[0027] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0028] In the present utility model, unless otherwise stated, directional words such as "upper, lower, inside, outside" contained in a term merely represent the orientation of the term in normal use, or are common names understood by those skilled in the art, and should not be regarded as limitations on the term.

[0029] like Figure 1-6 As shown, an adjustable transformer winding skeleton, the winding skeleton comprises: a first end limit plate 1, a second end limit plate 2 arranged parallel to the first end limit plate 1, a first sleeve 3 fixedly arranged on the first end limit plate 1, and a second sleeve 4 fixedly arranged on the second end limit plate 2 and having the same cross section as the first sleeve 3 and arranged in the same length direction as the first sleeve 3, the end of the first sleeve 3 away from the first end limit plate 1 is connected to the end of the second sleeve 4 away from the second end limit plate 2;

[0030] At least one middle partition plate detachably mounted on the outside of the first sleeve 3 or the second sleeve 4 is arranged between the first end limit plate 1 and the second end limit plate 2, and the middle partition plate is composed of a pair of partition plates 5 connected by clamping, and at least one partition plate 5 is protrudingly provided with a clamping block portion 6, and the outer walls of the first sleeve 3 and the second sleeve 4 are both recessed with a plurality of first mounting grooves 7 arranged at intervals along their own length direction and matching the clamping block portion 6.

[0031] When a single-slot winding skeleton is needed, the middle partition can be removed, and the coil can be wound on the first sleeve 3 and the second sleeve 4; when a double-slot winding skeleton is needed, the middle partition is installed on the first sleeve 3 or the second sleeve 4, and the block part 6 can be installed in different first installation grooves 7, and the size of the double slots can be adjusted according to actual use requirements, which is highly practical; multiple middle partitions can also be arranged between the first end limit plate 1 and the second end limit plate 2, which can be used as a multi-slot winding skeleton.

[0032] When the middle partition is installed on the first casing 3 or the second casing 4, it can also be used as a single-slot winding skeleton, and the winding space can be adjusted by adjusting the position of the middle partition.

[0033] A plurality of first clamping grooves 8 are recessed on the inner wall of the first sleeve 3 away from the first end stop plate 1, and a plurality of first clamping members 9 are arranged on the inner wall of the second sleeve 4 away from the second end stop plate 2, which can be inserted into the plurality of first clamping grooves 8 one by one.

[0034] The winding skeleton also includes at least one middle sleeve 10 with a cross-section identical to that of the first sleeve 3, and a plurality of second clips 11 that can be inserted one-to-one into the plurality of first clip grooves 8 are provided on the inner wall at one end of the middle sleeve 10, and a plurality of second clip grooves 12 that are recessed on the inner wall at the other end of the middle sleeve 10 for the plurality of first clips 9 to be inserted one-to-one into.

[0035] The middle sleeve 10 can increase the maximum distance between the first end limit plate 1 and the second end limit plate 2, thereby increasing the size of the winding space.

[0036] Because the first clip 9 can be inserted into the first clip groove 8, and the second clip 11 can be inserted into the first clip groove 8, the first clip 9 can also be inserted into the second clip groove 12, so when there are multiple middle sleeves 10, the second clip 11 on the middle sleeve 10 can be inserted into the second clip groove 12 of the adjacent middle sleeve 10.

[0037] The outer wall of the middle casing 10 is recessed with a plurality of second mounting grooves 13 which are arranged at intervals along the length direction thereof and can accommodate the block portion 6 to be inserted.

[0038] The middle partition can also be installed in the second installation groove 13, thereby increasing the adjustment range of the middle partition.

[0039] The partition plate 5 is in a U shape, one end of the partition plate 5 is recessed with a snap-fitting notch 14 , and the other end of the partition plate 5 is protruding with a snap-fitting portion 15 that can be inserted into the snap-fitting notch 14 of another partition plate 5 .

[0040] When the middle partition needs to be installed on the first sleeve 3, the second sleeve 4 or the middle sleeve 10, the snap-in notch 14 of the partition plate 5 is aligned with the snap-in portion 15 of another partition plate 5, the pair of partition plates 5 are pushed closer to each other, and the block portion 6 is aligned with the first mounting groove 7 or the second mounting groove. After the snap-in portion 15 is inserted into the snap-in notch 14, the pair of partition plates 5 are combined together, and the snap-in portion 15 will also be inserted into the corresponding first mounting groove 7 or the second mounting groove 13.

[0041] A positioning groove 16 is recessed on the end surface of one end of the partition plate 5 , and a positioning protrusion 17 that can be inserted into the positioning groove 16 of another partition plate 5 is protruded on the end surface of the other end of the partition plate 5 .

[0042] The function of the positioning protrusion 17 and the positioning groove 16 is to prevent the pair of partition plates 5 from being misaligned along the length direction of the first sleeve body 3 after the pair of partition plates 5 are snapped together.

[0043] The recessed portion on the end of the partition plate 5 close to the snap-fitting notch 14 is conducive to the snap-fitting portion 15 being snapped into the inclined transition portion 18 in the snap-fitting notch 14 .

[0044] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, the technical solution of the present invention can be subjected to a variety of simple modifications, and these simple modifications all belong to the protection scope of the present invention.

[0045] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present utility model will not further describe various possible combinations.

[0046] In addition, various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention.
