Detailed description of the invention
With reference to figure 1, shown in Fig. 2, for a kind of tank container handrail being easy to fold of the present invention, be applied to the framework 10 of carrying tank container, this framework 10 is provided with to two handrails 20, be oppositely arranged on framework 10 both sides respectively, this handrail 20 comprises a push rod 30, first connecting rod 40, second connecting rod 50, third connecting rod 60, double leval jib 70, first Connection Block 80, second Connection Block 90, one outer tube 100, one expansion link 110 that can move in outer tube 100, and a lockout mechanism 120, this lockout mechanism 120 for control expansion link 110 whether can in outer tube 100 fore and aft motion.
Wherein, the annexation of above-mentioned parts is, this expansion link 110 one end to extend in outer tube 100 and expansion link 110, both outer tubes 100 push rod 30 is parallel relatively, outer tube 100, expansion link 110 are corresponding in turn to away from the other end of lockout mechanism 120 and are fixedly connected with the first Connection Block 80, second Connection Block 90; The two ends of described push rod 30 respectively with the upper end thereof of described first connecting rod 40 and second connecting rod 50, the lower end of described first connecting rod 40, the upper end of third connecting rod 60 are hinged with the upper end of the first Connection Block 80, lower end respectively, the lower end of described second connecting rod 50, the upper end of double leval jib 70 are hinged with the upper end of the second Connection Block 90, lower end respectively, the lower end of described third connecting rod 60 and double leval jib 70 is all hinged with framework 10, and lower end and framework 10 articulated position of described third connecting rod 60 and double leval jib 70 are positioned at immediately below the two ends of push rod 30.
Concrete, described outer tube 100 offers the first through hole 170 near position, expansion link 110 one end; Described lockout mechanism 120 comprises a securing rod 130, this securing rod 130 one end is inserted in outer tube 100 from described first through hole 170, during locking, securing rod 130 abuts with expansion link 110 in outer tube 100, during unblock, securing rod 130 is separated with expansion link 110 in outer tube 100, shows that an independent securing rod 130 also can complete lock function.
But the present invention is further optimized to this, as shown in Figure 3, lockout mechanism 120 also comprises spring 140, inversion and is fixed on U-shaped body 150, locating dowel pin 160 on outer tube 100; Described U-shaped body 150 top offer the second through hole 180 and this second through hole 180 for the first through hole 170 of below, side opening is provided with position-limited trough 190, described locating dowel pin 160 is positioned at this position-limited trough 190 and locating dowel pin 160 one end is fixedly connected with securing rod 130, the upper end of described securing rod 130 is arranged in the second through hole 180, and described spring 140 is placed between lower surface, U-shaped body 150 top and locating dowel pin 160.
When securing rod 130 is toward pull-up, securing rod 130 has been separated unblock with expansion link 110 in outer tube 100, now downward pressure is applied to push rod 30, first connecting rod 40, second connecting rod 50, third connecting rod 60, double leval jib 70 all rotate, opposing frame 10 tilts, form jackknife action, until together with push rod 30 collapses in framework 10.Otherwise push rod 30 recovers again to pull-up handrail 20, unclamp restoring force and lockable current state that securing rod 130 relies on spring 140.
In addition, the top of securing rod 130 is connected with a handle 200 vertical with securing rod 130, is convenient to hand force.
Described first connecting rod 40 and second connecting rod 50 are provided with clevis eye 210, and clevis eye 210 may be used for hanging tool or other article; Described push rod 30 is pipe, solves materials and alleviates handrail 20 weight.
Tank container handrail 20 of the present invention is by multiple hinged connecting rod, with the outer tube 100 of scalable adjustment and expansion link 110 as supporting mechanism, lock with lockout mechanism 120 and unlock, realize that supporting mechanism folds, folding between connecting rod, thus whole handrail 20 is collapsed on framework 10, simple to operate practical.
The foregoing is only preferred embodiments of the present invention, the present invention is not limited to above-mentioned embodiment, as long as the technical scheme realizing the object of the invention with basic same approach all belongs within protection scope of the present invention.
