The specific embodiment
Below, by exemplary embodiment the utility model is specifically described.Yet should be appreciated that under the situation that is not having further narration element, structure and feature among embodiment also can be attached in other embodiment valuably.
Fig. 2 shows a kind of according to hard open top container 30 of the present utility model, and it comprises: underframe 31; Be separately fixed at four walls on four limits of underframe 31, comprise two sidewalls 32 that lay respectively at the underframe both sides and two end walls 33 that lay respectively at the underframe two ends; And the top cover 34 that is used to seal this hard open top container.Wherein, the arranged outside at least one wall has at least one according to latching device of the present utility model.For example, can be at two latching devices 40 of arranged outside of or each sidewall 32.Should be appreciated that the quantity that is arranged on the latching device on each wall can be different.
Fig. 3 shows the latching device 40 according to an embodiment of the utility model, and it comprises: the locking bar 41 that is arranged on a cooresponding wall (for example sidewall 32) outside; Corresponding to the stationkeeping of locking bar 41 lock pin 42 to the top cover 34; And the pressure head 43 that is connected to the top of locking bar 41.Wherein, the through hole on the back timber 321 of corresponding sidewall is passed on the top of locking bar 41, and can move up and down between a lower primary importance (seeing Fig. 4 A) and a higher second place (seeing Fig. 4 D).Pressure head 43 can rotate between a latched position (seeing Fig. 4 A) and an open position (seeing Fig. 4 D) along with moving of locking bar 41, and wherein pivot center R is approximately perpendicular to corresponding side walls 32.With reference to figure 5, pressure head 43 comprises the first 431 that is used for linking to each other with locking bar 41, be used for the second portion 432 that cooperates with lock pin 42 and be connected third part 433 between first and second parts.Lock pin 42 stretches out from top cover 34 along the direction that is approximately perpendicular to sidewall 32, thereby can match with pressure head 43 to realize locking.
Specify the operating process of latching device 40 below with reference to Fig. 4 A-4C and index map 3 and Fig. 5.
When latching device 40 was in the lock state, shown in Fig. 4 A, locking bar 41 was in a lower primary importance, and pressure head 43 is pressed on the lock pin 42 by its first 431, thereby top cover 34 is locked onto current location.Open top cover 34 as need, can will move on the locking bar 41, be in a higher second place up to it, shown in Fig. 4 D.This moment, pressure head 43 separated with respect to locking bar 41 upsets and with lock pin 42, made top cover 34 to open.Locking bar 41 is moved down into primary importance again, can realize locking once more top cover 34.The operating personal that is arranged so that of locking bar 41 can be operated pressure head 43 on the ground, realizing the locking of top cover and to open, thus easy to operate.
It should be noted that therefore when pressure head 43 was shown in an open position, it was turned on the back timber 321 of sidewall, and can not exceed the outline scope of hard open top container 30 because pressure head 43 rotates around the pivot center R that is approximately perpendicular to sidewall 32.Like this, can avoid pressure head 43 because of collision damages on the one hand, can reduce the required space of open operation of latching device 40 on the other hand.Preferably, lock pin 42 is not more than the distance D 2 of outline of this hard open top container respective side of Edge Distance of top cover 34 with respect to top cover 34 outward extending preset distance D1, thereby can avoid lock pin 42 to damage because of collision.
Preferably, the shape of design head 43 and structure make when latching device 40 is in the lock state, and shown in Fig. 4 A, the center of gravity of pressure head 43 is positioned at a side away from lock pin 42 with respect to the perpendicular P at described pivot center R place.In Fig. 4 A, lock pin 42 is positioned at the left side of this perpendicular P, and the center of gravity of pressure head then is positioned at the right side of this plane P.Like this, when moving on the locking bar 41, pressure head 43 can be from the direction upset of trend away from lock pin 42 under the effect of gravity.
Preferably, the shape and the structure of all right design head 43, make when latching device 40 is in the lock state, at least a portion of pressure head first 431 is limited in the through hole of side plate back timber 321, thus can by pressure head first 431 with avoid pressure head 42 undesirable upsets cooperating of through hole.At this moment, when moving on the locking bar 41, pressure head 42 is at first gone up together with locking bar 41 and is moved and do not rotate, shown in Fig. 4 B.After pressure head first 431 shifted out through hole fully, pressure head 42 beginnings were overturn under the effect of gravity, shown in Fig. 4 C, open fully up to it, shown in Fig. 4 D.Pressure head first 431 with this cooperation of through hole can also avoid scratching between pressure head 43 and the lock pin 42; And if pressure head 43 directly overturns from latched position, then might scratch lock pin 42 or scratched by lock pin 42.
Preferably, pressure head 43 back to a side of lock pin 42, near the connection location of its first 431 and third part 433, also be formed with a recess 434.On cooresponding back timber 321, be provided with a lug boss 322, be used for matching with recess 434.In the process of pressure head 43 upsets, recess 434 fits with lug boss 322, pressure head 43 is led, thereby avoid pressure head 43 to strike suddenly on the back timber 321.
Get back to Fig. 3, also can comprise according to catch gear of the present utility model being used to operate the operating mechanism that locking bar 41 moves up and down.Operating mechanism comprises handle 45 and connecting rod 46.One end 45a of handle 45 is pivotally connected on the corresponding side walls 32, and other end 45b is a free end.One end 46a of connecting rod 46 is pivotally connected to the bottom of locking bar 41, and other end 46b is pivotally connected to the two ends 45a of handle 45 and the position between the 45b.Like this, upwards lift handle 45 and can realize moving on the locking bar 41, rotate handle 45 and can realize that locking bar 41 moves down, easy to operate.Preferably, the length of locking bar 41 can be regulated, thereby can regulate when latching device 40 is in the lock state the pressure between top cover and the wall.
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.
