Description
Technical Field
The utility model relates to the field of trailer matching equipment, in particular to a connecting and locking mechanism used between a spring rod and a trailer during trailer.
Background
The connecting and locking mechanism used by the existing trailer is fixed on the spring rod in a welding mode, and has the defects that the connecting and locking mechanism can only be used on one type of spring rod and cannot be detached, and the trailer is also single in pairing, so that the use is inconvenient.
Disclosure of Invention
The utility model discloses a hook plate type locking device, which aims to solve the problem that a welding type trailer spring rod connecting and locking mechanism cannot be disassembled and replaced.
The technical scheme of the utility model is that the trailer spring rod connecting and locking mechanism is characterized in that a vertical square through hole is formed in the outer end of a horizontal plane connecting seat plate, a vertical fixed hook plate is arranged in the square through hole, the upper section of the fixed hook plate is bent inwards to form a hook shape, the lower section of the fixed hook plate penetrates through the connecting seat plate, a longitudinal through hole is formed in the lower end of the fixed hook plate, and a spring clamp is arranged in the longitudinal through hole;
the inner section of the connecting seat plate is bent by ninety degrees upwards to form a vertical part, and a plurality of vertical transverse through holes are formed in the vertical part of the connecting seat plate;
the inner side of the connecting seat plate is provided with a vertical lifting plate, the lifting plate is provided with a plurality of transverse through holes which are arranged up and down, and an upper connecting bolt and a lower connecting bolt are arranged between the lifting plate and the transverse through holes of the connecting seat plate;
the inner side of the lifting plate is provided with a vertical locking plate, the lower section of the locking plate is provided with a plurality of transverse through holes which are arranged up and down, a lower bolt is arranged between the locking plate and the transverse through holes of the lifting plate, and an upper bolt is arranged between the locking plate and the upper end of the lifting plate.
When the spring clip is used, the spring clip is firstly detached from the longitudinal through hole, the fixed hook plate is pulled out from the square through hole of the connecting seat plate, the spring rod is hooked by the fixed hook plate, then the fixed hook plate penetrates through the square through hole, and the spring clip is inserted into the longitudinal through hole to be locked; the height of the lifting plate is adjusted, the lifting plate is locked with the transverse through hole in the connecting seat plate through the connecting bolt, the connecting square rod of the trailer is arranged between the lifting plate and the locking plate, and the upper bolt and the lower bolt are locked with the transverse through hole in the locking plate through the lifting plate.
The connecting device has the technical effects that by adopting the technical scheme, the connecting device of the spring rod and the trailer is convenient to disassemble and assemble and flexible to use.
