Description

Internal pushing type one-key pushing sealing structure for elastic sealing sleeve

Technical Field

The utility model relates to plugging and sealing applied to a medium container, in particular to an internal pushing type one-key pushing sealing structure for an elastic sealing sleeve.

Background

In the shipping container industry, it is very common to manufacture bottles, cans, etc. having one or more spouts and/or injection ports. The opening of such containers has internal threads incorporated into the sealing surface of the threadless gasket and an externally threaded sealing plug carrying an annular sealing gasket is threadably engaged with the opening of the container. When the plug is inserted into the seal, the plug gasket is pressed against the unthreaded gasket sealing surface, resulting in an effective seal against the container. When a plurality of bottles, cans and other containers are sealed in the above manner, on one hand, the pressing force of the sealing plug and the gasket thereof is critical, on the other hand, the threads of the opening of the container are merged into the seat surface of the gasket of the opening gasket, when the sealing plug is sealed and plugged into the opening of the container by applying necessary force, the gasket of the sealing plug is wedged into the starting position of the threads in the opening to be sealed, when the sealing plug is screwed off, the gasket of the sealing plug is wedged into the threads of the opening to tightly support the gasket of the sealing plug, when the knob of the sealing plug continues, the sealing gasket is easy to generate a releasing force, even when the sealing plug is separated from the opening, the gasket can still be sunk into the threads of the opening in the sealing plug, so that the gasket is separated from the gasket seat of the sealing plug, and the gasket and the opening are easy to form a leakage passage, thereby damaging the gasket and affecting the sealing effect. With frequent use, the gasket itself is gradually damaged by the application of force, slowly impairing the sealing action of the gasket.

The sealing effect is generated by the engagement of the sealing plug gasket and the sealing plug, the dragging of the sealing plug to the sealing gasket caused by the mutual engagement of threads is inevitably generated when the sealing plug is taken out, the problems are inevitably generated early or late, and the sealing plug and the gasket cannot be durably used through the threaded sealing connection.

In order to solve the technical problem, chinese patent CN104803085A discloses a container plug capable of being opened and closed quickly, which includes a cylindrical plug body, the cylindrical plug body includes a plug rod, a base is disposed at the bottom of the plug rod and can be inserted into or pulled out of the container, the shape and size of the base are matched with the shape and size of the straight section of the container mouth or the minimum section of the container, an annular plug body is disposed at the upper portion of the base, a flexible sealing sleeve capable of being bent is disposed between the annular plug body and the base, the annular plug body and the base can move mutually in the container mouth along the axial direction of the container under the external force to extrude the flexible sealing sleeve, so that the flexible sealing sleeve expands radially and bends outwards to form a sealing ring between the container and the base, and the sealing ring and the base together form a sealing layer for realizing quick closing of the container. It selects the bottle stopper without screw thread, can open and close the use fast. However, in the technical scheme, the radial size of the elastic sealing body after being extruded and expanded is larger than the inner diameter of the container, the contact area of the elastic sealing body after being folded and expanded in the structure and the inner diameter of the container is small, and the sealing effect is unstable. In addition, in the process of realizing the closure of the container stopper in the prior art, the whole stopper body is firstly placed into the container, and then the base is pulled to extrude the elastic sealing sleeve to realize the sealing effect, the operation action is not simple and convenient enough, the opening and closing operation fingers can only operate in the set direction of the stopper body, and the real quick opening and closing are not realized.

As a sealing and sealing member for a container, how to rapidly realize the sealing and sealing of the container by a sealing plug through one-step operation on the basis of ensuring the stability of sealing is a technical problem to be solved urgently by those skilled in the art.

An internally-pushed one-key-pushed sealing structure for an elastic sealing sleeve as claimed in claim 2, wherein: the pushing starting device comprises a starting piece and a lever, the starting piece is slidably mounted on a fixed frame of the sliding block guide block, and the lever is pivotally connected to the fixed frame and takes the fixed frame as a fulcrum; one end of the lever is arranged at the lower end of the starting piece, the upper part of the other end of the lever is lapped with the sliding block supporting frame, and the bottom of the sliding block supporting frame is provided with a sliding block guide cavity for guiding the circumferential part of the sliding block to push to the inner wall of the container opening; the sliding block supporting frame is arranged on the periphery of the fixed frame, and the fixed frame is provided with an inverted conical inclined surface facing the sliding block supporting frame;

8. An internally-pushed one-key-pushed sealing structure for an elastic sealing sleeve as claimed in claim 7, wherein: the starting part is provided with a spring pin, the matching part of the upper part of the sliding block support frame is provided with a clamping groove, and when the sliding block support frame moves upwards, the spring pin is clamped into the clamping groove to lock the sliding block support frame and the starting part so as to realize the locking of the starting part and the sliding block support frame.

9. An internally-pushed one-key-pushed sealing structure for an elastic sealing sleeve as claimed in claim 7, wherein: the lever is characterized by further comprising a pin, wherein the pin is mounted on the fixed frame, and the lever swings up and down in a pivoting mode by taking the pin as a fulcrum.

10. An internally pushed one-key push seal arrangement for an elastomeric boot as claimed in claim 8, wherein: the spring pin side wall surface is provided with a convex block, the starting piece is provided with a button, the lower end of the button is provided with an extended section in an inverted T shape, the extended section of the button penetrates through the side wall of the spring pin, the inverted T shape is limited by the convex block arranged on the spring pin when the spring pin is not popped, the button is limited to rebound and reset to a preset height position, the spring pin is driven after being popped to remove the limitation to the inverted T shape by the convex block of the spring pin, the rebound and reset of the button to the preset height are realized, and the locking of the spring pin is realized by matching the distance between the convex block of the spring pin and the inverted T shape.
