Embodiment 1

[0047] like Figure 1 to Figure 3As shown, a high-strength impact-resistant composite casing includes a main pipe 1, the main pipe 1 includes a pipe body 2 and a plurality of reinforcement blocks 3 sleeved on the outer periphery of the pipe body 2, and the reinforcement blocks 3 are sequentially arranged along the axial direction of the pipe body 2. Arranged, the cross section of the reinforcing block 3 is rectangular, and the corners of the reinforcing block 3 are recessed to form grooves 4 .

[0048] The groove wall of the groove 4 at the corner of the reinforcement block 3 is equivalent to the corner reinforcement rib of the reinforcement block 3, which can improve the compressive performance at the corner of the reinforcement block 3; at the same time, setting the groove 4 can reduce the strength of the reinforcement block 3 corners. In order to achieve the effect of improving the compressive capacity of the corners of the reinforcement block 3, and prevent the corners of ...

Embodiment 2

[0052] like Figure 4 and Figure 5 As shown, the high-strength impact-resistant composite casing also includes a straight inner tube 5 arranged inside the main pipe 1 , and the straight inner tube 5 is connected to the inner wall of the tube body 2 . The present invention has a double wall through the straight inner tube 5, which further improves the compression resistance of the present invention; at the same time, the straight inner tube 5 can make the inner wall of the present invention smooth, and when the present invention is used as a cable protection tube, it can facilitate The user threads; and when the present invention is used as a sewage pipe, the smooth inner wall can reduce the resistance of the casing to sewage.

[0053] like Figure 5 As shown, one end of the straight inner pipe 5 is provided with a connecting pipe 6 protruding from the main pipe 1, and the outer periphery of the connecting pipe 6 is provided with corrugations 61, and the cross section of the...

Embodiment 3

[0055] like Image 6 and Figure 7 As shown, in this embodiment, the high-strength impact-resistant composite sleeve also includes a straight outer tube 7, the main pipe 1 is arranged inside the straight outer tube 7, and all reinforcing blocks 3 are connected to the straight outer tube 7. inner wall connections. When the present invention is used, the groove 4 and the space between the two reinforcing blocks 3 are easy to hide dirt and dirt, making it inconvenient for users to clean. In the present invention, a straight outer tube 7 is arranged outside the main pipe 1, so that the user is easy to clean.

Abstract

The invention relates to the technical field of sleeves, in particular to a high-strength impact-resistant composite sleeve. The high-strength impact-resistant composite sleeve comprises a main pipe,wherein the main pipe comprises a pipe body and a plurality of reinforcing blocks arranged on the periphery of the pipe body in a sleeved mode, the reinforcing blocks are arranged in sequence along the axial direction of the pipe body, the cross section of each reinforcing block is rectangular, and grooves are formed in the corners of the reinforcing blocks. According to the high-strength impact-resistant composite sleeve, the grooves are formed in the corners of the reinforcing blocks so as to improve the compression resistance of the corners of the reinforcing blocks, so that the fracture condition of the sleeve is reduced, and the impact resistance of the sleeve is further improved.

Description

technical field [0001] The invention relates to the technical field of bushings, in particular to a high-strength impact-resistant composite bushing. Background technique [0002] In order to increase the compressive performance of the casing, many manufacturers will set a plurality of rectangular reinforcing blocks on the outer periphery of the casing to enhance the compressive performance of the casing. However, during use, the corners of the reinforcing block are often broken due to the uneven force on the two adjacent sides, resulting in insufficient impact resistance of the casing. Contents of the invention [0003] In order to overcome the shortcomings and deficiencies in the prior art, the object of the present invention is to provide a high-strength impact-resistant composite sleeve. [0004] The purpose of the present invention is achieved through the following technical solutions: a high-strength impact-resistant composite casing, including a main pipe, the main...
