Description

Technical Field

[0001] This utility model belongs to the field of container technology, specifically relating to a quick-release container. Background Technology

[0002] With the rapid development of the social economy and the continuous expansion of the logistics industry, containers, as an important logistics transportation tool, have been widely used globally. However, traditional containers still face some problems in practical use. For example, traditional containers typically use a single-unit design, which cannot meet the diverse needs of different scenarios. Furthermore, when multiple containers need to be spliced ​​or combined, existing connection methods are often complex and cumbersome, leading to low installation and dismantling efficiency and increasing construction and time costs.

[0003] Chinese Patent Publication No. CN212402140U discloses a tank container and its frame. The frame includes: two end frames spaced apart from each other, each end frame comprising a frame body and multiple first engaging portions protruding from the inner side of the frame body; multiple side beams respectively disposed between the two end frames, each side beam having a second engaging portion protruding towards the end frame at both ends, the second engaging portions and the first engaging portions being opposite each other; multiple connectors detachably connecting the first engaging portions and the second engaging portions; wherein, the second engaging portion has a receiving groove, and the first engaging portion has a corresponding protrusion that can extend into the receiving groove; or the second engaging portion has a protrusion, and the first engaging portion has a receiving groove that can correspondingly receive the protrusion. The end frames and side beams described above can be painted separately, achieving step-by-step manufacturing to quickly form a complete frame structure without the need for painting the entire frame, shortening working time and improving production efficiency. The above-described device achieves frame connection through the cooperation of the first engaging portions on the end frames and the second engaging portions on the side beams. Specifically, the second engaging portion has a receiving groove or a protrusion, and the first engaging portion has a corresponding protrusion or receiving groove. This design requires a complex mating relationship and necessitates a connector to detachably connect the first and second engaging portions. The overall structure is relatively complex, and manufacturing and assembly are challenging. Therefore, those skilled in the art urgently need to solve the aforementioned technical problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that the overall assembly of the above-mentioned prior art is complicated and the assembly is difficult when multiple boxes need to be spliced ​​together.

[0005] To solve the above-mentioned technical problems, the technical solutions adopted by this utility model are as follows:

[0006] A quick-release container includes a bottom fixing frame, a connecting assembly, and a container body. The container body includes a first container body, a second container body, and a third container body. The first container body and the third container body are located on both sides of the second container body. The connecting assembly is provided at the top joint of the second container body with the first container body and the third container body. The connecting assembly includes positioning parts and locking parts. The positioning parts are fixed to the top of the first container body, the second container body, and the third container body. The locking parts pass through two adjacent positioning parts. The bottom fixing frame is installed at the bottom of the first container body, the second container body, and the third container body by bolts.

[0007] By adopting the above technical solution, the positioning components in the connecting assembly are fixed to the top of the container, and the locking components pass through two adjacent positioning components, ensuring precise positioning between the containers. This design reduces the complex connection steps of traditional containers, improves assembly efficiency, and the bottom fixing frame is installed at the bottom of the container with bolts, further enhancing the stability of the overall structure. This design not only simplifies the bottom fixing process but also facilitates subsequent maintenance and adjustments. Through the design of the connecting assembly and the bottom fixing frame, three containers can be hoisted and spliced ​​at once. Compared to the traditional method of installing containers one by one, this design significantly shortens the installation time. The separation and assembly of the containers can be achieved simply by disassembling the locking components and bolts. Due to the ease of operation and the reduced need for manual intervention, labor costs are lowered. Container one, container two, and container three can be flexibly combined according to actual needs to meet the requirements of different sizes and functions.

[0008] Furthermore, the locking component includes a locking bolt and a locking hook, with two locking hooks provided in total. The locking bolt passes through both locking hooks, and the locking hooks are symmetrically arranged on the locking bolt.

[0009] By adopting the above technical solution, the locking claws are symmetrically arranged on the locking bolts, allowing the two claws to act evenly on adjacent positioning components. This design avoids structural deformation or damage caused by uneven force. The locking bolts, passing through the two locking claws and engaging with the positioning components, enable a tight connection between the enclosures. This design significantly improves the strength and rigidity of the enclosure joints. The symmetrical locking claw design effectively disperses vibration and impact forces, thereby improving the overall seismic performance of the structure. The opening and closing of the clamping claws can be achieved by rotating the locking bolts, allowing for quick assembly or disassembly of the enclosures. This design greatly simplifies the operation process and reduces manual intervention. The interlocking action between the locking claws and the positioning components effectively prevents the locking components from loosening due to vibration or external forces during transportation or use. When the enclosure is subjected to excessive external forces, the design of the locking bolts and locking claws provides a certain degree of buffering and protection, preventing damage to the enclosure due to excessive force. The symmetrical arrangement of the locking claws on the locking bolts effectively prevents the enclosure from tipping over due to imbalance during transportation or use.

[0010] Furthermore, the locking claw includes a connecting section and a positioning section. The connecting section is provided with a screw hole that matches the locking bolt. The positioning section has a concave structure and matches the positioning component.

[0011] By adopting the above technical solution, the positioning section has an overall concave structure that is compatible with the positioning component. This design ensures a precise snap-fit ​​between the locking claw and the positioning component, avoiding instability caused by positional misalignment. The large contact area between the concave positioning section and the positioning component effectively disperses stress, improving the strength and rigidity of the connection. The tight fit between the concave positioning section and the positioning component effectively absorbs and disperses vibration energy, thereby improving the overall seismic performance of the structure. The connecting section of the locking claw has screw holes that match the locking bolts, allowing the locking claw to be quickly installed onto the locking bolts. This design simplifies the installation process and improves operational efficiency. If fine-tuning of the box's position is required, the tightness of the locking claw can be adjusted by rotating the locking bolts, achieving precise positioning. The snap-fit ​​between the concave positioning section and the positioning component effectively prevents the locking claw from loosening due to vibration or external force during transportation or use. When the box is subjected to excessive external force, the locking claw design provides a certain degree of buffering and protection, preventing damage to the box due to excessive stress.

[0012] Furthermore, the positioning member has a connecting hole, and the positioning segment is engaged with the connecting hole. The connecting hole is located on the top of the positioning member and the outside of the housing.

[0013] By adopting the above technical solution, the snap-fit ​​design between the positioning section and the connecting hole makes the assembly process between the boxes much faster. Initial positioning is achieved simply by aligning the positioning section with the connecting hole and gently snapping it in. The snap-fit ​​design is simple and intuitive, reducing the need for specialized tools and techniques and minimizing manual intervention. Precise snap-fitting significantly shortens the assembly time, making it particularly suitable for scenarios requiring rapid assembly. If fine-tuning of the box's position is needed, precise adjustments can be made by slightly moving the positioning section within the connecting hole. The simple and intuitive operation allows workers to snap or separate the positioning section from the connecting hole with one hand, greatly facilitating on-site construction. The ease of operation and lack of complex tools or skills effectively reduce worker fatigue. The snap-fitting mechanism between the positioning section and the connecting hole effectively prevents loosening due to vibration or external forces during transportation or use.

[0014] Furthermore, the locking element engages with the adjacent positioning element.

[0015] Furthermore, the bottom fixing frame is also provided with at least 12 bottom locking parts. The size of the bottom fixing frame is adapted to the box body. The bottom locking parts are fixed to the bottom fixing frame by bolts, and the openings of the bottom locking parts face inward.

[0016] Furthermore, the bottom of each of the first, second, and third boxes is provided with four positioning components.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model ensures precise positioning and tight connection between the boxes through the design of positioning and locking components. The snap-fit ​​between the positioning section and the connecting hole can effectively prevent loosening due to vibration or external force during transportation or use. The locking bolt passes through two locking claws and cooperates with the positioning component to achieve a tight connection between the boxes, which improves the strength and rigidity of the box splice. The tight cooperation between the concave positioning section and the positioning component can effectively absorb and disperse vibration energy, thereby improving the seismic performance of the overall structure.

[0019] 2. This utility model uses a snap-fit ​​design between the positioning segment and the connecting hole to make the splicing process between the boxes faster. The initial positioning can be completed simply by aligning the positioning segment with the connecting hole and snapping it in. Since the snap-fit ​​design is simple and intuitive to operate, it reduces the requirements for professional tools and techniques and reduces the degree of manual intervention. Through precise snap-fit ​​cooperation, the splicing time of the boxes can be significantly shortened, which is especially suitable for scenarios that require rapid assembly.

[0020] 3. The first, second, and third boxes of this utility model can be flexibly combined according to actual needs to meet the requirements of different scales and functions. The bottom fixing frame can be designed to be adapted to the specifications of the boxes, thereby fixing the boxes together and realizing the one-time hoisting of multiple boxes.

Detailed Implementation

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and specific preferred embodiments.

[0028] In the description of this utility model, it should be understood that the terms "left side," "right side," "upper part," "lower part," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. "First," "second," etc., do not indicate the importance of the components, and therefore should not be construed as a limitation of this utility model. The specific dimensions used in this embodiment are only for illustrating the technical solution and do not limit the protection scope of this utility model.

[0029] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As can be seen, this utility model discloses a quick-release container, mainly comprising three core components: a bottom fixing frame 1, a connecting assembly 2, and a container body 3. The bottom fixing frame 1 is a rectangular steel structure frame, the length and width of which match the bottom dimensions of the three container bodies 3 joined together. Twelve symmetrically distributed bottom locking members 11 are welded to the inner side of the bottom fixing frame 1, with four bottom locking members 11 located at the four corners of the frame, and the remaining eight bottom locking members 11 equidistantly distributed along the length of the bottom fixing frame 1. The openings of all bottom locking members 11 face the central axis of the frame. The bottom of the bottom fixing frame 1 is provided with anti-slip textures to enhance stacking stability.

[0030] The housing 3 consists of housing 1 (31), housing 2 (32), and housing 3 (33), all three housings 3 being independently welded steel shells. Housing 2 (32) serves as the central unit, with concave-convex guide structures on both end faces that mate with housing 1 (31) and housing 3 (33) to ensure precise positioning during assembly. Positioning elements 21 are provided at the top corners of the three housings 3. The vertical sections of the positioning elements 21 are welded to the outer wall of the housing 3, and the top of the positioning elements 21 and near the outer side of the housing 3 have connecting holes 211.

[0031] The connecting assembly 2 includes a positioning element 21 and a locking element 22. During assembly, the tops of housing 1 (31), housing 3 (33), and housing 2 (32) are aligned, bringing the horizontal sections of the positioning elements 21 of adjacent housings 3 closer together. At this time, the positioning section 2222 of the locking element 22 engages from top to bottom into the connecting holes 211 of the two adjacent positioning elements 21. The locking claws 222 are forged from high-strength alloy, and the connecting section 2221 of the locking claws 222 has threaded through holes that match the locking bolts 221. By tightening the locking bolts 221, the two symmetrically arranged locking claws 222 move towards each other, thereby clamping the horizontal sections of the positioning elements 21 to achieve a rigid connection. In a preferred embodiment, the end of the locking bolts 221 is provided with a hexagonal nut with an anti-loosening washer to ensure that it does not rotate after tightening.

[0032] The connection between the bottom fixed frame 1 and the box 3 is achieved through two sets of standardized interfaces: positioning parts 21 are welded to the four corners of the bottom of each box 3, and bottom locking parts 11 are welded to the bottom fixed frame 1; the bottom locking parts 11 are snapped into the connecting holes 211 of the positioning parts 21, and the bottom locking parts 11 are installed in the bottom fixed frame 1 by bolts. During installation, the bottom of the box 3 is first aligned with the bottom fixed frame 1, and then bolts 12 are used to pass through the bottom fixed frame 1, thereby fixing the box 31, box 32 and box 33 together.

[0033] Working principle: Each box 3 has a positioning component 21 welded to its top corner. The vertical section of the positioning component 21 is fixed to the outer wall of the box 3. The top and the outer side near the box 3 have connecting holes 211. After aligning box 1 31 and box 3 33 with box 2 32, the positioning components 21 of adjacent boxes 3 come into contact. The positioning section 2222 of the locking component 22 engages in the connecting holes 211 of two adjacent positioning components 21. The locking claw 222 is forged from high-strength alloy. The connecting section 2221 of 222 is provided with a threaded through hole that matches the locking bolt 221. By tightening the locking bolt 221, the two symmetrically arranged locking claws 222 will move towards each other and clamp the positioning piece 21, thereby connecting the top of the box 3. The end of the locking bolt 221 is provided with a hexagonal nut with an anti-loosening washer to ensure that it does not rotate after tightening. Positioning pieces 21 are welded to the four corners of the bottom of each box 3, and bottom locking pieces 11 are welded to the bottom fixed frame 1.

[0034] During installation, the bottom of the box 3 is aligned with the bottom fixing frame 1, the bottom locking piece 11 is engaged in the connecting hole 211 of the positioning piece 21, and the box 31, box 32 and box 33 are fixed together by bolts 12 passing through the bottom fixing frame 1. The bottom of the bottom fixing frame 1 is provided with anti-slip texture to enhance stacking stability. Box 1 31, box 2 32 and box 3 33 are all independently welded steel shells, which are convenient for individual transportation and assembly. Box 2 32 serves as the central unit and has concave and convex guide structures on both end faces to ensure accurate positioning during splicing. Through the cooperation of the positioning piece 21 and the locking piece 22, the adjacent box 3 can be quickly aligned and rigidly connected. The bottom fixing frame 1 and the box 3 are connected together by the bottom locking piece 11.

[0035] When in use, the bottom fixed frame 1 serves as a supporting structure for the box 3, providing a stable base. Lifting rings or lifting lugs can be pre-set on the bottom fixed frame 1 to facilitate the rapid movement of the entire device by external transportation equipment. The anti-slip texture of the bottom fixed frame 1 ensures that the box will not slide due to vibration or tilting during the movement. Lifting lugs are also set on the top of the box 3 to facilitate the lifting of the three boxes 3.

[0036] The connecting component 2 is fastened with bolts, which facilitates quick disassembly and reinstallation. The positioning parts 21 at the top and bottom of the box 3 ensure the stability of the box 3. The high-strength alloy material and anti-loosening design of the locking claw 222 further enhance the reliability of the connection. The anti-slip texture and overall rigidity design of the bottom fixing frame 1 improve the stability during the hoisting process. The reasonable layout of the hoisting points ensures uniform force distribution and avoids safety hazards caused by local stress concentration.

[0037] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various equivalent transformations can be made to the technical solutions of the present invention, and all such equivalent transformations fall within the protection scope of the present invention.
