Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: an anti-impact end socket comprises an end socket body 1, wherein a support rod 8 is fixedly connected at the center of the bottom of the end socket body 1, a sliding sleeve 7 is sleeved on the outer surface of the support rod 8, a metal elastic plate 5 is installed on the outer end face of the sliding sleeve 7, a limiting ring 4 with an L-shaped cross section is fixedly connected at the periphery of the top of the end socket body 1, a rotating ring 10 is arranged on the inner side of the limiting ring 4, the inner wall of the rotating ring 10 is fixedly connected with the outer wall of the metal elastic plate 5, the rotating ring 10 is limited by the limiting ring 4 and does not limit the rotating ring 10 to rotate on the inner side of the limiting ring 4, the sliding sleeve 7 can rotate and slide on the outer surface of the support rod 8, when the end socket body 1 is impacted, impact force is firstly contacted with the metal elastic plate 5, the metal elastic plate 5 is elastically deformed and drives a return spring 9 to elastically contract, and the impact force is buffered, and, transmit partial impact force to swivel 10 through metal springboard 5, partly convert the impact force part into the impact force to the spacing ring 4 outside through swivel 10, and partial conversion is the extrusion force all around to head body 1 bottom, because head body 1 bottom thickness all around is great to there is the exterior wall of container to support, and thus less to head body 1 influence.

Specifically, as shown in fig. 1 and fig. 3, top periphery fixedly connected with inner ring 2 of head body 1, multiunit mounting groove 11 has been seted up to inner ring 2's outer end personally submits annular equidistance, the inboard fixedly connected with metal shrapnel 3 of mounting groove 11, in this device, the outer table wall of inner ring 2 and the inner wall laminating of container, before the head welding, with inner ring 2 sliding fit to the inboard of container, inner wall through the container extrudees metal shrapnel 3 to the inboard of mounting groove 11, produce the extrusion force to the container inner wall through metal shrapnel 3, thereby it is fixed with inner ring 2 and head body 1 and container, the operator of being convenient for welds between head body 1 and container, and simultaneously, after the welding is accomplished, metal shrapnel 3 still lasts and produces the extrusion force to the container, thereby the stability of being connected between head body 1 and container has been promoted.

Specifically, as shown in fig. 1 and 2, metal elastic plate 5 is the cambered surface structure of top indent, and metal elastic plate 5's bottom is annular equidistance fixedly connected with multiunit protruding wing 6, the surface of bracing piece 8 is located and is equipped with reset spring 9 between head body 1 and the sliding sleeve 7, setting through protruding wing 6, when metal elastic plate 5 receives the impact force of slope, can contact the extrusion with protruding wing 6 during the impact force, thereby drive metal elastic plate 5 and swivel 10 and rotate, part impact force is cushioned through frictional force when rotating, impact resistance has been promoted, reset spring 9's setting, cushion impact force, and can assist metal elastic plate 5 to reset.

The working principle is as follows: when the sealing head is used, when the sealing head body 1 is impacted, the sealing head body is firstly contacted with the metal elastic plate 5, the metal elastic plate 5 is elastically deformed and drives the reset spring 9 to elastically contract, the impact force is buffered through the potential energy of the elastic contraction of the metal elastic plate 5 and the reset spring 9, and part of the impact force is transmitted to the rotating ring 10 through the metal elastic plate 5, convert the impact force part into the impact force to the outside of spacing ring 4 through change ring 10, the part conversion is to 1 bottom extrusion force all around of head body, because 1 bottom of head body thickness all around is great, and the exterior wall that has the container supports, thereby it is less to influence head body 1, when the impact force that metal elastic plate 5 received has certain inclination, can contact the extrusion with protruding wing 6 during the impact force, thereby it rotates to drive metal elastic plate 5 and change ring 10, the part impact force is cushioned through frictional force when rotating, impact resistance has been promoted.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
