Abstract
Description
Technical Field
[0001] The utility model relates to the field of core pull buckles, in particular to a two-way locking core pull buckle. Background Art
[0002] A zipper is an accessory used to adjust the length of a backpack strap (shoulder strap). With the continuous development of the luggage, apparel and other industries, the market demand for zipper, as an important accessory, is also increasing.
[0003] Existing zip-lock buckles are typically circular and consist of two parts: a pin and a buckle. The pin is attached to the buckle's surface, either one-third, two-thirds, or one-half of the way up. They are relatively simple to use. Typically, users simply thread the backpack strap through the pin and wrap it around it to secure it.
[0004] However, the pull-core buckle of the above structure has the following defects: since the fixing pin is fixed to the buckle, the fixing pin cannot be flexibly adjusted on the buckle, so the backpack strap can only be shortened by continuously winding it, and the position of the fixing pin cannot be flexibly adjusted. In addition, there is no other fixing part on the buckle, so the backpack strap cannot be fixed, which is inconvenient to fix the backpack strap and has poor practicality. Utility Model Content
[0005] In order to overcome the shortcomings of the existing technical solutions, the utility model provides a bidirectional locking pull core buckle, which can effectively solve the technical problems that the existing pull core buckles are inconvenient to adjust and inconvenient to fix backpack straps.
[0006] The technical solution adopted by the utility model to solve its technical problems is: a two-way locking pull core buckle, including a circular ring and a pull rod movably arranged on the circular ring, a plurality of positioning blocks are arranged on the surface of the circular ring, the circular ring and the positioning blocks are formed by integrated molding, and a slot is formed between adjacent positioning blocks, and a fixing part is formed at both ends of the circular ring, and the inner wall of the fixing part is in contact with the surface of the circular ring.
[0007] Furthermore, the fixing portion is in a barb shape.
[0008] Furthermore, the positioning blocks are divided into four groups, and the positioning blocks in the four groups are arranged and distributed at equal intervals.
[0009] Furthermore, the circular ring passes through the fixing portion, and the pull rod is slidably connected along the surface of the circular ring.
[0010] Furthermore, the ring and the pull rod are made of metal material.
[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: the bidirectional locking core buckle of the present invention facilitates the core buckle to fix the backpack strap by setting a positioning block and a slot, and by sliding the pull rod on the ring, the fixing part slides along the ring, so that the core buckle can be adjusted in two directions, greatly improving flexibility and facilitating adjustment of the length of the backpack strap. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0017] like Figure 1 and Figure 2 As shown, the bidirectional locking zipper comprises a ring 1 and a pull rod 2 movably arranged on the ring 1, a plurality of positioning blocks 4 are arranged on the surface of the ring 1, the ring 1 and the positioning blocks 4 are formed by integrated molding, and a card slot 5 is formed between adjacent positioning blocks 4, and a fixing part 3 is formed at both ends of the ring 1, and the inner wall of the fixing part 3 is in contact with the surface of the ring 1, and the fixing part 3 is in a hook shape, and the positioning blocks 4 are divided into four groups, and the four groups of positioning blocks 4 are evenly distributed. The ring 1 passes through the fixing part 3, and the pull rod 2 is slidably connected along the surface of the ring 1, and the ring 1 and the pull rod 2 are made of metal material. The card slot 5 formed between the positioning blocks 4 can accurately cooperate with the adjustment of the backpack strap to ensure that the locking and unlocking process of the backpack strap is smooth and reliable. The metal material has the advantages of high strength, high hardness, corrosion resistance, etc., which enhances the durability of the product.
[0018] The bidirectional locking drawstring buckle of this embodiment is convenient for fixing the backpack strap with the drawstring buckle by providing a positioning block 4 and a slot 5. By sliding the pull rod 2 on the ring 1, the fixing part 3 slides along the ring 1, so that the drawstring buckle can be adjusted in two directions, which greatly improves the flexibility and facilitates the adjustment of the length of the backpack strap. When in use, one end of the backpack strap is wound around the pull rod 2 so that one end of the backpack strap is wrapped and slides along the slot 5. By adjusting the position of the pull rod 2, the pull rod 2 is moved along the ring 1 to achieve the adjustment of the strap length. By adjusting the pull rod 2, the pull rod 2 and the ring 1 of the drawstring buckle can be tightly combined to prevent the backpack strap from accidentally slipping or shifting during use.
[0019] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description. It is intended that all variations within the meaning and range of equivalents of the claims be encompassed within the present invention, and any reference numerals in the claims should not be construed as limiting the claims to which they relate.
