The following describes in detail the structure, connection mode and functional relationship of the main components of the positioning device 200 proposed in the present disclosure, with reference to the above drawings.
As shown in fig. 1 to 3, in the present embodiment, the positioning device 200 proposed by the present disclosure is illustrated by taking two stacked box boards applied to positioning a carton as an example. In other embodiments, the positioning device 200 can also be applied to positioning two or more stacked plates of other types, and is not limited to this embodiment. For ease of understanding, the two boxboards will be defined in the following description as the first boxboard 101 and the second boxboard 102, respectively. Further, taking the positional relationship shown in the drawings as an example, the first box board 101 is the one positioned above the two box boards, and the second box board 102 is the one positioned below the two box boards. Similarly, the positional relationship between "upper" and "lower" in the following description is also defined by the positional relationship shown in the drawings, and does not limit the positional relationship of the components of the positioning apparatus 200 in other spatial states.
As shown in fig. 1 to 3, in the present embodiment, the positioning device 200 proposed by the present disclosure can be applied to positioning the first and second boxboards 101 and 102 that are stacked. The first box plate 101 and the second box plate 102 are respectively provided with openings, and the two openings have the same shape and are overlapped in position. When two boxboards are stacked, the two openings overlap to collectively form a locating hole. On the basis, the positioning apparatus 200 proposed by the present disclosure at least includes a first positioning seat 210 and a second positioning seat 220. Specifically, the first positioning seat 210 has a cylindrical structure. The upper end socket of the first positioning seat 210 extends outwards to form a first clamping plate 211, and the shape of the first positioning seat 210 is matched with the hole type of the positioning hole. The second positioning seat 220 and the first positioning seat 210 are an integral structure. The second positioning seat 220 can be accommodated in the tube cavity of the first positioning seat 210 in a foldable manner, and the second positioning seat 220 abuts against the wall of the tube cavity of the first positioning seat 210 when being unfolded. The lower end of the second positioning seat 220 extends outwards to form a second clamping plate 221. Through the above design, when the positioning device 200 is installed in the positioning hole, the first positioning seat 210 is sleeved in the positioning hole, and the first clamping plate 211 is clamped on the surface of the first box plate 101 (i.e. the upper surface of the first box plate 101 facing away from the second box plate 102). When the second positioning seat 220 is unfolded, the second clamping plate 221 extends out of the lower cylindrical opening of the first positioning seat 210 and is clamped on the surface of the second box board 102 (i.e., the lower surface of the second box board 102 facing away from the first box board 101). Accordingly, the positioning device 200 provided by the present disclosure can implement a reliable and convenient positioning function. Moreover, since the first positioning seat 210 and the second positioning seat 220 are integrated, the positioning device 200 provided by the present disclosure has the advantages of simple structure, convenience in processing, low cost, and the like.
Preferably, in the present embodiment, the cylinder size of the first positioning seat 210 may be preferably larger than the size of the positioning hole. Through the above design, the first positioning seat 210 can form an interference fit relationship when being sleeved in the positioning hole. The cylinder size of the first positioning seat 210 may be understood as, for example, the size of the outer periphery of the first positioning seat 210, and the size of the positioning hole may be understood as, for example, the aperture of the positioning hole. In other embodiments, the cylinder of the first positioning seat 210 may also be equal to the positioning hole. Certainly, in order to meet the convenience of installation and assembly and have a lower requirement on the positioning effect, the size of the cylinder body of the first positioning seat 210 may be slightly smaller than that of the positioning hole, which is not limited by the present embodiment.
As shown in fig. 4 and 5, in the present embodiment, the height of the cylinder of the first positioning seat 210 is greater than the depth of the positioning hole. In other embodiments, the barrel height of the first positioning seat 210 may preferably be equal to the depth of the positioning hole. Through the design, when the first positioning seat 210 is sleeved on the positioning hole, the lower end cylinder opening of the first positioning seat 210 is flush with the surface of the second box plate 102, so that the operation of an operator is facilitated, and the arrangement of other structures is facilitated. Moreover, the height of the cylinder of the first positioning seat 210 may also be smaller than the depth of the positioning hole, and is not limited in this embodiment.
Preferably, as shown in fig. 1 to 3, in the present embodiment, the first catch plate 211 may preferably have a ring-shaped plate-shaped structure, and the first catch plate 211 surrounds an outer circumference formed at an upper end cylindrical opening of the first positioning seat 210. Through the design, the contact area between the first clamping plate 211 and the upper surface of the first box plate 101 can be increased, so that the positioning effect of the positioning device 200 and the first box plate 101 is optimized. In other embodiments, the first fastening board 211 may also have other structures, such as a multi-segment structure, and the like, and is not limited to this embodiment.
As shown in fig. 1 to 3, in the present embodiment, the hole pattern of the positioning hole is a long hole shape with an approximate rectangle, and the section of the cylinder cavity of the first positioning seat 210 is a long hole shape with an approximate rectangle, that is, the cylinder cavity of the first positioning seat 210 has two cavity walls which are opposite and parallel. On this basis, when the second positioning seat 220 is unfolded, the second positioning seat 220 is pressed against the two cavity walls of the first positioning seat 210. Specifically, the second positioning socket 220 may preferably be an elastic folding plate. The elastic folding plate may include four plate portions 222 connected in sequence, two adjacent plate portions 222 are elastically connected by a groove structure 223, and respective free ends of the two plate portions 222 located at both sides (i.e., the other ends opposite to the connecting ends connecting the adjacent plate portions 222) are connected to one of the two cavity walls. With the above design, when the elastic folding plate is unfolded, the two plate portions 222 located in the middle part abut against the other one of the two cavity walls. In other embodiments, the second positioning seat 220 can also adopt other structures, such as an arc-shaped elastic sheet, and the like, which is not limited to the embodiment.
Further, as shown in fig. 1 to 3, based on the design that the elastic folding plate includes four plate portions 222, in the present embodiment, when the elastic folding plate is folded, the cross section of the elastic folding plate in the horizontal plane is substantially M-shaped, and when the elastic folding plate is unfolded, the cross section of the elastic folding plate in the horizontal plane is substantially n-shaped. It should be noted that the shape of the folded elastic folding plate can be defined by the opening position of the groove structure 223. Taking this embodiment as an example, the elastic folding plate is regarded as a whole plate, two ends of the elastic folding plate are respectively connected to one of two cavity walls (defined as a first cavity wall) of the cylindrical cavity of the first positioning seat 210, the four plate portions 222 are designed by forming three groove structures 223 on the elastic folding plate, when the three groove structures 223 are distributed at intervals along the horizontal direction, the groove structure 223 located in the middle can be formed on one side surface of the elastic folding plate facing the first cavity wall, and the two groove structures 223 located on two sides can be formed on one side surface of the elastic folding plate facing away from the first cavity wall. In other embodiments, the number and the opening positions of the groove structures 223 may also adopt other designs, so that the second positioning seat 220 presents different structural configurations in the unfolded state and the folded state when being an elastic folded plate, which is not limited by the present embodiment.
Further, as shown in fig. 1 to 3, based on the design that the elastic folding plate includes four plate portions 222, in the present embodiment, the second positioning seat 220 may preferably include two second snap plates 221. Specifically, the two second locking plates 221 are formed at the lower ends of the two plate portions 222 on both sides of the elastic folding plate, respectively. Taking the structure of the elastic folding plate in the unfolded state and the folded state as an example in this embodiment, when the elastic folding plate is unfolded, the two second clamping plates 221 respectively extend out of the positioning holes along with the two plate portions 222 on the two sides and are respectively clamped on the lower surface of the second box plate 102. When the elastic folding plate is folded, the two second fastening plates 221 are retracted inwards along with the two plate portions 222 on the two sides respectively. According to the size of the positioning hole (approximately understood as the size of the cylindrical cavity of the first positioning seat 210), the width of the second clamping plate 221 in the horizontal direction can be designed, so that when the elastic folding plate is folded, the projection pattern of the second clamping plate 221 on the horizontal plane completely falls into the projection pattern of the cylindrical body of the first positioning seat 210 on the horizontal plane.
As shown in fig. 1 to 5, in the present embodiment. The positioning device 200 proposed by the present disclosure may also preferably include a support plate 230. Specifically, the supporting plate 230 is rotatably disposed in the cylinder of the first positioning seat 210, one end of the supporting plate 230 is movably connected to the cylinder wall (preferably, the first cylinder wall) of the cylinder of the first positioning seat 210, and the supporting plate 230 can be turned and adjusted to be switched between the folded position and the unfolded position. Accordingly, when the elastic folding plate is unfolded and the supporting plate 230 is in the unfolded position, the other end of the supporting plate 230 abuts against the inner side surfaces (i.e. the side surfaces facing the first barrel wall) of the two plate portions 222 of the elastic folding plate in the middle. Through the above design, the positioning device 200 provided by the present disclosure can optimize the positioning effect in the horizontal direction by using the supporting plate 230, and at the same time, can realize the support of the second positioning seat 220 in the unfolded state. In other embodiments, the supporting plate 230 may be replaced by other structures, such as a supporting rod, and the like, and the present embodiment is not limited thereto.
Further, as shown in fig. 1, 4 and 5, based on the design that the positioning device 200 includes the support plate 230, and based on the design that the second positioning seat 220 adopts an elastic folding plate, in the present embodiment, the two plate portions 222 of the elastic folding plate located in the middle are respectively provided with a first latch 2221 on one side surface facing the first cylinder wall. Accordingly, when the other end of the supporting plate 230 abuts against the two plate portions 222 of the elastic folding plate, the first latch 2221 is latched on the upper surface of the other end of the supporting plate 230, so as to prevent the supporting plate 230 from turning upwards. In other embodiments, the first latch 2221 may be provided on at least one of the two plate portions 222 of the elastic folding plate located at the middle portion. Moreover, in order to position the supporting plate 230 that is unfolded and supported by the elastic folding plate, other structures may also be adopted, for example, a positioning protrusion is disposed at the other end of the supporting plate 230, and a positioning groove matched with the positioning protrusion is disposed on the elastic folding plate, which is not limited by the present embodiment.
Further, as shown in fig. 1, 4 and 5, based on the design of the first latch 2221, in the present embodiment, the two plate portions 222 of the elastic folding plate located at the middle portion may be further provided with a second latch 2222 on one side surface facing the first cylinder wall. Accordingly, when the other end of the supporting plate 230 abuts against the two plate portions 222 of the elastic folding plate, the second latch 2222 is latched on the lower surface of the other end of the supporting plate 230, that is, the supporting plate 230 is positioned by the second latch 2222 and the first latch 2221 in a matching manner. It should be noted that the number of the first latches 2221 and the number of the second latches are not limited to be the same, and the opening positions of the first latches 2221 and the second openings are also not limited to the corresponding relationship in the vertical direction.
Further, as shown in fig. 4 and 5, based on the design of the support plate 230, in the present embodiment, the support plate 230 may preferably be designed to be integrated with the first positioning seat 210. On this basis, the end of the supporting plate 230 connected to the first positioning seat 210 can be movably connected to the bottom end of the cylinder of the first positioning seat 210 preferably through a groove structure 231.
