[0002] Instrument transformers are also called instrument transformers, which are the general name for current transformers and voltage transformers. They can convert high voltage into low voltage and high current into low current, and are used for measurement or protection systems. Combination transformers are actually a combination of voltage transformers and current transformers, and are used to measure charges collected by power companies.

[0003] The existing patent with the authorization announcement number "CN212648016U" discloses a combined mutual inductor, including a base, a support rod fixed on the base, the support rod and the base are fixed by a threaded knob, an annular plate fixed on the support rod, a winding drum fixed on the annular plate, a threaded rod provided on the winding drum, a disc fixed on the threaded rod, two symmetrical arc plates fixed on the disc, and a mutual inductor body fixed on the base. The distribution of the winding drum can separate the wires for winding, and the two arc plates can be used to wrap the wound lines. At the same time, the mounting plate can adjust the position to facilitate the installation support of the base according to the actual position;

[0004] However, there are the following deficiencies in this device:

[0005] When the combined mutual inductor is used, it is often damaged by vibration. The above-mentioned device has poor shock absorption ability when in use. When it is vibrated, it will continue to shake. Over time, the mutual inductor is easily damaged by vibration, which reduces the service life of the device. Utility Model Content

Slide grooves are opened on both sides of the top of the base, and sliders are slidably connected to the inner sides of the two groups of the slide grooves. The tops of the two groups of sliders are provided with movable plates, and the tops and bottoms of the two groups of movable plates are sleeved with connecting rods on the sides close to each other. A clamping plate is commonly provided on one side of the two groups of connecting rods on the same side, and springs are sleeved on the outer sides of the two groups of connecting rods. Winding wheels are provided on both sides of the outer side of the rotating rod, and a connecting rope connected to the winding wheel is provided on the side close to the two groups of sliders. Vibration force can be used to strengthen the clamping of the clamping plate to the combined transformer body, thereby improving the damping effect.

[0009] Preferably, guide wheels cooperating with the connecting rope are arranged on both sides of the top of the base close to the slide groove to guide the connecting rope.

[0010] Preferably, a non-slip pad is provided on the side of the clamping plate close to the combined transformer body, which can increase the friction between the clamping plate and the base and enhance the damping effect.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to 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 the embodiments. Based on the embodiments in 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.

[0020] See also Figure 1-4 The utility model provides an embodiment: a shock-absorbing combined mutual inductor, comprising a base 1, guide rods 5 are arranged at the four corners of the top of the base 1, and a combined mutual inductor body 10 is sleeved on the outer sides of the four groups of guide rods 5. Guide grooves 7 matching the guide rods 5 are opened at the four corners of the bottom of the combined mutual inductor body 10, and damping plates 6 are arranged on the tops of the four groups of guide rods 5. A mounting groove 9 is opened in the middle of the bottom of the combined mutual inductor body 10, and a rotating rod 3 is sleeved in the middle of one side of the inner side of the mounting groove 9. Coil springs 4 connected to the mounting groove 9 are arranged on both sides of the outer side of the rotating rod 3, and a gear 8 is arranged in the middle of the outer side of the rotating rod 3. A rack 2 meshing with the gear 8 is arranged in the middle of the top of the base 1, and buffer components are arranged on both sides of the top of the base 1.

[0021] The base 1 in the device is prior art, and the specific structure and principle are not described here.

[0022] Further, the buffer assembly includes a winding wheel 11, a slide groove 12, a connecting rope 13, a slider 14, a movable plate 15, a spring 16, a connecting rod 17 and a clamping plate 18. Slide grooves 12 are provided on both sides of the top of the base 1. Slide grooves 12 are slidably connected to the inner sides of the two groups of slide grooves 12. The tops of the two groups of sliders 14 are provided with movable plates 15. The tops and bottoms of the two groups of movable plates 15 close to each other are sleeved with connecting rods 17. One side of the two groups of connecting rods 17 on the same side is jointly provided with a clamping plate 18. The side of the clamping plate 18 close to the combined transformer body 10 is provided with an anti-slip pad to increase the friction between the clamping plate 18 and the base 1 and enhance the damping effect. A stopper is provided on the side of the connecting rod 17 away from the clamping plate 18 to limit the range of movement of the connecting rod 17. The outer sides of the two groups of connecting rods 17 are sleeved with springs 16.

[0023] Winding wheels 11 are provided on both sides of the outer side of the rotating rod 3, and a connecting rope 13 connected to the winding wheel 11 is provided on one side where the two sets of sliders 14 are close to each other. Guide wheels matching the connecting rope 13 are provided on both sides of the top of the base 1 close to the slide groove 12, which can guide the connecting rope 13. When the rotating rod 3 rotates due to vibration force, the two sets of movable plates 15 can be pulled close together through the connection of the connecting rope 13 to strengthen the clamping force of the splint 18 on the combined transformer body 10, thereby improving the shock absorption effect.

[0024] Furthermore, a connecting block is provided on the outside of the coil spring 4, and the top of the connecting block is connected to the top of the inner side of the mounting groove 9. When the rotating rod 3 rotates, the coil spring 4 can be curled under the limit of the limit block, so that the coil spring 4 cannot rotate with the rotating rod 3.

[0025] Working principle: When the device is used, it can be installed at a designated position. When the device is vibrated and shakes, the combined transformer body 10 can move along the guide of the guide rod 5. At this time, the damping effect of the damping sheet 6 can limit the range of movement of the combined transformer body 10. When the combined transformer body 10 shakes, the engagement of the gear 8 and the rack 2 can drive the rotating rod 3 to rotate. When the rotating rod 3 rotates, the elastic force of the coil spring 4 can buffer the shaking of the combined transformer body 10. With the damping effect of the combined transformer body 10, a shock reduction effect can be achieved.

[0026] When the rotating rod 3 rotates, it can drive the two sets of winding wheels 11 to rotate and reel in the connecting rope 13. At this time, the connecting rope 13 can pull the two sets of sliders 14 to approach each other along the guide of the slide groove 12, thereby driving the two sets of movable plates 15 to approach each other to squeeze the spring 16. The squeezed spring 16 can use its elastic force to push the clamping plate 18 to fit tightly against the side of the combined transformer body 10, thereby improving the clamping effect of the combined transformer body 10, thereby improving the shaking resistance of the combined transformer body 10, reducing the shaking amplitude of the combined transformer body 10, and further improving the shock absorption effect of the device.
