Description

Technical Field

[0001] This utility model relates to the field of corrosion testing technology, and in particular to a new material corrosion testing device. Background Technology

[0002] Existing corrosion testing equipment mainly consists of salt spray test chambers and damp heat test chambers. Their basic working principle is to place the sample in a sealed chamber and accelerate the corrosion process of the material by simulating a corrosive environment (such as salt spray, high temperature and high humidity). However, existing equipment has significant shortcomings in sample clamping: most equipment uses bolt clamping or simple clamps for fixing, which is cumbersome to operate and the clamping force is not easy to control, which may cause damage to the sample surface coating or unstable clamping, affecting the accuracy of the test results. In addition, traditional clamps are difficult to adapt to samples of different shapes and sizes, with poor versatility. Each time a sample is changed, a lot of time is required for adjustment, resulting in low testing efficiency. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies where most devices are fixed using bolt clamping or simple clamps, which are cumbersome to operate and difficult to control, potentially causing damage to the sample surface coating or unstable clamping, thus affecting the accuracy of test results. This invention provides a new material corrosion testing device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a new material corrosion testing device, comprising a testing box, a support frame fixedly connected to the outer surface of the testing box, a base plate at the bottom of the support frame, a fixed clamping plate fixedly connected to the outer surface of the base plate, a sliding rod fixedly connected to the inner wall of the base plate, a connecting rod sleeved on the outer surface of the sliding rod, a movable clamping plate fixedly connected to the outer surface of the connecting rod, a pull plate provided on the outer surface of the base plate, a limiting rod fixedly connected to the outer surface of the pull plate, the limiting rod slidably connected to the base plate, a pressing block fixedly connected to the outer surface of the limiting rod, a rotating rod fixedly connected to the inner wall of the connecting rod, a roller sleeved on the outer surface of the rotating rod, and the roller rotatably connected to the rotating rod.

[0005] In a preferred embodiment, a motor is fixedly connected to the outer surface of the support frame, a lead screw is fixedly connected to the output end of the motor, a movable plate is sleeved on the outer surface of the lead screw, and the movable plate is threadedly connected to the lead screw.

[0006] In a preferred embodiment, a movable rod is fixedly connected to the outer surface of the movable plate, the movable rod is slidably connected to the support frame, and the movable rod is fixedly connected to the base plate.

[0007] In a preferred embodiment, a second spring is sleeved on the outer surface of the slide rod, one end of the second spring is fixedly connected to the inner wall of the base plate, and the other end of the second spring is fixedly connected to one end of the connecting rod.

[0008] In a preferred embodiment, a first spring is sleeved on the outer surface of the limiting rod, one end of the first spring is fixedly connected to one side of the extrusion block, and the other end of the first spring is fixedly connected to the inner wall of the base plate.

[0009] In a preferred embodiment, the outer surface of the connecting rod is provided with a sliding hole that matches the slide rod, and the sliding hole is slidably connected to the connecting rod.

[0010] In a preferred embodiment, the outer surface of the base plate is provided with a sliding groove adapted to the connecting rod, and the sliding groove is slidably connected to the connecting rod.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] This invention utilizes a pull plate to move a limiting rod within a base plate. The movement of the limiting rod causes the pressing block to move, compressing the first spring and releasing the pressure on the roller. The reset of the second spring then causes the connecting rod to slide along the slide bar, moving the movable clamping plate. This allows workers to easily place carbon steel between the fixed and movable clamping plates. Releasing the pull plate causes the first spring to return, resetting the pressing block and causing it to press the roller, which then rotates around the rotating rod and presses the connecting rod. This re-presses the second spring, causing the movable clamping plate to clamp the carbon steel. Attached Figure Description

[0019] 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.

[0020] Example 1

[0021] like Figures 1-4 As shown, this utility model provides a technical solution: a new material corrosion testing device, including a testing box 1, a support frame 2 fixedly connected to the outer surface of the testing box 1, a bottom plate 7 at the bottom of the support frame 2, a fixing clamp 9 fixedly connected to the outer surface of the bottom plate 7, a sliding rod 8 fixedly connected to the inner wall of the bottom plate 7, a connecting rod 10 sleeved on the outer surface of the sliding rod 8, a sliding hole adapted to the sliding rod 8 on the outer surface of the connecting rod 10, the sliding hole slidably connected to the connecting rod 10, a sliding groove adapted to the connecting rod 10 on the outer surface of the bottom plate 7, the sliding groove slidably connected to the connecting rod 10, a movable clamp 11 fixedly connected to the outer surface of the connecting rod 10, and a pull plate 12 on the outer surface of the bottom plate 7. A limiting rod 13 is fixedly connected to the outer surface of the pull plate 12. The limiting rod 13 is slidably connected to the base plate 7. A pressing block 14 is fixedly connected to the outer surface of the limiting rod 13. A first spring 15 is sleeved on the outer surface of the limiting rod 13. One end of the first spring 15 is fixedly connected to one side of the pressing block 14. The other end of the first spring 15 is fixedly connected to the inner wall of the base plate 7. A rotating rod 16 is fixedly connected to the inner wall of the connecting rod 10. A roller 17 is sleeved on the outer surface of the rotating rod 16. The roller 17 is rotatably connected to the rotating rod 16. A second spring 18 is sleeved on the outer surface of the slide rod 8. One end of the second spring 18 is fixedly connected to the inner wall of the base plate 7. The other end of the second spring 18 is fixedly connected to one end of the connecting rod 10.

[0022] In this embodiment, the detection box 1 ensures the normal operation of the detection work, the support frame 2 provides support for other components, and the base plate 7 provides an installation environment for other components. When performing corrosion testing on carbon steel, pulling the pull plate 12 causes the limiting rod 13 to slide inside the base plate 7. The movement of the limiting rod 13 causes the pressing block 14 to move, which in turn compresses the first spring 15, putting the first spring 15 into a compressed state. This releases the pressure of the pressing block 14 on the roller 17, and then the second spring 18... The connecting rod 10 slides along the slide bar 8, thereby moving the movable clamping plate 11. This allows the worker to place the carbon steel between the fixed clamping plate 9 and the movable clamping plate 11. Then, by releasing the pull plate 12, the first spring 15 rebounds, causing the pressing block 14 to reset. The pressing block 14 then presses the roller 17, causing the roller 17 to rotate around the rotating rod 16 and press the connecting rod 10. This re-presses the second spring 18, causing the movable clamping plate 11 to clamp the carbon steel, ensuring that the carbon steel will not fall off during the inspection process.

[0023] Example 2

[0024] like Figures 1-4 As shown, a motor 3 is fixedly connected to the outer surface of the support frame 2, a lead screw 4 is fixedly connected to the output end of the motor 3, a movable plate 5 is sleeved on the outer surface of the lead screw 4, the movable plate 5 is threadedly connected to the lead screw 4, a movable rod 6 is fixedly connected to the outer surface of the movable plate 5, the movable rod 6 is slidably connected to the support frame 2, and the movable rod 6 is fixedly connected to the base plate 7.

[0025] In this embodiment, after the carbon steel is fixed, the motor 3 drives the lead screw 4 to rotate inside the bearing. Since the lead screw 4 is threadedly connected to the moving plate 5, the moving plate 5 moves up and down while the lead screw 4 rotates. The movement of the moving plate 5 drives the moving rod 6 to move, thereby driving the base plate 7 to move. The movement of the base plate 7 drives the carbon steel to descend into the detection box 1, thereby performing corrosion detection on the carbon steel.

[0026] Working principle:

[0027] like Figures 1-4As shown, in this utility model, when performing a corrosion test on carbon steel, pulling the pull plate 12 causes the limiting rod 13 to slide inside the base plate 7. The movement of the limiting rod 13 causes the pressing block 14 to move, which in turn compresses the first spring 15, putting the first spring 15 into a compressed state. This releases the pressure of the pressing block 14 on the roller 17. Then, the reset of the second spring 18 causes the connecting rod 10 to slide along the slide bar 8, thereby moving the movable clamping plate 11. This facilitates the placement of the carbon steel between the fixed clamping plate 9 and the movable clamping plate 11. Finally, releasing the pull plate 12 causes the first spring 15 to rebound, causing the pressing block 14 to reset. The pressing block 14 presses against the roller 17, causing the roller 17 to rotate around the rotating rod 16 and press against the connecting rod 10, which in turn presses against the second spring 18. This causes the movable clamping plate 11 to clamp the carbon steel, ensuring that the carbon steel will not fall off during the testing process. After the carbon steel is fixed, the motor 3 drives the lead screw 4 to rotate inside the bearing. Since the lead screw 4 is threadedly connected to the moving plate 5, the rotation of the lead screw 4 drives the moving plate 5 to move up and down. The movement of the moving plate 5 drives the moving rod 6 to move, which in turn drives the base plate 7 to move. The movement of the base plate 7 causes the carbon steel to descend into the testing box 1, thus performing corrosion testing on the carbon steel.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
