AI Technical Summary
Existing steel bar tensile strength testing devices cannot ensure the verticality of the steel bars when clamping them, leading to errors in the test results.
The design incorporates a limiting component, which is fixed to the clamp position via a limiting ring. This allows both ends of the rebar to pass through the limiting ring and enter the clamp, ensuring that the rebar remains vertical during inspection.
This improves the accuracy of tensile strength testing of steel bars and reduces errors in test results.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.
[0021] like Figures 1-3 As shown, a steel bar tensile strength testing instrument includes a testing instrument assembly comprising a base 11 and a testing instrument body 12 fixed above the base 11. The testing instrument body 12 includes two sets of clamps 13 arranged vertically opposite each other. A limiting assembly includes a set of first fixed shafts 23 arranged opposite each other on both sides of the clamps 13. The first fixed shafts 23 are fixed to the base 11, and each end of the first fixed shaft 23 is connected to a first connecting rod 24. The other ends of the two first connecting rods 24 are rotatably connected to a second fixed shaft 25. A fixing block 26 is fixed on the second fixed shaft 25, and a limiting ring 27 is connected between the two fixing blocks 26. The limiting ring 27 matches the diameter of the steel bar and is located on one side of the clamping end of the clamps 13 and is collinear with the center line of the clamps 13.
[0022] The clamp 13 is used to clamp and fix both ends of the reinforcing bar, and the base 11 is used to support the testing instrument body 12 and the clamp 13. The testing instrument body 12 is used to move the clamp 13 and measure the tensile strength data. The clamp 13 located above the testing instrument body 12 can slide up and down to accommodate different lengths of reinforcing bars.
[0023] The first fixed shaft 23 is slidably connected to the base 11 via a sliding assembly. The sliding assembly includes a slide groove 21 formed on the base 11. The slide groove 21 has two grooves, each matching two sliders 22. The two ends of the first fixed shaft 23 are respectively fixed to two sliders 22 located inside different slide grooves 21. The distance between the two sliders 22 located in the same slide groove 21 is adjusted by an adjustment assembly.
[0024] The slide 21 is used to support and guide the slider 22. The slider 22 is used to support the first fixed shaft 23. The first fixed shaft 23 is used to support the first connecting rod 24. The first connecting rod 24 is used to drive the second fixed shaft 25 to move. The second fixed shaft 25 is used to drive the fixed block 26 to move. The fixed block 26 is used to support the limiting ring 27. The limiting ring 27 is used to limit the rebar.
[0025] When both ends of the reinforcing bar are inside the limiting ring 27, the reinforcing bar can be kept vertical.
[0026] When the second fixed shaft 25 moves under the action of the first connecting rod 24, the fixed block 26 moves with the second fixed shaft 25.
[0027] Working principle: when the tensile strength test of the steel bar is needed, the two ends of the steel bar are respectively placed in the limiting ring 27, and the two ends of the steel bar are clamped by the control clamp 13. Since the center line of the limiting ring 27 and the center line of the clamp 13 are collinear, the steel bar in the limiting ring 27 and the clamp 13 can be kept in a vertical state. At this time, the test instrument body 12 is controlled to stretch the steel bar through the clamp 13, so that the tensile strength data of the steel bar can be accurately measured.
[0028] Please refer to Figure 4 The embodiment further comprises:
[0029] The adjusting assembly comprises a supporting block 31 fixed on the base 11, a horizontally arranged screw rod 32 is arranged on the supporting block 31, one end of the screw rod 32 is fixed with a disc 33, the disc 33 is arranged in the inner part of an activity plate 34 and is vertically rotatably connected with the activity plate 34, two second connecting rods 35 are rotatably connected with the two sides of the activity plate 34 respectively, and the other ends of the second connecting rods 35 are rotatably connected with the two sliding blocks 22 in the same sliding groove 21. The second connecting rod 35 is horizontally arranged, and the bottom end of the activity plate 34 is in contact with the base 11.
[0030] When the activity plate 34 moves, the activity plate 34 drives the second connecting rod 35 to rotate, and the second connecting rod 35 drives the sliding block 22 to slide in the sliding groove 21.
[0031] Working principle: when it is needed to conveniently take out the steel bar from the limiting ring 27, the screw rod 32 is rotated to drive the disc 33 to rotate, the screw rod 32 moves horizontally under the action of the threaded structure and drives the disc 33 to move horizontally, the disc 33 rotates in the activity plate 34 to drive the activity plate 34 to move, the bottom end of the activity plate 34 is in contact with the base 11 and the bottom end of the test instrument body 12, so that the activity plate 34 can only move horizontally, the activity plate 34 drives the second connecting rod 35 to rotate, and the second connecting rod 35 drives the sliding block 22 to slide along the sliding groove 21, the sliding block 22 drives the limiting ring 27 to move vertically through the first connecting rod 24, the limiting ring 27 moves to the clamp 13 to lengthen the distance between the limiting ring 27, so that the steel bar can be conveniently taken out. It meets the needs of the strength test of multiple steel bars with the same length, and the distance of the clamp 13 does not need to be frequently adjusted.
