Description

Technical Field

[0001] This utility model relates to the technical field of the construction industry, and more specifically, it relates to a testing fixture for building waterproofing materials. Background Technology

[0002] In the construction industry, many products such as wall materials, building steel, waterproof materials, plastics, and wood need to be tested for performance before they are approved for use. Testing waterproof boards requires the use of different clamps.

[0003] In the testing of building waterproofing materials, quick and accurate clamping of the material is key to ensuring testing efficiency and accuracy. Existing automated clamps are slow to react during the clamping process and cannot respond quickly to operation commands, resulting in increased waiting time during the testing process. This slow response seriously affects testing efficiency, especially in situations where the test material needs to be changed frequently. For example, when conducting batch testing, each material change requires waiting for the clamp to complete the clamping action, which not only wastes time but may also affect the continuity and accuracy of the testing.

[0004] In the testing of building waterproofing materials, in order to ensure that all parts of the material are fully tested, the material needs to be rotated and adjusted in all directions. However, existing automated fixtures can often only be used for testing at fixed angles and positions, and cannot easily rotate the material for testing without blind spots. This not only limits the scope of testing, but may also lead to the omission of testing some critical parts. For example, when testing the surface flatness and uniformity of waterproofing materials, it is necessary to observe and measure from multiple angles. Existing fixtures cannot meet this requirement, resulting in incomplete and inaccurate test results. Utility Model Content

[0005] (1) Technical problems solved

[0006] To address the problems existing in the prior art, this utility model provides a building waterproof material testing fixture, which solves the technical problems mentioned in the background art, such as the slow response of existing automated fixtures during the clamping process, the inability to quickly respond to operation commands, and the inability to conveniently perform rotational testing of materials without blind spots.

[0007] (2) Technical solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a building waterproofing material testing fixture, comprising a base frame, on which a clamping mechanism is provided. The clamping mechanism includes a mounting plate, a support plate, a pressure rod, a clamping plate, a pressure plate, a cylinder, and a top block. The mounting plate is disposed on the inner side of the base frame. Multiple sets of support plates are provided and mounted on the mounting plate. The pressure rod is slidably mounted on the multiple sets of support plates. The clamping plate is mounted on the bottom end of the multiple sets of pressure rods. The pressure plate is rotatably mounted on the multiple sets of support plates. Multiple sets of cylinders are provided and mounted on the top block. On the mounting plate, the top block is mounted on the telescopic ends of multiple sets of cylinders. The mounting plate is provided with an adjustment mechanism, which includes a rotating shaft, slots, a fixing sleeve, a fixing block, a pop-out spring, and a locking mechanism. The rotating shaft is mounted on the outside of the mounting plate and is rotatably connected to the base frame. Multiple slots are provided and distributed on the outside of the rotating shaft. The fixing sleeve is mounted on the outside of the base frame. Multiple fixing blocks are provided and slidably mounted on the fixing sleeve. The pop-out spring is mounted on the top of the multiple sets of fixing blocks and connected to the outer wall of the fixing sleeve.

[0009] The present invention is further configured such that each of the multiple sets of pressure rods has a stop block at its top, and the top of each of the multiple sets of stop blocks is a rounded surface. This design reduces the friction between the pressure rod and the pressure plate, making the pressure rod slide more smoothly, improving the clamping efficiency and stability, and extending the service life of the equipment.

[0010] The present invention is further provided that the bottom surface of each of the multiple sets of clamping plates is provided with a soft pad. The design of the soft pad protects the surface of the waterproof material, prevents damage during clamping, and ensures the integrity of the material and the accuracy of the test.

[0011] The present invention is further configured such that all of the multiple sets of top blocks are cylindrical. The cylindrical top block design improves the stability of the top block pushing the pressure plate and reduces the risk of displacement and jamming.

[0012] The present invention is further configured such that each of the multiple sets of clamping plates is provided with a limiting plate on its top surface, and each of the multiple sets of limiting plates is slidably connected to the multiple sets of support plates. The design of the limiting plate ensures the stability of the clamping plates during movement and prevents the clamping plates from shifting.

[0013] The present invention is further provided that each of the multiple sets of clamping plates and the support plate is provided with a tension spring. The design of the tension spring ensures that the clamping plates can be quickly reset through elastic restoring force, thereby improving the efficiency of clamping and releasing.

[0014] The present invention is further configured such that a limiting block is provided on the outer wall of the rotating shaft, and a limiting groove is provided inside the fixing sleeve. The limiting block is slidably installed in the limiting groove. The design of the limiting block and the limiting groove ensures the stability and accuracy of the rotating shaft during rotation and prevents the rotating shaft from deviating.

[0015] The present invention is further configured such that the locking mechanism includes a side plate, a central rod, a connecting block, an arc-shaped block, a push spring, and a handle. The side plate is installed on the outside of the base frame, the central rod is slidably installed on the side plate, the connecting block is installed at the bottom end of the central rod, the arc-shaped block is installed at the bottom end of the connecting block, the opposite ends of the push spring are respectively connected to the side plate and the connecting block, and the handle is installed at the top end of the central rod, thereby realizing quick locking and unlocking of the rotating shaft.

[0016] (3) Beneficial effects

[0017] Compared with the prior art, this utility model provides a testing fixture for building waterproofing materials, which has the following beneficial effects:

[0018] 1. The clamping mechanism achieves rapid and stable clamping of waterproof materials through the coordinated action of the mounting plate, support plate, pressure rod, clamping plate, pressure plate, cylinder, and top block. This design not only improves clamping efficiency but also ensures clamping stability, preventing material displacement during the testing process. In addition, multiple pressure rods are equipped with abutments at their top ends, with the abutment tops being rounded to reduce friction between the pressure rods and support plates, making the pressure rods slide more smoothly. Multiple clamping plates are equipped with soft pads on their bottom surfaces to protect the surface of the waterproof materials and prevent damage during clamping.

[0019] 2. The adjustment mechanism, through the cooperation of a rotating shaft, a slot, a fixed sleeve, a fixed block, a spring, and a locking mechanism, achieves flexible adjustment of the clamping angle. When the clamping angle of the plate needs to be adjusted, the locking mechanism releases the locking of multiple fixed blocks. The multiple springs elastically reset and pull the fixed blocks outward, causing the bottom of the multiple fixed blocks to move out of the slot, thereby releasing the lock on the rotating shaft. This allows the rotating shaft to drive the mounting plate to rotate, adjusting the angle of the plate. This design enables the clamping mechanism to adapt to different detection angle adjustments, ensuring the comprehensiveness and accuracy of the detection. A limit block is installed on the outer wall of the rotating shaft, and a limit groove is opened in the fixed sleeve. The limit block is slidably installed in the limit groove to ensure that the rotating shaft will not deviate during rotation, further improving the stability of the adjustment.

[0020] 3. The locking mechanism, through the coordinated action of the side plate, central rod, connecting block, arc block, push spring, and handle, achieves rapid locking and unlocking of the rotating shaft. The push spring pushes the connecting block to move, and the connecting block pushes the arc block to abut against the tops of multiple sets of fixed blocks and squeezes multiple sets of pop-out springs, causing the bottom ends of the multiple sets of fixed blocks to engage in the slots, thus locking the rotating shaft. When it is necessary to unlock, pull the handle to move the central rod along the side plate. The central rod pulls the connecting block and arc block to slide outward while squeezing the push spring, releasing the abutment of the arc block against the tops of the multiple sets of fixed blocks, thereby unlocking the rotating shaft. This design is not only easy to operate, but also ensures the fixation of the rotating shaft after adjustment, preventing displacement during the detection process and improving the stability and accuracy of the detection.

[0031] Please see Figures 1-6 A building waterproofing material testing fixture includes a base frame 1, on which a clamping mechanism is mounted. The clamping mechanism includes a mounting plate 2, a support plate 3, pressure rods 4, clamping plates 5, pressure plates 6, cylinders 7, and a top block 8. The mounting plate 2 is located inside the base frame 1. Multiple sets of support plates 3 are mounted on the mounting plate 2. The pressure rods 4 are slidably mounted on the multiple sets of support plates 3. The clamping plates 5 are mounted on the bottom ends of the multiple sets of pressure rods 4. The pressure plates 6 are rotatably mounted on the multiple sets of support plates 3. Multiple sets of cylinders 7 are mounted on the mounting plate 2. The top block 8 is mounted on the multiple sets of support plates 3. The telescopic end of the cylinder 7 is provided with an adjustment mechanism on the mounting plate 2. The adjustment mechanism includes a rotating shaft 9, a slot 10, a fixing sleeve 11, a fixing block 12, a pop-out spring 13, and a locking mechanism. The rotating shaft 9 is installed on the outside of the mounting plate 2 and is rotatably connected to the base frame 1. Multiple slots 10 are provided and distributed on the outside of the rotating shaft 9. The fixing sleeve 11 is installed on the outside of the base frame 1. Multiple fixing blocks 12 are provided and slidably installed on the fixing sleeve 11. The pop-out spring 13 is installed on the top of the multiple fixing blocks 12 and is connected to the outer wall of the fixing sleeve 11.

[0032] Each of the multiple pressure rods 4 has a stop block 14 at its top, and the top of each of the multiple stop blocks 14 is set as an arc surface. The arc surface design reduces the friction between the pressure rod 4 and the pressure plate 6, making the pressure rod 4 slide more smoothly.

[0033] The bottom surface of each set of clamps 5 is provided with a soft pad 15. The soft pad 15 is usually made of a soft and elastic material, such as rubber or silicone, which can effectively protect the surface of the waterproof material.

[0034] All sets of top blocks 8 are set in a cylindrical shape. The cylindrical design makes the top blocks 8 more stable when pushing the pressure plate 6, reducing the risk of displacement and jamming.

[0035] Each set of clamping plates 5 has a limiting plate 16 on its top surface. The multiple sets of limiting plates 16 are slidably connected to the multiple sets of support plates 3. This design ensures the linear movement of the clamping plates 5 through the sliding connection of the limiting plates 16.

[0036] Multiple clamping plates 5 are provided with tension springs 17 between them and the support plate 3. The elastic restoring force of the tension springs 17 ensures that the clamping plates 5 can be quickly reset.

[0037] A limiting block 18 is installed on the outer wall of the rotating shaft 9, and a limiting groove 19 is opened in the fixed sleeve 11. The limiting block 18 is slidably installed in the limiting groove 19. When the rotating shaft 9 rotates, the limiting block 18 slides in the limiting groove 19 to ensure that the rotating shaft 9 will not deviate during the rotation process.

[0038] In this embodiment, the waterproof sheet is placed between the clamping plates 5, ensuring it is flat. The cylinder 7 is activated, causing its telescopic end to push the top block 8 against the top surface of the pressure plate 6. The top block 8 pushes the pressure plate 6 so that its bottom surface abuts against the abutment block 14, applying downward pressure. This causes the push rod to move the clamping plate 5. When the clamping plate 5 moves, the limiting plate 16 slides along the support plate 3 to maintain the stability of the clamping plate 5, while simultaneously stretching the tension spring 17. This causes the soft pad 15 on the clamping plate 5 to contact the side wall of the sheet, thus clamping the sheet. Conversely, the cylinder 7 is activated to retract its telescopic end, releasing the pressure plate from the top block 8. The contact of 6 causes the clamping plate 5 to be pulled by the elastic reset of the tension spring 17, which causes the push rod to move upward and push the pressure plate 6 to rotate through the abutment block 14, thereby releasing the clamping of the plate. However, when it is necessary to adjust the clamping angle of the plate, the locking mechanism is released from locking the multiple sets of fixing blocks 12. The multiple sets of pop-out springs 13 elastically reset and pull the fixing blocks 12 to slide outward, so that the bottom of the multiple sets of fixing blocks 12 moves out of the slot 10, thereby releasing the lock on the rotating shaft 9, so that the rotating shaft 9 can drive the mounting plate 2 to rotate and adjust the angle of the plate. Then, the rotating shaft 9 is locked again by the locking mechanism.

[0039] Please see Figures 5-6 As one embodiment of the locking mechanism: the locking mechanism includes a side plate 20, a central rod 21, a connecting block 22, an arc-shaped block 23, a push spring 24, and a handle 25. The side plate 20 is installed on the outside of the base frame 1. The central rod 21 is slidably installed on the side plate 20. The connecting block 22 is installed at the bottom end of the central rod 21. The arc-shaped block 23 is installed at the bottom end of the connecting block 22. The two opposite ends of the push spring 24 are respectively connected to the side plate 20 and the connecting block 22. The handle 25 is installed at the top end of the central rod 21.

[0040] More specifically, the push spring 24 pushes the connecting block 22 to move, and the connecting block 22 pushes the arc-shaped block 23 to abut against the top of the multiple sets of fixed blocks 12 and squeeze the multiple sets of pop-out springs 13, so that the bottom of the multiple sets of fixed blocks 12 is engaged in the slot 10, locking the rotating shaft 9. When it is necessary to unlock, pull the handle 25 to drive the center rod 21 to slide along the side plate 20. The center rod 21 pulls the connecting block 22 and the arc-shaped block 23 to slide outward and squeezes the push spring 24 at the same time, releasing the abutment of the arc-shaped block 23 against the top of the multiple sets of locking blocks, thereby unlocking the rotating shaft 9.

[0041] In summary, during the use or operation of the entire equipment: Place the waterproof sheet between the clamping plates 5, ensuring it is flat. Start the cylinder 7, causing its telescopic end to push the top block 8 against the top surface of the pressure plate 6. The top block 8 then pushes the pressure plate 6 so that its bottom surface abuts against the abutment block 14, applying downward pressure. This causes the push rod to move the clamping plate 5. As the clamping plate 5 moves, the limiting plate 16 slides along the support plate 3 to maintain its stability, while simultaneously stretching the tension spring 17. This causes the soft pad 15 on the clamping plate 5 to contact the side wall of the sheet, thus clamping the sheet. Conversely, retract the telescopic end of the cylinder 7 to release the pressure. The contact between block 8 and pressure plate 6 causes the clamping plate 5 to be pulled back by spring 17, which in turn causes the push rod to move upward and push the pressure plate 6 to rotate through block 14, thereby releasing the clamping of the plate. However, when it is necessary to adjust the clamping angle of the plate, the locking mechanism is released from locking multiple sets of fixing blocks 12. Multiple sets of pop-out springs 13 are used to pull the fixing blocks 12 outward, causing the bottom of the multiple sets of fixing blocks 12 to move out of the slot 10, thereby releasing the lock on the rotating shaft 9. This allows the rotating shaft 9 to drive the mounting plate 2 to rotate and adjust the angle of the plate. Then, the rotating shaft 9 is locked back in place by the locking mechanism.

[0042] The push spring 24 pushes the connecting block 22 to move. The connecting block 22 pushes the arc-shaped block 23 to abut against the top of the multiple sets of fixed blocks 12 and squeeze the multiple sets of pop-out springs 13, so that the bottom of the multiple sets of fixed blocks 12 is engaged in the slot 10, locking the rotating shaft 9. When it is necessary to unlock, pull the handle 25 to drive the center rod 21 to slide along the side plate 20. The center rod 21 pulls the connecting block 22 and the arc-shaped block 23 to slide outward and squeezes the push spring 24 at the same time, releasing the abutment of the arc-shaped block 23 against the top of the multiple sets of locking blocks, thereby unlocking the rotating shaft 9.

[0043] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
