Abstract
Disclosed is an anti-falling device for a throttle control mechanism of a water-heating fan heater of an automobile. An inverted hook is designed at the top of a control level shift pin of the anti-falling device, and the control lever shift pin and the inverted hook form a T shape. By means of the anti-falling device, the problem that the throttle control mechanism fails due to the fact that the control level shift pin falls from a rocker arm shift fork groove during transport of the fan heater of the automobile and operation of the throttle control mechanism can be effectively solved. The anti-falling device can be widely applied to design of the throttle control mechanism of the fan heater of the automobile.
Description
One, technical field
The utility model relates to a kind of Water heating for vehicle formula fan heater air door steering unit, particularly a kind of Water heating for vehicle formula fan heater air door steering unit anti-drop device.
Two, background technology
Each air door rocking arm running of Water heating for vehicle formula heater unit is at present mainly controlled by the joystick finger, prevent the joystick finger deviate from air door rocking arm fork slot mainly by plastic washer to the thrust of joystick rotating shaft place, when the width between centers of joystick finger and joystick rotating shaft is excessive, joystick shaft is big to amount of deflection, in the case, when the external force that heater unit is carried, steering unit running impact etc. causes is done the time spent, the joystick finger is easy to air door rocking arm fork slot, cause the air door steering unit to lose efficacy, as steering unit clamping stagnation, gear confusion etc.
Three, summary of the invention
The purpose of this utility model provides a kind of Water heating for vehicle formula fan heater air door steering unit anti-drop device, it can effectively solve automotive fan heater in carrying, air door steering unit operation process, the joystick finger is deviate from the rocking arm fork slot, the problem that causes the air door steering unit to lose efficacy.
The technical scheme that the utility model adopts is: a kind of Water heating for vehicle formula fan heater air door steering unit anti-drop device, comprise air door, air door rocking arm, joystick, plastic washer, rotating shaft, blowing control panel, casing, joystick finger and air door rocking arm fork slot, described air door, plastic washer, blowing control panel are contained on the casing; The air door rocking arm is contained on the air door; Control stalk is contained in the rotating shaft, and rotating shaft and casing are the integrated through injection molding part, and the joystick finger on the joystick is located in the air door rocking arm fork slot, and joystick finger top design has overhead kick.
Described joystick finger and overhead kick form " ┻ " shape.The overhead kick width is more smaller than fork slot width, is convenient to the finger fork slot of packing into.Overhead kick and air door rocking arm surface forms axial constraint, prevents that the joystick finger from deviating from fork slot.
Outstanding effect of the present utility model is:
1, owing to be that joystick in the Water heating for vehicle formula fan heater air door steering unit increases axial constraint newly, make joystick shaft to being subjected to two-way constraint, can effectively solve automotive fan heater in carrying, air door steering unit operation process, the joystick finger is deviate from the rocking arm fork slot, the problem that causes the air door steering unit to lose efficacy.
2, connect more reliable than conventional joystick finger.
Four, description of drawings
Fig. 1 is the assembling scheme drawing of Water heating for vehicle formula fan heater air door steering unit anti-drop device described in the utility model.
Fig. 2 is the overhead kick structural representation of Water heating for vehicle formula fan heater air door steering unit anti-drop device described in the utility model.
Five, the specific embodiment
Below in conjunction with drawings and Examples technology formation of the present utility model and principle of work are described in further detail.
As depicted in figs. 1 and 2, described Water heating for vehicle formula fan heater air door steering unit anti-drop device comprises air door 1, air door rocking arm 2, joystick 3, plastic washer 4, rotating shaft 5, blowing control panel 6, casing 7, joystick finger 8 and air door rocking arm fork slot 9.Described air door 1, plastic washer 4, blowing control panel 6 are contained on the casing 7; Air door rocking arm 2 is contained on the air door 1; Control stalk 3 is contained in the rotating shaft 5, and rotating shaft 5 is the integrated through injection molding part with casing 7.
During work, 5 rotations around the shaft of blowing control panel 6 control joysticks 3; During joystick 3 rotations, joystick finger 8 is stirred 2 swings of air door rocking arm by air door rocking arm fork slot 9, and air door 1 is flush fit with air door rocking arm 2, and air door 1 is with 2 swings of air door rocking arm.
Water heating for vehicle formula fan heater air door steering unit anti-drop device principle of work described in the utility model:
By 5 rotations around the shaft of blowing control panel 6 control joysticks 3, control the pivot angle size of air door rocking arms then by the finger 8 on the joystick 3.Joystick finger 8 on the joystick 3 is in air door rocking arm fork slot 9, and in the corner that joystick is carried out, the overhead kick on the joystick finger 8 and air door rocker plate face formation axial constraint prevent that effectively it from deviating from air door rocking arm fork slot 9.
