Description

Technical Field

[0001] The invention relates to the technical field of cold storage decorative panels, and in particular to a cold storage decorative panel with heat-insulating and fire-proof properties. Background Art

[0002] Cold storage panels generally refer to building materials used to construct cold storage or freezer storage. They are a special type of sandwich panels that have the characteristics of heat preservation, heat insulation and moisture resistance, and can effectively maintain the temperature and humidity inside the cold storage.

[0003] A Chinese patent (CN106827721A) discloses a cold storage panel assembly. The patent arranges the first connecting member and the second connecting member in an alternating manner, so that the connection between the cold storage panels is more closed, has good thermal insulation and is easy to install; the third connecting member is connected and fixed to the upper aluminum plate, and when the two connected cold storage panels are disassembled, they can still be reused, which is energy-saving and environmentally friendly; the first connecting member and the second connecting member are respectively composed of a first aluminum plate and a second aluminum plate and a polyurethane interlayer sandwiched between the first aluminum plate and the second aluminum plate, which has good thermal insulation.

[0004] In the prior art, a hexagonal wrench is required to rotate the eccentric shaft when installing and connecting the cold storage panels. When a large number of cold storage panels are connected, they need to be connected one by one with a hexagonal wrench. The manual connection method is inefficient, especially in large cold storages or when frequent assembly and disassembly are required. In addition, manual connection may make it difficult to ensure that each connection has the same strength and precision, and it will also consume a lot of time and human resources. Summary of the invention

[0005] In order to solve the technical problems raised in the above-mentioned background technology, the present invention provides a cold storage decorative plate with heat preservation and fire prevention, which has the advantages that: through the setting of the connecting component, the two plate bodies can be quickly connected. Specifically, when the two plate bodies are connected, the plug rod is first inserted into the slide groove of the connecting cavity, and the clamping rod is clamped into the fixed groove inside the plug rod. At this time, the clamping block and the clamping groove are clamped to achieve docking of the two plate bodies. When disassembling, it is only necessary to rotate the handle to drive the slider to slide in the slide groove, squeeze the pressure rod, and then drive the clamping rod to disengage from the plug rod to achieve the separation of the two plate bodies. Compared with the prior art, through this connection method, the connection of the two plate bodies can be completed in a short time, which improves the construction efficiency, and the combination of the clamping block and the clamping groove can provide a strong connecting force to ensure the firmness and stability of the connection, and also make it more convenient to maintain, replace or move the plate body.

[0006] In order to achieve the above object, the present invention specifically adopts the following technical solutions:

[0007] A cold storage decorative plate with heat preservation and fire prevention, comprising a plate body, a connecting cavity is opened on one side of the plate body, and a connecting component is arranged inside the connecting cavity;

[0008] The connecting assembly includes a connecting block, which is slidably connected to the connecting cavity. One end of the connecting block is fixedly connected to a first spring. A clamping rod is rotatably connected inside the connecting cavity. An insertion rod is fixedly connected to the other side of the plate body. A sliding groove is provided inside the connecting cavity. The insertion rod is slidably connected to the sliding groove. A fixed groove is provided inside the insertion rod, and the fixed groove matches one end of the clamping rod.

[0009] Through the above technical solution: the connecting component can realize the quick connection of the two plate bodies. Specifically, when the two plate bodies are connected, the plug rod is first inserted into the slide groove of the connecting cavity, and the card rod is inserted into the fixed groove inside the plug rod. At this time, the card block and the card groove are carded to realize the docking of the two plate bodies. Through this connection method, the connection of the two plate bodies can be completed in a short time, which improves the construction efficiency. In addition, the combination of the card block and the card groove can provide a strong connecting force, ensure the firmness and stability of the connection, and make it more convenient to maintain, replace or move the plate body.

[0010] The present invention is further configured such that a second spring is fixedly connected to one end of the clamping rod away from the connecting block, a limiting groove is provided inside the connecting cavity, a pressure rod is slidably connected inside the limiting groove, and the pressure rod is fixedly connected to one end of the clamping rod.

[0011] Through the above technical solution: when the slider slides, it squeezes the pressure rod, and when the pressure rod moves downward, it drives the clamping rod to rotate a specific angle. At this time, the second spring contracts, and the clamping rod withdraws from the inside of the insertion rod when it rotates, thereby realizing the separation of two adjacent plates.

[0012] The present invention is further configured such that a worm is rotatably connected inside the connecting cavity, a worm wheel is provided on one side of the worm, a threaded rod is fixedly connected inside the worm wheel, and the threaded rod is rotatably connected to the inner wall of the connecting cavity.

[0015] Through the above technical solution: when the engagement is completed and needs to be removed, the worm gear is driven to rotate by the worm, and the rotation of the worm gear drives the threaded rod to rotate, and the rotation of the threaded rod drives the slider to slide inside the slide groove.

[0016] The present invention is further configured such that metal outer plates are provided on both sides of the plate body, one end of the worm extends through the plate body and is fixedly connected to a turning handle, and the turning handle and an outer wall of one of the metal outer plates are both marked.

[0017] Through the above technical solution: the mark is composed of a circle and a triangle. When the insertion rod is inserted into the fixed groove inside the clamp rod, the circular mark on the handle is aligned with the circle, and the triangular mark is aligned with the triangle. When the two plates need to be separated, the side with the circular mark needs to be rotated to the triangular mark. At this time, the two plates can be separated. The mark ensures the accurate rotation angle of the plate during the connection process.

[0018] The metal outer plate increases the overall structural strength of the plate body and can also prevent moisture from penetrating into the interior of the cold storage plate, maintaining a relatively low humidity level inside the cold storage to prevent the goods in the cold storage from rotting or mildewing. At the same time, the metal outer plate is usually easier to clean than other materials, which helps maintain the hygiene standards of the cold storage.

[0019] The present invention is further configured such that a clamping block is fixedly connected to one end of the plate body, and a clamping slot is provided at the other end of the plate body, and the clamping block is clamped with the clamping slot.

[0023] The present invention is further configured such that the plate body is bonded to the flame retardant layer and the reinforcement layer by mortar, and the two metal outer plates are made of stainless steel.

[0024] Through the above technical solution: stainless steel has excellent corrosion resistance, can resist the erosion of humidity, chemicals and some corrosive media, can keep the surface of the plate smooth and not easy to rust for a long time, stainless steel also has a smooth, stainless, easy to clean surface characteristics, not easy to accumulate dirt or bacteria, which is conducive to maintaining the hygiene of the storage environment.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0041] Reference Figure 1-Figure 9 A cold storage decorative plate with heat preservation and fire prevention, comprising a plate body 1, a connecting cavity 4 is opened on one side of the plate body 1, and a connecting component is arranged inside the connecting cavity 4;

[0042] The connecting assembly includes a connecting block 6, which is slidably connected to the connecting cavity 4. One end of the connecting block 6 is fixedly connected to a first spring 7. The interior of the connecting cavity 4 is rotatably connected to a clamping rod 8. The other side of the plate body 1 is fixedly connected to an insertion rod 5. A sliding groove is provided inside the connecting cavity 4. The insertion rod 5 is slidably connected to the sliding groove. A fixed groove is provided inside the insertion rod 5, and the fixed groove matches one end of the clamping rod 8.

[0043] By setting the connecting component, the two plate bodies 1 can be quickly connected. Specifically, when the two plate bodies 1 are connected, first insert the insertion rod 5 into the slide groove of the connecting cavity 4, and then insert the clamping rod 8 into the fixed groove inside the insertion rod 5. At this time, the clamping block 16 and the clamping groove 17 are clamped to achieve the docking of the two plate bodies 1. When disassembling, it is only necessary to rotate the handle 11 to drive the slider 13 to slide in the slide groove, squeeze the pressure rod 14, and then drive the clamping rod 8 to disengage from the insertion rod 5 to achieve the separation of the two plate bodies 1. Compared with the prior art, through this connection method, the connection of the two plate bodies 1 can be completed in a short time, which improves the construction efficiency. In addition, the combination of the clamping block 16 and the clamping groove 17 can provide a strong connecting force, ensure the firmness and stability of the connection, and make it more convenient to maintain, replace or move the plate body 1.

[0044] Reference Figure 3-Figure 8 The end of the clamping rod 8 away from the connecting block 6 is fixedly connected to the second spring 9, a limiting groove is provided inside the connecting chamber 4, and a pressure rod 14 is slidably connected inside the limiting groove. The pressure rod 14 is fixedly connected to one end of the clamping rod 8, and a worm 10 is rotatably connected inside the connecting chamber 4. A worm wheel 12 is provided on one side of the worm 10. A threaded rod 15 is fixedly connected inside the worm wheel 12. The threaded rod 15 is rotatably connected to the inner wall of the connecting chamber 4, the worm 10 is meshed with the worm wheel 12, and a slider 13 is threadedly connected to the outer wall of the threaded rod 15. A sliding groove is provided inside the connecting chamber 4, and the slider 13 is slidably connected to the sliding groove. The slider 13 is located on one side of the pressure rod 14.

[0045] When the engagement is completed and needs to be removed, the worm gear 12 is driven to rotate by the worm screw 10. When the worm gear 12 rotates, it drives the threaded rod 15 to rotate. When the threaded rod 15 rotates, it drives the slider 13 to slide inside the slide groove, squeezing the pressure rod 14. When the pressure rod 14 moves downward, it drives the clamping rod 8 to rotate a specific angle. At this time, the second spring 9 contracts, and the clamping rod 8 withdraws from the inside of the insertion rod 5 when it rotates, thereby realizing the separation of two adjacent plate bodies 1.

[0046] Reference Figure 1-Figure 2 Metal outer plates 2 are provided on both sides of the plate body 1. One end of the worm 10 extends through the outside of the plate body 1 and is fixedly connected to a handle 11. The handle 11 and the outer wall of one of the metal outer plates 2 are both marked.

[0047] Through the setting of the metal outer plate 2, the metal outer plate 2 can effectively isolate the temperature inside and outside the cold storage, maintain the stability of the temperature inside the cold storage and prevent heat penetration. At the same time, the metal outer plate 2 has high corrosion resistance, which helps to extend the service life of the cold storage plate;

[0048] The mark is composed of a circle and a triangle. When the insertion rod 5 is inserted into the fixed groove inside the clamp rod 8, the circular mark on the handle 11 is aligned with the circle, and the triangular mark is aligned with the triangle. When the two plates 1 need to be separated, the side with the circular mark needs to be rotated to the triangular mark. At this time, the two plates 1 can be separated. After separation, the handle 11 is rotated in the opposite direction to return the circular mark to the initial position again, ensuring the accurate rotation angle of the plates during the connection process, waiting for the next separation.

[0049] Reference Figure 7 A clamping block 16 is fixedly connected to one end of the plate body 1 , and a clamping slot 17 is provided at the other end of the plate body 1 , and the clamping block 16 is clamped with the clamping slot 17 .

[0050] By setting the block 16 and the slot 17, the connection between the two plates 1 can be made more stable. Specifically, when the insertion rod 5 is inserted into the clamp rod 8, the block 16 will also be inserted into the slot 17, reducing the shaking or looseness that may occur after the connection.

[0051] Reference Fig. 9 A flame retardant layer 18 is provided between the plate body 1 and one of the metal outer plates 2, a reinforcing layer 19 is provided between the plate body 1 and the other metal outer plate 2, a reinforcing member 3 is provided inside the plate body 1, the plate body 1 and the flame retardant layer 18 and the reinforcing layer 19 are bonded by mortar, and the two metal outer plates 2 are made of stainless steel.

[0052] The flame retardant layer 18 is cement mortar with flame retardant polyester fiber as a carrier. If a fire occurs, it will slow down the spread of flames and reduce the combustion temperature, thereby increasing the safety of the cold storage;

[0053] The reinforcement layer 19 is corrugated galvanized steel, which increases the bending rigidity of the steel, making it more resistant to external pressure and load, thereby enhancing the overall structural strength of the cold storage panel;

[0054] The reinforcement 3 can improve the strength of the cold storage panel;

[0055] The metal outer plate 2 is made of stainless steel and has excellent corrosion resistance. It can resist the erosion of humidity, chemicals and some corrosive media. It is particularly important for structures in humid environments such as cold storage, because stainless steel can maintain a smooth surface and is not easy to rust for a long time.

[0056] Working principle: When in use, firstly, multiple plates 1 are spliced ​​together, and the plug rod 5 is inserted into the slide groove of the connecting cavity 4. When it is inserted, the plug rod 5 pushes the connecting block 6 to slide and drives the first spring 7 on one side to contract. When the fixing groove of the plug rod 5 does not contact the card rod 8, because one side of the card rod 8 is in an arc shape, the card rod 8 will rotate, driving the second spring 9 on the other side to contract. When the fixed groove contacts the card rod 8, the card rod 8 will be stuck into the inside of the plug rod 5. At this time, the second spring 9 on the other side rebounds. When the rod 5 is inserted into the inside of the clamping rod 8, the clamping block 16 will also be clamped with the clamping groove 17, further strengthening the stability of the connection and realizing the docking of the two plate bodies 1. When the two plate bodies 1 need to be separated, the handle 11 needs to be rotated. Before rotating the handle 11, the circular mark on the handle 11 is aligned with the circle, and the triangular mark is aligned with the triangle. When rotating, the handle 11 drives the worm 10 to rotate, and then drives the worm wheel 12 to rotate. When the worm wheel 12 rotates, it drives the threaded rod 15 to rotate. When the threaded rod 15 rotates, it drives the slider 13 to slide inside the slide groove. , squeeze the pressure rod 14, and when the pressure rod 14 moves downward, it drives the clamping rod 8 to rotate a specific angle. At this time, the second spring 9 contracts, and the clamping rod 8 withdraws from the inside of the plug rod 5 when it rotates. At this time, the circular mark rotates to the triangular mark to separate the two adjacent plate bodies 1. After the separation is completed, the handle 11 is rotated in the opposite direction to make the circular mark return to the initial position again, waiting for the next installation and separation; the flame retardant layer 18 between the plate body 1 and the metal outer plate 2 is a cement mortar with flame retardant polyester fiber as a carrier. If a fire occurs, it will slow down the spread of flames and reduce the combustion temperature, thereby increasing the safety of the cold storage. The reinforcement layer 19 and the reinforcement 3 are wavy galvanized steel, which increases the bending stiffness of the steel, making it more resistant to external pressure and load, thereby enhancing the overall structural strength of the cold storage board. The metal outer plate 2 is made of stainless steel with excellent corrosion resistance, and can resist the erosion of humidity, chemicals and some corrosive media. It is particularly important for structures in humid environments such as cold storage, because stainless steel can maintain a smooth surface for a long time and is not easy to rust.
