Background technique

At present, the zipper used in the trunk or duffel bag, due to the insufficient strength of the zipper, can be used to insert the zipper into the zipper during the use process, and the zipper can be opened, and a double-roll double-layer protection against the zipper is prevented. The use of the zipper has become a need to increase the strength of the zipper and theft.

Summary of the invention

The object of the present invention is to overcome the deficiencies of the prior art and to provide a method for using a double-volume double-layer anti-insertion zipper for improving the zipper strength and improving the anti-theft performance of the zipper.

The technical solution adopted by the invention is that the double-roll double-layer anti-insertion zipper comprises a chain seat, an upper chain, a lower chain and a steel tape measure, and the steel tape measure comprises an upper steel tape measure and a lower steel tape measure, the chain seat and the upper chain and the lower chain. And a steel tape measure shell connection; the chain seat has a left upper chain groove, an upper right chain groove, a left lower chain groove and a lower right chain groove, the upper chain includes an upper left chain, an upper right chain, a chain head sealing member, and a chain tail sealing member, the lower chain The utility model comprises a lower left chain and a lower right chain, the upper left chain, the upper right chain, the lower left chain and the lower right chain are connected with the chain sealing member and the chain tail sealing member; the upper left chain is connected with the upper left chain slot, the upper right chain is connected with the upper right chain slot, and the lower left chain is connected to the lower left chain slot. The chain and the lower left chain slot, the lower right chain and the lower right chain slot; the upper left chain has an upper left chain buckle and a left upper chain cloth, the upper left chain buckle is connected with the left upper chain cloth, and the upper left chain buckle is provided with a left anti-insert piece and a left upper chain hook. The upper left buckle, the left anti-insert tab and the upper left chain hook are made of one piece of material; the upper right chain has an upper right chain buckle and an upper right chain cloth, the upper right chain buckle is connected with the upper right chain cloth, and the upper right chain buckle is provided. Right anti-insert and right upper chain hook, right upper cuff, right anti-insert and right upper chain hook are made of one piece of material; left lower chain has left lower cuff and left lower chain cloth, left lower cuff is connected with left lower chain, left lower chain The buckle has a left lower chain hook, the lower left chain buckle and the left lower chain hook are made of one piece of material; the lower right chain has a lower right chain buckle and a lower right chain cloth, the lower right chain buckle is connected with the right lower chain cloth, and the lower right chain buckle The right lower chain hook is provided, and the lower right chain buckle and the lower right chain hook are composed of an integral material; the upper steel tape measure is provided with an upper steel coil, and the upper end of the upper steel coil is connected with the chain head sealing member of the upper chain, The steel reel is connected with the upper left chain hook and the upper right chain hook, on the upper The steel reel is located above the chain seat; the lower steel tape is provided with a lower steel reel, the lower end of the lower steel reel is connected with the chain sealing member of the upper chain, and the lower steel reel is hooked with the lower lower chain and the lower lower chain With the connection, the lower steel coil is located below the chain seat; the left anti-insert is located between each upper left cuff, and the right anti-insert is located between each upper right cuff, using the left anti-insert and right The anti-insert seals the gap between the upper left buckle and the upper right buckle, which increases the difficulty of inserting the illegal chain into the upper chain; when the criminal uses the sharp weapon to insert the upper chain and the current chain, the sharpener is wound on the steel strip and the lower steel coil Blocking, making it difficult for criminals to insert the upper chain and the lower chain.

The double-volume double-layer anti-sliding zipper is used by connecting the left upper chain cloth, the left lower chain cloth, the upper right chain cloth and the lower right chain cloth to the trunk of the luggage box, and the handle on the steel tape measure is located in the trunk. When the suitcase is closed, the hand gripper pulls the steel tape measure and the chain seat moves, and the chain seat follows the handle movement, so that the upper left chain and the upper right chain are snapped together, and the left lower chain and the lower right chain are snapped together. The box mouth of the suitcase is closed; the upper steel tape measure moves along the chain seat, and the upper steel coil is pulled out with the movement of the upper steel tape measure, and the upper steel coil is pulled by the upper left chain hook and the upper upper chain hook in the chain seat. Above, the upper left chain and the upper right chain are closed; at the same time, the lower steel tape is moved following the chain seat, and the lower steel tape is pulled out with the lower steel tape moving, and the pulled lower steel tape is pulled by the left lower chain hook. The lower right chain hook is fastened under the chain seat, and the left lower chain and the lower right chain are closed; when the upper left chain and the upper right chain are closed, the left anti-insert is moved to be located in one upper left cuff and the other upper left cuff. Location, and The anti-insert is moved to a position between one upper right cuff and the other upper right cuff, and the left anti-insert is used to block the gap between one upper left cuff and the other upper left cuff, and the right anti-insert is used to block an upper right chain. The gap between the buckle and the other right upper clasp increases the difficulty for the criminals to use the sharpener to open the zipper; when opening the trunk of the trunk, the handle is moved in the opposite direction by the handle by hand, and the chain base follows the handle to make the closure The upper left chain is separated from the upper right chain, and the left lower chain and the lower right chain are closed; at the same time, the upper steel coil moves in the opposite direction of the chain seat, and the upper steel coil retracts the upper steel under the elastic force of the upper steel coil torsion spring. Inside the tape measure; and the lower steel coil is moved in the opposite direction of the chain seat, and the lower steel coil is taken back under the elastic force of the lower steel coil torsion spring.

The utility model has the beneficial effects that: when used, the double-roll double-layer anti-insert zipper is arranged on the luggage box, and the double-roll double-layer anti-plug zipper is provided with an upper chain, a lower chain, an upper steel tape measure and a lower steel tape measure, and the upper chain is provided. There is a left anti-insert and a right anti-insert, and the left anti-insert and the right anti-insert are used to seal the gap between the left and right clasps, and the upper steel strip and the lower steel reel are used to seal the upper chain and The lower chain, when the criminals use the sharp weapon to insert the upper chain and the lower chain, increase the use of the weapon The difficulty of inserting the zipper.
