[0025] The utility model is further described below in conjunction with the accompanying drawings;

[0026] like Figure 1-3As shown, a universal axial self-balancing anti-impact buffer connector is used to alleviate the impact caused by the device A generating the impact on the device B being buffered in the axial direction. The universal axial self-balancing anti-impact buffer connector comprises a lower connecting seat 1, a limiting shaft 2, a buffer member 3, an adjusting nut 4 and an upper connecting seat 5; wherein, a plurality of connecting bolts 8 are arranged on the circumference of the lower connecting seat 1 and the upper connecting seat 5, wherein the connecting bolts 8 on the lower connecting seat 1 are used to connect with the device A generating the impact, and the connecting bolts 8 on the upper connecting seat 5 are used to connect with the device B being buffered; a supporting protrusion 11 is formed on the lower connecting seat 1, and a groove matching the outer shape of the limiting shaft 2 is arranged on the supporting protrusion 11, and the limiting shaft 2 is placed in the aforementioned groove and connected to the supporting protrusion 11 by a positioning bolt 6; it should be noted that a concealed groove is provided at a position corresponding to the supporting protrusion 11 on the lower connecting seat 1, and the screw head of the positioning bolt 6 is placed in the concealed groove;

[0027] The upper connecting seat 5 has a connecting portion 51, which is formed by the bottom of the upper connecting seat 5 being recessed upward and two side portions being recessed inward. The connecting portion 51 is slidably connected to both ends of the limiting shaft 2; adjusting nuts 4 are provided at both ends of the limiting shaft 2, and a buffer 3 is provided between the adjusting nut 4 and the connecting portion 51, and the connecting seat 5 is positioned on the limiting shaft 2 by clamping the adjusting nut 4 and the buffer 3; in order to make the force on the buffer 3 more balanced, a fixing cover 7 is provided between the buffer 3 and the connecting portion 51 and between the buffer 3 and the adjusting nut 4, and the fixing cover 7 and the buffer 3 are both arranged on the limiting shaft 2 in a sleeve manner; the buffer 3 is mainly made of thermoplastic polyurethane, and can also be replaced by other materials with the same buffering effect, such as high-elastic rubber, nylon, etc.

[0028] In order to ensure the stability of the universal axial self-balancing anti-impact buffer connector, in this embodiment, the number of the limit shaft 2 and the supporting protrusion 11 are both two, wherein the two supporting protrusions 11 are arranged side by side along the radial direction of the balancer, and each limit shaft 2 is connected to the supporting protrusion 11 by two positioning bolts 6;

[0029] In order to ensure the lightness of the universal axial self-balancing anti-impact buffer connector, in the present embodiment, hollow weight-reducing holes are provided on the lower connecting seat 1 and the upper connecting seat 5 .

[0030] The device A generating the impact and the device B being buffered are fixed together by the utility model and are relatively still. When the device A generating the impact suddenly moves at high speed (or suddenly changes from moving to stillness), the device B being buffered will be subjected to a huge impact force generated by the speed change of the device A generating the impact due to the action of inertia. At this time, the buffer 3 is elastically compressed to play an impact-resistant and shock-absorbing role. After the impact is over, since there are buffers 3 on both sides with the same elasticity, the buffered device B will self-balance and restore to the position before the impact. The buffers 3 on both sides of the limit shaft 2 are locked by the adjusting nuts 4. By adjusting the pre-tightening force of the adjusting nuts 4, the damping of the entire device can be adjusted to adapt to impacts under different states, and the material of the buffer 3 can be replaced. For example, when it is replaced with rubber material, the material has a smaller elastic coefficient and is softer in comparison, which can increase the buffering effect of the product. When it is replaced with nylon material, the elastic coefficient is larger, harder, and has greater compressive strength, and can be used in scenarios with large impact forces.

[0031] The above description is only a preferred specific implementation mode of the present invention and is not a limitation of the present invention. Any equivalent substitutions and modifications made by any technical personnel in this field without departing from the guidance of the present invention should be deemed to fall within the protection scope of the present invention.
