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.
In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and for simplicity of description, but do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.
Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless specifically limited otherwise.
Referring to fig. 1-3, an upper cover of a micro tube comprises a tube cap shell 1, wherein an outer edge 2 is arranged at a bottom port of the tube cap shell 1, a protective groove is also arranged at the outer side of the tube cap shell 1, and the outer edge 2 and an anti-slip groove can be used for conveniently covering and taking down the upper cover.
The top in the pipe cap shell 1 is provided with a cavity 4 through an elastic membrane 5 in a separated mode, the height of the cavity 4 is 1/3-1/4 of the height of the whole pipe cap shell 1, the height of the cavity 4 can ensure that a pipe opening is tightly attached to the elastic membrane 5 after a pipe body 3 enters, and a friction rubber ring 6 is arranged below the elastic membrane 5 in the pipe cap shell 1.
Wherein, elastic membrane 5 is the rubber membrane, and the periphery of elastic membrane 5 and the inner wall sealing connection of pipe cap shell 1, and elastic membrane 5 is the level under the natural state and tightens the state, and the elastic membrane 5 that is not extrudeed keeps natural tension, and the level is tightened.
Moreover, the top wall in the pipe cap shell 1, namely the top wall of the cavity 4, can be provided with a spongy cushion, the spongy cushion can avoid the quick jacking of the pipe body 3, the elastic film 5 is broken due to the contact with the top wall of the pipe cap shell 1, and the spongy cushion can be subjected to buffering protection.
Bottom mouth department in the pipe cap shell 1 is provided with friction rubber ring 6, and the medial extremity face of friction rubber ring 6 evenly is provided with anti-skidding groove, and when 1 lid of pipe cap shell was established on body 3, the outer wall friction extrusion contact of friction rubber ring 6 in the pipe cap shell 1 and body 3, the anti-skidding groove on the friction rubber ring 6 be convenient for with 3 friction contact of body, can carry out spacing fixed to body 3.
In this embodiment, the upper cover of the micro-tube is composed of a tube cap shell 1, an elastic membrane 5 and a friction rubber ring 6, and the outer edge 2 of the bottom port of the tube cap shell 1 can be conveniently covered and taken down.
When the pipe cap shell 1 covers and establishes on body 3, the outer wall friction extrusion contact of friction rubber ring 6 in the pipe cap shell 1 and body 3 can be fixed body 3 is stable, avoids pipe cap shell 1 to drop easily on body 3, and the mouth of pipe extrusion elastic membrane 5 of body 3 stretches into cavity 4 moreover, and elastic membrane 5 receives behind the extrusion self elastic action down carries out the closing cap to the mouth of pipe for the mouth of pipe of body 3 is sealed relatively.
When the upper cover is taken down from the pipe body 3, the outer edge 2 is upwards pushed through the fingernail, so that the upper cover slowly withdraws from the pipe body 3, the pipe orifice leaves the elastic membrane 5, and the elastic membrane slowly withdraws from the friction rubber ring 6, and the upper cover can be conveniently and easily taken down.
The utility model discloses in, little buret's upper cover can be fixed 3 stable of body through friction rubber ring 6, avoids pipe cap shell 1 to drop easily on body 3, carries out the closing cap to the mouth of pipe under the self elastic action after receiving the extrusion through elastic membrane 5 for the mouth of pipe of body 3 is sealed relatively.
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.
