Abstract
Description
Technical Field
[0001] The invention relates to a carrier, and in particular to a base and a foot of the carrier. Background Art
[0002] There are various types of carriers on the market, which are suitable for storage, display and transportation of various objects. For easy transportation, the bottom of the carrier is equipped with a base and feet, so that the bottom of the carrier is at a certain distance from the ground, which is convenient for forklifts to carry.
[0003] The carriers currently on the market require the forklift's tines to be inserted into the bottom of the container for transportation. Due to the uncertainty of the carrier's placement direction, the four sides of the carrier need to have space for the forklift's tines to enter and exit. Generally, the minimum width of the outermost edge of the fork of a fixed-tined forklift is about 540mm. Based on this prerequisite, for some carriers with limited external dimensions (for example: length and width dimensions of 800mm*600mm), the space in the short direction is relatively compact.
[0004] The connection method between the base 1 and the foot 2 of the vehicle currently on the market is mainly: a boss 3 extends from the bottom of the base 1 of the vehicle, and a cavity 4 is provided on the top of the foot 2. The cavity 4 of the foot 2 cooperates with the boss 3 at the bottom of the base of the vehicle, that is, the boss 3 is inserted into the cavity 4, and the foot and the base are connected to each other by bolts 5, such as Fig.10 shown.
[0005] During storage or logistics handling, the forklift's teeth need to frequently enter and exit the carrier's foot. Due to the short-distance space limitation, the forklift's teeth will inevitably hit the carrier's foot during actual operation. Since the connection between the carrier's foot and the carrier base is: the cavity of the foot device is fixedly connected to the boss of the carrier base. As a result, when the foot is hit, the force transmission causes the cavity of the foot and the boss of the carrier base to break together, thereby increasing the subsequent maintenance cost. Summary of the invention
[0006] The purpose of the present invention is to provide a carrier which can protect the foot and the base when the foot is impacted by external force, thereby reducing the subsequent maintenance cost.
[0007] To achieve the above-mentioned purpose, the present invention provides a carrier, which has a base and two feet, and the two feet are respectively installed on the lower sides of both ends of the base, a forklift hole is formed between the two feet, and the lower sides of both ends of the base are provided with a first boss protruding downward from the lower surface of the base, and both ends of each of the feet are provided with a second boss protruding upward from the upper surface of the foot, and a forklift hole is formed between the two second bosses, and the carrier further has a sheath and a connecting piece, wherein the bottom surface of the first boss abuts against the top surface of the corresponding second boss, the sheath surrounds the outer surfaces of the first boss and the second boss abutting against each other, and the connecting piece passes through the first boss and the second boss to connect the feet and the base to each other.
[0008] In one embodiment, there is a gap between the inner surface of the sheath and the outer surfaces of the first boss and the second boss.
[0009] In one embodiment, the base is further provided with a groove, and the groove is located at a position of the base corresponding to the first boss. The carrier is further provided with an insert, wherein the insert is placed in the groove of the base, and the connecting member passes through the second boss and the first boss in sequence and is connected to the insert.

It should be noted that the term "or" is generally employed in its sense including "and / or" unless the context clearly dictates otherwise.
[0036] In the following description, in order to clearly show the structure and working mode of the present invention, many directional words will be used for description, but the words "front", "back", "left", "right", "outside", "inside", "outward", "inward", "up", "down", etc. should be understood as convenient terms and should not be understood as restrictive terms.
[0037] like Figure 1-8As shown, the carrier has a base 6 and two feet 7. The base 6 is formed by an upper part 61 and a lower part 62 connected to each other. The upper part 61 and the lower part 62 can be made of, for example, a high-strength plastic material and connected to each other by welding. Depending on the type of carrier, the upper part 61 can have various desired structures. For example, when the carrier is a foldable container, the upper part can be provided with a hinge structure and connected to the side panel of the container through the hinge structure. Of course, as needed, the upper part 61 and the lower part 62 can also be made into one piece. In the present application, the carrier can be a pallet, an intermediate bulk container or a turnover box, etc. The length and width dimensions of the carrier can be, for example, 800mm*600mm.
[0038] The two feet 7 are respectively mounted on the lower sides of both ends of the base 6. The two feet 7 are parallel to each other and a forklift hole 7a is formed between the two feet 7. The forklift hole 7a is used for inserting the fork of a forklift when transporting the carrier.
[0039] The lower sides of the left and right ends of the base 6 are provided with first bosses 12 protruding downward from the lower surface of the base. Each of the left and right ends of the base 6 has two first bosses 12. The two first bosses 12 at one end are respectively located at the two corners of the end. In other words, the lower surface of the base 6 is provided with four first bosses 12, which are respectively located at the four corners of the base 6. The first boss 12 is provided with a mounting hole 12a inside. Both ends of each foot 7 are provided with a second boss 13 protruding upward from the upper surface of the foot 7. The second boss 13 is provided with a mounting hole 13a. The second boss 13 abuts against the corresponding first boss 12. The connecting member 9 passes through the mounting hole of the second boss 13 and the mounting hole of the first boss 12 to connect the foot 7 and the base 6 to each other. Here, the first boss 12 of the base 6 is connected to the second boss of the foot 7 in face-to-face contact. When impacted by external force, the boss of the base and the boss of the foot can be displaced, thereby achieving the effect of buffering and absorbing energy.
[0040] The outer surfaces of the first boss 12 and the second boss 13 are surrounded by the sheath 8. The shape of the sheath 8 matches the combined shape of the first boss 12 and the second boss 13. In this embodiment, the sheath 8 is a rectangular sleeve with upper and lower openings. The sheath 8 can be made of a metal material with higher strength.
[0041] There is a gap between the inner surface of the sheath 8 and the outer surfaces of the first and second bosses. Thus, there is a space between the inner surface of the sheath and the outer surfaces of the first and second bosses, and when the sheath is hit by an external force, there is a certain deformation buffer space. The formation of the gap can be achieved by providing a plurality of mutually spaced ribs 14 on the outer surface of the first boss, and a plurality of mutually spaced ribs 15 on the outer surface of the second boss 13. Preferably, the gap size is 3mm-8mm. More preferably, the gap size is 4mm-6mm.
[0042] In the present application, the height of the first boss 12 is much smaller than the height of the second boss 13. In one embodiment, the height of the first boss is 1 / 12 to 1 / 4 of the height of the second boss. Preferably, the height of the first boss is 1 / 10 to 1 / 5 of the height of the second boss. In this way, when the impact force exceeds the limit that the sheath can withstand, the second boss of the foot becomes the first force-bearing member, thereby protecting the base.
[0043] In one embodiment, the height of the first boss 12 is D1, and the value of D1 is between 5mm-25mm. The applicant has found through research that if the value of D1 is too small, it cannot form an effective positioning with the outer sheath; if the value of D1 is too large, it is easy to be damaged when impacted by external force. The height of the second boss 13 is D2, and the value of D2 is determined by the height D3 of the sheath and the height D1 of the first boss, that is, D2 = D3-D1. Usually, the value of D3 is between 70mm-90mm.
[0044] The base 6 is further provided with a groove 11. The groove 11 is located at a position corresponding to the first boss 12. An insert 10 is placed in the groove 11. The connecting member 9 passes through the second boss 13 and the first boss 11 in sequence and is connected to the insert 10, thereby connecting the foot and the base to each other. A positioning rib 11a extends upward from the bottom surface of the groove 11 of the base 6. The insert 10 is provided with a slot 10a. The positioning rib 11a is inserted into the slot 10a, thereby installing the insert 10 in the groove 11 of the base 6.
[0045] In one embodiment, the insert 10 is further provided with a threaded hole 10b. In this case, the connecting member 9 is a bolt. The bolt 9 passes through the mounting hole of the second boss 13 and the mounting hole of the first boss 12 in sequence and is screwed into the threaded hole 10b of the insert 10 to connect the foot 7 to the base 6. Preferably, the insert is made of metal. When impacted by external force, the metal insert 10 acts as a direct force-bearing member, which can reduce damage to the base.
[0046] In this embodiment, a connecting column 16 protruding upward from the upper surface of each foot 7 is further provided in the middle portion thereof. The connecting column 16 is provided with a cavity 16a. A third boss 17 protruding downward from the lower surface of the base is further provided in the middle portion of one end of the base 6. The third boss 17 is inserted into the cavity 16a. A forklift hole 18 is also formed between the second boss 13 and the connecting column 16.
[0047] Fig. 9 yes Figure 1 The force analysis diagram of the base and foot of the vehicle. Fig. 9 It can be seen that the foot stress is 82Mpa and the base stress is 25Mpa. In comparison, under the same conditions, the foot stress of similar vehicles currently available on the market is 197Mpa and the base stress is 68Mpa, see Fig.11It can be seen that the stress of the base and the foot of the present application is greatly reduced.
[0048] The carrier of the present application can protect the base and the base through deformation and energy absorption of the outer sheath and relative displacement of the connection point between the base and the base when the base is impacted by external force. When the impact force exceeds the energy absorption limit of the sheath, due to the height characteristics of the base boss and the base boss, the base bears most of the external force, thereby protecting the base to the greatest extent and reducing the subsequent maintenance cost.
[0049] Preferred embodiments of the present invention have been described above in detail, but it should be understood that aspects of the embodiments can be modified, if necessary, to employ aspects, features and concepts of the various patents, applications and publications to provide further embodiments.
[0050] These and other changes can be made to the embodiments in light of the above detailed description.In general, in the claims, the terms used should not be considered limited to the specific embodiments disclosed in the specification and the claims, but should be construed to include all possible embodiments along with the full scope of equivalents to which these claims are entitled.
