Abstract
The utility model discloses an external air ventilation opening device for an integrated bullet train compartment. The external air ventilation opening device is composed of a fixed connection outer folding edge, a ventilation ring opening with an inner convex edge, a ventilation channel, a connection screw hole, an outer connection folding edge, a connection inner folding edge, a part body and an inner inclined edge. The part body of the external air ventilation opening device is casted by aluminum alloy in one time, and then corners and surfaces of the part body are milled and machined flat through a milling machine. The external air ventilation opening device has the advantages of being good in integrated connection and high in strength of the part body. Thus, the defect that the welding portion of the part body is prone to crack due to high speed running and vibration of a bullet train is overcome. Furthermore, safe running of the bullet train is guaranteed.
Description
Technical field
The present invention relates to the technical field of motor-car accessory, especially refer to integrated motor train compartment extraneous air air vent.
Background technology
Along with the development of Technology Times, motor-car has entered among the daily life, and in neoteric and modern power concentration motor train unit, motor-car is more near the locomotive role in the conventional train, and in China, speed per hour is called " motor train unit " up to 250km or above train.Motor-car has delelivered payload capability and the conveying efficiency that improves passenger and article, therefore is subject to the attention of many countries and progressively develops into the transportation means that generally uses.At present mostly motor train compartment extraneous air air vent is to adopt rolled-up stock to be welded to form, and in the high-speed cruising of motor-car, exists that weld zone easily produces the defectives such as crack under high-speed cruising and vibrations, brings potential potential safety hazard for the operation of motor-car.
Summary of the invention
The integrated motor train compartment extraneous air of the utility model air vent can solve the deficiency of above-mentioned technology, adopts the part body of disposable casting aluminum alloy, can realize the purpose of high-strength integrated breather pipe component parts.
To achieve these goals, technical solution of the present invention is: integrated motor train compartment extraneous air air vent comprises by the outer flanging of captive joint, the draught ring mouth with inner raised edge, air flue, connecting screw hole, outer connection flanging, the interior flanging of connection, part body, interior hypotenuse and forming; Adopt the part body of the disposable casting aluminum alloy of casting method, part body top arranges with the outer flanging of the captive joint in connecting screw hole and outer connection flanging, bottom flanging in the connection is set, part body inside middle arranges the draught ring mouth of an astragal inner raised edge, the center is air flue, part body inside middle is interior hypotenuse on one side, it is whole to adopt milling machine that part body corner and plane milling are scabbled, i.e. integrated motor train compartment extraneous air air vent.
The beneficial effects of the utility model are: adopt the disposable casting of aluminum alloy compartment extraneous air air vent, it is good to have integrated connection, the advantage that part body intensity is high, can avoid producing the defective in crack because of the high-speed cruising of motor-car and vibrations part body weld zone, for the safe operation of motor-car provides guarantee.
Description of drawings
Below in conjunction with the drawings and specific embodiments utility model is further described.
Accompanying drawing 1 integrated motor train compartment extraneous air air vent scheme drawing;
Accompanying drawing 2 integrated motor train compartment extraneous air air vent schematic side view.
Among the figure: 1, the outer flanging of captive joint, 2, with the draught ring mouth of inner raised edge, 3, air flue, 4, the connecting screw hole, 5, outer connection flanging, 6, connect in flanging, 7, the part body, 8, interior hypotenuse.
The specific embodiment
Shown in accompanying drawing, integrated motor train compartment extraneous air air vent comprises by the outer flanging 1 of captive joint, the draught ring mouth 2 with inner raised edge, air flue 3, connecting screw hole 4, outer connection flanging 5, the interior flanging 6 of connection, part body 7, interior hypotenuse 8 and forming; Adopt the part body 7 of the disposable casting aluminum alloy of casting method, part body 7 tops arrange with the outer flanging 1 of the captive joint in connecting screw hole 4 and outer connection flanging 5, bottom flanging 6 in the connection are set, part body 7 inside middle arrange the draught ring mouth 2 of an astragal inner raised edge, the center is air flue 3, part body 7 inside middle are interior hypotenuse 8 on one side, it is whole to adopt milling machine that part body corner and plane milling are scabbled, i.e. integrated motor train compartment extraneous air air vent.
The above; embodiment only is that preferred implementation of the present invention is described; be not that scope of the present invention is limited; under the prerequisite of the spirit that does not break away from the technology of the present invention; various distortion and improvement that this area engineering staff make technical scheme of the present invention all should fall in the definite protection domain of claims of the present invention.
