Description

Technical Field

[0001] This utility model belongs to the technical field of salt spray corrosion test chambers, and in particular relates to a salt spray corrosion test chamber for automotive parts. Background Technology

[0002] A salt spray corrosion test chamber for automotive parts (commonly referred to as a salt spray test chamber or salt spray box) is a specially designed environmental simulation test device used to accelerate the evaluation of the corrosion resistance of automotive parts and their surface coatings (such as paint, electroplating, conversion film, etc.) in a salty and humid atmospheric environment.

[0003] Currently, when using the test chamber, multiple samples need to be placed at a predetermined angle. However, when there are many samples to be tested, the placement is relatively dense, which can easily lead to overlapping and obstruction, thus affecting the accuracy of the test results.

[0004] To address the aforementioned issues, this application proposes a salt spray corrosion test chamber for automotive parts. Utility Model Content

[0005] The purpose of this invention is to provide a salt spray corrosion test chamber for automotive parts, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a salt spray corrosion test chamber for automotive parts, including a test chamber; A side frame is rotatably installed inside the side wall of the test chamber, and its lower end swings back and forth. An upper support rod is fixed inside the upper end of the side frame, and a slide that drives the side frame to swing is slidably installed inside the upper end of the side wall of the test chamber. The side frame is slidably mounted with a slide block through a slide rail on its inner side. The slide block is movably connected to a positioning hole in the slide rail. A support net is rotatably mounted on the inner side of the slide block to support the lower end of the template.

[0007] Preferably, a baffle is fixed to the inner side of the upper end of the side wall of the test chamber to isolate the carriage.

[0008] Preferably, a fixing frame is fixed to the inner side wall of the test chamber, and the upper end of the slide is slidably connected to the fixing frame.

[0009] Preferably, the lower end of the carriage has a protruding plate adjacent to the protrusion at the upper end of the side frame.

[0010] Preferably, the two ends of the support net are fixed with turntables that are rotatably connected to the slide, and the inner side of the slide is fixed with a pressure rod located on the outer side of the support net.

[0011] Preferably, the upper end of the slide has a three-way opening groove that extends from front to back, with the third opening extending upwards. A transition block is slidably installed in the three-way opening groove to connect adjacent three-way opening grooves.

[0012] Preferably, the outer side of the slide block has a protruding slider that is slidably connected to the slide rail, and the hole on the side of the slider is fitted with a positioning pin that engages with the positioning hole through a built-in spring rod, and the end of the positioning pin has a tapered structure.

[0013] This utility model has the following beneficial effects: This utility model uses a swing-type installation of the side frame, combined with the thrust of the slide to control the placement angle of the side frame, which can adjust the tilt angle of the template during the test, making it convenient to test templates of different sizes. Furthermore, by connecting adjacent slide blocks, one slide can slide down individually or multiple slides can slide down simultaneously, thereby adjusting the height of the support point at the lower end of the template. This ensures that the upper end extends to the same height, avoiding mutual obstruction and overlap, and ensuring the accuracy of the test results.

[0018] In the description of this utility model, it should be understood that the terms "opening", "top and bottom", "thickness", "top", "middle", "length", "inner" and "around" indicate the orientation or positional relationship only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0019] Please see Figure 1-5 As shown, this utility model is a salt spray corrosion test chamber for automotive parts, including a test chamber 11; A side frame 14 is rotatably installed inside the side wall of the test chamber 11. The upper end of the frame is rotatably connected to the side wall of the test chamber 11, and the lower end swings back and forth. The upper end of the adjacent side frames 14 inside the two side walls is fixed with an upper support rod 12 for placing a sample to form support. A slide 17 is slidably installed inside the upper end of the side wall of the test chamber 11 for driving the lower end of the side frame 14 to swing back and forth. The side frame 14 is slidably mounted with a slide block 15 through a slide rail 141 on the inner side. A slider 154 protrudes from the side of the slide block 15 and is slidably connected to the slide rail 141. The slide block 15 is movably connected to the positioning hole 142 in the slide rail 141 through the slider 154. A support net 16 with a semi-circular structure is rotatably mounted on the inner side of the slide block 15, with its opening facing the support rod 12, for supporting the lower end of the template. Furthermore, a baffle 13 is fixed to the inner side of the upper end of the side wall of the test chamber 11 to isolate the slide 17 and prevent it from being affected by the salt spray test and the electric telescopic device that is fixedly connected to the front wall of the test chamber 11.

[0020] Furthermore, a fixing frame 18 is fixed to the inner side wall of the test chamber 11, and an inverted T-shaped block structure extends from its lower end, which is slidably connected to the upper open inverted T-groove of the slide 17.

[0021] Furthermore, a protruding plate 171 extends from the lower end of the slide 17, located on one side of the upper protrusion 143 when the side frame 14 is in the vertical state. When the slide 17 slides backward, the protruding plate 171 exerts a pushing force on the protrusion 143, causing the lower end of the side frame 14 to swing forward.

[0022] Furthermore, turntables 161 that are rotatably connected to slides 15 are fixed at both ends of the support net 16, and pressure rods 151 are fixed on the inner side of slides 15, located on the outer side of the support net 16. The sliding of slides 15 is controlled by pressing down or lifting the pressure rods 151.

[0023] The upper end of the slide block 15 has a three-way opening groove 152 that runs from front to back, with the third opening running upward. A transition block 153 is slidably installed in the three-way opening groove 152. The rear end of the transition block 153 extends backward to connect the adjacent three-way opening groove 152. The front end of the transition block 153 is an upwardly protruding push block structure that protrudes outward through the upper opening of the three-way opening groove 152.

[0024] In addition, a slider 154 protrudes from the outer side of the slide block 15 and is slidably connected to the slide rail 141. A hole is opened on the side of the slider 154, and a positioning pin 155 is fixed in the hole by a spring rod. One end of the positioning pin 155 is a conical block structure that engages with the positioning hole 142.

[0025] It is understood that this utility model can conveniently adjust the tilt angle of the sample and the height of the bottom support point of different samples during the salt spray test, thereby controlling the upper exposed height of the sample to be consistent, so as to receive equal salt spray test, avoid the overlap caused by some samples being too high and some samples being too low, and ensure the accuracy of the salt spray test results.

[0026] A specific application of the operation process of this embodiment is as follows: In use, firstly, by sliding the slide 17 back and forth, the convex plate 171 moves the convex block 143, causing its lower end to swing back and forth, so as to adjust the angle when the template is placed; further, the adapter block 153 is moved to slide and connect to the three-way opening groove 152 at the upper end of the adjacent slide block 15, and then the pressure rod 151 is pressed down or raised, which can drive the adjacent slide block 15 to move up and down at the same time; when the pressure rod 151 is pressed down or raised, the positioning pin 155 on the outside of the slide block 15 is guided by its conical surface, and the spring rod is compressed, so that the positioning pin 155 moves out of the positioning hole 142 and enters the next positioning hole 142 to form a snap, thereby achieving the effect of adjusting the height of the support net 16 and thus adjusting the exposed height of the top of the template.
