Detailed Description

The following describes embodiments of the present invention with reference to the drawings.

Reference is made to fig. 1, 2, 3, 4, 5, 6, 7, 8 and 9. A chain tooth of an explosion-proof zipper comprises a tooth head 1 and a tooth body 2 which are respectively positioned at the left side and the right side, wherein the tooth head 1 and the tooth body 2 are in transitional connection through a tooth neck 3, the upper side and the lower side of the tooth head 1 are respectively provided with a convex part 4, and the upper side and the lower side of the tooth neck 3 are respectively provided with a concave part 5; when two adjacent upper and lower elements are engaged with each other, the protruding portion 4 of any one element can be sunk into the recessed portion 5 of the other element, and has a mutual abutting force with the neck 3 of the other element. Through setting up bellying 4 and depressed part 5 for when two chain teeth mesh, bellying 4 can exert the effort to tooth neck 3, thereby make not only have vertical engaging force between the chain tooth, still have horizontal engaging force, improved the intensity when the chain tooth meshes greatly, effectively avoid appearing the phenomenon of bursting that the chain tooth is thrown off.

In particular, the following two embodiments are provided,

example one

Refer to fig. 1, 2, 3, and 4. The upper and lower end surfaces 31 of the tooth neck 3 are connected with the tooth head side surfaces and the tooth body side surfaces on the left and right sides to form a groove 6 corresponding to the upper and lower sides of the tooth head 2; the upper side and the lower side of the tooth head 2 are symmetrical.

Refer to fig. 1, 2, 3, and 4. The groove 6 is trapezoidal and gradually widened from the tooth neck end face 31 to the outside; the recessed portion 5 is also trapezoidal and is tapered inward from the neck end surface 31, and the protruding portion 4 corresponds to the recessed portion 5.

Refer to fig. 1, 2, 3, and 4. The concave part 5 arranged on the upper side of the tooth neck is positioned at the rear part of the tooth neck 3, and the convex part 4 arranged on the upper side of the tooth head 1 is positioned at the rear part of the tooth head 1; the concave part arranged at the lower side of the tooth neck is positioned at the front part of the tooth neck, and the convex part arranged at the upper side of the tooth head is positioned at the front part of the tooth head. Through front and back staggered arrangement, can guarantee that the meshing back of chain tooth, meet the external force of any direction, the meshing of chain tooth can not destroyed to play the explosion-proof effect.

Example two

Refer to fig. 5, 6, 7, 8 and 9. The upper and lower end surfaces 31 of the tooth neck 3 are connected with the tooth head side surfaces and the tooth body side surfaces on the left and right sides to form a groove 6 corresponding to the upper and lower sides of the tooth head 2; the upper side and the lower side of the tooth head 2 are symmetrical.

Refer to fig. 5, 6, 7, 8 and 9. The groove 6 is roughly trapezoidal and gradually widened outwards from the tooth neck end face 31; the recess 5 is also substantially trapezoidal and tapers inwardly from the neck end face 31, and the protrusion 4 corresponds to the shape of the recess 5.

Refer to fig. 5, 6, 7, 8 and 9. The concave part 5 arranged on the upper side of the tooth neck is positioned at the rear part of the tooth neck 3, and the convex part 4 arranged on the upper side of the tooth head is positioned at the front part of the tooth head; the concave part arranged at the lower side of the tooth neck is positioned at the front part of the tooth neck, and the convex part arranged at the upper side of the tooth head is positioned at the rear part of the tooth head.

Refer to fig. 5, 6, 7, 8 and 9. A convex column 7 is arranged in the groove 6, the convex column 7 is positioned on the right side surface of the tooth body 2, and a column groove 8 matched with the convex column 7 is arranged on the right side surface of the tooth head 1; when two adjacent upper and lower chain teeth are mutually engaged, the convex column 7 is inserted into the corresponding column groove 8, so that the transverse engaging force between the chain teeth is further improved.

In addition, the convex columns and the column grooves can also be applied to the first embodiment; in addition, the groove in the first embodiment may be substantially trapezoidal, and the groove in the second embodiment may be trapezoidal.
