Description

Technical Field

[0001] The utility model belongs to the technical field of containers, and in particular relates to a container door lock structure and a container. Background Art

[0002] Existing container door locks mostly use X-shaped locks, which lock the door by inserting the X-shaped locks at both ends of the lock rod into the lock seat at the corresponding position. Due to the structural characteristics of the X-shaped lock, it has a strong limiting ability after matching with the lock seat. However, since the X-shaped lock and the lock seat match closely, not only is the welding positioning of the lock seat required to be high during the installation of the door lock structure, but it is also relatively difficult to open and close under normal use. In addition, if the container is deformed due to welding stress, transportation bumps, etc., the lock rod is pulled or sheared, which can easily cause the X-shaped lock to be stuck with the lock seat, and the door cannot be opened. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a container door lock structure and container which can not only ensure that the door lock structure as a whole has good limiting reliability, but also make the opening and closing of the door lock structure more labor-saving, can play an anti-stuck effect when the box body undergoes a certain degree of deformation, and can reduce the accuracy requirements of welding positioning, thereby improving the installation efficiency.

[0004] The content of the utility model provides a container door lock structure, including a locking rod, a lock head 1 is arranged at one end of the locking rod, and a lock head 2 is arranged at the other end, and also includes a lock seat 1 for cooperating with the lock head 1 and a lock seat 2 for cooperating with the lock head 2. The lock head 1 is an X-shaped lock head, the lock head 2 is arranged horizontally relative to the locking rod and is arc-shaped, and the lock seat 2 includes a support and a limiting column, the two ends of the limiting column are connected to the support, and an active cavity is arranged between the side surface of the limiting column and the support. When the locking rod rotates axially, the lock head 2 moves into the active cavity along the active cavity and hooks on the side surface of the limiting column or moves out along the active cavity, and the size of the active cavity along the axial direction of the locking rod is larger than the size of the lock head 2 along the axial direction of the locking rod.

[0005] Furthermore, the limiting column is cylindrical.

[0006] Furthermore, the support includes a second bottom plate and two fixed plates, the two fixed plates are vertically arranged at both ends of the second bottom plate, the two ends of the limiting column are correspondingly connected to the two fixed plates, and the area between the side of the limiting column and the support and the two fixed plates forms the active cavity.

[0007] Furthermore, one end of the second lock head is connected to the lock rod, and the thickness of the two ends of the second lock head is greater than the thickness of the middle part of the second lock head.

[0008] Furthermore, one end of the second lock head away from the lock rod is arc-shaped.

[0009] Furthermore, the lock seat 1 includes a base plate 1 and a limit block 1, the limit block 1 is vertically arranged on the base plate 1 and is T-shaped, when the lock rod rotates axially, the bayonet on one side of the lock head 1 is stuck between the top of the limit block 1 and the base plate 1.

[0010] Furthermore, the lock seat 1 also includes a limit block 2, which is vertically arranged on the base plate 1 and spaced apart from the limit block 2, and the size of the top of the limit block 2 is not larger than the size of the bottom of the limit block 2. When the lock rod rotates axially, the middle part of the lock head 1 is located between the limit block 1 and the limit block 2, and the bayonet on the other side of the lock head 1 is clamped on the side of the limit block 2.

[0011] Furthermore, it also includes a handle, which is arranged on the locking rod.

[0012] Furthermore, a lock buckle is included for fixing the locking rod.

[0013] The present utility model also provides a container provided with the container door lock structure as described above.

[0014] The beneficial effect of the present utility model is that, under normal use, it can not only ensure that the door lock structure as a whole has good limiting reliability, but also make the rotation of the lock rod easier, and the opening and closing of the door lock structure more labor-saving. When the box body undergoes a certain degree of deformation, a distance margin for preventing jamming can be provided for the door lock structure, thereby preventing the door lock structure from being difficult to open or directly stuck.

[0015] The arc-shaped lock head 1 and lock seat 2 have a relatively simpler structure and lower matching requirements, so the difficulty of production and processing can be reduced, thereby reducing the production cost of the door lock structure. And because a certain margin space can be left between the lock head 2 and the lock seat 2 in the axial direction of the lock rod, the position accuracy between the lock seat 1 and the lock seat 2 can be relaxed, so the accuracy requirements for welding positioning can be reduced, and the installation efficiency can be improved.

[0022] like Figure 1-Figure 5 As shown, the utility model provides a container door lock structure, including a lock rod 1, a lock seat 1 4 and a lock seat 2 5. The lock rod 1 is provided with a lock head 1 2 at one end and a lock head 2 3 at the other end. The lock head 1 2 and the lock head 2 3 rotate with the lock rod 1. The lock seat 1 4 is used to cooperate with the lock head 1 2, and the lock seat 2 5 is used to cooperate with the lock head 2 3. The lock head 1 2 is preferably an X-shaped lock head, such as Figure 2 As shown, two blocks are arranged on each side of the X-shaped lock head, and the four blocks together form an approximate X shape, so it is an X-shaped lock head, and a bayonet is formed between the two blocks on one side of the X-shaped lock head. The lock head 2 3 is arranged horizontally relative to the lock rod 1, and the lock head 2 3 is arc-shaped and hook-shaped. The lock seat 2 5 includes a support and a limiting column 53, and the two ends of the limiting column 53 are connected to the support. An active cavity 54 for the lock head 2 3 to move in and out is arranged between the side of the limiting column 53 and the support, and in the installed state, the limiting column 53 and the lock rod 1 are arranged in parallel. When the lock rod 1 rotates around its own axis, the lock head 2 3 moves into the active cavity 54 along the rotation of the lock rod 1 and hooks on the side of the limiting column 53 or moves out along the active cavity 54, and the size of the active cavity 54 along the axial direction of the lock rod 1 is larger than the size of the lock head 2 3 along the axial direction of the lock rod 1.

[0023] The container door lock structure provided by the utility model has different lock heads at both ends of the lock rod 1, specifically, an X-shaped lock head structure is adopted at one end, and an arc-shaped lock head is adopted at the other end. When applied to a container, a lock seat 1 4 and a lock seat 2 5 are arranged on the container body 100, and the lock rod 1 is rotatably arranged on the container door 200. In the locked state, the lock head 1 2 is clamped into the lock seat 1 4, and the lock head 2 3 is clamped into the lock seat 2 5, so as to realize the closing between the container door 200 and the container body 100. The lock head 1 2 of the X-shaped lock head can provide a strong limiting ability for the door lock structure as a whole due to its own structural characteristics, and ensure the limiting reliability of the door lock structure as a whole. The arrangement of the arc-shaped lock head 2 3, the movable cavity 54 and the limiting column 53 makes the rotation process smoother when the end of the lock rod 1 basically meets the limiting requirements, and can leave a certain margin space between the lock head 2 3 and the lock seat 2 5 in the axial direction of the lock rod 1. Under normal use, it can not only ensure that the door lock structure as a whole has good limiting reliability, but also make the rotation of the lock rod 1 easier, and the opening and closing of the door lock structure is more labor-saving. Based on the arrangement of the aforementioned margin space, when the box body 100 undergoes a certain deformation degree range, an anti-stuck distance margin can be provided for the door lock structure to avoid the door lock structure being difficult to open or directly stuck. Among them, the size of the residual space between the lock head 2 3 and the lock seat 2 5 is determined according to the actual deformation that often occurs in the box body 100. When the deformation of the box body 100 exceeds the range that can be compensated by the residual space between the lock head 2 3 and the lock seat 2 5, the box door 200 is opened according to the actual specific situation, for example, by removing the door lock structure.

[0024] The arc-shaped lock head 1 2 and lock seat 2 5 have a relatively simpler structure and lower matching requirements, so the difficulty of production and processing can be reduced, thereby reducing the production cost of the door lock structure. And because a certain margin space can be left between the lock head 2 3 and the lock seat 2 in the axial direction of the lock rod 1, the position control accuracy between the lock seat 1 4 and the lock seat 2 5 can be relaxed, so the accuracy requirements for welding positioning can be reduced, and the installation efficiency can be improved.

[0025] Preferably, the limiting column 53 is cylindrical, and in the installed state, its axis is parallel to the axis of the lock rod 1. Compared with other shapes, the cylindrical limiting column 53 can further make the rotation of the lock head 2 3 along the side of the limiting column 53 smoother.

[0026] The support specifically includes a bottom plate 51 and two fixing plates 52. The two fixing plates 52 are vertically arranged at both ends of the bottom plate 51. The two ends of the limiting column 53 are correspondingly connected to the two fixing plates 52. Figure 4As shown, the limiting column 53 is suspended relative to the bottom plate 2 51, and the area between the side of the limiting column 53 and the support and the two fixed plates 52 forms the movable cavity 54. The axial dimension of the portion of the limiting column 53 located between the two fixed plates 52 is the same as the axial dimension of the movable cavity 54. In this arrangement, the bottom plate 2 51 can be used as a mounting seat for the lock seat 2 5, and can also connect the two fixed plates 52 to ensure the structural strength of the lock seat 2 5. The size of the movable cavity 54 is determined according to the actual size of the lock head 2 3, and it is sufficient to move the lock head 2 3 in and out when it rotates. In the installed state, the lock seat 2 5 is located on the side of the lock rod 1, as shown in FIG. Figure 5 As shown, at this time, the lock head 3 passes through the active cavity 54 and is hooked on the limiting column 53. In this perspective, the lock head 3 can be moved out along the active cavity 54 by rotating the lock rod 1 counterclockwise to separate the lock head 3 and the lock seat 2 5. The width of the bottom plate 2 51 and the two fixing plates 52 can be set to be narrower so that the lock rod 1 can be Figure 5 After the viewing angle is rotated counterclockwise by a certain angle (for example, within a range not greater than 90°), the second lock head 3 is completely moved out of the movable cavity 54, so that the rotation of the lock rod 1 can simultaneously accommodate the movement in and out of the first lock head 2 and the second lock head 3.

[0027] One end of the lock head 3 is connected to the lock rod 1, and the thickness of the two ends of the lock head 3 is greater than the thickness of the middle part of the lock head 3. In this arrangement, the end of the lock head 3 connected to the lock rod 1 and the hook-shaped end of the lock head 3 are thicker, which can increase the connection strength between the lock head 3 and the lock rod 1, and increase the reliability of the lock head 3 when hooking the limit column 53.

[0028] Preferably, the end of the lock head 3 away from the lock rod 1 is arc-shaped, that is, Figure 3 and Figure 5 As shown, the hook-shaped end of the lock head 2 3 is arc-shaped, which is beneficial to improving the smoothness of the rotation of the lock head 2 3 .

[0029] like Figure 2 As shown, the lock seat 14 includes a bottom plate 141 and a limit block 142. The limit block 142 is vertically arranged on the bottom plate 141 and is T-shaped. When the lock rod 1 rotates axially, the bayonet on one side of the lock head 2 is clamped between the top of the limit block 142 and the bottom plate 141, specifically, clamped on the T-shaped vertical part of the limit block 142. The T-shaped vertical part of the limit block 142 can limit the lock head 2 in the axial direction of the lock rod 1, and the T-shaped horizontal part of the limit block 142 can limit the lock head 2 in the height direction of the limit block 142, thereby ensuring the reliability of the limit. Among them, the height dimension of the T-shaped vertical part of the limit block 142 is determined according to the size of the two clamping blocks on the side of the lock head 2, and the distance between the T-shaped horizontal part of the limit block 142 and the bottom plate 141 is sufficient for the two clamping blocks on the side of the lock head 2 to rotate freely.

[0030] The lock base 1 4 also includes a limit block 2 43, which is vertically arranged on the bottom plate 1 41 and spaced from the limit block 2 43, and the size of the top of the limit block 2 43 is not greater than the size of the bottom of the limit block 2 43. In the installed state, the middle of the lock head 1 2 is located between the limit block 1 42 and the limit block 2 43, and the bayonet on the other side of the lock head 1 2 is clamped on the side of the limit block 2 43, so as to limit the lock head 1 2 in the direction of the connection between the limit block 1 42 and the limit block 2 43, further ensuring its limit reliability. Figure 2 As shown, this is a schematic diagram of the state after the lock head 2 and the lock seat 4 are matched. From this perspective, the lock rod 1 is rotated counterclockwise to make the two blocks on the right side of the lock head 2 withdraw from the limit block 1 42 and the two blocks on the left side withdraw from the limit block 2 43, and then the lock head 2 and the lock seat 4 can be separated.

[0031] The utility model further includes a handle 6, which is arranged on the lock rod 1 to facilitate the rotation of the handle 6. The utility model further includes a lock buckle 7, which is used to lock the position of the lock rod 1. The lock buckle 7 is specifically a prior art, and its structure is not repeated. The lock buckle 7 is arranged on the door 200 in the installed state, and is used to buckle the handle 6 after the lock head 2 cooperates with the lock seat 1 4, and the lock head 2 3 cooperates with the lock seat 2 5, so as to fix the lock rod 1 and lock its position, so that the lock rod 1 will not rotate autonomously due to the movement of the container.

[0032] The utility model also provides a container, which is provided with the container door lock structure as described above. The container includes a box body 100 and a door 200, the door 200 is hingedly arranged on the door 200, a lock seat 1 4 and a lock seat 2 5 are arranged at the upper and lower ends of one side of the box body 100 where the door 200 is arranged, a lock rod 1 is rotatably arranged on the door 200 through a mounting seat, a lock catch 7 is arranged on the door 200 and is located on one side of the lock catch 1, and the position of the lock catch 7 corresponds to the position of the handle 6. The number of container door lock structures corresponds to the number of door 200. When the number of door 200 is one, the number of container door lock structures corresponds to one. Figure 1 As shown, when the number of container doors 200 is two, the number of container door lock structures is correspondingly two.

[0033] Since the container door lock structure is provided, under normal use, the door lock structure as a whole can be guaranteed to have good position-limiting reliability, and the rotation of the lock rod 1 can be made easier, the door lock structure can be opened and closed more labor-saving, and when the box body 100 is deformed within a certain range, a distance margin can be provided for the door lock structure to prevent it from being difficult to open or directly stuck. And since a certain margin space can be reserved between the lock head 2 3 and the lock seat 2 in the axial direction of the lock rod 1, the position control accuracy between the lock seat 1 4 and the lock seat 2 5 can be relaxed, so the accuracy requirements for welding positioning can be reduced, and the installation efficiency can be improved.
