[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, the secondary coil, and the iron core (magnetic core). Its main functions include voltage transformation, current transformation, impedance transformation, isolation, and voltage stabilization.

[0003] The noise-reducing transformer disclosed in announcement number CN 216054233 U includes: a frame with a receiving slot; multiple magnetic cores housed in the receiving slot and stacked sequentially along the length of the receiving slot, sandwiched on opposite sides of the receiving slot; and coils wound around the frame and fitted with the multiple magnetic cores, wherein the multiple magnetic cores are stacked sequentially along the length of the receiving slot. This device does not have an elastic buffer structure, cannot perform graded buffering of the force applied to the transformer, and excessive pressure will affect the service life of the device. It also lacks shock-absorbing springs and dampers, and cannot provide shock absorption for the transformer. The noise generated during its operation cannot be effectively alleviated. Utility Model Content

[0004] The purpose of this invention is to provide a noise-reducing transformer to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A noise-reducing transformer includes a protective box. Sound-insulating cotton is fixedly installed on the inner wall of the protective box. A support base is fixedly installed on one side of the bottom of the protective box. A support rod is fixedly installed on the side of the support base. Buffer springs are fixedly installed on both sides of the support rod. One end of each buffer spring is fixedly connected to the support base. A movable block is movably installed on the outside of the support rod. The movable block is fixedly connected to the other end of each buffer spring. A control rod is movably installed at the top of the movable block. An mounting block is movably installed at the top of the control rod. A shock-absorbing mechanism is fixedly installed on both sides of the top of the support base. The shock-absorbing mechanism includes dampers and shock-absorbing springs. Several dampers are fixedly installed on both sides of the top of the support base, and shock-absorbing springs are fixedly installed around the top of each damper.

[0006] Preferably, a bearing plate is fixedly provided on the other side of the mounting block, and the bottom two sides of the bearing plate are fixedly connected to the damper. A transformer is fixedly provided on the top of the bearing plate. The bearing plate is designed to support the transformer. The transformer is a mature existing technology that can be applied to high-frequency current and low-frequency current.

[0007] Preferably, a cooling fan is fixedly installed on one side of the inner wall of the protective box, and a drive device is fixedly installed on the outer side of the protective box. One side of the drive device is fixedly connected to the cooling fan. The cooling fan is a mature existing technology. It is driven by a drive motor to provide electrical energy to make the cooling fan rotate at high speed to cool the transformer.

[0008] Preferably, a base plate is fixedly installed at the bottom of the protective box, and several fixing screws are fixedly installed on both sides of the top of the base plate. The device is stably fixed to the ground or other equipment by fixing screws 16.

[0009] Preferably, handles are fixedly installed on both sides of the outside of the protective box, and a vent is fixedly installed on one side of the outside of the protective box. The handles make it convenient for staff to lift the protective box, and the vent keeps the transformer inside in a constant temperature and ventilation state.

[0010] Preferably, a hinge is movably provided on one side of the top of the protective box, and a flip cover is movably provided on one side of the hinge. The flip cover can be opened and closed by the hinge to close the protective box.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This noise-reducing transformer is designed so that the operator first opens the flip-top plate using hinges, fixes the transformer onto the support plate, and secures the entire device to the ground or other equipment using fixing screws. The transformer presses downwards against the support plate, causing the control rods on both sides of the bottom of the support plate to extend outwards. Since the bottom of the control rods is movably connected to the top of the moving block, the extension of the control rods causes the moving block to move towards both ends of the support rod. Because buffer springs are installed on both sides of the support rod, with one end of the buffer spring connected to the moving block and the other end connected to the support base, the displacement of the moving block will compress the buffer springs, causing them to undergo elastic deformation, thus providing graded buffering of the applied force. Under the elastic buffering of the damper and the shock-absorbing spring, the transformer in operation can be damped, thereby reducing noise. The drive equipment is started through the existing wiring connection, driving the cooling fan to rotate and dissipate heat from the transformer.

[0012] 2. This noise-reducing transformer has an elastic buffer structure that can buffer the force applied to the transformer in stages, thereby reducing the pressure on the supporting device and extending its service life. The shock-absorbing spring and damper can dampen the transformer and effectively reduce the noise generated during operation. The cooling fan can keep the transformer at a constant temperature and prevent damage to internal parts due to overheating. Attached Figure Description

[0016] Please see Figures 1-5 As shown, this utility model provides a technical solution: A noise-reducing transformer includes a protective box 1. Sound insulation cotton 2 is fixedly installed on the inner wall of the protective box 1. A support base 3 is fixedly installed on one side of the bottom of the protective box 1. A support rod 4 is fixedly installed on the side of the support base 3. Buffer springs 5 ​​are fixedly installed on both sides of the support rod 4. One end of the buffer spring 5 is fixedly connected to the support base 3. A movable block 6 is movably installed on the outside of the support rod 4. The movable block 6 is fixedly connected to the other end of the buffer spring 5. A control rod 7 is movably installed at the top of the movable block 6. An mounting block 8 is movably installed at the top of the control rod 7. A shock-absorbing buffer mechanism is fixedly installed on both sides of the top of the support base 3. The shock-absorbing buffer mechanism includes dampers 9 and shock-absorbing springs 10. Several dampers 9 are fixedly installed on both sides of the top of the support base 3. Shock-absorbing springs 10 are fixedly installed around the top of the dampers 9.

[0017] In this embodiment, preferably, a bearing plate 11 is fixedly provided on the other side of the mounting block 8. The bottom two sides of the bearing plate 11 are fixedly connected to the damper 9. A transformer 12 is fixedly provided on the top of the bearing plate 11. The bearing plate is set to support the transformer. The transformer is an existing mature technology that can be applied to high-frequency current and low-frequency current.

[0018] In this embodiment, preferably, a cooling fan 13 is fixedly installed on one side of the inner wall of the protective box 1, and a drive device 14 is fixedly installed on the outer side of the protective box 1. One side of the drive device 14 is fixedly connected to the cooling fan 13. The cooling fan is a mature existing technology. It is driven by a drive motor to provide power so that the cooling fan can rotate at high speed to cool the transformer.

[0019] In this embodiment, preferably, a base plate 15 is fixedly installed at the bottom of the protective box 1, and a number of fixing screws 16 are fixedly installed on both sides of the top of the base plate 15. The device is stably fixed to the ground or other equipment by fixing screws 16.

[0020] In this embodiment, preferably, handles 17 are fixedly provided on both sides of the outside of the protective box 1, and a vent 18 is fixedly provided on one side of the outside of the protective box 1. The handles make it convenient for staff to lift the protective box, and the vent keeps the transformer inside in a constant temperature and ventilation state.

[0021] In this embodiment, preferably, a hinge 19 is movably provided on one side of the top of the protective box 1, and a flip cover 20 is movably provided on one side of the hinge 19. The flip cover 20 can be opened and closed by the hinge to close the protective box.

[0022] In this embodiment, a noise-reducing transformer is used. The operator first opens the flip-top 20 using hinge 19 and fixes the transformer 12 onto the support plate 11. The entire device is then securely fixed to the ground or other equipment using fixing screws 16. The transformer 12 presses downwards against the support plate 11, causing the control rods 7 on both sides of the bottom of the support plate 11 to extend outwards. Since the bottom of the control rods 7 is movably connected to the top of the moving block 6, the extension of the control rods 7 causes the moving block 6 to move towards both ends of the support rod 4. Because buffer springs 5 ​​are provided on both sides of the support rod 4, with one end of the buffer spring 5 connected to the moving block 6 and the other end connected to the support base 3, the displacement of the moving block 6 compresses the buffer springs 5, causing them to become elastic. The deformation is used to buffer the applied force in stages. Under the elastic buffering of the damper 9 and the shock-absorbing spring 10, the transformer 12 can be damped and buffered during operation, thereby reducing noise. The drive device 14 is started through the existing wiring connection, which drives the cooling fan 13 to rotate and dissipate heat from the transformer 12. The device has an elastic buffer structure, which can buffer the force applied to the transformer 12 in stages, thereby reducing the pressure on the support device and extending its service life. The shock-absorbing spring 10, together with the damper 9, can dampen the transformer 12 and effectively reduce the noise generated during its operation. The setting of the cooling fan 13 can keep the transformer 12 at a constant temperature and prevent damage to internal parts due to overheating.
