Utility model content
The purpose of this utility model is to provide the dismantling device of Boeing-737 type aircraft main landing gear throttling stay pipe nut, this dismantling device structure is simple, the dismounting of Boeing-737 type aircraft main landing gear throttling stay pipe nut can be realized quickly and easily, increase work efficiency.
This purpose of the present utility model realizes by the following technical solutions: the dismantling device of Boeing-737 type aircraft main landing gear throttling stay pipe nut, described nut has nut, nut edge evenly offers four breach, it is characterized in that: described dismantling device is round barrel cover, round barrel cover has circular cylinder body and top cover, the inwall of cylindrical shell is provided with four location convex tendons along the direction of Barrel alignment, article four, locate convex tendon evenly to arrange, article four, locate four breach that the setting position of convex tendon and described nut offer suitable, be meshed in described round barrel cover four breach that four location convex tendons are inserted into nut in use, round barrel cover can rotate under external force and drive nut synchronous axial system, thus realize dismounting and the installation of nut.
In the utility model, the top cover of described round barrel cover offers square driving hole, for supplying torque spanner plug-in mounting during dismounting nut.
In the utility model, described driving hole is opened in top cap central place.
In the utility model, described cylindrical shell and top cover one-body molded.
Compared with prior art, the utility model dismantling device has following remarkable result:
(1) technological gap that genuine handbook does not provide dismantling device filled up by the utility model dismantling device.
(2) the utility model dismantling device and nut four grooves are meshed, and avoid damaging nut, can effectively increase work efficiency when dismounting nut simultaneously.
(3) the utility model dismantling device central aperture, coordinates torque spanner to use time convenient for assembly.

Detailed description of the invention
Adopt the structure chart of the Boeing-737 type aircraft main landing gear throttling stay pipe nut of the utility model dismantling device dismounting identical with existing nut, all as shown in Figure 1 and Figure 2, this nut 1 has nut 11, and nut 11 edge evenly offers four breach 11a.
The structure chart of the dismantling device of the utility model Boeing-737 type aircraft main landing gear throttling stay pipe nut is as shown in Fig. 3 to Fig. 7, dismantling device is round barrel cover 2, round barrel cover 2 has circular cylinder body 21 and top cover 22, cylindrical shell 21 and top cover 22 one-body molded, the inwall of cylindrical shell 21 is provided with four location convex tendon 21a along the direction of cylindrical shell 21 center line, article four, locate convex tendon 21a evenly to arrange, angle between location convex tendon 21a adjacent is between two 90 °, article four, locate four breach 11a that the setting position of convex tendon 21a and nut 1 offer suitable, be meshed in round barrel cover 2 four breach 11a that four location convex tendon 21a are inserted into nut 1 in use, round barrel cover 2 can rotate under external force and drive nut 1 synchronous axial system, thus realize dismounting and the installation of nut 1.
In the present embodiment, top cover 22 center of round barrel cover 2 offers square driving hole 22a, for supplying torque spanner plug-in mounting during dismounting nut 1.Set up driving hole 22a, make to carry out dismounting by conventional torque spanner when dismounting nut 1.If there is no driving hole 22a, also dismounting can be carried out with the spanner of routine.
The dismantling device of the present embodiment carries out dismounting mainly for Boeing-737 type aircraft main landing gear throttling stay pipe nut, and wherein Boeing-737 type aircraft comprises Boeing-737/300-500 type aircraft.Certainly, the aircraft main landing gear throttling stay pipe nut of this dismantling device to other types is also suitable for, or is also suitable for after slightly improving.
Dismantling device of the present utility model in use, be meshed in four the breach 11a being inserted into nut 1 by four location convex tendon 21a, torque spanner inserts in driving hole 22a, rotating torque spanner, dismantling device rotates under torque spanner effect, and drive nut 1 synchronous axial system, with the dismounting of existing nut 1 and installation.
Above-described embodiment of the present utility model is not the restriction to the utility model protection domain; embodiment of the present utility model is not limited thereto; all this kind is according to foregoing of the present utility model; according to ordinary technical knowledge and the customary means of this area; do not departing under the utility model above-mentioned basic fundamental thought prerequisite; to the amendment of other various ways that the utility model said structure is made, replacement or change, all should drop within protection domain of the present utility model.
