Description

Water-proof ventilation type locomotive limit ring device controls casing

Technical field

The utility model relates to a kind of water-proof ventilation type locomotive limit ring device and controls casing, is assemblied in vent external.

Background technology

At present, vent external product is easily damaged by object strikes such as slungshot, maintenance blunts, and vent external product hermetically-sealed construction many employings totally enclosed, for needing the product carrying out circulating air heat radiation, heat radiation cannot be realized.

Summary of the invention

Technical problem to be solved in the utility model is the defect overcoming prior art, a kind of water-proof ventilation type locomotive is provided to limit ring device to control casing, it can fully dispel the heat, and rainwater can be prevented to be splashed in cabinets cavity, ensures that the locomotive limit ring device in it normally works.

In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of water-proof ventilation type locomotive limit ring device controls casing, it comprises body, the end of the sidewall of body has the heat dissipation ventilation hole leading to its inner chamber, the outside of the sidewall of body, near heat dissipation ventilation hole, position is provided with weather bar, and this weather bar is positioned at the top in heat dissipation ventilation hole to prevent rainwater to be splashed to inner chamber by heat dissipation ventilation hole.

Further provide a kind of concrete structure of body, described body comprises:

Drain pan, described heat dissipation ventilation hole is arranged on the end of the sidewall of drain pan, and described weather bar is arranged on the outside of the sidewall of drain pan;

Upper cover, this upper cover is connected by screw on drain pan.

Further in order to enable this casing dust-proof, the screw between described drain pan and upper cover is provided with packing seal, and the both sides of sealing pad are connected in drain pan and upper cover respectively, are also provided with packing seal between described weather bar and drain pan.

The concrete shape further providing a kind of heat dissipation ventilation hole fully dispels the heat to make this casing, and described heat dissipation ventilation hole is waist-shaped hole.

The concrete structure further providing a kind of weather bar makes it meet rainwater can be prevented to be splashed in cabinets cavity, described weather bar is L-type structure, and one of weather bar branches into adapter plate, and another branches into waterproof board, and weather bar is connected with body by adapter plate.

After have employed technique scheme, the heat dissipation ventilation hole leading to its inner chamber of the end setting of the sidewall of body, for casing outside air heat loss through convection, weather bar can prevent rainwater to be directly splashed to box house by heat dissipation ventilation hole, the packing seal added between weather bar and drain pan and the packing seal between upper cover and drain pan, can meet dust reduction capability, and this casing inherently has explosion prevention function, many-side ensure that the locomotive limit ring device in it normally works.

Detailed description of the invention

In order to make content of the present utility model more easily be clearly understood, below according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail.

As shown in Figures 1 to 3, a kind of water-proof ventilation type locomotive limit ring device controls casing, it comprises body, the end of the sidewall of body has the heat dissipation ventilation hole 1 leading to its inner chamber, the outside of the sidewall of body, near heat dissipation ventilation hole 1, position is provided with weather bar 2, and this weather bar 2 is positioned at the top in heat dissipation ventilation hole 1 to prevent rainwater to be splashed to inner chamber by heat dissipation ventilation hole 1.The quantity in heat dissipation ventilation hole 1 is not limit, and the present embodiment is six, every side.

As shown in Figure 1, 2, body comprises:

Drain pan 3, heat dissipation ventilation hole 1 is arranged on the end of the sidewall of drain pan 3, and weather bar 2 is arranged on the outside of the sidewall of drain pan 3;

Upper cover 4, this upper cover 4 is connected on drain pan 3 by screw 34.

As shown in Figure 3, the screw 34 between drain pan 3 and upper cover 4 is provided with packing seal 5, and the both sides of sealing pad 5 are connected in drain pan 3 and upper cover 4 respectively, are also provided with packing seal 5 between weather bar 2 and drain pan 3.

As shown in Figure 1, heat dissipation ventilation hole 1 is waist-shaped hole, but is not limited thereto.

As shown in Figure 3, weather bar 2 is L-type structure, and one of weather bar 2 branches into adapter plate 21, and another branches into waterproof board 22, and weather bar 2 is connected with body by adapter plate 21.

Principle of work of the present utility model is as follows:

The heat dissipation ventilation hole 1 leading to its inner chamber of the end setting of the sidewall of body, for casing outside air heat loss through convection, weather bar 2 can prevent rainwater to be directly splashed to box house by heat dissipation ventilation hole 1, the packing seal 5 added between weather bar 2 and drain pan 3 and the packing seal 5 between upper cover 4 and drain pan 3, dust reduction capability can be met, and this casing inherently has explosion prevention function, many-side ensure that the locomotive limit ring device in it normally works.

Above-described specific embodiment; technical matters, technical scheme and beneficial effect that the utility model solves are further described; be understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
