DETAILED DESCRIPTION

[0020] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0021] Please refer to Figures 1-4 , a threaded steel connecting piece, comprising: a connecting stud 1, a connecting sleeve 2 and a self-locking assembly 3;

[0022] Please refer to Figure 2 , the connecting stud 1 is provided with a connecting sleeve 2 at both ends, the surface of the connecting stud 1 is provided with external threads 101 at both ends, the two external threads 101 are oppositely arranged, the inner wall of the connecting sleeve 2 is provided with internal threads 201, and the connecting stud 1 is threadedly connected with the internal threads 201 of the inner wall of the connecting sleeve 2 at both ends through the external threads 101 at both ends.

[0023] In specific use, the connecting stud 1 is provided with a connecting sleeve 2 at both ends, the surface of the connecting stud 1 is provided with opposite external threads 101 at both ends, the inner wall of the two connecting sleeves 2 is provided with internal threads 201, and when two threaded steels are connected, the two connecting sleeves 2 are sleeved on one end of the threaded steel, the connecting sleeve 2 is threadedly connected with the external threads 101 on the surface of the connecting stud 1 through the internal threads 201, and the two connecting sleeves 2 are reversely rotated, since the self-locking structure in the connecting sleeve 2 does not lock the threaded steel, the connecting sleeve 2 rotates relative to the threaded steel during the connecting process, so that only the connecting sleeve 2 needs to rotate relative to the connecting stud 1 during the connecting process, the threaded steel does not need to rotate together, and the operation and connection are facilitated.

[0024] Please refer to Figure 1 , Figure 3The self-locking component 3 includes a tapered sleeve 31 connected to one end of the connecting screw sleeve 2. One end of the tapered sleeve 31 has a feed hole 32. The tapered sleeve 31 has several locking pieces 33 inside, which are also tapered. The tapered sleeve 31 has a rubber ring 34 inside, and the locking pieces 33 are connected around the surface of the rubber ring 34. There is a certain gap between adjacent locking pieces 33. The connecting screw sleeve 2 has a washer 35 inside, and the bottom of the washer 35 contacts the surface of the rubber ring 34. The connecting screw sleeve 2 also has a spring 36 inside, and one end of the spring 36 contacts the surface of the washer 35. After the locking pieces 33 are tightened together, their inner diameter is larger than the diameter of the feed hole 32.

[0025] In practical use: The self-locking assembly 3 includes a tapered sleeve 31 connected to one end of the connecting sleeve 2. One end of the tapered sleeve 31 has a feed hole 32 to facilitate the threaded steel bar to pass through. The tapered sleeve 31 has several locking plates 33 inside, which are also tapered in shape. The locking plates 33 are mounted around the surface of the rubber ring 34, and there is a certain gap between adjacent locking plates 33, so that the locking plates 33 can contract relative to the rubber ring 34. The connecting sleeve 2 has a washer 35 and a spring 36 inside. When the threaded steel bar is inserted into the rubber ring 34, the locking plates 33 are attached to the outer wall of the threaded steel bar under the elastic tightening of the rubber ring 34. During the tightening process, the spring 36 is compressed and pushes the locking plate 33 on the surface of the rubber ring 34 into the conical sleeve 31 through the washer 35, so that the locking plates 33 come together and tighten the threaded steel. When the connecting stud 1 and the connecting sleeve 2 are tightened, the spring 36 pushes the locking plate 33 to lock the threaded steel. Since the inner diameter formed by the aggregation of the locking plate 33 is larger than the diameter of the material passage hole 32, the greater the tension between the threaded steel, the higher the tightness of the locking plate 33, ensuring the connection stability of the two threaded steels. In the traditional construction process of gas station roof steel structure, the connection between the threaded steels can be guaranteed to be stable, ensuring the structural stability.

[0026] Please see Figure 4 The surface of the rubber ring 34 is connected to the connecting sleeve 4, and one end of the locking piece 33 has an installation groove 5 that opens and closes, with the connecting sleeve 4 embedded inside the installation groove 5.

[0027] In practical use: the surface of the rubber ring 34 is connected to the connecting sleeve 4, which is embedded in the mounting groove 5 opened at one end of the locking piece 33, so that the locking piece 33 and the rubber ring 34 are tightly connected.

[0028] Please see Figure 4 The inner side of the locking piece 33 is provided with anti-slip texture 6.

[0029] In practical use: the inner side of the locking plate 33 is provided with anti-slip texture 6, which can increase the friction with the surface of the threaded steel and improve the locking ability.

[0030] Please see Figure 1 , Figure 3 A grouting hole 7 is provided through the surface of the connecting threaded sleeve 2.

[0031] In practical use: The surface of the connecting threaded sleeve 2 is provided with a grouting hole 7, which allows for the filling of cement grout and other filling materials as needed, and is suitable for different construction connection requirements.

[0032] Please see Figure 3 The gasket 35 is made of metal.

[0033] In practical use: the gasket 35 is made of metal so that it can push the locking piece 33 while replacing the rubber ring 34 to bear the force, thus preventing the locking piece 33 from falling off due to damage to the rubber ring 34.

[0034] Connecting sleeves 2 are provided at both ends of the connecting stud 1. The two ends of the surface of the connecting stud 1 are provided with opposite external threads 101. The inner walls of the two connecting sleeves 2 are provided with internal threads 201. When connecting two sections of threaded steel, the two connecting sleeves 2 are inserted and sleeved on one end of the threaded steel. The connecting sleeves 2 are threadedly connected to the external threads 101 on the surface of the connecting stud 1 through the internal threads 201. The two connecting sleeves 2 are held and rotated in opposite directions. Since the self-locking structure inside the connecting sleeves 2 does not lock the threaded steel, the connecting sleeves 2 rotate relative to the threaded steel during the connection process. This means that during the connection process, only the connecting sleeves 2 need to rotate relative to the connecting stud 1 to connect, without having to drive the threaded steel to rotate together, which is convenient for operation and connection.
