Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of transportation equipment, in particular to a container. Background Art
[0002] As a widely used transport equipment, containers are available in various forms. For containers with foldable end frames, elastic devices are usually provided to assist the end frames in erecting. Therefore, a locking device is provided on the bottom frame to lock the end frame pivoted to the folded position to limit the end frame from turning up. During the process of the end frame pivoting to the folded position, the inner edge of the top corner piece on the corner column of the end frame presses the locking rod of the locking device, pushing the locking rod to move axially. After the end frame pivots to the folded position, the locking rod is reset and penetrates into the corner piece hole of the top corner piece, thereby limiting the end frame in the folded position.
[0003] However, the inner edge of the conventional top corner fitting, as the edge facing the inside of the box, is usually not subjected to additional treatment, so that the abutment surface of the locking rod is pressed by the right-angle edge, and the contact stress between the locking rod and the top corner fitting is large, which can easily lead to damage to the abutment surface of the locking rod or bending of the locking rod.
[0004] Therefore, a container is needed to at least partially solve the above problems. Utility Model Content

[0066] The utility model provides a container.
[0067] Now, exemplary embodiments according to the present invention will be described in more detail with reference to the accompanying drawings.
[0068] like Figure 1 As shown, a container 100 provided by a specific embodiment of the utility model includes a base frame 1 and an end frame 2. The base frame 1 includes a locking device 11, and the end frame 2 is in an upright position (such as Figure 1 The left end frame 2) and the folded position ( Figure 2 The end frame 2 on the right side of the middle is shown to be rotatably connected to the end of the base frame 1 (pivoted to a nearly folded position), and the end frame 2 includes a top corner piece 21.
[0069] Among them, Figure 2 and Figure 3 As shown, the locking device 11 includes a locking rod 111, and the locking rod 111 is provided with a first abutting surface 1111. The top corner piece 21 includes a top surface 211 (i.e., the upper surface of the top corner piece 21 when the end frame 2 is in the upright position), an inner side surface 212, and a second abutting surface 213. When the end frame 2 is in the upright position, the inner side surface 212 is the outer surface of the top corner piece 21 facing the inside of the container 100 in the length direction D1 of the container 100. The second abutting surface 213 is connected between the inner side surface 212 and the top surface 211, and the second abutting surface 213 presses against the first abutting surface 1111 during the rotation of the end frame 2 to the folded position.
[0070] It can be understood that the end frame 2 is connected to the base frame 1 by a device such as a hinge assembly, and the pivot axis of the end frame 2 is along the width direction D2 of the container 100. The upright position of the end frame 2, that is, the position of the end frame 2 in normal use, is roughly in a vertical state. The folded position of the end frame 2, that is, the storage position where the end frame 2 is pivoted to be flat on the base frame 1, is roughly in a horizontal state. In the process of the end frame 2 pivoting to the folded position, the top corner piece 21 presses the locking rod 111 of the locking device 11, and the first abutting surface 1111 of the locking rod 111 is usually an inclined surface with an angle with the axial direction of the locking rod 111. The locking rod 111 moves along its axial direction under the pressure of the top corner piece 21. After the end frame 2 continues to pivot to the folded position (locked position), the locking rod 111 locks the position of the end frame 2 by penetrating the corner piece hole of the top corner piece 21. No further restrictions are made on other specific structures of the locking device 11 here. A connecting line between the second abutting surface 213 and the box inner side surface 212 is parallel to the first abutting surface 1111 of the locking rod 111 . A connecting line between the second abutting surface 213 and the top surface 211 is parallel to the first abutting surface 1111 of the locking rod 111 .
[0071] According to the container 100 of the utility model, the second abutting surface 213 is added to the top corner fitting in the prior art, so that the first abutting surface 1111 of the lock rod 111 is pressed against a larger plane, a curved surface or an edge with a larger angle. Therefore, the contact stress of the top corner fitting 21 when the end frame 2 pivots to the lock rod 111 can be reduced, and the problem of damage to the lock rod abutting surface or bending of the lock rod caused by excessive contact stress caused by the right-angle edge of the top corner fitting pressing against the inclined surface of the lock rod in the prior art can be avoided.
[0072] It should be noted that the directional terms used for the various components and parts of the container 100 described in the present invention are relative to the container 100 placed horizontally and in an upright state, at which time the chassis 1 of the container 100 is placed horizontally.
[0073] Optionally, the second abutting surface 213 is set to be a plane, and the second abutting surface 213 includes a first edge 2131 and a second edge 2132. The first edge 2131 is connected to the inner side surface 212 of the box, that is, the first edge 2131 is the connecting line between the second abutting surface 213 and the inner side surface 212 of the box. The second edge 2132 is connected to the top surface 211, that is, the second edge 2132 is the connecting line between the second abutting surface 213 and the top surface 211. At least one of the first edge 2131 and the second edge 2132 presses against the first abutting surface 1111 during the rotation of the end frame 2 to the folded position. For example, when the end frame 2 rotates to the point where the top corner piece 21 just contacts the locking rod 111, the first edge 2131 presses against the first abutting surface 1111, and as the end frame 2 continues to rotate, the second edge 2132 presses against the first abutting surface 1111.
[0074] It can be understood that the angles corresponding to the first edge 2131 and the second edge 2132 are both greater than 90°, that is, the angle formed by the second abutting surface 213 of the top corner piece 21 and the inner side surface 212 of the box and the angle formed by the second abutting surface 213 of the top corner piece 21 and the top surface 211 are both greater than 90°. The first edge 2131 and the second edge 2132 are parallel to the first abutting surface 1111 of the locking rod 111.
[0075] Preferably, when the end frame 2 rotates until the second abutting surface 213 contacts the first abutting surface 1111, the second abutting surface 213 is parallel to the first abutting surface 1111. That is, when the end frame 2 rotates until the second abutting surface 213 just contacts the first abutting surface 1111, the first abutting surface 1111 and the second abutting surface 213 are in contact, and at this time, the first abutting surface 1111 and the second abutting surface 213 are in surface contact.
[0076] It can be understood that, as the end frame 2 continues to rotate, the first abutting surface 1111 and the second abutting surface 213 are no longer in contact with each other, and at the same time, the second edge 2132 of the second abutting surface 213 presses against the first abutting surface 1111 .
[0077] Preferably, the distance from the first edge 2131 to the plane where the top surface 211 is located is set to be greater than or equal to 3 mm and less than 15 mm. The distance from the second edge 2132 to the plane where the box inner side surface 212 is located is set to be greater than or equal to 3 mm and less than 15 mm.
[0078] Preferably, the second abutting surface 213 is set as a curved surface. Further preferably, the radius of the curved surface is set to be greater than or equal to 3 mm and less than 15 mm. It can be understood that when the second abutting surface 213 is a curved surface, the contact stress between the second abutting surface 213 and the first abutting surface 1111 is small, thereby avoiding excessive contact stress that causes damage to the abutting surface of the locking rod or bending of the locking rod.
[0079] Preferably, the base frame 1 further comprises a buffer device, which abuts against the end frame 2 during at least a portion of the rotation stroke of the end frame 2 close to the base frame 1. The buffer device can provide buffering during the process of the end frame 2 pivoting toward the folded position, thereby reducing the impact force of the top corner piece 21 on the locking rod 111, that is, reducing the force of the second abutting surface 213 pressing against the first abutting surface 1111, thereby avoiding damage to the abutting surface of the locking rod or bending of the locking rod.
[0080] Specifically, Figure 4As shown, the buffer device includes a support plate 13, a stopper assembly 14 and a leaf spring 15. The support plate 13 is located on the outer side of the bottom side beam 12 of the chassis 1 and is fixed to the bottom side beam 12. The upper surface of the support plate 13 is an arc surface. The leaf spring 15 is at least partially supported on the upper surface of the support plate 13, and includes a first end 151 and a second end 152 for abutting the end frame 2. The stopper assembly 14 is fixed to the outer side of the bottom side beam 12, and the position of the first end 151 is jointly defined by the stopper assembly 14 and the upper surface of the support plate 13.
[0081] Preferably, if Figure 4 As shown, the limiting assembly 14 includes a fixing plate 141, a connecting plate 142 and a positioning shaft 143. The fixing plate 141 is fixed to the outer side of the bottom side beam 12, and the connecting plate 142 is fixed to the fixing plate 141 and extends outward. The first end 151 of the leaf spring 15 has a positioning hole 1511, one end of the positioning shaft 143 penetrates the positioning hole 1511, and the other end is fixed to the connecting plate 142. Alternatively, one end of the positioning shaft 143 penetrates the positioning hole 1511, and the other end is penetrated in the fixing sleeve 1421 on the connecting plate 142. Thus, the first end of the leaf spring 15 is limited to a specific position between the upper surface of the support plate 13 and the connecting plate 142 of the limiting assembly 14.
[0082] Preferably, the buffer device also includes a clip 16, which is fixed to the support plate 13 and is located in the middle of the leaf spring 15, and is used to limit the leaf spring 15 to prevent the leaf spring 15 from detaching from the upper surface of the support plate 13 along the width direction D2 of the container 100, or the clip 16 can also be configured to limit the upward movement distance of the leaf spring 15.
[0083] Preferably, the end frame 2 is provided with a pressing shaft 23 for abutting against the buffer device, specifically, the pressing shaft 23 abuts against the second end 152 of the leaf spring 15. The pressing shaft 23 is fixed to the corner column 22 of the end frame 2 through a bracket 24. The axial direction of the pressing shaft 23 is preferably parallel to the upper surface of the second end 152 of the leaf spring 15.
