At present, hard-open-top containers are playing an increasingly important role in transportation. They have openings on the top to facilitate loading. They are also convenient for unloading when matched with flip racks or forklifts. They are now mostly used for loading copper concentrates, coal and other cargoes. . In the prior art, lock hooks are usually installed on the edge of the top cover, and the box body and the hook lock are connected and fixed to each other from the side of the box body. When opening the lid, the pressure block provided on the top lid hanger usually presses the tail of the top lid lock hook so that the lock hook rotates and disengages from the box body. When the lock hook is opened, the tail of the top cover lock hook can be buckled by the lock buckle provided on the top cover, so that the top cover lock hook is kept in a normally open state, which is convenient to operate and move the top cover.

However, since the lock hook only maintains the lock hook in the normally closed state by the lock hook's own weight or the torsion spring provided on the lock hook, the normally closed state of the lock hook can be destroyed only by overcoming the lock hook's own weight and the torsion force of the torsion spring. During transportation, the container jolts and shakes on vehicles, ships and other carriers, which easily makes the lock hook on the top cover thrown off, causing the top cover and the box to not be completely sealed, so that the cargo may leak.

Therefore, the top cover lock 20 of the container 100 in the present invention also has a locking device 40. When the rod 4 of the locking device 40 is in the first position, the rod 4 and the matching portion 33 on the lock hook 3 are matched and fixed. , The lock hook 3 is restricted, and the hook 32 on the lock hook 3 is clamped under the top side beam 112, so that the lock hook 3 locks the cover 12 to the box 11 to prevent the container 100 from causing damage during transportation. The shackle 3 is thrown off, and the cargo leaks. Moreover, in the second position, the rod-shaped member 4 is disengaged from the mating portion 33, so that the lock hook 3 can pivot on the fixing seat 2 under the action of an external force to be disengaged from the top side beam 112. Carry out lid opening, loading and unloading operations.

Figures 1 to 13 show the first embodiment. Specifically, as shown in FIGS. 2 and 4, the rod-shaped member 4 includes a lock rod 41, a connecting rod 42, and a sliding rod 43 that are connected in sequence, and the locking device 40 also includes a sliding rod seat fixed on the side plate 111. 5. The sliding rod 43 is sleeved in the sliding rod seat 5 and can move in a vertical direction; in the first position, the lock rod 41 is clamped and fixed with the mating portion 33.

The lock rod 41, the connecting rod 42 and the sliding rod 43 can be fixedly connected or movably connected, which can be designed according to different movement relationships, which will be described in detail below. In addition, the sliding rod 43 moves in the vertical direction in the sliding rod seat 5, so that the corresponding movable lock rod 41 also moves in a certain direction, and can move to the first position and the second position during the movement. The sliding rod seat 5 may be of an integral design, or may be of a separate design as shown in FIG. 8, as long as it can achieve the purpose of the present invention, and will not be repeated here.

Specifically, in the first specific embodiment of the present invention, as shown in FIGS. 2 to 11, the locking device 40 includes a locking plate 6 extending outward from the hook 32, and the locking plate 6 The mating part 33 is formed on the upper part, and the lock rod 41, the connecting rod 42, and the sliding rod 43 are fixedly connected; in the first position, the lock rod 41 is horizontally located at the mating part 33 away from the side plate On one side of 111, in the second position, the lock rod 41 moves to be offset from the mating portion 33 and the lock plate 6 in the vertical direction.

The sliding rod 43 moves in the vertical direction. Due to the fixed connection between the lock rod 41, the connecting rod 42, and the sliding rod 43, the lock rod 41 also moves in the vertical direction. And when the lock rod 41 moves to the first position, the lock rod 41 is located on the side of the mating portion 33 away from the side plate 111 in the horizontal direction, so that the lock rod 41 can restrict the mating portion 33 and the lock plate 6, The movement of the hook 32 prevents the lock rod 41 from rotating to the side away from the side plate 111, and prevents the lock hook 3 from being separated from the top side beam 112 of the container 100. When the sliding rod 43 moves downward and drives the lock rod 41 to move to the second position, the lock rod 41 moves to a vertical displacement with the mating portion 33 on the lock plate 6. Specifically, The lock lever 41 moves down to below the mating portion 33, so that it will not interfere with the mating portion 33, and will not affect the rotation of the lock hook 3, which facilitates operations such as lid opening, loading, and unloading.

Specifically, as shown in FIGS. 4 and 7a, the lock plate 6 penetrates in the vertical direction to form a first limiting channel 61, and the matching portion 33 is formed inside the first limiting channel 61 and close to the side. One side of the board 111.

In this specific embodiment, the first limiting channel 61 is formed through in the vertical direction, so the lock rod 41 also extends in the vertical direction. As shown in FIGS. 2 and 4, the rod-shaped member 4 The whole is U-shaped. Further, the mating portion 33 is located in the first limiting channel 61 and close to the side plate 111, so when the lock rod 41 moves to the first position, the mating portion 33 and its hook 32 can be restricted from further Move outward. Of course, if the lock plate 6 forms other structures, such as the hook-shaped limiting structure and the baffle-shaped limiting structure shown in FIG. 7b, as long as the matching portion 33 corresponding to the lock lever 41 can be provided, it can be achieved The purpose of the present invention. In this specific embodiment, the first limiting channel 61 is formed through the mating portion 33, so that the lock rod 41 can be better limited in the first position.

In addition, in this specific embodiment, the rod-shaped member 4 is U-shaped. Of course, if the rod-shaped member 4 has other shapes, that is, the lock rod 41 extends in other directions, the object of the present invention can also be achieved, as long as it can correspond to the mating portion 33 at the first position and restrict the lock hook 3 Just move outward. For example, the lock rod 41 can also extend in the horizontal direction. In the first position, the lock rod 41 can still restrict the lock hook 3 from moving outward, while in the second position, the lock rod 41 is sliding. Driven by the rod 43, the entire body moves downward, and the lock rod 41 is separated from the mating portion 33 and the lock hook 3 in the vertical direction.

In addition, one or two lock plates 6 may be provided on the lock hook 3, and the lock rod 41 is provided corresponding to the lock plate 6. That is, the lock hook 3 extends horizontally outward from one side of the lock hook 3 to form a lock plate 6, then the lock rod 41 may be provided with one and be opposite to the first limiting channel 61 on the lock plate 6. Cooperate. Of course, as shown in Figure 6, the lock hook 3 can also extend horizontally outward from the opposite sides of the lock hook 3 to form two lock plates 6, so the lock rod 41 can be provided with two The first limit channels 61 on the lock plates 6 are matched and fixed one by one.

As shown in Figures 12 and 13, in the second specific embodiment of the present invention, the hook 32 is formed with the mating portion 33 along the horizontal direction, the lock rod 41, the connecting rod 42, and the sliding rod 43 can be movably connected; in the first position, the lock rod 41 is located on the side of the mating portion 33 away from the side plate 111, in the second position, the lock rod 41 moves to the mating portion 33 The phase is misaligned in the horizontal direction.

In this specific embodiment, the mating portion 33 is formed on the hook 32. When the lock rod 41 is in the first position, the lock rod 41 corresponds to the mating portion 33, and in the second position, the The lock rod 41 moves to a horizontal position offset from the mating portion 33, indicating that the lock rod 41 moves in the horizontal direction. When the sliding rod 43 does not move downwards, the lock rod 41 is located on the side of the mating portion 33 away from the side plate 111, so that it can restrict the mating portion 33 and the lock hook 3 from moving outward; the sliding rod 43 When moving downwards, since the lock rod 41, the connecting rod 42, and the sliding rod 43 can be movably connected, the sliding rod 43 moves downward, which drives the lock rod 41 to move horizontally and gradually separates from the mating portion 33, thereby facilitating the lock The hook 3 rotates outward to open.

Specifically, as shown in FIG. 13, the hook 32 penetrates in a horizontal direction to form a second limiting channel 321, and the matching portion 33 is formed inside the second limiting channel 321 and close to a side plate 111. side.

In this embodiment, the second limiting channel 321 is formed through the horizontal direction, and the matching portion 33 is formed in the second limiting channel 321. In addition, the sliding rod 43, the connecting rod 42 and the lock rod 41 in the rod-shaped member 4 are movably connected. Therefore, when the sliding rod 43 moves downward, the lock rod 41 can be driven to move horizontally in the direction of the sliding rod 43, thereby locking The rod 41 can be separated from the second limiting channel 321.

Therefore, in the above two specific embodiments, when the forklift or the flip frame opens the lid 12 of the container 100, it first needs to extend the driving rod 9 downward to push the sliding rod 43 downward, so that the lock rod 41 is then When it is driven to move to the second position, the locking device 40 will no longer limit the lock hook 3.

In addition, as described above, in the first specific embodiment and the second specific embodiment of the present invention, both the lock rod 41 and the slide rod 43 move in a certain direction. Therefore, the lock device 40 It also includes a support 71 fixed on the side plate 111. A through hole 711 is formed through the inside of the support 71. In the first position, the lock rod 41 and/or the sliding rod 43 are both inserted through the through hole 711. . Specifically, as shown in FIGS. 2 and 4, in the first specific embodiment, the support 71 is disposed on the movement path of the lock rod 41, so as to restrict the movement of the lock rod 41 to prevent the lock rod 41 from moving. 41 forms a better guiding effect, so that it can pass through the first limiting passage 61. Or, as shown in FIG. 13, in the second specific embodiment, the lock rod 41 moves in a horizontal direction, and the support 71 can also support the lock rod 41 to ensure the movement direction of the lock rod 41 and Location. Of course, the support 71 is not limited to the structure in which the through hole 711 is formed through the inside, and may also have other structures. As long as it can achieve the function of restricting the lock rod 41, the objective of the present invention can be achieved. Go into details again.

In addition, as shown in FIGS. 4 and 13, the locking device 40 may further include a baffle 72 fixed on the side plate 111. The baffle 72 is recessed or penetrated to form a receiving space 721. In the first position, The free end of the lock rod 41 is received in the receiving space 721. The receiving space 721 in the baffle 72 also further restricts the lock rod 41 to prevent the lock rod 41 from skewing during transportation.

In addition, the sliding rod seat 5 is fixed outside the top side beam 112 or arranged inside the top side beam 112. As shown in Fig. 9a, the slide bar base 5 can be fixed to the outside of the top side beam 112; or, as shown in Fig. 9b, the slide bar base 5 can be fixed inside the top side beam 112 and is not arranged close to the edge of the top side beam 112; or As shown in FIG. 9c, the sliding rod seat 5 can be fixed inside the top side beam 112 and set against the edge of the top side beam 112. The sliding rod seat 5 and the sliding rod 43 are arranged close to the top side beam 112, which can facilitate the movement of the driving rod 9 on the forklift or the overturning frame.

Of course, after the sliding rod 43 moves downward, it needs to return to the original position after no external force is applied, and the lock rod 41 also needs to return to the first position to lock the lock hook 3. Therefore, the locking device 40 further includes a reset structure, the reset structure includes a reset spring 81, a first connection portion 82 and a second connection portion 83 connected to both ends of the return spring 81, the first connection portion 82 and the box body 11 is relatively fixed, and the second connecting portion 83 is fixed on the rod 4. Therefore, when the rod-shaped member 4 is no longer stressed, the return spring 81 will pull the second connecting portion 83 and the rod-shaped member 4 to return to their original positions.

Specifically, the return spring 81 may adopt a structure such as a tension spring, a compression spring, and an air spring.

It is known that the spring lengthens when it is pulled, and the direction of the spring itself points to the inside of the spring; the spring is compressed when it is pushed, and the direction of the spring itself points to the outside of the spring. Therefore, when the lock rod 41 is moved to the first position, the return spring 81 is in a state of being unstressed, and when the lock rod 41 is moved to the second position, the return spring 81 is in tension or compression, and then the return spring 81 is in tension or compression. The spring 81 itself has a pulling force or a pushing force. After the external force disappears, the lock rod 41 will automatically return to the first position. Specifically, whether the return spring 81 is stretched or compressed when receiving an external force can be determined by the position of the first connecting portion 82.

Specifically, as shown in FIGS. 10a and 10b, the sliding rod 43 moves downward, and the first connecting portion 82 is disposed below the second connecting portion 83, so when in the first position, the return spring 81 In the unstressed state, in the second position, the return spring 81 is compressed. As shown in Figures 11a and 11b, the first connecting portion 82 is located above the second connecting portion 83, so when in the first position, the return spring 81 is in an unstressed state, and in the second position , The return spring 81 is stretched.

Specifically, in a specific embodiment of the first return spring 81, the return spring 81 is sleeved on the outside of the lock rod 41 or the sliding rod 43, and the second connecting portion 83 is fixed on the lock rod 41 or the sliding rod 43 The first connecting portion 82 penetrates up and down to form a guide channel 821, and the lock rod 41 or the slide rod 43 is movably arranged in the guide channel 821. As shown in FIGS. 2 and 4, the return spring 81 is sleeved on the outside of the sliding rod 43, the first connecting portion 82 is arranged below the return spring 81, and a guide channel 821 is formed on the first connecting portion 82 for the locking rod. 41 passes through and moves; while in the first position, the second connecting portion 83 can be abutted against the sliding rod seat 5. In the second position, since the second connecting portion 83 is fixed on the sliding rod 43, it will be It drives downward movement, so that the return spring 81 is compressed. Similarly, as shown in Figures 10a to 10b, the return spring 81 is sleeved on the outside of the lock rod 41, the first connecting portion 82 is arranged below the return spring 81, and a guide channel 821 is formed on the first connecting portion 82 for supply The lock rod 41 passes through and moves; and the second connecting portion 83 can abut against the support 71 in the first position. In the second position, since the second connecting portion 83 is fixed on the lock rod 41, it will It is driven to move downward, so that the return spring 81 is compressed.

Of course, if in the specific embodiment of the first type of return spring 81, the first connecting portion 82 is arranged above the return spring 81, and the second connecting portion 83 is arranged below the return spring 81, then in the second position, the The return spring 81 is in a stretched state.

Alternatively, in a specific embodiment of the second return spring 81, the second connecting portion 83 is fixed on the connecting rod 42, and the return spring 81 is compressed or stretched in a direction parallel to the sliding rod 43. Specifically, as shown in Figures 11a to 11b, the first connecting portion 82 is fixed on the top side beam 112 of the box body 11, and the second connecting portion 83 is fixed on the connecting rod 42, and then in the second position, the The return spring 81 will be deformed. Of course, since the first connecting portion 82 is located above the second connecting portion 83 as described above, when in the second position, the return spring 81 is stretched. If the first connecting portion 82 is arranged below the second connecting portion 83, the return spring 81 is compressed when in the second position.

Figures 14 to 18 show the second embodiment of the present invention. Specifically, the rod-shaped member 4 includes a sliding rod 43 connected in sequence and a movable plate 44 that moves relative to the sliding rod 43. The locking device 40 also includes a sliding rod seat 5 fixed on the side plate 111. The rod 43 is sleeved in the sliding rod seat 5 and can move in a vertical direction; in the first position, the movable plate 44 is clamped and fixed with the matching portion 33.

The difference from the first embodiment is that in the second embodiment, the rod-shaped member 4 is no longer provided with a lock rod structure, but instead is provided with a movable plate 44, which can also be arranged along The sliding rod 43 moves relatively. Therefore, when the sliding rod 43 is driven, the movable plate 44 is also driven to move between the first position and the second position. In addition, in the first position, the movable plate 44 is locked and fixed with the matching portion 33 on the lock hook 3, so as to prevent the lock hook 3 from detaching and the cover 12 from accidentally opening; in the second position, the movable plate The plate 44 moves downward to disengage from the mating part 33, so that the lever member 31 of the lock hook 3 can be further driven, so that the hook member 32 is separated from the cover body 12.

Specifically, the second implementation manner includes two specific embodiments, which are a third specific embodiment and a fourth specific embodiment respectively.

As shown in Fig. 14, it is a third specific embodiment. The rod-shaped member 4 further includes a connecting rod 42, which is formed by extending from the lower end of the sliding rod 43 in a horizontal direction, and the movable plate 44 is fixed on the connecting rod 42.

Therefore, when the sliding rod 43 is driven to move downward, the connecting rod 42 and the movable plate 44 also move downward by the same distance accordingly. Therefore, when the movable plate 44 moves to the second position, the movable plate 44 is separated from the mating portion 33.
