Abstract
The utility model relates to a seat is pull to the semitrailer saddle, specifically is a set bar is pull to semitrailer saddle. Including the set bar body, the nonworking face thickness of set bar body is greater than working face thickness, is the stairstepping structure. The utility model discloses a stairstepping structural design of set bar body has improved the mechanical properties intensity and the impact resistance of set bar body, the effect having played increase of service life and practiced thrift cost of maintenance.
Description
Technical field
The utility model relates to superimposed trailer saddle-type traction base, specifically a kind of superimposed trailer saddle-type traction base locking bolt.
Background technology
As the vitals of lockable mechanism, in use, locking bolt needs to bear larger impact load, and the mechanical characteristics of locking bolt needs to improve further.
Utility model content
The utility model is intended to solve the problem, thus provides a kind of superimposed trailer saddle-type traction base locking bolt that can improve mechanical characteristics and safety in utilization, increase the service life.
The utility model solves described problem, and the technical scheme of employing is:
A kind of superimposed trailer saddle-type traction base locking bolt, comprise cylinder body, the non-working surface thickness of cylinder body is greater than driving surface thickness, in ladder-type structure.
Adopt the utility model of technique scheme, compared with prior art, its outstanding feature is:
Designed by the ladder-type structure of cylinder body, improve mechanical properties strength and the impact resistance of cylinder body, serve the effect increasing the service life and save maintenance cost.
As preferably, the utility model further technical scheme is:
The non-working surface thickness of cylinder body is greater than 25mm.
The front end of cylinder body is wedge structure, guarantees that cylinder body can slide to lock position automatically when traction seated connection is hung.
The driving surface of cylinder body is provided with counter sink, guarantees that slip plane is without additional friction.
Cylinder body is the one-shot forming structure of closed-tolerance forging, improves the mechanical properties strength of cylinder body.
Accompanying drawing explanation
Fig. 1 is the utility model example structure front view.
Fig. 2 is the structural representation during the utility model embodiment uses.
In figure: driving surface 1, counter sink 2, non-working surface 3, cylinder body 4, wedge structure 5, hand lever 6, bearing pin 7.
detailed description of the invention:
Below in conjunction with embodiment, the utility model is described in further detail, and object is only to understand the utility model content better, and therefore, the cited case does not limit protection domain of the present utility model.
See Fig. 1, Fig. 2, non-working surface 3 thickness of cylinder body 4 is greater than driving surface 1 thickness, in ladder-type structure, the thickness of driving surface 1 is determined according to Standard, thus it is constant with the relative position of traction seat housing to guarantee to pull thick stick 6, increase the thickness of non-working surface 3, non-working surface 3 thickness is greater than 25mm, improve mechanical properties strength and the impact resistance of cylinder body 4, serve the effect increasing the service life and save maintenance cost, cylinder body 4 is the one-shot forming structure of closed-tolerance forging, improve the mechanical properties strength of cylinder body 4, the driving surface 1 of cylinder body 4 is provided with counter sink 2, be connected with hand lever 6 by bearing pin 7, counter sink 2 design guarantees that the driving surface 1 of cylinder body 4 penetrates the rear slip plane of bearing pin 7 without additional friction, the front end of cylinder body 4 is wedge structure 5, guarantee that cylinder body 4 can slide to lock position automatically when traction seated connection is hung.
The foregoing is only the better feasible embodiment of the utility model, not thereby limit to interest field of the present utility model, the equivalence change that all utilization the utility model specification sheetss and accompanying drawing content thereof are done, be all contained within interest field of the present utility model.
