However, the buffer of this structure has problems such as poor stability, unsuitability for long-distance transportation, complex process and high cost. In view of this, a self-locking compact transformer vibration and noise reduction device is proposed. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1-5 The utility model provides a new technical solution: a self-locking compact transformer vibration and noise reduction device, comprising a transformer body 1, a mounting plate 2 fixedly mounted on the lower surface of the transformer body 1, two slots 13 are respectively provided on both sides of the mounting plate 2, and two latch holes 14 are provided on the inner walls of the four slots 13;

[0028] Among them, a buffering noise reduction mechanism is provided on the transformer body 1, which includes a pressure plate 3, a base 4, four hollow columns 5, eight round holes 6, eight round balls 7, four first springs 8, four rings 9, four fixing rods 10, eight grooves 11, four pull rings 12 and eight second springs 15.

[0029] Furthermore, four hollow columns 5 are fixedly mounted on the inner wall of the pressure plate 3 , four first springs 8 are fixedly mounted in the inner walls of the four hollow columns 5 , and four rings 9 are fixedly mounted on the left ends of the four first springs 8 .

[0030] Furthermore, the four fixing rods 10 are fixedly sleeved in the inner walls of the four rings 9, and the four fixing rods 10 are slidably sleeved in the inner walls of the four hollow columns 5;

[0031] Furthermore, four pull rings 12 are fixedly mounted on opposite ends of the four fixing rods 10 , and eight grooves 11 are respectively opened on the outer surfaces of the four fixing rods 10 .

[0032] Furthermore, eight circular holes 6 are respectively opened on the outer surfaces of the four hollow columns 5 , and eight round balls 7 are respectively arranged on the inner surfaces of the eight circular holes 6 .

[0033] Furthermore, eight second springs 15 are respectively fixedly mounted on the lower surface of the pressure plate 3 , and the base 4 is fixedly mounted on the lower ends of the eight second springs 15 ;

[0034] When the self-locking compact transformer vibration and noise reduction device is used, by pulling the pull ring 12, the pull ring 12 drives the left surface fixed on the fixed rod 10 to move upward, and the fixed rod 10 drives the ring 9 fixed on the outer surface to move to the right, and the ring 9 applies pressure to the first spring 8 fixed on the right surface to cause it to shrink. At this time, the two grooves 11 provided on the outer surface of the fixed rod 10 are aligned with the two circular holes 6 provided on the outer surface of the hollow column 5. At this time, the round balls 7 provided in the two circular holes 6 are no longer subjected to the pressure applied by the fixed rod 10. At this time, the round balls 7 are retracted into the hollow column 5. At this time, by inserting the hollow column 5 into the slots 13 provided on the two side surfaces of the mounting plate 2, no tension is applied to the pull ring 12, and at the same time, the first spring 8 When no longer under stress, the first spring 8 expands, and the first spring 8 applies a leftward thrust to the circular ring 9 fixed on the left end. At this time, the circular ring 9 drives the fixed rod 10 fixed on the inner surface to move to the right. At this time, the fixed rod 10 hits the two round balls 7 and applies opposite thrusts to the two round balls 7, causing them to protrude from the hollow column 5 and be snapped into the card hole 14 opened on the inner wall of the slot 13 for fixation. At this time, the installation is completed, and vibrations are generated during the operation of the transformer. The force of these vibrations applies pressure to the pressure plate 3, causing it to move downward. At the same time, this part of the pressure is transmitted to the second spring 15, and the elastic potential energy of the second spring 15 itself is used to buffer the pressure plate 3, reduce its vibration amplitude, and thereby reduce the generation of transformer noise;

[0035] This self-locking compact transformer vibration and noise reduction device and buffer eliminates a force transmission structure, resulting in an overall height of two-thirds that of existing guided transformer buffers. This lowers the product's center of gravity and reduces the overturning moment generated when subjected to external forces, resulting in greater product stability. Furthermore, during long-distance transportation, excessive swaying of the upper load transformer can cause some guide component assemblies to loosen and fall off, potentially damaging the guided buffer or even the upper load transformer. The self-locking compact transformer buffer eliminates the guide component assembly and adopts a self-locking structure, completely resolving this problem. Furthermore, compared to guided transformer buffers, this self-locking compact transformer buffer provides more space for force springs, resulting in a more rational force spring arrangement and more uniform load distribution, improving the buffering effect. Furthermore, compared to guided transformer buffers, this self-locking compact transformer buffer eliminates both a force transmission structure and a guide structure, resulting in a simpler production process, fewer materials and components, lower production costs, and higher economic benefits.

[0036] Working principle: When the self-locking compact transformer vibration and noise reduction device is used, by pulling the pull ring 12, the pull ring 12 drives the fixed rod 10 fixed on the left surface to move upward, and the fixed rod 10 drives the ring 9 fixed on the outer surface to move to the right, and the ring 9 applies pressure to the first spring 8 fixed on the right surface to cause it to shrink. At this time, the two grooves 11 on the outer surface of the fixed rod 10 are aligned with the two circular holes 6 on the outer surface of the hollow column 5. At this time, the round balls 7 set in the two circular holes 6 are no longer subject to the pressure applied by the fixed rod 10. At this time, the round balls 7 are retracted into the hollow column 5. At this time, by inserting the hollow column 5 into the slots 13 on the two side surfaces of the mounting plate 2, no tension is applied to the pull ring 12. At the same time, the first The spring 8 is no longer under stress, and the first spring 8 expands. The first spring 8 applies a leftward thrust to the circular ring 9 fixed at the left end. At this time, the circular ring 9 drives the fixed rod 10 fixed on the inner surface to move to the right. At this time, the fixed rod 10 hits the two balls 7 and applies opposite thrusts to the two balls 7, causing them to protrude from the hollow column 5 and be snapped into the card hole 14 opened on the inner wall of the slot 13 for fixation. At this time, the installation is completed, and vibration is generated during the operation of the transformer. The force of these vibrations applies pressure to the pressure plate 3, causing it to move downward. At the same time, this part of the pressure is transmitted to the second spring 15, and the elastic potential energy of the second spring 15 itself is used to buffer the pressure plate 3, reduce its vibration amplitude, and thereby reduce the generation of transformer noise.

[0037] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
