Description

Technical Field

[0001] This utility model relates to the field of tension clamp technology, and in particular to a tension clamp for waterproof membrane. Background Technology

[0002] Waterproof membrane is a flexible sheet material used for building waterproofing. Its core function is to block water penetration and protect the building structure and interior space. It is mainly divided into asphalt-based, polymer-based, and modified asphalt-based types. It is often laid on roofs, basements, and waterproof areas in kitchens and bathrooms through hot-melt and cold-bonding methods. It has weather-resistant, impermeable, and durable properties and is a key component of building waterproofing projects.

[0003] Early roll material clamps were mainly manual wedge clamps and movable short-arm clamps. Their working principle focused on mechanical clamping. Manual wedge clamps allowed manual movement of the clamp body, with springs transmitting lateral force to horizontally clamp the sample, and the clamping force increased with the test load. Movable short-arm clamps were driven by a motor to rotate the short arm, and relied on springs and hydraulic devices to generate clamping force to fix the roll material. When released, they were opened by a corresponding mechanism. Manual clamps were laborious and inefficient, and the clamping force was difficult to adjust. Current clamps can adjust the clamping force with intelligent devices, but they cannot effectively clamp roll materials of unsuitable size, and the clamping size is limited, making them unsuitable for multi-size roll materials.

At the same time, the meshing characteristics of the worm gear and worm wheel can achieve reverse self-locking, avoiding transmission back-off due to external force after clamping. Compared with the traditional clamping structure, it is easier to operate, more accurate and reliable, and the clamping effect is significantly better. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 3This utility model provides an embodiment of a waterproof membrane stretching clamp, comprising a housing 1 and an outer frame 24. A limiting groove 3 is formed at the lower end of the outer wall of the housing 1. A rotating shaft 4 is rotatably connected to both sides of the middle of the outer wall of the housing 1. A rotating disk 5 is fixedly connected to one end of the rotating shaft 4. A gear 6 is fixedly connected to the outer wall of the rotating disk 5. A rack 7 meshes with the outer wall of the gear 6. A limiting plate 9 is fixedly connected to the inner wall of the housing 1. A connecting post 10 is fixedly connected to the lower end of the outer wall of the rack 7. A limiting groove 8 is formed on the outer wall of the rack 7. An outer frame 11 is fixedly connected to the lower end of the connecting post 10. A double-threaded stud 12 is rotatably connected to the inner wall of the outer frame 11. Multiple clamping plates 14 are rotatably connected to the outer wall of the double-threaded stud 12. The outer wall of the clamping plate 14 is slidably connected to the limit post 23. The front and rear ends of the rotating shaft 2 4 are fixedly connected to the knob 13. The outer wall of the rotating disk 3 5 is fixedly connected to the connecting plate 15. The outer wall of the connecting plate 15 is fixedly connected to the fixing post 16. The outer wall of the fixing post 16 is rotatably connected to multiple rotating modules 17. The inner wall of the multiple rotating modules 17 is rotatably connected to the rotating disk 2 18. The outer wall of the rotating disk 2 18 is fixedly connected to the straight plate 19. The top of the straight plate 19 is fixedly connected to the moving post 21. The outer wall of the moving post 21 is fixedly connected to the sleeve 20. The outer wall of the moving post 21 is rotatably connected to the gear 3 22. The inner wall of the outer frame 2 24 is fixedly connected to the support plate 25. The outer wall of the gear 3 22 is provided with a clamping mechanism 2. The clamping mechanism 2 is used to assist in clamping the roll material. Specifically, a limiting groove 3 is provided at the lower end of the outer wall of the outer casing 1. The limiting groove 3 is mainly used to initially limit the movement direction of the rack 7, preventing lateral deviation of the rack 7 during its up-and-down movement and ensuring the accuracy of transmission. Rotating shafts 4 are rotatably connected to both sides of the middle of the outer wall of the outer casing 1. As the core shaft of the transmission, rotating shaft 4 can rotate around its own axis under external force. On one hand, it drives the knobs 13 at both ends to rotate synchronously; on the other hand, it drives the rotating disk 5 and the stabilizing sleeve 36 to rotate, thus realizing the transmission of power. One end of the rotating shaft 4 is fixedly connected to the rotating disk 5, which is a key component for power conversion. Through its fixed connection with the rotating shaft 4, the rotational motion of the rotating shaft 4 is converted into the rotational power of the gear 6, simultaneously driving the connecting plate 1. 15. A rotating disk 35 is fixedly connected to a gear 26 on its outer wall. Gear 26, utilizing the gear meshing principle, cooperates with rack 27 to convert the rotational motion of rotating disk 35 into the vertical linear motion of rack 27, providing power for the lifting and lowering of outer frame 11. The outer wall of gear 26 meshes with rack 27, which, as a linear transmission component, moves vertically under the drive of gear 26. This, in turn, drives outer frame 11 to move synchronously up and down via connecting column 10, adjusting the relative position of outer frame 11 and the components below. A limiting plate 9 is fixedly connected to the inner wall of outer shell 11. The limiting plate 9 cooperates with the limiting groove 28 on the outer wall of rack 27 to further restrict the movement trajectory of rack 27, ensuring that rack 27 always moves vertically and preventing tilting. The rack 2 7 has a limiting groove 2 8 on its outer wall, which provides a sliding track for the limiting plate 9, allowing the limiting plate 9 to stably limit the rack 2 7 and enhance the stability of the rack 2 7's movement. A connecting post 10 is fixedly connected to the lower end of the outer wall of the rack 2 7. The connecting post 10 connects the rack 2 7 to the outer frame 1 11, accurately transmitting the linear movement of the rack 2 7 to the outer frame 1 11, ensuring that the outer frame 1 11 rises and falls synchronously with the rack 2 7. The lower end of the connecting post 10 is fixedly connected to the outer frame 1 11, which serves as the mounting frame for the upper clamping assembly, used to fix the double-threaded stud 12 and the limiting post 23, while also providing space for the sliding of the clamping plate 14, ensuring that the clamping plate 14 can stably clamp the waterproof membrane. The inner... The upper clamping mechanism is rotatably connected to a double-threaded stud 12. When the double-threaded stud 12 rotates under external force, the positive and negative threads on its outer wall cause the clamping plates 14 on both sides to move closer and further apart, realizing the clamping and loosening operation of the waterproof membrane. It is the core transmission component of the upper clamping mechanism. Multiple clamping plates 14 are rotatably connected to the outer wall of the double-threaded stud 12. The clamping plates 14 are clamping components that directly contact the waterproof membrane. Driven by the double-threaded stud 12, they achieve stable clamping of the waterproof membrane through sliding engagement with the limiting post 23, preventing the membrane from slipping during stretching. The outer walls of the multiple clamping plates 14 are slidably connected to the limiting post 23, which is used to limit the movement direction of the clamping plates 14, ensuring that the clamping plates 14 always move horizontally under the drive of the double-threaded stud 12.To ensure uniform clamping force on the waterproof membrane, knobs 13 are fixedly connected to both ends of the rotating shaft 2 4. Knobs 13 provide convenient force application points for the operator. Rotating knobs 13 drives the rotating shaft 2 4 to rotate, thereby activating the transmission process of the upper clamping mechanism. This allows for easy manual adjustment by the operator. A connecting plate 15 is fixedly connected to the outer wall of the rotating disk 3 5. The connecting plate 15 connects the rotating disk 3 5 to the fixed column 16, transmitting the circumferential motion of the rotating disk 3 5 to the fixed column 16, which in turn drives the rotating module 17 to move. The fixed column 16 is fixedly connected to the outer wall of the connecting plate 15, serving as the mounting shaft for the rotating module 17 and providing rotation for the rotating module 17. The fixed column 16 provides support and transmits power from the connecting plate 15 to the rotating module 17. Multiple rotating modules 17 are rotatably connected to the outer wall of the fixed column 16. Each rotating module 17 can rotate around the fixed column 16, simultaneously driving the rotating disk 18 to move. This serves to transmit power and convert the direction of motion, allowing the circular motion of the rotating disk 5 to be transformed into a specific trajectory motion of the rotating disk 18. The inner walls of the multiple rotating modules 17 are rotatably connected to the rotating disk 18. The rotating disk 18 moves under the drive of the rotating modules 17, thereby driving the straight plate 19 to move. It is a key component connecting the rotating modules 17 and the straight plate 19. The outer wall of the rotating disk 18 is fixedly connected to the straight plate 19, which is used to connect the rotating disk 17. The rotating disk 18 and the moving column 21 convert the motion of the rotating disk 18 into the linear motion of the moving column 21, thus transmitting power. The moving column 21 is fixedly connected to the top of the straight plate 19. The moving column 21 can move up and down and back and forth under the drive of the straight plate 19, while driving the sleeve 20 and the gear 22 to move synchronously, providing power to the clamping mechanism 2. The sleeve 20 is fixedly connected to the outer wall of the moving column 21. The sleeve 20 is fitted on the outer wall of the moving column 21, which protects the moving column 21 from damage caused by external collisions during movement and enhances the structural stability of the moving column 21. The gear 22 is rotatably connected to the outer wall of the moving column 21. Gear 3 22 cooperates with clamping mechanism 2 to convert the movement of moving column 21 into the power required by clamping mechanism 2, driving clamping mechanism 2 to achieve auxiliary clamping of waterproof membrane. Support plate 25 is fixedly connected to the inner wall of outer frame 24. Support plate 25 serves as a support component inside outer frame 24, used to support and fix clamping mechanism 2 components, enhancing the stability of the internal structure of outer frame 24 and ensuring the normal operation of clamping mechanism 2. The outer wall of gear 3 22 is equipped with clamping mechanism 2, which is used to assist in clamping the membrane, further enhancing the clamping effect on the waterproof membrane based on the main clamping mechanism, preventing the membrane from loosening during stretching, and ensuring the accuracy of tensile testing.

[0019] Please see the appendix Figure 1 Appendix Figure 6 and attached Figure 7The clamping mechanism 2 includes a support column 201 and a second outer shell 205. A slide plate 202 is fixedly connected to the outer wall of the support column 201. A groove 203 is opened on the outer wall of the slide plate 202. A rack 204 is slidably connected to the inner wall of the groove 203. A worm 209 is rotatably connected to the outer wall of the second outer shell 205. A worm wheel 208 is meshed on the outer wall of the worm 209. A rotating disk 210 is fixedly connected to one end of the worm 209. A rotating shaft 206 is rotatably connected to the inner wall of the second outer shell 205. A rotating base 211 is rotatably connected to the lower end of the rotating shaft 206. An L-shaped plate 212 is rotatably connected to the upper end of the rotating shaft 206. A gear 207 is fixedly connected to the upper end of the rotating shaft 206. Specifically, the support column 201 serves as the supporting foundation for the clamping mechanism 2, used to fix the slide plate 202 and stably install the clamping mechanism 2 inside the outer frame 24, ensuring the overall stability of the clamping mechanism 2. The slide plate 202 is fixedly connected to the outer wall of the support column 201. The slide plate 202 provides a sliding support surface for the rack 204, allowing the rack 204 to slide stably within the groove 203, while also restricting the direction of movement of the rack 204. The outer wall of the slide plate 202 has a groove 203, which is the sliding track for the rack 204. To ensure that rack 204 does not deviate during sliding and to guarantee precise meshing between rack 204 and gear 207, rack 204 is slidably connected to the inner wall of slide groove 203. Through meshing with gear 22 and gear 207, rack 204 transmits the power of gear 22 to gear 207, achieving power transmission and conversion, and providing power for the clamping action of clamping mechanism 2. A worm gear 209 rotates on the outer wall of outer shell 205. The worm gear 209 serves as a manually driven component; its rotation drives worm wheel 208 to rotate. To drive the rotating shaft 206, the self-locking characteristics of the worm gear 209 and worm wheel 208 are utilized to ensure that it will not loosen after clamping. The outer wall of the worm gear 209 is meshed with the worm wheel 208. The worm wheel 208 cooperates with the worm gear 209 to convert the rotational motion of the worm gear 209 into its own rotational power, which is then transmitted to the rotating shaft 206, realizing the deceleration and direction change of the power. One end of the worm gear 209 is fixedly connected to a rotating disk 210, which provides the operator with a point of force to manually rotate the worm gear 209, facilitating the operator's operation. The clamping degree of the clamping mechanism 2 is adjusted by rotating the rotating disk 210. The inner wall of the outer shell 205 is rotatably connected to the rotating shaft 206. The rotating shaft 206 is the core rotating shaft of the clamping mechanism 2. It rotates under the drive of the worm gear 208 and the gear 207, which in turn drives the L-shaped plate 212 to rotate, thereby realizing the clamping action. The lower end of the rotating shaft 206 is rotatably connected to the rotating base 211. The rotating base 211 provides rotational support for the lower end of the rotating shaft 206, reduces friction when the rotating shaft 206 rotates, and ensures the smoothness of the rotation of the rotating shaft 206.

The outer wall of the lamp holder 32 is fixedly connected to a lighting lamp 33. Specifically, a base plate 28 is fixedly connected to the bottom end of the outer frame 24. The base plate 28 is the bottom support structure of the entire fixture, used to stably place the fixture on the ground and workbench, and also provides a location for the mounting holes 29 to facilitate the fixed installation of the fixture. Mounting holes 29 are provided near the edge of the outer wall of the base plate 28. The mounting holes 29 are used to fix the base plate 28 to the ground and workbench with bolts, thereby achieving a fixed installation of the entire fixture and preventing movement during operation. A label 30 is fixedly connected to the left end of the outer wall of the outer frame 24. The label 30 is used to indicate the model, specifications, instructions for use, and manufacturer information of the fixture, making it convenient for operators to identify and view the relevant parameters of the fixture. A controller 31 is fixedly connected to the right end of the outer wall of frame 24. The controller 31 serves as the control core of the fixture, controlling the switching of the lighting lamp 33 and adjusting the operating parameters of the clamping mechanism to achieve automated control of some functions of the fixture and improve the ease of operation. A lamp holder 32 is fixedly connected to the inner wall of the outer frame 24. The lamp holder 32 is used to fix the lighting lamp 33, providing a stable installation base for the lighting lamp 33, and also realizing the electrical connection between the lighting lamp 33 and the power supply. The lighting lamp 33 is fixedly connected to the outer wall of the lamp holder 32. The lighting lamp 33 is turned on and off under the control of the controller 31, providing illumination for operation and observation inside the fixture in low-light environments, facilitating clamping and stretching operations by the operator.

[0021] Please see the appendix Figure 2 Appendix Figure 3 and attached Figure 4 The outer wall of the outer frame 11 is fixedly connected with a washer 34, the top of the outer shell 11 is fixedly connected with a pull rod 35, the outer wall of the rotating shaft 24 is fixedly connected with a stabilizing sleeve 36, the outer wall of the clamping plate 14 is fixedly connected with an anti-slip pad 37, the bottom of the sleeve 20 is fixedly connected with a protective sleeve 27, and a protective sleeve 1 26 is provided above the gear 3 22. Specifically, a washer 34 is fixedly connected to the outer wall of the outer frame 11. The washer 34 is made of elastic material.

On the other hand, it enhances the sealing of the connection between the outer frame 11 and related components to prevent dust and impurities from entering the inner shell 11. A pull rod 35 is fixedly connected to the top of the outer shell 1. The pull rod 35 provides operators with convenient handling and movement of the upper structure components of the fixture. By pulling the pull rod 35, the outer shell 1 and its related components can be easily moved, facilitating the installation, debugging and handling of the fixture. A stabilizing sleeve 36 is fixedly connected to the outer wall of the rotating shaft 2 4. The stabilizing sleeve 36 is fitted on the outer wall of the rotating shaft 2 4 to enhance the structural stability of the rotating shaft 2 4, prevent the rotating shaft 2 4 from bending and shaking during rotation, and ensure the accuracy of the transmission of the rotating shaft 2 4. Clamping plate 14 The outer wall is fixedly connected to the anti-slip pad 37, which is made of a material with a high coefficient of friction. It is attached to the surface of the clamping plate 14 that contacts the waterproof membrane, which can effectively increase the friction between the clamping plate 14 and the membrane, prevent the membrane from slipping during clamping and stretching, and ensure the accuracy of the tensile test. The bottom end of the sleeve 20 is fixedly connected to the protective sleeve 27. The protective sleeve 27 is used to protect the bottom end of the sleeve 20, prevent the sleeve 20 from colliding with the lower parts during movement and causing damage, and at the same time prevent dust and impurities from entering the sleeve 20 and affecting its normal operation. The gear 3 22 is provided with a protective sleeve 1 26. The protective sleeve 1 26 is placed on top of the gear 3 22 to protect the gear 3 22 from external dust and impurities, and at the same time prevent the operator from accidentally touching the gear 3 22 during operation and causing a safety accident, and ensure the normal meshing and transmission of the gear 3 22.

[0022] Working principle: Rotating gear 3 22, due to the internal threads of gear 3 22, drives the moving column 21 to move downward. The movement of gear 3 22 drives the straight plate 19, rotating disk 2 18, rotating module 17, fixed column 16, connecting plate 1 15, rotating disk 3 5, and gear 2 6 to move periodically, thereby driving the rack 2 7 meshing with gear 2 6 to move. Finally, it drives the clamping plate 14 below to complete the clamping and opening action. The clamping range of clamping plate 14 can be adjusted by turning knob 13 to drive double threaded stud 12 to drive clamping plate 14 to slide on double threaded stud 12 and limit column 23, so that the clamping range of clamping plate 14 can be adjusted to adapt to a wide range and can clamp more sizes of coiled material. Rotating the rotating disk 210 causes the worm gear 209 to rotate, which in turn drives the worm wheel 208. The rotation of the worm wheel 208 drives the rotating shaft 206, which in turn drives the gear 207 fixedly connected to it to rotate. The gear 207 meshes with the rack 204, so the rotation of the gear 207 causes the rack 204 to move along the groove 203 on the slide plate 202, thereby causing the gear 22 meshing with the rack 204 to rotate. This achieves force-assisted clamping of the clamping mechanism, resulting in a better clamping effect.
