Description

Technical Field

[0001] This utility model relates to the field of concrete storage technology, and in particular to a concrete storage device. Background Technology

[0002] Concrete is a general term for engineering composite materials in which aggregates are bound together by cementing materials. When dry concrete comes into contact with water, the main components of cement (such as tricalcium silicate and dicalcium silicate) undergo a silicate hydration reaction, producing cementitious substances such as hydrated calcium silicate. These substances gradually fill the voids between cement particles, causing the cement paste to gradually harden and increase its strength. Concrete reacting with water before storage can easily affect its subsequent normal use; therefore, a convenient and protective storage device is needed for concrete. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a concrete storage device that effectively solves the deficiencies of the prior art.

[0004] The purpose of this utility model is achieved through the following technical solution: a concrete storage device, including two bottom frames, a first rotating shaft rotatably connected to the joint of the bottom frames, the bottom frames being rotatably connected through the first rotating shaft, a folding sleeve fixedly connected to the outer side of each bottom frame, a second rotating shaft rotatably connected to the inner side of each bottom frame, a rotating frame rotatably connected to the bottom frame through the second rotating shaft, one end of the folding sleeve being fixedly connected to the side of the rotating frame, and a protective film fixedly connected between the two sides of the bottom frame and the rotating frame.

[0005] Optionally, the folding sleeve is in an arc shape when extended, and the two sides of the folding sleeve are combined to form a semi-cylindrical shape. The material of the folding sleeve is polytetrafluoroethylene.

[0006] The above technical solution involves setting a folding sleeve between the bottom frame and the rotating frame. When the rotating frame is rotated to a vertical position, the folding sleeve can be unfolded into a semi-cylindrical shape, thereby protecting the concrete stored below from rain and reducing the possibility of damage and deterioration of the concrete during storage. The folding sleeve made of polytetrafluoroethylene has excellent corrosion resistance and high temperature resistance, and can be used stably in hot environments to provide protection.

[0007] Optionally, the rotating frame is made of magnetite, and the magnetic properties of the mating surfaces of the rotating frame are opposite.

[0008] The above technical solution is adopted: by setting the material of the rotating frame to magnet, it can automatically attract and fix under the action of magnetism when it is attached, thereby keeping the folding sleeve and protective film in the unfolded state, thus protecting the concrete stored inside. In addition, the device can be folded into a smaller volume when not in use, making it convenient for storage and carrying.

[0009] Optionally, the protective film is fan-shaped, and the material of the protective film is a transparent polycarbonate film.

[0010] The above technical solution is adopted: by setting protective films on both sides of the folding sleeve, the storage device is protected on both sides, thereby fully covering and protecting the stored concrete. The polycarbonate transparent film has excellent corrosion resistance and is transparent, which makes it easy to observe the storage condition of the concrete inside. When not in use, it can be folded between the bottom frame and the rotating frame for easy carrying and storage.

[0011] Optionally, a torsion spring is fitted to each end of the second rotating shaft. The torsion of the torsion spring is such that the rotating frame and the bottom frame merge together. The torsion of the torsion spring is less than the magnetic force between the two rotating frames.

[0012] The above technical solution is adopted: by setting a torsion spring on the second rotating shaft, when the two rotating frames are not merged, the rotating frames can automatically rotate and merge with the bottom frame under the torsion of the torsion spring, thereby folding and shrinking the folding sleeve and the protective sleeve, so that the device can maintain a stable state in the folded state, limiting the torsion of the torsion spring, and avoiding its torsion affecting the unfolding of the storage device when the rotating frames are merged.

[0013] Optionally, the weight of the base frame is greater than the torque of the torsion spring, and the second pivot is located at the bottom of the junction of the two base frames.

[0014] The above technical solution is adopted: by setting a second pivot between the two bottom frames, when the rotating frame and the bottom frame are merged, the bottom frame can be rotated again to merge the two bottom frames, further reducing the space occupied by the storage state in the retracted state, making it convenient for storage and carrying. Limiting the weight of the bottom frame can prevent the bottom frame from tilting up due to the torque of the torsion spring when the rotating frame is merged and fixed.

[0015] Optionally, storage slots are fixedly connected to both sides of the top of the bottom frame, and the length of the storage slots is adapted to the width of the protective film.

[0016] The above technical solution is adopted: by setting storage grooves on both sides of the bottom frame, when the rotating frame and the bottom frame are merged and retracted, the protective film 6 can be pressed and retracted into the storage groove 8, which provides a protective effect for the protective film 6.

[0017] This utility model has the following advantages: 1. This concrete storage device features a folding sleeve between the bottom frame and the rotating frame. When the rotating frame is rotated to a vertical position, the folding sleeve unfolds into a semi-cylindrical shape, thus protecting the concrete stored below from rain and reducing the possibility of damage or deterioration during storage. The folding sleeve, made of polytetrafluoroethylene (PTFE), has excellent corrosion resistance and high-temperature resistance, enabling stable use and protection in hot environments. By using a magnet as the material for the rotating frame, it automatically adheres and fixes itself under magnetic attraction when in contact with the frame, keeping the folding sleeve and protective film in the unfolded state, thereby protecting the concrete stored inside. Furthermore, the device can be folded into a smaller volume when not in use, making it convenient for storage and transport.

[0018] 2. This concrete storage device, by setting protective films on both sides of the folding sleeve, provides comprehensive protection for the stored concrete. The transparent polycarbonate film has excellent corrosion resistance and is made of transparent material, making it easy to observe the storage status of the concrete inside. When not in use, it can be retracted between the bottom frame and the rotating frame for easy carrying and storage. By setting a torsion spring on the second rotating shaft, when the two rotating frames are not combined, the rotating frame can automatically rotate and combine with the bottom frame under the torsion of the torsion spring, thereby folding and retracting the folding sleeve and protective sleeve. This allows the device to maintain a stable state in the folded state and limits the torsion of the torsion spring, preventing its torsion from affecting the unfolding of the storage device when the rotating frames are combined.

[0019] 3. This concrete storage device, by setting a second rotating shaft between the two bottom frames, allows the bottom frame to be rotated again after the rotating frame and the bottom frame are combined, so that the two bottom frames are combined again, further reducing the space occupied in the retracted state of the storage state, making it convenient for storage and carrying. Limiting the weight of the bottom frame can prevent the bottom frame from tilting up due to the torque of the torsion spring when the rotating frame is combined and fixed. By setting storage grooves on both sides of the bottom frame, the protective film can be pressed and retracted into the storage grooves when the rotating frame and the bottom frame are combined and retracted, thus providing a protective effect for the protective film.

[0022] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0023] like Figures 1 to 6 As shown, a concrete storage device includes two bottom frames 1. A first rotating shaft 2 is rotatably connected to the joint of the bottom frames 1. The bottom frames 1 are rotatably connected through the first rotating shaft 2. Folding sleeves 3 are fixedly connected to the outer sides of the bottom frames 1. A second rotating shaft 4 is rotatably connected to the inner side of the bottom frames 1. A rotating frame 5 is rotatably connected to the bottom frames 1 through the second rotating shaft 4. One end of the folding sleeve 3 is fixedly connected to the side of the rotating frame 5. A protective film 6 is fixedly connected between the two sides of the bottom frames 1 and the rotating frame 5.

[0024] Example 1: The folding sleeve 3 is arc-shaped when extended, and the two folding sleeves 3 are combined to form a semi-cylindrical shape. The folding sleeve 3 is made of polytetrafluoroethylene. By setting the folding sleeve 3 between the bottom frame 1 and the rotating frame 5, when the rotating frame 5 is rotated to a vertical position, the folding sleeve 3 can be unfolded into a semi-cylindrical shape, thereby protecting the concrete stored below from rain and reducing the possibility of damage and deterioration of the concrete during storage. The folding sleeve 3 made of polytetrafluoroethylene has excellent corrosion resistance and high temperature resistance, and can be used stably in hot environments to provide protection.

[0025] Example 2: The rotating frame 5 is made of magnet. The magnetic properties of the mating surfaces of the rotating frame 5 are opposite. By setting the material of the rotating frame 5 to magnet, it can be automatically attracted and fixed under the action of magnetism when mating, thereby keeping the folding sleeve 3 and the protective film 6 in the unfolded state, thus protecting the concrete stored inside. In addition, the device can be folded into a smaller volume when not in use, making it convenient for storage and carrying.

[0026] Example 3: The protective film 6 is fan-shaped and made of transparent polycarbonate film. By setting the protective film 6 on both sides of the folding sleeve 3, the two sides of the storage device are protected and covered, thereby fully covering and protecting the stored concrete. The transparent polycarbonate film has excellent corrosion resistance and is transparent, making it easy to observe the storage condition of the concrete inside. When not in use, it can be folded between the bottom frame 1 and the rotating frame 5 for easy carrying and storage.

[0027] Example 4: A torsion spring 7 is sleeved on the end of the second rotating shaft 4. The torsion of the torsion spring 7 is so that the rotating frame 5 merges with the bottom frame 1. The torsion of the torsion spring 7 is less than the magnetic force between the two rotating frames 5. By setting the torsion spring 7 on the second rotating shaft 4, when the two rotating frames 5 are not merged, the rotating frame 5 can automatically rotate and merge with the bottom frame 1 under the action of the torsion of the torsion spring 7, thereby folding and shrinking the folding sleeve 3 and the protective sleeve 6, so that the device can maintain a stable state in the folded state, limit the torsion of the torsion spring 7, and avoid its torsion affecting the unfolding of the storage device when the rotating frames 5 are merged.

[0028] Example 5: The weight of the bottom frame 1 is greater than the torque of the torsion spring 7. The second rotating shaft 2 is located at the bottom of the connection between the two bottom frames 1. By setting the second rotating shaft 2 between the two bottom frames 1, when the rotating frame 5 and the bottom frame 1 are combined, the bottom frame 1 can be rotated again to make the two bottom frames 1 combine, further reducing the space occupied by the storage state in the retracted state, making it convenient for storage and carrying. Limiting the weight of the bottom frame 1 can prevent the bottom frame 1 from tilting up on both sides when the rotating frame is combined and fixed.

[0029] Example 6: Storage slots 8 are fixedly connected to both sides of the top of the bottom frame 1. The length of the storage slots 8 is adapted to the width of the protective film 6. By setting storage slots 8 on both sides of the bottom frame 1, when the rotating frame 5 and the bottom frame 1 are merged and retracted, the protective film 6 can be pressed and retracted into the storage slots 8, thus providing a protective effect for the protective film 6.

[0030] The working principle of this utility model is as follows: S1. A folding sleeve 3 is set between the bottom frame 1 and the rotating frame 5. When the rotating frame 5 is rotated to a vertical position, the folding sleeve 3 can be unfolded into a semi-cylindrical shape, thereby protecting the concrete stored below from rain and reducing the possibility of damage and deterioration of the concrete during storage. The folding sleeve 3 made of polytetrafluoroethylene has excellent corrosion resistance and high temperature resistance, and can be used stably in hot environments to provide protection. S2. The rotating frame 5 is made of magnet, so that it can be automatically attracted and fixed under the action of magnetism when it is attached, thereby keeping the folding sleeve 3 and the protective film 6 in the unfolded state, thus protecting the concrete stored inside. The device can also be folded into a smaller volume when not in use, making it convenient for storage and carrying.

[0031] Compared with the prior art, the present invention has the following advantages: 1. This concrete storage device, by setting a folding sleeve 3 between the bottom frame 1 and the rotating frame 5, allows the folding sleeve 3 to unfold into a semi-cylindrical shape when the rotating frame 5 is rotated to a vertical position, thereby protecting the concrete stored below from rain and reducing the possibility of damage and deterioration of the concrete during storage. The folding sleeve 3, made of polytetrafluoroethylene, has excellent corrosion resistance and high temperature resistance, and can be used stably in hot environments to provide protection. By setting the rotating frame 5 to a magnet, it can automatically attract and fix itself under magnetic action when it is attached, thereby keeping the folding sleeve 3 and the protective film 6 in the unfolded state, thus protecting the concrete stored inside. In addition, the device can be folded into a smaller volume when not in use, making it convenient for storage and carrying.

[0032] 2. This concrete storage device, by setting protective films 6 on both sides of the folding sleeve 3, provides protective coverage to both sides of the storage device, thereby fully covering and protecting the stored concrete. The transparent polycarbonate film has excellent corrosion resistance and is made of transparent material, making it easy to observe the storage condition of the concrete inside. When not in use, it can be retracted between the bottom frame 1 and the rotating frame 5 for easy carrying and storage. By setting a torsion spring 7 on the second rotating shaft 4, when the two rotating frames 5 are not combined, the rotating frames 5 can automatically rotate and combine with the bottom frame 1 under the torsion of the torsion spring 7, thereby folding and retracting the folding sleeve 3 and the protective sleeve 6, so that the device can maintain a stable state in the folded state, limiting the torsion of the torsion spring 7, and preventing its torsion from affecting the unfolding of the storage device when the rotating frames 5 are combined.

[0033] 3. This concrete storage device, by setting a second rotating shaft 2 between the two bottom frames 1, allows the bottom frames 1 to be rotated again after the rotating frame 5 is merged with the bottom frame 1, so that the two bottom frames 1 are merged, further reducing the space occupied by the storage state in the retracted state, making it convenient for storage and carrying. Limiting the weight of the bottom frame 1 can prevent the bottom frames 1 from tilting up due to the torque of the torsion spring 7 when the rotating frame is merged and fixed. By setting storage grooves 8 on both sides of the bottom frame 1, the protective film 6 can be pressed and retracted in the storage grooves 8 when the rotating frame 5 is merged and retracted with the bottom frame 1, thus providing a protective effect for the protective film 6.
