[0002] Thyristors have advantages such as small size, high efficiency and long life. In automatic control systems, they can be used as high-power driving devices to realize the control of high-power equipment by low-power controls. They are widely used in AC and DC motor speed control systems, power control systems and servo systems. Thyristors are usually used by mounting on a mounting bracket.

[0003] Traditional thyristor module mounting brackets mostly adopt a rigid structure design, lacking effective shock-resistant and buffering structures. Rigid connections cannot absorb vibration energy, easily causing vibration stress to be directly transmitted to the thyristor module, thus affecting the use of the thyristor module. Utility Model Content

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Reference Figure 1 - Figure 6 This is an embodiment of the present utility model. This embodiment provides a shock-resistant buffer installation structure for a thyristor module, including a mounting frame 1. The mounting frame 1 is used to support and fix the thyristor module. A base plate 2 is provided below the mounting frame 1. A first buffer component 3 is provided between the base plate 2 and the mounting frame 1.

[0026] The first buffer assembly 3 includes: a connecting rod 31; a limiting plate 32 installed on the outer surface of the connecting rod 31; and an elastic ring 33 installed on the outer surface of the connecting rod 31. The top of the base plate 2 has a first groove 21, and the bottom of the mounting frame 1 has a second groove 11. One end of the connecting rod 31 is movably disposed inside the second groove 11, and the other end of the connecting rod 31 is slidably disposed inside the first groove 21. The elastic ring 33 has a cavity inside, which is filled with silicone. When vibrating, the mounting frame 1 will transmit the vibration impact force to the first buffer assembly 3. The elastic ring 33 itself has a certain elastic shock absorption effect. The silicone combined with the cavity facilitates the improvement of the overall elastic durability of the elastic ring 33, and has a good shock absorption effect. The connecting rod 31 will slowly move downward under the influence of vibration.

[0027] A sliding groove 211 is provided on the inner wall of the first groove 21. A slider 311 is fixedly connected to the outer surface of the connecting rod 31. The slider 311 is slidably connected to the sliding groove 211. When vibration occurs, one end of the connecting rod 31 slides in the second groove 11. At this time, the slider 311 slides synchronously in the sliding groove 211 inside the first groove 21 of the base plate 2. The sliding groove 211 provides a clear sliding path for the slider 311.

[0028] The second groove 11 is threadedly connected to the connecting rod 31 by a first locking bolt 4. The first locking bolt 4 facilitates the fixing of the second groove 11 and the connecting rod 31. Removing the first locking bolt 4 facilitates the separation of the mounting frame 1 from the connecting rod 31.

[0029] The top of the mounting frame 1 has a T-slot 12, and a T-block 5 is slidably connected inside the T-slot 12. A connecting seat 6 is provided above the T-block 5, and a second buffer assembly 7 is provided between the T-block 5 and the connecting seat 6. The top of the connecting seat 6 has a fixing screw hole 61, which facilitates the fixing of the thyristor module. It should be noted that, in order to highlight the innovative elements of this patent, such as how the thyristor module is used, which belongs to the prior art, it will not be described in detail in this patent. By sliding the T-block 5 along the T-slot 12, the connecting seat 6 can be moved to a suitable position, which facilitates the adjustment of the position of the connecting seat 6.

[0030] The second buffer assembly 7 includes a first arc-shaped buffer plate 71 installed at the bottom of the mounting frame 1; a second arc-shaped buffer plate 72 installed at the top of the base plate 2; a slide rod 73 installed between the mounting frame 1 and the base plate 2; and a damping spring 74 disposed on the outer surface of the slide rod 73. The first arc-shaped buffer plate 71 and the second arc-shaped buffer plate 72 are movably connected to the outer surface of the slide rod 73, and the damping spring 74 is disposed between the first arc-shaped buffer plate 71 and the second arc-shaped buffer plate 72. During vibration, the cooperation of the first arc-shaped buffer plate 71, the second arc-shaped buffer plate 72, the slide rod 73 and the damping spring 74 facilitates the buffering of force, improves the buffering effect, and reduces the impact of vibration on the thyristor module.

[0031] Rubber connecting blocks 8 are provided on both sides of the first arc-shaped buffer plate 71 and the second arc-shaped buffer plate 72. Rubber rings 81 are fixedly connected to the upper and lower surfaces of the rubber connecting blocks 8. One set of rubber rings 81 is fixedly connected to the mounting frame 1, and the other set of rubber rings 81 is fixedly connected to the base plate 2. The rubber connecting blocks 8 are fixedly connected between the first arc-shaped buffer plate 71 and the second arc-shaped buffer plate 72. The rubber connecting blocks 8 and the rubber rings 81 constitute an auxiliary shock absorption branch, which works in parallel with the second buffer assembly 7. When vibrating, the rubber rings 81 deform and use their own elasticity to cooperate with the rubber connecting blocks 8, so as to buffer the pressure.

[0032] The connecting seat 6 has fixed feet 62 installed on both sides. The top of the mounting frame 1 has a threaded hole 13. The fixed feet 62 are threadedly connected to the threaded holes 13 by a second locking bolt 9. There are multiple sets of threaded holes 13. The fixed feet 62 are locked in the selected threaded holes 13 by the second locking bolt 9, which makes it easy to fix the position of the connecting seat 6.

[0033] Workflow: The thyristor module is easily fixed by the fixing screw hole 61. By sliding the T-block 5 along the T-slot 12, the connecting seat 6 can be moved to a suitable position, which is convenient for adjusting the position of the connecting seat 6. When there is external vibration, the mounting frame 1 will transmit the vibration impact force to the first buffer component 3. The elastic ring 33 itself has a certain elastic damping effect. The silicone combined with the cavity can improve the overall elastic durability of the elastic ring 33, thereby improving the damping effect. Through the cooperation of the first arc-shaped buffer plate 71, the second arc-shaped buffer plate 72, the slide rod 73 and the damping spring 74, the force can be buffered to reduce the impact of vibration on the thyristor module. That is, the elastic ring 33 of the first buffer component 3 absorbs vibration through silicone, and the damping spring 74 of the second buffer component 7 suppresses shaking. The two work together to reduce the vibration impact on the thyristor module.

[0034] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
