Description

Technical Field

[0001] The present invention relates to the technical field of water pipes, in particular to an anti-wear composite elastic water pipe. Background Art

[0002] In daily life and industrial production, water pipes are indispensable and important components, and are widely used in many scenarios such as household water supply, agricultural irrigation, construction, industrial fluid transportation, etc.

[0003] However, traditional water pipes often suffer from wear and tear during use due to friction and squeezing. This is particularly true in complex environments, such as outdoor work, industrial workshops, and agricultural irrigation, where wear and tear is particularly severe, significantly shortening their service life. Furthermore, traditional water pipes have poor elasticity and are prone to permanent deformation after bending or stretching, which in turn affects their effectiveness. Therefore, there is an urgent need for wear-resistant composite elastic water pipes to address these issues. Summary of the Invention

[0004] In response to the problems in the related art, the present invention proposes an anti-wear composite elastic water pipe to overcome the above-mentioned technical problems existing in the existing related art.

[0005] The technical solution of the present invention is achieved as follows: A wear-resistant composite elastic water pipe comprises an inner casing, the circumferential outer wall of the inner casing is provided with a wear-resistant sheath, and the circumferential outer wall of the wear-resistant sheath is provided with a wear-resistant component for improving the wear resistance of the water pipe; Both ends of the wear-resistant sheath are provided with threaded grooves for easy docking and installation of water pipes; The circumferential outer wall of the inner sleeve and the circumferential inner wall of the wear-resistant sleeve enclose a support cavity, and an elastic component for improving the elastic performance of the water pipe is arranged inside the support cavity; The elastic component includes a second spring and an elastic strip wound around the circumferential outer wall of the inner sleeve, and the second spring and the elastic strip are wound around the circumferential outer wall of the inner sleeve in a staggered manner; A support assembly for improving the pressure resistance of the water pipe is arranged inside the support cavity.

[0006] Preferably, the second spring and the elastic strip are both spirally wound on the circumferential outer wall of the inner sleeve, and the winding density of the second spring and the elastic strip at the end of the inner sleeve is greater than the winding density in the middle area of ​​the inner sleeve.

[0007] Preferably, the elastic strip includes an upper ring portion, an arc portion, a stress node portion, and a lower ring portion. The cross-section of the elastic strip is in the shape of a Chinese character 'Wang'. The stress node portion is located in the middle of the upper ring portion and the lower ring portion. The cross-sections of the upper ring portion and the lower ring portion are arc-shaped. The arc portion is arranged between the upper ring portion and the stress node portion or between the lower ring portion and the stress node portion. The arc portion is concave. Through holes are arranged in the elastic strip at equidistant intervals.

[0008] Preferably, the support assembly includes a support ring plate arranged inside the support cavity. The number of the support ring plates is four. The four support ring plates are stacked on top of each other to form a circular ring. The circumferential inner wall of the support ring plate is closely attached to the circumferential outer wall of the inner sleeve. The circumferential outer wall of the support ring plate is in contact with the circumferential inner wall of the wear-resistant sheath.

[0009] Preferably, extension ring plates and assembly grooves are respectively arranged at both ends of the support ring plate. The extension ring plate of one support ring plate is stacked with the assembly groove of another support ring plate. A matching component for ensuring the stable stacking of the two support ring plates is arranged on one side of each of the extension ring plate and the assembly groove.

[0010] Preferably, the matching component includes a matching groove opened on one side of the extension ring plate. The cross-section of the matching groove is in the shape of a wave. The matching groove includes wave crests and wave troughs. The matching grooves on the extension ring plate and the assembly groove are engaged with each other. The specification of the wave crest is smaller than that of the wave trough.

[0011] Preferably, circular ring ribs are fixedly connected to the circumferential outer wall of the support ring plate and are distributed in an equidistant circular shape. Radial spokes are arranged on the circumferential outer wall of the circular ring ribs. The spokes are pressed against the circumferential inner wall of the wear-resistant sheath.

[0012] Preferably, mounting holes are respectively opened on one side of the extension ring plate and the assembly groove. A first spring is fixedly connected inside the mounting hole. One support ring plate is fixedly connected to another support ring plate through the first spring.

[0013] Preferably, the wear-resistant component includes rubber strips and wear-resistant balls which are arranged on the circumferential outer wall of the wear-resistant sheath in an equidistant circular distribution. Two rubber strips are in the shape of a Chinese character 'Ren'. The wear-resistant balls are fixedly connected to the ends of the two rubber strips.

[0014] Preferably, the rubber strip includes a front end portion, a middle portion, and a rear end portion. The middle portion is arranged between the front end portion and the rear end portion. The front end portion is fixedly connected to the wear-resistant ball. The rear end portion is fixedly connected to the circumferential outer wall of the wear-resistant sheath. The diameters of the front end portion and the rear end portion are larger than that of the middle portion.

[0015] The beneficial effects of the present invention: The present invention provides an anti-wear composite elastic water pipe, which is provided with an elastic component. The elastic component is composed of a second spring and an elastic strip wound in a spiral staggered manner, which can make the water pipe have both the elasticity of the second spring and the flexibility of the elastic strip. The spiral winding is highly adapted to the cylindrical structure of the water pipe, and can evenly wrap the circumferential outer wall of the inner sleeve to make the force more balanced. When the water pipe is in use, the threaded grooves at both ends of the wear-resistant sheath are connected to the water supply pipeline. Since the pressure of the water flow in the pipeline has the characteristic of attenuating from the two ends to the middle section, the two ends of the inner sleeve are affected. The water pressure is greater than that in the middle area. At this time, the winding density of the second spring and the elastic strip at the end of the inner sleeve in the wear-resistant sheath is greater than that in the middle area of ​​the inner sleeve, so that the second spring and the elastic strip form a winding state of dense winding at both ends and sparse winding in the middle on the outer wall of the inner sleeve. At this time, the denser winding at the end of the water pipe can provide stronger elastic support, reduce the deformation of the connection, and effectively extend the service life of the entire water pipe. At the same time, the spacing in the middle part of the water pipe is slightly sparse, which can make the water pipe as a whole lighter and more flexible while ensuring a certain elastic force, and save more effort when bending; When the pipe is subjected to vibration or pressure during installation or use, the second spring acts as a buffer and protection. Subsequently, when the pressure is transmitted to the elastic strip, the elastic strip has a V-shaped cross section, which forms a stable upper and lower support and middle reinforcement structure through the upper and lower ring parts and the stress node in the middle, thereby improving the structural strength of the entire elastic strip and effectively resisting the impact force during deformation. Since the cross-sections of the upper and lower ring parts are arc-shaped, they can better adapt to the bending movement of the water pipe, reduce local stress concentration during bending, make the elastic strip smoother when bending with the water pipe, and reduce the risk of breakage. The arc-shaped part is concave, which provides a buffer space for elastic deformation of the elastic strip. When subjected to tension or compression, the elastic recovery ability can be enhanced through the expansion and contraction of the concave structure, thereby improving the flexibility of the elastic strip. The stress node in the middle further strengthens the deformation resistance of the elastic strip, avoids the occurrence of breakage in the middle of the elastic strip during repeated deformation, and extends the service life. The equidistant through holes arranged inside the elastic strip can provide more compression and extension space when subjected to stress deformation, making the elastic strip more elastic, while also reducing the weight of the elastic strip, making the entire water pipe lighter.

[0016] The present invention provides an anti-wear composite elastic water pipe. The support assembly is provided, which can not only significantly improve the pressure resistance of the water pipe, but also effectively disperse the concentrated stress when the middle section of the water pipe is squeezed or bent by external force, thereby avoiding excessive local deformation. The water pipe is composed of four support ring plates that are overlapped with each other in a circular shape. The inner wall of the circumference of the support ring plate is close to the inner sleeve, and the outer wall is in contact with the wear-resistant sleeve, forming a stable support structure, which can evenly disperse the external pressure and reduce the risk of deformation of the water pipe due to pressure. The extended ring plates at both ends of the support ring plate and the assembly groove are engaged with each other through wave-shaped matching grooves. The peak specification is smaller than the trough specification, which not only ensures the stability of the overlap but also allows a certain degree of relative movement, so that the support assembly can adaptively adjust with the deformation of the water pipe, avoiding the rigid support from restricting the elastic activity of the water pipe. The wave-shaped matching groove increases the contact area between the support ring plates, thereby improving the efficiency of stress transmission. The extended ring plate and the assembly groove are connected by a first spring. The elasticity of the spring can buffer the external impact force, further enhancing the pressure resistance while improving the flexibility of the support assembly. When the support ring plate of the support assembly is subjected to stress such as external pressure or internal water pressure tension, the stress is not limited to the vicinity of the stress point, but will be transmitted along the radially distributed spokes on the circular ribs, and diffuse from the stress-bearing local area to the entire annular structure of the support ring plate. This diffusion method can disperse the concentrated stress to a larger area, avoiding excessive stress accumulation in a certain area, which may cause deformation, cracking and other problems in the support ring plate, thereby enhancing the structural stability and damage resistance of the support assembly, and thus improving the pressure resistance and service life of the entire water pipe.

[0017] The present invention provides an anti-wear composite elastic water pipe. Through the wear-resistant components, when the worker pulls the water pipe to lay or shift it, the wear-resistant balls arranged on the outside of the wear-resistant sheath serve as the first line of defense and first contact the ground to directly withstand friction, thereby reducing direct wear between the wear-resistant sheath and the ground, and effectively extending the service life of the water pipe body. At the same time, the two rubber strips fixedly connected to the wear-resistant balls are in a herringbone shape. During the process of moving the water pipe, debris on the ground can slide along the inclination angle of the herringbone shape, reducing the risk of jamming. At the same time, the herringbone shape disperses the friction force on the wear-resistant balls, avoiding jamming caused by local stress concentration. The diameters of the front and rear ends of the rubber strip are larger than those of the middle part, thereby enhancing the connection strength with the wear-resistant ball and the wear-resistant sleeve, and avoiding the situation where the rubber strip breaks and the wear-resistant ball falls off. The middle part of the rubber strip is thinner, which can give the rubber strip a certain elasticity. When the wear-resistant ball encounters an impact, the middle part can slightly deform and cushion, reducing the vibration impact on the wear-resistant sleeve and avoiding secondary damage.

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention are within the scope of protection of the present invention.

[0032] See also Figures 1-11 A wear-resistant composite elastic water pipe comprises an inner casing 2, a wear-resistant sheath 1 is provided on the circumferential outer wall of the inner casing 2, and a wear-resistant component 4 for improving the wear resistance of the water pipe is provided on the circumferential outer wall of the wear-resistant sheath 1; Both ends of the wear-resistant sheath 1 are provided with threaded grooves 3 for easy docking and installation of water pipes; The outer circumferential wall of the inner sleeve 2 and the inner circumferential wall of the wear-resistant sheath 1 enclose a support cavity 8, and an elastic component for improving the elastic performance of the water pipe is arranged inside the support cavity 8; The elastic component includes a second spring 6 and an elastic strip 7 wound around the outer circumference of the inner sleeve 2. The second spring 6 and the elastic strip 7 are staggered around the outer circumference of the inner sleeve 2. The second spring 6 and the elastic strip 7 are staggered around the outer circumference of the inner sleeve 2. The second spring 6 and the elastic strip 7 are staggered around the inner circumference of the inner sleeve 2. The water pipe has both the elasticity of the second spring 6 and the flexibility of the elastic strip 7. The spiral winding is highly compatible with the cylindrical structure of the water pipe and can evenly wrap the outer circumference of the inner sleeve 2 to make the force more balanced. A support assembly 5 for improving the pressure resistance of the water pipe is provided inside the support cavity 8 .

[0033] Furthermore, both the second spring 6 and the elastic strip 7 are spirally wound around the circumferential outer wall of the inner sleeve 2. The winding density of the second spring 6 and the elastic strip 7 at the ends of the inner sleeve 2 is greater than that in the middle region of the inner sleeve 2. Since the water pressure in the pipeline has the characteristic of attenuating from both ends to the middle section, the water pressure received at both ends of the inner sleeve 2 is greater than that in the middle region. At this time, inside the wear-resistant sheath 1, the winding density of the second spring 6 and the elastic strip 7 at the ends of the inner sleeve 2 is greater than that in the middle region of the inner sleeve 2, so that the second spring 6 and the elastic strip 7 form a winding state with a dense middle and a sparse middle on the outer wall of the inner sleeve 2. At this time, the relatively dense winding at the ends of the water pipe can provide stronger elastic support, reduce the deformation at the connection, and effectively extend the service life of the entire water pipe. At the same time, the spacing in the middle part of the water pipe is slightly sparse, which can make the whole water pipe lighter, more flexible and easier to bend while ensuring a certain elastic force.

[0034] Furthermore, the elastic strip 7 includes an upper ring portion 701, an arc portion 702, a stress section portion 703 and a lower ring portion 704. The cross-section of the elastic strip 7 is in the shape of a king character. The stress section portion 703 is located in the middle of the upper ring portion 701 and the lower ring portion 704. The cross-sections of the upper ring portion 701 and the lower ring portion 704 are arc-shaped. The arc portion 702 is arranged between the upper ring portion 701 and the stress section portion 703 or between the lower ring portion 704 and the stress section portion 703. The arc portion 702 is concave. The elastic strip 7 is provided with through holes 705 distributed at equal distances inside. Since the cross-sections of the upper ring portion 701 and the lower ring portion 704 are arc-shaped, it can better adapt to the bending movement of the water pipe, reduce the local stress concentration during bending, make the elastic strip 7 smoother when bending with the water pipe, and reduce the risk of fracture. The concave arc portion 702 can provide a buffer space for the elastic deformation of the elastic strip 7. When being stretched or compressed, the elastic recovery ability can be enhanced through the expansion and contraction of the concave structure, improving the flexibility of the elastic strip 7. The stress section portion 703 located in the middle of the elastic strip 7 further strengthens the anti-deformation ability of the elastic strip 7, avoiding the fracture of the middle of the elastic strip 7 during repeated deformation and extending the service life. The equally spaced through holes 705 provided inside the elastic strip 7 can provide more compression and expansion space during deformation, making the elastic strip 7 more elastic, and at the same time can also reduce the weight of the elastic strip 7, making the whole water pipe lighter.

[0035] Furthermore, the support assembly 5 includes a support ring plate 501 arranged inside the support cavity 8. The number of the support ring plates 501 is four. The four support ring plates 501 overlap each other to form a circular ring. The circumferential inner wall of the support ring plate 501 is tightly attached to the circumferential outer wall of the inner sleeve 2. The circumferential outer wall of the support ring plate 501 contacts the circumferential inner wall of the wear-resistant sleeve 1. The two ends of the support ring plate 501 are respectively provided with an extension ring plate 50103 and an assembly groove 50104. The extended ring plate 50103 of the support ring plate 501 overlaps with the assembly groove 50104 of another support ring plate 501. One side of the extended ring plate 50103 and the assembly groove 50104 are both provided with matching components to ensure that the two support ring plates 501 are stably overlapped. The circumferential inner wall of the support ring plate 501 is close to the inner sleeve 2, and the outer wall is in contact with the wear-resistant sleeve 1, forming a stable support structure, which can evenly disperse the external pressure and reduce the risk of deformation of the water pipe due to pressure.

[0036] Furthermore, the mating component includes a mating groove opened on one side of the extended ring plate 50103, the cross-section of the mating groove is wavy, and the mating groove includes a crest 50101 and a trough 50102. The mating grooves on the extended ring plate 50103 and the assembly groove 50104 are engaged with each other, and the specifications of the crest 50101 are smaller than the specifications of the trough 50102, and the specifications of the crest 50101 are smaller than the specifications of the trough 50102. This not only ensures the stability of the superposition, but also allows a certain degree of relative movement, so that the support component 5 can adaptively adjust with the deformation of the water pipe, avoiding rigid support limiting the elastic activity of the water pipe, and the wavy mating groove increases the contact area between the support ring plates 501, thereby improving the efficiency of stress transfer.

[0037] Furthermore, the circumferential outer wall of the support ring plate 501 is fixedly connected with annular ribs 502 that are distributed in an annular pattern at equal distances, and the circumferential outer wall of the annular rib 502 is provided with radially distributed spokes 503, which are pressed against the circumferential inner wall of the wear-resistant sleeve 1. When the support ring plate 501 of the support assembly 5 is subjected to stress such as external pressure or internal water pressure tension, the stress is not limited to the vicinity of the stress point, but will be transmitted along the radially distributed spokes 503 on the annular rib 502, and diffused from the stress-bearing local area to the entire annular structure of the support ring plate 501. This diffusion method can disperse the concentrated stress to a larger area, avoiding excessive stress accumulation in a certain area, which may cause deformation, cracking and other problems in the support ring plate 501, thereby enhancing the structural stability and damage resistance of the support assembly 5, and thus improving the pressure resistance and service life of the entire water pipe.

[0038] Furthermore, a mounting hole 505 is provided on one side of the extension ring plate 50103 and the assembly groove 50104, and a first spring 504 is fixedly connected to the inside of the mounting hole 505. One support ring plate 501 is fixedly connected to another support ring plate 501 through the first spring 504. The elasticity of the first spring 504 can buffer external impact force, further enhance the compressive resistance, and improve the flexibility of the support assembly 5.

[0039] Furthermore, the wear-resistant component 4 includes rubber strips 402 and wear-resistant balls 401 that are arranged on the outer wall of the wear-resistant sleeve 1 in an equidistant circular distribution. The two rubber strips 402 are in a herringbone shape, and the wear-resistant balls 401 are fixedly connected to the ends of the two rubber strips 402. The wear-resistant balls 401 arranged on the outside of the wear-resistant sleeve 1 serve as the first line of defense and directly contact the ground to withstand friction, thereby reducing the direct wear between the wear-resistant sleeve 1 and the ground, and effectively extending the service life of the water pipe body. At the same time, the two rubber strips 402 fixedly connected to the wear-resistant balls 401 are in a herringbone shape. During the movement of the water pipe, debris on the ground can slide along the inclination angle of the herringbone, reducing the risk of jamming. At the same time, the herringbone shape disperses the friction force on the wear-resistant balls 401, avoiding jamming caused by local stress concentration.

[0040] Furthermore, the rubber strip 402 includes a front end portion 40201, a middle portion 40202, and a rear end portion 40203. The middle portion 40202 is arranged between the front end portion 40201 and the rear end portion 40203. The front end portion 40201 is fixedly connected to the wear-resistant ball 401, and the rear end portion 40203 is fixedly connected to the circumferential outer wall of the wear-resistant sleeve 1. The diameters of the front end portion 40201 and the rear end portion 40203 are larger than the diameter of the middle portion 40202, thereby enhancing the connection strength with the wear-resistant ball 401 and the wear-resistant sleeve 1, and avoiding the situation where the rubber strip 402 is easily broken and the wear-resistant ball 401 falls off. The middle portion 40202 of the rubber strip 402 is thinner, thereby giving the rubber strip 402 a certain elasticity. When the wear-resistant ball 401 encounters an impact, the middle portion 40202 can be slightly deformed and buffered, reducing the vibration impact on the wear-resistant sleeve 1 and avoiding secondary damage.

[0041] In summary, by means of the above technical solution of the present invention, the elastic components in the entire water pipe are composed of the second spring 6 and the elastic strip 7 wound in a spiral and staggered manner, enabling the water pipe to have both the elasticity of the second spring 6 and the flexibility of the elastic strip 7. Moreover, the spiral winding is highly adaptable to the cylindrical structure of the water pipe, and can evenly wrap the outer circumferential wall of the inner sleeve 2 to make the force more balanced. When the water pipe is in use, it is connected to the water conveyance pipeline through the threaded grooves 3 at both ends of the wear-resistant sheath 1. Since the water pressure in the pipeline has the characteristic of attenuating from both ends to the middle section, the water pressure received at both ends of the inner sleeve 2 is greater than that in the middle region. At this time, inside the wear-resistant sheath 1, the winding density of the second spring 6 and the elastic strip 7 at the ends of the inner sleeve 2 is greater than that in the middle region of the inner sleeve 2, so that the second spring 6 and the elastic strip 7 form a winding state with a dense ends and a sparse middle on the outer wall of the inner sleeve 2. At this time, the denser winding at the ends of the water pipe can provide stronger elastic support, reduce the deformation at the connection, and effectively extend the service life of the entire water pipe. At the same time, the spacing in the middle part of the water pipe is slightly sparser, which can make the whole water pipe lighter, more flexible and easier to bend while ensuring a certain elastic force; Moreover, when the water pipe is subjected to vibration or pressure during the laying process or use, the second spring 6 plays a role of primary buffer protection. Subsequently, when the pressure is transmitted into the elastic strip 7, since the cross-section of the elastic strip 7 is in a king shape, a stable upper and lower support and a middle strengthening structure are formed through the upper ring part 701, the lower ring part 704 and the middle stress section part 703 inside it, thereby enhancing the structural strength of the entire elastic strip 7 and effectively resisting the impact force during deformation; Since the cross-sections of the upper ring part 701 and the lower ring part 704 are in an arc shape, it can better adapt to the bending movement of the water pipe, reduce the local stress concentration during bending, make the elastic strip 7 smoother when bending along with the water pipe, and reduce the risk of fracture. The arc part 702 is concave, which can provide a buffer space for the elastic deformation of the elastic strip 7. When being stretched or compressed by force, the elastic recovery ability can be enhanced through the stretching and contraction of the concave structure, and the flexibility of the elastic strip 7 is improved. The stress section part 703 located in the middle part 40202 further strengthens the anti-deformation ability of the elastic strip 7, avoids the fracture of the middle part 40202 during repeated deformation, and extends the service life. The equidistant through holes 705 arranged inside the elastic strip 7 can provide more compression and stretching space during deformation, make the elasticity of the elastic strip 7 better, and at the same time can reduce the weight of the elastic strip 7, making the entire water pipe lighter; The support assembly 5 arranged inside the support cavity 8 can be arranged at equal distances according to the length of the water pipe. The support assembly 5 can not only significantly improve the pressure resistance of the water pipe, but also when the middle section of the water pipe is squeezed or bent by external force, the support assembly 5 can effectively disperse the concentrated stress to avoid excessive local deformation. It is composed of four mutually overlapping support ring plates 501 in a circular shape. The inner wall of the circumference of the support ring plate 501 is close to the inner sleeve 2, and the outer wall is in contact with the wear-resistant sheath 1 to form a stable support structure, which can evenly disperse the external pressure and reduce the risk of deformation of the water pipe due to pressure. The extended ring plates 50103 at both ends of the support ring plate 501 are connected to the assembly groove 501. 04 are engaged with each other through the wavy assembly groove 50104, and the specifications of the wave crest 50101 are smaller than those of the wave trough 50102, which not only ensures the stability of the superposition, but also allows a certain degree of relative movement, so that the support assembly 5 can adaptively adjust with the deformation of the water pipe, avoiding the rigid support restricting the elastic activity of the water pipe. In addition, the wavy assembly groove 50104 increases the contact area between the support ring plates 501, thereby improving the efficiency of stress transmission. The extension ring plate 50103 and the assembly groove 50104 are connected by the first spring 504. The elasticity of the spring can buffer external impact force, further enhancing the pressure resistance while improving the flexibility of the support assembly 5; When the support ring plate 501 of the support assembly 5 is subjected to stress such as external pressure or internal water pressure tension, the stress is not confined to the vicinity of the stress point, but is transmitted along the radially distributed spokes 503 on the annular ribs 502, and diffuses from the stress-bearing local area to the entire annular structure of the support ring plate 501. This diffusion method can disperse the concentrated stress to a larger area, avoiding excessive stress accumulation in a certain area, which may cause deformation, cracking, and other problems in the support ring plate 501, thereby enhancing the structural stability and damage resistance of the support assembly 5, and further improving the pressure resistance and service life of the entire water pipe. When the staff pulls the water pipe to lay or shift it, the wear-resistant balls 401 arranged on the outside of the wear-resistant sheath 1 serve as the first line of defense and first contact the ground to directly withstand friction, thereby reducing the direct wear between the wear-resistant sheath 1 and the ground, and effectively extending the service life of the water pipe body. At the same time, the two rubber strips 402 fixedly connected to the wear-resistant balls 401 are in a herringbone shape. During the process of moving the water pipe, debris on the ground can slide along the inclination angle of the herringbone shape, reducing the risk of jamming. At the same time, the herringbone shape disperses the friction force on the wear-resistant balls 401, avoiding jamming caused by local stress concentration. The diameters of the front end 40201 and the rear end 40203 of the rubber strip 402 are both larger than the middle part 40202, thereby enhancing the connection strength with the wear-resistant ball 401 and the wear-resistant sleeve 1, and avoiding the situation where the rubber strip 402 breaks and the wear-resistant ball 401 falls off. The middle part 40202 of the rubber strip 402 is thinner, thereby giving the rubber strip 402 a certain elasticity. When the wear-resistant ball 401 encounters an impact, the middle part 40202 can be slightly deformed to provide a buffer, reducing the vibration impact on the wear-resistant sleeve 1 and avoiding secondary damage.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
