Abstract

This utility model relates to the field of salt spray corrosion testing technology and discloses a walk-in composite salt spray testing device, including a housing, an installation box fixedly connected inside the housing, an atomizing nozzle fixedly connected to the rear end of the housing, and a brine tank fixedly connected to the rear end of the housing. The brine tank and the atomizing nozzle are fixedly connected via a connecting pipe. This utility model places the product to be tested on a support assembly, then activates a drive assembly to move a lifting assembly. The movement of the lifting assembly not only moves the product on the support assembly upwards but also allows for angle adjustment. The atomizing nozzle draws brine from the brine tank through the connecting pipe and atomizes and sprays it, uniformly spraying the salt spray onto the product surface, completing a comprehensive salt spray corrosion test. This solves the problem that existing walk-in salt spray corrosion testing devices cannot spray salt spray from all directions, resulting in limited comprehensiveness and accuracy of test results and an inability to fully simulate the corrosion conditions of the product in its actual use environment.

Description

Technical Field

[0001] This utility model relates to the field of salt spray corrosion testing technology, and in particular to a walk-in composite salt spray testing device. Background Technology

[0002] Salt spray testing is an environmental testing method widely used to assess the corrosion resistance of products or metallic materials. It mainly uses salt spray testing equipment to create artificially simulated salt spray environmental conditions to assess the product's salt spray corrosion resistance. Salt spray testing is generally divided into two categories: natural environment exposure testing and artificial accelerated simulated salt spray environment testing. Among them, artificial accelerated simulated salt spray environment testing uses a test device with a certain volume space—a salt spray test chamber—to artificially create a salt spray environment inside the chamber, thereby achieving rapid and efficient assessment of the product's salt spray corrosion resistance.

[0003] In actual product salt spray corrosion testing, walk-in salt spray corrosion testing equipment is usually required to conduct comprehensive salt spray corrosion tests on the product. However, the existing walk-in salt spray corrosion testing equipment on the market has certain limitations. Specifically, most of these devices do not have the function of spraying salt spray liquid from all directions; they can only spray salt spray liquid onto the product from a fixed angle. This design cannot meet the needs of comprehensive salt spray corrosion testing, which limits the comprehensiveness and accuracy of the test results. Consequently, it reduces the overall test effect of the salt spray corrosion testing equipment, fails to fully simulate the corrosion situation of the product in the actual use environment, and affects the accurate assessment of the product's corrosion resistance. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides a walk-in composite salt spray test device to solve the problem that the existing walk-in salt spray corrosion test device cannot spray salt spray liquid in all directions, resulting in limited comprehensiveness and accuracy of test results and failure to fully simulate the corrosion conditions of the actual use environment of the product.

[0005] This utility model provides a walk-in composite salt spray testing device, comprising a housing, an installation box fixedly connected inside the housing, an atomizing nozzle fixedly connected to the rear end of the housing, a salt water tank fixedly connected to the rear end of the housing, and a connecting pipe connecting the salt water tank and the atomizing nozzle. A lifting assembly is provided inside the installation box, and a support assembly is provided at the upper end of the lifting assembly for placing the product to be tested. The device also includes:

[0006] A drive assembly is installed at the lower end inside the mounting box. The drive assembly is used to drive the lifting assembly to raise or lower the lifting assembly.

[0007] Preferably, the lifting assembly includes a threaded rod and a lifting plate. The threaded rod is rotatably connected inside the mounting box, and the lifting plate is threadedly connected to the side wall of the threaded rod. A limit post is fixedly connected inside the mounting box, and the limit post passes through the lifting plate and is slidably connected thereto. A rising rod is fixedly connected to the upper end of the lifting plate, and the upper end of the rising rod passes through the outer wall of the mounting box and is slidably connected thereto.

[0008] Preferably, the support assembly includes a support ring and a rotating plate. The support ring is fixedly connected to the upper end of the rising rod, the rotating plate is rotatably connected to the inner wall of the support ring, a support plate is fixedly connected to the upper end of the rotating plate, and inserts are fixedly connected to the upper end of the support plate at equal intervals.

[0009] Preferably, the upper end face of the threaded rod is provided with a sliding hole, the sliding hole is configured as a rectangular hole, and a transmission rod is slidably connected inside the sliding hole, the upper end of the transmission rod being fixedly connected to the lower end of the rotating plate.

[0010] Preferably, the drive assembly includes a motor and a second gear. The motor is fixedly connected to the lower end inside the mounting box. A first gear is fixedly connected to the output shaft end of the motor. The second gear is fixedly connected to the lower side wall of the threaded rod. The first gear and the second gear mesh with each other.

[0011] Preferably, the front end of the box is rotatably connected to a box door via a hinge, and a handle is fixedly connected to the front end of the box door.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model, through the coordinated arrangement of a threaded rod, sliding hole, lifting plate, limiting post, rising rod, transmission rod, support ring, rotating plate, support plate, and insert post, enables the product under test to achieve multi-angle lifting and rotation within the chamber. Combined with the atomizing nozzle, it ensures that the salt spray liquid can be sprayed to all parts of the product from all directions, thus overcoming the limitation of existing technologies that can only spray salt spray liquid from a fixed angle. This all-round spraying function can more realistically simulate the corrosion conditions that the product may face in actual use environments, significantly improving the comprehensiveness and accuracy of salt spray corrosion tests, and providing a more reliable basis for evaluating the corrosion resistance performance of products.

[0014] 2. This utility model achieves automatic control of the lifting component through motor and gear transmission, which can easily adjust the position and angle of the product inside the chamber. At the same time, the chamber door facilitates the operator to quickly place and take out the product to be tested, further improving the ease of use of the testing device. This improvement in automation and convenience not only increases the testing efficiency but also reduces the error of manual operation, further ensuring the reliability of the test results.

Detailed Implementation

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. In this specification, "multiple" refers to two or more.

[0024] In the description of this specification, references to terms such as "embodiment," "one embodiment," and "one implementation" indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or implementation is included in at least one embodiment or illustrative embodiment of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or implementation. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or implementations.

[0025] Example 1: Please refer to the accompanying drawings. This invention provides a technical solution:

[0026] A walk-in composite salt spray test device, such as Figures 1-3 As shown, the device includes a housing 1, an installation box 2 fixedly connected inside the housing 1, an atomizing nozzle 6 fixedly connected to the rear end of the housing 1, a saline tank 7 fixedly connected to the rear end of the housing 1, and the saline tank 7 and the atomizing nozzle 6 fixedly connected by a connecting pipe. A lifting assembly 3 is installed inside the installation box 2, and a support assembly 4 is installed at the upper end of the lifting assembly 3. The support assembly 4 is used to place the product to be tested. It also includes:

[0027] Drive component 5 is installed at the lower end inside the mounting box 2. Drive component 5 is used to drive the lifting component 3 to raise or lower the lifting component.

[0028] In practical use, the product to be tested is first placed on the support component 4, and then the drive component 5 is activated to drive the lifting component 3. The operation of the lifting component 3 not only moves the product on the support component 4 upward, but also allows for the adjustment of the product's angle. The atomizing nozzle 6 draws salt water from the salt water tank 7 through the connecting pipe and sprays it atomized. The salt spray is evenly sprayed on the product surface, completing the all-round salt spray corrosion test. This solves the problem that the existing walk-in salt spray corrosion test device cannot spray salt spray in all directions, resulting in limited comprehensiveness and accuracy of the test results and the inability to fully simulate the corrosion conditions of the product in the actual use environment.

[0029] like Figure 3 As shown, the lifting assembly 3 includes a threaded rod 31 and a lifting plate 32. The threaded rod 31 is rotatably connected inside the mounting box 2. The lifting plate 32 is threadedly connected to the side wall of the threaded rod 31. A limit post 33 is fixedly connected inside the mounting box 2. The limit post 33 passes through the lifting plate 32 and is slidably connected to it. A rising rod 34 is fixedly connected to the upper end of the lifting plate 32. The upper end of the rising rod 34 passes through the outer wall of the mounting box 2 and is slidably connected to it.

[0030] Support assembly 4 includes a support ring 41 and a rotating plate 42. The support ring 41 is fixedly connected to the upper end of the rising rod 34, and the rotating plate 42 is rotatably connected to the inner wall of the support ring 41. A support plate 43 is fixedly connected to the upper end of the rotating plate 42, and inserts 44 are fixedly connected to the upper end of the support plate 43 at equal intervals.

[0031] A sliding hole 311 is provided on the upper end face of the threaded rod 31. The sliding hole 311 is a rectangular hole. A transmission rod 35 is slidably connected inside the sliding hole 311. The upper end of the transmission rod 35 is fixedly connected to the lower end of the rotating plate 42.

[0032] When the drive assembly 5 is started, it drives the threaded rod 31 to rotate. Since the lifting plate 32 is threadedly connected to the threaded rod 31 and the lifting plate 32 is limited by the limiting post 33, the lifting plate 32 can only move up and down along the limiting post 33. The up and down movement of the lifting plate 32 drives the rising rod 34 to rise or fall, thereby adjusting the height of the support assembly 4. At the same time, the transmission rod 35 slides in the rectangular sliding hole 311 at the upper end of the threaded rod 31. The rotation of the threaded rod 31 can drive the transmission rod 35, thereby driving the rotating plate 42 to rotate around the support ring 41, thereby realizing the angle adjustment of the support plate 43. The product to be tested is placed on the support plate 43 and fixed by the insertion post 44 to ensure the stability of the product during the test. With this setting, the test device can realize the height and angle adjustment of the product. Combined with the all-round spray function of the atomizing nozzle 6, it further improves the effect and reliability of the salt spray corrosion test.

[0033] Example 2: The structure of this example is basically the same as that of Example 1, except that, as shown in the figure... Figure 4 , Figure 5 As shown, the drive assembly 5 includes a motor 51 and a second gear 53. The motor 51 is fixedly connected to the lower end inside the mounting box 2. The output shaft end of the motor 51 is fixedly connected to a first gear 52. The second gear 53 is fixedly connected to the lower side wall of the threaded rod 31. The first gear 52 and the second gear 53 mesh with each other.

[0034] The front end of the box 1 is connected to the box door 11 via a hinge, and the front end of the box door 11 is fixedly connected to the handle 12.

[0035] The motor 51 serves as the core power source for the drive assembly 5, driving the first gear 52 to rotate via the output shaft. Since the first gear 52 meshes with the second gear 53, the rotation of the first gear 52 drives the second gear 53 to rotate synchronously, thereby driving the threaded rod 31 to rotate. The rotation of the threaded rod 31, through its threaded connection with the lifting plate 32, enables the lifting plate 32 to move up and down, thereby driving the lifting rod 34 and the support assembly 4 to rise or fall as a whole to meet the testing requirements at different heights. At the same time, the door 11 at the front of the housing 1 is connected by a hinge, making it convenient for operators to open and close the housing 1. The handle 12 design makes it easy for operators to operate the door 11, further improving the ease of use of the testing device. This not only realizes the height adjustment function of the product, but also improves the operational convenience and safety of the device through the setting of the door 11 and the handle 12.

[0036] Although the disclosure is as stated above, the scope of protection of this disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this utility model.
