Detailed Implementation

[0021] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0022] Reference Figure 1 - Figure 5 As shown, this utility model provides a technical solution: a steel bar mechanical property testing device, including a body 1; support columns 2 are provided at the four corners of the top of the body 1, a top plate 3 is fixed to the top of the support columns 2, a hydraulic cylinder 4 is installed on the top of the top plate 3, and a lower pressure block 5 is fixed through the output end of the hydraulic cylinder 4 through the top plate 3; a lifting mechanism is provided on both sides of the top of the body 1, the lifting mechanism includes a fixed frame 6 fixed to both sides of the top of the body 1, a fixed rod 7 is fixed inside the fixed frame 6, two sliders 8 slide on the surface of the fixed rod 7, and a lifting block 9 is fixed to the top of each slider 8, the lifting blocks 9 are arranged in a V-shape relative to each other; a collecting component is provided on the top of the body 1, a protective component is provided at the front end of the body 1, and compression springs 10 are sleeved on the surfaces of both ends of the fixed rod 7; one end of the compression spring 10 is fixed to the inside of the fixed frame 6, and the other end of the compression spring 10 is fixed to the slider 8; the slider 8 has an opening inside that cooperates with the fixed rod 7. The through-hole 11, through the design of the lifting mechanism, enables the device to adapt to steel bars of different diameters, improving the practicality and flexibility of the equipment. During use, when the steel bar is placed on the lifting block 9, since the lifting block 9 is V-shaped and the slider 8 can slide on the fixed rod 7, the lifting block 9 can adaptively adjust according to the diameter of the steel bar, ensuring that the steel bar can be stably lifted. At the same time, the setting of the compression spring 10 further improves the stability of the lifting mechanism, so that when the pressure block 5 is driven by the hydraulic cylinder 4 to perform mechanical property testing on the steel bar, the lifting block 9 can better support the steel bar, avoiding the steel bar shaking and affecting the accuracy of the test results. At the same time, the setting of the collection component facilitates the collection of metal debris generated during the testing process and makes it convenient for users to clean up uniformly. The setting of the protective component further improves the safety of the device, preventing debris from flying and causing injury to the operator.

[0023] Reference Figure 3 As shown in this embodiment, the opposing surfaces of the lifting block 9 are provided with sequentially arranged strip grooves. The design of the strip grooves increases the friction between the lifting block 9 and the reinforcing bar, further improving the stability of the reinforcing bar during the testing process and preventing the reinforcing bar from sliding or falling off during the testing process, thereby ensuring the accuracy of the test results.

[0024] Reference Figure 4 As shown in this embodiment, the collection component includes a collection slot 12 on the top of the body 1, and a collection box 13 is slidably installed inside the collection slot 12. The design of the collection box 13 allows the user to easily clean up the metal debris collected inside the collection slot 12, improving the practicality of the device. At the same time, the sliding installation method makes it very convenient to remove and install the collection box 13.

[0025] Reference Figure 5 As shown in this embodiment: the protective component includes a protective plate 14 fixed to the front end of the body 1. Mounting frames 15 are fixed to both sides of the front end of the body 1. Guide blocks 16 are fixed to both sides of the protective plate 14. A guide groove 17 is provided on the inner side of the mounting frame 15. The protective plate 14 is slidably mounted inside the guide groove 17 via the guide blocks 16. A threaded hole 18 is provided at the front end of the mounting frame 15. A fastening bolt 19 is provided inside the threaded hole 18. One end of the fastening bolt 19 abuts against the guide block 16. Through the design of the protective component, the user can adjust the position of the protective plate 14 according to actual needs. Adjustments were made to ensure that during the testing of the mechanical properties of reinforcing bars, when a reinforcing bar breaks, the protective plate 14 can effectively block flying metal fragments, preventing them from injuring operators and improving the safety of the device. At the same time, the cooperative design of the guide block 16 and the guide groove 17 makes the sliding of the protective plate 14 more stable, avoiding the situation where shaking affects the protective effect, and further improving the stability of the device. The setting of the fastening bolt 19 can fix the guide block 16, ensuring that the protective plate 14 will not be displaced during the testing process, thereby ensuring the safety and accuracy of the test.

[0026] Working Principle: The lifting mechanism is designed to adapt to steel bars of different diameters, improving the practicality and flexibility of the equipment. During use, when the steel bar is placed on the lifting block 9, the V-shaped arrangement of the lifting block 9 and the sliding block 8's ability to slide on the fixed rod 7 allow the lifting block 9 to adaptively adjust to the steel bar's diameter, ensuring stable lifting. The compression spring 10 further enhances the stability of the lifting mechanism, allowing the lifting block 9 to better support the steel bar during mechanical property testing driven by the hydraulic cylinder 4 and the pressure block 5, preventing the steel bar from swaying and affecting the accuracy of the test results. The collection component facilitates the collection of metal debris generated during testing, allowing for convenient cleaning by the user. The protective component further enhances the safety of the device, preventing debris from flying and injuring operators. The grooved design increases the friction between the lifting block 9 and the steel bar, further improving the stability of the steel bar during testing. The design of the collection box 13 prevents the steel bars from slipping or falling off during the testing process, thus ensuring the accuracy of the test results. The collection box 13 allows users to easily clean the metal debris collected inside, improving the device's practicality. The sliding installation method makes the collection box 13 easy to remove and install. The protective components allow users to adjust the position of the protective plate 14 according to actual needs. During the steel bar mechanical property testing process, when the steel bar breaks, the protective plate 14 effectively blocks flying metal debris, preventing injury to operators and improving the device's safety. The coordinated design of the guide block 16 and guide groove 17 makes the sliding of the protective plate 14 smoother, preventing shaking from affecting the protective effect and further improving the device's stability. The fastening bolts 19 fix the guide block 16, ensuring that the protective plate 14 does not shift during the testing process, thus guaranteeing the safety and accuracy of the test.

[0027] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
