Description

Technical Field

[0001] The utility model relates to the technical field of impact experiments, in particular to a semi-automatic impact testing machine which is convenient for taking out samples. Background Art

[0002] Impact testing is generally a test method to determine the safety, reliability and effectiveness of military and civilian equipment when subjected to external impact or action. A pressure is gradually applied to the test object. When the pressure reaches the limit of the test object's pressure resistance, the pressure is used to measure the test object's pressure resistance value.

[0003] After searching the Chinese patent with the authorization announcement number CN217211855U, a semi-automatic impact testing machine is disclosed, which belongs to the field of impact experiment technology, including a protection box, a fixed plate is installed on one side of the protection box, a pushing hydraulic rod is installed on the upper surface of the fixed plate, a sliding plate is installed on the telescopic end of the pushing hydraulic rod, and a baffle is installed on the side of the sliding plate away from the pushing hydraulic rod, and the baffle is clamped on one side of the protection box. This semi-automatic impact testing machine, through the cooperation of the protection box, the impact hydraulic rod, the upper top plate, the baffle, the pressure column, the clamping ring, the sliding plate, the pushing hydraulic rod and the fixed plate, can make the semi-automatic impact testing machine convenient for testing the test object and protect the personal safety of the people watching the test. The power provided by the pushing hydraulic rod is used to move the test object, so as to achieve the purpose of conveniently using the device for impact testing, and the upper top plate and the pressure column are driven downward by the impact hydraulic rod to prevent the debris in the protection box from jumping out and injuring people.

[0004] Based on the above search and combined with the prior art, we found that:

[0005] Although the above technology can prevent the debris in the protective box from jumping out and injuring people, it is difficult to take out all the fragments after the sample is broken into a large number of fragments inside the protective box, which is time-consuming, labor-intensive and inconvenient to use. Utility Model Content

[0006] In order to solve the above technical problems, the utility model proposes a semi-automatic impact testing machine which is convenient for taking out samples, thereby preventing the samples from being broken and making it easy to take out samples.

[0007] The technical solution to achieve the purpose of the utility model is: a semi-automatic impact testing machine that is easy to take out samples, including a fuselage, a mounting frame is fixedly installed on the fuselage, a hydraulic rod is embedded in the mounting frame, an extrusion plate is fixedly installed on the output end of the hydraulic rod, the extrusion plate is located above the interior of the fuselage, an inner cavity is opened on the side wall of the fuselage, a storage box is movably installed inside the inner cavity, a partition is vertically fixed inside the storage box, a torsion spring shaft is movably installed at the bottom of the storage box, a bottom plate is fixedly sleeved on the torsion spring shaft, a torsion spring shaft is also movably installed on the top of the partition, a movable plate is fixedly sleeved on the torsion spring shaft, and a sealing strip is fixedly installed above the position of the torsion spring shaft inside the storage box.

[0008] In some embodiments, a limit groove is provided on the inner wall of the fuselage, a limit strip is movably installed on the movable plate, one end of the limit strip is located inside the limit groove, and a return spring connected to the limit strip is installed inside the movable plate.

[0009] In some embodiments, a slide groove is provided inside the body, and a slide bar located inside the slide groove is fixedly installed on the bottom of the storage box.

[0010] In some embodiments, a mounting groove is provided at the bottom of the extrusion plate, an impact head is provided at the bottom of the extrusion plate, one end of the impact head is located inside the mounting groove, a fixed groove is provided on the impact head, a movable groove is provided at a position corresponding to the fixed groove on the bottom wall of the extrusion plate, a limit rod is movably installed inside the movable groove, one end of the limit rod is located inside the fixed groove, and a mounting spring connected to the limit rod is installed inside the movable groove.

[0011] Compared with the prior art, the present invention has the following significant advantages:

[0012] In the utility model, the sealing strip can limit the bottom plate so that the bottom plate cannot be turned over upwards. The top of the partition is also fixedly installed with a sealing strip near the inside. The sealing strip can limit the movable plate so that the movable plate cannot be turned over inwards. When performing an impact test, first turn the movable plate outwards and place the sample inside the storage box. The sample is placed on the bottom plate, and the bottom plate is located inside the storage box. The bottom plate is limited and cannot be turned over downwards. Then start the hydraulic rod, and the hydraulic rod will drive the extrusion plate downwards to perform an impact test on the sample. At the same time, the sample is located inside the storage box, so that the sample will not splash around when it is broken. When the experiment is completed, the storage box can be pulled out of the fuselage. When the storage box is pulled out of the fuselage, the bottom plate loses the limit of the fuselage, and the bottom plate will turn downwards. At this time, the sample on the bottom plate will fall along the inclined surface of the bottom plate, thereby preventing the sample from being broken and facilitating the removal of the sample.

[0013] The problem of difficult removal of broken samples is solved. BRIEF DESCRIPTION OF THE DRAWINGS

The bottom of the storage box 6 is movably installed with a torsion spring shaft 8 below. The torsion spring shaft 8 is a cylindrical structure. A bottom plate 9 is fixedly sleeved on the torsion spring shaft 8. The bottom plate 9 is a rectangular structure plate. The top of the partition 7 is also movably installed with a torsion spring shaft 8. A movable plate 10 is fixedly sleeved on the torsion spring shaft 8. The movable plate 10 is a rectangular structure plate. A sealing strip 11 is fixedly installed above the position of the torsion spring shaft 8 in the storage box 6. The sealing strip 11 is a curved surface. The sealing strip 11 can limit the bottom plate 9 so that the bottom plate 9 cannot be turned up. The top of the partition 7 is also fixedly installed with a sealing strip 11 near the inside. The sealing strip 11 can limit the movable plate 10 so that the movable plate 10 cannot be turned inward. When performing an impact test, first flip the movable plate 10 outward, place the sample in the storage box 6, and place the sample on the bottom plate 9. The bottom plate 9 is located in the storage box 6. The bottom plate 9 is limited and cannot be turned down. Then start the hydraulic rod 3, and the hydraulic rod 3 will drive the extrusion plate 4 downward to perform an impact test on the sample. At the same time, the sample is located in the storage box 6, so that the sample will not splash around when it is broken. When the experiment is completed, the storage box 6 can be pulled out of the fuselage 1. After the storage box 6 is pulled out of the fuselage 1, the bottom plate 9 loses the limit of the fuselage 1, and the bottom plate 9 will turn downward. At this time, the sample on the bottom plate 9 will fall along the inclined surface of the bottom plate 9, thereby preventing the sample from being broken and facilitating the removal of the sample.

The top of the partition 7 near the inner position is also fixedly installed with a sealing strip 11. The sealing strip 11 can limit the movable plate 10 so that the movable plate 10 cannot be turned inward. When performing an impact test, first flip the movable plate 10 outward, place the sample in the storage box 6, and place the sample on the bottom plate 9. The bottom plate 9 is located in the storage box 6. The bottom plate 9 is limited and cannot be turned down. Then start the hydraulic rod 3, and the hydraulic rod 3 will drive the extrusion plate 4 downward to perform an impact test on the sample. At the same time, the sample is located in the storage box 6, so that the sample will not splash around when it is broken.
