Abstract
Official abstract text for this publication.
The present invention relates to a fastening device for preventing the separation of injection molding parts, in which two parts formed of plastics by injection molding can be coupled to or decoupled from each other without using any additional coupling members through the improvement of the coupling structure thereof. To this end, in a fastening device for preventing the separation of injection molding parts, in which a first part ( 11 ) is formed with an elastic piece ( 12 ) having a coupling hole ( 13 ) to hold a hook ( 17 ) formed on a second part ( 14 ), the second part ( 14 ) has a coupling member ( 16 ) integrally formed at one side of the second part ( 14 ) and having a space part ( 15 ), equal to or larger than the thickness of the elastic piece ( 12 ) twice or more, and the hook ( 17 ) formed on the inside of the coupling member ( 16 ) so as to be held in the coupling hole ( 13 ) of the elastic piece ( 12 ), and the elastic piece ( 12 ) formed with the coupling hole ( 13 ) has a handle part ( 12 a ) to be exposed to the upper portion of the coupling member ( 16 ) so as to be positioned in the space part ( 15 ) of the coupling member ( 16 ) when the first part ( 11 ) and the second part ( 14 ) are coupled to each other.
First claim

1 . A fastening device for preventing the separation of injection molding parts, in which a first part ( 11 ) is formed with an elastic piece ( 12 ) having a coupling hole ( 13 ) such that a hook ( 17 ) formed on a second part ( 14 ) is held in the coupling hole ( 13 ) so as to be held therein, characterized in that: the second part ( 14 ) has a coupling member ( 16 ), which is integrally formed at one side of the second part ( 14 ) and has a space part ( 15 ) equal to or larger than the thickness of the elastic piece ( 12 ) twice or more, the coupling member ( 16 ) has the hook ( 17 ) formed on the inside of the coupling member ( 16 ) so as to be held in the coupling hole ( 13 ) of the elastic piece ( 12 ), and the elastic piece ( 12 ) formed with the coupling hole ( 13 ) has a handle part ( 12 a) formed to be exposed to the upper portion of the coupling member ( 16 ) when the first part ( 11 ) and the second part ( 14 ) are coupled to each other such that the elastic piece ( 12 ) is coupled so as to be positioned in the space part ( 15 ) of the coupling member ( 16 ). 2 . The fastening device for preventing the separation of injection molding parts according to claim 1 , wherein reinforcement pieces ( 18 ) are integrally formed at an upper portion and a lower portion on the outside of the coupling member ( 16 ).
