Description

Technical Field

[0001] The utility model relates to the technical field of bathroom product production, in particular to a component of a faucet which can be quickly disassembled and assembled. 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] To this end, industry personnel have developed a quick installation kit to reduce the number of turns of the thread 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, the patent publication number is: CN216130256U, which clamps the screw pipe at the end of the faucet body through two locking blocks set on the base to achieve the effect of quick assembly, but it also has certain shortcomings:

[0004] (1) The elastic member used to drive the two locking blocks to loosen and reset is prone to failure, which makes it very inconvenient to remove; the existing elastic member is arranged on the inner peripheral wall of the base and extends inward along the circumferential direction. Due to the size of the space, it cannot be set very large or thick, otherwise it will interfere with the movement of the locking block; such an elastic member has the function of driving the locking block to reset during initial use, but in actual use, that is, after a period of installation, the elastic member has already lost its reset ability due to elastic fatigue, and it also has to drive the tightly matched locking block to reset, and its actual use effect is poor; more importantly, a locking block must be equipped with at least two or more elastic members for reset, which increases the overall volume, occupies more space, and has high costs. It is difficult to assemble on some countertops equipped with special-shaped basins;

[0005] (2) The cold and hot water inlet pipes and the pull-out pipes cannot be passed through and installed from the countertop downwards; the existing faucets are generally connected to at least two water inlet hoses (i.e., the cold and hot water inlet pipes; if the faucet has a pull-out function, it is connected to at least four hoses), and the other ends of the cold and hot water inlet hoses are equipped with joint nuts. Since the joint nuts are too large, it is difficult to pass through the quick-install 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-install and quick-release device that cooperates with the outer wall of the screw pipe can only be slightly larger than the screw pipe (if it is too large, the clamping force of the two locking blocks is poor and cannot be stably clamped), and due to the movement trajectory restrictions 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 not large enough. Greater than 35mm; however, the outer dimension of the joint nut on the existing water inlet hose is 25.5mm, which causes interference between the joint nuts on the cold and hot water inlet hoses and prevents them from being passed through directly; for this reason, one water inlet hose can only be sealed and screwed to the faucet body first, passed through from above the countertop, and then the other water inlet hose is passed through the quick-install and quick-release device from below the countertop in the opposite direction, and then extended into the faucet body, and finally the water inlet hose (the end with the joint nut) is held and rotated, and the water inlet hose is forced to rotate by torque (i.e., the spiral rotation is achieved by relying on the torque of the hose itself) to connect the water inlet hose to 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 the screw is locked, and the service life of the water inlet hose is also greatly reduced;

[0006] In summary, the existing quick-disassembly and quick-assembly devices need to be further improved and upgraded to meet the actual needs of quick disassembly and assembly. Utility Model Content

[0013] The elastic arm is extended along the axial direction of the hollow tube toward the accommodating portion and cooperates with the sliding block in the radial direction to drive the sliding block to reset.

[0014] Furthermore, the accommodating portion forms a groove, which is opened along the axial direction of the hollow tube body, and the elastic arm protrudes from the bottom of the groove; the elastic arm acts on the sliding block to drive the sliding block to reset.

[0015] Furthermore, a passive portion extends from the bottom of the sliding block, which is placed in the groove and acts on the elastic arm; wherein the passive portion is restricted to move in the groove and is acted upon by the elastic arm so that the sliding block moves radially outward along the hollow tube body.

[0016] Furthermore, the elastic arm includes a first arm and a second arm which are connected as a whole and arranged in a stepped manner, and the second arm is formed at the bottom of the groove; the free end of the first arm acts on the passive part, and the height of the free end of the first arm is lower than the plane of the accommodating part.

[0018] Furthermore, blocking parts extend from both side walls of the locking part respectively, and a limiting space for partial insertion of the sliding block is formed between the blocking part and the accommodating part, so that the sliding block is limited from axial displacement along the hollow tube body by the blocking part.

[0019] Furthermore, two side portions of the sliding block also form a yielding portion, which is used for the blocking portion to pass through, and the inner side wall of the blocking portion and the yielding portion of the sliding block form a guiding fit.

[0037] See also Figure 1-2 and Figure 6 The present embodiment describes a component for quickly disassembling a faucet, which is used to fix the faucet to a countertop, that is, the faucet body 1 is connected to a screw tube 11, and after the screw tube 11 passes through the countertop 2, the quick disassembly component is sleeved on the outer wall of the screw tube 11, and the hollow tube body 3 and the limiting sleeve 4 are pushed axially, and the limiting sleeve 4 pushes the sliding block 5 to move radially, and the screw tube 11 is clamped (engaged) with the threaded portion (i.e., the screw teeth), and then the screw tube 11 is firmly installed by rotating it at a certain angle; when disassembling, the hollow tube body 3 is reversed, and the limiting sleeve 4 is no longer subjected to the force of the hollow tube body 3, and the sliding block 5 is reset by the elastic force of the elastic arm 6, and then the screw tube 11 is loosened, so that it can be easily disassembled;

[0038] The assembly of the faucet that can be quickly disassembled and assembled in this embodiment mainly includes the following parts: a hollow tube body 3, a limit sleeve 4, a sliding block 5, an elastic arm 6 and an elastic member 7;

[0039] like Figure 1 , 3As shown, the hollow tube body 3 is formed by injection molding and is a grippable stud; a receiving portion 31, a locking portion 32 and an escape channel 33 for radial displacement of the sliding block 5 are also formed at the end of the hollow tube body 3; the locking portion 32 and the receiving portion 31 are arranged in a stepped manner, and a screw thread 322 is formed on the inner wall surface of the locking portion 32, and the screw thread 322 is used to cooperate with the outer wall of the screw tube 11; and the hollow tube body 3 has a central hole 34, which is arranged to penetrate along the axial direction for the water inlet pipe 8 to pass through (that is, for the cold and hot water inlet pipes, the pull-out pipe, etc. to pass through), and an escape channel 33 is formed on the hole wall of the central hole 34. 3, that is, the avoidance channel 33 is formed on the inner wall surface of the hollow tube body 3 along the axial direction, and is also used for the water inlet pipe 8 to be placed or placed when passing through; this embodiment is illustrated by taking the avoidance channel 33 with a semicircular cross-sectional shape as an example, and the radius of the avoidance channel 33 is larger than the radius of the water inlet pipe 8, so that when the water inlet pipe 8 abuts against the avoidance channel 33, half or more of the water inlet pipe 8 is located in the avoidance channel 33 from the cross-sectional view, and the other half is located in the center hole 34, so that multiple water inlet pipes 8 can be smoothly inserted; in this way, the cold and hot water inlet pipes 8 can be directly installed on the faucet before leaving the factory, without the need for users to install them later, thereby reducing the difficulty of installation.

[0040] The accommodating portion 31 allows the sliding block 5 to slide in a radial straight line, and a guiding protrusion 91 is formed on the axial surface of the accommodating portion 31; in addition, a groove 311 is provided in the middle position of the accommodating portion 31, and the groove 311 is formed along the axial direction of the tube wall of the hollow tube body 3, and an elastic arm 6 protrudes from the groove bottom of the groove 311; in addition, the elastic arm 6 of the present embodiment is extended along the axial direction of the hollow tube body 3 toward the accommodating portion 31, and cooperates with the sliding block 5 in the radial direction to drive the sliding block 5 to reset; it should be noted that the elastic arm 6 includes a first arm 61 and a second arm 62 that are connected as a whole and arranged in a step-like manner, and the second arm 62 is formed at the groove bottom of the groove 311; the free end of the first arm 61 acts on the passive portion 51, and the height of the free end of the first arm 61 is lower than the plane of the accommodating portion 31, so that the passive portion 51 is partially inserted into the groove 311, and is guided by the side groove wall of the groove 311, the force and direction when the passive portion 51 presses against the elastic arm 6 are better, and the movement is more stable;

[0041] Blocking portions 321 extend from both side walls of the locking portion 32, and a limiting space A for partial insertion of the sliding block 5 is formed between the blocking portion 321 and the accommodating portion 31, so that the axial displacement of the sliding block 5 along the hollow tube body 3 is limited by the blocking portion 321. In this way, the translation of the entire sliding block 5 is more stable, and axial warping and the like are not likely to occur during the movement. When clamping, the corresponding fit between the screw thread and the screw tube 11 is more precise.

[0042] like Figure 1 , 2As shown, the sliding block 5 moves radially along the accommodating portion 31 and cooperates with the screw thread 322 on the locking portion 32 to clamp the faucet; it should be noted that the sliding block 5 is also formed with a screw thread 50 in the direction relative to the locking portion 32; in addition, the sliding block 5 has an inclined surface 52, where the inclined surface 52 is arranged opposite to the screw thread 50 and is inclined downward from the upper end surface toward the outer peripheral surface;

[0043] A passive portion 51 extends downward from the bottom of the sliding block 5 and is located in the middle position, and an adapting groove 92 is provided; the passive portion 51 is placed in the groove 311 and acts on the elastic arm 6; wherein the passive portion 51 is restricted to move in the groove 311 and is acted upon by the elastic arm 6, so that the sliding block 5 is displaced radially outwardly along the hollow tube body 3; it should be noted that the adapting groove 92 and the guide protrusion 91 of the accommodating portion 31 form a guide sliding structure.

[0044] In addition, the sliding block 5 has two sides formed with a yielding portion 54 and two ends extending toward the locking portion 32.

[0045] The stopper 321 is provided with the yielding portion 54 , and the inner wall of the stopper 321 forms a guiding match with the yielding portion 54 of the sliding block 5 ; and the plug-in portion 55 is correspondingly inserted into the limiting space A.

[0046] The limiting sleeve 4 is covered at the end of the hollow tube body 3, and when the limiting sleeve 4 moves axially in the direction of the hollow tube body 3, it pushes the sliding block 5 to move toward the locking portion 32 through the inclined surface; the limiting sleeve 4 is provided as a cover body, and has a through hole 41 corresponding to the central hole 34 and a clearance hole 45 corresponding to the avoidance channel 33 in the middle, and the through hole 41 and the clearance hole 45 are both used for the water inlet pipe 8 to pass through; in addition, a pressing portion 42 is formed inside the limiting sleeve 4, and the pressing portion 42 also has an inclined surface 42, which matches the inclined surface 52 of the sliding block 5;

[0047] The limiting sleeve 4 is covered on the end of the hollow tube body 3, and at least one guide rib 43 is formed on the inner wall and a hook portion 44 is formed along the outer periphery; a guide groove 36 is arranged axially on the outer periphery of the hollow tube body 3; wherein, the guide rib 43 of the limiting sleeve 4 is installed corresponding to the guide groove 36, so that the limiting sleeve 4 can move axially along the hollow tube body 3, and an axial activity space B is formed between the two; through the cooperation between the guide rib 43 and the guide groove 36, the limiting sleeve 4 can be smoothly and steadily displaced axially relative to the hollow tube body 3; this embodiment is illustrated by taking three guide grooves 36 as an example, and each guide groove 36 is formed at intervals on the outer periphery of the hollow tube body 3; here, the axial activity space B refers to the distance between the limiting sleeve 4 and the end face of the hollow tube body 3, so that the pressing portion 42 of the limiting sleeve 4 and the inclined surface 52 of the sliding block 5 no longer press against each other, and the sliding block 5 can be reset and translated to release the clamping.

[0048] In addition, the present embodiment is illustrated by taking two hooking portions 44 as an example, and the hooking portions 44 are hooked with the hollow tube body 3 to limit the limiting sleeve 4 from being separated from the hollow tube body 3, and the entire limiting sleeve 4 is sleeved on the hollow tube body 31 to prevent the sliding block 5 from being separated from the accommodation portion 31 in the axial direction and the radial direction;

[0049] In order to achieve faster reset of the limiting sleeve 4 in the loose state, an elastic member 7 (i.e., a spring) is further installed at the end of the hollow tube body 3, and the two ends of the elastic member 7 act on the hollow tube body 3 and the limiting sleeve 4 respectively, so as to drive the limiting sleeve 4 to move axially in the direction away from the hollow tube body 3 when the external force is lost.

[0050] Actual assembly process: Figure 1-6 As shown,

[0051] (1) The sliding block 5 is placed on the receiving portion 31, and the adapting groove 92 on the lower surface of the sliding block 5 corresponds to the guide protrusion 91 on the receiving portion 31, so that the sliding block 5 can move along the radial direction of the hollow tube 3;

[0052] (2) At this time, the passive portion 51 on the bottom of the sliding block 5 is located outside the elastic arm 6 of the groove 311, and the blocking portions 321 extending on both sides of the locking portion 32 correspond to the yielding portions 54 of the sliding block 5. At the same time, the plug-in portion 55 of the sliding block 5 is just inserted into the limiting space A. At this time, the sliding block 5 is restricted by the blocking portion 321 and cannot move along the axial direction of the hollow tube 3, but can only move in the radial direction; and the sliding block 5 is blocked by the elastic arm 6, and the screw thread on it does not extend into the central hole 34;

[0053] (3) The elastic member 7 (i.e., spring) is placed on the end surface of the hollow tube body 3, and the limiting sleeve 4 is correspondingly covered on the end of the hollow tube body 3; in this process, the pressing portion 42 of the limiting sleeve 4 corresponds to the inclined surface 52 on the sliding block 5; it should be noted that the pressing portion 42 is also an inclined surface, and the two form an inclined surface match; the guide rib 43 on the limiting sleeve 4 is installed corresponding to the guide groove 36 on the outer periphery of the hollow tube body 31, so that the limiting sleeve 4 can only move axially and cannot rotate circumferentially; in addition, the hook portion 44 is buckled on the hollow tube body 3 (or the hollow tube body 3 and the sliding block 5), so that the limiting sleeve 4 can move axially but will not separate from the hollow tube body 3;

[0054] (4) After the assembly is completed, the faucet body 1 equipped with the water inlet pipe 8 is packaged and sold together.

[0055] When actually using the installation:

[0056] (1) Before leaving the factory, the cold and hot water inlet pipes 8, the pull-out pipe, etc. can be first passed through the screw pipe 11 and then screwed with the valve core seat inside the faucet body 1, so that the cold and hot water inlet pipes 8, the pull-out pipe, etc. are first connected to the faucet body 1.

[0057] (2) Insert the cold and hot water inlet pipes 8, the drawer pipe, etc. through the openings on the table top 2 and extend them into the lower surface of the table top 2;

[0058] (3) The quick disassembly assembly is sleeved on the outer periphery of the cold and hot water inlet pipes 8 and the pull-out pipe; in this process, the cold and hot water inlet pipes 8 have threaded joints respectively, and one of the water inlet pipes 8 (such as the cold water inlet pipe 8) is first passed through the center hole 34, and then the water inlet pipe 8 is accommodated or docked at the corresponding avoidance channel 33, and then the other water inlet pipe 8 (such as the hot water inlet pipe 8) is passed through. When passing through, it is only necessary to slightly tilt the threaded joint so that there is enough space to directly pass through the center hole 34; then the pull-out pipe is inserted, and the cold and hot water inlet pipes 8 and the pull-out pipe can be passed through the quick disassembly assembly from the front;

[0059] (4) The assembly is directly sleeved upward from the free end of the screw tube 11 until the limiting sleeve 4 presses against the lower surface of the table 2 or the gasket installed on the lower surface of the table 2; the hollow tube 3 is held and pushed upward, the elastic member 7 is compressed, and the axial movable space B between the hollow tube 3 and the limiting sleeve 4 is compressed, so that the pressing portion 42 on the limiting sleeve 4 acts on the inclined surface 52 of the hollow tube 3, thereby driving the sliding block 5 to move toward the screw tube 11. At this time, the passive portion 51 of the sliding block 5 presses against the elastic arm 6, and the elastic arm 6 is bent and deformed inwardly, and the sliding block 5 is also linearly displaced by the action of the sliding structure until it and the screw thread 322 of the other half of the hollow tube 3 are engaged with the outer wall of the screw tube 11, and the screw thread is stuck to the screw tube 11;

[0060] (5) Rotate a certain angle so that the screw threads 322 and 50 match the outer wall threads of the screw tube 11, thereby achieving quick installation;

[0061] (6) When it is necessary to disassemble, the hollow tube body 3 is rotated in the opposite direction. Under the action of the elastic member 7, the hollow tube body 3 is quickly loosened relative to the limiting sleeve 4 but does not disengage, so that the pressing portion 42 of the limiting sleeve 4 no longer exerts force on the inclined surface 52; under the action of the elastic arm 6, the sliding block 5 quickly retreats to the original state, disengaging from the engagement with the threaded tube 11, so that the entire assembly can be quickly removed for easy maintenance and replacement; if it is a quick-install and quick-disassemble device in the prior art, it is necessary to remove the entire assembly and remove the hose on the faucet body 1, which makes disassembly difficult.

[0062] The utility model provides a component for quickly disassembling and assembling a faucet, which has a simple structure, is easy to manufacture, easy to implement and has low cost, and solves the problems that the elastic parts in the existing quick-disassembly and quick-assembly devices are easy to fail, the elastic restoring force is insufficient, and the space occupied is large; the utility model improves the quick-disassembly and assembly component used for fixing the faucet, which not only meets the requirements of quick disassembly and assembly, but also has fewer parts and a more ingenious structural design, and most importantly, can significantly reduce the size. Compared with the existing method of two sliding blocks and a plurality of radially or circumferentially arranged elastic components matched with the corresponding sliding blocks, the utility model only uses one sliding block and combines the design of an elastic arm protruding along the axial direction to set the outer diameter of the end of the hollow tube body to the minimum, and at the same time, the elastic force is better and the rebound effect is more significant; not only that, an avoidance channel is also provided in the hollow position of the hollow tube body, so that the water inlet pipe with a threaded joint can be installed through the front of the component during the assembly process, that is, the water inlet pipe with a threaded joint (such as a cold water inlet pipe) 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 center hole is reduced, and the pull-out pipe can be smoothly passed through and connected; on the basis of realizing rapid disassembly and assembly, the cold and hot water inlet pipes and the pull-out pipe can be assembled 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, the pull-out pipe, etc. can be directly sealed and assembled before leaving the factory, reducing the time for subsequent assembly by the staff or the user (assembly by professional tools before leaving the factory has better sealing performance), realizing rapid disassembly and assembly in a real sense, that is, the present invention can reduce the external dimensions while realizing the installation of at least two water inlet pipes with threaded joints from the front, and the installation and use occasions are wider and the practicality is better.

[0063] 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.
