Description

Technical Field

[0001] This utility model relates to the field of environmental testing equipment technology, and in particular to a sealing structure for a temperature, humidity and vibration integrated test chamber. Background Technology

[0002] As industrial products face increasingly stringent quality requirements, manufactured products must undergo simulated testing before entering the market. This testing must accurately simulate the actual conditions of the product during use. Temperature, humidity, and vibration integrated test chambers can simulate and test the performance of products under various environmental conditions, including temperature, humidity, and vibration, to ensure the reliability and durability of the tested materials in extreme environments. These chambers are widely used in electronics, machinery, aerospace, automotive, and materials science, among other fields.

[0003] Existing temperature, humidity and vibration integrated test chambers switch between simulated and tested environments by moving the chamber to different test benches. When conducting vibration tests, the test chamber with an opening on the bottom plate needs to be moved to the top of the vibration table. Therefore, a sealing structure that is easy to frequently disassemble and assemble needs to be set up between the test chamber and the vibration table to ensure the sealing effect without affecting the vibration test results. Utility Model Content

[0004] To address the shortcomings of existing temperature and humidity vibration test chambers, such as inconvenience in operation and poor sealing effect when frequently disassembling and assembling the sealing structure, the applicant provides a sealing structure for a temperature and humidity vibration test chamber with a reasonable structure. This structure has two layers of high tear-resistant silicone cloth fixed on both sides of the vibration table. The other end of the vibration table cloth is equipped with Velcro and a metal ring to achieve a detachable connection with the bottom plate of the test chamber, which ensures the sealing effect while facilitating frequent disassembly and assembly.

[0005] The technical solution adopted in this utility model and its beneficial effects are as follows:

[0006] A sealing structure for a temperature, humidity and vibration integrated test chamber is provided, which is set between the bottom plate of the test chamber and the vibration table. The sealing structure includes a first vibration table cloth and a second vibration table cloth, one end of which is fixed to both sides of the vibration table. The other end of the first vibration table cloth is provided with Velcro, and the other end of the second vibration table cloth is provided with a metal ring. The other ends of the first vibration table cloth and the second vibration table cloth are detachably connected to the bottom plate of the test chamber.

[0007] As a further improvement to the above technical solution:

[0008] The second vibration table is located inside the first vibration table, and the length of the first vibration table is less than the length of the second vibration table.

[0009] The second vibration table cloth of this invention is pressed onto the bottom plate of the test chamber by a metal ring at one end, and the Velcro at one end of the first vibration table cloth is attached to the edge of the opening of the bottom plate of the test chamber for easy frequent disassembly and assembly. The two layers of vibration table cloth can ensure the sealing effect.

[0010] The vibration table surface has recessed grooves around its perimeter. Pressure plates are installed above one end of the first and second vibration cloths, and are secured within the recessed grooves using fasteners. The recessed grooves facilitate the securing of the first and second vibration cloths. The pressure plates within the grooves allow for tighter clamping of the first and second vibration cloths using fasteners, while also increasing the usable area of ​​the vibration table surface.

[0011] Both the first and second vibration table cloths are made of high tear-resistant silicone cloth. This high tear-resistant silicone cloth is resistant to both high and low temperatures, preventing damage under prolonged vibration and maintaining proper temperature and humidity within the test chamber, resulting in a good seal.

[0012] The outer surface of the second vibration table has aerogel to prevent frost and ice formation inside the test chamber. Attached Figure Description

[0018] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0019] like Figure 1-4As shown, the sealing structure of this utility model is set between the bottom plate of the test chamber 1 and the vibration table 2. The sealing structure includes two first vibration cloths 3 fixed on both sides of the vibration table 2 and two second vibration cloths 4 located inside them. The length of the first vibration cloths 3 is shorter than the length of the second vibration cloths 4. Both are made of high tear-resistant silicone cloth material, which has the characteristics of high and low temperature resistance. The four edges of the vibration table 2 are provided with grooves 22. Pressure plates 21 are set above one end of the first vibration cloths 3 and the second vibration cloths 4 and are fixed in the grooves 22 by fasteners. The upper surface of the pressure plate 21 is basically flush with the vibration table 2, so as to avoid the pressure plate 21 and the two vibration cloths protruding from the vibration table 2, which can increase the usable area of ​​the vibration table 2. The other end of the second vibration table cloth 4 is attached with a stainless steel metal ring 41. The weight of the metal ring 41 presses the second vibration table cloth 4 onto the bottom plate of the test chamber 1, thus achieving a seal and preventing gas and liquid leakage from the test chamber 1. Aerogel is attached to the outer side of the second vibration table cloth 4 for heat insulation, preventing frost and ice formation inside the test chamber 1. The other end of the first vibration table cloth 3 is attached to the edge of the opening in the bottom plate of the test chamber 1 with Velcro 31, making it easy to install and remove and preventing external air from entering the interior of the test chamber 1.

[0020] When a vibration test is required, the test chamber 1 is moved above the vibration table 2. One end of the second vibration table cloth 4 is pressed onto the bottom plate of the test chamber 1 by a metal ring 41, and the Velcro 31 of one end of the first vibration table cloth 3 is attached to the edge of the opening of the bottom plate of the test chamber 1. The seal between the test chamber 1 and the vibration table 2 can be achieved by the hook and loop layers of the Velcro 31 being adhered together. When it is necessary to separate the test chamber 1 and the vibration table 2, the hook and loop layers of the Velcro 31 are torn off and the second vibration table cloth 4 is lifted to separate the first vibration table cloth 3, the second vibration table cloth 4 and the test chamber 1.

[0021] The above description is an explanation of the present utility model and not a limitation thereof. The present utility model can be modified in any form without departing from its spirit.
