Embodiment Construction
[0023] according to Figure 1~2 The specific structure of the present invention will be described in detail. The pin shaft assembly includes a pin shaft body 1 with a slot 1-2 at the end and a pin shaft cap 2 assembled at the end of the pin shaft body with an anti-loosening backstop piece 2-2. On the cylinder wall on the side of the brim 2-1 of the pin shaft cap 2, at least one fall-off prevention and backstop piece 2-2 is arranged axially. The inner hole of the pin shaft cap 2 is sleeved on the shaft end of the pin shaft body 1 periphery, and the anti-reversing sheet 2--2 of the pin shaft cap 2 is completely snapped into the draw-in groove 1-2 at the end of the pin shaft body 1 . Use the anti-off and backstop piece 2-2 to snap into the corresponding slot 1-2 at the end of the pin shaft body 1, assemble the pin shaft cap 2 at the end of the pin shaft body 1, and make the pin shaft body 1 axially limit , to prevent falling off.

The invention provides a pin shaft assembly, which effectively solves the problems of large possibility of damage and disengagement and hidden safety troubles in the prior art; the pin shaft assembly comprises a pin shaft body and a pin shaft cap, wherein a cylinder wall at one side of the brim of the pin shaft cap is axially provided with at least anti-disengagement stop sheet, and the pin shaft cap is assembled at the end part of the pin shaft body clamping the anti-disengagement stop sheet in a corresponding slot at the end part of the pin shaft body, so as to limit the pin shaft body axially. The pin shaft assembly has the characteristics of compact structure, low manufacturing cost, simple operation, convenient installation and safe and reliable use, and can not only realize anti-disengagement and adjustable detachment moment, but also achieves two functions, namely detachability and non-detachability, thus the applicable scope is widened, easy detachment in case of maintenance is realized, repeated use of the pin shaft assembly can be reached, and the purpose of enhancing operation efficiency and saving material is achieved.
Description
technical field [0001] The invention relates to a connecting piece used for connecting movable parts of mechanical equipment, in particular to a pin shaft assembly which can be disassembled quickly and prevented from falling off or being disassembled by mistake. It is suitable for various mechanical parts connected by pin shafts. Background technique [0002] As we all know, the pin connection is a common connection method for various large-scale mechanical equipment, especially large-scale transportation machinery, such as railway locomotives and other movable parts. Since the main force-bearing part of the pin shaft connection is the pin shaft body, and the main force direction of the pin shaft body is the radial shear force and the radial extrusion force on the surface, the pin shaft is generally not subject to axial force; in order to prevent the pin shaft from The shaft body moves axially, and the pin shaft body with a stopper is generally used; in order to prevent the...
