This easy-to-maintain and stable-installation voltage transformer includes a mounting base plate, a voltage transformer body, a protective bracket, and a locking mechanism for fixing the voltage transformer body and the protective bracket. During installation, this easy-to-maintain and stable-installation voltage transformer is simple and convenient, saving time and effort.

In later maintenance and repairs, it allows for quick removal of the voltage transformer body and the protective bracket. The protective bracket provides external protection for the voltage transformer body, preventing impacts and ensuring good installation and operational stability.

[0004] While existing technology can fix voltage transformers, it can only fix a single voltage transformer. In practice, multiple voltage transformers may be used together, which requires improvement. Utility Model Content

By setting the fixing component and the rotating component in cooperation, multiple voltage transformer bodies can be fixed at once. By setting the locking component, the clamping plate is prevented from shaking due to vibration generated by the operation of the equipment, so as to maintain the stability of the fixing component. By setting the buffer component, the shaking caused by the operation of the equipment is reduced, thus effectively improving the practicality of the equipment. Attached Figure Description

The fixing base plate 2 is sleeved on the surface of the pre-embedded fixing pin 1, the nut 3 is threadedly connected to the pre-embedded fixing pin 1, the limiting rod 4 is fixedly connected to the upper surface of the fixing base plate 2, the voltage transformer body 5 is sleeved on the surface of the limiting rod 4, the voltage transformer body 5 is placed on the upper surface of the fixing base plate 2, and the fixing mechanism 6 is set on the upper surface of the fixing base plate 2.

[0023] The following section will explain the specific setup and function of its fixing mechanism 6.

[0024] In this embodiment: the fixing mechanism 6 includes a fixing component 61, a rotating component 62, a locking component 63 and a buffer component 64. The fixing component 61 includes a mounting shell 611, which is fixedly connected to the upper surface of the fixing base plate 2. A rotating groove 612 is provided on the mounting shell 611, and a rotating shaft 613 is slidably connected to the inner wall of the rotating groove 612. A clamping plate 614 is fixedly connected to the side of the rotating shaft 613 near the voltage transformer body 5.

[0025] The effect achieved by the above components is to support the rotating shaft 613 and the clamping plate 614 through the mounting shell 611 and the rotating groove 612.

[0026] Specifically, the rotating assembly 62 includes a drive shaft 621, which is rotatably connected to the inner wall of the mounting housing 611, and a driven gear 623 is fixedly connected to the surface of the rotating shaft 613.

[0027] Specifically, a drive gear 622 is fixedly connected to the surface of the drive shaft 621. The drive gear 622 meshes with the driven gear 623. Both the drive gear 622 and the driven gear 623 are located inside the mounting housing 611.

[0028] The effect achieved by the above components is that by setting the fixing component 61 and the rotating component 62 together, multiple voltage transformer bodies 5 can be fixed at one time.

[0029] Specifically, the locking component 63 includes a fixed shaft 632, which is fixedly connected to the side of the mounting housing 611 away from the voltage transformer body 5, and a pawl 633 is rotatably connected to the surface of the fixed shaft 632.

[0030] Specifically, a ratchet 631 is fixedly connected to the surface of the drive shaft 621, the ratchet 631 abuts against the pawl 633, a handwheel 624 is fixedly connected to the surface of the drive shaft 621, and a handle 625 is fixedly connected to the handwheel 624.

[0031] The effect achieved by the above-mentioned components is that the handle 625 makes it more convenient to rotate the handwheel 624.

[0032] Specifically, a fixing block 634 is fixedly connected to the side of the mounting shell 611 away from the voltage transformer body 5, and a traction spring 635 is fixedly connected to the side of the fixing block 634 near the pawl 633. The end of the traction spring 635 away from the fixing block 634 is fixedly connected to the pawl 633.

[0033] The effect achieved by the above components is that by setting the traction spring 635, the pawl 633 is easily supported so that it abuts against the ratchet 631, and when the ratchet 631 rotates, the pawl 633 is reset.

[0034] Specifically, the buffer assembly 64 includes a mounting groove 641, which is located on the side of the clamping plate 614 near the voltage transformer body 5. A support spring 642 is fixedly connected to the inner wall of the mounting groove 641, and a support plate 643 is fixedly connected to the end of the support spring 642 away from the mounting groove 641. The support plate 643 is slidably connected to the inner wall of the mounting groove 641.

[0035] The effect achieved by the above components is to reduce the shaking caused by the operation of the equipment by setting the buffer component 64.

[0036] Working principle: By setting the fixing component 61, it is easy to fix multiple voltage transformer bodies 5 at one time. During installation, the fixing base plate 2 is put on the pre-embedded fixing pin 1, and then the fixing base plate 2 is fixed with the nut 3. Then the voltage transformer body 5 is put on the limiting rod 4, and the handwheel 624 is turned by the handle 625. The handwheel 624 drives the transmission shaft 621 to rotate. The transmission shaft 621 drives the drive gear 622 and ratchet 631 to rotate at the same time. The drive gear 622 drives the driven gear 623 to rotate. The driven gear 623 drives the clamping plate 614 and the buffer component 64 to rotate around the transmission shaft 621 through the rotating shaft 613, so that the clamping plate 614 is in close contact with the voltage transformer body 5.

[0037] By setting the fixing component 61 and the rotating component 62 together, multiple voltage transformer bodies 5 can be fixed at one time. By setting the locking component 63, the clamping plate 614 is prevented from shaking due to the vibration generated by the operation of the equipment, so as to maintain the stability of the fixing component 61. By setting the buffer component 64, the shaking caused by the operation of the equipment can be reduced, thus effectively improving the practicality of the equipment.
