Description

Technical Field

[0001] This utility model relates to the field of test protection and recycling technology, and in particular to a detachable Hopkinson bar test protection and recycling box. Background Technology

[0002] In recent years, research on the dynamic mechanical properties of materials has played a vital role in armor protection, aerospace, and civil engineering. Currently, the split Hopkinson bar testing system is widely used to study materials with high strain rates (10⁻⁶ Ω·cm). 2 ~10 4 s -1 The dynamic mechanical behavior under extreme load conditions provides key support for the performance evaluation of materials.

[0003] The Hopkinson bar test protection and collection device proposed in Chinese patent CN217931102U achieves multiple functions such as optimized sample positioning, high-speed photography compatibility, efficient fragment recovery, and safety protection through an innovative design that integrates a lifting platform, protective box, collection box, and observation window.

[0004] The aforementioned patent can be used for the collection and protection of debris from Hopkinson bar tests. However, the installation process is rather cumbersome, and the lifting platform and protective box are connected by screws, resulting in a complex structure that increases the difficulty of replacement and installation, reducing the overall practicality and convenience. In addition, the position adjustment via the lifting cylinder provides relatively rigid support for the test specimen, which may affect the destructive process of the test specimen under load. Summary of the Invention

[0005] In view of this, the purpose of this utility model is to propose a separate Hopkinson bar test protective recovery box to solve the problem that the current recovery box has a complex structure and provides relatively rigid support for the test piece, which affects the loading and failure process of the test piece.

[0006] To achieve the above objectives, this utility model provides a detachable Hopkinson bar test protective recovery box, including a box body and a support mechanism disposed within the box body, wherein: The support mechanism includes a base disposed within the housing, a first connecting rod disposed on the base and universally connected to the base at one end, a rotating sleeve fixedly disposed on the first connecting rod, a second connecting rod sleeved within the rotating sleeve, and a tray disposed on the top of the second connecting rod and universally connected to the second connecting rod. The support mechanism can support the test piece on the tray through the frictional force of the connection parts.

[0007] Optionally, one side of the box body is provided with a first opening for inserting an incident rod, and the other side of the box body is provided with a second opening for inserting a transmission rod, wherein the diameter of the first opening is larger than the diameter of the second opening.

[0008] Optionally, the recycling box further includes a calibration mechanism, which includes an arc-shaped component snapped onto the incident rod, with a calibration head located at the center of the arc-shaped component, and the calibration head being coaxial with the incident rod.

[0009] When it is necessary to align the test piece on the tray between the incident rod and the transmission rod, the arc-shaped piece is snapped into one end of the incident rod. At this time, the calibration head is coaxial with the incident rod and the transmission rod. Then, the center of the test piece is aligned with the calibration head, so that the center of the test piece is coaxial with the incident rod and the transmission rod. The design of the calibration mechanism allows for a more intuitive and clear adjustment of the test piece to the appropriate position.

[0010] Optionally, the front side of the housing has a removable viewing window.

[0011] Optionally, the viewing window can be detached by providing a first slot on both sides of the viewing window and a second slot on both sides of the box body that mates with the first slot.

[0012] Optionally, the observation window is made of bulletproof glass or acrylic sheet.

[0013] Optionally, the box body is made of steel. The base is a strong magnetic base. Through the magnetic connection between the strong magnetic base and the bottom of the box body, the support mechanism can be quickly installed in the desired location.

[0014] Optionally, the seat body is connected to the first link via a ball joint universal joint, and the second link and the tray are connected via a ball joint universal joint.

[0015] Optionally, the top of the box has a cover plate, one side of which is rotatably connected to one side of the box via a hinge.

[0016] When using this recycling box, the test piece is placed on the tray, and then the positions of the first link, the second link, and the tray are adjusted so that the test piece moves to the appropriate position. As can be seen from the above, this utility model has a simple structure, reduces the difficulty of replacement and installation, and improves the overall practicality and convenience. At the same time, through the relatively flexible support of friction, the tray will move under a large force, thereby reducing the impact on the loading and damage process of the test piece.

[0022] like Figure 1 and Figure 2 As shown, a detachable Hopkinson's compression bar test protective recovery box includes a box body 1, optionally, the box body 1 is composed of a steel square box 2, and further includes: a support mechanism disposed within the box body 1, wherein: The support mechanism includes a seat 10 disposed inside the housing 1, a first connecting rod 11 disposed on the seat 10 and universally connected to the seat 10 at one end, a rotating sleeve 12 fixedly disposed on the first connecting rod 11, a second connecting rod 13 sleeved inside the rotating sleeve 12, and a tray 14 disposed on the top of the second connecting rod 13 and universally connected to the second connecting rod 13. This support mechanism can support the test piece on the tray 14 through the friction of the connection parts.

[0023] When using this recycling box, the test piece is placed on the tray 14, and then the positions of the first connecting rod 11, the second connecting rod 13, and the tray 14 are adjusted so that the test piece moves to the appropriate position. As can be seen from the above, this utility model has a simple structure, reduces the difficulty of replacement and installation, and improves the overall practicality and convenience. At the same time, through the relatively flexible support of friction, the tray 14 will move under a large force, thereby reducing the impact on the loading and damage process of the test piece.

[0024] like Figure 3 As shown, in some embodiments, one side of the box body 1 is provided with a first opening 4 for passing through an incident rod, and the other side of the box body 1 is provided with a second opening 5 for passing through a transmission rod. The diameter of the first opening 4 is larger than the diameter of the second opening 5. The design that the diameter of the first opening 4 is larger than the diameter of the second opening 5 makes the installation of the recycling box more convenient.

[0026] When it is necessary to align the test piece on tray 14 between the incident rod and the transmission rod, the arc-shaped part 15 is snapped into one end of the incident rod. At this time, the calibration head 16 is coaxial with the incident rod and the transmission rod. Then, the center of the test piece is aligned with the calibration head 16, so that the center of the test piece is coaxial with the incident rod and the transmission rod. The design of the calibration mechanism allows for a more intuitive and clear adjustment of the test piece to the appropriate position.

[0027] With the development of imaging technology, DIC (Discrete Integrated Circuit) technology is widely used in the study of the dynamic mechanical behavior of materials. Therefore, the split Hopkinson bar test protective recovery box not only needs to provide protection and recover the sample during the test, but also sometimes needs to meet the requirements of high-speed photography.

A high-speed camera can be placed outside the observation window 8 to ensure both high-speed photography and the safety of the camera.

[0028] In some embodiments, the observation window 8 is detachable by providing first slots 9 on both sides of the observation window 8 and second slots 3 on both sides of the housing 1 that mate with the first slots 9. This interlocking connection enables rapid installation and disassembly, improving work efficiency.

[0029] In some embodiments, the base 10 is a powerful magnetic base. Through the magnetic connection between the powerful magnetic base and the bottom of the housing 1, the support mechanism can be quickly installed in the desired location.

[0030] In some embodiments, the seat 10 is connected to the first link 11 via a ball joint universal joint, and the second link 13 and the tray 14 are connected via a ball joint universal joint.

[0031] like Figure 3 As shown, in some embodiments, the top of the housing 1 has a cover plate 6, one side of which is rotatably connected to one side of the housing 1 via a hinge 7. Opening the cover plate 6 allows personnel to have a clearer view inside the housing 1, thus facilitating the adjustment and installation of the test piece.

[0032] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of the present invention (including the claims) is limited to these examples; within the framework of the present invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in the details for the sake of brevity.

[0033] This utility model is intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
