DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Embodiment 1

[0021] See also Figure 1-4 , a fastener with vibration absorbing function, comprising a fastening frame 1, a vibration absorbing mechanism 2 is fixedly connected to the side of the fastening frame 1, and an interface vibration absorbing mechanism 3 is fixedly connected to the side of the fastening frame 1;

[0022] The vibration absorbing mechanism 2 includes an absorbing plate 21, the bottom end of the absorbing plate 21 is fixedly connected to a spring 22, the bottom end of the spring 22 is fixedly connected to a connecting plate 23, the bottom end of the connecting plate 23 is rotatably connected to a rotating rod 24, the side of the rotating rod 24 is rotatably connected to a slider 25, a sliding rod 26 is slidably connected inside the slider 25, a positioning block 27 is fixedly connected to the side of the fastening frame 1, a spring 28 is fixedly connected to the side of the positioning block 27, the bottom end of the connecting plate 23 is fixedly connected to a limiting rod 29, the side of the limiting rod 29 is slidably connected to a limiting frame 210, the two ends of the sliding rod 26 are fixedly connected to the sides of the two positioning blocks 27 respectively, and the outer bottom end of the limiting frame 210 is fixedly connected to the sides of the fastening frame 1. When the two sliding blocks 26 are subjected to the force of the rotating rod 24, they will move back to back and compress the spring 28 at the same time, so that the limiting The bottom end of the rod 29 is fixedly connected to the limit plate 211, and the bottom end of the limit plate 211 is fixedly connected to a spring three 212. One end of the spring two 28 is fixedly connected to the positioning block 27, and the other end is fixedly connected to the slider 25 at its side. One end of the spring three 212 is fixedly connected to the limit plate 211, and the other end is fixedly connected to the inner bottom end of the limit frame 210. When the absorption plate 21 is affected by the vibration force and moves toward the positioning block 27, the spring 22 will be compressed, and a part of the vibration force will be offset by the spring 22. The present application receives the vibration force attempting to act on the fastening frame 1 through the absorption plate 21, and subsequently acts on the spring 22, the spring two 28, and the spring three 212 first, and a part of it is offset by the elastic force of multiple groups of springs, and the other part of the vibration force is finally transmitted to the positioning block 27 and the limit frame 210 to be absorbed.

[0023] When the present embodiment is used, after the device is used to complete the tightening, when the external vibration attempts to act on the tightening frame 1, it will first contact the absorbing plate 21, and at this time, the spring 22 will be squeezed inward first. At this time, the elastic force of the spring 22 will offset a part of the vibration force, and then the remaining force will act on the connecting plate 23 through the spring 22, and continue to squeeze the connecting plate 23 downward. At this time, the rotating rod 24 connected to the bottom end of the connecting plate 23 is rotated. Under the action of the pressure given by the connecting plate 23, one end of the connecting plate 23 is rotatably connected to the connecting plate 23 and rotates while moving downward. At the same time, the other end rotates on the slider 25 and pushes the sliders 25 on both sides to move back on the slide bar 26, squeezing the spring 22. 8. At this time, the elastic force of the second spring 28 offsets part of the vibration force, and the remaining part of the vibration force will be absorbed by the positioning block 1 27 as the spring 28 finally acts on it. In addition, when the connecting plate 23 moves toward the direction of the sliding rod 1 26, the limiting rods 29 fixedly connected on both sides of its bottom end will also push the limiting plate 211 to move toward the inner bottom end of the limiting frame 210, while compressing the spring three 212. At this time, the elastic force of the third spring 212 also offsets part of the vibration force, and the remaining force will eventually be absorbed by the inner bottom end of the limiting frame 210 as the spring three 212 is compressed. The four sets of vibration absorbing mechanisms 2 can offset and absorb the vibration force that attempts to act on the fastening frame 1 in different directions.

[0024] Embodiment 2

[0025] See also Figure 5, a structural vibration absorbing mechanism 3 is added on the basis of the first embodiment, the interface vibration absorbing mechanism 3 includes an absorption plate 2 31, a spring 4 33 is fixedly connected to the bottom end of the absorption plate 2 31, a positioning block 2 37 is fixedly connected to the side of the fastening frame 1, one end of the spring 4 33 is fixedly connected to the absorption plate 2 31, and the other end is fixedly connected to the top of the positioning block 2 37. When the absorption plate 2 31 is subjected to the vibration force, the spring 4 33 will be compressed toward the direction of the positioning block 2 37. At this time, the elastic force of the spring 4 33 will offset a part of the vibration force. The bottom end of the absorption plate 2 31 is rotatably connected to the rotating rod 2 32, and the side of the rotating rod 2 32 is rotatably connected to the slider 2 34. The slider 2 34 is slidably connected to the sliding rod 2 35, and the side of the sliding rod 2 34 The surface is fixedly connected with a spring five 36, and the four-group interface vibration absorption mechanism 3 can effectively offset and absorb the vibration force trying to act on the two interfaces. The sliding rod two 35 passes through the spring five 36, and the spring five 36 is between the two sliding blocks two 34, and is fixedly connected to the two sliding blocks two 34 respectively. When the rotating rod two 32 causes the two sliding blocks two 34 to move toward each other, the two sliding blocks two 34 squeeze the spring five 36, and a part of the vibration force is offset by the elastic force of the spring five 36. The present application receives the vibration force trying to act on the two 1 interfaces through the absorption plate two 31, absorbs a part of it through the elastic force of the spring four 33, and the remaining part of the vibration force is transmitted to the positioning block two to be absorbed, and the other part of the vibration force is finally offset by the compression of the spring five 36.

[0026] When this embodiment is used, when part of the vibration force attempts to act on the interface of the two fastening frames 1, it will first contact the absorption plate 2 31, and the vibration force will act on the spring 4 33 at its bottom end through the absorption plate 2 31 to compress it. At this time, the elastic force on the spring 4 33 offsets part of the vibration force, and the remaining force finally acts on the positioning block 2 37 and is absorbed by it as the spring 4 33 is continuously compressed. When the absorption plate 2 31 transmits the vibration force to the spring 4 33, it also causes the rotating rod 2 32 whose bottom end is rotatably connected to it to rotate at its bottom end and move downward, while the other end of the rotating rod 2 32 rotates on the slider 2 34, and causes the sliders 2 34 on both sides to move toward each other on the slide rod 2 35, while compressing the spring 5 36. As the spring 5 36 is continuously compressed, this part of the vibration force is finally offset. The four-group interface vibration absorption mechanism 3 effectively offsets and absorbs the vibration forces attempting to act on the two interfaces.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
