Description

Technical Field

[0001] The utility model relates to the technical field of experimental equipment, in particular to a salt spray test round tube storage rack. Background Art

[0002] The salt spray test chamber is one of the artificial climate environment "three-proof" (humid heat, salt spray, and mold) test equipment. It simulates the dispersion system composed of tiny salt droplets in the atmosphere. It is widely used to conduct salt spray corrosion tests on electronic, electrical, automotive, motorcycle, hardware and other products, parts, and metal materials and products such as plating and coating.

[0003] The salt spray test standard (GB / T 10125-2021) generally requires that the test surface of the sample be at a certain angle to the vertical direction. The content of the test specimen placement in the test standard (GB / T 10125-2021) is as follows:

[0004] 1. The test specimen should not be placed in a position where it is directly sprayed with salt mist.

[0005] 2. The placement angle of the test specimen surface in the salt spray chamber is very important. In principle, the test specimen is a flat plate, and the test surface is placed at an angle of 15° to 25° to the vertical in the salt spray chamber, preferably 20°. For irregular test specimens, such as entire workpieces, the above requirements should also be met as closely as possible.

[0006] The most common salt spray testers on the market are equipped with a V-shaped sample rack and a PVC round rod. During the test, the test sample only needs to be placed on the V-shaped sample rack and leaned against the PVC round rod. The test surface of the sample can be at a 20° angle to the vertical direction, meeting the test standard requirements.

[0007] When the test sample is a steel plate, it can be placed in the salt spray test chamber very conveniently and stably. However, when the test sample is a round steel tube, the contact area between the arc surface of the round tube and the V-shaped sample holder and the PVC round rod is small, which makes it easy to place it unstable. Moreover, the position of the V-shaped sample holder and the PVC round rod is fixed and cannot be adjusted. Therefore, when the round steel tube sample is long, the bottom of the round steel tube sample is placed in the V-shaped sample groove and the round steel tube body is tilted on the PVC round rod. Its center of gravity is above the contact point between the test sample and the PVC round rod, resulting in the test sample being unstable. Each time the test is carried out, the operator needs to waste a lot of time to place the sample, resulting in low test efficiency. Moreover, as the test progresses, the angle of the test sample may gradually shift or even collapse, resulting in the inability to effectively implement the angle required by the standard, which directly affects the accuracy and rigor of the test of such samples. In addition, the ordinary salt spray test stand has a single structure and can only test a certain type of sample. It has certain limitations. When the type of sample changes or the number is large, it cannot be freely adjusted, which brings certain troubles to the salt spray test. Therefore, it is necessary to further improve the existing salt spray test sample placement rack. Utility Model Content

[0008] In response to the shortcomings of the existing technology, the utility model proposes a salt spray test round tube storage rack, which not only allows samples of different lengths to be placed conveniently, quickly and firmly to meet the requirements of salt spray tests for various samples, but also can promptly drain the salt spray water in the supporting groove to avoid unnecessary damage to the product.

[0009] To achieve the above technical solution, the utility model provides a salt spray test circular tube storage rack, comprising: two triangular side panels arranged in parallel and at intervals, the tops of the two triangular side panels are connected by strips, and the bottoms of the two triangular side panels are connected by two V-shaped supporting grooves arranged in parallel and at intervals, each triangular side panel is provided with two long holes distributed in an "eight" shape, a scale is provided on one side of each long hole, a slider is installed in each long hole, and a round rod is installed between the corresponding sliders on the two triangular side panels.

[0010] In the above technical solution, during actual operation, the slider can be adjusted up and down according to the length of the test sample, ensuring that the contact point between the round rod and the test sample is above the sample's center of gravity and that the surface of the test sample is at a 20° angle to the vertical. This ensures that the test sample is firmly placed, preventing it from tilting or falling during the test, while also meeting the angle requirements of the salt spray test specification. The triangular side panels are scaled on one side of the elongated hole. When the height of the round rod needs to be adjusted during the test, the sliders on both sides can be quickly and accurately adjusted to the same height to ensure the round rod is level and save test time.

[0011] Preferably, the slider is locked in the elongated hole by a PP bolt and a nut. In actual use, the position of the slider in the elongated hole can be adjusted by screwing the PP bolt and the nut to meet the requirements of different experiments.

[0012] Preferably, a U-shaped groove is provided on the top of the slider, and the round rod is placed in the U-shaped groove to achieve rapid limited installation of the round rod.

[0013] Preferably, the V-shaped supporting groove is formed by welding two PP plates at 90 degrees, and drainage holes are evenly arranged on the bottom of the V-shaped supporting groove to ensure that salt spray droplets can be quickly drained away and do not accumulate in the groove.

[0014] Preferably, the triangular side panels and slats are both made of PP boards, which are light in weight, high in strength and easy to process.

[0015] Preferably, the round rod is made of PVC material. PVC material has good acid and alkali resistance and weather resistance, and high strength, and is suitable for making the round rod of the salt spray test round tube storage rack.

[0016] The beneficial effects of the salt spray test round tube storage rack provided by the utility model are:

[0017] (1) This salt spray test round tube storage rack has a simple structure, reasonable design, small footprint, low cost, and is convenient and practical. During actual operation, the slider can be adjusted up and down according to the length of the test sample, so as to ensure that the contact point between the round rod and the test sample is above the center of gravity of the sample, and the surface of the test sample is 20° to the vertical direction; this can not only ensure that the test sample is placed firmly and will not deflect or fall during the test, but also meet the angle requirements within the salt spray test specifications. The triangular side plate is set with a scale on one side of the long hole. When the test needs to adjust the height of the round rod, the sliders on both sides can be quickly and accurately adjusted to the same height to ensure that the round rod is level and save test time.

[0018] (2) This salt spray test round tube storage rack does not require any modification to the original salt spray test chamber when used, and can be directly placed in the salt spray test chamber; when use is completed, it can be taken out at any time without affecting the original test function of the salt spray test chamber, and is very flexible and convenient to use.

[0019] (3) The salt spray test circular tube storage rack is bilaterally symmetrical, and samples of different shapes can be placed on the V-shaped supporting grooves on both sides of the salt spray test circular steel tube sample storage rack at the same time, thereby increasing the number of samples that can be tested simultaneously in the salt spray test, improving the test efficiency, and saving experimental costs and time.

[0022] The following is a clear and complete description of the technical solutions in the embodiments of the present invention, in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary persons in this field without creative work are within the scope of protection of the present invention.

[0023] Embodiment: A salt spray test round tube storage rack.

[0024] Reference Figure 1 As shown, a salt spray test circular tube storage rack comprises: two parallel, spaced-apart triangular side panels 1, connected at their tops by a slat 2. Both the triangular side panels 1 and the slat 2 are made of PP sheet, which is lightweight, strong, and easy to process. The bottoms of the two triangular side panels 1 are connected by two parallel, spaced-apart V-shaped support grooves 4, forming a stable rack structure.

[0025] Each triangular side panel 1 is provided with two elongated holes 11 distributed in an "eight" shape, and a slider 5 is installed on the elongated hole 11. The slider 5 is locked in the elongated hole 11 by a PP bolt and a nut 6 to form a movable locking structure. In actual use, the position of the slider 5 in the elongated hole 11 can be adjusted by screwing the PP bolt and the nut 6 to meet the requirements of different experiments.

[0026] Each elongated hole 11 is provided with a scale 12 on one side. When the height of the round rod needs to be adjusted during testing, the sliders on both sides can be quickly and accurately adjusted to the same height to ensure the round rod is level and save testing time. The top of the slider 5 is provided with a U-shaped groove. The round rod 3 is installed between the corresponding sliders 5 on the two triangular side panels 1. The round rod 3 is placed in the U-shaped groove to achieve quick and limited installation of the round rod 3. The round rod 3 is made of PVC material. PVC has excellent acid and alkali resistance and weather resistance, and is also high in strength, making it suitable for making the round rod 3 of the salt spray test round tube storage rack.

[0027] In this embodiment, the V-shaped supporting groove 4 is formed by welding two PP plates at 90 degrees. Drain holes 41 are evenly arranged at the bottom of the V-shaped supporting groove 4 to ensure that salt spray droplets can be quickly drained away and not accumulated in the groove.

[0028] This salt spray test circular tube storage rack features a simple structure, rational design, minimal footprint, low cost, and practical convenience. During operation, the slider 5 can be adjusted up and down according to the length of the test sample, ensuring that the contact point between the round rod 3 and the test sample is above the sample's center of gravity and that the surface of the test sample is at a 20° angle to the vertical. This ensures that the test sample is securely placed, preventing it from tilting or falling during the test, while also meeting the angle requirements of the salt spray test specification. This allows for convenient and quick placement of samples of varying lengths, meeting the requirements of various salt spray test conditions, and allows for the timely drainage of salt spray water from the support trough, preventing unnecessary damage to the product.

[0029] This salt spray test round tube rack requires no modifications to the existing salt spray test chamber and can be placed directly inside it. When finished, it can be removed at any time without affecting the chamber's original testing functions, making it extremely flexible and convenient to use. Furthermore, this salt spray test round tube rack is bilaterally symmetrical, allowing for simultaneous placement of samples of varying shapes in the V-shaped support grooves (4) on either side of the rack. This increases the number of samples that can be simultaneously tested in salt spray tests, improves testing efficiency, and saves experimental costs and time.

[0030] The above description is only a preferred embodiment of the present invention, but the present invention should not be limited to the contents disclosed in the embodiment and the drawings. Therefore, any equivalent or modification completed without departing from the spirit disclosed in the present invention shall fall within the scope of protection of the present invention.
