Description

Technical Field

[0001] The utility model relates to the technical field of container production, and more specifically, to a hard-open top locking device. Background Art

[0002] Hard-top containers are containers that have a strong, detachable hard-top cover, because the canvas cover of an open-top container is not waterproof. The lintel of a hard-top container is the same as that of an open-top container and can be rolled out or removed, but it cannot carry super-high cargo and is generally used to carry precision machinery cargo.

[0003] The mainstream hard-top containers on the market are of a relatively high height and are equipped with a locking device that can be operated on the ground. The locking rod handle is installed at the lower end of the box body. When the locking rod handle of the locking device is turned, the axis of the locking rod will be displaced axially relative to the locking state. Therefore, the opening diameter of the top side beam needs to be larger than the locking rod diameter, so that reinforcement and restraint cannot be performed between the locking rod and the side panel. If an external force hits the end of the locking rod during transportation, the axis of the locking rod may rotate or displace until it leaves the top cover, resulting in poor anti-theft effect. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a hard-open top locking device to solve one or more of the above-mentioned problems.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

DETAILED DESCRIPTION

[0019] Example:

[0020] The following is combined with Figure 1-3 The utility model is described in further detail.

[0021] A hard open top locking device, such as Figure 1 As shown, the main body is a locking rod 10 composed of a two-section rod tube 12. The two sections of the rod tube 12 are connected by an adjusting bolt group 11. The adjusting bolt group 11 is divided into upper and lower threaded rods, which are inserted into the threaded grooves at the butt ends of the two sections of the rod tube 12. The overall component can adjust the relative distance between the two sections of the rod tube 12 and fine-tune the length of the locking rod 10. The bolt fixing adjustment part of the component is used to ensure that the top end of the locking rod 10 is buckled on the top side beam.

[0022] A pressing unit 20 is provided on the top of the locking rod 10, and the pressing unit 20 includes a hard top plate pressing block 21 and a pressing block connecting shaft 22. The right end of the hard top plate pressing block 21 is connected to the top of the locking rod 10 through the pressing block connecting shaft 22, and the left end of the hard top plate pressing block 21 is a downward-folded hook head structure, which is convenient for subsequent pressing and buckling to improve stability.

[0023] The bottom of the lock rod 10 is riveted to the rotating handle 40 through an adjusting screw. The bottom of the lock rod 10 is riveted to the right of the rotating handle 40 but not the right end. The right end of the rotating handle 40 needs to be riveted to the container side panel through a fixing unit 50. Figure 2 As shown, the adjusting connecting rod 30 includes two integrally formed riveted joints 31 and an adjusting connecting shaft 32. The corresponding riveted joints 31 are arranged at both ends of the adjusting connecting shaft 32. The riveted joint 31 at the upper end is riveted to the bottom of the locking rod 10, and the riveted joint 31 at the lower end is riveted to the rotating handle 40. The fixing unit 50 includes a handle seat 51 with a pin, a fixing sleeve 52 and a matching fixing nut 53. The fixing sleeve 52 is fixed to the side plate of the container. The handle seat 51 has a pin at the bottom, and the top of the handle seat 51 is riveted to the right end of the rotating handle 40. The pinned end of the handle base is inserted into the fixing sleeve 52 and locked by the thread and fixing nut 53 at the bottom.

[0024] The left end of the rotating handle 40 is restricted and fixed by the limit unit 60. The limit unit 60 includes an upper limit unit, a lower limit unit, and a handle plate 61. The upper limit unit includes an upper limit block 62 and a plate upper head 63, and the lower limit unit includes a lower limit block 64 and a plate lower head 65. From top to bottom, they are the plate head 63, the upper limit block 62, the lower limit block 64, and the plate lower head 65. Among them, the upper limit block 62, the lower limit block 64, and the plate lower head 65 are fixed on the container side plate. The bottom end of the handle plate 61 is riveted to the plate lower head 65, and the spacing between the plate upper head 63 and the plate lower head 65 is to ensure that when the handle plate 61 is rotated to the vertical upward position, the top of the handle plate 61 is not affected by the upper limit block 62. The upper right end of the upper limit block 62 is notched so that the handle 40 can be stuck in this notch position after being rotated counterclockwise. The positions and spacing between the upper limit block 62 and the lower limit block 64 are such as to ensure that the handle 40 is stuck between the upper limit block 62 and the lower limit block 64 when the handle 40 is turned horizontally.

[0025] A component such as a bracket 66 may also be installed on the locking rod 10 to strengthen the fixation.

[0026] In the locked state, Figure 1 As shown, the rotating handle 40 is horizontally stuck between the upper limit block 62 and the lower limit block 64, and is restricted from slipping outward by the handle pressing plate 61 arranged vertically upward, and the handle pressing plate 61 is fixed by the head 63 on the top pressing plate. Figure 3 As shown, when the container side door needs to be opened, the handle pressure plate 61 is removed or pulled outward to release the restriction on the rotating handle 40, and the rotating handle 40 is rotated counterclockwise. At this time, due to the design of multiple fixed points and riveted points, an additional adjustment link 30 is added for buffering. The displacement of the original axis lateral movement is converted into the riveted rotation momentum between the adjustment link 30, the rotating handle 40 and the locking rod 10. The locking rod 10 realizes vertical movement without left and right deviation. This makes it convenient to set up additional brackets 66 and other components to reinforce the locking rod 10, and can also reduce the opening size of the top side beam without affecting the opening and closing of the door. The movement of the locking rod 10 causes the top hard top plate pressure block 21 to loosen relative to the top side beam. At this time, the door can be opened normally. Similarly, the reverse operation can re-lock the door.

[0027] It should be noted that this specific embodiment is merely an explanation of the present utility model, and it is not a limitation of the present utility model. After reading this specification, those skilled in the art can make non-creative modifications to the present embodiment as needed, but as long as it is within the scope of the claims of the present utility model, it is protected by the patent law.
