Abstract
Description
Technical Field
[0001] This utility model belongs to the field of winding frame technology, and in particular relates to a combined transformer winding frame. Background Technology
[0002] Transformers are frequently used electronic components in various electrical devices to adjust different voltages, ensuring the voltage reaches the range suitable for the electrical equipment, thus enabling the equipment to operate. The transformer winding frame is one of the important components of a transformer, and its structure is typically adjusted according to changes in its required function and application.
[0003] Most transformer winding frames on the market are designed for separate installation. This can be troublesome and inconvenient when two winding frames need to be combined and fixed. Utility Model Content
[0004] To address the problems existing in the prior art, this utility model provides a combined transformer winding frame. Two fixed cylinders inside the protective box are inserted into the central circular hole of the winding frame body. Rotating the rotating ring drives the screw to rotate. The screw is threadedly connected to the inside of the fixed cylinder, thus moving within the fixed cylinder and simultaneously moving the conical column. When the conical column moves, it contacts the protrusion, causing it to compress. The protrusion then expands outwards and contacts the central circular hole of the winding frame body for expansion and fixation. The anti-slip texture increases friction and strengthens the fixing effect, making it easier to assemble two winding frame bodies.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a combined transformer winding frame, comprising a winding frame body and a protective box, wherein two fixed cylinders are fixedly connected inside the protective box, and multiple protrusions are provided at the bottom end of the fixed cylinders. A screw is threadedly connected inside the fixed cylinders, a conical column is fixedly connected to one end of the screw, and a swivel is fixedly connected to the other end of the screw. The screw is threadedly connected to the inside of the fixed cylinders, and the surface of the protrusions is provided with anti-slip texture.
[0006] Furthermore, the fixed cylinder has multiple vertical grooves at one end corresponding to the protrusion position, and the vertical grooves are located between two adjacent protrusions.
[0007] Furthermore, one end of the fixing cylinder is fixed through and extends above the protective box, and the surface of the conical cylinder is in contact with the protrusion.
[0008] Compared with the prior art, the beneficial effects of this utility model are:
[0009] By inserting the two fixed cylinders inside the protective box into the central circular hole of the winding frame body, and then rotating the rotating ring, the screw is driven to rotate. The screw is connected to the thread inside the fixed cylinder, so it moves inside the fixed cylinder, which in turn drives the conical column to move. When the conical column moves, it contacts the protrusion and squeezes the protrusion. At this time, the protrusion expands outward and contacts the inside of the central circular hole of the winding frame body for expansion and fixation. With the anti-slip texture, the friction is increased and the fixing effect is strengthened, making it easier to splice the two winding frame bodies. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0015] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Example
[0016] See appendix Figure 1-3As shown, a combined transformer winding frame includes a winding frame body 1 and a protective box 2. Two fixed cylinders 3 are fixedly connected inside the protective box 2. Multiple protrusions 6 are provided at the bottom end of the fixed cylinders 3. A screw 4 is threadedly connected inside the fixed cylinders 3. A conical column 5 is fixedly connected to one end of the screw 4, and a swivel ring 8 is fixedly connected to the other end of the screw 4. The screw 4 is threadedly connected to the inside of the fixed cylinders 3. The surface of the protrusions 6 is provided with anti-slip textures 7.
[0017] The fixed cylinder 3 has multiple vertical grooves at one end corresponding to the position of the protrusion 6, and the vertical grooves are located between two adjacent protrusions 6.
[0018] One end of the fixed cylinder 3 is fixed through and extends above the protective box 2, and the surface of the conical column 5 is in contact with the protrusion 6.
[0019] Working principle: When splicing and fixing the two winding frame bodies 1, the two fixing cylinders 3 inside the protective box 2 are inserted into the central circular hole of the winding frame body 1. Then, the rotating ring 8 is rotated, which drives the screw 4 to rotate. The screw 4 is threadedly connected to the inside of the fixing cylinder 3, so it moves inside the fixing cylinder 3. At the same time, it drives the conical column 5 to move. When the conical column 5 moves, it contacts the protrusion 6 and squeezes the protrusion 6. At this time, the protrusion 6 expands outward and contacts the inside of the central circular hole of the winding frame body 1 for expansion and fixing. With the anti-slip texture 7, the friction is increased and the fixing effect is strengthened, making it easier to splice the two winding frame bodies 1. With the setting of the protective box 2, the two winding frame bodies 1 also play a protective role.

Therefore, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this utility model, and no reference numerals in the claims should be construed as limiting the scope of the claims.
[0021] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
