CONCRETE IMPLEMENTING METHOD

[0021] Referring to the accompanying Figure 1 It is the utility model structural schematic diagram. A kind of packaging based on mechanics design and space folding, including first cover 1, second cover 2, first cover 1, second cover 2 and band 3 are formed without splicing from the same piece of flexible material, this embodiment adopts cowhide as the flexible material, first cover 1 and second cover 2 are folded and sewed and form cavity, this cavity is used to place card.

[0022] In the upper part of the first envelope 1, a second belt passing hole 5 is arranged, and the belt 3 is arranged in the upper part of the second envelope 2. The belt 3 is in a belt shape, and the belt 3 can be wrapped or curled.

[0023] In the upper part of the second envelope 2 and the lower part of the belt 3, a first belt passing hole 4 is arranged. After the first envelope 1 and the second envelope 2 are folded, the first belt passing hole 4 and the second belt passing hole 5 form a through hole, which is used for the belt 3 to pass through. The so-called through hole can also be called alignment.

[0024] The belt 3 is further provided with a first connecting hole 6, a second connecting hole 7, and a third connecting hole 8. The third connecting hole 8 is located in the lower part of the belt 3, and the first connecting hole 6 is located in the upper part of the belt 3. The second connecting hole 7 is arranged between the first connecting hole 6 and the third connecting hole 8. After the belt 3 passes through the second belt passing hole 5 and the first belt passing hole 4 in sequence, the top end of the belt 3 can be extended upward, and in this state, the first connecting hole 6 and the second connecting hole 7 are located on both sides of the third connecting hole 8.

[0025] Further, the width of the first belt passing hole 4 and the second belt passing hole 5 is smaller than the width of the belt 3, and the belt 3 is provided with a limiting and shaping groove 11. After the belt 3 passes through the second belt passing hole 5 and the first belt passing hole 4 in sequence, the limiting and shaping groove 11 is used for embedding the first envelope 1 and the second envelope 2. The first connecting hole 6 and the second connecting hole 7 are located on both sides of the limiting and shaping groove 11, and the distance between the first connecting hole 6 and the second connecting hole 7 and the limiting and shaping groove 11 is equal.

[0026] Further, the number of limiting and shaping grooves 11 is two, and the two limiting and shaping grooves 11 are located on both sides of the belt 3 and are symmetrically arranged.

[0027] If there is no limiting and shaping groove 11, the belt 3 is easy to form wrinkles after passing through the first belt passing hole 4 and the second belt passing hole 5, and the distance between the belt 3 and the first belt passing hole 4 and the second belt passing hole 5 may change, which is easy to cause deformation of the first envelope 1, the second envelope 2, and the belt 3, which is not beautiful.

[0028] Further, the top end of the first envelope 1 is further provided with an extension piece 13, which is located above the second belt passing hole 5, and the extension piece 13 and the first envelope 1 are made of the same flexible material without splicing. The role or effect of the extension piece 13 is that the distance between the second belt passing hole 5 and the top end of the first envelope 1 is close, so that after long use, there is a risk of breaking above the second belt passing hole 5. Therefore, an extension piece 13 is arranged to increase the strength and reduce the risk of breaking.

[0029] Further, the extension piece 13 is provided with a fourth connecting hole 12, and the first connecting hole 6, the second connecting hole 7, the third connecting hole 8, and the fourth connecting hole 12 are through.

[0030] Further, a metal ring is provided for passing through the first connecting hole 6, the second connecting hole 7, the third connecting hole 8 and the fourth connecting hole 12. With the metal ring, the opening of the device can be securely locked, and the metal ring can be conveniently connected with a key bag or a key chain.

[0031] After folding, the sewing line 9 forms an L shape with the first cover 1 or the second cover 2. If the card is generally rectangular, the device only needs to be sewn in the L shape to realize the function of accommodating the card.

[0032] The metal ring directly suspends the second cover 2. If there is no fourth connecting hole 12, the metal ring cannot directly suspend the first cover 1, and long-term use will cause the first cover 1 to deform, especially around the second belt hole 5, forming wrinkles, which is not beautiful. Therefore, the fourth connecting hole 12 plays an important role in preventing the device from deforming during long-term use.

[0033] The use method of the utility model is as follows: first, a flexible material such as leather is used to complete the cutting of the material at one time, splicing is not required, and stamping or laser cutting can be used. Such design greatly reduces the manufacturing process. Then, fold along the folding line 10. It should be noted that the folding line 10 is not an actual component of the device. After folding, sew the two edges to form a cavity for accommodating the card with the first cover 1 and the second cover 2.

[0034] Next, the end of the belt 3 is inserted into the second belt hole 5, then through the first belt hole 4, and then the end of the belt 3 is pulled upwards. At this time, the first connecting hole 6, the second connecting hole 7, the third connecting hole 8 and the fourth connecting hole 12 are penetrated, and then the metal ring is passed through the penetrated hole, thereby completing the packaging of the card.

[0035] It should be noted that further, the distance from the first connecting hole 6 to the limiting and shaping groove 11 is equal to the distance from the second connecting hole 7 to the limiting and shaping groove 11, and also equal to the distance from the fourth connecting hole 12 to the second belt hole 5. The three distances are equal, which is very important. Because of such design, uniform stress can be achieved, and the device can be used for a long time without deformation or wrinkles, thereby maintaining a good shape for a long time.

[0036] The limiting and shaping groove 11 is a notch provided on the belt 3. The notch can hold the first cover 1 and the second cover 2, and the belt 3 cannot be displaced, so that the belt 3 is not easily deformed. If the belt 3 is displaced, the first cover 1 and the second cover 2 are easily deformed under the action of friction. Since the device is usually made of leather, the belt 3 is difficult to return to the appropriate position without the limiting and shaping groove 11. It should be noted that the friction is generated by the belt 3 and the first belt hole 4 and the second belt hole 5.

[0037] Because the device is made of the same piece of leather without splicing, it needs to be folded and sewn. For the convenience of description, the application uses such expressions as folding line 10 and sewing line 9. In fact, the folding line 10 and the sewing line 9 are not components of the device. Those skilled in the art should know that the first cover 1 and the second cover 2 need to be sewn along the sewing line 9 with a strong thread.

[0038] The part of the first cover 1 and the second cover 2 except the sewing line 9 is called the effective cover, or the area surrounded by the sewing line is called the effective cover. The band 3 is located in the middle of the effective cover of the second cover 2, the extension piece 13 is located in the middle of the effective cover of the first cover 1, the first connecting hole 6, the second connecting hole 7, the third connecting hole 8 and the first perforated band are located on the same straight line, which is parallel to the folding line 10.

[0039] In order to make the band 3 more solid and not easy to break from the second cover 2, a transition part 14 can be provided.

[0040] The first belt hole 4 and the second belt hole 5 have the same width, which is equal to the width of the band 3 at the position of the limiting and shaping groove 11.

[0041] The utility model also solves three technical problems: 1. The manufacturing process is simple, and only one stamping is needed to complete the preparation. 2. The risk of loosening is greatly reduced, the card will not fall in the device, and the device is easy to connect with a key ring or a wristband, and the device itself is not easy to fall off. 3. The rigorous mechanical design makes the device can be used for a long time without deformation and wrinkles, keeping the appearance beautiful.
