Detailed Description

The following is further detailed by way of specific embodiments:

reference numerals in the drawings of the specification include: the pull cable fixing device comprises a panel seat 1, a pull cable sleeve 21, a pull cable steel wire rope 22, a pull cable fixing plate 3, a mounting hole 41, a spring 42, a steel ball 43, a swing rod 5, a pressing plate 6, a handle 7, a switch rotating shaft 8, a cam 9, a rectangular hole 91, a limiting block 10 and a flameout switch 11.

The embodiment is basically as shown in the attached figure 1: the utility model provides a choke valve control combination mechanism, includes panel seat 1 for open and close the cable combination of choke valve, the cable combination includes cable wire rope 22 and cable sleeve pipe 21, cable sleeve pipe 21's one end and panel seat 1 quiet connection, specifically, has seted up spacing hole on panel seat 1, and the joint has cable fixed plate 3 in spacing hole department, and cable fixed plate 3 passes through the bolt and is connected fixedly with panel seat 1, and cable sleeve pipe 21 joint is in the draw-in groove on cable fixed plate 3. The panel base 1 is connected with a fuel switch, a switch rotating shaft 8 of the fuel switch is statically connected with a cam 9 matched with the flameout switch 11, specifically, the cross section of the switch rotating shaft 8 is rectangular, a rectangular hole 91 matched with the switch rotating shaft 8 is formed in the cam 9, and the cam 9 is sleeved on the switch rotating shaft 8 through the rectangular hole 91, so that the cam 9 and the switch rotating shaft 8 synchronously rotate, and the flameout switch 11 can be controlled to be turned on and off through the rotation of the cam 9. Cam 9 is provided with the gear structure towards between fuel switch's one side and the panel seat 1, the gear structure is including setting up the gear spout on cam 9, the gear spout includes quenching shelves recess along cam 9's edge in proper order, close oily shelves recess, open oily shelves recess, close the air door recess, the gear structure is still including setting up the stop gear on panel seat 1, stop gear is including setting up mounting hole 41 on panel seat 1, be provided with spring 42 and steel ball 43 in the mounting hole 41, steel ball 43 keeps the contact state with the gear spout under spring 42's effect. The side of the cam 9 facing away from the fuel switch is integrally formed with a stopper 10.

The switch rotating shaft 8 is rotatably connected with a swing rod 5, and one end of the swing rod 5, which is far away from the switch rotating shaft 8, is connected with a stay cable wire rope 22. The swing rod 5 is attached to the cam 9, and a limiting block 10 on the cam 9 is in clutch fit with the swing rod 5. In order to increase the stability of the swing rod 5, a pressing plate 6 is sleeved on the switch rotating shaft 8, and the pressing plate 6 is attached to one side, far away from the cam 9, of the swing rod 5. One side of the pressing plate 6, which is far away from the swing rod 5, is provided with a handle 7, the end part of the handle 7 is provided with a rectangular counter bore matched with the switch rotating shaft 8, and the handle 7 is sleeved on the switch rotating shaft 8 through the rectangular counter bore and is connected and fixed through screws.

The specific implementation process is as follows: initially (as shown in fig. 2), the cam 9 is in contact with the key-off switch 11, and the steel ball 43 of the shift structure is located in the key-off groove, and the damper is in an open state. When the air door needs to be closed to start machinery, the handle 7 rotates clockwise to drive the switch rotating shaft 8 of the fuel switch to rotate, the switch rotating shaft 8 drives the cam 9 to rotate clockwise, and therefore the steel balls 43 of the gear structure sequentially pass through the oil-cut gear groove and the oil-cut gear groove, until the limiting block 10 on the cam 9 contacts with the swing rod 5 and drives the swing rod 5 to rotate clockwise, when the swing rod 5 rotates clockwise for a certain angle, the steel balls 43 of the gear structure contact with the air-cut gear groove, and in the process of clockwise swinging of the swing rod 5, the swing rod 5 drives the air door to move gradually to a closed state through the stay cable steel wire rope 22 (as shown in figure 3). After the starting of the machinery is successful, the handle 7 is rotated anticlockwise to enable the cam 9 to rotate anticlockwise to an oil opening gear or an oil closing gear, and the swing rod 5 also rotates anticlockwise under the action of the pulling force of the stay cable steel wire rope 22 to enable the air door to be in an opening state (as shown in fig. 4).
