Abstract
Description
Technical Field
[0001] The utility model belongs to the field of logistics transportation equipment, and specifically relates to a foldable container. Background Art
[0002] The existing goods that are stored and transported in metal cages, such as commercial cigarettes, processed beef and mutton, potted flowers, etc., are large in size and heavy in weight, and are afraid of being squeezed and bumped. Secondly, due to the volume and weight of the storage unit, casters are required to be set at the bottom of the container to help the container move, so as to reduce the labor intensity of the operator in the process of moving the container. However, for such large movable metal containers, the base and side panels of the container are generally assembled by bending and welding metal steel pipes and wires. The characteristic of metal parts is high density, and the metal parts that can be welded and fixed are limited to metal materials. Ultimately, the storage container is heavy and difficult to operate and move after loading. The storage and transportation process (from the warehouse to the container) is time-consuming and labor-intensive, and the efficiency is relatively low.
[0003] Secondly, since most of the side panels of this type of metal container are metal steel pipes and grid-shaped metal mesh plates, the unit mass is large. Especially in order to maximize the container loading rate, this type of metal container is often designed to meet the maximum inner height of the container (usually about 2.3 meters). Such a metal cage truck with a large height is heavy, has a high center of gravity, is difficult to move, and has a safety hazard of collapse during the movement.
[0004] In addition, metal containers like these are usually transported in containers, vans, small vans, etc. during the transshipment process. However, these containers often have a fixed height. When they are transported in different vans (within height), their loading is limited, and they have to be stored and transported by turning over and changing boxes, which greatly reduces the turnover efficiency of containers.

[0059] For the convenience of description, the side where the door panel 22 of the folding container 100 is located is referred to as the front side. Figure 1-18 As shown, the foldable container 100 of the utility model includes:
[0060] Chassis vehicle 1; and
[0061] At least one foldable panel box 2, wherein, in the unfolded state, the foldable panel box 2 is detachably mounted on the chassis vehicle 1 to form a container, and the foldable panel box 2 is configured so that one foldable panel box 2 (i.e., the upper panel box 2b) is detachably mounted on another foldable panel box 2 (the lower panel box 2a) (see Fig.17 ) to achieve adjustable container height.
[0062] Since the chassis 1 and the foldable panel box 2 can be separated, the two can be stored and transported separately, and the panel box can be folded, which is very convenient. At the same time, the foldable panel box 2 can usually be made of plastic injection molding, which greatly reduces the weight. In addition, the stacking quantity of the foldable panel boxes can be selected according to the transport vehicles of different specifications, so that the height of the container can be adjusted, which greatly improves the applicability and does not require the box changing operation. The height of the foldable panel box can be one or more specifications. For example, the height of the foldable panel box can be selected between 0.5 and 2m, such as 0.5m, 1m or 2m.
[0063] During installation, unfold the foldable panel box 2, and then align the foldable panel box 2 with the limiting structure on the chassis 1 and press it down to complete the fixed installation, which is very convenient. When disassembling, just release the corresponding locking mechanism. The chassis 1, the foldable panel box 2 and the fixing structure therebetween are described in detail below.
[0064] like Figure 2 and 19As shown, the chassis vehicle 1 includes a chassis 11 and four rollers 12 fixedly mounted on the bottom of the chassis 11. The rollers 12 can facilitate the movement of the foldable container 100. The rollers 12 can be universal rollers with brakes. The chassis 11 is roughly square, and its four corners are rounded. The chassis 11 can be injection molded from a lightweight material such as plastic or rubber. The chassis 11 has a certain thickness (for example, more than 5 cm) to have sufficient supporting force. There are four grooves 111 on the upper surface of the chassis 11 for accommodating the rollers 12, so that the chassis vehicles 1 can be stacked on each other (see Fig.19 ), so as to reduce the occupied space, thereby facilitating the storage and transportation of the chassis vehicle 1. Preferably, the groove 111 is an arc groove, and its depth is 50-80% of the radius of the roller 12.
[0065] Four limiting protrusions 112 are provided near the corners of the upper surface of the chassis 11, and the limiting protrusions 112 are received in the corresponding recesses at the bottom of the foldable panel box 2 when the foldable panel box 2 is installed. The limiting protrusions 112 are roughly rectangular, and their height is usually between 2 and 5 cm. A groove 1121 is provided at the inner end surface of the limiting protrusion 112, and the groove 1121 is used to cooperate with the locking tongue of the locking mechanism 3 installed on the bottom of the foldable panel box 2 (detailed description will be given below) to achieve the fixing of the foldable panel box 2 on the chassis vehicle 1. The inner end surface of the limiting protrusion 112 has a guiding slope above the groove 1121 to guide the locking tongue of the locking mechanism 3.
[0066] Four long strip-shaped limiting grooves 113 are also provided on the upper surface of the chassis 11 , and the limiting grooves 113 are used to cooperate with the limiting protrusions on the bottom of the foldable panel box 2 to further limit the foldable panel box 2 on the chassis vehicle 1 .
[0067] like Figures 2 to 18 As shown, the foldable panel box 2 includes:
[0068] A pair of first side plates (or long side plates) 21, the pair of first side plates 21 are detachably mounted on the left and right sides of the chassis vehicle 1 respectively;
[0069] A pair of door panels 22, the pair of door panels 22 are respectively hinged to the front ends of the pair of first side panels 21 and can be closed with each other; and
[0070] A pair of second side plates (or short side plates) 23 are hinged to each other. The pair of second side plates 23 are hinged to the rear ends of the pair of first side plates 21 .
[0071] When folding, first fold the pair of door panels 22 and the pair of second side panels 23 inward (such as Figure 3 Then, the pair of first side panels 21 are pressed relative to each other so that the pair of door panels 22 and the pair of second side panels 23 are completely folded between the pair of first side panels 21 (as shown in FIG. Figure 4 The thickness after folding is substantially equal to the thickness of two door panels (second side panels) plus the thickness of two first side panels, and the space occupied is very small. When unfolding, it is only necessary to pull the pair of first side panels 21 outward until the pair of door panels 22 and the pair of short side panels 23 are fully unfolded.
[0072] The first side panel 21, the door panel 22 and the second side panel 23 can be integrally injection molded from a lightweight material such as plastic or rubber. In order to further reduce weight, the first side panel 21, the door panel 22 and the second side panel 23 can adopt a hollow structure. In this embodiment, the hollow structure is a circular rectangular hole array.
[0073] In this embodiment, the foldable panel box 2 adopts a double-door structure (i.e., has a pair of door panels) to facilitate folding. It should be understood that the foldable panel box 2 can also be a single-door structure.
[0074] The locking mechanism 3 between the chassis vehicle 1 and the first side plate 21 of the foldable panel box 2 is described below. Fig.16 As shown, the locking mechanism 3 includes a lock tongue 31 and a reset member 32. The lock tongue 31 can be slidably mounted on the first side plate 21 and has an operating portion 311 and a lock tongue limiting portion 312. The operating portion 311 can operably drive the lock tongue limiting portion 312 to leave the groove 1121 on the chassis 1 to achieve unlocking. That is, the user can operate the unlocking through the operating portion 311. One end of the reset member 32 is connected to the first side plate 21, and the other end is connected to the lock tongue 31. The lock tongue limiting portion 312 enters the groove 1121 through the reset action of the reset member 32 to achieve locking. In this embodiment, the reset member 32 is a spring. When the foldable panel box 2 is installed on the chassis 1, the lock tongue 31 moves in the unlocking direction under the action of the limiting protrusion 112 on the chassis 11, and the spring 32 is compressed. When the lock tongue limiting portion 312 moves to the alignment groove 1121, under the reset action of the spring 32, the lock tongue limiting portion 312 is inserted into the groove 1121 to achieve locking. When unlocking, the lock tongue 31 is moved in the unlocking direction through the operating portion 311, so that the tongue limiting portion 312 is disengaged from the groove 1121. In this embodiment, the operating portion 311 is a rectangular recessed portion to facilitate hand operation and has a simple appearance. Preferably, an unlocking direction arrow is marked on the bottom of the operating portion 311. It should be understood that the operating portion 311 can also be other structural shapes, such as a handle or a round handle.
[0075] Preferably, the locking mechanism 3 can also be used to lock the upper and lower foldable enclosure boxes 2. That is, the upper end surface of the first side plate 21 is also provided with a limiting protrusion 211 with the same structure as the limiting protrusion 112 of the chassis vehicle 1, such as Figure 2 and 17 shown.
[0076] It should be understood that the locking mechanism between the chassis vehicle 1 and the foldable panel box 2 is not limited to the above structure. For example, a structure in which a latch and a pin hole cooperate, or a buckle structure, etc. may also be adopted.
[0077] In order to facilitate the installation between the upper and lower foldable enclosure boxes 2, the upper and lower end surfaces of the first side panel 21 and the second side panel 23 are provided with complementary limiting grooves 212, 231 and limiting protrusions 213, 232. That is, taking the first side panel 21 as an example, the limiting groove 212 and limiting protrusion 213 at the lower end of the first side panel 21 of the upper enclosure box 2 are respectively complementary to the limiting protrusion 213 and limiting groove 212 at the upper end of the lower enclosure box 2.
[0078] Further, in order to enhance the strength of the first side plate 21, a reinforcing tube 24 extending in the horizontal direction is fixedly installed below the limiting groove 212 and the limiting protrusion 213 at the upper end and above the limiting groove 212 and the limiting protrusion 213 at the lower end of the first side plate 21, such as Figure 6 The reinforcing tube 24 can be embedded in the first side panel 1 during the integral molding process, or can be fixedly installed in the reinforcing tube installation cavity 214 of the first side panel 21 during the subsequent installation process of the foldable enclosure box 2.
[0079] Preferably, the foldable panel box 2 is configured so that the folded foldable panel box 2 can be placed upright in the container 100 (i.e., placed upright in the foldable panel box 2 in the unfolded state). Fig.18 That is to say, the outer width of the folded foldable panel box 2 is smaller than the inner width of the container 100 .
[0080] In this embodiment, the hinge structure between the door panel 22 and the first side panel 21 is the same as the hinge structure between the second side panel 23 and the first side panel 21. Specifically, the hinge structure between the door panel 22 and the first side panel 21 is taken as an example for description. Figure 4 and 5 As shown, the hinge structure includes a plurality of first protrusions 215 spaced apart in the vertical direction on the end surface of the first side plate 21, a plurality of second protrusions 221 spaced apart in the vertical direction on the end surface of the L-shaped end 220 of the door plate 22, and a hinge shaft 25. The first protrusion 215 and the second protrusion 221 complement each other. That is, one first protrusion 215 is engaged between two second protrusions 221, and at the same time, one second protrusion 221 is engaged between two first protrusions 215. Both the first protrusion 215 and the second protrusion 221 have a hinge hole extending in the vertical direction, and the hinge shaft 25 is penetrated through the hinge hole, so as to realize the hinge connection between the first side plate 21 and the door plate 22. The sizes of the first protrusion 215 and the second protrusion 221 can be the same or different. The number of the first protrusion 215 and the second protrusion 221 is related to the size in the vertical direction and the height of the container 100.
[0081] Preferably, the height of the L-shaped end of the door panel 22 is substantially equal to the thickness of the first side panel 21, and the height of the first protrusion of the first side panel 21 is substantially equal to the thickness of the door panel 22 (specifically, the L-shaped end). Therefore, it can be ensured that the outer width of the folded foldable panel box 2 is smaller than the inner width of the container 100, so that the folded foldable panel box 2 can be erected and loaded into the container 100, which is convenient for storage and transportation.
[0082] In this embodiment, two upper and lower second locking mechanisms 4 are provided between a pair of door panels 22. It should be understood that the number of the second locking mechanisms 4 is not limited to the embodiment shown. Figure 7-10 As shown, the second locking mechanism 4 may include a handle seat 41, a handle 42 and a second reset member 43. The handle seat 41 and the handle 42 may also be injection molded by plastic or the like. The handle seat 41 is rotatably mounted on the end surface (e.g., the left end) of one of the door panels 22 (e.g., the right door panel 22b) away from the first side panel 21, and the handle 42 is slidably mounted on the handle seat 41 and has a first handle stopper 421, which cooperates with the first door panel stopper 222 of the other door panel 22 (e.g., the left door panel 22a) to achieve locking, and one end of the second reset member 42 abuts against the handle seat 41, and the other end abuts against the handle 42. When the door is to be opened, the locking mechanism 4 needs to be unlocked first. When unlocking, the first handle stopper 421 is disengaged from the first door panel stopper 222 by moving the handle 42 in the unlocking direction (i.e., to the left), thereby achieving unlocking. When the handle 42 is released, the handle 42 is automatically reset under the action of the reset member 43 .
[0083] In this embodiment, the second reset member 43 is an arc-shaped elastic sheet, the top of which is fixedly mounted on the handle 42 and the two ends thereof are in contact with the handle seat 41. Specifically, two first T-shaped protrusions 431 are provided at the top of the arc-shaped elastic sheet, and a second T-shaped protrusion 422 is provided on the handle 42, and the second T-shaped protrusion 422 is clamped between the two first T-shaped protrusions 431, so that the top of the arc-shaped elastic sheet (i.e., the right end) is fixed to the handle 42. The two ends (i.e., the left end) of the arc-shaped elastic sheet 43 are cylindrical, that is, the cross section thereof is circular. Preferably, a limiting recess (not shown) is provided on the handle seat 41 to limit the two ends of the arc-shaped elastic sheet 4 therein. It should be understood that the second reset member 43 can also be a spring or other forms of elastic reset members.
[0084] In this embodiment, the handle seat 41 is roughly in the shape of a "concave" character, including a square groove portion 411 in the middle and handle seat mounting portions 412 at both ends. The left side of the square groove portion 411 is open. The second reset member 43 is installed in the square groove portion 411, that is, the second T-shaped protrusion 422 of the handle 42 is located in the square groove portion 411. The end of the handle seat mounting portion 412 protrudes from the square groove portion 411, that is, it is wider than the square groove portion 411, and is provided with a first hinge hole 413. The door panel 22 is provided with a second hinge hole 223 aligned with the first hinge hole 413. The handle seat 41 is hinged to the door panel 22 by passing the hinge shaft 26 through the first hinge hole 413 and the second hinge hole 223. Therefore, the locking mechanism 4 can rotate relative to the door panel 22 (for example, 0 to 180 degrees), so that a pair of door panels 22 can be folded inward. The handle seat mounting portion 412 has a through slot 414, and a slide slot 4141 extending in the left-right direction is provided on the side wall of the through slot 414; the handle 42 includes a panel 423 and a handle mounting portion 424 extending downward from the lower surface of both sides of the panel 423 and a first handle stop portion 421, and the panel 423 covers the handle seat 41. A concave operating portion 425 is provided on the panel 423, and the size of the concave operating portion 425 is set to at least allow two fingers to be placed side by side for easy operation. It should be understood that the operating portion structure of the handle 42 is not limited to the illustrated embodiment. In this embodiment, an arrow mark for indicating the unlocking direction is also provided on the panel 423 of the handle 42, and the arrow mark is located on the left side of the concave operating portion 425. The first handle stop portion 421 protrudes from the handle mounting portion 424, that is, the lower end of the handle mounting portion 424 is lower than the lower end of the handle stop portion 421. The handle limiter 424 and the handle mounting portion 424 are both received in the through slot 414 of the handle seat mounting portion 412. A slide bar 4241 is provided on the side of the handle mounting portion 424 to be slidably engaged with the slide slot 4141. Therefore, when the handle 42 is mounted on the handle seat 41, the handle 42 can slide left and right to achieve unlocking and resetting the lock.
[0085] In this embodiment, the cross section of the first handle stopper 421 is triangular, and correspondingly, the first door panel stopper 222 is a V-shaped groove (for example, with the opening facing left). The first handle stopper 421 can slide into the first door panel stopper 222 from left to right or slide out of the first door panel stopper 222 from right to left. It should be understood that the shape and structure of the first handle stopper 421 and the first door panel stopper 222 are not limited to the illustrated embodiment.
[0086] In this embodiment, the handle 42 further has a second handle stopper 426, which cooperates with the second door panel stopper 224 on the door panel 22 (i.e., the right door panel 22b) on which the handle seat 41 is installed to limit the rotation of the locking mechanism 4 relative to the door panel 22. When the handle 42 moves in the opening direction (unlocking direction), the second handle stopper 426 is disengaged before the first handle stopper 421. The cross section of the second handle stopper 426 is substantially L-shaped, and its outer side surface is an inclined surface. The second door panel stopper 224 is located on the outer side (left side) of the second hinge hole 223 of the door panel 22.
[0087] When the foldable panel box 2 is in use (expanded), the second handle stopper 426 of the handle 42 of the second locking mechanism 4 is clamped on the second door panel stopper 224 of the door panel 22. Fig.10 When the foldable enclosure box 2 is to be folded, the handle 42 is moved to the left for a distance so that the second handle limit portion 426 is disengaged from the second door limit portion 224, such as Fig.11 As shown, the left door panel can rotate relative to the right door panel at this time; when the door panel 22 of the foldable panel box 2 is to be opened, the handle 42 is moved to the left to the bottom (i.e., the maximum distance), so that the first handle limit portion 421 is disengaged from the first door panel limit portion 222, as shown in FIG. Fig.12 As shown, the second locking mechanism 4 can then be rotated toward the right door panel and attached to the right door panel, as shown in FIG. Fig.13 At this time, the door panel 22 can be opened outward, such as Fig.14 shown.
[0088] The chassis vehicle 1 and the foldable panel box 2 of the foldable container 100 of the utility model can be disassembled and stored separately, and the foldable panel boxes 2 can be stacked, which is very convenient to use and can be applicable to various transport vehicles.
