Detailed Description

The invention discloses a novel automatic hook connecting device. The invention will be further explained with reference to the drawings.

Referring to fig. 1, 2, 3 and 4, a novel automatic hook connecting device comprises an upper cover i 1, a base i 2, a revolving body i 3, an upper cover ii 4, a base ii 5, a revolving body ii 6, a spring i 7 and a spring ii 8, wherein the upper cover i 1, the upper cover ii 4, the base i 2, the base ii 5, the revolving body i 3, the revolving body ii 6, the spring i 7 and the spring ii 8 have the same structure and matching relationship, the base i 2 is provided with a guide rail 201, an ear seat 202, a guide groove 203, a ring-shaped guide rail 204, a curved groove 205 and a straight groove 206, the guide rail 201 is matched with the guide groove moving pair of the base ii 5, the guide groove 203 is matched with the guide rail moving pair of the base ii 5, so as to realize the matching and separation of the base i 2 and the base ii 5, the revolving body i 3 is provided with a revolving ring 301, a support 302 and a revolving groove 303, one end of the spring i 7 is connected with the ear seat 202, one end of the spring II 8 is connected with the support 302, one end of the spring II is connected with the second lug seat 502, the other end of the spring II is connected with the second support 602, and the rotary groove 303 can be matched with the rotary pair of the annular guide rail 204.

Preferably, the guide rail 201 and the ring-shaped guide rail 204 have a double-rail structure, and the guide groove 203 and the rotary groove 303 have a double-groove structure.

Preferably, the rod part of the rotator i 3 extends outward through the notches of the curved groove 205 and the straight groove 206, and the rotation range of the rotator i 3 is restricted through the curved groove 205 and the straight groove 206.

Preferably, the upper part of the base I2 is connected with an upper cover I1 through a bolt, and the upper part of the base II 5 is connected with an upper cover II 4 through a bolt.

Preferably, the swivel ring 301 and the second swivel ring 601 are in a plane contact state after fitting.

Referring to fig. 2, 5 and 6, the operation principle of the present invention will be described below. If figure 5 is the operating condition before the cooperation, the spring is original long state this moment, and the guide way of base I and the cooperation of the guide rail of base II, the guide rail of base I and the cooperation of the II guide ways of base, the two are each other retrains, improve centering nature. As shown in figure 6, when the rotary ring and the second rotary ring are matched, the end head at the front end of the base is provided with a plane pair to collide with the inclined plane of the rotary ring, so that the rotary ring and the second rotary ring are forced to rotate anticlockwise along the annular track, and the spring I and the spring II are gradually stretched by external force in the process until the inclined planes of the rotary ring and the second rotary ring become a plane and generate a plane contact state.
