Detailed Description

The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

The utility model provides a frock of portable driving motor gear box, as shown in fig. 1-5, including first connecting piece 1, second connecting piece 2 and actuating lever 3, first connecting piece 1 is the cylinder, and the both ends of first connecting piece 1 set up not unidimensional mounting hole 11 that is connected with motor gear box pivot respectively, and the one end and the second connecting piece 2 of actuating lever 3 are connected, and first connecting piece 1 can dismantle with second connecting piece 2 and be connected, utilize actuating lever 3 and second connecting piece 2 drive first connecting piece 1 to drive the pivot and rotate. The first connecting piece 1 can be used alone or in combination with the second connecting piece 2 and the driving rod 3. Specifically, when the torque for driving the gear box to rotate is smaller, the assembly hole 11 of the first connecting piece 1 can be directly connected with the output shaft, and a maintainer holds the first connecting piece 1 to directly drive the output shaft to rotate so as to drive the gear box to operate, and further search for abnormal sound points. When the required torque is larger, the first connecting piece 1, the second connecting piece 2 and the driving rod 3 are matched, namely, the force arm is increased through the driving rod, so that the force required by a maintainer to drive the reduction gearbox is reduced.

In an embodiment, as shown in fig. 1-5, the side wall of the first connecting piece 1 is provided with a plurality of connecting grooves 12 circumferentially at intervals, the second connecting piece 2 is provided with a through hole which penetrates through the first connecting piece axially and allows the first connecting piece to pass through, and a connecting key 21 matched with the connecting grooves 12 is radially protruding in the through hole. In use, the second connector 2 is sleeved on the first connector 1, and the connecting key 21 is placed in the connecting groove 12, so as to realize the assembly of the first connector 1 and the second connector 2.

In one embodiment, as shown in fig. 1 to 5, a first connection hole 22 is provided on a sidewall of the second connection member 2, and one end of the driving rod 3 is detachably connected to the first connection hole 22. Specifically, the inner wall of the first connecting hole 22 is provided with an internal thread, one end of the driving rod 3 is provided with an external thread matched with the internal thread, and then the driving rod 3 is in threaded connection with the first connecting hole 22.

In order to facilitate the storage of the driving rod 3, as shown in fig. 1-5, a second connecting hole 23 is further arranged on the side wall of the second connecting piece 2, the first connecting hole 22 and the second connecting hole 23 are on the same axis, and the diameter of the second connecting hole 23 is larger than that of the driving rod 3; i.e. the driving rod 3 can pass through the second connection hole 23. When the drive rod 3 is stored, the drive rod 3 is separated from the second connecting piece 2, and then one end of the drive rod 3 provided with external threads passes through the second connecting hole 23 and is connected with the first connecting hole 22; this completes the storage of the drive lever 3.

When the utility model is used, as shown in fig. 1-5, if the force requirement for driving the gear box is small, only the first connecting piece 1 is required to be connected with the output shaft, and a maintenance person can hold the first connecting piece 1; the teeth formed by the adjacent connecting grooves 12 on the first connecting piece 1 prevent slipping when held by a serviceman. If the force demand of the drive gear box is large, after the drive rod 3 is assembled with the second connecting piece 2, the second connecting piece 2 is assembled with the first connecting piece 1, and the drive force arm is increased through the drive rod 3, so that maintenance personnel can easily drive the gear box to rotate. The starting position of the driving rod 3 can be adjusted by matching the connecting key 21 with the connecting groove 12, so that the force application of maintenance personnel is facilitated.

The foregoing is merely a preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model; modifications and equivalent substitutions are intended to be included in the scope of the claims without departing from the spirit and scope of the present utility model.
