[0016] The technical scheme in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative work belong to the protection scope of the utility model.

[0017] Embodiment 1: please refer to Figures 1-4 The utility model provides a technical scheme: integral type self-locking reinforcing bar connector, including the self-locking sleeve 1 of two ends opening, the self-locking sleeve 1 is made of carbon steel, and the carbon steel includes KS standard's S45C, SCM440, SCM450, preferably selects small steel, but is not limited to this;

[0018] The reinforcing bar body 2 is inserted into the both ends of the self-locking sleeve 1, and the both ends of the self-locking sleeve 1 are conical bodies 3, the limiting spring 4 is arranged in the self-locking sleeve 1, and the inner diameter of the limiting spring 4 is formed to be relatively larger than the diameter of the reinforcing bar body 2 to be connected.

[0019] The locking piece 5 is attached in the conical body 3 of the both ends of the self-locking sleeve 1, and the both ends of the limiting spring 4 are connected with the locking piece 5 respectively.

[0020] Example 2: As Figure 2 As shown, the locking component 5 consists of multiple locking plates 501, which are combined into a conical structure. The outer surface of the locking plates 501 is tightly fitted to the inner wall of the conical body 3. A continuous annular groove 6 is formed in the multiple locking plates 501, and a support ring 502 is provided in the annular groove 6. The support ring 502 is used to make the outer surface of the locking plates 501 fit tightly against the inner circumferential surface of the conical body 3. It should be noted that when the reinforcing bar body 2 passes through the internal through hole formed by the multiple locking plates 501, the design of the support ring 502 enables the multiple locking plates 501 to move synchronously. The inner diameter of the opening at the end of the self-locking sleeve 1 is larger than the diameter of the reinforcing bar body 2. When the reinforcing bar body 2 is inserted into the self-locking sleeve 1, the limiting spring 4 can elastically bias the locking plates 501 into the conical bodies 3 at both ends of the self-locking sleeve 1.

[0021] Example 3: As Figure 2 As shown, multiple locking plates 501 are provided with protrusions 503 at equal intervals. It should be noted that the through holes formed by the inner surfaces of the multiple locking plates 501 have the same inner diameter at both ends, that is, the cross-section of the through holes is rectangular. The protrusions 503 are serrated and inclined towards the center of the self-locking sleeve 1. That is, when the reinforcing bar body 2 is inserted into the through hole formed by the locking plates 501 through the opening of the self-locking sleeve 1, the transverse ribs on the reinforcing bar body 2 rub against the protrusions 503, but it can still be directly inserted into the self-locking sleeve 1. When the reinforcing bar body 2 is pulled out, the transverse ribs on the reinforcing bar body 2 will engage with the protrusions 503, thereby preventing the reinforcing bar body 2 from being pulled out, thus achieving the self-locking effect of the reinforcing bar body 2.

[0022] Example 4: Figure 2 and Figure 3 As shown, a limiting hole 7 is provided at the center of the self-locking sleeve 1, and observation holes 8 are provided on both sides of the limiting hole 7. A limiting rod 9 is inserted into the limiting hole 7. It should be noted that the design of the observation hole 8 can confirm the insertion state of the reinforcing bar body 2 connected to the self-locking sleeve 1. The observation hole 8 can be formed in the form of a circle, an ellipse or a long hole so as to confirm the connection part of the reinforcing bar body 2.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
