Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-3 is please referred to, the utility model provides a kind of technical solution：A kind of injection molding square, including shell 1, side snap-gauge 4
With outer casing inner wall 10, the positioned beneath of shell 1 has right sealing plate 2, and the left side of shell 1 is equipped with side connecting plate 3, side snap-gauge 4
Lower left is provided with recess inner wall 5, and side snap-gauge 4 is located at the left side of side connecting plate 3, and the right side of recess inner wall 5 is equipped with recessed
Mouthful outer wall 6, and the bottom end of recess inner wall 5 is mounted with ramp 7, side snap-gauge 4 are " recessed " word structure, and recess inner wall 5 and recess
Outer wall 6 is symmetrically distributed with 2 by the vertical centerline of side snap-gauge 4, and " recessed " word structure of side snap-gauge 4 makes the strap of zipper
It can be stuck in the snap-gauge of side, fixed function can be played to zipper, the lower section of ramp 7 is connected with lower inclined plane 8, and lower inclined plane
8 lower section is equipped with left sealing plate 9, and arc structure, and ramp 7, lower inclined plane 8 and recess are constituted between ramp 7 and lower inclined plane 8
Inner wall 5 is structure as a whole, and makes the plug of zipper cause abrasion to reduce strap, avoiding the destructurized of strap leads to strap
Fluffing, to enhance the service life of zipper, the right side of left sealing plate 9 is provided with outer casing inner wall 10, and the bottom of outer casing inner wall 10
End is mounted with opening 11, and the bottom of shell 1 constitutes opening 11, and 2 medial surface of right sealing plate and a left side by right sealing plate 2 and left sealing plate 9
The distance between 9 medial surface of sealing plate is greater than the distance between 5 medial surface of recess inner wall, and the thickness of bolt is greater than the thickness of strap,
Block strap when bolt insertion opening 11 by the opening of relatively narrow side snap-gauge 4, the lower section of inner prop 12 is connected with column jacket 13,
And inner prop 12 is located at the right end of outer casing inner wall 10, surface is bonded between inner prop 12 and column jacket 13, and between inner prop 12 and column jacket 13
Area is identical, and the area of inner prop 12 is the 45% of 1 area of shell, the sum of area volume of inner prop 12 and column jacket 13 and bolt
Identical, bolt is attached by opening 11 with shell 1, and the groove coincideing with 14 size of fixture block, column jacket are provided on bolt
Fixture block 14 is installed on the left of 13 bottom end, and the bottom end surface of column jacket 13 is provided with card slot 15, the top of shell 1 is equipped with bottom
Sealing plate 16, shell 1 are hollow structure, and shell 1 and right sealing plate 2, side connecting plate 3, the left sealing plate 9 of side snap-gauge 4 and bottom sealing plate 16
