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 (12a) 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.
Description
technical field [0001] The present invention relates to a fastening device for preventing separation of injection molded parts, in which fastening device two parts formed of plastic by injection molding are coupled without using any additional coupling members, which can be achieved by improving both The coupling structure between the two components without using any additional tools, whereby the two components coupled to each other can be easily separated from each other. Background technique [0002] In general, when two parts formed of plastic by injection molding are assembled to each other using a coupling member such as a screw, it is possible to lower its assembly performance, fearing that a defective product will be made due to screw coupling failure. In addition, in order to separate the two components for maintenance or the like, an additional tool for releasing the screws is required, thereby making the work inconvenient. [0003] Therefore, recently, in order to...
