Description

Technical Field

[0001] This utility model relates to the field of rubber tube testing technology, and in particular to a tensile testing machine for rubber tubes. Background Technology

[0002] Rubber hoses are flexible tubes made of rubber material, widely used in various fields due to their unique flexibility and durability. Common types of rubber hoses include natural rubber hoses, synthetic rubber hoses, heat-resistant rubber hoses, and corrosion-resistant rubber hoses.

[0003] Rubber is an indispensable material for social development, being a highly elastic polymer compound. Because rubber parts are organic materials, the final product requires quality testing, and a rubber hose tensile testing machine is a device specifically designed to test the tensile properties of rubber hoses.

[0004] Traditional rubber hose testing devices connect the rubber hose to a tension gauge and manually pull the tension gauge to test the rubber hose's expansion and contraction limits. Because it is a manual pulling factor, the test results are inaccurate and the testing stability is poor. In addition, the rubber hose to be tested is usually fixed manually, which can easily lead to insecure fixing and affect the test results. Therefore, a tensile testing machine for rubber hoses is proposed. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the inaccuracy of test results due to manual pulling and the instability of the rubber tube, which also affects the test results. Therefore, this invention proposes a tensile testing machine for rubber tubes.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A tensile testing machine for rubber hoses includes a worktable, a first housing fixedly connected to the upper part of the worktable, a second housing slidably connected to the upper part of the worktable, a tensile sensing device fixedly connected to the outer side of the second housing, a fixing component between the second housing and the first housing, the fixing component including a first clamp and a second clamp, and a tensile component including a threaded rod on the worktable.

[0008] The above technical solution further includes:

[0009] The second housing has symmetrically fixed convex blocks on one side near the workbench, and the workbench has symmetrically opened convex grooves on one side near the second housing. The convex blocks and convex grooves are slidably connected.

[0010] A support plate is fixedly connected to the side of the workbench near the second housing. The support plate is threadedly connected to the threaded rod, and the threaded rod is fixedly connected to the tension sensing device.

[0011] A motor is fixedly connected to the side of the support plate away from the second housing. A worm gear is fixedly connected to the end of the output shaft of the motor. A worm wheel is movably connected to the outside of the support plate. The worm wheel is threadedly connected to the threaded rod. The worm wheel and the worm gear mesh with each other, which can continuously and stably apply tensile force to the rubber tube sample, thereby improving the accuracy and efficiency of the test.

[0012] Both the second box and the first box are fixedly connected to a telescopic device on the side away from the workbench. A push rod is movably connected to the bottom of the telescopic device. The push rod is movably connected to the workbench. A third connecting rod is symmetrically movably connected to the end of the push rod away from the telescopic device.

[0013] The first housing has symmetrically fixed support rods inside, and cylindrical rings are movably connected to the outer sides of both support rods. Push rods are fixedly connected to the outer sides of the cylindrical rings.

[0014] The first housing is symmetrically and movably connected to a first connecting rod, and the two first connecting rods are movably connected to a third connecting rod. The push rod is symmetrically and movably connected to a second connecting rod on the side near the telescopic device.

[0015] The end of the second connecting rod away from the push rod is movably connected to the third connecting rod, and the end of the second connecting rod away from the push rod is movably connected to the first connecting rod. The side of the push rod away from the telescopic device is fixedly connected to the first clamp, and the first box is fixedly connected to the second clamp. This configuration allows for continuous and stable application of tensile force to the rubber tube sample, improving the accuracy and efficiency of the test.

[0016] This utility model has the following beneficial effects:

[0017] 1. In this utility model, the fixing component can firmly clamp the rubber tube sample, preventing the sample from slipping during the tensile test, thereby ensuring the accuracy and reliability of the test data. It can also adapt to rubber tube samples of different specifications and sizes, eliminating the need for frequent clamp replacements and improving testing efficiency.

[0018] 2. In this utility model, the tension component can continuously and stably apply tension to the rubber tube sample, which improves the accuracy and efficiency of the test, reduces the error and uncertainty in the test process, and avoids the instability of manual pulling.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0025] Example 1

[0026] like Figures 1-4 As shown, the present invention proposes a tensile testing machine for rubber tubes, including a workbench 1, a first housing 8 fixedly connected to the upper part of the workbench 1, a second housing 17 slidably connected to the upper part of the workbench 1, a tensile sensing device 7 fixedly connected to the outer side of the second housing 17, a fixing component provided between the second housing 17 and the first housing 8, the fixing component including a first clamp 19 and a second clamp 20, a telescopic device 9 fixedly connected to the side of the second housing 17 and the first housing 8 away from the workbench 1, a push rod 15 movably connected to the bottom of the telescopic device 9, and the push rod 15 movably connected to the workbench 1;

[0027] A third connecting rod 18 is symmetrically and movably connected to the end of the push rod 15 away from the telescopic device 9. A support rod 12 is symmetrically and fixedly connected inside the first housing 8. A cylindrical ring 16 is movably connected to the outer side of each of the two support rods 12. A push rod 15 is fixedly connected to the outer side of the cylindrical ring 16. A first connecting rod 13 is symmetrically and movably connected inside the first housing 8. Both first connecting rods 13 are movably connected to the third connecting rod 18. A second connecting rod 14 is symmetrically and movably connected to the side of the push rod 15 near the telescopic device 9. The end of the second connecting rod 14 away from the push rod 15 is movably connected to the third connecting rod 18. The end of the second connecting rod 14 away from the push rod 15 is movably connected to the first connecting rod 13. The side of the push rod 15 away from the telescopic device 9 is fixedly connected to the first clamp 19. The first housing 8 is fixedly connected to the second clamp 20.

[0028] In this embodiment, the rubber tube is placed at both ends on the second clamps 20 inside the second housing 17 and the first housing 8, respectively. The push rod 15 of the telescopic device 9 pushes the third connecting rod 18. The third connecting rod 18 moves along with the push rod 15, causing the first connecting rod 13 and the second connecting rod 14 to follow. As the push rod 15 pushes downward, the second connecting rod 14 causes the push rod 15 and the cylindrical ring 16 to slide downward on the support rod 12, so that the first clamp 19 follows the push rod 15 downward to press the rubber tube placed on the second clamp 20, thereby fixing the rubber tube. The mechanical fixing solves the problem of slippage when manually fixed.

[0029] Example 2

[0030] like Figures 1-4 As shown, based on Embodiment 1, a tension assembly is provided on the workbench 1. The tension assembly includes a threaded rod 4. A convex block 11 is symmetrically fixedly connected to the side of the second housing 17 near the workbench 1. A convex groove 10 is symmetrically opened on the side of the workbench 1 near the second housing 17. The convex block 11 and the convex groove 10 are slidably connected. A support plate 2 is fixedly connected to the side of the workbench 1 near the second housing 17. The support plate 2 is threadedly connected to the threaded rod 4. The threaded rod 4 is fixedly connected to the tension sensing device 7. A motor 6 is fixedly connected to the side of the support plate 2 away from the second housing 17. A worm gear 5 is fixedly connected to the end of the output shaft of the motor 6. A worm wheel 3 is movably connected to the outside of the support plate 2. The worm wheel 3 is threadedly connected to the threaded rod 4. The worm wheel 3 and the worm gear 5 mesh with each other.

[0031] In this embodiment, as described in the previous step, the starting of the motor 6 drives the rotation of the worm 5. The worm 5 meshes with the worm wheel 3. The rotation of the worm 5 drives the rotation of the worm wheel 3. The worm wheel 3 meshes with the threaded rod 4. The rotation of the worm wheel 3 drives the rotation of the threaded rod 4. The threaded rod 4 meshes with the support plate 2. The rotation of the threaded rod 4 causes the second housing 17 to slide in the convex groove 10, thereby pulling the rubber tube fixed on the second housing 17 and the first housing 8. The tension sensing device 7 provides feedback on the stretching effect, avoiding the instability of manual pulling and improving the accuracy and efficiency of the test.
