DETAILED DESCRIPTION

[0029] The following are only preferred embodiments of the present invention, and do not limit the protection scope of the present invention. The directional words such as "upper", "lower", "left", and "right" in the embodiments are only limited to the visual reference of the drawings and are not specific.

[0030] See also Figure 1-Figure 6 As shown, a transformer core assembly that is easy to fasten includes a core body 1 and a core clamping assembly 2. Figure 1-3 The core body 1 is composed of a horizontally arranged upper core yoke 11 and a lower core yoke 12, and a core column 13 vertically arranged between the upper core yoke 11 and the lower core yoke 12. The upper core yoke 11, the lower core yoke 12 and the core column 13 are respectively made of stacked steel sheets. An insulating shell 14 is also wrapped around the outer periphery of the core column 13, and the insulating shell 14 is made of insulating material.

[0031] See also Figure 1-3The core clamping assembly 2 is clamped on the outer periphery of the core body 1, and is used to clamp and tighten the core body 1. The core clamping assembly 2 includes two clamping blocks 21 and four first connecting rods 22. The two clamping blocks 21 are respectively arranged above the core upper yoke 11 and below the core lower yoke 12. A plurality of ear plates 23 are correspondingly arranged on the outer sides of the two clamping blocks 21, and each corresponding two ear plates 23 arranged on the two clamping blocks form a group. Each group of ear plates 23 is connected by a first connecting rod 22, and the first connecting rod 22 is connected to the two ends of the two ear plates 23 and is locked and fixed by nuts 24. The two clamping blocks 21 can clamp the core body 1 in the vertical direction.

[0032] See also Figure 1-3 , two vertically and symmetrically arranged fastening plates 25 are installed on a side surface of each clamping block 21 close to the core body 1. A first slide groove 211 is arranged in each clamping block 21, and the first slide groove 211 is arranged along the width direction of the clamping block 21. A first slider 251 is formed at the bottom of each fastening plate 25, and the first slider 251 can be slidably inserted in the first slide groove 211. The two fastening plates 25 installed on each clamping block 21 can slide relatively in translation within the length range of the first slide groove 211. The fastening plates 25 are arranged along the length direction of the clamping block 21.

[0033] Further, see Figure 2-5 On each clamping block 21, a first connecting frame 26 and a second connecting frame 27 are respectively provided on the outer sides of both ends of the fastening plate 25 for sliding and positioning the fastening plate 25. Specifically:

[0034] See also Figure 4 The first connecting frame 26 includes a first supporting block 261, a first screw rod 262, a first sliding sleeve 263 and two first connecting rods 264. The first supporting block 261 is vertically arranged and its bottom end is fixedly connected to the clamping block 21. The first screw rod 262 is horizontally arranged on the outward side of the first supporting block 261, and one end of the first screw rod 262 is rotatably inserted on the first supporting block 261. The first sliding sleeve 263 is provided with a through internal threaded hole, and the first screw rod 261 is inserted into the internal threaded hole of the first sliding sleeve 263 and the two are threadedly connected. One end of the two first connecting rods 264 is rotatably hinged to one end of the two fastening plates 25, and the other ends of the two first connecting rods 264 away from the fastening plates 25 are rotatably hinged to the first sliding sleeve 263, and the two first connecting rods 264 are symmetrically arranged along the central axis of the first sliding sleeve 263. A limiting nut (not shown) is also threadedly connected to the first screw rod 262 , and the first sliding sleeve 253 is located between the limiting nut (not shown) and the first supporting block 261 .

[0035] The positions of the first connecting frames 26 on the upper and lower clamping blocks 21 are correspondingly arranged. A vertically arranged pulley 266 is fixedly connected to one end of the upper and lower first screw rods 262 away from the fastening plate 25, and a belt 267 provided thereon is tensioned between the pulleys 266 of the two first screw rods 262.

[0036] See also Figure 5 The second connecting frame 27 includes a second support block 271, a second slide bar 272, a second sliding sleeve 273 and two second connecting rods 274. The second support block 271 is vertically arranged and its bottom end is fixedly connected to the clamping block 21. The second slide bar 272 is horizontally arranged and one end of it is fixedly connected to the outward side of the second support block 271. The second sliding sleeve 272 is provided with a through hole, and the second slide bar 273 is inserted into the through hole of the second sliding sleeve 272 and the two are slidably connected. One end of the two second connecting rods 274 is rotatably hinged to the other end of the two fastening plates 25, and the other end of the two second connecting rods 274 away from the fastening plates 25 is rotatably hinged to the second sliding sleeve 273, and the two second connecting rods 274 are symmetrically arranged along the central axis of the second sliding sleeve 273.

[0037] The working principle is: by rotating any one of the first screw rods 262, the first sliding sleeve 263 can be horizontally translated along the first screw rod 262. The translation of the first sliding sleeve 263 drives the two first connecting rods 264 hinged thereto to rotate toward each other, so that the angle formed by the two first connecting rods 264 is reduced or increased. When the two first connecting rods 264 rotate in the direction of reducing the angle, the two fastening plates 25 can be driven to move toward each other to clamp the core body 1. At the same time, the two fastening plates 25 move toward each other and also drive the two second connecting rods 274 at the other end to rotate in the direction of reducing the angle. The two second connecting rods 274 rotate toward each other, which drives the second sliding sleeve 273 to move horizontally on the second sliding rod 272. That is, the first connecting frame 26 and the second connecting frame 27 can be linked through the two fastening plates 25 on the same clamping block 21. Since the angle formed by the two first connecting rods 264 toward the core body 1 is an acute angle, and the angle formed by the two second connecting rods 274 toward the core body 1 is also an acute angle, when the effect of clamping the core body 1 is achieved, the limiting nut (not shown in the figure) is pressed against the outside of the first sliding sleeve 263, so as to achieve the purpose of stably clamping the core body 1 in the longitudinal direction.

[0038] Further, see Figure 6, each clamping block 21 is also provided with a second slide groove 252, and the second slide groove 252 is arranged along the length direction of the clamping block 21. Each clamping block 21 is also provided with two symmetrically arranged push plates 28, and the bottom of the two push plates 28 is formed with a second slider 281. The second slider 281 is slidably inserted in the second slide groove 252. The two push plates 28 installed on each clamping block 21 can slide relatively in translation within the length range of the second slide groove 252. The two push plates 28 are arranged along the width direction of the clamping block 21.

[0039] Each clamping block 21 is also provided with a third slide groove 253, which is arranged parallel to the second slide groove 252, and the length of the third slide groove 253 is not less than the length of the second slide groove 252. A second screw rod 254 is rotatably installed in the third slide groove 253. The second screw rod 254 can rotate in the third slide groove 253. The bottom of each push plate 28 is also connected to a sliding block 282, and the sliding block 282 is provided with an internal threaded through hole. The internal threaded through hole of the sliding block 282 is sleeved on the second screw rod 252 and the two are threadedly connected. One end of the second screw rod 252 extends out of the outer end of the clamping block 21 and is connected to a handle block (not shown) for easy handholding. By rotating the second screw rod 252, the two push plates 28 can be translated toward each other, and the purpose of clamping the core body 1 in the lateral direction can be achieved.

[0040] Further, see Figure 7 The core clamping assembly 2 also includes two reinforcing clamping mechanisms 3 for clamping and limiting the fastening plate 25. Each reinforcing clamping mechanism 3 is located on the outer side of the outermost core column 13, and includes two symmetrically arranged guide blocks 31. The guide blocks 31 are vertically arranged and their two ends are respectively connected to the upper and lower clamping blocks 21. A horizontal connecting rod 32 and two clamps 33 are connected between the two guide blocks 31. The two clamps 33 are respectively located on the upper and lower sides of the horizontal connecting rod 32 and are symmetrically arranged. Fourth sliding grooves 35 are respectively opened on the upper and lower sides of the guide blocks 31. The clamp 33 includes a "U"-shaped clamp body 331, and the opening of each clamp body 331 faces the clamping block 21 adjacent thereto; two opposite outer sides of the clamp body 331 are respectively connected with "T"-shaped fourth sliders 332; one end of each fourth slider 332 is fixedly connected to the clamp body 331, and the "T"-shaped head at the other end extends outward and is slidably clamped in the fourth slide groove 35 adjacent thereto. That is, the clamp 33 as a whole can slide up and down in the fourth slide groove 35.

[0041] See also Figure 7The reinforcing clamping mechanism 3 further includes a third connecting frame 34. The third connecting frame 34 includes a third screw rod 341, a third sliding sleeve 342 and a third connecting rod 343. The third sliding sleeve 342 is provided with a through internal threaded hole, and the internal threaded hole of the third sliding sleeve 342 is sleeved on the third screw rod 341 and the two are threadedly connected. The third screw rod 341 is horizontally arranged in an "I" shape, one end of which is rotatably embedded and connected to the outer side of the horizontal connecting rod 32, and the other end extends to the outside and can limit the third sliding sleeve 342 from slipping off. Two third connecting rods 343 are symmetrically arranged on the upper and lower sides of the third sliding sleeve 342, and one end of each third connecting rod 343 is rotatably hinged to the outer side of the third sliding sleeve 342, and the other end is rotatably hinged to the "U"-shaped outer arc surface end of the adjacent clamp body 331.

[0042] The working principle is: after the upper and lower fastening plates 25 clamp the core body 1 in the longitudinal direction, the third screw rod 341 is rotated to simultaneously push the third connecting rods 343 on both sides to rotate, thereby driving the upper and lower clamps 33 to slide relative to each other. When the clamp 33 slides toward the fastening plate 25, the "U"-shaped clamp body 331 will eventually be clamped on the outside of the two fastening plates 25, thereby playing a role in strengthening the clamping of the fastening plates 25 to press the core body 1.

[0043] For further information, see Figure 8 , the assembly also includes a heat dissipation mechanism 4. The heat dissipation mechanism 4 is installed between the upper and lower clamping blocks 21 and is arranged close to the core body 1. The heat dissipation mechanism 4 includes a control module 41, a temperature detector 42, two fans 43 and a heat sink 44. The heat sink 44 is located on one side of the fan 43. The two fans 43 are arranged side by side and are located between the core body 1 and the heat sink 44. The blowing directions of the two fans 43 are opposite, one of which blows toward the core body 1, and the other blows toward the heat sink 43. The control module 41 is electrically connected to the temperature detector 42 and the fan 43, respectively.
