Description

Technical Field

[0001] The utility model relates to the technical field of bathroom product production, in particular to a quick disassembly and assembly component under a faucet table. Background Art

[0002] When the existing faucet is installed on the countertop, the threaded tube of the faucet body is placed under the countertop, and then the threaded tube of the faucet body is screwed and locked by a nut, so that the faucet body is placed upright on the countertop. The existing method has some installation problems during the installation process, specifically: the space under the countertop is small, the installer needs to drill under the countertop to rotate, and the nut needs to be screwed from the end of the threaded tube to the other end, which is not only difficult to apply force for assembly, but also difficult to observe whether the assembly is stable, and the effect and efficiency of the entire installation are low;

[0003] For this reason, industry personnel have developed a quick installation kit to reduce the number of turns of the threaded lock, so as to achieve the function of quick assembly, such as: the name of the Chinese utility model patent is: a faucet quick installation and quick release device, and the patent publication number is: CN216130256U. It clamps the screw pipe at the end of the faucet body through two locking blocks arranged on the base to achieve the effect of quick assembly, but there are also certain shortcomings: for example, the cold and hot water inlet pipes and the pull-out pipe cannot be passed through and installed from the countertop downward; the existing faucet is generally connected with at least two water inlet hoses (i.e., the cold and hot water inlet pipes; if it is a faucet with a pull-out function, it is connected with at least four hoses), and the other end of the cold and hot water inlet hoses is equipped with a joint nut. Due to the excessive size of the joint nut, it is difficult to pass through the quick installation and quick release device; the reason is that: the inner diameter of the existing conventional faucet body (screw pipe) is only 30.5mm, and the quick installation and quick release device matched with the outer wall of the screw pipe can only be slightly larger than the screw pipe. (If it is too large, the clamping bearing capacity of the two locking blocks will be poor and they cannot be clamped stably), and due to the limitation of the movement trajectory of the two locking blocks, it is impossible to open a clearance hole, so the diameter of the hole through which the cold and hot water inlet pipes pass in the quick-install and quick-release device is no more than 35mm; however, the outer size of the joint nut on the existing water inlet hose is 25.5mm, which causes the joint nuts on the cold and hot water inlet hoses to interfere with each other and cannot pass through from the front; for this reason, one water inlet hose can only be sealed and screwed to the faucet body first, and then the other water inlet hose is reversely passed through the quick-install and quick-release device from the bottom of the countertop, and then extended into the inside of the faucet body, and finally the water inlet hose (one end with the joint nut) is held and rotated, and forced to rotate by torque (that is, relying on the torque of the hose itself to achieve spiral rotation) so that the water inlet hose is assembled with the faucet body. This process is difficult to install (it requires long-term work under the counter), time-consuming and labor-intensive, and the sealing effect is poor after screwing, and the service life of the water inlet hose is also greatly reduced;

[0004] In summary, the existing quick installation components need to be further improved and upgraded to meet the needs of quick installation. Utility Model Content

[0037] See also Figure 1-2 and Fig. 9 The embodiment of the present invention is a faucet under-table quick disassembly assembly, which is used to fix the faucet on the table, that is, the faucet body 6 is connected to a screw tube 7, and after the screw tube 7 passes through the table, the quick disassembly assembly is sleeved on the outer wall of the screw tube 7, and then the screw tube 7 is rotated to embrace, so that the faucet body 6 is stably installed on the table 8;

[0038] The quick disassembly assembly of this embodiment comprises: a base 1, an embracing member 2, a limiting body 3 and a first elastic member 10;

[0039] See also Figure 1-4 , base 1, which has the shape of a grippable stud; a through hole 11, an avoidance channel 12 and a stepped platform 13 for the movement of the embracing member 2 are provided in the base 1; the through hole 11 here is opened along the axial direction and is used for the cold and hot water inlet pipes, drawing pipes and other pipe bodies to pass through; in addition, an avoidance channel 12 is formed on the inner wall of the through hole 11, which is also opened along the axial direction of the base 1. This embodiment is illustrated by taking a semicircular cross-sectional shape as an example, and the radius of the avoidance channel 12 is greater than the radius of the water inlet pipe 9, so that when the water inlet pipe 9 abuts against the avoidance channel 12, half or half of the water inlet pipe 9 is located in the avoidance channel 12 from the cross-section, and the other half is located in the through hole 11, so that multiple water inlet pipes 9 can be smoothly penetrated; in this way, the cold and hot water pipes can be directly installed before the faucet leaves the factory, and the user does not need to install it by himself later, which reduces the difficulty of installation;

[0040] Moreover, a stepped platform 13 is formed on the end of the base 1, on which the engaging piece 2 is installed and enables the engaging piece 2 to translate radially along the stepped platform 13; a threaded portion 111 is formed on the inner wall surface of the through hole 11 on the base 1 and relative to the stepped platform 13, and the threaded portion 111 cooperates with another threaded portion 21 on the engaging piece 2 to engage the screw tube 7, that is, the threads of the two threaded portions 111 and 21 are inserted into the outer wall of the screw tube 7.

[0041] An engaging member 2, which is mounted on the step platform 13 and has a passive inclined surface 22, wherein the passive inclined surface 22 is arranged opposite to the thread and is formed by the upper end surface of the engaging member 2 being inclined downward toward the outer peripheral surface;

[0042] The passive inclined surface 22 of the engaging member 2 is pressed by the positioning body 3 so that the engaging member 2 cooperates with the threaded portion 111 along the radial direction of the base 1 to clamp the threaded tube 7 of the faucet.

[0043] A limiting body 3, which is used to limit the embracing member 2 from leaving the step platform 13; the limiting body 3 in this embodiment is provided as a cover body, and has a through hole 36 and a clearance hole 35 corresponding to the through hole 11 in the middle, and the through hole 36 and the clearance hole 35 are both used for the water inlet pipe 9 to pass through;

[0044] The limiting body 3 is detachably mounted (covered) on the end of the base 1 and is formed with a pressing portion 30 that matches the passive inclined surface 22;

[0045] In addition, guide ribs 31 are formed on the inner wall of the limiting body 3 and hook portions 32 are formed along the outer periphery. The guide ribs 31 here cooperate with the guide grooves 15 so that the limiting body 3 can be smoothly and steadily displaced axially relative to the base 1; the guide grooves 15 of this embodiment are arranged axially along the outer periphery of the base 1, and are illustrated by three examples of interval arrangement; wherein, the guide ribs 31 of the limiting body 3 are installed corresponding to the guide grooves 15, so that the limiting body 3 can move axially along the base 1, and an axial activity space A is formed between the two, and the activity space A here refers to the distance between the limiting body 3 and the end face of the base 1, so that the pressing portion 30 of the limiting body 3 and the passive inclined surface 22 of the engaging member 2 no longer press against each other, and the engaging member 2 can be reset and translated to release the engaging clamping.

[0046] In addition, at least one hooking portion 32 (two hooking portions 32 are used as examples in this embodiment) is extended axially on the limiting body 3; the hooking portion 32 is hooked with the base 1 to limit the limiting body 3 from axially separating from the base 1, so that the entire limiting body 3 is sleeved on the base 1 to prevent the embracing member 2 from axially and radially separating from the stepped platform 13;

[0047] A surface on the limiter 3 that faces away from the base 1 is set as a friction surface 33. During actual installation, the friction surface 33 is in contact with the lower surface of the table 8 to increase the contact area or limit the reversal to prevent loosening. The friction surface 33 here can be a silicone surface, a continuous stepped surface, etc.

[0048] A first elastic member 10, which is integrally formed on the step platform 13, formed on a side of the embracing member 2 opposite to the step platform 13, or disposed between the embracing member 2 and the step platform 13, so as to drive the embracing member 2 to return to its original position when the pressure of the limiting body 3 is lost;

[0049] In this embodiment, the first elastic member 10 is configured as an elastic arm 10A (i.e., two elastic arms 10A) formed on the two side walls of the step platform 13, and the two elastic arms 10A extend toward the embracing member 2 respectively; and a corresponding connecting portion 23 is also extended on the embracing member 2 relative to the elastic arm 10A; wherein, the embracing member 2 moves radially along the base 1, and the connecting portion 23 presses against the elastic arm 10A, and when the embracing member 2 moves toward the center of the base 1, the elastic arm 10A presses against the elastic arm 10A and bends inward.

[0050] Of course, the first elastic member 10 can also be configured as a spring (not shown in the figure), which is installed on the two side walls of the step platform 13, and one end of the spring is against the embracing part 2, and the other end acts on the side wall of the step platform 13, that is, the embracing part 2 is compressed and deformed when moving toward the center of the base 1; the spring can also be installed in a groove (not shown in the figure) opened on the step platform 13, so that one end of the spring acts on the groove, and the other end acts on the embracing part 2.

[0051] In order to prevent the clasping member 2 from axially moving away from the step platform 13, an anti-slip structure is further provided in the present embodiment, which is used to limit the axial displacement of the clasping member 2 along the base 1 to ensure the smooth movement of the clasping member 2; the anti-slip structure includes a first limiting portion 25 and a second limiting portion 34 matched by inclined surfaces, wherein the first limiting portion 25 is formed on the clasping member 2 and extends axially toward the limiting body 3; the second limiting portion 34 is formed on the inner wall of the limiting body 3; wherein the inclined surface 341 of the second limiting portion 34 always acts on the inclined surface 251 of the first limiting portion 25 to limit the axial displacement of the clasping member 2 displacement, so that even if the limiting body 3 moves a certain distance in the axial direction, the cooperation of the two inclined surfaces 251 and 341 makes the first limiting portion 25 always act on the second limiting portion 34, that is, the engaging member 2 is axially pressed by the limiting body 3 in the form of the inclined surface, and cannot be axially displaced; in addition, the cooperation of the two inclined surfaces 251 and 341 can also be used to drive the engaging member 2 to move radially, that is to say, the engaging member 2 not only realizes radial movement through the cooperation of the passive inclined surface 22 and the pressing portion 30, but also through the two inclined surfaces 251 and 341, so that the engaging member 2 is more stable and smooth in radial movement;

[0052] Another form of anti-hair loss is: Figure 5-8As shown, a blocking arm 16 is extended from the side wall of the step platform 13, and a space B is formed between the blocking arm 16 and the table surface 8 of the step platform 13 for partially inserting the embracing member 2, so as to limit the axial movement of the embracing member 2 along the base 1 through the blocking arm 16 (in the present invention, an anti-detachment portion 24 is extended on the embracing member 2, which is placed in the insertion space B to avoid axial detachment); moreover, an assembly space C is formed between the elastic arm 10A and the blocking arm 16, and the assembly space C is gradually expanded toward the direction of the embracing member 2; wherein, the connecting portion 23 of the embracing member 2 is inserted into the assembly space C, and is guided by the side of the blocking arm 16 so that the connecting portion 23 is pressed against the elastic arm 10A, so that the elastic arm 10A can directly and quickly drive the embracing member 2 to reset.

[0053] In order to achieve smooth translation of the clasping member 2 on the step platform 13, a sliding structure 4 (such as Figure 2 , 5 As shown), it is used to guide the engaging member 2 to translate along the step platform 13; the sliding structure 4 includes a guide groove 41 and a slider portion 42; the slider portion 42 is formed on the bottom surface of the engaging member 2; the guide groove 41 is opened on the step platform 13, and is correspondingly arranged with the slider portion 42; wherein, the engaging member 2 cooperates with the guide groove 41 through the slider portion 42 to slide back and forth radially along the base 1.

[0054] In addition, in order to achieve faster resetting of the limit body 3 in the loose state, a second elastic component 5 is also provided, which is installed on the end face of the end of the base 1, and its two ends act on the base 1 and the limit body 3 respectively, so as to drive the limit body 3 to move axially in the direction away from the base 1 when the external force is lost.

[0055] (like Figure 1-9 Actual assembly process:

[0056] (1) placing the embracing member 2 on the step platform 13, and making the slider portion 42 on the lower surface of the embracing member 2 correspond to the guide groove 41 on the step platform 13, and move radially along the guide groove 41;

[0057] (2) At this time, the connecting portion 23 on the embracing member 2 directly corresponds to the elastic arm 10A installed on the side wall of the step platform 13 (or, the embracing member 2 is installed in the assembly space C formed by the elastic arm 10A and the blocking arm 16, and the anti-detachment portion 24 of the embracing member 2 enters the space B formed by the step platform 13 and the blocking arm 16; at this time, the connecting portion 23 abuts against the elastic arm 10A, and the anti-detachment portion 24 is restricted by the blocking arm 16 and cannot move axially).

[0058] (3) The second elastic member 5 (i.e., spring) is placed on the end surface of the base 1, and the limiting body 3 is correspondingly covered on the end of the base 1; in this process, the pressing portion 30 of the limiting body 3 corresponds to the passive inclined surface 22; it should be noted here that the pressing portion 30 is also an inclined surface, and the two form an inclined surface matching; the guide rib 31 on the limiting body 3 is installed corresponding to the guide groove 15 on the outer periphery of the base 1, so that the limiting body 3 can only move axially and cannot rotate circumferentially; at the same time, the second limiting portion 34 on the inner wall of the limiting body 3 also corresponds to the first limiting portion 251 of the embracing member 2, and the inclined surfaces 251 and 341 of the two cooperate; in addition, the hooking portion 32 is also buckled on the base 1 (or the base 1 and the embracing member 2), so that the limiting body 3 can move axially but will not separate from the base 1;

[0059] (4) After assembly, it is packaged and sold together with the faucet body 6.

[0060] When actually using the installation:

[0061] (1) Before leaving the factory, the cold and hot water inlet pipes 9, the pull-out pipe, etc. can be first passed through the screw pipe 7 and then screwed with the valve core seat inside the faucet body 6, so that the cold and hot water inlet pipes 9, the pull-out pipe, etc. are first connected to the faucet body 6.

[0062] (2) Insert the cold and hot water inlet pipes 9, the drawer pipe, etc. through the openings on the table top 8 and extend them into the lower surface of the table top 8;

[0063] (3) The quick disassembly assembly is sleeved on the outer periphery of the cold and hot water inlet pipes 9 and the pull-out pipe; in this process, the cold and hot water inlet pipes 9 have threaded joints respectively, and one of the water inlet pipes 9 (such as the cold water inlet pipe) is first passed through the through hole 11, and then the water inlet pipe 9 is accommodated or docked at the corresponding avoidance channel 12, and then the other water inlet pipe 9 (such as the hot water inlet pipe) is passed through. When passing through, it is only necessary to slightly tilt the threaded joint so that there is enough space B to directly pass through the through hole 11; then the pull-out pipe is inserted, and the cold and hot water inlet pipes 9 and the pull-out pipe can be passed through the quick disassembly assembly from the front;

[0064] (4) The quick disassembly assembly is directly sleeved upward from the free end of the screw tube 7 until the limiter 3 abuts against the lower surface of the table 8 or the gasket installed on the lower surface of the table 8; the base 1 is held upward and the second elastic member 5 is compressed, and the axial movable space A between the base 1 and the limiter 3 is compressed, so that the pressing portion 30 on the limiter 3 acts on the passive inclined surface 22 of the base 1, thereby driving the engaging member 2 to move toward the screw tube 7. At this time, the connecting portion 23 of the engaging member 2 acts on the elastic arm 10A (or is inserted into the assembly space C and abuts against the elastic arm 10A), and the elastic arm 10A bends and deforms inward, and the engaging member 2 is also linearly displaced by the action of the sliding structure 4 until it and the other half of the threaded portion 111 of the base 1 jointly engage with the outer wall of the screw tube 7, and the threaded portion 111 is clamped to the screw tube 7;

[0065] (5) Rotate a certain angle so that the threaded portion 111 matches the outer wall thread of the screw tube 7, thereby achieving quick installation;

[0066] (6) When it is necessary to disassemble, the base 1 is rotated in the opposite direction. Under the action of the second elastic member 5, the base 1 is driven to quickly loosen but not disengage relative to the limiting body 3, so that the pressing portion 30 of the limiting body 3 no longer applies force to the passive inclined surface 22; under the action of the elastic arm 10A, the engaging member 2 quickly retreats to the original state, disengaging from the engagement with the threaded tube 7, so that the entire quick-disassembly assembly can be quickly removed, which is convenient for maintenance and replacement; if it is a quick-install and quick-disassemble device in the prior art, it is necessary to remove the entire faucet body 6 in order to disassemble it, and the hose on the faucet body 6 needs to be removed, which makes disassembly difficult.

[0067] The utility model discloses a faucet under-table quick disassembly and assembly component, which has a simple structure, is easy to manufacture, easy to implement and has low cost, and solves the problems that the existing quick-disassembly and quick-assembly devices cannot pass the water inlet pipe with a threaded joint from the table top for installation, the installation is difficult and inefficient, and the installation stability is poor; the utility model improves the nut for quick disassembly and assembly under the table for the faucet, which not only realizes the quick assembly of the faucet, but also sleeves the quick-assembly component on the outer wall of the threaded tube, pushes the base and the limiting body axially, and makes the limiting body push the engaging part to move radially, cooperate with the threaded part to clamp (engage) the threaded tube, and then rotate a certain angle to complete the stable installation; when disassembling, the base is reversed, and the limiting body is no longer subjected to the force of the base. Through the action of the first elastic component, the threaded tube is loosened, so that it can be easily disassembled; not only that, an avoidance channel is opened axially at the through hole of the base, so that the water inlet pipe with the threaded joint can be allowed to be assembled during assembly. The pipe is installed through the front of the quick-disassembly assembly, that is, the water inlet pipe with a threaded joint (such as the cold water inlet pipe) is passed through the rear edge avoidance channel to be accommodated or placed, so that the remaining space of the through hole is sufficient for another water inlet pipe with a threaded joint (such as the hot water inlet pipe) to be smoothly passed through; even if it is a faucet with a pull-out function, the two water inlet pipes are respectively placed in the corresponding two avoidance channels, so that the space occupied by the two water inlet pipes in the through hole is reduced, and the pull-out pipe can be smoothly passed through and installed; on the basis of realizing quick disassembly and assembly, the new type can also penetrate and assemble the cold and hot water inlet pipes and the pull-out pipe from the countertop downward, breaking the tradition that the faucet and the hose cannot be assembled before leaving the factory for sale. The water inlet pipe, pull-out pipe, etc. can be directly sealed and assembled before leaving the factory, reducing the time for subsequent assembly by staff or users (assembly with professional tools before leaving the factory has better sealing), realizing true quick disassembly and assembly.

[0068] The above specification and description of the embodiments are used to explain the protection scope of the utility model, but do not constitute a limitation on the protection scope of the utility model.
