Abstract
The utility model relates to a double-layer self-locking hauling mechanism used for an internal combustion tractor. The double-layer self-locking hauling mechanism used for the internal combustion tractor comprises an operation rod, an intermediate connection rod, a rear connection rod, a hauling pin and a hauling seat. An adjusting screw rod is additionally arranged between the operation rod and the intermediate connection rod. Two ends of the adjusting screw rod are respectively a left screw thread and a right screw thread. An upper baffle plate, an intermediate baffle plate and a lower baffle plate are arranged on the hauling seat. Pin holes in the upper baffle plate, the intermediate baffle plate and the lower baffle plate are matched with the hauling pin. According to the double-layer self-locking hauling mechanism used for the internal combustion tractor, self-locking or non-self-locking is achieved due to the arrangement of the adjusting screw rod, only a driver in a cab can operate the hauling pin under the self-locking condition and the hauling pin is prevented from unhooking due to unevenness of a road and bumping or being lifted by other people, and reliability and safety are guaranteed. Due to the structural design that the pin holes in the upper baffle plate, the intermediate baffle plate and the lower baffle plate are matched with the hauling pin, the double-layer self-locking hauling mechanism used for the internal combustion tractor can be widely applied to platform trailers with trailing handles at different height.

The outer end of described lower baffle plate 11 stretches out, and is bent downwardly.
Useful technique effect of the present utility model embodies in the following areas:
1. the position that the utility model can be by changing adjusting screw(rod) is adjusted to self-locking state or self-locking state not with towing pin, during self-locking state, only chaufeur just can operate towing pin in operator's compartment, towing pin can be because of Uneven road, jolt, cause towing pin to break off relations, or mentioned by the stranger, reliability, safety improve greatly;
2. the structure design that coordinates with the pin-and-hole of overhead gage, middle baffle plate and lower baffle plate respectively of towing pin, adapt to and drag the wider of the different flat-bed trailer of handle height.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is not self-locking state figure of the utility model.
Fig. 3 is the traction seat structural scheme of mechanism.
Fig. 4 is the partial enlarged drawing of Fig. 1.
Sequence number in upper figure: joystick 1, front frame 2, adjusting screw(rod) 3, after poppet 4, middle connecting rod 5, rear linking rod 6, traction seat 7, orienting sleeve 8, overhead gage 9, middle baffle plate 10, lower baffle plate 11, towing pin 12, back balance weigh 13, left u shaped connector 14.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described by embodiment.
Embodiment:
Referring to Fig. 1, the double-deck self-locking trailer coupling that is used for gas tractor comprises joystick 1, connecting rod 5, rear linking rod 6, towing pin 12 and traction seat 7, and described middle connecting rod 5, rear linking rod 6 and towing pin 12 are rotationally connected successively.Referring to Fig. 4, the front end of joystick 1 is handle, and posterior rotation is connecting front frame 2, and the back balance that front frame 2 is arranged on tractor truck weighs on 13; The rear end of joystick 1 is connecting an end of left u shaped connector 14, and the other end of left u shaped connector 14 is welded with left nut; Middle connecting rod 5 is L shaped bar, and its bending place is being rotationally connected after poppet 4, and the back balance that after poppet 4 is arranged on tractor truck weighs on 13; One end of middle connecting rod 5 is welded with right nut; Left nut be connected nut and connecting respectively an end of adjusting screw(rod) 3, an end of adjusting screw(rod) 3 is minus thread, the other end is right-hand screw thread.Referring to Fig. 3, traction seat 7 is for uprightly tabular, and is arranged on back balance and weighs 13 rear portion; Be separately installed with the overhead gage 9 of level, the middle baffle plate 10 of level and the lower baffle plate 11 of level on traction seat 7 from top to bottom, the outer end of lower baffle plate 11 stretches out, and is bent downwardly.Overhead gage 9, middle baffle plate 10 and lower baffle plate 11 are parallel to each other, and offer respectively coaxial pin-and-hole; On the overhead gage 9 corresponding with pin-and-hole, orienting sleeve 8 is installed, the lower end of towing pin 12 is positioned at orienting sleeve 8, and towing pin 12 coordinates with the pin-and-hole of overhead gage 9, the pin-and-hole of middle baffle plate 10 and the pin-and-hole of lower baffle plate 11 respectively.
