DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

[0025] The embodiment of the present application provides a reusable model device, including a base 1 and a sliding part 3. The base 1 is provided with a first slide rail. The sliding part 3 is slidably connected to the first slide rail, and the sliding part 3 is provided with a plurality of wall parts 4, the plurality of wall parts 4 enclose a limiting space, and the wall parts 4 are threadedly connected with clamping bolts 5, and the plurality of clamping bolts 5 cooperate to clamp the experimental piece 7.

[0026] The model device of the embodiment of the present application can be used to clamp a hollow long strip experimental piece 7, such as a tube or a hollow rod.

[0027] There can be multiple sliding parts 3. The sliding parts 3 are slidably connected to the first slide rail, so that the position of the sliding part 3 relative to the base 1 can be adjusted, and then the intervals between the multiple sliding parts 3 can also be adjusted.

[0028] The limiting space enclosed by the wall portions 4 is used to limit the experimental piece 7 , so that the multiple wall portions 4 can fix the experimental piece 7 .

[0029] The clamping bolt 5 may directly abut against the test piece 7 to clamp the test piece 7, or the clamping bolt 5 may indirectly clamp the test piece 7 via other components.

[0030] The test piece 7 is fixed to the sliding part 3 by the clamping bolt 5 so that the model device can clamp the test piece 7. By providing a plurality of sliding parts 3, a plurality of test pieces 7 can be arranged in parallel.

[0031] In the embodiment of the present application, the wall portion 4 may be an arc-shaped structure, so as to facilitate fixing the test piece 7 having a circular cross-section.

[0032] In some embodiments, the base 1 is further provided with two strip-shaped portions 2, and the two strip-shaped portions 2 are arranged at intervals to form a first slide rail.

[0033] The sliding portion 3 is disposed between the two strip portions 2 , so that the sliding portion 3 can be limited by the two strip portions 2 , so that the sliding portion 3 can be slidably connected to the base 1 .

[0034] The strip portion 2 may be connected to the base 1 by bolts.

[0035] In some embodiments, the strip portion 2 includes a first segment 9 and a second segment 10 , the first segment 9 is connected to the base 1 , and the second segment 10 is disposed on opposite sides of the two first segments 9 .

[0036] The first section 9 can be connected to the base 1 by bolts.

[0037] The first segment 9 and the second segment 10 form a bent structure, and the sliding portion 3 is partially disposed between the two first segments 9 and partially disposed between the second segments 10 , so that the sliding portion 3 will not be separated from the base 1 .

[0038] In some embodiments, the sliding portion 3 is further threadedly connected with a limiting bolt 8 , and the limiting bolt 8 abuts against the base 1 .

[0039] By turning the limit bolt 8, the limit bolt 8 can be tightly pressed against the base 1, and the position of the sliding part 3 relative to the base 1 can be locked. On the contrary, by rotating the limit bolt 8 in the opposite direction, the limit bolt 8 no longer presses against the base 1, and the sliding part 3 can be unlocked.

[0040] In some embodiments, a plurality of pads 6 are further included. The pads 6 are used to be arranged around the circumference of the test piece 7 , and the clamping bolts 5 abut against the pads 6 to clamp the test piece 7 .

[0041] The pad 6 is arranged inside the wall 4. When the clamping bolt 5 is rotated to move into the limiting space, the clamping bolt 5 abuts against the pad 6, and the pad 6 closes to clamp the test piece 7. The risk of the test piece 7 being damaged by pressure can be reduced by providing the pad 6.

[0042] The pad portion 6 can be arranged in a one-to-one correspondence with the wall portion 4 .

[0043] In some embodiments, multiple wall portions 4 are arranged around a reference axis, and the wall portion 4 includes a first wall 17 close to the inner side. The first wall 17 is inclined so that the side of the limiting space away from the sliding portion 3 is expanded. The first wall 17 is provided with a second slide rail 12 extending along the reference axis. The second slide rail 12 is slidably connected with a clamping portion 13, and the clamping bolt 5 is used to drive the clamping portion 13 to move toward the sliding portion 3.

[0044] The reference axis may be the axis shown as the Z axis in the figure.

[0045] For example, the limiting space may be in a frustum shape, with the small diameter side of the limiting space close to the sliding portion 3 and the large diameter side away from the sliding portion 3 .

[0046] It should be noted that when the second slide rail 12 extends along the reference axis, since the first wall 17 is inclined, the second slide rail 12 also extends inclinedly.

[0047] When the clamping parts 13 move toward the sliding part 3, the distance between the clamping parts 13 is reduced, so that the test piece 7 can be clamped. Conversely, when the clamping parts 13 move away from the sliding part 3, the distance between the clamping parts 13 is increased, making it easier to take and place the test piece 7.

[0048] In some embodiments, the wall portion 4 is movably provided with a driving portion 11, the moving direction of the driving portion 11 is perpendicular to the reference axis, the driving portion 11 abuts against the clamping portion 13, the abutting surfaces of the driving portion 11 and the clamping portion 13 are inclined surfaces, the clamping bolt 5 is rotatably connected to the driving portion 11, and the clamping portion 13 is also provided with a first elastic member 16, which connects the clamping portion 13 and the wall portion 4 so that the driving portion 11 remains abutted against the clamping portion 13.

[0049] The abutting surfaces of the driving part 11 and the clamping part 13 are inclined surfaces, so that the clamping part 13 can be driven to move by the driving part 11. For example, when the driving part 11 moves toward the reference axis, the driving part 11 can push the clamping part 13 to move toward the sliding part 3.

[0050] The structure of the movable connection between the driving part 11 and the wall part 4 can be selected from existing structures and will not be described in detail here.

[0051] The clamp bolt 5 is rotatably connected to the driving portion 11 , and the clamp bolt 5 is threadedly connected to the wall portion 4 , so that the driving portion 11 can be driven to move by rotating the clamp bolt 5 .

[0052] The first elastic member 16 may be a spring.

[0053] The elastic restoring force of the first elastic member 16 enables the clamping portion 13 to remain against the driving portion 11 .

[0054] In some embodiments, the clamping portion 13 is further provided with a supporting portion 15 movably disposed on the clamping portion 13 along the line connecting the reference axis and the clamping portion 13 , and a limiting portion 14 is disposed on one side of the supporting portion 15 close to the reference axis.

[0055] The clamping portion 13 may be provided with a sliding groove, and the support portion 15 may be inserted into the sliding groove, so that the support portion 15 can move relative to the clamping portion 13 .

[0056] A second elastic member may be provided between the support portion 15 and the wall portion 4 , and the second elastic member may be used to provide an elastic force for moving the limiting portion 14 in a direction away from the wall portion 4 .

[0057] The support portion 15 is used to support the test piece 7. If the moving direction of the clamping portion 13 is parallel to the reference axis, the disadvantage of such a setting is that when the test piece 7 is large in size, it may be necessary to apply force to the test piece 7 before the test piece 7 can be inserted between the clamping portions 13, which makes the operation inconvenient on the one hand and increases the risk of damage to the test piece 7 on the other hand.

[0058] In the embodiment of the present application, in the initial state, the spacing between the clamping parts 13 is large, which facilitates the placement of the experimental piece 7 between the clamping parts 13. At the same time, the experimental piece 7 can be supported by the supporting part 15, so that the position of the experimental piece 7 relative to the clamping part 13 can be fixed. When the clamping parts 13 are closed, the clamping parts 13 can simultaneously drive the experimental piece 7 to move in the direction close to the sliding part 3, making the operation more convenient and ensuring that the depth of the experimental piece 7 inserted into the limiting space is consistent.

[0059] On the one hand, the limiting part 14 is used to limit the position of the experimental piece 7. For example, when the experimental piece 7 is a hollow structure, the limiting part 14 can be set inside the experimental piece 7, reducing the risk of detachment from the sliding part 3 in the initial state. On the other hand, the limiting part 14 is used to limit the movement stroke of the clamping part 13. When the clamping part 13 moves a certain distance toward the sliding part 3, the limiting parts 14 close and abut against each other, so that the clamping part 13 cannot move further toward the sliding part 3, reducing the risk of excessive clamping force of the clamping part 13 on the experimental piece 7 and damaging the experimental piece 7. On the other hand, the limiting part 14 can also support the experimental piece 7. The limiting part 14 is set inside the experimental piece 7, and the inner wall of the experimental piece 7 is supported by the limiting part 14, which can reduce the risk of deformation of the experimental piece 7 under pressure.

[0060] In some embodiments, the limiting portion 14 includes a mounting seat 22, a contact portion 19, and an elastic wall 18. The mounting seat 22 is connected to the support portion 15, and the contact portion 19 is disposed on a side of the mounting seat 22 close to the wall portion 4. The elastic wall 18 is configured to be curved, and the convex side of the elastic wall 18 is connected to the mounting seat 22, and the contact portion 19 includes a second wall 21 facing the mounting seat 22, and the contact portion 19 is provided with a sliding groove 20 extending along its length direction, and the sliding groove 20 is provided with an opening in the second wall 21, and the end of the elastic wall 18 is inserted into the sliding groove 20 via the opening.

[0061] The mounting seat 22 can be connected to the support portion 15 in an adjustable manner, so that the position of the mounting seat 22 relative to the limiting portion 14 can be adjusted. The specific connection structure of the mounting seat 22 and the support portion 15 can be selected from existing structures and will not be repeated here.

[0062] The contact portion 19 is used to contact the inner wall surface of the test piece 7. In order to increase the contact area, the contact portion 19 can be set as an arc-shaped plate structure. In this embodiment, the length direction of the contact portion 19 can be the arc length direction of the contact portion 19.

[0063] The elastic wall 18 is made of elastic material.

[0064] The elastic wall 18 is curved, and the convex side of the elastic wall 18 is connected to the mounting seat 22, which increases the distance between the contact portion 19 and the mounting seat 22 so that the contact portion 19 can be as close to the test piece 7 as possible. On the other hand, the elastic deformation amplitude of the elastic wall 18 is increased.

[0065] The end of the elastic wall 18 is inserted into the sliding groove 20, so that the contact portion 19 can be connected to the mounting seat 22 through the elastic wall 18. On the other hand, when the contact portion 19 is subjected to pressure toward the mounting seat 22, the length of the elastic wall 18 inserted into the sliding groove 20 can be increased, so that the elastic wall 18 can be deformed, and then the contact portion 19 can be close to the mounting seat 22. Compared with the traditional connection through a spring, this structure can ensure the connection strength between the contact portion 19 and the mounting seat 22.

[0066] Under the action of the elastic wall 18, the position of the contact portion 19 relative to the mounting seat 22 can float within a certain range, so that when the clamping portion 13 moves relative to the wall portion 4, the contact portion 19 can remain against the inner wall of the experimental piece 7, thereby increasing the limiting effect on the experimental piece 7. At the same time, when the clamping portion 13 applies pressure to the outer wall of the experimental piece 7, the contact portion 19 can support the inner wall of the experimental piece 7, thereby reducing the risk of deformation of the experimental piece 7.

[0067] In some embodiments, a plurality of connection holes are provided at intervals on the elastic wall 18 along the length direction of the elastic wall 18 , and the elastic wall 18 is connected to the mounting seat 22 by bolts passing through the connection holes.

[0068] The length direction of the elastic wall 18 may be the arc length direction of the elastic wall 18 .

[0069] For example, the connection holes may be arranged in multiple rows and columns in the length and width directions of the elastic wall 18 .

[0070] The elastic wall 18 is connected to the mounting seat 22 by bolts, which increases the connection reliability between the elastic wall 18 and the mounting seat 22. On the other hand, since the connection holes are set to be multiple, the bolts can also be set to be multiple. By selecting the connection holes through which the bolts are inserted, the spacing between the bolts can be adjusted, and then the curvature of the elastic wall 18 can be adjusted, making the disassembly and assembly between the elastic wall 18 and the contact portion 19 more convenient. Specifically, in the initial state, the end of the elastic wall 18 can be inserted into the opening, and then multiple bolts are passed through the connection holes and threadedly connected to the mounting seat 22. As the bolts are screwed in, the curvature of the elastic wall 18 decreases, and the length of the elastic wall 18 inserted into the sliding groove 20 increases, and the contact portion 19 cannot be detached from the elastic wall 18. On the contrary, when the contact portion 19 needs to be disassembled, the bolts are loosened, and the curvature of the elastic wall 18 increases, and the elastic wall 18 gradually withdraws from the sliding groove 20, and the contact portion 19 can be disassembled from the elastic wall 18.

[0071] The above embodiments are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations, modifications, and substitutions made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
