[0012] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments. However, the specific implementation methods and embodiments described below are only for illustrative purposes and are not intended to limit the present invention.

[0013] In the description of the present invention, it should be understood that the terms "longitudinal", "transverse", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate directions or positional relationships based on the attached text. Figure 1 The directions or positional relationships shown are only for the convenience of describing the present invention, and do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, they should not be understood as limiting the present invention.

[0014] In the description of this application, the terms "first", "second", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.

[0015] In order to solve the above technical problems, Figure 1-2As shown, the utility model designs a kind of easy-to-open lock for container, comprises a first lock head 1, a second lock head 2, a first limiting seat 3, a locking rod 4, a handle seat 5, and a handle 6. The two first limiting seats 3 are arranged opposite to each other up and down, the first limiting seat 3 is fixed on the door panel, the locking rod 4 passes through the inner side of the first limiting seat 3, the first limiting seat 3 can limit the locking rod 4 inside without affecting its free rotation, the upper end of the locking rod 4 is fixedly connected to the first lock head 1, the lower end of the locking rod 4 is fixedly connected to the second lock head 2, the handle seat 5 is fixedly connected to the locking rod 4, a positioning pin shaft 7 is provided in the socket of the handle seat 5, the handle 6 is rotatably matched with the positioning pin shaft 7 in the handle seat 5, the handle 6 can rotate around the positioning pin shaft 7 and match with the door panel handle lock seat, this The design allows the operator to lock and unlock more easily, reducing operation time and labor intensity. V-shaped limit grooves are provided on the left and right sides of the first lock head 1. After cooperating with the lock seat on the door panel, in the locked state, the V-shaped grooves on both sides are limited, providing a stable locking effect. This design not only enhances the security of the container door, but also improves the durability and reliability of the lock, ensuring the safety of the container during transportation. The second lock head 2 is in the shape of a hook. The single hook design has a certain limiting effect and makes it more convenient to open the container door. This design reduces the operating steps when opening, improves the opening efficiency of the door panel, and thus speeds up the loading and unloading speed of the container. This is an important advantage for the logistics industry that requires fast loading and unloading of goods.

[0016] In this embodiment, it is further preferred that the second lock head 2 has an arc-shaped bayonet 8. The design of the arc-shaped bayonet 8 makes the engagement between the lock head and the lock seat tighter. The shape of the arc-shaped bayonet 8 reduces the friction between the lock head and the lock seat, reduces the degree of wear, and thus prolongs the service life of the lock. In addition, the arc-shaped bayonet 8 can better withstand external pressure and impact, maintain its structural integrity, and the design of the arc-shaped bayonet 8 makes the lock smoother when opening and more convenient to operate. The user only needs to pull or push lightly to achieve quick unlocking, which greatly improves the loading and unloading efficiency of the container, especially in occasions where frequent opening is required, which can significantly save time and labor costs.

[0017] It is further preferred in this embodiment that a second limit seat 9 is also included, and the second limit seat 9 is located between the two first limit seats 3 on the upper and lower sides. The cross-sections of the first limit seat 3 and the second limit seat 9 are both U-shaped, and the length of the second limit seat 9 is less than the length of the first limit seat 3, which enhances the stability of the overall locking rod 4 assembly structure. The first limit seat 3 and the second limit seat 9 are both installed on the door panel by bolts, which ensures the stability of the installation while simplifying the installation process and improving the installation efficiency.

[0018] It is further preferred in this embodiment that a bushing 10 is provided on the inner side of the first limit seat 3 and the second limit seat 9, which reduces wear and tear, extends the service life of the lock, provides a smoother operating experience, reduces the operating resistance caused by friction, and makes the opening and locking of the lock easier.

[0019] Based on the above embodiment, further improvements are made in that the outer peripheral surface of the locking rod 4 is provided with axial reinforcement ribs, and a number of the axial reinforcement ribs are evenly spaced around the circumference of the locking rod 4, thereby enhancing the structural strength of the locking rod 4, making it more able to withstand external pressure and impact, reducing the possibility of deformation, and improving the durability of the locking rod 4. Especially when subjected to long-term heavy loads or frequent operations, the stability and reliability of the locking rod 4 are significantly improved.

[0020] It is worth noting that the technical features such as the lock seat, bolt connection, welding, etc. involved in this utility model patent application should be regarded as prior art. The specific structure, working principle, and possible control method and spatial layout method of these technical features can be selected by conventional options in the field, and should not be regarded as the inventive point of this utility model patent. This utility model patent will not be further elaborated.

[0021] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made by technicians in the relevant technical field based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
