Problems solved by technology

[0003] However, the above-mentioned case-expandable industrial control equipment still has obvious defects during use: 1. The above-mentioned device realizes the expansion of the case through the lifting method, but the overall lifting-type expansion method will cause the airtightness inside the box to be greatly reduced ,

Example Embodiment

[0033] Example 1:

[0034] An expandable case structure includes a heat dissipation base 1 and a case body 2 mounted on the upper part of the heat dissipation base 1. The heat dissipation base 1 is used to evacuate the heat transmitted from the heat dissipation base 1 to the external environment, so as to realize the external environment and the case body. 2 Exchange of internal temperature, the interior of the chassis body 2 is used to accommodate and carry working components, a chassis expansion port 3 is reserved on one side of the chassis body 2, and a flip plate 5 is movably installed at the bottom of the chassis expansion port 3 through the rotating shaft 4, and through the flip plate The closing of 5 closes the opening 3 of the chassis. Similarly, the opening of the chassis body 2 is realized by the opening of the flip plate 5. The flip plate 5 is movably matched with the opening 3 of the chassis, and the inner side of the flip plate 5 is used to carry the components 6. ...

Example Embodiment

[0038] Embodiment 2:

[0039] In this embodiment, heat-dissipating silica gel is coated between the heat-dissipating base 1 and the bottom of the case body 2 , and the heat-dissipating silica gel coating makes the heat inside the case body 2 diffuse to the heat-dissipating base 1 more quickly.

Example Embodiment

[0040] Embodiment three:

[0041] In this embodiment, a turning plate unfolding spring is inserted into the rotating shaft 4, and through the setting of the turning plate unfolding spring, when the spool 8 is unwound, the turning plate 5 is automatically opened under the action of the external force of the turning plate unfolding spring itself.

Abstract

The invention provides an unfoldable case structure and an air quality detector thereof.The unfoldable case structure comprises a heat dissipation base and a case body installed on the upper portion of the heat dissipation base, a case unfolding opening is reserved in one side of the case body, and a turnover plate is movably installed at the bottom of the case unfolding opening through a rotating shaft; the turnover plate is movably matched with an unfolding opening of the machine case, the wire coil is fixedly installed on the first driven shaft, and the expansion sealing film is tightly matched with the unfolding opening of the machine case in the expansion state. The turnover plate is arranged on the base, the working components are completely exposed to the external environment after being turned over, the S-shaped cooling groove is formed in the turnover plate, heat generated by the working components installed on the S-shaped cooling groove can be rapidly transmitted, the hydraulic sealing groove is formed in the periphery of the turnover plate, the problem that a case unfolding opening is poor in sealing performance is solved, and the practicability and sealing performance of the device are greatly improved.

Description

technical field [0001] The invention relates to the technical field of air detection cabinets, in particular to an expandable cabinet structure and an air quality detector thereof. Background technique [0002] In the prior art, a case-expandable industrial control device with a publication number of "CN209882342U" includes a case and a main board arranged in the case. There is a first chute, and card holes are provided on the upper side of the first chute. The rear shell of the chassis is provided with a wire placement slot. There is an unfolding mechanism sliding inside the chassis. The unfolding mechanism includes an L-shaped shell and two sets of side shells. The two sets of shells of the shell correspond to the front shell and the top shell that the chassis lacks respectively, and the L-shaped shell is snap-fitted with the chassis. Buckle, the second buckle is welded on the outer lower part of the side shell, and the first buckle and the second buckle are snapped and m...
