[0025] Specific embodiment 1: Please refer to Figure 1-4 A buckle that opens up and down comprises an upper buckle plate and a lower buckle plate.
[0026] The upper buckle plate includes a buckle end 2 and a rope connection end 1. The rope connection end 1 is fixedly connected with the buckle end 2 in an upper and lower structure. The rope connection end 1 is composed of two longitudinal rods and three transverse rods fixedly connected. The setting of the rope connection end can help the buckle plate to complete the connection of the rope.
[0027] The buckle end 2 is provided with a limiting column 3. The limiting column 3 is provided at the center of the buckle end 2 and is located on the upper surface of the buckle end 2. The outer end surface diameter of the limiting column 3 is larger than the column diameter of the limiting column 3.
[0028] The upper buckle plate and the lower buckle plate are detachably connected via a limiting column 3 .
[0029] The lower plug-in buckle plate includes a buckle end 2 4 and a rope connecting end 2 5. The rope connecting end 2 5 is fixedly connected with the buckle end 2 4 in an upper and lower structure.
[0030] The second rope end 5 is composed of two longitudinal rods and two transverse rods fixedly connected.
[0031] The buckle end 2 4 comprises a cover 6, a locking tongue device 1, a locking tongue device 2 and a receiving cavity.
[0032] The accommodating cavity opens upward and is through-connected from left to right.
[0033] The first and second locking tongue devices are symmetrically arranged around the center of the bottom surface of the accommodating cavity and are located on the upper surface of the bottom surface of the accommodating cavity. The locking tongue devices have a side surface that abuts against the side wall of the accommodating cavity, and a claw is arranged at the front end of the locking tongue device. The claws are respectively arranged around the upper and lower sides of the limiting column 3 to clamp the limiting column 3. The locking tongue devices are all provided with waist-shaped holes.
[0034] The first locking tongue device and the second locking tongue device have the same structure.
[0035] The upper surface of the bottom surface of the accommodating cavity is fixedly provided with a first limit block 20. The first limit block 20 corresponds to the waist-shaped hole position one by one. By setting the first limit block 20, the range of lateral and longitudinal movement of the locking tongue device is limited.
[0036] The front end of each locking tongue device is provided with a second spring 21; the two ends of the second spring 21 are respectively abutted against the front end of the locking tongue device and the lower end of another locking tongue device. The provision of the second spring 21 can help the locking tongue device to complete the reset.
[0037] The inner side of the front end of the locking tongue device is provided with an inclined surface, and the position of the inclined surface corresponds to the position of the limiting column 3. The inclined surface can help the limiting column to smoothly push the locking tongue device open.
[0038] A groove is provided at the center of the upper surface of the bottom of the accommodating cavity; the position of the groove corresponds to the position of the limiting column 3, and the sizes thereof match.
[0039] The front and rear ends of the side walls of the accommodating cavity are both provided with second limit blocks 18; the second limit blocks 18 are respectively abutted against the upper and lower sides of the outer end surface of the locking tongue device to prevent the locking tongue device from moving laterally outside the accommodating cavity. A groove is provided on the upper surface of the bottom of the accommodating cavity, and the size of the groove is the same as the size of the front end surface of the limit column 3.
[0040] The cover 6 is detachably arranged above the accommodating cavity by rivets, and covers the upper surfaces of the first and second locking tongue devices; a notch 9 is arranged on the cover 6; the notch 9 corresponds to the position of the limiting column 3 and has the same size as the limiting column 3. The arrangement of the cover 6 can also prevent the locking tongue device installed on the upper surface of the bottom of the accommodating cavity from falling out of the accommodating cavity when it is placed horizontally.
[0041] Working principle: The upper and lower plug buckle plates are placed in an up-and-down structure, and the buckle end 2 4 is clamped above the buckle end 1 2. The limit column 3 pushes the switch 7 along the inclined surface on the lock tongue device, enters the groove on the upper surface of the bottom of the accommodating cavity of the lower plug buckle plate, and completes the locking of the plug buckle. When the left and right sides of the lock tongue device move toward the limit column 3 at the same time, the front end of the lock tongue device releases the limit column 3 around the claw at the same time. The design of the limit column is used to release and lock the plug buckle, so as to achieve the purpose of operating the plug buckle with one hand, and the first limit block is set to avoid the situation where the lock tongue device is pressed too hard to damage the second spring 21.
[0042] Specific embodiment 2: Figure 5 As shown, the difference from the specific embodiment 1 is that a connecting ring 10 is rotatably provided on the rope connecting end 1 of the upper buckle plate. The two ends of the connecting ring 10 are respectively fixedly connected to the left and right sides of the rope connecting end 1. The arrangement of the connecting ring 10 reduces the contact with the buckle when the buckle position is moved, and it is not easy to accidentally touch the switch 7.
[0043] Specific embodiment 3: The difference from specific embodiment 1 is that the bolt device includes a switch 7 and a push rod 8; the switch 7 is respectively arranged on the left and right sides of the upper surface of the bottom of the accommodating cavity; one end of the switch 7 is rotatably connected to the bottom of the accommodating cavity by a screw; the other end of the switch 7 abuts against the outer end of the push rod 8. The cover 6 is detachably arranged above the accommodating cavity by screws.
[0044] A first spring 16 is disposed at the front end of the locking tongue device; a stopper 17 is disposed on the upper surface of the bottom of the accommodating cavity; the front and rear ends of the first spring 16 abut against the front end of the locking tongue device and the stopper 17 respectively.
[0045] Specific embodiment 4: The difference from specific embodiment 3 is that a connecting ring 10 is rotatably provided on the upper plug-in plate rope connection end 1. The two end ports of the connecting ring 10 are rotatably connected to the left and right sides of the rope connection end 1 respectively.
