Description

Technical Field

[0001] This utility model relates to the field of container technology, and in particular to a hard-top detachable container. Background Technology

[0002] A hard-top detachable container is a special type of container whose top can be removed to facilitate loading and unloading of goods. This design allows it to be used as a standard dry cargo container or as an open-top container, suitable for transporting heavy, oversized, and oddly shaped cargo that needs to be loaded from the top.

[0003] Chinese patent CN221987216U discloses a hard-top detachable container, including a container body and a top cover corresponding to the container body. The container body and the top cover are connected by a limiting mechanism. The limiting mechanism includes a support plate, holes, insertion rods, fixing cylinders, locking blocks, locking slots, and springs. The support plate is fixed to the inner wall of the container body, and the support plate has holes inside. The bottom end of the top cover is fixed with an insertion rod corresponding to the holes, and the bottom end of the support plate is fixed with a fixing cylinder. Locking blocks are inserted into the left and right sides of the fixing cylinder. This hard-top detachable container allows it to slide along the outer wall of a vertical rod by a vertically movable sleeve. The movable sleeve can drive the hinge rod to rotate and push the locking blocks in and out of the locking slots, making it simpler to use, saving time and effort during operation, and improving the working efficiency of the equipment.

[0004] However, the above technical solution has the following shortcomings: When the insertion rod on the hardtop is inserted into the hole, since there are multiple limiting connection mechanisms and the hardtop is constantly being lifted by the hoisting equipment, multiple workers need to pull the movable sleeve down at the same time to make the lower surface of the top cover fit against the container before the hoisting equipment can release the top cover. In addition, the top cover is only fixed by multiple clips on both sides, which can easily cause the top cover to shake when the vehicle is running due to the gaps in the manufacturing of the parts and the elasticity of the spring itself, resulting in a large amount of noise. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a hard-top detachable container, which can not only reduce the difficulty of installing and disassembling the top cover, but also improve the stability of the connection between the top cover and the container body, thus ensuring the overall stability of the container.

[0006] The technical solution of this utility model is a hard-top detachable container, including a container body and a limiting connection mechanism; a top cover is provided on the top cover, and an installation plate is provided on the top cover. Two symmetrically distributed limiting frames and insert plates are respectively provided on the container body and the installation plate. The limiting frames are embedded in the groove formed by the insert plates and the container body; the number of limiting connection mechanisms is four and symmetrically distributed on the limiting frames, including a fixed frame provided on the limiting frame, a limiting rod slidably connected to the fixed frame, a convex ring coaxially provided on the limiting rod, and springs at both ends respectively provided on the convex ring and the fixed frame. One end of the limiting rod passes through the limiting frame and the insert plate and is inserted into the interior of the container body, and the other end of the limiting rod is provided with a grip ball.

[0007] Preferably, the insert plate is provided with an anti-slip pad, and the anti-slip pad and the limiting frame are in close contact with each other.

[0008] Preferably, the limiting rod is provided with an annular groove, and an elastic pad is provided inside the annular groove.

[0009] Preferably, the convex ring is provided with two horizontally distributed connecting rods, the connecting rods are provided with guide blocks, and the fixing frame is provided with a sliding groove for the guide blocks to slide horizontally.

[0010] Preferably, the limiting connection mechanism further includes a pin, which can pass through the fixing frame and the limiting rod.

[0011] Preferably, the mounting plate is provided with two symmetrically distributed side sealing plates, and the container body is provided with two support blocks, with the side sealing plates and support blocks fitting together.

[0012] Preferably, the support block and the container body are provided with linearly distributed second water guide channels.

[0013] Preferably, the top cover is provided with two lifting rings distributed front and back, and the top cover is provided with multiple inclined first water guide channels.

[0014] Compared with the prior art, the present invention has the following beneficial technical effects:

[0015] This utility model, through its insert plate, limiting frame, and limiting connection mechanism, enables the top cover to be quickly and securely installed on the container body. This eliminates the need for multiple workers to operate multiple connection mechanisms simultaneously during the fixing and snapping process, reducing the difficulty of installation and disassembly. Furthermore, the anti-slip pad increases the contact area between the mounting plate and the container body, improving the tightness of the connection surface. Simultaneously, the elastic pad fills the gap between the limiting rod and the slot, preventing the limiting rod from wobbling during insertion, further enhancing the stability of the top cover and demonstrating excellent practicality.

[0022] Example 1

[0023] like Figures 1-5 As shown in this embodiment, a rigid-top detachable container includes a container body 1 and a limiting connection mechanism. A top cover 2 is provided on the top of the container body 1, and a mounting plate 3 is provided on the top cover 2. Two symmetrically distributed limiting frames 4 and insert plates 5 are respectively provided on the container body 1 and the mounting plate 3. The limiting frames 4 are embedded in the groove formed by the insert plates 5 and the container body 1. The elongated insert plates 5 are inserted into the limiting frames 4, which not only fix the top cover 2 but also increase the contact area between the mounting plate 3 and the container body 1, improving the stability and tightness of the connection. Two symmetrically distributed side sealing plates 16 are provided on the mounting plate 3, and two support blocks 17 are provided on the container body 1. The side sealing plates 16 and support blocks 17 are mutually fitted. The side sealing plates 16 seal the sides of the connection between the mounting plate 3 and the container body 1, and simultaneously, in conjunction with the support blocks 17, pre-position the top cover 2 and the mounting plate 3.

[0024] like Figures 3-5 As shown, there are four limiting connection mechanisms symmetrically distributed on the limiting frame 4, including a fixed frame 7 set on the limiting frame 4, a limiting rod 8 slidably connected to the fixed frame 7, a convex ring 9 coaxially set on the limiting rod 8, and springs 10 set on the convex ring 9 and the fixed frame 7 respectively at both ends. One end of the limiting rod 8 passes through the limiting frame 4 and the insert plate 5 and is inserted into the interior of the container body 1. The other end of the limiting rod 8 is provided with a ball grip 15.

[0025] An anti-slip pad 6 is provided on the insert plate 5. The anti-slip pad 6 and the limit frame 4 are in close contact with each other. An annular groove is provided on the limit rod 8. An elastic pad 11 is provided inside the annular groove.

[0026] The limiting connection mechanism also includes a pin 21, which can pass through the fixing frame 7 and the limiting rod 8.

[0027] In this embodiment, after the insert plate 5 is inserted into the groove, multiple pins 21 are pulled out from the inside of the fixing frame 7. Under the action of the spring 10, the convex ring 9 drives the limiting rod 8 to slide, so that the limiting rod 8 passes through the limiting frame 4 and the insert plate 5 and is inserted into the circular groove on the container body 1, thus completing the fixed installation of the top cover 2. The elastic pad 11 fills the gap between the limiting rod 8 and the groove, preventing the limiting rod 8 from shaking during insertion. This eliminates the need for multiple workers to operate multiple connecting mechanisms simultaneously during fixed snap-fit, reducing the difficulty of installation and disassembly. Furthermore, the anti-slip pad 6 on the insert plate 5 can increase the friction between the insert plate 5 and the limiting frame 4, further improving the stability of the mounting plate 3, which has good practicality.

[0028] Example 2

[0029] like Figure 4 and Figure 5 As shown, this embodiment proposes a hard-top detachable container. Compared with the first embodiment, in this embodiment, the convex ring 9 is provided with two horizontally distributed connecting rods 12, and the connecting rods 12 are provided with guide blocks 13. The fixing frame 7 is provided with a sliding groove 14 for the guide blocks 13 to slide horizontally. The connecting rods 12 and the guide blocks 13 are provided to guide the rotation direction of the convex ring 9, which can ensure that the limiting rod 8 can be accurately inserted into the circular groove, and also ensure that the pin 21 can pass through the limiting rod 8 so that the limiting connection mechanism is in an unused state.

[0030] Example 3

[0031] like Figure 1 and Figure 2 As shown in the figure, this embodiment proposes a rigid-top detachable container. Compared with the first embodiment, in this embodiment, the support block 17 and the container body 1 are provided with linearly distributed second water guide channels 20, the top cover 2 is provided with two front and rear distributed lifting rings 18, and the top cover 2 is provided with multiple inclined first water guide channels 19. The lifting rings 18 are used for lifting equipment to fix the top cover 2 to realize the disassembly or installation of the top cover 2. The first water guide channels 19 and the second water guide channels 20 are used to guide the water on the top cover 2 and the container body 1 to prevent rainwater from accumulating on the surface of the container body 1 and the top cover 2.

[0032] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
