DETAILED DESCRIPTION

[0015] See Figure 1 、 Figure 2 The utility model includes an embedded mounting nut, a top plate 1, a main column 2, a threaded hole 20, a limiting ring 21, a limiting block 16, and a limiting plate 17. The top plate 1 is a rectangular plate body. The top plate 1 is composed of a fixed plate 11, an elastic rubber plate 12 and a movable plate 13 that are sequentially connected and arranged along the length direction of the top plate 1. A vertically arranged main column 2 is fixed to the bottom of the fixed plate 11. The main column 2 is cylindrical. A circle of limiting ring 21 is provided on the outer wall of the main column 2. The upward projection of the limiting ring 21 completely falls on the top plate 1. The threaded hole 20 is self-fixing. The top of the plate 11 extends vertically downward to the inside or bottom of the main column 2. A limit block 16 is fixed to the bottom of the movable plate 13. The limit block 16 includes two first limit sides parallel to the long side of the top plate 1. The first limit side is a vertical surface. The other sides of the limit block 16 are located in the area clamped by the planes where the two first limit sides are located. A limit plate 17 is fixed to the side of the limit block 16 close to the main column 2. The limit plate 17 is against the main column 2. The limit ring 21 and the limit plate 17 are both located in the area clamped by the planes where the two first limit sides are located.

[0016] Both sides of the elastic rubber plate 12 are provided with embedding strips 15, and the opposite sides of the fixed plate 11 and the movable plate 13 are provided with embedding grooves 14 adapted to the embedding strips 15. The embedding strips 15 are embedded in the embedding grooves 14, and the elastic rubber plate 12 and the fixed plate 11, and the elastic rubber plate 12 and the movable plate 13 are fixed by vulcanization bonding.

[0017] The limiting block 16 is in a rectangular parallelepiped shape, and the distance between the two first limiting side surfaces is smaller than the width of the top plate 1 .

[0018] The limiting plate 17 is provided with an arc-shaped contact surface 18 adapted to the outer wall of the main column 2 , and the arc-shaped contact surface 18 abuts against the main column 2 .

[0019] See Figure 3 、 Figure 4 The component on which the nut is installed includes a mounting plate 3, and a mounting hole is opened on the mounting plate 3. The mounting holes consist of a first mounting hole 31 and a second mounting hole 32. The first mounting hole 31 and the second mounting hole 32 both pass through the mounting plate 3. The second mounting hole 32 is a rectangular hole. The side wall where one of the short sides of the second mounting hole 32 is located is provided with a first mounting hole 31. The first mounting hole 31 is a semicircular hole adapted to the main column 2.

[0020] When the nut is installed, the main column 2 fits against the side wall of the first mounting hole 31, the top plate 1 and the limiting ring 21 clamp the mounting plate 3, the limiting plate 17 rests against the main column 2, and the three side walls of the limiting block 16 are respectively rested against the three side walls of the second mounting hole 32.

[0021] Working process of this utility model:

[0022] During the operation of the embedded mounting nut of the present invention, the main column 2 is first passed through the second through hole 32 until the first plate body 1 is fitted with the mounting plate 3. During this process, the elastic rubber plate 12 will bend upward, and the assembly consisting of the movable plate 13, the limit block 16, and the limit plate 17 will rise together. Then, the first plate body 1 is pressed and the nut is pushed toward the first through hole 31 until the main column is twice the side wall of the first through hole 31. At this time, the top plate 1 and the limit ring 21 clamp the mounting plate 3, and the limit block 16 will fall into the second through hole 32, completing the installation of the nut.
