Description

Technical Field

[0001] This invention relates to the field of integrated washbasin installation technology, specifically to an integrated washbasin installation structure based on assembly. Background Technology

[0002] A washbasin is a type of sanitary ware, and its development trend is towards water conservation, environmental friendliness, aesthetics, and hygiene. Washbasins are further divided into two types: countertop basins and undermount basins. This is not a difference in the basin itself, but rather a difference in installation.

[0003] Existing prefabricated washbasins use a standardized mounting bracket installation method. The bracket and the washbasin mounting frame are usually fixed structures. Although this is convenient for assembly, the bracket and mounting frame cannot automatically change the installation points according to the size of the washbasin. This can easily lead to unreasonable support points for the washbasin, causing it to wobble or even fall. Secondly, existing prefabricated washbasins require bolt fixing. For aesthetic reasons, the bolts are usually located at the bottom of the washbasin, requiring the operator to reach under the washbasin to operate. However, the height of the washbasin from the ground is too small, making it extremely inconvenient for the operator.

[0004] Based on this, the present invention designs an integrated washbasin installation structure based on assembly to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide an assembled, integrated washbasin installation structure to address the shortcomings of the prior art as described in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An assembly-based integrated washbasin installation structure includes a base mechanism. The base mechanism includes an elongated oval base plate for mounting to a wall. An elongated oval groove is formed on the side wall of the elongated oval base plate. Two sliding plates are laterally slidably arranged on the upper and lower side walls of the elongated oval groove. The two sliding plates are symmetrically arranged about the central front-rear axis of the elongated oval base plate. A first ring plate is fixedly connected to the near ends of the two sliding plates. The edge of the first ring plate is tangent to the edge of the sliding plate. A notch is formed on the first ring plate to allow the sliding plates to pass through. A first round rod is provided at the center of each first ring plate. A locking block with a smaller front end and a larger rear end is fixedly provided at the end of each first round rod away from the first ring plate. The locking blocks have rounded corners on their left and right sides. The elongated oval base plate has an assembly plate fixedly adjacent to the washbasin. The assembly plate has two through holes for the two locking blocks to pass through. The assembly plate also has two elongated oval grooves for engaging with the first round rods, and the two elongated oval grooves communicate with the two through holes respectively. A drive mechanism is provided at the center of the elongated oval base plate to drive the two first ring plates to move away from each other after the locking blocks pass through the through holes.

[0008] As a further embodiment of the present invention, the driving mechanism includes a first gear rotatably disposed in the center of the elongated bottom groove, and first teeth are provided on the sidewalls of the two slide plates that are close to each other. The first gear meshes with the first teeth on the sidewalls of the two slide plates. A spring is provided on the inner wall of the rear end of the first gear. One end of the spring is fixedly connected to the first gear, and the other end is fixedly connected to the sidewall of the elongated bottom groove.

[0009] As a further embodiment of the present invention, a first spring is sleeved on the outer wall of the first round rod located between the first ring plate and the locking block, and a second ring plate is sleeved on the outer wall of the first round rod. One end of the first spring is fixedly disposed on the side wall of the first ring plate, and the other end is fixedly disposed on the second ring plate.

[0010] As a further embodiment of the present invention, a through hole is provided in the center of the first ring plate, the first round rod is sleeved in the through hole, a second elongated through groove is provided on the elongated bottom groove, the first round rod passes through the second elongated through groove, an elongated stepped groove with the same center line as the second elongated through groove is provided at the rear end of the elongated bottom plate, and the height of the upper side wall of the elongated stepped groove is far from the center line, and a friction wheel is coaxially provided at one end of the first round rod that passes through the elongated bottom plate, and the friction wheel is in contact with the lower side wall of the elongated stepped groove.

[0011] As a further embodiment of the present invention, the friction wheel is screwed to the first round rod, the side wall of the through hole is provided with a 90-degree rotating groove, and a limit key is fixedly provided on the outer wall of the first round rod, the limit key being inside the rotating groove.

[0012] As a further embodiment of the present invention, two water pipe joints are symmetrically fixed on the front end face of the elongated bottom plate about the front and rear central axes. A locking bolt is rotatably connected to the water pipe joint. The outer wall of the locking bolt is provided with a second tooth. A second rack that meshes with the locking bolt is fixed on the front end face of both slide plates. Two basin water inlet pipes are provided on the assembly plate. The rear threads of the two basin water inlet pipes are respectively engaged with the locking bolt.

[0013] As a further embodiment of the present invention, the basin inlet pipe is axially slidably connected to the assembly plate, and a second spring is sleeved on the outer wall of the basin inlet pipe. One end of the second spring is fixed to the assembly plate, and the other end is fixed to the basin inlet pipe.

[0014] As a further embodiment of the present invention, a support plate that can be cast into concrete for support is fixedly provided on the rear section of the front end face of the elongated bottom plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. This invention utilizes a locking block at the end of the first round rod to engage with a through hole on the assembly plate. Subsequently, a drive mechanism drives the sliding plate and the first ring plate to move away from each other on the elongated bottom groove. This causes the two sets of first round rods and locking blocks to move away from each other, expanding the support range on one hand, and on the other hand, the first round rod carries the locking block from the middle through hole to the elongated groove, thereby achieving a locking mechanism and avoiding the inconvenience of bolt locking. Furthermore, the locking of assembly plates of different lengths by the first round rod and locking block inside the fixed-length base mechanism further enhances the applicability of the equipment.

[0017] 2. This invention activates the drive mechanism by cutting the disposable ropes outside the two first round rods. The spring-loaded springs drive the first gear to rotate, which in turn drives the first teeth on the sidewall of the sliding plate. This causes the two sliding plates to move towards both ends on the inner wall of the elongated bottom groove. The movement of the two sliding plates drives the two first ring plates to move away from each other, thereby allowing the first round rods to move the carrying block into the elongated groove of the assembly plate, thus locking the assembly plate with the basin. When the first round rod moves to the end of the elongated groove, a small portion of the spring-loaded spring remains in an unrecovered state, thus maintaining the locking force. This avoids the loosening that occurs during long-term use of the basin when using conventional bolt locking, which can cause the basin to wobble.

[0018] 3. The present invention reduces the shaking of the assembly plate by causing the assembly plate to press against the second ring plate when the card block is inserted into the through hole of the assembly plate. This ensures that the first spring on the first ring plate always applies pressure to the second ring plate, and the second ring plate is always pressed against the assembly plate, thereby reducing the shaking of the assembly plate and preventing the basin from shaking and falling off during use.

[0019] 4. In this invention, as the first round rod moves with the first ring plate, it slides laterally within the second elongated groove. This causes the friction wheel to move laterally with the first round rod, subjecting it to friction from the elongated stepped groove. This causes the first round rod to rotate, and the limiting key rotates 90 degrees within the rotating groove, stopping the first round rod from rotating. The friction wheel rotates around the first round rod, pulling it closer to the elongated bottom plate, thus bringing the assembly plate closer to the first ring plate. This increases the pressure of the first spring, improving the clamping force on the assembly plate and preventing the basin from shaking during use. Furthermore, the locking block rotates on the outer wall of the elongated groove on the assembly plate, creating a 90-degree angle between the block's lateral axis and the center line of the groove. This allows for a larger vertical overlap of the locking block with the assembly plate, preventing torsional forces around the end of the first round rod that could cause the basin to rotate.

Detailed Implementation

[0033] 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.

[0034] Please see Figure 1-10 This invention provides a technical solution: a modular, integrated washbasin installation structure, including a base mechanism. The base mechanism includes an elongated oval base plate 10 for mounting to a wall. An elongated oval groove 11 is formed on the side wall of the elongated oval base plate 10. Two sliding plates 12 are laterally slidably arranged on the upper and lower side walls of the elongated oval groove 11. The two sliding plates 12 are symmetrically arranged about the central front-rear axis of the elongated oval base plate 10. A first ring plate 13 is fixedly connected to the adjacent ends of each sliding plate 12. The edge of the first ring plate 13 is tangent to the edge of the sliding plate 12. A notch 14 is formed on the first ring plate 13 to avoid the sliding plate 12. A notch 14 is formed in the center of each first ring plate 13. Each is equipped with a first round rod 15. Each first round rod 15 has a locking block 16 with a smaller front end and a larger rear end fixedly installed at the end away from the first ring plate 13. The locking block 16 has rounded corners 17 on its left and right sides. The elongated oval base plate 10 is equipped with an assembly plate 18 that is fixedly adjacent to the basin. The assembly plate 18 has two through holes 19 for the two locking blocks 16 to pass through. The assembly plate 18 also has two elongated oval grooves 20 for cooperating with the first round rod 15. The two elongated oval grooves 20 are respectively connected to the two through holes 19. The center of the elongated oval base plate 10 is equipped with a drive mechanism for driving the two first ring plates 13 to move away from each other after the locking blocks 16 pass through the through holes 19.

[0035] Before using this invention, assemble the device, transport it to the installation site, and then fix the elongated base plate 10 onto the wall where it is to be installed. Figure 1 As shown, Figure 1 This device is rotated 90 degrees counterclockwise, where Figure 1 The front end of the device is viewed from right to left, and the right end of the device is viewed from top to bottom in the diagram. The following descriptions will use the device's orientation and will not be repeated.

[0036] In use, the assembly plate 18 and the basin assembly are lifted as a whole and brought closer to the elongated oval base plate 10, as shown. Figure 1 and 2As shown, the locking block 16 passes through the through hole 19. The locking block 16 has a smaller front end and a larger rear end, making it easier for the locking block 16 to pass through the through hole 19 in the vertical direction (it has a certain guiding effect). Secondly, the design of the rounded corner 17 also avoids too many sharp corners of the locking block 16, which would make it difficult to pass through the through hole 19. Secondly, the wider through hole 19 allows the locking block 16 to pass through the through hole 19 in the horizontal direction. Moreover, the left and right ends of the through hole 19 have a certain redundancy design for the locking block 16, so that the assembly plate 18 and the basin assembly have a certain allowable wobble error range in the horizontal direction. Therefore, during blind assembly, the assembly plate 18 and the basin assembly are more likely to be locked onto the locking block 16. After the locking block 16 passes through the through hole 19, the drive mechanism is activated, and the two first ring plates 13 move away from each other on the inner wall of the elongated bottom groove 11 (the design of the two sliding plates 12 and the notch 14 forms a limit between the two first ring plates 13 and the two sliding plates 12, ensuring that the first ring plates 13 move laterally and do not rotate, making the structure more stable). This design minimizes play and avoids frequent disassembly and reassembly of the basin, preventing abnormal wear and increased play. The two first round rods 15 move laterally away from each other within the elongated groove 20, causing the two locking blocks 16 to disengage from the through hole 19 and secure the assembly plate 18. As the drive mechanism continues to operate, the two first round rods 15 slide into the ends of the two elongated grooves 20 (the length of the assembly plate 18 can be adjusted according to the size of the basin, while the length of the base mechanism remains fixed. The sliding of the two first round rods 15 within the two elongated grooves 20 ensures adaptability to basins of different sizes, with support points located on the left and right sides of the basin). This provides long-distance support for the assembly plate 18, ensuring the stability of the basin. In the assembled state, the sidewall of the basin contacts the wall, forming support points. The first round rods 15 and locking blocks 16 apply a certain vertical support force to the basin and bind it to the wall.

[0037] In this invention, the locking block 16 at the end of the first round rod 15 engages with the through hole 19 on the assembly plate 18. Subsequently, the drive mechanism drives the sliding plate 12 and the first ring plate 13 to move away from each other on the elongated bottom groove 11, thereby causing the two sets of first round rods 15 and locking blocks 16 to move away from each other. This expands the support range on the one hand, and on the other hand, the first round rod 15 carries the locking block 16 from the middle through hole 19 to the elongated groove 20, thereby locking the movement and avoiding the problem of inconvenient operation caused by bolt locking. Furthermore, by locking the assembly plates 18 of different lengths through the first round rod 15 and locking block 16 inside the fixed-length base mechanism, the applicability of the equipment is further enhanced.

[0038] As a further embodiment of the present invention, the driving mechanism includes a first gear 23 rotatably disposed in the center of the elongated bottom groove 11, and first teeth 24 are provided on the side walls of the two slide plates 12 that are close to each other. The first gear 23 meshes with the first teeth 24 on the side walls of the two slide plates 12. A spring spring 25 is provided on the inner wall of the rear end of the first gear 23. One end of the spring spring 25 is fixedly connected to the first gear 23, and the other end is fixedly connected to the side wall of the elongated bottom groove 11.

[0039] When using this invention (during the transportation of the base mechanism, a disposable rope is needed to restrict the position of the two first round rods 15; the drive mechanism can be activated by simply cutting the rope during assembly), after the rope is cut, the spring 25's return force drives the first gear 23 to rotate. The rotation of the first gear 23 drives the first teeth 24 on the side wall of the slide plate 12, causing the two slide plates 12 to move towards both ends on the inner wall of the elongated bottom groove 11. The movement of the two slide plates 12 respectively drives the two first ring plates 13 to move away from each other, thereby allowing the first round rod 15 to move with the carrying block 16 into the elongated groove 20 of the assembly plate 18, thus locking the assembly plate 18 with the basin. When the first round rod 15 moves to the end of the elongated groove 20, the spring 25 will still have a small portion that has not recovered, thus always maintaining the locking force. This avoids the loosening that occurs during long-term use of the basin when using conventional bolt locking, which can cause the basin to wobble.

[0040] As a further embodiment of the present invention, a first spring 27 is sleeved on the outer wall of the first round rod 15 located between the first ring plate 13 and the locking block 16, and a second ring plate 28 is sleeved on the outer wall of the first round rod 15. One end of the first spring 27 is fixedly disposed on the side wall of the first ring plate 13, and the other end is fixedly disposed on the second ring plate 28.

[0041] During the use of this invention, when the locking block 16 is engaged in the through hole 19 of the assembly plate 18, the assembly plate 18 presses against the second ring plate 28, so that the first spring 27 on the first ring plate 13 always applies pressure to the second ring plate 28, so that the second ring plate 28 always presses against the assembly plate 18, thereby reducing the shaking of the assembly plate 18 and preventing the basin from shaking and falling off during use.

[0042] As a further embodiment of the present invention, a through hole 30 is provided in the center of the first ring plate 13, and a first round rod 15 is sleeved in the through hole 30. A second long round through groove 31 is provided on the long round bottom groove 11, and the first round rod 15 passes through the second long round through groove 31. A long round stepped groove 32 with the same center line as the second long round through groove 31 is provided at the rear end of the long round bottom plate 10, and the height of the upper side wall of the long round stepped groove 32 is far from the center line. A friction wheel 33 is coaxially provided at one end of the first round rod 15 that passes through the long round bottom plate 10. The friction wheel 33 is in contact with the lower side wall of the long round stepped groove 32. The friction wheel 33 is screwed to the first round rod 15. A 90-degree rotating groove 35 is provided on the side wall of the through hole 30. A limit key 36 is fixedly provided on the outer wall of the first round rod 15. The limit key 36 is inside the rotating groove 35.

[0043] When using this invention, as Figure 2 and 3 As shown, when the first round rod 15 moves with the first ring plate 13, it slides laterally within the second elongated through groove 31. This causes the friction wheel 33 to rotate due to friction from the elongated stepped groove 32 as the first round rod 15 moves laterally. Consequently, the first round rod 15 rotates, causing the limiting key 36 to rotate 90 degrees within the rotating groove 35 as the first round rod 15 rotates (furthermore, the friction wheel 33 rotates due to friction with the elongated stepped groove 32). The first round rod 15 stops rotating, and the friction wheel 33 rotates around it, pulling the first round rod 15 towards the end closer to the elongated bottom plate 10. The rod 15 moves backward within the through hole 30 of the first ring plate 13, thereby pulling the assembly plate 18 closer to the first ring plate 13. This causes the pressure of the first spring 27 to increase, thereby increasing the clamping force on the assembly plate 18 and preventing the basin from shaking during use. This causes the locking block 16 to rotate on the outer wall of the elongated groove 20 of the assembly plate 18, resulting in a 90-degree angle between the transverse long axis of the locking block 16 and the center line of the elongated groove 20. This allows the locking block 16 to have a larger overlap surface with the assembly plate 18 in the vertical direction, preventing the assembly plate 18 from experiencing torsional force around the end of the first round rod 15, which could cause the basin to rotate.

[0044] As a further embodiment of the present invention, two water pipe connectors 43 are symmetrically fixed on the front end face of the elongated bottom plate 10 about the front-rear central axis. Locking bolts 44 are rotatably connected to the water pipe connectors 43. The outer wall of the locking bolts 44 is provided with second teeth 45. The front end faces of the two sliding plates 12 are each fixedly provided with second racks 46 that mesh with the locking bolts 44. Two basin water inlet pipes 47 are provided on the assembly plate 18. The rear threads of the two basin water inlet pipes 47 are respectively engaged with the locking bolts 44. The basin water inlet pipes 47 and the assembly plate 18 are axially slidably connected. A second spring 48 is sleeved on the outer wall of the basin water inlet pipes 47. One end of the second spring 48 is fixed to the assembly plate 18, and the other end is fixed to the basin water inlet pipes 47.

[0045] When the present invention is used, when the assembly plate 18 is connected to the elongated bottom plate 10, the basin water inlet pipe 47 will connect with the water pipe connector 43. When the slide plate 12 slides laterally, it will drive the second tooth 45 on the locking bolt 44 through the second rack 46 to lock the basin water inlet pipe 47 (the initial movement force of the spring 25 is large, so there will be no problem with locking. Secondly, the action of the second spring 48 can make the basin water inlet pipe 47 and the water pipe connector 43 flexibly connect, avoiding the problem of collision damage).

[0046] As a further embodiment of the present invention, a support plate 50 that can be cast into concrete for support is fixedly provided on the rear section of the front end face of the elongated oval base plate 10.
