Problems solved by technology
[0005] Although the above two devices can realize the automatic control of shutters, their transmission mechanism and reset mechanism all rely on springs, but the service life of the springs is short and the use is not reliable. will be reduced, and the force to push the sheet and reset the sheet will be insufficient, thus affecting normal use
[0006] In addition, when the traditional leaf is installed between the window frame, the pin and the fastener of the leaf use the same part, that is, the pin is directly fixed on the window frame through the nut, and the rotating shaft of the leaf and the pin Rotate the connection, when the blade rotates, the pin shaft will also be affected by it, after a period of use, the pin shaft will loosen, and even the pin shaft will fall off

Embodiment Construction
[0028] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0029] Such as Figure 1 to Figure 3 As shown, the roof shutters for the vehicle:
[0030] Including the window frame 1, the leaf 2 and the linkage device 3, because the roof shutters for vehicles have a large area, a beam 5 is also set in the middle of the window frame 1 to play a role of reinforcement, and at the same time it is used to fix the linkage device 3. In order to avoid deformation of the leaf 2 caused by the excessive length of the single leaf 2, the leaf 2 is divided into two groups, which are arranged on both sides of the linkage device 3 respectively.
[0031] Such as Figure 4 The two groups of sheets 2 shown have an included angle 19 between each other, and the included angle 19 can generally be set to about 170°, so that the middle position is slightly higher than the two sides, so that the rainwater from the outside can be ...

The invention relates to a vehicle top shutter comprising a window frame, blades and a linkage device, wherein each blade is provided with a long straight blade rotating shaft; the blade rotating shaft and the window frame are rotatably connected by a mounting device; the mounting device comprises a layer of mounting plate fixedly connected with the window frame; the mounting plate is provided with a step hole relative to the position of each blade rotating shaft; pin shafts with bosses are fixed in the step holes; one end of each blade rotating shaft is sleeved on the pin shafts; the middle part of the window frame is provided with a beam; the linkage device is fixed on the beam; the blades are arranged at both sides of the linkage device; the linkage device comprises connecting rods arranged at both sides, pin shafts connected with the connecting rods of both sides, push rod heads sleeved on the pin shafts, power mechanisms connected with the push rod heads and rotating arms arranged corresponding to the blades. The vehicle top shutter has simple structure, long service life, stable and reliable work and good anti-loosening property and can drive the blades to the opened and closed by pushing push rods completely by the reciprocating movement of the power mechanisms.
Description
technical field [0001] The invention relates to a louver, in particular to a top louver installed above a vehicle, which belongs to the accessory equipment of the vehicle. Background technique [0002] A cooling device for cooling the transmission oil and fuel in the diesel engine is installed above the roof of the locomotive of the rail vehicle. Equipped with shutters. At present, the top shutters used in the cooling devices of domestic rail vehicle locomotives generally cannot be controlled automatically, but the wind generated by the large fan in the cooling device is used to forcibly blow the slats open. When the large fan stops working, rely on its The blades are closed by their own gravity. Although this structure is simple, it produces certain resistance to the work of the large fan, which is not conducive to the work of the large fan, and the blades are easily damaged under long-term impact. At the same time, because the diameter of the large fan is larger, the tot...
