Description

Technical Field

[0001] This utility model relates to the field of architectural hardware, specifically a wall-mounted bathroom fixture installation component with pre-tightening function. Background Technology

[0002] Wall-mounted bathroom fixture installation components are concealed support structures used to fix bathroom fixtures such as hanging baskets, toilets, and washbasins. Their function is to actively eliminate gaps and enhance stability during installation through pre-tightening mechanisms, such as bolts or spring devices, to ensure that the fixture fits tightly against the wall. At the same time, they distribute the load to reduce the risk of loosening and improve the safety and seismic performance of long-term use.

[0003] In existing technologies, wall-mounted bathroom fixture installation components can ensure a tight fit between the fixture and the wall through a pre-tightening force adjustment mechanism, while distributing the load to reduce the risk of loosening. When installing bathroom hanging baskets, expansion bolts are usually used to fix the baskets to ensure they do not easily slip off. While a single expansion bolt can effectively pre-tighten and fix the basket, over time, the bolt connection may loosen or wobble due to long-term stress, causing the bathroom hanging basket to loosen and wobble simultaneously, thus posing a risk of slipping off. Utility Model Content

[0004] To overcome the shortcomings of existing technology, although a single expansion bolt can effectively pre-tighten and fix the bathroom hanging basket, the bolt connection may loosen and shake over time due to long-term stress, causing the bathroom hanging basket to loosen and shake simultaneously, thus posing a risk of the bathroom hanging basket slipping. This utility model proposes a wall-mounted bathroom fixture installation component with a pre-tightening function.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a wall-mounted bathroom fixture installation component with pre-tightening function, including a shower basket, an extension rod rotatably connected to the inner cavity of the shower basket, a screw fixedly connected to one end of the extension rod, an expansion sleeve threadedly connected to the surface of the screw, an expansion head fixedly connected to one end of the screw, a connecting side plate threadedly connected to the surface of the screw, and a limit mechanism provided on the surface of the connecting side plate; The limiting mechanism includes a ratchet, the inner cavity of which is fixedly connected to the surface of the extension rod. A connecting rod is fixedly connected to one side of the connecting side plate. A pawl is rotatably connected to the surface of the connecting rod. The surface of the pawl meshes with the surface of the ratchet. A mounting block is fixedly connected to one side of the pawl. A reinforcing component is provided on one side of the mounting block.

[0006] Preferably, the reinforcement component includes a connecting plate, one side of which is fixedly connected to one side of a connecting side plate, and a mounting plate is fixedly connected to one side of the connecting side plate. A threaded rod is rotatably connected to the inner cavity of the mounting plate, one end of which is rotatably connected to one end of the connecting plate. A movable plate is threadedly connected to the surface of the threaded rod, and one side of the movable plate is movably connected to one side of the mounting block.

[0007] Preferably, one side of the connecting side plate is movably engaged with a limiting post, and the surface of the limiting post is movably connected to the surface of the pawl.

[0008] Preferably, a limiting rod is rotatably connected to one side of the connecting plate, one end of the limiting rod is fixedly connected to one side of the mounting plate, and the surface of the limiting rod is slidably connected to the inner cavity of the moving plate.

[0009] Preferably, a sliding groove is provided on one side of the connecting side plate, and a sliding block is fixedly connected to one side of the moving plate, with the surface of the sliding block slidably connected to the inner cavity of the sliding groove.

[0010] Preferably, a locking block is fixedly connected to the bottom of the limiting post, and a locking groove is opened on one side of the connecting side plate, and the surface of the locking block is movably locked with the inner cavity of the locking groove.

[0011] Preferably, a protective shell is movably engaged on one side of the ratchet, and one side of the protective shell is fitted onto the surface of the extension rod.

[0012] The advantages of this utility model are: This invention uses an extension rod and a screw to fix the shower basket to the wall. Continuous rotation of the extension rod applies a pre-tightening force to the screw, while the engagement of a ratchet and pawl limits the extension rod's movement, preventing counter-clockwise rotation. A reinforcing component further pushes the pawl, ensuring a tighter engagement between the pawl and ratchet. The limiting mechanism prevents reverse rotation of the extension rod, allowing the pre-tightening force applied to the screw to be maintained for a longer period. This ensures the extension rod can permanently secure the shower basket, preventing loosening and wobbling. This solves the problem that while expansion bolts can effectively pre-tighten and fix the shower basket, they can loosen and wobble over time due to prolonged stress, potentially causing the basket to slip and fall.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0017] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail. This application discloses a wall-mounted bathroom fixture installation component with a pre-tightening function. (Refer to...) Figure 1 and Figure 2A wall-mounted bathroom fixture installation component with pre-tightening function includes a shower basket 1, an extension rod 2 rotatably connected to the inner cavity of the shower basket 1, a screw 14 fixedly connected to one end of the extension rod 2, an expansion sleeve 3 threadedly connected to the surface of the screw 14, an expansion head 13 fixedly connected to one end of the screw 14, a connecting side plate 12 threadedly connected to the surface of the screw 14, and a limit mechanism 4 provided on the surface of the connecting side plate 12. The limiting mechanism 4 includes a ratchet 401, the inner cavity of which is fixedly connected to the surface of the extension rod 2. A connecting rod 402 is fixedly connected to one side of the connecting side plate 12. A pawl 403 is rotatably connected to the surface of the connecting rod 402. The surface of the pawl 403 meshes with the surface of the ratchet 401. A mounting block 404 is fixedly connected to one side of the pawl 403. A reinforcing component 405 is provided on one side of the mounting block 404.

[0018] In daily life, people can place bath products inside the shower basket 1 for easy access. When installing the shower basket 1, first drill a hole in the wall, then place the shower basket 1 onto the surface of the extension rod 2, insert the screw 14 into the wall, and simultaneously use a tool to rotate the extension rod 2 clockwise. This rotation causes the screw 14 and expansion head 13 to move upwards. As the expansion head 13 moves, it expands the expansion sleeve 3, allowing it to embed into the wall and thus securing the shower basket 1. After securing, continue rotating the extension rod 2 clockwise to apply a pre-tightening force to the screw 14, ensuring a tighter fit between the expansion sleeve 3 and the wall. Since there are two extension rods 2, two expansion sleeves 3, two expansion heads 13, and two screws 14 with identical structures, further details are omitted here. (Connecting side...) Plate 12 is connected to screw 14, and connecting side plate 12 can be connected to the wall by bolts or other means. Extension rod 2 can provide installation and connection for ratchet 401. Connecting side plate 12 provides connection for pawl 403 through connection with connecting rod 402. When people tighten extension rod 2, pawl 403 and ratchet 401 can mesh with each other. The meshing of pawl 403 and ratchet 401 makes it difficult for extension rod 2 to rotate counterclockwise, so that extension rod 2 can maintain a pre-tight state for a long time. Pawl 403 is connected to mounting block 404. People can operate reinforcement component 405 to push mounting block 404, so that pawl 403 and ratchet 401 mesh more tightly. At the same time, there are two limiting mechanisms 4, and the two limiting mechanisms 4 have the same structure, so they will not be described in detail here.

[0019] Reference Figure 3 and Figure 4The reinforcement component 405 includes a connecting plate 4051, one side of which is fixedly connected to one side of a connecting side plate 12. A mounting plate 4052 is fixedly connected to one side of the connecting side plate 12. A threaded rod 4053 is rotatably connected to the inner cavity of the mounting plate 4052. One end of the threaded rod 4053 is rotatably connected to one end of the connecting plate 4051. A movable plate 4054 is threadedly connected to the surface of the threaded rod 4053. One side of the movable plate 4054 is movably connected to one side of the mounting block 404. The connecting side plate 12 provides installation and connection for the connecting plate 4051 and the mounting plate 4052. Both extension rods 2 and 4053 are connected to the threaded rod 4053. The threaded rod 4053 can also provide a mounting function for the movable plate 4054. The threaded rod 4053 can be continuously rotated, and the movable plate 4054 can be moved along the surface of the threaded rod 4053. This causes the movable plate 4054 to move to one side of the mounting block 404 and fit against the mounting block 404. By continuously rotating the threaded rod 4053, the movable plate 4054 pushes the mounting block 404. This pushes the mounting block 404, making the engagement between the pawl 403 and the ratchet 401 more stable, thus allowing the preload of the extension rod 2 to be maintained for a long time.

[0020] Reference Figure 4 and Figure 6 One side of the connecting side plate 12 is movably engaged with a limiting post 9. The surface of the limiting post 9 is movably connected to the surface of the pawl 403. The connecting side plate 12 can serve as a mounting and connecting unit for the limiting post 9. After the pawl 403 and the ratchet 401 are engaged, the limiting post 9 can be connected to the connecting side plate 12, and the pawl 403 can be limited by the limiting post 9. The setting of the limiting post 9 can make the pawl 403 itself less prone to displacement and can better complete the engagement with the ratchet 401.

[0021] Reference Figure 4 A limiting rod 8 is rotatably connected to one side of the connecting plate 4051. One end of the limiting rod 8 is fixedly connected to one side of the mounting plate 4052. The surface of the limiting rod 8 is slidably connected to the inner cavity of the moving plate 4054. Both the connecting plate 4051 and the mounting plate 4052 are connected to the limiting rod 8. The limiting rod 8 can provide a limiting function for the moving plate 4054. When the moving plate 4054 moves, the setting of the limiting rod 8 can make it less likely for the moving plate 4054 to deviate or shake while moving, so that the moving plate 4054 can push the mounting block 404 more smoothly.

[0022] Reference Figure 5 and Figure 6A sliding groove 6 is provided on one side of the connecting side plate 12, and a sliding block 7 is fixedly connected to one side of the moving plate 4054. The surface of the sliding block 7 is slidably connected to the inner cavity of the sliding groove 6. The moving plate 4054 can provide installation and connection for the sliding block 7. By providing a sliding groove 6 on one side of the connecting side plate 12, the sliding block 7 can slide inside the sliding groove 6. The setting of the sliding block 7 can make the moving plate 4054 more stable when moving and less prone to displacement.

[0023] Reference Figure 6 and Figure 7 The bottom of the limiting post 9 is fixedly connected to a locking block 11, and a locking groove 10 is opened on one side of the connecting side plate 12. The surface of the locking block 11 is movably locked with the inner cavity of the locking groove 10. The limiting post 9 is connected to the locking block 11. At the same time, by opening the locking groove 10 on one side of the connecting side plate 12, the locking block 11 can be movably locked with the connecting side plate 12. People can decide whether to limit the pawl 403 according to the situation based on the connection relationship between the locking block 11 and the connecting side plate 12. At the same time, it is more convenient and smoother to disassemble the limiting post 9 when necessary.

[0024] Reference Figure 2 and Figure 3 A protective shell 5 is movably engaged on one side of the ratchet 401. One side of the protective shell 5 is fitted onto the surface of the extension rod 2. The ratchet 401 can be connected to the protective shell 5. The protective shell 5 can protect the entire limiting mechanism 4, making it difficult for moisture inside the bathroom to directly enter the interior of the limiting mechanism 4. This prevents the interior of the protective shell 5 from getting damp or rusting, thus affecting the normal use of the limiting mechanism 4.

[0025] Working Principle: Before using this device, a hole is drilled in the wall, and the shower basket 1 is fitted onto the surface of the extension rod 2. The screw 14 is then inserted into the wall, and the extension rod 2 is rotated clockwise. This rotation causes the screw 14 and expansion head 13 to move upwards, expanding the expansion sleeve 3 and embedding it into the wall, thus securing the shower basket 1. After securing, the extension rod 2 is rotated clockwise to apply a pre-tightening force to the screw 14, ensuring a tighter fit between the expansion sleeve 3 and the wall. Once the extension rod 2 is tightened, the pawl 403 engages with the ratchet 401, preventing counter-clockwise rotation and maintaining a pre-tightened state. By continuously rotating the threaded rod 4053, the moving plate 4054 moves along the surface of the threaded rod 4053, causing the moving plate 4054 to move to one side of the mounting block 404 and fit against the mounting block 404. By continuously rotating the threaded rod 4053, the moving plate 4054 pushes the mounting block 404, and the pushing of the mounting block 404 makes the engagement between the pawl 403 and the ratchet 401 more stable, thereby maintaining the preload of the extension rod 2 for a long time. The setting of the limiting mechanism 4 makes it difficult for the extension rod 2 to rotate in the opposite direction, so that after the extension rod 2 applies the preload to the screw 14, the preload applied by the extension rod 2 can be maintained for a longer time, thereby allowing the extension rod 2 to play a fixed role for the shower basket 1 for a long time and making the shower basket 1 less prone to loosening and shaking.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
