Description
Technical Field
The utility model relates to a motor tricycle's technical field, more specifically relates to a locking mechanism.
Background
The existing motorcycle usually adopts a two-wheel or three-wheel structure, the front wheels are the steering mechanism of the motorcycle, the driver changes the advancing direction of the motorcycle by operating and rotating a handle, and the motorcycle with the three-wheel structure is easier to be mastered by the driver than the motorcycle with the two-wheel structure. The traditional motor tricycle generally adopts a structure that a single wheel is arranged in front of the tricycle and two wheels are arranged behind the tricycle, the positions of the two wheels on the rear side are fixed, a shock absorber is arranged at the part below a seat cushion, and jolts and vibrations of the tricycle during running are buffered through the shock absorber so as to improve the driving comfort. However, the tricycle has poor anti-roll capability and turning capability in the running process, the tricycle rolls when the speed is slightly high, the rollover accident is easy to happen, and meanwhile, the trafficability of the tricycle on a bumpy road surface is poor. In the prior art, a tricycle with a rear wheel capable of swinging according to a running road surface also appears, but the existing tricycle is relatively complex in support structure, troublesome in locking operation and easy to overturn when parked; how to lock the tricycle conveniently and quickly under the conditions of parking and no need of swinging for running is also an urgent problem to be solved in the prior art.
Therefore, there is a need in the art for a solution for efficiently locking a three-wheeled rocking vehicle.
SUMMERY OF THE UTILITY MODEL
Not enough to above-mentioned prior art, the utility model provides a locking mechanism.
In order to achieve the above purpose, the utility model discloses a following technical scheme realizes:
a locking mechanism comprises a lock pin, a lock pin outer sleeve, a lock pin cap and a lock pin outer sleeve, wherein the lock pin cap and the lock pin outer sleeve are mutually buckled, the lock pin outer sleeve is connected with a fixed piece, the lock pin is matched with a lock pin hole arranged on a moving piece, the lock pin is inserted in the lock pin outer sleeve, a spring is arranged in the lock pin outer sleeve, a flange is arranged on the lock pin along the circumferential direction, the right end of the spring props against the flange, a pull wire fixing column is arranged in the lock pin, one end of the pull wire fixing column is connected with a pull wire, and the pull wire penetrates through the spring and the lock pin.
And a copper sleeve is embedded into the lock pin outer sleeve, and the lock pin penetrates through the copper sleeve.
And a stay wire flexible rail penetrates through the lock pin cap, and an adjusting nut is arranged on the stay wire flexible rail and clings to the top end of the lock pin cap.
Compared with the prior art, the utility model beneficial effect be: the locking pin is controlled to be inserted into or pulled out of the moving part through the pull wire penetrating through the spring, so that the locking of the swing tricycle is controlled conveniently, and the locking of the swing tricycle is realized conveniently and quickly.

Fig. 1 is a schematic structural view of the present invention in a disengaged state.
Fig. 2 is a schematic structural diagram of the present invention in a locked state.
Detailed Description
The invention will be further elucidated below on the basis of a specific embodiment.
The locking mechanism shown in fig. 1-2 comprises a lock pin, a lock pin outer sleeve, a lock pin cap and a lock pin outer sleeve, wherein the lock pin cap and the lock pin outer sleeve are mutually buckled, the lock pin outer sleeve is connected with a fixed piece, the lock pin is matched with a lock pin hole arranged on a moving piece, the lock pin is inserted in the lock pin outer sleeve, a spring is arranged in the lock pin outer sleeve, a flange is arranged on the lock pin along the circumferential direction, the right end of the spring props against the flange, a pull wire fixing column is arranged in the lock pin, one end of the pull wire fixing column is connected with a pull wire. A copper sleeve is embedded in the lock pin outer sleeve, and the lock pin penetrates through the copper sleeve. The lock pin cap is internally provided with a stay wire soft rail in a penetrating way, and the top end of the stay wire soft rail close to the lock pin cap is provided with an adjusting nut. The locking control mechanism is a locking wrench in this embodiment.
The locking mechanism works as follows: the pull wire is pulled out through buckling the locking spanner, so that when the locking mechanism is in a state shown in figure 1, the pull wire fixing column drives the lock pin to move leftwards, the lock pin is separated from a lock pin hole in the moving part, meanwhile, the lock pin compresses the spring leftwards, the lock pin cap and the lock pin extrude the spring from the left side and the right side, the adjusting nut is screwed, and the locking mechanism is kept in a separated state. The locking control mechanism is loosened by loosening the locking wrench and the like, the spring pushes the lock pin to move rightwards to the state shown in figure 2 under the reset action of the spring, the lock pin is inserted into a lock pin hole in the moving part, the adjusting nut is screwed down, and the locking mechanism is in a locking state.
In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; the specific meaning of the above terms in the present invention can be understood in specific cases for those skilled in the art.
The above description is only the preferred embodiment of the present invention, but the present invention is not limited to the above-mentioned specific embodiments, and for those skilled in the art, a plurality of modifications and improvements can be made without departing from the inventive concept of the present invention, and these modifications and improvements all belong to the protection scope of the present invention.
