[0025] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the scope of protection of the present invention.

In addition, the terms "first", "second", "third" and the like are only for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0027] In the description of the present application, it should be noted that, unless otherwise specified and limited, the terms "mounting", "connection", "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0028] As shown in Figure 1 The preferred embodiment of the present application provides a locking device for a container, which comprises a latch 10 and a locking mechanism 20 connected to the latch 10. In this embodiment, the locking mechanism 20 can drive the relative movement between the latch 10 and the locking mechanism 20, so as to unlock or lock the door body 30 of the container.

[0029] Further, with reference to Figure 2 The locking mechanism 20 comprises a mounting seat 21, a driving member 23 rotatably arranged in the mounting seat 21 and drivingly connected to the latch 10, and a safety mechanism 25 arranged on the mounting seat 21 and cooperating with the driving member 23.

[0030] In this embodiment, the locking mechanism 20 drives the relative movement between the latch 10 and the mounting seat 21 by rotating the driving member 23. And the driving member 23 is locked by the safety mechanism 25, so that the latch 10 cannot be further moved after moving to a specified position. The specified position can be set according to the needs of the user, for example, when the door body 30 of the container is in the locked state or in the unlocked state.

[0031] Specifically, with reference to Figure 3As shown, the safety mechanism 25 includes a limiting pin 25a elastically arranged on the mounting base 21, the limiting pin 25a extends towards the driving member 23, the driving member 23 has a first limiting hole 23a matched with the limiting pin 25a, and when the driving member 23 rotates to drive the bolt 10 to the locked state, the limiting pin 25a extends into the first limiting hole 23a.

[0032] In this embodiment, the limiting pin 25a extends along the direction towards or away from the driving member 23, and the extending direction of the limiting pin 25a intersects with the rotating direction of the driving member 23, when the limiting pin 25a extends into the first limiting hole 23a, the driving member 23 cannot rotate.

[0033] And, since the limiting pin 25a elastically abuts in the safety mechanism 25, the limiting pin 25a is always subjected to an elastic extrusion force towards the driving member 23, when the driving member 23 rotates to drive the bolt 10 to the locked state, the limiting pin 25a coincides with the central axis of the first limiting hole 23a, at this time the elastic extrusion force provided by the safety mechanism 25 to the limiting pin 25a drives the limiting pin 25a to extend into the first limiting hole 23a, to limit the further rotation of the driving member 23, thereby limiting the relative displacement between the bolt 10 and the locking mechanism 20.

[0034] The locking device drives the bolt 10 to extend into the box by the rotation of the driving member 23, and when the bolt 10 moves to the locked state, the limiting pin 25a of the safety mechanism 25 extends into the first limiting hole 23a, thereby locking the bolt 10, ensuring the safety of the container storage and transportation.

[0035] Specifically, the mounting base 21 includes a lock bottom plate 21a rotationally matched with the driving member 23, a lock cover plate 21b connected to the lock bottom plate 21a and located on one side of the driving member 23, and the limiting pin 25a is movably arranged in the lock cover plate 21b along the rotating axis direction of the driving member 23.

[0036] In this embodiment, the driving member 23 is rotationally arranged in the lock bottom plate 21a around its rotating axis, and the driving member 23 and the lock bottom plate 21a cannot produce displacement along the rotating axis direction of the driving member 23.

[0037] Moreover, in this embodiment, the lock cover plate 21b is fixed to the lock bottom plate 21a by fasteners and is used to mount the safety mechanism 25, and the extending direction of the limiting pin 25a is parallel to the rotating axis direction of the driving member 23. Moreover, since the limiting pin 25a is movably arranged in the lock cover plate 21b, the limiting pin 25a produces displacement perpendicular to or intersects with the rotating axis direction of the driving member 23.

[0038] In some embodiments, the extension direction of the limiting pin 25a can also be perpendicular to or intersect with the rotation axis direction of the driving member 23, as long as the limiting pin 25a can extend into the first limiting hole 23a and the driving member 23 cannot rotate.

[0039] Further, the safety mechanism 25 further comprises a movable member 25b connected with the limiting pin 25a, a fixed member 25c connected with the lock cover plate 21b and matched with the movable member 25b, and an elastic member 25d arranged in the fixed member 25c and abutting against the movable member 25b. The movable member 25b is arranged on the side of the lock cover plate 21b away from the driving member 23 and movably arranged in the fixed member 25c along the rotation axis direction of the driving member 23.

[0040] In the embodiment, the limiting pin 25a is fixedly connected with the movable member 25b, so that the movable member 25b reciprocates along with the extension and retraction of the limiting pin 25a, and the movement track is parallel to the rotation axis of the driving member 23.

[0041] The movable member 25b is movably arranged in the fixed member 25c. Since the fixed member 25c is fixed to the lock cover plate 21b by fasteners, and one end of the elastic member 25d abuts against the fixed member 25c and the other end abuts against the movable member 25b, the elastic member 25d provides the movable member 25b and the limiting pin 25a with elastic extrusion force towards the driving member 23.

[0042] The elastic member 25d in the embodiment is preferably a spring, so as to save production cost. Moreover, since the movable member 25b adopts a plate structure, the contact area between the movable member 25b and the elastic member 25d is increased, so that the elastic member 25d more stably transmits the elastic extrusion force to the limiting pin 25a.

[0043] Further, the safety mechanism 25 further comprises an unlocking pin 25e connected with the movable member 25b and protruding towards the driving member 23. In the embodiment, the unlocking pin 25e is fixedly connected with the movable member 25b. When the user needs to unlock the driving member 23 to make it rotate further, the user only needs to press the unlocking pin 25e to move towards the side of the elastic member 25d. When the unlocking pin 25e presses the elastic member 25d to move towards the side of the elastic member 25d, the unlocking pin 25e drives the movable member 25b and the limiting pin 25a to move towards the side away from the driving member 23, so that the limiting pin 25a extends out of the first limiting hole 23a, and at this time the driving member 23 can rotate.

[0044] Specifically, the driving member 23 has a driving plate 23b arranged in the lock bottom plate 21a in a matched manner, and an unlocking hole 23c arranged on the driving plate 23b and matched with the unlocking pin 25e. The central axis of the unlocking pin 25e, the central axis of the unlocking hole 23c and the central axis of the driving plate 23b coincide with each other.

[0045] In the embodiment, the driving plate 23b is provided in a cylindrical plate shape, so that the central axis of the driving plate 23b coincides with the rotation axis of the driving member 23. The lock bottom plate 21a is provided with a rotation hole matched with the driving plate 23b, and one side of the driving plate 23b abuts against the lock cover plate 21b to limit the deviation of the driving plate 23b toward the side of the lock cover plate 21b.

[0046] In the embodiment, the unlocking hole 23c is provided in a polygonal cross section, for example, a square. When the user needs to unlock the driving member 23, the unlocking tool 50 is inserted into the unlocking hole 23c, and then pressed against the unlocking pin 25e. The unlocking tool 50 is provided in a polygonal cylindrical structure matched with the unlocking hole 23c, so that the driving plate 23b is rotated to drive the driving member 23 to rotate and move the bolt member 10.

[0047] Specifically, the lock cover plate 21b has a lock cover body 21b1, a first lock cover through hole 21b2 provided on the lock cover body 21b1 and matched with the limiting pin 25a, and a second lock cover through hole 21b3 provided on the lock cover body 21b1 and matched with the unlocking pin 25e. The limiting pin 25a is movably arranged in the first lock cover through hole 21b2 along the rotation axis direction of the driving member 23, and the unlocking pin 25e is movably arranged in the second lock cover through hole 21b3 along the rotation axis direction of the driving member 23.

[0048] In the embodiment, the first lock cover through hole 21b2 and the second lock cover through hole 21b3 are provided to avoid the deviation of the limiting pin 25a and the unlocking pin 25e perpendicular to or intersecting with the rotation axis direction of the driving member 23, and to ensure the stable extension and contraction of the limiting pin 25a. The thickness of the lock cover body 21b1 can be set as needed, as long as the limiting pin 25a can be completely extended into the first limiting hole 23a and the rotation of the driving member 23 is limited.

[0049] Specifically, referring to Figure 4 Specifically, referring to

[0050] In the embodiment, the sleeve 25c1 is provided in a cylindrical structure matched with the elastic member 25d, and is hollow inside to mount the elastic member 25d, so that the elastic member 25d is not easy to tilt when deformed under stress, thereby stably applying pressure to the movable member 25b.

[0051] The movable groove 25c2 extends along the rotation axis of the drive member 23, so that the movable member 25b can only reciprocate along the rotation axis of the drive member 23, and cannot rotate around the rotation axis of the drive member 23. Therefore, when the user presses the unlocking pin 25e, causing the limiting pin 25a to extend out of the first limiting hole 23a, even if the limiting pin 25a abuts against the end face of the drive plate 23b when the drive member 23 continues to rotate, the drive member 23 cannot move the limiting pin 25a.

[0052] In addition, the depth of the movable groove 25c2 along the rotation axis of the drive member 23 can be set as needed, as long as the limit pin 25a is still in the first locking cover through hole 21b2 when the movable member 25b abuts against the bottom of the groove.

[0053] Moreover, the shape of the movable groove 25c2 matches that of the movable part 25b, making it less likely for the movable part 25b to deviate when it reciprocates within the movable groove 25c2.

[0054] Furthermore, the fixing member 25c has two movable grooves 25c2 symmetrically arranged along the central axis of the sleeve 25c1 and two fixing plates 25c3 symmetrically arranged along the central axis of the sleeve 25c1. The line connecting the two movable grooves 25c2 is perpendicular to the line connecting the two fixing plates 25c3. The safety mechanism 25 includes at least two limiting pins 25a. The unlocking pin 25e is located at the symmetrical center of the movable member 25b. The at least two limiting pins 25a are symmetrically arranged with respect to the unlocking pin 25e.

[0055] In this embodiment, as Figure 4 The movable part 25b and the fixed part 25c are arranged in an "X" shape, so that when the limiting pin 25a abuts against the end face of the drive plate 23b, even if the drive part 23 continues to rotate, the fixed part 25c can stably restrict the movable part 25b in the movable groove 25c2, and the movable part 25b cannot rotate in the movable groove 25c2, thereby improving the structural strength of the safety mechanism 25.

[0056] Furthermore, since the safety mechanism 25 has two simultaneously retractable limiting pins 25a, the two limiting pins 25a are located on both sides of the rotation axis of the drive member 23, and the drive member 23 is provided with two corresponding first limiting holes 23a, when the two limiting pins 25a simultaneously extend into the corresponding two first limiting holes 23a, the drive member 23 cannot rotate further or produce rotational deviation, thereby improving the locking strength of the safety mechanism 25 on the drive member 23.

[0057] Furthermore, in conjunction with reference Figure 5As shown, the driving member 23 further has a second limiting hole 23d arranged on the driving plate 23b and matched with the limiting pin 25a, and the first limiting hole 23a is arranged on the driving plate 23b, and the distance between the first limiting hole 23a and the central axis of the driving plate 23b is equal to the distance between the second limiting hole 23d and the central axis of the driving plate 23b.

[0058] In the embodiment, when the user unlocks the driving member 23 and reversely rotates the driving member 23 to the specified position, the limiting pin 25a will extend into the second limiting hole 23d, thereby limiting the further rotation of the driving member 23. The arrangement of the second limiting hole 23d can avoid the excessive reverse rotation of the driving member 23, which may cause the interference and damage of other components in the locking mechanism 20, and can also avoid the shaking of the driving member 23 in the unlocked state, which may cause the relative displacement between the bolt member 10 and the locking mechanism 20.

[0059] Further, the number of the second limiting hole 23d can be matched and set according to the number of the limiting pin 25a. In the embodiment, two second limiting holes 23d are preferred, which are corresponding to the two first limiting holes 23a and are arranged on the same circumferential line.

[0060] Further, continuing to refer to Figure 1 As shown, the locking mechanism 20 further includes a transmission member 27 connecting the bolt member 10 and the driving member 23, one end of the transmission member 27 is hinged to the driving member 23, and the other end is hinged to the bolt member 10.

[0061] In the embodiment, one end of the transmission member 27 is hinged to the edge of the driving plate 23b. The arrangement of the transmission member 27 converts the rotary motion of the driving member 23 into the linear motion of the bolt member 10. With the rotation of the driving member 23 towards different directions, the bolt member 10 is displaced towards the direction away from the locking mechanism 20 or towards the locking mechanism 20.

[0062] Further, the locking device includes at least two bolt members 10. In the embodiment, the locking device includes two or more bolt members 10, thereby being capable of unlocking or locking the two ends of the door body 30 at the same time, reducing the manufacturing cost and saving the occupied space of the container. The two bolt members 10 are oppositely arranged at the two ends of the locking mechanism 20, and can be used to unlock or lock the upper and lower, front and rear or left and right ends of the door body 30 at the same time. When the unlocking device is used to unlock or lock the upper and lower ends of the door body 30, it is a top and bottom lock.

[0063] Further, continuing to refer to Figure 2 and Figure 4 As shown, the locking mechanism 20 includes the transmission member 27 corresponding to the aforementioned at least two bolt members 10, and the lock cover plate 21b further has two limiting openings 21b4 arranged on the lock cover body 21b1 and matched with the transmission member 27.

[0064] In the embodiment, when the locking device is provided with two plug members 10, the locking mechanism 20 is also provided with two transmission members 27, so as to simultaneously drive the two plug members 10.

[0065] The limiting opening 21b4 is arranged according to the movement track of the transmission member 27, that is, when the driving member 23 rotates to two specific positions, the limiting opening 21b4 is arranged according to the space occupied by the transmission member 27. The arrangement of the limiting opening 21b4 provides space for the movement of the transmission member 27, so as to avoid the interference between the plurality of transmission members 27 when the driving member 23 rotates excessively, and to avoid the damage of the locking mechanism 20.

[0066] Reference Figures 6 to 7 As shown in the figure, the preferred embodiment of the present application provides a container, which comprises the above-mentioned locking device, the structure of the locking device is as described above, and details are not described herein again. The locking device is installed on the door body 30 of the container. After the door body 30 is closed, the operator uses the unlocking tool 50 to lock the door body 20 on the box body. When it is needed to open the door body 20, the door body 20 can be opened only after being unlocked by the unlocking tool 50, so as to ensure the safety of the container for storing and transporting goods.

[0067] Specifically, referring to Figure 6 As shown in the figure, a container comprises a box body (not shown in the figure) and a door body 30 arranged on the box body, and further comprises the above-mentioned locking device. In the embodiment, a plug hole matched with the plug member 10 can be arranged on the box body of the container. The locking mechanism 20 drives the plug member 10 to extend into or out of the plug hole, so as to lock or unlock the box body and the door body 20.

[0068] Further, the mounting seat 21 is fixed to the inner side of the door body 30. In the embodiment, when the door body 30 is closed, the mounting seat 21 is located in the box body, so as to avoid the damage of the locking mechanism 20 caused by the erosion of the external environment of the box body, and to avoid the damage of the locking mechanism 20 caused by the touch of the locking mechanism 20 from the outside by other persons.

[0069] Specifically, referring to Figure 7 As shown in the figure, the driving member 23 is limitedly arranged between the mounting seat 21 and the door body 30. In the embodiment, the driving plate 23b is limitedly arranged between the locking cover plate 21b and the door body 30, so as to limit the deviation of the driving plate 23b in the direction of the rotation axis of the driving member 23.

[0070] Further, the door body 30 is provided with a lock mounting hole 31 matched with the driving member 23. In the embodiment, the driving member 23 is further provided with an installation boss 23e matched and arranged in the lock mounting hole 31, so that when the driving member 23 rotates, the installation boss 23e is rotationally matched in the lock mounting hole 31, avoiding the deflection of the driving member 23 when rotating, improving the stability of the rotation of the driving member 23, and then improving the stability of the movement of the bolt 10.

[0071] In addition, a lock butt joint sleeve 33 is arranged on the door body 30 outside the lock mounting hole 31, and the butt joint sleeve 33 is provided with a butt joint hole 35, and the installation boss 23e is matched and arranged in the butt joint hole 35. In this way, it is beneficial for the unlocking tool 50 to extend into the unlocking state, and the unlocking tool 50 is stably rotated.

[0072] Further, the container further comprises a sliding sleeve 40 fixed on the door body 30, the bolt 10 comprises a transmission rod 11 matched and arranged in the sliding sleeve 40, an installation plate 13 connected to the end of the transmission rod 11, and a pin rod 15 connected to the installation plate 13 and extending away from the transmission rod 11, the pin rod 15 is uniformly arranged along the length direction of the installation plate 13.

[0073] In the embodiment, one end of the transmission member 27 is hinged to the driving plate 23b, and the other end is hinged to the transmission rod 11, when the driving member 23 rotates, the transmission rod 11 is driven to move linearly in the sliding sleeve 40 through the transmission member 27, and the transmission rod 11 drives the installation plate 13 and the pin rod 15 to move together. The arrangement of the plurality of pin rods 15 improves the connection strength when the door body 30 is locked with the box body.

[0074] Reference Figure 8 As shown in the figure, the preferred embodiment of the present application provides an unlocking tool 50, which comprises a handle 51, a butt joint column 53 connected to the handle 51 and matched with the butt joint hole 35, and an unlocking column 55 connected to the butt joint column 53 and matched with the unlocking hole 23c. Among them, the cross-sectional shape of the butt joint column 53 is circular; the cross-sectional shape of the unlocking column 55 is the same as that of the unlocking hole 23c, which is a multi-rib type, for example, can be a regular quadrilateral.

[0075] In the specific operation, the unlocking column 55 of the unlocking tool 50 is inserted from one side of the docking hole 35, the docking column 53 is first matched with the docking hole 35, and then the unlocking column 55 is matched with the unlocking hole 23c. After the unlocking tool 50 is continuously inserted, the unlocking pin 25e is pressed by the unlocking column 55, the movable part 25b is extruded by the unlocking pin 25e, the elastic part 25d is extruded by the movable part 25b, and the limiting pin 25a is extended out of the first limiting hole 23a or the second limiting hole 23d through the movable part 25b. Then, the driving handle 51 is rotated along the axis of the docking column 53. At this time, since the cross-sectional shape of the unlocking column 55 and the cross-sectional shape of the unlocking hole 23c are both polygonal, the unlocking tool 50 can drive the driving part 23 to rotate. After the driving part 23 is rotated, the bolt part 10 is moved in the slide 40 through the transmission part 27, so that the bolt part 10 is finally inserted into or extended out of the bolt hole arranged on the container, that is, the locking or unlocking of the container door body 30 can be completed.
