The patent number is "CN218472712U", and the patent name is "A utility model patent for an electric wall bushing", which includes a mounting seat, insulating sleeves are connected to both sides of the mounting seat, a copper bar is connected to the wall bushing, and two end caps are fixed to the copper bar, and the two end caps are respectively set against one end of the two insulating sleeves, and also includes a sealing assembly arranged between the end cap and the mounting seat for sealing the wall bushing, and the sealing assembly includes a fixing rod fixed to the end cap, and a sleeve is slidably connected to the outside of the fixing rod.

[0003] However, the above-mentioned wall bushing still has certain disadvantages in certain usage situations: the insulating sleeve of the above-mentioned wall bushing is tightly against the inner wall of the annular groove, forming a sealing effect between the insulating sleeve and the end cover. However, the pulling component is arranged on the outside of the insulating sleeve. In a wider wall, the wall contacts the fixed rod but not the insulating sleeve, which will affect the overall installation of the insulating sleeve and the stability is poor. Therefore, a wall bushing for power engineering construction is proposed to solve the above-mentioned defects. On the other hand, the mounting seat in the above-mentioned wall bushing is movably connected to the insulating towers on both sides, which is more troublesome during assembly, and this connection method cannot guarantee the sealing of the connection between the mounting seat and the insulating sleeves on both sides. Summary of the invention

[0004] The utility model overcomes the shortcomings of the prior art and provides a wall bushing for electric power engineering construction.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a wall bushing for power engineering construction, comprising: a copper busbar arranged in an insulating sleeve, two annular protrusions are integrally arranged on the outer peripheral side of the middle part of the insulating sleeve, a card groove is formed between the two annular protrusions, two fixing plates are arranged in the card groove, and sealing components are arranged at both ends of the insulating sleeve, and the sealing components include: a connecting plate integrally arranged inside the insulating sleeve and an assembly plate movably arranged at both ends of the insulating sleeve, the assembly plate is threadedly connected to the connecting plate through a plurality of locking rods, and the copper busbar is arranged through the connecting plate and the assembly plate.

[0006] In a preferred embodiment of the utility model, an elastic component is arranged at one end of the locking rod, and the elastic component comprises: two annular gaskets sleeved on the locking rod, and the two annular gaskets are connected by a supporting spring.

[0007] In a preferred embodiment of the utility model, the inner circumferential side surfaces of both ends of the insulating sleeve are configured as conical surfaces, one end of the assembly plate is configured as a cone, and the insulating sleeve and the assembly plate are butted against each other.

[0008] In a preferred embodiment of the utility model, a protective tube is integrally arranged on one side of the assembly plate, and a notch is arranged at the lower part of the protective tube.

[0009] In a preferred embodiment of the utility model, the two fixing plates are connected into one body by bolt rods, and the fixing plates are connected to the wall panels.

[0010] In a preferred embodiment of the utility model, a plurality of insulating protrusions are arranged in an array on the outer peripheral side surface of the insulating sleeve, and the insulating protrusions are integrally formed with the insulating sleeve.

[0011] In a preferred embodiment of the present invention, a slot is provided at the end of the locking rod.

[0012] The utility model solves the defects existing in the background technology, and has the following beneficial effects:

[0013] (1) The utility model uses a locking rod to thread the connecting plate. During the screwing process of the locking rod, the annular gasket continuously squeezes the assembly plate, so that one end of the assembly plate is tightly connected to the end of the insulating sleeve, sealing the inside of the insulating sleeve. In addition, the locking rod is set on the inside of the insulating sleeve, which will not affect the overall installation of the insulating sleeve. In a wider wall, the insulating protrusions on the outer peripheral side of the insulating sleeve directly contact the wall to bear the force, and the insulating sleeve has a better fixing effect and better practicality. On the other hand, the inner peripheral side surfaces of the two ends of the insulating sleeve are set as conical surfaces, and one end of the assembly plate is set as a cone, which can further increase the bonding strength between the insulating sleeve and the assembly plate and improve the sealing effect.

That is, the insulating sleeves on both sides of the assembly plate are formed in one piece, thereby ensuring the stability and sealing of the overall structure of the wall sleeve.

DETAILED DESCRIPTION

[0020] The present invention will now be further described in detail in conjunction with the accompanying drawings and embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0021] like Figure 1 and Figure 2 As shown, a wall bushing for electric power engineering construction includes: a copper busbar 2 arranged in an insulating sleeve 1, two annular protrusions 3 are integrally arranged on the outer peripheral side of the middle part of the insulating sleeve 1, a slot 4 is formed between the two annular protrusions 3, two fixing plates 5 are arranged in the slot 4, and the fixing plates 5 are connected to the wallboard. The two fixing plates 5 cooperate with the slot 4 and are then connected into one by bolt rods, so that the insulating sleeve 1 and the wall can be fixedly connected, that is, the insulating sleeve 1 on both sides of the assembly plate 7 are integrally formed, thereby ensuring the stability and sealing of the overall structure of the wall bushing. On the other hand, a protective tube 12 is integrally arranged on one side of the assembly plate 7, and a notch is arranged at the lower part of the protective tube 12. The protective tube 12 can protect the two ends of the copper busbar 2 and prevent direct erosion by rainwater.
