Description

Technical Field

[0001] This invention relates to the field of container support equipment technology, specifically to a support mechanism for containers and a container. Background Technology

[0002] Currently, the support devices used for vehicles and other transport equipment are generally vertically arranged, extending outwards to provide support during operation. One type uses vertically arranged jacks that can extend outwards in a straight line or swing outwards before being lowered, requiring two steps to complete self-support. Another type uses a support device that extends outwards directly in a diagonal straight line or unfolds outwards via a linkage, completing self-support in a single step.

[0003] When using these two types of support devices, a large installation space is required in the height direction of the container. When using special containers for transportation, due to the limited space (width and height) inside the special containers, there is only enough space in the longitudinal direction, which makes it difficult to install and the support devices may not work properly. Summary of the Invention

[0004] In view of the deficiencies in the prior art, the purpose of this invention is to provide a support mechanism and a container for containers, which can solve the problems of difficulty in installation and difficulty in normal operation of the support device in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] On one hand, this application provides a support mechanism for a container, which includes a plurality of support units, each of the support units comprising:

[0007] A jack is used to be installed on the inside of the vertical projection of the box body;

[0008] A telescopic rotating structure is used to connect to the housing, and the telescopic end is connected to the jack. The telescopic rotating structure extends in a direction perpendicular to the extension direction of the jack. The telescopic rotating structure is used to extend the jack out of the housing and rotate the jack so that its extension direction is perpendicular to the ground.

[0009] Based on the above technical solutions,

[0010] In some alternative embodiments, the telescopic rotation structure includes:

[0011] A base is provided on the box body and has a through hole inside, the direction of which is the same as the telescopic rotation structure's telescopic direction.

[0012] An extension arm is slidably disposed within the through hole and rotatable relative to the base, the end of the extension arm being connected to the jack;

[0013] A drive assembly for driving the extension arm to extend out of the through hole and rotate when it is outside the housing.

[0014] In some alternative solutions, the extendable arm is provided with a guide groove, which includes a straight section and a spiral section. The base is provided with a fixed guide pin, which is slidably disposed in the guide groove. When the extendable arm extends, the fixed guide pin moves in the guide groove, and when passing through the spiral section, the extendable arm rotates in the through hole.

[0015] In some alternative solutions, the driving component includes:

[0016] A sleeve rod, with its end fixedly installed;

[0017] A push rod, which is telescopically disposed within the sleeve rod, and whose end is rotatably connected to the extendable arm.

[0018] In some alternative solutions, four support units are included, divided into two groups of two. The extension arms of the two support units in each group extend in opposite directions. A drive motor is provided on the base of one support unit in each group. The two support units in each group share a drive motor, which is used to drive the push rod to extend from the sleeve rod.

[0019] On the other hand, this application also provides a container comprising:

[0020] Box;

[0021] Multiple support units, each of the support units comprising:

[0022] - A jack, which is located on the inner side of the vertical projection of the box body;

[0023] - A telescopic rotating structure is connected to the housing, and the telescopic end is connected to the jack. The telescopic rotating structure extends in a direction perpendicular to the extension direction of the jack. The telescopic rotating structure is used to extend the jack out of the housing and rotate the jack so that its extension direction is perpendicular to the ground.

[0024] In some alternative embodiments, the telescopic rotation structure includes:

[0025] A base is provided on the box body and has a through hole inside, the direction of which is the same as the telescopic rotation structure's telescopic direction.

[0026] An extension arm is slidably disposed within the through hole and rotatable relative to the base, the end of the extension arm being connected to the jack;

[0027] A drive assembly for driving the extension arm to extend out of the through hole and rotate when it is outside the housing.

[0028] In some alternative solutions, the housing is provided with an outer cover located outside the jack, and the support unit is provided with a linkage opening mechanism. The linkage opening mechanism is connected to the outer cover and is used to open the outer cover in conjunction with the extension arm during the extension process.

[0029] In some alternative solutions, the base is provided with a sliding hole along the extension direction of the extension arm, the outer cover is rotatably connected to the housing, and the linkage opening mechanism includes:

[0030] A slider, which passes through the sliding hole and is connected to the extending arm, and can slide within the sliding hole;

[0031] The connecting rod has one end hinged to the outer cover via a first hinge, and the other end hinged to the slider via a second hinge.

[0032] In some alternative solutions, the lower end of the slider is provided with a cylindrical shaft, the extended arm is provided with an elastic stop, the elastic stop is provided with a latch, the latch faces away from the end of the jack, the open end of the latch is provided with a latching block, the cylindrical shaft is locked in the latch and located inside the latching block, and when the outer cover is opened to a set angle, the cylindrical shaft disengages from the latch.

[0033] Compared with the prior art, the advantages of the present invention are as follows:

[0034] When using this support mechanism for containers, a telescopic rotating structure is connected to the container body. The jacks extend outside the container via this structure, and are rotated outside the container so that their extension direction is perpendicular to the ground. The jacks extend and contact the ground, and the jacks in multiple support units collectively support the container body. Because the jacks are located inside the vertical projection of the container body, and the telescopic rotating structure allows the jacks to extend outside the container and rotate so that their extension direction is perpendicular to the ground, the vertical space occupied by the jacks is reduced. This makes it suitable for special containers with limited installation space, solving the problems of difficult installation and malfunctioning support devices in existing technologies.

[0043] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0044] The following detailed description, in conjunction with the accompanying drawings, provides an embodiment of a support mechanism for a container and a container according to the present invention.

[0045] like Figure 1 , Figure 2 and Figure 6 As shown, this application provides a support mechanism for a container, which includes multiple support units. Each support unit includes a jack 1 and a telescopic rotating structure 3. The jack 1 is used to be installed on the inner side of the container body 2 in the vertical direction projection. The telescopic rotating structure 3 is used to connect with the container body 2, and the telescopic end is connected to the jack 1. The telescopic rotating structure 3 is perpendicular to the extension direction of the jack 1. The telescopic rotating structure 3 is used to extend the jack 1 outside the container body 2 and rotate the jack 1 so that its extension direction is perpendicular to the ground.

[0046] When using this support mechanism for containers, the telescopic rotating structure 3 is connected to the container body 2. The jack 1 extends outside the container body 2 via the telescopic rotating structure 3, and is rotated outside the container body 2 so that the extension direction of the jack 1 is perpendicular to the ground. The jack 1 extends and contacts the ground, and the jacks 1 in multiple support units collectively support the container body 2. Because the jack 1 is located inside the vertical projection of the container body 2, and the telescopic rotating structure 3 can extend the jack 1 outside the container body 2 and rotate it so that its extension direction is perpendicular to the ground, the vertical space occupied by the jack 1 can be reduced. This makes it suitable for special containers with limited space, solving the problems of difficult installation and malfunctioning support devices in existing technologies.

[0047] like Figure 1 , Figure 2 and Figure 5 As shown, in some optional embodiments, the telescopic rotating structure 3 includes:

[0048] The base 31 is used to be mounted on the box 2 and has a through hole 313 inside. The direction of the through hole 313 is the same as the telescopic rotation structure 3 telescopic direction.

[0049] The extension arm 32 is slidably disposed in the through hole 313 and can rotate relative to the base 31. The end of the extension arm 32 is connected to the jack 1.

[0050] Drive assembly 4, which drives the extension arm 32 to extend out of the through hole 313 and rotate when it is outside the housing 2.

[0051] In this embodiment, the structure of the telescopic rotating structure 3 is specifically described. The telescopic rotating structure 3 includes a base 31, an extension arm 32, and a drive assembly 4. The base 31 is used to be mounted on the housing 2 and has a through hole 313 inside. The direction of the through hole 313 is the same as the telescopic direction of the telescopic rotating structure 3. The extension arm 32 is slidably disposed in the through hole 313 and can rotate relative to the base 31. The end of the extension arm 32 is connected to the jack 1. The drive assembly 4 is used to drive the extension arm 32 to extend out of the through hole 313 and rotate when it is outside the housing 2. The structure is simple and easy to implement.

[0052] like Figure 2 and Figure 4 As shown, in some optional embodiments, the extendable arm 32 is provided with a guide groove 321, which includes a straight section and a spiral section. The base 31 is provided with a fixed guide pin 311, which is slidably disposed in the guide groove 321. When the extendable arm 32 extends, the fixed guide pin 311 moves in the guide groove 321, and when passing through the spiral section, the extendable arm 32 rotates in the through hole 313.

[0053] In this embodiment, the method of rotating the extension arm 32 is described. The extension arm 32 is provided with a guide groove 321, which includes a straight section and a spiral section. The base 31 is provided with a fixed guide pin 311, which is slidably disposed in the guide groove 321. When the extension arm 32 extends, the fixed guide pin 311 moves in the guide groove 321. When passing through the spiral section, the extension arm 32 rotates in the through hole 313. The structure is simple, and the rotation of the extension arm 32 can be achieved by telescopically extending the extension arm 32, which simplifies the structure and makes it easier to manufacture.

[0054] In this example, the straight segment is divided into two segments by the spiral segment. When the fixed guide pin 311 moves in the first straight segment, the extendable arm 32 extends, extending the jack 1 beyond the vertical projection of the box 2. When the fixed guide pin 311 passes through the spiral segment, the extendable arm 32 rotates in the through hole 313, and the jack 1 rotates until its extension direction is perpendicular to the ground. When the fixed guide pin 311 moves in the second straight segment, the extendable arm 32 continues to extend to reserve space in the carriage when the transport vehicle loads the box 2.

[0055] like Figure 1 and Figure 5 As shown, in some optional embodiments, the driving component 4 includes:

[0056] Sleeve rod 41, its end is fixedly installed;

[0057] The push rod 42 is telescopically disposed within the sleeve 41, and its end is rotatably connected to the extension arm 32.

[0058] In this embodiment, the structure of the drive assembly 4 is specifically described. The drive assembly 4 includes a sleeve rod 41 and a push rod 42. The end of the sleeve rod 41 is fixedly disposed, and the push rod 42 is telescopically disposed inside the sleeve rod 41. Its end is rotatably connected to the extension arm 32. When the extension arm 32 rotates, it will not affect the normal operation of the drive assembly 4. The structure is simple and easy to implement.

[0059] In this example, push rod 42 is rotatably connected to extension arm 32 via thrust bearing 5. Extension arm 32 has a mounting hole 322 at its extended end. Thrust bearing 5 is installed in mounting hole 322. End cap 323 presses the outer ring of thrust bearing 5 to prevent thrust bearing 5 from dislodging from mounting hole 322. The end of push rod 42 is a stepped shaft. The smaller diameter part extends into the inner ring of thrust bearing 5, and the larger diameter part has a shoulder 421. Shoulder 421 contacts thrust bearing 5. The inner ring of thrust bearing 5 is pressed by bushing 324 and nut 325.

[0060] like Figure 1 As shown, in some optional embodiments, four support units are included, divided into two groups of two. The extension arms 32 of the two support units in each group extend in opposite directions. A drive motor 6 is provided on the base 31 of one support unit in each group. The two support units in each group share a drive motor 6. The drive motor 6 is used to drive the push rod 42 to extend out of the sleeve rod 41.

[0061] In this embodiment, the support mechanism for the container includes four support units, which are divided into two groups of two. The extension arms 32 of the two support units in each group extend in opposite directions. A drive motor 6 is provided on the base 31 of one support unit in each group. The two support units in each group share one drive motor 6. The drive motor 6 is used to drive the push rod 42 to extend the sleeve rod 41. Using four support units provides better support for the container 2. The fact that the two support units in each group share one drive motor 6 can reduce the number of drive motors 6, simplify the structure, and make manufacturing more convenient.

[0062] like Figure 1 , Figure 2 and Figure 6 As shown, on the other hand, this application also provides a container, which includes the above-mentioned support mechanism for the container, specifically including a container body 2 and multiple support units. Each support unit includes a jack 1 and a telescopic rotating structure 3, wherein the jack 1 is disposed on the inner side of the vertical projection of the container body 2; the telescopic rotating structure 3 is connected to the container body 2, and the telescopic end is connected to the jack 1. The telescopic rotating structure 3 is perpendicular to the extension direction of the jack 1. The telescopic rotating structure 3 is used to extend the jack 1 outside the container body 2 and rotate the jack 1 so that its extension direction is perpendicular to the ground.

[0063] When using this container, the telescopic rotating structure 3 is connected to the container body 2. The jack 1 extends outside the container body 2 via the telescopic rotating structure 3, and is rotated outside the container body 2 so that the extension direction of the jack 1 is perpendicular to the ground. The jack 1 extends and contacts the ground, and the jacks 1 in multiple support units collectively support the container body 2. Because the jack 1 is located inside the vertical projection of the container body 2, and the telescopic rotating structure 3 can extend the jack 1 outside the container body 2 and rotate it so that its extension direction is perpendicular to the ground, the vertical space occupied by the jack 1 can be reduced. This makes it suitable for special containers with limited space, solving the problems of difficult installation and malfunctioning support devices in existing technologies.

[0064] like Figure 1 , Figure 2 and Figure 5 As shown, in some optional embodiments, the telescopic rotating structure 3 includes:

[0065] The base 31 is set on the box 2 and has a through hole 313 inside. The direction of the through hole 313 is the same as the telescopic rotation structure 3 telescopic direction.

[0066] The extension arm 32 is slidably disposed in the through hole 313 and can rotate relative to the base 31. The end of the extension arm 32 is connected to the jack 1.

[0067] Drive assembly 4, which drives the extension arm 32 to extend out of the through hole 313 and rotate when it is outside the housing 2.

[0068] In this embodiment, the structure of the telescopic rotating structure 3 is specifically described. The telescopic rotating structure 3 includes a base 31, an extension arm 32, and a drive assembly 4. The base 31 is disposed on the housing 2 and has a through hole 313 inside. The direction of the through hole 313 is the same as the telescopic direction of the telescopic rotating structure 3. The extension arm 32 is slidably disposed in the through hole 313 and can rotate relative to the base 31. The end of the extension arm 32 is connected to the jack 1. The drive assembly 4 is used to drive the extension arm 32 to extend out of the through hole 313 and rotate when it is outside the housing 2. The structure is simple and easy to implement.

[0069] like Figure 2 , Figure 4 and Figure 6 As shown, in some optional embodiments, the housing 2 is provided with an outer cover 7 located outside the jack 1, and the support unit is provided with a linkage opening mechanism 8. The linkage opening mechanism 8 is connected to the outer cover 7 and is used to open the outer cover 7 in conjunction with the extension arm 32 during the extension process.

[0070] In this embodiment, an outer cover 7 is provided on the housing 2, located outside the jack 1. A linkage opening mechanism 8 is provided on the support unit. The linkage opening mechanism 8 is connected to the outer cover 7 and is used to open the outer cover 7 in conjunction with the extension arm 32 during the extension process. When the jack 1 is inside the housing 2, the outer cover 7 needs to be opened before the jack 1 extends out of the housing 2. The linkage opening mechanism 8 can open the outer cover 7 in conjunction with the extension arm 32 during the extension process, making the process more convenient.

[0071] like Figure 2 and Figure 4 As shown, in some optional embodiments, the base 31 is provided with a sliding hole 312 along the extension direction of the extension arm 32, the outer cover 7 is rotatably connected to the housing 2, and the linkage opening mechanism 8 includes:

[0072] The slider 81 passes through the sliding hole 312 and is connected to the extension arm 32, and can slide within the sliding hole 312;

[0073] The connecting rod 82 has one end hinged to the outer cover 7 via the first hinge 71, and the other end hinged to the slider 81 via the second hinge 811.

[0074] In this embodiment, a sliding hole 312 along the extension direction of the extension arm 32 is provided on the base 31. The outer cover 7 is rotatably connected to the box body 2. The linkage opening mechanism 8 includes a slider 81 and a connecting rod 82. The slider 81 passes through the sliding hole 312 and is connected to the extension arm 32, and can slide in the sliding hole 312. One end of the connecting rod 82 is hinged to the outer cover 7 through a first hinge 71, and the other end is hinged to the slider 81 through a second hinge 811. When the slider 81 is located at the end of the sliding hole 312 close to the jack 1, the connecting rod 82 opens the outer cover 7 through the first hinge 71. The structure is simple and easy to implement.

[0075] In this example, the outer cover 7 is rotatably connected to the housing 2 via a third hinge 21. A spring is also provided on the base 31 to hold the slider 81 away from the jack 1, and the spring force keeps the outer cover 7 in the open position.

[0076] like Figures 2-4 As shown, in some optional embodiments, the lower end of the slider 81 is provided with a cylindrical shaft 812, the extended arm 32 is provided with an elastic stop 83, the elastic stop 83 is provided with a latch, the latch faces away from the end of the jack 1, the open end of the latch is provided with a latching block, the cylindrical shaft 812 is latched in the latch and located inside the latching block, and when the outer cover 7 is opened to a set angle, the cylindrical shaft 812 disengages from the latch.

[0077] In this embodiment, a cylindrical shaft 812 is provided at the lower end of the slider 81, and an elastic stop 83 is provided on the extension arm 32. The elastic stop 83 is provided with a latch, which faces the end away from the jack 1. A latch is provided at the open end of the latch. The cylindrical shaft 812 is locked in the latch and located inside the latch. When the outer cover 7 is opened to a set angle, the slider 81 is located at the end of the sliding hole 312 close to the jack 1. The sliding hole 312 restricts the slider 81 from continuing to slide. The extension arm 32 drives the elastic stop 83 to continue to move, and the cylindrical shaft 812 disengages from the latch. When the jack 1 is retracted, the slider 81 is located at the end of the sliding hole 312 away from the jack 1, and the cylindrical shaft 812 is located outside the latch. The sliding hole 312 restricts the slider 81 from continuing to slide. The extension arm 32 drives the elastic stop 83 to continue to move, and the cylindrical shaft 812 enters the elastic stop 83 from the latch.

[0078] In this example, the opening end of the bayonet is provided with two blocks. The blocks are provided with an inner stop 831 and an outer stop 832. Both the inner stop 831 and the outer stop 832 are used to abut against the cylindrical shaft 812. When the slider 81 is located at the end of the sliding hole 312 close to the jack 1, the cylindrical shaft 812 abuts against the inner stop 831. When the slider 81 is located at the end of the sliding hole 312 away from the jack 1, the cylindrical shaft 812 abuts against the outer stop 832.
