Detailed Description

The present invention will be described in further detail with reference to specific examples.

Example (b):

as shown in fig. 1 to 3, the utility model discloses a high accuracy high strength carbon fiber thin wall side's pipe bearing diagonal additional strengthening, including crossing the vertical pipe 1a of connecting and violently managing 1b and draw the reinforcement subassembly 2 in the corner of vertical pipe 1a and violently managing 1b to one side, all open the mounting hole 11 that is used for fixing rivet nut 4 on vertical pipe 1a and violently managing 1b, reinforcement subassembly 2 includes reinforcement pipe 21, be fixed in the connecting ball 22 at reinforcement pipe 21 both ends and pass the connecting pin 23 of connecting ball 22 centre of sphere, connecting pin 23 is perpendicular to vertical pipe 1a and violently manages 1b simultaneously, the side of connecting pin 23 is equipped with screw fixation hole 231, the tight screw 24 and the rivet nut 4 fixed connection who passes screw fixation hole 231. The longitudinal pipes 1a and the transverse pipes 1b are made of carbon fiber materials, and the strength of the materials is reduced by punching the mounting holes 11, so that the connecting strength of the pull rivet nut 4 needs to be ensured. During installation, the connecting ball 22 on one side is fixed with one end of the reinforcing pipe 21, the connecting pin 23 is inserted, then the connecting pin 23 is fixed on the rivet nut 4 on the longitudinal pipe 1a by the fastening screw 24 in a loosening way, and at the moment, the reinforcing pipe 21 can still swing around the axis of the connecting pin 23; the connecting ball 22 at the other end is close to the blind rivet nut 4 on the transverse tube 1b, and is also penetrated by another connecting pin 23, and then is fixed on the blind rivet nut 4 of the transverse tube 1b by a fastening screw 23, and finally, two fastening screws 24 are locked, so that the connection can be completed. This structure is connected vertical pipe 1a and violently pipe 1b through the reinforcement pipe 21 that draws to one side, and connection ball 22 can adapt to fixed angle in a flexible way, and the location is accurate, and is fixed stable, has very high flexibility moreover. Since the connecting pin 23 allows the connecting ball 22 to rotate within a certain angle, the longitudinal pipe 1a and the transverse pipe 1b are not necessarily connected vertically as shown in the figure, and may have an acute angle.

As shown in fig. 2, the connecting ball 22 includes a frustum portion having a center of sphere on an axis of the frustum portion and a spherical portion having a pin hole for inserting a connecting pin, the frustum portion being fixed to an end surface of the reinforcing pipe.

As shown in fig. 2 to 4, a washer 3 is provided between the connecting ball 22 and the blind rivet nut 4, and a countersunk hole 31 is provided in the middle of the washer 3 to avoid the outer end of the blind rivet nut 4. The gasket 3 has a fixed position relation with the blind rivet nut 4 by using the countersunk hole 31, and meanwhile, the gasket 3 enables the connecting ball 22 to be better fixed on the longitudinal pipe 1a or the transverse pipe 1b, so that the structure is more stable.

As shown in fig. 3 and 4, the counter bore 31 has a concave spherical surface 32 matching the outer shape of the connecting ball 22 on the side facing the connecting ball 22. The concave spherical surface 32 enables the center of the connecting ball 22 to fall on the axis of the counter sink 31 when the set screw 24 is tightened, thereby further improving the connection accuracy.

As shown in fig. 3, one end of the screw fixing hole 231 is provided with a countersunk surface 232 for contact with the nut of the fastening screw 24. When the set screw 24 is tightened, the nut comes into surface contact with the countersunk surface 232, and the center of the connecting ball 22 is located on the axis of the set screw 24.

What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
