As shown in fig. 1 to 14, the present invention provides a top cover 8 for a container 900, wherein the top cover 8 comprises a cover body 81 and a locking mechanism 100 disposed on the cover body 81, and fig. 1 shows the top cover 8 of the hard open top container 900, the locking mechanism 100 is generally disposed on the edge of the top cover 8, and generally one long side is provided with two, therefore, four are provided, the top cover 8 of the present invention is the same as the existing design in the distribution of the locking mechanism 100.

In the present invention, the locking mechanism 100 includes:

a first fixing seat fixed to the cover 81;

the locking hook 10 is rotatably connected to the first fixed seat, the locking hook 10 comprises a lever member 1 and a hook member 2 which are fixedly connected with each other and arranged at an angle with each other, and the hook member 2 extends downwards along the edge of the cover 81;

a stopper 3 movably connected to the cover 81 and movable to a first position and a second position; in the first position, the stop device 3 is abutted against the lever member 1; in the second position, the locking device 3 is disengaged from the lever 1.

The hook 2 extends downward along the edge of the cover 81 and, as shown in fig. 5, has a hook shape at its rear so that the hook 2 can be moved to be caught by the side panel edge of the cabinet 9. Therefore, in the present invention, when the stopping device 3 moves to the first position, the stopping device 3 abuts against the lever member 1, and the stopping device 3 is disposed on the cover 81, so that the stopping force can be provided to the lever member 1 to limit the movement of the lever member 1; the lever member 1 and the hook member 2 are fixedly connected with each other, so that the hook member 2 can be restricted from moving; therefore, the hook 2 is prevented from being separated from the case 9. Thus, even if bumping occurs during the transportation of the container 900, the latch hook 10 is prevented from being disengaged from the container body 9 due to the abutment of the stopper 3. Of course, during the unloading process, the stopping device 3 can also be moved to the second position by external force, so that the stopping device 3 is separated from the lever member 1, and thus, the hook-shaped member 2 can also be rotated and moved to be separated from the box body 9 by other external force without being subjected to the holding force.

The latch hook 10 is rotatably connected to the first fixed seat, and obviously, the latch hook 10 can be turned over relative to the first fixed seat. In this embodiment, the lever member 1 extends substantially along the surface of the cover 81, and the angle between the lever member 1 and the hook member 2 is about 90 °, so that when the end of the lever member 1 remote from the hook member 2 moves downward, the hook member 2 moves to the side remote from the housing 9, and when the end of the lever member 1 remote from the hook member 2 moves upward, the hook member 2 moves to the side close to the housing 9. Of course, the fixing place of the locking hook 10 and the first fixing seat can be located between the lever member 1 or the hook member 2 or between the lever member 1 and the hook member 2, which can achieve the above purpose.

In the above technical solution, in the first position, the stopping device 3 abuts against the lever member 1, and the stopping device 3 may abut against the lower side of the lever member 1, or may be tightened and abut against the lever member 1 above the lever member 1. The stop means 3 may take the form of a projection, catch, magnet, screw, etc.

Further, in this embodiment, the lever member 1 is connected to a first fixing seat, and the first fixing seat is formed by protruding upward from the top cover 8. The lever member 1 includes a fixing portion 11 pivotally connected to the first fixing base, and a left rod 12 and a right rod 13 disposed on two sides of the fixing portion 11, the left rod 12 is fixedly connected to the hook member 2, the right rod 13 has a lower abutting surface 131, and in the first position, the stopper 3 is located below the right rod 13 and abuts against the lower abutting surface 131. That is, the fixing place of the latch hook 10 and the first fixing seat is located at the middle position of the lever member 1, and, in the present embodiment, as shown in fig. 6, the right rod 13 extends obliquely upward from the fixing part 11, so that a space for the stopper 3 to move or abut against can be provided.

Correspondingly, the right rod 13 further includes an upper abutting surface 132 corresponding to the lower abutting surface 131, in the first position, the right rod 13 may also be located below the stopping device 3, and the stopping device 3 abuts against the upper abutting surface 132, so as to limit the upward movement of the right rod 13. In this state, the right rod 13 can be always brought close to the surface of the cover 81, and the latch hook 10 can be always kept disengaged from the case 9.

In the present invention, the left rod 12 and the right rod 13 do not represent their specific orientations, but merely represent the relative relationship between the left rod 12, the right rod 13 and the fixing portion 11.

As mentioned above, the stopping device 3 is a protrusion extending towards the lever member 1, the braking device 3 includes an upper surface 31 and a lower surface 32, and accordingly, when the latch hook 10 is locked with the box 9, the upper surface 31 of the stopping device 3 abuts against the lower abutting surface 131 of the right rod 13 to prevent the right rod 13 from moving downwards; accordingly, when the latch hook 10 is in the disengaged state of the box 9, the upper abutting surface 132 of the right rod 13 abuts against the lower surface 32 of the stopper 3 to prevent the right rod 13 from moving upward.

Of course, the lever member 1 also needs to be driven by an external force to switch between the first position and the second position. The lever member 1 can move directly under the driving of an external force, and of course, the locking mechanism 100 can also further include a driving device 4, and the driving device 4 is fixedly connected with the stopping device 3. The driving device 4 can move under the action of external force and drives the stopping device 3 to be separated from the lever member 1. The drive means 4 may be provided integrally with the stop means 3 or separately.

The locking mechanism 100 further includes an actuating device 5, the actuating device 5 includes a second fixed seat 51 fixed to the cover 81 and a movable element 52 movably connected to the second fixed seat 51, and the movable element 52 is fixedly connected to the driving device 4 and the stopping device 3. Therefore, the driving device 4 is driven and moved by the external force, and can also drive the movable element 52 and the stopping device 3 to move. The actuating means 5 equivalently provides the manner and direction of movement of the stop means 3 to limit the movement of the stop means 3 within a suitable range.

The driving device 4, the stopping device 3 and the movable element 52 may be integrally formed, or may be separately formed.

Specifically, as shown in fig. 3 to 9, according to a first embodiment of the present invention, the movable element 52 is pivotally connected to the second fixed seat 51, the driving device 4 includes a rocker portion 41 formed by extending from the movable element 52 radially outward, and the stopping device 3 is also formed by extending from the movable element 52 radially outward. In the present embodiment, the stopping device 3 and the driving device 4 both rotate around the movable element 52, so that when the driving device 4 is driven by an external force, the stopping device 3 rotates around the movable element 52 to disengage the stopping device 3 from the lever member 1. That is, the movement of the stopper 3 in the first position and the second position is formed by rotation about the movable element 52.

Since the stopper 3 is rotatable in the present embodiment, in order to facilitate the movement, the stopper 3 is also L-shaped, and specifically, in the present embodiment, the stopper 3 extends along the radial direction of the movable element 52, and then bends toward the rotation direction to form the upper surface 31 and the lower surface 32, and is conveniently abutted against the lower abutting surface 131 and the upper abutting surface 132.

Further, as shown in fig. 4, the driving device 4 further includes a force receiving portion 42 extending from an end of the rocker portion 41, and the force receiving portion 42 extends in a direction parallel to the surface of the top cover 8. The force-receiving portion 42 and the rocker portion 41 are L-shaped and extend in the extending direction of the movable member 52, and preferably, the force-receiving portion 42 and the rocker portion 41 are perpendicular to each other. The force-bearing portion 42 is used for directly contacting with an external force to drive the movable element 52 to rotate. Normally, the external force is from the pressing device 71 of the roof lifting device 7, and the pressing device 71 presses the force-receiving portion 42 downward, so that the force-receiving portion 42 is forced and rotates around the movable element 52, and also drives the stopping device 3 to rotate, so that the stopping device 3 and the lever member 1 are disengaged. Further, downward pressure is applied to the right rod 13 of the lever member 1 to lift the hook member 2 upward, so that the cover 81 and the housing 9 are separated from each other.

Of course, as shown in fig. 4, the movable member 52 can be extended long, and the driving device 4 and the stopping device 3 can be spaced apart from each other. Alternatively, the movable element 52 may be short, and the driving device 4 and the stopping device 3 may abut against each other.

As shown in fig. 10 to 14, in a second embodiment of the present invention, the movement of the stopper 3 between the first position and the second position is not performed by rotation, but by linear movement. Specifically, the second fixed seat 51 is formed with a rail extending along the extending direction of the lever member 1, and the movable member 52 is movable along the rail. Since in the second embodiment the movable element 52 projects into the track of the second fixed seat 51, it is not convenient to show it in the figures and therefore no reference numbers are given in fig. 10 to 14.

It is clear that when the movable element 52 moves closer to the lever member 1 on the rail, the stop means 3 can be brought closer to the lever member 1 and further can be held against the lever member 1, and when the movable element 52 moves farther from the lever member 1 on the rail, the stop means 3 can also move away from the lever member 1 and thus be completely disengaged from the lever member 1.

In the present embodiment, the driving device 4, the moving element 52 and the stopping device 3 are all integrated on a panel, and, as in the first embodiment, the stopping device 3 is also a projection protruding toward the lever direction and has an upper surface 31 and a lower surface 32 to realize the abutment with the lower abutting surface 131 and the upper abutting surface 132 of the right rod 13.

Moreover, the driving device 4 is wedge-shaped and has an upper surface with an inclined slope surface, and further, the inclined slope surface extends from the end close to the lever member 1 to the end far from the lever member 1 in an inclined manner, so that the driving device 4 is driven to move to the side far from the lever member 1 in the process of pressing the pressing device 71 of the top cover lifting appliance 7 downwards.

In addition, as described above, the stopper 3 is moved to the second position and disengaged from the lever member 1, and therefore, in order to restore the stopper 3 to the first position again, the lock mechanism 100 further includes the reset device 6. The resetting device 6 comprises a third fixing seat 61 fixed on the cover 81, a maintaining member 62 fixedly connected with the stopping device 3, and an elastic member 63 connected between the third fixing seat 61 and the maintaining member 62, wherein the elastic member 63 is used for providing a force to the maintaining member 62 in a direction towards the lever member 1. The third fixing seat 61 is fixed to the cover 81 so as to be immovable relative to the cover 81, and therefore the elastic member 63 always pulls or pushes the maintaining member 62 toward the lever member 1. Therefore, when no other external force is applied, the maintaining member 62 drives the stopping device 3 to push or pull towards the lever member 1 all the time, and therefore, the stopping device 3 can be located at the first position all the time. When the driving device 4 receives an external force, the stopping device 3 is driven to move to the second position in the direction away from the lever member 1 by overcoming the force of the elastic member 63, and after the external force is cancelled, the stopping device is quickly restored to the first position by the acting force of the elastic member 63.

Specifically, the position of the third fixing seat 61 can be selected by matching with the elastic member 63. For example, the third fixing seat 61 is fixed on the side of the maintaining member 62 facing the lever member 1, the stopping device 3 is located at the second position, and the elastic member 63 is in a stretched state, so that the elastic member 63 can form a pulling force on the stopping device 3 to reset the stopping device 3; conversely, the third fixing seat 61 is fixed on the side of the maintaining member 62 away from the lever member 1, and when the stopping device 3 is located at the second position, the elastic member 63 is in a compressed state, so that the elastic member 63 can push the stopping device 3 to reset the stopping device 3. The elastic member 63 may have a structure of a pressure spring, a tension spring, a torsion spring, a gas spring, or the like according to a specific situation.

In the first embodiment, as shown in fig. 7, the third fixing seat 61 is fixed on the side of the maintaining member 62 facing the lever member 1, and the elastic member 63 is used for providing a pulling force to the maintaining member 62 in the direction facing the lever member 1; in this embodiment, the retaining member 62 is also L-shaped to facilitate flipping in cooperation with the movable member 52. In a second embodiment, as shown in fig. 12, the third fixing seat 61 is fixed on a side of the maintaining member 62 away from the lever member 1, the elastic member 63 is used for providing a pushing force to the maintaining member 62 in a direction toward the lever member 1, and in this embodiment, the maintaining member 62 is also integrally formed on the same panel with the stopper 3, the driving device 4, and the like. Certainly, 5 in the utility model are not limited to above embodiment, if there are other modes still can reach the effect of the utility model, should work as and also cover within the scope of the utility model.

Specifically, in the first embodiment, as shown in fig. 5 to 9, the operation mode of the lock mechanism 100 is described.

Next, as shown in fig. 7, the stopping device 3 is moved to the second position, the driving device 4 is turned downward by the external force, the stopping device 3 is correspondingly disengaged from the lever member 1, and the elastic member 63 is further stretched.

Finally, as shown in fig. 8 and 9, the right rod 13 of the locking hook 10 is moved downwards by the external force, so that the hook 2 is turned upwards and disengaged from the edge of the box 9; further, when the external force applied to the driving device 4 is removed, the elastic member 63 pulls the maintaining member 62 toward the lever member 1, and drives the stopping device 3 to return to the first position. In this state, the lower surface 32 of the stopper 3 can abut against the upper abutting surface 132 of the right rod 13, so that the stopper 3 can press the right rod 13 downward by the tensile force of the elastic member 63 to prevent the hook 2 from moving toward the box 9.

Accordingly, in a second embodiment, as shown in fig. 10-14, the locking mechanism 100 operates.

First, as shown in fig. 10 and 12, when the stopper 3 is located at the first position, the upper side surface 31 of the stopper 3 abuts against the lower abutting surface 131 of the right bar 13 of the hook 10, so that the right bar 13 is prevented from moving downward during transportation.

Next, as shown in fig. 13, when the stopper 3 moves to the second position, the driving device 4 moves linearly in a direction away from the lever member 1 by an external force, the stopper 3 is also disengaged from the lever member 1, and the elastic member 63 is further compressed.

Finally, as shown in fig. 14, the right rod 13 of the locking hook 10 is moved downwards by the external force, so that the hook 2 is turned upwards and disengaged from the edge of the box 9; further, when the external force applied to the driving device 4 is removed, the elastic member 63 pushes the maintaining member 62 toward the lever member 1, and drives the stopping device 3 to return to the first position, and in this state, the lower surface 32 of the stopping device 3 can abut against the upper abutting surface 132 of the right rod 13, so that the stopping device 3 can press the right rod 13 downward by the pushing force of the elastic member 63 to prevent the hook-shaped member 2 from moving toward the box body 9.
