Abstract
The utility model belongs to the technical field of airplane connecting piece design and particularly relates to a bolt shaft with split pins installed in two directions. The bolt shaft with the split pins installed in the two directions is characterized in that threads are arranged on the end portion of the bolt shaft, two split pin holes which are matched with notches of hexagon slotted nuts are formed in the end portion of the bolt shaft, and hole axes of the two split pin holes are located on the same plane and cross with each other. The bolt shaft with the split pins installed in the two directions is widely applicable to the installation of split pins of helicopters and fixed-wing planes, the structure and installation are simple, maintenance is convenient, and the bolt shaft is easy to obtain. According to the bolt shaft with the split pins installed in the two directions, due to the fact that the split pin holes cross with each other, when the split pin hole in the vertical direction is blocked, it still can be guaranteed that the split pin hole in the horizontal direction is exposed, and then the corresponding split pin can be inserted into the split pin hole in the horizontal direction.
Description
Technical field
Aircraft stud connector design technical field of the present invention, particularly designs a kind of two bolt axis to construction opening pin.
Background technique
In aircraft flight control system, the locking of bolt conventionally adopts and play cotter pin in the cotter-pin hold of bolt head, and the hexagon slotted nut rotation that utilizes cotter pin to stop to coordinate with bolt, to play the effect of screw retention.Hexagon slotted nut is standard piece, on its six outer side surfaces, all respectively has a groove, and the groove on two relative faces is coaxial, and the angle between adjacent fluted shaft is 60 degree.
Bolt for construction opening pin on existing domestic helicopter and fixed wing machine has a cotter-pin hold, if it is inaccurate that in installation process, hexagon slotted nut screw-down torque is determined power, in six grooves of hexagon slotted nut, the cotter-pin hold of neither one and bolt connects, cotter-pin hold has just been blocked by hexagon slotted nut, cannot insert, cause cotter pin to install, bolt cannot lock.Now, can only cotter pin be inserted in cotter-pin hold by readjusting the relative position of bolt axis and hexagonal self-locking nut, readjust and can cause the position of hexagonal self-locking nut can not meet installation requirement.
Summary of the invention
The technical problem to be solved in the present invention:
The utility model is in bolt axis, to add a cotter-pin hold, forms the cotter-pin hold of criss-crossing, when a direction cannot construction opening pin, can install from another one hole, has both reduced structure weight, maintains easily again.The utility model is just for above-mentioned deficiency of the prior art, and the mounting type of a kind of cotter pin of proposition, when construction opening pin, is selectively used cotter-pin hold to carry out the fastening of screw bolt and nut.Its objective is and be convenient to construction opening pin in producing and using.
Technological scheme of the present invention:
The technical solution of the utility model is: for the bolt axis that hexagon slotted nut and cotter pin are installed, form due to hexagon slotted nut groove, in former cotter-pin hold position, 90-degree rotation increases by a cotter-pin hold, make when hexagon slotted nut rotates in bolt axis, can can expose cotter-pin hold all the time, and then construction opening pin easily.
Two bolt axis to construction opening pin, there is screw thread bolt axis 1 end, and is provided with two cotter-pin holds that coordinate with the fluting of hexagon slotted nut 4, and two cotter-pin hold hole axles are in a plane, and criss-crossing.
Beneficial effect of the present invention:
The utility model is widely used in the cotter pin of helicopter and fixed wing machine and installs, and structure and installation are simple, easy to maintenance, is easy to realize.This bolt axis 1, because cotter-pin hold becomes criss-crossing, the cotter-pin hold of Vertical direction is blocked while making in as Fig. 1, still can guarantee that the cotter-pin hold of substantially horizontal exposes, and cotter pin 3 can be inserted.
Accompanying drawing explanation
Fig. 1 is bolt axis construction opening pin schematic diagram; 1 is bolt axis, and 2 is cotter pin, and 3 is cotter pin, and 4 is hexagon slotted nut,
Fig. 2 is conventional hexagon slotted nut;
Fig. 3 bolt axis schematic diagram, 5 is cotter-pin hold.
Embodiment
Below in conjunction with drawings and Examples, the present invention is explained as follows:
At Fig. 3, can see, there is screw thread bolt axis 1 end, and is provided with two cotter-pin holds that coordinate with hexagon slotted nut 4 flutings, and two cotter-pin hold hole axles are in a plane, and criss-crossing.There is screw thread bolt axis 1 end, and is provided with 5, two cotter-pin hold hole axles of two cotter-pin holds in a plane, and criss-crossing.Its relative position is in a plane, and criss-crossing.Normally used bolt axis only has a cotter-pin hold, if after the first-class screw-down torque of hexagon slotted nut 4 just when position shown in Fig. 1, just the corresponding cotter-pin hold of cotter pin 2 has been blocked by hexagon slotted nut 4, cannot insert.Can only with the relative position of hexagon slotted nut 4, cotter pin 2 can be inserted in cotter-pin hold by readjusting bolt axis 1.And for the design's bolt axis 1, due to 5 one-tenth criss-crossings of cotter-pin hold, the cotter-pin hold of Vertical direction is blocked while making in as Fig. 1, still can guarantee that the cotter-pin hold of substantially horizontal exposes, and cotter pin 3 can be inserted.
