Description

Technical Field

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

[0002] A transformer is a device used for converting electric energy. It can adjust the voltage in the power grid to achieve power transmission and distribution. It can convert AC power of different voltage and current into AC power of another voltage and current. Since the transformer will generate vibration and noise when working, this will affect its surrounding environment and long-term stability. Therefore, in order to reduce the vibration and noise of the transformer, a shock-absorbing device is required. A shock-absorbing transformer is a transformer equipped with a shock-absorbing device. The shock-absorbing transformer has little impact on the environment during use, and because it is equipped with a shock-absorbing device, it is also convenient for transportation.

[0003] For this purpose, the utility model patent with the publication number CN219800594U discloses a shock-absorbing transformer, including a transformer body and a shock-absorbing base, wherein the shock-absorbing base includes a fixed bottom plate, a base, a main shock-absorbing component and a secondary shock-absorbing component, wherein the transformer body is fixed on the fixed bottom plate, the fixed bottom plate is movably arranged in the shock-absorbing groove of the base, the main shock-absorbing component is arranged at equal intervals in the middle between the fixed bottom plate and the base, and the secondary shock-absorbing component is arranged around the periphery of the main shock-absorbing component. The utility model can buffer the vibration generated during transportation or installation and use by arranging a shock-absorbing base with a buffering and shock-absorbing function at the bottom of the transformer body, thereby avoiding damage to the transformer due to vibration and prolonging the service life of the transformer.

[0004] However, the transformer body of the patent is fixed on a fixed base plate, and the transformer body is usually heavy. It is inconvenient to repair and inspect the shock absorbing device without removing the transformer body, and the patent is not convenient to fix during transportation and installation. Utility Model Content

[0005] The purpose of the utility model is to provide a vibration-damping transformer to address the deficiencies of the above-mentioned prior art. The transformer has a good fixing effect and is convenient for removing the transformer body and fixing it during transportation or installation.

[0006] The technical solution adopted by the utility model is a shock-absorbing transformer, comprising a transformer body, a shock-absorbing box is arranged below the transformer body, fixing devices are arranged in four walls of the shock-absorbing box, a support plate is arranged in the shock-absorbing box, the top of the support plate is contacted and connected with the transformer body, a shock-absorbing device is arranged at the bottom of the support plate, and the support plate is slidably connected with the shock-absorbing box through the shock-absorbing device.

[0007] Preferably, the fixing device comprises a handle, one end of which is fixedly connected to a cylinder, a surface of the cylinder is provided with a thread integrally formed with the cylinder, and an end of the cylinder away from the handle passes through a wall of the shock absorbing box and is rotatably connected to a fixing plate.

[0008] Preferably, mounting plates are fixedly mounted on both sides of the shock-absorbing box, and a mounting hole is opened at the center of the mounting plate.

[0009] Preferably, the shock absorbing device includes a support column, both ends of which are fixedly connected to the inner wall of the shock absorbing box, a spring is sleeved on the surface of the support column, one end of the spring is in contact with the inner wall of the shock absorbing box, and the other end is fixedly connected to a slider, the slider is slidably installed on the surface of the support column, the top of the slider is rotatably connected to one end of the connecting column, the other end of the connecting column is rotatably connected to a support block, and the top of the support block is fixedly connected to the support plate.

[0011] Preferably, a buffer pad is fixedly installed at the contact point between the support plate and the transformer body.

[0012] The utility model is simple and convenient to use. It only requires placing the transformer body on the surface of the support plate, and then holding the handle and rotating it to fix the transformer body. When vibration occurs, the transformer body will push the support block downward, and the support block will transmit the thrust to the spring through the connecting block and the slider to achieve buffering, thereby reducing the shaking of the transformer body.

[0013] Compared with the prior art, the beneficial effect of the utility model is that the transformer body is fixed by a fixing device, and when the shock absorber box needs to be repaired and inspected, the transformer can be conveniently removed to carry out maintenance and inspection of the shock absorber box.
