Detailed Implementation

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Please see Figs. 1-3 A rebar strength testing device includes a base 1, H-shaped frames 2 fixedly installed at both ends of the upper surface of the base 1, rollers 3 movably connected inside the H-shaped frames 2, and rebar bodies 4 in contact with the outer walls of the rollers 3. Support plates 5 are fixedly connected at both ends of the upper surface of the base 1, and a top plate 10 is fixedly connected to the top of the support plates 5. A hydraulic cylinder 11 is fixedly installed at the center of the upper surface of the top plate 10. The bottom end of the output end of the hydraulic cylinder 11 penetrates through the bottom of the top plate 10, and a pressing structure 12 is provided at the bottom end of the output end of the hydraulic cylinder 11. A fixing structure 13 is provided on the upper surface of the base 1.

[0024] A placement hole 6 is provided at the center of the bottom end of the support plate 5, and a limiting hole 7 is provided at the center of the right side of the support plate 5. A connecting hole 8 is provided inside the support plate 5 near the placement hole 6, and rectangular holes 9 are provided on both sides of the right side of the support plate 5 near the limiting hole 7. The limiting hole 7 and the rectangular holes 9 are connected by the connecting hole 8. Through the cooperation of the pressing structure 12 and the fixing structure 13, the hydraulic cylinder 11 is activated. The hydraulic cylinder 11 drives the movable plate 121 to move downward through the output end, and the movement of the movable plate 121 drives several V-shaped extrusions. Block 124 performs strength tests on multiple parts of the steel bar body 4, which reduces the time wasted on repetitive operations and improves work efficiency. At the same time, by pulling the pull ring 2138 and pull ring 128, the limiting post 2137 and limiting post 127 are pulled out from the through hole 2136 and through hole 126, respectively. Then, the V-shaped extrusion block 2134 and V-shaped extrusion block 124 can be adjusted, so that the device can fix steel bars of different outer diameters and different parts for testing, thus improving the practicality of the device to a certain extent.

[0025] The pressing structure 12 includes a movable plate 121, a limiting groove 122, a limiting block 123, a V-shaped extrusion block 124, a tooth 125, a through hole 126, a limiting post 127, a pull ring 128, a king-shaped limiting plate 129, and a buffer spring 1210. The center of the upper surface of the movable plate 121 is fixedly connected to the bottom end of the output end of the hydraulic cylinder 11. Several limiting grooves 122 are opened on the front outer wall of the movable plate 121. Limiting blocks 123 are movably connected inside the limiting grooves 122. A V-shaped extrusion block 124 is fixedly connected to the bottom end of the limiting block 123. A tooth 125 is fixedly connected inside the V-shaped extrusion block 124. A through hole 126 is opened on the right side of the movable plate 121. The internal movable connection of 126 includes a limiting post 127. The right end of the limiting post 127 is fixedly connected to a pull ring 128. Both ends of the movable plate 121 are fixedly connected to king-shaped limiting plates 129. The bottom end of the king-shaped limiting plate 129 is fixedly connected to a buffer spring 1210. By adopting the above technical solution, when it is necessary to remove and adjust the spacing of the V-shaped extrusion block 124 and the V-shaped extrusion block 134, the limiting post 127 and the limiting post 137 can be pulled out from the inside of the through hole 126 and the through hole 136 by pulling the pull ring 128 and the pull ring 138. In this way, the V-shaped extrusion block 124 and the V-shaped extrusion block 134 can be removed and the spacing adjusted. The operation is simple and convenient.

[0026] The fixed structure 13 includes a worktable 131, a second limiting groove 132, a second limiting block 133, a second V-shaped extrusion block 134, a second tooth 135, a second through hole 136, a second limiting post 137, and a second pull ring 138. The bottom of the worktable 131 is fixedly connected to the upper surface of the base 1. Several second limiting grooves 132 are opened on the front outer wall of the worktable 131. The second limiting block 133 is movably connected inside the second limiting groove 132. The second V-shaped extrusion block 134 is fixedly connected to the top of the second limiting block 133. The interior of the second V-shaped extrusion block 134... A toothed bar 135 is fixedly connected. A through hole 136 is provided on the outer right side of the workbench 131. A limiting post 137 is movably connected inside the through hole 136. A pull ring 138 is fixedly connected to one end of the limiting post 137. By adopting the above technical solution, the design of the V-shaped extrusion block 134, the V-shaped extrusion block 124, the toothed bar 135 and the toothed bar 125 can prevent slipping and fix various shapes of steel bar bodies 4 (elliptical, rectangular, square, trapezoidal, etc.), and at the same time improve the stability of the steel bar body 4.

[0027] The outer wall of the king-shaped limiting plate 129 is movably connected to the inside of the limiting hole 7, the connecting hole 8, and the rectangular hole 9. The bottom end of the buffer spring 1210 is fixedly connected to the bottom end of the inner wall of the limiting hole 7. The bottom end of the V-shaped extrusion block 124 is on the same horizontal line as the steel bar body 4. The inside of the through hole 126 is connected to the inside of the limiting groove 122. With the setting of the pressing structure 12, when the hydraulic cylinder 11 drives the movable plate 121 to move downward through the output end, the movable plate 121 is limited inside the limiting hole 7, the connecting hole 8, and the rectangular hole 9 by the king-shaped limiting plate 129, so that the movable plate 121 can only move up and down. This avoids the movable plate 121 from deflecting when it drives the V-shaped extrusion block 124 to move downward. At the same time, while the movable plate 121 and the king-shaped limiting plate 129 are moving, the buffer spring 1210 at the bottom of the king-shaped limiting plate 129 plays a buffering role for the movable plate 121 and the king-shaped limiting plate 129.

[0028] The V-shaped extrusion block 134 contains a steel bar body 4, and the interior of the through hole 136 is connected to the interior of the limiting groove 132. By adopting the above technical solution, the mutual cooperation of the limiting post 127, the limiting groove 132, the through hole 136, the limiting block 133, the V-shaped extrusion block 134, and the limiting post 137 enhances the fixing and limiting effect of the V-shaped extrusion block 124 and the V-shaped extrusion block 134 when the V-shaped extrusion block 124 and the V-shaped extrusion block 134 are extruded to test the steel bar body 4, thereby improving work efficiency.

[0029] In use, the hydraulic cylinder 11 drives the movable plate 121 downward through its output end. Simultaneously, the movable plate 121 is limited within the limiting hole 7, connecting hole 8, and rectangular hole 9 by the king-shaped limiting plate 129, ensuring that the movable plate 121 can only move up and down. This prevents the movable plate 121 from shifting downward when it drives the V-shaped extrusion block 124 downward. Furthermore, as the movable plate 121 and the king-shaped limiting plate 129 move, the buffer spring 1210 at the bottom of the king-shaped limiting plate 129 provides a buffering effect. When the hydraulic cylinder 11 is activated, it drives the movable plate through its output end. Moving 121 downwards causes the movable plate 121 to move while simultaneously driving several V-shaped compression blocks 124 to perform strength tests on multiple parts of the steel bar body 4. This reduces the time wasted on repetitive operations and improves work efficiency. At the same time, by pulling the pull ring 138 and pull ring 128, the limiting post 137 and limiting post 127 are pulled out from the through hole 136 and through hole 126, respectively. Then, the V-shaped compression blocks 134 and V-shaped compression blocks 124 can be adjusted, allowing the device to fix steel bars of different outer diameters and different parts for testing. Therefore, the practicality of the device is improved to a certain extent.

[0030] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
