[0002] In the existing kitchen faucet, the installation nut is tightened from the rear end of the sleeve upwards, which takes a long installation stroke, a long time, and is not convenient to install. Other tools are required to complete the installation. Therefore, there is a nut for quick installation and removal in the prior art, which requires pushing the nut to the installation position, and then applying a thrust upward to make the nut tighten inwards to complete the locking work, which is laborious and unreliable. Summary of the invention

[0003] The main technical problem to be solved by the present invention is to provide a quick disassembly nut, which can shorten the installation stroke and installation time of the nut.

[0004] In order to solve the above technical problems, the present invention provides a quick disassembly nut, comprising: a body, at least two locking blocks;

[0005] The body has a through cavity along the axial direction for passing the sleeve under the table; the locking block is rotatably connected to the body, one end of which is placed in the through cavity to form a mounting end, and the other end is exposed outside the body to form an operating end; the mounting end has a thread connected to the sleeve;

[0006] When the operating end is operated, the mounting end swings between a first position and a second position; when the mounting end is in the first position, the mounting end is separated from the side wall of the sleeve; when the mounting end is in the first position, the mounting end is separated from the side wall of the sleeve; when the mounting end is in the second position, the thread of the mounting end abuts against the side wall of the sleeve.

[0007] In a preferred embodiment, it also includes an upper cover, which is movably mounted on one end of the through chamber facing the table top.

[0008] In a preferred embodiment, when the mounting end is swung from the first position to the second position, the mounting end abuts against the portion of the upper cover inserted into the through chamber, and pushes the upper cover to move toward the direction close to the table surface.

[0009] In a preferred embodiment: the side wall of the body is provided with a bayonet, and the upper cover has a buckle that movably cooperates with the bayonet.

[0010] In a preferred embodiment, the mounting end and the top abutment of the portion of the upper cover inserted into the through cavity are in a bevel fit.

[0011] In a preferred embodiment: the operating end is a button, and a return spring is connected between the operating end and the side wall of the body.

[0012] In a preferred embodiment: the locking block is rotatably connected to the body via a pin; the mounting end and the operating end are respectively located on both sides of the pin.

[0013] The present invention also provides a method for installing the quick disassembly nut as described above, comprising the following steps:

[0014] 1) Operate the operating end to swing the mounting end from the first position to the second position, and make it push the upper cover to move toward the table surface;

[0015] 2) Move the body upward along the axial direction of the sleeve until the upper cover abuts against the lower surface of the table;

[0016] 3) Release the operating end, swing the mounting end from the second position back to the first position, and rotate the body so that the locking block is engaged and fixed with the outer wall of the sleeve.

[0017] The present invention also provides a disassembly method of the quick disassembly nut as described above, comprising the following steps:

[0018] 1) Rotate the body to release the locking block from the outer wall of the sleeve;

[0019] 2) operating the operating end to swing the mounting end from the first position to the second position;

[0020] 3) Move the body downward along the axial direction of the sleeve until the body is separated from the sleeve;

[0021] 4) Release the operating end, swing the mounting end from the second position back to the first position, and the upper cover falls back to the initial position.

[0022] Compared with the prior art, the technical solution of the present invention has the following beneficial effects:

[0023] The present invention provides a quick disassembly nut. When installing the nut, the mounting end 21 is first swung to the second position through the operating end, and then the body is moved upward along the axial direction of the sleeve. Since the mounting end 21 is separated from the side wall of the sleeve 3, the body 1 has no obstacles in the upward movement and can move freely. When the nut is moved to a suitable position, the mounting end is swung to the first position through the operating end, so that the thread of the mounting end is in contact with the side wall of the sleeve, and then the body is rotated to allow the thread to engage and lock with the side wall of the sleeve 3. Therefore, the nut does not need to be screwed from the bottom of the sleeve, which greatly reduces the formation of screwing and is more labor-saving.

[0024] The present invention provides a quick disassembly and assembly nut, which is easy to operate. The installation end can be driven to swing by operating the operating end, so as to achieve abutment or separation with the sleeve. During installation, there is no need to consider the depth of the table top. As long as the nut passes through the sleeve to a position deemed appropriate by the installer, the installation end can be swung to the first position, and the nut can be rotated until it is tightened. There is no need to abut the table top before rotating the nut.

[0025] The present invention provides a quick disassembly and assembly nut with large locking force, which is not easy to loosen and has a double-layer clamping structure. When the installation end is in the first position, it is clamped inwardly on the sleeve by the action of a reset spring. When the nut is rotated to contact the top of the table, the upper cover receives the pressure of the table and moves downward. The limit surface thereof also has an inward squeezing force on the installation end, so that the installation end can clamp the sleeve with a larger locking force. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0032] refer to Figure 1-Figure 5 , a quick disassembly nut, movably matched with the sleeve under the table, comprising: a body 1, two locking blocks 2;

[0033] The body 1 has a through cavity along the axial direction for passing the sleeve 3 of the under-counter faucet; the locking block 2 is movably connected to the body 1, and a groove corresponding to the locking block is provided on the body. One end of the locking block is placed in the through cavity to form a mounting end 21, and the other end of the locking block is exposed outside the body 1 through the groove to form an operating end 22; the outer wall of the sleeve is provided with threads, and the mounting end 21 has threads connected to the sleeve 3; in this embodiment, the two locking blocks 2 are rotationally symmetrically distributed around the axial direction of the body 1. The outer side of the body corresponding to the operating end 22 is provided with a groove, and a convex rib 12 is provided in the groove;

[0034] The mounting end 21 is in an arc shape, two or three locking blocks can be provided, and the total arc angle range of the mounting end contacting the sleeve is between 180° and 360°. The operating end 22 is provided with a groove on one side facing the main body, and a convex rib 13 is provided in the groove;

[0035] When the operating end 22 is operated, the mounting end 21 swings between the first position and the second position; when the mounting end 21 is located at the first position, the mounting end 21 abuts against the side wall of the sleeve 3; when the mounting end 21 is located at the second position, the thread of the mounting end 21 is separated from the side wall of the sleeve 3.

[0036] Therefore, when installing the nut, the mounting end 21 is first swung to the second position through the operating end, and then the body 1 is moved upward along the axial direction of the sleeve 3. Since the mounting end 21 is separated from the side wall of the sleeve 3, the body 1 is free from any obstacles during the upward movement and can move freely. When the nut is moved to a suitable position, the mounting end 21 is swung to the first position through the operating end, so that the thread of the mounting end 21 is in contact with the thread of the side wall of the sleeve 3, and then the body 1 is rotated to make the thread and the thread of the side wall of the sleeve 3 match.

[0037] In this embodiment, the quick disassembly nut further includes an upper cover 4, which is movably mounted on one end of the through chamber facing the table. Specifically, the side wall of the body 1 is provided with a bayonet 11, and the upper cover 4 has a buckle 41 that movably cooperates with the bayonet 11; when the upper cover 4 moves toward the direction approaching the table, the buckle 41 moves upward along the axial direction relative to the bayonet 11, and the bayonet 11 limits the maximum displacement of the buckle 41 along the axial upward movement. When the upper cover 4 moves toward the direction away from the table, the buckle 41 moves downward along the axial direction relative to the bayonet 11, and the bayonet 11 limits the maximum displacement of the buckle 41 along the axial downward movement.

[0038] The mounting end 21 is provided with a limiting surface 23, and the portion of the upper cover 4 inserted into the through chamber is provided with another limiting surface 42. When the mounting end 21 swings from the first position to the second position, the limiting surface 23 and the limiting surface 42 abut against each other and push the upper cover 4 to move toward the table surface. In order to achieve the mounting end 21 pushing the upper cover 4 to move upward, in this embodiment, the limiting surface 23 and the limiting surface 42 are inclined surfaces.

[0039] In this embodiment, the operating end 22 is a button, and a reset elastic member is connected between it and the side wall of the main body 1. The reset elastic member is a reset spring 5. One end of the reset spring 5 is fixed on the convex rib 12, and the other end is fixed on the convex rib 13. The locking block 2 and the main body 1 are rotatably connected through a pin 6; the mounting end 21 and the operating end 22 are respectively located on both sides of the pin 6.

[0040] In this way, when the operating end 22 is pressed, the mounting end 21 will swing from the first position to the second position, and when the operating end 22 is released, the mounting end 21 will swing from the second position back to the first position.

[0041] The above-mentioned installation method of the quick disassembly nut comprises the following steps:

[0042] 1) Operate the operating end 22 to swing the mounting end 21 from the first position to the second position. During the swinging process, the limiting surface 23 cooperates with the limiting surface 42, so that the mounting end 21 pushes the upper cover 4 to move toward the table surface during the swinging process;

[0043] 2) Move the body 1 upward along the axial direction of the sleeve 3 until the upper cover 4 abuts against the lower surface of the table; at this time, since the upper cover 4 is limited by the limiting surfaces 23 and 42, the position of the upper cover 4 is fixed.

[0044] 3) Release the operating end 22, swing the mounting end 21 from the second position back to the first position, and rotate the body 1 so that the locking block 2 is engaged and fixed with the outer wall of the sleeve 3. Since the locking block 2 moves toward the direction close to the upper cover 4 during the rotation and fixing process, and the upper cover 4 is limited by the table top, the mounting end 21 is always close to the upper cover 4 during the rotation and fixing process of the locking block 2, so that the contact area between the limiting surface 23 and the limiting surface 42 is continuously increased. Since the upper cover 4 cannot move upward, the mounting end 21 of the upper cover 4 forms a radially inward limiting force during the process of the limiting surface 23 and the limiting surface 42 abutting against each other. Therefore, after the mounting end 21 is rotated and fixed in place, the operating end 22 becomes invalid and cannot drive the mounting end 21 to swing. In this way, the mounting end can be firmly fixed in the first position, and the quick disassembly nut can be prevented from falling off the sleeve 3.

[0045] This embodiment also provides a disassembly method of the quick disassembly nut as described above, comprising the following steps:

[0046] 1) Rotate the body 1 to release the locking block 2 from the outer wall of the sleeve 3; in this way, as the mounting end 21 moves away from the upper cover 4, the contact area between the limiting surface 23 and the limiting surface 42 gradually decreases, and the limiting cooperation with the upper cover 4 is gradually released. The operating end 22 becomes effective again.

[0047] 2) operating the operating end 22 to swing the mounting end 21 from the first position to the second position;

[0048] 3) Move the body 1 downward along the axial direction of the sleeve 3 until the body 1 is separated from the sleeve 3;

[0049] 4) Release the operating end 22, swing the mounting end 21 back from the second position to the first position, and the upper cover 4 falls back to the initial position.

[0050] The above is only a preferred embodiment of the present invention and cannot be used to limit the scope of the present invention. That is, equivalent changes and modifications made according to the patent scope of the present invention and the content of the specification should still fall within the scope of the present invention.
