The elastic rope 11 at the end of the tent pole 9 penetrates from one end of the rope through hole 8 of the positioning ball 7 and penetrates out from the other end to bind the positioning ball 7. The other two tent poles 9 share one elastic rope 11, when the elastic rope 11 is threaded through the two tent poles 9, one of the two tent poles 9 is threaded through the elastic rope 11 and then is threaded into the inner cavity of the inner support ring 2 together with the elastic rope 11 from the spare sleeve 3, the elastic rope 11 is threaded through one end of the rope threading hole 8 of the positioning ball 7 and is threaded out from the other end, and then is threaded out of the outer support ring 1 from the sleeve 3 in the inner cavity of the inner support ring 2, and at the moment, the other tent pole 9 is threaded.

The principle of the invention is as follows:

1. three sleeves 3 are fixed by means of an inner support ring 2 and an outer support ring 1. The figure enclosed by the inner and outer support rings between two adjacent sleeves 3 and the sleeves 3 is similar to a triangle (the distance between the two sleeves 3 and the side surface of the inner support ring 2 is shorter than an arc of about 1.5mm, which can be regarded as a vertex of the triangle, and the arc connection part between the sleeve 3 and the outer support ring 1 can be regarded as the other two vertices). Pour the epoxy layer on sleeve 3 and make the sleeve 3 that is located between 1 inboard of outer support ring and the 2 outsides of inner support ring by the firm kayser between two first, second joint holes to keep invariable length, make two length of sides of triangle-shaped keep invariable. The closed ring structure of the inner and outer support rings is not easy to deform, and the positions of the clamping holes distributed on the rings are unchanged, so that the included angle between any two sleeves 3 can be kept stable and unchanged. The connected structure of the three triangles enables the arc of the outer support ring 1 not to be easily deformed, so that the structure of the whole three-way connector is stable. Even if one of the circular arcs bears a large external force to generate slight expansion or compression deformation, the other two triangles are connected with the other circular arc to generate corresponding pushing force or pulling force so as to maintain the integrity of the whole structure. The reducing small holes are not formed in the sleeve 3, so that the tent poles 9 can directly penetrate through the sleeve to directly enter the inner cavity of the inner support ring 2, the space of the tent pole three-way connector is fully utilized, and the size of the whole tent pole three-way connector is small. The movable positioning ball 7 is arranged in the inner cavity of the inner supporting ring 2, so that the elastic rope 11 of the tent pole 9 can conveniently pass through the rope through hole 8 on the positioning ball 7 and easily finish rope binding.

2. The elastic ropes 11 of the three tent poles 9 are connected together by the positioning balls 7, the tent poles 9 are pulled into the sleeve 3 under the elastic action of the elastic ropes 11 and extrude the positioning balls 7 from three different directions, the positioning balls 7 are fixed in the inner cavity of the inner support ring 2 by the elastic ropes 11 of the three tent poles 9, the three tent poles 9 share the same plane, and the positioning balls 7 cannot leave the plane even if being extruded, so that the tail ends of the three tent poles 9 keep a relatively fixed distance in the inner cavity of the inner support ring 2, the length of the tent poles 9 entering the inner cavity of the inner support ring 2 is limited, and the phenomenon that the tent poles 9 are damaged or the tent structure is unstable due to the fact that one of the tent poles 9 enters the inner cavity of the inner support ring 2 due to the fact that the length of the one of the tent poles 9 is too large and the lengths of the other two tent poles 9 are not enough is avoided. The positioning balls are applied, so that the three tent rods 9 are not directly contacted with each other, and local abrasion caused by point-shaped or linear friction due to intersection of plane included angles of the tail ends of the three tent rods 9 is avoided. The plane at the tail end of the tent pole 9 is tangent to the spherical surface of the positioning ball 7, the included angle of the contact surface is smaller, the friction between the tent pole 9 and the positioning ball 7 is smaller under the action of the elastic rope 11, and therefore the positioning ball 7 also plays a role in reducing the friction to protect the tent pole 9.

3. On the premise of ensuring the integrity and the stress strength of the annular structures of the inner and outer support rings, the hollow patterns on the inner and outer support rings can reduce the material consumption and reduce the weight to the maximum extent.

4. The sleeve 3 is made of hard metal such as stainless steel and the like, has strong rigidity, and can still keep large stress strength under the condition of thinner material. The inner and outer support rings made of carbon fiber provide a support structure for the sleeve 3, the annular inner and outer support rings can conduct external force acting on a certain sleeve 3 to another sleeve 3, and the sleeve 3 can conduct stress to the tent rod 9.

The above-mentioned specific implementation is the preferred embodiment of the present invention, can not be right the utility model discloses the limit, any other does not deviate from the technical scheme of the utility model and the change or other equivalent replacement modes of doing all contain within the scope of protection of the utility model.
