Description

Technical Field

[0001] This utility model relates to the field of salt spray detection technology, and in particular to a salt spray test detection device. Background Technology

[0002] Salt spray testing equipment uses salt spray corrosion to test the reliability of the tested samples. Salt spray refers to a diffuse system composed of tiny salt-containing droplets in the atmosphere. It is one of the artificial environmental three-proof series and is mainly used to test the corrosion resistance of various metal materials and products after surface treatments such as painting, coating, electroplating, anodic film, or rust prevention. It is a test device that simulates the natural environment and actual conditions to effectively resist and understand corrosion. The salt spray testing equipment places the items to be tested inside the test chamber, closes the chamber lid, and performs the test.

[0003] There is often a gap between the outer cover of the salt spray test device and the test chamber, which can easily cause gas inside the test chamber to leak from the cover, affecting the test. Such salt spray test devices have poor sealing performance and are prone to leakage, which affects the test.

[0004] Existing patent (publication number: CN219348590U) discloses a powder salt spray test detection device. This utility model relates to the field of salt spray detection technology and discloses a powder salt spray test detection device that solves the problem of poor sealing effect and easy leakage in current salt spray test detection devices, which affects the test. It includes a test chamber, and a protective cover is rotatably connected to one side of the upper end of the test chamber. A groove is opened at the upper end of the test chamber. In this utility model, when the protective cover moves, it drives the sealing plate to move, so that the sealing ring is located inside the groove. The top wall of the inner wall of the sealing groove contacts the upper end of the test chamber. Pushing the limiting plate upward, the round rod drives the locking block to move through the locking groove to the position above the fixed plate. Rotating the limiting plate to one side, the lower end of the locking block contacts the upper end of the fixed plate. Under the elastic potential energy of the spring, the sealing plate and the upper end of the test chamber are connected more tightly. With the double sealing and tightness of the sealing components, the sealing effect between the protective cover and the test chamber is better, avoiding the existence of gaps between the protective cover and the test chamber, which would affect the use of the test chamber.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, each operation of the protective cover and the testing box, as well as the sealing structure, requires multiple complex manual steps, such as pushing and rotating the limiting plate. This increases the user's workload and time cost. Furthermore, the cumbersome manual operation prolongs the single testing cycle, thereby reducing overall production efficiency.

[0006] Therefore, a salt spray test detection device is proposed. Utility Model Content

[0007] The purpose of this utility model is to provide a salt spray test detection device that can solve the problem that in the above-mentioned patent, the connection between the protective cover and the test box and the sealing structure need to be manually performed in multiple complicated steps, such as pushing the limit plate and rotating the limit plate, each time. This increases the user's operating burden and time cost. In addition, the cumbersome manual operation will prolong the single test cycle, thereby reducing the overall production efficiency.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a salt spray test detection device, including a test chamber, a protective cover is provided on the top of the test chamber, the bottom of the rear side of the protective cover is rotatably connected to the top of the rear side of the test chamber, an automatic opening mechanism is provided on both sides of the test chamber and the protective cover, a sealing component is provided between the test chamber and the protective cover, and a sealing structure is provided on the front side of the test chamber and the protective cover.

[0009] The automatic opening mechanism includes fixed sleeves bolted to both sides of the testing box. An electric push rod is rotatably connected inside the fixed sleeve. Fixed shafts are fixedly connected to both sides of the protective cover. A rotating ball is fixedly connected to the telescopic end of the electric push rod, and the rotating ball is rotatably connected to the outside of the fixed shaft.

[0010] Preferably, the sealing assembly includes a sealing groove formed on the top of the testing chamber, and an adhesive piece is provided on the bottom side inside the sealing groove.

[0011] Preferably, a sealing gasket is bolted to the bottom of the protective cover, the sealing gasket is snapped into the inside of the sealing groove, and the bottom of the sealing gasket contacts the top of the adhesive piece.

[0012] Preferably, a sealing gasket is fixedly connected to the inner side of the sealing gasket, the bottom of the sealing gasket is in contact with the inner side of the top of the test box, and the sealing gasket is located inside the sealing groove.

[0013] Preferably, the sealing structure includes a fixing plate bolted to the top front side of the test box, and the top of the fixing plate has a positioning hole.

[0014] Preferably, a connecting plate is fixedly connected to the front side of the protective cover, and a positioning post is fixedly connected to the bottom of the connecting plate, with the positioning post engaging inside the positioning hole.

[0015] Preferably, a control console is bolted to the right side of the detection box, and the control console is electrically connected to the electric push rod.

[0016] Preferably, both the bottom of the detection box and the control console are bolted with a support base, which is L-shaped.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This application sets up an automatic opening mechanism. When the protective cover needs to be opened, the electric push rod retracts. The telescopic end of the electric push rod drives the rotating ball to rotate outside the fixed shaft. Since the fixed shaft is fixed on both sides of the protective cover, the movement of the rotating ball causes the protective cover to rotate upward around the rotating connection point with the top of the rear side of the test box, thereby realizing the automatic opening of the protective cover. When the protective cover needs to be closed, the electric push rod extends. The telescopic end of the electric push rod pushes the rotating ball. The rotating ball drives the fixed shaft, causing the protective cover to rotate downward around the rotating connection point until the protective cover and the test box are in the appropriate closed position. The automatic telescopic action of the electric push rod replaces the complicated operation of manual pushing and rotating connection structure, which greatly improves the convenience and efficiency of operation.

[0019] 2. This application incorporates a sealing component and a sealing structure. The sealing component provides a seal during the closure of the protective cover. When the protective cover is closed, the sealing component tightly fits the gap between the test chamber and the protective cover to prevent salt spray leakage and ensure a good sealing effect. The sealing structure further secures the connection between the protective cover and the test chamber after the protective cover is closed, ensuring a tight connection between the two and preventing the protective cover from accidentally opening during the test. This ensures the stability and safety of the test environment. At the same time, the sealing structure and the sealing component work together to ensure both the sealing effect and the stability of the connection between the protective cover and the test chamber.

[0026] 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.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A salt spray test detection device includes a test chamber 1, a protective cover 2 on the top of the test chamber 1, the bottom of the rear side of the protective cover 2 being rotatably connected to the top of the rear side of the test chamber 1, an automatic opening mechanism 3 on both sides of the test chamber 1 and the protective cover 2, a sealing component 4 between the test chamber 1 and the protective cover 2, and a sealing structure 5 on the front side of the test chamber 1 and the protective cover 2.

[0029] The automatic opening mechanism 3 includes a fixed sleeve 301 bolted to both sides of the detection box 1. An electric push rod 302 is rotatably connected inside the fixed sleeve 301. Fixed shafts 303 are fixedly connected to both sides of the protective cover 2. A rotating ball 304 is fixedly connected to the telescopic end of the electric push rod 302. The rotating ball 304 is rotatably connected to the outside of the fixed shaft 303.

[0030] In this embodiment: by setting an automatic opening mechanism 3, when the protective cover 2 needs to be opened or closed, the extension and retraction of the electric push rod 302 can automatically drive the protective cover 2 to rotate around its rotating connection with the test chamber 1, realizing the rapid and accurate opening and closing of the protective cover 2, eliminating the need for complex manual operations. This greatly saves the user's operating time and effort, and improves the convenience and efficiency of operation. The advantages are even more obvious when the test device is used frequently. By setting a sealing component 4 and a sealing structure 5, when the protective cover 2 is closed, the sealing component 4 can effectively seal the gap between the test chamber 1 and the protective cover 2, preventing salt spray leakage and ensuring the airtightness of the test environment. The sealing structure 5 further fixes the connection between the protective cover 2 and the test chamber 1, preventing the protective cover 2 from being accidentally opened during the test, ensuring the stability and safety of the test environment. The two work together to provide good environmental conditions for the salt spray test, which is conducive to improving the accuracy of the test results.

[0031] Specifically, such as Figure 4 As shown, the sealing assembly 4 includes a sealing groove 401 opened on the top of the test box 1, and an adhesive piece 402 is provided on the bottom side inside the sealing groove 401.

[0032] Specifically, such as Figure 4As shown, a sealing gasket 403 is bolted to the bottom of the protective cover 2. The sealing gasket 403 is snapped into the inside of the sealing groove 401, and the bottom of the sealing gasket 403 contacts the top of the adhesive piece 402.

[0033] Specifically, such as Figure 4 As shown, a sealing gasket 404 is fixedly connected to the inner side of the sealing gasket 403. The bottom of the sealing gasket 404 contacts the inner side of the top of the test box 1. The sealing gasket 404 is located inside the sealing groove 401.

[0034] In this embodiment, a multi-layered sealing structure is formed by the arrangement of the sealing groove 401, the bonding piece 402, the sealing gasket 403, and the sealing pad 404. The sealing gasket 403 is snapped into the sealing groove 401 and its bottom contacts the bonding piece 402. The bottom of the sealing pad 404 contacts the inner side of the top of the test chamber 1 and is located inside the sealing groove 401. This structure can effectively prevent salt spray from leaking from the gap between the test chamber 1 and the protective cover 2. Compared with a single sealing method, the multi-layered sealing greatly improves the sealing effect, ensures the airtightness of the test environment, and is conducive to the accurate conduct of the salt spray test.

[0035] Specifically, such as Figure 5 As shown, the sealing structure 5 includes a fixing plate 501 bolted to the top of the front side of the test box 1, and a positioning hole 502 is provided on the top of the fixing plate 501.

[0036] Specifically, such as Figure 5 As shown, a connecting plate 503 is fixedly connected to the front side of the protective cover 2, and a positioning post 504 is fixedly connected to the bottom of the connecting plate 503. The positioning post 504 is snapped into the inside of the positioning hole 502.

[0037] In this embodiment, the positioning pin 504 on the connecting plate 503 is engaged with the positioning hole 502 on the fixing plate 501. This structure is simple and stable. When the protective cover 2 is closed, the positioning pin 504 is accurately engaged with the positioning hole 502, which can effectively prevent the protective cover 2 from opening due to accidental vibration or other reasons during the test, thus ensuring the stability of the test environment. At the same time, this engagement method is easy to operate and further improves the ease of use of the device.

[0038] Specifically, such as Figure 1 As shown, a control console 6 is bolted to the right side of the detection box 1, and the control console 6 is electrically connected to the electric push rod 302.

[0039] Specifically, such as Figure 1 As shown, both the bottom of the detection box 1 and the control console 6 are bolted with support bases 7, which are L-shaped.

[0040] In this embodiment: the control console 6 is electrically connected to the electric push rod 302, which allows the user to control the electric push rod 302 from one side of the test box 1, realizing the automatic opening and closing of the protective cover 2. This improves the convenience and controllability of operation. The user does not need to look for different control components around the device. The support base 7 is L-shaped, which can provide stable support for the test box 1 and the control console 6, ensuring that the device will not affect the test results due to shaking during the test, thus ensuring the accuracy and stability of the test.

[0041] Working principle: During the use of the salt spray test detection device, when it is necessary to open the protective cover 2, the user issues a command through the control console 6. The control console 6 controls the electric push rod 302 to retract. The telescopic end of the electric push rod 302 drives the rotating ball 304 to rotate outside the fixed shaft 303. Since the fixed shaft 303 is fixed on both sides of the protective cover 2, the movement of the rotating ball 304 causes the protective cover 2 to rotate upward around the rotating connection point with the rear top of the test chamber 1, thereby realizing the automatic opening of the protective cover 2. When it is necessary to close the protective cover 2, the control console 6 controls the electric push rod 302 to extend. The telescopic end of the electric push rod 302 pushes the rotating ball 304. The rotating ball 304 drives the fixed shaft 303, causing the protective cover 2 to rotate downward around the rotating connection point until the protective cover 2 and the test chamber 1 are in the appropriate closed position. Simultaneously, during the closing process of the protective cover 2, the sealing gasket 403 at the bottom of the protective cover 2 is engaged in the sealing groove 401 at the top of the test chamber 1. The bottom of the sealing gasket 403 contacts the fitting piece 402 inside the sealing groove 401. At the same time, the bottom of the sealing gasket 404 on the inner side of the sealing gasket 403 contacts the inner side of the top of the test chamber 1 and is located inside the sealing groove 401, forming a multi-layer seal, which effectively prevents salt spray leakage. When the protective cover 2 is closed in place, the positioning post 504 at the bottom of the connecting plate 503 on the front side of the protective cover 2 is engaged in the positioning hole 502 of the fixing plate 501 on the top front side of the test chamber 1, which effectively prevents the protective cover 2 from being accidentally opened during the test, ensuring the stability of the test environment. The overall coordination provides good environmental conditions for the salt spray test, which is conducive to improving the accuracy of the test results.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
