Description

Technical Field

[0001] This utility model relates to the field of container technology, and in particular to a rotating lock mechanism for a container door panel. Background Technology

[0002] Currently, common container doors use internal latches for closure, allowing only opening and closing from inside the container, resulting in a simple operating mechanism. Similarly, the industry typically uses pre-made cold storage locks, which are costly and lack sufficient strength. Furthermore, conventional lock structures are unsuitable for container installation, being more appropriate for residential use. Therefore, it is necessary to develop a container door flap rotary lock mechanism suitable for containers. A search revealed no identical technical solutions to this invention. Utility Model Content

[0006] A lock base, the lock base including a second mounting plate fixedly mounted on a container door and a fixing plate mounted on the second mounting plate;

[0007] The rotary lock body can be locked in place with the lock seat.

[0008] In some embodiments, a hinge is provided between the first mounting plate and the lock box, the hinge including plate A and plate B, plate A being fixed to the first mounting plate and the lock box being fixed to plate B.

[0009] In some embodiments, the lock box includes a housing, a lock cylinder, and a rotating plate. The lock cylinder is assembled inside the housing and a guide tube is fitted onto the lock cylinder. The rotating plate is also fitted onto the lock cylinder, and the guide tube is sandwiched between the inner wall of the housing and the rotating plate.

[0010] In some embodiments, the end of the lock cylinder is further provided with a locking assembly for fixing the rotating plate, the locking assembly consisting of a washer, a spring washer and a nut.

[0011] In some embodiments, the fixing plate includes an A side and a B side, the A side being fixed to the second mounting plate, and the upper edge of the B side having a locking groove for the rotating plate to be inserted.

[0012] In some embodiments, the fixing plate is secured to the second mounting plate by fasteners, such as bolts and nuts.

[0013] The beneficial effects of this utility model are: This technical solution increases security by adding a rotary lock mechanism to the external lock to lock the box door and small door. The lock body has high strength and strong corrosion resistance and can act as a door stop when locked. Attached Figure Description

[0017] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] like Figure 1 and Figure 2 As shown, this utility model embodiment provides a container door baffle rotary lock mechanism, which is used to lock the small door and the container door from the outside. It includes a rotary lock body 100 and a lock seat 200, and the rotary lock body 100 can cooperate with the lock seat 200 to lock.

[0019] The rotary lock body 100 includes a first mounting plate 101 fixedly mounted on the outer edge of the small door and a lock box mounted on the first mounting plate 101. The lock box can be freely opened and closed on the first mounting plate 101. A hinge 102 is provided between the first mounting plate 101 and the lock box. The hinge 102 includes plate A and plate B. Plate A is fixed on the first mounting plate 101, and the lock box is fixed on plate B.

[0020] The lock box includes a housing 111, a lock cylinder 112, and a rotating plate 114. The lock cylinder 112 is assembled inside the housing 111, and a guide tube 113 is fitted onto the lock cylinder 112. The rotating plate 114 is also fitted onto the lock cylinder 112, with the guide tube 113 sandwiched between the inner wall of the housing 111 and the rotating plate 114. The end of the lock cylinder 112 is also provided with a locking assembly for fixing the rotating plate 114, which consists of a washer, a spring washer, and a nut. The housing 111 is made of SPA-H sheet metal commonly used in shipping containers, which is bent to protect the lock cylinder 112 from impact damage.

[0021] The lock base 200 includes a second mounting plate 201 fixedly mounted on the container door and a fixing plate 202 mounted on the second mounting plate 201. The fixing plate 202 is fixed to the second mounting plate 201 by fasteners 115, which are bolts and nuts. The fixing plate 202 includes a side A and a side B, wherein side A is fixed to the second mounting plate 201, and the upper edge of side B is provided with a locking groove for the rotating plate 114 to be inserted.

[0022] The structure of this technical solution is made entirely of carbon steel and hot-dip galvanized to enhance its corrosion resistance. Based on the above structure, the working principle of this technical solution is as follows: rotating the lock cylinder 112 drives the rotating plate 114 assembled on the lock cylinder 112 to rotate. The guide tube 113 can control the rotation angle of the rotating plate 114 to be stable and prevent the rotating plate 114 from deviating significantly within the rotation plane. The rotation of the rotating plate 114 achieves the locking effect by engaging with the lock groove on the fixing plate 202 of the lock seat 200.

[0023] In summary, this technical solution increases security by adding an external rotary lock mechanism to lock the container door and side doors. The lock body is strong, corrosion-resistant, and can act as a door stop when locked. Furthermore, the components are manufactured in-house, allowing for flexible design of the lock body size to suit different containers.

[0024] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
