Description

Technical Field

[0001] The present invention relates to the technical field of transformers, and particularly to a transformer with a shock absorption function. Background Art

[0002] A large amount of vibration is generated when the transformer is in use or being transported. A large number of precision components are installed inside the transformer. These components will become loose when encountering relatively large vibrations, which will affect the use efficiency. Currently, existing transformers usually use elastic shock absorption or magnetic shock absorption methods for shock absorption. After shock absorption, the vibration amplitude of the transformer decreases, but it will still shake due to the reaction force, resulting in increased wear of the transformer and reduced service life.

[0003] The patent with the patent number CN202022223823.4 discloses a transformer housing with a shock absorption function. The first shock absorption mechanism of this patent can play a shock absorption role when the transformer shakes in the front, back, left, and right directions. Compared with the transformer housing that only has the shock absorption function in the up and down directions in the prior art, the shock absorption effect is better and the service life is longer. The second shock absorption mechanism can play an auxiliary shock absorption role to further improve the shock absorption effect, thereby reducing the noise generated during the operation of the transformer and avoiding damage caused by the shaking of the vehicle during the transportation of the transformer. Although this patent solves the above problems, there are still problems such as a slow shock absorption process, inability to quickly stop the movement of the transformer, and serious wear of the transformer. Therefore, it is very necessary to design a transformer with a shock absorption function that can quickly stop the movement of the transformer, reduce the wear of the transformer, and play a better protective role. Summary of the Invention

[0004] The purpose of the present invention is to provide a transformer with a shock absorption function to solve the problems raised in the above background art.

[0005] To solve the above technical problems, the present invention provides the following technical solution: A transformer with a shock-absorbing function, comprising a transformer body, a protective inner shell is fixedly connected to the outer surface of the transformer body, sliding seats are fixedly connected to the upper and lower sides of the protective inner shell, a horizontal sliding rod is slidably connected to the inner surface of the sliding seat, protective outer shells are fixedly connected to both ends of the horizontal sliding rod, vertical sliding rods are fixedly connected to the upper and lower sides of the inner wall of the protective outer shell, a sliding shaft is slidably connected to the outer surface of the vertical sliding rod, an X-shaped toggle link is hinged to the outside of the sliding shaft, energy dissipation devices are arranged on both sides of the transformer body for reducing the excess energy during vibration and extending the service life of the shock-absorbing structure, support devices are arranged on both sides of the protective outer shell for preventing the transformer from tipping over when the vibration amplitude is too large, the side of the X-shaped toggle link away from the sliding shaft is hinged to the inner side of the protection, springs are arranged between both ends of the sliding seat and both sides of the inner wall of the protective outer shell, two sliding shafts are slidably connected to the upper and lower sides of the vertical sliding rod, and a tension spring is arranged between the two sliding shafts. When the protective outer shell and the transformer body are affected by external factors and vibrate, the vibration force is first transmitted to the protective inner shell, and then conducted from the protective inner shell to the sliding seat. The vibration force causes the sliding seat to slide left and right on the horizontal sliding rod and compress the spring, causing the X-shaped toggle link to close. During the closing process of the X-shaped toggle link, the upper and lower two sliding shafts are driven to slide towards the upper and lower ends of the vertical sliding rod, causing the two sliding shafts to move away from each other. At this time, the two sliding shafts pull the tension spring, thereby forming a tension on both sides of the protective inner shell.

[0006] According to the above technical solution, the energy dissipation device includes a push shaft, a lead screw, and a connecting block. The push shaft is fixedly connected to both sides of the inner protective frame. The lead screw is movably connected to the inner surface of the push shaft. The connecting block is fixedly connected to the outer surface of the push shaft. The energy dissipation device further includes a connecting piece, an expansion rod, a friction arc plate, a friction sleeve, and a limiting plate. The connecting piece is hinged to both sides of the connecting block. The expansion rod is hinged to one end of the connecting piece away from the connecting block. The friction arc plate is fixedly connected to the side of the expansion rod away from the push shaft. The friction sleeve is fixedly connected to both sides of the inner wall of the protective shell. The limiting plate is fixedly connected to both sides of the inner wall of the protective sleeve. The lead screw rotates through both sides of the protective sleeve. The lead screw is rotatably connected to the inner surface of the limiting plate. The limiting plate is fixedly connected to the inner wall of the friction sleeve. A first chute is provided on the inner side of the limiting plate, and one end of the expansion rod away from the push shaft is slidably connected to the inner surface of the first chute. The lead screw is non-self-locking. When the transformer body and the inner protective shell shake left and right, it drives the push shaft to move left and right. When the push shaft moves left and right, it frictions the lead screw. When the push shaft moves and contacts the limiting plate, the hinged end of the connecting piece and the connecting block moves along with the push shaft. Also, because one end of the expansion rod abuts against the inner wall of the protective shell, when the hinged end of the connecting piece and the connecting block approaches the inner wall of the protective shell, the other end will push the expansion rod outward, causing the expansion rod to slide and expand in the first chute. During the expansion process of the expansion rod, it drives the friction arc plate to expand. Finally, the friction arc plate abuts against the inner wall of the friction sleeve and becomes a tensioned state. At this time, when the push shaft moves in the opposite direction, a frictional force will be generated between the friction arc plate and the friction sleeve.

[0007] According to the above technical solution, the support device includes a support block, a support plate, and a hook. The support block is fixedly connected to both sides of the protective shell. The support plate is hinged to one end of the support block away from the protective shell. The hook is fixedly connected to one end of the lead screw passing through the protective sleeve. The support device further includes a hanging plate, a telescopic rod, and a slider. The hanging plate is fixedly connected to the side of the support plate close to the hook. The telescopic rod is hinged to both sides of the protective shell. The slider is hinged to the bottom end of the telescopic rod. A second chute is provided on the inner side of the support plate, and the slider is slidably connected to the inner surface of the second chute. A torsion spring is provided at the hinge point between the support plate and the support block. The telescopic rod is self-locking. When the push shaft moves left and right on the surface of the lead screw, it drives the lead screw to rotate slightly. When the force of the vibration is too large and causes the push shaft to move too far, the rotation amplitude of the lead screw becomes relatively larger. At this time, the lead screw can drive the hook to rotate and disengage from the hanging plate. When the hanging plate loses the locking of the hook, the torsion spring between the support plate and the support block drives the support plate to rotate and reset to be flush with the ground. During the rotation process of the support plate, due to gravity, it pulls the telescopic rod to extend. When the telescopic rod reaches the limit of extension, the self-locking mechanism inside it locks the two end rods.

[0008] Compared with the prior art, the beneficial effects achieved by the present invention are: The present invention is provided with a vertical sliding rod, a sliding shaft, and an X-shaped toggle connecting rod. The sliding seat slides left and right on the horizontal sliding rod and squeezes the spring. The spring absorbs the shock to reduce the vibration force, thereby avoiding damage to the transformer body. The two sliding shafts pull the tension spring, thereby forming tension on both sides of the protective inner shell. The tension causes the transformer body and the protective inner shell to stop quickly to reduce wear, thereby providing better protection for the transformer body. The present invention is provided with a connecting block, a connecting piece, an expansion rod, a friction arc plate, a friction sleeve, and a limit plate. When the driving shaft moves left and right, the friction can evenly reduce the vibration force and generate heat, so that the force is converted into heat and dissipated, thereby avoiding that all the force is concentrated on the spring, so that the spring frequently works and eventually reduces the service life of the spring. Friction force is generated between the friction arc plate and the friction sleeve. After the friction force is enhanced, heat can be generated more quickly to reduce the vibration force, so that the protective effect of the promotion force on the spring is further improved, and the service life of the spring is further improved. The present invention is provided with a support plate, a hook, a hanging plate, a telescopic rod and a sliding block. When the support plate is unfolded, the support area of ​​the device is increased, making the device more stable. When the protective shell is hit by other foreign objects and is about to fall, it is supported by the telescopic rod and cannot fall, thereby improving the safety of the device.

[0012] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0013] Please refer to Figures 1-7 , an embodiment of the present invention is: A transformer with a shock-absorbing function, including a transformer body 1, an inner protective shell 2 is fixedly connected to the outer surface of the transformer body 1, sliding seats 21 are fixedly connected to the upper and lower sides of the inner protective shell 2, a horizontal sliding rod 22 is slidably connected to the inner surface of the sliding seat 21, both ends of the horizontal sliding rod 22 are fixedly connected to an outer protective shell 23, vertical sliding rods 24 are fixedly connected to the upper and lower sides of the inner wall of the outer protective shell 23, a sliding shaft 25 is slidably connected to the outer surface of the vertical sliding rod 24, an X-shaped toggle link 26 is hinged to the outside of the sliding shaft 25, the sliding seat 21 slides left and right on the horizontal sliding rod 22 and compresses a spring, and the spring reduces the force of the vibration after absorbing the shock, avoiding damage to the transformer body 1. Energy dissipation devices 3 for dissipating the excess energy during vibration and extending the service life of the shock-absorbing structure are arranged on both sides of the transformer body 1. Support devices 4 for preventing the transformer from tipping over when the vibration amplitude is too large are arranged on both sides of the outer protective shell 23. One side of the X-shaped toggle link 26 away from the sliding shaft 25 is hinged to the inner side of the protection. Springs are arranged between both ends of the sliding seat 21 and both sides of the inner wall of the outer protective shell 23. Two sliding shafts 25 are slidably connected to the upper and lower sides of the vertical sliding rod 24, and a tension spring is arranged between the two sliding shafts 25. The two sliding shafts 25 pull the tension spring, thereby forming a tension on both sides of the inner protective shell 2. The tension enables the transformer body 1 and the inner protective shell 2 to stop quickly and reduce wear, playing a better protective role for the transformer body 1.

[0014] Working principle: When the protective shell 23 and the transformer body 1 are affected by external factors and vibrate, the vibration force is first transmitted to the inner protective shell 2, and then conducted from the inner protective shell 2 to the sliding seat 21. The vibration force causes the sliding seat 21 to slide left and right on the horizontal sliding rod 22 and compress the spring. After the spring absorbs the shock, the vibration force is reduced, avoiding damage to the transformer body 1. When the transformer body 1 and the inner protective shell 2 shake left and right under the influence of vibration, they will squeeze the X-shaped knuckle link 26, causing the X-shaped knuckle link 26 to close. During the closing process of the X-shaped knuckle link 26, the upper and lower sliding shafts 25 are driven to slide towards the upper and lower ends of the vertical sliding rod 24, causing the two sliding shafts 25 to move away from each other. At this time, the two sliding shafts 25 pull the tension spring, thereby forming a tension on both sides of the inner protective shell 2. The tension causes the transformer body 1 and the inner protective shell 2 to quickly stop and reduce wear, playing a better protective role for the transformer body 1.

[0015] Please refer to Figures 1-7 , on the basis of the above embodiment, in another embodiment of the present invention, it includes an energy dissipation device 3. The energy dissipation device 3 includes a push shaft 31, a lead screw 32, and a connecting block 33. The push shaft 31 is fixedly connected to both sides of the inner protective frame. The lead screw 32 is movably connected to the inner surface of the push shaft 31. The connecting block 33 is fixedly connected to the outer surface of the push shaft 31. When the push shaft 31 moves left and right, it rubs against the lead screw 32. Friction can evenly reduce the vibration force and generate heat, dissipating the force as heat, avoiding all the forces concentrating on the spring and causing the spring to do work frequently, ultimately reducing the service life of the spring. The energy dissipation device 3 further includes a connecting member 34, an expansion rod 35, a friction arc plate 36, a friction sleeve 37, and a limiting plate 38. The connecting member 34 is hinged to both sides of the connecting block 33. The expansion rod 35 is hinged to the end of the connecting member 34 away from the connecting block 33. The friction arc plate 36 is fixedly connected to the side of the expansion rod 35 away from the push shaft 31. The friction sleeve 37 is fixedly connected to both sides of the inner wall of the protective shell 23. The limiting plate 38 is fixedly connected to both sides of the inner wall of the protective sleeve. The lead screw 32 rotates through both sides of the protective sleeve. The lead screw 32 is rotatably connected to the inner surface of the limiting plate 38. The limiting plate 38 is fixedly connected to the inner wall of the friction sleeve 37. A first chute is provided on the inner side of the limiting plate 38, and the end of the expansion rod 35 away from the push shaft 31 is slidably connected to the inner surface of the first chute. The lead screw 32 is set as non-self-locking. Friction is generated between the friction arc plate 36 and the friction sleeve 37. After the friction force is enhanced, heat can be generated more quickly to reduce the vibration force, promoting the protective effect of the force on the spring and further improving the service life of the spring.

[0016] Working principle: When the transformer body 1 and the protective inner shell 2 shake left and right, the driving shaft 31 is driven to move left and right. When the driving shaft 31 moves left and right, it rubs the screw rod 32. The friction can evenly reduce the vibration force and generate heat, so that the force is converted into heat and dissipated, avoiding all the force being concentrated on the spring, which makes the spring work frequently and eventually reduces the service life of the spring. When the driving shaft 31 moves and contacts the limit plate 38, the end of the connecting piece 34 hinged to the connecting block 33 moves with the driving shaft 31, and because one end of the expansion rod 35 conflicts with the inner wall of the protective shell 23, when the connecting piece 34 is connected to the connecting block 33, the connecting piece 34 is connected to the connecting block 33. When one hinged end of the connecting block 33 approaches the inner wall of the protective shell 23, the other end thereof pushes the expansion rod 35 outward, causing the expansion rod 35 to slide and open in the slide groove 1. In the process of the expansion rod 35 opening, the friction arc plate 36 is driven to open, and finally the friction arc plate 36 contacts the inner wall of the friction sleeve 37 and becomes a tensioned state. At this time, the pushing shaft 31 moves in the opposite direction to generate friction between the friction arc plate 36 and the friction sleeve 37. After the friction is enhanced, heat can be generated more quickly to reduce the shock force, thereby promoting the protective effect of the force on the spring and further improving the service life of the spring.

[0017] See also Figures 1-7 On the basis of the above embodiment, another embodiment of the present invention includes a support device 4, the support device 4 includes a support block 41, a support plate 42, and a hook 43. The support block 41 is fixedly connected to both sides of the protective shell 23, the support plate 42 is hinged at one end of the support block 41 away from the protective shell 23, and the hook 43 is fixedly connected to one end of the screw rod 32 that passes through the protective shell. After the support plate 42 is unfolded, the support area of ​​the device is increased to make the device more stable. The support device 4 also includes a hanging plate 44, a telescopic rod 45, a sliding Block 46, the hanging plate 44 is fixedly connected to one side of the support plate 42 near the hook 43, the telescopic rod 45 is hinged on both sides of the protective shell 23, the slider 46 is hinged at the bottom end of the telescopic rod 45, a second slide groove is provided on the inner side of the support plate 42, and the slider 46 is slidably connected to the inner surface of the second slide groove, a torsion spring is provided at the hinge point between the support plate 42 and the support block 41, and the telescopic rod 45 is self-locking. When the protective shell 23 is hit by other foreign objects and is about to fall, it is resisted by the telescopic rod 45 and cannot fall, thereby improving the safety of the device.

[0018] Working principle: When the pushing shaft 31 moves left and right on the surface of the lead screw 32, it drives the lead screw 32 to rotate slightly. When the vibration force is too large and causes the pushing shaft 31 to move too far, the rotation amplitude of the lead screw 32 becomes relatively larger. At this time, the lead screw 32 can drive the hook 43 to rotate and disengage from the hanging plate 44. When the hanging plate 44 loses the locking of the hook 43, the torsion spring between the support plate 42 and the support block 41 drives the support plate 42 to rotate and reset to be flush with the ground. During the rotation of the support plate 42, due to gravity, the telescopic rod 45 is pulled to extend. When the telescopic rod 45 reaches the elongation limit, the self-locking mechanism inside locks the two end rods. After the support plate 42 is unfolded, the support area of the device is increased, making the device more stable. When the protective housing 23 is about to fall due to being hit by other external objects, it is resisted by the telescopic rod 45 and thus cannot fall, improving the safety of the device.
