Description

Technical Field

[0001] This invention belongs to the field of current stabilizer technology, specifically an improved two-stage current stabilizer. Background Technology

[0002] A large two-stage current regulator is a device that can provide a constant and adjustable large current output. In some complex circuit systems, multiple stages of current regulation may be needed to further improve current stability. In this case, a two-stage current regulator is a second regulator connected in series or parallel in the circuit to further stabilize the current that has already undergone the first-stage current regulation. This design is usually used in applications with extremely high requirements for current stability. It can maintain the stability of the output current under changes in input voltage and load impedance, thereby protecting the load devices from the effects of current fluctuations and ensuring the normal operation of the circuit and system.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] (1) During operation, the operator places the large secondary current stabilizer body into the mounting base. Then, the operator rotates the crank handle to drive the first shaft to rotate along the inside of the first bushing on the support frame. When the first shaft rotates, it drives the first sprocket to rotate. When the first sprocket rotates, it drives the two second sprockets to rotate along the two connecting frames through the chain. When the first sprocket rotates, it drives the second bevel gear to rotate through the first bevel gear. When the second bevel gear rotates, it drives the second shaft to rotate along the positioning frame and the two second bushings. When the second shaft rotates, it drives the protective cover to rotate and close through the two fixed sleeves and the two support arms, thereby covering and protecting the large secondary current stabilizer body and preventing damage to the large secondary current stabilizer body caused by accidental collision.

[0015] (2) When the two second sprockets rotate, they drive the two third shafts to rotate along the inside of the third bushing. When the two third shafts rotate, they drive the fourth bevel gear to rotate along the shaft seat on the fixed seat through the third bevel gear. When the fourth bevel gear rotates, it drives the threaded rod to rotate along the positioning seat. When the two threaded rods rotate, they drive the two threaded sleeves on their surfaces to move towards each other. When the two threaded sleeves move, they drive the first slider to slide along the inside of the first slide groove through the connecting block, which increases the stability of the two threaded sleeves when they move. When the two threaded sleeves move towards each other, they drive the two pushing plates to move towards each other through the support column. When the two pushing plates move towards each other, they push the transmission platform upward through two rollers and two rotating frames. When the transmission platform moves, it drives the two second sliders to slide along the inside of the two second slide grooves through two connecting rods, which increases the stability of the transmission platform when it moves. When the transmission platform moves upward, it pushes the two clamping rods to rotate along the two rotating shafts through two gravity balls. The two gravity balls can reset the two clamping rods by gravity rotation. When the two clamping rods rotate, they will clamp the two positioning buckles on the body of the large secondary current regulator, thereby positioning and fixing the body of the large secondary current regulator, and thus quickly completing the installation.

[0016] (3) This makes the positioning and installation of this large secondary current stabilizer very convenient, reduces the workload of the staff, improves the installation efficiency, and has good protection capabilities, which improves its service life and ensures the normal operation of the circuit.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0028] Example 1, by Figures 1 to 7The present invention includes a mounting base 1, with support legs 2 fixedly mounted at each of the four bottom corners of the mounting base 1. A protective cover 3 is provided on one side of the upper part of the mounting base 1. A large secondary current regulator body 38 is provided inside the mounting base 1. Positioning buckles 39 are fixedly mounted on both sides of the surface of the large secondary current regulator body 38. Two clamping rods 4 are symmetrically mounted on both sides of the upper part of the interior of the mounting base 1 via two rotating shafts 5. Gravity balls 40 are fixedly mounted at the bottom ends of the two clamping rods 4. A support frame 6 is fixedly mounted on the upper rear side of the mounting base 1. A first bushing 7 is fixedly mounted in the middle of the upper part of the support frame 6. An internal rotating first shaft 8 is mounted, with a crank 9 fixedly mounted at one end of the first shaft 8. A transmission assembly is provided at the end of the first shaft 8 away from the crank 9. The transmission assembly is connected to the protective cover 3 and two clamping rods 4. When the crank 9 drives the first shaft 8 to rotate, the first shaft 8 outputs power to the protective cover 3 and the two clamping rods 4 through the transmission assembly, causing the protective cover 3 to rotate and close, covering the large secondary current regulator body 38 for protection. The two clamping rods 4 rotate and press the two positioning buckles 39 on the large secondary current regulator body 38, allowing for quick installation and positioning of the large secondary current regulator body 38.

[0029] During operation, the operator places the large secondary current regulator body 38 into the mounting base 1. Then, the operator rotates the crank handle 9 to drive the first shaft 8 to rotate along the inside of the first bushing 7 on the support frame 6. When the first shaft 8 rotates, it drives the transmission component to operate. When the transmission component operates, it drives the protective cover 3 to rotate and close, thereby covering and protecting the large secondary current regulator body 38 to prevent damage to the large secondary current regulator body 38 caused by accidental collision.

[0030] While the transmission component is operating, it also pushes two clamping rods 4 to rotate along two rotating shafts 5 via two gravity balls 40. The two gravity balls 40 allow the two clamping rods 4 to reset by gravity rotation. When the two clamping rods 4 rotate, they press the two positioning buckles 39 on the large secondary current regulator body 38, thereby positioning and fixing the large secondary current regulator body 38, and thus quickly completing the installation. This makes the positioning and installation of this large secondary current regulator very convenient, reduces the workload of the staff, improves the installation efficiency, and has good protection capabilities, extending its service life and ensuring the normal operation of the circuit.

When the first sprocket 10 rotates, it drives the two second sprockets 19 to rotate along the two connecting frames 18 via the chain 20. When the first sprocket 10 rotates, it drives the second bevel gear 12 to rotate via the first bevel gear 11. When the second bevel gear 12 rotates, it drives the second shaft 13 to rotate along the positioning frame 17 and the two second shaft sleeves 14. When the second shaft 13 rotates, it drives the protective cover 3 to rotate and close via the two fixed sleeves 41 and the two support arms 16, thereby covering and protecting the large secondary current regulator body 38 and preventing damage to the large secondary current regulator body 38 from accidental collisions.

[0033] In Example 3, based on Example 2, a third shaft 21 is fixedly installed on the side of the second sprocket 19 away from the connecting frame 18. One end of each of the two third shafts 21 extends into the interior of the mounting base 1 and is fixedly installed with a third bevel gear 23.

A positioning seat 33 is rotatably installed on the opposite ends of the two threaded rods 27, and the bottom of each positioning seat 33 is fixedly connected to the inner bottom of the mounting base 1. A threaded sleeve 2 is threadedly connected to the surface of each threaded rod 27. 8. The bottom of each of the two threaded sleeves 28 is fixedly mounted with a first slider 30 via a connecting block 29. The bottom of the mounting base 1 is provided with first grooves 34 on both sides. The two first sliders 30 are slidably mounted inside the two first grooves 34 respectively. The top of each of the threaded sleeves 28 is fixedly mounted with a support column 31. The top of each of the two support columns 31 is fixedly mounted with a push plate 32.

The top of each of the two rotating frames 36 is fixedly mounted with a transmission table 37. The upper surface of each transmission table 37 is in contact with the gravity ball 40 at the bottom of each of the two clamping rods 4.

The inner walls of the front and rear sides of the mounting base 1 are provided with second grooves 44. The two second sliders 43 are slidably mounted inside the two second grooves 44.

[0034] When the two second sprockets 19 rotate, they drive the two third shafts 21 to rotate along the inside of the third bushing 22. When the two third shafts 21 rotate, they drive the fourth bevel gear 24 to rotate along the shaft seat 25 on the fixed seat 26 via the third bevel gear 23. When the fourth bevel gear 24 rotates, it drives the threaded rod 27 to rotate along the positioning seat 33. When the two threaded rods 27 rotate, they drive the two threaded sleeves 28 on their surfaces to move towards each other. When the two threaded sleeves 28 move, they drive the first slider 30 along the inside of the first groove 34 via the connecting block 29. The sliding mechanism increases the stability of the two threaded sleeves 28 when they move. When the two threaded sleeves 28 move towards each other, they drive the two pushing plates 32 to move towards each other through the support column 31. When the two pushing plates 32 move towards each other, they push the transmission table 37 upward through the two rollers 35 and the two rotating frames 36. When the transmission table 37 moves, it drives the two second sliders 43 to slide along the inside of the two second sliding grooves 44 through the two connecting rods 42, which increases the stability of the transmission table 37 when it moves. When the transmission table 37 moves upward, it pushes the two gravity balls 40.
