Description

Technical Field

[0001] This utility model relates to a unidirectional scissor-type internal support orthosis, belonging to the technical field of support devices. Background Technology

[0002] Metal artifact restoration and reshaping is a very important aspect of cultural relic preservation. Its main purpose is to repair deformed metal artifacts, restoring them to their original shape as close as possible while ensuring the authenticity and integrity of the artifacts.

[0003] Generally, for slightly deformed metal artifacts, physical correction can be achieved using hand tools. Tools such as pliers and hammers can be used to carefully tap, stretch, or compress the deformed area to gradually restore its shape. For areas with dents or severe deformation, a support and filling method is required. First, a support is placed inside the deformed area, then it is filled with a suitable material, and finally, a surface treatment is applied to ensure it blends with the surrounding artifact surface.

[0004] In existing technologies, jacks are typically used for internal support when using support filling. However, the expansion limit of a single jack is limited and relatively simple. Furthermore, the internal depth of the artifact being corrected needs to reach a certain level to be fully expanded, making it inconvenient to place the jacks and causing difficulties in the restoration work.

[0005] Therefore, it is necessary to improve the existing technology to overcome the aforementioned defects. Utility Model Content

[0006] The purpose of this invention is to provide a unidirectional scissor-type internal support orthosis with a small operable minimum spacing and easily adjustable opening width.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a unidirectional scissor-type internal support orthosis, comprising:

[0008] Drive lever assembly;

[0009] The support rod assembly, one end of which is rotatably connected to the end of the drive rod assembly; and

[0010] A slider connector is sleeved on the drive rod assembly and rotatably connected to the other end of the support rod assembly;

[0011] The support rod assembly includes a first rod assembly and a second rod assembly symmetrically connected on both sides of the drive rod assembly. The drive rod assembly can drive the slider connector to move along the extension direction of the drive rod assembly, thereby causing the first rod assembly and the second rod assembly to move towards or away from each other.

[0012] Furthermore, the first rod assembly includes a first connecting rod connected to the drive rod assembly and a second connecting rod connected to the slider connector, with the connection between the first connecting rod and the second connecting rod being rotatably connected.

[0013] Furthermore, the second linkage includes a third link connected to the drive linkage and a fourth link connected to the slider connector, wherein the third link and the fourth link are rotatably connected at the connection point.

[0014] Furthermore, the first rod group and the second rod group are provided in two sets, with the first rod group and the second rod group in each set arranged parallel to each other.

[0015] Furthermore, the unidirectional scissor-type internal support orthosis also includes a roller assembly, which is installed at the connection between the first and second links and between the third and fourth links in each group.

[0016] Furthermore, the roller assembly includes a roller component and a shaft component connected to the roller component. The roller component is sleeved on the shaft component, and the connection points of the first connecting rod and the second connecting rod, the third connecting rod and the fourth connecting rod are all connected to both ends of the shaft component.

[0017] Furthermore, the unidirectional scissor-type internal support orthosis also includes a connecting block connected to one end of the drive rod assembly near the support rod assembly. The connecting block is rotatably connected to the drive rod assembly, and the first connecting rod and the third connecting rod are rotatably connected to the connecting block.

[0018] Furthermore, the connecting block has a mounting hole, in which a bearing is installed, and the drive rod assembly is rotatably connected to the connecting block through the bearing.

[0019] Furthermore, the length of the first link is less than the length of the second link, and the length of the third link is less than the length of the fourth link.

[0020] Furthermore, the drive rod assembly has threads, and the slider connector has a threaded hole that matches the threads. The drive rod assembly and the slider connector are threadedly connected through the threads and the threaded hole.

[0021] The beneficial effects of this utility model are as follows: The unidirectional scissor-type internal support orthosis of this utility model is provided with a drive rod group, a support rod group, and a slider connector. The slider connector is sleeved on the drive rod group. One end of the support rod group is rotatably connected to the end of the drive rod group, and the other end is rotatably connected to the slider connector. The support rod group includes a first rod group and a second rod group symmetrically connected on both sides of the drive rod group. The drive rod group can drive the slider connector to move along the extension direction of the drive rod group, thereby driving the first rod group and the second rod group to move towards or away from each other. Thus, the entire support rod group can be extended into the interior of the metal artifact that needs to be corrected through the long drive rod group. Then, the slider connector is driven to move to open the entire support rod group for support. It can penetrate into the interior of the metal artifact to a greater depth, and the adjustment is more convenient, which greatly improves the accuracy and speed of metal artifact restoration.

[0030] Please see Figures 1 to 2 As shown, a unidirectional scissor-type internal support orthosis includes a drive rod assembly 1, a support rod assembly 2, and a slider connector 3 sleeved on the drive rod assembly 1. One end of the support rod assembly 2 is rotatably connected to the end of the drive rod assembly 1, and the other end is rotatably connected to the slider connector 3. The support rod assembly 2 includes a first rod assembly 21 and a second rod assembly 22 symmetrically connected on both sides of the drive rod assembly 1. The drive rod assembly 1 can drive the slider connector 3 to move along the extension direction of the drive rod assembly 1 (here, "movement" refers to reciprocating motion), thereby causing the first rod assembly 21 and the second rod assembly 22 to move towards or away from each other. Thus, when it is necessary to support metal artifacts, the entire support rod assembly 2 can be inserted into the interior of the metal artifact requiring correction through the long drive rod assembly 1. Then, the slider connector 3 is driven to move, thereby opening the entire support rod assembly 2 for support. This allows for deeper insertion into the interior of the metal artifact, and adjustment is more convenient, greatly improving the accuracy and speed of metal artifact restoration.

[0031] Specifically, the first rod group 21 includes a first connecting rod 211 rotatably connected to the drive rod group 1 and a second connecting rod 212 rotatably connected to the slider connector 3. The connection between the first connecting rod 211 and the second connecting rod 212 is rotatably connected. When it is necessary to support the cultural relic, the slider connector 3 moves towards the support rod group 2 under the drive of the drive rod group 1. The second connecting rod 212 drives the first connecting rod 211 to move away from the second rod group 22 under the action of force, so that the connection between the first connecting rod 211 and the second connecting rod 212 is used for support.

[0032] The second rod assembly 22 includes a third connecting rod 221 connected to the drive rod assembly 1 and a fourth connecting rod 222 connected to the slider connector 3. The connection between the third connecting rod 221 and the fourth connecting rod 222 is rotatably connected. Similarly, when support is needed for the artifact, the slider connector 3 moves towards the support rod assembly 2 under the drive of the drive rod assembly 1, and the fourth connecting rod 222, under the action of force, drives the third connecting rod 221 to move away from the first rod assembly 21, thereby using the connection between the third connecting rod 221 and the fourth connecting rod 222 for support. In this embodiment, the length of the first connecting rod 211 is less than the length of the second connecting rod 212, and the length of the third connecting rod 221 is less than the length of the fourth connecting rod 222 to achieve the supporting function.

[0033] In this embodiment, in order to make the support rod group 2 more stable, the first rod group 21 and the second rod group 22 are provided in two sets. The first rod group 21 and the second rod group 22 in each set are arranged in parallel with each other, thereby further increasing the stability during support by setting up double rod groups.

[0034] The unidirectional scissor-type internal support orthosis also includes a roller assembly 4. Roller assemblies 4 are installed at the connections between the first link 211 and the second link 212, and between the third link 221 and the fourth link 222 in each group. The roller assembly 4 includes a roller component 41 and a shaft component 42 connected to the roller component 41. The roller component 41 is sleeved on the shaft component 42 and can rotate relative to the shaft component 42. The connections between the first link 211 and the second link 212, and between the third link 221 and the fourth link 222 are all connected to both ends of the shaft component 42. Therefore, during support, the roller component 41 is used to contact the metal artifact. If uneven force occurs during the support process, the roller component 41 can rotate relative to the contact point with the metal artifact to eliminate uneven force, making the entire support process smoother and preventing damage to the metal artifact.

[0035] In this embodiment, the drive rod assembly 1 has threads, and the slider connector 3 has a screw hole 31 that matches the threads. The drive rod assembly 1 and the slider connector 3 are connected by the threads and the screw hole 31, so that rotating the drive rod assembly 1 can drive the slider connector 3 to move along the extension direction of the drive rod assembly 1.

[0036] It is worth noting that the unidirectional scissor-type internal support orthosis also includes a connecting block 5 connected to one end of the drive rod assembly 1 near the support rod assembly 2. The connecting block 5 is rotatably connected to the drive rod assembly 1, and the first connecting rod 211 and the third connecting rod 221 are rotatably connected to the connecting block 5. The connecting block 5 has a mounting hole 51, in which a bearing is installed. The drive rod assembly 1 is rotatably connected to the connecting block 5 through the bearing, thereby making the rotation process of the drive rod assembly 1 and the connecting block 5 smoother and more stable.

[0037] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
