DETAILED DESCRIPTION

[0021] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0022] Example

[0023] like Figure 1-Figure 4 As shown, a transformer core that is easy to install includes a bottom plate 1 and a cover plate 2. A core body 3 is clamped between the bottom plate 1 and the cover plate 2.

[0024] The base plate 1 and the cover plate 2 are both hollow quadrilateral frame shapes. A clamping hole 21 is provided at each of the four corners on the cover plate 2, and a clamping rod 12 extending upward is fixed at each of the four corners on the upper surface of the base plate 1. The four clamping rods 12 and the four clamping holes 21 are respectively arranged around the outer circumference of the core body 3, and the four clamping rods 12 are arranged one by one with the four clamping holes 21. An inner bend hook 121 with an outer diameter slightly larger than the aperture of the clamping hole 21 is formed on the top of the clamping rod 12. The four clamping rods 12 can be inserted into the four clamping holes 21 one by one, and the inner bend hook 121 is pressed on the upper surface of the cover plate 2 after interference passing through the clamping hole 21 to prevent the clamping hole 21 from detaching from the clamping rod 12, so that the base plate 1 and the cover plate 2 form a snap connection.

[0025] The upper surface of the base plate 1 is also fixedly connected with a vertically arranged limit column 11. The core body 3 is composed of a plurality of steel sheets 30, and each steel sheet 30 is provided with a limit hole 31. In the present embodiment, there are two limit columns 11, which are respectively arranged on two symmetrical surfaces of the quadrilateral base plate 1, and each steel sheet 30 is also provided with two limit holes 31. The positions, shapes and sizes of the two limit holes 31 and the two limit columns 11 are matched one by one. The limit columns 11 and the limit holes 31 in the present embodiment are both cross-shaped. In addition, they can also be designed into a circle or other shapes. The core body 3 is fixed to the base plate 1 by inserting the limit columns 11 into the limit holes 31.

[0026] The upper surface of the cover plate 2 is also provided with a toggle assembly for pushing the inner hook 121 of the clamping rod 12 to reduce the diameter of the inner hook 121 and push it into the clamping hole 21, so that the cover plate 2 and the bottom plate 1 are unlocked from each other. In this embodiment, two groups of toggle assemblies are provided on the upper surface of the cover plate 2, and each group of toggle assemblies can push two adjacent clamping rods 12 synchronously. The two adjacent clamping rods 12 pushed by the same group of toggle assemblies are symmetrically arranged, that is, the inner hooks 121 of the two are arranged oppositely. The two groups of toggle assemblies are parallel to each other and symmetrically arranged on two opposite surfaces of the cover plate 2.

[0027] The structure of each group of toggle components is as follows: a slide rail 43 is fixedly arranged between two adjacent and inner-bend hooks 121 arranged opposite to each other and on the upper surface of the cover plate 2. Two fixed seats 41 are fixedly installed on the slide rail 43. A bidirectional screw rod 42 is inserted between the two fixed seats 41, and the slide rail 43 is located below the bidirectional screw rod 42 and the two are arranged parallel to each other, and the bidirectional screw rod 42 can rotate in the two fixed seats 41. The two ends of the bidirectional screw rod 42 pass through a fixed seat 41 to form a threaded section, and the thread directions of the two threaded sections at the two ends of the bidirectional screw rod 42 are opposite. The two threaded sections of the bidirectional screw rod 42 are also screwed with push blocks 44 respectively. Each push block 44 is located between the adjacent fixed seats 41 and the card rod 12. A card slot is formed at the bottom of the push block 44, and the card slot of the push block 44 is matched and installed on the slide rail 43, and the push block 44 can slide on the slide rail 43. Both ends of the bidirectional screw rod 42 pass through a push block 44 and are connected to a hand-tightening handle block 45 .

[0028] By rotating one end of the bidirectional screw rod 42, the two push blocks 44 on the bidirectional screw rod 42 can slide toward each other, and the two push blocks 44 can slide synchronously to the side of the clamp rod 12 close to it and push the inner hook 121 of the clamp rod 12, or the two push blocks 44 can slide synchronously to the side of the fixing seat 41 close to it. When the push blocks 44 push the inner hook 121 of the clamp rod 12, the transverse diameter of the inner hook 121 can be reduced, so that the clamping hole 21 of the cover plate 2 can pass through the inner hook 121, so that the cover plate 2 and the bottom plate 1 are separated from each other.

[0029] Furthermore, the two sets of bidirectional screw rods 42 of the toggle assembly are centrally symmetrically arranged, and pulleys 51 are respectively installed on the two bidirectional screw rods 42. The pulleys 51 on the two bidirectional screw rods 42 are symmetrically arranged, and a transmission belt 52 is commonly wound between the two pulleys 51.

[0030] Furthermore, a protective shell 6 for protecting the toggle assembly is installed on the top of the cover plate 2 .

[0031] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
