Abstract
The utility model belongs to aviation field, more particularly to a kind of elevating mechanism adjusted for aircraft bracket.Elevating mechanism belongs to a kind of transmission mechanism, drives screw rod to move up and down by nut rotation, but the rotation of nut overtravel can cause screw rod to be come off with nut, and certain potential safety hazard can be brought in use.Elevating mechanism of the present utility model, is fixedly connected with outer barrel on base, and inner cylinder is connected by bolt with outer barrel in barrel, and the inner cylinder has part annular configuration, wherein with groove, nut has the boss combined with the groove；Screw rod is connected with the nut thread, and limiting plate is fixedly connected with the bottom for passing nut and inner cylinder.Nut rotates in the groove of inner cylinder, drives screw rod to move up and down, screw rod lower end be connected with limiting plate, and limiting plate restriction screw rod is elevated minimum with highest stroke, so as to prevent screw rod from being come off with nut.
Description
Technical field
The utility model belongs to aviation field, more particularly to a kind of elevating mechanism adjusted for aircraft bracket.
Background technology
Elevating mechanism belongs to a kind of transmission mechanism, drives screw rod to move up and down by nut rotation, but nut overtravel is revolved
The change of team causes screw rod to be come off with nut, and certain potential safety hazard can be brought in use.
Utility model content
The purpose of this utility model causes the problem of screw rod comes off with nut aiming at the rotation of nut overtravel, and there is provided one
Plant the transmission mechanism for limiting screw rod lifting travel.
The utility model solves the technical scheme that its technical problem used：A kind of lifting adjusted for aircraft bracket
Mechanism, is fixedly connected with outer barrel on base, and inner cylinder is connected by bolt with outer barrel in barrel, and the inner cylinder has part-toroidal
Structure, wherein with groove, nut has the boss combined with the groove；Screw rod is connected with the nut thread, is being passed
The bottom of nut and inner cylinder is fixedly connected with limiting plate.
The bottom of the screw rod and the spacing plate weld are bolted, and limiting plate is limited at outer barrel
Between bottom and the bottom of inner cylinder.
The upper end of the screw rod is connected with the aircraft bracket.
Remarkable result of the present utility model is：Nut rotates in the groove of inner cylinder, drives screw rod to move up and down, under screw rod
End be connected with limiting plate, and limiting plate restriction screw rod is elevated minimum with highest stroke, so as to prevent screw rod from being come off with nut.
Brief description of the drawings
Fig. 1 is the assembling exploded perspective view of the utility model elevating mechanism；
Fig. 2 is the oblique view of the utility model elevating mechanism；
Fig. 3 is the front view of the utility model elevating mechanism；
Fig. 4 is the left view of the utility model elevating mechanism.
Embodiment
A kind of elevating mechanism adjusted for aircraft bracket includes base 1, outer barrel 2, bolt 3, inner cylinder 4, nut 5, spiral shell
Bar 6, limiting plate 7, the base 1 of described elevating mechanism are fixedly connected with outer barrel 2, and outer barrel 2 passes through bolt with inner cylinder 4 on barrel
3 are spirally connected, and nut 5 has boss, and embedded in the groove of the part annular configuration of inner cylinder 4, nut 5 is spirally connected with screw rod 6, spacing
Plate 7 is fixedly connected with the bottom of screw rod 6.Nut 5 rotates in the groove of inner cylinder 4, so as to drive screw rod 6 to move up and down；When spacing
When plate 7 is moved down into the bottom of outer barrel 2, screw rod 6 can not continue to move downward, when limiting plate 7 is moved upwards up to and the bottom of inner cylinder 4
When portion is contacted, screw rod 6 can not be continued up, so as to reach the highest for limiting screw rod 6 and the purpose of minimum stroke.
Embodiment described above only expresses embodiment of the present utility model, and it describes more specific and detailed, but simultaneously
Therefore the limitation to the utility model the scope of the claims can not be interpreted as.It should be pointed out that for the ordinary skill of this area
For personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these belong to this
The protection domain of utility model.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
