[0003] According to announcement number CN206639672U, a high-frequency anti-collision transformer is disclosed, including a transformer fixed shell, vibration damping baffle fixing screws, and terminal protection sleeves. The vibration damping baffle, together with vibration damping springs and their fixing brackets, forms a vibration damping and anti-collision mechanism, which is installed on both sides of the high-frequency transformer to reduce external impact forces. However, in the aforementioned document, the vibration damping baffle is installed on the left and right sides of the transformer, providing only lateral protection and failing to cope with impacts from the front and rear. These impact forces directly act on the transformer body, causing shell deformation and damage to internal components. Furthermore, the vibration damping baffle is fixed to the mounting holes with screws; removing the baffle during transformer maintenance requires significant time, delaying transformer fault handling and affecting power restoration time.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figures 1-6 The transformer is designed to withstand impacts. It includes a main body 24, with a support 1 at the lower end of the main body 24. The support 1 is equipped with a baffle 20 for impact protection. The baffle 20 has a hollow structure and can effectively buffer external impacts while facilitating heat dissipation of the main body 24. The support 1 consists of a base plate and four columns, with an anti-collision frame placed between two corresponding columns. The anti-collision frame consists of a sliding rod 10 and two fixing blocks 5.

[0026] Four lifting blocks 21 are slidably sleeved on the column, and a protective plate 23 for preventing the top of the main body 24 from impact is fixedly installed between the four lifting blocks 21. The protective plate 23 on the top protects the main body 24 and reduces the direct damage of the top impact force to the transformer body and internal core components. A spring 22 is welded between the lifting block 21 and the column. The spring 22 can provide a buffer for the protective plate 23 and reduce the impact force of the top impact on the main body 24.

[0027] The anti-collision frame is horizontally arranged, and the column has a storage groove corresponding to the fixing block 5. The protective plate 23 is horizontally arranged above the bracket 1. The spring 22 is vertically welded to the lower end of the lifting block 21 extending into the column. The protective plate 23 has a through hole for wiring. The through hole on the protective plate 23 facilitates the wiring connection at the top of the main body 24 without affecting its anti-collision function.

[0028] The column is equipped with a clamping structure for fixing block 5. The clamping structure allows for quick disassembly of the anti-collision frame without the need for complicated tools or long-term operation, thus shortening maintenance downtime and preventing damage to baffle 20 or transformer connection parts due to forced disassembly. It is suitable for emergency repair scenarios.

[0029] The clamp structure includes a positioning block 2 that is slidably sleeved inside the column and extends to the fixing block 5. A spring 2 3 is welded between the positioning block 2 and the column, which can push the positioning block 2 to extend into the positioning groove on the fixing block 5 to achieve clamp fixation of the fixing block 5. A lever 4 is fixedly installed on the positioning block 2. The bracket 1 is provided with a reinforcement structure to reinforce the lever 4. The lever 4 is reinforced by the movement of the reinforcement rod 9 against the lever 4 to prevent the positioning block 2 from loosening due to external force and affecting the clamping effect on the fixing block 5.

[0030] The reinforcement structure includes a clamp bracket 25 fixedly installed on the column, and a guide rod 6 is slidably sleeved on the clamp bracket 25. The guide rod 6 provides guidance for the movement of the reinforcement block 7, ensuring that the reinforcement rod 9 acts stably on the lever 4 and preventing the spring 8 from shifting under force. The reinforcement block 7 is fixedly installed on the guide rod 6. A spring 8 that cooperates with the guide rod 6 is welded between the reinforcement block 7 and the clamp bracket 25. The spring 8 can push the reinforcement block 7 to drive the reinforcement rod 9 to press against the lever 4. A lever block and the reinforcement rod 9 that move against the lever 4 are fixedly installed on the reinforcement block 7.

[0031] The positioning block 2 has a trapezoidal structure and is vertically positioned on both sides of the fixing block 5. The fixing block 5 has a positioning groove corresponding to the positioning block 2. The positioning groove cooperates with the positioning block 2 to achieve rapid positioning and stable clamping of the fixing block 5. The spring 2 3 is vertically welded.

[0032] The clamp bracket 25 is horizontally positioned on both sides of the fixing block 5, and the spring 8 is sleeved on the guide rod 6.

[0033] The anti-collision frame is equipped with a buffer structure to cushion the baffles 20. The buffer structure sets four buffer baffles 20 on the main body 24 to provide comprehensive protection for the main body 24. It can effectively absorb external impact energy and reduce the risk of equipment failure or scrapping caused by collision. By setting spring five 19 and spring four 13 to work together, the baffles 20 are double buffered. The coordinated work of spring five 19 and spring four 13 can disperse the impact force to different directions or time points, avoid single-point overload, and improve the overall anti-collision performance.

[0034] The buffer structure includes a U-shaped block 18 and two fixed plates 11 fixedly installed on the slide rod 10. A moving rod 17, two moving blocks 12 and a slider 14 are slidably sleeved on the slide rod 10. The moving rod 17 guides the buffer plate 16 to prevent the spring 19 from deviating when it is under force.

[0035] A spring 13 is welded between the movable block 12 and the fixed plate 11. The spring 13 absorbs the impact force of the movable block 12 and enhances the buffering effect through elastic reset, thus providing initial buffering and release of the impact force received by the baffle 20. A buffer plate 16, which is integrally connected to the baffle 20, is fixedly installed on the movable rod 17. A spring 19 is welded between the buffer plate 16 and the U-shaped block 18. The spring 19 absorbs the impact force transmitted by the buffer plate 16 through elastic deformation, thus providing secondary buffering and release of the impact force received by the baffle 20. A connecting rod 15 is pin-connected between the buffer plate 16 and the two sliders 14.

[0036] According to the instruction manual Figure 6 When the baffle 20 is subjected to an impact force, the baffle 20 drives the buffer plate 16 to move inward. The buffer plate 16 applies pressure to the spring 19, which absorbs the impact force. This initial absorption of the impact force on the baffle 20 is achieved. As the baffle 20 continues to be subjected to an impact force, the buffer plate 16, through the connecting rod 15 connected by the pin, causes the slider 14 to apply pressure to the moving block 12. This causes the slider 14 to apply pressure to the moving block 12, and the spring 13 absorbs the force on the baffle 20 again, achieving a double absorption effect of the impact force.

[0037] The slider 14 is located on both sides of the U-shaped block 18, the moving block 12 is located on both sides of the slider 14, the fixing plate 11 is located on both sides of the moving block 12, the spring 13 is horizontally sleeved on the slide rod 10, and the spring 19 is horizontally sleeved on the moving rod 17.

[0038] The functional principle of this utility model can be explained through the following operation methods:

[0039] When an external object hits the top of the transformer;

[0040] When the protective plate 23 is impacted, it moves downward. The protective plate 23 drives the lifting block 21 to move downward. The lifting block 21 applies pressure to the spring 22. The spring 22 deforms and absorbs the vertical impact, thus protecting the top of the transformer.

[0041] When an external object hits the side wall of the transformer;

[0042] When the baffle 20 is impacted, it moves inward. The baffle 20 drives the buffer plate 16 to move synchronously. The buffer plate 16 applies pressure to the spring 19. The spring 19 is under force. At the same time, the buffer plate 16 causes the connecting rod 15 connected by the pin to deflect around the pin seat. The connecting rod 15 drives the slider 14 to slide towards the moving block 12, thus providing initial buffering for the impact.

[0043] When the baffle 20 is impacted, it continues to move inward, causing the slider 14 to press on the moving block 12. When the moving block 12 slides on the slide bar 10, it presses on the spring 13 to buffer the impact force.

[0044] When the main body 24 needs repair;

[0045] When the lever on the reinforcing block 7 is moved, the lever causes the reinforcing block 7 to apply pressure to the spring 8. When the spring 8 is under force, the reinforcing block 7 and the reinforcing rod 9 are disengaged from the lever 4, and the reinforcing rod 9 is disconnected from the lever 4.

[0046] Move lever 4, lever 4 causes positioning block 2 to disengage from positioning groove on fixed block 5, spring 2 3 is stressed, positioning block 2 is disconnected from fixed block 5, fixed block 5 is removed, and the anti-collision frame is disassembled. The main body 24 is then repaired through the opening of baffle 20.

[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
