The specific embodiment
Fig. 2 is the scheme drawing according to the hard open top container 100 of an embodiment of the utility model.As shown in Figure 2, hard open top container 100 comprises: underframe 110, be used to seal hard open top container top cover 130, be separately positioned on underframe 110 both sides two side walls 120 and be separately positioned on two headwalls 140 or a door end and a front end at the two ends of underframe 110.Wherein, at least one side wall 120, can be provided with one or more according to latching device 200 of the present utility model.
As shown in Figure 3 and Figure 4, latching device 200 comprises: the pull bar 220 in the outside that can be arranged on a side wall 120 of this hard open top container between the primary importance and the second place up or down; The rotating pressure head 210 that is connected to pull bar 220 tops.Wherein, pressure head 210 comprises and pull bar 220 bonded assembly firsts 211 and the second portion 212 that cooperates with top cover 130, and first 211 is bent into predetermined angular with respect to second portion 212.When pull bar 220 is positioned at primary importance,, the locked position that pressure head 210 is positioned at, as shown in Figure 3, this moment, the second portion 212 of pressure head was pressed on the top cover 130.Along with pull bar 220 moves up, pressure head 210 can upwards lift from top cover 130 gradually, and can rotate to the direction away from top cover 130 with respect to pull bar 220.When moving to the second place on the pull bar 220, pressure head 210 separates with top cover 130, and at this moment top cover 130 can be sling and remove.Like this, operating personal only needs control pull rod on the ground can finish locking or opening operation to top cover.
Preferably, the sleeve pipe 230 that matches with pull bar 220 can be set at side wall 120 tops.More preferably, latching device 200 also comprises the pull bar collar 240 that matches with pull bar 220, and this collar is fixed on the outside of side wall 120, and pull bar 220 passes the collar 240 movably, thereby further defines the moving direction of pull bar 220.
As shown in Figure 5, more preferably, pressure head 210 also comprises salient 213, and this salient 213 protrudes to the direction away from second portion 212 from an end that links to each other with second portion 212 of first 211.The shape and the structure of pressure head 210 suitably are set, make its center of gravity be positioned at the position of close this salient 213.Like this, pressure head 210 can automatically rotate to direction (that is, away from the direction of the top cover 130) inclination of salient 213 under the effect at gravity in the process that rises with pull bar 220, thereby avoids top cover 130 to interfere with pressure head 210 in removing process.
As shown in Figure 5, between the salient 213 of pressure head and first 211 and an end that pull bar 220 links to each other, also be formed with a recess 214.Preferably, be provided with an orienting lug 290 at the top of side wall 120, this orienting lug 290 has the spigot surface of the protrusion that the recess 214 with pressure head fits.When pull bar 220 is in primary importance, as shown in Figure 3, orienting lug 290 and the direction biasing that makes pressure head 210 quilts to top board 130 cooperating of recess 214, thus make pressure head 210 can lock this top board more firmly.When pull bar 220 moved up and down, pressure head 210 can rotate with respect to pull bar 220 along this spigot surface, thereby defined the path of motion of pressure head 210, avoided pressure head 210 and other structures of open top container to produce collision.
As shown in Figure 6, preferably, on pull bar 220, also be provided with and be used to operate the handle 250 that pull bar moves.Handle is pivotally connected on the correspondence position of side wall 120 by its first end 251, and second end 252 of handle is a free end.Handle 250 is connected by a connecting rod 270 with pull bar 220, and wherein, an end of connecting rod 270 is pivotally connected to the bottom of pull bar 220, and the other end is pivotally connected to first end of handle 250 and the position between second end.When pull bar 220 was in primary importance, handle 250 was pressed close to side wall 120.Be to connect by connecting rod between handle and the pull bar, this connection mode can make pull bar have only the up-and-down movement of vertical direction with handle motion the time, and does not swing.Like this, the required aperture of the sleeve pipe that matches with pull bar is compared less with background technology.And, because pull bar can not swung, avoided scratch side wall paint or decals.In addition, two rotating shafts on the handle 250 are arranged above and below, and the turning cylinder that is used to connect handle 250 and connecting rod 270 is than being used to be connected the side wall of handle 250 with the more close hard open top container of turning cylinder of side wall.Therefore, handle 250 can be realized self-locking when pull bar 220 is in primary importance.That is, under state shown in Figure 1, handle 250 can outwards not rotate because of the pulling force that pull bar makes progress.
When needs are opened top cover 130, as shown in Figure 7, on second end 252 of handle of raising one's hand, thereby handle 250 is moved up by connecting rod 270 pushing drawing rods 220 and pressure head 210.Along with the rising of pressure head 210, it begins along orienting lug 290 to toppling over away from the direction of top cover 130, as shown in Figure 8.Arrive the second place up to pull bar 220 risings, as shown in Figure 9.At this moment, pressure head 210 is positioned at open position, and top cover 130 can be sling and remove.At this moment, sleeve pipe 230 with make pull bar 220 can not continue to move up cooperating of pull bar return portion 223.More preferably, design head 210 has enough deadweights, so that can not fall back to primary importance automatically at the situation lower link 220 that does not apply external force, thereby makes pressure head 210 can remain on open position.Like this, in removing the process of top cover, the state of pressure head 210 is stable, has guaranteed to remove the safety of operation.
More excellent, connecting rod 270 can be selected the connecting rod of adjustable in length for use, so that pressure head 210 is pressed in the adjustable in pressure of top cover 130 when being positioned at locked position.More preferably, a fixing journal stirrup 260 that matches with second end 252 of handle 250 can be set in the corresponding position of side wall 120.At this moment, also customs's envelope or lock can be arranged on fixedly journal stirrup 260.
Certainly, the utility model also can have other various embodiments, and under the situation that does not deviate from the utility model spirit and essence thereof, those of ordinary skill in the art are when making various corresponding changes and distortion according to the utility model.For example, in other embodiment of the present utility model, the rotation that pressure head biasing center of gravity produces also can realize by torsion spring, thereby pull bar is setovered to the second place.But these corresponding changes and distortion all should belong to the protection domain of the appended claim of the utility model.
