[0026] Meanwhile, the left and right locking slots are semi-circular slots arranged opposite each other. The left locking part is a minor arc arch arranged concentrically with the left locking slot, and the right locking part is a minor arc arch arranged concentrically with the right locking slot. When the left locking part rotates back into the left locking slot, part of the right locking part will still be placed in the left locking slot, or vice versa, so that the left and right buckles remain locked. That is, the left and right buttons need to be pressed simultaneously to make the left and right locking parts retract into the left and right locking slots respectively, so that the buckles can be unlocked. This avoids accidental unlocking of the buckles and makes the buckle structure more secure and stable. Attached Figure Description

[0034] See attached document Figures 1 to 6 The present invention provides a further detailed description of a push-button type snap fastener.

[0035] A push-button buckle includes a left buckle 1 and a right buckle 2. Both the left buckle 1 and the right buckle 2 are provided with connecting holes 5 for connecting webbing. The connecting holes 5 can also be connected to connecting straps such as round ropes, belts, and rubber-coated tapes. The left buckle 1 is provided with a left prong 11 and a left slot 12, and the right buckle 2 is provided with a right prong 21 and a right slot 22.

[0036] The left buckle 1 is provided with a left locking groove 13, and the right buckle 2 is provided with a right locking groove 23. The left locking groove 13 and the right locking groove 23 are semi-circular grooves arranged opposite each other, wherein the left locking groove 13 and the right locking groove 23 cooperate to form a circular groove.

[0037] The left buckle 1 is provided with a left locking member 14 and a left elastic member 15. The left locking part 141 of the left locking member 14 is rotatably disposed in the left locking groove 13. The left locking part 141 is a minor arc bow arranged concentrically with the left locking groove 13.

[0038] The right buckle 2 is provided with a right locking member 24 and a right elastic member 25. The right locking part 241 of the right locking member 24 is rotatably disposed in the right locking groove 23. The right locking part 241 is a minor arc bow arranged concentrically with the right locking groove 23. The left elastic member 15 and the right elastic member 25 can be one of a spring, a torsion spring, or a tension spring.

[0039] When the left buckle 1 and the right buckle 2 are inserted, the left pin 11 and the right pin 21 are inserted into the right slot 22 and the left slot 12 respectively, so that the left locking groove 13 and the right locking groove 23 are positioned opposite each other; wherein the left locking member 14 in the left locking groove 13 is driven by the left elastic member 15, and a part of the left locking part 141 is rotated into the right locking groove 23; at the same time, the right locking member 24 in the right locking groove 23 is driven by the right elastic member 25, and a part of the right locking part 241 is rotated into the left locking groove 13; so that the left buckle 1 and the right buckle 2 are locked together; avoiding the problem that existing buckles can not be firmly connected together because the elasticity of the elastic hook deteriorates when it engages with the snap on the female buckle;

[0040] Meanwhile, the left locking groove 13 and the right locking groove 23 are semi-circular grooves arranged opposite each other. The left locking part 141 is a minor arc arranged concentrically with the left locking groove 13, and the right locking part 241 is a minor arc arranged concentrically with the right locking groove 23. That is, the left locking part 141 is smaller than the left locking groove 13, and the right locking part 241 is smaller than the right locking groove 23. When the left locking part 141 rotates back into the left locking groove 13, part of the right locking part 241 will still be placed in the left locking groove 13, or when the right locking part 241 rotates back into the right locking groove 23, part of the left locking part 141 will still be placed in the right locking groove 23, so that the left buckle 1 and the right buckle 2 are still locked. That is, the left button 3 and the right button 4 need to be pressed at the same time to make the left locking part 141 and the right locking part 241 retract into the left locking groove 13 and the right locking groove 23 respectively, so that the buckle can be unlocked. This avoids the situation of accidentally unlocking the buckle and makes the buckle structure more solid and stable.

[0041] The left pin 11 is provided with a left pushing part 113, and the right pin 21 is provided with a right pushing part 213; one end of the left locking part 141 is connected to a left abutting arm 142, and the left elastic member 15 abuts against the left abutting arm 142, driving a portion of the left locking part 141 to extend out of the left locking groove 13; one end of the right locking part 241 is connected to a right abutting arm 243, and the right elastic member 25 abuts against the right abutting arm 243, driving a portion of the right locking part 241 to extend out of the right locking groove 23;

[0042] When the left buckle 1 and the right buckle 2 are inserted into each other, the left pushing part 113 pushes the right locking part 241 into the right locking groove 23 and compresses the right elastic member 25; at the same time, the right pushing part 213 pushes the left locking part 141 into the left locking groove 13 and compresses the left elastic member 15; as the left buckle 1 and the right buckle 2 approach each other, the left pushing part 113 and the right locking part 241 are offset, and the right pushing part 213 and the left locking part 141 are offset. Under the action of the left elastic member 15 and the right elastic member 25 respectively, a part of the left locking part 141 extends into the right locking groove 23, and a part of the right locking part 241 extends into the left locking groove 13, so that the left buckle 1 and the right buckle 2 are firmly locked together.

[0043] The left locking groove 13 is provided with a left guide post 131 at its center, and the left locking part 141 is provided with a left guide groove 1411 that matches the left guide post 131; the right locking groove 23 is provided with a right guide post 231 at its center, and the right locking part 241 is provided with a right guide groove 2411 that matches the right guide post 231.

[0044] The left locking part 141 and the right locking part 241 are guided back and forth by the left guide post 131 and the right guide post 231 respectively, making the product structure of the buckle more stable.

[0045] The left locking part 141 is connected to a left swing arm 143 at the other end, and a left button 3 that cooperates with the left swing arm 143 is slidably disposed on the left pin 11; the right locking part 241 is connected to a right swing arm 242 at the other end, and a right button 4 that cooperates with the right swing arm 242 is slidably disposed on the right pin 21.

[0046] To unlock the buckle, press the left button 3 and the right button 4 simultaneously. The left button 3 drives the left swing arm 143 to rotate the left locking part 141 in the opposite direction and causes the left abutment arm 142 to compress the left elastic element 15. The right button 4 drives the right swing arm 242 to rotate the right locking part 241 in the opposite direction and causes the right abutment arm 243 to compress the right elastic element 25. This causes the left locking part 141 and the right locking part 241 to retract into the left locking groove 13 and the right locking groove 23 respectively, thus unlocking the buckle. The operation is simple and convenient.

[0047] The left pin 11 is inclined towards the right pin 21 with a left guide surface 111, and the right pin 21 is inclined towards the left pin 11 with a right guide surface 211. When the left button 3 and the right button 4 are pressed simultaneously, the left guide surface 111 and the right guide surface 211 press against each other, causing the left pin 11 and the right pin 21 to slide in opposite directions, so that the left buckle 1 and the right buckle 2 automatically separate. Only one hand needs to press the left button 3 and the right button 4 at the same time to release the left locking part 141 and the right locking part 241 from locking the right pin 21 and the left pin 11 respectively, and the left buckle 1 and the right buckle 2 will automatically separate. This realizes the one-handed buckle unlocking operation, making the buckle unlocking operation more convenient.

[0048] The left pin 11 is provided with a left sliding groove 112, and the lower end of the left button 3 is provided with a left sliding post 31, which is adapted to the left sliding groove 112; the right pin 21 is provided with a right sliding groove 212, and the lower end of the right button 4 is provided with a right sliding post 41, which is adapted to the right sliding groove 212; when the left button 3 and the right button 4 are pressed simultaneously, the left sliding post 31 will cooperate with the left sliding groove 112 to guide the left button 3 to slide forward, and the right sliding post 41 will cooperate with the right sliding groove 212 to guide the right button 4 to slide forward; when the left button 3 and the right button 4 are released, the left elastic element 15 will push the left swing arm 143 to rotate in the opposite direction, causing the left button 3 to slide backward, thus resetting; the right elastic element 25 will push the right swing arm 242 to rotate in the opposite direction, causing the right button 4 to slide backward, thus resetting.
