer end of the pin shaft 3 , and the size of the limiting portion is larger than the width of the elongated through hole 2 .
[0021] This embodiment also provides an electrical cabinet, including a cabinet frame, which is formed by connecting a square tube and a steel section 9 , and the middle part of the square tube is connected to the steel section 9 through the above-mentioned bolt connection device and bolts 7 .
[0022] Furthermore, the steel section 9 is made of channel steel or angle steel.
[0023] When the utility model is used, the specific operation is as follows: first, the square tube 8 and the steel 9 to be connected are punched at the connection part, and the size of the hole is just enough to pass the utility model, then the square tube 8 and the steel 9 are stacked and the holes are aligned, and then a bolt connection device of the utility model is taken to Figure 1Insert the bolt 7 into the hole from the outside, leaving a section outside the hole and fixing it to prevent it from falling into the square tube 8, then take a bolt 7 and insert it into the hole, control the bolt 7 to push the connecting block 4 in the square tube 8, and flip the connecting block 4 about 90°. At this time, since the length of the connecting block 4 is greater than the diameter of the hole, it can be stuck on the inside of the hole of the square tube 8, and then connect the inner end of the bolt 7 with the threaded hole 5 of the connecting block 4. Finally, keep tightening the bolt 7, and the connecting block 4 will move along the long strip through hole 2 toward the head of the bolt 7 until the connecting block 4 and the bolt 7 lock the steel section 9 and the square tube 8. When disassembling, first loosen the bolt 7 and take it out, then push the connecting block 4 in the direction away, and then flip it at a certain angle so that the connecting block 4 can pass through the hole.
