Description

Technical Field

[0001] This utility model relates to the field of bathroom products, and more specifically to a synchronous operation error elimination installation structure and its lifting toilet and lifting cabinet. Background Technology

[0002] Existing lift toilets use nuts to fix the lifting structure to the base. During installation, multiple lead screws are assembled with nuts on the base, and then a synchronous pulley is installed on the upper end of each lead screw. The drive mechanism can be a motor, and a synchronous pulley is also assembled on the output shaft of the motor. Finally, the synchronous belt is connected to the synchronous pulley to complete the installation of the entire transmission mechanism. The drive mechanism drives the synchronous belt or chain to drive the multiple lead screws, thereby driving the lifting / lowering of the toilet bowl or other devices connected to the lead screws.

[0003] However, in existing lifting structures, nuts are generally fixed to the base or threaded holes are directly drilled in the base. Therefore, the lead screws must be connected to the base first, and then the timing pulley and timing belt are installed to complete the installation. This installation method will cause some lead screws to rotate when the timing belt is installed, which will cause the platform height supported by each lead screw to change inconsistently. As a result, the lifting will be unstable or jammed after installation. Multiple adjustments are required during the assembly process, making the installation extremely inconvenient.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] First embodiment:

[0027] A synchronous operation error elimination installation structure, such as Figures 1 to 3As shown, the system includes a first body, a second body, a timing belt 3, a drive mechanism, and at least two lead screws 6. The lead screws 6 are detachably mounted on the second body. One of the lead screws 6 and the nut 9 is equipped with a timing pulley 4. The drive mechanism drives the timing pulleys 4 to rotate via the timing belt 3, thereby causing one of the lead screws 6 and the nut 9 to rotate synchronously. The first body has mounting portions corresponding to the lead screws 6, and each mounting portion is detachably connected to a nut 9 that is threaded into the lead screw 6. In this embodiment, the lead screw 6 is equipped with a timing pulley 4, and the drive mechanism drives the timing pulleys 4 to rotate via the timing belt 3, thereby causing the lead screws 6 to rotate synchronously. The first body is a base 1, and the second body is a support plate 2 that can move relative to the base 1.

[0028] Both the lead screw 6 and the drive mechanism are fixed on the support plate 2. The lead screw 6 is equipped with a synchronous pulley 4, which is fixed to the lead screw 6. When the synchronous pulley 4 rotates, the lead screw 6 will rotate together. The drive mechanism drives each synchronous pulley 4 to rotate through the synchronous belt 3, thereby driving each lead screw 6 to rotate synchronously.

[0029] The base 1 is provided with mounting parts corresponding to the lead screws 6. Each mounting part is detachably connected to a nut 9 that is threaded into the lead screw 6. The base also includes a first limiting component that circumferentially limits the nut 9 within the mounting part. The first limiting component includes a limiting rib 14 and a limiting groove 15. The limiting rib 14 is located on one of the mounting part and the nut 9, and the limiting groove 15 is located on the other. The limiting rib 14 and the limiting groove 15 cooperate to limit the nut 9 circumferentially relative to the mounting part, preventing rotation.

[0030] The base 1 has a boss 10. The mounting part includes a mounting groove 7 on the top of the boss 10 and a fixing sleeve 8 that is circumferentially limited and installed in the mounting groove 7. The fixing sleeve 8 has a through hole for inserting a nut 9. The lead screw 6 can be inserted into the mounting groove 7 and move up and down along the mounting groove 7. After the lead screw 6 is equipped with the synchronous pulley 4 and the synchronous belt 3, the nuts 9 can be assembled with the lead screw 6 first. After all the nuts 9 are adjusted to the same height, they are then inserted into the fixing sleeve 8 to ensure the balance of the lifting platform and avoid inconsistent heights. A first limiting component is provided between the fixing sleeve 8 and the nuts 9 to limit the rotation of the nuts 9, so that the nuts 9 remain stationary when the lead screw 6 rotates, thus realizing the lifting and lowering of the lead screw 6.

[0031] In this embodiment, the drive mechanism uses a motor 5, which is fixed to the bottom of the support plate 2. A synchronous pulley 4 is also fixed on the output shaft of the motor 5. The synchronous belt 3 and each synchronous pulley 4 are located below the support plate 2. The synchronous belt 3 connects each lead screw 6 and the synchronous pulley 4 of the motor 5. When the motor 5 is turned on, it drives the synchronous belt 3 to move through the synchronous pulley 4, thereby driving the synchronous pulley 4 on each lead screw 6 to rotate synchronously.

[0032] The mounting groove 7 extends vertically towards the bottom of the boss 10, providing clearance for the lead screw 6 when the support plate 2 descends. A first protruding edge 11 is provided at the top of the fixing sleeve 8, integrally formed with the fixing sleeve 8. When the fixing sleeve 8 is inserted into the mounting groove 7, the first protruding edge 11 fits against the top of the boss 10, thus confining the fixing sleeve 8 at the top of the mounting groove 7. The peripheral sidewall of the fixing sleeve 8 fits against the inner wall of the mounting groove 7. A second protruding edge 12 is provided at the top of the nut 9, integrally formed with the nut 9. When the nut 9 is inserted into the fixing sleeve 8, the second protruding edge 12 fits against the first protruding edge 11, thus confining the nut 9 at the top of the fixing sleeve 8. First limiting components are respectively provided on the upper end face of the first protruding edge 11 and the lower end face of the second protruding edge 12.

[0033] A second limiting component can also be detachably connected to the boss 10. The second limiting component includes a pressure cover 13, which covers the top of the nut 9 to limit the nut 9 along the axial direction. The pressure cover 13 is fixed to the top of the boss 10 by a screw 16. The nut 9 is clamped between the fixing sleeve 8 and the pressure cover 13, thereby fixing the nut 9. The pressure cover 13 has a through hole for the lead screw 6 to pass through. When assembling the nut 9 and the lead screw 6, the pressure cover 13 must be put into the lead screw 6 first and then the nut 9 and the lead screw 6 are connected.

[0034] The fixing sleeve 8 is detachably connected to the boss 10 via screws 16 on the first protruding edge 11, fixing the fixing sleeve 8 and preventing it from rotating. A limiting strip 17 protrudes from the peripheral sidewall of the fixing sleeve 8, and a limiting slide 18 is formed in the inner wall of the mounting groove 7. The limiting slide 18 extends vertically downward from the top of the mounting groove 7. When the fixing sleeve 8 is inserted into the mounting groove 7, the limiting strip 17 inserts into the limiting slide 18, providing quick positioning for the installation of the fixing sleeve 8, aligning the screw holes 16 on the fixing sleeve 8 with the boss 10, and further restricting the rotation of the fixing sleeve 8 to improve stability. In this embodiment, four limiting strips 17 are provided on the peripheral sidewall of the fixing sleeve 8, equidistantly arranged along the peripheral sidewall of the fixing sleeve 8.

[0035] like Figure 4 As shown, in this embodiment, the first limiting component includes a limiting rib 14 protruding from the upper end face of the first protrusion 11. At least one limiting rib 14 is provided and arranged circumferentially along the upper end face of the first protrusion 11. A limiting groove 15 corresponding to the limiting rib 14 is opened on the lower end face of the second protrusion 12. When the nut 9 is inserted into the fixing sleeve 8, the limiting rib 14 is inserted into the limiting groove 15, restricting the rotation of the nut 9. The nut 9 and the fixing sleeve 8 cannot rotate relative to each other.

[0036] The top of the limiting rib 14 has chamfers 20 on both sides, and the opening of the limiting groove 15 also has chamfers 20 on both sides. The chamfers 20 serve as guides, making it easier for the limiting rib 14 to pass into the limiting groove 15 and less likely to get stuck.

[0037] In this embodiment, four bosses 10 are provided, arranged in a rectangular pattern, and located at the four corners of the base 1 respectively.

[0038] This embodiment also includes a positioning fixture for positioning and adjusting the nuts 9. The positioning fixture uses a sleeve of fixed length. When installing the nuts 9, the sleeve is first inserted into the lead screw 6, and the nuts 9 are moved to the bottom of the sleeve, so that the distance between each nut 9 and the timing pulley 4 is the same.

[0039] The installation process of this utility model is as follows:

[0040] After assembling the timing belt 3, timing pulley 4, lead screw 6, and support plate 2, put the cover and nuts into the lead screw 6. Then, use the positioning fixture to make each nut 9 fit into the same height position on the lead screw 6. Then, insert the lead screw 6 into the mounting groove 7 and make the nuts 9 fit into the fixing sleeve 8. The limiting rib 14 and the limiting groove 15 are engaged. Finally, fix the screw 16 on the cover to complete the installation. With this method of installation, the timing belt will not rotate throughout the entire process.

[0041] Second embodiment:

[0042] A synchronous operation error elimination installation structure, such as Figure 5 As shown, the difference from the first embodiment is that in this embodiment, the first limiting component is disposed on the outer periphery of the nut 9 and the inner periphery of the through hole of the fixing sleeve 8. The first limiting component includes a limiting rib 14 protruding from the periphery of the nut 9, and a limiting groove 15 corresponding to the limiting rib 14 is provided on the inner wall of the through hole of the fixing sleeve 8. The limiting groove 15 extends vertically downward from the top of the fixing sleeve 8. When the nut 9 is inserted into the fixing sleeve 8, the limiting rib 14 is inserted into the limiting groove 15, restricting the rotation of the nut 9, and the nut 9 and the fixing sleeve 8 cannot rotate relative to each other.

[0043] The bottom end of the limiting rib 14 is chamfered 20, and the top end of the limiting groove 15 is also chamfered 20. The chamfers 20 between adjacent limiting grooves 15 are adjacent and serve as guides, making it easier for the limiting rib 14 to pass into the limiting groove 15 and less likely to get stuck.

[0046] Fourth embodiment:
