Description

Technical Field

[0001] This utility model relates to the field of dry-type transformer technology, specifically to a snap-on pull plate structure for a dry-type transformer. Background Technology

[0002] Transformers are fundamental equipment for power transmission and distribution, widely used in industry, agriculture, transportation, urban communities, and other fields. A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, secondary coil, and iron core. Its main functions include voltage transformation, current transformation, impedance transformation, isolation, and voltage stabilization. Dry-type transformers are a type of transformer and are widely used in local lighting, high-rise buildings, airports, docks, CNC machinery equipment, and other places. Simply put, a dry-type transformer is a transformer whose iron core and windings are not immersed in insulating oil.

[0003] In the assembly process of dry-type transformer cores, traditional methods usually require pre-processing of sheet metal parts such as punching and bending, followed by fixing the components together with long bolts. This assembly method is not only cumbersome, requiring multiple positioning and tightening, but also requires high precision in the bolt connections, and even slight deviations can lead to assembly difficulties. In addition, the tightening process of long bolts is time-consuming and requires repeated adjustments, resulting in a significant reduction in overall assembly efficiency. This makes it difficult to meet the demands of modern industrial production for efficient and convenient assembly, and brings many inconveniences to actual use. Utility Model Content

[0004] The purpose of this utility model is to provide a snap-on pull plate structure for dry-type transformers in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution: a dry-type transformer snap-on pull plate structure, comprising: a telescopic pull rod assembly, an upper clamp, and a lower clamp; two mounting plates, each mounted on one end of the telescopic pull rod assembly; and two rotating clamping plates, each rotatably mounted on one side of the two mounting plates. The ends of both the upper and lower clamps are provided with insertion ports and slots. When a rotating clamping plate passes through an insertion port, it can rotate to engage one end with a slot.

[0006] Furthermore, the telescopic rod assembly includes a threaded rod and a threaded cylinder. One end of the threaded rod is rotatably inserted into the mounting plate, and one end of the threaded cylinder is rotatably inserted into another mounting plate. The threaded rod and the threaded cylinder are threadedly connected.

[0007] Furthermore, a cylinder is fixedly inserted into one end of the mounting plate, a short rod is slidably inserted into the cylinder, a return spring is fixedly installed between one end of the short rod and the inner wall of the cylinder, and one end of the rotating plate is rotatably connected to the other end of the short rod.

[0008] Furthermore, a handle is fixedly installed at the other end of the rotating plate, and an anti-slip pad is fixedly sleeved on the outer surface of the handle.

[0009] Furthermore, a positioning block is fixedly installed at one end of the rotating clamping plate, and positioning grooves are constructed in the slots on the mounting plate, the upper clamping member, and the lower clamping member, and the positioning block is adapted to the positioning groove.

[0010] Furthermore, a slider is fixedly installed on the outer periphery of the short rod, and a groove is constructed on the inner wall of the cylinder, in which the slider is slidably installed.

[0011] Furthermore, a protective cover is provided on the rotating clamping plate, and a magnet is provided on the protective cover. The magnet is magnetically connected to the side of the upper clamping member or the lower clamping member.

[0012] The beneficial effects of this utility model are as follows:

[0013] This invention utilizes a rotating clamping plate to engage its end with the slots at the ends of the upper and lower clamping parts, thereby retracting the telescopic pull rod assembly to form a snap-fit ​​connection. This allows for the rapid fixing of the upper and lower clamping parts, facilitating the assembly of the dry-type transformer core. This structure replaces traditional bolt connections with snap-fit ​​connections, eliminating pre-processing steps such as punching and bending, reducing reliance on hole position accuracy. Furthermore, the telescopic adjustment of the pull rod assembly and the rotational engagement of the clamping plate simplify the assembly process, improve assembly efficiency, and meet the demands of modern industrial production for efficient and convenient assembly.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0020] like Figure 1-4 As shown, an embodiment of the present invention provides a snap-on pull plate structure for a dry-type transformer, comprising: a telescopic pull rod assembly 1, an upper clamp 2, and a lower clamp 3;

[0021] Mounting plates 4, there are two of them, and the two mounting plates 4 are respectively installed at both ends of the telescopic tie rod assembly 1;

[0022] There are two rotating clamping plates 5, which are respectively rotatably installed on one side of the two mounting plates 4. The ends of the upper clamping member 2 and the lower clamping member 3 are both constructed with insertion ports and slots. When the rotating clamping plate 5 passes through the insertion port, it can be rotated so that one end of it engages with the slot.

[0023] During the assembly of the dry-type transformer core, the upper clamp 2 and lower clamp 3 are placed and installed in their designated positions. The telescopic pull rod assembly 1 is placed on the same plane as the corresponding insertion slots. The two ends of the telescopic pull rod assembly 1 are fixed with mounting plates 4. Rotating clamping plates 5 are rotatably installed on the mounting plates 4. When the insertion slots of the upper clamp 2 and lower clamp 3 are aligned with the rotating clamping plates 5, the telescopic pull rod assembly 1 extends to allow the two rotating clamping plates 5 to pass through the insertion slots. Then, by rotating the rotating clamping plates 5, their ends are engaged in the slots at the ends of the upper clamp 2 and lower clamp 3, and the telescopic pull rod assembly 1 is retracted to form a snap-fit ​​connection. This quickly fixes the upper clamp 2 and lower clamp 3, realizing the assembly of the dry-type transformer core. This structure replaces the traditional bolt connection with a snap-fit ​​connection, avoiding pre-processing steps such as punching and bending, reducing the dependence on hole position accuracy. At the same time, the telescopic adjustment of the telescopic pull rod assembly 1 and the rotation of the rotating clamping plates 5 simplify the assembly steps, improve assembly efficiency, and meet the needs of modern industrial production for efficient and convenient assembly.

[0024] like Figure 2As shown, in some embodiments, the telescopic rod assembly 1 includes a threaded rod 11 and a threaded cylinder 12. One end of the threaded rod 11 is rotatably inserted into the mounting plate 4, and one end of the threaded cylinder 12 is rotatably inserted into another mounting plate 4. The threaded rod 11 and the threaded cylinder 12 are threadedly connected.

[0025] The threaded rod 11 of the telescopic tie rod assembly 1 is threadedly connected to the threaded cylinder 12. One end of the threaded rod 11 is rotatably inserted into a mounting plate 4, and one end of the threaded cylinder 12 is rotatably inserted into another mounting plate 4. When assembly is required, the threaded cylinder 12 is rotated to move axially along the threaded rod 11, thereby adjusting the overall length of the telescopic tie rod assembly 1. The rotating clamping plate 5 is aligned with the insertion ports at the ends of the upper clamping member 2 and the lower clamping member 3 and passes through. Then, the rotating clamping plate 5 is rotated so that its end is engaged in the slot, forming a snap-fit ​​connection, thereby quickly fixing the upper clamping member 2 and the lower clamping member 3 and realizing the assembly of the dry-type transformer core. This structure achieves length adjustment through the threaded engagement of the threaded rod 11 and the threaded cylinder 12, avoiding the dependence on hole position accuracy of traditional bolt connections.

[0026] like Figure 2 As shown, in some embodiments, a cylinder 6 is fixedly inserted into one end of the mounting plate 4, a short rod 7 is slidably inserted into the cylinder 6, a return spring 8 is fixedly installed between one end of the short rod 7 and the inner wall of the cylinder 6, and one end of the rotating plate 5 is rotatably connected to the other end of the short rod 7.

[0027] The return spring 8 ensures that the rotating plate 5 is always tightly attached to the slot, preventing loosening and improving assembly stability. Under the action of the return spring 8, the rotating plate 5 is firmly locked in the slot, and when the locking is released, it is not necessary to adjust the entire telescopic rod assembly 1. Simply pull the rotating rod 5 to move one end out of the slot to release the locking, which is simple and convenient to operate.

[0028] like Figure 2 As shown, in some embodiments, a handle 9 is fixedly installed at the other end of the rotating plate 5, and an anti-slip pad 10 is fixedly sleeved on the outer surface of the handle 9.

[0029] The handle 9 and the anti-slip pad 10 facilitate pulling and rotating the card plate 5, allowing one end to move out of the slot, making it easier for people to operate.

[0030] like Figure 3 As shown, in some embodiments, a positioning block 13 is fixedly installed at one end of the rotating clamping plate 5, and positioning grooves are constructed in the slots on the mounting plate 4, the upper clamping member 2, and the lower clamping member 3, and the positioning block 13 is adapted to the positioning groove.

[0031] The positioning block 13 is inserted into the slot on the upper clamp 2 or the lower clamp 3, which further consolidates the engagement between the rotating plate 5 and the slot. When the positioning block 13 is inserted into the positioning groove on the mounting plate 4, it is easy to disassemble. The rotating plate 5 will not rotate arbitrarily, making it easy for the rotating plate 5 to pass through the insertion port and move out.

[0032] like Figure 3 As shown, in some embodiments, a slider 14 is fixedly installed on the outer periphery of the short rod 7, and a groove is constructed on the inner wall of the cylinder 6, in which the slider 14 is slidably installed.

[0033] The design of the groove and slider 14 facilitates the movement of the short rod 7 along the length of the inner wall of the cylinder 6 without rotation, thus facilitating the use of the return spring 8 and preventing it from rotating or twisting, which would affect its use.

[0034] like Figure 2 As shown, in some embodiments, the rotating clamping plate 5 is provided with a protective cover 15, and the protective cover 15 is provided with a magnet 16, which is magnetically connected to the side of the upper clamping member 2 or the lower clamping member 3.

[0035] The protective cover 15 is used to cover the rotating card plate 5 and the socket to prevent them from being exposed, damaged by external objects, or operated arbitrarily.

[0036] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
