Detailed Description

The invention is further described with reference to the drawings and the detailed description.

Referring to fig. 1-5, a quick-release nut, which is movably fitted to a lower sleeve of a table top, includes: the lock comprises a body 1 and two locking blocks 2;

the body 1 has a through chamber in the axial direction for passing through the sleeve 3 of the under-counter tap; the locking block 2 is movably connected with the body 1, a groove corresponding to the locking block is formed in the body, one end of the locking block is arranged in the through cavity to form an installation end 21, and the other end of the locking block is exposed outside the body 1 through the groove to form an operation end 22; the outer wall of the sleeve is provided with threads, and the mounting end 21 is provided with threads connected with the sleeve 3; in this embodiment, the two locking pieces 2 are rotationally symmetrically distributed around the axial direction of the body 1. The outer side of the main body corresponding to the operation end 22 is provided with a groove, and a convex rib 12 is arranged in the groove;

the mounting ends 21 are arc-shaped, two or three locking blocks can be arranged, the total arc surface angle range of the contact between the mounting ends and the sleeve is 180-360 degrees, one surface of the operating end 22, which faces the main body, is provided with a groove, and a convex rib 13 is arranged in the groove;

when the operating end 22 is operated, the mounting end 21 swings between a first position and a second position; when the mounting end 21 is in the first position, the mounting end 21 abuts against the side wall of the sleeve 3; when the mounting end 21 is in the second position, the threads of the mounting end 21 are disengaged from the side wall of the sleeve 3.

Therefore, when the nut is installed, the installation end 21 is firstly swung to the second position by the operation end, and then the body 1 is moved upward along the axial direction of the sleeve 3, and since the installation end 21 is separated from the side wall of the sleeve 3, the body 1 can move freely without any obstruction in the process of moving upward. And after the nut moved to suitable position, rethread operating end swung installation end 21 to first position, and the screw thread of installation end 21 just supports with the lateral wall screw thread of sleeve 3 like this, and then rotates body 1 and just can let screw thread and the lateral wall screw thread cooperation of sleeve 3.

In this embodiment, the quick-release nut further comprises an upper cover 4 movably attached to one end of the through cavity facing the table top. Specifically, a bayonet 11 is arranged on the side wall of the body 1, and the upper cover 4 is provided with a buckle 41 which is movably matched with the bayonet 11; when the upper cover 4 moves towards the direction close to the table top, the buckle 41 moves upwards along the axial direction relative to the bayonet 11, and the bayonet 11 limits the maximum displacement of the buckle 41 moving upwards along the axial direction. When the upper cover 4 moves in a direction away from the table top, the catch 41 moves downward in the axial direction relative to the catch 11, and the catch 11 limits the maximum displacement of the catch 41 moving downward in the axial direction.

Be equipped with a spacing face on the installation end 21 and be 23, the part that upper cover 4 inserted in running through the cavity is equipped with another spacing face 42, installation end 21 swings to the in-process of second position by first position, spacing face 23 with spacing face 42 takes place to push up to promote upper cover 4 and remove towards the direction that is close to the mesa. In order to realize that the mounting end 21 pushes the upper cover 4 to move upward, in this embodiment, the limiting surface 23 and the limiting surface 42 are inclined surfaces.

In this embodiment, the operation end 22 is a key, a return elastic element is connected between the operation end and the side wall of the body 1, the return elastic element is a return spring 5, one end of the return spring 5 is fixed on the convex rib 12, the other end of the return spring is fixed on the convex rib 13, and the lock block 2 is rotatably connected with the body 1 through a pin 6; the mounting end 21 and the operating end 22 are located on either side of the pin 6.

Thus, when the operation end 22 is pressed, the mounting end 21 swings from the first position to the second position, and when the operation end 22 is released, the mounting end 21 swings from the second position back to the first position.

The mounting method of the quick dismounting nut comprises the following steps:

1) operating the operating end 22 to swing the mounting end 21 from the first position to the second position, wherein the limiting surface 23 is matched with the limiting surface 42 in the swinging process, so that the mounting end 21 pushes the upper cover 4 to move towards the direction close to the table top in the swinging process;

2) moving the body 1 upwards along the axial direction of the sleeve 3 until the upper cover 4 is abutted against the lower surface of the table top; 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.

3) The operating end 22 is released, the mounting end 21 is swung from the second position back to the first position, and the body 1 is rotated so that the locking piece 2 is engaged with and fixed to the outer wall of the sleeve 3. Because the locking piece 2 moves towards the direction close to the upper cover 4 in the process of rotating and fixing, and the upper cover 4 is limited by the table top, in the process of rotating and fixing the locking piece 2, the mounting end 21 is always close to the upper cover 4, so that the contact area of the limiting surface 23 and the limiting surface 42 is continuously increased, and because the upper cover 4 cannot move upwards, in the process of propping the limiting surface 23 and the limiting surface 42, the mounting end 21 of the upper cover 4 forms a limiting force along the radial direction inwards, after the mounting end 21 is rotationally fixed in place, the operating end 22 fails and cannot drive the mounting end 21 to swing. Therefore, the mounting end can be firmly fixed at the first position, and the quick-assembly and disassembly nut can be prevented from falling off from the sleeve 3.

The embodiment also provides a method for disassembling the quick-disassembling nut, which comprises the following steps:

1) rotating the body 1 to enable the locking block 2 and the outer wall of the sleeve 3 to be disengaged and fixed; in the process that the mounting end 21 is far away from the upper cover 4, the contact area of the limiting surface 23 and the limiting surface 42 is gradually reduced, and the limiting fit with the upper cover 4 is gradually released. The operator end 22 is again active.

2) Operating the operating end 22 to swing the mounting end 21 from the first position to the second position;

3) moving the body 1 downwards along the axial direction of the sleeve 3 until the body 1 is separated from the sleeve 3;

4) the operating end 22 is released, the mounting end 21 is swung from the second position back to the first position, and the upper cover 4 is dropped back to the initial position.

The above description is only an exemplary embodiment of the present invention, and the scope of the present invention should not be limited accordingly. The equivalent changes and modifications made according to the patent scope and the content of the specification of the present invention should still fall within the scope covered by the present invention.
