Description

Technical Field

[0001] This invention relates to the field of bathroom product technology, and more specifically, to a countertop mounting bracket. Background Technology

[0002] Traditional faucet installation requires threaded mounting tubes to be passed through mounting holes in the countertop, and then a nut compatible with the threaded mounting tubes is screwed in from under the countertop. The nut is then rotated to press against the bottom of the countertop, thus securing the faucet. However, the limited space under the countertop makes it difficult to rotate the nut, and installers need to squat down continuously, which is time-consuming and laborious. Therefore, more and more products are adopting countertop mounting structures. For example, Chinese patent CN206986978U discloses a faucet fixing and mounting device, including a fixing device, a screw connected to the fixing device, and a fixing block mounted on the screw. During installation, the fixing block retracts inward to pass through the mounting hole, placing the fixing base on the top surface of the countertop. Then, rotating the screw drives the fixing block outward, and a limiting structure allows the fixed block to move to the bottom surface of the countertop after unfolding, thus cooperating with the fixing device to clamp the worktable. However, due to the size of the mounting hole, the two screws need to be installed inside the fixing device, resulting in a small through hole in the fixing device. This limits the installation space for the pipe fittings and makes it difficult to install the pipe fittings and faucets, especially for faucets with threaded pipes, which can easily lead to assembly problems. Summary of the Invention

[0003] This invention discloses a platform mounting bracket, which aims to improve the problem that the existing platform mounting structure has small through holes, which is not conducive to the installation of pipe fittings.

[0004] The present invention adopts the following solution: A tabletop mounting bracket includes a main body, a movable base, and a nut. The main body has a through hole extending axially, and multiple sliding grooves are provided along the side wall of the through hole. The movable base and the nut are both fitted into the through hole and are circumferentially limited by the sliding grooves. At least two rotatable flip blocks are provided along the side wall of the movable base. The flip blocks are configured to flip outward under the action of gravity. The nut is located below the movable base and has an internal thread for screwing into a threaded tube. The threaded tube is operably rotated to move the nut against the movable base upward and to make the flip blocks abut against the bottom surface of the tabletop.

[0005] As a further improvement, a fixed cover is fitted on the top of the main body, and multiple rotating teeth are provided along the inner wall of the fixed cover. A pawl that engages with the rotating teeth is provided on the top of the main body. When the flipping block is pressed against the bottom surface of the table, the main body drives the pawl to slide relative to the rotating teeth under the action of the nut to emit a prompt sound.

[0006] As a further improvement, the rotating tooth has a guide surface and a stop surface, the guide surface is arranged obliquely along the locking direction, the stop surface is arranged along the unlocking direction, and the pawl is arranged to slide only along the direction of the guide surface.

[0007] As a further improvement, at least one guide surface is provided with a protrusion to restrict the sliding of the pawl, so that the pawl is restricted between the protrusion and the stop surface.

[0008] As a further improvement, a decorative cover is fitted around the outer periphery of the fixed cover, a first locking part is provided on the outer periphery of the fixed cover, and a second locking part is provided on the inner wall of the decorative cover. The first locking part and the second locking part engage with each other to limit the decorative cover along the axial direction.

[0009] As a further improvement, the decorative cover is provided with mounting holes for fitting to the outer wall of the body to be installed.

[0010] As a further improvement, the outer wall of the nut is provided with a limiting part corresponding to each of the slide grooves. The limiting part extends into the slide groove to limit the nut in the circumferential direction. The movable seat is provided with a mounting part. The flipping block is hinged to the mounting part. The mounting part extends into the slide groove to limit the movable seat in the circumferential direction.

[0011] As a further improvement, the mounting part is provided with a first mounting hole, and the flipping block is provided with a second mounting hole. The first mounting hole and the second mounting hole are connected via a rotating shaft so that the flipping block can be flipped relative to the movable seat.

[0012] As a further improvement, the movable seat is provided with an outwardly inclined elastic part corresponding to the flipping block, and the flipping block is configured to squeeze the elastic part to retract inward, or to flip outward under the action of the elastic part.

[0013] As a further improvement, the movable seat has a through hole through which the threaded tube passes, and multiple limiting ribs extend vertically along the wall of the through hole to reduce the gap between the inner wall of the through hole and the outer wall of the threaded tube.

[0014] By adopting the above technical solution, the present invention can achieve the following technical effects: 1. This application simplifies the structure for driving the unfolding of the flip block by incorporating a rotatable tilting block that retracts upon entering the mounting hole and unfolds downwards under gravity after exiting the hole. This reduces the space occupied by components in the through-hole. Compared to existing technologies, the unfolding of the tilting block does not require a screw, saving space within the through-hole and ensuring sufficient space for pipe installation. Furthermore, the simple structure and fewer parts reduce costs and enhance market competitiveness.

[0015] 2. When the flip block is pressed against the bottom surface of the table, the main body, under the action of the nut, drives the pawl to slide relative to the rotating teeth on the fixed cover, making a "click-click-click" sound to indicate that it has been installed in place. This allows the installer to understand the installation status without having to go under the table to observe, thus further facilitating the installation.

[0016] 3. When the flip block flips downwards, its bottom abuts against the mounting part on the movable base to control the angle of the flip block flipping downwards, ensuring that the top of the flip block is higher than the top of the movable base, and can withstand the clamping force when it abuts against the table surface, so as to ensure the stability when locking and avoid the problem of the mounting bracket loosening.

[0017] 4. The movable seat has an outwardly tilting elastic part corresponding to the flipping block to further ensure that the flipping block can flip outward and prevent the flipping block from failing to flip automatically. Attached Figure Description

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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 a part of the embodiments of the present invention, not all of them. 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. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to represent selected embodiments of the invention. 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.

The terms “first,” “second,” etc., are only used to distinguish different objects and should not be construed as indicating or implying relative importance or the quantity, specific order, or primary or secondary relationship of the indicated technical features. The term “several” means one or more, and “multiple” means two or more, unless otherwise explicitly specified. Example

[0023] Combination Figures 1 to 15 This embodiment provides a platform mounting bracket, including a main body 1, a movable seat 2, and a nut 3. The main body 1 has a through hole 11 that extends axially, and a plurality of sliding grooves 12 are provided on the side wall of the through hole 11. The movable seat 2 and the nut 3 are both fitted into the through hole 11 and are limited circumferentially by the sliding grooves 12. At least two rotatable flip blocks 21 are provided on the side wall of the movable seat 2. The flip blocks 21 are configured to flip outward under the action of gravity. The nut 3 is located below the movable seat 2 and is provided with an internal thread 31 for screwing into a threaded tube 6. The threaded tube 6 is rotated in an operable manner to make the nut 3 abut against the movable seat 2 and move upward, and to make the flip blocks 21 abut against the bottom surface of the platform.

[0024] During installation, first screw nut 3 into threaded tube 6, then insert threaded tube 6 with mounting bracket on the table into the mounting hole. Due to the size of the mounting hole, the flipping block 21 will retract inward. Once it is under the table surface, the flipping block 21 can flip downward and unfold under gravity. Then, hold the main body 1 with one hand and rotate the threaded tube 6 with the other, causing nut 3 to move upward along the slide groove 12, pressing against the moving seat 2 until the flipping block 21 abuts against the bottom surface of the table surface, thus fixing the main body 1 and the threaded tube 6. In other words, the faucet mounted on or connected to the threaded tube 6 is fixed. In one method, the slide groove 12 is connected to the bottom surface of the main body 1. During disassembly, by rotating the threaded tube 6 in the opposite direction, nut 3 descends until it detaches from the threaded tube 6, allowing nut 3 to detach from the threaded tube 6 and the moving seat 2 to fall directly. This allows both assembly and disassembly to be performed on the table. In another embodiment, to avoid losing parts, after the nut 3 is detached from the threaded tube 6, it is restricted by the slide groove 12 and falls to the bottom of the slide groove 12. When disassembling, it is necessary to manually flip the flip block 21 upward and retract it, and then push it upward out of the mounting hole.

[0025] It should be noted that in this embodiment, a rotatable flip block 21 is provided, which retracts when entering the mounting hole and flips downward under gravity after exiting the mounting hole. This simplifies the structure used to drive the flip block 21 to unfold, thereby reducing the space occupied by components in the through hole 11. Compared with the prior art, the unfolding of the flip block 21 does not require a screw, saving space in the through hole 11 so that the space in the through hole 11 can meet the installation of the pipe fitting. In addition, the structure is simple and has fewer parts, which can save costs and improve market competitiveness.

[0026] In a preferred embodiment, a fixing cover 4 is fitted onto the top of the main body 1. Multiple rotating teeth 41 are provided along the inner wall of the fixing cover 4. A pawl 13, engaging with the rotating teeth 41, is provided on the top of the main body 1. When the flipping block 21 abuts against the bottom surface of the table, the main body 1, under the action of the nut 3, drives the pawl 13 to slide relative to the rotating teeth 41, thus emitting a warning sound. For example, the outer wall of the nut 3 is provided with a limiting part 32 corresponding to each slide groove 12. The limiting part 32 extends into the slide groove 12 to limit the nut 3 circumferentially. The movable seat 2 is provided with a mounting part 22. The flipping block 21 is hinged to the mounting part 22, which extends into the slide groove 12 to limit the movable seat 2 circumferentially. The nut 3 and the movable seat 2 can be inserted obliquely along the through hole 11, so that the limiting part 32 and the mounting part 22 extend into the slide groove 12, reducing the deformation of the through hole 11 during assembly and ensuring the insertion force of the nut 3 and the movable seat 2.

[0027] Specifically, when the flipping block 21 has not yet come into contact with the table surface, the nut 3 moves upward and the limiting part 32 has a small abutting force against the side wall of the slide groove 12, so it will not cause the pawl 13 on the main body 1 to slide relative to the rotating tooth 41. After the flipping block 21 comes into contact with the table surface, the threaded tube 6 continues to rotate and the nut 3 can no longer move upward. At this time, the limiting part 32 has a large abutting force against the side wall of the slide groove 12, which drives the pawl 13 on the main body 1 to slide relative to the rotating tooth 41, so as to make a "click-click-click" prompt sound, indicating that it has been installed in place, so that the installer can understand the installation status without having to go to the bottom of the table to observe, which further facilitates the installation.

[0028] Furthermore, the rotating tooth 41 has a guide surface 411 and a stop surface 412. The guide surface 411 is arranged at an angle along the locking direction, and the stop surface 412 is arranged along the unlocking direction. The pawl 13 is configured to slide only along the direction of the guide surface 411. The guide surface 411 has a small slope, while the stop surface 412 has a large slope. The pawl 13 can only slide relative to the rotating tooth 41 in the locking direction and cannot slide relative to the rotating tooth 41 in the unlocking direction. This ensures that the main body 1 will not rotate relative to the fixed cover 4 in any state during unlocking, thus guaranteeing a smooth unlocking process.

[0029] In one embodiment, at least one guide surface 411 is provided with a protrusion 413 for limiting the sliding of the pawl 13, so that the pawl 13 is restricted between the protrusion 413 and the stop surface 412. During installation, the pawl 13 is engaged on several rotating teeth 41 in front of the protrusion 413, so that the pawl 13 is continuously rotated when locked, and there is no slippage state that continuously emits a beeping sound. After the pawl 13 slides past several rotating teeth 41, it is restricted by the protrusion 413 and stops, so as to remain in the locked state.

[0030] Based on the above embodiments, in an optional embodiment of the present invention, a decorative cover 5 is fitted around the outer periphery of the fixed cover 4. The fixed cover 4 has a first locking portion 42 on its outer periphery, and the decorative cover 5 has a second locking portion 51 on its inner wall. The first locking portion 42 and the second locking portion 51 engage with each other to limit the axial movement of the decorative cover 5. The decorative cover 5 can conceal the structure on the fixed cover 4, making the faucet's appearance more aesthetically pleasing and simple. For example, the first locking portion 42 protrudes along the outer periphery of the fixed cover 4 and has an arc-shaped cross-section; the second locking portion 51 is a groove along the inner wall of the decorative cover 5. However, this is not a limitation and is not specifically restricted.

[0031] Preferably, the decorative cover 5 is provided with a mounting hole 52 for fitting the outer wall of the body 7 to be installed, so that the body 7 to be installed can be inserted into the mounting hole 52 without the need for other fixing structures.

[0032] Based on the above embodiments, in an optional embodiment of the present invention, the mounting part 22 is provided with a first mounting hole, and the flipping block 21 is provided with a second mounting hole. The first mounting hole and the second mounting hole are connected via a rotating shaft 23, so that the flipping block 21 can be flipped relative to the movable seat 2. When the flipping block 21 flips downwards, its bottom abuts against the mounting part 22 to control the angle of downward flipping of the flipping block 21, ensuring that the top of the flipping block 21 is higher than the top of the movable seat 2, and that it can withstand the clamping force when abutting against the table surface, thus ensuring stability during locking and preventing the mounting bracket from loosening.

[0033] In another embodiment, the movable base 2 is provided with an outwardly inclined elastic portion 24 corresponding to the flipping block 21. The flipping block 21 is configured to compress the elastic portion 24 to retract inward, or to flip outward under the action of the elastic portion 24. The provision of the elastic portion 24 further ensures that the flipping block 21 can flip outward. The flipping block 21 automatically flips under the dual protection of the elastic force of the elastic portion 24 and the gravity of the flipping block 21, to prevent the flipping block 21 from failing to flip. For example, the movable base 2 is a plastic part, and the elastic portion 24 is integrally formed with the movable base 2, so that the elastic portion 24 has a certain elasticity and can be fixedly connected to the movable base 2, reducing the number of parts.

[0034] In other embodiments, the movable seat 2 has a through hole 25 through which the threaded tube 6 passes. Multiple limiting ribs 251 extend vertically along the wall of the through hole 25 to reduce the gap between the inner wall of the through hole 25 and the outer wall of the threaded tube 6, so as to avoid the center of the movable seat 2 from shifting, which would cause the position of the flipping blocks 21 on both sides to deviate too much, resulting in an uneven clamping force between the flipping blocks 21 and the main body 1.

[0035] The above are merely preferred embodiments of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions that fall within the scope of the present invention are within the scope of protection of the present invention.
