[0023] Furthermore, one end of the second support rod 5 is hingedly connected to one end of the fourth support rod 7 through the same bearing seat, and one end of the first support rod 4 is hingedly connected to one end of the third support rod 6 through the same bearing seat. The first support rod 4, the second support rod 5, the third support rod 6 and the fourth support rod 7 are distributed on the inner wall of the silica gel bag body 1 in an equilateral parallelogram shape. The hinges of the four are closely attached to each other and have great friction. Figure 2 As shown, the opening of the silica gel bag body 1 can be stretched open and kept in the stretched state, so that it is convenient for the user to pour food.

[0024] Furthermore, a ball groove is provided on the surface of the silicone strip 8, and there are multiple groups of ball grooves, which are evenly distributed on one side of the silicone strip 8 in a linear array. A ball buckle is fixed on one side of the card strip 9, and there are multiple groups of ball buckles, which are evenly distributed on one side of the card strip 9 in a linear array. The ball buckle is adapted to the ball groove, and the two are connected by snapping. The other side of the card strip 9 is set as a silicone sheet, and the silicone sheet is tightly attached to one side of the silicone strip 8. Figure 3 As shown, the fixing and disassembly of the silica gel strip 8 and the clamping strip 9 are simple and easy to operate, and the silica gel bag body 1 is well sealed.

[0025] Furthermore, plastic limit blocks 10 are fixed on both sides of the top of the second fastening plastic plate 3, slots 11 are opened on both sides of the top of the first fastening plastic plate 2, and a return spring 12 is fixed inside the slot 11, and a triangular block 13 is slidably inserted inside the slot 11, and one end of the triangular block 13 is fixedly connected to one end of the return spring 12. Figure 3 and attached Figure 4 As shown, the first fastening plastic plate 2 and the second fastening plastic plate 3 are more difficult to separate, ensuring that air does not easily enter the silica gel bag body 1.

[0026] Further, triangular grooves are formed on both sides of the plastic limit block 10, and multiple groups of triangular grooves are provided. The multiple groups of triangular grooves are equidistantly and mirror-distributed at the top and bottom of the plastic limit block 10 in a linear array manner. The triangular grooves are adapted to the triangular clamping blocks 13, and the triangular clamping blocks 13 are slidably inserted into the interior of the triangular grooves. According to the attached Figure 3 and the attached Figure 4 shown, the plastic limit block 10 and the triangular clamping blocks 13 have multiple engaging positions, ensuring that the first fastening plastic plate 2 and the second fastening plastic plate 3 will not easily separate.

[0027] Further, four groups of triangular clamping blocks 13 are provided. The four groups of triangular clamping blocks 13 are respectively located at the inner top and bottom of each group of slots 11. Two of the groups of triangular clamping blocks 13 are mirror-distributed inside one of the groups of slots 11. According to the attached Figure 4 shown, the engaging connection effect between the triangular clamping blocks 13 and the plastic limit block 10 is better, further strengthening the fixing effect between the two.

[0028] Working principle: When in use, first rotate the first strut 4, the second strut 5, the third strut 6, and the fourth strut 7. The hinge joints of the first strut 4 and the third strut 6, and the hinge joints of the second strut 5 and the fourth strut 7 drive the two sides of the silicone bag body 1 to move closer to the center, while the hinge joints of the first strut 4 and the second strut 5, and the hinge joints of the third strut 6 and the fourth strut 7 drive the other two sides of the silicone bag body 1 to move away from each other in the opposite direction. Eventually, the opening of the silicone bag body 1 is expanded and maintained in the expanded state under the support of the four struts. Then, the user can normally pour food into the silicone bag body 1.

[0029] When encapsulation is required, first move the first fastening plastic plate 2 and the second fastening plastic plate 3 closer to each other. The first fastening plastic plate 2 and the second fastening plastic plate 3 drive the opening of the silica gel bag body 1 to merge. Then, one by one, insert the ball buckle on one side of the strip 9 into the ball groove on one side of the silica gel strip 8, and make the silica gel strip on the other side of the strip 9 closely adhere to one side of the silica gel strip 8. At the same time, the plastic limit block 10 slides into the inside of the slot 11. As the plastic limit block 10 continues to be inserted, the triangular locking block 13 is squeezed by the plastic limit block 10 and compresses the return spring 12. When the triangular locking block 13 is above the triangular groove on the surface of the plastic limit block 10, the triangular locking block 13 is no longer squeezed. Under the rebounding action of the return spring 12, the triangular locking block 13 slides into the triangular groove, so that the plastic limit block 10 will not easily slide out of the slot 11 in the reverse direction, thereby realizing the fixation of the distance position between the first fastening plastic plate 2 and the second fastening plastic plate 3. Stop when the plastic limit block 10 continues to slide inside the slot 11 until it can no longer move. If you want to open the silica gel bag body 1, you can directly pull the first fastening plastic plate 2 and the second fastening plastic plate 3 away from each other, and the plastic limit block 10 is pulled out of the slot 11, and the strip 9 is separated from the silica gel strip 8, so that the opening of the silica gel bag body 1 is exposed. The above is the entire working principle of the present utility model.

[0030] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model. Any reference signs in the claims should not be regarded as limiting the claimed rights.
