[0001] This utility model belongs to the field of tensile testing technology, specifically, it relates to a tensile testing device for building materials. Background Technology

[0002] In the process of building material production and quality testing, tensile properties are one of the important indicators for evaluating the quality of building materials such as concrete.

[0003] Currently, existing tensile testing devices for building materials have many problems during use. Among them, there is a lack of effective protective measures during testing. During the tensile fracture process of concrete test blocks, the fragments generated are prone to splashing, posing a safety hazard and potentially causing injury to operators. Furthermore, after the test is completed, the fragments will splash to various locations, making cleaning inconvenient and increasing maintenance costs and downtime.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows: A tensile testing device for building materials includes a tensile testing instrument.

[0006] The testing area of ​​the tensile testing instrument is equipped with a protective cover for splash protection; The top of the protective cover is rotatably mounted with a cover plate for opening and closing, and the bottom of the protective cover is rotatably mounted with a discharge plate for discharging broken materials. A synchronization component for synchronous movement is installed between the cover plate and the discharge plate. The synchronization component includes a horizontally sliding synchronization rod, a turntable is installed at the rotation center of the cover plate and a cam groove is opened on the surface of the turntable, a rocker arm is installed at the rotation center of the feed plate and the rocker arm is in an inclined state, one end of the synchronization rod is slidably connected to the cam groove and the other end of the synchronization rod is slidably connected to the rocker arm.

[0007] In a preferred embodiment of this utility model, the tensile testing instrument is equipped with four support legs at its bottom, and the bottom of the four support legs is screwed with an adjustment plate for adjusting the height, and a crossbeam is installed on the adjacent support legs.

[0008] In a preferred embodiment of this utility model, an observation window is installed on the cover plate, and an acrylic plate is embedded in the observation window. A handle is also installed on the cover plate, and an anti-slip sleeve is installed on the handle. A positioning platform for supporting the cover plate after it is flipped is installed on the back of the protective cover, and the positioning platform is triangular.

[0009] In a preferred embodiment of the present invention, a first slide rod is installed at one end of the synchronizing rod, and the first slide rod is slidably disposed on the cam groove.

[0010] In a preferred embodiment of this utility model, a second sliding rod is installed at the other end of the synchronizing rod, and a strip groove is formed on the surface of the rocker arm, in which the second sliding rod is slidably disposed.

[0011] In a preferred embodiment of this utility model, a slide is installed on the side wall of the synchronizing rod, and a limiting rod is movably disposed through the slide.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0017] like Figures 1 to 5 As shown, a tensile testing device for building materials includes a tensile testing instrument 1.

[0018] The testing area of ​​the tensile testing instrument 1 is equipped with a protective cover 5 for splash prevention. The protective cover 5 is made of high-strength, impact-resistant material, which can not only effectively block the splashing of debris when the building material is tensilely broken, reducing the risk of accidental injury to the operator, but also prevent debris from scattering everywhere, reducing subsequent cleaning work and maintaining a clean and orderly working environment.

[0019] The top of the protective cover 5 is rotatably mounted with a cover plate 6 for opening and closing, and the bottom of the protective cover 5 is rotatably mounted with a discharge plate 14 for discharging debris. A synchronization component for synchronous movement is installed between the cover plate 6 and the discharge plate 14. The synchronous opening and closing of the cover plate 6 and the discharge plate 14 is achieved through the synchronization component, which greatly improves the convenience of operation and avoids the cumbersome process of operating the cover plate and the discharge plate separately, enabling operators to perform pre-test preparation and post-test cleaning work more efficiently.

[0020] The synchronization assembly includes a horizontally sliding synchronization rod 13, a turntable 10 mounted at the rotation center of the cover plate 6, and a cam groove 11 opened on the surface of the turntable 10. A rocker arm 15 is mounted at the rotation center of the feed plate 14. The rocker arm 15 is in an inclined state. One end of the synchronization rod 13 is slidably connected to the cam groove 11, and the other end of the synchronization rod 13 is slidably connected to the rocker arm 15.

[0021] like Figures 1 to 5As shown in the specific embodiment, the tensile testing instrument 1 has four support legs 2 installed at its bottom. Adjustment plates 3 for height adjustment are screwed onto the bottom of the four support legs 2, and crossbeams 4 are installed on adjacent support legs 2. The adjustment plates 3 allow for flexible adjustment of the levelness of the tensile testing instrument 1 according to different ground conditions. Whether on a flat surface or a slightly undulating work area, this ensures the testing device remains horizontally stable, thereby guaranteeing the accuracy and reliability of the test results. The crossbeams 4 enhance the connection stability between the support legs 2, improve the structural strength of the entire device, and enable it to remain stable even when subjected to the enormous force during the tensile process of building materials, reducing testing errors caused by device swaying.

[0022] like Figures 1 to 5 As shown, furthermore, an observation window 7 is installed on the cover plate 6, and an acrylic plate is embedded in the observation window 7. A handle 8 is also installed on the cover plate 6, and an anti-slip sleeve is installed on the handle 8. A positioning platform 9 for supporting the flipped cover plate 6 is installed on the back of the protective cover 5, and the positioning platform 9 is triangular. The acrylic plate embedded in the observation window 7 has good light transmission and wear resistance, which allows the operator to clearly observe the tensile state of the building materials during the inspection process, and effectively prevents scratches from affecting the view. The acrylic plate is also lightweight, reducing the overall weight of the cover plate 6. The anti-slip sleeve on the handle 8 has an anti-slip texture design, which increases the friction between the hand and the handle. Even if the operator's hands are oily or sweaty, they can easily and steadily operate the cover plate 6. The positioning platform 9 is triangular, which uses the stability principle of triangles to provide reliable support for the flipped cover plate 6, preventing the cover plate from accidentally slipping and ensuring the safety of the operator. It also prevents the cover plate from colliding with the ground and causing damage.

[0023] like Figures 1 to 5 As shown, a first slide rod 12 is further installed at one end of the synchronizing rod 13, and the first slide rod 12 is slidably mounted on the cam groove 11. The cooperation between the first slide rod 12 and the cam groove 11 makes the movement trajectory of the synchronizing rod 13 more precise during the sliding process, effectively reducing friction and wear during the movement process, extending the service life of the synchronizing assembly, and also ensuring the accuracy and consistency of the synchronous movement of the cover plate 6 and the feed plate 14.

[0024] like Figures 1 to 5 As shown, a second slide rod 17 is further installed at the other end of the synchronizing rod 13, and a strip groove 16 is formed on the surface of the rocker arm 15. The second slide rod 17 is slidably disposed in the strip groove 16. The structural design of the second slide rod 17 and the strip groove 16 enables the rocker arm 15 to smoothly transmit power during rotation, accurately converting the horizontal movement of the synchronizing rod 13 into the flipping movement of the feed plate 14, further ensuring the stable operation of the synchronizing assembly and improving the overall reliability of the device.

[0025] like Figures 1 to 5As shown, a slide block 18 is further installed on the side wall of the synchronizing rod 13. A limiting rod 19 is movably connected through the slide block 18. A limiting seat 21 is installed at one end of the limiting rod 19, and the limiting seat 21 is installed on the side wall of the protective cover 5. A limiting plate 20 is installed at the end of the limiting rod 19. The diameter of the limiting plate 20 is larger than the diameter of the limiting rod 19. A limiting spring 22 is sleeved on the limiting rod 19. One end of the limiting spring 22 is engaged with the side wall of the limiting seat 21, and the other end of the limiting spring 22 is engaged with the side wall of the slide block 18. The limiting structure composed of the limiting rod 19 and the limiting spring 22 can effectively limit the sliding of the synchronizing rod 13 and facilitates subsequent reset by the limiting spring 22.

[0026] The operating principle of a building material tensile testing device is as follows: When testing concrete test blocks, the tensile testing instrument 1 is first brought to a horizontal and stable state by adjusting the adjusting plate 3 at the bottom of the support leg 2, ensuring the accuracy of the test results. The crossbeam 4 is used to enhance the connection stability between the support legs 2, further ensuring the overall stability of the device. When the testing device is opened, the operator holds the handle 8 on the cover plate 6 and pulls the cover plate 6 upward to flip it over. Due to the presence of the synchronization component, the first slide rod 12 at one end of the synchronization rod 13 slides in the cam groove 11 of the turntable 10, pushing the synchronization rod 13 to slide horizontally. The second slide rod 17 at the other end of the synchronization rod 13 slides in the strip groove 16 of the rocker arm 15, causing the rocker arm 15 to rotate, thereby causing the material feeding plate 14 to flip downward and open synchronously. At this time, the internal space of the protective cover 5 is exposed, and the concrete test block is placed in the testing area of ​​the tensile testing instrument 1.

[0027] When the testing device is closed, the cover plate 6 is lowered, and the synchronization component functions again, causing the material feeding plate 14 to flip upwards and close synchronously, forming a closed testing space. After the cover plate 6 is flipped into place, it can be placed on the positioning platform 9 on the back of the protective cover 5 for stable support. The operator can observe the tensile state of the concrete test block in real time during the testing process through the acrylic plate embedded in the observation window 7 on the cover plate 6. When the tensile testing instrument 1 starts working and applies tension to the concrete specimen, the protective cover 5 can effectively prevent the fragments generated during the tensile fracture process from splashing, ensuring the safety of the operators and the cleanliness of the working environment. If fragments are generated during the tensile process, after the test is completed, the cover plate 6 is opened again, and the discharge plate 14 opens simultaneously, allowing the fragments to be discharged through the opening of the discharge plate 14.
