Description

Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to a transformer. Background Art

[0002] With the development and progress of society, power systems are playing an increasingly important role in modern society. Transformers, as a crucial component of power transmission, convert AC voltage (current) of one value into voltage (current) of another value at the same frequency. Due to varying operating environments and usage requirements, transformer design demands are becoming increasingly stringent. Especially for transformers requiring regular maintenance or repositioning, achieving convenient and secure movement and fixation has become a key focus in the industry.

[0003] Traditional transformers are typically fixed to specific locations. Once installed, they are difficult to relocate, significantly hindering subsequent maintenance. Furthermore, in specialized applications, such as temporary power needs or changes in construction sites, frequent transformer removal and installation is not only time-consuming and labor-intensive, but can also damage the equipment. Therefore, designing a transformer that ensures both stable operation and easy mobility is crucial.

[0004] While some existing solutions have addressed this issue, such as adding casters to increase transformer mobility, these approaches often suffer from complex structures, high costs, and insufficient stability. Especially when the casters are not in use, they require repeated removal and installation. Furthermore, the protruding casters interfere with the mounting bracket's connection to other mounting surfaces, compromising the stability of the entire device.

[0005] In view of this, the present application aims to provide a transformer with a new structure, which can maintain good stability while having simple and quick mobility, and can flexibly switch between the installed state and the mobile state according to actual needs, thereby effectively solving the defects existing in the existing technology. Utility Model Content

[0006] In view of the deficiencies in the background technology, the utility model provides a transformer.

[0007] The technical solution adopted by the utility model is: a transformer, comprising a transformer housing, a mounting base block is provided at the bottom of the transformer housing, a mounting bracket is fixed at the bottom of the mounting base block, a roller assembly is provided at the bottom of the mounting bracket, and a roller groove is provided at the bottom of the mounting bracket;

[0008] The roller assembly includes an "N"-shaped frame, a roller connected to the "N"-shaped frame through a rotating shaft, and a connecting piece for connecting the "N"-shaped frame to the mounting bracket. There are three connecting pieces, which are respectively arranged on the upper side, left side and right side of the "N"-shaped frame. The connecting piece includes a screw with a screw head and a nut threadedly connected to the screw. The "N"-shaped frame and the screw of the connecting piece are rotatably connected.

[0009] Furthermore, a plurality of positioning holes are arranged in a circumferential array on the roller, and a positioning screw is threadedly connected to the side wall of the "n"-shaped frame.

[0010] Furthermore, the mounting bracket and the mounting base block are connected by bolts.

[0011] Furthermore, a plurality of heat dissipation fins are provided at equal intervals on the outer wall of the transformer housing.

[0012] Furthermore, mounting plates are integrally formed on both sides of the mounting bracket, and a plurality of mounting holes are arranged at equal intervals along the length direction of the mounting plates.

[0013] Furthermore, the rotating shaft and the roller are rotationally connected via a bearing.

[0014] The beneficial effects of the utility model are:

[0015] 1. Convenient Mobility: By installing a mounting base block at the bottom of the transformer housing and attaching the mounting bracket and roller assembly to it, the transformer can be easily moved when needed. Especially in the case of temporary power supply or changes in the construction site, the position can be adjusted without disassembling the entire device, greatly improving work efficiency.

[0016] 2. Simple Switching Mechanism: The roller assembly utilizes a unique "n"-shaped frame design with a rotatable connector (screw and nut). This allows the user to retract the roller assembly into the roller slot simply by loosening the upper connector. This design not only simplifies the transition from mobile to fixed position, but also makes operation simple and quick, allowing even non-professionals to quickly complete the state switch.

[0017] 3. Enhanced stability: When the roller function is not needed, the roller can be stored in the roller groove, solving the safety hazards and instability problems caused by the exposure of traditional casters.

[0018] 4. Optimized space utilization: Since the rollers can be hidden, the space occupied is reduced without affecting normal operation, which is particularly suitable for applications with limited space. At the same time, this compact design also helps to improve transportation efficiency and reduce logistics costs.

[0019] In addition to the above-described purposes, features and advantages, the present invention has other purposes, features and advantages. The present invention will be further described in detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), such directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0025] The utility model provides a transformer.

[0026] In this embodiment, referring to Figure 1-2 The transformer comprises a transformer housing, wherein a mounting base block 2 is provided at the bottom of the transformer housing 1, a mounting bracket 3 is fixed to the bottom of the mounting base block 2, a roller assembly is provided at the bottom of the mounting bracket 3, and a roller groove 4 is provided at the bottom of the mounting bracket;

[0027] The roller assembly includes an "N"-shaped frame 5, a roller 7 connected to the "N"-shaped frame through a rotating shaft 6, and a connecting piece for connecting the "N"-shaped frame to the mounting bracket. There are three connecting pieces, which are respectively arranged on the upper side, left side and right side of the "N"-shaped frame. The connecting piece includes a screw rod 8 with a screw head and a nut 9 threadedly connected to the screw rod 8. The "N"-shaped frame and the screw rod of the connecting piece are rotatably connected.

[0028] In this technical solution, the transformer's mobility is achieved by installing a mounting base block at the bottom of the transformer housing, along with a mounting bracket and roller assembly. When the transformer needs to be moved, the rollers can be easily pushed and pulled; and when the transformer needs to be positioned, the roller assembly can be retracted into the roller slot for stable fixation.

[0029] The "n"-shaped frame of the roller assembly connects to the mounting bracket via three connectors (top, left, and right), forming a stable triangular support structure. This design not only enhances the overall structural stability but also allows the user to easily deploy and retract the rollers.

[0030] When storage is needed, you only need to remove the upper connecting piece, loosen the connecting pieces on both sides, and then rotate the roller assembly into the roller groove. After storage, lock the connecting pieces on both sides to complete the storage of the roller assembly.

[0031] Specifically, a plurality of positioning holes 10 are arranged in a circumferential array on the roller 7, and a positioning screw 11 is threadedly connected to the side wall of the "n"-shaped frame.

[0032] In this embodiment, the positioning holes on the rollers, combined with the positioning screws on the side walls of the "n"-shaped frame, lock the rollers into position when they are rotated to the desired position, preventing them from accidentally rolling when they are not required to move. This improves the safety of the transformer when it is stationary and also facilitates the adjustment and control of the rollers' direction.

[0033] Specifically, the mounting bracket and the mounting base block are connected by bolts.

[0034] In this embodiment, the mounting bracket and the mounting base are connected by bolts, which allows the entire roller assembly to be quickly disassembled or replaced, facilitating routine maintenance and repair work. In addition, this connection method also ensures a tight connection between the two, ensuring the integrity and reliability of the structure.

[0035] Specifically, a plurality of heat dissipation fins 12 are provided at equal intervals on the outer wall of the transformer housing.

[0036] In this embodiment, the heat dissipation fins provided on the outer wall of the transformer housing increase the housing surface area, helping to improve the efficiency of heat dissipation, thereby maintaining the internal temperature of the transformer within a safe operating range. This is of great significance for extending the life of the equipment and improving operating efficiency.

[0037] Specifically, mounting plates 13 are integrally formed on both sides of the mounting bracket, and a plurality of mounting holes 14 are evenly spaced along the length direction of the mounting plates 13 .

[0038] In this embodiment, the mounting hole 14 is used for mounting and fixing the transformer.

[0039] Specifically, the rotating shaft and the roller are rotatably connected via a bearing.

[0040] In this embodiment, the bearing connection between the rotating shaft and the roller reduces the friction between the two, so that the roller can rotate more smoothly.

[0041] Technical personnel please note: Although the utility model has been described according to the above specific implementation methods, the concept of the utility model is not limited to this utility model. Any modification using the concept of the utility model will be included in the scope of protection of this patent right.
