Movable swimming pool platform

Abstract

This utility model discloses a movable swimming pool platform, relating to the field of swimming pool platform technology. The utility model includes a platform body, with a displacement component fixedly connected to the inner cavity of the platform body, and a sealing component fixedly connected to the bottom of the inner cavity of the platform body. The design of the displacement component of this utility model enables convenient retraction and extension of the casters, significantly improving the mobility and equipment protection of the swimming pool platform. In the displacement component, the meshing transmission between the worm gear and the large worm wheel drives the screw tube to rotate, causing the lead screw to rise and fall axially, thereby controlling the vertical displacement of the mounting plate and the four corner casters. When movement is needed, inserting an external hexagonal wrench into the inner cavity of the countersunk hole and rotating it allows the casters to quickly extend to the bottom of the platform body to contact the ground, achieving easy platform relocation using their flexible steering characteristics. When movement is not needed, the reverse operation retracts the casters into the platform cavity, avoiding wheel axle corrosion and jamming problems caused by long-term exposure.

Description

Technical Field

[0001] This utility model belongs to the field of swimming pool platform technology, and in particular relates to a movable swimming pool platform. Background Technology

[0002] With the diversification of leisure and entertainment facilities, pool platforms, as supporting equipment for swimming pools, are widely used in commercial pools, family pools, and public water sports venues. Pool platforms not only provide spaces for people to stand, rest, and place equipment, but their ease of movement and environmental adaptability have also become key concerns for users.

[0003] Traditional pool platforms are mostly fixedly installed, connected to the surrounding ground via embedded parts or bolts. While this ensures structural stability, it has significant drawbacks: Adjusting the platform's position requires heavy equipment like forklifts, which is cumbersome and prone to damaging the platform and the ground. Although some mobile pool platforms are equipped with casters, these are often exposed at the bottom of the platform, constantly immersed in the humid environment around the pool. This makes the axles and rotating parts susceptible to corrosion and rust, leading to jamming or even failure of the casters, severely impacting the platform's mobility. Furthermore, existing mobile platforms often lack effective sealing around the caster installation areas when stationary. Pool splashes or wastewater from the ground can seep into the platform's interior through the caster mounting holes, causing corrosion and damage to internal load-bearing structures, electrical components, or transmission parts, significantly shortening the equipment's lifespan.

[0004] To address these issues, we offer a movable pool platform. Utility Model Content

[0005] The purpose of this invention is to provide a movable swimming pool platform. By combining the displacement component and the sealing component, it solves the problems of existing swimming pool platforms being inconvenient to move and lacking a sealing structure.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a movable swimming pool platform, comprising a platform body. A displacement assembly is fixedly connected to the inner cavity of the platform body, and a sealing assembly is fixedly connected to the bottom of the inner cavity. The displacement assembly includes a support plate fixedly connected to the platform body. A helical tube is fixedly connected to the bottom of the support plate via a bearing. A lead screw is threadedly connected to the inner cavity of the helical tube. A mounting plate is fixedly connected to the bottom of the lead screw. Universal wheels are fixedly connected to the four corners of the bottom of the mounting plate. A large worm gear is fixedly connected to the bottom of the surface of the helical tube. A worm is engaged with the surface of the large worm gear. The other end of the worm is fixedly connected to the inner wall of the platform body via a bearing, and a drive pulley is fixedly connected to the other end of the worm. The sealing assembly includes a second lead screw fixedly connected to the bottom of the inner cavity of the platform body via a bearing seat. Through holes for the universal wheels are opened at the four corners of the bottom of the platform body. A moving groove is opened at the top of the through hole. A sealing plate is slidably connected to the inner cavity of the moving groove. Both ends of the second lead screw are threadedly connected to the sealing plate, and a linkage is fixedly connected to the surface of the second lead screw.

[0008] The present invention is further configured such that handrails are fixedly connected to both the front and rear ends of the top of the platform body, and a reinforcing rod is fixedly connected to the inner cavity of the platform body below the step. The handrails at the top of the platform facilitate manual pushing or fixing of the platform, enhancing the ease of operation; the reinforcing rod below the step enhances the structural strength of the platform body and prevents deformation when bearing weight.

[0009] The present invention is further configured such that a limiting tube is fixedly connected to the bottom of the support plate and to both sides of the screw tube, and a limiting rod is slidably connected to the inner cavity of the limiting tube. The bottom of the limiting rod is fixedly connected to the top of the mounting plate. The sliding cooperation between the limiting tube and the limiting rod provides guidance for the mounting plate, preventing the lead screw from deflecting when it is raised or lowered, and ensuring that the caster wheel extends or retracts smoothly.

[0010] The present invention is further configured such that the mounting plate adopts a hollow design, and the four sides of the mounting plate do not contact the inner wall of the platform body. The hollow design of the mounting plate reduces the overall weight and maintains a distance from the inner wall of the platform, avoiding frictional resistance during movement and improving the transmission efficiency of the displacement component.

[0011] The present invention is further configured such that both ends of the lead screw are provided with external threads, and the external threads at both ends are designed in opposite directions. The reverse threads at both ends of the lead screw cause the sealing plates on both sides to move in opposite directions synchronously, ensuring uniform force and tight fit during sealing, and avoiding sealing failure caused by misalignment on one side.

[0012] The present invention is further configured such that the linkage includes a bevel gear one fixedly connected to the surface of the lead screw two, a bevel gear two meshing on the surface of the bevel gear one, a transmission shaft fixedly connected between the two bevel gears two, both ends of the transmission shaft being fixedly connected to the bottom of the inner cavity of the platform body through bearing seats, a small worm gear fixedly connected to the surface of the transmission shaft, a worm gear two meshing on the top of the small worm gear, and the other end of the worm gear two penetrating to the outside of the platform body and fixedly connected to a driven pulley. The linkage transmits the power of the displacement component to the sealing component synchronously through the bevel gear set, the worm gear, and the worm gear, realizing the linkage control of the universal wheel retraction and the sealing plate closure, simplifying the operation steps.

[0013] The present invention is further configured such that the driven belt pulley and the driving belt pulley are connected by belt drive, and the surface of the driving belt pulley is provided with a countersunk hole. The belt drive structure realizes the power coupling between the driving belt pulley and the driven belt pulley, ensuring that the displacement component and the sealing component operate synchronously. The countersunk hole design facilitates the installation and fixing of external drive components.

[0014] The present invention is further configured such that a sealing ring is fitted on the surface of the sealing plate, and the sealing ring is in close contact with the inner wall of the moving groove. The sealing ring on the surface of the sealing plate is in close contact with the inner wall of the moving groove, forming a flexible sealing barrier, enhancing waterproof performance, and preventing water vapor from seeping in due to tiny gaps.

[0015] The present invention has the following beneficial effects.

[0016] 1. The design of this utility model's displacement component enables convenient retraction and extension of the casters, significantly improving the mobility and equipment protection of the pool platform. In the displacement component, the meshing transmission between the worm gear and the large worm wheel drives the screw tube to rotate, causing the lead screw to rise and fall axially, thereby controlling the vertical displacement of the mounting plate and the four corner casters. When movement is needed, inserting the external hexagonal wrench into the inner cavity of the countersunk hole and rotating it allows the casters to quickly extend to the bottom of the platform body to contact the ground, enabling easy platform relocation using their flexible steering characteristics. When no movement is needed, the reverse operation retracts the casters into the platform's inner cavity, avoiding the problems of wheel axle corrosion and jamming caused by long-term exposure. The cooperation between the limit tube and the limit rod ensures the smooth lifting and lowering of the mounting plate, and the hollow design of the mounting plate reduces friction with the inner wall of the platform. The entire structure achieves automated control of the casters through mechanical transmission, meeting the movement needs in different scenarios and effectively extending the service life of the casters, solving the reliability problem caused by exposed casters in traditional mobile platforms.

[0017] 2. The linkage design of the sealing component and the displacement component of this utility model constructs a complete waterproof protection system, fundamentally blocking the path of water vapor intrusion into the platform's inner cavity. In the sealing component, the reverse threads at both ends of the lead screw are connected to the threads of the sealing plate. With the help of the bevel gear set and worm gear and worm drive of the linkage component, the two sealing plates can be driven to open and close synchronously. When the universal wheel retracts into the inner cavity, the external drive drives the driven belt pulley synchronously through the belt drive, causing the worm gear to mesh with the small worm gear and rotate. The power is transmitted through the transmission shaft and the bevel gear set. The rotation of the lead screw drives the sealing plate to slide along the moving groove, completely covering the bottom through hole and tightly fitting the groove wall through the sealing ring, forming a fully enclosed sealing structure. This design not only prevents pool splashes and ground sewage from seeping in through the universal wheel mounting holes, but also prevents moisture from corroding the platform's internal load-bearing structure and transmission components, significantly improving the equipment's durability in humid environments. The coordinated action of the sealing plate and the displacement component requires no additional operation steps, realizing integrated control of the moving function and waterproof performance, meeting the stringent environmental adaptability requirements of high-end swimming pool equipment.

[0025] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

Universal wheels 25 are fixedly connected to the four corners of the bottom of the mounting plate 24. A large worm gear 26 is fixedly connected to the bottom of the surface of the screw tube 22. The surface of the worm gear 27 is engaged with the platform body 1. The other end of the worm gear 27 is fixedly connected to the inner wall of the platform body 1 through a bearing. The other end of the worm gear 27 is fixedly connected to the drive pulley 28. The sealing assembly 3 includes a screw rod 31 fixedly connected to the bottom of the inner cavity of the platform body 1 through a bearing seat. The four corners of the bottom of the platform body 1 are provided with through holes 32 for universal wheels 25. The top of the through holes 32 is provided with a moving groove 33. The inner cavity of the moving groove 33 is slidably connected to a sealing plate 34. The two ends of the screw rod 31 are threadedly connected to the sealing plate 34. The surface of the screw rod 31 is fixedly connected to a linkage 35.

[0028] Specifically: When operating the active belt pulley 28, the worm gear 27 drives the large worm wheel 26 to rotate, which in turn drives the solenoid tube 22 to rotate synchronously. The lead screw 23 moves up and down axially due to the threaded transmission, thereby controlling the vertical displacement of the mounting plate 24 and the universal wheel 25. The limiting tube 29 is fixed to both sides of the bottom of the support plate 21 and slides with the limiting rod 210 on the top of the mounting plate 24 to ensure that the lifting process is smooth and without deviation. When the active belt pulley 28 rotates, the power is transmitted to the driven belt pulley 356 via the belt. The worm gear 355 drives the small worm wheel 354 to rotate the transmission shaft 353. The bevel gear set meshes to make the lead screw 31 rotate. The reverse thread drives the sealing plates 34 on both sides to move closer or further away synchronously, thereby achieving the sealing and opening of the through hole 32.

[0029] Example 2

[0030] Please see Figure 1-5Based on Embodiment 1, handrails are fixedly connected to both the front and rear ends of the top of the platform body 1. A reinforcing rod is fixedly connected to the inner cavity of the platform body 1 below the step. Limiting tubes 29 are fixedly connected to the bottom of the support plate 21 on both sides of the screw tube 22. Limiting rods 210 are slidably connected to the inner cavity of the limiting tubes 29. The bottom of the limiting rods 210 is fixedly connected to the top of the mounting plate 24. The mounting plate 24 adopts a hollow design, and the four sides of the mounting plate 24 do not contact the inner wall of the platform body 1. Both ends of the lead screw 31 are provided with external threads, and the external threads at both ends are designed in opposite directions. The linkage 35 includes a bevel gear 351 fixedly connected to the surface of the lead screw 31. A bevel gear 352 meshes with the surface of 351. A drive shaft 353 is fixedly connected between the two bevel gears 352. Both ends of the drive shaft 353 are fixedly connected to the bottom of the inner cavity of the platform body 1 through bearing seats. A small worm gear 354 is fixedly connected to the surface of the drive shaft 353. A worm 355 meshes with the top of the small worm gear 354. The other end of the worm 355 extends to the outside of the platform body 1 and is fixedly connected to a driven pulley 356. The driven pulley 356 and the driving pulley 28 are connected by belt drive. A countersunk hole is opened on the surface of the driving pulley 28. A sealing ring is fitted on the surface of the sealing plate 34. The sealing ring is in close contact with the inner wall of the moving groove 33.

[0031] Specifically: the handrail at the top of the platform facilitates manual pushing or securing of the platform, enhancing operational convenience; the reinforcing rod below the steps enhances the structural strength of the platform body 1, preventing deformation under load; the sliding fit between the limiting tube 29 and the limiting rod 210 provides guidance for the mounting plate 24, preventing skew during the lifting and lowering of the lead screw 23, ensuring the smooth extension or retraction of the casters 25; the hollowed-out design of the mounting plate 24 reduces the overall weight and maintains a distance from the inner wall of the platform, avoiding frictional resistance during movement and improving the transmission efficiency of the displacement assembly 2; the reverse threads at both ends of the lead screw 31 cause the sealing plates 34 on both sides to move synchronously in opposite directions, ensuring uniform force during sealing. The fit is tight, avoiding sealing failure caused by misalignment on one side. The linkage 35 transmits the power of the displacement component 2 to the sealing component 3 synchronously through the bevel gear set and worm gear and worm drive, realizing the linkage control of the retraction of the universal wheel 25 and the closing of the sealing plate 34, simplifying the operation steps. The belt drive structure realizes the power coupling between the active belt pulley 28 and the driven belt pulley 356, ensuring that the displacement component 2 and the sealing component 3 move synchronously. The countersunk hole design facilitates the installation and fixing of external drive components. The sealing ring on the surface of the sealing plate 34 is in close contact with the inner wall of the moving groove 33, forming a flexible sealing barrier, enhancing waterproof performance, and preventing water vapor from seeping in due to tiny gaps.

[0032] The working principle of this utility model is as follows: When the pool platform needs to be moved, external power acts on the active belt pulley 28, which drives the driven belt pulley 356 to rotate synchronously via belt transmission. The active belt pulley 28 drives the worm gear 27 to rotate, meshing with the large worm wheel 26 to drive the screw tube 22 to rotate. The lead screw 23 extends downward due to the threaded transmission, pushing the mounting plate 24 and the caster wheel 25 down to the bottom of the platform body 1 to contact the ground. The limiting rod 210 slides synchronously within the limiting tube 29 to ensure stability. The driven belt pulley 356 drives the worm gear 355 to rotate, meshing with the large worm wheel 26 to drive the large worm wheel 27 to rotate. The small worm gear 354 rotates the drive shaft 353, which drives the lead screw 31 to rotate through the bevel gear set. The reverse threads at both ends push the sealing plate 34 to move to both sides, opening the bottom through hole 32 and allowing the caster wheel 25 to extend. When the platform is in fixed use, the reverse operation of the drive structure causes the caster wheel 25 to rise with the lead screw 23 and retract into the platform cavity. The mounting plate 24 returns to its initial position, and the sealing plate 34 moves towards the center under the drive of the lead screw 31, completely covering the through hole 32. The sealing ring fits tightly against the inner wall of the moving groove 33, blocking the path of water vapor.
