[0049] This application provides a locking device for a container and a container including the locking device.

[0050] like Figures 1 to 4 As shown, in a specific embodiment, the container 200 includes a container body 203. The container body 203 is generally hexahedral in shape. The rear end wall of the container body 203 is equipped with a door, and a door lock assembly 201 is provided at its bottom. When the containers 200 are stacked in the container seat 300, the door of the lower container 200 is blocked by the container seat 300 and cannot be opened, while the door lock assembly 201 of the upper container 200 is exposed to the environment, allowing criminals to easily open the door and steal.

[0051] To address this issue, container 200 also includes a locking device. The locking device is used to automatically lock the door lock assembly 201 of the upper container 200 when containers 200 are stacked, preventing the container door from being opened.

[0052] like Figures 2 to 9 As shown, the locking device 100 according to the first embodiment of this application includes a housing 10, a triggering mechanism 20, a locking pin 31, and a transmission mechanism 40.

[0053] The housing 10 is used to connect to the body 203 of the container 200, for example, to the underframe of the body 203, and for example, mounted on the underside (lower surface) of the bottom plate of the underframe. The housing 10 includes a first panel 11 and a second panel 12 disposed opposite to each other along a first direction D1. The first direction D1 is, for example, the height direction of the container 200. The first panel 11 is, for example, the lower panel of the housing 10. The second panel 12 is, for example, the upper panel of the housing 10. The first direction D1 is a bidirectional direction, for example, including an upward third direction D3 and a downward fourth direction D4.

[0054] The trigger mechanism 20 passes through the first panel 11 and is at a first position relative to the first panel 11 along the first direction D1 (see...). Figure 2 ) and second position (see Figure 3 The trigger mechanism 20 is movable between the two positions. The portion of the trigger mechanism 20 located outside the housing 10 in the first position is larger than the portion of the trigger mechanism 20 located outside the housing 10 in the second position. That is, the first position is above the second position. When the trigger mechanism 20 is in the second position, it is retracted relative to the interior of the housing 10; when the trigger mechanism 20 is in the first position, it extends relative to the exterior of the housing 10.

[0055] The locking pin 31 is spaced apart from the trigger mechanism 20 along a second direction D2, wherein the second direction D2 is perpendicular to the first direction D1. The locking pin 31 is movable relative to the second panel 12 along the first direction D1. The locking pin 31 extends, for example, along the first direction D1.

[0056] A transmission mechanism 40 is disposed within the housing 10. The transmission mechanism 40 includes a first end 41 and a second end 42 disposed opposite to each other along a second direction D2. The first end 41 is rotatably connected to a trigger mechanism 20 about a first rotation axis PA1. The second end 42 is rotatably connected to a locking pin 31 about a second rotation axis PA2. The first rotation axis PA1 is, for example, parallel to the second rotation axis PA2. The first rotation axis PA1 and the second rotation axis PA2 extend, for example, along a third direction D3, which is perpendicular to the first direction D1 and the second direction D2. The second direction D2 is, for example, the front-rear direction of the container 200. The third direction D3 is, for example, the left-right direction of the container 200.

[0057] The locking device 100 is configured such that when the triggering mechanism 20 moves along the first direction D1, the rotation direction of the first end 41 of the transmission mechanism 40 relative to the triggering mechanism 20 is opposite to the rotation direction of the second end 42 of the transmission mechanism 40 relative to the locking pin 31, so that the locking pin 31 moves along the first direction D1. When the triggering mechanism 20 is in the second position, the locking pin 31 extends out of the second panel 12 along the first direction D1 to connect with the door lock assembly 201 of the container 200, making the container door unable to be opened. For example, see... Figure 4The door lock assembly 201 includes a lock hook 202, when the trigger mechanism 20 is in the second position, the lock pin 31 is inserted into the hole of the lock hook 202, locking the lock hook, so that the box door cannot be opened. The part of the lock hook 202 for connecting with the lock pin 31 is located inside the box body 203, for example, so that when the trigger mechanism 20 is in the second position, the lock pin 31 extends into the inside of the box body 203 along the first direction D1. In this way, it is more difficult to unlock the lock hook 202 from the lock pin 31.

[0058] For example, the lock pin 31 penetrates through the second panel 12. The lock pin 31 is in driving connection with the trigger mechanism 20 through the transmission mechanism 40. When the trigger mechanism 20 is in the first position, the lock pin 31 is in the third position (see Figure 2 ). When the trigger mechanism 30 is in the second position, the lock pin 31 is in the fourth position (see Figure 3 ). Wherein, the part of the lock pin 31 in the fourth position, which is located outside the shell 10, has a size larger than that of the part of the lock pin 31 in the third position, which is located outside the shell 10. That is, the fourth position is above the third position. When the lock pin 31 is in the third position, the lock pin 31 is relatively retracted towards the inside of the shell 10; when the lock pin 31 is in the fourth position, the lock pin 31 is relatively extended towards the outside of the shell 10.

[0059] Therefore, due to the reverse rotation of the two ends of the transmission mechanism 40 relative to the trigger mechanism 20 and the lock pin 31, the trigger mechanism 20 and the lock pin 31 move in the same direction along the first direction D1. When the trigger mechanism 20 moves from the first position to the second position towards the third direction D3, the lock pin 31 moves from the third position to the fourth position towards the third direction D3. When the trigger mechanism 20 moves from the second position to the first position towards the fourth direction D4, the lock pin 31 moves from the fourth position to the third position towards the fourth direction D4.

[0060] The trigger mechanism 20 in the first position protrudes beyond the outer contour of the box body 203. In this way, when the containers 200 are stacked, the trigger mechanism 20 of the locking device 100 of the upper container 200 is pushed upward by the lower container 200, causing the lock pin 31 of the locking device 100 of the upper container 200 to move upward, and the lock pin 31 enters the inside of the box body 203 of the upper container 200 to lock the door lock assembly 201, so that the box door of the upper container 200 cannot be opened.

[0061] The chassis of the container 203 has an outer bottom surface 204 and an inner bottom surface 205. The outer bottom surface 204 is the lowermost surface of the chassis. The inner bottom surface 205 is the innermost (e.g. uppermost) surface of the chassis. The trigger mechanism 20 is configured to move along the first direction D1 relative to the outer bottom surface 204 between a first position and a second position. In the first position, the trigger mechanism 20 at least partially protrudes beyond the outer bottom surface 204 to enable contact with a lower container. In the second position, the trigger mechanism 20 does not protrude beyond the outer bottom surface 204 to enable stable contact between the upper and lower containers. The locking pin 31 is configured to move along the first direction D1 relative to the inner bottom surface 205. When the trigger mechanism 20 is in the second position, the locking pin 31 protrudes beyond the inner bottom surface 205 along the first direction D1 to connect with the door lock assembly 201 of the container 200.

[0062] As shown in Figure 5 , the locking device 100 further comprises a reset member 32. The reset member 32 is arranged in the housing 10 and is configured to apply a force to the locking pin 31 to move the locking pin towards the third position, i.e. to move the trigger mechanism 20 towards the first position. When the force lifting the trigger mechanism 20 is removed, the locking pin 31 is moved back to the third position under the action of the reset member 32 to disengage from the door lock assembly 201. At the same time, the trigger mechanism 20 is moved back to the first position under the action of the reset member 32. At this time, the container door can be normally opened and closed. The reset member 32 is configured as a spring, for example.

[0063] In this application, the state of the locking device 100 in which the trigger mechanism 20 is in the second position and the locking pin 31 is in the fourth position is referred to as the triggered state. The state of the locking device 100 in which the trigger mechanism 20 is in the first position and the locking pin 31 is in the third position is referred to as the initial state.

[0064] As shown in Figures 5 to 7 , the trigger mechanism 20 comprises a striker 21 and an extension rod 22. At least part of the striker 21 is arranged in the housing 10, for example, the striker 21 is entirely arranged in the housing 10. The striker 21 is movable along the first direction D1 relative to the first panel 11. The first end 41 of the transmission mechanism 40 is rotationally connected to the striker 21 about the first rotation axis PA1. The extension rod 22 is connected to the striker 21. At least part of the extension rod 22 protrudes beyond the first panel 11. For example, the extension rod 22 is connected below the striker 21. The extension rod 22 penetrates the first panel 11.

[0065] In the first embodiment, the extension rod 22 is rotationally connected to the striker 21. For example, as shown in Figure 6 and Figure 7As shown, the triggering mechanism 20 includes a pin 25 connecting the firing pin 21 and the extension rod 22. The extension rod 22 is rotatable about the pin 25, that is, rotatable about the pin 25 relative to the firing pin 21. The first panel 11 of the housing 10 includes a receiving groove 15 for receiving the extension rod 22. The receiving groove 15 is located, for example, on the outer side of the first panel 11, recessed towards the interior of the housing 10. The pin 25 extends, for example, in a horizontal direction. When the containers 200 are stacked, the extension rod 22, for example, rotates about the pin 25 under gravity to extend along a first direction D1 (see...). Figure 6 At this angle, it moves along the first direction D1 to lock and unlock the door lock assembly 201. When it is necessary to open and close the cabinet door normally, first position the extension rod 22 in the first position, and then rotate it around the pin 25 into the receiving groove 15 (see...). Figure 7 ( ), which is stored, so that the triggering mechanism 20 cannot be triggered.

[0066] Or, such as Figure 8 As shown, the end of the extension rod 22 that connects to the firing pin 21 is constructed as a ball head. The firing pin 21 is constructed with a spherical groove to accommodate the ball head of the extension rod 22. This also allows for a rotatable connection between the extension rod 22 and the firing pin 21.

[0067] Or, such as Figure 9 As shown, the extension rod 22 is detachably connected to the striker 21, for example, by means of a threaded connection. When it is necessary to open and close the cabinet door normally, the extension rod 22 can be removed from the striker 21.

[0068] Optionally, the length of the extension rod 22 is less than or equal to 300 mm.

[0069] Optionally, such as Figures 5 to 9 As shown, the transmission mechanism 40 includes a plurality of transmission rods 50 rotatably connected sequentially from a first end 41 to a second end 42. In the initial state, the transmission rods 50 extend approximately along a second direction D2. The transmission rods 50 are constructed, for example, as levers. The actuating end of the preceding transmission rod 50 is rotatably connected to the force-receiving end of the following transmission rod 50.

[0070] For example, the transmission mechanism 40 includes two rotatably connected transmission rods 50, a first transmission rod 51 and a second transmission rod 52. The first transmission rod 51 and the second transmission rod 52 are rotatably connected by a fifth shaft 47. The force-bearing end of the first transmission rod 51 is the first end 41 of the transmission mechanism 40. The actuating end of the second transmission rod 52 is the second end 42 of the transmission mechanism 40.

[0071] Specifically, the first transmission rod 51 rotates with the third shaft 45 as a fulcrum. The position of the third shaft 45 is fixed. The first transmission rod 51 is sleeved on the third shaft 45 and can rotate around the axis of the third shaft 45 (third rotation axis PA3). The force- receiving end of the first transmission rod 51 is rotationally connected with the trigger mechanism 20 (specifically, the striker 21) through the first shaft 43. The first shaft 43, for example, penetrates the striker 21. The position of the first shaft 43 is changeable. The first shaft 43 is movable along the first direction D1 with the striker 21. The force-receiving end of the first transmission rod 51 is sleeved on the first shaft 43 and can rotate around the axis of the first shaft 43 (first rotation axis PA1). The execution end of the first transmission rod 51 is sleeved on the fifth shaft 47 and can rotate around the axis of the fifth shaft 47 (fifth rotation axis PA5). The position of the fifth shaft 47 is not fixed.

[0072] The second transmission rod 52 rotates with the fourth shaft 46 as a fulcrum. The position of the fourth shaft 46 is fixed. The second transmission rod 52 is sleeved on the fourth shaft 46 and can rotate around the axis of the fourth shaft 46 (fourth rotation axis PA4). The force-receiving end of the second transmission rod 52 is sleeved on the fifth shaft 47 and can rotate around the axis of the fifth shaft 47 (fifth rotation axis PA5). The execution end of the second transmission rod 52 is rotationally connected with the lock pin 31 through the second shaft 44. The second shaft 44, for example, penetrates the lock pin 31. The position of the second shaft 44 is changeable. The second shaft 44 is movable along the first direction D1 with the lock pin 31. The execution end of the second transmission rod 52 is sleeved on the second shaft 44 and can rotate around the axis of the second shaft 44 (second rotation axis PA2).

[0073] When the trigger mechanism 20 is triggered and moves upward toward the second position, the first shaft 43 moves upward. In turn, the force-receiving end of the first transmission rod 51 moves upward, and its execution end moves downward. Thus, the execution end of the second transmission rod 52 moves downward, and the force-receiving end of the second transmission rod 52 moves upward. In turn, the second shaft 44 moves upward, driving the lock pin 31 to move upward (see Figure 12 ). In the angle shown, when the trigger mechanism 20 moves upward toward the second position, the first end 41 of the transmission mechanism 40 (the first end of the first transmission rod 51) rotates clockwise relative to the trigger mechanism 20, and the second end 42 of the transmission mechanism 40 (the second end of the second transmission rod 52) rotates counterclockwise relative to the lock pin 31, with the two rotation directions being opposite.

[0074] When the trigger mechanism 20 moves downward toward the first position, the first shaft 43 moves downward. In turn, the force-receiving end of the first transmission rod 51 moves downward, and its execution end moves upward. Thus, the execution end of the second transmission rod 52 moves upward, and the force-receiving end of the second transmission rod 52 moves downward. In turn, the second shaft 44 moves downward, driving the lock pin 31 to move downward (see Figure 13). In the illustrated angle, when the trigger mechanism 20 moves downward towards the first position, the first end 41 of the transmission mechanism 40 rotates counterclockwise relative to the trigger mechanism 20, and the second end 42 of the transmission mechanism 40 rotates clockwise relative to the lock pin 31, the two rotation directions being opposite.

[0075] To compensate for the difference in position between the linear movement and the rotational movement, at least one of the hole for passing the first shaft 43 at the force receiving end of the first transmission rod 51 and the hole for passing the fifth shaft 47 at the execution end thereof is configured as an elongated hole. At least one of the hole for passing the fifth shaft 47 at the force receiving end of the second transmission rod 52 and the hole for passing the second shaft 44 at the execution end thereof is configured as an elongated hole. Preferably, the hole for passing the first shaft 43 at the force receiving end of the first transmission rod 51 is configured as an elongated hole, the hole for passing the second shaft 44 at the execution end of the second transmission rod 52 is configured as an elongated hole, and the hole for passing the fifth shaft 47 at the execution end of the first transmission rod 51 and the hole for passing the fifth shaft 47 at the force receiving end of the second transmission rod 52 are configured as round holes (see Figure 11 ). In this way, the transmission between the first transmission rod 51 and the second transmission rod 52 is more stable.

[0076] The first shaft 43, the third shaft 45, the fifth shaft 47, the fourth shaft 46 and the second shaft 44 are arranged in the second direction D2 in order from the first end 41 to the second end 42. The first shaft 43, the second shaft 44, the third shaft 45, the fourth shaft 46 and the fifth shaft 47 are all components of the transmission mechanism 40. The five shafts are arranged, for example, parallel to each other, which can better ensure the transmission effect. By designing the distance between the five shafts, the ratio of the movement distance of the trigger mechanism 20 and the lock pin 31 in the first direction D1 can be determined, so that the position and size of the components can be flexibly adjusted according to the specific situation.

[0077] The inner side of the first panel 11 is provided with a first support 81 for supporting the two position-invariant shafts 45 and 46. For example, the first support 81 is provided with two shaft holes, and a first bearing 48 and a second bearing 49 are respectively arranged in the two shaft holes. The first bearing 48 supports the third shaft 45. The second bearing 49 supports the fourth shaft 46. The first support 81 is fixed to the first panel 11, for example, by fasteners. The position of the fourth shaft 46 is higher than that of the third shaft 45, i.e., the fulcrum of the second transmission rod 52 is higher than that of the first transmission rod 51, which is conducive to saving the length of the lock pin 31 and raising the position of the lock pin 31.

[0078] As Figures 6 to 8As shown, the locking device 100 further comprises a connecting plate 34 and a sleeve rod 33. The sleeve rod 33 and the locking pin 31 are located on the same side of the connecting plate 34. The spring of the reset component 32 is sleeved on the outer periphery of the sleeve rod 33. The connecting plate 34 and the sleeve rod 33 move synchronously with the locking pin 31 along the first direction D1. When the locking pin 31 moves upward to the fourth position, the spring is clamped between the connecting plate 34 and the second panel 12 (see Figure 12 ), and the spring is compressed to store energy. When the trigger force acting on the trigger mechanism 20 is removed, the spring expands, causing the connecting plate 34 to move away from the second panel 12 along the first direction D1, thereby driving the locking pin 31 back to the third position (see Figure 13 ). Since the first direction D1 is the up-down direction, when the spring is activated to reset, the locking pin 31 and the trigger mechanism 20 can continue to move downward under the action of gravity.

[0079] Optionally, as shown in Figure 5 , the transmission mechanism 40 has a symmetrical structure. The trigger mechanism 20 and the locking pin 31 are generally located at the center of the locking device 100 along the third direction D3. The transmission mechanism 40 comprises two first transmission rods 51 and two second transmission rods 52. The two first transmission rods 51 are respectively located on both sides of the trigger mechanism 20 and the locking pin 31 along the third direction D3. The two second transmission rods 52 are respectively located on both sides of the trigger mechanism 20 and the locking pin 31 along the third direction D3. In this way, the transmission mechanism 40 is symmetrically arranged about the line connecting the trigger mechanism 20 (the striker 21 or the extension rod 22) and the locking pin 31, and the transmission effect of the transmission mechanism 40 is more stable. Alternatively, the trigger mechanism 20, the locking pin 31 and the transmission mechanism 40 are symmetrically arranged about the symmetry plane P, and the symmetry plane P is parallel to the second direction D2 and the first direction D1.

[0080] Optionally, the reset component 32, the connecting plate 34 and the sleeve rod 33 are also symmetrically arranged about the symmetry plane P.

[0081] Figures 6 to 9 For example, it is a sectional view along the symmetry plane P.

[0082] In Figures 10 to 13 the second embodiment, the first shaft 43 of the first end 41 of the transmission mechanism 140 of the locking device 101 is not directly connected with the striker 21, which is different from the first embodiment. In the second embodiment, the trigger mechanism 120 further comprises a connecting shaft 23 and a connecting rod 24. The first shaft 43 is connected with the connecting rod 24.

[0083] Specifically, the connecting shaft 23 extends along the third direction D3, for example. The connecting shaft 23 penetrates the striker 21. The connecting shaft 23 moves along the first direction D1 with the striker 21. The connecting rod 24 extends along the second direction D2 generally. The first end of the connecting rod 24 is connected with the connecting shaft 23, and the second end is connected with the first shaft 43. The force-affected end of the first transmission rod 51 is rotationally connected with the second end of the connecting rod 24 through the first shaft 43. When the striker 21 moves along the first direction D1, the connecting shaft 23 is driven to move along the first direction D1, and then the connecting rod 24 is driven to move along the first direction D1, and then the first shaft 43 is driven to move along the first direction D1. The transmission process from the first shaft 43 to the second shaft 44 is the same as that of the first embodiment.

[0084] Optionally, in the second embodiment, the transmission mechanism 140 further comprises a guide assembly 70. The guide assembly 70 is connected to the first shaft 43, and is used to define the moving track of the first shaft 43 as a curve. For example, the guide assembly 70 is used to define the moving track of the first shaft 43 as an arc.

[0085] For example, the guide assembly 70 comprises a guide rod 71. The first end of the guide rod 71 is rotatable relative to the housing 10 about a sixth rotation axis PA6 fixed in position, and the second end of the guide rod 71 is rotationally connected with the first shaft 43. Thus, the second end of the guide rod 71 draws a circle with the sixth rotation axis PA6 as the center, which makes the first shaft 43 move along an arc when the first shaft 43 moves along the first direction D1. Thus, the movement of the first shaft 43 is more stable, and it is less likely to appear jerky or stuck. The first shaft 43 is the starting point of the transmission mechanism 140, and the stable movement of the first shaft 43 makes the transmission of the transmission mechanism 140 more stable and the transmission precision higher.

[0086] Specifically, the inner side of the first panel 11 is provided with a second support 82. The second support 82 is fixed on the first panel 11 by fasteners, for example. The second support 82 is provided with a shaft hole. The guide assembly 70 further comprises a guide shaft 73 and a guide bearing 72. The guide bearing 72 is arranged in the shaft hole of the second support 82 and supports the guide shaft 73. The axis of the guide shaft 73 is the sixth rotation axis PA6. The first end of the guide rod 71 is sleeved on the guide shaft 73, so that the guide rod 71 can rotate about the sixth rotation axis PA6.

[0087] The guide shaft 73 and the third shaft 45 are respectively located on both sides of the first shaft 43 along the second direction D2, so that the components do not interfere with each other. The connecting shaft 23, the guide shaft 73, the first shaft 43, the third shaft 45, the fifth shaft 47, the fourth shaft 46 and the second shaft 44 are arranged in sequence along the second direction D2. The six shafts are arranged in parallel, so that the transmission is more stable.

[0088] As Figure 10 and Figure 11As shown, the shafts (the third shaft 45, the fourth shaft 46, the guide shaft 73, i.e. the shafts with fixed positions) supported by the bearings are sleeved with shaft stops 87, so that the bearings are stably positioned in the shaft holes of the supports. Thus, the rotation of these shafts is not easily interrupted or stuck, which is beneficial to the stable performance of the transmission mechanism 140.

[0089] The inner side of the first panel 11 is symmetrically provided with two second supports 82, so that the guide assembly 70 also has a symmetric structure. The trigger mechanism 120 is symmetrically provided with two connecting rods 24, so that the trigger mechanism 120 also has a symmetric structure. The trigger mechanism 120, the transmission mechanism 140 and the locking pin 31 are all symmetric about the symmetric plane P. Figure 12 and Figure 13 For example, a cross-sectional view along the symmetric plane P.

[0090] As Figure 12 and Figure 13 As shown, the housing 10 includes a first housing 17 and a second housing 18. The first housing 17 includes the first panel 11. The second housing 18 includes the second panel 12. The second housing 18 is, for example, configured in a cover style. The first housing 17 and the second housing 18 are connected by fasteners. For example, the inner side of the first panel 11 is provided with mounting posts 19, which are provided with threaded holes. Thus, the first housing 17 and the second housing 18 can be connected by bolts. This design is also applicable to the first embodiment. Alternatively, the connection (contact surface) of the first housing 17 and the second housing 18 is provided with a sealing strip 84. For example, the corresponding positions of the inner side of the first panel 11 can be provided with grooves for positioning the sealing strip 84.

[0091] The first panel 11 includes a first through hole 13 for the trigger mechanism 120 to pass through. The first through hole 13 is provided with a first sealing ring 85. For example, the inner wall of the first through hole 13 is configured with an annular stepped surface, so as to form a groove that can accommodate the first sealing ring 85. Similarly, the second panel 12 includes a second through hole 14 for the locking pin 31 to pass through. The second through hole 14 is provided with a second sealing ring 86.

[0092] The sealing strip 84, the first sealing ring 85 and the second sealing ring 86 are all designed to enhance the sealing performance of the housing 10, so as to prevent water, foreign matter, etc. from entering the inside of the housing 10. This design is also applicable to the first embodiment.

[0093] The axial direction of the first through hole 13 and the second through hole 14 is the first direction D1. The hole diameter of the first through hole 13 matches the size of the trigger mechanism 20 (for example, the outer diameter of the extension rod 22), so that the first through hole 13 simultaneously guides the movement of the trigger mechanism 20, ensuring that the trigger mechanism 20 does not skew when moving in the first direction D1. The hole diameter of the second through hole 14 matches the outer diameter of the locking pin 31, so that the second through hole 14 simultaneously guides the movement of the locking pin 31, ensuring that the locking pin 31 does not skew when moving in the first direction D1. This design is also applicable to the first embodiment.

[0094] For parts not introduced in the second embodiment, please refer to the description in the first embodiment.

[0095] Figure 14 and Figure 15 The locking device 102 according to the third embodiment of the present application is shown. The difference from the previous two embodiments is that the transmission mechanism 240 of the locking device 102 adopts a gear transmission that meshes with each other.

[0096] Specifically, the transmission mechanism 240 includes a first shaft 43, a first auxiliary transmission rod 63, a first gear shaft 65, a first gear 61, a second gear 62, a second gear shaft 66, a second auxiliary transmission rod 64, and a second shaft 44.

[0097] The first shaft 43 is arranged at the first end 41 of the transmission mechanism 240. The first shaft 43 penetrates the trigger mechanism 220, so that the first shaft 43 moves synchronously with the trigger mechanism 220 in the first direction D1. The second shaft 44 is arranged at the second end 42 of the transmission mechanism 240. The second shaft 44 penetrates the locking pin 31, so that the second shaft 44 moves synchronously with the locking pin 31 in the first direction D1.

[0098] The inner side of the first panel 11 is provided with a third bracket 83. The third bracket 83 is fixed to the first panel 11, for example, by fasteners. The third bracket 83 is provided with two shaft holes, and the first gear shaft 65 and the second gear shaft 66 are arranged in the two shaft holes respectively. The first gear 61 is connected with the first gear shaft 65 by a flat key 69, so that the two synchronously rotate around the axis (the seventh rotation axis PA7) of the first gear shaft 65. In order to make the first gear shaft 65 rotate smoothly, a third bearing 67 is arranged in the shaft hole where the first gear shaft 65 is located, and the third bearing 67 supports the first gear shaft 65. The second gear 62 is connected with the second gear shaft 66 by a flat key 69, so that the two synchronously rotate around the axis (the eighth rotation axis PA8) of the second gear shaft 66. In order to make the second gear shaft 66 rotate smoothly, a fourth bearing 68 is arranged in the shaft hole where the second gear shaft 66 is located, and the fourth bearing 68 supports the second gear shaft 66. The first gear 61 and the second gear 62 mesh with each other.

[0099] The first end of the first auxiliary transmission rod 63 is rotatably connected with the first shaft 43, for example, sleeved on the outer periphery of the first shaft 43. The second end of the first auxiliary transmission rod 63 is coaxially connected with the first gear shaft 65 and synchronously rotates, for example, sleeved on the outer periphery of the first gear shaft 65. The second end of the second auxiliary transmission rod 64 is rotatably connected with the second shaft 44, for example, sleeved on the outer periphery of the second shaft 44. The first end of the second auxiliary transmission rod 64 is coaxially connected with the second gear shaft 66 and synchronously rotates, for example, sleeved on the outer periphery of the second gear shaft 66.

[0100] In the initial state, the first auxiliary transmission rod 63 and the second auxiliary transmission rod 64 extend generally along the second direction D2. The first end of the first auxiliary transmission rod 63 is located at the first end 41 of the transmission mechanism 240. The second end of the second auxiliary transmission rod 64 is located at the second end 42 of the transmission mechanism 240.

[0101] When the trigger mechanism 220 is triggered and moves upward toward the second position, the first shaft 43 moves upward. In turn, the first end of the first auxiliary transmission rod 63 moves upward. Since the second end of the first auxiliary transmission rod 63 is limited by the third support 83 and cannot move, the first auxiliary transmission rod 63 rotates around the seventh rotation axis PA7, so that the first gear shaft 65 and the first gear 61 also rotate. In turn, the first gear 61 drives the second gear 62 to rotate, so that the second gear shaft 66 and the second auxiliary transmission rod 64 also rotate. The rotation directions of the two intermeshing gears are opposite, so that the rotation directions of the two gear shafts and the two transmission rods are also opposite. The second auxiliary transmission rod 64 rotates, causing its second end to move upward. In turn, the second shaft 44 moves upward, driving the locking pin 31 to move upward. In the angle shown, when the trigger mechanism 220 moves upward toward the second position, the first end 41 of the transmission mechanism 240 (the first end of the first auxiliary transmission rod 63) rotates clockwise relative to the trigger mechanism 220, and the second end 42 of the transmission mechanism 240 (the second end of the second auxiliary transmission rod 64) rotates counterclockwise relative to the locking pin 31, and the two rotation directions are opposite.

[0102] When the trigger mechanism 20 moves downward toward the first position, the first shaft 43 moves downward. In turn, the first end of the first auxiliary transmission rod 63 moves downward. Since the second end of the first auxiliary transmission rod 63 is limited from moving by the third support 83, the first auxiliary transmission rod 63 rotates around the seventh rotation axis PA7, causing the first gear shaft 65 and the first gear 61 to also rotate. In turn, the first gear 61 drives the second gear 62 to rotate, causing the second gear shaft 66 and the second auxiliary transmission rod 64 to also rotate. The rotation directions of the two intermeshing gears are opposite, so the rotation directions of the two gear shafts and the two transmission rods are also opposite. The rotation of the second auxiliary transmission rod 64 causes its second end to move downward. In turn, the second shaft 44 moves downward, driving the locking pin 31 to move downward. In the angle shown, when the trigger mechanism 220 moves downward toward the first position, the first end 41 of the transmission mechanism 240 (the first end of the first auxiliary transmission rod 63) rotates counterclockwise relative to the trigger mechanism 220, and the second end 42 of the transmission mechanism 240 (the second end of the second auxiliary transmission rod 64) rotates clockwise relative to the locking pin 31, with the two rotation directions being opposite.

[0103] To compensate for the difference in position between linear movement and rotational motion, the hole of the first end of the first auxiliary transmission rod 63 for the first shaft 43 to pass through is configured as a long hole, and the hole of the second end of the second auxiliary transmission rod 64 for the second shaft 44 to pass through is also configured as a long hole. The two auxiliary transmission rods are equivalent to a wrench that pries the gear shaft to rotate.

[0104] The first shaft 43, the first gear shaft 65, the second gear shaft 66, and the second shaft 44 are arranged in sequence along the second direction D2 and extend parallel to the third direction D3, so that the transmission is stable.

[0105] Optionally, the transmission mechanism 240 includes two first auxiliary transmission rods 63 and two second auxiliary transmission rods 64, the two first auxiliary transmission rods 63 are respectively located on both sides of the first gear 61 along the third direction D3, and the two second auxiliary transmission rods 64 are respectively located on both sides of the second gear 62 along the third direction D3, so that the transmission mechanism 240 is symmetrical about the symmetry plane P, and the transmission is more stable. Figure 15 For example, a cross-sectional view along the symmetry plane P By designing the transmission ratio of the two gears and the length of the two auxiliary transmission rods, the ratio of the movement distance of the trigger mechanism 220 and the locking pin 31 along the first direction D1 can be determined, so that the positions and sizes of the components can be flexibly adjusted according to specific circumstances.

[0106] As shown, the spring of the reset component 32 can be directly sleeved on the outer periphery of the locking pin 31. The locking pin 31 can be configured as a stepped shaft to limit the spring below the spring, or the second shaft 44 can also serve to limit the spring. Thus, the locking device 102 can omit the connecting plate 34 and the sleeve rod 33.

[0107] Of course, the reset member 32 can also act on the trigger mechanism or the transmission mechanism.

[0108] As shown in Figure 15 The trigger mechanism 220 is a one-piece member, i.e. the striker 21 and the extension rod 22 are formed as one piece. The trigger mechanism 220 can be integrally cast, or the striker 21 and the extension rod 22 can be bonded, welded or riveted to form one piece. In the case where the length of the trigger mechanism does not need to be reduced and the locking device can be in the initial state, the trigger mechanism can be designed as a one-piece member, simplifying the production process of the trigger mechanism.

[0109] The parts not introduced in the third embodiment can be referred to the descriptions in the first and second embodiments.

[0110] In the present application, the trigger mechanism is spaced apart from the locking pin, rather than being arranged directly below the locking pin (mainly the extension rod is not collinear with the locking pin), which can be to adapt to the structure of the container body of the container. That is, the structure of the container body does not allow the extension rod to be collinear with the locking pin. Or, it is to make the container suitable for transportation by various means of transport, i.e. the structure of the means of transport does not allow the extension rod to be collinear with the locking pin.
