[0023] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0024] Example 1:

[0025] A suspension steel bar tensioner, such as Figure 1 As shown, it includes a steel bar 4, a fixing plate 1, a tensioning rotary rod 2 and a locking member 3, wherein:

[0026] Fixing plate 1, such as Figure 2 As shown, it is fixed on the car at the position corresponding to the steel bar 4, and its overall shape is L-shaped, including a bottom plate and side plates, the bottom plate is fixed on the frame, and the side plates are provided with rotation holes 5;

[0027] Tensioning rod 2, such as Figure 3 As shown, a rod with different diameters is divided into two parts. The diameter of the first part 10 is smaller than the diameter of the rotating hole 5, and the diameter of the second part 11 is larger than the diameter of the rotating hole 5. When in use, the first part 10 can be passed through the rotating hole 5, so that the user can rotate the tensioning rotary rod 2. The first part 10 is provided with a thread near the second part 11, and the second part 11 is provided with a slot 6 on the side away from the first part 10. The slot 6 is perpendicular to the rotating axis of the tensioning rotary rod 2. When the user rotates the tensioning rotary rod 2, the steel bar 4 passing through the slot 6 will be wound onto the tensioning rotary rod 2, so that the tension of the steel bar 4 can be adjusted;

[0028] The locking member 3, in this embodiment, adopts a locking bolt, which can be threadedly matched with the thread of the first part 10 on the tensioning rotary rod 2. In this way, when the tensioning rotary rod 2 needs to be loosened, it is only necessary to slightly loosen the locking nut. When the tensioning rotary rod 2 needs to be locked, it is only necessary to tighten the locking nut. This is more convenient to use.

[0029] The working principle of this embodiment is: during normal installation, the fixing plate 1 is first installed on the frame, and then the tensioning rod 2 is passed through the rotating hole 5 of the fixing plate 1, and then the tensioning rod 2 is temporarily locked on the fixing plate 1 through the locking nut, and then the steel bar 4 is installed, and the steel bar 4 is passed through the slot 6 on the tensioning rod 2. If the tightness of the steel bar 4 needs to be adjusted at this time, the locking nut can be loosened with a wrench, and then the tensioning rod 2 is rotated. When the tightness of the steel bar 4 is appropriate after being rotated to a certain angle, the locking nut can be tightened with a wrench. At this time, the tensioning rod 2 is locked by the locking nut, and the tightness of the steel bar 4 will be maintained in this state, completing the adjustment of the tightness of the steel bar 4.

[0030] Example 2:

[0031] The difference from Example 1 is that in Example 1, the fixing plate 1 can be installed at any position of the steel bar 4 corresponding to the frame, while in Example 2, the fixing plate 1 needs to be installed on the top plate 7, and an adjustment hole 8 is also provided on the top plate 7, so that the user can extend the wrench from the adjustment hole 8 when using a wrench to loosen or tighten the locking nut, which is more convenient to use. After the fixing plate 1 is installed on the top plate 7, the tensioning rod 2 is extended out of the top plate 7 at one end for the user to operate, that is, the user can see the tensioning rod 2 from below, so the user can operate the tensioning rod 2 by simply extending his hand upwards, which is more convenient to operate.

[0032] Example 3:

[0033] The difference from the first embodiment is that in the third embodiment, a rotating portion 9 is provided at one end of the tensioning rod 2 for user operation. The rotating portion of this embodiment is four rotating surfaces, and the four rotating surfaces are respectively arranged in four directions, so that it is more convenient for the user to rotate the tensioning rod 2 with a wrench, and a spring 12 and a spring pad 13 are also provided on the tensioning rod 2 to play a certain buffering function.
