Problems solved by technology
[0002] The opening mechanism of the locomotive shutter usually adopts the pull-down structure of the rack. The movement stroke of the blade opening is the same as the movement stroke of the rack. The disadvantages are that the pull-down rack is laborious and the length of the gap at the window frame of the shutter is too large to achieve the sealing of the gap.

Embodiment 1
[0026] Embodiment 1: When opening, the user pushes the opening positioning handle 7 upwards, and the opening positioning handle 7 drives the opening positioning shaft 6 to rotate to open the shutter. At this time, when the ratchet 8 rotates, the block 14 is squeezed up, After the ratchet 8 turns over a tooth degree, the block 14 returns under the elastic force of the spring 13, and stops at an appropriate position as required. The opening positioning rotating shaft 6 can be prevented from rotating when the ratchet 8 and the block 14 cooperate.
Embodiment 2
[0027] Embodiment 2: When closing, the user lifts the locking bolt 11 by hand, since the locking block 14 is connected to the locking bolt 11 through the spring 13, when the locking bolt 11 is lifted, the locking block 14 is also lifted, and the ratchet 8 loses the locking block After being limited by 14, it can rotate freely, and the opening positioning handle 7 is pushed down to reset the shutter.

The invention relates to the technical field of window shutter control devices, in particular to a manual travel control mechanism. The manual travel control mechanism comprises a casing, wherein thecasing comprises a first cover body and a second cover body, a round hole allowing a rotating shaft to pass is formed in the left side of the first cover body, a notch is formed in the right side of the top surface of the first cover body, the notch and the second cover body form a rotating area of an opening positioning handle, an opening positioning rotation shaft connected with the window shutter is arranged in the casing, the opening positioning handle and a ratchet wheel are welded on the opening positioning rotation shaft, the opening positioning handle is arranged in the rotating area,and a positioning pin assembly used for controlling the rotating angle of the ratchet wheel is arranged on the second cover body. The travel mode of the window shutter is transformed from original linear movement into rotating arc movement, an open notch of a window shutter frame is changed into a sealed round hole only allowing the rotation shaft to pass, so that attractive appearance and good sealing performance are realized while function are achieved, and the operation is simple, convenient and light.
Description
technical field [0001] The invention relates to the technical field of shutter control devices, in particular to a manual stroke control mechanism. Background technique [0002] The locomotive shutter opening mechanism usually adopts the pull-down structure of the rack. The movement stroke of the blade opening is the same as that of the rack. The disadvantages are that the pull-down rack is laborious and the length of the gap at the window frame of the shutter is too large to achieve the sealing of the gap. For areas where locomotives are used in harsh environments, problems such as the filtration of air intake in the locomotive interior and high aesthetic requirements need to be resolved urgently. To solve the existing problems, a new structure needs to be designed, that is, a new type of manual stroke control mechanism. Contents of the invention [0003] In order to overcome the shortcomings of the existing shutter control device technology, the present invention provid...
