Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides a draw zipper head, including film 1, top piece 4 and pulling-on piece 7, the centre of film 1 and pulling-on piece 7 is provided with connects casing 2, and film 1 and pulling-on piece 7 all have welded swash plate 11 near one side of connecting casing 2, the table wall in the vertical direction of two equal through connection casings 2 of swash plate 11, and with connect through 15 elastic connection of second spring between the table wall in the vertical direction of casing 2, second spring 15 gives swash plate 11 one to the elasticity that is close to of connecting casing 2 center department, the center department of table wall is rotated through the pivot in the horizontal one side of connecting casing 2 near pulling-on piece 7 is connected with threaded rod 14, the outside of threaded rod 14 closes soon and is connected with thread bush 12, when threaded rod 14 rotates, thread bush 12 shifts on the horizontal direction.

Specifically, as shown in fig. 5, rollers 13 are mounted at both vertical ends of the threaded sleeve 12, and the rollers 13 can roll on the swash plate 11.

Specifically, as shown in fig. 5, the threaded rod 14 penetrates through the inner surface wall of the horizontal side of the connecting shell 2 away from the pull tab 7 and is fixedly connected with the knob 3 arranged outside the connecting shell 2, and the knob 3 facilitates rotation of the threaded rod 14.

Specifically, as shown in fig. 1 and 2, fixed blocks 5 are welded to both sides of the center of the upper end surface of the top plate 4, the fixed blocks 5 are connected with a moving block 6 in a sliding manner on the inner surface wall of one side close to the center of the top plate 4, the moving block 6 is elastically connected with the inner surface wall of one side of the fixed blocks 5 far away from the center of the top plate 4 through a first spring 10, and the first spring 10 gives the moving block 6 an elastic force close to the center of the top plate 4.

Specifically, as shown in fig. 2, a limiting sleeve 9 welded on the inner surface wall of the bottom of the fixed block 5 is sleeved outside the moving block 6, and the limiting sleeve 9 prevents the moving block 6 from deviating in the process of moving in the horizontal direction.

Specifically, as shown in fig. 2, the limiting blocks 8 are welded at the two vertical ends of the moving block 6 located in the inner cavity of the fixing block 5, and the limiting blocks 8 prevent the moving block 6 from being separated from the fixing block 5.

The working principle is as follows: when in use, when the zipper puller clamps cloth, the knob 3 is rotated, the threaded rod 14 is rotated by the rotation of the knob 3, the threaded rod 14 is rotated, so that the threaded sleeve 12 moves in the horizontal direction of the threaded rod 14, during the movement of the threaded sleeve 12 in the horizontal direction of the threaded rod 14, the roller 13 and the sloping plate 11 roll relatively, the sloping plate 11 drives the top sheet 4 and the bottom sheet 1 to move towards the direction far away from the connecting shell 2 respectively in the rolling process of the roller 13, the top sheet 4 and the bottom sheet 1 move towards the direction far away from the connecting shell 2, so that the clamped cloth can be separated from the zipper puller, compared with the traditional zipper puller which is integrally formed, the zipper puller is more convenient, when the pull piece 7 needs to be replaced, the pull piece 7 is pulled out from the joint of the two moving blocks 6, and the new pull piece 7 is pressed to the joint of the two moving blocks 6, so that the new pull piece 7 can be installed.
