DETAILED DESCRIPTION OF THE EMBODIMENTS
[0022] The present utility model will be further described below in conjunction with specific embodiments:
[0023] As Figures 1-3As shown: A double-headed connecting piece structure includes a rod body 1. Elastic left and right connecting sleeves 2 and 3 are respectively screwed on the left and right ends of the rod body 1. The left and right connecting sleeves 2 and 3 have opposite screwing directions on the rod body 1. When the left and right connecting sleeves 2 and 3 approach each other, the diameters of the left and right connecting sleeves 2 and 3 gradually increase. When the left and right connecting sleeves 2 and 3 move away from each other, the diameters of the left and right connecting sleeves 2 and 3 gradually decrease. Specifically, for the rod body of the present utility model, it only needs to be inserted into two hollow rods without processed threads. The two hollow rods are rotated. The left and right connecting sleeves on the rod body contact the inner walls of the hollow rods. The two hollow rods are continuously rotated. When the left and right connecting sleeves approach each other and the left and right connecting sleeves abut against the inner sides of the hollow rods, the connection can be completed in this way. The rod body can reinforce the connection ends of the two hollow rods, the connection is convenient, and there is no need to process threads on the hollow rods anymore, reducing the processing steps and the scrap rate of the hollow rods at the same time.
[0024] In the above double-headed connecting piece structure, the rod body 1 includes a strengthening section 11, a left threaded section 12 and a right threaded section 13. The strengthening section 11 is located between the left threaded section 12 and the right threaded section 13. The left connecting sleeve 2 is screwed on the left threaded section 12, and the right connecting sleeve 3 is screwed on the right threaded section 13. The threads on the left threaded section 12 and the right threaded section 13 are tapered threads, and their large ends face the strengthening section 11. Specifically, in this way, when the left and right connecting sleeves rotate and approach each other, their diameters will gradually increase; when they move away from each other, their diameters will gradually decrease.
[0025] In the above double-headed connecting piece structure, at least two groups of reinforcing ribs 14 are arranged on the strengthening section 11. Specifically, this is to increase the strength and toughness of the rod body.
[0026] In the above double-headed connecting piece structure, limiting discs 4 for restricting the left and right connecting sleeves 2 and 3 from detaching from the rod body 1 are arranged at both ends of the rod body 1. Specifically, this is to prevent the left and right connecting sleeves from detaching from the rod body.
[0027] In the above double-headed connecting piece structure, notches 5 are arranged on the left and right connecting sleeves 2 and 3. Specifically, this can facilitate the left and right connecting sleeves on the rod body.
[0028] In the above double-headed connecting piece structure, anti-slip strips 6 are arranged on the outer sides of the left and right connecting sleeves 2 and 3. Specifically, there are eight or seven or six anti-slip strips, and the anti-slip strips are evenly distributed on the outer sides of the left and right connecting sleeves.
[0029] In the above double-headed connecting piece structure, a guiding chamfer 61 is provided at one end of the anti-slip strip 6 facing away from the rod body 1. Specifically, this is to facilitate the operator to insert the rod body into the hollow rod.
[0030] In the above double-headed connecting piece structure, a connecting sleeve limiting portion 15 is provided between the reinforcing section 11, the left threaded section 12 and the right threaded section 13. A limiting ring 16 is provided at the middle end of the reinforcing section 11. Specifically, the designed connecting sleeve limiting portion is to prevent the left connecting sleeve from disengaging from the left threaded section and prevent the right connecting section from disengaging from the right connecting section; at the same time, the designed limiting ring is to limit the hollow rod so that the hollow rod is accurately positioned. When the left connecting sleeve and the right connecting sleeve approach each other, the outer diameter thereof is larger than the diameter of the connecting sleeve limiting portion. In this embodiment, the connecting sleeve limiting portion is of an annular structure.
[0031] In the above double-headed connecting piece structure, elastic ribs 17 are further provided on the reinforcing section 11. Specifically, an avoidance groove is provided in the middle of the elastic ribs. When the hollow rod is sleeved on the reinforcing section, the outer side surface of the elastic ribs contacts the inner side of the hollow rod to prevent the hollow rod from disengaging from the rod body.
[0032] The above embodiments are only preferred embodiments of the present invention and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of the present invention shall be covered within the protection scope of the present invention.
