Technical Field
[0001] This utility model relates to the field of rotating shaft technology, specifically to an impact-resistant rotating shaft structure. Background Technology
[0002] A shaft is a mechanical connection device that allows relative rotational movement between two or more components. Through specific design, it transmits and constrains rotational force within a predetermined range, while simultaneously bearing axial force, radial force, or torque.
[0003] Existing shafts have poor impact resistance, making them prone to breakage under external impacts. This affects the normal use of the shaft and reduces its service life. Furthermore, the poor vibration damping of the shaft causes it to vibrate in addition to the impact force, reducing its buffering and protection effect and thus the overall practicality of the shaft structure. Utility Model Content
[0004] The purpose of this invention is to provide an impact-resistant shaft structure to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: an impact-resistant rotating shaft structure, comprising a cylindrical body, a rotating shaft component disposed inside the cylindrical body, a first spring disposed between the rotating shaft component and the cylindrical body, a plurality of wedge blocks fixedly and radially slidably disposed inside the cylindrical body, a second spring disposed between each of the plurality of wedge blocks and the cylindrical body, and a plurality of wedge grooves that cooperate with the wedge blocks being formed on the circumferential surface of the rotating shaft component.
[0006] The aforementioned components achieve the following effects: by utilizing the first spring, the rotating shaft can be buffered during impact, thereby protecting it; and by utilizing the second spring, the vibration generated by the rotating shaft during impact can be transmitted to the wedge blocks, thereby enabling multiple wedge blocks to dampen the vibration of the rotating shaft during impact, further improving the impact resistance of the rotating shaft.
[0007] Preferably, a threaded cylinder is rotatably disposed on one end face of the cylinder body, and a threaded rod is threadedly connected inside the threaded cylinder, and the threaded rod is coaxially disposed on one end face of the rotating shaft.
[0008] The aforementioned components achieve the following effect: by utilizing the threaded rod and threaded cylinder, the rotating shaft components inside the cylinder can be easily disassembled and assembled quickly, thereby facilitating the rapid replacement of the rotating shaft components inside the cylinder and improving the practicality of the entire rotating shaft structure.
[0009] Preferably, a limiting plate is fixedly installed on the circumferential surface of the threaded rod, and the limiting plate movably abuts against the end face of the threaded cylinder.
[0010] The effect achieved by the above-mentioned components is that, by using the limiting plate, the assembly position of the rotating shaft can be restricted.
[0011] Preferably, one end of the first spring is fixedly connected to the end face of the threaded rod, and a groove is provided on the end face of the rotating shaft near the threaded rod, and the other end of the first spring is fixedly connected in the groove.
[0012] The effect achieved by the above-mentioned components is as follows: by utilizing the first spring, the impact force acting on the rotating shaft can compress the first spring during the impact process, thereby achieving the effect of mutual cancellation of the impact force on the rotating shaft, and thus improving the impact resistance of the rotating shaft inside the cylinder.
[0013] Preferably, a rotating ring is provided inside the cylinder, and a plurality of wedge blocks are slidably disposed within the rotating ring along the radial direction. The two ends of the second spring are respectively fixedly connected to the rotating ring and the wedge blocks.
[0014] The effect achieved by the above-mentioned components is as follows: by using wedge blocks, when the rotating shaft is subjected to impact force, the rotating shaft vibrates and can abut against the wedge blocks, so that the wedge blocks can slide along the wedge grooves opened on the circumference of the rotating shaft. In this way, the wedge blocks can compress the second spring during the sliding process, so that the vibration force generated by the vibration of the rotating shaft can abut against the compression force of the second spring, thereby improving the vibration reduction effect of the rotating shaft inside the cylinder, and further improving the impact resistance of the rotating shaft.
[0015] Preferably, a telescopic rod is fixedly installed inside the rotating ring, the output end of the telescopic rod is fixedly connected to the wedge block, and the second spring is sleeved on the telescopic rod.
[0016] The effect achieved by the above-mentioned components is that by using the telescopic rod, the second spring can be limited, thereby improving the stability of the wedge block during the sliding process.
[0017] Preferably, a buffer ring is rotatably provided on the other end face of the cylinder, the buffer ring being noise-reducing cotton, and the buffer ring is sleeved on the circumferential surface of the rotating shaft.
[0018] The aforementioned components achieve the following effects: by utilizing the buffer ring, they provide support for the rotating shaft; and by utilizing the noise-reducing cotton, they reduce noise in the rotating shaft inside the cylinder, thereby improving the practicality of the rotating shaft inside the cylinder.
[0019] Compared with the prior art, the beneficial effects of this utility model are: This invention utilizes a first spring to buffer the rotating shaft during impact, thus protecting it. Furthermore, a second spring transmits the vibrations generated by the rotating shaft during impact to wedge blocks, allowing multiple wedge blocks to dampen the vibrations of the rotating shaft during impact, further enhancing its impact resistance.
[0020] This invention utilizes a threaded rod and a threaded cylinder to facilitate the quick assembly and disassembly of the rotating shaft components inside the cylinder, thereby enabling the rapid replacement of these components and improving the overall practicality of the rotating shaft structure.
[0021] This invention utilizes a wedge-shaped block so that when the rotating shaft is subjected to impact, it vibrates and comes into contact with the wedge-shaped block, allowing the wedge-shaped block to slide along a wedge-shaped groove on the circumference of the rotating shaft. This sliding motion compresses the second spring, allowing the vibration force generated by the rotating shaft to counteract the compression force of the second spring. This improves the vibration damping effect of the rotating shaft inside the cylinder and further enhances its impact resistance.
[0022] This invention utilizes a buffer ring to support the rotating shaft, and noise-reducing cotton to reduce noise in the rotating shaft inside the cylinder, thereby improving the practicality of the rotating shaft inside the cylinder. Attached Figure Description

[0025] 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.
[0026] Please see Figure 1-4 This utility model provides a technical solution: an impact-resistant rotating shaft structure, including a cylindrical body 1, a rotating shaft 2 disposed inside the cylindrical body 1, a first spring 6 disposed between the rotating shaft 2 and the cylindrical body 1, and multiple wedge blocks 9 fixedly and radially slidably disposed inside the cylindrical body 1. A second spring 10 is disposed between each of the multiple wedge blocks 9 and the cylindrical body 1. Multiple wedge grooves 11 are formed on the circumferential surface of the rotating shaft 2 to cooperate with the wedge blocks 9. By utilizing the first spring 6, the rotating shaft 2 can be buffered during impact, thus providing protection. Furthermore, by utilizing the second springs 10, the vibration generated by the rotating shaft 2 during impact can be transmitted to the wedge blocks 9, thereby enabling the multiple wedge blocks 9 to dampen the vibration of the rotating shaft 2 during impact, further improving the impact resistance of the rotating shaft 2.
[0027] The following is a detailed explanation of its overall setup and function.
[0028] A threaded cylinder 3 is rotatably mounted on one end face of the cylinder body 1. A threaded rod 4 is threadedly connected inside the threaded cylinder 3, and the threaded rod 4 is coaxially connected to one end face of the rotating shaft component 2. By utilizing the threaded rod 4 and the threaded cylinder 3, the rotating shaft component 2 inside the cylinder body 1 can be easily and quickly disassembled and assembled, thereby facilitating the rapid replacement of the rotating shaft component 2 inside the cylinder body 1, thus improving the practicality of the entire rotating shaft structure.
[0029] A limiting plate 5 is fixedly installed on the circumferential surface of the threaded rod 4, and the limiting plate 5 movably abuts against the end face of the threaded cylinder 3. By using the limiting plate 5, the assembly position of the rotating shaft 2 can be restricted.
[0030] One end of the first spring 6 is fixedly connected to the end face of the threaded rod 4. A groove 7 is provided on the end face of the rotating shaft 2 near the threaded rod 4, and the other end of the first spring 6 is fixedly connected to the groove 7. By utilizing the first spring 6, the impact force acting on the rotating shaft 2 during the impact process can compress the first spring 6, thereby achieving the effect of mutual cancellation of the impact force on the rotating shaft 2, and thus improving the impact resistance of the rotating shaft 2 inside the cylinder 1.
[0031] A rotating ring 8 is rotatably arranged inside the cylinder 1, and multiple wedge blocks 9 are radially slidably arranged within the rotating ring 8. The two ends of the second spring 10 are respectively fixedly connected to the rotating ring 8 and the wedge blocks 9. By utilizing the wedge blocks 9, when the rotating shaft 2 is subjected to impact force, the rotating shaft 2 can abut against the wedge blocks 9 while vibrating. This allows the wedge blocks 9 to slide along the wedge grooves 11 opened on the circumference of the rotating shaft 2. During the sliding process, the wedge blocks 9 can compress the second spring 10, so that the vibration force generated by the vibration of the rotating shaft 2 can abut against the compression force of the second spring 10, thereby improving the vibration damping effect of the rotating shaft 2 inside the cylinder 1, and further improving the impact resistance of the rotating shaft 2.
[0032] A telescopic rod 12 is fixedly installed inside the rotating ring 8. The output end of the telescopic rod 12 is fixedly connected to the wedge block 9, and the second spring 10 is sleeved on the telescopic rod 12. By using the telescopic rod 12, the second spring 10 can be limited, thereby improving the stability of the wedge block 9 during the sliding process.
[0033] A buffer ring 13 is rotatably mounted on the other end face of the cylinder 1. The buffer ring 13 is made of noise-reducing cotton and is fitted onto the circumferential surface of the rotating shaft 2. By using the buffer ring 13, the rotating shaft 2 is supported, while by using the noise-reducing cotton, the noise of the rotating shaft 2 inside the cylinder 1 is reduced, thereby improving the practicality of the rotating shaft 2 inside the cylinder 1.
[0034] Working principle: By utilizing the threaded rod 4 and the threaded cylinder 3, the rotating shaft 2 inside the cylinder 1 can be quickly disassembled and assembled, thereby facilitating the quick replacement of the rotating shaft 2 inside the cylinder 1 and improving the practicality of the entire rotating shaft structure.
[0035] When the rotating shaft 2 inside the cylinder 1 is subjected to impact force, the first spring 6 buffers the rotating shaft 2 during the impact, thus protecting it. Furthermore, the second spring 10 transmits the vibration generated by the rotating shaft 2 to the wedge block 9 during the impact, thereby enabling multiple wedge blocks 9 to dampen the vibration of the rotating shaft 2 during the impact, further improving the impact resistance of the rotating shaft 2.
[0036] Furthermore, when the rotating shaft 2 inside the cylinder 1 is subjected to an impact force, the rotating shaft 2 will vibrate. At this time, by using the wedge block 9, the rotating shaft 2 can contact the wedge block 9 while vibrating during the impact force, so that the wedge block 9 can slide along the wedge groove 11 opened on the circumference of the rotating shaft 2. In this way, the wedge block 9 can compress the second spring 10 during the sliding process, so that the vibration force generated by the vibration of the rotating shaft 2 can be mutually resisted by the compression force of the second spring 10, thereby improving the vibration reduction effect of the rotating shaft 2 inside the cylinder 1, and further improving the impact resistance of the rotating shaft 2.
[0037] The use of buffer ring 13 provides support for the rotating shaft 2, while the use of noise-reducing cotton reduces noise in the rotating shaft 2 inside the cylinder 1, thereby improving the practicality of the rotating shaft 2 inside the cylinder 1.
