DETAILED DESCRIPTION

[0042] A safety railing of the utility model will be described in more detail below in conjunction with the accompanying drawings, wherein preferred embodiments of the utility model are shown. It should be understood that those skilled in the art can modify the utility model described herein while still achieving the beneficial effects of the utility model. Therefore, the following description should be understood as being widely known to those skilled in the art, and not as a limitation to the utility model.

[0043] The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the accompanying drawings are in very simplified form and in non-precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0044] like Figure 1-4 As shown, the embodiment of the utility model provides a convenient and practical safety railing, comprising: a foldable first railing unit, a foldable second railing unit and a connecting rod mechanism.

[0045] Specifically, one end of the first railing unit is rotatably mounted on the top side of the container 10, and the other end is slidably connected to one side of the second railing unit; one side of the second railing unit is parallel to the top side of the container 10, and the other side of the second railing unit is rotatably mounted on the top side of the container 10; one end of the connecting rod mechanism is fixedly connected to one end of the first railing unit, and the other end is rotatably connected to the second railing unit; the second railing unit, the first railing unit and the connecting rod mechanism are all located on the same side of the container 10.

[0046] The first railing unit, the second railing unit and the connecting rod mechanism form a railing unit. Preferably, a plurality of railing units may be provided, and the plurality of railing units are respectively provided on four sides of the container 10 and located at the top of the container 10 (i.e., the top side of the container 10). By providing a plurality of railing units, the application scope of the device can be expanded.

[0047] In this embodiment, the first railing unit includes: a first support column 11 and a first handrail bar 12 .

[0048] Specifically, one end of the first pillar 11 is rotatably installed on the top side of the container 10 and is fixedly connected to one end of the connecting rod mechanism; the other end of the first pillar 11 is rotatably connected to one end of the first handrail rod 12; the other end of the first handrail rod 12 is slidably connected to one side of the second railing unit; when the first railing unit and the second railing unit are in an open state, the first pillar 11 is perpendicular to the first handrail rod 12, and the first handrail rod 12 is parallel to one side of the second railing unit.

[0049] When the first pillar 11 folds downward toward the second railing unit or stretches upward (that is, the first railing unit and the second railing unit move toward or away from each other), the end of the first pillar 11 away from the container 10 rotates around the connection point between the first pillar 11 and the container 10.

[0050] In this embodiment, the second railing unit includes: a plurality of second pillars 21 and a second handrail 22 .

[0051] Specifically, one end of the second pillar 21 is rotatably mounted on the side wall of the second handrail rod 22, and the other end of the second pillar 21 is rotatably mounted on the top side of the container 10; the end of the second handrail rod 22 is slidably connected to the other end of the first handrail rod 12; when the first railing unit and the second railing unit are in an open state, the second handrail rod 22 is perpendicular to the second pillar 21 and parallel to the top side of the container 10; one of the side walls of the second pillar 21 adjacent to the first pillar 11 is rotatably connected to the other end of the connecting rod mechanism.

[0052] The length of the second handrail 22 may be greater than the length of the first handrail 12. The lengths of the first handrail 12 and the second handrail 22 may be set according to actual needs.

[0053] In this embodiment, a plurality of second pillars 21 may be provided with steel wire ropes 7 to improve the stability of the entire structure.

[0054] In this embodiment, continue to refer to Figure 1 and Figure 3 As shown, the connecting rod mechanism includes: a movable rod 31 and a connecting rod 32.

[0055] Specifically, one end of the movable rod 31 is fixedly connected to one end of the first pillar 11, and the other end of the movable rod 31 is rotatably connected to one end of the connecting rod 32; the other end of the connecting rod 32 is rotatably connected to a side wall of the second pillar 21 adjacent to the first pillar 11. By setting the connecting rod mechanism, the stability of the entire structure can be enhanced, and the movement of the second pillar 21 can be effectively transmitted to the first pillar 11, thereby realizing the synchronous movement of the first railing unit and the second railing unit.

[0056] In one embodiment, a predetermined spacing is reserved between the connection point between the connecting rod 32 and the second pillar 21 and the folding center of the second pillar 21. The predetermined spacing can be set according to actual conditions to ensure that the device is normally opened and folded. Among them, the folding center of the second pillar 21 includes the rotation point of the second pillar 21 and the side wall of the second handrail rod 22, and the rotation point of the second pillar 21 and the top side of the container 10. Therefore, the predetermined spacing is reserved between the connection point between the connecting rod 32 and the second pillar 21 and the rotation point of the side wall of the second pillar 21 and the second handrail rod 22, and the predetermined spacing is reserved between the connection point between the connecting rod 32 and the second pillar 21 and the rotation point of the second pillar 21 and the top side of the container 10.

[0057] In this embodiment, when the first railing unit and the second railing unit are in the open state, the angle between the movable rod 31 and the first pillar 11 is set to be larger than the angle between the line connecting the connection point between the movable rod 31 and the first pillar 11 to the connection point between the connecting rod 32 and the second pillar 21 and the first pillar 11, which can avoid the dead point phenomenon between the movable rod 31 and the connecting rod 32, that is, avoid the movable rod 31 and the connecting rod 32 from being on the same horizontal line.

[0058] Furthermore, the angle between the movable rod 31 and the first pillar 11 is less than 180 degrees, which can reduce the instability of the overall structure caused by excessive swinging of the first pillar 11 and the second pillar 21 due to excessive swinging of the movable rod 31, and help ensure the stability and reliability of the mechanism during operation.

[0059] In addition, combined Figure 4-Figure 6 As shown, this embodiment further includes a plurality of brackets 4 disposed on the side wall of the container 10. Specifically, one of the brackets 4 is located on the side of the first pillar 11, and another of the brackets 4 is located between adjacent second pillars 21. When the device is in a folded state, the first handrail bar 12 and the second handrail bar 22 can be located on the brackets 4 through the arrangement of the brackets 4, playing a supporting role, thereby improving the overall stability.

[0060] Preferably, the bracket 4 can be a U-shaped structure or an L-shaped structure, etc., and can be configured according to actual needs.

[0061] In addition, combined Figure 7 and Figure 8 As shown, this embodiment further includes a limit plate 5 disposed on the side wall of the container 10. Specifically, the first pillar 11 or the second pillar 21 can contact the first pillar 11 or the second pillar 21 when it is in a folded state and in an expanded state to a position perpendicular to the top side of the container 10, so as to limit the expansion range of the first pillar 11 or the second pillar 21.

[0062] In a specific example, for example, the limiting plate 5 is located on a side wall of the second support column 21 which is close to the end of the second handrail rod 22 and away from the first railing unit.

[0063] In one embodiment, the limiting plate 5 is an L-shaped structural plate, and the L-shaped structural plate is located on the side wall of the second pillar 21, which can prevent the second pillar 21 from moving in the reverse direction when falling down and folding.

[0064] Preferably, the present embodiment further comprises a control assembly connected to one of the second pillars 21. Specifically, the control assembly drives one of the second pillars 21 to fall down and fold toward the first railing unit, so as to drive the first railing unit to fall down and fold toward the second railing unit.

[0065] In this embodiment, combined with Fig. 9As shown, the control assembly includes: a connecting plate 61, a moving rod 62, a device plate 63 and a driving rod 64. Specifically, one end of the connecting plate 61 is connected to the second pillar 21, and the other end of the connecting plate 61 is rotatably connected to one end of the moving rod 62; the other end of the moving rod 62 is rotatably mounted on the device plate 63; the device plate 63 is rotatably mounted on the container 10; the driving rod 64 is rotatably mounted on the device plate 63, and the angle between the driving rod 64 and the moving rod 62 is between 90 and 180 degrees. By operating the driving rod 64, the device plate 63 is driven to rotate, and then the moving rod 62 is driven to move left and right, and then the connecting plate 61 is driven to rotate. The rotation of the connecting plate 61 can drive the second pillar 21 connected thereto to rotate, and under the linkage of the connecting rod mechanism, the second railing unit and the first railing unit move toward each other, thereby achieving folding.

[0066] In another embodiment, the limiting plate 5 includes a first folding plate and a second folding plate, and the control assembly includes: a ring handle is provided on the side wall of one of the second pillars 21 close to the end of the second handrail rod 22 and away from the first railing unit. Specifically, the first folding plate is rotatably connected to the second folding plate; the first folding plate is fixedly mounted on the side wall of the container 10; the side wall of the second folding plate is provided with a slot; when the second folding plate is perpendicular to the first folding plate, the second pillar 21 can be located in the slot, and the second pillar 21 can be limited by the slot. By rotating the second folding plate so that the second folding plate is parallel to the first folding plate, and then holding the ring handle and the second handrail rod 22, the second handrail rod 22 is folded down, and the first railing unit and the second railing unit are driven to move toward each other under the linkage of the connecting rod mechanism, thereby achieving folding.

[0067] In a specific example, combining Figure 10-11 As shown, the first pillar 11 and the first handrail rod 12, the second pillar 21 and the second handrail rod 22 can be rotatably connected through a connecting member. The connecting member includes an annular fixing clamp 91 with an opening, a pair of connecting plates 92, a plurality of nuts 93 and a bolt 94. Taking the connection between the second handrail rod 22 and the second pillar 21 as an example, the second handrail rod 22 passes through the annular fixing clamp 91, and the two ends of the annular fixing clamp 91 (the ends are located at the position with an opening) are respectively connected to the pair of connecting plates 92; the end of the second pillar 21 away from the container 10 is located between the pair of connecting plates 92, and the second pillar 21 passes through one of the nuts 93, one of the connecting plates 92, the first pillar 11, another connecting plate 92 and another nut 93 through a bolt 94 in sequence, and can be rotatably connected to the second handrail rod 22. The bolt 94 is threadedly connected to the nut 93, and the bolt 94 is rotatably connected to the first pillar 11.

[0068] Preferably, a gasket may be provided between the connecting piece 92 and the nut 93 to enhance friction and stability.

[0069] In one embodiment, a plurality of support plates 100 may be provided at the inner top of the container 10, and the first pillar 11 and the second pillar 21 may both be L-shaped pillars, the corners of the L-shaped pillars are fixedly connected to the movable rod 31, and one end away from the first handrail rod 12 and the second handrail rod 22 extends to the inner top of the container 10 and passes through the plurality of support plates 100. The side wall of the connection portion between the L-shaped pillar and the support plate 100 is provided with a baffle 8, and the baffle 8 is located between the plurality of support plates 100. By providing the baffle 8, the L-shaped pillar can be prevented from being pulled out in the container 10.

[0070] In one embodiment, in combination Figure 1 , Figure 4 and Fig. 9 As shown, the container 10 can be divided into a front end 101 and a rear end 102. The control assembly is arranged at the rear end 102 of the container 10, and the first railing unit is arranged at the front end 101 of the container 10, so that the staff can enter the top of the container 10 from the rear end 102. In addition, the second pillar 21 near the rear end 102 is connected to the control assembly, and the limit plate 5 is arranged on the side wall of the second pillar 21 near the rear end 102.

[0071] In this embodiment, when it is necessary to open the door, the control component can be manipulated, for example, by rotating the connecting plate 61, the second pillar 21 can be driven to rotate upward away from the first railing unit. At the same time, driven by the connecting rod mechanism, the first pillar 11 can be driven to rotate upward away from the second railing unit, and the first handrail bar 12 can slide away from the second handrail bar 22 and move upward under the movement of the first pillar 11, thereby achieving overall opening.

[0072] When folding is required, the second pillar 21 is driven to rotate downward in the direction close to the first railing unit through the reverse movement of the connecting plate 61. At the same time, driven by the connecting rod mechanism, the first pillar 11 is driven to rotate downward in the direction close to the second railing unit. The first handrail bar 12 slides in the direction close to the second handrail bar 22 and moves downward under the movement of the first pillar 11, thereby realizing overall folding.

[0073] In summary, the safety railing proposed by the utility model has the following advantages:
