Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of packaging, and specifically relates to a food packaging bag with an exhaust structure. Background Art
[0002] Food packaging bags are a common tool for packaging food. They are usually made of plastic or paper, which can effectively protect food from the external environment, extend its shelf life, and increase the aesthetics and sales value of the product.
[0003] In existing food packaging bags, most of them use the form of air extraction to extract the air in the packaging bag. This can reduce the oxygen in the bag, prevent the reproduction of microorganisms, and slow down the oxidation and deterioration of food, thereby improving the shelf life of food. However, if the air extraction pump breaks down and the size of the replacement does not match the air extraction hole, the operator needs to purchase it again, which will increase the economic cost. Content of the Utility Model
[0004] The purpose of the utility model is to provide a food packaging bag with an exhaust structure to solve the problems raised in the above background art.
[0005] To achieve the above purpose, the utility model provides the following technical solution: A food packaging bag with an exhaust structure, including a packaging bag body. A carrying handle is opened at the top of the packaging bag body. A one-way exhaust valve is arranged on the left side of the packaging bag body. An adjusting mechanism is arranged on the left side of the packaging bag body. A clamping mechanism is arranged on the left side of the packaging bag body, which can clamp the air extraction pump to prevent it from falling off. The adjusting mechanism includes:
[0006] An installation disc, the right side of the installation disc is fixedly installed on the left side of the packaging bag body. An inclined groove is opened on the right side of the installation disc. A return spring is fixedly installed in the groove of the installation disc, which can make the positioning block reset after being squeezed.
[0007] A positioning block, the left side of the positioning block is fixedly installed on the right side of the return spring. The outer wall of the positioning block is slidably installed in the groove of the installation disc. A moving column is slidably installed on the inner wall of the inclined groove. When the one-way exhaust valve rotates, the moving column can move in the inclined groove. When moving, the moving column can move in the moving groove, which can make the inner circles of the four arc-shaped plates enlarge or shrink. The one-way exhaust valve is rotatably installed on the right side of the installation disc.
[0008] Preferably, a moving groove is opened on the front surface of the one-way exhaust valve. The outer wall of the moving column is slidably installed in the moving groove. A positioning hole is opened on the front surface of the one-way exhaust valve, which is convenient to be clamped into the positioning block when rotating, so as to fix the installation disc and the one-way exhaust valve. An arc-shaped plate is fixedly installed on the outer wall of the moving column.
[0009] Preferably, the clamping mechanism includes an L-shaped rod. The right side of the L-shaped rod is fixedly installed on the left side of the arc-shaped plate, which facilitates the installation of the fixing plate to fix the telescopic spring. The top of the L-shaped rod is fixedly installed with a fixing plate. The right side of the fixing plate is fixedly installed with a telescopic spring. The end of the telescopic spring away from the fixing plate is fixedly installed with a clamping plate.
[0010] Preferably, the positioning holes are arranged in a circular array centered on the center of the one-way exhaust valve, which facilitates the insertion of the positioning blocks to fix the mounting disc to the one-way exhaust valve.
[0011] Preferably, the moving columns, arc-shaped plates, and clamping mechanisms are arranged in a circular array centered on the center of the one-way exhaust valve, and there are four groups. When the one-way exhaust valve rotates, the four arc-shaped plates can be simultaneously moved closer to the middle, so that the size of the arc-shaped plates can be adjusted.
[0012] Preferably, the L-shaped rods and telescopic springs are arranged in a circular array centered on the center of the arc-shaped plate, and there are two groups, which can make the installation of the fixing plate more stable, and the tension plate can be better reset after being squeezed.
[0013] Compared with the prior art, the present invention provides a food packaging bag with an exhaust structure, having the following beneficial effects:
[0014] 1. For the food packaging bag with an exhaust structure, when the air extraction pump cannot be inserted into the one-way exhaust valve, by rotating the one-way exhaust valve, the positioning block is disengaged from the current positioning hole and then enters the appropriate positioning hole. At this time, the moving column will slide along the inclined groove, so that the arc-shaped plates can move towards the middle or towards the outside at the same time, so that the inner diameter of the arc-shaped plates can be adjusted, which is convenient for air extraction pumps with different diameters to be inserted, increasing the versatility of the one-way exhaust valve.
[0015] 2. For the food packaging bag with an exhaust structure, when the air extraction pump is inserted, it will squeeze the clamping plate, so that the clamping plate drives the telescopic spring to compress. After the air extraction pump is clamped, the telescopic spring will drive the clamping plate to clamp against the inner wall of the air extraction pump, which can prevent the air extraction pump from accidentally falling off during operation, resulting in the need to re-insert.

Specific embodiments
[0022] As Figures 1 - 5 shown, the present utility model provides a technical solution: a food packaging bag with an exhaust structure, including a packaging bag body 1. A carrying handle 2 is provided at the top of the packaging bag body 1 for convenient taking of the packaging bag body 1. A one-way exhaust valve 3 is provided on the left side of the packaging bag body 1 for facilitating the exhaust of the interior of the packaging bag body 1. An adjusting mechanism 4 is provided on the left side of the packaging bag body 1 to adjust the size of the one-way exhaust valve 3. A clamping mechanism 5 is provided on the left side of the packaging bag body 1 to facilitate clamping of the air pump.
[0023] Specifically, the adjusting mechanism 4 includes: a mounting disc 41, an inclined groove 42, a return spring 43, a positioning block 44, a moving column 45, a moving groove 46, a positioning hole 47, and an arc-shaped plate 48. The right side of the mounting disc 41 is fixedly installed on the left side of the packaging bag body 1. An inclined groove 42 is provided on the right side of the mounting disc 41. The return spring 43 is fixedly installed in the groove of the mounting disc 41. The left side of the positioning block 44 is fixedly installed on the right side of the return spring 43. When the one-way exhaust valve 3 rotates, the positioning block 44 can be disengaged from the positioning hole 47 and then rotated to a suitable position. The return spring 43 will reset the positioning block 44 so that it is inserted into another positioning hole 47. The outer wall of the positioning block 44 is slidably installed in the groove of the mounting disc 41. The inner wall of the inclined groove 42 is slidably installed with the moving column 45. The one-way exhaust valve 3 is rotatably installed on the right side of the mounting disc 41. A moving groove 46 is provided on the front surface of the one-way exhaust valve 3. When the one-way exhaust valve 3 rotates, the moving column 45 can slide in the inclined groove 42. At this time, the moving column 45 will move in the moving groove 46 during the moving process, so as to be pushed by the arc-shaped plate 48. The outer wall of the moving column 45 is slidably installed in the moving groove 46. Positioning holes 47 are provided on the front surface of the one-way exhaust valve 3. The positioning holes 47 are circumferentially arranged around the center of the one-way exhaust valve 3, which is convenient for the positioning block 44 to be inserted to fix the mounting disc 41 and the one-way exhaust valve 3. The outer wall of the moving column 45 is fixedly installed with the arc-shaped plate 48. The moving column 45, the arc-shaped plate 48, and the clamping mechanism 5 are circumferentially arranged around the center of the one-way exhaust valve 3 and are provided in four groups. When the one-way exhaust valve 3 rotates, the four arc-shaped plates 48 can be simultaneously moved closer to the middle, so that the size of the arc-shaped plate 48 can be adjusted.
[0024] Specifically, the clamping mechanism 5 includes: an L-shaped rod 51, a fixing plate 52, a telescopic spring 53, and a clamping plate 54. The right side of the L-shaped rod 51 is fixedly installed on the left side of the arc-shaped plate 48. The top of the L-shaped rod 51 is fixedly installed with the fixing plate 52. The telescopic spring 53 is fixedly installed on the right side of the fixing plate 52. The L-shaped rod 51 and the telescopic spring 53 are circumferentially arranged around the center of the arc-shaped plate 48 and are provided in two groups, which can make the installation of the fixing plate 52 more stable and the clamping plate 54 better reset after being squeezed. The end of the telescopic spring 53 away from the fixing plate 52 is fixedly installed with the clamping plate 54. When the air pump is installed, the inclined surface of the clamping plate 54 will be squeezed, so that the telescopic spring 53 is compressed. After being inserted, the telescopic spring 53 will drive the clamping plate 54 to squeeze the inner wall of the air pump to fix the air pump and prevent it from falling off.
[0025] Working principle: When the air extraction pump cannot be inserted into the one-way exhaust valve 3, by rotating the one-way exhaust valve 3, the positioning block 44 is disengaged from the current positioning hole 47, and the return spring 43 is compressed. Then it enters into a suitable positioning hole 47. At this time, the positioning block 44 is reset by the return spring 43. At the same time, the moving column 45 slides along the inclined groove 42, and the moving column 45 also slides in the moving groove 46 while sliding. In this way, the arc-shaped plate 48 can move towards the middle or towards the outside at the same time, so that the inner diameter of the arc-shaped plate 48 can be adjusted, which is convenient for air extraction pumps with different diameters to be inserted, and increases the versatility of the one-way exhaust valve 3.
[0026] When the air extraction pump is inserted, it will be inserted from the inclined surface of the clamping plate 54, and at the same time, the clamping plate 54 is squeezed to move to the left. At this time, the telescopic spring 53 is squeezed and compressed to the right side of the fixing plate 52. After the air extraction pump is clamped in, the telescopic spring 53 will drive the clamping plate 54 to clamp against the inner wall of the air extraction pump, which can prevent the air extraction pump from accidentally falling off during operation, resulting in the need to re-insert it.
[0027] The above has generally described the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, the modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
