Description

Technical Field

[0001] The utility model relates to the technical field of universal testing machines, in particular to a universal testing machine with a safety protection device. Background Art

[0002] Universal testing machine, a material testing machine integrating tensile, bending, compression, shearing, ring stiffness and other functions, is mainly used for mechanical property testing of metal and non-metallic materials. It is an ideal testing equipment for industrial and mining enterprises, scientific research institutions, colleges and universities, engineering quality supervision stations and other departments.

[0003] Publication No. CN207779806U discloses a universal testing machine, comprising: a testing machine body, a lower pressing plate provided on the testing machine body, a material receiving tube provided on the testing machine body and connected to the lower pressing plate, a material receiving box for collecting waste material detachably assembled with the material receiving tube, and a first locking assembly for locking or unlocking the material receiving box and the material receiving tube. The universal testing machine provided by the utility model collects waste material on the lower pressing plate through a material receiving box detachably assembled on the material receiving tube, so that the operator only needs to dump the waste material in the material receiving box after the material receiving box is full, without having to clean the ground again, making the cleaning of waste material easier. Although the universal testing machine improves the cleaning efficiency of the staff through the detachable collection box, the staff only needs to dump the waste in the collection box after it is full, and there is no need to sweep the ground again, making the cleaning of waste easier. However, the universal testing machine is not equipped with a safety protection device. During the test, the material may not be able to withstand the test and cause the material to break and break. The broken material will generally splash or be thrown out, posing a safety hazard to the test personnel and the laboratory, which needs to be improved. Utility Model Content

However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0024] Embodiment 1

[0025] See also Figure 1-5 The utility model provides a technical solution: a universal testing machine with a safety protection device, including a base 1, a support column 2 is fixedly installed at the bottom end of the base 1, a fixed cover 3 is fixedly installed at the end of the base 1 away from the support column 2, a slide groove 16 is opened on the surface of the base 1, a movable cover 4 is fixedly installed inside the slide groove 16, a baffle B6 is fixedly installed on the top of the fixed cover 3, a baffle A5 is fixedly installed on the side of the movable cover 4 away from the baffle B6, a motor 8 is fixedly installed inside the base 1, a threaded rod 9 is installed at the output end of the motor 8, a movable plate 10 is sleeved on the surface of the threaded rod 9, and a cylinder 7 is penetrated at the end of the movable plate 10 away from the threaded rod 9.

[0026] See also Figure 4-5The movable plate 10 is threadedly connected with the threaded rod 9, and the movable plate 10 is slidably connected with the cylinder 7. The rotation of the threaded rod 9 drives the movable plate 10 to slide up and down along the cylinder 7, and the height of the movable plate 10 is adjusted. The specifications of the movable cover 4 and the slide groove 16 match each other. The movable cover 4 and the slide groove 16 are slidably connected. Closing the movable cover 4 can avoid the splashing of debris generated during detection, which is safer. The shape of the slide groove 16 is "T"-shaped, and the "T"-shaped slide groove 16 is more solid, and the movable cover 4 is not easy to fall off.

[0027] Embodiment 2

[0028] See also Figure 2-3 A connecting plate 14 is fixedly installed at one end of the movable plate 10 close to the base 1, and a card slot 11 is opened on the surface of the connecting plate 14. A card block 13 is fixedly installed inside the card slot 11, and a spring 12 is fixedly installed between the card blocks 13. A pressure plate 15 is fixedly installed at one end of the card block 13 away from the connecting plate 14, which can be removed and replaced with a pressure plate 15 of different sizes. The card block 13 is snap-connected with the card slot 11, and the card slot 11 cooperates with the card block 13 to fix the connecting plate 14 and the pressure plate 15 together. The card slots 11 are distributed in an array on the surface of the connecting plate 14. The setting of multiple groups of card slots 11 makes the connection between the connecting plate 14 and the pressure plate 15 more firmly.

[0029] Working principle: When using the universal testing machine, first replace the pressure plate 15 of different specifications according to the needs, the staff squeezes the block 13 to the spring 12 to make the spring 12 produce elastic deformation, then pull the pressure plate 15 outward to release the fixation between the pressure plate 15 and the connecting plate 14, and then install the pressure plate 15 of matching specifications. The whole process is simple and easy, and no tools are required, which greatly improves the convenience of using the equipment. Then, the material to be tested is placed between the fixed cover 3 and the movable cover 4, and the movable cover 4 on the left and right sides is closed. When the movable cover 4 moves to the appropriate position, the baffle B6 contacts the baffle A5 to limit the movable cover 4 to prevent it from moving further, so that the fixed cover 3 and the movable cover 4 form a closed protective cover to avoid the debris generated during the test from splashing onto the staff, thereby improving the safety of the universal testing machine. After the movable cover 4 is closed, the motor 8 is started, and the threaded rod 9 is driven by the motor 8 to rotate, so that the movable plate 10 moves up and down along the cylinder 7 to start the detection work.
