Description

Technical Field

[0001] This invention relates to the field of bathroom equipment technology, specifically to shower door structures. Background Technology

[0002] Currently, based on the different opening methods, common shower enclosures are generally divided into sliding door shower enclosures and revolving door shower enclosures. Among them, the door of a revolving door shower enclosure generally consists of a glass door frame and a rotating door installed in the glass door frame, with the rotating door and the glass door frame connected by hinges.

[0003] The aforementioned shower door system, where the rotating door and glass door frame are connected by hinges, requires manual closing by the user after opening. If the user neglects to close it, the door will remain in a half-open, suspended state for an extended period. Firstly, a half-open door is prone to shaking or tipping due to external impacts (such as family members entering or leaving the bathroom, or children accidentally touching it while playing), potentially causing injuries to the user and posing a risk of glass breakage. Secondly, the gap between the door and the frame can easily become a "hand trap," as children playing around in the bathroom may accidentally insert their fingers into the gap, causing injury. Thirdly, water overflowing from inside and outside the shower area will keep the dry area floor damp for extended periods, increasing the risk of slipping for users (especially the elderly and children), and causing mold to grow in the grout lines of the floor tiles and the waterproofing layer to age and leak due to prolonged soaking. Summary of the Invention

[0004] The purpose of this invention is to provide a shower door structure to solve the problem mentioned in the background art that the door will remain in a half-open and suspended state for a long time and cannot close automatically.

[0008] Preferably, the take-up and release assembly includes two winding wheels arranged coaxially, with steel wire rope wound on each of the two winding wheels. A connecting hook is fixed to one end of each steel wire rope. A rotating shaft is fixedly sleeved inside the central hole of each of the two winding wheels. The rotating shaft is connected to the output end of the speed-increasing component. One end of the connecting hook is fixedly connected to the cleaning assembly.

[0009] Preferably, the speed-increasing component includes an internal gear ring fixed to the top of the second bracket. Three sets of planetary gears are uniformly meshed on the inner side of the internal gear ring. A sun gear is meshed among the three sets of planetary gears.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1: Please refer to Figures 1-3 The shower door structure shown in the figure includes a glass door frame 1 and a glass revolving door 2. The glass revolving door 2 is rotatably connected to the glass door frame 1 via hinges. It also includes a bracket 3 fixed to the glass door frame 1 and a cylinder 4 fixed to the glass revolving door 2. Both ends of the cylinder 4 are screwed with end caps 5. An opening and closing control component 6 is installed inside the cylinder 4. A follower component 7 is connected between the bracket 3 and the opening and closing control component 6. A retraction component 8 is installed on the top of the cylinder 4. The output end of the retraction component 8 is provided with a cleaning component 9.

[0020] In this design, the opening and closing control component 6 and the follow-up component 7 work together to automatically return to their original positions and close tightly after the user opens the glass revolving door 2, completely blocking the overflow of water mist and water flow during the shower. At the same time, it can prevent water from seeping into the dry area of ​​the bathroom, effectively reducing the risk of elderly people and children slipping on wet floors, and also preventing children from getting their hands caught, providing safety protection for children playing around the bathroom. During the operation of the opening and closing control component 6, it will drive the retraction component 8 to move together. The retraction component 8 will drive the cleaning component 9 to move on the outer wall of the glass revolving door 2 near the shower room, thereby quickly cleaning water stains, shower gel foam, shampoo foam, hair and other easily attached impurities from the surface of the glass revolving door 2 after showering, reducing the amount of manual wiping work for the user.

[0021] For further details, please refer to [link / reference]. Figure 3 and Figure 4 The opening and closing control assembly 6 includes a piston 10 slidably connected inside the cylinder 4. A rack 11 is fixed to one side of the piston 10. A piston 2 12 is fixedly connected to the rack 11 through the piston 10. A one-way valve is installed on both the piston 10 and the piston 2 12. A return spring 13 is fixed to the side of the piston 10 away from the rack 11. The end of the return spring 13 away from the piston 10 is fixed to the inside of the end cover 5. Hydraulic oil is injected into the space of the cylinder 4 where the return spring 13 is located. The inner wall of the cylinder 4 is also provided with an oil passage 14 and an oil passage 2 15.

[0022] Additionally, see Figure 3 , Figure 5 and Figure 7The follower assembly 7 includes a telescopic rod 16 rotatably connected to the bracket 3. A pull rod 17 is rotatably connected to one end of the telescopic rod 16 away from the bracket 3. A driven shaft 18 is fixedly connected to one end of the pull rod 17. The driven shaft 18 is rotatably connected to the cylinder 4 through a bearing. A transmission gear 19 is fixedly sleeved on the outside of the driven shaft 18. The transmission gear 19 meshes with the rack 11. A bracket 20 is fixed to the top of the driven shaft 18. An acceleration element 21 is installed on the bracket 20. The output end of the acceleration element 21 is connected to the retracting assembly 8.

[0023] The principle of automatic closing of the glass revolving door 2: When the glass revolving door 2 is opened by the user's pushing force, the glass revolving door 2 drives the telescopic rod 16 and the pull rod 17 to move. The pull rod 17 drives the transmission gear 19 to rotate, thereby driving the rack 11 and the two pistons to move. The return spring 13 is compressed, and the hydraulic oil in the chamber where the return spring 13 is located is also pressurized. The piston 10 continuously squeezes the return spring 13 and the hydraulic oil. The hydraulic oil begins to enter the chamber between the piston 10 and the piston 2 12 through the oil channel 14. As the opening angle increases, the hydraulic oil fills the entire cylinder 4. At this time, the piston 10 is pushed by pressure, pushing the rack 11 outward, driving the transmission gear 19 to move. Wheel 19 rotates in the opposite direction, thereby driving the glass revolving door 2 to move in the closing direction. When the glass revolving door 2 is closed to a certain extent, the valve in the oil passage 2 15 automatically closes to prevent the hydraulic fluid from flowing back, thereby stopping the glass revolving door 2 from moving. As the glass revolving door 2 continues to close, there is still hydraulic oil in the chamber on one side of piston 2 12. Piston 2 12 continues to move and squeeze the hydraulic oil to generate a damping effect, thereby gradually slowing down the closing speed of the glass revolving door 2, so that the glass revolving door 2 closes slowly, avoiding the noise and damage caused by the glass revolving door 2 being closed forcefully. When the glass revolving door 2 is completely closed, the return spring 13 will reset piston 10 and piston 2 12 in cylinder 4 to prepare for the next opening.

[0024] Example 2: Please refer to Figure 6 - Figure 8 , Figure 10 as well as Figure 11 This embodiment further explains the first embodiment, and the difference lies in optimizing the effect of the glass revolving door 2.

[0025] Specifically, the take-up and release assembly 8 includes two winding wheels 22 arranged coaxially, with steel wire ropes 23 wound on each of the two winding wheels 22. A connecting hook 24 is fixed to one end of each steel wire rope 23. A rotating shaft 25 is fixedly sleeved in the central hole of each of the two winding wheels 22. The rotating shaft 25 is connected to the output end of the speed-increasing component 21. One end of the connecting hook 24 is fixedly connected to the cleaning assembly 9. The cleaning assembly 9 includes a bracket 30. A water-absorbing cotton roller 31 is rotatably connected to the bottom of the bracket 30. A fixing block 32 is fixedly connected to the top of the bracket 30. The connecting hook 24 is engaged with the fixing block 32.

[0026] Specifically, when the transmission gear 19 rotates, the speed-increasing component 21 drives the two winding wheels 22 to rotate multiple times, winding and unwinding the steel wire rope 23. During the unwinding process, the connecting hook 24 drives the absorbent cotton roller 31 to move downwards in conjunction, causing the absorbent cotton roller 31 to roll on the surface of the glass revolving door 2, wiping the surface of the glass revolving door 2 after a shower. This quickly cleans water stains, shower gel foam, shampoo foam, hair, and other easily adhered impurities from the surface of the glass revolving door 2 after a shower, reducing the amount of manual wiping work for the user. In addition, the connecting hook 24 and the fixing block 32 are engaged, making it easy to disassemble the absorbent cotton roller 31, allowing users to easily disassemble and clean the absorbent cotton roller 31 when cleaning the bathroom, and also making it easy for users to quickly install it.

[0027] Meanwhile, the speed-increasing component 21 includes an internal gear ring 26 fixed to the top of the bracket 20. Three sets of planetary gears 27 are evenly meshed on the inner side of the internal gear ring 26. A sun gear 28 is meshed among the three sets of planetary gears 27. The axle of the sun gear 28 is coaxially and fixedly connected to the rotating shaft 25. A planet carrier 29 is also rotatably connected to the planetary gear 27. The axle of the sun gear 28 is also rotatably connected to the planet carrier 29. The principle of speed-increasing transmission: The transmission gear 19 drives the driven shaft 18 to rotate. The driven shaft 18 drives the internal gear ring 26 to rotate through the bracket 20, so that the internal gear ring 26 is the input component. Then, through the transmission action of the three sets of planetary gears 27, the central sun gear 28 rotates. The sun gear 28 rotates faster than the internal gear ring 26 and rotates more times, so that the rotating shaft 25 can rotate more times, and thus the two winding wheels 22 can rotate more times. The wire rope 23 drives the cleaning component 9 to move up and down a longer distance, increasing the wiping area of ​​the absorbent cotton roller 31.

[0028] Meanwhile, it is worth noting that a protective cover 33 is provided on the outer side of the internal gear ring 26. A bracket 4 34 is fixed to the bottom of the protective cover 33. The bottom of the bracket 4 34 is fixed to the top of the cylinder body 4. The planetary carrier 29 is fixedly connected to the inner wall of the protective cover 33. The designed protective cover 33 can shield the speed-increasing component 21 and the winding wheel 22 to prevent moisture from entering and corroding the gears. It can also limit the planetary carrier 29 to ensure that the planetary gear 27 can be limited so that it can only rotate on its own axis and cannot revolve around the sun.

[0029] It should be noted that pulleys 37 are fixed at both ends of the cylinder 4, and the wire rope 23 is slidably connected to the pulleys 37. The pulleys 37 can effectively change the direction of force on the wire rope 23, making its operation more stable and smooth, reducing the wear of the wire rope 23, and extending the service life of the wire rope 23. At the same time, the pulleys 37 are made of high-strength and wear-resistant materials, which can withstand the tension and friction generated by the wire rope 23 during long-term operation, ensuring the stability and reliability of the entire cleaning assembly 9 during its up-and-down movement.

[0030] Example 3: Please refer to Figure 8 and Figure 9 This embodiment further illustrates other embodiments, with the difference being the optimization of the connecting components between the bracket 30 and the glass revolving door 2.

[0031] Specifically, the cleaning component 9 includes a bracket 30, with an absorbent cotton roller 31 rotatably connected to the bottom of the bracket 30, and a fixing block 32 fixedly connected to the top of the bracket 30. The connecting hook 24 is engaged with the fixing block 32. Both ends of the bracket 30 are fixed with pulleys 35, and a limit strip 36 is fixed to the surface of the glass revolving door 2. The pulleys 35 are slidably connected to the limit strip 36.

[0032] It should be noted that the sliding connection between pulley 35 and limit bar 36 enables flexible and stable relative movement between bracket 30 and glass revolving door 2. This not only ensures the smoothness of the cleaning component 9 during movement, but also effectively limits the range of movement of pulley 35 through limit bar 36. This ensures that the cleaning component 9 can accurately move along the surface of glass revolving door 2, improving the cleaning effect. At the same time, the design of pulley 35 also reduces the friction between it and glass revolving door 2, reducing noise and wear during operation and extending the service life of bracket 30.

[0033] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
