Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0042] See also Figures 1 to 10 , which is a zipper 100 provided in one embodiment of the present invention, includes two first chain belts 110 , two second chain belts 120 , two secondary lock buckles 130 and two main lock buckles 140 .

[0043] See also Figure 1 and Figure 2 , wherein the two first chain belts 110 are arranged opposite to each other, a second chain belt 120 can be engaged with or separated from a first chain belt 110, a secondary lock buckle 130 is slidably arranged on a second chain belt 120, and the two main lock buckles 140 can be locked or separated with each other. The two main lock buckles 140 in the locked state can slide along the first chain belt 110 to make the two first chain belts 110 engage or separate, and the two main lock buckles 140 in the separated state can each be locked with or separated from a secondary lock buckle 130. The main lock buckle 140 and the secondary lock buckle 130 in the locked state can drive a first chain belt 110 and a second chain belt 120 to engage or separate.

[0044] The above-mentioned zipper 100 includes two first chain straps 110 and two second chain straps 120. The two first chain straps 110 are engaged or separated by pulling the two main lock buckles 140 in a locked state. The main lock buckle 140 is pulled to slide close to the secondary lock buckle 130 and locked or separated with the secondary lock buckle 130, thereby achieving the engagement or separation of the entire zipper 100. By setting multiple chain straps and multiple lock buckles, the entire zipper 100 can be opened in multiple directions, so that the entire zipper 100 has a larger opening area to adapt to different application scenarios, which facilitates the use of the zipper 100 in different scenarios.

[0045] See also Figure 2In one embodiment of the present use novel, the first chain belt 110 is provided with a first chain tooth 111 and a second chain tooth 112 separately, wherein the number of the second chain teeth 112 is greater than the number of the first chain teeth 111. In other embodiments, the number of the first chain teeth 111 can be set to be greater than the number of the second chain teeth 112 as required. In addition, since the main lock buckle 140 needs to slide back and forth on the first chain tooth 111 and the second chain tooth 112, in order to facilitate the main lock buckle 140 to move in the interval between the first chain tooth 111 and the second chain tooth 112, a slide rail 113 is connected between the first chain tooth 111 and the second chain tooth 112, so that when the main lock buckle 140 slides back and forth between the first chain tooth 111 and the second chain tooth 112, the friction resistance with the chain belt cloth is reduced, so that the zipper 100 can be quickly engaged or separated, thereby facilitating the use of the user.

[0046] Please continue reading Figure 2 In one embodiment of the present invention, the two second chain belts 120 are connected as one, so as to facilitate the production of the second chain belt 120. At the same time, when sewing the second chain belt 120 to the fabric, it is also convenient to sew the second chain belt 120, and it also prevents the secondary lock buckle 130 from slipping out from the edge of the second chain belt 120 during use, thereby facilitating the use of the user.

[0047] Among them, the second chain belt 120 is provided with third chain teeth 121, wherein the number of the third chain teeth 121 is the same as the number of the second chain teeth 112, and the second chain teeth 112 on the first chain belt 110 are used to bite with the third chain teeth 121 on the second chain belt 120, thereby realizing the closure of the entire zipper 100.

[0048] Also, see Figure 1 and Figure 2 A sealing portion 122 is provided at the connection between the two second chain belts 120. When the zipper 100 is closed, the sealing portion 122 contacts the two first chain belts 110. Therefore, when the zipper 100 is in a closed state, the entire zipper 100 is in a sealed state without hollowing out, thereby facilitating the use of the zipper 100 on fabrics and improving its practicality.

[0049] Specifically, when the zipper 100 is in a closed state, the sealing portion 122 is in close contact with the two slide rails 113 on the two first chain belts 110, thereby preventing the zipper 100 from being hollowed out and placing the entire zipper 100 in a sealed state, thereby enabling the opening of the fabric to be sealed by the zipper.

[0050] See also Figures 3 to 5In one embodiment of the present invention, the main lock buckle 140 includes a handle 141, a pull head 142 and a locking mechanism 143. The handle 141 is connected to the pull head 142, and specifically, the handle 141 is rotatably connected relative to the pull head 142. The locking mechanism 143 includes a pressing member 1431 and a limiting member 1432, and the pressing member 1431 is slidably connected relative to the pull head 142, so that the pressing member 1431 can slide relative to the pull head 142 when pressed by an external force, and push the limiting member 1432 to be locked with another main lock buckle 140 or the auxiliary lock buckle 130.

[0051] Specifically, the slider 142 is provided with a first limiting groove 1421, and the secondary lock buckle 130 is provided with a second limiting groove 131. The limiting member 1432 on one main lock buckle 140 can slide into the first limiting groove 1421 on another main lock buckle 140 or the second limiting groove 131 on a corresponding secondary lock buckle 130 when the pressing member 1431 is pressed by external force, so as to lock the two main lock buckles 140 or lock a main lock buckle 140 and a corresponding secondary lock buckle 130.

[0052] In a specific embodiment, for example, a bayonet can be provided on the limit member 1432, and a corresponding blocking block is provided in the first limit groove 1421 or the second limit groove 131. When the pressing member 1431 is pressed by an external force, the limit member 1432 is pushed to slide into the first limit groove 1421 or the second limit groove 131. At this time, the blocking block provided in the first limit groove 1421 or the second limit groove 131 is correspondingly blocked in the bayonet provided on the limit member 1432, so that the two main lock buckles 140 or one main lock buckle 140 and one auxiliary lock buckle 130 are locked with each other. When the two main lock buckles 140 or one main lock buckle 140 and one auxiliary lock buckle 130 need to be separated, the pressing piece 1431 is pushed again, so that the pressing piece 1431 pushes the latch of the limiting piece 1432 to disengage from the blocking block set in the first limiting groove 1421 or the second limiting groove 131, and then the pressing piece 1431 is pulled to pull the limiting piece 1432 out of the first limiting groove 1421 or the second limiting groove 131, thereby realizing the separation of the two main lock buckles 140 or one main lock buckle 140 and one auxiliary lock buckle 130.

[0053] When the zipper 100 needs to be opened, the main lock buckle 140 is pulled toward the auxiliary lock buckle 130 so that the main lock buckle 140 and the auxiliary lock buckle 130 are locked together. The zipper 100 can be opened by continuing to pull the main lock buckle 140. The zipper 100 can be closed and opened at one time by pulling the main lock buckle 140, which is convenient for users.

[0054] Specifically, see Figure 6 and Figure 7In one embodiment of the present invention, the locking mechanism 143 further includes a guide member 1433, a heart-shaped slide groove 14311 is provided on the pressing member 1431, one end of the guide member 1433 is rotatably connected to the slider 142, and the other end of the guide member 1433 is slidably connected to the heart-shaped slide groove 14311. When the two main lock buckles 140 are locked or one main lock buckle 140 and one secondary lock buckle 130 are locked, the other end of the guide member 1433 is located at the vertex 14311a of the heart-shaped slide groove 14311. When the two main lock buckles 140 are in a separated state or one main lock buckle 140 and one secondary lock buckle 130 are in a separated state, one end of the guide member 1433 is located in the concave portion 14311b of the heart-shaped slide groove 14311.

[0055] In one embodiment of the present invention, the locking mechanism 143 further includes an elastic member 1434, and the elastic member 1434 is connected between the pressing member 1431 and the pull head 142. Therefore, when the limiting member 1432 is locked in the first limiting groove 1421 or the second limiting groove 131, it is subjected to the pulling force of the elastic member 1434. When the two main lock buckles 140 or the main lock buckle 140 and the auxiliary lock buckle 130 need to be unlocked, the limiting member 1432 is subjected to the pulling force of the elastic member 1434 when it slides out of the first limiting groove 1421 or the second limiting groove 131, so that the limiting member 1432 can return to its original position quickly.

[0056] In one embodiment of the present invention, the locking mechanism 143 further includes a connecting member 1435, and the two ends of the connecting member 1435 are respectively connected to the pressing member 1431 and the limiting member 1432 for rotation. In the present embodiment, the connecting member 1435 is block-shaped, and in other embodiments, the connecting member 1435 can be columnar or sheet-shaped. The limiting member 1432 is block-shaped and arc-shaped, and correspondingly, the first limiting groove 1421 and the second limiting groove 131 are also arc-shaped, and the curvatures of the limiting member 1432, the first limiting groove 1421 and the second limiting groove 131 are equal. When the pressing member 1431 is pressed, since the connecting member 1435 is rotated relative to the pressing member 1431, the connecting member 1435 pushes the limiting member 1432 connected to it for rotation to rotate, thereby causing the limiting member 1432 to slide in the first limiting groove 1421 and the second limiting groove 131.

[0057] In addition, in a specific embodiment of the present invention, the slider 142 includes a locking cover 1422 and a locking seat 1423, and the locking mechanism 143 is connected to the locking cover 1422 and can slide relative to the locking cover 1422. In other embodiments, the locking mechanism 143 can be connected to the locking seat 1423 and slide relative to the locking cover 1422.

[0058] Specifically, one end of the guide member 1433 is rotatably connected relative to the locking cover 1422, and the other end is slidably connected relative to the pressing member 1431. The elastic member 1434 is connected between the pressing member 1431 and the locking cover 1422. One end of the connecting member 1435 is rotatably connected relative to the pressing member 1431, and the other end is rotatably connected relative to the limiting member 1432.

[0059] When the locks need to be locked or separated, the pressing member 1431 is pressed by external force, and one end of the guide member 1433 is rotatably connected to the lock cover 1422, so that the other end of the guide member 1433 can slide relative to the pressing member 1431 along the slide groove provided in the pressing member 1431, thereby limiting the moving position of the pressing member 1431 by sliding the other end of the guide member 1433 relative to the pressing member 1431 between different positions in the pressing member 1431. Since the elastic member 1434 is connected between the pressing member 1431 and the lock cover 1422, when the lock is in a separated state, the elastic member 1434 is in a compressed state, and when the pressing member 1431 is pressed by external force, the elastic member 1434 generates an elastic force to restore the original state. The pressing member 1431 drives the connecting member 1435 to rotate relative to the pressing member 1431, and the connecting member 1435 drives the limiting member 1432 to rotate relative to the connecting member 1435, thereby driving the limiting member 1432 to slide into the first limiting groove 1421 or the second limiting groove 131, thereby realizing the locking between the main lock buckles 140 or the locking between the main lock buckle 140 and the auxiliary lock buckle 130; when the main lock buckles 140 need to be separated or the main lock buckle 140 and the auxiliary lock buckle 130 need to be locked, the locking mechanism 1430 can be realized. When the pressing member 1431 needs to be separated, an external force presses the pressing member 1431, and the elastic member 1434 in the compressed state continues to be compressed. At the same time, the other end of the guide member 1433 quickly slides to another position relative to the pressing member 1431, and the guide member 1433 drives the connecting member 1435 to rotate, and the connecting member 1435 drives the limiting member 1432 to move in the opposite direction, so that the connecting member 1435 slides out of the first limiting groove 1421 or the second limiting groove 131, so that the locking members are unlocked from each other.

[0060] In one embodiment of the present invention, the two pressing members 1431 are slidably connected to the two opposite sides of the two pull heads 142, so that when pressed by hand, the operation of the hand is facilitated and the operation can be completed with one hand.

[0061] Specifically, the pressing member 1431 is square, and a sliding opening 14221 is correspondingly provided on the lock cover 1422. The pressing member 1431 can slide in the sliding opening 14221 along the pressing direction under external pressure. It can be understood that the sliding opening 14221 is square. In other embodiments, the pressing member 1431 and the sliding opening 14221 of other shapes may be provided, such as trapezoidal, cylindrical, etc.

[0062] The two opposite ends of the guide member 1433 are bent in opposite directions, one end of which forms a connecting portion 14332 and the other end forms a sliding portion 14331. The sliding portion 14331 is used for sliding connection with the relative pressing member 1431, and the connecting portion 14332 is used for rotational connection with the locking cover 1422.

[0063] In one embodiment of the present invention, the elastic member 1434 is connected between the pressing member 1431 and the lock cover 1422. When the locks are in an interlocked state, the elastic member 1434 is in a first compressed state. When an external force presses the pressing member 1431, the elastic member 1434 is compressed to a second compressed state. When two main lock buckles 140 or one main lock buckle 140 and one auxiliary lock buckle 130 need to be locked, the elastic member 1434 can give the pressing member 1431 a push back to facilitate the use of the lock. Specifically, the elastic member 1434 in this embodiment is a spring. In other embodiments, the elastic member 1434 can be a spring formed by multiple sections of bending or other elastic components.

[0064] In addition, in order to increase the tightness of the combination between the lock cover 1422 and the lock seat 1423, a receiving groove 14231 is provided in the lock seat 1423. In this embodiment, the connecting member 1435 is received in the receiving groove 14231. Therefore, when the lock cover 1422 covers the locking mechanism 143 and covers the lock seat 1423, the two can have more contact area, making the connection between the two more stable, for example, when the two are bonded, the connection between the two can be more stable.

[0065] The usage process between the above-mentioned main lock buckles 140 or between the main lock buckle 140 and the auxiliary lock buckle 130 is as follows: when the two main lock buckles 140 need to be separated, the pressing piece 1431 is pressed to make the guide piece 1433 slide along the vertex 14311a of the heart-shaped slide groove 14311 in the pressing piece 1431 to the recess 14311b of the heart-shaped slide groove 14311, and at the same time, the pressing piece 1431 pushes the connecting piece 1435 to move, and the connecting piece 1435 pushes the limiting piece 1432 to slide out in the direction away from the first limiting groove 1421 or the second limiting groove 131. At the same time, because the guide piece 1433 is located in the recess 14311b of the heart-shaped slide groove 14311 in the pressing piece 1431, the pressing piece 1431 is locked. At this time, the two main lock buckles 140 or the main lock buckle 140 and the auxiliary lock buckle 130 are separated. For details, please refer to Fig. 9When the two main lock buckles 140 need to be locked, the pressing member 1431 is pressed, and the elastic member 1434 is compressed, so that the guide member 1433 slides along the concave portion 14311b of the heart-shaped slide groove 14311 in the pressing member 1431 to the vertex 14311a of the heart-shaped slide groove 14311. At this time, the pressing member 1431 slides toward the outside of the slider 142, and at the same time pulls the connecting member 1435 to move toward the outside of the slider 142. The connecting member 1435 pulls the limiting member 1432 to slide into the first limiting groove 1421 or the second limiting groove 131. At this time, the two main lock buckles 140 or the main lock buckle 140 and the auxiliary lock buckle 130 are locked. For details, please refer to Figure 8 and Fig.10 .

[0066] The usage process of the above-mentioned zipper 100 is as follows: when the zipper 100 needs to be opened, the two locked main lock buckles 140 move toward the auxiliary lock buckle 130, and then the two main lock buckles 140 are separated. Each main lock buckle 140 is locked with a corresponding auxiliary lock buckle 130, and one main lock buckle 140 drives one auxiliary lock buckle 130 to move along the second chain tooth 112 and the third chain tooth 121, thereby realizing the opening of the second chain belt, and then realizing the opening of the zipper 100; when the zipper 100 needs to be closed, the main lock buckle 140 and the auxiliary lock buckle 130 are pulled in opposite directions to achieve closure.

[0067] The above-mentioned zipper 100 is designed with two first chain belts 110 and two second chain belts 120, and one second chain belt 120 can be engaged or separated with one first chain belt 110. Two main lock buckles 140 are designed to engage or separate the two first chain belts 110. The main lock buckles 140 are then moved to cooperate with the auxiliary lock buckles 130 to engage or separate the second chain belt 120 from the first chain belt 110, so that the zipper 100 is equivalent to having two sub-zippers separating when separating, that is, separation in multiple directions is achieved, the zipper opening area is increased, and it is convenient to use.

[0068] In other embodiments, the present invention further provides a fabric, comprising a fabric body and a zipper, wherein the zipper is the zipper described above.
