Detailed Description

In order to facilitate understanding of those skilled in the art, the present invention will be further described with reference to the following examples and drawings, which are not intended to limit the present invention. The present invention will be described in detail with reference to the accompanying drawings.

Example one

As shown in fig. 1 to 3, a high-strength impact-resistant composite sleeve, including being responsible for 1, be responsible for 1 and include body 2 and the cover establish a plurality of boss 3 in body 2 periphery, boss 3 arranges along the axial of body 2 in proper order, and boss 3's cross section is the rectangle, and the sunken recess 4 that is formed with in boss 3's corner.

The groove wall of the groove 4 at the corner of the reinforcing block 3 is equivalent to the corner reinforcing rib of the reinforcing block 3, so that the compression resistance of the corner of the reinforcing block 3 can be improved; simultaneously, set up the span that 3 edges and corners of recess 4 can reduce the boss to reach the effect that improves 3 edges and corners compressive capacity of boss, and prevent that the edge of boss 3 from breaking, and then improve the utility model discloses an impact resistance.

As shown in fig. 1, the cross-section of the tube body 2 is circular, so that the tube body 2 is easy to manufacture. At the same time, the tubular body 2, which is circular in cross section, has a greater flux and less fluid resistance to the inside of the tube.

As shown in fig. 1 and 3, in the present embodiment, the corners of the reinforcing block 3 are provided with rounded corners 31, so as to prevent the corners of the reinforcing block 3 from scratching a user. Meanwhile, in this embodiment, when a plurality of sleeves are used, the plurality of sleeves may be distributed in a matrix, and the rounded corners 31 of the respective sleeves may be joined together to form a through groove, which may be used by a user to route wires.

Example two

As shown in fig. 4 and 5, the high-strength impact-resistant composite bushing further includes a straight inner pipe 5 disposed inside the main pipe 1, and the straight inner pipe 5 is connected to the inner wall of the pipe body 2. The utility model has double-layer walls through the straight inner pipe 5, thereby further improving the compression resistance of the utility model; meanwhile, the straight inner pipe 5 can smooth the inner wall of the cable protection pipe, and when the cable protection pipe is used as a cable protection pipe, the cable protection pipe can be conveniently threaded by a user; and when will the utility model discloses when being used as the blow off pipe, the smooth inner wall can reduce the resistance of sleeve pipe to sewage.
