[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1 and Figure 2 The utility model provides an embodiment: a calibration device with an anti-vibration and shock-absorbing cable bridge, including a bridge body 1 for installing cables, a bottom plate 2 is provided at the bottom end of the bridge body 1, a fixing rod 3 is fixedly connected to the inner wall of the bottom plate 2, the bottom plate 2 and the fixing rod 3 are used to install and fix the bridge body 1, a sphere 4 is fixedly connected to the top of the fixing rod 3, and a fixing block 5 is slidably connected to the outer wall of the sphere 4. When the fixing rod 3 is shaken, the sphere 4 will be driven to slide on the inner wall of the fixing block 5, and the impact force is not directly transmitted to the fixed point on the mounting plate 8, thereby reducing the direct influence of the impact force on the fixed point, the outer wall of the fixing block 5 is fixedly connected to the mounting plate 8, and the bottom end of the mounting plate 8 is fixedly connected to the mounting tube 9.

[0031] Reference Figure 2 and Figure 3 A buffer assembly is provided at the bottom end of the mounting plate 8, and the buffer assembly includes a stabilizing block 61, which is fixedly connected to the outer wall of the fixing rod 3. The stabilizing block 61 fixes the two groups of fixing rods 3, thereby enhancing the stability of the structure. The front and rear ends of the stabilizing block 61 are hinged with a connecting rod 62, and the front end of the connecting rod 62 is hinged with a slider 63. The connecting rod 62 is used to connect the stabilizing block 61 and the slider 63 to transmit the impact force. The outer wall of the slider 63 is slidably connected to the inner wall of the mounting tube 9, and the front end of the slider 63 is fixedly connected with a slide rod 64.

[0032] Reference Figure 1 and Figure 3The outer wall of the front end of the slide rod 64 is slidably connected with a slide cylinder 65, and the gas inside the slide cylinder 65 is squeezed by the slide rod 64 to achieve a certain buffering effect. The slide cylinder 65 is elastically connected to the slider 63 through a compression spring 66, and the buffering performance is improved by the elastic force of the compression spring 66. An exhaust hole 67 is provided at the front end of the mounting cylinder 9 and the slide cylinder 65, and the compressed gas is slowly discharged through the exhaust hole 67 to further improve the buffering effect. Two groups of mounting cylinders 9 are provided, and the two groups of mounting cylinders 9 are symmetrically arranged about the center line symmetry axis of the mounting plate 8.

[0033] Reference Figure 1 and Figure 4 The bridge frame body 1 is provided with two groups, and the two groups of bridge frame bodies 1 are hinged to each other. A correction component is provided on the right side of the bridge frame body 1, and the correction component includes a limit block 71. A V-shaped groove is opened on the right side of the limit block 71, and the position of the protrusion 73 can be limited by the V-shaped groove. The left side of the limit block 71 is fixedly connected to the right side of one group of bridge frame bodies 1, and the left side of the other group of bridge frame bodies 1 is fixedly connected with a slide cylinder 2 72, and the inner wall of the slide cylinder 2 72 is slidably connected with a protrusion 73, and the left side of the protrusion 73 slides on the right side of the limit block 71. The slide cylinder 2 72 is elastically connected to the protrusion 73 by a reset spring 74, and the protrusion 73 is pushed into the inner wall of the V-shaped groove on the limit block 71 by the elastic force of the reset spring 74, thereby correcting the bridge frame body 1.

[0034] Working principle: During use, when the bridge frame body 1 vibrates, the protrusion 73 is driven to slide on the inner wall of the limit block 71, so that the protrusion 73 squeezes the return spring 74 on the inner wall of the slide cylinder 72, and at the same time, the V-shaped groove on the limit block 71 limits the movement of the protrusion 73, and the elastic force of the return spring 74 pushes the protrusion 73 into the inner wall of the V-shaped groove on the limit block 71, so as to correct the bridge frame body 1, so that the bridge frame body 1 can be assisted in being straightened to ensure that it maintains the correct position and posture, which not only improves the stability of the bridge frame.

[0035] At the same time, the bridge body 1 vibrates and drives the fixing rod 3 to swing back and forth, and the fixing rod 3 drives the ball 4 to slide on the inner wall of the fixing block 5. At the same time, the stabilizing block 61 limits the two groups of fixing rods 3, and the stabilizing block 61 drives the connecting rod 62 to squeeze the slider 63.

[0036] The slider 63 drives the slide rod 64 to slide on the inner wall of the slide cylinder 65, squeezing the compression spring 66 and compressing the gas inside the slide cylinder 65 to play a preliminary buffering role. The compressed gas is discharged from the exhaust hole 67 to absorb and disperse the remaining vibration energy again, further reducing the impact of the vibration.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
