The device can also be positioned in other different ways, and corresponding explanations are made for the spatial relative descriptions used here.

[0026] Now, a prefabricated lightweight composite insulation board and its installation process provided by the present invention will be described.

[0027] Such as Figure 1 And Figure 2As shown in the figure, the first embodiment of the present invention provides a prefabricated lightweight composite insulation board, which includes a composite board body 1 and a connection frame 2 fixedly surrounded around the periphery of the composite board body 1; connection grooves 21 are formed on the left and right sides of the connection frame 2 in an interlaced manner, and adjacent connection frames 2 are inserted into each other through the connection grooves 21.

[0028] As Figure 3 and Figure 4 shown in the figure, a plurality of L-shaped clamping blocks 22 are fixed in the connection grooves 21 on one side of the connection frame 2, and a plurality of clamping grooves 23 are formed in the connection grooves 21 on the other side of the connection frame 2. The clamping blocks 22 on the adjacent connection frames 2 are inserted into the clamping grooves 23, and a limiting groove 24 for inserting the end portions of the clamping blocks 22 is formed at the top inside the clamping grooves 23; a fixing mechanism 5 for fixing a row of clamping blocks 22 after they are inserted into the limiting groove 24 is arranged inside the connection frame 2; a plug board 3 is arranged at the bottom of the connection frame 2, and a slot 4 for inserting the upper plug board 3 is formed at the top of the connection frame 2; after the plug board 3 is inserted into the slot 4, the end portions of the clamping blocks 22 are inserted into the limiting groove 24, and the fixing mechanism 5 fixes a row of clamping blocks 22.

[0029] Compared with the prior art, the prefabricated lightweight composite insulation board provided in this embodiment realizes the insertion fit of the clamping blocks 22 and the clamping grooves 23 through the mutual insertion of the adjacent connection frames 2. Then, sliding the connection frame 2 downward can make the clamping blocks 22 inserted into the limiting groove 24, and at the same time, the plug board 3 is inserted into the slot 4, which not only realizes the connection and limitation of the left and right two insulation boards in the horizontal direction, but also can realize the connection and limitation of the upper and lower two insulation boards in the horizontal direction. Then, by fixing the positions of the clamping blocks 22 through the fixing mechanism 5, the overall fixation of the adjacent insulation boards in the up, down, left, and right directions can be realized, and the connection strength between the adjacent insulation boards is improved.

[0030] As Figure 4 and Figure 5 shown in the figure, a specific embodiment provided by the present invention on the basis of the first embodiment is as follows: The fixing mechanism 5 includes a moving plate 51, a fixing spring 52 and a filling block 53. A moving groove 25 communicating with the side of a row of clamping grooves 23 is formed inside the connection frame 2, and the moving plate 51 is slidably arranged in the moving groove 25; a receiving groove 511 is formed on the side of the moving plate 51 facing the clamping groove 23, the fixing spring 52 is arranged in the receiving groove 511, the filling block 53 is slidably arranged at the opening of the receiving groove 511 and is connected to the fixing spring 52, and the fixing spring 52 is always in a compressed state; a linkage mechanism 6 is arranged inside the plug board 3, and the linkage mechanism 6 is used to drive the moving plate 51 downward when the plug board 3 is inserted into the slot 4 until the filling block 53 is inserted into the clamping groove 23 below the clamping block 22. At this time, the top surface of the filling block 53 is in contact with the bottom surface of the clamping block 22, and the bottom end of the moving plate 51 is in contact with the bottom wall of the moving groove 25.

[0031] After the connecting frames 2 on the left and right sides are inserted into each other, slide the connecting frame 2 downward so that the insertion plate 3 is inserted into the slot 4. At this time, the clamping block 22 is inserted into the limiting slot 24. At the same time, the linkage mechanism 6 drives the moving plate 51 to slide downward. When the filling block 53 moves below the clamping block 22, it is inserted into the clamping slot 23, fixing the position between the clamping block 22 and the clamping slot 23, thereby realizing the fixation between the adjacent connecting frames 2 on the left and right.

[0032] As Figure 4 and Figure 5 shown, a specific implementation manner provided by the present invention on the basis of the first implementation manner is as follows: When the filling block 53 is in the initial state, it is located in both the receiving groove 511 and the limiting groove 24 at the same time. The bottom surface of the filling block 53 located in the limiting groove 24 is inclined.

[0033] Since the fixing spring 52 is always in a compressed state, when the thermal insulation board is not installed, the filling block 53 being located in both the receiving groove 511 and the limiting groove 24 at the same time can reduce the compression degree of the fixing spring 52, making it more stable during subsequent expansion and contraction; and when the clamping block 22 moves towards the limiting groove 24 in the clamping slot 23, it can squeeze the inclined surface of the filling block 53 to make it completely enter the receiving groove 511, without affecting the insertion of the clamping block 22 into the limiting groove 24, thereby ensuring the convenience of the installation operation.

[0034] As Figure 6 and Figure 7 shown, a specific implementation manner provided by the present invention on the basis of the first implementation manner is as follows: The linkage mechanism 6 includes a rotating shaft 61, a gear 62, a rack 63 and a self-driving component 64; the rotating shaft 61 is vertically rotatably arranged at the bottom of the insertion plate 3, the gear 62 is located inside the insertion plate 3 and is coaxially fixed with the rotating shaft 61, the rack 63 is horizontally slidably arranged inside the insertion plate 3 and is always meshed with the gear 62; an extrusion groove 26 for the rack 63 to insert is opened at the top of the moving groove 25, the end surface of the rack 63 facing the moving plate 51 is inclined and is used for squeezing the moving plate 51 downward; the self-driving component 64 is used to drive the rotating shaft 61 to rotate when the insertion plate 3 is inserted into the slot 4, so that the rack 63 squeezes the moving plate 51 downward.

[0035] When pushing the connecting frame 2 downward to insert the insertion plate 3 into the slot 4, the self-driving component 64 drives the rotating shaft 61 to rotate, the rotating shaft 61 drives the gear 62 to rotate, the gear 62 drives the rack 63 to move into the extrusion groove 26, and the inclined surface at the end of the gear 62 squeezes the top of the moving plate 51 to slide downward until the filling block 53 moves below the corresponding clamping block 22, improving the operation convenience and installation efficiency.

[0036] As Figure 8As shown in the figure, a specific implementation provided by the present invention on the basis of the first embodiment is as follows: One side of the top of the moving plate 51 is inclined towards the slot 4, and the inclined surface of the moving plate 51 is adapted to the inclined surface of the rack 63.

[0037] The inclined surface at the top of the moving plate 51 can cooperate with the inclined surface of the rack 63, enabling the rack 63 to more easily press the moving plate 51 downward, reducing the working burden of the self-driving component 64.

[0038] As Figures 7 to 9 As shown in the figure, a specific implementation provided by the present invention on the basis of the first embodiment is as follows: The plug board 3 includes a fixed shell 31 and a sliding plate 32. The top of the fixed shell 31 is fixed to the bottom of the connection frame 2. The sliding plate 32 is slidably arranged at the bottom of the fixed shell 31. The rotating shaft 61 is rotatably connected to the fixed shell 31 and penetrates through the sliding plate 32. The gear 62 is located inside the fixed shell 31; the rack 63 is simultaneously slidably connected in the fixed shell 31 and the sliding plate 32, and the top of the extrusion groove 26 is in a closed state; a relief groove 27 for the rack 63 to insert is opened at the bottom of the connection frame 2; a relief opening 311 for accommodating the rack 63 is opened at the side of the fixed shell 31; when the sliding plate 32 slides towards the inside of the fixed shell 31, the self-driving component 64 drives the rotating shaft 61 to rotate.

[0039] When pushing the connection frame 2 downward to insert the plug board 3 into the slot 4, the bottom end of the sliding plate 32 first fits with the inner bottom wall of the slot 4. At this time, the height of the rack 63 no longer changes. Continuing to slide the connection frame 2 downward to insert the fixed shell 31 into the slot 4. At this time, the sliding plate 32 is inserted into the inside of the fixed shell 31, and the self-driving component 64 drives the rotating shaft 61 to rotate, causing the rack 63 to move towards the extrusion groove 26. At this time, the movement trajectory of the rack 63 is a straight line, improving the accuracy and sliding stability when it is inserted into the extrusion groove 26, and ensuring the convenience of the installation operation; and the top of the extrusion groove 26 is in a closed state, that is, by the rack 63 being simultaneously located in the sliding plate 32 and the extrusion groove 26, the limiting effect between the upper and lower adjacent connection frames 2 is further strengthened. As Figure 6 As shown in the figure, a specific implementation provided by the present invention on the basis of the first embodiment is as follows: The self-driving component 64 includes a screw rod 641 and a screw tube 642. The screw rod 641 is coaxially fixed to the bottom of the rotating shaft 61 and is integrally formed with it. The screw rod 641 is fixedly embedded in the inner bottom wall of the slot 4 and the screw tube 642 is screwed into it; the bottom of the screw rod 641 does not protrude from the bottom surface of the sliding plate 32 when in the initial state.

[0040] After the sliding plate 32 is inserted into the slot 4 and fits against its bottom wall, the screw 641 has not yet been threadedly engaged with the screw tube 642, ensuring the linear accuracy of the rack 63 during movement; when the connecting frame 2 continues to drive the fixed housing 31 into the slot 4, the fixed housing 31 drives the screw 641 to be inserted into the screw tube 642 through the rotating shaft 61, so as to realize the automatic rotation of the screw 641 and the rotating shaft 61, thereby improving the operational convenience during installation.

[0041] As Figure 1 shown, based on the same inventive concept, the second embodiment of the present invention provides an installation process for a prefabricated lightweight composite insulation board. Using the prefabricated lightweight composite insulation board of the first embodiment, it includes the following steps: S1. First, clean the wall surface and apply an interface agent, and apply an adhesive on the back of the board body; S2. Install each row of insulation boards from bottom to top. Snap the insulation boards onto the wall surface so that the adjacent connecting frames 2 are initially plugged together through the connecting grooves 21. At this time, the locking blocks 22 are inserted into the corresponding card slots 23, and then slide this insulation board downward so that the end of the locking block 22 is inserted into the limiting groove 24. At the same time, the insertion plate 3 is inserted into the slot 4 of the lower connecting frame 2, and the fixing mechanism 5 fixes the entire row of locking blocks 22. Repeat the above steps for the installation of subsequent insulation boards.

[0042] For the installation process of the prefabricated lightweight composite insulation board provided in this embodiment, compared with the prior art, the installation of the insulation board is a row-by-row installation method from bottom to top, improving the safety and stability of the entire installation process, and the installation operation of the insulation board is convenient, which helps to improve the overall installation efficiency.

[0043] A specific implementation manner provided by the present invention based on the second embodiment is as follows: Before installing the insulation board, first install a bottom plate at the bottom of the wall, and pre-open a slot 4 on the bottom plate for the insertion plate 3 to insert; when prefabricating the insulation boards at both ends of the wall, cancel the cutting of one side of the connecting groove 21.

[0044] The structure and installation process of the connecting frame 2 at the end of the wall are optimized, making the installation of the insulation board more convenient and efficient, while ensuring the quality and stability of the installation.
