The specific embodiment
As shown in Figure 2, hard open top container 30 comprises base plate 31, is separately fixed at four side plates 32 on base plate four limits and is used for removable top cover 33.On at least one side plate 32 of hard open top container 30, can be provided with one or more according to latching device 40 of the present utility model.For example, can on each of two relative side plates, be respectively equipped with two latching devices 40.
Shown in Fig. 3 A～3C and Fig. 4 A～4C, latching device 40 comprises: the outside locking bar 41 that is arranged on side plate 32; Be fixed to the pressure head 42 on the top of this locking bar 41; Be fixed to first guide 43 on this locking bar 41; And be fixed to second guide 44 on the side plate 33.Wherein, first guide 43 is provided with first helical surface 431; And second guide 44 is provided with second helical surface 441 that matches with this first helical surface 431.Here, first guide 43 is positioned at the below of second guide 44.Second guide 44 preferably is configured to hollow structure, makes locking bar 41 to pass from its hollow inside.By cooperating of first helical surface 431 and second helical surface 441, first guide 43 can carry out screw motion with respect to second guide 44, thereby it is make locking bar 41 when moving up and down, rotate, thereby movable between an open position and a locked position with respect to side plate 32.According to an embodiment, at least one (being preferably a plurality of) guide frame 49 can be set on sidewall 32, be used for action radius with locking bar 41 and be defined as and move up and down and around the rotation of self axis.Usually, side plate 32 tops of hard open top container are provided with top beam of laterally 321, are used to improve the structural strength of hard open top container 30.Locking bar 41 can pass from this top beam of laterally 321, shown in Fig. 3 B, 4B.
Also comprise in the latching device 40 and be used for first guide 43 is setovered so that the biasing element that first helical surface 431 and second helical surface 441 fit tightly to second guide 44.Biasing element can be arranged on compression spring 45 or other structures of the bottom of locking bar 41.Preferably, on side plate 32, be fixed with the spring perch 46 that is used to hold spring 45.Spring perch 46 comprises the bottom 461 that is used for support spring 45 and substantially perpendicular to the sidewall 462 of this bottom 461.Spring 45 is limited in the bottom 461 of spring perch and the space that sidewall 462 is limited, is used for supporting and the locking bar 41 of upwards setovering, thereby win helical surface 431 and second helical surface 441 are fitted tightly.
Preferably, also be provided with the handle 47 that is used to operate the activity between open position and locked position of this locking bar on the locking bar 41.When locking bar 41 was in locked position, handle 47 was positioned at the position of side plate 32, shown in Fig. 4 A.When locking bar 41 was shown in an open position, shown in Fig. 3 C, handle 47 was predetermined angular with side plate 32.Preferably, also be provided with the handle fixed mount 48 that is used for when locking bar 41 is in locked position, keeping this handle on the side plate 32.Shown in Fig. 5 A～5C, fixed mount 48 comprises bottom plate 481 and is arranged on last attachment strap 482 on this bottom plate rotationally.Bottom plate 481 is fixed on the side plate 32, and has the breach that is used to hold handle 47.Preferably, handle 47 can rotate with respect to locking bar 41, shown in Fig. 5 A, so that handle enters the breach on the bottom plate.
Shown in Fig. 5 A, when locking bar 41 was in locked position, attachment strap 482 made breach expose in the rotation.At this moment, turning handle 47 makes it enter into breach, shown in Fig. 5 B.Afterwards, attachment strap 482 makes handle 47 be limited in this breach, shown in Fig. 5 C the breach sealing in the contrarotation.Like this, locking bar 41 promptly has been maintained at locked position by handle 47 and cooperating of fixed mount 48.At this moment, envelope can also be closed in customs is arranged on the fixed mount 48.Otherwise, handle locking bar 41 thereby can make handle 47 leave fixed mount 48.
Specify the operating process of latching device 40 below.
Fig. 3 A～3C shows latching device and is in situation under the open mode.At this moment, locking bar 41 is shown in an open position; Pressure head 42 separates predetermined altitude H with the top cover 33 of hard open top container, makes top cover 33 to be removed.Preferably, pressure head 42 is configured to microscler shape, makes that the projection of pressure head 42 on plane, top cover 33 place at this moment is positioned at the next door of top cover 33 and the preset distance D of being separated by, shown in Fig. 3 C.This makes after latching device is opened, and top cover 33 can be by the safety handling, and can not interfere with latching device 40.
When needs locking top cover 33, can utilize handle 47 to handle locking bar 41 and rotate.For example, along the anticlockwise motion shown in arrow among Fig. 3 C.Here, intermeshing first helical surface 431 and second helical surface 441 are left-handed helical surface, thereby along with locking bar 41 also moves down when rotating counterclockwise.The pressure head 42 that is arranged on locking bar 41 tops is pressed on the top cover 33 up to pressure head 42 also along with locking bar 41 rotates counterclockwise and moves down, and top cover 33 is fixing with respect to side plate 32, shown in Fig. 4 A～4C.At this moment, locking bar 41 arrives locked positions, pressure head 42 with respect to the rotated position shown in Fig. 3 C about 90 degree.
When needs were opened top cover 33, counter-rotation locking bar 41 moved on making when locking bar 41 clockwise rotates by being engaged in of first helical surface 431 and second helical surface 441, thereby realized separating of pressure head 42 and top cover 33.
Should be understood that first helical surface 431 and second helical surface 441 of latching device also can be set to the right hand helix face, for example are positioned at the latching device on right side among Fig. 2.At this moment, rotate counterclockwise locking bar and can make the locking bar rising reach open position, can make locking bar move down the arrival locked position and clockwise rotate locking bar.Thereby the handle of latching device has been set at the left side of locking bar.All the other structures of latching device with right hand helix face are with foregoing identical.
Though should be pointed out that by above-mentioned embodiment the utility model is described, yet the utility model also can have other numerous embodiments.Under the prerequisite that does not break away from the utility model spirit and scope; those of ordinary skill in the art obviously can make various corresponding changes and distortion to the utility model, but these changes and distortion all should belong in the scope that the utility model claims and equivalent thereof protect.
