Description

Technical Field

[0001] The utility model relates to the technical field of compression springs, in particular to a high-temperature resistant nickel-based alloy compression spring. Background Art

[0002] High temperature resistant nickel base alloy compression springs are a special type of spring made from nickel base alloy materials specifically designed to maintain their mechanical properties and structural integrity in high temperature environments.

[0003] The patent specification with the announcement number CN221443171U discloses an adjustable compression spring, including a connecting component 1, a connecting component 2 and an elastic force adjustment component; the connecting component 2 is located inside the connecting component 1, and the elastic force adjustment component is located between the connecting component 1 and the connecting component 2. The advantage of the utility model over the existing technology is that the utility model can adjust the elastic force in a small range according to the usage conditions, and has a wider range of application.

[0004] However, in the implementation of relevant technologies, it was found that the above-mentioned adjustable compression spring has the following problems: the device twists the spring by rotating the adjusting ring, thereby changing the elastic force of the spring. Since the adjusting ring and the connecting ring are limited only by the elastic force of the spring, when the spring rebounds after being compressed, due to the resilience of the spring, the spring will drive the adjusting ring and the connecting ring to move upward. When the resilience of the spring is large, it is easy to cause the connecting ring to disengage from the slot. At this time, the adjusting ring and the connecting ring will rotate under the torsion of the spring, causing the spring to return to its initial state, making the device ineffective in adjusting the elastic force of the spring, thereby reducing the device's adjustment effect on the elastic force of the spring. In view of this, a high-temperature resistant nickel-based alloy compression spring is provided to overcome the above-mentioned defects. Utility Model Content

Moving the push plate of the device can limit or release the limit of the connecting block by the limiting shaft, so that the limiting shaft does not affect the elastic adjustment efficiency of the spring body, so that when the spring body compresses and rebounds, the rotating sleeve and the connecting block cannot be driven to move, thereby improving the stability when the rotating sleeve and the connecting block are placed, thereby improving the stability after the elastic force of the spring body is adjusted, and thereby improving the adjustment effect of the device on the elastic force of the spring body;

[0016] A high-temperature resistant nickel-based alloy compression spring designed by the utility model, through designed cooperation, when the elastic force changed by rotating the spring body is limited and cannot meet the adjustment requirement of the elastic force of the spring body, move the two push plates, so that the limiting shaft disengages from the connecting block, and move the rotating sleeve upward, so that the spring body is shortened, increasing the elastic force of the spring body, move the rotating sleeve downward, so that the spring body is elongated, reducing the elastic force of the spring body, so that the adjustment range of the elastic force of the spring body can be further increased. When the elastic force of the spring body is adjusted, the push plate is released, and the limiting shaft is pushed into the corresponding limiting hole in the connecting block by squeezing the spring. At this time, the rotating sleeve and the connecting block are limited. When the elastic force of the spring body is adjusted, rotate the bolt, so that the bolt squeezes the fixed sleeve, so that the connection between the rotating sleeve, the connecting block and the fixed sleeve is more stable, thereby further improving the stability when the spring body is placed, so that the device further improves the adjustment range of the elastic force of the spring body, and thereby further improves the adjustment effect of the device on the elastic force of the spring body.

[0024] As a further implementation of the above technical solution: a plurality of limiting holes are opened on one side of the plurality of connecting blocks 7, and the side surfaces of the two limiting shafts 11 are respectively fitted with the inside of the corresponding two limiting holes, and the limiting shafts 11 are convenient for limiting the connecting blocks 7.

[0025] As a further implementation of the above technical solution: movable grooves are opened inside both of the two mounting seats 9, and the side surfaces of the two movable grooves are respectively slidably connected with the side surfaces of the two movable plates 10, and the movable plates 10 are convenient for driving the limiting shafts 11 to move.

[0026] As a further implementation of the above technical solution: positioning holes are provided on one side of each of the two mounting seats 9, and the inner parts of the two positioning holes are respectively in contact with the sides of the two limiting shafts 11. The mounting seats 9 facilitate improving the stability of the movable plate 10 during movement.

[0027] As a further implementation of the above technical solution: placing holes are provided on the other side of each of the two mounting seats 9, and the inner parts of the two placing holes are respectively in contact with the sides of the two movable rods 13. The movable rods 13 facilitate driving the movable plate 10 to move.

[0028] As a further implementation of the above technical solution: a rotating groove is provided inside the rotating sleeve 6, and the inner part of the rotating groove is in contact with the side of the fixed sleeve 2. The rotating sleeve 6 facilitates driving the spring body 5 to rotate.

[0029] During specific implementation: the device can be easily installed with a connecting member through the first flange 1 and the second flange 4. The fixed sleeve 2 and the telescopic rod 3 facilitate preventing the spring body 5 from bending when being compressed. When the initial elastic force of the spring body 5 is too large or too small to meet the requirements, push the two pushing plates 14, thereby driving the two pushing plates 14 to move away from each other, thereby driving the two movable rods 13 to move away from each other, thereby driving the two movable plates 10 to move away from each other, thereby driving the two limiting shafts 11 to move away from each other, such that the limiting shafts 11 are disengaged from the connection block 7. At this time, move the rotating sleeve 6 upward, thereby causing the connection block 7 to be disengaged from the connection groove. Then drive the rotating sleeve 6 to rotate, thereby driving the spring body 5 to rotate, increasing the elastic force of the spring body 5. Drive the rotating sleeve 6 to reverse, thereby driving the spring body 5 to reverse, reducing the elastic force of the spring body 5. After the elastic force of the spring body 5 is adjusted, move the rotating sleeve 6 downward, thereby driving the connection block 7 to move downward, such that the connection block 7 enters the connection groove. Release the pushing plates 14, and by squeezing the spring 12, push the two movable plates 10 to move closer to each other, thereby driving the two limiting shafts 11 to move closer to each other, such that the limiting shafts 11 enter the corresponding limiting holes in the connection block 7, thereby limiting the connection block 7, and thus limiting the rotating sleeve 6 and preventing it from moving. Moving the pushing plates 14 can limit or release the connection block 7 by the limiting shafts 11, such that the limiting shafts 11 do not affect the elastic adjustment efficiency of the spring body 5. Therefore, when the spring body 5 is compressed and rebounds, it cannot drive the rotating sleeve 6 and the connection block 7 to move, thereby improving the stability of the rotating sleeve 6 and the connection block 7 during placement, thereby improving the stability after the elastic force of the spring body 5 is adjusted, and thus improving the adjustment effect of the device on the elastic force of the spring body 5.

[0030] As a further implementation of the above technical solution: a number of threaded holes 15 are provided inside the rotating sleeve 6, and bolts 16 are threadedly connected to the interiors of the number of threaded holes 15. The bolts 16 facilitate fixing the rotating sleeve 6 and the fixed sleeve 2 together.

[0031] As a further implementation of the above technical solution: Rubber rings 17 are provided on the sides of several bolts 16, and one side of each of the several rubber rings 17 is in contact with the side of the rotating sleeve 6. The rubber rings 17 facilitate buffering the vibration transmitted to the bolts 16 and reducing the probability of damage to the bolts 16.

[0032] During specific implementation: Since the elastic force changed by the rotating spring body 5 is limited, when the adjustment requirement for the elastic force of the spring body 5 cannot be met, move the two push plates 14, thereby driving the two push plates 14 to move away from each other, thereby driving the two movable rods 13 to move away from each other, thereby driving the two movable plates 10 to move away from each other, thereby driving the two limit shafts 11 to move away from each other, causing the limit shafts 11 to disengage from the connecting block 7, move the rotating sleeve 6 upward, thereby shortening the spring body 5, increasing the elastic force of the spring body 5, move the rotating sleeve 6 downward, thereby elongating the spring body 5, reducing the elastic force of the spring body 5, so that the adjustment range of the elastic force of the spring body 5 can be further increased. After the elastic force of the spring body 5 is adjusted, release the push plates 14, and push the two movable plates 10 to move closer to each other by squeezing the spring 12, thereby driving the two limit shafts 11 to move closer to each other, causing the limit shafts 11 to enter the corresponding limit holes in the connecting block 7. At this time, the rotating sleeve 6 and the connecting block 7 are limited, so that the elastic force adjustment of the spring body 5 is completed. When the elastic force of the spring body 5 is adjusted, rotate the bolt 16 so that the bolt 16 squeezes the fixed sleeve 2, thereby making the connection between the rotating sleeve 6, the connecting block 7 and the fixed sleeve 2 more stable, thereby further improving the stability of the rotating sleeve 6 and the connecting block 7 when placed, and further improving the stability of the spring body 5 when placed. Buffer the impact force received by the bolt 16 through the rubber ring 17 and reduce the damage of vibration to the bolt 16, so that the device further increases the adjustment range of the elastic force of the spring body 5, and further improves the adjustment effect of the elastic force of the spring body 5 of the device.
