[0012] The using method of anti-theft zipper is: when using, the upper left chain cloth 25, the lower left chain cloth 27, the upper right chain cloth 26 and the lower right chain cloth 28 are connected with the mouth of the suitcase or the pocket of the luggage bag, and the handle 36 is positioned at Outside the luggage case or luggage bag; when the luggage case or luggage bag is closed, the handle 36 pulls the upper shell 15 or the lower shell 17 and the chain seat 1 to move, and the chain seat 1 moves with the handle 36, using the upper left chain groove of the chain seat 1 5 and the upper right chain groove 6 make the upper left chain 9 and the upper right chain 10 bite together; and utilize the lower left chain groove 7 and the lower right chain groove 8 of the chain seat 1 to make the lower left chain 11 and the lower right chain 12 bite together; put the luggage case At the same time, the upper steel tape 3 moves with the handle 36, and the upper steel tape 16 is pulled out as the upper steel tape 3 moves, and the pulled out upper steel tape 16 is locked by the left upper chain buckle 21 and the upper right chain buckle 22 are buckled on the upper chain plate 29; at the same time, the lower steel tape 4 moves with the handle 36, and the lower steel tape 18 is pulled out following the movement of the lower steel tape 4, and the pulled out lower steel tape 18 Buckle below the lower chain plate 33 by the lower left chain buckle 23 and the lower right chain buckle 24; Utilize the upper steel coil band 16 and the lower steel coil band 18 to seal the upper left chain 9 and the upper right chain 10 and the lower left chain 11 and the lower right chain 12 The occlusal opening increases the difficulty for criminals to use a sharp tool to insert the zipper; when opening the mouth of the suitcase or the pocket of the luggage bag, the chain seat 1 is pulled by the handle 36 to move in the opposite direction with the hand, and the chain seat 1 moves with the handle 36. The chain base 1 separates the engaged upper left chain 9 from the upper right chain 10, and separates the engaged lower left chain 11 from the lower right chain 12; at the same time, the upper steel tape measure 3 moves in the opposite direction with the handle 36, and the upper steel coil belt 16 moves in the upper steel The tape measure 3 is retracted in the upper steel tape measure 3 under the elastic force of the torsion spring of the tape measure 3;
[0013] When the anti-theft zipper closes the suitcase or luggage bag, the handle 36 pulls the chain seat 1 to move, the upper left chain 9 is introduced by the upper left chain slot 5 of the chain seat 1, and the upper right chain 10 is introduced by the upper right chain slot 6 of the chain seat 1. The left upper chain groove 5 and the right upper chain groove 6 of the seat 1 move to make the left upper chain buckle 21 and the right upper chain buckle 22 snap connected; The lower chain buckle 24 is engaged and connected; at the same time, the upper steel tape 3 moves with the handle 36, and the upper steel coil belt 16 is pulled out along with the movement of the upper steel tape 3. The hook 37 and the upper right horizontal hook 38 of the upper right chain buckle 22 are buckled on the upper chain plate 29; and the lower steel tape measure 4 moves with the handle 36, and the lower steel coil belt 18 is pulled out along with the lower steel tape measure 4. The lower steel coil belt 18 is fastened below the lower chain plate 33 by the lower left horizontal hook 39 of the lower left chain buckle 23 and the lower right horizontal hook 40 of the lower right chain buckle 24 .
[0014] In order to implement the upper steel coil band 16 and the lower steel coil band 18 to follow the handle 36 to move, the distance from the left corner lower part 41 of the left upper cross hook 37 to the right corner lower part 42 of the right upper cross hook 38 is greater than the width of the upper steel coil band 16, so that the upper steel coil band Tape 16 can move between left upper chain buckle 21 and right upper chain buckle 22; The steel coil belt 16 can move between the left lower chain buckle 23 and the right lower chain buckle 24; The upper chain plate 29 can move between the upper left chain buckle 21 and the upper right chain buckle 22; the inner width distance from the upper left corner 43 of the lower left horizontal hook 39 to the upper right corner 44 of the lower right horizontal hook 40 is greater than the width of the lower chain plate 33 , so that the lower chain plate 33 can move between the left lower chain buckle 23 and the right lower chain buckle 24 .
[0015]When the upper left chain buckle 21 and the upper right chain buckle 22 snap together, the distance between the upper left tail end 45 of the upper left horizontal hook 37 and the upper right tail end 46 of the upper right horizontal hook 38 is less than the width of the upper steel coil band 16, so that the upper steel coil band 16 is buckled under the upper left horizontal hook 37 and the upper right horizontal hook 38, so as to prevent the upper steel coil belt 16 from breaking away from the upper left horizontal hook 37 and the upper right horizontal hook 38; , the distance between the lower left tail end 47 of the lower left horizontal hook 39 and the lower right tail end 48 of the lower right horizontal hook 40 is less than the width of the lower steel coil band 18, so that the upper steel coil band 18 is buckled between the lower left horizontal hook 39 and the lower right horizontal hook 40 to prevent the lower steel tape 18 from detaching from the lower left hook 39 and the lower right hook 40; when the upper left chain 9 and the upper right chain 10 move and snap together, the upper steel tape 3 moves with the handle 36 and the chain seat 1 , the length of the upper steel coil belt 16 and the lower steel coil belt 18 drawn out is directly proportional to or equal to the length of the engagement and fastening of the upper left chain 9 and the upper right chain 10 .
[0016] When the upper left chain 9 and the upper right chain 10 are snapped together, the upper steel coil belt 16 is located between the upper chain plate 29, the upper left horizontal hook 37 and the upper right horizontal hook 38; the lower steel coil belt 18 is located between the lower chain plate 33 and the lower left lateral hook. Between the hook 39 and the lower right horizontal hook 40; when the upper left chain 9 and the upper right chain 10 are separated, the upper steel tape 3 and the lower steel tape 4 move in the opposite direction following the chain seat 1, and the upper steel coil belt 16 is recovered into the upper steel tape 3 The length of the length and the lower steel coil band 18 are recovered in the length of the lower steel tape measure 4 and the length that the upper left chain 9 separates from the upper right chain 10 is directly proportional or equal.
[0017] In order to reduce the moving resistance of the upper steel coil belt 16 and the lower steel coil belt 18, the upper guide wheel 34 is hinged with the upper housing 15 or the lower housing 17, and the lower guide wheel 35 is hinged with the lower chain plate 33; When the tape measure 3 was pulled out, the upper steel coil belt 16 pressed the upper guide wheel 34, and the upper steel coil belt 16 drove the upper guide wheel 34 to rotate, reducing the friction between the upper steel coil belt 16 and the upper guide wheel 34; 18 pushes down guide wheel 35, and lower steel coil band 18 drives lower guide wheel 35 to rotate, reduces the frictional force of lower steel coil band 18 and lower guide wheel 35; Coil belt 16 pushes down upper guide wheel 34, and last steel coil belt 16 drives upper guide wheel 34 to rotate, reduces the frictional force of upper steel coil belt 16 and upper guide wheel 34; The steel coil belt 18 drives the lower guide wheel 35 to rotate, reducing the friction between the lower steel coil belt 18 and the lower guide wheel 35.
[0018] In order to lock the chain base 1 with a lock, the upper shell 15 or the lower shell 17 is provided with a dynamic lock hole 49, and the chain tail sealing part 14 is provided with a fixed lock hole 50, so that the chain base 1 and the chain tail sealing part 14 can be connected conveniently with a lock. locked together.
