[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.
[0030] Please see Figure 1-5 This utility model discloses a current transformer mounting structure, including a mounting base 1, which has a mounting groove 11 on its top. The mounting base 1 has an adjustment groove 12 that communicates with the mounting groove 11, and the groove opening 121 extends out of the top surface of the mounting base 1.
[0031] Positioning component 2 includes positioning platform 21, which is disposed at the bottom of current transformer body 01;
[0032] The limiting component 22 is rotatably disposed below the positioning platform 21 and is detachably inserted into the mounting groove 11, with one end slidably inserted into the adjustment groove 12, to prevent the positioning platform 21 from separating from the mounting base 1, thereby positioning the current transformer body 01 on the mounting base 1.
[0033] In practice, when it is necessary to install the current transformer body 01, the mounting base 1 is first set at the predetermined installation position. Then, the operator inserts the positioning platform 21 into the mounting base 1 until its top surface is flush with the top surface of the mounting base 1. At this time, the limiting component 22 extends into the mounting groove 11 along with the positioning platform 21. Then, the operator rotates the limiting component 22 until its corresponding end is inserted into the predetermined position of the adjustment groove 12. At this time, the limiting component 22 prevents the positioning platform 21 from separating from the mounting groove 11, thereby positioning the current transformer body 01 on the top of the mounting base 1. When it is necessary to remove the current transformer body 01, the operator reverses the limiting component 22 until it exits the adjustment groove 12.
[0034] In this invention, through the operation of the positioning component 2, when it is necessary to install the current transformer body 01, the mounting base 1 is first set in the predetermined position, and then the positioning platform 21 is inserted into the mounting groove 11 and the limiting component 22 is rotated until the corresponding end of the limiting component 22 is inserted into the predetermined position of the adjustment groove 12, thereby connecting the current transformer body 01 with the positioning platform 21. When it is necessary to remove the current transformer body 01, the limiting component 22 is reversed until it exits the adjustment groove 12. The disassembly and assembly are convenient and work efficiency is guaranteed.
[0035] In one embodiment, the adjustment groove 12 is arc-shaped;
[0036] The limiting component 22 includes a rotating platform 221, which is coaxially rotatably disposed below the positioning platform 21 and can be detachably inserted into the mounting groove 11, and its outer periphery is adapted to the mounting groove 11.
[0037] The limiting block 222 is disposed on the side wall of the rotating platform 221 and can be slidably inserted into the adjusting groove 12. When the rotating platform 221 rotates, the limiting block 222 rotates with the rotating platform 221 and its rotation trajectory corresponds to the shape of the corresponding adjusting groove 12. When the limiting block 222 is inserted into the adjusting groove 12, it forms an axial lock between the rotating platform 221 and the mounting base 1.
[0038] With this design, when the transformer body 01 needs to be installed, the rotating platform 221 is inserted into the mounting slot 11. At this time, the limiting block 222 enters the adjusting slot 12 through the slot 121. Then, the rotating platform 221 is rotated so that the limiting block 222 is inserted into the predetermined position of the adjusting slot 12. At this time, the limiting block 222 restricts the vertical movement of the positioning platform 21 to prevent the positioning platform 21 from accidentally separating from the mounting base 1.
[0039] It should be noted that the limiting block 222 and the adjusting groove 12 have a sufficient coefficient of friction. Without the influence of external force, the limiting block 222 will not rotate in the adjusting groove 12, so as to avoid the positioning table 21 from accidentally separating from the mounting base 1.
[0040] It should be noted that multiple limiting blocks 222 may be distributed on the side wall of the rotating platform 221, and the mounting base 1 may be provided with adjustment slots 12 corresponding to the number of limiting blocks 222. Each adjustment slot 12 is connected to the mounting slot 11, thereby further improving the stability of the current transformer body 01.
[0041] In one embodiment, a torsion spring (not shown in the figure) is provided at the rotational connection between the rotating platform 221 and the positioning platform 21, and a through hole 13 is also provided on the mounting base 1 to communicate with one end of the adjusting groove 12 away from its groove opening 121;
[0042] The limiting component 22 also includes a constraint member 223, including a constraint block 2231 that is vertically slidably inserted into the top of the limiting block 222. When the constraint block 2231 extends into the through hole 13, the constraint block 2231 is used to constrain the rotation of the rotating table 221.
[0043] A first elastic unit 2232 is also provided between the constraint block 2231 and the limiting block 222, which is used to apply a vertically upward thrust to the constraint block 2231;
[0044] The mounting base 1 is also provided with a reset component 3, one end of which is detachably connected to the constraint block 2231. When the constraint block 2231 extends into the through hole 13, the reset component 3 contacts the constraint block 2231 and can apply a vertical downward thrust to it.
[0045] With this design, when the limiting block 222 enters the adjusting groove 12 through the slot 121, as the rotating table 221 rotates, the constraint block 2231 enters the adjusting groove 12 and is subjected to downward squeezing force. At this time, the first elastic element is compressed until the constraint block 2231 moves above the through hole 13. Then, the first elastic element 2232 loses its constraint and applies an upward elastic force to the constraint block 2231. At this time, the constraint block 2231 slides upward and is inserted into the through hole 13 and is connected to the reset component 3. At this time, the constraint block 2231 is stuck in the through hole 13 to prevent the rotating table 221 from continuing to rotate. At the same time, the torsion spring is compressed to prevent the rotating table 221 from rotating due to external factors, which would cause the transformer body 01 to be accidentally separated from the mounting base 1.
[0046] When it is necessary to remove the transformer body 01, the operator applies downward pressure to the constraint block 2231 through the reset component 3 until it exits the through hole 13. The torsion spring loses its constraint and drives the rotating table 221 to rotate until the limit block 222 moves to the slot 121 position. At this time, the positioning table 21 can be separated from the mounting base 1, making disassembly and assembly convenient.
[0047] Preferably, the first elastic unit 2232 can be a spring from the prior art.
[0048] In one embodiment, the reset component 3 includes a pressure block 31 that is vertically slidably disposed in the through hole 13. When the constraint block 2231 extends into the through hole 13, the constraint block 2231 is connected to the bottom of the pressure block 31 and applies a vertically upward pushing force to it.
[0049] The second elastic unit 32 is disposed in the through hole 13 and located between the pressure block 31 and the mounting base 1. It is used to apply a vertically downward pulling force to the pressure block 31 to prevent the pressure block 31 from separating from the mounting base 1.
[0050] With this design, when the constraint block 2231 extends into the through hole 13, the constraint block 2231 contacts the bottom of the pressure block 31 and applies a vertical upward pushing force to it. At this time, the pressure block 31 is lifted up, and the second elastic unit 32 is stretched. When it is necessary to disassemble the transformer body 01, the operator presses down the pressure block 31. At this time, the pressure block 31 applies a vertical downward squeezing force to the constraint block 2231 until the constraint block 2231 exits the through hole 13. The torsion spring loses its constraint and drives the rotating table 221 to rotate, and the mounting base 1 can exit the mounting groove 11.
[0051] It should be noted that the elastic force of the first elastic unit 2232 is greater than the tensile force of the second elastic unit 32, so as to ensure that the constraint block 2231 can smoothly lift the pressure block 31.
[0052] Preferably, the second elastic unit 32 can be a tension spring as in the prior art.
[0053] In one embodiment, the top surface of the mounting base 1 is provided with a positioning hole 14;
[0054] The bottom of the positioning platform 21 is also provided with a positioning block 211 corresponding to the positioning hole 14. When the positioning platform 21 is connected to the mounting base 1, the positioning block 211 is inserted into the positioning hole 14 to locate the installation position of the current transformer body 01.
[0055] With this design, when the positioning platform 21 is connected to the mounting base 1, the positioning block 211 is inserted into the positioning hole 14, which can also prevent the positioning platform 21 from accidentally rotating the transformer body 01 when positioning the installation position of the transformer body 01.
[0056] In one embodiment, the mounting base 1 has an adjustment port 15 that communicates with the mounting groove 11 on the side closest to the worker.
[0057] With this design, when the rotating platform 221 needs to be adjusted, the operator can apply force to the rotating platform 221 through the adjustment port 15 to make it rotate, which is convenient for adjustment.
[0058] In one embodiment, a protective cover 4 is screwed onto the mounting base 1 and surrounds the pressure block 31 circumferentially to protect the pressure block 31.
[0059] With this design, when the pressure block 31 is lifted by the constraint block 2231, the operator can screw the protective cover 4 onto the mounting base 1 to protect the pressure block 31 and prevent it from moving accidentally due to accidental contact or other factors. When it is necessary to press the pressure block 31, the protective cover 4 can be reversed to separate it from the mounting base 1.
