Description

Technical Field

[0001] This utility model relates to the field of rubber sealing ring technology, specifically to an O-ring rubber sealing ring tensile testing device. Background Technology

[0002] Rubber seals are commonly used to seal oil, water, air, gas and various chemical media. To ensure the sealing effect of rubber seals, it is often necessary to test them for tensile strength, elastic modulus, elongation and aging resistance.

[0003] In most existing O-ring tensile testing devices, the tensile gauge is integrated with the testing device. When the tensile gauge malfunctions and cannot perform the test, the entire testing device needs to be replaced, which greatly increases the cost of use. In addition, existing testing devices lack protective devices. When the rubber seal breaks and splashes, it can easily injure workers, making it inconvenient for workers to use. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an O-ring tensile testing device to solve the problems mentioned in the background art. In most existing O-ring tensile testing devices, the tensile gauge is integrated with the testing device. When the tensile gauge malfunctions and cannot perform the test, the entire testing device needs to be replaced, which greatly increases the cost of use. In addition, existing testing devices lack protective devices, and when the rubber seal breaks and splashes, it is easy to accidentally injure the staff, making it inconvenient for staff to use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an O-ring rubber seal tensile testing device, comprising a base, a support leg fixedly connected to the bottom of the base, a servo motor fixedly connected to the right end of the base, an installation groove provided on the top right side of the base, a lead screw rotatably connected inside the installation groove, a threaded block threadedly connected to the surface of the lead screw, a pull hook fixedly connected to the top left end of the threaded block, a baffle fixedly connected to the top left side of the base, a tension gauge provided on the left side of the baffle, a pull hook provided at the right end of the tension gauge, an installation block fixedly connected to the top left side of the base, a threaded rod threadedly connected inside the installation block, a limit block fixedly connected to the inner side of the threaded rod, a mounting seat fixedly connected to the top right side of the base, an electric push rod fixedly connected to the top of the mounting seat, a protective cover fixedly connected to the bottom of the electric push rod, and a notch provided on the left side of the protective cover.

[0006] Preferably, the output end of the servo motor extends through the right wall of the base into the interior of the mounting groove and is fixedly connected to the right end of the lead screw.

[0007] By adopting the above technical solution, a servo motor, lead screw, and other components are used in conjunction with a threaded block. The servo motor drives the lead screw to rotate, thereby moving the threaded block. The movement of the threaded block then drives the hook to pull the O-ring rubber seal, eliminating the need for manual stretching by workers and reducing their labor intensity.

[0008] Preferably, the width of the threaded block is the same as the width of the mounting groove, and the threaded block is in close contact with the inner wall of the mounting groove.

[0009] Preferably, there are two mounting blocks, which are symmetrically distributed on the front and rear sides of the top of the base, and both mounting blocks are threaded with threaded rods inside.

[0010] By using the above technical solution, and by setting up an installation block, a threaded rod, etc. in conjunction with a baffle, the limit block can be separated from the tension gauge by rotating the threaded rod, thus releasing the locking of the tension gauge. At this time, the tension gauge can be replaced by the staff. The operation is simple and convenient, without the need to replace the entire testing device, making it convenient for staff to use.

[0011] Preferably, there are two baffles, which are symmetrically distributed on the front and rear sides of the top of the base, and the distance between the two baffles is greater than the width of the mounting groove.

[0012] Preferably, the protective cover is located directly above the mounting groove, and the protective cover is made of transparent acrylic material.

[0013] By adopting the above technical solution and using protective covers and mounting slots in conjunction, the protective cover can completely cover hook one and hook two, allowing staff to observe the internal situation through the protective cover. When the O-ring rubber seal exceeds its tensile limit and breaks off and splashes, it will be blocked by the protective cover, preventing accidental injury to staff and facilitating use.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This O-ring rubber seal tensile testing device uses a mounting block, threaded rod, and baffle. By rotating the threaded rod, the limit block can be separated from the tensile gauge, releasing the lock on the tensile gauge. At this time, the tensile gauge can be replaced by the operator. The operation is simple and convenient, without the need to replace the entire testing device, which reduces the cost of use and makes it convenient for operators to use.

[0016] 2. This O-ring rubber seal tensile testing device, through the use of a protective cover and mounting groove, can completely cover hook one and hook two, allowing staff to observe the internal situation through the protective cover. When the O-ring rubber seal exceeds its tensile limit and breaks and splashes, it will be blocked by the protective cover, preventing accidental injury to staff and facilitating its use.

[0023] 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.

[0024] Example 1:

[0025] Referring to Figures 1-4, an O-ring rubber seal tensile testing device includes a base 1. A support leg 2 is fixedly connected to the bottom of the base 1. A servo motor 5 is fixedly connected to the right end of the base 1. A mounting groove 3 is formed on the top right side of the base 1. A lead screw 4 is rotatably connected inside the mounting groove 3. The output end of the servo motor 5 extends through the right wall of the base 1 into the mounting groove 3 and is fixedly connected to the right end of the lead screw 4. A threaded block 6 is threaded onto the surface of the lead screw 4. The width of the threaded block 6 is the same as the width of the mounting groove 3, and the threaded block 6 fits tightly against the inner wall of the mounting groove 3. A pull hook 7 is fixedly connected to the top left end of the threaded block 6. The top left side of the base 1 is fixed... Two baffles 8 are connected to the base 1. The two baffles 8 are symmetrically distributed on the front and rear sides of the top of the base 1, and the distance between the two baffles 8 is greater than the width of the mounting groove 3. A tension gauge 9 is provided on the left side of the baffle 8, and a pull hook 10 is provided on the right end of the tension gauge 9. A mounting block 11 is fixedly connected to the top left side of the base 1. A threaded rod 12 is connected to the inside of the mounting block 11. A limit block 13 is fixedly connected to the inside of the threaded rod 12. A mounting seat 14 is fixedly connected to the top right side of the base 1. An electric push rod 15 is fixedly connected to the top of the mounting seat 14. A protective cover 16 is fixedly connected to the bottom of the electric push rod 15. A notch 17 is opened on the left side of the protective cover 16.

[0026] Working Principle: During use, the operator simply places the O-ring to be tested onto hook 7 and hook 10. Then, the servo motor 5 is activated. The servo motor 5 drives the lead screw 4 to rotate via its output, which in turn moves the threaded block 6 to the right. The movement of the threaded block 6 then moves hook 7, stretching the O-ring. The tensile strength of the O-ring is obtained by reading the value on the tension gauge 9. If the tension gauge 9 malfunctions and affects the test, the operator simply rotates the threaded rod 12 to separate the limit block 13 from the tension gauge 9, releasing the lock. The operator then removes the damaged tension gauge 9 and places a new tension gauge 9 on top of the base 1, fitting it against the baffle 8. Rotating the threaded rod 12 then pushes the limit block 13 to relock the tension gauge 9. The operation is simple and convenient, requiring no replacement of the entire testing device, reducing operating costs and making it easier for operators to use.

[0027] Compared with related technologies, the O-ring tensile testing device provided by this utility model has the following advantages: by setting up the mounting block 11, threaded rod 12 and other components to work with the baffle 8, the limit block 13 can be separated from the tensile gauge 9 by rotating the threaded rod 12, thus releasing the lock on the tensile gauge 9. At this time, the operator can replace the tensile gauge 9. The operation is simple and convenient, without the need to replace the entire testing device, which reduces the cost of use and makes it convenient for operators to use.

[0028] Example 2:

[0029] Please refer to Figures 1-5. A mounting base 14 is fixedly connected to the top right side of the base 1. An electric push rod 15 is fixedly connected to the top of the mounting base 14. A protective cover 16 is fixedly connected to the bottom of the electric push rod 15. The protective cover 16 is located directly above the mounting groove 3 and is made of transparent acrylic material. A notch 17 is provided on the left side of the protective cover 16.

[0030] Working principle: When the staff performs a tensile test on the O-ring, the staff can activate the electric push rod 15. The electric push rod 15 pushes the protective cover 16 down, thereby completely covering the pull hook 1 7, pull hook 2 10, mounting groove 3 and O-ring. The staff can observe the stretching of the O-ring through the protective cover 16. When the O-ring exceeds the tensile limit and breaks and splashes, it will be blocked by the protective cover 16 to avoid accidentally injuring the staff and facilitate use.

[0031] Compared with related technologies, the O-ring tensile testing device provided by this utility model has the following advantages: by setting up a protective cover 16 and a mounting groove 3, the protective cover 16 can completely cover the pull hook 1 7 and pull hook 2 10, and the staff can observe the internal situation through the protective cover 16. When the O-ring exceeds the tensile limit and breaks and splashes, it will be blocked by the protective cover 16 to avoid accidentally injuring the staff and making it easy to use.
