DETAILED DESCRIPTION

[0029] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0030] In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0031] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0032] In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0033] In the present application, unless otherwise clearly specified and limited, a first feature being “above” or “below” a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being “above”, “above”, and “above” a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being “below”, “below”, and “below” a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0034] In the production process of medicines, turnover boxes are usually used to hold materials, and then the turnover boxes are grouped and stacked on a mobile platform for transportation to achieve material turnover.

[0035] During transportation, if there are slopes or bumpy roads, the turnover boxes at the rear may easily lose support and fall. The fallen turnover boxes may easily be damaged or even injure people around them. Therefore, there is a major safety hazard and the cost of scrapping the turnover boxes is increased.

[0036] In addition, in order to reduce safety hazards and scrap costs, two transport personnel are usually used to transfer materials. One person pulls the mobile platform in front, and the other person holds the turnover box with both hands in the back, which increases labor costs.

[0037] like Figure 1 and Figure 2 As shown, in order to solve the above-mentioned technical problems, on the first aspect, an embodiment of the present application provides a protective structure 100, which relates to the field of pharmaceutical production technology and is mainly used in a turnover device 1000 for fixing four adjacent turnover boxes 200 in the turnover device 1000.

[0038] like Figures 2 to 4 As shown, the protection structure 100 provided in this embodiment includes a first U-shaped claw 110 and a second U-shaped claw 120 connected to each other.

[0039] Among them, one end of the first U-shaped claw 110 is used to penetrate the corner of the opening 210 of the first turnover box 200 among the four adjacent turnover boxes 200, and the other end of the first U-shaped claw 110 is used to penetrate the corner of the opening 210 of the second turnover box 200 among the four adjacent turnover boxes 200. One end of the second U-shaped claw 120 is used to penetrate the corner of the opening 210 of the third turnover box 200 among the four adjacent turnover boxes 200, and the other end of the second U-shaped claw 120 is used to penetrate the corner of the opening 210 of the fourth turnover box 200 among the four adjacent turnover boxes 200.

[0040] It is understandable that when the protective structure 100 provided in this embodiment is used, one end of the first U-shaped claw 110 is inserted into the corner of the opening 210 of the first turnover box 200 among the four adjacent turnover boxes 200, and the other end of the first U-shaped claw 110 is inserted into the corner of the opening 210 of the second turnover box 200 among the four adjacent turnover boxes 200. On this basis, one end of the second U-shaped claw 120 is inserted into the corner of the opening 210 of the third turnover box 200 among the four adjacent turnover boxes 200, and the other end of the second U-shaped claw 120 is inserted into the corner of the opening 210 of the fourth turnover box 200 among the four adjacent turnover boxes 200. In this way, the four adjacent turnover boxes 200 are fixed, and the possibility of the turnover boxes 200 tipping over during transportation is reduced, thereby reducing safety hazards and scrapping costs.

[0041] In one embodiment, one end of the first U-shaped claw 110 is also used to abut the bottom of the first turnover box 200 among the four adjacent turnover boxes 200, the other end of the first U-shaped claw 110 is also used to abut the bottom of the second turnover box 200 among the four adjacent turnover boxes 200, one end of the second U-shaped claw 120 is also used to abut the bottom of the third turnover box 200 among the four adjacent turnover boxes 200, and the other end of the second U-shaped claw 120 is also used to abut the bottom of the fourth turnover box 200 among the four adjacent turnover boxes 200.

[0042] It is understandable that when the protective structure 100 provided in this embodiment is used, one end of the first U-shaped claw 110 can be abutted against the bottom of the first turnover box 200 among the four adjacent turnover boxes 200, and the other end of the first U-shaped claw 110 can be abutted against the bottom of the second turnover box 200 among the four adjacent turnover boxes 200. At the same time, one end of the second U-shaped claw 120 can be abutted against the bottom of the third turnover box 200 among the four adjacent turnover boxes 200, and the other end of the second U-shaped claw 120 can also be abutted against the bottom of the fourth turnover box 200 among the four adjacent turnover boxes 200. In this way, the two ends of the first U-shaped claw 110 and the two ends of the second U-shaped claw 120 are set deep into the turnover box 200, so that there is a greater grip between the four adjacent turnover boxes 200, thereby further reducing the possibility of the turnover box 200 tipping over during transportation.

[0043] Of course, for the above embodiment, both ends of the first U-shaped claw 110 and both ends of the second U-shaped claw 120 may also be spaced apart from the bottom of the turnover box 200, and no specific limitation is made here.

[0044] like Figure 3 and Figure 4As shown, in one embodiment, the first U-shaped claw 110 includes a first claw portion 111 and a second claw portion 112 connected to each other, the first claw portion 111 is used to penetrate the corner of the opening 210 of the first turnover box 200 among the four adjacent turnover boxes 200, and the second claw portion 112 is used to penetrate the corner of the opening 210 of the second turnover box 200 among the four adjacent turnover boxes 200. The second U-shaped claw 120 includes a third claw portion 121 and a fourth claw portion 122, the third claw portion 121 is used to penetrate the corner of the opening 210 of the third turnover box 200 among the four adjacent turnover boxes 200, and the fourth claw portion 122 is used to penetrate the corner of the opening 210 of the fourth turnover box 200 among the four turnover boxes 200, and the connection between the first claw portion 111 and the second claw portion 112 is fixedly connected to the connection between the third claw portion 121 and the fourth claw portion 122.

[0045] It is understandable that when the protective structure 100 provided in this embodiment is used, the first claw portion 111 is inserted into the corner of the opening 210 of the first turnover box 200 among the four adjacent turnover boxes 200, and the second claw portion 112 is inserted into the corner of the opening 210 of the second turnover box 200 among the four adjacent turnover boxes 200. At the same time, the third claw portion 121 is inserted into the corner of the opening 210 of the third turnover box 200 among the four adjacent turnover boxes 200, and the fourth claw portion 122 is inserted into the corner of the opening 210 of the fourth turnover box 200 among the four turnover boxes 200. On this basis, the connection between the first claw portion 111 and the second claw portion 112 is fixedly connected to the connection between the third claw portion 121 and the fourth claw portion 122. In this way, the first claw portion 111 , the second claw portion 112 , the third claw portion 121 and the fourth claw portion 122 can support each other, thereby providing sufficient gripping force for four adjacent turnover boxes 200 to reduce the possibility of the turnover boxes 200 tipping over.

[0046] Furthermore, a connection between the first clamping claw portion 111 and the second clamping claw portion 112 is welded to a connection between the third clamping claw portion 121 and the fourth clamping claw portion 122 .

[0047] In this embodiment, since welding is used to fix the connection between the first claw portion 111 and the second claw portion 112 and the connection between the third claw portion 121 and the fourth claw portion 122, the manufacturing of the protective structure 100 is more convenient and quick, thereby reducing the manufacturing cost of the protective structure 100.

[0048] Of course, for the above embodiment, the connection between the first claw portion 111 and the second claw portion 112 and the connection between the third claw portion 121 and the fourth claw portion 122 can also be fixedly connected by screw connection, and no specific limitation is made here.

[0049] Furthermore, the first U-shaped claw 110 also includes a first reinforcement portion, which is respectively connected to the first claw portion 111 and the second claw portion 112, and the second U-shaped claw 120 also includes a second reinforcement portion, which is respectively connected to the third claw portion 121 and the fourth claw portion 122.

[0050] Exemplarily, the first reinforcement portion and the second reinforcement portion may be reinforcement ribs, reinforcement plates, reinforcement rods, etc.

[0051] In this embodiment, since the first reinforcement portion and the second reinforcement portion have higher structural strength, when the first U-shaped claw 110 and the second U-shaped claw 120 tend to deform during transportation, the first reinforcement portion and the second reinforcement portion can absorb the stress generated by the deformation, so that the first U-shaped claw 110 and the second U-shaped claw 120 maintain their original shape, thereby improving the structural strength and structural stability of the protective structure 100, thereby further reducing the possibility of tipping over of the turnover box 200.

[0052] In one embodiment, the first U-shaped claw 110 and the second U-shaped claw 120 are respectively made of stainless steel in one piece.

[0053] It should be noted that according to the definition in GB / T20878-2007, stainless steel is steel with stainlessness and corrosion resistance as its main characteristics, and a chromium content of at least 10.5% and a carbon content of no more than 1.2%.

[0054] In this embodiment, since the first U-shaped claw 110 and the second U-shaped claw 120 are respectively made of stainless steel in one piece, the possibility of rusting of the protective structure 100 can be effectively reduced, thereby extending the service life of the protective structure 100.

[0055] In one embodiment, anti-slip portions are respectively provided along the surface of the first U-shaped claw 110 and the surface of the second U-shaped claw 120 , and the anti-slip portions are used to abut against the inner side wall of the turnover box 200 .

[0056] Exemplarily, the anti-slip portion is one of a silicone layer, a rubber layer and an anti-slip pattern.

[0057] In this embodiment, anti-slip portions are respectively provided along the surface of the first U-shaped claw 110 and the surface of the second U-shaped claw 120, and the anti-slip portions are abutted against the inner wall of the turnover box 200 when the protective structure 100 is used. In this way, the possibility of the first U-shaped claw 110 and the second U-shaped claw 120 detaching from the turnover box 200 during the transportation of the turnover box 200 can be reduced, so that the four adjacent turnover boxes 200 have a greater grip on each other.

[0058] Furthermore, the anti-slip portion is used to contact or line-contact with the inner wall surface of the turnover box 200 .

[0059] In this embodiment, compared with the point contact method, the anti-slip portion abuts against the inner wall of the turnover box 200 in a surface contact or line contact manner, which can make the first U-shaped claw 110 and the second U-shaped claw 120 grip the turnover box 200 more firmly and stably, so that the four adjacent turnover boxes 200 have a greater grip on each other.

[0060] like Figure 1 and Figure 3 As shown, in the second aspect, the embodiment of the present application provides a turnover device 1000, including a mobile platform 300, multiple groups of turnover boxes 200 and the protective structure 100 mentioned in any of the above embodiments, multiple groups of turnover boxes 200 are arranged on the mobile platform 300 in a rectangular array, and each group of turnover boxes 200 includes multiple turnover boxes 200 stacked and placed along the height direction of the mobile platform 300. The protective structure 100 is provided with multiple turnover boxes 200, and among the multiple turnover boxes 200 at the highest stack, every four adjacent turnover boxes 200 are fixed by one protective structure 100.

[0061] Exemplarily, the mobile platform 300 includes a platform body 310 and rollers 320 , a plurality of groups of turnover boxes 200 are arranged on the platform body 310 in a rectangular array, and the rollers 320 are rotatably arranged on a side of the platform body 310 away from the turnover boxes 200 .

[0062] In the present embodiment, since every four adjacent turnover boxes 200 in the highest stack are fixed by a protective structure 100, the multiple groups of turnover boxes 200 can have a certain grip on each other, thereby reducing the risk of the turnover boxes 200 tipping over during the transportation of the turnover boxes 200 by the mobile platform 300.

[0063] At the same time, since the possibility of the turnover box 200 tipping over is effectively reduced, only one transporter is required to pull the mobile platform 300 in front to independently complete the transportation of materials, thereby reducing the labor cost by 50%.

[0064] It can be understood that since the turnover device 1000 provided in this embodiment has the protective structure 100 in any of the above embodiments, it has all the beneficial effects of the protective structure 100, which will not be listed one by one here.

[0065] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0066] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present application.
