Description

Technical Field

[0001] This invention belongs to the technical field of container securing, and in particular relates to an extension rod for securing containers. Background Technology

[0002] When lashing multi-layer containers, the connection between the container and the deck (as well as the hatch cover and lashing bridge) is usually secured by a combination of tie rods, turnbuckles and eye plates. Because the distance between the lashing points is different, and some distances vary greatly, the lengths of the tie rods and turnbuckles used may be different, requiring multiple different models to meet the requirements. This greatly increases production costs and management difficulty. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide an extension rod for container securing, which serves as a distance compensation for tie rod connections in container securing, reduces the number of tie rod and turnbuckle product models used, and lowers costs and management difficulty.

[0004] The technical solution adopted by this invention to solve its technical problem is to provide a container securing extension rod, including a multi-section rod, a clamp, a shaft, a limiting pin, and a spring. The clamp is generally clamp-shaped, including a connecting head and upper and lower symmetrical clamping arms. The end of the multi-section rod is connected to the connecting head of the clamp. The middle of the upper and lower clamping arms is correspondingly provided with shaft holes. The upper and lower clamping arms are respectively provided with limiting pin grooves offset circumferentially along the shaft holes. The limiting pin grooves are opened downward along the top of the two clamping arms and communicate laterally with the shaft holes. The inner rear part of the upper and lower clamping arms is correspondingly provided with a rod clamping groove. The limiting pin is laterally fixed to the top of the shaft. The spring is sleeved at the bottom of the limiting pin. The shaft is set in the shaft hole of the clamp. During the connection process, the limiting pin is first located in the limiting pin groove of the lower clamping arm, and as the shaft compresses the spring, it is lifted upward and rotated to be engaged in the limiting pin groove of the upper clamping arm.

[0005] The end of the multi-section rod is provided with an external thread, and the connecting head of the chuck is provided with a connecting hole. The connecting hole is provided with an internal thread, and the end of the multi-section rod is connected to the connecting head of the chuck by a thread.

[0006] The limiting pin grooves of the upper and lower clamping arms are offset by 180° along the circumference of the shaft hole.

[0007] A handle is provided at the bottom end of the shaft.

[0008] The cross-section of the clamping groove of the tie rod section is an arc shape that matches the outer ring surface of the tie rod section.

[0009] The space between the upper and lower clamping arms is a hollow structure.

[0010] Beneficial effects

[0011] This invention achieves a connection with the head joint of the tie rod, and then connects it to the turnbuckle via a multi-section rod, thereby solving the distance compensation problem of tie rod connection in existing container securing systems. When the distance between the lashing points is different, the same type of tie rod and turnbuckle can still be used. Distance compensation is achieved by extending the rod, which greatly reduces the number of product models, lowers product costs, and reduces management difficulty and costs.

[0017] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0018] like Figure 1-5 The container securing extension rod shown includes a multi-section rod 1, a clamp 2, a shaft 3, a limiting pin 4, and a spring 5.

[0019] The multi-section rod 1 consists of two sections. The clamp 2 is shaped like a clip, including a connecting head and symmetrical upper and lower clamping arms, with a cavity structure between the two arms. The end of the multi-section rod 1 connects to the connecting head of the clamp 2. The end of the multi-section rod 1 has external threads, and the connecting head of the clamp 2 has a connecting hole with internal threads. The end of the multi-section rod 1 and the connecting head of the clamp 2 are connected by threads.

[0020] The upper and lower clamping arms have corresponding shaft holes 6 in their middle sections. Each of the upper and lower clamping arms has a 180° offset locating pin groove 7 along the circumference of the shaft hole 6. The locating pin groove 7 extends downwards along the top of the two clamping arms and communicates laterally with the shaft hole 6. Correspondingly, the inner rear sides of the upper and lower clamping arms have corresponding pull rod clamping grooves 8, the cross-section of which is an arc shape matching the outer ring surface of the pull rod. The locating pin 4 is laterally fixed to the top of the shaft 3, and the spring 5 is fitted onto the bottom of the locating pin 4. A handle 9 is located at the bottom of the shaft 3. The shaft 3 is positioned in the shaft hole 6 of the clamping head 2. During connection, the locating pin 4 is initially located in the locating pin groove 7 of the lower clamping arm. As the shaft 3 compresses the spring 5, it rises and rotates, locking into the locating pin groove 7 of the upper clamping arm.

[0021] The operating steps for using the container-mounted extension rod are as follows:

[0022] (1) Pull the shaft 3 to the bottom of the clamp head 2 and place the limiting pin 4 in the limiting pin groove 7 of the lower clamp arm;

[0023] (2) Insert the last joint of the pull rod into the clip 2;

[0024] (3) The lifting shaft 3 inserts the limiting pin 4 into the upper shaft hole 6 of the clamp head 2 and rotates 180° to clamp into the limiting pin groove 7 of the upper clamping arm. At the same time, the joint of the pull rod enters the clamping groove 8 of the pull rod section. The return tension of the spring 5 makes the upper and lower clamping arms clamp each other, so that the extension rod and the pull rod are firmly connected and the extension rod will not fall off the pull rod.

[0025] (4) Insert the joint of the extension rod into the turnbuckle, tighten the turnbuckle, and complete the binding and securing.
