Description

Technical Field

[0001] This utility model relates to the field of bolt testing technology, specifically a screw corrosion resistance testing device. Background Technology

[0002] A bolt is a common mechanical part consisting of a head and a shank (a cylinder with external threads). It serves to connect and fasten parts by cooperating with a nut or by screwing it into parts with internal threads.

[0003] In the construction industry, bolts are widely used for connecting steel structures, such as bridges and factories, to firmly combine various types of steel and ensure the stability and safety of the structure. In the machinery manufacturing industry, bolts are key connecting parts for assembling various mechanical equipment. From simple small machines to complex large production line equipment, bolts are indispensable for tightly connecting and fixing various parts.

[0004] In corrosion resistance testing of bolts, the bolts are directly immersed in the testing solution. When it is necessary to retrieve the bolts during the test, the testing solution must be drained before they can be retrieved, which makes the bolt retrieval process quite cumbersome.

[0005] Therefore, a screw corrosion resistance testing device is proposed to address the above problems. Utility Model Content

Simultaneously, the placement boxes can place the screws in the middle of the solution, thereby increasing the contact with the solution. Subsequently, when observation is needed, the placement boxes can be pulled out by the handle for observation, thereby increasing the convenience of screw operation during testing.

[0008] Preferably, a second retaining plate is fixedly connected to the side wall of the placement box; multiple retaining slots are fixedly connected to the inner wall of the detection box; the retaining slots and the second retaining plate are correspondingly arranged and slidably engaged; by adding retaining slots, placement support can be provided for the placement box, so that when the screw is just retrieved, it can be placed through the retaining slots to drain the solution inside the placement box, thereby reducing the solution carried by the placement box after it leaves the solution.

[0009] Preferably, multiple damping spring shock absorbers are fixedly connected inside the partition; a fixing plate is fixedly connected to the top of each damping spring shock absorber; by adding damping spring shock absorbers, the lowering speed of the placement box can be slowed down when the placement box is placed into the solution, thereby reducing the impact between the fixing frame and the partition and reducing damage.

[0010] Preferably, multiple heating plates are fixed to the bottom of the detection box; the heating plates and the placement box are correspondingly arranged; by adding heating plates, the solution can be heated to accelerate the reaction rate of the screws and reduce corrosion, thereby reducing the detection time.

[0011] Preferably, a plurality of elastic plates are fixedly connected to the inner wall of the slot; the elastic plates and the slot are correspondingly arranged; by adding elastic plates, friction can be increased when the second card plate enters the slot, thereby increasing stability when supporting the placement box.

[0012] Preferably, a guide plate is fixedly connected to the top of the card slot; the guide plate and the card slot are correspondingly arranged; by adding the guide plate, the accuracy of the second card entering the card slot can be increased, thereby speeding up the entry of the second card into the card slot.

[0013] The advantages of this utility model are:

[0014] 1. The screw corrosion resistance testing device of this utility model uses a partition to divide the inside of the testing box into multiple sections, which can simultaneously test screws in different environments. At the same time, the placement box can place the screw in the middle of the solution to increase the contact with the solution. Then, when it is necessary to observe the screw, the placement box can be pulled out by the handle for observation, thereby increasing the convenience of screw operation during testing.

[0015] 2. The screw corrosion resistance testing device of this utility model can provide a placement support for the placement box by adding a slot, so that when the screw is just retrieved, it can be placed through the slot to drain the solution inside the placement box, thereby reducing the solution carried by the placement box after it leaves the solution.

[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 scope of protection of the present utility model.

[0024] Specific implementation examples are given below.

[0025] like Figures 1 to 5As shown in the embodiment of this utility model, a screw corrosion resistance testing device includes a testing box 1. Multiple partitions 11 are fixedly connected to the inner wall of the testing box 1. A fixing frame 12 is installed inside the testing box 1. Multiple placement boxes 13 are fixedly connected to the bottom of the fixing frame 12. The placement boxes 13 are located between the partitions 11 and the testing box 1. Multiple round holes 14 are opened at the bottom of the placement boxes 13. A first clamping plate 15 is fixedly connected to the side wall of the fixing frame 12. The first clamping plate 15 and the side wall of the testing box 1 are in sliding fit. A handle 16 is fixedly connected to the top of the first clamping plate 15. Multiple pipes 17 are opened at the bottom of the testing box 1. During operation, acidic, neutral, and alkaline solutions are poured into the multiple cavities between the partitions 11 in sequence. Then, multiple bolts are placed into the placement boxes 13 in sequence. Subsequently, the fixing frame 12 is aligned with the partitions 11 and placed into the testing box 1. As the placement boxes 13 gradually enter the testing box 1, they enter the cavities between the partitions 11 and come into contact with the solution. At this time, the solution passes through the round holes 14. 4. The screw enters the placement box 13 and comes into contact with it. After the placement box 13 enters the solution, the fixing bracket 12 needs to be pulled closer to the inner wall of the detection box 1, and then moved down to bring the first clamping plate 15 into contact with the detection box 1. After releasing the handle 16, the first clamping plate 15 will provide support for the placement box 13, so that the placement box 13 is located in the middle of the solution, thus suspending the screw in the middle of the solution. When it is necessary to remove the screw for observation, the handle 16 can be lifted and the placement box 13 can be pulled out of the solution to remove the screw for observation. If further testing is required, the placement box 13 can be put back into the solution. After the test is completed, the various solutions can be discharged through the pipe 17. By using the partition 11 to divide the inside of the detection box 1 into multiple sections, screws in different environments can be tested simultaneously. At the same time, the placement box 13 can place the screw in the middle of the solution, thereby increasing the contact with the solution. When it is necessary to observe it, the placement box 13 can be pulled out through the handle 16 for observation, thereby increasing the convenience of screw operation during the test.

[0026] like Figures 1 to 2 As shown, a second retaining plate 2 is fixedly connected to the side wall of the placement box 13; multiple retaining slots 21 are fixedly connected to the inner wall of the detection box 1; the retaining slots 21 and the second retaining plate 2 are correspondingly arranged and slidably engaged; during operation, when retrieving the screw, the second retaining plate 2 can be inserted into the retaining slot 21, so that the placement box 13 stays in the air, and then the solution inside the placement box 13 will gradually drip down to the bottom of the detection box 1 through the round hole 14, thereby draining the solution inside the placement box 13 and reducing the solution attached to the placement box 13; by adding the retaining slots 21, the placement box 13 can be provided with placement support, so that when the screw is just retrieved, it can be placed through the retaining slots 21 to drain the solution inside the placement box 13 and reduce the solution attached to the placement box 13 after it leaves the solution.

[0027] like Figure 3As shown, multiple damping spring shock absorbers 3 are fixedly connected inside the partition 11; a fixing plate 31 is fixedly connected to the top of the damping spring shock absorber 3; during operation, when the placement box 13 is placed inside the detection box 1, the fixing frame 12 will first contact the fixing plate 31. As the placement box 13 moves down, it will gradually compress the damping spring shock absorber 3. When the damping spring shock absorber 3 is compressed, the impact when the fixing frame 12 and the partition 11 come into contact will be reduced, thereby increasing the protection of the fixing frame 12 and the partition 11; by adding damping spring shock absorbers 3, the lowering speed of the placement box 13 can be slowed down when the placement box 13 is placed into the solution, thereby reducing the impact between the fixing frame 12 and the partition 11 and reducing damage.

[0028] like Figure 2 As shown, multiple heating plates 4 are fixed to the bottom of the detection box 1; the heating plates 4 and the placement box 13 are arranged correspondingly; during operation, after the screw is placed into the solution using the placement box 13, the heating plates 4 can be activated to heat the solution, which will accelerate the corrosion of the screw and thus speed up the detection speed; by adding heating plates 4, the solution can be heated to accelerate the reaction rate with the screw and cause it to corrode, thereby reducing the detection time.

[0029] like Figure 5 As shown, multiple elastic plates 5 are fixed to the inner wall of the slot 21; the elastic plates 5 and the slot 21 are correspondingly arranged; during operation, when the second card 2 is inserted into the second card 2, the elastic plates 5 are squeezed, thereby pushing the elastic plates 5 to both sides. When pushing the elastic plates 5, the elastic plates 5 will stick tightly to the surface of the second card 2, thereby increasing the contact between the slot 21 and the second card 2; by adding the elastic plates 5, the friction when the second card 2 enters the slot 21 can be increased, thereby increasing the stability when supporting the placement box 13.

[0030] like Figure 5 As shown, a guide plate 6 is fixedly connected to the top of the slot 21; the guide plate 6 and the slot 21 are correspondingly arranged; during operation, when the second card 2 is inserted into the slot 21, the bottom of the second card 2 can be placed on the surface of the guide plate 6 first, and then slide down the surface of the guide plate 6 to move into the slot 21; by adding the guide plate 6, the accuracy of the second card 2 entering the slot 21 can be increased, thereby speeding up the speed at which the second card 2 enters the slot 21.

[0031] Working principle: First, acidic, neutral, and alkaline solutions are poured sequentially into the multiple cavities between the partitions 11. Then, multiple bolts are inserted into the placement box 13. Next, the fixing bracket 12 is aligned with the partitions 11 and placed into the detection box 1. As the placement box 13 gradually enters the detection box 1, it enters the cavities between the partitions 11 and comes into contact with the solution. At this time, the solution enters the placement box 13 through the round hole 14, thus contacting the screws. After the placement box 13 enters the solution, the fixing bracket 12 needs to be pulled closer to the inner wall of the detection box 1, and then continues to move downwards... When the first clamping plate 15 contacts the detection box 1, and then the handle 16 is released, the first clamping plate 15 will provide support for the placement box 13, placing the placement box 13 in the middle of the solution, thus suspending the screw in the middle of the solution. When it is necessary to remove the screw for observation, the handle 16 can be lifted and the placement box 13 can be pulled out of the solution to remove the screw for observation. If further testing is required, the placement box 13 can be put back into the solution. After the test is completed, all solutions can be drained through the pipe 17. When retrieving the screw, the second clamping plate 2 can be inserted into the clamping slot 21 to keep the placement box 13 in place. In the air, the solution inside the placement box 13 will gradually drip through the round hole 14 to the bottom of the detection box 1, thereby draining the solution inside the placement box 13 and reducing the amount of solution attached to the placement box 13. When the placement box 13 is placed inside the detection box 1, the fixing frame 12 will first contact the fixing plate 31. As the placement box 13 moves downward, it will gradually compress the damping spring shock absorber 3. When the damping spring shock absorber 3 is compressed, the impact when the fixing frame 12 and the partition plate 11 come into contact will be reduced, thereby increasing the protection of the fixing frame 12 and the partition plate 11. When using the placement box 13 to place the screw After the nail is placed inside the solution, the heating plate 4 can be activated to heat the solution. At this time, the solution will accelerate the corrosion of the screw, thereby speeding up the detection speed. When the second card plate 2 is inserted into the second card plate 2, the elastic plate 5 will be squeezed, thereby pushing the elastic plate 5 to both sides. When pushing the elastic plate 5, the elastic plate 5 will be in close contact with the surface of the second card plate 2, thereby increasing the contact between the card slot 21 and the second card plate 2. When the second card plate 2 is inserted into the card slot 21, the bottom of the second card plate 2 can be placed on the surface of the guide plate 6 first, and then slide down through the surface of the guide plate 6 to move into the card slot 21.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
