[0031] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0032] A shock-absorbing fixing fitting of the present utility model, as Figure 1 shown, includes a main body frame 1, a fastening component 2 and a shock-absorbing component 3.

[0033] The main body frame 1 includes an upper cover plate 11, a lower cover plate 12 and a connecting platform; wherein both the upper cover plate 11 and the lower cover plate 12 are tubular cover plates with a semi-circular cross-section. On both sides of the tube wall of the upper cover plate 11, first connecting plates extending outward in the diameter direction are respectively provided, and two first bolt holes are arranged on the first connecting plates; on both sides of the tube wall of the lower cover plate 12, second connecting plates corresponding to the first connecting plates are provided, and two second bolt holes corresponding to the first bolt holes are also arranged on the second connecting plates. The upper cover plate 11 and the lower cover plate 12 are connected by a connecting member, and the connecting member is a connecting bolt 13 and a nut; the two first connecting plates and the second connecting plates are buckled together, and the connecting bolt 13 passes through the first bolt hole and the second bolt hole, and is fixed by the nut, so as to realize the fixed connection of the upper cover plate 11 and the lower cover plate 12. A reinforcing rib 14 is also arranged between the two connecting bolts 13 to further ensure the connection effect. As Figure 3 shown, after the upper cover plate 11 and the lower cover plate 12 are connected, a circular hollow cavity is formed for fixing an external wire or bus bar. The upper cover plate 11, the lower cover plate 12 and the connecting platform are all made of a high-strength alloy non-magnetic material, and have good anti-eddy current ability, load-bearing capacity and corrosion resistance.

[0034] The upper end of the connecting platform is adapted to the lower cover plate 12 and is fixedly connected to the bottom of the lower cover plate 12. The lower end of the connecting platform is divided into a first connecting platform and a second connecting platform from top to bottom, and the diameter of the first connecting platform is larger than that of the second connecting platform. A threaded hole is arranged at the center of the second connecting platform, and the depth of the threaded hole is greater than the thickness of the second connecting platform, that is, the threaded hole extends into the first connecting platform. The bottom of the threaded hole is designed to be conical, which reduces the resistance during the installation and disassembly process and prevents jamming.

[0035] As Figure 1 , Figure 2As shown in the figure, the fastening component 2 includes a mounting platform for fixedly connecting with an external device; a mounting groove 24 is provided at the bottom of the mounting platform, and a through hole penetrating the mounting platform is provided above the mounting groove 24. In this embodiment, the mounting platform includes a fixed base 21, a first fixed platform 22, and a second fixed platform 23 that are sequentially connected from bottom to top and have diameters decreasing in sequence. The mounting groove 24 is opened at the bottom end of the fixed base 21, and the through hole penetrates the first fixed platform 22 and the second fixed platform 23 from bottom to top. A plurality of fixing bolt holes are provided on the outer periphery of the fixed base 21 for passing through fixing bolts, and the fixing bolts tightly connect the fixed base 21 with the external device. The diameter of the second fixed platform 23 is the same as the diameter of the second connecting platform. The mounting groove 24 and the through hole are both coaxial with the threaded hole.

[0036] The shock-absorbing component 3 is connected between the main body frame 1 and the fastening component 2. The shock-absorbing component 3 includes a connecting rod 33 and a buffer spring. A positioning platform is provided at the lower end of the connecting rod 33. The diameter of the positioning platform is smaller than the diameter of the mounting groove 24 and larger than the diameter of the through hole. The thickness of the positioning platform is smaller than the depth of the mounting groove 24, and the positioning platform is placed in the mounting groove 24. The connecting rod 33 passes through the through hole, and its upper end is connected to the connecting platform; in this embodiment, a thread is provided at the upper end of the connecting rod 33 and is threadedly connected to the connecting platform through the threaded hole.

[0037] The buffer spring includes a first spring 31 and a second spring 32. The diameter of the first spring 31 is larger than the diameter of the second spring 32, and the diameter of the second spring 32 is adapted to the diameter of the connecting rod 33. The second spring 32 is sleeved on the connecting rod 33, and its upper and lower ends respectively abut against the second connecting platform and the second fixed platform 23. The first spring 31 is sleeved on the outside of the second connecting platform, the second spring 32, and the second fixed platform 23, and its upper and lower ends respectively abut against the first connecting platform and the first fixed platform 22. When the first spring 31 and the second spring 32 are sleeved, their winding directions are opposite, so that the elastic force directions always remain perpendicular.

[0038] Working process:

[0039] Design and manufacture a main body frame 1 of a suitable size according to the size and weight of the wire or busbar to be fixed. First, pass the upper end of the connecting rod 33 through the mounting groove 24 and the through hole, and sequentially sleeve the second spring 32 and the first spring 31 on the connecting rod 33, requiring that the winding directions of the second spring 32 and the first spring 31 are opposite. Threadedly connect the upper end of the connecting rod 33 in the threaded hole so that the positioning platform at the lower end is flush with the lower end face of the fixed base 21, and finally fix the fixed base 21 to the external device. In the initial installation state, the second spring 32 and the first spring 31 are kept in a compressed state.

[0040] When the external device is affected by external force vibration, the connecting rod 33 moves upward under the influence until the positioning table abuts against the installation groove 24. When the connecting rod 33 moves upward under the influence, the first spring 31 and the second spring 32 can absorb and disperse the vibration energy, reducing the impact of vibration on the wire or busbar. At the same time, since the first spring 31 and the second spring 32 have opposite helix directions when sleeved, when the connecting rod 33 tilts, the first spring 31 and the second spring 32 can cancel each other's inclined elastic forces, so that the resultant force of the elastic forces of the two springs always remains perpendicular. The strong structure of the main frame 1 ensures that the fixing effect can still be maintained in extreme cases, preventing the device from falling off.
