Description

Technical Field

[0001] This utility model belongs to the field of container technology, specifically, it relates to a top plate tensioning device for a hard-top container and a hard-top container. Background Technology

[0002] In container shipping, due to cargo size or loading / unloading efficiency, some goods are loaded and unloaded from the top of the container. Hardtop containers are designed to meet this need, allowing for loading from either the door or the top. These containers are typically designed with a removable top panel, secured to the main container body via locking rods.

[0003] like Figure 1 , Figure 2 As shown, the current mainstream top cover locking rod design fixes the top plate to the bottom box by tightening the locking rods on both sides. Considering sealing and other issues, a sealing strip is usually installed inside the top cover. Therefore, during the tightening process, the top cover locking rod is first pulled down and then kept locked. As a result, the locking rod will not only be subjected to an upward force during use, but also a flipping force. This flipping force will cause the top of the locking rod to deform during use, resulting in problems such as difficult assembly or disengagement.

[0004] Therefore, developing a top plate tensioning device for rigid top containers and a rigid top container, so that the top rod will not be subjected to torsional force during the use of the rigid top container, and reducing the deformation and damage of the locking rod under long-term use, is an urgent technical problem to be solved. Utility Model Content

[0005] The purpose of this utility model is to provide a top plate tensioning device for a hard-top container and a hard-top container. During the use of the hard-top container, the top rod will not be subjected to torsional force, reducing the deformation and damage of the locking rod under long-term use.

[0006] To achieve the above-mentioned objectives, the present invention employs the following technical solution: In one aspect, this utility model proposes a top plate tensioning device for a rigid-opening box, comprising: A locking rod support is used to connect to the top plate side beam assembly. A limiting groove is formed on the upper surface of the locking rod support. A first through passage extends vertically from the locking rod support and passes through the limiting groove. A locking rod assembly includes a lock head and a locking rod, wherein the lock head is connected to the upper end of the locking rod; the locking rod can drive the lock head through the first through passage, and when the locking rod can drive the lock head through the first through passage to move above the limiting groove, the locking rod can drive the lock head to rotate and move down until the lock head is locked in the limiting groove; The handle is connected to the lower end of the locking rod. The handle can be flipped to move the locking rod up or down. The handle and the locking rod can rotate relative to each other.

[0007] In some embodiments of this application, the locking bar support includes two locking bar support seats, and the first through passage is formed between the two locking bar support seats.

[0008] In some embodiments of this application, the lock head is a cylindrical structure; When the cylindrical structure extends along the first through passage formed on the two locking rod support seats, the cylindrical structure can move through the first through passage; when the cylindrical structure moves along the first through passage to above the locking rod support, the cylindrical structure rotates to above the two locking rod support seats, and the locking rod drives the locking head to move down until the locking head is locked in the limiting groove.

[0009] In some embodiments of this application, an arc-shaped groove is formed on the locking rod support portion, and two of the arc-shaped grooves form the limiting groove.

[0010] In some embodiments of this application, the locking rod support has a first inclined portion and a second inclined portion, the first inclined portion and the second inclined portion are inclined in opposite directions, and the arc-shaped groove is formed at the connection between the first inclined portion and the second inclined portion.

[0011] In some embodiments of this application, the cylindrical structure is a circular structure.

[0012] On the other hand, this application also relates to a rigid open-top container, comprising: Several of the above-mentioned rigid-top box top plate tensioning devices; A top plate side beam assembly, wherein several of the aforementioned locking rod support portions are spaced apart and connected to the top plate side beam assembly; The side panel top beam assembly has a second through passage formed along the vertical direction; The locking rod passes through the second through passage and the first through passage in sequence; The side plate top beam assembly is sealed to the top plate side beam assembly.

[0013] In some embodiments of this application, the side plate top beam assembly includes a first side plate top beam and a second side plate top beam, wherein the lower end of the first side plate top beam is connected to the upper end of the second side plate top beam; The top plate side beam assembly includes a top plate side beam body and a sealing component, wherein the sealing component is embedded in the top plate side beam body; The upper end of the top beam of the first side plate is pressed against the sealing component.

[0014] In some embodiments of this application, a side plate is also included, on which the handle is foldably attached.

[0015] In some embodiments of this application, the locking rod extends vertically and is disposed on the outer side of the side plate.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are: By connecting a locking rod support to the top plate side beam assembly, a limiting groove is formed on the upper surface of the locking rod support. A first through-passage extends vertically along the locking rod support, penetrating the limiting groove. The upper end of the locking rod can drive the lock head through the first through-passage and extend above the limiting groove. Rotating the locking rod relative to the handle until the lock head can be engaged in the limiting groove, the locking rod drives the lock head downwards and engages in the limiting groove, thus achieving the engagement between the locking rod support and the locking rod assembly. Since the lock head is directly connected to the top of the locking rod, the weight of the locking rod... By directly applying force to the limiting groove with the lock head, the weight of the lock rod assembly and the handle is directly applied vertically to the lock rod support. With the lock head engaged in the limiting groove, the top beam of the first side plate presses against the sealing component, causing the top plate side beam to experience an upward thrust. Since the lock rod support is connected to the top plate side beam, and the lock head is engaged in the limiting groove on the upper surface of the lock rod support, the upward thrust acting on the top plate beam is applied to the top plate side beam, the lock rod support, and the lock rod assembly, preventing the formation of... Figure 1 The existing lock head is subjected to the torsional force indicated by the arrow, thereby reducing the stress deformation of the top plate tensioning device for hard-opening top boxes and reducing the risk of damage to the top plate tensioning device for hard-opening top boxes.

[0026] In some embodiments of this application, such as Figure 3 , Figure 5 , Figure 6 As shown, a rigid open-top container is disclosed, including a top plate tensioning device, a top plate 400, and side plates 500. The top plate 400 is detachably connected to the side plates 500 via the top plate tensioning device. The top plate tensioning device can press the top plate 400 tightly against the side plates 500, achieving a sealed connection between the top plate 400 and the side plates 500.

[0027] In other embodiments of this application, such as Figure 4 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 As shown, this application relates to a top plate tensioning device for a hard-opening roof box, which includes a locking rod support 100, a locking rod assembly 200, and a handle 300.

[0028] The top slab 400 includes the top slab side beam assembly 410.

[0029] The locking bar support 100 is connected to the top plate side beam assembly 410. The locking bar support 100 extends from the top plate side beam assembly 410 toward the outer side of the side plate 500 of the hard-top container.

[0030] A limiting groove is formed on the upper surface of the locking rod support 100.

[0031] A first through passage 120 is formed on the upper part of the locking bar support 100 along the vertical direction.

[0032] The first through passage 120 penetrates the limiting groove.

[0033] The locking rod assembly 200 includes a locking head 210 and a locking rod 220. The locking head 210 is connected to the upper end of the locking rod 220. The upper end of the locking rod 220, to which the locking head 210 is connected, can pass through the first through passage 120 to the top of the limiting groove. The locking rod 220 can also drive the locking head 210 to rotate to a direction where it can engage with the limiting groove, and then the locking rod 220 drives the locking head 210 to move downward until the locking head 210 engages with the limiting groove.

[0034] A handle 300 is provided to enable the movement and rotation of the locking lever 220. The lower end of the locking lever 220 is connected to the handle 300, and the handle 300 can be flipped to move the locking lever 220 up or down.

[0035] The locking lever 220 can rotate relative to the handle 300, thereby enabling the locking lever 220 to drive the lock head 210 to rotate. When the lock head 210 is engaged in the limiting groove, the locking lever 220 can drive the lock head 210 to rise. Then, the locking lever 220 rotates relative to the handle 300, driving the lock head 210 to rotate, until the lock head 210 can move along the first through passage 120.

[0036] One end of the handle 300 is rotatably connected to the side plate 500, thereby enabling the handle 300 to be flipped relative to the side plate 500.

[0037] The locking rod 220 extends vertically and is located on the outer side of the side plate 500.

[0038] The handle 300 is flipped upwards, pulling the locking rod 220 upwards. The locking rod 220 drives the locking head 210 to move out of the limiting groove and move above the limiting groove, releasing the locking head 210 from the limiting groove.

[0039] The handle 300 is flipped downwards, pulling the locking rod 220 downwards. The locking rod 220 drives the locking head 210 to descend and move into the limiting groove, thus achieving the engagement of the locking head 210 with the limiting groove. This is the tightened state of the top plate tensioning device for hard-opening top boxes.

[0040] With the lock head 210 disengaged from the limiting groove, the lock rod 220 rotates relative to the handle 300 until the lock head 210 can move along the first through passage 120. In this state, the lock rod assembly 200 can be disengaged from the lock rod support 100, thereby separating the top plate 400 from the side plate 500. This is the state where the top plate tensioning device for the hard-open top box is released from tension.

[0041] The locking bar support 100 includes two locking bar support seats 130. A first through passage 120 is formed between the two locking bar support seats 130.

[0042] An arc-shaped groove 111 is formed on the locking rod support 130. Two arc-shaped grooves 111 form a limiting groove.

[0043] A first inclined portion 131 and a second inclined portion 132 are formed on the locking bar support 130. The first inclined portion 131 and the second inclined portion 132 are inclined in opposite directions, and an arc-shaped groove 111 is formed at the connection between the first inclined portion 131 and the second inclined portion 132.

[0044] The lock head 210 has a cylindrical structure.

[0045] With the cylindrical structure extending along the first through passage 120 formed on the two locking rod support seats 130, the cylindrical structure can move through the first through passage 120; with the cylindrical structure moving along the first through passage 120 to above the locking rod support 100, the cylindrical structure rotates to above the two locking rod support seats 130, and the locking rod 220 drives the locking head 210 to move down until the locking head 210 is locked in the limiting groove.

[0046] Specifically, the columnar structure can be a cylindrical structure.

[0047] In some embodiments of this application, the side panel 500 includes a side panel top beam assembly 510. A second through passage 511 is formed in the vertical direction on the side panel top beam assembly 510, and the locking rod 220 passes through the second through passage 511 and the first through passage 120 in sequence.

[0048] The first through passage 120 and the second through passage 511 serve to guide the movement of the locking bar 220. Both the first through passage 120 and the second through passage 511 are vertically oriented, allowing the locking bar 220 to move vertically along both passages. Furthermore, while moving vertically within the first through passage 120 and the second through passage 511, the locking bar 220 can also move horizontally.

[0049] With the lock head 210 locked in the limiting groove, the side plate top beam assembly 510 and the top plate side beam assembly 410 are sealed together, thereby achieving a sealed connection between the top plate 400 and the side plate 500.

[0050] The side panel top beam assembly 510 includes a first side panel top beam 512 and a second side panel top beam 513. The lower end of the first side panel top beam 512 is connected to the upper end of the second side panel top beam 513.

[0051] The top plate side beam assembly 410 includes a top plate side beam body 411 and a sealing component 412, with the sealing component 412 embedded in the top plate side beam body 411; The upper end of the top beam 512 of the first side plate is pressed against the sealing component 412.

[0052] In the description of the above embodiments, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0053] Whenever possible, the various aspects and features described and shown in the specification can be applied individually, and these individual aspects can serve as the subject of a divisional application.

[0054] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
