Description

Technical Field

[0001] The utility model relates to the technical field of oxygen chamber zippers, in particular to an easy-to-pull non-linear zipper and a flexible oxygen chamber. Background Art

[0002] In a flexible hyperbaric oxygen chamber, the door is closed with a zipper. To facilitate entry and exit, the door is often made into non-linear shapes such as U-shape, C-shape, and L-shape. Since the cabin skin material is relatively hard, the zipper head is often blocked when the zipper is pulled and closed, and it is difficult or even impossible to pull the zipper. The user needs to arrange the cabin skin connected to the zipper so that the two sides of the zipper are parallel before pulling the zipper, which is very inconvenient. In terms of details, when installing a zipper, if the zipper is straight, it will be very smooth to pull and close. However, if the zipper is arc-shaped or there is a bend in the middle of the straight line, the materials on both sides of the zipper are often not in a parallel state like a straight zipper when it is pulled and closed. The two pieces will bend in different directions and with different arcs. Therefore, the zipper head will encounter greater resistance when sliding, and may even fail to close normally.

[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0019] See also Figure 1 to Figure 2, showing an easy-to-pull non-linear zipper provided by an embodiment of the utility model, comprising a zipper strip 1 and a zipper cloth 2 connected to the zipper strip 1, the easy-to-pull non-linear zipper also comprising a support strip 3 and a positioning member 4, the number of the support strips 3 is at least two, the support strips 3 are distributed in parallel on both sides of the zipper strip 1, the extension direction of the support strip 3 is the same as the extension direction of the zipper strip 1, the support strip 3 is parallel to the zipper strip 1 and is spaced a predetermined distance apart, and the support strip 3 is mounted on the zipper cloth 2 through the positioning member 4.

[0020] In some specific embodiments, the support strip 3 is sleeved and fixed in the positioning member 4 so that the support strip 3 is bent and extended along the direction of the zipper strip 1, such as Figure 2 As shown, the positioning member 4 can be a plurality of positioning rings distributed at equal intervals, and the support strip 3 is sleeved and fixed in the positioning ring. In addition, the support strip 3 can be bent and fixed to the zipper cloth 2 by various methods such as grooving, bonding, and sewing. Adding the support strip 3 to the zipper cloth 2 can make the two sides of the zipper strip 1 always in a basically parallel state or a slightly misaligned state to make the pulling and closing smoother.

[0021] Specifically, the support strip 3 and the zipper strip 1 are located on the same horizontal plane.

[0022] Specifically, the distance between each of the support bars 3 and the zipper bar 1 is equal, and the distance is between 0.15 meters and 0.35 meters.

[0023] Specifically, the zipper strip 1 is a U-shaped zipper. In some specific embodiments, the easy-pull non-linear zipper can also be applied to other non-linear shapes besides the U-shape, such as C-shape, wave-shape, etc.
