Description

Technical Field

[0001] This invention relates to the field of storage and transportation equipment, and more particularly to a storage and transportation device. Background Technology

[0002] Currently, the fastening mechanisms used in storage and transportation equipment mostly employ multiple modular latches. To ensure the fastening strength and the pressure resistance and sealing performance of the storage and transportation equipment, each piece of equipment needs to be equipped with multiple latches, which are arranged around the edge of the box opening. As a result, the number of latches is large. When the storage and transportation equipment needs to be opened and closed, that is, when the box cover and the box body need to be opened and closed, workers need to operate multiple latches one by one to complete the opening and closing operation of the storage and transportation equipment. Moreover, due to structural limitations, the fastening mechanisms installed in the existing storage and transportation equipment are not easy to match with automated equipment to achieve automated opening and closing operations because the latches need to be operated one by one. Summary of the Invention

[0003] The purpose of this invention is to provide a storage and transportation device that solves the problem of cumbersome, time-consuming, and labor-intensive operation when opening and closing boxes in existing storage and transportation devices.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution.

The locking mechanism includes a latching structure mounted on the box body along its inner edge. The latching structure includes a latching shaft extending vertically and a latching member rotatable about the axis of the latching shaft. The locking mechanism also includes a long-side connecting rod extending along the long side of the inner edge of the box body and a wide-side connecting rod extending along the wide side of the inner edge of the box body. The long-side connecting rod and the adjacent wide-side connecting rod are connected by a transition connecting rod, which is hinged to both the long-side connecting rod and the wide-side connecting rod. The transition connecting rod is rotatably mounted on the box body about its inner axis of rotation. The long-side connecting rod and the wide-side connecting rod are movably connected to the inner end of the latching member corresponding to their respective edges. The locking mechanism also includes an operating handle, which is rotatably mounted on the box body and has its inner end hinged to a connecting rod.

[0006] Furthermore, the long-side connecting rod is a polygonal shape.

[0007] Furthermore, the long-side connecting rod includes a long parallel segment in the middle of the long-side connecting rod and short parallel segments at both ends of the long-side connecting rod. The long parallel segment and the short parallel segment are parallel to each other, and there is also an inclined segment between the long parallel segment and the short parallel segment that connects the long parallel segment and the short parallel segment.

[0008] Furthermore, the operating handle is located at the long parallel section of the long side connecting rod.

[0009] Furthermore, both the long and wide connecting rods are equipped with pins at the corresponding locking positions, and the inner end of the locking member is movably connected to the pin.

[0010] Furthermore, the end of the locking component that is movably connected to the pin has a waist-shaped groove, and the pin can slide within the waist-shaped groove.

[0011] Furthermore, the longer connecting rod has more locking devices than the wider connecting rod.

[0012] Furthermore, the transition link is a T-shaped link, which includes a first side that is connected to the long side link and the wide side link at both ends, and a second side that extends inward perpendicular to the first side. The rotation axis of the T-shaped link is located on the second side.

[0013] Furthermore, a clearance opening is provided on the housing for the operating handle to extend out, and the pivot of the operating handle is fixed to the side wall of the housing.

[0017] The features and performance of the present invention will be further described in detail below with reference to embodiments.

[0018] This invention proposes a storage and transportation device, including a box and a lid. A fastening mechanism is provided within the box, comprising a locking structure for mounting on the box along its inner edge. The locking structure includes a vertically extending locking shaft and a locking element rotatable about the axis of the locking shaft. In use, a long-side connecting rod and a wide-side connecting rod are provided along the inner edge of the box. A transition connecting rod is hinged at the connection between the long-side and wide-side connecting rods. The transition connecting rod is rotatably mounted on the box about its inner axis. The long-side and wide-side connecting rods are movably connected to the inner ends of the locking elements corresponding to their respective edges. The device also includes an operating handle, which is rotatably mounted on the box and has its inner end hinged to a connecting rod. Operating the operating handle allows all connecting rods to move synchronously, thereby driving all locking elements to move synchronously.

[0019] Based on the above concept, the present invention provides various embodiments of storage and transportation equipment for illustration.

[0020] In a basic embodiment, such as Figure 3-5 As shown in Figures 7 and 8, the storage and transportation equipment includes a box body 8 and a box cover 10. A fastening mechanism is provided in the box body 8 to lock the box body 8 and the box cover 10 when they are in the closed state.

[0021] The fastening mechanism includes a locking structure for mounting on the box 8 along the inner edge of the box 8. The locking structure includes a locking shaft 6 extending vertically and a locking member 4 that can rotate around the axis of the locking shaft 6. The locking shaft 6 is fixedly mounted on the bottom of the box 8. The fastening mechanism also includes a long side connecting rod 2 extending along the long side of the inner edge of the box 8 and a wide side connecting rod 1 extending along the wide side of the inner edge of the box 8 when the fastening mechanism is used. The long side connecting rod 2 and the adjacent wide side connecting rod 1 are connected by a transition connecting rod. The transition connecting rod is hinged to the long side connecting rod 2 and the wide side connecting rod 1 respectively. The transition connecting rod is rotatably mounted on the box 8 around the rotation axis located on its inner side. The long side connecting rod 2 and the wide side connecting rod 1 are movably connected to the inner end of the locking member 4 corresponding to their respective edges. The fastening mechanism also includes an operating handle 5, which is rotatably mounted on the box 8 and whose inner end is hinged to a certain connecting rod.

[0022] When it is necessary to lock the box body 8 and the box cover 9, the operating handle 5 is operated. The operating handle 5 drives all the connecting rods to move synchronously, which can further push all the locking fasteners 4 to move synchronously. This enables the storage and transportation equipment to open and close quickly, which is simple to operate and saves time and manpower.

[0023] Based on the above embodiments, the long-side connecting rod 2 can be configured as a single curved segment, which is connected to the wide-side connecting rod 1 via a transition connecting rod during use. In a preferred embodiment, such as... Figure 1-5 As shown, the long side connecting rod 2 includes a long parallel segment in the middle of the long side connecting rod 2 and short parallel segments at both ends of the long side connecting rod 2. The long parallel segment and the short parallel segment are parallel to each other. There is also an inclined segment between the long parallel segment and the short parallel segment that connects the long parallel segment and the short parallel segment. This arrangement can make the long side connecting rod 2 have a better transmission effect when in use.

[0024] In the above embodiments, such as Figure 1-5 As shown in Figure 7, the long side of the storage and transportation equipment is convex. Adaptively, the long side connecting rod 2 is set as a broken line, and the wide side connecting rod 1 is set as a straight line. In other embodiments, the long side connecting rod 2 can be set as a curved line or a straight line, and the wide side connecting rod 1 can be set as a curved line or a broken line, to suit different storage and transportation equipment with corresponding shapes.

[0025] Based on the above embodiments, the operating handle 5 can be disposed on the wide-side connecting rod 1, or at the short parallel section of the long-side connecting rod 2. In another embodiment, two or three operating handles 5 can be disposed, respectively on the wide-side connecting rod 1, at the short parallel section of the long-side connecting rod 2, and at the long parallel section of the long-side connecting rod 2. In a preferred embodiment, such as... Figure 1-2As shown, there is one operating handle 5. When the storage and transportation equipment is a cuboid, the operator usually operates from the long side. The operating handle 5 is set at the long parallel section of the long side connecting rod 2, so that the operation can be completed in the same way. At the same time, the operator can operate the operating handle 5 conveniently.

[0026] In the above embodiments, a preferred embodiment is as follows: Figure 2 , 5 As shown in Figure 6, both the long side connecting rod 2 and the wide side connecting rod 1 are provided with a pin at the corresponding position of the locking element 4. The inner end of the locking element 4 is movably connected to the pin. Thus, when the long side connecting rod 2 and the wide side connecting rod 1 move, the pin can drive the locking element 4 to move synchronously.

[0027] Based on the above embodiments, the end of the locking member 4 that is movably connected to the detent has a hole larger than the diameter of the detent. The detent passes through the hole on the locking member 4, thus achieving the movable connection between the locking member 4 and the detent. In a preferred embodiment, such as... Figure 1-2 As shown, the end of the locking fastener 4 that is movably connected to the pin has an oblong groove, and the pin can slide in the oblong groove. This design can prevent the linkage from jamming during movement, which would cause the opening and closing of the box to be unsmooth.

[0028] Based on the above embodiments, the locking element 4 connected to both the long side connecting rod 2 and the wide side connecting rod 1 can be one, or the locking element 4 connected to the wide side connecting rod 1 can be more than the locking element 4 connected to the long side connecting rod 2. In a preferred embodiment, such as Figure 1-5 As shown, the number of locking fasteners 4 connected to the long side connecting rod 2 is greater than the number of locking fasteners 4 connected to the wide side connecting rod 1. With this arrangement, the multiple locking fasteners 4 are more evenly distributed on the connecting rod, resulting in a better locking effect.

[0029] Preferred, such as Figure 1-2 As shown, four locking fasteners 4 are connected to the long side connecting rod 2, and one locking fastener 4 is connected to the wide side connecting rod 1.

[0030] Based on the above embodiments, the transition link can be configured as a Y-shaped link, with the two closer sides of the Y-shaped link hinged to the long side link 2 and the wide side link 1 respectively, and the rotation axis of the Y-shaped link located on the other side. In a preferred embodiment, such as... Figure 1-5 As shown, the transition link is a T-shaped link 3. The T-shaped link 3 includes a first side that is connected to the long side link 2 and the wide side link 1 at both ends, and a second side that extends inward perpendicular to the first side. The rotation axis of the T-shaped link 3 is located on the second side.

[0031] Based on the above embodiments, such as Figure 2 As shown, in a preferred embodiment, the T-shaped connecting rod 3 is connected to the housing 8 via a support 7, and the axis of the support 7 is the rotation axis of the T-shaped connecting rod 3.

[0032] Based on the above embodiments, in a preferred embodiment, such as Figure 5 , 7 As shown, a clearance opening 9 is provided on the side wall of the storage and transportation equipment box 8 for the operating handle 5 to extend out. The rotating shaft of the operating handle 5 is fixedly installed on the side wall of the box 8, which makes it more convenient to operate when the storage and transportation equipment needs to be opened and closed.

[0033] When using the storage and transportation equipment of the present invention, when it is necessary to connect the box body 8 and the box cover 10 as follows: Figure 7 When closing and fastening as shown, first align the box body 8 and the box cover 10, then by turning the operating handle 5 extending from the clearance opening 9 on the side wall of the box body 8, the pin on the connecting rod slides in the waist-shaped groove of the locking element 4, thereby pushing all the locking elements 4 to lock the box body 8 and the box cover 10 together. When locked, as shown... Figure 3 , 6 As shown, the locking fastener 4 presses the inner flange 12 of the lid against the inner flange 11 of the box body, so that the box body 8 and the lid 10 are locked together.

[0034] When it is necessary to separate the box body 8 from the box lid 10, the operating handle 5 is then turned, and the connecting rod pin slides in the waist-shaped groove of the locking element 4, thereby pushing all the locking elements 4 to rotate so that they are in the position shown. Figure 4 As shown in the diagram, the box body 8 and the box lid 10 can be separated.

[0035] The storage and transportation equipment of the present invention can also be linked with automated equipment. The automated equipment is connected to the operating handle 5, which enables convenient automated opening and closing of the box.

[0036] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. The scope of patent protection of the present invention shall be determined by the claims. Similarly, any equivalent structural changes made based on the description and drawings of the present invention shall also be included within the scope of protection of the present invention.
