Description

Technical Field

[0001] The present invention relates to the technical field of hooks, and specifically to an automatic hook connection device. Background Art

[0002] The hook connection device is a common structure for connecting two components, such as the connection of vehicle compartments, seat belts, schoolbag straps, etc. However, the current hooks have disadvantages such as poor centering, bulky structure, easy detachment under heavy objects, and poor self-locking performance. Therefore, the prior art needs to be further improved. Summary of the Invention

[0003] In view of the above problems, the present invention provides a new type of automatic hook connection device.

[0004] The present invention adopts the following technical solutions:

[0005] A new type of automatic hook connection device includes upper cover I, base I, rotating body I, upper cover II, base II, rotating body II, spring I, and spring II. The upper cover I and upper cover II, base I and base II, rotating body I and rotating body II, spring I and spring II have the same structure and cooperation relationship. The base I is provided with a guide rail, ear seat, guide groove, annular guide rail, curved groove, and straight groove structure, and is movably matched with the guide groove of the base II through the guide rail, and movably matched with the guide rail of the base II through the guide groove, so as to realize the cooperation and separation of the base I and base II. The rotating body I is provided with a rotating ring, a support, and a rotating groove. One end of the spring I is connected to the ear seat, and one end is connected to the support. The rotating groove can be rotatably matched with the annular guide rail;

[0006] Wherein, the rod part of the rotating body I extends out through the notch of the curved groove and the straight groove, and the rotation range of the rotating body I is restricted by the curved groove and the straight groove;

[0007] Wherein, the rotating body II includes a second rotating ring. During the cooperation, due to the flat surface of the front end of the base colliding with the inclined surface of the rotating ring, the rotating ring and the second rotating ring are forced to rotate counterclockwise along their annular tracks. During this process, the spring I and spring II are gradually stretched by the external force until the inclined surfaces of the rotating ring and the second rotating become flat and a flat contact state is generated;

[0008] Wherein, in the working state after cooperation, the spring I and spring II return to their original lengths due to the elastic force, and the rotating ring and the second rotating ring rotate in the reverse direction to return to the initial state. The self-locking condition is formed by the structural difference between the rotating ring and the front end head and the outer extension ends of the rotating ring and the second rotating ring being stuck on the side line of the straight groove.

[0009] Preferably, the guide rail and the annular guide rail are double-track structures, and the guide groove and the rotating groove are double-groove structures.

[0010] Preferably, an upper cover I is bolted above the base I, and an upper cover II is bolted above the base II.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: adopting a central symmetric structure, using the guide rails and guide grooves of the left and right parts to mutually constrain each other, having good centering performance, being able to automatically return to the center by using the elastic restoring force of the spring during the feeding cooperation, and having good self-locking performance after returning to the center. The structure of the present invention is simple, the price is low, and the practicability is strong. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE INVENTION

[0019] The present invention discloses a new type of automatic hook connection device. The present invention will be further described below with reference to the accompanying drawings.

[0020] Refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4, a new type of automatic hook connection device, including upper cover Ⅰ1, base Ⅰ2, rotating body Ⅰ3, upper cover Ⅱ4, base Ⅱ5, rotating body Ⅱ6, spring Ⅰ7, and spring Ⅱ8. The upper cover Ⅰ1 and upper cover Ⅱ4, base Ⅰ2 and base Ⅱ5, rotating body Ⅰ3 and rotating body Ⅱ6, spring Ⅰ7 and spring Ⅱ8 have the same structure and mating relationship. The base Ⅰ2 is provided with a guide rail 201, an ear seat 202, a guide groove 203, an annular guide rail 204, a bent groove 205, and a straight groove 206. It is movably mated with the guide groove of the base Ⅱ5 through the guide rail 201 and movably mated with the guide rail of the base Ⅱ5 through the guide groove 203, so as to realize the mating and separation of the base Ⅰ2 and the base Ⅱ5. The rotating body Ⅰ3 is provided with a rotating ring 301, a support 302, and a rotating groove 303. One end of the spring Ⅰ7 is connected to the ear seat 202, and one end is connected to the support 302. One end of the spring Ⅱ8 is connected to the second ear seat 502, and one end is connected to the second support 602. The rotating groove 303 can be rotatably mated with the annular guide rail 204;

[0021] Wherein, the rod part of the rotating body Ⅰ3 extends out through the notches of the bent groove 205 and the straight groove 206, and the rotation range of the rotating body Ⅰ3 is restricted by the bent groove 205 and the straight groove 206;

[0022] Wherein, the rotating body Ⅱ6 includes a second rotating ring 601. In the working state after mating, the springs Ⅰ7 and Ⅱ8 return to their original lengths due to elastic force, and the rotating ring 301 and the second rotating ring 601 rotate in opposite directions and return to the initial state. The self-locking condition is formed by the structural difference between the rotating ring 301 and the front end head and the outer extension ends of the rotating ring 301 and the second rotating ring 601 being stuck on the side line of the straight groove 206.

[0023] Preferably, the guide rail 201 and the annular guide rail 204 are of double-track structure, and the guide groove 203 and the rotating groove 303 are of double-groove structure.

[0024] Preferably, the upper cover Ⅰ1 is bolted above the base Ⅰ2, and the upper cover Ⅱ4 is bolted above the base Ⅱ5.

[0025] Preferably, the rotating ring 301 and the second rotating ring 601 are in a plane contact state after mating.

[0026] Refer to Figure 2 , Figure 5 , Figure 6 , the working principle during its specific use is described below. As Figure 5 For the working state before mating, at this time the spring is in the original length state. The guide groove of the base Ⅰ is mated with the guide rail of the base Ⅱ, and the guide rail of the base Ⅰ is mated with the guide groove of the base Ⅱ. The two are mutually restricted to improve the centering. As Figure 6To match the working state during mating, during the mating process, since the end at the front end of the base has a planar pair that collides with the inclined surface of the rotary ring, it forces both the rotary ring and the second rotary ring to rotate counterclockwise along their annular tracks. During this process, Spring I and Spring II are gradually stretched by the external force until the inclined surfaces of the rotary ring and the second rotary become flat and a planar contact state is generated. As Figure 2 shown, the rotary body II includes the second rotary ring. In the working state after mating, Spring I and Spring II return to their original lengths due to the elastic force, and the rotary ring and the second rotary ring rotate in the reverse direction and return to the initial state. By utilizing the structural differences between the rotary ring and the front end and the fact that the outer extended ends of the rotary ring and the second rotary ring are stuck on the side lines of the straight groove, the self-locking condition can be formed. When releasing the connection relationship, as long as the outer extended sections of the rotary body and the second rotary body are rotated to make the inclined surface contact between the rotary ring and the second rotary ring become a horizontal surface contact, the self-locking state can be released and the mating relationship can be separated.
