[0095] It should be noted that the terms "upper", "lower", "front", "back", "left", "right", "inside", "outside" and similar expressions used in the present invention are for illustrative purposes only and are not limiting.

[0096] The invention discloses a bracket supporting device and a container.

[0097] Now, exemplary embodiments according to the present invention will be described in more detail with reference to the accompanying drawings.

[0098] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, in a preferred embodiment, a bracket support device 105b includes: a first support rod 106a, a second support rod 106b, a third support rod 106c and a locking device 107;

[0099] The first end of the first support rod 106a is used to be hinged to the lane bracket 104b of the container 100, and the upper end of the first support rod 106a shown in the figure is its first end;

[0100] The first end of the second support rod 106b is used to be hinged to the bottom frame assembly 101 of the container 100, and the lower end of the second support rod 106b shown in the figure is its first end;

[0101] The first end of the third support rod 106c is used to be hinged to the bottom frame assembly 101 of the container 100, and the lower end of the third support rod 106c shown in the figure is its first end;

[0102] The locking device 107 is arranged on the third support rod 106c and can be moved and locked on the third support rod 106c. The second end of the first support rod 106a is hinged to the locking device 107, and the second end of the second support rod 106b is hinged to the locking device 107. The first support rod 106a and the second support rod 106b can be folded and unfolded relative to each other.

[0103] like Figure 4 , Figure 5 As shown, when the lane bracket 104b needs to be used, the bracket support device 105b is unfolded, and the first support rod 106a, the second support rod 106b, and the third support rod 106c are a star-shaped structure. At this time, the locking device 107 is locked on the third support rod 106c to maintain the relative position relationship of the first support rod 106a, the second support rod 106b, and the third support rod 106c.

[0104] like Figure 6 As shown, when the lane bracket 104b is not needed, the bracket support device 105b is folded. At this time, the locking device 107 can be moved on the third support rod 106c to fold the first support rod 106a and the second support rod 106b relative to each other until the overall height of the bracket support device 105b is reduced to approximately equal to the height of the first support rod 106a and the second support rod 106b superimposed on each other.

[0105] The bracket support device 105b in this embodiment, by setting three support rods, shortens the length of each support rod compared to setting one support rod in the prior art, so that the operating angle of the support rod and the moving stroke of the locking device 107 are reduced, saving the space required for installation in the container 100 and reducing the impact of the bracket support device 105b on the loading space of the container 100.

[0106] In one embodiment, if Figure 4 , Figure 5 As shown, the second end of the first support rod 106a and the second end of the second support rod 106b are both provided with obtuse-angle bending structures, and when the first support rod 106a and the second support rod 106b are folded relative to each other, the two obtuse-angle bending structures are arranged relative to each other, so that the first support rod 106a and the second support rod 106b can be folded in an overlapping manner.

[0107] Through this arrangement, the first support rod 106a and the second support rod 106b can avoid each other when folded relative to each other, thereby reducing the overall height of the folded bracket support device 105b, reducing the impact of the folded bracket support device 105b on the height of the container 100, and facilitating the storage and transportation of the folded container 100.

[0108] In one embodiment of the obtuse angle bending structure, Figure 4 , Figure 5 , Figure 6 As shown, the second ear 110 is provided with an obtuse-angle bending structure, and when the first support rod 106a and the second support rod 106b are folded relative to each other, the obtuse-angle bending structures of the two second ears 110 are arranged relative to each other, so that the first support rod 106a and the second support rod 106b can be folded in an overlapping manner.

[0109] In the figure, the obtuse angle of the second ear 110 of the first support rod 106a is greater than the obtuse angle of the second ear 110 of the second support rod 106b. Through this arrangement, the first support rod 106a and the second support rod 106b can avoid each other when folded relative to each other, and finally can fit together up and down, thereby reducing the overall height of the bracket support device 105b to approximately equal to the height of the first support rod 106a and the second support rod 106b superimposed up and down.

[0110] In one embodiment, if Figure 4 , Figure 5 As shown, the first end of the first support rod 106a and the first end of the second support rod 106b are both provided with a first ear 111, and the second end of the first support rod 106a and the second end of the second support rod 106b are both provided with a second ear 110, and the first ear 111 and the second ear 110 include one ear plate or two ear plates, and the distance between the two ear plates is greater than the thickness of one ear plate.

[0111] The first support rod 106a and the second support rod 106b may include Figure 8 The support rod body 109 shown is a rectangular tube or a round tube. The first end of the support rod body 109 is provided with a groove portion 192, and the first end is suitable for mounting an ear plate. The second end of the support rod body 109 is provided with a protrusion 191, and the second end is suitable for mounting two ear plates. The ear plate has an appropriate thickness, a high structural strength, and is not easily deformed during use. A hinge hole is provided on it for connection. The ear plate and the support rod body 109 can be fixedly connected by welding.

[0112] The third support rod 106c may include Fig. 9 The support rod body 113 shown is a rectangular tube or a round tube, and a hinge hole 302 is provided at the first end for hinge connection with the bottom frame assembly 101 of the container 100 .

[0113] In one embodiment, if Figure 4 , Figure 5As shown, the second ear 110 of the first support rod 106a and the second ear 110 of the second support rod 106b include different numbers of ear plates, so that the second ear 110 including one ear plate can be inserted into the second ear 110 including two ear plates. In the figure, the second ear 110 of the first support rod 106a includes two ear plates, and the spacing between the two ear plates is greater than the thickness of one ear plate. The second ear 110 of the second support rod 106b includes one ear plate, and the second ear 110 of the second support rod 106b can be inserted into the second ear 110 of the first support rod 106a. Through this arrangement, the first support rod 106a and the second support rod 106b can form an overlapping relationship in the height direction, and will not hinder each other when rotating.

[0114] In one embodiment, if Figure 7 As shown, the first support rod 106a and the second support rod 106b are staggered left and right, so that the first support rod 106a and the second support rod 106b can be folded in a left-right overlapping manner.

[0115] In the figure, the second ear 110 of the first support rod 106a and the second ear 110 of the second support rod 106b include the same number of ear plates, both include one ear plate, and may also include two ear plates. The two second ears 110 no longer have an entry relationship, but are staggered left and right. The first support rod 106a and the second support rod 106b do not hinder each other when they are folded relative to each other, and can eventually fit together left and right, reducing the overall height of the bracket support device 105b to approximately equal to the height of the first support rod 106a or the second support rod 106b.

[0116] In one embodiment, if Figure 4 , Figure 5 , Fig.10 As shown, the locking device 107 includes: a sliding sleeve 112, a rotating shaft 116 and at least one positioning latch 115;

[0117] The sliding sleeve 112 is sleeved on the third support rod 106c. The sliding sleeve 112 is a rectangular tube or a round tube. The sliding sleeve 112 is provided with at least one second through hole perpendicular to the moving direction. The third support rod 106c is correspondingly provided with a plurality of first through holes 301. The sliding sleeve 112 moves on the third support rod 106c so that the second through holes can be aligned with the first through holes 301 at different positions.

[0118] The rotating shaft 116 is disposed on the first side of the sliding sleeve 112, and the second end of the first support rod 106a and the second end of the second support rod 106b are both hinged to the rotating shaft 116;

[0119] The positioning pin 115 can be inserted into the first through hole 301 and the second through hole to lock the sliding sleeve 112 on the third support rod 106c.

[0120] A plurality of positioning pins 115 may be provided to increase the connection strength between the sliding sleeve 112 and the third support rod 106 c and improve the stability of the locked state, so that the lane bracket 104 b can carry a vehicle with a heavier weight.

[0121] During the relative unfolding and folding of the first support rod 106a and the second support rod 106b, the sliding sleeve 112 is in a movable state on the third support rod 106c. After the first support rod 106a and the second support rod 106b are unfolded, the sliding sleeve 112 is in a locked state on the third support rod 106c and cannot move anymore, thereby maintaining the unfolded state of the first support rod 106a and the second support rod 106b.

[0122] In one embodiment, if Fig.10 As shown, the sliding sleeve 112 further includes: a sliding sleeve body 119 and a reinforcing plate 118;

[0123] The sleeve body 119 is a circumferentially closed tubular structure or a circumferentially semi-closed tubular structure; the sleeve body 119 in the figure is a circumferentially semi-closed tubular structure with a U-shaped cross section;

[0124] The reinforcing plate 118 is disposed on one side of the sliding sleeve body 119 close to the rotating shaft 116 . The rotating shaft 116 is fixedly connected to the reinforcing plate 118 . The thickness of the reinforcing plate 118 is greater than the thickness of the sliding sleeve body 119 .

[0125] The reinforcing plate 118 and the sleeve body 119 can be fixedly connected by welding, and the rotating shaft 116 and the reinforcing plate 118 can be fixedly connected by welding. The reinforcing plate 118 is arranged on the side where the sleeve 112 is mainly subjected to force. Through this arrangement, the structural strength of the sleeve 112 can be improved, and it is not easy to deform during use, and the movable relationship with the third support rod 106c can be maintained, so that the sleeve 112 can be prevented from failing when subjected to large shear force and torsional stress.

[0126] In order to improve the structural strength of the rotating shaft 116 and prevent the rotating shaft 116 from being deformed by force, a reinforcing rib 117 can be provided at the connection between the rotating shaft 116 and the reinforcing plate 118 to improve the connection strength between the rotating shaft 116 and the reinforcing plate 118, thereby keeping the rotating shaft 116 from being skewed during use and maintaining the structural relationship between the first support rod 106a, the second support rod 106b and the locking device 107.

[0127] In one embodiment, if Fig.10 , Fig.11 As shown, the locking device 107 further includes: a latch holder 120;

[0128] The latch retaining seat 120 is arranged on the second side of the sliding sleeve 112. The latch retaining seat 120 is L-shaped and includes a base plate 201 and a side plate 202. The base plate 201 is fixedly connected to the sliding sleeve 112 and can be fixedly connected by welding. At least one positioning hole 203 is arranged on the side plate 202. The positioning pin 115 passes through the sliding sleeve 112 and the third support rod 106c and is connected to the positioning hole 203, which can improve the stability of the positioning pin 115 on the sliding sleeve 112. The number of positioning holes 203 is the same as the number of positioning pins 115.

[0129] In one embodiment, if Figure 4 , Figure 5 , Fig.12 As shown, the positioning latch 115 includes: a cylindrical pin 121 and a plug-in handle 122;

[0130] The first end of the cylindrical pin 121 is configured as a plug-in end, and the plug-in end is configured as a cone, so as to facilitate insertion into the second through hole of the sliding sleeve 112 and the first through hole 301 of the third support rod 106c, and also facilitate connection with the positioning hole 203 of the plug holder 120;

[0131] The first end of the plug-in handle 122 is fixedly connected to the second end of the cylindrical pin 121, and can be fixedly connected by welding. The cylindrical pin 121 and the sliding sleeve 112 are plugged in or separated by the plug-in handle 122. The second end of the plug-in handle 122 is provided with a stop structure, and the stop structure is L-shaped. After the cylindrical pin 121 and the sliding sleeve 112 are plugged in, the third support rod 106c is connected through the stop structure to prevent the cylindrical pin 121 from being separated from the sliding sleeve 112.

[0132] The plug handle 122 is provided with two bending structures, which are not in the same plane, so that the third support rod 106c can be connected when the cylindrical pin 121 is plugged into the sliding sleeve 112. When the positioning latch 115 needs to be removed, the plug handle 122 only needs to be rotated in the opposite direction to release the connection with the third support rod 106c and separate the cylindrical pin 121 from the sliding sleeve 112.

[0133] In one embodiment, if Fig.11 , Fig.12 As shown, at least one insertion hole 204 is provided on the bottom plate 201, and at least one slot 205 is provided on the side plate 202. The idle positioning pin 115 is installed on the pin retaining seat 120, and the cylindrical pin 121 of the positioning pin 115 is inserted into the insertion hole 204, and the handle of the positioning pin 115 is inserted into the slot 205. This can prevent the positioning pin 115 from being lost after disassembly, and also facilitates the rapid connection between the positioning pin 115 and the sliding sleeve 112 when the sliding sleeve 112 and the third support rod 106c need to be locked, thereby improving the deployment efficiency of the bracket support device 105b.

[0134] In one embodiment, if Figure 4 , Figure 5 , Fig. 9 As shown, a limiting rod 114 is disposed at the second end of the third support rod 106c, and the limiting rod 114 can block the movement of the sliding sleeve 112 to prevent the sliding sleeve 112 from detaching from the second end of the third support rod 106c.

[0135] The limiting rod 114 can be connected and fixed to the third support rod 106c along the width direction of the third support rod 106c by a bolt. Because the first end of the third support rod 106c is hinged to the bottom frame assembly 101 of the container 100, the sliding sleeve 112 cannot be separated from the first end of the third support rod 106c, so it is only necessary to set the limiting rod 114 at the second end of the third support rod 106c.

[0136] In one embodiment, if Fig.13 As shown, the positioning latch 115 can be replaced by a positioning latch 136 with a relatively simple structure having a latch handle and a locking plate, which simplifies the structure and reduces the manufacturing cost, or other latches that can meet the limiting function can be used as replacements.

[0137] In one embodiment, the locking device 107 may also adopt other structural forms, such as Fig.14 As shown, the locking device 107 comprises:

[0138] A guide seat 132, which is disposed at the second end of the third support rod 106c and is coaxial with the third support rod 106c; the guide seat 132 and the third support rod 106c may be fixedly connected by welding;

[0139] An adjusting screw 133, the adjusting screw 133 is disposed in the guide seat 132 and can rotate around its own axis in the guide seat 132;

[0140] Support seats 134, which are disposed at both ends of the guide seat 132, limit the adjusting screw 133 in the guide seat 132, and can support the adjusting screw 133 to rotate;

[0141] The sliding sleeve 135 is provided with an internal thread, the sliding sleeve 135 is threadedly connected to the adjusting screw 133, and the sliding sleeve 135 is restricted by the guide seat 132 and cannot rotate in the guide seat 132. When the adjusting screw 133 rotates, the sliding sleeve 135 moves in the guide seat 132 along the axis of the adjusting screw 133;

[0142] The rotating shaft 116 (not shown in the figure) is arranged on the first side of the sliding sleeve 135, and the second end of the first support rod 106a and the second end of the second support rod 106b are both hinged to the rotating shaft 116. A slide groove is arranged on the left or right side of the guide seat 132, and the rotating shaft 116 can extend from the slide groove and be hinged to the first support rod 106a and the second support rod 106b. When the sliding sleeve 135 moves in the guide seat 132, the rotating shaft 116 moves along the slide groove.

[0143] The adjusting screw 133 rotates clockwise or counterclockwise and can move in different directions in the guide seat 132. When it moves away from the third support rod 106c, the first support rod 106a and the second support rod 106b can be relatively unfolded; when it moves toward the direction close to the third support rod 106c, the first support rod 106a and the second support rod 106b can be relatively folded.

[0144] In one embodiment, if Fig.14 As shown, the locking device 107 also includes:

[0145] The handle 131 is fixedly connected to the first end of the adjusting screw 133, and the adjusting screw 133 is rotated by rotating the handle 131. The handle 131 is roughly Z-shaped, and the adjusting screw 133 can be rotated by operating the handle 131, so that the adjusting screw 133 rotates in a clockwise direction or a counterclockwise direction.

[0146] Because the lane bracket 104b is provided with two support plates for supporting vehicle wheels, both support plates need to be supported, so two sets of bracket support devices 105b need to be provided in the container 100 to support the lane bracket 104b.

[0147] In one embodiment, if Figure 1 , Figure 3 As shown, two groups of bracket support devices 105b are symmetrically arranged in the container 100, and a transverse connecting rod 108 is arranged between the two groups of bracket support devices 105b. The two ends of the transverse connecting rod 108 are respectively fixedly connected to the second support rods 106b of the two groups of bracket support devices 105b, and the connection can be fixed by welding. By arranging the transverse connecting rod 108, the two groups of bracket support devices 105b can be unfolded and folded synchronously, and the support of the lane bracket 104b is more stable, which prevents the lane bracket 104b from tilting during the lifting process.

[0148] The two ends of the transverse connecting rod 108 can also be fixedly connected to the first supporting rod 106a of the two sets of bracket supporting devices 105b, or fixedly connected to the third supporting rod 106c, or fixedly connected to the locking device 107, for example, fixedly connected to the rotating shaft or the sliding sleeve 112 in the locking device 107. These connection structures can achieve the effect of improving the support of the two sets of bracket supporting devices 105b to the lane bracket 104b more stably. It should be noted that if one of the first supporting rod 106a or the second supporting rod 106b is located on the relatively outer side, it is not suitable to connect the transverse connecting rod 108, because there may be mechanism interference when the bracket supporting device 105b is folded, and the transverse connecting rod 108 is only suitable for connecting with the first supporting rod 106a or the second supporting rod 106b located on the relatively inner side. Because the third supporting rod 106c and the locking device 107 have parts that do not overlap with other components, there is no mechanism interference problem when the transverse connecting rod 108 is connected to the bracket supporting device 105b when it is folded.

[0149] like Figure 1 , Figure 2 , Fig.18 As shown, an embodiment of the present invention further provides a container 100, comprising: a bracket support device 105b according to any one of the above embodiments.

[0150] During the raising process of the lane bracket 104b, the bracket support device 105b is unfolded accordingly. The raised state of the lane bracket 104b is as follows: Fig.15 As shown, the bracket support device 105b is in an unfolded state at this time. During the descending process of the lane bracket 104b, the bracket support device 105b is folded accordingly. The descending state of the lane bracket 104b is as shown in FIG. Fig.16 As shown, the bracket support device 105b is in a folded state at this time.

[0151] It should be noted that the bracket support device 105 b can be used alone in the container 100 , or can be used together with the existing bracket support device 105 a in the container 100 . Figure 1 The middle container 100 is provided with three sets of lane brackets 104b, and the second ends of the three sets of lane brackets 104b are all provided with two sets of bracket support devices 105b; Fig.18 The middle container 100 is provided with three sets of lane brackets 104b, the second end of the lane bracket 104b near the front end uses two sets of bracket support devices 105b, and the second end of the lane bracket 104a located in the middle and near the rear end uses two sets of existing bracket support devices 105a.

By providing the first ear seat 123, it is convenient to provide a connection hole and install a pin shaft, so that the first end of the first support rod 106a is hinged to the lane bracket 104b;

[0155] When the second end of the lane bracket 104b is lifted upward, the first support rod 106a and the second support rod 106b of the bracket support device 105b can be relatively unfolded, and when the second end of the lane bracket 104b is dropped downward, the first support rod 106a and the second support rod 106b of the bracket support device 105b can be relatively folded.

[0156] In one embodiment, if Figure 1 , Figure 2 , Fig.18 As shown, the chassis assembly 101 includes: two bottom side beams 101b and a plurality of bottom cross beams 101a;

[0157] The bottom side beams 101b are arranged on both sides of the bottom frame assembly 101 along the length direction of the container 100, and the width of the lane bracket 104b is not greater than the distance between the two bottom side beams 101b;

[0158] The bottom cross beam 101a is arranged between the two bottom side beams 101b along the width direction of the container 100, and the second support rod 106b and the third support rod 106c of the bracket support device 105b are respectively hinged to the bottom cross beam 101a, and the hinge position is located between the two bottom side beams 101b.

By providing the second ear seat 124, it is convenient to set the connection hole and install the pin shaft, so as to realize the hinge connection between the first end of the second support rod 106b and the bottom cross beam 101a; by providing the third ear seat 125, it is convenient to set the connection hole and install the pin shaft, so as to realize the hinge connection between the first end of the third support rod 106c and the bottom cross beam 101a.

[0160] In one embodiment, if Figure 1 , Fig.18 As shown, a pull ring 127 is provided at the top of the second end of the lane bracket 104b, and the second end of the lane bracket 104b is raised and lowered by operating the pull ring 127. The pull ring 127 and the lane bracket 104b can be fixed by welding.

[0161] In one embodiment, if Figure 1 , Fig.15 , Fig.18 As shown, a movable block 128 is also provided on the lane bracket 104b, and the block 128 is used to block the wheels of the vehicle. According to different loaded vehicles, the position of the block 128 on the top of the lane bracket 104b can be adjusted to accommodate vehicles of different lengths.

[0162] In one embodiment, if Fig.15 , Fig.16 As shown, a support block 126 is also provided on the bottom end beam 101c. The support block 126 is arranged on one side of the bottom end beam 101c close to the lane bracket 104b. The top of the support block 126 is lower than the top of the bottom end beam 101c to form a limiting step. When the lane bracket 104b needs to be laid flat for unloading, its front lower end portion can be abutted against the bottom end beam 101c and the support block 126 to achieve horizontal limiting.

[0163] In one embodiment, if Fig.17As shown, the bottom end beam 101c is also provided with a first lock assembly 129, which is used to lock the lane bracket 104b after landing to prevent the lane bracket 104b from shaking at will after landing.
