Further optimizing the technical scheme, the adjacent butterfly-shaped sleeves are mutually and closely connected.
Further optimizing the technical scheme, the inner wall of the butterfly sleeve is coated with a smooth coating.
Compared with the prior art, the utility model has the following advantages: through the structure with electrician's sleeve pipe design for inner tube and outer tube, fixed point rotation is provided with at least one elastic bead on the outer tube to elastic bead and the outer wall looks butt of inner tube. In addition, the inside of inner tube still is equipped with butterfly sleeve pipe, and butterfly sleeve pipe's both ends contact with the inner wall of inner tube. When the electrician sleeve is impacted by the outside, the elastic function of the elastic beads can absorb a part of impact force, meanwhile, the butterfly sleeve is contacted with the inner wall of the inner tube, the impact of the rest part can be blocked, and the damage to cables inside the butterfly sleeve is avoided. Moreover, because the elastic beads can rotate at fixed points, the electric bushing is convenient to install through the wall.

It should be understood that the description is only illustrative and is not intended to limit the scope of the utility model. In addition, in the following description, descriptions of well-known structures and techniques are omitted so as not to unnecessarily obscure the present utility model.
An impact-resistant electrical bushing, the electrical bushing comprising:
an outer tube 1;
at least one elastic bead 2, wherein the elastic bead 2 is arranged on the outer wall of the outer tube 1, and the elastic bead 2 can rotate on the outer wall of the outer tube 1 at fixed points;
an inner tube 3, wherein the inner tube 3 is arranged inside the outer tube 1, and the outer wall of the inner tube 3 is abutted against the elastic beads 2;
at least one butterfly sleeve 4, butterfly sleeve 4 set up in the inside of inner tube 3, every butterfly sleeve 4's both ends all with the inner wall of inner tube 3 contacts.
Further optimizing this technical scheme, the material of elastic bead 2 is elastic plastic.
Further optimizing this technical scheme, the elastic bead 2 along circumference and radial direction equidistance of outer tube 1 distribute on the outer wall of outer tube 1.
Further optimizing the technical scheme, the adjacent butterfly-shaped sleeves 4 are mutually and closely connected.
Further optimizing the technical scheme, the inner wall of the butterfly sleeve 4 is coated with a smooth coating.
The embodiment of the disclosure provides an impact-resistant electrical bushing, which is shown in fig. 1 and 2, and comprises an outer tube 1, an inner tube 3, elastic beads 2 and a butterfly bushing 4, wherein the inner tube 3 is arranged inside the outer tube 1, the elastic beads 2 are rotatably arranged on the outer wall of the outer tube 1, the elastic beads 2 can rotate on the outer wall of the outer tube 1 at fixed points, and a part of the elastic beads 2 are also abutted against the outer wall of the inner tube 3. The inside of the inner tube 3 is provided with a butterfly sleeve 4, and the butterfly sleeve 4 is provided with a plurality of along the axial of the inner tube 3, and the both ends of every butterfly sleeve 4 all contact with the inner wall of the inner tube 3, and in addition, the inside of butterfly sleeve 4 is provided with the cable etc. that are used for the protection.
