Description

Technical Field

[0001] This application relates to the technical field of electrical equipment, and in particular to a through-wall bushing. Background Technology

[0002] Through-wall bushings are widely used in power switchgear of power supply systems, serving as a connection transition and insulation isolation for high-voltage power supply lines passing through the switchgear.

[0003] In related technologies, the through-wall bushing includes a mounting plate, a bushing, and bolts. Mounting holes are opened on the mounting pipe, and connecting holes that communicate with the mounting holes are opened on the side plate of the electrical cabinet. Bolts pass through the mounting holes and connecting holes in sequence, and then the bolts are screwed in place by nuts.

[0004] Regarding the aforementioned technologies, the inventors believe that installing through-wall sleeves requires manually guiding the sleeve to align the mounting hole with the connection hole, which is inconvenient. Utility Model Content

[0005] To facilitate the installation of wall bushings, this application provides a wall bushing.

[0006] The wall sleeve provided in this application adopts the following technical solution:

[0007] A through-wall sleeve includes an insulating tube, a mounting plate, a screw, a nut, and an installation component. The mounting plate is installed on the outer periphery of the insulating tube, and a through hole is provided on the mounting plate for the screw to pass through. The nut is threaded onto the screw. The installation component includes a sleeve, connecting strips, and a buckle. The sleeve is coaxially disposed in the through hole. Multiple connecting strips are provided and spaced apart circumferentially along the axis of the sleeve. The buckle is disposed on the side of the connecting strip away from the sleeve.

[0008] With the above technical solution, when it is necessary to install a through-wall sleeve, the sleeve can be inserted into the through hole, and then the pupil on the mounting plate can be aligned with the connection hole of the wall panel so that the connecting strip is inserted into the connection hole. When the connecting strip is fully inserted into the connection hole, the buckle is snapped onto the side wall of the wall panel. At this time, the bolt can be aligned with the sleeve and inserted, and then the nut can be connected to the bolt to facilitate the installation of the through-wall sleeve.

[0009] Optionally, a limit ring is provided at the end of the sleeve away from the connecting strip.

[0010] With the above technical solution, the sleeve is inserted into the through hole, and the limiting ring limits the sleeve, reducing the risk of the sleeve sliding directly out of the connection hole.

[0011] Optionally, a notch is provided at the connection between the connecting strip and the sleeve.

[0012] The above technical solution, by setting a notch, makes the connection between the connecting strip and the sleeve flexible, so that the connecting strip will not interfere when inserted into the connecting hole, which facilitates the installation.

[0013] Optionally, the cut is V-shaped, and the opening of the cut is oriented toward the side away from the axis of the sleeve.

[0014] With the above technical solution, the connecting strip is flipped inward along the connection point of the cut into the sleeve axis, and then the bolt is inserted into the sleeve. The bolt pushes the connecting strip outward, so that the connecting strip abuts against the wall of the connecting hole. At this time, the buckle can be engaged with the side wall of the wall panel.

[0015] The beneficial effects of this utility model are as follows: When it is necessary to install a through-wall sleeve, the sleeve can be inserted into the through hole, and then the pupil on the mounting plate can be aligned with the connection hole of the wall panel so that the connecting strip is inserted into the connection hole. When the connecting strip is fully inserted into the connection hole, the buckle is snapped onto the side wall of the wall panel. At this time, the bolt can be aligned with the sleeve and inserted, and then the nut can be connected to the bolt, which facilitates the installation of the through-wall sleeve.

[0020] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0021] This application discloses a through-wall sleeve.

[0022] Reference Figure 1 , Figure 2 and Figure 3The through-wall sleeve 51 includes an insulating tube 1, a mounting plate 2, a screw 3, a nut 4, and a mounting component 5. The mounting plate 2 is installed on the outer periphery of the insulating tube 1. The mounting plate 2 has a through hole 21 for the screw 3 to pass through. The nut 4 is threaded onto the screw 3. The mounting component 5 includes a sleeve 51, a connecting strip 52, and a buckle 53. The sleeve 51 is coaxially arranged in the through hole 21. Multiple connecting strips 52 are provided. The connecting strips 52 are spaced apart circumferentially along the axis of the sleeve 51. The buckle 53 is located on the side of the connecting strip 52 away from the sleeve 51.

[0023] When it is necessary to install the through-wall sleeve 51, the sleeve 51 can be inserted into the through hole 21, and then the pupil on the mounting plate 2 can be aligned with the connection hole of the wall panel so that the connecting strip 52 can be inserted into the connection hole. When the connecting strip 52 is fully inserted into the connection hole, the buckle 53 is snapped onto the side wall of the wall panel. At this time, the bolt can be aligned with the sleeve 51 and inserted, and then the nut 4 can be connected to the bolt to facilitate the installation of the through-wall sleeve 51.

[0024] Reference Figure 3 A limit ring 511 is provided at the end of the sleeve 51 away from the connecting bar 52.

[0025] The sleeve 51 is inserted into the through hole 21, and the limiting ring 511 limits the sleeve 51 to reduce the risk of the sleeve 51 sliding directly out of the connection hole.

[0026] Reference Figure 3 A notch 521 is provided at the connection between the connecting strip 52 and the sleeve 51.

[0027] By setting the notch 521, a flexible connection is made between the connecting strip 52 and the sleeve 51, so that the connecting strip 52 will not interfere when inserted into the connecting hole, which facilitates installation.

[0028] Reference Figure 3 The cut 521 is V-shaped, and the opening of the cut 521 is set to the side away from the axis of the sleeve 51.

[0029] The connecting strip 52 is flipped inward along the connection point of the cut 521 into the axis of the sleeve 51. Then the bolt is inserted into the sleeve 51 and the bolt pushes the connecting strip 52 outward, so that the connecting strip 52 abuts against the wall of the connecting hole. At this time, the buckle 53 can be snapped into the side wall of the wall panel.

[0030] The implementation principle of a through-wall sleeve 51 in this application embodiment is as follows: When it is necessary to install the through-wall sleeve 51, the sleeve 51 can be inserted into the through hole 21, and then the pupil on the mounting plate 2 is aligned with the connection hole of the wall panel so that the connecting strip 52 is inserted into the connection hole. When the connecting strip 52 is fully inserted into the connection hole, the buckle 53 is snapped onto the side wall of the wall panel. At this time, the bolt can be aligned with the sleeve 51 and inserted, and then the nut 4 is connected to the bolt to facilitate the installation of the through-wall sleeve 51.

[0031] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
