Compared with the prior art, the utility model discloses an useful part is: when first joint and second connect along with first carriage main part, when second carriage main part produces upper and lower or front and back relative displacement, when producing fore-and-aft direction relative displacement, owing to be provided with the regulation clearance, consequently can produce the relative displacement of left right direction between first joint and the second joint, first blotter, the contact of second blotter striking, can further reduce the impact effort to the pin pole, when producing the relative displacement of upper and lower direction, the second joint can promote the second limiting plate and float from top to bottom, consequently, the impact action to the pin pole production reduces, avoid its crooked problem of extrusion in the use, when maintaining the change to the connecting piece, easily locate the pin pole and dismantle and take out.

Description of the drawings:

the present invention will be further explained with reference to the accompanying drawings.

Fig. 1 is a schematic structural diagram of the present invention.

Fig. 2 is an enlarged schematic view of the structure at M in fig. 1.

The specific implementation mode is as follows:

the present invention will be described in detail with reference to the following embodiments:

an adjustable railway carriage connector as shown in fig. 1 and fig. 2 comprises a first carriage body 1, a second carriage body 2, a first buffer cushion 3, a second buffer cushion 4, a first joint 5, a first connecting plate 51, a second joint 6, a second connecting plate 61, a pin 7, a first limit plate 71, a spring 72 and a second limit plate 8, wherein the outer ends of the two first joints 5 are fixedly arranged on the first carriage body 1, the outer ends of the two second joints 6 are fixedly arranged on the second carriage body 2, the front end of the second joint 6 is embedded in a clamping groove at the front end of the first joint 5, the first limit plates 71 are fixedly arranged at the two ends of the pin 7, the pin 7 is slidably arranged at the front ends of the first joint 5 and the second joint 6, an adjusting gap 62 of 2cm-4cm is formed between the pin 7 and the second joint 6, the spring 72 is sleeved on the pin 7, the two ends of the spring 72 respectively act on the first joint 5 and the first limit plate 71, the two second limit plates 8 are fixedly sleeved on the pin rod 7, the width of each second limit plate 8 is larger than the diameter of the pin rod 7 penetrating through a through hole at the front end of the second joint 6 by 2cm-3cm, a sliding gap of 0.5mm-1mm is formed between the inner surface of each second limit plate 8 and the second joint 6, the first cushion 3 is fixedly arranged on the first car body 1, the second cushion 4 is fixedly arranged on the second car body 2, and a buffering gap of 1cm-2cm is formed between the first cushion 3 and the second cushion 4.

In order to enhance the structural strength of the first joint 5 and the second joint 6, the two first joints 5 are fixedly connected by the first connecting plate 51, and the two second joints 6 are fixedly connected by the first connecting plate 61.

In practical use, since the front ends of the first cushion pad 3 and the second cushion pad 4 may have a problem of bending and sagging during long-term use due to their own gravity, in order to ensure that the first cushion pad 3 and the second cushion pad 4 are always in a horizontal state, the first connecting plate 51 is fixedly provided with the first guide sleeve 52, the front end of the first cushion pad 3 slides through the first guide sleeve 52, the second connecting plate 61 is fixedly provided with the second guide sleeve 63, and the front end of the second cushion pad 4 slides through the second guide sleeve 63.

A3 cm-5cm floating gap exists between the second limiting plate 8 and the upper wall and the lower wall of the clamping groove at the front end of the first connector 5, and a certain allowance gap is formed when the second limiting plate 8 drives the pin rod 7 to move up and down.

When the first joint 5 and the second joint 6 generate up-down or front-back relative displacement along with the first car body 1 and the second car body 2, when the relative displacement in the front-back direction is generated, because the adjusting gap 62 is arranged, the relative displacement in the left-right direction can be generated between the first joint 5 and the second joint 6, meanwhile, the first cushion pad 3 and the second cushion pad 4 are in collision contact, the impact acting force on the pin rod 7 can be further reduced, when the relative displacement in the up-down direction is generated, the second joint 6 can push the second limiting plate 8 to float up and down, the impact acting force generated on the pin rod 7 is reduced, the problem that the pin rod 7 is extruded and bent in the using process is avoided, and when the connecting piece is maintained and replaced, the pin rod 7 is easy to detach and take out.

It is to be emphasized that: it is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
