[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.
[0021] As Figures 1-6As shown in the figure, the utility model discloses a dry-type transformer cushion block, including cushion block 1. A connecting component is provided on the cushion block 1. The connecting component includes an inserting block 2, a screw 3, a spring A 4 and a magnet 5. Rotating grooves 6 penetrating the bottom wall are formed on the left and right side walls of the cushion block 1. After the inserting block 2 is inserted into the rotating groove 6, it is rotatably connected to the cushion block 1 through a rotating shaft. A threaded hole 7 is formed through the cushion block 1 up and down. The screw 3 is screwed into the threaded hole 7 and is threadedly connected to the cushion block 1. The height of the screw 3 is two-thirds of the height of the cushion block 1. A slot 8 is formed on the top wall of the cushion block 1. Telescopic holes 9 are formed on the front and rear side walls of the slot 8. The spring A 4 and the magnet 5 are respectively located inside the telescopic hole 9 and the slot 8. One end of the spring A 4 is fixedly connected to the side wall of the telescopic hole 9, and the other end of the spring A 4 is fixedly connected to the magnet 5. Magnetic attraction grooves 10 are formed on the front and rear side walls of the inserting block 2, and iron sheets are fixedly arranged on the side walls of the magnetic attraction grooves 10. When the cushion block 1 needs to be installed, rotate the inserting block 2 to make it located inside the rotating groove 6, so that the inserting block 2 is magnetically attracted and connected to the magnetic plate 18 on the side wall of the rotating groove 6 to complete the storage of the inserting block 2, and then install the cushion block 1 on the transformer; when the height of the cushion block 1 needs to be adjusted, rotate the inserting block 2 to make it located below the cushion block 1, place another cushion block 1 below the inserting block 2, and insert the inserting block 2 into the slot 8 on another cushion block 1. Since the spring A 4 and the magnet 5 are respectively located inside the telescopic hole 9 and the slot 8, magnetic attraction grooves 10 are formed on the front and rear side walls of the inserting block 2, and iron sheets are fixedly arranged on the side walls of the magnetic attraction grooves 10. After the inserting block 2 is inserted into the slot 8 and the telescopic hole 9 is aligned with the magnetic attraction groove 10, the magnet 5 will be ejected into the magnetic attraction groove 10 by the spring A 4 and magnetically attracted and connected to the iron sheet inside the magnetic attraction groove 10 to fix the two cushion blocks 1. At this time, the threaded holes 7 of the two cushion blocks 1 are aligned, and the screw 3 is screwed into the threaded hole 7 of another cushion block 1. Since the height of the screw 3 is two-thirds of the height of the cushion block 1, each half of the screw 3 is located inside the two cushion blocks 1, which plays a role in completely fixing the two cushion blocks 1. To sum up, the utility model adjusts the height of the cushion block 1 by splicing a plurality of cushion blocks 1, has the beneficial effect of conveniently and flexibly adjusting the height of the cushion block 1, and solves the problem that the height of the traditional dry-type transformer cushion block 1 can only be adjusted by replacing the whole cushion block 1, resulting in inconvenient and inflexible adjustment of the height of the cushion block 1.
[0022] Preferably, the connecting component further includes a spring B 11 and a baffle 12 located inside the slot 8. One end of the spring B 11 is fixedly connected to the bottom wall of the slot 8, the other end of the spring B 11 is fixedly connected to the baffle 12, and the top wall of the baffle 12 is flush with the top wall of the cushion block 1. Since one end of the spring B 11 is fixedly connected to the bottom wall of the slot 8, the other end of the spring B 11 is fixedly connected to the baffle 12, and the top wall of the baffle 12 is flush with the top wall of the cushion block 1, it plays a role in preventing external impurities from entering the inside of the slot 8; when the inserting block 2 is inserted into the slot 8, the inserting block 2 will squeeze the baffle 12 to make the spring B 11 contract, which does not affect the installation of the inserting block 2.
[0023] Preferably, guide blocks 13 are fixedly arranged on both the front and rear sides of the baffle 12. Guide grooves 14 matching the guide blocks 13 are formed on the front and rear side walls of the slot 8. The guide blocks 13 are inserted into the guide grooves 14 and are in contact connection with the cushion block 1. Since the guide blocks 13 are inserted into the guide grooves 14 and are in contact connection with the cushion block 1, when the baffle 12 is squeezed by the insertion block 2, it will move, playing a role in guiding the baffle 12 when it moves and preventing the baffle 12 from tilting.
[0024] Preferably, the connection assembly further includes an elastic pad 15. A plurality of mounting posts 16 are fixedly arranged on the elastic pad 15. A plurality of mounting holes 17 are formed on both the upper and lower side walls of the cushion block 1. The mounting posts 16 and the mounting holes 17 are in interference fit. Since a plurality of mounting posts 16 are fixedly arranged on the elastic pad 15 and a plurality of mounting holes 17 are formed on both the upper and lower side walls of the cushion block 1, after the cushion blocks 1 are spliced, the elastic pad 15 is placed on both the upper and lower sides of the cushion block 1, and then the mounting posts 16 are inserted into the mounting holes 17. Since the mounting posts 16 and the mounting holes 17 are in interference fit, the elastic pad 15 is not easily dropped. After the elastic pad 15 is installed, it plays a role in buffering and shock absorption.
[0025] Preferably, both the magnet 5 and the magnetic attraction groove 10 are provided with rounded corners. Since both the magnet 5 and the magnetic attraction groove 10 are provided with rounded corners, it plays a role in facilitating the insertion of the magnet 5 into the magnetic attraction groove 10.
[0026] Preferably, a magnetic plate 18 is fixedly arranged on the side wall of the rotating groove 6. Iron sheets are fixedly arranged on both the left and right side walls of the insertion block 2. Since iron sheets are fixedly arranged on both the left and right side walls of the insertion block 2, the insertion block 2 is rotated to be located inside the rotating groove 6, so that the insertion block 2 is magnetically attracted and connected to the magnetic plate 18 on the side wall of the rotating groove 6, playing a role in storing the insertion block 2.
[0027] Preferably, a picking groove 19 is formed on the insertion block 2. Since the picking groove 19 is formed on the insertion block 2, it plays a role in facilitating the picking out of the insertion block 2 from the rotating groove 6.
[0028] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
