[0007] A limiting pin is inserted into the limiting holes one and the limiting holes two, and the bottom of the T-shaped groove is provided with the limiting assembly for supporting the T-shaped plug.

[0008] Preferably, the limiting assembly comprises a fixed block, the fixed block is fixedly arranged in the bottom of the T-shaped groove, two threaded holes are vertically and symmetrically formed in the top end of the fixed block, an adjusting bolt is screwed into each threaded hole from bottom to top, and one end of the adjusting bolt above the fixed block is rotatably provided with a positioning block.

[0009] Preferably, a scale line is arranged on the side of the bottom of the T-shaped groove beside the fixed block.

[0010] Preferably, the socket connecting plate is provided with a weight-reducing hole in the middle.

[0011] Preferably, the top end of the T-shaped groove and the bottom end of the T-shaped plug are provided with guiding structures.

[0012] Compared with the prior art, the utility model provides a double close contact type transition car hook for passenger car vehicle has the following beneficial effects:

[0013] 1. By setting the socket connecting plate and the plug connecting plate at the hook head end of the two close contact car hooks, the transition car hook is designed as a detachable split structure, which greatly reduces the weight of the single transition car hook, improves the operability on site, and reduces the operation strength and efficiency.

[0014] 2. By setting the limiting hole one and the limiting hole two and the limiting pin, the two close contact car hooks are longitudinally limited, and the up-down misalignment jumping is prevented.

[0015] 3. And the limiting assembly is arranged at the bottom of the T-shaped groove of the socket connecting plate, the insertion depth of the T-shaped plug is adjusted, and the two close contact car hooks with hook height difference can still be quickly and stably connected.
