It is bad, and because travel it is out of control get into an accident also more, personal safety and property to people all cause loss.Existing semi-mounted
If manually form hangs over trailer on headstock by tractor to car owner, driver needs manual locking lock pin of getting off, de-
When driving trailer, it is also desirable to which driver gets off unclamps rocking bar manually, so greatly reduces the efficiency for getting rid of extension and enhances driver's
Labor intensity, but workload is larger, and virtually add many costs.
Utility model content
The purpose of this utility model is to provide a kind of tappet rod type tractor, realizes self-return and the locking of lock pin, exempts from
Except driver get on or off the bus manual locking lock pin the drawbacks of, greatly improve the efficiency for getting rid of extension and the labor intensity for alleviating driver,
The safety coefficient of driving is added, can effectively prevent the danger of trailer self falling in driving conditions.
To achieve the above object, the utility model provides a kind of tappet rod type tractor, including base, in addition to is arranged on
The guider on the base top and the locking device for being arranged on the guider top；
The guider is internally provided with trigger, and the side of the guider is provided with the connection being connected with trailer
Axle；
The locking device includes locking case, the rocking bar being arranged in the locking case, the lock being connected with the trigger
Tight plate, the shift fork being connected with the latch, lock pin and latch segment, the latch, the shift fork, the lock pin and the lock
Tight block is arranged in the locking case, and return spring is wound with the outside of the rocking bar.
Preferably, the guider includes guide way, front tension bar and guide way return pressing plate, the guide way with it is described
Front tension bar is connected, and the front tension bar is connected with the guide way return pressing plate.
Preferably, guide pin bushing is provided between the guide way and the base, the guide pin bushing is fixed on described by pressing plate
On guide way.
Preferably, the groove for placing the latch segment is provided with the lock pin.
Preferably, the connecting shaft is connected by ring flange with the front tension bar, the ring flange and the front tension bar it
Between be provided with gear bowl.
Preferably, the guide way is sector structure.
Therefore, the utility model uses the tappet rod type tractor of said structure, realizes self-return and the locking of lock pin,
Eliminate driver get on or off the bus manual locking lock pin the drawbacks of, greatly improve get rid of extension efficiency and alleviate driver work it is strong
Degree, adds the safety coefficient of driving, can effectively prevent the danger of trailer self falling in driving conditions.
Below by drawings and examples, the technical solution of the utility model is described in further detail.
Brief description of the drawings
Fig. 1 is a kind of structural representation of tappet rod type retractor embodiment of the utility model；
Fig. 2 is a kind of side view of tappet rod type retractor embodiment of the utility model；
Fig. 3 is a kind of sectional view of tappet rod type retractor embodiment of the utility model；
Fig. 4 is a kind of profile of tappet rod type retractor embodiment of the utility model；

Embodiment
Embodiment
Fig. 1 is a kind of structural representation of tappet rod type retractor embodiment of the utility model；Fig. 2 is that the utility model is a kind of
The side view of tappet rod type retractor embodiment；Fig. 3 is a kind of sectional view of tappet rod type retractor embodiment of the utility model；Fig. 4
For a kind of profile of tappet rod type retractor embodiment of the utility model；Fig. 5 is that a kind of tappet rod type tractor of the utility model is real
Apply the overall structure diagram of example.As illustrated, the utility model provides a kind of tappet rod type tractor, including base 1, also wrap
Include the guider for being arranged on the top of base 1 and the locking device for being arranged on the guider top；In the guider
Portion is provided with trigger 2, and the side of the guider is provided with the connecting shaft 3 being connected with trailer；The locking device includes
Locking case 4, the rocking bar 5 being arranged in locking case 4, the latch 6 being connected with trigger 2, the shift fork 7 being connected with latch 6, lock
Pin 8 and latch segment 9, latch 6, shift fork 7, lock pin 8 and latch segment 9 are arranged in locking case 4, and the outside of rocking bar 5 is wound with
Return spring 10, the utility model use mechanical lever principle, realize self-return and the locking of lock pin, eliminate on driver
Get off manual locking lock pin the drawbacks of, greatly improve the efficiency for getting rid of extension and the labor intensity for alleviating driver, the tractor leads to
Mechanical lever principle and the return characteristic of return spring are crossed, it is former by lever when rear haulage bar front end impact trigger lower end
Reason, stirs latch, and drives shift fork to rotate, and shift fork front end is descending, gradually locks in rear haulage rod aperture, when rear haulage bar continues
When being forwarded to bottom, lock pin comes downwards to least significant end, now, latch segment just row enter lock pin among groove, play locking lock
The effect of pin, prevent it from up, it is desirable to make lock pin up, disengage trailer, it is necessary to pull open latch segment and clamping manually, make it not
Energy self-return, can disengage trailer, the application considerably increases the safety coefficient of driving, can effectively prevent from hanging in driving conditions
