Description

Technical Field

[0001] The utility model belongs to the technical field of test chamber equipment, and specifically relates to a vibration test bench structure of an environmental test chamber. Background Art

[0002] An environmental test chamber, also known as a three-in-one test chamber, mainly consists of three core parts: a test chamber body, a lifting table, and a vibration table. These three parts cooperate together to enable the test chamber to simulate three extreme environmental conditions: temperature, humidity, and vibration. Such a test chamber is of extremely important significance for multiple key fields, such as aerospace, electronic communication, automobile manufacturing, military industry, etc. It can ensure that the equipment developed in these fields can still operate normally under extreme environments, thereby guaranteeing the reliability and stability of the products. Therefore, the environmental test chamber plays an indispensable role in the product R & D and product delivery processes.

[0003] Currently, in the existing technology, the environmental test chamber can test the temperature and humidity of products, and the vibration table can test the vibration of products. When conducting comprehensive tests on products for temperature, humidity, and vibration, it is necessary to connect the vibration table to the test chamber body. When connecting them, the vibration table is often placed at the bottom of the test chamber body, so that the tabletop of the vibration table extends into the interior of the test chamber, and then the vibration table is connected to the test chamber body by using a connecting leather. In such a connection method, both the connecting leather can ensure that the product to be tested is kept in a closed temperature and humidity detection environment, and the vibration table can make the product to be tested vibrate continuously to complete the test of the product.

[0004] However, in the process of connecting the vibration table to the test chamber by using the connecting leather, it is fixed by using a pressing plate or a pressing strip in cooperation with screws, which makes the connection, disassembly, and replacement of the table tool between the vibration table and the test chamber cumbersome. When using the pressing strip for fixing, there will also be a raised circle at the edge of the tabletop of the vibration table, which is not conducive to the placement of the product to be tested. Summary of the Utility Model

[0005] In order to solve the technical problem that the connection, disassembly, and replacement of the table tool between the vibration table and the test chamber are relatively cumbersome in the existing technology, the utility model provides a vibration test bench structure of an environmental test chamber.

[0006] The purpose of the utility model can be realized by the following technical solutions:

[0007] A vibration test bench structure of an environmental test chamber includes a vibration table placed below the test chamber; a tabletop is fixedly connected to the upper part of the vibration table; a connecting leather is arranged in a fitting manner on the upper part of the tabletop, and the upper end edge of the connecting leather is connected to the vibration table;

[0009] Furthermore, an adsorption block is fixedly connected to the fixing plate at a position corresponding to the fixing hole; the adsorption block is fitted with the fixing hole.

[0010] Furthermore, a cavity is provided inside the table top panel; a first connector communicating with the cavity is fixedly connected to the side surface of the table top panel, and the first connector is connected to a vacuum generator through a hose; a plurality of adsorption holes are uniformly provided at positions corresponding to the cavity on the table top panel, and the adsorption holes penetrate to the upper surface of the fixing plate.

[0011] Furthermore, a one-way valve is fixedly provided inside the adsorption hole.

[0013] Furthermore, drain holes are uniformly provided at positions corresponding to the spaces between the fixing holes at the edge of the table top panel; a drain port is provided inside the table top panel at a position corresponding to the drain hole, and the drain port penetrates to the side surface of the table top panel.

[0014] Furthermore, the drain port is in an inclined structure.

[0016] 1) When the present utility model connects the connecting leather and the table top panel by using the fixing plate, the adsorption block on the lower surface of the fixing plate can be directly aligned with the fixing hole and inserted, and then the adsorption block is adsorbed and fixed by the cooperation of the vacuum generator and the through hole, so as to firmly fix the fixing plate on the table top panel, achieving the purpose of fixing the connecting leather. Moreover, when disassembling, installing, and replacing the table tool, it can be directly removed, which is fast, convenient, simple to operate, and there will be no protruding part affecting the placement of the product to be tested.

[0017] 2) After the present utility model connects the connecting leather and the table top panel through the fixing plate, the article to be tested can be directly placed on the upper part of the fixing plate.

The fixing and disassembling methods are fast and convenient, and the fixing position is relatively arbitrary, which has the advantages of saving worry and effort. When the product to be tested is in an irregular shape, it can be fixed by using screws and the internal threads of the adsorption holes, improving the applicability of the equipment under different test conditions.

[0018] 3) The utility model can quickly drain water droplets through the cooperation of the drain holes and the drain outlet, avoiding affecting the temperature and humidity test data. The inclined drain outlet can play a guiding role to prevent water from accumulating inside the drain outlet. Description of the Drawings
