[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model. The present utility model is not limited to the following embodiments.

[0026] As Figures 1 to 3 shown, this embodiment discloses a concealed quick-installation connecting piece integrated rod, which sequentially includes a rod head 1, a rod body 2, and a connecting seat 3 from top to bottom. A fastening sleeve 4 is sleeved on the rod body 2. The fastening sleeve 4 is fixedly connected to the rod body 2 by injection molding. One end of the rod body is fixedly connected to a mounting plate through the connecting seat 3, and the other end passes through a plate hole on another mounting plate through the rod head 1 and is clamped and matched with the plate hole through the fastening sleeve 4. In order to facilitate the fixation of the connecting seat 3, the connecting seat 3 is threadedly connected to the mounting plate. An external thread structure 31 for screwing and fitting on the mounting plate is provided on the connecting seat 3. The thread type of the external thread structure 31 can be adaptively designed according to the material or structural strength of the mounting plate to facilitate improving the connection strength between the connecting seat 3 and the mounting plate. It can be determined that the fastening sleeve 4 is in interference fit with the plate hole on the mounting plate. When one end of the rod head 1 is inserted into the plate hole, clamping fixation can be achieved through the fastening sleeve 4, and there is no need to use an eccentric wheel for fixation, making the installation more convenient and fast. Further, a limiting ring 32 is provided between the rod body 2 and the connecting seat 3. One end of the fastening sleeve 4 abuts against the limiting ring 32. Since the fastening sleeve 4 is formed by injection molding, there is a spacing between the other end of the fastening sleeve 4 and the rod head 1 to facilitate connection with the upper mold. In addition, the reserved spacing can also save the material cost of manufacturing the fastening sleeve 4.

[0027] In this embodiment, in order to improve the fixing effect between the fastening sleeve 4 and the plate hole, a plurality of groups of sequentially arranged reverse tooth structures 41 are provided on the outer side of the fastening sleeve 4. The reverse tooth structures 41 are arranged annularly around the fastening sleeve 4, and the tips of the reverse tooth structures 41 are biased towards the side of the connecting seat 3. After the rod body extends into the plate hole through the reverse tooth structures 41, the cooperation with the plate hole is closer, and the reverse tooth structures 41 can greatly increase the friction force between the fastening sleeve 4 and the plate hole, avoiding the loosening of the cooperation with the plate hole.

[0028] Furthermore, a plurality of groups of locking teeth 42 are also provided on the outer side of the fastening sleeve 4. The plurality of groups of locking teeth 42 are arranged annularly around the fastening sleeve 4. Preferably, the locking teeth 42 are arranged at the tooth gaps between two adjacent groups of the reverse tooth structures 41, and the locking teeth 42 extend outward from the tooth gaps to the tips of the teeth. After the rod body is inserted into the plate hole through the locking teeth 42, axial limitation can be formed, avoiding the situation that the fastening sleeve 4 rotates relative to the plate hole during use due to vibration, resulting in the loosening of the connection between the connecting seat 3 and the mounting plate; moreover, in order to improve the axial limitation effect, among the plurality of groups of locking teeth 42 arranged in the same annular arrangement, at least two opposite groups of the locking teeth 42 have ends extending beyond the tips of the teeth, and the parts of the locking teeth 42 extending beyond the tips of the teeth can effectively be stuck inside the plate hole.

[0029] Furthermore, at least two rows of locking teeth 42 are provided on the fastening sleeve 4. In this embodiment, the two rows of locking teeth 42 are respectively arranged at positions close to the two ends of the fastening sleeve 4. The two rows of locking teeth 42 are sufficient to improve the axial limitation effect, and at the same time can avoid the structure being too complex and increasing the production difficulty.

[0030] In this embodiment, a notch 10 for rotating the rod body is provided at the top of the rod head 1. The notch 10 can be a cross slot or a flat slot. Through the notch 10, it is convenient to select the connecting seat 3 on the rod body onto the mounting plate, improving the convenience.

[0031] In this embodiment, a raised structure 21 for increasing the friction force between the fastening sleeve 4 and the rod body 2 is provided on the rod body 2. The fastening sleeve 4 wraps the raised structure 21. The raised structure 21 is arranged at one end of the rod body 2 close to the connecting seat 3; the raised structure 21 is a spiral thread structure; or a grid pattern structure.
