[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this technical field without creative work are within the scope of protection of the utility model.
[0024] See also Figure 1-6The foldable steel bar shed of this embodiment includes a frame 1 and two exhibition sheds 2. A plurality of folding hinges 3 are installed between the frame 1 and the exhibition shed 2. The folding hinges 3 include a fixed frame bar 31 installed on the side wall of the frame 1 and a movable frame bar 33 installed on the bottom surface of the exhibition shed 2. One end of the movable frame bar 33 is fixedly connected to a first shaft 32. Both ends of the first shaft 32 are rotatably connected to the fixed frame bar 31. The lower end inner wall of the fixed frame bar 31 is rotatably connected to a second shaft 34. Both ends of the second shaft 34 pass through the outside of the fixed frame bar 31 and are fixedly connected to two adjustment bars. 35, an adjustment groove 36 is formed through the side wall of the movable frame bar 33, a sliding rod 37 is fixedly connected between the two adjustment bars 35, and the sliding rod 37 is slidably connected in the adjustment groove 36, a third shaft 38 is fixedly connected to the inner wall of the movable frame bar 33, a top piece 39 for limiting the sliding rod 37 is rotatably connected to the outer wall of the third shaft 38, a torsion spring 310 for applying torsion force to the top piece 39 is installed on the outer wall of the third shaft 38, and a power assist unit 4 for assisting the rotation of the exhibition shed 2 is installed between the movable frame bar 33 and the fixed frame bar 31.
[0025] like Figure 1-5 As shown, the steel bar shed in the utility model is similar to the existing steel bar shed structure. The main improvement of the utility model is that the steel bar shed is foldable, convenient for unfolding and folding, convenient for transportation and convenient for transfer; the exhibition shed 2 in the utility model is supported on the side wall of the frame 1 by the folding hinge 3, and the folding hinge 3 on one side of the frame 1 is not less than two. When it is necessary to fold and store the exhibition shed 2, the top piece 39 is pressed to rotate the top piece 39 along the third axis 38 as the axis, thereby eliminating the obstruction of the top piece 39 to the slide bar 37. At this time, the slide bar 37 can slide in the adjustment groove 36, and the slide bar 37 drives the adjustment bar 35 to rotate along the second axis 34 as the axis, and the movable frame bar 33 rotates along the first axis 32, so that the exhibition shed 2 is turned down to the side of the frame 1 for storage. When it is necessary to unfold the exhibition shed 2 for use, the exhibition shed 2 is lifted up. The movable frame bar 33 is rotated accordingly, thereby driving the adjustment slot 36 and the sliding rod 37 to slide. The sliding rod 37 contacts the top piece 39 and squeezes the top piece 39 to rotate downward until the sliding rod 37 slides over the top piece 39. At this time, the fixed frame bar 31 and the movable frame bar 33 are vertical. Driven by the torsion spring 310, the top piece 39 is rotated, and the inner wall of the movable frame bar 33 at one end of the top piece 39 is abutted. The top piece 39 also blocks the sliding rod 37, making the sliding rod 37 unable to move, thereby fixing the movable frame bar 33 and keeping the exhibition shed 2 in the expanded state. The overall structure is simple, and the folding hinge 3 is used to realize the expansion and contraction of the exhibition shed 2, so that when the steel shed is transported, the exhibition shed 2 can be stored, reducing the occupied space and facilitating transportation. At the same time, the stability is better during the transfer, and the steel shed will not be damaged, thereby improving practicality.
[0026] like Figure 3 , 4As shown, the folding hinge 3 also includes a clearance opening 311, which corresponds to the second axis 34; when the exhibition tent 2 is folded, the movable frame bar 33 rotates into the fixed frame bar 31, and the clearance opening 311 is sleeved outside the second axis 34, so that the exhibition tent 2 can be folded closer to the frame 1, further reducing the occupied area.
[0027] like Figure 4 As shown, the number of third shafts 38 fixed on the inner wall of the movable frame bar 33 is two, the top pieces 39 and the torsion springs 310 on the two third shafts 38 are oppositely arranged, and the side wall of the fixed frame bar 31 is provided with a control opening 315 corresponding to the top piece 39; when the exhibition tent 2 is opened and stored, the two top pieces 39 can block and restrict the sliding bar 37 to achieve the restriction of the exhibition tent 2, and when the movable frame bar 33 is rotated into the fixed frame bar 31, there is enough space in the fixed frame bar 31 to make way for the top piece 39, and the top piece 39 will not squeeze the side wall of the fixed frame bar 31, and when the exhibition tent 2 needs to be opened, the top piece 39 restricted by the sliding bar 37 can be rotated through the control opening 315 to cancel the restriction, thereby further improving the practicality and stability.
[0028] like Figure 4 As shown, the folding hinge 3 also includes a slot 314 opened at the ends of the two top pieces 39 and a slide groove 312 opened on the outer wall of the movable frame bar 33, and a hook 313 is slidably connected in the slide groove 312, and the side end section of the hook 313 is an I-shaped structure, and the hook 313 is movably engaged with the slot 314; after the top piece 39 is turned to cancel the restriction on the slide rod 37, the hook 313 can be moved so that the hook 313 is hung in the slide groove 312, thereby blocking the top piece 39 and preventing the top piece 39 from rotating, thereby facilitating a single person to control the multiple folding hinges 3 on the side wall of the frame 1 to rotate the exhibition shed 2.
[0029] like Figure 3-6As shown, the power-assisting unit 4 includes an extension frame bar 41 fixedly connected to the lower end of the fixed frame bar 31 and a fourth shaft 42 rotatably connected to the movable frame bar 33, the outer wall of the fourth shaft 42 is fixedly connected to a transmission rod 43, the side wall of the extension frame bar 41 is provided with a limiting groove 44, the other end of the transmission rod 43 is rotatably connected to a fifth shaft 45, the fifth shaft 45 is slidably connected to the inner wall of the limiting groove 44, the side wall of the extension frame bar 41 is fixedly connected to the side wall of the frame 1, the upper end inner wall of the extension frame bar 41 is fixedly connected to a baffle 46, a stabilizing rod 47 is fixedly connected between the inner bottom surface of the extension frame bar 41 and the baffle 46, the stabilizing rod 47 runs through the fifth shaft 45, the fifth shaft 45 is slidably connected to the outer wall of the stabilizing rod 47, and the outer wall of the stabilizing rod 47 is slidably connected to the fifth shaft 45. The outer wall of the stabilizing rod 47 is sleeved with a booster spring 49, and the two ends of the booster spring 49 are respectively abutted against the bottom surface of the booster block 48 and the inner bottom surface of the extended frame bar 41; when the exhibition tent 2 rotates, the movable frame bar 33 drives the transmission rod 43 to rotate along the fourth axis 42 as the axis, and the transmission rod 43 drives the fifth axis 45 to slide in the limiting groove 44, and the fifth axis 45 slides on the outer wall of the stabilizing rod 47. The fifth axis 45 drives the booster spring 49 to be compressed through the booster block 48, or the booster spring 49 is used for assistance. By using the booster spring 49, the exhibition tent 2 can be assisted to unfold through the booster spring 49 when it is unfolded, and can be cached through the booster spring 49 when it is folded, so as to facilitate the unfolding and folding operation of the exhibition tent 2 and facilitate use.
[0030] like Figure 5 , 6 As shown, there are two stabilizing rods 47, the fifth shaft 45 is slidably connected to the two stabilizing rods 47, and the stabilizing rods 47 are respectively located at both ends of the fifth shaft 45; the assist springs 49 outside the two stabilizing rods 47 cooperate with the stop blocks 48 to stabilize the fifth shaft 45 and apply elastic force to improve stability.
[0031] like Figure 6 As shown, the upper end surface of the stopper 48 is provided with an arc opening 410, and the arc opening 410 is sleeved on the outer wall of the fifth shaft 45; the arc opening 410 can be sleeved outside the fifth shaft 45 to improve the stability of the elastic force applied by the assist spring 49 to the fifth shaft 45, while reducing wear.
[0032] In this embodiment, the implementation steps are as follows: when the exhibition tent 2 needs to be folded and stored, one of the top pieces 39 close to the first axis 32 is pressed to make the top piece 39 rotate along the third axis 38 as the axis, thereby removing the blocking of the slide bar 37 by the top piece 39. At this time, the slide bar 37 can slide in the adjustment groove 36, and the slide bar 37 drives the adjustment bar 35 to rotate along the second axis 34 as the axis, and makes the movable frame bar 33 rotate along the first axis 32, and the movable frame bar 33 drives the transmission rod 43 to rotate along the fourth axis 42 as the axis. The transmission rod 43 drives the fifth shaft 45 to slide in the limiting groove 44, and the fifth shaft 45 slides on the outer wall of the stabilizing rod 47. The fifth shaft 45 drives the assisting spring 49 to be compressed through the stop block 48, and the assisting spring 49 buffers the exhibition shed 2. The movable frame bar 33 rotates into the fixed frame bar 31, and the clearance opening 311 is sleeved outside the second shaft 34. The sliding rod 37 pushes open and slides over another top piece 39. Under the drive of the torsion spring 310, one end of the top piece 39 away from the first shaft 32 The top piece 39 abuts against the inner wall of the movable frame bar 33, and blocks the slide bar 37, so as to realize the folding and fixing of the exhibition tent 2; when the exhibition tent 2 needs to be unfolded for use, the top piece 39 that restricts the slide bar 37 is pressed through the control port 315, so that the top piece 39 cancels the restriction on the slide bar 37, and then the exhibition tent 2 is lifted up, and the assist spring 49 provides elastic force to assist the rotation of the exhibition tent 2, and the movable frame bar 33 rotates accordingly, thereby driving the adjustment slot 36 and the slide bar 37 to slide, and the slide bar 37 is lifted up. 7 contacts with the top piece 39 close to the first shaft 32 and presses the top piece 39 to rotate downward until the slide bar 37 slides over the top piece 39. At this time, the fixed frame bar 31 and the movable frame bar 33 are vertical. Driven by the torsion spring 310, the top piece 39 rotates, and one end of the top piece 39 abuts against the inner wall of the movable frame bar 33. The top piece 39 blocks the slide bar 37, making it unable to move, thereby fixing the movable frame bar 33 and keeping the exhibition shed 2 in the unfolded state.
[0033] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here.
