Abstract
Description
Technical Field
[0001] This utility model relates to the field of test chamber nozzle technology, specifically an automatic telescopic nozzle mechanism for an environmental test chamber. Background Technology
[0002] Environmental test chambers frequently perform salt spray tests, primarily used to evaluate the corrosion resistance of products or materials. By simulating a salt spray environment, they test the corrosion performance of products or materials under specific conditions. Salt spray test chambers can simulate the climatic conditions of high-salt environments such as oceans and salt lakes, providing a rigorous corrosion resistance testing environment for products. Salt spray testing in environmental test chambers has wide applications in various fields, including materials science, automotive parts, electronics, hardware products, and aerospace, and is one of the essential testing equipment for product development and quality control in enterprises and research institutions.
[0003] Since salt spray testing requires nozzles to spray salt water, the nozzles atomize the salt solution into fine particles to ensure the uniformity and consistency of the salt spray. In the existing technology, the nozzles in the test chamber are fixed. When water spraying is not required, the nozzles in the chamber can hinder the operation. In addition, the temperature inside the test chamber can change, sometimes being very high or very low. The temperature of the nozzles inside the chamber will rise or fall accordingly, causing the liquid inside the nozzles to overheat or freeze, thus affecting the spray temperature of the water spray test.

A pair of nozzle components are symmetrically installed at both ends of the outer side of the rectangular bracket.
[0008] Furthermore, the slide support frame consists of a pair of slide trays symmetrically spliced together, each slide tray being a sheet metal folding piece with a triangular front and a rectangular top view.
[0009] Furthermore, the sliding component includes a slide rail assembly and a rodless cylinder. The slide rail assembly is mounted on a rectangular surface of one side of the slide plate, and the rodless cylinder is mounted on a rectangular surface of the other side of the slide plate.

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.
[0024] Please see Figure 1-5An automatic telescopic nozzle mechanism for an environmental test chamber is installed on the surface of the chamber body 1. It includes a first nozzle assembly 2 installed on the rear of the chamber body 1 and a second nozzle assembly 3 installed on the side of the chamber body 1. The first nozzle assembly 2 and the second nozzle assembly 3 have the same structure but different lateral lengths. The first nozzle assembly 2 includes a pair of sliding support frames 201 symmetrically installed on the surface of the chamber body 1. Each sliding support frame 201 consists of a pair of symmetrically spliced sliding trays 2011. 011 is a sheet metal folding part, with a triangular front view and a rectangular top view. Each slide support 201 is equipped with a sliding component 202, which includes a slide rail assembly 2021 and a rodless cylinder 2022. The slide rail assembly 2021 is mounted on the rectangular surface of one side of the slide support 2011, and the rodless cylinder 2022 is mounted on the rectangular surface of the other side of the slide support 2011. A U-shaped support 2023 is mounted on the slide rail assembly 2021, with its upper end fixedly connected to the bottom surface of the rectangular bracket 203. The rodless cylinder 2022... An L-shaped connector 2024 is installed on the sliding member 202, and the other side of the L-shaped connector 2024 is fixedly connected to the side of the rectangular bracket 203. The rectangular bracket 203 is installed on the sliding member 202. The rectangular bracket 203 is composed of a first horizontal beam 2031 and two first vertical beams 2032. A second horizontal beam 2033 is spliced between the two first vertical beams 2032. The installation position of the second horizontal beam 2033 is lower than the front end face of the two first vertical beams 2032. A pair of [unclear text - possibly referring to components or elements] are symmetrically installed on the outer surface of the second horizontal beam 2033. A second vertical beam 2034 with its front end flush with the front end; a pair of nozzle components 204 are symmetrically installed at both ends of the outer side of the rectangular bracket 203; the nozzle component 204 includes a nozzle connecting plate 2041 installed between each first vertical beam 2032 and the second vertical beam 2034, and each nozzle connecting plate 2041 is equipped with a nozzle upper plate 2042 and a nozzle lower plate 2043, both of which are fan-shaped and assembled together; a pipe elbow 4 is installed below the nozzle component 204, and the pipe elbow 4 is connected to the water supply pipe.
[0025] In the above-described embodiment, a nozzle baffle 5 that can move up and down is installed at the opening of the housing where the first nozzle assembly 2 and the second nozzle assembly 3 are installed. A nozzle protective cover 6 is installed on the side of the environmental test chamber body 1 at the location of the second nozzle assembly 3. The nozzle protective cover 6 covers the second nozzle assembly 3. The location of the first nozzle assembly 2 needs to be connected to other units. Therefore, the first nozzle assembly can be located inside other units without the need to install a nozzle protective cover.
[0026] The working principle of the above embodiments is as follows:
[0027] In the diagram: 1. Main body of the environmental test chamber; 2. First nozzle assembly; 201. Slide support frame; 2011. Slide support plate; 202. Sliding component; 2021. Slide rail assembly; 2022. Rodless cylinder; 2023. U-shaped support; 2024. L-shaped connector; 203. Rectangular bracket; 2031. First crossbeam; 2032. First vertical beam; 2033. Second crossbeam; 2034. Second vertical beam; 204. Nozzle assembly; 2041. Nozzle connecting plate; 2042. Nozzle head upper plate; 2043. Nozzle head lower plate; 3. Second nozzle assembly; 4. Pipe elbow; 5. Nozzle baffle; 6. Nozzle protective cover.
[0028] In use, the pipe elbow 4 is first connected to the water pump device through the water supply pipe. When water spraying is required, the pneumatic device provides forward power to the rodless cylinder 2022. The rodless cylinder 2022 pushes the rectangular bracket 203 forward through the L-shaped connector 2024. The rectangular bracket 203 slides on the slide rail assembly 2021 through the U-shaped support 2023. Then, the rectangular bracket 203 drives the nozzle components at both ends to extend forward into the interior of the environmental test chamber body 1. The water pump starts to work, and water is sprayed from the pipe elbow 4 to the nozzle component 204 through the water supply pipe. When the water spraying test ends, the rodless cylinder 2022 extends and retracts, causing the nozzle component 204 to exit the exterior of the environmental test chamber body 1. Then, the nozzle baffle inside the chamber randomly falls down to block the window position corresponding to the first nozzle component 2. The working principle of the first nozzle component 2 and the second nozzle component 3 is the same.
[0029] In summary, the automatic telescopic nozzle mechanism of this environmental test chamber changes the nozzle component 204 from being fixed inside the chamber to being able to move in and out of the chamber as needed by being driven by the rodless cylinder 2022. This solves the technical problem in existing environmental test chambers where the nozzle component inside the chamber hinders operation when water spraying is not required. In addition, having the nozzle component outside the chamber when water spraying is not required prevents the liquid inside the nozzle component from overheating or freezing due to temperature changes inside the chamber, which would affect the water spraying temperature during the water spraying test and improve the reliability of the environmental test chamber during salt spray testing.
