However, although the existing nuts can be quickly assembled and disassembled, the push cover and the thread block only contact through the first slope and the second slope. If the push cover slightly retreats upward during installation, the thread block will It will move outward, and the clamping force will be lost between the screw block and the pipe joint, making the installation unreliable or even invalid

Embodiment Construction
[0047] Please check Figure 1 to Figure 5 , the first preferred embodiment of the quick-installation and quick-release nut structure, the quick-installation and quick-release nut structure, which is screwed and matched with the screw 1, includes a first body 10, a second body 20, and several screw teeth Block 30 and limiting part 40.
[0048] The first body 10 is provided with an activity chamber 11, and the inner wall of the activity chamber 11 is provided with a first slope 12.
[0049] In this example, if figure 2 with image 3 As shown, the first body 10 includes a first upper body 13 and a first lower body 14 connected to the first upper body 13, the movable chamber 11 is located between the first upper body 13 and the first lower body 14, and the first upper body 13 is connected to the first lower body 14. A slope 12 is disposed on the inner wall of the first upper body 13 . The first upper body 13 and the first lower body 14 are fixed by threaded connection, or the...

The invention discloses a quick mounting and dismounting nut structure. A threaded rod is sleeved with a nut; a second body moves upwards to drive thread blocks to move upwards when the nut pushes against upwards to a table top; a first oblique surface is matched with a second oblique surface to drive the thread blocks to move to a central axis till a normal thread diameter is defined by thread diameters of all the thread blocks; the second body is rotated to drive a first body and the thread blocks to rotate to allow the thread blocks to be in lock fit with the threaded rod; and a limiting component axially supports the thread blocks when the thread blocks are in lock fit with the threaded rod. Since the nut is provided with the limiting component in the first body; when the thread blocks are in lock fit with the threaded rod, the limiting component axially supports the thread blocks; loss of the enclasping force between the thread blocks and the threaded rod due to downward and outward movement of the thread blocks arising from loosening of the first body is avoided; the locking state between the thread blocks and the threaded rod can be ensured before unlocking of the thread blocks and the threaded rod; and the nut and the threaded rod are mounted more reliably.
Description
technical field [0001] The invention relates to a quick-install and quick-release nut structure. Background technique [0002] At present, the kitchen faucets on the market are mainly installed close to the wall. At the same time, due to the sinking shape of the kitchen stainless steel sink, there is very little space for locking the faucet under the countertop. Most faucets and basins are fixed by screw connections. According to the current locking operation between the nut and the screw, the nut must be rotated from the lower end of the screw. The effective length of the screw is determined by the different thickness of the table, which determines the length of the lock nut. The space under the installation table is quite narrow, and the operating room is limited. There is the time-consuming and labor-intensive problem of locking the nut. [0003] In view of this, quick-installation and quick-release nuts came into being. However, although the existing nuts can be quickl...
