Abstract
Description
Technical Field
[0001] This application relates to the field of building engineering testing technology, and in particular to a clamp for an extensometer used in a tensile testing machine for waterproof materials. Background Technology
[0002] Waterproofing in building materials relies on blocking the pathways of water to achieve waterproofing or increase resistance to leakage. Examples include waterproof membranes, coatings, rigid waterproofing using concrete and cement mortar, and waterproofing with clay and lime-soil mixtures. Commonly used waterproofing materials include waterproof membranes, geotextiles, waterproof boards, and waterproof coatings. Among the properties of waterproofing materials, tensile strength is the most important and a key indicator of its quality.
[0003] When testing waterproof materials, the material is constrained by a tensile testing machine, and then subjected to a tensile test using the same machine. The tensile properties of the material are then measured using an extensometer, which facilitates the evaluation of the waterproof material's performance.
[0004] When using extensometer clamps to test the tensile properties of waterproof materials, the extensometer is fixed to the material by the clamps when the waterproof material is being stretched by a tensile testing machine. As the material is stretched, the extensometer moves, facilitating the testing of tensile properties. However, in some existing devices, the extensometer and clamps are usually fixedly connected by bolts or connecting plates, making the distance between the extensometer and clamps constant. This makes it difficult to adjust and to test the horizontal state of the clamps. Furthermore, when the two clamps move on the extensometer, they are only restricted by the extensometer, without other restrictions, which makes it difficult to move the clamps stably and can easily affect the accuracy of the extensometer measurement. Utility Model Content
[0005] The purpose of this application is to address the problems that extensometers and clamps are generally fixedly connected by bolts or connecting plates, resulting in a fixed distance between the extensometer and clamps, which is inconvenient for adjustment and for detecting the horizontal state of the clamps. Furthermore, when the two clamps move on the extensometer, they are only restricted by the extensometer and there are no other restrictions, which makes it difficult for the clamps to move stably and thus easily affects the accurate measurement of the extensometer. This application provides a clamp for the extensometer of a tensile testing machine for waterproof materials.
[0006] To achieve the above objectives, this application specifically adopts the following technical solution:
[0007] A fixture for an extensometer used in a tensile testing machine for waterproof materials includes a frame, a limiting frame at the lower end of the frame, a fixing plate at one end of both the limiting frame and the frame, an extensometer body at the end of the fixing plate away from the frame, the fixing plate and the extensometer body being slidably disposed, an adjusting column at one end of both the frame and the limiting frame, an adjusting plate on each of the two adjusting columns, and an adjusting mechanism between the frame and the extensometer body.
[0008] By adopting the above technical solution and adjusting the mechanism, the position of the clamp can be adjusted so that the clamp corresponds to the waterproof material, which facilitates stable clamping and adjustment of the clamp, allows the staff to monitor the horizontal status of the clamp in real time, facilitates the stable movement of the clamp on the extensometer, and facilitates the accurate measurement of the extensometer.
[0009] Furthermore, the adjustment mechanism includes a sliding column fixed in the fixed plate. The fixed plate is slidably disposed with the frame and the limiting frame. One end of the frame and the limiting frame extends into the fixed plate and is slidably disposed with the sliding column. An abutting column is threadedly connected to the fixed plate. The abutting column abuts against the frame and the limiting frame. A limiting component is disposed between the fixed plate and the extensometer.
[0010] By adopting the above technical solution, the abutment column on the fixed plate is turned to move the abutment column, thereby releasing the restriction on the frame and the restraint frame, allowing the frame and the restraint frame to slide on the sliding column, which facilitates the restriction of the frame and the adjustment of the position of the clamp.
[0011] Furthermore, the limiting component includes a limiting post slidably disposed on the fixed plate, the limiting post penetrating the fixed plate, a limiting block fixed at both ends of the limiting post, reinforcing strips fixed on the fixed plate and distributed in an array, and horizontal bubbles fixed on the side of the fixed plate.
[0012] By adopting the above technical solution, when the fixture moves, the fixed plate slides on the limiting post, which facilitates the restriction of the fixed plate. The limiting block restricts the limiting post, which facilitates the stable movement of the fixture. The horizontal bubble facilitates the detection of the horizontal state of the fixture during testing, which facilitates the accurate measurement of the extensometer. The reinforcing strip increases the stability of the fixture.
[0013] Furthermore, the adjusting column and the adjusting plate are slidably arranged, and the adjusting column and the adjusting plate are fixed by bolts.
[0014] By adopting the above technical solution, the bolts on the adjusting plate can be turned off to release the restriction on the adjusting plate, allowing the adjusting plate to slide on the adjusting column and be fixed in a suitable position, so as to facilitate the adjustment of the position of the adjusting plate according to the size of the material.
[0015] Furthermore, the limiting frame, the frame body, and the adjusting plate are all slidably provided with two symmetrical fixed columns. The adjusting plate corresponds to the limiting frame and the frame body respectively. The fixed columns pass through the limiting frame, the frame body, and the adjusting plate and are fixedly connected to the limiting plate.
[0016] By adopting the above technical solution, pulling the connecting plate causes the fixed column to move, which in turn moves the limiting plate, making it easier to restrict the material.
[0017] Furthermore, the end of the fixed column away from the limiting plate is fixedly connected to the connecting plate, a spring is sleeved on the fixed column, the spring is fixedly connected to the connecting plate, and the end of the spring away from the connecting plate is fixedly connected to the frame, the limiting frame, and the adjusting plate.
[0018] By adopting the above technical solution, when the spring extends and retracts, and the limiting plate corresponds to the waterproof material, the elasticity of the spring drives the limiting plate to move, which facilitates the restriction of the material.
[0019] Furthermore, a rotating column is threadedly connected to the connecting plate, and a fixing block is fixed to one end of the rotating column. The fixing block is used for contact with the connecting plate, and the rotating column is rotatably connected to the adjusting plate, the frame, and the limiting frame.
[0020] By adopting the above technical solution, the fixing block is turned, causing the fixing column to rotate, the connecting plate to move, and the spring to extend and retract. This makes it easy to adjust the spring force, increase the resistance of the limiting plate, and facilitate clamping.
[0021] Furthermore, a pad is fixed to one side of the limiting plate, and the pad is a flexible rubber pad.
[0022] By adopting the above technical solution, the pad is made of rubber, which facilitates the restriction and protection of the material.
[0023] In summary, this application includes at least one of the following beneficial effects:
[0024] 1. When using the extensometer clamp, screwing on the abutment post on the fixed plate moves the abutment post, releasing the restriction on the frame and the limiting frame. This allows the frame and the limiting frame to slide on the sliding post, facilitating the restriction of the frame, adjusting the position of the clamp, and ensuring accurate alignment with the waterproof material. As the clamp moves, the fixed plate slides on the limiting post, facilitating the restriction of the fixed plate. The limiting block restricts the limiting post, ensuring stable movement of the clamp. The level bubble helps detect the horizontal state of the clamp during testing, facilitating accurate measurement by the extensometer. The reinforcing strip increases the stability of the clamp. The adjustment mechanism allows for easy adjustment of the clamp's position, ensuring alignment with the waterproof material, facilitating stable clamping and adjustment, allowing workers to monitor the horizontal state of the clamp in real time, facilitating stable movement of the clamp on the extensometer, and ensuring accurate measurement by the extensometer.
[0025] 2. When using the extensometer clamp, the bolts on the adjusting plate can be loosened to release the restriction on the adjusting plate, allowing it to slide on the adjusting column and be fixed in a suitable position. This facilitates adjusting the position of the adjusting plate according to the material size and the spacing of the clamps. Pulling the connecting plate moves the fixed column, causing the spring to extend and retract. When the limiting plate aligns with the waterproof material, the elasticity of the spring drives the limiting plate to move, facilitating the restriction of the material. The pad is made of rubber, which facilitates the restriction and protection of the material and allows for clamping according to the material width. Tightening the fixing block rotates the fixed column, causing the connecting plate to move and the spring to extend and retract, facilitating the adjustment of the spring force and increasing the resistance of the limiting plate for easier clamping.

[0032] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0033] This application discloses a fixture for the extensometer of a tensile testing machine used for waterproof materials.
[0034] Reference Figure 1 and Figure 2A fixture for an extensometer used in a tensile testing machine for waterproof materials includes a frame 1, a limiting frame 4 at the lower end of the frame 1, a fixing plate 2 at one end of both the limiting frame 4 and the frame 1, an extensometer body 3 at the end of the fixing plate 2 away from the frame 1, the fixing plate 2 and the extensometer body 3 being slidably disposed, an adjusting column 11 at one end of both the frame 1 and the limiting frame 4, an adjusting plate 5 on each of the two adjusting columns 11, and an adjusting mechanism between the frame 1 and the extensometer body 3.
[0035] When using the extensometer clamp, the extensometer body 3 is fixed to the tensile testing machine. The position of the clamp is adjusted by the limiting frame 4 and the adjusting column 11, which are in conjunction with the adjusting mechanism. This makes it easy to adjust the position of the clamp so that the clamp corresponds to the waterproof material, which facilitates the stable clamping and adjustment of the clamp, allows the staff to monitor the horizontal state of the clamp in real time, facilitates the stable movement of the clamp on the extensometer, and facilitates the accurate measurement of the extensometer.
[0036] Reference Figure 2 and Figure 3 The adjusting mechanism includes a sliding column 9 fixed within a fixed plate 2. The fixed plate 2 is slidably configured with respect to the frame 1 and the limiting frame 4. One end of the frame 1 and the limiting frame 4 extends into the fixed plate 2 and is slidably configured with respect to the sliding column 9. A contact column 8 is threadedly connected to the fixed plate 2, and the contact column 8 abuts against the frame 1 and the limiting frame 4. A limiting assembly is provided between the fixed plate 2 and the extensometer. The limiting assembly includes a limiting column 7 slidably configured on the fixed plate 2, which penetrates the fixed plate 2. Limiting blocks 10 are fixed at both ends of the limiting column 7. Reinforcing strips 6 are fixed on the fixed plate 2 and arranged in an array. Horizontal bubbles 16 are fixed to the side of the fixed plate 2.
[0037] When using the extensometer clamp, the contact post 8 on the fixed plate 2 is turned to move the contact post 8, releasing the restriction on the frame 1 and the limiting frame 4, allowing the frame 1 and the limiting frame 4 to slide on the sliding post 9. This facilitates the restriction of the frame 1, the adjustment of the clamp's position, and the accurate alignment with the waterproof material. When the clamp moves, the fixed plate 2 slides on the limiting post 7, facilitating the restriction of the fixed plate 2. The limiting block 10 restricts the limiting post 7, facilitating the stable movement of the clamp. The level bubble 16 facilitates the detection of the clamp's horizontal state during testing, ensuring accurate measurement by the extensometer. The reinforcing strip 6 increases the stability of the clamp. The adjustment mechanism allows for the adjustment of the clamp's position, aligning the clamp with the waterproof material, facilitating stable clamping and adjustment, enabling staff to monitor the clamp's horizontal state in real time, ensuring stable movement of the clamp on the extensometer, and facilitating accurate measurement by the extensometer.
[0038] Reference Figure 3 and Figure 4The adjusting column 11 and the adjusting plate 5 are slidably connected and fixed to each other by bolts. Two symmetrical fixing columns 12 are slidably connected to the limiting frame 4, the frame body 1, and the adjusting plate 5. The adjusting plate 5 corresponds to the limiting frame 4 and the frame body 1, respectively. The fixing columns 12 pass through the limiting frame 4, the frame body 1, and the adjusting plate 5 and are fixedly connected to the limiting plate 18. The end of the fixing column 12 away from the limiting plate 18 is fixedly connected to the connecting plate 14. A spring 13 is sleeved on the fixing column 12 and fixedly connected to the connecting plate 14. The end of the spring 13 away from the connecting plate 14 is fixedly connected to the frame body 1, the limiting frame 4, and the adjusting plate 5. A rotating column 15 is threadedly connected to the connecting plate 14. A fixing block 17 is fixed to one end of the rotating column 15. The fixing block 17 is used for contact with the connecting plate 14. The rotating column 15 is rotatably connected to the adjusting plate 5, the frame body 1, and the limiting frame 4. A pad 19, which is a flexible rubber pad, is fixed to one side of the limiting plate 18.
[0039] When using the extensometer clamp, the bolts on the adjusting plate 5 can be loosened to release the restriction on the adjusting plate 5, allowing the adjusting plate 5 to slide on the adjusting column 11 and be fixed in a suitable position. This facilitates adjusting the position of the adjusting plate 5 according to the material size and the spacing of the clamp. Pulling the connecting plate 14 moves the fixing column 12, causing the spring 13 to extend and retract. When the limiting plate 18 corresponds to the waterproof material, the elasticity of the spring 13 drives the limiting plate 18 to move, facilitating the restriction of the material. The pad 19 is made of rubber, which facilitates the restriction and protection of the material and allows for clamping according to the width of the material. The fixing block 17 can be loosened to rotate the fixing column 12, causing the connecting plate 14 to move and the spring 13 to extend and retract. This allows for adjusting the elasticity of the spring 13, increasing the resistance of the limiting plate 18, and facilitating clamping.
[0040] The implementation principle of the clamp for the extensometer of a tensile testing machine for waterproof materials in this embodiment is as follows: When the clamp for the extensometer is in use, the extensometer body 3 is fixed to the tensile testing machine. When the clamp for the extensometer is in use, the abutment post 8 on the fixing plate 2 is turned to move the abutment post 8, thereby releasing the restriction on the frame 1 and the limiting frame 4, allowing the frame 1 and the limiting frame 4 to slide on the sliding post 9. This facilitates the restriction of the frame 1, the adjustment of the clamp position, and the accurate correspondence with the waterproof material.
[0041] When the fixture moves, the fixed plate 2 slides on the limiting post 7, which facilitates the restriction of the fixed plate 2. The limiting post 7 is restricted by the limiting block 10, which facilitates the stable movement of the fixture. The horizontal bubble 16 facilitates the detection of the horizontal state of the fixture during testing, which facilitates the accurate measurement of the extensometer. The reinforcing strip 6 increases the stability of the fixture.
[0042] When using the extensometer clamp, the bolts on the adjusting plate 5 can be loosened to release the restriction on the adjusting plate 5, allowing the adjusting plate 5 to slide on the adjusting column 11 and be fixed in a suitable position. This facilitates adjusting the position of the adjusting plate 5 according to the material size and the spacing of the clamp. Pulling the connecting plate 14 moves the fixing column 12, causing the spring 13 to extend and retract. When the limiting plate 18 corresponds to the waterproof material, the elasticity of the spring 13 drives the limiting plate 18 to move, facilitating the restriction of the material. The pad 19 is made of rubber, which facilitates the restriction and protection of the material and allows for clamping according to the width of the material. The fixing block 17 can be loosened to rotate the fixing column 12, causing the connecting plate 14 to move and the spring 13 to extend and retract. This allows for adjusting the elasticity of the spring 13, increasing the resistance of the limiting plate 18, and facilitating clamping.
