[0073] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0074] Compare with Figure 1 、 2 , Figure 1 This is an exploded top view of one embodiment of the present invention. Figure 2 This is an exploded view from above of one of the embodiments of the present invention. In this embodiment, the bolt-type buckle is composed of three parts, 100 is a buckle seat, 200 is a press buckle, and 300 is a bolt. The bolt 300 is installed on the buckle seat 100 through a thread. The buckle seat 100 is in a circular ring shape, and the thread 120 is located on the outside of the ring. There is a buckle rod 110 on the buckle seat 100. The buckle rod 110 is a beam with both ends on the ring. The hollow holes on both sides of the buckle rod 110 are hole position A101 and hole position B102 respectively. At the same time, there is a limiting groove 105 on the buckle seat 100; the press buckle 200 is located between the bolt 300 and the buckle seat 100, and there is a buckle on the press buckle 200. The pressure beam 201 has a limit pin 211 at a position corresponding to the limit slot 105 on the buckle seat 100; when in use, the limit pin 211 is in the limit slot 105, limiting the pressure buckle 200 to move only up and down and unable to rotate left and right, so as to ensure that the pressure beam 201 is aligned with the buckle rod 110. When the bolt 300 is rotated and tightened on the buckle seat 100, the pressure buckle 200 is pushed to be pressed on the buckle seat 100, so that the pressure beam 201 is pressed tightly on the buckle rod 110.

[0075] Compare with Figure 3 、 4 , Figure 3 This is one of the three-dimensional diagrams of the use state of one embodiment of the utility model. Figure 4 This is the second stereoscopic diagram of the use state of one embodiment of the utility model. Figure 3 、 Figure 4 Shows how to use this bolt-on fastener: Figure 3 As can be seen, when using a bolt-type fastener for sealing, the bag opening 401 is first passed from the bottom of the fastener base 100 through hole A101, around the fastener rod 110, and then out through hole B102. As can be seen, when the bolt 300 rotates on the fastener base 100, the pressure beam 201 is pressed against the fastener rod 110, thereby tightly pressing the bag opening 401 between the pressure beam 201 and the fastener rod 110, thereby sealing the soft bag or balloon 400.

[0076] We know that when the bag opening 401 passes through the hole A101 and then out of the hole B102, the bag opening is tightened and the width becomes smaller. It is wrapped around the buckle rod 110 in a multi-layer stacking form, so it is not flat. At this time, only the hard squeezing of the pressure beam 201 and the buckle rod 110 cannot achieve high air tightness. For this reason, we can improve the air tightness of the seal by adding high-elasticity padding.

[0077] comparison Figure 5 、 6 , Figure 5 This is a top exploded view of the second embodiment of the present invention. Figure 6 This is a bottom exploded view of the second embodiment of the present invention. This embodiment is basically the same as the first embodiment, the only difference is that Figure 5 It can be seen that a rubber pad 111 is added to the buckle rod 110. Figure 6 It can be seen that a pressure glue 202 is added to the pressure beam 201. The cushion glue 111 and the pressure glue 202 are flexible materials with high elasticity, such as rubber, silicone, etc. When the pressure beam 201 and the buckle rod 110 press the bag opening 401, the cushion glue 111 and the pressure glue 202 can adaptively deform the multi-layer stacked bag opening 401, and form a fully fitting and tight extrusion through the elasticity of the material, thereby achieving higher air tightness.

[0078] Compare with Figure 7 、 8 , Figure 7 This is a top exploded view of the third embodiment of the present invention. Figure 8 This is a bottom-up exploded view of the third embodiment of the present invention. This embodiment further improves the pressure beam 201 by designing a V-groove structure. This pressure beam 201 not only provides greater stability, but also provides a double squeeze on the bag opening through the V-groove A and V-groove B surfaces of the V-groove structure, achieving better sealing. Similarly, we can further enhance the sealing effect by adding rubber pads to the buckle rod 110 and the V-groove A and V-groove B surfaces.

[0079] In the above embodiments, the bag opening 401 must first pass through the hole A101 from the bottom of the buckle seat 100, bypass the buckle rod 110, and then pass through the hole B102. Obviously, since the openings of the holes A101 and B102 are not particularly large, this perforation method is not very convenient. For this reason, we can further improve it.

[0080] Compare with Figure 9 、 10 , Figure 9 This is a top exploded view of the fourth embodiment of the present invention. Figure 10 This is a bottom exploded view of the fourth embodiment of the present invention. Figure 9 、 Figure 10 It can be seen that in this embodiment, the buckle seat 100 is of open design, with a notch A103 on the outside of the hole A101 and a notch B104 on the outside of the hole B102. Obviously, such a design makes it very convenient to wrap the bag opening 401 around the buckle rod 110. If necessary, we can even wrap it a few more times to multiply the sealing effect.

[0081] Furthermore, the control Figure 9 、 Figure 10 It can also be seen that this embodiment also strengthens the buckle rod 110 and the pressure beam 201. The buckle rod 110 is designed to be square, and is designed with top teeth A112 and top teeth B114. It is also possible to further add a padding rubber A113 to the top teeth A112 and a padding rubber B115 to the top teeth B114. At the same time, pressure teeth A205, B207, and C209 are designed on the pressure beam 201. Similarly, it is also possible to further add a pressure glue A206 to the pressure tooth A205, a pressure glue B208 to the pressure tooth B207, and a pressure glue C210 to the pressure tooth C209. Figure 9 、 Figure 10 It can be seen that the top teeth A112, top teeth B114 and pressure teeth A205, pressure teeth B207, and pressure teeth C209 are staggered. When the pressure beam 201 is pressed against the buckle rod 110, the top teeth and the pressure teeth are in meshing state. The top teeth A112 correspond to the tooth groove between the pressure teeth A205 and the pressure teeth B207, and the top teeth B114 correspond to the tooth groove between the pressure teeth B207 and the pressure teeth C209. Thus, a staggered compression state is formed on the bag opening 401, thereby achieving a better airtight sealing effect.

[0082] Compare with Figure 11 , Figure 11 This is a perspective view of the fourth embodiment of the present invention. Figure 9 、 Figure 10 The exploded view shown is a perspective view of what it looks like when assembled.

[0083] In order to further meet the requirements of sealing the balloon, we can further reduce the diameter of the bolt-type buckle to make it miniaturized, lightweight and low-cost.

[0084] Compare with Figure 12 、 13 、14, Figure 12 This is a top exploded view of the fifth embodiment of the present invention. Figure 13 This is a bottom exploded view of the fifth embodiment of the present invention. Figure 14This is a three-dimensional diagram of the assembled state of the fifth embodiment of the present invention. This embodiment reduces the diameter of the buckle seat 100 as much as possible by eliminating the outer rotating ring of the buckle seat 100, thereby achieving miniaturization, lightness and low cost of the bolt-type buckle. In order to fix or rotate the buckle seat 100, the press buckle 200 is redesigned to form an elongated handle shape. Figure 14 It can be seen that the bolt 300 is hollow. When in use, the pressure beam 201 at the front end of the buckle 200 is combined with the buckle seat 100, and the limit pin 211 on the buckle 200 is located in the limit groove 105 on the buckle seat 100. The handle-shaped rear end of the buckle 200 passes through the hole in the middle of the bolt 300. In this way, the buckle seat 100 can be fixed or rotated by fixing or rotating the handle-shaped rear end of the buckle 200, thereby completing the rotational assembly of the bolt 300 and the buckle seat 100.

[0085] Compare with Figure 15 , Figure 15 This is a perspective view of the fifth embodiment of the present invention in use. This view shows the bolt-type closure of the fifth embodiment sealing a balloon 400. Using this bolt-type closure to seal a balloon offers significant advantages, such as convenience, speed, and excellent airtightness.

[0086] In the four embodiments described above, the buckle seat 100 is annular in shape. While this structure is simple, the length of the buckle rod 110 is relatively short, which means that there is insufficient space to seal a larger bag opening. Although the diameter of the buckle seat 100 can be increased, the resulting problem is that the overall volume is larger. Therefore, it is necessary to propose an embodiment using an elongated buckle seat 100 based on the technical principles of the above embodiments.

[0087] Compare with Figure 16 、 17 , 18, Figure 16 This is a three-dimensional diagram of the sixth embodiment of the present invention. Figure 17 This is a three-dimensional diagram of the sixth assembled state of the embodiment of the present utility model. Figure 18 This is an exploded view of the sixth embodiment of the present invention. The buckle seat 100 and the pressure buckle 200 of this embodiment are both long strips, with the thread 120 located in the screw hole 121 on the buckle seat 100. In this case, we can either use a shaft connection at one end and a tension bolt 300 at the other end to achieve a clip-like bag opening fastening; or, as shown in the figure, set a screw hole 121 and a bolt 300 at each end of the long strip seat buckle 100.

[0088] However, the design of the sixth embodiment has a drawback: when the buckle base 100 and the buckle 200 are long, when the buckle base 100 and the buckle 200 are not structurally strong enough, or when the bag opening is large and the bag is thick after folding, and the bolt 300 needs to exert a large force, the buckle base 100 and the buckle 200 used in this technical solution are prone to bending and deformation, resulting in poor airtightness or even failure. Therefore, further improvements are needed.

[0089] Compare with Figure 19 、 20 , 21, 22, 23, 24, 25, Figure 19 This is an exploded view from the upper left angle of the seventh embodiment of the present invention. Figure 20 This is a three-dimensional diagram of the assembly state of the seventh embodiment of the present invention from the upper left angle. Figure 21 This is a perspective view from the upper left side of the seventh embodiment of the present invention. Figure 22 This is an exploded view from the lower right side of the seventh embodiment of the present invention. Figure 23 This is a three-dimensional diagram of the assembly state of the seventh embodiment of the present invention from the lower right angle. Figure 24 This is a perspective view from the lower right side of the seventh embodiment of the present invention. Figure 25 This is a top view of the seventh embodiment of the present invention and a cross-sectional view of the corresponding cutting line. The buckle seat 100 and the buckle 200 of this embodiment are also long strips. The difference from the sixth embodiment is that the axis of the screw hole 121 in this embodiment is parallel to the long strip buckle seat 100, and there is an inclined arm 106 on the buckle seat 100. The angle between the inclined arm 106 and the buckle seat 100 is greater than 90 degrees. There is a slide groove 107 on the inclined arm 106; the buckle 200 is long strip and has the same length as the buckle seat 100 and adopts the same shape and structure as the buckle seat 100. A second screw hole 221 is designed on the buckle 200, and the axis of the second screw hole 221 is parallel to the buckle 200. 0 parallel, the second thread 220 is located in the second screw hole 221, the buckle 200 is also designed with a second oblique arm 222, the angle between the second oblique arm 222 and the buckle 200 is greater than 90 degrees, and the second oblique arm 222 is provided with a second slide groove 223; the screw rod 301 on the bolt 300 passes through the second slide groove 223 and cooperates with the screw hole 121, and the second screw rod 311 on the second bolt 310 passes through the slide groove 107 and cooperates with the second screw hole 221. After the above connection and cooperation, the buckle of this embodiment forms an oblique parallelogram structure. Figure 25It can be seen that since the screw hole 121 (for a simplified view, the thread line 120 in the screw hole 121 is not drawn) runs through the entire buckle seat 100, the second screw hole 221 (for a simplified view, the thread line 220 in the second screw hole 221 is not drawn) runs through the entire buckle 200, and at the same time, the screw rod 301 and the second screw rod 311 are almost the same length as the buckle seat 100 and the buckle 200 or slightly shorter (the slightly shorter scheme is drawn in each figure), when the screw rod 301 is rotated and tightened in the screw hole 121, a uniform pulling force is applied to various parts of the buckle rod 110 or the buckle beam 201, and deformation is not easy to occur. At this time, since the screw rod 301 passes through the second slide groove 223, the second The angle between the oblique arm 222 and the buckle 200 is greater than 90 degrees. Obviously, the bolt 300 will push the buckle 200 to slide in the direction of the buckle seat 100, thereby pressing the pressure beam 201 against the buckle rod 110; similarly, when the second screw 311 is rotated and tightened in the second screw hole 221, a uniform pulling force will be applied to all parts of the buckle 200 and it will not easily deform. At this time, since the second screw 311 passes through the slide groove 107, the angle between the oblique arm 106 and the buckle seat 100 is greater than 90 degrees. Obviously, the second bolt 310 will push the buckle seat 100 to slide in the direction of the buckle 200, thereby pressing the buckle rod 110 against the pressure beam 201, realizing two-way force.

[0090] Similarly, we can further design multiple top teeth on the buckle rod 110 of this embodiment, add rubber pads on the top teeth, design multiple pressure teeth on the pressure beam 201, add rubber pads on the pressure teeth, and design the top teeth and the pressure teeth to be staggered to form an interlaced and squeezed compression state on the bag opening, thereby achieving better airtight sealing and waterproof sealing effects.
