Problems solved by technology

However, people have found in actual use that this type of technical solution still needs to be connected with other air extraction devices to cooperate with it, which has a very complicated operation process and still does not have good convenience in essence. Transshipment brings great inconvenience

Embodiment 1

[0042] Embodiment 1: The piston driving assembly 41 includes a rotating seat 411 and a central rod 412;

[0043] The rotating seat 411 is in the shape of a stepped shaft with a large top and a small bottom. The lower part of the rotating seat 411 extends into the seat body 32 and fits with the inner wall of the seat body 32. The upper part of the rotating seat 411 is erected on the seat body. On the top surface of the body 32, a threaded hole 4110 is provided in the rotating seat 411;

[0044] The central rod 412 is arranged in the threaded hole 4110, and the bottom end of the central rod 412 is fixedly connected with the bottom of the seat body 32 in the base 3 through a connecting rod, and the top of the central rod 412 is also fixedly connected with a limit ring 4120 ;

[0045] The middle part of the piston 421 is provided with a slide hole adapted to the central rod 412, and the outer wall of the piston 421 is provided with an external thread adapted to the threaded hole ...

Embodiment 2

[0049] Embodiment 2: The piston driving assembly 41 includes a sliding seat 413, a connecting rod 414, a gland 415 and a compression spring 416;

[0050] The sliding seat 413 is arranged in the seat body 32 and is fixedly connected with the inner wall of the seat body 32. A vertical sliding hole 4130 is opened in the middle of the sliding seat 413, and the piston 421 is slidably connected to the vertical sliding hole 4130. Middle and airtight with the inner wall of the vertical sliding hole 4130;

[0051] One side of the gland 415 is hinged on the top surface of the slide seat 413, and the other side is fixedly connected to the top of the stage clip 416, and the bottom end of the stage clip 416 is fixedly connected to the top surface of the slide seat 413. , the two ends of the connecting rod 414 are respectively hinged on the bottom surface of the gland 415 and the top surface of the piston 421 . In this way, each time the operator presses down on the gland, the piston will ...

Abstract

The invention provides a sealing device for a packaging bag and relates to the field of packaging bag structures. The sealing device is exquisite in structure, convenient to use and suitable for packaging bags of various structural forms. When the sealing device is used, autonomous air extraction can be conducted conveniently without an external air extractor. The sealing device comprises a bag opening sealing strip assembly, an inner frame body, a base and a vacuumizing assembly. A bag opening of the packaging bag is divided into a first sheet-shaped bag opening body and a second sheet-shaped bag opening body after being folded or clipped. In use, the sealing device solves the biggest problem in the prior art, in other words, the purpose that no other external vacuumizing device is needed is achieved, and the requirement in daily life is met even though the vacuum degree of the packaging bag treated through the sealing device is low. In this way, by means of the scheme, the size is smaller, the application range is wider, the sealing device can be used under various environments such as the environment that no power source or other external device exits, and the overall sealing device has the beneficial effects of being exquisite in structure, convenient to use, good in stability and wide in application range.

Description

technical field [0001] The invention relates to the field of packaging bag structures. Background technique [0002] At present, in order to prolong the fresh-keeping period of food, people usually use vacuum packaging bags to seal and package food. However, when people unpack the packaging bags for eating, the remaining food in the bags will be quickly oxidized. In order to avoid such problems, the existing technology Proposed a variety of vacuuming devices, so that the remaining food in the bag is stored in a vacuum state. A representative example is a Chinese utility model patent titled "Vacuum Sealed Bag" with an application number of "200920066869.0" announced by the National Bureau on December 30, 2009. However, people have found in actual use that this type of technical solution still needs to be connected with other air extraction devices for use in conjunction with it, which has a very complicated operation process and still does not have good convenience in essenc...
