Description

Technical Field

[0001] This utility model relates to the field of transportation and storage equipment technology, specifically to a container. Background Technology

[0002] A shipping container typically consists of a pair of side walls, doors, a front end, a top plate, and a bottom frame. The front end includes end beams, and the doors include sills. During the stacking and placement of containers at docks and yards, the thin-plate end beams and sills are easily deformed and damaged upon impact. Therefore, anti-collision grooves are installed at the end beams and sills to provide protection.

[0003] However, the bottom surface (bottom of the groove) of existing anti-collision grooves is flat, resulting in poor cushioning effect against collisions. In addition, the connection surface between the outer surface of the anti-collision groove and the sill structure is at a perpendicular angle, which also makes automated welding processes difficult. At the same time, the door end is a place where goods are frequently loaded and unloaded, and the existing anti-collision groove structure is not strong enough, causing the sill structure at the door end to be prone to deformation, which in turn leads to easy damage to the floor at the door end, resulting in high maintenance and operating costs.

[0004] Therefore, a container is needed to at least partially solve the above problems. Utility Model Content

[0005] The utility model description section introduces a series of simplified concepts, which will be further explained in detail in the detailed description section. This utility model description section is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0006] To at least partially solve the above problems, this utility model provides a container, the container comprising:

[0007] Corner fittings;

[0008] An end member extending along the width of the container, the end member connecting to the bottom corner brackets at both ends, and having a notch at the lower edge of the portion connecting to the bottom corner brackets; the end member being a bottom beam or a sill.

[0009] A bumper groove, opening downwards at the notch and connecting to the end member and the bottom corner member, the groove width being maximum at the opening, the bumper groove having an inner surface facing inwards, the inner surface being smooth, the inner surface comprising a first inner side surface, an inner top surface, and a second inner side surface that are smoothly connected in sequence.

[0010] Wherein, the first inner surface and the second inner surface are curved surfaces; or

[0011] The first inner side and the second inner side each include a first planar portion and a first curved surface portion connected to each other. The first planar portion is located below the first curved surface portion. In the height direction of the container, the size of the first curved surface portion is larger than the size of the first planar portion.

[0012] According to the container of this utility model, the inner surface of the anti-collision groove is smooth, and the first inner side and the second inner side are curved surfaces. Alternatively, the first curved surface portion connects the first flat portion and the inner top surface, and the second curved surface portion connects the second flat portion and the inner top surface. Furthermore, in the height direction of the container, the dimension of the first curved surface portion is larger than the dimension of the first flat portion. This design, on the one hand, increases the probability that the force point on the side of the anti-collision groove is on the arc portion when it is impacted, thereby reducing the impact force in the height direction of the container, buffering deformation, and guiding the impact direction. On the other hand, the large radius of the curved surface connecting the inner bottom surface and the side surface of the anti-collision groove results in higher structural strength and stronger load-bearing capacity. Therefore, the anti-collision groove of this solution can improve the deformation resistance of the bottom beam and / or sill, reducing the probability of damage to the floor near the end of the container.

[0013] Optionally, both the first inner surface and the second inner surface are circular arcs in the cross-section of the anti-collision groove.

[0014] Optionally, the first inner side and the second inner side each include a first planar portion and a first curved surface portion connected to each other, wherein the first curved surface portion is an arc in the cross-section of the anti-collision groove.

[0015] Optionally, the inner top surface is a plane.

[0016] Optionally, the inner surface is an arc in the cross-section of the anti-collision groove, or

[0017] The first curved portion of the first inner side surface, the inner top surface, and the first curved portion of the second inner side surface are connected in an arc in the cross-section of the anti-collision groove.

[0018] Optionally, the radius of the arc is greater than 12 mm.

[0019] Optionally, the anti-collision groove has an outer surface facing outward, the outer surface including a first outer side surface, an outer top surface and a second outer side surface connected in sequence, the first outer side surface being connected to the bottom corner piece, the outer top surface being connected to the end member, and the second outer side surface being connected to the end member, wherein the outer top surface is a plane.

[0020] Optionally, the first outer surface is a plane.

[0021] Optionally, the second outer surface is a plane.

[0022] Optionally, the second outer surface is a smooth curved surface.

[0023] Optionally, the second outer surface includes a smoothly connected second planar portion and a second curved portion, the second planar portion being connected to the bottom corner piece, the second curved portion being connected between the second planar portion and the outer top surface, and the second curved portion being divided into a smooth curved surface.

[0024] Optionally, at least one of the first outer surface and the second outer surface is provided with a recess.

[0025] Optionally, the anti-collision groove has an outer surface facing outward, the outer surface including a first outer side surface, an outer top surface and a second outer side surface connected in sequence, the first outer side surface, the outer top surface and the second outer side surface are all connected to the end member;

[0026] The outer top surface is a smooth curved surface.

[0027] Optionally, the first outer surface, the outer top surface, and the second outer surface are connected in an arc in the cross-section of the anti-collision groove.

[0028] According to this invention, the inner surface of the anti-collision groove of the container is smooth, and all or most of the inner side surface is curved, with a radius greater than 12mm. Therefore, the inner top surface has no flat surface, or, without changing the overall dimensions of the existing anti-collision groove, the flatness of the inner top surface in the width direction of the container can be reduced by more than 24mm compared to existing anti-collision grooves. When the anti-collision groove is impacted, the probability of the force point falling on the curved surface is higher, thereby reducing the impact force in the height direction of the container, buffering deformation, and guiding the impact direction. The large radius of the curved surface connecting the inner bottom surface and the side surface of the anti-collision groove results in higher structural strength and stronger load-bearing capacity. Furthermore, the anti-collision groove of this solution can improve the deformation resistance of the bottom beam and / or sill, reducing the probability of floor damage near the container ends. In addition, the outer side surface of the anti-collision groove, where it connects to the bottom beam and / or sill, has a smooth curved surface, improving the process performance of automatic welding of the anti-collision groove.

[0058] This utility model provides a container to solve the problems of poor structural strength, inadequate buffering effect on collisions, and reduced welding efficiency of existing container anti-collision grooves.

[0059] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings.

[0060] like Figure 1 As shown, this utility model provides a container 100, which includes an end member 10, a bottom corner piece 20, and a crash barrier 30. The end member 10 extends along the width direction D1 of the container 100. Both ends of the end member 10 are respectively connected to a bottom corner piece 20, and a notch is provided at the lower edge of the portion connected to the bottom corner piece 20. That is, the bottom corner piece 20 and the end member 10 are on opposite sides of the notch, and the end member 10 is on the upper side of the notch.

[0061] The anti-collision groove 30 opens downward at the notch and connects to the end member 10 and the bottom corner member 20, for protecting the end structure of the container 100 at the connection with the bottom corner member 20. The container 100 is provided with the anti-collision groove 30 at the connection between the end member 10 and at least one bottom corner member 20.

[0062] End member 10 is a bottom beam or sill. For example, if container 100 is configured to open at both ends, end member 10 is a sill. For example, if container 100 is configured to open at one end and close at the other end, end member 10 is a sill at the open end and a bottom beam at the closed end. For example, if container 100 is configured to open at one end and close at the other end, end member 10 is only a sill at the open end.

[0063] like Figure 2 As shown, the anti-collision groove 30 includes a first side wall 30a, a top wall 30b, and a second side wall 30c. In the width direction of the container 100, the first side wall 30a and the second side wall 30c are respectively connected to both sides of the top wall 30b to form a shape together with the top wall 30b along the length direction of the container 100. Figure 1 A groove extending perpendicular to the plane of the paper. The two sidewalls of the anti-collision groove 30 are arranged opposite each other and connected to the bottom corner piece 20 and the end member 10 respectively. It can be understood that the anti-collision groove 30 opens downward when the container 100 is in the normal placement state, and the bottom of the groove is the top wall 30b of the anti-collision groove 30.

[0064] The terms "upper," "lower," and "top" used in this article refer to the container 100 in its normal placement state (i.e., the anti-collision groove opening is facing downwards).

[0065] like Figures 2 to 8 As shown, the anti-collision groove 30 has an inner surface facing inwards, which is smooth, meaning the curvature of the inner surface changes continuously. The inner surface includes a first inner side surface 31, an inner top surface 32, and a second inner side surface 33 that are smoothly connected in sequence. The first inner side surface 31 is the surface of the first sidewall 30a facing inwards; the inner top surface 32 is the surface of the top wall 30b facing inwards; and the second inner side surface 33 is the surface of the second sidewall 30c facing inwards.

[0066] The first inner surface 31 and the second inner surface 33 are curved surfaces; in other words, the inner surfaces are curved at the first sidewall 30a and the second sidewall 30c. The width of the anti-collision groove 30 is greatest at the groove opening, meaning that the first sidewall 30a and the second sidewall 30c curve towards each other from bottom to top (i.e., from the groove opening to the groove bottom). The groove width is the distance between the first inner surface 31 and the second inner surface 33 in the width direction D1 of the container 100. Therefore, when an external impacting object enters the anti-collision groove from the groove opening, the first inner surface 31 or the second inner surface 33 can guide the impact direction, reducing the impact force in the height direction. The transition of the anti-collision groove 30 from the sidewall to the top wall is gentle, resulting in higher structural strength and stronger pressure resistance. This, in turn, can improve the deformation resistance of the bottom beam and / or sill, reducing the probability of floor damage near the container ends.

[0067] Alternatively, the first inner surface 31 and the second inner surface 33 each include a connected first planar portion 31a / 33a and a first curved surface portion 31b / 33b. The first planar portion 31a / 33a is a plane, and the first curved surface portion 31b / 33b is a curved surface with non-zero curvature. Specifically, the first inner surface 31 includes the connected first planar portion 31a and the first curved surface portion 31b; the second inner surface 33 includes the connected first planar portion 33a and the first curved surface portion 33b. The first planar portion 31a is located below the first curved surface portion 31b, and in the height direction D2 of the container, the size of the first curved surface portion 31b is larger than the size of the first planar portion 31a. The second planar portion 33a is located below the second curved surface portion 33b, and in the height direction D2 of the container, the size of the second curved surface portion 33b is larger than the size of the second planar portion 33a.

[0068] Therefore, the first curved surface portion 31b connects the first flat surface portion 31a and the inner top surface 32, and the first curved surface portion 33b connects the first flat surface portion 33a and the inner top surface 32. The first flat surface portion 31a and the inner top surface 32, as well as the first flat surface portion 33a and the inner top surface 32, are connected by curved surfaces of larger dimensions, and the anti-collision groove 30 transitions gently from the side wall to the top wall.

[0069] It should be noted that the width of the anti-collision groove 30 is the largest at the groove opening, and it is possible that the first plane portion 31a / 33a extends along the height direction D2 of the container.

[0070] According to this invention, when a colliding object enters the anti-collision groove and impacts the groove wall, the transition from the side wall to the top wall of the groove is gentle, and the inner surface can disperse the impact force, buffer deformation, and guide the impact direction. Therefore, the anti-collision groove provides better protection for the bottom beam and / or sill at the connection with the bottom corner fittings, and further prevents damage to the floor near the container ends. The large radius of curvature of the transition section from the side wall to the top wall gives the anti-collision groove high structural strength.

[0071] Preferably, anti-collision grooves 30 are provided at the connections between the four bottom corner pieces 20 and the end members 10 of the container 100. The anti-collision grooves 30 extend along the length of the container 100, and no sidewalls are provided at both ends of the extension direction of the anti-collision grooves 30. The lower end (sidewall) of the anti-collision grooves 30 does not extend downward beyond the lower surface of the bottom corner pieces 20. The anti-collision grooves 30 are cylindrical, that is, the cross-section is the same in the extension direction.

[0072] The first inner surface 31 and the second inner surface 33 are both curves with non-zero curvature in the cross-section of the anti-collision groove 30. The first curved surface portions 31b and 33b are also curves with non-zero curvature in the cross-section of the anti-collision groove 30. The curvature of the same curve segment can be constant or gradually changing, but the positive and negative signs of the curvature are consistent. This allows the anti-collision groove 30 to have higher strength and better cushioning and guidance against collision impacts. The cross-section of the anti-collision groove 30 refers to the plane intercepted by the planes extending in the width direction D1 and the height direction D2 of the container 100.

[0073] Optionally, both the first inner surface 31 and the second inner surface 33 are circular arcs in the cross-section of the anti-collision groove 30, that is, both the first inner surface 31 and the second inner surface 33 are portions of a cylindrical surface cut along the axial direction. Optionally, one of the first inner surface 31 and the second inner surface 33 is a circular arc in the cross-section of the anti-collision groove 30. Preferably, the radius of the circular arc is greater than 12 mm.

[0074] Optionally, both the first curved surface portions 31b and 33b are circular arcs in the cross-section of the anti-collision groove 30. Alternatively, one of the first curved surface portions 31b and 33b is a circular arc in the cross-section of the anti-collision groove 30. Preferably, the radius of the circular arc is greater than 12 mm.

[0075] The inner top surface 32 can be a plane or a curved surface (with a non-zero curvature). When the inner top surface 32 is curved, the inner surface of the anti-collision groove 30 forms a curve with consistent positive and negative curvature in the cross-section of the anti-collision groove 30. That is, the first inner side surface 31, the inner top surface 32, and the second inner side surface 33 are connected in the cross-section of the anti-collision groove 30 to form a curve with consistent positive and negative curvature. In other words, the inner surface of the anti-collision groove 30 is a curved and convex surface.

[0076] Optionally, the inner surface is an arc in the cross-section of the anti-collision groove 30, or in other words, the first inner side surface 31, the inner top surface 32, and the second inner side surface 33 are connected in the cross-section of the anti-collision groove 30 as an arc. That is, the inner surface of the anti-collision groove 30 is a portion of a cylindrical surface cut along the axial direction. Preferably, the radius of the arc is greater than 12 mm.

[0077] Optionally, the first curved surface portion 31b of the first inner side surface 31, the inner top surface 32, and the first curved surface portion 33b of the second inner side surface 33 are connected as an arc in the cross-section of the anti-collision groove 30. That is, the first curved surface portion 31b, the inner top surface 32, and the first curved surface portion 33b are connected as a portion of a cylindrical surface cut off along the axial direction.

[0078] The anti-collision groove 30 also has an outer surface facing outward. The outer surface includes a first outer side surface 34, an outer top surface 35, and a second outer side surface 36 connected in sequence. The first outer side surface 34 is the surface of the anti-collision groove 30 facing the bottom corner piece 20, and the first outer side surface 34 and the first inner side surface 31 are the surfaces of the first sidewall 30a on both sides of the container 100 in the width direction D1, respectively; the outer top surface 35 is the surface of the anti-collision groove 30 facing upward; the second outer side surface 36 is the surface of the anti-collision groove 30 on the side opposite to the first outer side surface 34, and the second outer side surface 36 and the second inner side surface 33 are the surfaces of the second sidewall 30c on both sides of the container 100 in the width direction D1, respectively.

[0079] The first outer surface 34 is at least partially connected to the bottom corner piece 20, the outer top surface 35 is connected to the end member 10, and the second outer surface 36 is connected to the end member 10.

[0080] The first outer surface 34, the outer top surface 35, and the second outer surface 36 can all be curved surfaces or flat surfaces. For example, the first outer surface 34, the outer top surface 35, and the second outer surface 36 are connected by an arc in the cross-section of the anti-collision groove 30. Thus, the connection between the outer surface of the anti-collision groove 30 and the end member 10 is a smooth curved surface. When the anti-collision groove 30 is welded to the bottom corner member 20 and the end member 10, the weld transition is smooth, improving the process performance of automatic welding of the anti-collision groove 30 and enhancing welding quality and efficiency. For example, the second outer surface 36 is connected by an arc in the cross-section of the anti-collision groove 30.

[0081] Alternatively, the second outer surface 36 includes a smoothly connected second planar portion 36a and a second curved surface portion 36b. The second curved surface portion 36b connects the second planar portion 36a and the outer top surface 35. Preferably, the second curved surface portion 36b is a smooth curved surface.

[0082] Optionally, the first outer surface 34 includes a smoothly connected second planar portion 34a and a second curved surface portion 34b. The second planar portion 34a / 36a is a plane, and the second curved surface portion 34b / 36b is a curved surface with non-zero curvature. The second planar portion 34a is connected to the bottom corner piece 20. The second curved surface portion 34b connects the second planar portion 34a and the outer top surface 35, and the second curved surface portion 34b is a smooth curved surface.

[0083] When the first outer surface 34 is a curved surface or includes a smoothly connected second planar portion 34a and a second curved surface portion 34b, the first outer surface 34 is also connected to the end member, that is, the first outer surface 34, the outer top surface 35 and the second outer surface 36 are all connected to the end member 10.

[0084] Preferably, at least one of the first outer surface 34 and the second outer surface 36 is provided with a recess. This saves material used in the manufacture of the anti-collision groove. Specifically, when the first outer surface 34 is flat and the first inner surface 31 is curved or includes a first curved surface portion 31b, a portion of the first sidewall 30a has a larger thickness, and the first sidewall 30a is provided with at least one groove 37, meaning the first outer surface 34 has at least one recess. When the second outer surface 36 is flat and the second inner surface 33 is curved or includes a first curved surface portion 33b, a portion of the second sidewall 30c has a larger thickness, and the second sidewall 30c is provided with at least one groove 37, meaning the second outer surface 36 has at least one recess.

[0085] Preferably, at least one of the inner and outer surfaces of the anti-collision groove 30 is symmetrical about a plane perpendicular to the width direction D1 of the container 100. That is, the first inner surface 31 and the second inner surface 33 are preferably symmetrically arranged. The first outer surface 34 and the second outer surface 36 are preferably symmetrically arranged.

[0086] The following is a reference to the appendix. Figure 2-8 This section introduces some specific embodiments of the anti-collision groove 30.

[0087] like Figure 2 As shown, the inner top surface 32 is a plane, and the first inner side surface 31 includes a first planar portion 31a and a first curved surface portion 31b. The second inner side surface 33 includes a first planar portion 33a and a first curved surface portion 33b. The first planar portion 33a has a dimension h1 in the height direction D2 of the container 100, and the first curved surface portion 33b has a dimension h2 in the height direction D2 of the container 100, where h2 > h1. Similarly, in the height direction D2 of the container 100, the dimension of the first curved surface portion 31b is larger than the dimension of the first planar portion 31a. The first curved surface portion 33b is an arc in the cross-section of the anti-collision groove 30, for example, a quarter arc or less than a quarter arc.

[0088] Meanwhile, the first outer surface 34, the outer top surface 35, and the second outer surface 36 are all planar.

[0089] like Figure 3 As shown, the inner top surface 32 is a plane, and the first inner side surface 31 includes a first planar portion 31a and a first curved surface portion 31b. The second inner side surface 33 includes a first planar portion 33a and a first curved surface portion 33b.

[0090] Both the first outer surface 34 and the outer top surface 35 are planar. The second outer surface 36 includes a second planar portion 36a and a second curved portion 36b. Preferably, the thickness of the second sidewall 30c is substantially uniform. In the height direction D2 of the container 100, the dimension of the second curved portion 36b is larger than the dimension of the second planar portion 36a. In this design, the connection between the first outer surface 34 and the bottom corner piece 20 is more robust, and less material is required for the anti-collision groove 30.

[0091] like Figure 4 As shown, the inner top surface 32 is a plane, and the first inner side surface 31 includes a first planar portion 31a and a first curved surface portion 31b. The second inner side surface 33 includes a first planar portion 33a and a first curved surface portion 33b.

[0092] The outer top surface 35 is a plane. The first outer side surface 34 and the second outer side surface 36 are planes with recesses, that is, the first side wall 30a is provided with a groove on one side of the first outer side surface 34; the second side wall 30c is provided with a groove on one side of the second outer side surface 36.

[0093] like Figure 5 As shown, the inner top surface 32 is a plane, and the first inner side surface 31 includes a first planar portion 31a and a first curved surface portion 31b. The second inner side surface 33 includes a first planar portion 33a and a first curved surface portion 33b.

[0094] The outer top surface 35 is planar. The first outer side surface 34 includes a second planar portion 34a and a second curved portion 34b. In the height direction D2 of the container 100, the dimension of the second curved portion 34b is larger than the dimension of the second planar portion 34a. The second outer side surface 36 includes a second planar portion 36a and a second curved portion 36b. Preferably, the thickness of the first sidewall 30a is substantially uniform. The thickness of the second sidewall 30c is substantially uniform.

[0095] like Figure 6 As shown, the first inner surface 31, the inner top surface 32, and the second inner surface 33 are all curved surfaces. The first outer surface 34, the outer top surface 35, and the second outer surface 36 are all curved surfaces.

[0096] Preferably, the inner surface is an arc segment in the cross-section of the anti-collision groove 30, with the central angle corresponding to the arc being less than or equal to 180°, and the radius of the arc being, for example, 15 mm. The outer surface is also an arc segment in the cross-section of the anti-collision groove 30. The outer surface of the anti-collision groove 30 has a shape substantially the same as the inner surface, making the outer surface of the anti-collision groove 30 a smooth curved surface. The welding transition is smooth, facilitating welding and improving efficiency and welding quality.
