[0002] The locking rod device is also called a lock, door lock, etc. The good pressure resistance and stability of the locking rod device can be used in various fields such as automobiles, civil use, containers, etc. When the container is transported, the container door needs to be locked to achieve the need for the interior of the container to be in a sealed state, which is convenient for the subsequent long-distance transportation of items or goods stored in the container. In daily use, a double-headed locking rod device is needed to lock the container door.

[0003] When the existing double-headed locking rod device is in use, the dovetail lock head on the locking rod is usually connected to the lock frame on the container by bolts, thereby sealing the container. However, the existing connection method requires frequent installation and removal of bolts, which is more troublesome. In addition, when subjected to large internal or external forces, the lock head and the bolt are prone to bending or breaking, thereby affecting the normal use of the locking rod device and being difficult to meet usage requirements.

Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0021] Example 1

[0022] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a double-headed locking rod device, including a locking rod body 1, a fixing rod 2 is fixedly connected to the inner side of one end of the locking rod body 1, a U-shaped frame 3 is fixedly connected to the outer side of the fixing rod 2, a limiting slot 10 is penetrated through the top of the U-shaped frame 3, a movable rod 4 is arranged on the surface of the U-shaped frame 3, a spring 5 is sleeved on the outer side of the movable rod 4, one end of the movable rod 4 is connected to a limiting plate 6, a pull ring 7 is arranged on the top of the limiting plate 6, one end of the movable rod 4 movably penetrates the U-shaped frame 3 and is connected to a clamping block 8, a limiting frame 9 is arranged on the top of the clamping block 8, and the limiting frame 9 is clamped in the limiting slot 10.

[0023] The U-shaped frame 3 is provided with a card block 8 which is arranged in the U-shaped frame 3 and can limit the card block 8 in the up and down directions to prevent the spring 5 from repeatedly contracting and rebounding due to external vibration, thereby driving the card block 8 to jump. At the same time, the movable rod 4 rotates, prompting the limit frame 9 to be clamped in the limit clamping groove 10, and limiting the movable rod 4 to prevent the movable rod 4 from rotating due to internal or external force impact, thereby improving its stability. When the pull ring 7 is released, the spring 5 rebounds and pushes the limit plate 6 upward. At this time, under the influence of the rebound force of the spring 5, the card block 8 can effectively clamp the container lock frame, thereby completely locking the container door, thereby reducing the difficulty of manual operation and improving work efficiency. At the same time, the wear of the lock head is reduced, the damage stability is improved, the service life of the device is extended, and the actual use requirements are met.

[0024] Example 2

[0025] like Figure 1-Figure 4 As shown, an inner rod 11 is connected to the inner side of the end where the two locking rod bodies 1 are close to each other, and a mounting frame 12 is fixedly installed on the outer side of the inner rod 11, a fixing frame 13 is symmetrically arranged on the outer side where the two locking rod bodies 1 are close to each other, and a guide rod 14 is symmetrically arranged on the top and bottom of the mounting frame 12, one end of the guide rod 14 is movably passed through the fixing frame 13, a long-handled bolt 15 is arranged on the surface of the fixing frame 13, and one end of the long-handled bolt 15 is movably passed through the fixing frame 13, a bracket 16 is arranged on the outer side of the locking rod body 1, two stiffening ribs 17 are arranged on the outer side of the bracket 16, and mounting screw holes 18 are opened on both end sides of the bracket 16, two positioning rings 19 are arranged on the outer side of the locking rod body 1, and the bracket 16 is arranged on the end where the two positioning rings 19 are close to each other, a connecting frame 20 is arranged on the outer side of a single locking rod body 1, a rivet 21 is arranged on the surface of the connecting frame 20, and a handle 22 is arranged on the inner side of the connecting frame 20.

[0026] In this embodiment, by screwing a single long-handled bolt 15, or screwing two long-handled bolts 15 at the same time, the mounting frame 12 can be squeezed, so that the fixing frame 13 drives the corresponding locking rod body 1 to slide on the outside of the inner rod 11, and then the overall length of the locking rod body 1 is adjusted, thereby improving the flexibility and versatility of the device, and being able to adapt to containers of various sizes to meet different usage requirements. The bracket 16 can be limited by the positioning ring 19 to prevent the locking rod body 1 from shaking during use. The locking rod body 1 can be installed and fixed on the container door by using the bracket 16 to fit the outside of the locking rod body 1 and inserting the bolt into the mounting screw hole 18. The strength of the bracket 16 can be improved by the stiffening rib 17 to prevent the bracket 16 from bending and breaking, thereby improving the stability of the locking rod body 1 during use. The handle 22 can be fixed to the connecting frame 20 by the rivet 21. By grasping and toggling the handle 22 left and right, the locking rod body 1 can be driven to rotate, thereby realizing opening or closing the container door.

[0027] The working principle of this embodiment is as follows: when in use, first, according to the needs, screw a single or two long-handled bolts 15 to squeeze the mounting frame 12, so that the fixing frame 13 drives the corresponding long-handled bolt 15 to slide on the outside of the inner rod 11, and adjust the length of the lock rod body 1. Then, fit the two brackets 16 to the outside of the lock rod body 1, and insert the bolts into the mounting screw holes 18. Twist the bolts to install the lock rod body 1 on the container door, and then grasp and move the handle 22 left and right to rotate the lock rod body 1. Finally, when it is necessary to lock the container door, grasp and push and rotate the pull ring 7 at the same time to make the block 8 fit the bottom of the container lock frame, and at the same time make the limit frame 9 snap into the limit slot 10, and then release the pull ring 7 to make the spring 5 rebound. Under the influence of the rebound force of the spring 5, the block 8 will clamp the lock frame, thereby locking and sealing the container, thereby completing the use of the double-headed lock rod device.
