The movable plate 44 is disposed between the mounting plate 7 and the multiple connecting frame assemblies 2. A first lead screw 41 is mounted on one side of the mounting plate 7 and on the bottom inner side of the movable plate 44 via a bearing.

[0018] Specifically, a guide rod 43 is fixedly installed on one side of the mounting plate 7 and on the top inner side of the movable plate 44, and a buffer assembly 42 is provided between the first lead screw 41 and the guide rod 43.

[0019] By adopting the above technical solution, the structure can guide and limit the movement of the moving plate 44 through the guide rod 43, thereby preventing the moving plate 44 from deviating or rotating during the movement and ensuring the normal operation of the work.

[0020] Specifically, the buffer assembly 42 includes a connecting plate 423. Multiple connecting frame assemblies 2 are fixedly connected to the connecting plate 423 on the side near the moving plate 44 and between the first lead screw 41 and the guide rod 43. An elastic rubber frame 421 is fixedly connected between the connecting plate 423 and the moving plate 44. Multiple dampers 422 are fixedly connected between the connecting plate 423 and the moving plate 44 and inside the elastic rubber frame 421.

[0021] By adopting the above technical solution, users can buffer external collisions when needed through the cooperation of the elastic rubber frame 421 and the damper 422, thereby reducing the possibility of the connection becoming loose due to external collisions.

[0022] In this embodiment, when PVC panels 1 need to be installed on doors and windows for decoration or protection, the user needs to install the mounting plate 7 on the door / window body 6 using expansion bolts 5. Then, the user rotates the first lead screw 41 in the adjustable buffer device 4. The first lead screw 41 is threadedly connected to the moving plate 44, and the moving plate 44 is slidably connected to the guide rod 43. Therefore, the first lead screw 41 drives the moving plate 44 and its structure to move, thereby adjusting the position of each connecting frame assembly 2. During installation, the user can directly connect the PVC panels 1 to each connecting frame assembly 2 using the clip assemblies 3 to complete the installation connection. The elastic rubber frame 421 and damper 422 between the moving plate 44 and the connecting plate 423 in the buffer assembly 42 can buffer external impacts, thereby reducing the possibility of loosening of the connection. The entire connection process does not require electricity and is environmentally friendly.

[0023] Example 2 The difference between this embodiment and embodiment 1 is that the temporary fixing device 8 includes a clamping frame 81. The top and bottom outer sides of the PVC board 1 are both provided with clamping frames 81. A screw 84 is threadedly installed on the edge of the clamping frame 81 away from the door and window body 6. A clamping plate 83 is installed on the side of the screw 84 close to the PVC board 1 and located inside the clamping frame 81 via a bearing. A connecting box 87 is fixedly installed on both sides of the two clamping frames 81 that are far apart from each other. A second lead screw 85 is installed on the center of the connecting box 87 via a bearing. A moving block 86 is threadedly installed on the outer side of the second lead screw 85 and located inside the connecting box 87. Multiple suction cups 88 are fixedly installed on the side of the moving block 86 close to the door and window body 6.

[0024] By adopting the above technical solution, users can temporarily attach the PVC board 1 to doors and windows when needed by using the clamping frame 81 and suction cup 88, thereby better dealing with different situations.

[0025] Specifically, the two sides of the two clamping plates 83 that are far apart from each other are in contact with the inner sides of the two clamping frames 81.

[0026] By adopting the above technical solution, the structure can guide and limit the movement of the clamping plate 83 through the clamping frame 81, thereby preventing the clamping plate 83 from shifting or rotating during movement and ensuring the normal operation of the work.

[0027] Specifically, the inner side of the connecting box 87 and the outer side of the moving block 86 are fitted together.

[0028] By adopting the above technical solution, the structure can guide and limit the movement of the moving block 86 through the connecting box 87, thereby preventing the moving block 86 from shifting or rotating during movement and ensuring normal operation.

[0029] Specifically, a rubber layer 82 is fixedly installed on the side of the plywood 83 near the PVC board 1.

[0030] By adopting the above technical solution, the structure enhances the friction between the clamping plate 83 and the PVC plate 1 through the rubber layer 82, thereby better ensuring the normal operation of the clamping work and meeting the needs of the work.

[0031] In this embodiment, when it is necessary to temporarily connect the PVC board 1 to the door or window, the user places the clamping brackets 81 of the two temporary fixing devices 8 onto the PVC board 1, and then rotates the two screws 84 respectively. The screws 84 are threadedly connected to the clamping brackets 81, and the screws 84 are bearing-connected to the clamping plates 83. The clamping plates 83 and the clamping brackets 81 are in close contact with each other. Therefore, the two screws 84 drive the two clamping plates 83 and their rubber layers 82 to move, thereby cooperating with the two clamping brackets 81 to clamp the PVC board 1 and fix the position of the two clamping brackets 81. Then, the user rotates the two second lead screws 85 respectively. The second lead screws 85 are threadedly connected to the moving blocks 86, and the outer side of the moving blocks 86 is in close contact with the inner side of the connecting box 87. Therefore, the two second lead screws 85 drive the two moving blocks 86 and their suction cups 88 to move until each suction cup 88 disengages from the inner side of the two connecting boxes 87. Then, the user can temporarily attach the PVC board 1 to the door or window using the suction cups 88.

[0032] The structure and principle of the PVC board 1, the connecting frame assembly 2 consisting of a connecting frame, a groove and a buckle, the buckle assembly 3 consisting of a buckle head, an annular groove, a conical surface, a threaded head and a threaded groove, and the expansion bolt 5 in this utility model have been disclosed in a buckle connector for a PVC decorative board disclosed in announcement number CN210421744U. Its working principle is to use the connecting frame as the installation skeleton, and to achieve quick installation of the PVC board by setting up symmetrical buckles in the connecting frame and cooperating with the buckle head installed on the PVC board. Moreover, it is easy to replace. In addition, the buckle head design has good universality, and it can be replaced when damaged, without having to replace the entire PVC board.

[0033] The structure and principle of the damper 422, which consists of a cylinder, piston rod, piston, first pressure plate, second pressure plate, damping shaft, viscous fluid, first hollow screw, second hollow screw, pressure block, spring, first outer hole, first inner hole, second outer hole, second inner hole, pressure-bearing middle part, first pressure-bearing end, second pressure-bearing end, first guide part, second guide part, shaft body, direct flow channel, first head and second head, have been disclosed in the speed-adjustable damper disclosed in CN215673334U. Its working principle is that a uniform speed shaft is set on the piston to achieve a stable damping effect. A variable speed shaft is set on the piston, and the cross-sectional area of ​​the variable speed channel is set to be inversely proportional to the pressure value. This makes the cross-sectional area of ​​the variable speed channel smaller when the pressure increases, making it more difficult for the viscous fluid to flow, and ultimately resulting in a better damping effect.

[0034] The working principle and usage process of this utility model are as follows: When PVC panels 1 need to be installed on doors and windows for decoration or protection, the user needs to install the mounting plate 7 on the door / window body 6 using expansion bolts 5. Then, rotate the first lead screw 41 in the adjusting buffer device 4. The first lead screw 41 is threadedly connected to the moving plate 44, and the moving plate 44 is slidably connected to the guide rod 43. Therefore, the first lead screw 41 drives the moving plate 44 and its structure to move, thereby adjusting the position of each connecting frame assembly 2. During installation, the user can directly connect the PVC panel 1 to each connecting frame assembly 2 using the clip assemblies 3 to complete the installation connection. The elastic rubber frame 421 and damper 422 between the moving plate 44 and the connecting plate 423 in the buffer assembly 42 can buffer external impacts, thereby reducing the possibility of loosening of the connection. The entire connection process requires no electricity and is environmentally friendly. When it is necessary to temporarily connect the PVC panel 1... When attaching to doors and windows, the user places the clamping brackets 81 of the two temporary fixing devices 8 onto the PVC board 1, and then rotates the two screws 84 respectively. The screws 84 are threadedly connected to the clamping brackets 81, and the screws 84 are bearing-connected to the clamping plates 83. The clamping plates 83 and the clamping brackets 81 are in close contact with each other. Therefore, the two screws 84 drive the two clamping plates 83 and their rubber layers 82 to move, thereby cooperating with the two clamping brackets 81 to clamp the PVC board 1 and fix the position of the two clamping brackets 81. Then, the user rotates the two second lead screws 85 respectively. The second lead screws 85 are threadedly connected to the moving blocks 86, and the outer side of the moving blocks 86 is in close contact with the inner side of the connecting box 87. Therefore, the two second lead screws 85 drive the two moving blocks 86 and their suction cups 88 to move until each suction cup 88 disengages from the inner side of the two connecting boxes 87. Then, the user temporarily attaches the PVC board 1 to the door or window using the suction cups 88.
