Description

Technical Field

[0001] The utility model belongs to the technical field of tube strips, and in particular relates to a double-layer tube strip with hidden seams. Background Art

[0002] A suitcase is a box that people carry with them when they go out to store items. Usually, a suitcase is used to store clothes, personal care products and souvenirs needed for the journey.

[0003] There are many materials for suitcases, such as hard plastic or aluminum alloy. The suitcase is made of two concave shells connected together. In order to facilitate the loading of items, the lining is sewn inside the shell, and a bag is installed on the lining. At the same time, the edges of the two shells are sewn with zippers, which are bitten together by the zipper. At present, in order to achieve the sewing and fixing of the lining, shell and zipper, a tube strip is added as an intermediate piece, but the existing tube strip is a U-shaped structure. The U-shaped tube strip is set on the edge of the shell, and the remaining lining and zipper are stacked and fixedly connected by stitching. The three-way connection structure sewn by the U-shaped tube strip is not strong enough. At the same time, the stitching is exposed outside, which affects the appearance and looks uneven.

[0008] The edge of the lining is inserted into the first card slot, and the edge of the box shell is inserted into the first card slot, and the lining and the box shell are stacked; the edge of the zipper cloth is inserted into the second card slot;

[0009] The sewing thread passes through the first fixing strip, the lining, the box shell, the second fixing strip and the zipper cloth to connect and fix them.

[0010] On the basis of the above scheme and as a preferred scheme of the above scheme: the bottom edge of the first gear bar protrudes from the first fixing bar, and the top edge of the first gear bar protrudes from the third fixing bar.

[0011] On the basis of the above solution and as a preferred solution of the above solution: the outer edge of the second fixing strip protrudes outward to form a second stop strip.

[0012] On the basis of the above solution and as a preferred solution of the above solution: the outer end of the third fixing strip is bent toward the zipper cloth to form a bent strip.

[0013] On the basis of the above solution and as a preferred solution of the above solution: an outer surface of the bent strip is provided with a curved surface.

[0014] Compared with the prior art, the utility model has the following outstanding and beneficial technical effects:

[0015] Compared with the prior art, the double-layer tube strip with hidden stitches of the utility model comprises a first stop strip, a first fixing strip and a second fixing strip protrude from the first stop strip, the three of which together form a first slot, the edges of the lining cloth and the box shell are stacked and inserted into the first slot; a third fixing strip protrudes from the first stop strip, the second fixing strip and the third fixing strip together form a second slot, the edge of the zipper cloth is inserted into the second slot, the lining cloth, the box shell, the tube strip and the zipper cloth are sewed and fixed by sewing threads respectively, and the firmness is strong.

[0019] The present invention will be further described below with reference to specific embodiments of the invention;

[0020] This embodiment provides a double-layer tube strip with hidden stitches, including a long tube strip 01, which is formed by extrusion of elastic material and can be compressed and restored. The length of the tube strip 01 is cut according to the requirements of the matching suitcase; the cross section of the tube strip 01 includes a first stop bar 010 arranged on the outside, and the same side surface of the first stop bar 010 protrudes from the inside to the outside with a first fixing bar 011, a second fixing bar 012 and a third fixing bar 013; the widths of the three fixing bars are designed accordingly according to the selected width; the first fixing bar 011 is placed inside the box shell 03, and the third fixing bar 013 is placed outside the box shell 03;

[0021] The first fixing bar 011 and the second fixing bar 012 together form a first card slot 0110, and the second fixing bar 012 and the third fixing bar 013 together form a second card slot 0130; the first card slot 0110 and the second card slot 0130 are long strip-shaped slots;

[0022] The edge of the lining 02 is inserted into the first card slot 0110, and the edge of the box shell 03 is inserted into the first card slot 0110, and the lining 02 and the box shell 03 are stacked; the edge of the zipper fabric 04 is inserted into the second card slot 0130;

[0023] The sewing thread 05 passes through the first fixing strip 011, the lining 02, the box shell 03, the second fixing strip 012 and the zipper fabric 04 to connect and fix.

[0024] As described above, the specific sewing process is to piece together the lining 02 and the inner surface of the box shell 03, insert them into the first slot 0110 of the tube strip 01 at the same time, and then insert the zipper cloth 04 into the second slot 0130, and use a sewing machine to pass the sewing thread 05 through the first fixing strip 011, the lining 02, the box shell 03, the second fixing strip 012 and the zipper cloth 04 to connect and fix them; the sewing machine can set the sewing depth of the sewing thread 05.

[0025] The lining 02 and the box shell 03 are fixed in the first card slot 0110, and the zipper cloth 04 is fixed in the second card slot 0130, and the fixing is more firm. At the same time, the third fixing strip 013 can cover the sewing line 05 to achieve a hidden effect, making the product look smoother and more beautiful.

[0026] Furthermore, a first fixing bar 011 protrudes from a bottom edge of the first block bar 010 , and a third fixing bar 013 protrudes from a top edge of the first block bar 010 .

[0027] As described above, the first fixing strip 011 and the third fixing strip 013 protrude from the bottom and the top of the first gear strip 010 respectively, which facilitates mold extrusion production and makes the tube strip 01 more smooth and beautiful.

[0028] Furthermore, the outer edge of the second fixing bar 012 protrudes outward to form a second stop bar 0120 .

[0029] As described above, the second stop bar 0120 blocks the zipper fabric 04 from running out, and has a blocking effect during the use of the sewing machine;

[0030] Furthermore, the outer end of the third fixing strip 013 is bent toward the zipper cloth 04 to form a bent strip 0131 .

[0031] As mentioned above, the bent strip 0131 has the function of pressing the zipper fabric 04;

[0032] Furthermore, an outer surface of the bent strip 0131 is provided with a curved surface 0132 .

[0033] As mentioned above, the arc surface 0132 serves to prevent mistakes in the installation of the tube strip 01 .
