Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] See below. Figures 1-13 This invention provides a detailed description of a multi-purpose, expandable, and retractable protective shed / box device.

[0033] The multi-purpose expandable and retractable protective canopy box device of this utility model includes a fixed box assembly as the main body, and a sliding box assembly installed thereon, and also includes a double C groove 11 for connecting the internal side plate of the protective canopy box device and the side plate between the protective canopy box devices.

[0034] like Figures 1-2 As shown, the fixed box assembly includes a fixed box frame consisting of a support column 6, a first upper crossbar 3, a first lower crossbar 4, a fixed top plate 1, a fixed bottom plate 2, and a horizontal connecting rod 5. It also includes a first side plate 8 located on the left and right sides of the fixed box frame and a mezzanine side plate 7 on the front and rear sides, which are connected to the fixed box frame by hinges and telescopic hydraulic struts 12. A lifting lug 10 is provided on the top of the support column 6. A pull-out side plate 9 is embedded in the mezzanine side plate 7. The two ends of the first lower crossbar 4 are provided with fixed limiting holes 13.

[0035] The purpose of this structure is to fix the container assembly to the standard container size when it is not unfolded. The first side panel 8 and the mezzanine side panel 7 can be raised to a horizontal state by hinges and telescopic hydraulic struts 12. The removable side panel 9 can be pulled out from the mezzanine side panel 7 so that it is flush with the length of the first side panel 8 after it is raised. The removable side panel 9 and the first side panel 8 can be fixed by double C grooves 11 after they are unfolded.

[0036] like Figure 13 As shown, the double C-groove 11 is a separate component with outward C-shaped grooves at both ends and a certain height difference between the two C-shaped grooves. The two C-shaped grooves are connected by a plate with a slope. The double C-shaped grooves can be connected to the sides of the first side plate 8 and the pull-out side plate 9 respectively, making the connection more stable and covering the gaps to prevent rain and air leakage.

[0037] like Figure 3 As shown, the mezzanine side panel 7 hides the upper panel and reveals its internal structure. Its limiting guide rail allows the pull-out side panel 9 to move along a fixed trajectory in the mezzanine side panel 7 and controls the maximum length of its pull-out, so that the pull-out side panel 9 is flush with the length of the first side panel 8 after it is fully pulled out.

[0038] like Figures 4-7 As shown, the sliding box assembly includes a sliding box frame composed of a supporting column 6, a second upper crossbar 17, a second lower crossbar 18, and a sliding top plate 16. It also includes a second side plate 19 fixed to the front and rear sides of the sliding box frame by hinges and a telescopic hydraulic strut 12, and a lifting lug 10 set on the top of the supporting column 6. The second lower crossbar 18 is provided with a plurality of fixed limiting holes 13 at intervals, and the lower surface of its two ends is provided with lower guide pulleys 21. The lower surface of the second upper crossbar 17 is provided with three equally distributed upper guide pulleys 20.

[0039] The purpose of this structure is that the second side plate 19 of the sliding box assembly can be raised to a horizontal state by means of a hinge and a telescopic hydraulic strut 12; the lower guide pulley 21 on the lower surface of the second lower crossbar 18 slides on the ground to separate the sliding box assembly from the fixed box assembly; the guide pulley 20 on the upper surface of the second upper crossbar 17 allows the sliding box assembly to slide on the fixed top plate 1 of the fixed box assembly.

[0040] like Figure 8 As shown, when the sliding box assembly separates from the fixed box assembly and unfolds, the second side plate 19 and the sliding top plate 16 are both slightly higher than the interlayer side plate 7, and the interlayer side plate 7 is slightly higher than the first side plate 8. After unfolding, the first side plate 8, which is closer to the sliding direction of the sliding box assembly, is retracted into the bottom of the sliding top plate 16. The first side plate 8 in the opposite direction unfolds outward to a horizontal state and is connected to the pull-out side plate 9 through the double C groove 11. The place where the second side plate 19 overlaps with the interlayer side plate 7 can provide a certain degree of shielding to the ground. It is also possible to choose whether to extend the pull-out side plate 9 into the interlayer side plate 7 according to the actual situation.

[0041] like Figures 9-10 As shown, when the sliding box assembly and the fixed box assembly are retracted, the fixing limit holes 13 at both ends of the two align, and the pins 14 can pass through the first lower crossbar 4 and the second lower crossbar 18, and be fixed by the pin piece 15; when the sliding box assembly and the fixed box assembly are separated and unfolded to the maximum extent, the rightmost end of the sliding box assembly and the leftmost end of the fixed box assembly align with the fixing limit hole 13, and are fixedly connected by the pins 14 and the pin piece 15 to prevent them from separating from each other.

[0042] like Figures 11-12As shown, since the second side plate 19 of the sliding box assembly is slightly higher than the first side plate 8 of the fixed box assembly after unfolding, the fixed box assembly and the sliding box assembly can be arranged end to end during lateral expansion, and the second side plate 19 can be connected to the shorter side of the first side plate 8 through a double C groove 11 of the corresponding size; during longitudinal expansion, the fixed box assembly and the sliding box assembly can be arranged in a staggered manner, and the second side plate 19 can be connected to the longer side of the first side plate 8 through a double C groove 11 of the corresponding size. This ensures that the unfolding process of the fixed box assembly and the sliding box assembly does not interfere with each other during expansion.

[0043] Below, refer to Figures 1 to 13 Based on the above description of structural features, the specific installation and usage of the multi-purpose expandable and retractable protective canopy box device of this utility model will be described in detail:

[0044] 1. Based on the site layout and construction needs, select a suitable location on a leveled site and use a tower crane or truck crane to lift and place any number of protective canopy boxes.

[0045] 2. Pull out the pins 14 and 15 that connect the sliding housing assembly and the fixed housing assembly, push the sliding housing assembly to slide on the fixed housing assembly, and separate it from the fixed housing assembly until the fixing limit hole 13 on the second lower crossbar 18 of the sliding housing assembly is aligned with the fixing limit hole 13 on the first lower crossbar 4 of the fixed housing assembly.

[0046] 3. Insert the pin 14 into the fixed limiting hole 13 that overlaps with the sliding box assembly and the fixed box assembly, and fix it with the pin piece 15 so that the fixed box assembly and the sliding box assembly are connected and fixed to each other.

[0047] 4. Unfold the second side plates 19 on the front and rear sides of the sliding box assembly upwards.

[0048] 5. Unfold the sandwich side panels 7 on the front and rear sides and the first side panels 8 on the left and right sides of the fixed box assembly upwards.

[0049] 6. Pull out the removable side panel 9, with the length of the pull-out panel being flush with the length of the first side panel 8 after it is unfolded, and insert the double C groove 11 into the gap between the removable side panel 9 and the first side panel 8; if several protective shed boxes need to be combined with each other, wait until all the protective shed boxes are unfolded, and then connect the first side panel 8 and the second side panel 19 of each box with different sizes of double C groove 11.

[0050] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any transformations or substitutions that can be understood by those skilled in the art within the technical scope disclosed in this utility model should be included within the scope of this utility model.
