[0031] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0032] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in, Figure 1 A schematic diagram of a preferred embodiment of the tensile testing device for building engineering testing provided by this utility model; Figure 2 for Figure 1 The front sectional view shown is illustrated. Figure 3 for Figure 2 The enlarged schematic diagram of part A shown below; Figure 4 for Figure 3The diagram shown is a partial exploded view. The tensile testing device for building engineering testing includes: a tensile body 1, a support frame 11 at the top of the tensile body 1, a telescopic component 12 at the bottom of the support frame 11, two sets of receiving boxes 13 on the tensile body 1, one set of receiving boxes 13 installed at the top of the tensile body 1, and the other set of receiving boxes 13 installed at the bottom of the telescopic component 12, a driving component 14 outside each receiving box 13, the driving component 14 penetrating the receiving box 13 and extending into its interior, two symmetrically slidingly connected moving blocks 15 inside each receiving box 13, the interiors of the two moving blocks 15 threadedly connected to the exterior of the driving component 14, and a steering assembly 2 inside each of the two moving blocks 15. The component 2 includes a receiving groove 21, which is formed inside the movable block 15. A vertical rod 22 is slidably connected inside the receiving groove 21, passing through the movable block 15 and extending to its outside. The outside of the vertical rod 22 is slidably connected to the inside of the movable block 15. A slot 23 is formed at the top of the inner wall of the receiving groove 21. An insert block 24 is fixedly connected to the top of the vertical rod 22. The inside of the slot 23 is inserted into the outside of the insert block 24. An anti-disengagement ring 25 is fixedly connected to the outside of the vertical rod 22. An elastic element 26 is sleeved on the outside of the vertical rod 22. A mounting plate 27 is fixedly connected to the bottom of the vertical rod 22. A flat clamping member 28 and an arc-shaped clamping member 29 are respectively provided at the bottom of the mounting plate 27.

[0033] The support frame 11 provides the mounting base for each part. The telescopic component 12 is used to control the height adjustment of a set of receiving boxes 13. The receiving boxes 13 are divided into two groups, one movable and one fixed. The movable receiving box 13 is installed at the bottom of the telescopic component 12, and the fixed receiving box 13 is installed at the top of the tension body 1. The internal components, parts and structures of the two sets of receiving boxes 13 have the same working principle. The drive component 14 enables the two moving blocks 15 to move towards or away from each other, which facilitates the clamping of materials and provides suitable space. The drive component 14 is a motor and a bidirectional screw structure. The motor is installed outside the receiving box 13, and the bidirectional screw is installed at the output end of the motor. The two moving blocks 15 are installed outside the bidirectional screw and are threadedly connected. The steering component 2 is set inside the moving block 15 to facilitate adjustment to a similar shape according to the shape of the object being clamped. The flat clamping component 28 is used to clamp materials with flat shapes, and the arc-shaped clamping component 29 is used to clamp materials with arc-shaped surfaces. The two are quickly switched by the vertical rod 22.

[0034] The receiving groove 21 is provided with a guide component 3. The guide component 3 includes two guide blocks 31 and four slide grooves 32. The two guide blocks 31 are symmetrically installed on the inner wall of the receiving groove 21, and the four slide grooves 32 are arranged in a circumferential array on the outside of the anti-detachment ring 25.

[0035] The guide block 31 and the slide groove 32 provide a guiding basis for the vertical movement of the vertical rod 22. Specifically, when the vertical rod 22 moves downward, the anti-detachment ring 25 moves synchronously. When the slide groove 32 on the anti-detachment ring 25 disengages from the guide block 31, the vertical rod 22 is turned from 0 degrees to 180 degrees. At this time, the guide block 31 coincides with two of the four slide grooves 32, releasing the vertical rod 22. At this time, the elastic element 26 on the vertical rod 22 releases pressure and drives the anti-detachment ring 25 to move upward, so that the insertion block 24 is re-inserted into the slot 23. The guide assembly 3 provides stable support for its movement.

[0036] Both of the movable blocks 15 are provided with locking components 4 on their exteriors. Each locking component 4 includes a reset component 41 and four insertion holes 42. The reset component 41 is installed on the exterior of the movable block 15, and the four insertion holes 42 are respectively opened around the perimeter of the plug block 24. The exterior of the reset component 41 is inserted into the interior of the insertion holes 42.

[0037] By engaging the reset piece 41 with the insertion holes 42 around the insertion block 24, the rotational position of the vertical rod 22 can be effectively locked. This ensures that the planar clamping piece 28 and the arc-shaped clamping piece 29 connected to the vertical rod 22 maintain a stable working state during the tensile test, avoiding changes in the clamping angle due to accidental rotation, thereby ensuring the stability and consistency of the material stress during the tensile test and improving the accuracy and reliability of the test results.

[0038] Among them, the reset component 41 includes a spring pin, a cylinder and an electric push rod;

[0039] In this example, the reset component 41 is preferably a spring pin, which is convenient to install and has a sensitive response. The spring pin, due to its elasticity, can quickly and securely insert into the socket 42, locking the rotational position of the vertical rod 22. When it is necessary to adjust the position of the vertical rod 22, only a certain external force needs to be applied to disengage the spring pin from the socket 42, making the operation simple and efficient.

[0040] Both of the movable blocks 15 are provided with maintenance components 5 on their exteriors. Each maintenance component 5 includes an observation window 51 and a cover plate 52. The observation window 51 is opened on the outside of the movable block 15, and the cover plate 52 is installed on the inside of the movable block 15.

[0041] The working conditions of the steering assembly 2, guide assembly 3, and locking component 4 inside the moving block 15 can be observed through the observation window 51. When internal inspection or maintenance is required, the cover plate 52 can be opened.

[0042] The bottom of the steering assembly 2 is provided with a pulling component 6, which includes a connecting plate 61. The connecting plate 61 is installed at the bottom of the flat clamping member 28 and the arc-shaped clamping member 29, and a pull handle 62 is fixedly connected to the bottom of the connecting plate 61.

[0043] When a person pulls the handle 62, the flat clamping member 28 and the arc-shaped clamping member 29 on the top of the connecting plate 61 move downwards. The mounting plate 27 then moves the vertical rod 22 downwards. When the insert block 24 on the vertical rod 22 disengages from the slot 23, the direction of the handle 62 is rotated. At this time, the spatial position of the flat clamping member 28 and the arc-shaped clamping member 29 can be changed to meet the requirements of clamping the object.

[0044] The planar clamping member 28 is fixedly connected to a plurality of triangular blocks 7, which are arranged in a linear array and equidistantly distributed on the outside of the planar clamping member 28.

[0045] The triangular block 7 increases the friction between the planar clamping member 28 and the planar material, making the planar material more securely clamped during the tensile test. Furthermore, the triangular block 7 has a layer of rubber material on its exterior to increase friction.

[0046] The arc-shaped clamping member 29 has a plurality of semi-circular toothed plates 8 inside, which are arranged in a linear array inside the arc-shaped clamping member 29 and are rotatably connected.

[0047] The semi-circular toothed plates 8 can be adaptively adjusted according to the surface contour of the circular material to better fit the circular material and enhance the clamping effect. Several semi-circular toothed plates 8 are all connected by a rotating shaft, which is installed inside the arc-shaped clamping member 29. Rubber material is also provided on the outside of several semi-circular toothed plates 8 to increase the friction during clamping.

[0048] The moving block 15 is provided with cleaning components 9 on both the front and back sides. The cleaning component 9 includes a bracket 91, which is installed on the outside of the moving block 15. A brush 92 is provided on the inner side of the bracket 91, and the outside of the brush 92 is slidably connected to the outside of the planar clamping component 28 and the arc-shaped clamping component 29.

[0049] When switching between the flat clamp 28 and the arc-shaped clamp 29 via the vertical rod 22, the brush 92 on the bracket 91 can automatically clean the impurities on the surface of the flat clamp 28 and the arc-shaped clamp 29, keeping the clamps clean.

[0050] The working principle of the tensile testing device for building engineering testing provided by this utility model is as follows:

[0051] First, ensure the device is in its initial ready state. When testing a flat material, the operator pulls handle 62, which moves connecting plate 61 downwards, causing the flat clamp 28, arc-shaped clamp 29, mounting plate 27, and connected vertical rod 22 to move downwards together. During this process, the elastic element 26 sleeved on the outside of vertical rod 22 is compressed, and the insert 24 at the top of vertical rod 22 disengages from the slot 23 at the top of the inner wall of receiving groove 21. Next, rotate handle 62, causing flat clamp 28 and arc-shaped clamp 29 to rotate 180 degrees, completing the positional change. At this time, because the reset element 41 in locking component 4 disengages from the insertion holes 42 around insert 24, vertical rod 22 can rotate freely. Subsequently, release handle 62, releasing the pressure of elastic element 26, pushing vertical rod 22 upwards, causing insert 24 to re-insert into slot 23, completing the position locking of flat clamp 28 and ensuring its stability during testing. Finally, the drive components 14 on the outside of the two sets of receiving boxes 13 are activated. The motors of the drive components 14 drive the bidirectional screws to rotate, causing the moving blocks 15 inside the two sets of receiving boxes 13 to move towards each other, thereby driving the planar clamping member 28 to clamp the planar material. The receiving box 13 fixed at the top of the tensile body 1 and the movable receiving box 13 at the bottom of the telescopic member 12 are respectively fixedly clamped from both ends of the planar material. After the clamping is stable, the telescopic member 12 rises, applying tensile force to the planar material, thereby realizing the tensile test of the planar material.

[0052] Compared with related technologies, the tensile testing device for building engineering testing provided by this utility model has the following beneficial effects:

[0053] By incorporating a steering component 2 within the moving block 15, the need for frequent fixture changes, as is common in traditional methods, is eliminated. Operators simply need to pull the pulling component 6 to move components such as the flat clamping member 28 and the curved clamping member 29, allowing for quick switching of clamping methods based on material shape. For example, when inspecting flat materials, a simple operation positions the flat clamping member 28 in the working position; to inspect materials with curved surfaces, the operation switches to the curved clamping member 29, significantly reducing fixture change time and improving the continuity of the testing process.

[0054] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
