Detailed Description

The utility model is further illustrated by the following figures and examples, which are not to be construed as limiting the utility model.

Examples are given. An anti-explosion zipper with rubber teeth is formed as shown in figures 1 to 6 and comprises a first cloth strip 1 and a second cloth strip 2 which are symmetrically distributed, wherein a plurality of rubber teeth 3 which are uniformly distributed are arranged on the first cloth strip 1 and the second cloth strip 2; the middle part of each rubber tooth 3 is provided with an installation cavity 4, and an iron block 5 is arranged in each installation cavity 4; all the rubber teeth 3 are arranged between the first cloth strip 1 and the second cloth strip 2, and a first magnet 6 is arranged between every two adjacent rubber teeth 3; a first lower stop piece 7 is fixedly arranged at the bottom end part of the side wall of the first cloth strip 1 facing the second cloth strip 2, and a plurality of uniformly distributed bulges 8 are arranged on the surface of each first lower stop piece 7; a second lower stopping piece 9 is fixedly arranged at the bottom end part of the side wall of the first cloth strip 1 on the second cloth strip 2, and an L-shaped groove 10 for clamping the first lower stopping piece 7 is formed in the side surface of the second lower stopping piece 9 facing the first cloth strip 1; a slider 11 which is slidably mounted on the second cloth strip 2 is arranged above the second lower stop 9.

A first upper stop piece 12 is arranged at the top end part of the side wall of the first cloth strip 1 facing the second cloth strip 2, and a second magnet 13 is arranged on the top surface of the first upper stop piece 12; a second upper stop piece 14 is arranged at the top end part of the side wall of the first cloth strip 1 on the second cloth strip 2, and a second magnet 13 is also arranged on the top surface of the second upper stop piece 14; the top end part of the pull head 11 is sleeved with an inverted U-shaped limiting piece 15, and an iron sheet 16 matched with the second magnet 13 is arranged on the inner top surface of the limiting piece 15; a connector 17 is slidably mounted on the limiting member 15, and a pulling member 18 for pulling the slider 11 to move is fixedly mounted on the connector 17; the surface of the pulling part 18 is provided with a plurality of evenly distributed anti-skid projections 19; the top end parts of the two side surfaces of the pull head 11 are respectively provided with two symmetrically arranged cloth blocking pieces 20.

The working principle is as follows: when the cloth is used, the first lower stop piece 7 on the first cloth strip 1 penetrates through a channel on the slider 11 and is clamped into the L-shaped groove 10 on the second lower stop piece 9, and because the surface of the first lower stop piece 7 is provided with a plurality of uniformly distributed bulges 8, the friction force between the first lower stop piece 7 and the second lower stop piece 9 can be increased by utilizing the bulges 8, so that the connection stability between the first lower stop piece 7 and the second lower stop piece 9 can be increased, the phenomenon that the first lower stop piece 7 is separated from the second lower stop piece 9 is avoided, and the use stability is improved; then, according to the operation mode of closing the common zipper, the pulling piece 18 is pulled to move upwards, so that the pulling piece 18 drives the whole zipper head 11 to move towards the first upper stop piece 12 and the second upper stop piece 14 through the connecting head 17 and the limiting piece 15; along with the upward movement of the slider 11, the glue teeth 3 on the first cloth strip 1 and the second cloth strip 2 are neatly arranged in a staggered manner under the action of a combining channel in the slider 11, and in the arrangement process of the glue teeth 3, the position of the glue teeth 3 on the first cloth strip 1 or the second cloth strip 2 corresponds to the position of the first magnet 6 on the second cloth strip 2 or the first cloth strip 1, at the moment, the first magnet 6 generates an attraction force on an iron block in the glue teeth 3, so that the first magnet 6 can pull the first cloth strip 1 or the second cloth strip 2 to move towards the second cloth strip 2 or the first cloth strip 1 while fixing the position of the glue teeth 3, thereby enabling the first cloth strip 1 and the second cloth strip 2 to be close to each other, and enabling the self clamping force between the glue teeth 3 and the glue teeth 3 to achieve the maximum degree of the connecting force between all the glue teeth 3 between the first cloth strip 1 and the second cloth strip 2, the phenomenon that the zipper bursts in the using process can be avoided, and the anti-explosion effect of the zipper is improved; meanwhile, in the moving process of the pull head 11, the pull head 11 can drive the cloth blocking piece 20 to move together, and the cloth blocking piece 20 can be used for pushing the surrounding cloth open in advance, so that the phenomenon that the cloth is clamped between the rubber teeth 3 and the rubber teeth 3 in the pulling and closing process is avoided; when the slider 11 is pulled to the positions of the first upper stop 12 and the second upper stop 14, at this time, the first upper stop 12 and the second upper stop 14 are firstly drawn together under the action of the slider 11, so that the top surfaces of the first upper stop 12 and the second upper stop 14 are upwards inserted between the limiting part 15 and the slider 11, and at this time, under the action of attraction force between the second magnet 13 and the iron sheet 16, the top surfaces of the first upper stop 12 and the second upper stop 14 can be attached to the inner top surface of the limiting part 15, so that the slider 11 can be limited from continuously moving upwards, the position of the slider 11 can be fixed, and the phenomenon that the zipper is pulled open due to the fact that the slider 11 moves downwards in the subsequent pulling and closing use process is avoided; when the pulling member 18 needs to be hidden, the pulling member 18 can be moved from one side to the other side of the slider 11 by moving the pulling member 18 along the stopper 15.
