AI Technical Summary
The existing container lifting locking bar cannot be linked with the rear door during the lifting process, which affects the normal use of the locking device.
A container lifting locking bar was designed, including a lock head, a locking bar and a door handle. Through the axial sliding cooperation between the anti-rotation sliding bar and the locking bar, the locking bar is ensured not to rotate during the lifting process, so as to achieve the normal locking function with the lock seat.
It achieves normal linkage between the container lifting lock bar and the lock seat during the lifting process, ensuring the stability and security of the lock function.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to a container lifting lock rod belongs to the technical field of container accessories. BACKGROUND
[0002] With the improvement of logistics demand, containers are widely used. The applicant is a container manufacturing and research and development enterprise. In the manufacturing process, the research and development personnel found that the tail of the carriage can be lowered to effectively reduce the wind resistance and save fuel. However, in order to ensure that the tail of the carriage can be lowered at the same time as the rear door of the vehicle is lowered, the normal locking function of the rear of the carriage must be ensured in the lifting state, so it is urgent to develop a lock rod structure matched with the rear of the lifting. SUMMARY
[0003] The technical problem to be solved by the utility model is to provide a container lifting lock rod which can be linked with the rear of the lifting and does not affect the function of the lock that rotates to drive the lock head to cooperate with the lock seat.
[0004] To solve the above problems, the specific technical scheme of the utility model is as follows: a container lifting lock rod, comprising a lock head, a lock rod and a door handle, the lock rod is composed of an upper lock rod and a lower lock rod, the top of the upper lock rod is connected with an upper lock head, and the lower end of the lower lock rod is connected with a lower lock head; the door handle is positioned and connected with the lower lock rod; a rotation prevention sliding rod is arranged between the upper lock rod and the lower lock rod, the rotation prevention sliding rod is axially slidably connected with the upper lock rod and / or the lower lock rod, and there is no relative rotation in the radial direction.
[0005] The rotation prevention sliding rod is a square shaft, square holes are arranged in the upper lock rod and / or the lower lock rod which slide in cooperation, and the square shaft is axially slidably connected with the square holes.
[0006] The rotation prevention sliding rod is a cylindrical shaft, cylindrical holes are arranged in the upper lock rod and / or the lower lock rod which slide in cooperation, and the cylindrical shaft is axially slidably connected with the cylindrical holes; a limiting protrusion is arranged on the circumferential surface of the rotation prevention sliding rod, and a sliding groove is arranged on the upper lock rod and / or the lower lock rod, and the limiting protrusion is slidably connected with the sliding groove at the corresponding position.
[0007] The limiting protrusion is a square key or a round pin shaft.
[0008] The container lifting lock rod of the application adopts the above structure, realizes the purpose of limiting the rotation prevention sliding rod to slide along the axis of the upper lock rod or the lower lock rod and rotate together, and ensures that the lifting lock rod can only stretch and contract along a specific direction and rotate in linkage with the upper and lower connecting rods, so that the operation is simple, safe and reliable.

[0018] As shown in the figure, a container lifting lock lever comprises a lock head, a lock lever and a door handle 3, the lock lever is composed of an upper lock lever 1 and a lower lock lever 2, the top of the upper lock lever 1 is connected with an upper lock head 4, the lower end of the lower lock lever 2 is connected with a lower lock head 5; the door handle 3 is positioned and connected with the lower lock lever 2; a rotation prevention slide lever 6 is arranged between the upper lock lever 1 and the lower lock lever 2, the rotation prevention slide lever 6 is a square shaft, the lower end of which is welded or integrally structured with the top of the lower lock lever 2; the lower end of the upper lock lever 1 is provided with a square hole, the square shaft and the square hole are axially slidably matched, since the shaft is square in structure, when the door handle 3 below rotates, the lower lock lever 2 rotates together with the upper lock lever 1, realizing the locking function of the lock head and the lock seat. Figures 1 to 3 Embodiment two As shown in the figure, the rotation prevention slide lever 6 is a cylindrical shaft structure, the lower end of which is welded or integrally structured with the top of the lower lock lever 2; a limiting protrusion 7 is arranged on the outer circumference of the rotation prevention slide lever 6, the limiting protrusion 7 is a square key structure, the square key is slidably matched with the slide groove arranged on the upper lock lever 1, thereby realizing the relative sliding between the upper lock lever 1 and the lower lock lever 2, and the common rotation. The rest of the structure is the same as that of embodiment one.
[0019] Embodiment three Figures 4 to 6 As shown in the figure, except that the limiting protrusion 7 is a round pin shaft structure, the rest is the same as that of embodiment two.
[0020] As shown in the figure, except that the limiting protrusion 7 is a round pin shaft structure, the rest is the same as that of embodiment two. Figures 7 to 9
[0021] In addition to the above embodiments, the anti-rotation slide rod 6 of the present application can also be replaced by a sleeve shaft structure.
