Abstract
Description
Technical Field
[0001] This utility model relates to the field of high-strength shock-absorbing spring technology, specifically a high-strength shock-absorbing spring for engineering machinery. Background Technology
[0002] Vibration damping springs are key components in mechanical systems used to absorb vibration and impact energy. They are widely used in automobiles, industrial equipment, building structures and other fields. Their core function is to convert kinetic energy into potential energy through elastic deformation and then dissipate energy through damping effect, thereby reducing the vibration amplitude and frequency of equipment or structure.
[0003] As people's lives continue to change, the use of shock-absorbing springs has become increasingly common. However, traditional shock-absorbing springs are not easy to adjust in terms of elasticity, which greatly limits their use. Therefore, a new structure is proposed to solve this technical problem. Utility Model Content
[0004] (a) Technical problems to be solved
[0005] To address the shortcomings of existing technologies, this utility model provides a high-strength shock-absorbing spring for engineering machinery, which has advantages such as easy adjustment of the spring force, and solves the problems mentioned in the background art.
[0006] (II) Technical Solution
[0007] To achieve the purpose of facilitating the adjustment of elastic force mentioned in the background art, this utility model provides the following technical solution: a high-strength shock-absorbing spring for engineering machinery, comprising a spring, an upper side plate fixedly connected to the upper end of the spring, an upper tube provided on one side of the outer surface of the upper side plate, a device tube provided inside the upper side tube, a movable rod provided inside the device tube, a device plate provided on one side of the inner wall of the upper side tube, a lower side plate fixedly connected to the lower end of the spring, a lower tube fixedly connected to the upper side of the outer surface of the lower side plate, an upper and lower sliding groove provided on one side of the outer surface of the lower side tube, a sliding rod provided inside the upper and lower sliding groove, an auxiliary plate provided at one end of the sliding rod, a threaded rod provided on one side of the outer surface of the auxiliary plate, and a limit cap provided at one end of the threaded rod.
[0008] Preferably, there are two device tubes, and the two device tubes are evenly arranged inside the upper tube.
[0009] Preferably, there are two movable rods, and the two movable rods are evenly arranged inside the device tubes on the left and right sides.
[0010] Preferably, there are two device plates, and the two device plates are evenly arranged on the left and right sides of the inner wall of the upper tube.
[0011] Preferably, one side of the outer surface of the device plate contacts one side of the inner wall of the upper tube, and penetrates one side of the inner wall of the upper tube to one side of the outer surface of the upper tube, and is fixedly connected to the upper tube.
[0012] Preferably, there are two upper and lower sliding grooves, and the two upper and lower sliding grooves are evenly arranged on the left and right sides of the outer surface of the lower tube. One side of the outer surface of the upper and lower sliding grooves contacts one side of the outer surface of the lower tube and penetrates one side of the outer surface of the lower tube to one side of the inner wall of the lower tube, and is fixedly connected to the lower tube.
[0013] An auxiliary groove is provided on one side of the inner wall of the device tube, and one side of the outer surface of the auxiliary groove contacts one side of the inner wall of the device tube and penetrates one side of the inner wall of the device tube to one side of the outer surface of the upper tube. A movable rod is set inside the device tube, and a toggle rod is provided on one side of the outer surface of the movable rod. One end of the toggle rod is fixedly connected to one side of the outer surface of the movable rod, and the other end of the toggle rod penetrates through the auxiliary groove to one side of the outer surface of the upper tube and is slidably connected to the auxiliary groove. This allows the toggle rod to drive the movable rod to move up and down when it moves up and down. The distance from the lowest side of the auxiliary groove to the upper end of the lower tube is greater than the height of the upper and lower sliding grooves. This ensures that when the sliding rod moves to the lowest end of the upper and lower sliding grooves, the upper end of the lower tube will not contact the auxiliary groove. This ensures that the upper tube will not affect the toggle rod and the movable rod when it moves up and down.
[0014] A device hole is provided on one side of the outer surface of the device plate, and one end of the device hole contacts one side of the outer surface of the device plate and penetrates one side of the outer surface of the device plate to the other side of the outer surface of the device plate. The sliding rod is adapted to the specifications of the upper and lower sliding grooves and is adapted to the device hole. When the sliding rod is slidably connected to the upper and lower sliding grooves, and when the sliding rod is inserted into the device hole, the upper tube can move up and down in the lower tube, and the range of movement is the height of the upper and lower sliding grooves.
[0015] Furthermore, the limiting slot is compatible with the auxiliary plate. When the limiting slot is engaged with the auxiliary plate, rotating the threaded rod causes the threaded rod to press against the limiting slot, which in turn causes the limiting slot to press against the lower tube. This results in greater friction when the upper tube moves up and down.
[0016] Compared with the prior art, this utility model provides a high-strength shock-absorbing spring for engineering machinery, which has the following beneficial effects:
[0017] 1. This utility model, through the sliding rod set in the device, when the sliding rod is inserted into the device plate, causes the movable rod to be inserted into the sliding rod, and the limiting cap is placed on one side of the outer surface of the auxiliary plate. By rotating the threaded rod, the threaded rod passes through the threaded connection between the limiting cap and the sliding rod. As the threaded rod is continuously rotated, the limiting cap is squeezed against the lower tube, increasing the friction between the limiting cap and the lower tube. This causes the spring to require greater pressure when moving downward and greater elastic force when moving upward, thus allowing the elastic force of the device to be adjusted.
[0018] 2. This utility model, by setting an upper side plate and a lower side plate inside the device, with the upper side plate and the lower side plate having the same specifications and connecting holes on their outer surfaces, allows the device to be used directly without distinguishing between the upper and lower ends, making it more convenient to use.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figures 1-3 A high-strength shock-absorbing spring for engineering machinery, comprising spring 1;
[0025] like Figures 1-3As shown, an upper side plate 2 is fixedly connected to the upper end of spring 1. An upper tube 3 is provided on one side of the outer surface of the upper side plate 2. A device tube 4 is provided inside the upper side tube 3. A movable rod 5 is provided inside the device tube 4. A device plate 6 is provided on one side of the inner wall of the upper side tube 3. A lower side plate 7 is fixedly connected to the lower end of spring 1. A lower tube 8 is fixedly connected to the upper side of the outer surface of the lower side plate 7. An upper and lower sliding groove 9 is provided on one side of the outer surface of the lower tube 8. A sliding rod 10 is provided inside the upper and lower sliding groove 9. An auxiliary plate 11 is provided at one end of the sliding rod 10. A threaded rod 12 is provided on one side of the outer surface of the auxiliary plate 11. A limit cap 13 is provided at one end of the threaded rod 12.
[0026] Specifically, such as Figures 1-3 As shown, there are two device tubes 4, and the two device tubes 4 are evenly arranged inside the upper tube 3.
[0027] Specifically, such as Figures 1-3 As shown, there are two movable rods 5, and the two movable rods 5 are evenly arranged in the device tubes 4 on the left and right sides.
[0028] Specifically, such as Figures 1-3 As shown, there are two device plates 6, and the two device plates 6 are evenly arranged on the left and right sides of the inner wall of the upper tube 3.
[0029] Specifically, such as Figures 1-3 As shown, one side of the outer surface of the device plate 6 contacts one side of the inner wall of the upper tube 3, and penetrates one side of the inner wall of the upper tube 3 to one side of the outer surface of the upper tube 3, and is fixedly connected to the upper tube 3.
[0030] Specifically, such as Figures 1-3 As shown, there are two upper and lower sliding grooves 9, and the two upper and lower sliding grooves 9 are evenly arranged on the left and right sides of the outer surface of the lower tube 8. One side of the outer surface of the upper and lower sliding grooves 9 contacts one side of the outer surface of the lower tube 8, and penetrates one side of the outer surface of the lower tube 8 to one side of the inner wall of the lower tube 8, and is fixedly connected to the lower tube 8.
[0031] Through the above technical solution, an auxiliary groove is provided on one side of the inner wall of the device tube 4, and the outer surface of the auxiliary groove contacts the inner wall of the device tube 4 and penetrates through the inner wall of the device tube 4 to the outer surface of the upper tube 3. The movable rod 5 is provided inside the device tube 4, and a toggle rod is provided on one side of the outer surface of the movable rod 5. One end of the toggle rod is fixedly connected to the outer surface of the movable rod 5, and the other end of the toggle rod penetrates through the auxiliary groove to the outer surface of the upper tube 3 and is slidably connected to the auxiliary groove. This allows the toggle rod to drive the movable rod 5 to move up and down when it moves up and down. The distance from the lowest side of the auxiliary groove to the upper end of the lower tube 8 is greater than the height of the upper and lower sliding grooves 9. This ensures that when the sliding rod 10 moves to the lowest end of the upper and lower sliding grooves 9, the upper end of the lower tube 8 will not contact the auxiliary groove. This ensures that the upper tube 3 will not affect the toggle rod and the movable rod 5 when it moves up and down.
[0032] A device hole is provided on one side of the outer surface of the device plate 6, and one end of the device hole contacts one side of the outer surface of the device plate 6 and passes through one side of the outer surface of the device plate 6 to the other side of the outer surface of the device plate 6. The sliding rod 10 is adapted to the specifications of the upper and lower sliding grooves 9 and is adapted to the device hole. When the sliding rod 10 is slidably connected to the upper and lower sliding grooves 9, and when the sliding rod 10 is inserted into the device hole, the upper tube 4 can move up and down in the lower tube 8, and the range of movement is the height of the upper and lower sliding grooves 9.
[0033] Furthermore, the limiting slot 13 is adapted to the auxiliary plate 11, and when the limiting slot 13 is engaged with the auxiliary plate 11, the threaded rod 12 is rotated to squeeze the limiting slot 13, which in turn squeezes the lower tube 8, resulting in greater friction when the upper tube 3 moves up and down.
[0034] In use, the upper tube 3 and the lower tube 8 are inserted together, and then the slide rod 10 passes through the upper and lower sliding grooves 9 and is inserted into the device plate 6. Then the upper limit cap 13 is engaged, and the threaded rod 12 is rotated so that the upper limit groove 13 presses against the upper tube 3, which changes the friction between the upper tube 3 and the lower tube 8. This allows the elasticity of the device to change during use. When the elasticity is adjusted to a suitable level, the device can be used normally.
[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
