Description

Technical Field

[0001] The utility model relates to the technical field of springs, in particular to a novel energy storage spring. Background Art

[0002] A spring is a mechanical part that uses elasticity to work. Parts made of elastic material deform under external force and return to their original shape when the force is removed. They are also called "springs" and are generally made of spring steel. There are many different types of springs, and by shape, they mainly include coil springs, scroll springs, leaf springs, and special-shaped springs.

[0003] The above technical conditions still have defects: when the existing energy storage spring is in use, its elastic coefficient does not change during use, so when it is pulled by a large force, the deformation of the spring is too large, which can easily cause damage to the spring.

[0004] Based on this, the utility model designs a novel energy storage spring to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a new energy storage spring to solve the above technical problems.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a new energy storage spring, comprising an outer spring, the bottom end and the top end of the outer spring being fixedly connected to a lower mounting seat and an upper mounting seat respectively, an upper top seat and a lower top seat being fixedly connected to the inner sides of the upper mounting seat and the lower mounting seat respectively, an inner spring being fixedly connected to the lower top seat, a driving plate being fixedly connected to the top end of the inner spring, a plug-in column being fixedly connected to the bottom of the upper top seat, a through hole for the plug-in column to pass through being opened inside the driving plate, and a baffle being connected to the bottom end of the plug-in column.

[0007] By adopting the above technical solution, the elastic coefficient of the outer spring after being extended a certain distance can be changed, thereby increasing the functionality of the spring.

[0008] Preferably, a threaded column is fixedly connected to the top of the baffle, a threaded hole is opened inside the plug-in column, and the threaded connection is achieved through the threaded connection between the threaded column and the threaded hole.

[0009] By adopting the above technical solution, the distance between the baffle and the plug-in column can be adjusted, thereby increasing its use effect.

[0010] Preferably, both the lower mounting seat and the upper mounting seat are provided with holes for fixing the two ends of the outer spring.

[0011] By adopting the above technical solution, it is convenient to install the outer spring.

[0012] Preferably, the outer sides of the lower mounting seat and the upper mounting seat are both fixedly connected with mounting rings.

[0013] By adopting the above technical solution, the energy storage spring can be easily connected.

[0014] Preferably, the diameter of the baffle is larger than the diameter of the through hole.

[0015] By adopting the above technical solution, the baffle can contact the driving plate and then drive it.

[0016] To sum up, the present application has the following beneficial technical effects: by setting the baffle and the driving plate, the inner spring can be added to the pulling of the spring only after the outer spring is stretched a certain distance, sharing the pulling force for the outer spring and increasing the use effect of the energy storage spring; and by setting the threaded column, the distance between the baffle and the plug-in column can be adjusted, thereby changing the timing of the inner spring being added when the outer spring is stretched, thereby increasing its use effect.

[0023] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] The following is combined with Figure 1-3 This application is described in further detail.

[0025] Reference Figure 1 and Figure 2 , a new type of energy storage spring, including an outer spring 1, at the bottom and top of the outer spring 1 are respectively fixedly connected to the lower mounting seat 2 and the upper mounting seat 3, and the outer sides of the lower mounting seat 2 and the upper mounting seat 3 are fixedly connected with a mounting ring 4, and the inner sides of the upper mounting seat 3 and the lower mounting seat 2 are respectively fixedly connected with an upper top seat 5 and a lower top seat 6, and an inner spring 7 is fixedly connected to the lower top seat 6, and the top of the inner spring 7 is fixedly connected with a driving plate 8, which abuts against the bottom of the upper top seat 5, and a plug-in column 9 is fixedly connected to the bottom of the upper top seat 5. A through hole for the plug-in column 9 to pass through is opened inside the driving plate 8, and a circular baffle 10 is connected to the bottom end of the plug-in column 9. The diameter of the baffle 10 is larger than the diameter of the through hole, and when the baffle 10 moves upward, the driving plate 8 can be pulled, so that the inner spring 7 can be extended, thereby providing resistance to the deformation of the outer spring 1.

[0026] Furthermore, a threaded column 11 is fixedly connected to the top of the baffle 10, and a threaded hole is opened inside the plug-in column 9. Through the threaded connection between the threaded column 11 and the threaded hole, the distance between the baffle 10 and the plug-in column 9 can be adjusted, thereby changing the distance at which the inner spring 7 participates in the deformation.

[0027] Furthermore, holes are provided on both the lower mounting seat 2 and the upper mounting seat 3 , and the holes are used to lock and fix the two ends of the outer spring 1 .

[0028] The implementation principle of this embodiment is: after the energy storage spring is installed, when the outer spring 1 is stretched, the outer spring 7 is deformed and the length increases, and then the baffle 10 is pressed against the inner side of the driving plate 8, and then the driving plate 8 can be driven to the top, so that the inner spring 7 can also enter the stretching process, so that the outer spring 1 bears the tension, thereby increasing the elastic coefficient of the energy storage spring. When the position of the baffle 10 needs to be adjusted, the baffle 10 can be rotated, and the distance between the baffle 10 and the plug-in column 9 can be adjusted through the threaded connection between the threaded column 11 and the threaded hole, thereby changing the elongation distance of the inner spring 7 participating in the elastic deformation.
