[0002] Aluminum veneer refers to a kind of building decoration material with aluminum plate as the base material, formed by CNC bending and other technologies, and then surface treated. It is made of a layer of aluminum plate and can be processed into various shapes and sizes according to needs. The surface treatment is diverse, including spraying, roller coating and other treatment methods. It is commonly used in building exterior walls, curtain walls, interior decoration and other fields. It has the advantages of strong weather resistance, good fire resistance, easy processing and installation.

[0003] In the prior art, aluminum veneers are connected to connecting pages through bolts, and then connected to walls or components through the connecting pages. When aluminum veneers are used in the construction of curtain walls and exterior walls of buildings, the aluminum veneers will be washed by rainwater. Since the bolts and the connecting pages are tightly connected, it is difficult for external rainwater to corrode the aluminum veneer from one side of the connecting page. However, after long-term use, rainwater is easy to flow into the side of the aluminum veneer close to the wall, and the rainwater will flow into the gap between the bolt and the aluminum veneer through the thread of the bolt, thereby corroding the drilling position of the aluminum veneer. The corroded aluminum veneer is therefore loosely connected to the connecting page, which can easily cause the aluminum veneer to fall off. Utility Model Content

The outer wall of the positioning bar 41 is slidably connected to the outer wall of the aluminum plate 1, the top of the trapezoidal block 42 contacts the bottom of the aluminum plate 1, and the outer wall of the connecting plate 43 is fixedly connected to the outer wall of the fixing tube 6. The blocking block 5 is fixed by the position of the positioning frame 4, so that the shielding effect of the blocking block 5 is difficult to be broken by external force, and the shielding of the blocking block 5 makes it difficult for rainwater to enter the threaded connection position of the bolt 3 and the aluminum plate 1, which has the effect of preventing rainwater from entering and corroding the connection, and preventing the connection from loosening due to rainwater corrosion.

[0019] The fixing device 44 includes a compression spring 444, both ends of which are fixedly connected with sliding columns 442, the outer wall of the sliding column 442 is slidably connected to the inner wall of the connecting plate 43 through a movable groove 443, and the movable groove 443 is opened in the wall of the connecting plate 43, and the end of the sliding column 442 away from the compression spring 444 is fixedly connected with a sliding block 441, the outer wall of the sliding block 441 is slidably connected to the inner wall of the connecting plate 43, and the outer wall of the sliding block 441 is slidably connected to the inner wall of the fixing cylinder 6. In the process of pushing the positioning frame 4 into the aluminum plate 1, the fixing cylinder 6 will squeeze the sliding block 441 of the fixing device 44, so that the sliding block 441 shrinks in the connecting plate 43 and squeezes the compression spring 444 until the top of the positioning frame 4 is completely in contact with the bottom of the aluminum plate 1, the compression spring 444 pushes the sliding column 442 to move, so that the sliding column 442 pushes the sliding block 441 along the direction of the movable groove 443, so that the sliding block 441 slides into the inside of the fixing cylinder 6, and completes the fixation of the positioning frame 4.

[0020] The connecting page 2 includes an L-shaped plate 21, and an insert plate 22 is fixedly connected to the top of the L-shaped plate 21. A positioning groove 23 is opened in the wall of the insert plate 22. The outer wall of the insert plate 22 is slidingly connected to the inner wall of the aluminum plate 1 through the insert groove 11, and the insert groove 11 is opened in the wall of the aluminum plate 1. The outer wall of the bolt 3 is slidingly connected to the inner wall of the L-shaped plate 21, and the outer wall of the bolt 3 is threadedly connected to the inner wall of the aluminum plate 1. During the movement of the connecting page 2, the insert plate 22 is moved into the interior of the aluminum plate 1 until the outer wall of the L-shaped plate 21 and the outer wall of the aluminum plate 1 are fitted together. When the positioning frame 4 is pushed into the aluminum plate 1, the raised part on the positioning strip 41 will enter the positioning groove 23 of the insert plate 22 and contact the bottom of the aluminum plate 1. If the connecting page 2 is not fully pushed in or the L-shaped plate 21 is not fully fitted to the outer wall of the aluminum plate 1, the positioning strip 41 will not be able to enter the positioning groove 23.

[0021] The blocking block 5 includes a blocking strip 51, the outer wall of the blocking strip 51 is fixedly connected with a triangular block 52, the outer wall of the triangular block 52 is fixedly connected with a limiting strip 53, the outer wall sliding groove 12 of the triangular block 52 is slidably connected to the inner wall of the aluminum plate 1, and the sliding groove 12 is opened in the wall of the aluminum plate 1, the blocking block 5 slides in the sliding groove 12 in the aluminum plate 1, and pushes the positioning frame 4 into the aluminum plate 1. At this time, the trapezoidal block 42 on the positioning strip 41 enters the sliding groove 12 position. Due to the inclined surface setting of the trapezoidal block 42, the trapezoidal block 42 squeezes the triangular block 52 toward both sides. During the extrusion process, the triangular block 52 drives the limiting strip 53 to move, and at the same time the blocking strip 51 reaches the bottom of the protruding part of the bolt 3, and forms a closed space by cooperating with the shape of the aluminum plate 1, and the protruding threaded part of the bolt 3 is accommodated in the closed space.

[0022] Working principle:

[0023] When in use, the bolt 3 will fix the connecting page 2 on the aluminum plate 1. At this time, the part of the bolt 3 extending out of the aluminum plate 1 is in the sliding groove 12. The positioning frame 4 is pushed into the aluminum plate 1. At this time, the trapezoidal block 42 on the positioning bar 41 enters the sliding groove 12. At the same time, the shielding block 5 slides in the sliding groove 12 in the aluminum plate 1. Due to the inclined surface setting of the trapezoidal block 42, the trapezoidal block 42 squeezes the triangular block 52 toward both sides. During the squeezing process, the triangular block 52 drives the limiting bar 53 to move. At the same time, the shielding bar 51 reaches the bottom of the protruding part of the bolt 3, and forms a closed space by matching the shape of the aluminum plate 1, and the threaded part of the bolt 3 extending out is stored in the closed space. At the same time, the connecting plate 43 is already between the fixing tubes 6. When the connecting plate 43 is in the fixing tube 6 During the movement before clamping, the fixing cylinder 6 squeezes the slider 441 of the fixing device 44, so that the slider 441 shrinks in the connecting plate 43 and squeezes the compression spring 444. Until the top of the positioning frame 4 and the bottom of the aluminum plate 1 are completely in contact, the compression spring 444 pushes the sliding column 442 to move, so that the sliding column 442 pushes the slider 441 along the direction of the movable groove 443, so that the slider 441 slides into the fixing cylinder 6, and the positioning frame 4 is fixed. Since the position of the positioning frame 4 is fixed, the shielding effect of the shielding block 5 is difficult to be broken by external force. Through the shielding of the shielding block 5, it is difficult for rainwater to enter the threaded connection position of the bolt 3 and the aluminum plate 1, which prevents rainwater from entering and corroding the connection, and prevents the connection from loosening due to rainwater corrosion.

[0024] Insert the connecting page 2 into the aluminum plate 1 through the insertion groove 11. During the movement of the connecting page 2, move the insertion plate 22 into the aluminum plate 1 until the outer wall of the L-shaped plate 21 fits with the outer wall of the aluminum plate 1. When the positioning frame 4 is pushed into the aluminum plate 1, the raised portion of the positioning bar 41 will enter the positioning groove 23 of the insertion plate 22 and contact the bottom of the aluminum plate 1. If the connecting page 2 is not fully pushed in or the L-shaped plate 21 is not fully fitted with the outer wall of the aluminum plate 1, the positioning bar 41 will not be able to enter the positioning groove 23. At this time, due to the obstruction of the positioning groove 23, The slider 441 of the fixing device 44 cannot enter the fixing tube 6, making the fixing device 44 ineffective. Therefore, whether the connecting page 2 is completely in contact with the aluminum plate 1 can be judged by whether the positioning frame 4 is fixed or not. If the positioning frame 4 and the fixing tube 6 of the aluminum plate 1 are fixed to each other, the connecting page 2 and the aluminum plate 1 will be completely in contact with each other. When the operator performs drilling, there is no need to worry about the connection page 2 being skewed during drilling, causing the drilling hole to be offset, thereby preventing the unstable connection of the aluminum plate 1 caused by the drilling offset, and further preventing the aluminum plate 1 from falling off after installation on the exterior wall of the building.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
