[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] The utility model embodiment discloses an air floating spring transformer damper.

[0026] The utility model provides Figure 1-3 The air floating spring transformer shock absorber shown includes a shock absorber body 1 and an air cavity 2 arranged inside the shock absorber body 1, and is characterized in that a connecting block 3 is fixedly provided on the top of the shock absorber body 1, the interior of the connecting block 3 is hollow, a connecting sleeve 4 is fixedly connected to the top of the connecting block 3, an adjusting tube 5 is provided on the outer sliding sleeve of the connecting sleeve 4, grooves are provided on the upper ends of both sides of the adjusting tube 5, blocks 6 are slidably penetrated in the two grooves, the upper ends of the two blocks 6 away from each other are inclined, a telescopic rod 7 is fixedly provided between the side of the block 6 close to the inner wall of the groove and the groove, a spring 8 is provided on the outer sleeve of the telescopic rod 7, and the two ends of the spring 8 are respectively fixedly connected to the block 6 and the inner wall of the groove.

[0027] When the shock absorber is in use, the shock absorber body 1 is set below the transformer, and the connecting sleeve 4 and the adjusting tube 5 are passed through the mounting hole at the bottom of the transformer. At this time, the inclined surface of the clamping block 6 contacts the inner wall of the mounting hole and is pushed, so that the clamping block 6 squeezes the telescopic rod 7 and the spring 8. After the adjusting tube 5 passes through the mounting hole, the clamping block 8 rebounds and covers the top of the mounting hole under the elastic force recovery of the spring 8. At this time, under the limit of the clamping block 8, the shock absorber body 1 can be connected to the transformer, so that the shock absorber can always stably reduce the vibration of the transformer.

[0028] In order to adjust the setting position of the regulating tube 5 and the clamping block 6 according to the setting position of the transformer, Figure 1-2As shown, a longitudinal adjustment connection mechanism is provided between the connecting block 3 and the adjusting tube 5, and the longitudinal adjustment connection mechanism includes an adjusting screw 9, which is rotatably arranged at the bottom of the inner wall of the connecting block 3, and a slide plate 10 is provided on the sliding sleeve of the rod wall of the adjusting screw 9. Both ends of the slide plate 10 pass through the connecting sleeve 4 and are fixedly connected to the inner wall of the adjusting tube 5. Sliding holes for sliding cooperation with the slide plate 10 are provided on both sides of the outer wall of the connecting sleeve 4. A hanging ring 15 is hingedly provided on the top of the clamping block 6, and a hook 16 for hanging cooperation with the hanging ring 15 is fixedly provided on the inner wall of the groove.

[0029] After the installation position of the transformer is determined, the adjusting screw 9 is rotated to make the slide plate 10 slide along the adjusting screw 9 and move longitudinally while being limited by the sliding hole. At this time, the adjusting tube 5 can drive the block 6 to connect with the mounting hole at the bottom of the transformer. When the shock absorber body 1 needs to be disassembled, the hanging ring 15 can be hung on the hook 16. At this time, the block 6 is squeezed and enters the groove. Then the adjusting tube 5 can be pulled out from the mounting hole, which is convenient for disassembling the shock absorber body 1.

[0030] In order to enable the adjusting screw 9 to rotate stably, Figure 1 As shown, a worm 11 is rotatably penetrated through the side wall of the connecting block 3, a worm wheel 12 is fixedly sleeved at the lower end of the adjusting screw 9, the worm wheel 12 is matched with the worm 11, a rotating block 13 is fixedly sleeved at the end of the worm 11, a positioning bolt 14 is penetrated through the internal thread of the rotating block 13, and a plurality of threaded grooves for matching with the positioning bolts 14 are opened on the outer wall of the connecting block 3.

[0031] When the installation position of the clamping block 6 needs to be adjusted, the rotating block 13 is rotated so that the rotating block 13 drives the worm 11 to rotate. At this time, under the meshing of the worm 11 and the worm wheel 12, the worm wheel 12 drives the adjusting screw 9 to rotate, and after the position of the clamping block 6 is adjusted, the positioning bolt 14 is locked in the thread groove to determine the position of the worm 11 and try to avoid the worm 11 from being accidentally pushed.

[0032] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
