[0014] (III) Beneficial Effects

[0015] This utility model provides a conveniently assembled environmental testing chamber, which has the following advantages:

[0016] 1. This convenient, modular environmental testing chamber, through the design of pressurization and sealing components, allows the sliding frame to press against the surface of the test chamber body when the door is closed. This causes the sliding frame to compress the support spring, which in turn contracts, generating a spring force that pushes the sliding frame in the opposite direction. Simultaneously, the sealing strip on the inner frame presses against the inside of the door frame of the test chamber body, allowing the sealing strip to slide within the groove on the inner frame and compress the telescopic spring. The positioning rod remains in a stable position, thus achieving a multi-layer dynamic sealing effect. This prevents external dust and impurities from entering the equipment, which could lead to inaccurate test results and improve the detection accuracy of the environmental testing chamber.

[0017] 2. This convenient assembly-type environmental testing chamber, through the configuration of its installation components, allows for easy assembly of the arc-shaped spray pipe. When assembling the arc-shaped spray pipe, the conveying pipes at both ends of the arc-shaped spray pipe are aligned with the connecting pipe. The lower clamping ring is then inserted into the positioning plate and one end of the conveying pipe. Pulling the upper clamping ring causes one end of the upper clamping ring to press tightly against one end of the lower clamping ring. This allows the threaded bolt to be pulled into the groove, and the limiting nut is tightened, causing the limiting nut to rotate on the surface of the threaded bolt and press against the bottom surface of one end of the lower clamping ring. This achieves the effect of convenient assembly of the arc-shaped spray pipe, facilitating disassembly, maintenance, or replacement by personnel, thus improving the service life and convenience of the environmental testing chamber.

A door 5 is hinged to one side of the test chamber body 1, and a pressure-pressurizing component 6 is slidably connected to one side of the door 5. The pressure-pressurizing component 6 and the sealing component 8 achieve a multi-layer dynamic sealing effect, preventing external dust and impurities from entering. Entering the equipment causes inaccurate test results, improving the detection accuracy of the environmental test chamber. The inner frame 7 is fixedly connected to one side of the chamber door 5, and the sealing components 8 are slidably connected to all four sides of the inner frame 7. The installation component 4 includes an upper clamping ring 401 that is snapped onto the surface of the positioning piece 3, and a lower clamping ring 402 is rotatably connected to one side of the upper clamping ring 401. The pressurizing component 6 includes a sliding frame 601 that is slidably connected to one side of the chamber door 5, and several sets of support springs 602 are fixedly connected to one side of the sliding frame 601. The sealing component 8 includes a sealing strip 801 that is slidably connected to all four sides of the inner frame 7, and a telescopic spring 802 is fixedly connected to the bottom of the sealing strip 801. A positioning rod 803 is sleeved inside the telescopic spring 802.

[0026] A sealing ring 9 is snapped onto one side of the positioning piece 3, and a delivery pipe 10 is snapped onto the other side of the sealing ring 9. The delivery pipe 10 serves to deliver liquid.

[0027] One end of the delivery pipe 10 is connected to an arc-shaped spray pipe 11. Several sets of nozzles 12 are provided at the bottom of the arc-shaped spray pipe 11. The nozzles 12 facilitate spraying.

[0028] One end of the upper clamping ring 401 is rotatably connected to a threaded bolt 13, and the bottom of the threaded bolt 13 is threadedly connected to a limit nut 14. The limit nut 14 serves to fix and limit the position.

[0029] A support base 15 is fixedly connected to the inner bottom wall of the test chamber body 1, and a support plate 16 is fixedly connected to the top of the support base 15. The support plate 16 serves to support the material.

[0030] The inner frame 7 has a transparent observation window 17 inside, and the inner frame 7 has grooves around its perimeter that are compatible with the sealing strip 801. The grooves facilitate the sliding of the sealing strip 801.

[0031] A filter screen 18 is provided on the inner bottom wall of the test chamber body 1, and a control box 19 is fixedly connected to the surface of the test chamber body 1. The control box 19 plays a role in control and adjustment.

[0032] In this invention, the working steps of the device are as follows:

[0033] First step: When it is necessary to assemble the arc-shaped spray pipe 11, align the conveying pipes 10 at both ends of the arc-shaped spray pipe 11 with the connecting pipe 2, and then insert the lower clamping ring 402 into the positioning piece 3 and one end of the conveying pipe 10, and pull the upper clamping ring 401.

[0034] Second step: Make one end of the upper clamping ring 401 fit tightly against one end of the lower clamping ring 402, then pull the threaded bolt 13 into the groove, and turn the limiting nut 14 so that the limiting nut 14 rotates on the surface of the threaded bolt 13 and presses the bottom surface of one end of the lower clamping ring 402.

[0035] The third step: When the door 5 is closed, the sliding frame 601 presses against the surface of the test chamber body 1, causing the sliding frame 601 to press against the support spring 602. The support spring 602 contracts under force, generating an elastic force that pushes the sliding frame 601 in the opposite direction. At the same time, the sealing strip 801 on the inner frame 7 presses against the inside of the door frame of the test chamber body 1, causing the sealing strip 801 to slide in the groove on the inner frame 7 and press against the telescopic spring 802. The positioning rod 803 remains in a stable position. It should be noted that the device structure and drawings of this utility model mainly describe the principle of this utility model.
