Description
Technical Field
The utility model belongs to the technical field of the aeronautical manufacturing, a part is related to, concretely relates to pedal lock of aircraft brake disc dismantlement installation.
Background
In the process of disassembling and assembling the aircraft brake disc, the aircraft brake disc disassembling and assembling device needs to be fixed by four angles, and the aircraft brake disc disassembling and assembling device is low in height and small in working space, so that the aircraft brake disc disassembling and assembling device is difficult to directly realize by other tools. For the reasons, a special part is needed to assist in locking and fixing the aircraft brake disc dismounting and mounting device.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model provides an aircraft brake disc dismantles pedal lock of installation realizes fixing aircraft brake disc dismantlement installation device's locking through this pedal lock of operation to operation simple accurate has improved product work efficiency.
The technical proposal of the utility model is that
A pedal lock for dismounting and mounting an aircraft brake disc is of an integrally formed structure and comprises a flanging part 1, an extension rod 2, a sliding groove hole 3, a rotary supporting hole 4 and a lock tooth 5.
The extension rod 2 is an integrated plane structure consisting of a 180-degree arc and a folding rod structure; the arc end part is provided with a rotary supporting hole 4 for connecting a shaft pin of the dismounting and mounting device of the airplane brake disc; a sliding slot hole 3 is arranged at the intersection of the arc and the folding rod structure; and locking teeth 5 with continuous four meshing angles of 60 degrees are arranged on the inner surface of the arc and used for locking hooks on the airplane brake disc dismounting and mounting device. The edge bending part 1 is of a flat plate structure and is perpendicular to the end part of the folding rod structure of the extension rod 2.
The utility model has the advantages that: aircraft brake disc dismantlement installation pedal lock's simple structure is practical, can lock fixed to aircraft brake disc dismantlement installation device comparatively easily, improves product work efficiency.

Fig. 4 is a view B of the present invention.
Fig. 5 is a view C of the present invention.
In the figure: 1, bending edge part; 2, extending rods; 3, sliding slot holes; 4 rotating the supporting hole; 5 locking teeth.
Detailed Description
The present invention will be further described with reference to the following examples and accompanying drawings.
As shown in figure 1, the pedal lock for dismounting and mounting the brake disc of the airplane comprises a crimping part 1, an extension rod 2, a sliding slot hole 3, a rotary supporting hole 4 and a locking tooth 5, wherein the structural components are integrally formed.
Wherein, the extension rod 2 is an integrated plane structure consisting of a 180-degree arc and a folding rod structure; the arc end part is provided with a rotary supporting hole 4 for connecting a shaft pin of the dismounting and mounting device of the airplane brake disc; a sliding slot hole 3 is arranged at the intersection of the arc and the folding rod structure; and locking teeth 5 with continuous four meshing angles of 60 degrees are arranged on the inner surface of the arc and used for locking hooks on the airplane brake disc dismounting and mounting device. The bending part 1 is of a flat plate structure, and the plane of the bending part 1 is vertical to the plane of the extension rod 2.
When the aircraft brake disc is used for dismounting and mounting the pedal lock, firstly, the rotary support hole 4 of the pedal lock is connected to a special shaft pin at the lower part of the aircraft brake disc dismounting and mounting device, an arc-shaped slideway is arranged on the side surface of the sliding slot hole 3, the shaft pin penetrates through the sliding slot hole 3, so that the extension rod 2 rotates around the rotary support hole 4, and meanwhile, the shaft pin on the sliding slot hole 3 slides in the arc-shaped slideway. When the aircraft brake disc dismounting and mounting device is adjusted to a first fixed angle, the bent part 1 is stepped by feet, external force applied from the outside is transmitted to the extension rod 2 through the bent part 1, and the first locking tooth 5 on the extension rod 2 is meshed with the locking hook on the aircraft brake disc dismounting and mounting device, so that the aircraft brake disc dismounting and mounting device is locked, and the angle of a mechanical mechanism is ensured not to be loosened under the condition of non-overload; when the angle of the aircraft brake disc dismounting and mounting device needs to be adjusted, the pedal lock needs to be lifted away from the original position, and then other lock teeth of the extension rod 2 are used for engaging with corresponding lock hooks on the aircraft brake disc dismounting and mounting device.
In summary, the above is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
