The second locking bar 120 includes a second connection end 121, the second connection end 121 is provided with a second external thread 123, and the second external thread 123 is opposite to the first external thread 113. The transmission sleeve 130 is used for connecting the first connection end 111 and the second connection end 121, and the axial direction of the transmission sleeve 130 is the same as the axial direction of the first lock lever 110 and the second lock lever 120. The transmission sleeve 130 is internally provided with an internal thread matched with the first external thread 113 and the second external thread 123, and the first connection end 111 and the second connection end 121 are connected with the transmission sleeve 130 in a threaded manner, so that the first lock rod 110 and the second lock rod 120 are connected with the transmission sleeve 130 in a threaded manner. The operating member 140 is connected to the transmission sleeve 130, and the operating member 140 is rotatable and can drive the transmission sleeve 130 to rotate. The rotation of the transmission sleeve 130 may drive the first external thread 113 and the second external thread 123 to rotate relative to the internal thread of the transmission sleeve 130, so that the first locking rod 110 and the second locking rod 120 perform linear motion in opposite directions along the axial direction of the transmission sleeve 130, so as to move between a locking position for locking a door of a container and an unlocking position for unlocking the door of the container.

According to the container locking device 100 of the present invention, the first locking rod 110 and the second locking rod 120 are in threaded connection with the transmission sleeve 130 through the first external thread 113 and the second external thread 123 with opposite rotation directions, the transmission sleeve 130 can be driven to rotate by rotating the operating member 140, and the first locking rod 110 and the second locking rod 120 are further driven to move in opposite directions along the axial direction of the transmission sleeve 130, so as to move between the locking position and the unlocking position, thereby locking and unlocking the container door of the container, and the operation is simple and fast, and time and labor are saved.

In the embodiment shown in fig. 1, the operating member 140 is configured in an elongated structure to facilitate operation by an operator. The operating member 140 is preferably connected substantially perpendicularly to the transmission sleeve 130, and the operating member 140 can rotate in a plane perpendicular to the axial direction of the transmission sleeve 130 by any angle between 0 and 180 ° and can bring about the rotation of the transmission sleeve 130. By providing the rotational directions of the first and second external threads 113 and 123, the first and second lock levers 110 and 120 are respectively moved to the locking position in their own axial directions when the operating member 140 is rotated in a certain predetermined direction, and the first and second lock levers 110 and 120 are respectively moved to the unlocking position in their own axial directions when the operating member 140 is rotated in a direction opposite to the above-mentioned predetermined direction. The operating member 140 and the transmission sleeve 130 may be fixedly connected by a connection manner such as welding, etc. to ensure that the transmission sleeve 130 can rotate synchronously with the operating member 140, improve transmission efficiency therebetween, and ensure stability of movement of the first and second lock levers 110 and 120 between the unlocking position and the locking position.

In the embodiment shown in fig. 1, the pitch of the first external thread 113 and the second external thread 123 is substantially the same. In the actual design process, the thread pitches of the first external thread 113 and the second external thread 123 may be different, specifically, determined according to the relationship between the stroke of the first locking lever 110 and the second locking lever 120 between the locking position and the unlocking position and the rotation angle of the operating member 140.

The container is usually provided with a locking groove corresponding to the container locking device 100, for example, the locking groove may be provided on the door frame of the container. Preferably, the door frame may comprise a door lintel 311 and a door sill 312, the door lintel 311 being arranged above the door sill 312 in the height direction of the container, with particular reference to fig. 1. The door lintel 311 may be provided with a locking slot, and the container locking device 100 may be cooperatively coupled with the locking slot to facilitate locking of the upper portion of the door. The threshold 312 may be provided with a locking groove, and the container locking device 100 may be coupled with the locking groove to lock the lower portion of the door.

Specifically, the first locking bar 110 includes a first free end 112, the second locking bar 120 includes a second free end 122, a door lintel 311 of the container is provided with a first locking groove 313 matched with the first free end 112, and a door sill 312 of the container is provided with a second locking groove 314 matched with the second free end 122. In the state where the first and second locking levers 110 and 120 are in the locking position, the first and second free ends 112 and 122 are located in the first and second locking grooves 313 and 314, respectively; in the state where the first and second levers 110 and 120 are in the unlock position, the first and second free ends 112 and 122 are located outside the first and second lock grooves 313 and 314, respectively.

Preferably, the first locking groove 313 includes a first cylindrical portion 313a and a first inclined portion 313b communicating with each other, and the first inclined portion 313b is closer to the locking bar than the first cylindrical portion 313a in the axial direction of the first locking bar 110. When the first latch 110 is in the locking position, the first free end 112 is at least partially located in the first column portion 313a to fix the first latch 110.

The first inclined portion 313b is preferably configured to be inclined in a direction away from the first cylindrical portion 313a in a direction from the first cylindrical portion 313a to the first locking bar 110. That is, the cross-sectional area of the first inclined portion 313b is gradually reduced from the bottom end of the first inclined portion 313b to the top end of the first inclined portion 313b in the axial direction of the first lock lever 110 to guide the first lock lever 110 so that the first free end 112 enters and exits the first cylindrical portion 313a during the movement of the first lock lever 110 between the locking position and the unlocking position.

Likewise, the second locking groove 314 includes a second cylindrical portion 314a and a second inclined portion 314b communicating with each other. The second columnar portion 314a and the second inclined portion 314b have the same structural form, connection manner, and function as those of the first columnar portion 313a and the first inclined portion 313 b.

Preferably, a first guide portion 112a is provided at an end portion of the first free end 112, and the first guide portion 112a is configured substantially in a circular truncated cone structure, that is, a diameter of the first guide portion 112a gradually decreases from a bottom end of the first guide portion 112a to a top end of the first guide portion 112a, so that the first free end 112 enters and exits the first column portion 313a during movement of the first lock lever 110 between the locking position and the unlocking position.

Similarly, a second guide portion 122a is provided at an end portion of the second free end 122, and the second guide portion 122a has the same configuration and function as the first guide portion 112 a.

In the present embodiment, the axial direction of the first and second lock bars 110 and 120 is parallel to the height direction of the container. Of course, the axial directions of the first and second lock bars 110 and 120 may also be parallel to the width direction (length direction) of the container, and the present invention is not limited thereto. The first and second locking bars 110 and 120 are movable in the axial direction of the locking bars so as to be able to enter into or separate from the locking groove.

Preferably, the first locking rod 110, the second locking rod 120 and the transmission sleeve 130 may be disposed at an inner side of a door of the container, and the operating member 140 may be disposed at an outer side of the door, e.g., the operating member 140 may extend through the door to the outside of the container. An operator can control the operating member 140 outside the container to unlock or lock the door, so that the influence of severe environment or external impact on the first lock rod 110, the second lock rod 120 and the transmission sleeve 130 can be effectively reduced, and the service life of the container locking device 100 can be prolonged.

In order to ensure that the first and second lock bars 110 and 120 can be accurately inserted into the first and second lock grooves 313 and 314, the container locking device 100 further includes a lock bar guide 160, and the cross-sectional shape of the lock bar guide 160 may be U-shaped for guiding the movement of the first and second lock bars 110 and 120. Alternatively, the locking bar guide 160 may be disposed on an inner surface of the door, and a locking bar guide chamber 161 may be formed between the locking bar guide 160 and the inner surface of the door to receive the first locking bar 110 and the second locking bar 120 and prevent the first locking bar 110 and the second locking bar 120 from being deviated when moving.

Further, in order to ensure that the first latch bar 110 can move in a straight line, as shown in fig. 3 and 4, the first latch bar 110 has a first latch bar plane 171. The first lock lever plane 171 is cut from the outer circumferential surface of the first lock lever 110. The container locking apparatus includes the first locking bar guide 172, that is, the locking bar guide 160 includes the first locking bar guide 172, as shown in fig. 5 and 6, the first locking bar guide 172 may be fixedly coupled with the door 300. The first lock lever guide 172 and the door 300 together form a space for receiving the first lock lever 110. A portion of the first lock lever 110 is located in the first lock lever guide 172, and the first lock lever 110 extends beyond the first lock lever guide 172. The first locking bar guide 172 can abut against the first locking bar 110 so that the first locking bar 110 can linearly move in the height direction of the container with respect to the first locking bar guide 172. The height direction of the container is substantially parallel to the axial direction of the first lock lever 110.

As shown in fig. 6, the first locking lever guide 172 has a first guide plane 173, and the first guide plane 173 is located inside the first locking lever guide 172. The first guide plane 173 faces the first lock lever 110, and the first guide plane 173 abuts against the first lock lever 110, so that the first guide plane 173 restricts the first lock lever 110 and prevents the first lock lever 110 from rotating along with the rotation of the operating member 140. The first guide plane 173 abuts against the first lock lever plane 171, and the first guide plane 173 restricts the first lock lever plane 171 to prevent the first lock lever plane 171 from rotating around the axial direction of the first lock lever 110, and further prevent the first lock lever 110 from rotating around the axial direction of the first lock lever 110. The first lock bar 110 is closely attached to the door 300, the door 300 abuts against the first lock bar 110, and the door 300 can restrain the first lock bar 110 to prevent the first lock bar 110 from rotating around the axial direction of the first lock bar 110.

Referring to fig. 1, the operating member 140 rotates around the axial direction of the first lock lever 110, and the transmission sleeve 130 is fixedly connected to the operating member 140. The operating member 140 rotates the transmission sleeve 130 about the axial direction of the first lock lever 110. The first locking lever 110 has a first external thread 113, and a driving sleeve 130 has an internal thread formed therein, the first external thread 113 being engaged with the internal thread. The transmission sleeve 130 rotates and the first lock lever guide 172 restrains the first lock lever 110. The first guide plane 173 and the first latch lever plane 171 cooperate to restrict the rotation of the first latch lever 110. The first guide plane 173 can prevent the first lock lever 110 from rotating about the axial direction of the first lock lever 110, thereby allowing the first lock lever 110 to move in the axial direction of the first lock lever 110 when the transmission sleeve 130 rotates.

In the embodiment shown in fig. 5, the first latch bar 110 has at least two first latch bar planes 171, and two of the at least two first latch bar planes 171 are oppositely arranged in a radial direction of the first latch bar 110. The first locking bar guide 172 may have at least two first guide planes 173, and two of the at least two first guide planes 173 are oppositely disposed in a radial direction of the first locking bar 110. Thus, the two first lock lever planes 171 can respectively abut against the two first guide planes 173 to enhance the constraint of the first lock lever 110 by the first lock lever guide 172. A narrow space may be left between the first locking bar plane 171 and the first guide plane 173 to facilitate assembly. Of course, the size of the space in the radial direction of the first lock lever 110 does not cause the first lock lever 110 to rotate in the first lock lever guide 172.

Similarly, in order to ensure that the second lock lever 120 can move in a straight line, as shown in fig. 7 and 8, the second lock lever 120 has a second lock lever plane 174. The second locking bar plane 174 is cut from the outer circumferential surface of the second locking bar 120. The container locking apparatus includes the second locking bar guide 175, that is, the locking bar guide 160 includes the second locking bar guide 175, and as shown in fig. 9 and 10, the second locking bar guide 175 may be fixedly coupled with the door 300. The second locking bar guide 175 and the door 300 together form a space for receiving the second locking bar 120. A portion of the second locking bar 120 is located in the second locking bar guide 175 and the second locking bar 120 extends beyond the second locking bar guide 175. The second locking bar guide 175 can abut against the second locking bar 120 so that the second locking bar 120 can be linearly moved in the height direction of the container with respect to the second locking bar guide 175. The height direction of the container is substantially parallel to the axial direction of the second lock bar 120.

As shown in fig. 10, the second locking bar guide 175 has a second guide plane 176, and the second guide plane 176 is located inside the second locking bar guide 175. The second guiding plane 176 faces the second locking bar 120, and the second guiding plane 176 abuts against the second locking bar 120, so that the second guiding plane 176 has a restraining effect on the second locking bar 120. The second guide plane 176 and the second locking lever plane 174 cooperate to restrict the rotation of the second locking lever 120 and prevent the second locking lever 120 from rotating as the operating member 140 rotates. The second guide plane 176 abuts against the second locking bar plane 174, and the second guide plane 176 restricts the second locking bar plane 174 to prevent the second locking bar plane 174 from rotating around the axial direction of the second locking bar 120, and further prevent the second locking bar 120 from rotating around the axial direction of the second locking bar 120. The second lock rod 120 is further closely attached to the door 300, the door 300 abuts against the second lock rod 120, and the door 300 can restrain the second lock rod 120 to prevent the second lock rod 120 from rotating around the axial direction of the second lock rod 120.

Referring to fig. 1, the operating member 140 rotates around the axial direction of the second lock lever 120, and the transmission sleeve 130 is fixedly connected to the operating member 140. The operating member 140 rotates the transmission sleeve 130 about the axial direction of the second lock lever 120. The second locking lever 120 has a second external thread 123, and a driving sleeve 130 has an internal thread formed therein, and the second external thread 123 is engaged with the internal thread. The transmission sleeve 130 rotates and the second locking lever guide 175 restrains the second locking lever 120, and the second guide plane 176 can prevent the second locking lever 120 from rotating about the axial direction of the second locking lever 120, thereby allowing the second locking lever 120 to move in the axial direction of the second locking lever 120 when the transmission sleeve 130 rotates.

In the embodiment shown in fig. 9, the second lock lever 120 has at least two second lock lever planes 174, and two of the at least two second lock lever planes 174 are oppositely arranged in a radial direction of the second lock lever 120. The second locking bar guide 175 may have at least two second guide planes 176, and two of the at least two second guide planes 176 are oppositely disposed in a radial direction of the second locking bar 120. Thus, the two second locking bar planes 174 can respectively abut against the two second guide planes 176 to enhance the constraint of the second locking bar 120 by the second locking bar guide 175. A narrow space may be left between the second locking bar plane 174 and the second guide plane 176 to facilitate assembly. Of course, the space has a size in the radial direction of the second lock lever 120 such that the second lock lever 120 does not rotate in the second lock lever guide 175.

In an embodiment not shown in the drawings, the first and second lock bars 110 and 120 may further have elongated grooves, and the elongated grooves may extend in a direction substantially parallel to the height direction of the container. The elongated groove may be recessed inward from an outer surface of the first locking bar. The elongated groove may be recessed inward from an outer surface of the second locking bar. The height direction of the container is substantially parallel to the axial direction of the first lock lever 110. The locking bar guide may be further provided with a protrusion portion protruding from an inner surface of the locking bar guide toward the locking bar. The protrusion may be inserted into the elongated groove, the first lock bar 110 may not rotate around the axial direction of the first lock bar 110, and the second lock bar 120 may not rotate around the axial direction of the second lock bar 120, so as to ensure that both the first lock bar 110 and the second lock bar 120 can linearly move along the height direction of the container. Of course, the first and second locking levers 110 and 120 may have protrusions and the locking lever guide may have elongated grooves. The elongated slot may be recessed from the inner surface of the locking bar guide in a direction away from the locking bar. In this way, the locking rod guide may also respectively play a role in restraining the first locking rod 110 and the second locking rod 120, preventing the first locking rod 110 and the second locking rod 120 from rotating, and ensuring that both the first locking rod 110 and the second locking rod 120 can move linearly in the height direction of the container. The length of the elongated slot can also play a role in positioning the distance that the first lock rod 110 and the second lock rod 120 move linearly along the height direction of the container, so as to prevent the first lock rod 110 and the second lock rod 120 from moving excessively.

Preferably, as shown in fig. 11, the container locking device may further include a driving sleeve 177, and the driving sleeve 177 is constructed in a tubular structure. The axial direction of the transmission sleeve 177 may be substantially parallel to the axial direction of the first and second lock rods 110 and 120. The transmission sleeve 177 is adapted to be fixedly coupled to the door 300, i.e., the transmission sleeve 177 is not rotatable relative to the door 300. The transmission sleeve 177 is sleeved on the transmission sleeve 130. The drive sleeve 130 may rotate within the drive sleeve 177 relative to the drive sleeve 177. The drive sleeve 177 has an inner peripheral surface 178, the inner peripheral surface 178 mating with an outer peripheral surface of the drive sleeve 130. The drive sleeve 130 extends through the drive sleeve 177, and an outer peripheral surface of the drive sleeve 130 is substantially parallel to the inner peripheral surface 178. Thus, the transmission sleeve 130 rotates in the transmission sleeve 177, and the transmission sleeve 130 is prevented from moving in the horizontal direction, so that the transmission sleeve 130 is prevented from moving horizontally in the direction away from the box door 300 along the horizontal direction, the stability is enhanced, and the safety is improved.

Referring to fig. 2, there is shown a container locking device 200 according to a second preferred embodiment of the present invention. The structure of the container locking device 200 of the second preferred embodiment is similar to that of the first preferred embodiment, and the differences will be described below, and the description of the similar parts will not be repeated.

The container locking device 200 according to the present embodiment includes a transmission device 150, the transmission device 150 is used to connect the transmission sleeve 130 and the operating member 140, and the operating member 140 drives the transmission sleeve 130 to rotate through the transmission device 150.

Specifically, the transmission 150 includes a first gear 151 and a second gear 152. The first gear 151 is disposed on the transmission sleeve 130, preferably in the middle of the transmission sleeve 130, and can be fixedly connected to the transmission sleeve 130. The second gear 152 is connected with the operating member 140 and is engaged with the first gear 151. The axial direction of the second gear 152 is substantially perpendicular to the axial direction of the transmission sleeve 130. The operating member 140 is rotatable in a plane perpendicular to the axial direction of the second gear 152, and drives the second gear 152 to rotate, and further drives the first gear 151 and the transmission sleeve 130 to rotate through the second gear 152, so that the first lock lever 110 and the second lock lever 120 linearly move in opposite directions along the axial direction of the transmission sleeve 130 to move between a locking position for locking the doors of the container and an unlocking position for unlocking the doors of the container.

Preferably, the transmission 150 further includes a rotating shaft 153, and one end of the rotating shaft 153 is connected with the operating member 140, preferably substantially perpendicularly to one end of the operating member 140, so as to be conveniently operated by an operator. The two may be joined together, such as by welding. The other end of the shaft 153 is connected to the second gear 152 and may be connected together by welding, for example. The axial direction of the rotation shaft 153 is parallel to the axial direction of the second gear 152 and perpendicular to the axial direction of the transmission sleeve 130. This connection allows the operating member 140 to rotate in a plane perpendicular to the rotating shaft 153 by any angle between 0-360 degrees, and the first gear 151 and the second gear 152 can drive the transmission sleeve 130 to rotate, thereby driving the first lock lever 110 and the second lock lever 120 to move between the open position and the locked position. The strokes of the first and second lock levers 110 and 120 and the pitch designs of the first and second external threads 113 and 123 are no longer affected by the rotation angle of the operating member 140, effectively increasing the design space of the first and second external threads 113 and 123. Preferably, the rotation shaft 153 is connected to a central position of the second gear 152 so as to control the rotation of the second gear 152 by the operating member 140.

The first gear 151 and the second gear 152 are preferably each configured as helical gears to improve transmission efficiency, smoothness of transmission, and load-bearing capacity of the transmission.

Likewise, the first gear 151 and the second gear 152 may be disposed at an inner side of a door of the container, and the operating member 140 may be disposed at an outer side of the door. The door is correspondingly provided with a hole (not shown) of the rotating shaft 153, and the axial direction of the hole of the rotating shaft 153 is the thickness direction of the door, in other words, the axial direction of the hole of the rotating shaft 153 is parallel to the axial direction of the rotating shaft 153. The shaft 153 extends through the shaft 153 hole and is rotatable in the shaft 153 hole.

Preferably, the transmission device 150 further includes a guide sleeve 154, and the guide sleeve 154 is sleeved on the rotating shaft 153 to support the rotating shaft 153 and protect the rotating shaft 153. The shaft 153 is rotatable in the guide sleeve 154. A corresponding hole (not shown) of the guide bushing 154 is disposed on the door, so that the guide bushing 154 passes through the door and extends to the outside of the door.

In an embodiment, which is not shown, the transmission device 150 may be configured as a bidirectional ratchet device, and the operating member 140 drives the transmission sleeve 130 to rotate through the bidirectional ratchet device, and further drives the first lock rod 110 and the second lock rod 120 to move linearly in opposite directions along the axial direction of the transmission sleeve 130 to move between a locking position for locking the door of the container and an unlocking position for unlocking the door of the container. The operating member 140 and the transmission sleeve 130 are connected by a bidirectional ratchet device, and the operating member 140 can be repeatedly rotated to increase the strokes of the first lock rod 110 and the second lock rod 120, so that the strokes of the first lock rod 110 and the second lock rod 120 and the pitches of the first external thread 113 and the second external thread 123 are no longer influenced by the rotation angle of the operating member 140, and the design space of the first external thread 113 and the second external thread 123 can be effectively increased. The two-way ratchet device is a conventional two-way ratchet device, and the structural form thereof is not particularly limited.
