Detailed Description

The following are specific embodiments of the present invention and are further described with reference to the drawings, but the present invention is not limited to these embodiments.

Example one

As shown in fig. 1 and fig. 2, this swift formula body coupling connection structure, including body 1 and joint, the hoop 2 is cup jointed to the socket periphery of body 1, hoop 2 is the smooth complete elasticity ring body of round, and the joint has grafting end 3, and grafting end 3 periphery sets up two rings of barbs 4 at most, and the length of grafting end 3 is less than the length of hoop 2, and grafting end 3 stretches into in the socket of body 1, makes barb 4 and the inner wall of body 1 form the joint through the frictional force locking under the constraint of hoop 2.

Among this swift formula body joint connection structure, do the test through simulation analysis and 3D printing, confirm the suitable external diameter of barb 4, connect and can design into 2 barb 4 structures, save material cost and part space more than 3 barb 4 structures. By setting the length of the hoop 2 to be larger than that of the joint plug-in end 3, the hoop 2 completely covers the outer edge of the back-off part of the plug-in end 3, so that the connection strength is enhanced.
