[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figures 1 to 5 , the present invention provides a technical solution:

[0035] A rock wool color steel plate comprises a color steel plate 1 and a color steel plate 2 of the same size, wherein a connector 1 and a connector 2 are respectively arranged on both sides of the color steel plate 1 and the color steel plate 2, and the connector 1 and the connector 2 are correspondingly distributed on the sides of the adjacent color steel plate 1 and the color steel plate 2, and the connector 1 and the connector 2 are fixedly engaged with each other, and a locking component 5 is inserted inside the two.

[0036] The connecting piece 1 3 , the connecting piece 2 4 and the clamping assembly 5 together constitute a fixed connection mechanism of the color steel plate, thereby achieving the connection and fixation of the color steel plate.

[0037] By adopting the above technical scheme, by designing a fixed connection mechanism for color steel plates in the present invention, the connection and fixation of color steel plate 1 and color steel plate 2 are realized through the mechanism. Compared with the traditional bolt fixing method, it is not easy to be corroded and damaged, and the occurrence of water leakage is reduced. The installation method of the structure is simple and convenient, which improves the assembly efficiency of workers. The locking component 5 in the fixed connection mechanism can not only further increase the stability of the connection structure, but also act as the skeleton of the house when the house is built, increase the strength of the plate body, and reduce the influence of the external environment.

[0038] As an embodiment of the present invention, Figures 1 to 4As shown, the connecting member 3 includes a splint 32, a connecting member 33, and a limiting member 34; two groups of arc-shaped structure splints 32 are symmetrically arranged on the right side of the color steel plate 2, and one end of the splint 32 is fixed to the color steel plate 1, and the other end is a free end for engagement, the longitudinal cross-section of the two splints 32 is designed as a circular structure and matches the connecting member 24, the length of the splint 32 is the same as the length of the color steel plate 1, and the two are designed in parallel, the inner side surfaces of the two splints 32 are vertically fixedly connected with the connecting member 33 near the free end, and the end of the connecting member 33 away from the splint 32 is fixedly connected with the limiting member 34, the connecting member 33 is designed as a cone-like shape, the length of the connecting member 33 and the limiting member 34 is shorter than the splint 32, the outer surfaces of the two groups of splints 32 are provided with arc-shaped elastic members 31 near the color steel plate 2, and the two ends of the elastic member 31 are respectively connected and fixed to the splint 32 and the color steel plate 2, the splint 32 and the elastic member 31 are both made of elastic stainless steel metal. A connector 35 is arranged between the two splints 32, and one end of the connector 35 is vertically fixedly connected to the middle position of the right side of the color steel plate. The connector 35 has the same structure as the connecting member 33, and a limiting member 34 is also arranged at the other end. The two connecting members 33 and the connector 35 are designed in a triangular orientation. The connecting member 4 includes a connecting hole 41, a connecting tube 42, and a rubber member 43. The connecting tube 42 is designed in a cylindrical hollow structure and is fixedly connected to the middle part of the left side of the color steel plate 2, and the outer diameter of the connecting tube 42 is equal to the inner diameter between the two groups of splints 32. The outer surface of the connecting tube 42 is provided with a connecting hole 41 at the corresponding position of the two connecting members 33 and the connector 35, and the connecting hole 41 matches with each other. One end of the connecting hole 41 passes through the connecting tube 42, and the outer opening end is designed in an arc-shaped structure.

[0039] By adopting the above technical solution, when in use, the color steel plate 1 and the color steel plate 2 are placed in parallel, the connecting piece 1 3 corresponds to the connecting piece 2 4, and then the color steel plate 1 is pushed. At this time, the connecting tube 42 contacts the free end openings of the two clamping plates 32 and squeezes them. At this time, the clamping plates 32 made of elastic stainless steel metal expand relatively, and the elastic member 31 also bends and accumulates momentum until the connecting tube 42 is completely inserted between the two clamping plates 32. The design of the elastic member 31 increases the elastic deformation capacity of the clamping plates 32 on the one hand, and increases the service life. On the other hand, it increases the clamping force of the clamping plates 32 to clamp the connecting tube 42, making the connection more firm. For fastening, when the connecting tube 42 completely enters the interior of the splint 32, the connecting piece 33 and the limiting piece 34 at the freely movable end of the splint 32 are inserted into the interior of the connecting tube 42 through the connecting hole groove 41 opened on the outer surface of the connecting tube 42 to be clamped and fixed, and the plug-in piece 35 on the left side of the color steel plate 2 is inserted into the interior of the connecting tube 42 through the connecting hole groove 41 to complete the clamping connection and fixation. This method is not only simpler and more convenient to operate than the traditional bolt fixing method, but also can reduce the risk of exposed bolts being eroded by external rainwater and rusting, causing damage to the connection and the possibility of water leakage.

[0040] As an embodiment of the present invention, Figure 4 As shown, a rubber member 43 is glued and fixed at a position corresponding to the free end of the clamping plate 32 on the outer surface of the connecting tube 42 , and a plug-in notch is provided at a position corresponding to the free end of the clamping plate 32 .

[0041] By adopting the above technical solution, the design purpose of the rubber part 43 is that when the connecting tube 42 is fully engaged and inserted into the inside of the clamp 32, the clamp 32 clamps and fixes the connecting tube 42. At this time, the free movable end of the clamp 32 is inserted into the notch of the rubber part 43, and the gap between the sealing clamp 32 and the connecting tube 42 is wrapped by the elastic deformation of the rubber part 43, thereby further reducing the probability of rainwater penetration during subsequent use and increasing the use effect of the device.

[0042] As an embodiment of the present invention, Figure 4 and Figure 5 As shown, the locking assembly 5 includes a transverse groove 51, an ear plate 52, a plug hole 53, a threaded hole 54, and a transverse rod 55; the transverse rod 55 is designed by a cylindrical hollow structure, and it matches the inner diameter of the connecting piece, and the two ends of the transverse rod 55 are integrally connected with and fixed with the ear plate 52, and the middle part of the outer surface of the ear plate 52 is provided with a threaded hole 54, and the outer surface of the transverse rod 55 is provided with a transverse groove 51 at a position corresponding to the connecting piece 33 and the plug-in piece 35, and the two ends of the transverse groove 51 are provided with plug-in holes 53 connected thereto, and the plug-in hole 53 is inclined and has a diameter larger than the diameter of the limit piece 34, and the opening width of the transverse groove 51 is smaller than the diameter of the limit piece 34.

[0043] By adopting the above technical scheme and based on the above embodiments, after the connector 1 3 is engaged and fixed with the connector 2 4 to complete the preliminary connection and fixation of the color steel plate 1 and the color steel plate 2 2, the user inserts the cross bar 55 through the openings at the front and rear ends of the front and rear connectors 1 3 and the connector 2 4, and makes the insertion hole 53 on the outer surface of the cross bar 55 correspond to the limiter 34 located inside the connecting tube 42, and then slowly pushes the cross bar 55 into the interior of the connecting tube 42, so that the limiter 34 passes through and enters the interior of the transverse groove 51 for engagement and fixation, thereby achieving engagement of the limiter 34 inside the connecting tube 42, further limiting and fixing the plug-in component 35 and the connector 33, and the insertion of the cross bar 55 can not only further achieve the stability of the connection state of the connector 1 3 and the connector 2 4, but also increase the strength of the connection between the color steel plate 1 and the color steel plate 2 2, and in the subsequent use process, the cross bar 55 is connected and fixed to other frames of the house through the ear plate 52, and can also replace the roof frame, reduce the construction steps, and improve the use efficiency of the device.

[0044] As an embodiment of the present invention, Figure 5 As shown, the length of the cross bar 55 is the same as that of the clamping plate 32 and the connecting tube 42 , the assembled ear plate 52 is exposed outside the clamping plate 32 and the connecting piece, and a sealing gasket is glued inside the plug hole 53 .

[0045] It is worth noting that although the cross bar 55 matches the inner diameter of the connecting tube 42 and is designed to fit tightly, in order to further prevent the colored steel plate of the cross bar 55 from sliding off, when installing the threaded holes 54 in the ear plates 52 at both ends of the cross bar 55, during the installation of the nuts, the nuts should be sleeved with gaskets, and the gasket diameter should cover the plug-in hole 53 and rest against the edge of the cross groove 51 to prevent detachment, and the rubber pad glued inside the plug-in hole 53 further reduces the chance of subsequent rainwater entering.

[0046] As an embodiment of the present invention, Figure 4 As shown, the electric heating wire 56 is fixed to the internal spiral distribution of the cross bar 55, the internal plug-in of the color steel plate 1 is fixed with a heat conductive sheet 11, the internal plug-in of the color steel plate 2 is fixed with a heat conductive sheet 21, the heat conductive sheet 11 is connected and fixed to the clamping plate 32, the heat conductive sheet 21 is connected and fixed to the connecting tube 42, and the heat conductive sheet 11, the heat conductive sheet 21, the electric heating wire 56 and the clamping assembly 5 together constitute a heating and heat preservation mechanism.

[0047] By adopting the above technical scheme, in rainy and snowy weather, especially when the temperature is low, the electric heating wire 56 conducts electricity to heat the inside of the cross bar 55, and then conducts heat to the inside of the color steel plate 1 and the color steel plate 2 through the connecting tube 42 and the clamping plate 32, the heat conducting plate 11 and the heat conducting plate 21, so that the color steel plate is heated as a whole, and the snow covering the surface is melted, reducing the gravity pressure on the color steel plate, and also preventing the color steel plate from being squeezed and damaged by ice. At the same time, long-term opening can also keep the room warm and improve comfort.

[0048] Working principle: When in use, the color steel plate 1 and the color steel plate 2 are placed in parallel, the connecting piece 1 3 corresponds to the connecting piece 2 4, and then the color steel plate 1 is pushed. At this time, the connecting tube 42 contacts the free end openings of the two clamping plates 32 and squeezes them. At this time, the clamping plates 32 made of elastic stainless steel metal expand relatively, and the elastic piece 31 also bends and accumulates momentum until the connecting tube 42 is completely inserted between the two clamping plates 32. The design of the elastic piece 31 increases the elastic deformation capacity of the clamping plates 32 on the one hand, and increases the service life. On the other hand, it increases the clamping force of the clamping plates 32 to clamp the connecting tube 42, making the connection more secure. When the connecting tube 42 is completely inserted into the interior of the clamping plate 32, the connecting piece 33 and the limiting piece 34 at the free end of the clamping plate 32 are inserted into the interior of the connecting tube 42 through the connecting hole groove 41 provided on the outer surface of the connecting tube 42 to be fixed and limited, and the plug-in piece 35 on the left side of the color steel plate 2 is inserted into the interior of the connecting tube 42 through the connecting hole groove 41 to complete the clamping connection and fixing. This method is not only simpler and more convenient to operate than the traditional bolt fixing method, but also can reduce the probability of damage to the connection and water leakage caused by the exposed bolts being eroded by rainwater and rusting;

[0049] The rubber member 43 is designed so that when the connecting tube 42 is fully engaged and inserted into the clamping plate 32, the clamping plate 32 clamps and fixes the connecting tube 42. At this time, the free end of the clamping plate 32 is inserted into the notch of the rubber member 43. The rubber member 43 elastically deforms to wrap and seal the gap between the clamping plate 32 and the connecting tube 42, thereby further reducing the probability of rainwater penetration during subsequent use and increasing the use effect of the device.

[0050] After the connector 1 3 and the connector 2 4 are engaged and fixed, and the preliminary connection and fixation of the color steel plate 1 and the color steel plate 2 2 are completed, the user inserts the cross bar 55 through the openings at the front and rear ends of the front and rear connectors 1 3 and the connector 2 4, and makes the insertion hole 53 on the outer surface of the cross bar 55 correspond to the limiter 34 located inside the connecting tube 42, and then slowly pushes the cross bar 55 into the interior of the connecting tube 42, so that the limiter 34 passes through and enters the interior of the transverse groove 51 for engagement and fixation, so as to achieve engagement with the limiter 34 inside the connecting tube 42, further limit and fix the plug-in member 35 and the connector 33, and the insertion of the cross bar 55 can not only further achieve the stability of the connection state of the connector 1 3 and the connector 2 4, but also increase the strength of the connection between the color steel plate 1 and the color steel plate 2 2, and in the subsequent use process, the ear plate 52 is connected and fixed to other frames of the house, and the cross bar 55 can also replace the roof frame, reduce the construction steps, and improve the use efficiency of the device;

[0051] In rainy and snowy weather, especially when the temperature is low, the electric heating wire 56 conducts electricity to heat the inside of the crossbar 55, and then conducts heat to the inside of the color steel plate 1 and the color steel plate 2 through the connecting tube 42 and the clamping plate 32, the heat conductive sheet 11 and the heat conductive sheet 21, so that the color steel plate is heated as a whole, and the snow covering the surface is melted to reduce the gravity pressure on the color steel plate, and at the same time, it is also to avoid ice from squeezing and damaging the color steel plate. At the same time, long-term opening can also keep the room warm and improve comfort.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
