DETAILED DESCRIPTION

[0035] The following will be combined with the attached embodiment of the utility model Figure 1-7 , 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 them. Based on the embodiments of 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.

[0036] Example:

[0037] like Figures 1 to 7 As shown, a universal dry-type transformer spacer includes a bottom block 11, a stacking block 14 is placed above the bottom block 11, a plurality of connecting plugs 15 are integrally formed at the upper end of the bottom block 11, a plurality of first slots 16 are opened at the lower end of the stacking block 14, and the connecting plugs 15 are inserted into the first slots 16;

[0038] A top block 17 is placed on the upper end of the stacking block 14, and a partition plate 12 is fixedly connected to the inner side of the top block 17. The partition plate 12 is used to separate the high and low voltage coils and fix the insulating cylinder in the dry-type transformer. A stacking block 14 is placed above the stacking block 14, and the technician can stack multiple stacking blocks 14 according to actual conditions to adapt to various assembly conditions. In order to facilitate intuitive observation of the connection between the stacking block 14 and the bottom block 11 and the top block 17 in the drawings of the specification, only one stacking block 14 is stacked;

[0039] The upper end of the bottom block 11 is integrally formed with a plurality of connecting plug blocks 15, the lower end of the stacking block 14 is provided with a plurality of first slots 16, the connecting plug blocks 15 are inserted into the first slots 16, a top block 17 is placed on the upper end of the stacking block 14, the upper end of the stacking block 14 is integrally formed with a plurality of upper plug blocks 18, the lower end of the top block 17 is provided with a plurality of second slots 19, the upper plug blocks 18 are inserted into the second slots 19;

[0040] In addition, a sliding plate 20 is symmetrically arranged at the upper end of the top block 17 , a supporting component is arranged between the sliding plate 20 and the top block 17 , and a locking component for fixing the sliding plate 20 is provided on the top block 17 .

[0041] The working principle of the utility model is as follows: when assembling the universal dry-type transformer spacer, at least one of the stacking blocks 14 is stacked on the bottom block 11 according to the actual assembly situation. After the stacking of the stacking blocks 14 is completed, the top block 17 is inserted at the upper end of the stacking block 14, and then the sliding plate 20 is extended to a suitable length to the left and right according to the size of the upper transformer component, and the locking assembly is used to fix the sliding plate 20 to prevent the sliding plate 20 from sliding to the left and right after the transformer is assembled. After the sliding plate 20 is fixed, the structural strength of the sliding plate 20 is strengthened by the supporting assembly to ensure the overall assembly stability of the transformer.

[0042] The upper end of the top block 17 is symmetrically provided with sliding grooves 23, the sliding plate 20 is slidably connected in the sliding grooves 23, and the lower end of the sliding grooves 23 is provided with a limiting groove 24, the lower end of the sliding plate 20 is fixedly connected with a limiting slider 25, and the limiting slider 25 is slidably connected in the limiting groove 24, and the sliding plate 20 is limited by the limiting slider 25 to prevent the sliding plate 20 from falling off from the sliding groove 23.

[0043] The support assembly includes a hinged rod 27, and the specific connection method of the support assembly is: a hinged part 28 is fixedly connected to the side wall of the top block 17, one end of the hinged rod 27 is hinged to the hinged part 28, and a plurality of slots 29 are provided at the lower end of the sliding plate 20, and the other end of the hinged rod 27 is inserted into the slot 29.

[0044] Taking the sliding plate 20 located on the left side of the top block 17 as an example, the working principle of the support assembly is as follows: in a natural state, the hinge rod 27 naturally hangs on both sides of the top block 17 to avoid occupying excess storage space. After the technician moves the sliding plate 20 to a suitable length, the sliding plate 20 is first dragged to the left so that the hinge rod 27 is located in the center of the slot 29, and then the hinge rod 27 is extended into the slot 29, and then the sliding plate 20 is retracted to the right to fix the hinge rod 27 in the slot 29. A triangular structure is formed between the hinge rod, the sliding plate 20 and the top block 17 to strengthen the structural strength of the sliding plate 20, and then the locking assembly is used to fix the sliding plate 20;

[0045] When the sliding plate 20 needs to be retracted, the sliding plate 20 is first slid to the right. During this stroke, the hinged rod 27 is driven to rotate clockwise by a certain angle and is located in the center of the slot 29. Then, the hinged rod 27 is rotated counterclockwise to leave the slot 29.

[0046] It should be noted that the sliding plate 20 located on the right side of the top block 17 has an operation direction opposite to that of the sliding plate 20 on the left side during assembly and disassembly.

[0047] In addition, a rounded corner is provided between one end of the hinge rod 27 inserted into the slot 29 and the side wall of the hinge rod 27 , so as to facilitate the insertion of the hinge rod 27 into the slot 29 .

[0048] The locking assembly includes a locking tooth block 32 and a threaded shaft 33. The specific connection method of the locking assembly is: a movable groove 34 is opened on one side of the sliding groove 23, and the locking tooth block 32 is slidably connected in the movable groove 34 forward and backward, and a plurality of locking teeth 36 are fixedly connected to the locking tooth block 32 on the side facing the sliding plate 20, and a matching tooth 37 is provided on the side of the sliding plate 20 facing the locking teeth 36, and the locking teeth 36 are meshedly connected to the matching teeth 37. A threaded hole 35 that passes through the rear side wall of the top block 17 is opened on the side wall of the sliding groove 23, and the threaded shaft 33 is threadedly connected in the threaded hole 35, and the threaded shaft 33 is rotatably connected to the locking tooth block 32.

[0049] The working principle of the locking assembly is as follows: in the original state, the locking tooth block 32 is away from the sliding plate 20, the locking tooth 36 is not engaged with the matching tooth 37, and the sliding plate 20 can slide freely in the sliding groove 23. When the technician extends the sliding plate 20 outward to a suitable length, the threaded shaft 33 is rotated to make the threaded shaft 33 approach the sliding plate 20 until the locking tooth 36 is engaged with the matching tooth 37, thereby achieving the purpose of the sliding plate 20 and preventing the sliding plate 20 from sliding left and right when assembling the transformer or after the transformer is assembled.

[0050] In addition, a buffer air cushion 30 is fixedly connected inside the stacking block 14, and an air cavity 31 is opened in the buffer air cushion 30. Vents 38 are opened at both left and right ends of the air cavity 31. Through the above structure, when technicians place components such as coil groups on the universal dry-type transformer pad, the sinking pressure generated by the components can be buffered, thereby increasing the structural strength of the universal dry-type transformer pad and ensuring that the universal dry-type transformer pad can provide stable support for the coil group.

[0051] In addition, a plurality of expansion cavities 39 for increasing the air content of the air cavity 31 are symmetrically opened in the air cavity 31, so that the size of the air cavity 31 is larger than the size of the vent 38. While increasing the air content in the air cavity 31, the speed of air outflow when the air cavity 31 is squeezed is reduced to achieve a damping effect.

[0052] It should be noted here that the above-mentioned parts are all made of insulating materials.

[0053] It should also be pointed out that the terms used in the present invention, such as "front", "rear", "vertical", "horizontal", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are only used to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction.
