[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0017] Example: Please refer to Figure 1 - Figure 6 The screw with a T-shaped nut shown includes a T-shaped nut body 1, a tightening component 2 and a bolt body 3. The end face of the T-shaped nut body 1 is symmetrically provided with a mounting groove 8. A sealing component 4 is installed in the mounting groove 8. Through grooves 6 are provided on the front and rear sides of the inner cavity of the mounting groove 8. A cleaning component 7 is installed in the through groove 6. The closure 4 includes a spring 402, the spring 402 is installed on the bottom surface of the inner cavity of the mounting groove 8, and the closure plate 401 is installed on the end face of the spring 402; When the T-nut body 1 is not in use, the sealing plate 401 seals the mounting groove 8 to prevent the mounting groove 8 from being blocked by mud and sand, and to facilitate the adjustment of the T-nut body 1 during subsequent maintenance.

[0018] In this embodiment, specific references Figure 1 - Figure 4 Limiting blocks 5 are symmetrically installed on the upper inner side of the mounting groove 8, and the closing plate 401 is engaged with the two limiting blocks 5. The limiting block 5 is used to limit the rising height of the sealing plate 401 to prevent the sealing plate 401 from rising outside the mounting groove 8.

[0019] In this embodiment, specific references Figure 1 - Figure 4 The end faces of the two limiting blocks 5 are on the same horizontal plane as the top surface of the closing plate 401; The fact that they are on the same plane makes it easy to wipe away and clean the mud and sand on the end faces of the limiting block 5 and the closing plate 401.

[0020] In this embodiment, specific references Figure 1 - Figure 4 The cleaning component 7 includes a first mounting frame 701, a second mounting frame 702 installed on the side of the inner cavity of the through groove 6 near the mounting groove 8, and a first mounting frame 701 installed on the side of the inner cavity of the through groove 6 away from the second mounting frame 702. A connecting post 705 is slidably arranged between the first mounting frame 701 and the second mounting frame 702. A limit frame 704 is installed on the outer wall of the connecting post 705, and the limit frame 704 is located between the first mounting frame 701 and the second mounting frame 702. The end face of the connecting post 705 located inside the mounting groove 8 is arc-shaped. A pushing block 703 is installed on the end of the connecting post 705 away from the mounting groove 8. The outer wall of the pushing block 703 is in contact with the inner wall of the through groove 6. When the through groove 6 is needed for maintenance, an iron rod can be inserted into the through groove 6 and the T-nut body 1 can be turned. When the through groove 6 is blocked by mud and sand, the plug-in bracket 201 or other objects can be used to press the closing plate 401. When the closing plate 401 moves downward, the closing plate 401 squeezes the arc surface of the connecting column 705, thereby pushing the connecting column 705, the pushing block 703 and the limiting frame 704 outward, thereby discharging the mud and sand in the through groove 6 and achieving the effect of quickly cleaning the mud and sand in the through groove 6.

[0021] In this embodiment, specific references Figure 1 and Figure 6 The screwing assembly 2 includes a plug bracket 201, and a handle 202 is installed on the end face of the plug bracket 201.

The bottom end of the plug-in bracket 201 presses the sealing plate 401, and the sealing plate 401 squeezes the spring 402 and moves down. After the plug-in bracket 201 is inserted into the mounting groove 8, the handle 202 is turned to drive the plug-in bracket 201 and the T-nut body 1 to rotate. After rotating to the appropriate position, the plug-in bracket 201 is pulled out from the mounting slot 8. Then, under the action of the spring 402, the sealing plate 401 is reset upward, and the sealing plate 401 will be engaged with the limit block 5, thereby preventing wind and sand from entering the mounting slot 8, making maintenance more convenient and improving maintenance efficiency. When the through groove 6 is needed for maintenance, an iron rod can be inserted into the through groove 6 and the T-nut body 1 can be turned. When the through groove 6 is blocked by mud and sand, the plug-in bracket 201 or other objects can be used to press the closing plate 401. When the closing plate 401 moves downward, the closing plate 401 squeezes the arc surface of the connecting column 705, thereby pushing the connecting column 705, the pushing block 703 and the limiting frame 704 outward, thereby pushing out the mud and sand in the through groove 6. After the mud and sand are pushed out, the iron rod can be inserted into the through groove 6 to adjust the T-nut body 1.
