The existing container lock structure includes a chassis, and the chassis includes two relatively arranged bottom side beams. A notch is provided on the inner side of the bottom side beam for accommodating the twist lock. However, the above container lock structure has low strength, resulting in a shortened service life. Summary of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a container lock structure and a container that can improve the structural strength.

[0004] To achieve the above purpose, the embodiments of the utility model adopt the following technical solutions:

[0005] A container lock structure includes a chassis and a turn-lock assembly installed on the chassis;

[0006] The chassis includes two bottom side beams and two bottom cross beams. The two bottom side beams are relatively arranged and extend along the longitudinal length of the container. The two bottom side beams both have inner side walls close to each other. The two bottom cross beams are fixed between the inner side walls of the two bottom side beams and are distributed along the longitudinal length;

[0007] The turn-lock assembly includes a connecting plate and a turn-lock plate. The connecting plate is fixed between the two bottom cross beams, and its outer side is fixedly connected to the inner side wall of the bottom side beam. The turn-lock plate is fixed to the bottom of the connecting plate and is fixedly connected to the bottom side beam and the two bottom cross beams, so that the turn-lock plate, the bottom side beam, the two bottom cross beams and the connecting plate enclose a lock space for accommodating the twist lock. A lock hole communicating with the lock space is opened upward on the bottom surface of the turn-lock plate.

[0008] Further, the connecting plate has a vertical plate, the top end of the vertical plate bends and extends outward to form a top plate, the free end of the top plate is fixedly connected to the inner side wall of the corresponding bottom side beam, and the turn-lock plate is fixed to the bottom surface of the vertical plate.

[0009] Further, the vertical plate is perpendicular to the top plate, the free end of the top plate is fixedly connected to the inner side wall of the bottom side beam by welding, and the turn-lock plate is welded to the bottom surface of the vertical plate.

[0010] Further, an observation hole is formed inwards on the outer side wall of the bottom side beam corresponding to the lock space. The observation hole communicates with the lock space, and a reinforcing plate is fixed to the inner wall of the observation hole.

[0011] Further, a through hole is formed inwards on the outer side wall of the bottom side beam corresponding to the rotary lock plate. The outer side of the rotary lock plate extends out of the outer side wall of the bottom side beam from the through hole.

The rib plate corresponds to the lock space, and a mounting hole is formed inwards on its outer plate surface corresponding to the observation hole. The mounting hole communicates with the observation hole.

[0013] Further, the mounting hole extends downwards to the top surface of the rotary lock plate. When viewed in the direction perpendicular to the outer side wall of the bottom side beam, the projected area of the mounting hole is larger than the projected area of the observation hole. The reinforcing plate is C-shaped and its outer end extends outwards from the mounting hole to the outer side wall of the rib plate.

[0014] The container lock structure of the present utility model forms a stable structure to improve the structural strength by arranging a connecting plate fixed between two bottom cross beams, the outer side of the connecting plate is fixedly connected to the inner side wall of the bottom side beam, and arranging a rotary lock plate fixed to the bottom of the connecting plate and fixedly connected to the bottom side beam and the bottom cross beams. The rotary lock plate, the bottom side beam, the two bottom cross beams and the connecting plate enclose a lock space for accommodating a twist lock.

The container lock structure of the present utility model has the characteristics of high strength and easy installation.

[0015] An embodiment of the present utility model further provides a container, including the container lock structure described in any one of the above embodiments. Description of the Drawings

[0019] Figure 4 isFigure 3 Partial enlarged view of C Specific embodiments

[0020] Next, in combination with the accompanying drawings and specific embodiments, the present utility model will be further described:

[0021] As Figures 1 to 4 shown, an embodiment of the present utility model provides a container lock structure, which is installed on a container 100 and includes a chassis 1 and a turn-lock assembly 2 installed on the chassis 1. The container 100 defines a transverse direction Y and a longitudinal direction X perpendicular to the transverse direction Y.

[0022] As Figures 1 to 3 shown, the chassis 1 includes two bottom side beams 11 and two bottom cross beams 12. The two bottom side beams 11 are arranged oppositely and extend along the longitudinal direction X. The two bottom side beams 11 are parallel and each has an inner side wall 111 close to each other. The two bottom cross beams 12 are fixed by welding between the inner side walls 111 of the two bottom side beams 11 and are distributed along the longitudinal direction X. Specifically, the two bottom cross beams 12 are parallel and extend along the transverse direction Y.

[0023] As Figure 2 、 Figure 3 shown, the turn-lock assembly 2 includes a connecting plate 21 and a turn-lock plate 22 for supporting a twist lock (not shown). The connecting plate 21 is fixed between the two bottom cross beams 12, and its outer side is fixedly connected to the inner side wall 111 of the bottom side beam 11. The turn-lock plate 22 is fixed to the bottom of the connecting plate 21 and is fixedly connected to the bottom side beam 11 and the two bottom cross beams 12, so that the turn-lock plate 22 and the bottom side beam 11, the two bottom cross beams 12 and the connecting plate 21 enclose a lock space 3 for accommodating a twist lock (not shown) and form a stable structure to improve the structural strength. Moreover, a lock hole 221 communicating with the lock space 3 is opened upward on the bottom surface of the turn-lock plate 22, and it is not necessary to directly open the lock hole 221 on the bottom side beam 11, further improving the structural strength and achieving the purpose of extending the service life. When the container 100 is locked with a transport vehicle, the self-locking hole 221 of the twist lock of the transport vehicle is inserted upward into the lock space 3, and then rotated by an angle until it reaches the locked position. At this time, the turn-lock plate 22 supports the lock head of the twist lock, that is, the lock head hangs on the turn-lock plate 22. When unlocking, the twist lock rotates reversely by an angle until it is aligned with the lock hole 221, and then extends downward from the lock hole 221 out of the turn-lock plate 22, and at this time the unlocking is completed.

[0024] As Figure 2 、<m Figure 3As shown in the figure, the connecting plate 21 has a vertical plate 211. The top end of the vertical plate 211 extends integrally and bends outward to form a top plate 212. The free end of the top plate 212 is fixedly connected to the inner side wall 111 of the corresponding bottom side beam. The turn-lock plate 22 is fixed to the bottom surface of the vertical plate 211. Specifically, the vertical plate 211 is perpendicular to the top plate 212, and the free end of the top plate 212 is fixedly connected to the inner side wall 111 of the bottom side beam by welding. The turn-lock plate 22 is welded to the bottom surface of the vertical plate 211. The structure and processing technology of this connecting plate 21 are simple, which can reduce the production cost.

[0025] As Figures 2 to 4 shown, in order to facilitate observing the turn-lock state in the lock space 3, an observation hole 112 is opened inward on the outer side wall of the bottom side beam 11 corresponding to the lock space 3. The observation hole 112 communicates with the lock space 3, and a reinforcing plate 113 is fixed to the inner wall of the observation hole 112. The reinforcing plate 113 can enhance the structural strength of the bottom side beam 11. For the convenience of installation and further enhancing the structural strength, specifically, a through hole 114 is opened inward on the outer side wall of the bottom side beam 11 corresponding to the turn-lock plate 22. The outer side of the turn-lock plate 22 extends out of the outer side wall of the bottom side beam 11 from the through hole 114. The observation hole 112 is located above the through hole 114 and extends downward to the through hole 114 to communicate with the through hole 114. The top and bottom of the reinforcing plate 113 are respectively welded to the top wall of the observation hole 112 and the top surface of the connecting plate 21, and the outer side wall of the reinforcing plate 113 is welded to the inner side wall 111 of the observation hole 112.

[0026] As Figures 2 to 4 shown, in order to further enhance the strength of the bottom side beam 11, a rib plate 115 adapted to its shape is fixed to the outer side wall of the bottom side beam 11. The rib plate 115 corresponds to the lock space 3, and an installation hole 1151 is opened inward on its outer plate surface corresponding to the observation hole 112. The installation hole 1151 communicates with the observation hole 112. In this embodiment, the installation hole 1151 extends downward to the top surface of the turn-lock plate 22, which can facilitate the installation of the reinforcing plate 113 and widen the reinforcing plate 113, so as to enhance the structure. Looking along the direction perpendicular to the outer side wall of the bottom side beam 11, the projected area of the installation hole 1151 is larger than the projected area of the observation hole 112 to facilitate the welding of the reinforcing plate 113 and the bottom side beam 11. The reinforcing plate 113 is C-shaped and its outer end extends outward from the installation hole 1151 to the outer side wall of the rib plate 115 to ensure the structural strength.

[0027] The container lock structure of the present utility model is provided with a connecting plate fixed between two bottom cross beams. The outer side of the connecting plate is fixedly connected to the inner side wall of the bottom side beam, and a rotary lock plate fixed to the bottom of the connecting plate and fixedly connected to the bottom side beam and the bottom cross beam is provided, so that the rotary lock plate, the bottom side beam, the two bottom cross beams and the connecting plate enclose a lock space for accommodating a twist lock and form a stable structure to improve the structural strength. A lock hole communicating with the lock space is opened upward on the bottom surface of the rotary lock plate, so that it is not necessary to directly open a lock hole on the bottom side beam, further improving the structural strength and achieving the purpose of extending the service life. The container lock structure of the present utility model has the characteristics of high strength and easy installation.

[0028] An embodiment of the present utility model further provides a container 100, including the container lock structure described in any one of the above embodiments.
