[0024] Please see Figure 1-4 ,

[0025] Example 1: A quick-release T-bolt embedded part includes an anchor plate 1, a quick-release assembly 2 is provided on the anchor plate 1, a screw 3 is provided on the top of the quick-release assembly 2, a nut 4 is sleeved on the screw 3, and a flat washer 5 and a spring washer 6 are respectively provided on the bottom side of the nut 4. The flat washer 5 and the spring washer 6 are both sleeved on the screw 3.

[0026] The quick-release assembly 2 includes a fixed connecting block 201 set at the top of the anchor plate 1. The top of the fixed connecting block 201 is provided with a mounting screw groove 202. The bottom of the fixed connecting block 201 is vertically provided with a connecting stud 203. The middle of the anchor plate 1 is provided with a fixing insertion hole 204. The middle of the bottom end of the anchor plate 1 is provided with a bottom side mounting groove 205. The connecting stud 203 passes through the fixing insertion hole 204. The bottom end of the connecting stud 203 is fitted with a fixing nut 206.

[0027] Protrusions are provided on both sides of the top of anchor plate 1.

[0028] Example 2: The difference between this example and Example 1 is that the inner diameter of the mounting groove 202 is the same as the diameter of the screw 3.

[0029] This allows the bottom end of the screw 3 to be inserted into the mounting screw groove 202.

[0030] Example 3: The difference between this example and Example 1 is that the inner wall of the mounting groove 202 is provided with an internal thread that mates with the screw 3.

[0031] This allows for easy connection between the screw 3 and the mounting screw groove 202.

[0032] Example 4: The difference between this example and Example 1 is that the connecting stud 203 extends through the fixing hole 204 into the bottom mounting groove 205.

[0033] This allows the connecting stud 203 to be connected to the anchor plate 1 through the through fixing hole 204.

[0034] In this embodiment, since most existing T-bolt embedded parts are integrally formed by fixing, once the T-bolt embedded parts are installed, it is difficult to disassemble them due to subsequent project changes, equipment maintenance or replacement. Because they are tightly bonded to the concrete substrate, the disassembly process often requires damage to the concrete structure, which not only increases the disassembly cost and time, but also causes irreversible damage to the substrate, affecting the stability and service life of the structure.

[0035] In summary, during specific implementation, when the user needs to use this device for pre-embedded component installation, a quick-release assembly 2 is provided between the screw rod 3 and the anchor plate 1. The top of the fixed connecting block 201 in the quick-release assembly 2 has a mounting screw groove 202, which is threaded and can connect with the screw rod 3. Thus, the screw rod 3 can be fixed to the fixed connecting block 201 by the thread. A connecting stud 203 is vertically provided at the bottom of the fixed connecting block 201. The connecting stud 203 connects to the fixed connecting block 201 by... The through insertion of the fixed insertion hole 204, and the fixing nut 206 fitted on the bottom end of the connecting stud 203, can then fasten the fixing connecting block 201 and the anchor plate 1. The user can fix the anchor plate 1 in the pre-embedded position by pouring concrete. During the pouring process, the user needs to put a barrier sleeve on the screw rod 3 to prevent the concrete from contacting the surface of the screw rod 3, so that the anchor plate 1 can be fixed after the concrete has solidified. The user can then connect and install the workpiece to be installed through the screw rod 3.

[0036] When the user needs to disassemble the entire device, to facilitate the removal of the workpiece installed on the device, the user can rotate the screw 3 to unscrew it from the mounting screw groove 202. The anchor plate 1 and the quick-release connecting component 2 remain temporarily in the concrete, ensuring that the surface of the concrete substrate to be removed will not have a large protrusion due to the screw 3, which would affect the construction work. The screw 3 can be quickly removed. If not necessary, the anchor plate 1 and the quick-release connecting component 2 can remain in the concrete substrate. By sealing the disassembly holes with concrete, the substrate can be completely closed, preventing irreversible damage to the substrate, effectively ensuring the stability of its structure and improving its service life.
