Detailed Description
The technical solutions of the exemplary embodiments provided in the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention. The following embodiments and their technical features may be combined with each other without conflict.
Directional phrases used herein, such as, for example, upper, lower, top, bottom, front, rear, left, right, inner, outer, lateral, peripheral, central, horizontal, transverse, vertical, longitudinal, axial, radial, uppermost or lowermost, etc., refer only to the orientation of the figure. Accordingly, the directional terms used are used for explanation and understanding of the present invention, and are not used for limiting the present invention. In addition, the same reference numerals are used to identify structural elements having the same or similar characteristics.
Fig. 1 is a schematic structural diagram of a tray according to an embodiment of the present invention. As shown in fig. 1, the tray 10 may include a tray body 11, an elastic member 12, a wedge 13, and a top plate 14.
The top of the tray main body 11 is provided with a bearing surface.
The lower end of the elastic element 12 abuts against the bearing surface of the top of the tray body 11, for example, the lower end of the elastic element 12 can be directly fixed on the bearing surface of the top of the tray body 11.
The wedge block 13 is disposed at a side of the tray main body 11, and its lateral dimension is gradually reduced in a gravity direction. In the free state (which can be regarded as the state that the pallet 10 is not loaded with goods), the top surface of the wedge-shaped block 13 is higher than the loading surface of the top of the pallet body 11. The wedge block 13 is a wedge-shaped structural block, and the cross-sectional shape thereof may be a trapezoid as shown in fig. 1, but the wedge block 13 may be a triangular cross-sectional structural block as shown in fig. 3.
Referring to fig. 1 and fig. 2, the inner side surface of the wedge block 13 is an inclined sliding surface 131, and the inclined sliding surface 131 is a surface having an acute angle with the gravity direction. The inclined slide surface 131 of the wedge block 13 is in contact with the side of the tray main body 11, and can slide obliquely upward and obliquely downward with respect to the tray main body 11 along the inclined slide surface 131.
The top plate 14 is disposed above the wedge block 13, an upper end of the elastic member 12 abuts against a side (e.g., a lower side shown in fig. 1) of the top plate 14 facing the tray main body 11, for example, an upper end of the elastic member 12 may be directly and fixedly connected to a lower side of the top plate 14.
Referring to fig. 1 and 4, when the goods 20 are loaded on the top plate 14, the elastic member 12 is gradually contracted by the downward pressure, so as to slowly move the goods 20 and the top plate 14 downward, thereby buffering the loading of the goods 20 and reducing the risk of damage to the goods 20.
In the process, the goods 20 press the top plate 14 downwards and enable the top plate 14 to move downwards, the top plate 14 drives the wedge-shaped block 13 to move downwards, and the wedge-shaped block which moves downwards movesThe inclined slide surface 131 of the tray body 13 is stopped by the side of the tray body 11, and moves downward and toward the outside of the tray body 11. Until the top plate 14 moves downwards to the limit position, the wedge block 13 stops moving, and at this time, the wedge block 13 can be considered to move to the limit position along the horizontal direction. It can be seen that the transverse dimension d of the tray 100The dimension d of the two wedge blocks 13 arranged at a distance from each other moving in the horizontal direction1Transverse dimension d of the tray main body 112Sum, i.e. d0＝2*d1+d2。
Compared with the transverse dimension d of the existing tray (i.e., the tray main body 11)2It is clear that the transverse dimensions of the tray 10 are increased by 2 x d1Then d is0＞d2. To the application scene that the tray 10 was placed in the reservation position in the container and was placed side by side, the clearance between two arbitrary adjacent trays 10 diminishes, even meet the jolt condition such as the road height is uneven, the dynamics of colliding each other between the adjacent tray 10 diminishes to can be favorable to reducing the risk that goods 20 damaged. Especially, for fragile goods 20 such as glass substrates, the effect of reducing the risk of damage is more remarkable.
When the cargo 20 is unloaded from the top plate 14, the elastic members 12 gradually expand and exert an upward force on the top plate 14 while abutting against the top plate 14, and the top plate 14 drives the wedge 13 upward along the inclined slide surface 131. When the elastic member 12 is extended to the position of the free state, the top plate 14 moves up to the limit position, and the wedge block 13 stops moving and returns to the initial position. At this time, the tray 10 has a lateral dimension d0Can be considered as the transverse dimension d of the tray body 112。
The cargo 20 includes, but is not limited to, various types of display panels such as liquid crystal panels, Organic Light-Emitting Diode (OLED) display panels, and the like, and the manufacturing materials and the sizes of the structural elements of the tray 10 can be selected according to actual needs to be suitable for various types of cargo 20, which is not limited herein.
In summary, the pallet 10 is additionally provided with the elastic member 12 and the top plate 14 on the carrying surface of the pallet main body 11 and the wedge block 13 on the side of the pallet main body 11, the pallet 10 utilizes the telescopic characteristic of the elastic member 12 to buffer the loading of the goods 20, the risk of damage to the goods 20 can be reduced, and when the goods 20 are loaded, the top plate 14 presses the wedge block 13 downwards, the wedge block 13 slides relative to the pallet main body 11 along the inclined sliding surface 131, and the wedge block 13 moves towards the outer side of the pallet main body 11 in the horizontal direction, so that the transverse dimension of the pallet 10 is increased, the gap between adjacent pallets 10 can be reduced, and the risk of damage to the goods 20 is reduced.
Based on this characteristic, with continued reference to fig. 1, in one embodiment:
the tray body 11 can be regarded as an existing tray, and the bearing surface arranged on the top of the tray body can be regarded as the bearing surface of the existing tray. The bottom of the tray main body 11 may be provided with an insertion channel 111, and a boom of a lifting device such as a forklift is inserted into the insertion channel 111, so that the tray main body 11 and the goods 20 carried by the tray main body can be lifted by applying an upward force, thereby facilitating transportation of the tray 10 and the goods 20 loaded on the tray main body. The difference from the existing tray is that, as shown in fig. 5, a groove 112 for accommodating the wedge-shaped block 13 is formed on the side of the tray main body 11, the groove 112 may be defined by three groove walls, two opposite and spaced groove walls 112a are triangular, and the other groove wall 112b is a rectangular inclined surface, and an included angle between the inclined surface and the gravity direction is equal to an inclined angle of the inclined sliding surface 131.
The elastic members 12 may be springs, and the number of the springs may be at least two, and the springs may be uniformly distributed on the bearing surface of the tray body 11 to achieve uniform stress. Of course, the elastic member 12 may also be other structural members that can be extended and retracted along the vertical direction, for example, the elastic member 12 may include a plurality of arc-shaped elastic pieces connected end to end, when the elastic pieces are stressed by the cargo 20, the elastic pieces are deformed by pressure and the radian of the elastic pieces increases, so as to realize the contraction of the elastic member 12 as a whole, and when the cargo 20 is removed from the pallet body 11, the elastic pieces recover to be deformed and the radian of the elastic pieces changes to a value in a free state, so as to realize the extension of the elastic member 12 as a whole.
The top plate 14 may be a flat plate made of a single metal, metal alloy or nonmetal with high strength, low deformation and light weight. The top plate 14 may be completely overlapped with the top surface of the tray body 11, and the top surface of the top plate 14 may be used as the top surface of the tray 10 instead of the top surface of the tray body 11.
The wedge blocks 13 are provided on the side of the tray main body 11, and the number thereof may be two as shown in fig. 1, and they are provided at an interval. The wedge-shaped blocks 13 are correspondingly accommodated in the grooves 112 one by one, the transverse dimension of the wedge-shaped blocks 13 is gradually reduced, namely gradually narrowed, along the gravity direction, and in addition, the height of the wedge-shaped blocks 13 can be smaller than that of the tray main body 11. Referring to fig. 1, 2 and 5, the inclined sliding surface 131 of the wedge-shaped block 13 is attached to the groove wall 112b of the groove 112 on the side of the tray body 11, the surfaces 132 on both sides of the inclined sliding surface 131 can be attached to the two groove walls 112a of the groove 112, respectively, in a free state, the top surface 134 of the wedge-shaped block 13 is spaced from the top plate 14, and the side surface 135 of the wedge-shaped block 13 is flush with the side surface of the tray body 11.
With reference to fig. 1, the tray 10 is further provided with a sliding rod 15, and the extending direction of the sliding rod 15 is parallel to the bearing surface of the top of the tray main body 11, i.e. the sliding rod 15 extends along the horizontal direction. The slide rod 15 is connected to the underside of the top plate 14 and penetrates the wedge 13 in the direction of extension thereof, wherein the connection between the top plate 14 and the wedge 13 is established, and the top plate 14 can drive the wedge 13 to move up or down. It should be noted that the distance between the bottom of the sliding rod 15 and the top plate 14 may be smaller than or equal to the extreme compression dimension of the elastic member 12, when the elastic member 12 is compressed to the extreme position, the distance between the top plate 14 and the bearing surface of the top of the tray main body 11 is minimum, and the sliding rod 15 just contacts or does not contact the bearing surface of the top of the tray main body 11, so as to avoid adverse effect on the connection stability between the sliding rod 15 and the top plate 14.
In one embodiment, the connection between the slide rod 15 and the underside of the top plate 14 can be achieved by a connecting rod 151 of fixed length, wherein the top plate 14 simultaneously drives the wedge 13 to move up or down. The connecting rod 151 includes, but is not limited to, a metal rod.
In another embodiment, the connection between the slide rod 15 and the underside of the top plate 14 can be realized by means of a telescopic element, i.e. the connecting rod 151 in fig. 1 is replaced by a telescopic element which can change its dimension in the direction of gravity. When the elastic member 12 is compressed to the limit position, the distance between the top plate 14 and the bearing surface of the top of the tray main body 11 is minimum, the telescopic member is compressed, the distance between the bottom of the sliding rod 15 and the top plate 14 is reduced, and the sliding rod 15 can be just contacted or not contacted with the bearing surface of the top of the tray main body 11, so that the adverse effect on the connection stability between the sliding rod 15 and the top plate 14 can be avoided.
Further, both ends of the sliding rod 15 may be provided with stoppers 152, and when the wedge 13 moves to the limit position along the extending direction of the sliding rod 15, the stoppers 152 abut against the side surface 135 of the wedge 13 to prevent the wedge 13 from being separated from the sliding rod 15.
For improved aesthetics, the side surface 135 of wedge-shaped block 13 may be provided with a recessed area, i.e. a recessed area, in which the blocking member 152 is completely received without being exposed when the wedge-shaped block 13 is moved to the extreme position along the extension direction of the sliding rod 15 (as shown in fig. 4), whereby the transverse dimension d of the pallet 10 is taken along when the pallet 10 is loaded with the goods 200Not including the lateral dimension of the stop 152. Optionally, the outer side of stop 152 is flush with side 135 of wedge block 13.
Of course, no recess is provided for side 135 of wedge-shaped block 13, and stop 152 abuts against side 135 of wedge-shaped block 13 when wedge-shaped block 13 is moved to the limit position in the extension direction of slide rod 15, whereby transverse dimension d of pallet 10 is measured when pallet 10 is loaded with goods 200The lateral dimension of the blocking member 152 on both sides is included.
In a particular embodiment, the sliding rod 15 can be a telescopic element that can vary its transverse dimension along the extension direction of the sliding rod 15. For example, the sliding rod 15 may include at least two rods, the at least two rods are sequentially sleeved along the extending direction of the sliding rod 15, when the wedge 13 moving towards the outside abuts against the blocking member 152, an outward force is applied to the blocking member 152, the blocking member 152 drives a rod connected thereto to move outward, for example, an originally unexposed portion of the rod extends out of the rod sleeved outside the blocking member, so that the sliding rod 15 extends, and the transverse dimension is increased. When the cargo 20 is unloaded from the top plate 14, the wedge-shaped block 13 moving inwards and the rod body penetrating through the wedge-shaped block 13 move inwards, for example, the pulled-out portion of the rod body is retracted into the rod body sleeved outside, so that the sliding rod 15 is retracted, the transverse dimension is reduced, and the original dimension is finally restored when the cargo 20 is not loaded.
