Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: a model for a rubber elbow comprises a model body 1, wherein the model body 1 comprises a first bent rod 101, a second bent rod 102, a third bent rod 103 and a fourth bent rod 104, a first damping rotating shaft 1011 is arranged at the end part of the first bent rod 101, the first damping rotating shaft 1011 is rotatably connected with the end part of the third bent rod 103, the third bent rod 103 can rotate around the first damping rotating shaft 1011, and forms the required bending degree of the rubber bent pipe with the first bent rod 101, the end part of the second bent rod 102 is provided with a second damping rotating shaft 1021, so that the fourth bent rod 104 can rotate around a damping rotating shaft 1011, the bending degree required by the rubber bent pipe is formed by the damping rotating shaft II 1021 and the bent rod II 102, the damping rotating shaft II 1021 is rotatably connected with the end part of the bent rod II 104, the cross section of the bottom end of the bent rod III 103 is provided with the integrally formed bolt 2 and the limiting pin 3, and the cross section of the top end of the bent rod II 104 is provided with the jack 4 and the limiting hole 5, so that the bent rod III 103 and the bent rod II 104 can be conveniently connected and detached.

Specifically, as shown in fig. 2, the model body 1 is made of stainless steel, which is beneficial to shaping the rubber elbow, and has higher hardness, which is beneficial to prolonging the service life of the model body 1.

Specifically, as shown in fig. 2, the plug 2 is in plug connection with the jack 4, so that the plug 2 cannot rotate around the plug when the third curved bar 103 is connected with the fourth curved bar 104.

Specifically, as shown in fig. 2, the limiting pin 3 is in plug-in connection with the limiting hole 5, so that the third bending rod 103 and the fourth bending rod 104 can be conveniently detached, and the rubber bent pipe can be easily separated from the model body 1.
