Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, do not limit the utility model.
As shown in Figure 1A ~ 3, the utility model embodiment relates to a kind of jack protective device, comprising:
Protective film, is arranged in jack, and its diameter is less than the internal diameter of jack;
Elastic connecting strip, one end is fixed in jack, and the other end is connected with Protective film.
Protective film P is circular, and material can select plastic cement or plastics, and main feature is that requirement is not yielding and wear-resistant.The position of circular Protective film P and Plug contact is set to contact site.Contact site can be a recessed concave surface to jack bottom direction.Such as, circle centre position is provided with a pyramid type concave point, complementary with the pyramidal structure of plug insertion pin front end.Can increase the lifting surface area of circular Protective film P like this, reduce pressure, make circular Protective film P more durable, another one advantage is that plug is more easily located.In addition, contact site is a cross open, and when such plug inserts, plug can strut cross open, and then passes, and when plug is extracted, the elastic deformation of cross open restores to the original state, and then closing openings, protection jack.
Elastic connecting strip L can be two, is symmetricly set on circular Protective film P two ends; Also can be three, evenly be connected to circular Protective film P, even can be many, but, it is noted that elastic connecting strip L can not affect the result of use that plug inserts jack.Elastic connecting strip L requires that elastic force is little, and user can overcome elastic force and inserts in labour-saving very much, and when not receiving external force, Protective film just in time can be moved to jack top and block jack by length.The inwall of jack is arranged two symmetrical grooves or three grooves are evenly set, elastic connecting strip is separately fixed in groove.
As shown in Figure 1B, 1C, Protective film is positioned at the top of jack when plug does not insert; The bottom of described jack is positioned at when plug inserts.During concrete use, plug is inserted jack by user, and circular Protective film P is pushed to jack bottom direction by plug, and circular Protective film P drives elastic connecting strip L, makes it that elastic deformation occur, and is the most allly forced into jack least significant end.Because circular Protective film P thickness is low and elastic connecting strip L elastic force is less, so plug can not be allowed to eject from the inside, user can not be affected and normally use.
