Description

Technical Field

[0001] This utility model belongs to the field of springs, and specifically relates to an adjustable spring. Background Technology

[0002] A spring is an elastic element with elastic restoring function. In the mechanical field, it is often used for load-bearing and shock absorption. The elastic force required in traditional mechanical parts can only be accomplished by using a spring of the corresponding model. If greater or less elasticity is required, the spring needs to be replaced. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in the prior art by providing an adjustable spring.

[0004] The purpose of this utility model can be achieved through the following technical solution: an adjustable spring, including a spring body and a plurality of support columns for supporting the spring body, characterized in that the support columns pass through the spring body respectively, and are arranged symmetrically in pairs;

[0005] The support column is provided with a groove, a telescopic rod is provided in the groove, the telescopic rod is provided with an installation groove, an installation rod is provided in the installation groove, the installation rod is provided with a foldable buckle, and the buckle is provided with a rotating shaft for cooperating with the installation rod.

[0006] The mounting groove has an inclined groove above it for folding the buckle part, and a support part is provided below it for connecting the telescopic part. The support part abuts against the buckle part.

[0007] In the aforementioned adjustable spring, the support column is provided with several limiting grooves that communicate with the channel, and the openings of the limiting grooves face the side of the spring body.

[0008] In the aforementioned adjustable spring, the telescopic rod has a through hole, and a pull rope part connected to the upper part of the buckle part is provided in the through hole. One end of the pull rope part is connected to the buckle part, and the other end extends to the upper part of the through hole, and a pull ring is provided for convenient pulling of the pull rope part.

[0009] In the aforementioned adjustable spring, a guide groove is provided on the inner wall of the channel located on one side of the limiting groove.

[0010] Compared with existing technologies, this adjustable spring increases or decreases the spring's elasticity by fixing the number of spring coils through a snap-fit ​​part, making the spring suitable for different elastic movements and avoiding the problem of needing to replace the spring to adjust the elastic force.

[0014] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0015] like Figure 1 , Figure 2 As shown, this adjustable spring includes a spring body 1 and several support columns 2 for supporting the spring body 1. The support columns 2 pass through the spring body 1 respectively and are arranged symmetrically in pairs.

[0016] The support column 2 has a groove 3, a telescopic rod 4 is installed in the groove 3, the telescopic rod 4 has an installation groove 5, the installation groove 5 has an installation rod 6, the installation rod 6 has a foldable buckle part 7, and the buckle part 7 has a rotating shaft 8 for cooperating with the installation rod 6.

[0017] The mounting groove 5 has an inclined groove 9 above it for folding the buckle part 7, and a support part 10 is provided below the mounting groove 5 for connecting the telescopic part. The support part 10 abuts against the buckle part 7.

[0018] During use, when the telescopic rod 4 is pushed downward, the buckle 7 folds over from the rotation axis 8 and gradually tilts until the buckle 7 disengages from the limiting groove 11. As the telescopic rod 4 moves downward, the front end of the buckle 7 will contact the next limiting groove 11, and due to gravity, the front end of the buckle 7 will extend out of the limiting groove 11. At this time, an upward pulling force is applied to the telescopic rod 4, making the buckle 7 perpendicular to the limiting groove 11, which shortens the stretching distance of the spring body 1 and reduces the elastic force.

[0019] When resetting, push the telescopic rod 4 downwards, and the buckle 7 will fold from the rotation axis 8 and gradually tilt until the buckle 7 disengages from the limiting groove 11. At this time, pull the pull ring 14 to keep the buckle 7 still, and then pull the telescopic rod 4 upwards until the buckle 7 reaches the uppermost limiting groove 11.

[0020] When the latching part 7 is perpendicular to the limiting groove 11, the support column 2 moves to both sides. The latching part 7 will not fold down due to the obstruction of the support part 10, thereby causing the spring body 1 to stretch.

[0021] To elaborate further, the support column 2 has several limiting grooves 11 that are connected to the channel 3, and the openings of the limiting grooves 11 face the side of the spring body 1.

[0022] To elaborate further, the telescopic rod 4 has a through hole 12, and a pull rope part 13 connected to the upper part of the buckle part 7 is provided in the through hole 12. One end of the pull rope part 13 is connected to the buckle part 7, and the other end extends to the upper part of the through hole 12, and a pull ring 14 is provided for easy pulling of the pull rope part 13.

[0023] To elaborate further, a guide groove 15 is provided on the inner wall of the channel 3 located on one side of the limiting groove 11 to prevent the opening from shifting during movement.

[0024] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0025] Although this document frequently uses terms such as spring body 1, support column 2, groove 3, telescopic rod 4, mounting groove 5, mounting rod 6, buckle part 7, rotating shaft 8, inclined groove 9, support part 10, limiting groove 11, through hole 12, pull rope part 13, pull ring 14, guide groove 15, etc., the possibility of using other terms is not excluded. The use of these terms is merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
