Abstract
Description
Technical Field
[0001] This utility model relates to the field of spring technology, specifically to a spring that facilitates pressure adjustment. Background Technology
[0002] In fields such as machinery manufacturing, automotive engineering, and medical devices, springs, as important elastic components, require flexible adjustment of their pressure output according to actual working conditions.
[0003] Adjustable springs typically consist of a basic spring body, an adjusting assembly, a limiting mechanism, and a locking device. Their working principle is that the initial compression length of the spring is adjusted by changing the position of the adjusting ring. According to Hooke's Law, within the elastic limit, the spring pressure is directly proportional to the deformation. Therefore, changes in pre-compression directly alter the output pressure. The locking device ensures that the adjusted pressure value remains stable. In terms of operation, the user first loosens the locking device, moves the adjusting ring by rotating the screw, adjusts to the target pressure according to the scale or pressure gauge reading, and then locks the locking device after confirmation.
[0004] However, the above-mentioned equipment has obvious shortcomings in use. The elastic force of traditional springs is determined by fixed parameters such as material, wire diameter, and number of coils, and cannot be adjusted after manufacturing. If it is necessary to change the elastic force in actual use, springs of different specifications must be replaced, and multiple models must be stocked. It cannot adapt to dynamic load scenarios. In view of this, we propose a spring that is easy to adjust the pressure. Utility Model Content

[0009] A circular partition plate is fixedly installed inside the mounting cylinder. A circular plate is rotatably installed inside the mounting cylinder. A slotted knob is fixedly installed at the bottom of the circular plate. A screw is fixedly installed at the top of the circular plate.

[0017] Compared with the prior art, this utility model provides a spring that is easy to adjust pressure, and has the following characteristics:
[0018] Beneficial effects:
[0019] 1. This pressure-adjustable spring, to make the device suitable for mechanical structures that require dynamic adjustment of elastic force, is equipped with an adjustment component. This component, in conjunction with rotating a slotted knob, drives the circular plate and screw to rotate. The hexagonal block slides within the hexagonal slot and rises and falls along the screw, pushing the cylinder to move along the mounting cylinder, changing the initial compression of the spring body, thereby precisely controlling the elastic force. The limiting rod slides within the limiting groove, restricting the relative rotation of the cylinder and the mounting cylinder, ensuring that the force direction of the spring body is consistent with the axis. The circular partition separates the installation space to avoid interference between internal components, and the limiting block prevents the hexagonal block from falling off.
[0020] 2. This pressure-adjustable spring, in order to make the device suitable for precision equipment sensitive to noise and vibration, is equipped with an auxiliary component. This component, together with the elastic pad, fits into the numerical groove. When the spring is compressed and extended, it deforms, absorbs the impact force, and reduces vibration transmission. At the same time, the echo groove and the vibration pad form an acoustic buffer space, thereby reducing the operating noise of the spring and avoiding high-frequency resonance. In addition, the numerical groove is marked with adjustment scale, and with the adjustment component, the spring compression can be read intuitively, making it easy to quickly set the target pressure.

[0035] Please see Figures 1-8 This utility model provides a technical solution:
[0036] A spring that facilitates pressure adjustment includes a spring body 1.
[0037] In one embodiment of this utility model, an adjustment assembly 2 is provided on the spring body 1. The adjustment assembly 2 includes a base plate 21, the base plate 21 is fixedly installed at the bottom of the spring body 1, a top plate 22 is fixedly installed above the spring body 1, an installation cylinder 23 is fixedly installed on the base plate 21, a cylinder 24 is fixedly installed on the top plate 22, a circular annular partition 25 is fixedly installed inside the installation cylinder 23, a circular plate 26 is rotatably installed inside the installation cylinder 23, a slotted knob 27 is fixedly installed at the bottom of the circular plate 26, a screw 28 is fixedly installed at the top of the circular plate 26, and a hexagonal slot 29 is formed inside the cylinder 24. A hexagonal block 210 is slidably installed inside the column 24. A limit block 211 is fixedly installed at the top of the screw 28. A limit rod 212 is fixedly installed on the annular partition 25. A limit groove 213 is opened on the column 24. Multiple sets of limit rods 212 and limit grooves 213 are provided. The limit rod 212 slides inside the limit groove 213. The column 24 slides inside the mounting cylinder 23. The mounting cylinder 23 and the column 24 are located inside the spring body 1. The hexagonal block 210 slides inside the hexagonal groove 29. The hexagonal block 210 is threadedly installed on the screw 28. The hexagonal block 210 is located below the limit block 211.
[0038] In this embodiment, when the spring pressure needs to be adjusted, the slotted knob 27 at the bottom of the circular plate 26 is rotated using a tool, causing the circular plate 26 to rotate inside the mounting cylinder 23. This causes the screw 28 at the top of the circular plate 26 to rotate as well. Since the hexagonal block 210 is threaded onto the screw 28 and slides within the hexagonal groove 29 inside the cylinder 24, the rotation of the screw 28 causes the hexagonal block 210 to slide within the hexagonal groove 29 and move up and down along the screw 28. As the hexagonal block 210 moves up and down, it pushes the cylinder 24 to slide inside the mounting cylinder 23. The cylinder 24 is fixedly connected to the top plate 22, and the bottom plate 21 is connected to the bottom of the spring body 1. The spring body 1 is fixed, which changes the initial compression of the spring body 1, thereby precisely controlling the spring force. During the sliding of the cylinder 24, the limiting rod 212 on the annular partition 25 slides in the limiting groove 213 on the cylinder 24, which restricts the relative rotation between the cylinder 24 and the mounting cylinder 23, ensuring that the force direction of the spring body 1 is consistent with the axis. The annular partition 25 can also separate the internal space of the mounting cylinder 23 to avoid interference between internal components. The limiting block 211 at the top of the screw 28 can prevent the hexagonal block 210 from falling off the screw 28, ensuring the stable operation of the adjusting component 2, making the spring suitable for mechanical structures that require dynamic adjustment of the spring force.
[0039] In one embodiment of this utility model, an auxiliary component 3 is provided on the mounting cylinder 23. The auxiliary component 3 includes a numerical groove 31. An elastic pad 32 is fixedly installed on the mounting cylinder 23. An echo groove 33 is opened on the mounting cylinder 23. A vibration pad 34 is fixedly installed inside the mounting cylinder 23. Multiple sets of numerical groove 31, elastic pad 32, echo groove 33 and vibration pad 34 are provided. The elastic pad 32 is located above the echo groove 33. The vibration pad 34 is located inside the echo groove 33. The elastic pad 32 is in contact with the numerical groove 31.
[0040] In this embodiment, when the spring body 1 is compressed and extended, the elastic pad 32 on the mounting cylinder 23 fits against the numerical groove 31, and the elastic pad 32 will deform, thereby absorbing the impact force and reducing the transmission of vibration to the outside. At the same time, the echo groove 33 on the mounting cylinder 23 and the internal vibration pad 34 form an acoustic buffer space. The vibration pad 34 can further weaken the vibration, and the echo groove 33 can buffer and dissipate the sound, thereby reducing the noise generated when the spring is working and avoiding high-frequency resonance. This makes the spring suitable for precision equipment that is sensitive to noise and vibration. In addition, the numerical groove 31 is marked with an adjustment scale. When adjusted with the adjustment component 2, the compression of the spring can be read intuitively, which facilitates the quick setting of the target pressure.

The specific connection methods of each part are all conventional methods such as riveting and welding that are mature in the prior art. The machinery, parts and equipment are all conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art.

[0042] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
