The specific embodiment

In order to further specify principle of the present utility model and structure, now by reference to the accompanying drawings preferred embodiment of the present utility model is elaborated.

See also Fig. 1 to Fig. 3, Fig. 1 is the cutaway view of the twist lock device of the utility model container spreader, Fig. 2 is the structural representation of the twist lock device of the utility model container spreader, and Fig. 3 is the perspective view of the twist lock device of the utility model container spreader.Twist lock device 10 of the present utility model comprises a twist lock bar 11, is arranged on the twist lock head 12 of twist lock bar 11 1 ends, a bindiny mechanism 13, the lower limit sleeve 15 that is arranged on the upper guide bush tube 14 in the bindiny mechanism 13 and is arranged in the bindiny mechanism 13 and is oppositely arranged with upper guide bush tube 14.

Bindiny mechanism 13 comprises that one surrounds columniform sidewall 131, a upper cover plate 132 and a bottom plate 133, and this upper cover plate 132 is fixed on sidewall 131 upper ends by bolt 21, and bottom plate 133 is positioned at the lower end of sidewall 131 and is made of one piece with sidewall 131.Upper guide bush tube 14 is located at this tipping and is put in 13 and its upper end 141 is fixed on the upper cover plate 132, its lower end 142 is an opening, and the periphery of opening has a round section, evenly be provided with at interval guide groove 143 on four on this round section, last guide groove 142 comprise guiding surface 143a on one and becomes with last guiding surface 143a the angle that leads on the vertical plane 143b that leads.The lower end 152 of lower limit sleeve 15 is fixed on the bottom plate 133 of bindiny mechanism 13, its upper end 151 is an opening, and the periphery along opening has a round section, evenly be provided with at interval four lower limit grooves 153 on this round section, lower limit groove 153 comprises a lower limit inclined-plane 153a and a lower limit vertical plane 153b who becomes spacing angle with lower limit inclined-plane 153a.Wherein, the setting of staggering of last guide groove 143 and lower limit groove 153 is so that lever described later 17 rotates under the effect of last guide groove 143.

Twist lock bar 11 passes the upper cover plate 132 that runs through bindiny mechanism 13 successively, upper guide bush tube 14, the bottom plate 133 of lower limit sleeve 15 and bindiny mechanism 13, the medium position of twist lock bar 11 is provided with four levers 17 that match with last guide groove 143 and lower limit groove 153, these four levers 17 are even around twist lock bar 11 at same horizontal surface, spaced apart, twist lock bar 11 between the upper cover plate 132 of lever 17 and bindiny mechanism 13 is wound with a spring 16, the upper end butt upper cover plate 132 of spring 16, lower end butt lever 17 is limited in the lower limit groove 153 lever 17 under the effect of spring 16.

Below just working process and the principle of twist lock device of the present utility model is elaborated:

As described in Figure 2, under state of nature, lever 17 is limited under the effect of contained spring 16 in the lower limit groove 153 of lower limit sleeve 15, when twist lock device 10 is applied in downward pressure, twist lock device 10 integral body move down, when twist lock head 12 touches the inner chamber lower surface of container angle 20, twist lock bar 11 and twist lock head 12 are forced to stop to move down, upper guide bush tube 14 overcomes spring 16 under the effect of external force elastic force continues to move downward, along with moving downward of upper guide bush tube 14, lever 17 breaks away from lower limit groove 153, enter in the guide groove 143, along with upper guide bush tube 14 continue move downward, lever 17 moves along the last guiding surface 143a of last guide groove 143, lever 17 drives twist lock bar 11 and rotates, thereby driving twist lock head 12 rotates, after twist lock head 12 turns an angle, twist lock device 10 integral body under the effect of external force moves up, and twist lock bar 11 is because the pressure of spring 16 moves downward, because twist lock bar 11 has rotated certain angle, when guide groove 143 is gone up in lever 17 disengagings on the twist lock bar 11, lever 17 can move in the next lower limit groove 153, twist lock bar 11 continues to move downward under the pressure of spring 16, lever 17 moves along the lower limit inclined-plane 153a of lower limit groove 153 simultaneously, thereby driving twist lock head 12 rotates, when twist lock head 12 breaks away from obstruction (container angle 20), twist lock head 12 has rotated certain angle, thereby twist lock head 12 is hung in the hole of corner fittings 20, realizes corner fittings 20 is sling.

When freight container was finished the lifting operation, suspender needed to extract from corner fittings, and at this moment, twist lock need turn over certain angle and could extract from corner fittings, and the principle that twist lock is extracted is identical with the principle that above-mentioned twist lock puts in the corner fittings hole, gives unnecessary details no longer one by one at this.

The last guide groove of twist lock device of the present utility model by spring, upper guide bush tube and the automatic rotation of the lower limit groove realization twist lock head of lower limit sleeve need not manual operation, and have simplified hanger structure, have saved energy consumption.

The above only is preferable possible embodiments of the present utility model, and unrestricted protection domain of the present utility model.Every equivalent structure or equivalent flow process conversion that utilizes the utility model specification sheets and accompanying drawing content to do, or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
