Convenient-to-maintain case device special for automatic instruments and meters

Abstract

The invention provides a convenient-to-maintain case device special for automatic instruments and meters, and belongs to the technical field of automatic instruments and meters. The case device comprises a support assembly, a box opening assembly, a protection driving assembly, a top cover assembly, an axial flow heat dissipation assembly and an instrument board, and the support assembly is used as a fixed installation foundation on the whole; a box opening assembly is arranged on a box seat in the support assembly, and a front box plate, a rear box plate, a left box plate and a right box plate in the box opening assembly can be synchronously and automatically opened and closed, so that all-directional maintenance of instruments and meters is facilitated; the driving power of the box opening assembly is the protection driving assembly, the protection driving assembly is in matched transmission through a sliding boss fixed in a rotating belt wheel and a sliding groove formed in a rotating elastic base, a mechanism which is matched with sliding after super-torsion rotation and is ineffective in transmission is formed, and the situation that instruments and meters on an instrument board are damaged by the action of the box opening assembly can be prevented. The axial flow heat dissipation assembly is further arranged in the inner cavity formed by the box opening assembly, 360-degree rotation air suction heat dissipation can be achieved, and the beneficial effects of being good in heat dissipation effect and convenient and fast to operate are achieved.

Problems solved by technology

[0003] In the process of actual use, in addition to relying on the main body of the instrument, the chassis device used to fix the instrument also plays a very important role. The traditional chassis is mostly a closed sheet metal structure that can be opened on one side. There are heat dissipation devices or other auxiliary devices similar to spring shock absorption, such as a special case device for automatic instruments and meters disclosed in the prior art (CN 208029267 U), which includes a cabinet and a base. The upper end of the cabinet is provided with a cooling fan. There are sleeves on the left and right side walls of the cavity, and shock absorbing springs are arranged in the sleeves. One side of the shock absorbing springs is provided with a sleeve rod, and the sleeve rod is sleeved on the sleeve. One side of the sleeve rod is provided with a side plate, and the base There are sliding columns on the left and right side walls, and the supporting plate supporting the box is slidingly connected between the sliding columns. The bottom side wall of the base is provided with a first sliding cavity and a second sliding cavity. The downward movement of the supporting plate drives the first connecting The rod and the second connecting rod rotate, the lower end of the first connecting rod drives the first slider to move to the left side of the first sliding chamber, and squeezes the first compression spring to the left side wall of the first sliding chamber, and the lower end of the second connecting rod drives the first sliding block to move to the left side of the first sliding chamber. The second slider slides to the right side of the second sliding chamber, pressing the second compression spring to the right side wall of the second sliding chamber to play the role of shock absorption. This closed structure will not only improve the process of making the device It increases the difficulty of operation, and it is not convenient for subsequent maintenance due to the narrow operable space

[0004] In addition, the cooling device of the traditional instrument case is mostly driven by a simple convection exhaust fan, and the heat dissipation and suction area is limited to the area near the exhaust fan, and the heat dissipation capacity is very limited.
