Technical Field
[0001] This utility model relates to the field of material strength testing technology, and more specifically, to a convenient material strength testing device. Background Technology
[0002] In construction engineering, the strength of building materials is directly related to the quality and safety of the project. Therefore, it is necessary to test the strength of building materials. There are many types of building materials, including structural materials, decorative materials and certain special materials. The strength performance of different materials is crucial to the stability and durability of the building.
[0003] A search revealed Chinese patent application CN202120847628.0, which discloses a building material strength testing device. The device includes a base frame with an internal groove containing a first threaded rod and a first smooth rod. A slider is threaded onto the outer surface of the first threaded rod. A movable clamp is fixedly connected to the upper surface of the slider, comprising a fixed sleeve, a lead screw, a rotating handle, and an abutment block. A support frame is fixedly connected to the upper surface of the base frame, and a fixed clamp is fixedly connected to the upper surface of the support frame. The fixed clamp and the movable clamp have identical structures. A tensile testing instrument is fixedly connected to the inner wall of the base frame, with a tension spring fixedly connected to one end of the instrument and a retaining sleeve fixedly connected to the other end. A bracket is fixedly connected to the upper surface of the base frame, and a bending strength testing device is located at the bottom of the bracket. This device comprises a second threaded rod, a second smooth rod, a movable block, a hydraulic cylinder, and a pressure block. A movable wheel is fixedly connected to the bottom of the base frame.
[0004] While the aforementioned patent utilizes a movable wheel and a first and second threaded rod, allowing the device to be moved to a designated position via the movable wheel, and then the first threaded rod drives the slider, and the second threaded rod drives the movable block to adjust for different lengths of building materials, thus achieving ease of movement and reduced device size, and achieving the goal of convenient use, the use of a clamping sleeve, a movable clamp, and a fixed clamp allows for easy installation and good fixation. During use, the movable clamp can be moved to one side first, then the building material placed inside the fixed clamp, then the end of the building material inserted into the clamping sleeve, and then the movable clamp moved to the other end of the building material, and fixed by rotating the handle and screw. However, the following shortcomings still exist: 1. The center position differs after fixing materials of different sizes, resulting in inconsistent and unstable test data, affecting the test results; 2. The installation and removal of building materials require separate clamping adjustments, which is time-consuming and labor-intensive, affecting testing efficiency. Therefore, a more user-friendly material strength testing device is proposed. Utility Model Content
[0005] The purpose of this invention is to address the problems that currently exist, such as different center positions of materials of different sizes after fixing, resulting in inconsistent and unstable test data, which affects the test data; and that the installation and disassembly of building materials require separate adjustment of clamps, which is time-consuming and labor-intensive, affecting the efficiency of testing.
[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution:
[0007] The present invention is as follows: a convenient material strength testing device, comprising a base frame, a slider slidably connected to the outer wall of the base frame, symmetrically distributed support columns fixedly connected to both the outer wall of the base frame and the top wall of the slider, and a bracket fixedly connected to the top wall of the base frame, and further comprising:
[0008] A fixed disk is fixedly connected to the outer wall of the support column, and a central disk is fixedly connected to the outer wall of the fixed disk;
[0009] The drive assembly includes an electric push rod B rotatably connected to the outer wall of the base frame. The output end of the electric push rod B is rotatably connected to a linkage block. The outer wall of the linkage block is fixedly connected to symmetrically distributed linkage rods.

[0010] The driven clamping component is disposed on the outer wall of the fixed disk, and the driving component and the driven clamping component cooperate with each other.
[0011] As a preferred technical solution of this application, the driven clamping assembly includes guide grooves uniformly opened on the outer wall of the fixed disk, a guide block slidably connected to the inner wall of the guide groove, and the guide block slidably connected to the central disk, a clamping plate fixedly connected to the outer wall of the guide block, an extrusion rod fixedly connected to the outer wall of the guide block, and the extrusion rod is located on the inner wall of the extrusion groove, a limit plate fixedly connected to the outer wall of the extrusion rod, and a material body is uniformly arranged between the clamping plates.
[0012] As a preferred technical solution of this application, a drive motor A is fixedly connected to the outer wall of the base frame, and an adjusting screw A is fixedly connected to the output end of the drive motor A. The adjusting screw A is rotatably connected to the base frame, and the outer wall of the adjusting screw A is threadedly connected to the slider.
[0013] As a preferred technical solution of this application, the outer wall of the base frame is fixedly connected with symmetrically distributed casters.
[0014] As a preferred technical solution of this application, an adjusting screw B is rotatably connected to the outer wall of the bracket, a moving block is threadedly connected to the outer wall of the adjusting screw B, and the moving block is slidably connected to the bracket.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0018] 1. By setting the driven clamping component to cooperate with the driving component, the clamping plate clamps the material from multiple directions toward the center, ensuring that materials of different diameters or heights are all centrally positioned, avoiding deviations in test data caused by non-central clamping, and improving the accuracy of test results. At the same time, multiple sets of clamping plates clamp the material synchronously, changing the shortcomings of the original patent's one-sided clamping of the abutment block, forming a multi-point stable clamping structure, preventing the material from loosening or shifting during the test, ensuring the stability of the test process, and solving the problem in the prior art that different sizes of materials have different central positions after being fixed, resulting in differences in test data and instability, which affects the test data;
[0019] 2. By using linkage rods, linkage blocks, and other structures, synchronous adjustment and locking of the clamping ends can be achieved, eliminating the need to adjust both ends of the material separately. This reduces operation steps, improves testing efficiency, and reduces the workload of operators. It solves the problem in existing technologies where the installation and disassembly of building materials require separate clamping adjustments, which is time-consuming, labor-intensive, and affects testing efficiency.

[0033] like Figure 1-7As shown, this embodiment proposes a convenient material strength testing device, including a base frame 1, a slider 5 slidably connected to the outer wall of the base frame 1, symmetrically distributed support columns 6 fixedly connected to both the outer wall of the base frame 1 and the top wall of the slider 5, and a bracket 26 fixedly connected to the top wall of the base frame 1. It also includes:
[0034] A fixed disk 7 is fixedly connected to the outer wall of the support column 6, and a central disk 11 is fixedly connected to the outer wall of the fixed disk 7.
[0035] The drive assembly includes an electric push rod B28 rotatably connected to the outer wall of the base frame 1. The output end of the electric push rod B28 is rotatably connected to a linkage block 29. The outer wall of the linkage block 29 is fixedly connected to symmetrically distributed linkage rods 30. The outer wall of the linkage rods 30 is slidably connected to a rotating disk 12, and the rotating disk 12 is rotatably connected to the central disk 11.

The linkage rods 30 push the rotating disk 12 to rotate around the central disk 11. When the rotating disk 12 rotates, the extrusion groove 13 rotates with the rotating disk 12.
[0036] The driven clamping component is disposed on the outer wall of the fixed disk 7, and the driving component and the driven clamping component cooperate with each other.

The tension detector 27 is fixedly connected to the base frame 1. When the material body 21 is placed between two sets of fixed plates 7, with the two ends of the material corresponding to the positions of the clamping plates 10, the pin hole 24 of the material body 21 is aligned with the sleeve 22, the pin plate 23 is inserted into the pin hole 24 to complete the initial positioning, and the tension detector 27 is connected to the sleeve 22 through the tension spring 25. When the material is stretched, the tension spring 25 deforms, and the tension detector 27 displays the tension data in real time.

Figure 3 At this point, the pin hole 24 of the material body 21 is aligned with the sleeve 22, and the pin plate 23 is inserted into the pin hole 24 to complete the initial positioning; the electric push rod B28 is activated, and its output end pushes the linkage block 29 to move. The linkage block 29 drives the symmetrical linkage rods 30 to move synchronously, such as... Figure 4The linkage rod 30 pushes the rotating disk 12 to rotate around the central disk 11. When the rotating disk 12 rotates, the extrusion groove 13 follows the rotating disk 12, thereby extruding and pushing the extrusion rod 14 to drive the guide block 9 and the clamping plate 10 to slide along the guide groove 8, that is, the clamping plate 10 moves towards the center position of the material body 21, realizing the central clamping of the material by multiple sets of clamping plates 10; the tensile tester 27 is connected to the ferrule 22 through the tensile spring 25. When the material is under tension, the tensile spring 25 deforms, and the tensile tester 27 displays the tensile data in real time; the drive motor B16 is started, driving the adjusting screw B18 to rotate, and the moving block 17 slides along the bracket 26 to the designated position. The electric push rod A19 is started, pushing the pressure block 20 to press the material body 21 downward. The pressure gauge is set as needed to detect the bending strength data; when the overall position needs to be adjusted, the drive motor A3 drives the adjusting screw A4 to rotate, and the slider 5 slides along the base frame 1 to realize the lateral position adjustment of the device.
