Description

Technical Field

[0001] This utility model relates to the field of materials testing technology, specifically to an adjustable building materials testing chamber. Background Technology

[0002] Against the backdrop of rapid development in the construction industry, building panels, as the basic material for various building structures, have their strength performance directly related to the overall safety and durability of building projects. Therefore, accurate testing of the strength of building panels is a key link in ensuring project quality.

[0003] However, in current strength testing of building panels, traditional fixing methods often rely on two or more bolts. This method is difficult to adapt flexibly to panels of different specifications. For panels with large size differences, it is often necessary to readjust the bolt positions or replace the fixing devices, which is cumbersome and inefficient. At the same time, it is not easy to control the tightness of the bolt fixing. If it is too loose, the panel may shift during the testing process, while if it is too tight, the panel may suffer stress damage in advance, affecting the accuracy of the test results and failing to provide a stable and reliable fixing guarantee for the strength testing of building panels.

[0018] Figures 1-9 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figure 1 -Appendix Figure 9 The present invention will be further described below.

[0019] An adjustable building material testing chamber includes a chamber body 1. A hydraulic cylinder 2 is fixedly installed on the top of the chamber body 1, and a stamping plate is fixedly installed on the output end of the hydraulic cylinder 2. A rectangular detection groove 3 is opened on the bottom surface of the chamber body 1. A rectangular leakage hole 4 is opened on the bottom surface of the rectangular detection groove 3. Two T-shaped slide rails 9 are symmetrically fixedly installed on both sides of the rectangular leakage hole 4. A collection box 5 is movably installed on the bottom of the chamber body 1. A material collection plate 23 is movably installed inside the rectangular detection groove 3. A rectangular movable groove 8 is opened on the bottom surface of the chamber body 1. A motor 6 is fixedly installed on one side of the chamber body 1. A first transmission wheel 7 is set on the other side of the chamber body 1. Four limiting grooves 101 are symmetrically opened on the bottom surface of the chamber body 1. A fixing component for clamping and positioning building materials is set inside the rectangular detection groove 3. A connecting component is set at the bottom of the chamber body 1. The material collection plate 23 is used in conjunction with the connecting component.

[0020] In this implementation scheme, the housing 1 serves as the main structure of the test chamber, providing an installation carrier and storage space for each component, thus forming the overall framework for the testing operation. The hydraulic cylinder 2 is fixedly installed on the top of the housing 1 (existing technology) and controlled by an externally connected intelligent control device. Its output drives the movement of the stamping plate, providing pressure for the strength testing of the building materials. It also works with the intelligent control device to record the critical value at the moment of material fracture. A rectangular testing groove 3 is formed on the bottom surface inside the housing 1, providing a specific area for the placement and testing of the building materials, defining the testing position. A rectangular leakage hole 4 is formed inside the bottom surface of the rectangular detection groove 3, serving as a channel for debris generated during the detection process to fall into the collection box 5. T-shaped slide rails 9 are symmetrically fixed on both sides inside the rectangular leakage hole 4, cooperating with the T-shaped slide groove of the slider 13 to guide and limit the movement of the slider 13, ensuring smooth movement of the slider 13 and the fixed plate 14. The collection box 5 is movably installed at the bottom of the box body 1 to collect the debris falling through the rectangular leakage hole 4, achieving centralized collection of debris for easy subsequent cleaning. The collection plate 23 is movably installed inside the rectangular detection groove 3. Used in conjunction with the connecting assembly, it can move within the rectangular detection groove 3, assisting in guiding debris through the rectangular perforation 4 into the collection box 5. A rectangular movable groove 8 is formed on the bottom surface inside the box 1, providing installation and movement space for the bidirectional screw 10 and the L-shaped connecting rod 11. The motor 6 is fixedly installed on one side of the box 1, providing power for the rotation of the bidirectional screw 10. The first transmission wheel 7 is located on the other side of the box 1 and is fixedly connected to the other end of the bidirectional screw 10. Power from the motor 6 is transmitted to the second transmission wheel 18 via a transmission belt, achieving power linkage between the fixed assembly and the connecting assembly. Four limiting grooves 101 are symmetrically opened on the bottom surface of the box 1. They limit the limiting blocks at the bottom of the connecting rod 12, ensuring the stability of the movement trajectory of the connecting rod 12 and ensuring the normal linkage of the fixing components. The fixing components are set inside the rectangular detection groove 3 and are used to clamp and position the building panels. Through the linkage of various components, the panels of different specifications are firmly clamped, ensuring the stability of the panel position during the detection process. The connecting components are set at the bottom of the box 1 and are used in conjunction with the collecting plate 23 to transmit the power of the motor 6 to the collecting plate 23, driving the collecting plate 23 to move and assisting in the collection of debris.

[0021] Specifically, the fixing component includes a bidirectional screw 10, which is movably installed inside the rectangular movable slot 8. One end of the bidirectional screw 10 is fixedly installed to the output end of the motor 6, and the other end of the bidirectional screw 10 passes through the housing 1 and is fixedly installed to one side of the first transmission wheel 7. Two L-shaped connecting rods 11 are movably installed inside the rectangular movable slot 8. A threaded hole is opened on one side of the L-shaped connecting rod 11, and the threaded hole is threadedly connected to the bidirectional screw 10.

[0022] In this embodiment, a bidirectional screw 10 is movably installed inside a rectangular movable slot 8. One end is fixed to the output end of the motor 6, and the other end passes through the housing 1 and is fixed to one side of the first transmission wheel 7. It rotates under the drive of the motor 6 and moves through the threaded connection with the L-shaped connecting rod 11. The rectangular movable slot 8 provides installation and movement space for the bidirectional screw 10 and the L-shaped connecting rod 11. There are two L-shaped connecting rods 11, which are movably installed inside the rectangular movable slot 8. One side has a threaded hole, which is threaded to the bidirectional screw 10. Under the drive of the bidirectional screw 10, they move relative to each other or in opposite directions along the rectangular movable slot 8 to realize the transmission and conversion of power.

[0023] Specifically, the fixing assembly also includes four connecting rods 12, which are rotatably mounted on the bottom of two L-shaped connecting rods 11. A limiting block is fixedly mounted on the bottom of the connecting rod 12, and the limiting block is movably fitted inside the limiting groove 101. A slider 13 is rotatably mounted on the bottom of the connecting rod 12 near one end. A T-shaped groove is opened on the side of the slider 13 near the T-shaped slide rail 9, and the T-shaped slide rail 9 is movably fitted inside the T-shaped slide groove.

[0024] In this embodiment, four connecting rods 12 are rotatably mounted at the bottom of two L-shaped connecting rods 11, serving to connect the L-shaped connecting rods 11 and the slider 13, transmitting the movement of the L-shaped connecting rods 11 to the slider 13, thus realizing the transfer and transmission of power. A limiting block is fixedly mounted at the bottom of the connecting rod 12 and movably sleeved inside the limiting groove 101, limiting and guiding the movement of the connecting rod 12. The slider 13 is rotatably mounted at the bottom of the connecting rod 12 near one end, with a T-shaped groove on one side. Driven by the connecting rod 12, it moves along the T-shaped slide rail 9, thereby driving the fixed plate 14 to move. The specific movement process is as follows: when the motor 6 drives the bidirectional screw 10 to rotate, the two L-shaped connecting rods 11 move in opposite directions within the rectangular movable groove 8, generating tension in the L-shaped connecting rods 11, pulling the connecting rods 12 rotatably connected to their bottoms, forcing the two bottom connecting rods 12 to move relative to each other and rotate and retract. At this time, the connecting rods 12... The limiting block at the bottom of rod 12 slides along the limiting groove 101 to limit the rotation of connecting rod 12. During the rotation of connecting rod 12, the slider 13, which is rotatably installed near one end of its bottom, moves linearly along the T-shaped slide rail 9 through the cooperation of the T-shaped slide groove and the T-shaped slide rail 9 under the pull of connecting rod 12. This ultimately achieves the relative movement of the slider 13 and the fixing plate 14, completing the clamping action of the building material. When the two L-shaped connecting rods 11 move relative to each other under the drive of the bidirectional screw 10, the L-shaped connecting rods 11 generate thrust, pushing the connecting rod 12, which is rotatably connected to its bottom, forcing the two connecting rods 12 at the bottom to move and rotate. During the rotation of connecting rod 12, the slider 13, which is rotatably installed near one end of its bottom, moves linearly along the T-shaped slide rail 9 through the cooperation of the T-shaped slide groove and the T-shaped slide rail 9 under the push of connecting rod 12. This ultimately achieves the opposite movement of the slider 13 and the fixing plate 14, completing the release action of the building material.

[0025] Specifically, the fixing assembly also includes four fixing plates 14. The fixing plates 14 are fixedly installed on the other side of the slider 13. A rectangular groove 15 is provided at the bottom of the fixing plate 14. An L-shaped support plate 16 is rotatably installed inside the rectangular groove 15. An installation groove is provided on one side of the L-shaped support plate 16. A spring 17 is fixedly installed on one side of the L-shaped support plate 16 by a rectangular block. The other end of the spring 17 is fixedly installed to the bottom surface of the installation groove.

[0026] In this embodiment, a fixing plate 14 is fixedly installed on the other side of the slider 13. It moves towards or away from the slider 13 as the slider 13 moves, directly contacting the building material and clamping it. A rectangular groove 15 is provided at the bottom to provide installation space for the L-shaped support plate 16 and the spring 17. The L-shaped support plate 16 is rotatably installed inside the rectangular groove 15. An installation groove is provided on one side, which can rotate to a vertical state under the pressure of the building material to support the bottom of the material and enhance clamping stability. The spring 17 is fixedly installed by a rectangular block. Under the action of the spring 17, it can return to the initial tilted state. The rectangular block is fixedly installed on one side of the L-shaped support plate 16 to connect the spring 17, so that the spring 17 can act stably on the L-shaped support plate 16.

[0027] Specifically, the connecting assembly includes a second transmission wheel 18, which is rotatably mounted on one side of the housing 1. A transmission belt is movably sleeved on the outer side of the first transmission wheel 7 and the second transmission wheel 18. A movable rod 19 is rotatably mounted on one side of the second transmission wheel 18, and a round hole is opened on one side of the movable rod 19.

[0028] In this embodiment, a second transmission wheel 18 is rotatably mounted on one side of the housing 1, and a transmission belt is fitted on its outer side together with the first transmission wheel 7. It can rotate synchronously under the drive of the first transmission wheel 7, transmitting power to the movable rod 19. The movable rod 19 is rotatably mounted on one side of the second transmission wheel 18 and moves with the rotation of the second transmission wheel 18. A round hole is opened on one side for cooperating with the round rod of the rectangular rod 21 to transmit power to the rectangular rod 21. The round hole is opened on one side of the movable rod 19 to provide space for the round rod of the rectangular rod 21 to move. The diameter of the round hole is larger than the diameter of the round rod so that the movement of the movable rod 19 can drive the rectangular rod 21 to move up and down.

[0029] Specifically, the connecting assembly also includes a U-shaped frame 20, which is fixedly installed at the bottom of the housing 1. A rectangular rod 21 is rotatably installed inside the U-shaped frame 20. A round rod is fixedly installed at one end of the rectangular rod 21 near the movable rod 19, and the round rod is movably sleeved inside the round hole.

[0030] In this embodiment, a U-shaped frame 20 is fixedly installed at the bottom of the housing 1, and a rectangular rod 21 is rotatably installed inside it, providing a stable fulcrum for the rectangular rod 21 to ensure that the rectangular rod 21 can rotate smoothly around it. The rectangular rod 21 is rotatably installed inside the U-shaped frame 20, and a round rod is fixedly installed at one end near the movable rod 19. It can rotate around the U-shaped frame 20 under the drive of the movable rod 19, transmitting power to the top rod 22. The round rod is fixedly installed at one end of the rectangular rod 21 near the movable rod 19 and is movably sleeved inside the round hole of the movable rod 19, so that the rectangular rod 21 can rotate with the movement of the movable rod 19. The length design of the round rod can prevent it from falling out of the round hole, realizing the transmission of power from the movable rod 19 to the rectangular rod 21.

[0031] Specifically, the connecting assembly also includes a top rod 22, which is rotatably mounted on the other end of the rectangular rod 21. The top rod 22 passes through the bottom of the box 1, and the top of the top rod 22 is fixedly installed with the bottom of the collecting plate 23.

[0032] In this embodiment, a top rod 22 is rotatably mounted on the other end of a rectangular rod 21, penetrating the bottom of the housing 1, and its top end is fixedly mounted to the bottom of the collecting plate 23. This converts the rotation of the rectangular rod 21 into its own up-and-down movement, thereby driving the collecting plate 23 to move synchronously. The rectangular rod 21 drives the top rod 22 to move up and down through its own rotation. The bottom of the collecting plate 23 is fixedly mounted to the top end of the top rod 22, and under the drive of the top rod 22, it achieves up-and-down movement, thus assisting in the collection of debris.

[0033] Specifically, the aggregate plate 23 is set at an angle, the two fixing plates 14 are set opposite to each other, and a number of anti-slip protrusions are fixedly installed on one side of the fixing plate 14. The L-shaped support plate 16 is initially set at an angle.

[0034] In this embodiment, the material collection plate 23 is set at an angle to guide the debris generated during the up-and-down movement, causing the debris to slide down the angle to the rectangular drain hole 4, thereby improving the debris collection efficiency. The anti-slip protrusion is fixedly installed on one side of the fixing plate 14, which increases the contact friction with the building material and further improves the clamping stability of the fixing plate 14 on the material, ensuring the stability of the material position during the test. The L-shaped support plate 16 is initially set at an angle. When the building material is placed, it will rotate to a vertical state under the pressure of the material to support the bottom of the material, enhancing the overall stability of the material clamping. After the test is completed, it will return to the initial angled state under the action of the spring 17.

[0035] In summary: When using this utility model, before the test, the building material to be tested is manually placed in the rectangular testing groove 3. After the motor 6 is connected to the external power supply and started, the motor 6 drives the bidirectional screw 10 to rotate in the rectangular movable groove 8. Since the two L-shaped connecting rods 11 are threadedly connected to the bidirectional screw 10 through threaded holes, the L-shaped connecting rods 11 move in opposite directions in the rectangular movable groove 8. The resulting tension pulls the four connecting rods 12 that are rotatably connected to their bottoms, forcing the two bottom connecting rods 12 to move relative to each other and rotate and retract. The limiting block at the bottom of the connecting rod 12 slides along the limiting groove 101 to limit the movement. When the connecting rod 12 retracts, it pulls the slider 13. The slider 13 moves linearly along the T-shaped slide rail 9 through the cooperation of the T-shaped slide groove and the T-shaped slide rail 9, thereby driving the fixed plate 14 to move relative to it. The anti-slip protrusion on one side of the fixed plate 14 increases the friction with the plate. The plate squeezes the L-shaped support plate 16, causing it to rotate from the initial tilted state to a vertical state to support the bottom of the plate. The spring 17 is stretched, completing the clamping and fixing of the plate. During testing, the hydraulic cylinder 2 is started through the external intelligent control device, driving the stamping plate to move downward to apply pressure to the plate. The intelligent control device records the critical moment when the plate breaks. The material fragments from the broken plate fall onto the collecting plate 23. After the test, the motor 6 reverses and drives the bidirectional screw 10 to rotate in the opposite direction. The L-shaped connecting rod 11 moves relative to the plate and pushes the connecting rod 12 to move and rotate. The connecting rod 12 drives the slider 13 and the fixed plate 14 to move in opposite directions, releasing the plate. The remaining plate is then manually removed. The L-shaped support plate 16 returns to its initial tilted state under the action of the spring 17. When the bidirectional screw 10 rotates, it drives the first transmission wheel 7 to rotate. The first transmission wheel 7 drives the second transmission wheel 18 to rotate through the transmission belt. The second transmission wheel 18 drives the movable rod 19. Rotating, the movable rod 19 engages with the round rod at one end of the rectangular rod 21 through the round hole, causing the rectangular rod 21 to rotate around the U-shaped frame 20. The top rod 22 at the other end of the rectangular rod 21 moves up and down accordingly, thereby causing the collecting plate 23 to move up and down within the rectangular detection groove 3. Its inclined surface design, combined with the movement, guides the debris to the rectangular drain hole 4. The debris falls into the collection box 5 through the rectangular drain hole 4. During the adjustment of the fixed component, the connecting component will move synchronously. Since the collecting plate 23 is a certain distance away from the fixed component, when the collecting plate 23 is driven up and down by the connecting component, it will not hinder the operation of the fixed component.

[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
