Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to a constant temperature and humidity test chamber for plastic products. Background Technology

[0002] A constant temperature and humidity test chamber, also known as a constant temperature and humidity test machine, constant temperature and humidity test chamber, programmable damp heat alternating test chamber, constant temperature machine, or constant temperature and humidity chamber, is a device used to test the performance of materials under various environments and to test the heat resistance, cold resistance, dryness resistance, and humidity resistance of various materials. It is suitable for quality testing of electronic, electrical, mobile phone, communication, instrument, vehicle, plastic products, metal, food, chemical, building materials, medical, aerospace and other products. Its application is very wide, and most plastic products need to be tested in a constant temperature and humidity chamber during the design process.

[0003] Existing temperature and humidity test chambers for plastic products have the following drawbacks during use: existing temperature and humidity test chambers are generally of traditional chamber structure with small internal space. When testing longer products such as plastic tubes, only a small section can be cut for testing. For long plastic tubes that have already been formed, it is inconvenient to conduct random inspections. Therefore, we propose a temperature and humidity test chamber for plastic products. Utility Model Content

[0004] The main purpose of this utility model is to provide a constant temperature and humidity test chamber for plastic products. By setting a support mechanism on the surface of the chamber, it is possible to perform testing operations on long plastic tubes when needed, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A constant temperature and humidity test chamber for plastic products includes a chamber body and a support mechanism. The surface of the chamber body is provided with a support mechanism for fixing plastic tubes. The support mechanism includes an extension tube, an arc-shaped bracket, a movable pressure ring, and a screw. Both sides of the surface of the chamber body are provided with extension tubes that are correspondingly positioned and connected to the interior of the chamber body. An arc-shaped bracket is fixedly connected to one end of the extension tube near the chamber body, and the top of the arc-shaped bracket is movably connected to the movable pressure ring through a screw.

[0007] Furthermore, it also includes auxiliary mechanisms. These mechanisms are located on both sides of the interior of the housing. Each auxiliary mechanism includes a slot, a cylinder, and an isolation plate. Slots are vertically formed on both sides of the interior of the housing. An isolation plate, inserted into the slot, is installed at the power output end of the cylinder. The isolation plates are connected to both sides of the housing via the slots. During normal testing, the isolation plates are fully inserted into the slots, isolating the interior of the housing from the extension tube and reducing heat loss from the housing. When tube testing is required, the cylinder is controlled to operate, and its power end lifts the isolation plate, allowing the extension tube end to be unobstructed for installation and testing. This method is convenient to use.

[0008] Furthermore, each end of the extension tube away from the housing is connected to an end cap for controlling the opening and closing of the extension tube; the opening and closing of the end of the extension tube can be controlled by the end cap structure connected to the end of the extension tube.

[0009] Furthermore, a threaded hole is provided at the top of the extension tube corresponding to the position of the movable pressure ring, and the threaded hole is connected to the screw. The end of the screw is connected to the top of the movable pressure ring. The vertical height of the movable pressure ring can be adjusted by turning the screw along the threaded hole.

[0010] Furthermore, a rubber gasket is bonded to the outer periphery of the isolation plate to increase the sealing of the connection; the rubber gasket structure can ensure the sealing of the connection when the isolation plate is closed.

[0011] Compared with the prior art, this utility model has the following advantages: Under normal testing conditions, the isolation plate is closed, and the item to be tested is placed inside the chamber for normal testing. When it is necessary to perform constant temperature and humidity sampling inspection on pre-formed tubular components, the isolation plate and end cap can be opened, the tubular component can be horizontally inserted into the extension tube and through the chamber, the position of the tubular component to be tested can be adjusted to the inside of the chamber, and then the adjusting screw can be turned so that the movable clamping ring and the arc-shaped bracket can cooperate to clamp and fix the position of the tubular component, while closing the end of the extension tube to reduce heat loss. This allows for testing of pre-formed tubular components under specific temperature and humidity conditions, making it more widely applicable. The two sides of the chamber are connected to the isolation plate through slots. During normal testing, the isolation plate is fully inserted into the slot, isolating the connection between the inside of the chamber and the extension tube, reducing the heat loss inside the chamber. When tubular testing is required, the cylinder is controlled to operate, and its power end lifts the isolation plate to allow the end of the extension tube to pass smoothly, thus enabling the installation and testing of the tubular component. This is convenient to use. Attached Figure Description

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] like Figure 1-3 As shown, a constant temperature and humidity test chamber for plastic products includes a chamber body 1 and a support mechanism 2. The support mechanism 2 for fixing plastic tubes is provided on the surface of the chamber body 1. The support mechanism 2 includes an extension tube 201, an arc-shaped bracket 203, a movable pressure ring 204, and a screw 206. Extension tubes 201 with corresponding positions and communicating with the interior of the chamber body 1 are provided on both sides of the surface of the chamber body 1. An arc-shaped bracket 203 is fixedly connected to one end of the extension tube 201 near the chamber body 1, and the top of the arc-shaped bracket 203 is movably connected to the movable pressure ring 204 through the screw 206.

[0018] The system also includes an auxiliary mechanism 3. The auxiliary mechanism 3 is located on both sides of the interior of the housing 1. The auxiliary mechanism 3 includes a slot 301, a cylinder 302, and an isolation plate 303. Slots 301 are vertically opened on both sides of the interior of the housing 1. An isolation plate 303, inserted into the slot 301, is installed at the power output end of the cylinder 302. The isolation plates 303 are connected to both sides of the housing 1 via the slots 301. During normal testing, the isolation plates 303 are fully inserted into the slots 301, isolating the interior of the housing 1 from the extension tube 201 and reducing heat loss inside the housing 1. When tube testing is required, the cylinder 302 is controlled to operate, and its power end lifts the isolation plate 303, allowing the extension tube 201 to be unobstructed for installation and testing. This system is convenient to use.

[0019] The extension tube 201 is connected to an end cap 202 at the end away from the housing 1 to control the opening and closing of the extension tube 201. The top of the extension tube 201 is provided with a threaded hole 205 corresponding to the position of the movable pressure ring 204, and is connected to a screw 206 through the threaded hole 205. The end of the screw 206 is connected to the top of the movable pressure ring 204. The opening and closing of the end of the extension tube 201 can be controlled by the structure of the end cap 202 inserted into the end of the extension tube 201. The vertical height of the movable pressure ring 204 can be adjusted by turning the screw 206 along the threaded hole 205.

[0020] The outer periphery of the isolation plate 303 is bonded with a rubber gasket 304 to increase the sealing of the connection; the structure of the rubber gasket 304 can ensure the sealing of the connection when the isolation plate 303 is closed.

[0021] It should be noted that this utility model is a constant temperature and humidity test chamber for plastic products. During normal testing, the isolation plate 303 is closed, and the item to be tested is placed inside the chamber 1 for normal testing. When it is necessary to perform constant temperature and humidity sampling inspection on pre-formed tubular components, the isolation plate 303 and end cap 202 can be opened. The tubing can be horizontally inserted into the extension tube 201 and through the chamber 1. The position of the tubing to be tested is adjusted inside the chamber 1. Then, the adjusting screw 206 is turned so that the movable clamping ring cooperates with the arc-shaped bracket 203 to clamp and fix the position of the tubing. At the same time, the extension tube 201 is closed. 01. By reducing heat loss at the end, it is possible to perform testing operations on the formed pipe fittings under specific temperature and humidity conditions, making it more widely applicable. Both sides of the box body 1 are connected to the isolation plate 303 through the slot 301. During normal testing operations, the isolation plate 303 is fully inserted into the slot 301, isolating the connection between the inside of the box body 1 and the extension pipe 201, reducing the temperature loss inside the box body 1. When pipe testing is required, the control cylinder 302 is operated, and its power end lifts the isolation plate 303 to make the end of the extension pipe 201 unobstructed, so that the pipe can be installed and tested, which is convenient to use.
