[0023] In practical implementation: such as Figures 1-4 As shown, a quick-connect locking device for embedded parts and fasteners includes: a U-shaped screw 1, a pressure plate 2 on the upper surface of the U-shaped screw 1, a wooden block 4 at the bottom of the pressure plate 2, and a nut 3 threadedly connected to the upper surface of the U-shaped screw 1; a fastening mechanism 5, including a pressure plate 51 rotatably connected to the lower surface of the nut 3, a fixing frame 52 fixedly connected to the surface of the pressure plate 51, a sliding hole 53 on the inner wall of the fixing frame 52, rubber rods 55 slidably connected to both sides of the inner wall of the sliding hole 53, an inlet hole 56 on the inner wall of the rubber rods 55, a limiting groove 510 on the inner wall of the wooden block 4, a blocking block 57 engaged in the inner wall of the sliding hole 53, a through hole 58 on the inner wall of the blocking block 57, the upper surface of the wooden block 4 engaged in the inner wall of the pressure plate 2, the inner walls of the through hole 58 and the inlet hole 56 being recessed in a funnel shape, and the inner wall of the limiting groove 510 being recessed in a "T" shape. The surface of the rubber rod 55 is snapped onto the inner wall of the wooden block 4.
[0024] The U-shaped screw rod 1 is pre-buried in the corresponding installation site, such as the floor, by the existing pre-buried technology, the I-beam is hoisted to the U-shaped screw rod 1 by a special tool such as a crane, the bottom of the I-beam is abutted on the floor, two wooden blocks 4 are abutted at the corresponding positions inside the I-beam, the pressing plate 2 is sleeved on the U-shaped screw rod 1, the inner wall of the pressing plate 2 is clamped to the surface of the wooden block 4, the fixed frame 52 is clamped into the wooden block 4 due to the high height of the fixed frame 52, and then the nut 3 is accurately sleeved on the surface of the U-shaped screw rod 1 at the upper end, the nut 3 is threadedly installed on the U-shaped screw rod 1 by using an electric wrench, and then the bottom end of the nut 3 and the bottom end of the pressing disc 51 are abutted on the top of the pressing plate 2, and then the nut 3 is quickly butt-jointed and locked on the U-shaped screw rod 1, at this time the plug 57 is clamped into the sliding hole 53, the glue is injected into the through hole 58, the glue flows into the sliding hole 53 in the through hole 58, the glue in the sliding hole 53 flows into the two liquid inlet holes 56 respectively, the glue in the liquid inlet hole 56 flows into the inner wall recessed "T"-shaped limiting groove 510, after the glue solidifies, the rubber rod 55 is tightly clamped into the wooden block 4, and then the fixed frame 52 is tightly clamped into the wooden block 4, so that the nut 3 is locked, the pressing plate 2 and the wooden block 4 are tightly abutted on the I-beam, the I-beam is tightly installed on the floor, and subsequent installation operation can be performed.
[0025] As shown in Figure 3 , one end of the rubber rod 55 is fixedly connected with the spring 54, and the other end of the spring 54 is fixedly connected to the inner wall of the sliding hole 53.
[0026] As shown in Figure 3 , the surface of the rubber rod 55 is fixedly connected with the sliding block 59, and the surface of the sliding block 59 is slidingly connected to the inner wall of the sliding hole 53. Pulling the two sliding blocks 59 close to each other makes the rubber rod 55 retract into the sliding hole 53, and then the fixed frame 52 is quickly clamped into the wooden block 4, at this time the elastic force of the spring 54 pushes the rubber rod 55 to move and be clamped into the wooden block 4, and then the wooden block 4 is stably clamped in the pressing plate 2, and then the nut 3 is tightly threaded on the U-shaped screw rod 1.
[0027] As shown in Figure 2 , the bottom of the pressing plate 2 is fixedly connected with four abutting blocks 511, and the four abutting blocks 511 are distributed in a rectangular shape. Due to the high height of the abutting block 511, the abutting block 511 is abutted on the surface of the wooden block 4, and then the pressing plate 2 is accurately sleeved on the U-shaped screw rod 1.
[0028] In use, two wooden blocks 4 are placed against the corresponding positions on the inner side of the I-beam, and the abutment block 511 is placed against the surface of the wooden blocks 4. This allows the pressure plate 2 to be precisely fitted onto the U-shaped screw 1, and the inner wall of the pressure plate 2 to be precisely engaged with the surface of the wooden blocks 4. The fixing bracket 52 is engaged with the inside of the wooden blocks 4, allowing the nut 3 to be precisely fitted onto the upper surface of the U-shaped screw 1. The elastic force of the spring 54 pushes the rubber rod 55 to move and engage with the inside of the wooden blocks 4. An electric wrench is used to thread the nut 3 onto the U-shaped screw 1, so that the bottom end of the nut 3 is engaged with the pressure plate 51. The bottom end of the plate 2 abuts against the top of the pressure plate 2. At this time, the block 57 is inserted into the sliding hole 53, and glue is injected into the through hole 58. The glue flows from the through hole 58 into the sliding hole 53. The glue in the sliding hole 53 flows into the two liquid inlet holes 56 respectively. The glue in the liquid inlet holes 56 flows into the limiting groove 510. After the glue solidifies, the rubber rod 55 is fastened into the wooden block 4, and the fixing bracket 52 is fastened into the wooden block 4, thereby locking the nut 3. The pressure plate 2 and the wooden block 4 are tightly pressed against the I-beam, and the I-beam is fastened to the floor slab.
