Description

Technical Field

[0001] This invention relates to the field of floating ball valve technology, specifically to a quick-opening float level controller based on a spring-jump mechanism. Background Technology

[0002] The floating ball valve is a key component widely used in automatic liquid level control devices such as water towers, pools, and tanks. Its basic principle is to use the buoyancy change generated by the floating ball as the liquid level rises and falls, and drive the valve core to move through the lever mechanism, thereby realizing the opening or closing of the water inlet.

[0003] In traditional floating ball valves, as the liquid level drops, the float descends accordingly, and the valve core gradually opens, with the inlet flow rate increasing slowly as the valve opening widens. While this gradual opening method is structurally simple and reliable, it reveals a significant problem in practical applications: Initially, when the floating ball valve switches from a closed to an open state, the valve opening is extremely small, while the pressure difference between the inlet and outlet is large. This causes water to rush through the narrow valve opening at extremely high speeds, resulting in severe scouring and erosion of the valve disc (or sealing element) sealing surface. Over long-term, repeated action, the valve disc surface material is prone to wear, deformation, and even peeling, ultimately leading to poor valve sealing, leakage, or failure, severely impacting the service life and reliability of the floating ball valve.

[0004] To improve valve opening performance, some technologies have attempted to add counterweights or auxiliary springs to floating ball valves to help the valve core overcome water pressure and operate quickly. For example, Chinese utility model patent application CN221610720U, entitled "A Floating Ball Valve," discloses a floating ball valve that uses a lever principle to allow a sealing element to move vertically when the water level changes by setting a floating ball and a counterweight at both ends of a connecting rod, thereby adjusting the flow channel size. This solution reduces the resistance of water pressure to valve opening to a certain extent, making the valve easier to open.

[0005] However, the opening process of the floating ball valve in this utility model patent is still continuous and slow, changing with the water level—the sealing element moves gradually as the floating ball rises, and the valve opening gradually increases from zero. This does not change the problem of the long-term high-speed scouring of the valve plate by the water flow during the low-speed opening process. In other words, even if the opening force is reduced, the valve plate still needs to withstand the impact of the high-speed water flow in the initial opening stage, and the wear problem still exists.

[0006] Therefore, how to achieve rapid opening of floating ball valves and shorten the exposure time of valve plates under water flow scouring, thereby reducing wear and extending valve life, is a technical problem that urgently needs to be solved in this field.

[0007] To address this, a quick-opening float level controller based on a spring-jump mechanism is proposed. Summary of the Invention

[0008] The purpose of this invention is to provide a quick-opening float level controller based on a spring-jump mechanism, which achieves instantaneous valve opening through spring-jump action, avoiding continuous scouring of the valve plate by high-speed water flow when it is partially open, thereby solving the problems mentioned in the background art.

[0009] To achieve the above objectives, the present invention provides the following technical solution: A quick-opening float level controller based on a spring-loaded mechanism includes a valve body with an inlet and an outlet. A valve stem is vertically slidably mounted on the valve body, and a valve plate at the lower end of the valve stem for connecting or disconnecting the inlet and outlet is provided. A spring cavity is provided on the valve body, and the top of the valve stem passes through and extends out of the spring cavity. A push spring is provided inside the spring cavity to keep the valve stem pushed upward. A locking groove is horizontally provided at the top of the spring cavity, and a locking block is horizontally slidably mounted inside the locking groove. A locking spring is provided inside the locking groove to keep the locking block pushed horizontally towards the valve stem. A locking platform is provided on the valve stem to cooperate with the locking block. The valve body is provided with... The device includes a rotating frame on which a swing arm is rotatably mounted. One end of the swing arm facing the valve stem is the pressing end, and the other end is the detection end. The point where the rotating frame connects to the swing arm is the rotation point. A connecting rod is fixedly mounted below the detection end, and a floating ball for detecting water level is fixedly mounted at the bottom of the connecting rod. A limit groove is horizontally provided on the rotating frame, and an unlocking groove is provided on the valve stem, which horizontally penetrates the valve stem. When the top surface of the clamping platform is in contact with the bottom of the clamping block, the limit groove, the unlocking groove, and the clamping block are aligned with each other. An elastic rod is fixedly mounted below the swing arm, and the connection point between the elastic rod and the swing arm is located between the detection end and the rotation point. The free end of the elastic rod passes around the bottom of the rotation point and through the limit groove, horizontally facing the clamping block.

[0010] By setting a locking block and a pushing spring, when the bottom surface of the locking block is in contact with the top surface of the locking platform, the locking block blocks the valve stem from moving upward, the pushing spring is in a compressed state, the valve plate isolates the inlet and outlet, and the valve is closed.

[0011] As the water level drops, the floating ball pulls the pendulum rod to rotate under gravity. The detection end of the pendulum rod rotates downwards around the rotation point, thus squeezing the elastic rod and causing its free end to move horizontally towards the valve stem along the limiting groove. As the water level continues to drop, the free end of the elastic rod eventually inserts into the unlocking groove and pushes the locking block into the locking groove. When the bottom surface of the locking block disengages from the top surface of the locking platform, the elastic rod's own rigidity is insufficient to press the valve stem downwards. The compressed push spring, under its own elastic force, instantly pushes the valve stem upwards, and the valve plate moves upwards rapidly. The inlet and outlet are instantly connected, and the valve opens quickly. During the upward movement of the valve stem, the elastic rod undergoes elastic deformation under the compression of the valve stem to avoid impact, ensuring the valve stem moves upwards smoothly. Because the valve unlocks instantly under the action of the push spring, the valve plate is prevented from being subjected to the scouring of high-speed water flow for a long time in a partially open state, thus significantly improving the service life of the valve plate.

[0012] After the valve is opened, as the water level gradually rises, the float ball moves upward, causing the detection end of the lever to rotate upward around the pivot point. At this time, the free end of the elastic rod is pulled back towards the detection end, while the pressing end of the lever rotates downward and contacts the top of the valve stem, pressing the valve stem and valve plate downward. This gradually compresses the spring, and the valve plate slowly closes the valve. When the locking platform on the valve stem falls back below the locking block, the locking block pops out under the push of the locking spring, re-locking the locking platform, preventing the valve stem from moving upward under the action of the spring, and the valve returns to the closed state.

[0013] Preferably, the swing arm has a sliding groove inside, and an impact block is slidably installed inside the sliding groove. An impact head is provided at the end of the impact block facing the pressing end. The top of the valve stem is provided with an inclined chamfer facing the swing arm. When the impact block moves to the limit position of the pressing end, the impact head extends out of the sliding groove.

[0014] By setting up a chute and an impact block, when the water level rises and causes the detection end of the swing arm to rotate upward, the entire swing arm deflects around the rotation point as its axis, and the chute tilts synchronously. The impact block, which was originally stationary on the side of the chute near the detection end, slides along the chute towards the pressing end. When the swing arm rotates to a preset angle close to the valve, the impact block slides to the limit position of the pressing end, the impact head extends out of the chute and impacts the top of the valve stem. With the impact force of the impact block, the valve stem is driven to move downward quickly, which allows the valve plate to quickly block the water inlet, realize the rapid closure of the valve, avoid the overflow caused by the water level being too high due to the slow valve closing process, and at the same time reduce the long-term scouring of the sealing surface by the water flow during the closing process, further improving the sealing performance and service life.

[0015] In addition, as the valve plate gradually closes the valve, the water pressure on the valve plate increases, which increases the friction of the valve plate and valve stem moving downward, making it more difficult to close the valve. The impact of the impact block can ensure that the valve can close stably, thus ensuring the stability of the equipment.

[0016] Preferably, a slot is provided at the bottom of the slide groove near the detection end. A limiting plate is rotatably installed in the slot near the pressing end. A torsion spring is provided on the limiting plate to keep the limiting plate deflecting upward. When the limiting plate deflects downward around the rotating mounting point towards the detection end until it is parallel to the slide groove, the limiting plate is completely housed in the slot. A pull rope is provided at the bottom of the limiting plate. A horizontal plate is provided on the side of the valve body facing the detection end. A blocking groove is provided on the horizontal plate. One end of the pull rope is fixedly connected to the bottom of the limiting plate, and the other end passes through the blocking groove and extends below the horizontal plate. A blocking plate is provided on the part of the pull rope below the horizontal plate, and the blocking plate cannot pass through the blocking groove.

[0017] By setting a limit plate and a pull rope, when the water level drops, the impact block slides towards the detection end. Under its own weight, the impact block squeezes the limit plate, which can squeeze the limit plate into the slot, allowing the impact block to pass through the limit plate smoothly. After the impact block passes through the limit plate, the torsion spring drives the limit plate to reset, preventing the impact block from moving towards the pressing end.

[0018] As the water level gradually rises, when the upward rotation of the pendulum's detection end is small, the pull rope loosens, and the limiting plate, under the action of the torsion spring, deflects upward and extends out of the slot, blocking the impact block and causing it to remain on the side of the slide near the detection end to store energy. As the upward rotation angle of the pendulum's detection end gradually increases, the pull rope is gradually tightened. When the pendulum rotates to the preset trigger angle, the pull rope pulls the limiting plate, causing it to deflect downward against the torsion spring force until it is completely retracted into the slot. At this point, the obstruction to the impact block is released, and the impact block slides rapidly down the slide and impacts the valve stem, ensuring that the impact block obtains sufficient downward sliding distance and accumulates sufficient impact force to ensure that the valve stem is impacted to the closed position in one go, achieving instantaneous valve closure.

[0019] This is because as the water level rises, the valve is gradually closed by the pressing end of the rocker arm, the valve opening gradually decreases, and the water flow velocity increases, intensifying the scouring effect on the valve plate. If the impact block is not limited and slides downward in the initial stage of valve closure, the impact block may slide down only a short distance due to its small angle, slow speed, and insufficient impact force, failing to completely close the valve plate instantly. Instead, the valve plate is subjected to high-speed water flow scouring for a longer period at a smaller opening, accelerating wear. This solution uses a limiting plate to keep the impact block at a high position in the groove. The impact block is released only when the rocker arm rotates to near the critical closing angle, allowing it to push the valve rod to the closed position with sufficient speed and kinetic energy in one go. This minimizes the time the valve plate is subjected to scouring at a partial opening, significantly extending the valve plate's lifespan.

[0020] Preferably, rolling grooves are provided on both the left and right sides below the sliding groove, and multiple balls are arranged in an array inside each rolling groove, with the bottom surface of the impact block abutting against the apex of the balls.

[0021] By setting up grooves and balls, the sliding friction between the impact block and the chute is transformed into rolling friction, which effectively reduces the frictional resistance encountered by the impact block during sliding. This not only prevents the impact block from getting stuck in the chute due to excessive friction and being unable to slide down to the detection end to store energy, but also increases the acceleration of the impact block during its descent, further increasing the impact force when the impact block hits the valve stem, ensuring that the valve can be closed instantly.

[0022] Preferably, a connecting rod is horizontally fixedly installed on the side of the valve stem facing the rotating frame. The connecting rod extends horizontally towards the rotating frame, and a spring is provided on the top surface of the end of the connecting rod facing the rotating frame. The spring is arc-shaped, and the convex side of the arc-shaped spring faces upward.

[0023] By setting up a connecting rod and an arc-shaped spring, when the push spring causes the valve stem to spring upward, completing the rapid opening of the valve, the connecting rod moves upward synchronously with the valve stem. As the arc-shaped spring moves upward with the valve stem, it contacts the swing arm and applies an upward impact vibration to the swing arm, causing the swing arm to vibrate. This ensures that the impact block in the swing arm groove falls smoothly back to the energy storage position near the detection end of the groove, further preventing the impact block from getting stuck in the middle of the groove and failing to reset properly. This ensures that the impact block can obtain sufficient downward sliding distance and impact force when the next closing action is triggered, effectively improving the overall stability of the equipment operation.

[0024] Preferably, the pull rope is made of a loose and porous flexible material, the ball is made of hard plastic, the bottom end of the pull rope extends to the bottom of the floating ball and is fixedly connected to the bottom of the floating ball, and lubrication ports are provided on both the left and right sides of the slot, and the two lubrication ports are respectively connected to the two rolling grooves.

[0025] With the above structure, the pull rope is made of a loose, porous, flexible material, and its bottom end is fixed to the bottom of the floating ball, ensuring constant contact with the water surface. It utilizes capillary effect to continuously transport water to the slot area at the top of the pull rope. When the pull rope pulls the limiting plate downwards and retracts into the slot, the limiting plate squeezes the pull rope, squeezing out the water stored within it. The squeezed water flows into the roller groove through the lubrication ports on both sides of the slot, automatically lubricating the rollers and further reducing rotational friction, ensuring smooth sliding of the impact block.

[0026] Meanwhile, as the impact block slides towards the detection end, it pushes the limiting plate into the slot, which also squeezes out the water inside the pull rope, ensuring that the ball bearings are lubricated twice per cycle of the swing arm, further guaranteeing the operational stability of the equipment.

[0027] The ball bearings are made of hard plastic, which avoids the problem of metal ball bearings rusting and jamming after long-term contact with water. This effectively improves the reliability and service life of the mechanism, and eliminates the need for manual lubrication, thus reducing the maintenance cost of the equipment.

[0028] Preferably, the valve stem has an clearance groove that extends horizontally through the valve stem toward the rotating frame and is connected to the unlocking groove. The width of the clearance groove is greater than or equal to the width of the elastic rod.

[0029] By creating an clearance groove, when the free end of the elastic rod is inserted into the unlocking groove and pushes the locking block to unlock, the valve stem instantly springs upward. The elastic rod can bend upward and enter the clearance groove, preventing the elastic rod from getting stuck at the edge of the unlocking groove and hindering the upward movement of the valve stem. This ensures that the valve stem can be fully pushed up by the spring, ensuring that the valve is fully opened.

[0030] At the same time, it will not affect the normal push of the elastic rod to complete the unlocking action. While ensuring the normal realization of the original function of the mechanism, it further improves the reliability of valve opening and avoids the problem of insufficient valve opening due to the sticking of the elastic rod.

[0031] In addition, when the elastic rod is deformed by the upward movement of the valve stem, it can also vibrate the swing arm because the elastic rod is fixedly connected to the swing arm. This, together with the spring, achieves double vibration of the swing arm, further ensuring that the impact block can fall completely into place.

[0032] Preferably, the distance from the detection end to the rotation point is greater than the distance from the pressing end to the rotation point.

[0033] By designing the detection end as a long lever arm and the pressing end as a short lever arm, a small change in the buoyancy of the floating ball can generate a sufficiently large pressing force at the pressing end. This can easily overcome the resistance brought by the spring force and water pressure, ensuring that the valve stem is smoothly pressed down to complete the valve closing action. At the same time, it can also amplify the rotational displacement of the swing arm caused by water level changes, improve the sensitivity of water level detection, and ensure that the equipment can accurately respond to water level changes and perform valve opening and closing actions in a timely manner.

[0034] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The quick-opening float level controller based on a spring-jump mechanism designed in this invention, by setting a push spring, a locking spring, and a swing rod and elastic rod for unlocking and resetting, utilizes a spring-jump locking and unlocking structure to achieve instantaneous completion of valve opening action, avoiding the valve plate being subjected to high-speed water flow scouring at a partial opening for a long time, effectively improving the service life of the valve plate. At the same time, the switching action responds quickly and can accurately follow water level changes to complete control, resulting in higher water level control accuracy.

[0035] 2. By adding an energy storage impact structure with an impact block, and in conjunction with a one-way limit mechanism, when the water level rises to the critical closing position, the valve stem can be pushed to the closed position in one go by the instantaneous impact force of the impact block, thereby achieving instantaneous valve closure. This not only avoids water overflow, but also further reduces the time that the valve plate is eroded at a partial opening, extending its service life. At the same time, the impact force can overcome the valve closing resistance caused by increased water pressure, ensuring stable and reliable valve closing action.

[0036] 3. Through the capillary self-lubricating structure design, the rolling structure of the impact block can be automatically lubricated by the water on the water surface, while avoiding the corrosion of the balls. No manual maintenance is required, which reduces the cost of equipment use and maintenance and further improves the reliability of the mechanism operation. Attached Figure Description

A valve stem 4 is vertically slidably mounted on the valve body 1. A valve plate 5 for connecting or disconnecting the inlet 2 and the outlet 3 is provided at the lower end of the valve stem 4. A spring cavity 6 is provided on the valve body 1. The top of the valve stem 4 passes through the spring cavity 6 and extends out of the spring cavity 6.

[0040] refer to Figure 3 and Figure 4 A push spring 7 is provided inside the spring cavity 6. The push spring 7 is used to keep pushing the valve stem 4 upward. A locking groove 8 is horizontally provided at the top of the spring cavity 6. A locking block 9 is horizontally slidably installed inside the locking groove 8. A locking spring 10 is provided inside the locking groove 8. The locking spring 10 is used to keep pushing the locking block 9 horizontally towards the valve stem 4. A locking platform 11 is provided on the valve stem 4 to cooperate with the locking block 9.

[0041] refer to Figure 1 , Figure 3 as well as Figure 5A rotating frame 12 is provided on the valve body 1, and a rocker arm 13 is rotatably mounted on the rotating frame 12. One end of the rocker arm 13 facing the valve stem 4 is the pressing end 14, and the other end of the rocker arm 13 is the detection end 15. The position where the rotating frame 12 and the rocker arm 13 are connected is the rotation point 16. The distance from the detection end 15 to the rotation point 16 is greater than the distance from the pressing end 14 to the rotation point 16. A connecting rod 17 is fixedly installed below the detection end 15, and a float ball 18 for detecting the water level is fixedly installed at the bottom of the connecting rod 17.

[0042] refer to Figure 1 , Figure 5 , Figure 6 as well as Figure 7 The lever 13 has a groove 21 inside, and an impact block 22 is slidably installed inside the groove 21. An impact head 23 is provided at the end of the impact block 22 facing the pressing end 14. The top of the valve stem 4 is provided with an inclined chamfer 24 facing the lever 13. When the impact block 22 moves to the limit position of the pressing end 14, the impact head 23 extends out of the groove 21. Roller grooves 31 are provided on both the left and right sides below the groove 21. Multiple balls 32 are arranged in an array inside each roller groove 31. The balls 32 are made of hard plastic, and the bottom surface of the impact block 22 abuts against the apex of the balls 32.

[0043] refer to Figure 1 , Figure 5 , Figure 7 as well as Figure 8 A slot 25 is provided at the bottom of the slide groove 21 near the detection end 15, and lubrication ports 35 are provided on both the left and right sides of the slot 25. The two lubrication ports 35 are respectively connected to the two roller grooves 31. A limiting plate 26 is rotatably installed in the slot 25 near the pressing end 14. A torsion spring 27 is provided on the limiting plate 26 to keep the limiting plate 26 deflected upward. When the limiting plate 26 deflects downward around the rotatable mounting point towards the detection end 15 until it is parallel to the slide groove 21, the limiting plate 26 is completely housed in the slot 25. A pull rope 28 is also provided at the bottom of the limiting plate 26. The pull rope 28 is made of a loose and porous flexible material, such as a water-absorbing sponge, water-absorbing cotton core, or other flexible hydrophilic porous materials. In addition, a horizontal plate 29 is provided on the side of the valve body 1 facing the detection end 15. A blocking groove 30 is provided on the horizontal plate 29. One end of the pull rope 28 is fixedly connected to the bottom of the limiting plate 26, and the other end passes through the blocking groove 30 and extends to the bottom of the horizontal plate 29. A blocking plate 37 is fixedly attached to the part of the pull rope 28 below the horizontal plate 29. The blocking plate 37 is fixedly connected to the outer surface of the pull rope 28, and the area of ​​the blocking plate 37 is larger than the area of ​​the blocking groove 30, ensuring that the blocking plate 37 cannot pass through the blocking groove 30. At the same time, the bottom end of the pull rope 28 extends to the bottom of the float ball 18 and is fixedly connected to the bottom of the float ball 18, ensuring that the pull rope 28 is always in contact with water.

[0044] refer to Figure 1 , Figure 3 as well as Figure 4 The rotating frame 12 is also horizontally provided with a limiting groove 19, and the valve stem 4 is provided with an unlocking groove 38, which horizontally passes through the valve stem 4. When the top surface of the clamping platform 11 is in contact with the bottom of the clamping block 9, the limiting groove 19, the unlocking groove 38 and the clamping block 9 are aligned with each other. An elastic rod 20 is fixedly installed below the swing rod 13. The connection position between the elastic rod 20 and the swing rod 13 is located between the detection end 15 and the rotation point 16. The free end of the elastic rod 20 passes around the bottom of the rotation point 16 and passes through the limiting groove 19 horizontally toward the clamping block 9.

[0045] In addition, a clearance groove 36 is provided on the valve stem 4. The clearance groove 36 extends horizontally through the valve stem 4 in the direction of the rotating frame 12, and the clearance groove 36 is connected to the unlocking groove 38. The width of the clearance groove 36 is greater than or equal to the width of the elastic rod 20.

[0046] Further reference Figure 4 A lap rod 33 is also horizontally fixed on the side of the valve stem 4 facing the rotating frame 12. The lap rod 33 extends horizontally towards the rotating frame 12. A spring 34 is provided on the top surface of the end of the lap rod 33 facing the rotating frame 12. The spring 34 is arc-shaped, and the protruding side of the arc-shaped spring 34 faces upward.

[0047] When using, refer to Figures 1 to 8 As the water level drops, the floating ball 18 moves downward, causing the swing rod 13 to rotate downward around the rotation point 16. At the same time, the swing rod 13 squeezes the elastic rod 20. Guided by the limiting groove 19, the free end of the elastic rod 20 is inserted into the aligned unlocking groove 38, pushing the locking block 9 to overcome the elastic force of the locking spring 10 and slide into the locking groove 8.

[0048] When the water level reaches the minimum set value, refer to Figure 4 The elastic rod 20 pushes the locking block 9 to disengage from the locking platform 11. The valve stem 4 is compressed and pushed upward by the spring 7, which drives the valve plate 5 to move upward instantly, quickly and completely opening the passage between the inlet 2 and the outlet 3, realizing the instantaneous opening of the valve, and avoiding the valve plate 5 from being worn by high-speed water flow for a long time under partial opening.

[0049] During the upward movement of valve stem 4, refer to Figure 4 and Figure 5 The arc-shaped spring 34 moves upward synchronously with the valve stem 4. After contacting the rocker arm 13, it applies an upward impact vibration to the rocker arm 13. At the same time, the elastic rod 20 is driven by the upward-moving valve stem 4 to bend and enter the relief groove 36. During the deformation of the elastic rod 20, it also drives the rocker arm 13 to generate additional vibration. Under the action of dual vibration, the impact block 22 in the slide groove 21 of the rocker arm 13 is guaranteed to overcome the friction force smoothly and fall back to the energy storage position near the detection end 15 of the slide groove 21, preparing for the next valve closing action.

[0050] As the water level gradually rises, refer to Figures 5 to 8 The floating ball 18 rises upward, causing the swing arm 13 to gradually rotate. The pressing end 14 of the swing arm 13 gradually deflects downward and abuts against the top of the connecting rod 33 or the valve stem 4. The pressing end 14 presses the valve stem 4 downward. At this time, the impact block 22 is blocked by the pre-reset limiting plate 26 and kept at the high position of the slide groove 21 to complete energy storage until the swing arm 13 rotates to a critical angle close to the closure. The blocking plate 37 on the pull rope 28 cannot cross the blocking groove 30. As the floating ball 18 continues to push the detection end 15 to rotate upward, the horizontal plate 29 will pull the limiting plate 26 downward through the pull rope 28 and be stored in the slot 25, finally releasing the limiting plate 26 from limiting the impact block 22.

[0051] Subsequently, reference Figures 5 to 8 Under the action of gravity, the impact block 22 slides rapidly along the ball 32 toward the pressing end 14, and uses the accumulated kinetic energy to instantly impact the top of the valve stem 4, pushing the valve stem 4 to the closed position in one go. The locking block 9 is pushed back into the locking platform 11 by the locking spring 10 to complete the valve locking and realize instantaneous valve closure.

[0052] The entire process requires no manual intervention and can automatically follow water level changes to complete the rapid valve opening and closing action, effectively reducing the time that valve plate 5 is subjected to high-speed water flow, extending the service life of the equipment, and automatically completing lubrication maintenance, ensuring stable and reliable operation.

[0053] Throughout the entire operation of the equipment, refer to Figure 1 , Figure 3 and Figure 5 The bottom of the pull rope 28 is always in contact with water. The pull rope 28 gradually transports the water upward through capillary action and eventually delivers it to the slot 25. When the limiting plate 26 is pulled into the slot 25 by the pull rope 28, and when the impact block 22 passes over the limiting plate 26 and enters the energy storage position, the limiting plate 26 will cooperate with the slot 25 to squeeze the pull rope 28 part fixedly connected to the bottom of the limiting plate 26, squeezing the water inside the pull rope 28 into the slot 25. The squeezed water can enter the roller groove 31 through the lubrication ports 35 on the left and right sides of the slot 25, so that the roller balls 32 inside the roller groove 31 can be lubricated, ensuring that the impact block 22 can operate smoothly and stably.

[0054] The specific embodiment of the present invention has been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the embodiments described above.
