[0024] The following combination Figure 1-3 The specific embodiment of the utility model is described, which is a transformer core fixing and transportation tool, comprising:
[0025] The left bracket 1 is a U-shaped structure, and a connecting rod 11 is fixed to one side of the bottom of the left bracket 1. A limiting hole 111 is provided on the connecting rod 11;
[0026] The right bracket 2 is provided with a telescopic rod 21 on one side of its top that slides with the connecting rod 11, and the telescopic rod 21 is provided with a locking plate 211 for mutual locking between the connecting rod 11 and the telescopic rod 21. The sliding cooperation between the connecting rod 11 and the telescopic rod 21 realizes the adjustable distance between the left bracket 1 and the right bracket 2 to adapt to the needs of fixed transportation of iron cores of different sizes. The adjustment of the distance between the connecting rod 11 and the telescopic rod 21 can be achieved by mutual locking between the locking plate 211 and the limiting hole 111. The locking plate 211 is rotated and matched with the thread 301 on the telescopic rod 21, so that one end of the locking plate 211 abuts against the limiting hole 111 to realize the locking of the bottom after the position adjustment between the left bracket 1 and the right bracket 2;
[0027] The limiter 3 includes a first sleeve 31 fixedly provided on the left bracket 1 and a second sleeve 32 fixedly provided on the right bracket 2. The first sleeve 31 cooperates with the second sleeve 32 thread 301. The limiter 3 is used for locking the left bracket 1 and the right bracket 2 after the distance between the left bracket 1 and the right bracket 2 is adjusted to improve the locking stability between the left bracket 1 and the right bracket 2.
[0028] Please refer to Figure 1 、 Figure 3As shown, the telescopic rod 21 is sleeved on the connecting rod 11, the locking plate 211 cooperates with the thread 301 of the telescopic rod 21, and one end thereof abuts against the limiting hole 111, and the telescopic rod 21 is extended and retracted on the connecting rod 11 to realize the adjustable distance between the left bracket 1 and the right bracket 2 to adapt to the needs of fixed transportation of iron cores of different sizes. After adjusting the relative positions between the left bracket 1 and the right bracket 2, the locking plate 211 is cooperated with the thread 301 of the telescopic rod 21 to move its bottom toward the side of the connecting rod 11, and finally one end of the locking plate 211 abuts against the limiting hole 111 opened on the connecting rod 11, thereby limiting the mutual telescopic movement between the connecting rod 11 and the telescopic rod 21.
[0029] Please refer to Figure 1-Figure 2 As shown, the limiting hole 111 is provided with a plurality of limiting holes 111, and the plurality of limiting holes 111 are equidistantly distributed along the length direction of the connecting rod 11, and the locking plate 211 abuts against one of the limiting holes 111. The plurality of limiting holes 111 are used to meet the locking requirements after adjustment of different positions between the left bracket 1 and the right bracket 2, so as to meet the requirements for fixed transportation of iron cores of different sizes.
[0030] Please refer to Figure 1 As shown, a positioning plate 13 is fixed on the opposite side of the left bracket 1 and the right bracket 2, and a waist-shaped groove 14 is provided on the positioning plate 13. A sliding rod 15 is provided in the waist-shaped groove 14. The sliding fit of the sliding rod 15 in the waist-shaped groove 14 can improve the stability of the left bracket 1 and the right bracket 2 after the position is adjusted, wherein a groove is provided on one side of the waist-shaped groove 14, and the groove can realize the relative locking of the sliding rod 15 after sliding.
[0031] Please refer to Figure 1 As shown, a positioning rod 30 is provided on the left bracket 1 and the right bracket 2, and one end of the positioning rod 30 is fixedly connected to the left bracket 1 or the right bracket 2, and a first limiting rod 12 is slidably provided on the positioning rod 30 on the left bracket 1, and a second limiting rod 22 is slidably provided on the positioning rod 30 on the right bracket 2, and the second limiting rod 22 is sleeved on the first limiting rod 12, and the positioning rod 30 on the right bracket 2 is sleeved with a second limiting rod 22, and the second limiting rod 22 can move up and down along the positioning rod 30. The positioning rod 30 fixedly connected to the left bracket 1 is sleeved with a first limiting rod 12, and the first limiting rod 12 can adjust the upper and lower positions along the positioning rod 30 on the left bracket 1. At the same time, the second limiting rod 22 can telescopically move along the first limiting rod 12, and the telescopic cooperation between the first limiting rod 12 and the second limiting rod 22 is utilized to realize the mutual locking between the left bracket 1 and the right bracket 2 after adjustment.
[0032] Please refer to Figure 1-Figure 3As shown, a thread 301 is formed on the positioning rod 30, and the thread 301 on the thread 301 cooperates with a limiting bolt 302, and the limiting bolt 302 is used to limit the installation height of the first limiting rod 12 or the second limiting rod 22 on the positioning rod 30. Since the first limiting rod 12 and the second limiting rod 22 are sleeved on the positioning rod 30, the thread 301 on the positioning rod 30 is cooperated with the limiting bolt 302 to limit the first limiting rod 12 or the second limiting rod 22 from moving upward along the height direction of the positioning rod 30, so that the iron core is fixed between the first limiting rod 12 or the second limiting rod 22 and the bracket to limit the position of the iron core on the fixed tooling to avoid moving up and down.
[0033] Please refer to Figure 1 、 Figure 3 As shown, internal threads 301 are formed in the first sleeve 31 and the second sleeve 32. The internal threads 301 in the first sleeve 31 and the second sleeve 32 are distributed in opposite directions. The internal threads 301 of the first sleeve 31 and the second sleeve 32 are used to adjust the position therebetween. By matching the synchronous threads 301 of the first sleeve 31 and the second sleeve 32 to a screw 33, the distance between the first sleeve 31 and the second sleeve 32 can be adjusted by rotating the screw 33.
[0034] Please refer to Figure 3 As shown, a screw 33 is provided between the first sleeve 31 and the second sleeve 32, and the screw 33 cooperates with the synchronous threads 301 of the first sleeve 31 and the second sleeve 32. An adjusting bolt 34 is fixed on the screw 33. Since the threads 301 on the first sleeve 31 and the second sleeve 32 are in opposite directions, and the screw 33 cooperates with the synchronous threads 301 of the first sleeve 31 and the second sleeve 32, the position between the first sleeve 31 and the second sleeve 32 is adjusted by rotating the adjusting bolt 34 fixed on the screw 33, so that the two are closer to or farther away from each other, thereby changing the distance between the left bracket 1 and the right bracket 2, and adjusting the lateral support of the iron core to adapt to the reinforcement and transportation requirements of iron cores of different sizes.
[0035] Working principle of this utility model:
[0036] The locking plate 211 on the telescopic rod 21 releases the limit on the connecting rod 11. At the same time, the screw rod 33 is forced to rotate by rotating the adjusting bolt 34, so that the two ends of the screw rod 33 are synchronously engaged with the first sleeve 31 and the second sleeve 32 to form threads 301, thereby changing the distance between the left bracket 1 and the right bracket 2.
[0037] According to the actual size of the iron core, the adjusting bolt 34 is rotated to force the positioning rods 30 fixed on the left bracket 1 and the right bracket 2 to be close to the side surface of the iron core until the adjusting bolt 34 cannot be rotated. During the rotation of the adjusting bolt 34, the first sleeve 31, the first limiting rod 12 and the second limiting rod 22 are synchronously telescoped and matched, and the connecting rod 11 and the telescopic rod 21 at the bottom are telescoped with each other, finally achieving that the positioning rods 30 on both sides are close to the side surface of the iron core. When the left bracket 1 and the right bracket 2 approach or move away from each other, one end of the sliding rod 15 in the waist-shaped groove 14 moves along the waist-shaped groove 14 to improve the stability of the left bracket 1 and the right bracket 2 after the position adjustment. After the mutual position of the left bracket 1 and the right bracket 2 is adjusted, the position of the sliding rod 15 can be locked in the waist-shaped groove 14 to prevent the position of one end of the sliding rod 15 from moving.
[0038] After the position adjustment of the connecting rod 11 and the second limiting rod 22 is completed, the locking plate 211 is inserted into one of the limiting holes 111 and the locking plate 211 is rotated so that the thread 301 engages with the telescopic rod 21. When the thread 301 engages, the other end abuts against one of the limiting holes 111, thereby locking the relative positions of the connecting rod 11 and the telescopic rod 21.
[0039] According to the height fixation requirement of the iron core, the first limit rod 12 and the second limit rod 22 are moved to fit with the top of the iron core, and the limit bolt 302 is rotated to make it engage with the thread 301 on the upper end of the positioning rod 30, so that the height of the first limit rod 12 and the second limit rod 22 are limited by the limit bolt 302, thereby preventing the iron core from moving along the height direction of the positioning rod 30, thereby improving the stability of the iron core reinforcement.

For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.
